    Planning and Sequencing Through Multimodal Interaction for Robot Programming2014Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Over the past few decades the use of industrial robots has increased the efficiency as well as the competitiveness of several sectors. Despite this fact, in many cases robot automation investments are considered to be technically challenging. In addition, for most small and medium-sized enterprises (SMEs) this process is associated with high costs. Due to their continuously changing product lines, reprogramming costs are likely to exceed installation costs by a large margin. Furthermore, traditional programming methods of industrial robots are too complex for most technicians or manufacturing engineers, and thus assistance from a robot programming expert is often needed. The hypothesis is that in order to make the use of industrial robots more common within the SME sector, the robots should be reprogrammable by technicians or manufacturing engineers rather than robot programming experts. In this thesis, a novel system for task-level programming is proposed. The user interacts with an industrial robot by giving instructions in a structured natural language and by selecting objects through an augmented reality interface. The proposed system consists of two parts: (i) a multimodal framework that provides a natural language interface for the user to interact in which the framework performs modality fusion and semantic analysis, (ii) a symbolic planner, POPStar, to create a time-efficient plan based on the user's instructions. The ultimate goal of this work in this thesis is to bring robot programming to a stage where it is as easy as working together with a colleague.This thesis mainly addresses two issues. The first issue is a general framework for designing and developing multimodal interfaces. The general framework proposed in this thesis is designed to perform natural language understanding, multimodal integration and semantic analysis with an incremental pipeline. The framework also includes a novel multimodal grammar language, which is used for multimodal presentation and semantic meaning generation. Such a framework helps us to make interaction with a robot easier and more natural. The proposed language architecture makes it possible to manipulate, pick or place objects in a scene through high-level commands. Interaction with simple voice commands and gestures enables the manufacturing engineer to focus on the task itself, rather than the programming issues of the robot. The second issue addressed is due to inherent characteristics of communication with the use of natural language; instructions given by a user are often vague and may require other actions to be taken before the conditions for applying the user's instructions are met. In order to solve this problem a symbolic planner, POPStar, based on a partial order planner (POP) is proposed. The system takes landmarks extracted from user instructions as input, and creates a sequence of actions to operate the robotic cell with minimal makespan. The proposed planner takes advantage of the partial order capabilities of POP to execute actions in parallel and employs a best-first search algorithm to seek the series of actions that lead to a minimal makespan. The proposed planner can also handle robots with multiple grippers, parallel machines as well as scheduling for multiple product types.

    Towards Creation of Robot Programs Through User InteractionArticle in journal (Other academic)
    Abstract [en]

    This paper proposes a novel system for task-level programming of industrial robots. The user interacts with an industrial robot by giving instructions in a structured natural language and by selecting objects through an augmented reality interface. The proposed system consists of two parts. First, a multimodal framework that provides a natural language interface to the user. This framework performs modality fusion, semantic analysis and helps the user to interact with the system easier and more naturally. The proposed language architecture makes it possible to manipulate, pick or place objects in a scene through high-level commands. The second component is the POPStar planner, which is based on partial order planner (POP), that takes landmarks extracted from user instructions as input, and creates a sequence of actions to operate the robotic cell with minimal makespan. The proposed planner takes advantage of partial order capabilities of POP to plan execution of actions in parallel and employs a best-first search algorithm to seek a series of actions that lead to a minimal makespan. The proposed planner can as well handle robots with multiple grippers, and  parallel machines. Using different topologies for the landmark graphs, we show that it is possible to create schedules for changing object types, which are processed in different stages in the robot cell. Results show that the proposed system can create and adapt schedules for robot cells with changing product types in low volume production based on the user's instructions.

    Scheduling for Multiple Type Objects Using POPStar Planner2014In: Proceedings of the 19th IEEE International Conference on Emerging Technologies and Factory Automation (ETFA'14), Barcelona, Spain, September, 2014, 2014, p. Article number 7005148-Conference paper (Refereed)
    Abstract [en]

    In this paper, scheduling of robot cells that produce multiple object types in low volumes are considered. The challenge is to maximize the number of objects produced in a given time window as well as to adopt the  schedule for changing object types. Proposed algorithm, POPStar, is based on a partial order planner which is guided by best-first search algorithm and landmarks. The best-first search, uses heuristics to help the planner to create complete plans while minimizing the makespan. The algorithm takes landmarks, which are extracted from user's instructions given in structured English as input. Using different topologies for the landmark graphs, we show that it is possible to create schedules for changing object types, which will be processed in different stages in the robot cell. Results show that the POPStar algorithm can create and adapt schedules for robot cells with changing product types in low volume production.

    Augmented Reality-based Industrial Robot Control2011In: Proceedings of SIGRAD 2011 / [ed] Larsson, Thomas ; Kjelldahl, Lars ; Jää-Aro, Kai-Mikael, Linköping University Electronic Press, 2011, p. 113-114Conference paper (Refereed)
    Abstract [en]

    Most of the interfaces which are designed to control or program industrial robots are complex and require special training for the user. This complexity alongside the changing environment of small medium enterprises (SMEs) has lead to absence of robots from SMEs. The costs of (re)programming the robots and (re)training the robot users exceed initial costs of installation. In order to solve this shortcoming, we propose a new interface which uses augmented reality (AR) and multimodal human-robot interaction. We show that such an approach allows easier manipulation of robots at industrial environments.

    Intuitive Industrial Robot Programming Through Incremental Multimodal Language and Augmented Reality2011In: 2011 IEEE International Conferance on Robotics and Automation (ICRA 2011), IEEE , 2011, p. 3934-3939Conference paper (Refereed)
    Abstract [en]

    Developing easy to use, intuitive interfaces is crucial to introduce robotic automation to many small medium sized enterprises (SMEs). Due to their continuously changing product lines, reprogramming costs exceed installation costs by a large margin. In addition, traditional programming methods for industrial robots is too complex for an inexperienced robot programmer, thus external assistance is often needed. In this paper a new incremental multimodal language, which uses augmented reality (AR) environment, is presented. The proposed language architecture makes it possible to manipulate, pick or place the objects in the scene. This approach shifts the focus of industrial robot programming from coordinate based programming paradigm, to object based programming scheme. This makes it possible for non-experts to program the robot in an intuitive way, without going through rigorous training in robot programming.

    Scheduling POP-Star for Automatic Creation of Robot Cell Programs2013Conference paper (Refereed)
    Abstract [en]

    Typical pick and place, and machine tending applications often require an industrial robot to be embedded in a cell and to communicate with other devices in the cell. Programming the program logic is a tedious job, requiring expert programming knowledge, and it can take more time than programming the specific robot movements itself. We propose a new system, which takes in the description of the whole manufacturing process in natural language as input, fills in the implicit actions, and plans the sequence of actions to accomplish the task described in minimal makespan using a modified partial planning algorithm. Finally we demonstrate that the proposed system can come up with a sensible plan for the given instructions.

    Object Selection using a Spatial Language for Flexible Assembly2009In: 14th IEEE International Conference on Emerging Technologies and Factory Automation, 2009. (ETFA 2009), Mallorca, Spain, 2009Conference paper (Refereed)
    Abstract [en]

    In this paper we present a new simplified natural language that makes use of spatial relations between the objects in scene to navigate an industrial robot for simple pick and place applications. Developing easy to use, intuitive interfaces is crucial to introduce robotic automation to many small medium sized enterprises (SMEs). Due to their continuously changing product lines, reprogramming costs are far higher than installation costs. In order to hide the complexities of robot programming we propose a natural language where the use can control and jog the robot based on reference objects in the scene. We used Gaussian kernels to represent spatial regions, such as left or above. Finally we present some dialogues between the user and robot to demonstrate the usefulness of the proposed system.

    Miljövänligare inflygningar2011Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

     Detta examensarbete handlar om miljövänligare inflygningar. Gröna- och kurvade inflygningar gör flyget mer miljövänligt. Det är ett effektivt sätt att minska flygets miljöpåverkan. Varje grön- och kurvad inflygning innebär minskad bränsleförbrukning, utsläpp samt betydligt lägre buller vid landning.

     Vid en grön inflygning, sjunker flygplanet kontinuerligt från sin marschhöjd till landningsbanan med motorerna på tomgång. En kurvad inflygning är en kombination av grön inflygning och kurvad inflygning. Med en kurvad inflygning kan man välja en väg där man inte flyger över bostadsområde. På så sätt blir det inga köbildningar i luften innan landningen. Vid kurvade inflygningar blir miljövinster större än med vanliga gröna inflygningar.

    För att ett flygplan skall kunna genomföra en grön inflygning krävs att det är utrustad med FMS (Flight Management System). Det är utrustning för navigering som bestämmer flygplants position genom att integrera navigationsuppgifter från en eller flera positionsgivare med information från flygplants fartmätar- och höjdmätarsystem.

    Flygvägar som SID och STAR skapar flygsäkerhet och ordning i luftrummet. SID är flygvägar för angående trafik och STAR är flygvägar för ankommande trafik. Syftet med P-RNAV STAR är att ett flygplan med navigeringsutrustning ska kunna programmera in färdvägen i sin FMS och på så sätt genomförs en optimal inflygning med låga koldioxidutsläpp.

    Gröna inflygningar har visat kunnat spara 100-150 kilo bränsle och 314-474 kilo koldioxidutsläpp vid varje miljövänlig inflygning beroende på flygplansmodell.

    Head-worn Mixed Reality Projection Display Application2014In: ACM International Conference Proceedings Series (ICPS), 2014Conference paper (Refereed)
    Abstract [en]

    The main goal of this research is to develop a mixed real- ity (MR) application to support motion capture actors. This application allows seeing and exploring a digital environment without occluding the actor’s visual field. A prototype is built by combining a retro-reflective screen covering surrounding walls and a headband consisting of a laser scanning projector with a smartphone. Built-in sensors of a smartphone provide navigation capabilities in the digital world. The integrated system has some unique advantages, which are collectively demonstrated for the first time: (i) providing fixed field-of- view (50o in diagonal), fixed retinal images at full-resolution, and distortion-free images that are independent of the screen distance and shape; (ii) presenting different perspectives to the users as they move around or tilt their heads, (iii) allow- ing a focus-free and calibration-free display even on non-flat surfaces using laser scanning technology, (iv) enabling mul- tiple users to share the same screen without crosstalk due to the use of retro-reflectors, and (v) producing high brightness pictures with a projector of only 15 lm; due to a high-gain retro-reflective screen. We demonstrated a lightweight, com- fortable to wear and low cost head-mounted projection dis- play (HMPD) which acts as a stand-a-lone mobile system. Initial informal functionality tests have been successfully per- formed. The prototype can also be used as a 3D stereo system using the same hardware by additionally mounting polarized glasses and an active polarization rotator, while maintaining all of the advantages listed above.

    Framtida installationskrav på Electronic Flight Bags (EFB): Med hänsyn till litiumbatterier2017Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This degree project studies the future regulations for the installation of electronic flight bags (EFB) with focus on the hardware and its safety implications in which the task was given by Bromma Air Maintenance (BAM). The aim is to ease the operator to handle issues dealing with EFB; such as lithium battery fire in the cockpit, placement of EFB in the cockpit, etc. This also addresses flight safety, flight controls, emergency evacuation and solutions in dealing with such issues. Flight safely is a vital factor to be considered since it jeopardizes lives. As recent reports indicate an increase in lithium battery powered devices incidents on aircrafts, this paves the way to find new solutions and procedures to mitigate them. By studying the current regulations, Acceptable Means of Compliance (AMC), Advisory Circular (AC) regarding the usage/installation of EFB and future regulation draft (NPA) this study analyzed the changes, which indicated that there were not many significant changes made to the future regulation (new AMC). Although many chapter of the current AMC have been removed and introduced into a new section under AMC & GM (Guidance Material). Different placement of the EFB in cockpit has also been studied in this degree project, which has shown that depending on the placement choice of the aircraft operator there are advantages and disadvantages. This follows by studying the lithium (Li-ion) batteries: technology, mitigation of fire and procedures for lithium battery fire while also studying the recent incidents regarding lithium batteries fire and explosion in commercial and cargo flights. The solutions consist of using the latest technology to propose a new approach to charge the batteries, and store the burning batteries as well. This lead to a smart inductive charger and a smart fire contamination bag to be integrated into the procedures.

    The new standard for innovation management systems: A comparative study of Volvo Construction Equipment's innovation management system and CEN/TS standardized innovation management system2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study is to analyze Volvo CE´s current innovation management strategy and compare it with the European Committee for Standardization´s (CENT/TS) standardized innovation management system. The study can be helpful for the organization to understand the gap between their current management system and the recommendations found in the CEN/TS innovation management system. A qualitative research methodology with a deductive approach combined with action research has been used to answer and fulfill the research question and purpose of this study. Our theoretical framework will introduce the five areas presented in CEN/TS IMS (2013) and describe their content more detailed with help from theoretical frameworks related to these areas. We will also consider other theorist's perspectives and compare their thoughts, description and models with what is been described in the CEN/TS regarding these five areas.Empiricism: Interviews with three of Volvo CE´s innovation coaches has been made to gain an understanding about the current status of the company´s innovation management strategies related to the requirements the five areas mentioned within CEN/TS IMS. In the Analysis section, a gap analysis has been made between Volvo CE´s current innovation management strategies and the requirements of the CEN/TS IMS for each area covered by this study. Overall, we think that Volvo CE have a good potential to develop a fully functional IMS in accordance with the requirements of CEN/TS 16555-1 into their organization with their current innovation management model as a starting point to build upon, and by following the references and recommendations provided by this study, the company has great chances in succeed with this mission

    Abstract [en]

    Executing software processes in the cloud can bring several benefits to software development. In this paper, we discuss the benefits and considerations of cloud-based software processes. EXE-SPEM is our extension of the Software and Systems Process Engineering (SPEM2.0) Meta-model to support creating cloud-based executable software process models. Since SPEM2.0 is a visual modelling language, we introduce an XML notation meta-model and mapping rules from EXE-SPEM to this notation which can be executed in a workflow engine. We demonstrate our approach by modelling an example software process using EXE-SPEM and mapping it to the XML notation.

    Towards cloud-based enactment of safety-related processes2016In: Lecture Notes in Computer Science, vol. 9922, 2016, p. 309-321Conference paper (Refereed)
    Abstract [en]

    Engineering safety-critical systems is a complex task which involves multiple stakeholders. It requires shared and scalable computation to systematically involve geographically distributed teams. The paper proposes a model-driven cloud-based enactment architecture automating safety-critical processes. This work adapts our previous work on cloud-based software engineering by enriching the architecture with an automatic support for generation of both, product-based safety arguments from failure logic analysis results and process-based arguments from the process model and the enactment data. The approach is demonstrated using a fragment of a process adapted from the aerospace domain.

    Software development in the Post-PC era: Towards software development as a service2016In: Lect. Notes Comput. Sci., 2016, p. 662-671Conference paper (Refereed)
    Abstract [en]

    Over the years, software development has evolved to meet the needs of new types of applications and to embrace new technological disruptions. Today, we witness the rise of mobility where the role of the conventional high-end PC is declining. Some refer to this era as the Post- PC era. This technological shift, powered by a key enabling technology, cloud computing, has opened new opportunities for human advancement. Consequently, the evolving landscape of software systems drives the need for new methods for conceiving them. Such methods need to: (a) address the challenges and requirements of this era and (b) embrace the benefits of new technological breakthroughs. In this paper, we list the characteristics of the Post-PC era from the software development perspective and describe two motivating trends of software development processes. Then, we derive a list of requirements for the future software development from the characteristics of the Post-PC era and from the motivating trends. Finally, we propose a reference architecture for cloud-based software process enactment as an enabler for Software Development as a Service. The architecture is the first step addressing the needs that we have identified.

    Enabling GSD Task Allocation via Cloud-based Software Processes2017In: Software Engineering Research, Management and Applications SERA-2017, Springer, 2017, p. 179-192Conference paper (Refereed)
    Abstract [en]

    Allocating tasks to distributed sites in Global Software Development (GSD) projects is often done unsystematically and based on the personal experi- ence of project managers. Wrong allocation decisions increase the project’s risks as tasks have dependencies that are inherited by the distributed sites. Decision sup- port can help make the task allocation a more informed and systematic process. The challenges in allocating tasks to distributed sites exist because of three dis- tance dimensions between sites (geographical, temporal and cultural). An informed task allocation decision needs to consider these distances. Therefore, in this paper, we propose to integrate and semi-automate the calculation of an existing Global Distance Metric (GDM) into an architecture that supports executing cloud-based software processes. We analyze the potential of integrating the GDM into this archi- tecture and identify the needed extensions to the architecture.

    Allocating tasks to distributed sites in Global Software Development (GSD) projects is often done unsystematically and based on the personal experience of project managers. Wrong allocation decisions increase the project’s risks as tasks have dependencies that are inherited by the distributed sites. Decision support can help make the task allocation a more informed and systematic process. The challenges in allocating tasks to distributed sites exist because of three distance dimensions between sites (geographical, temporal and cultural). An informed task allocation decision needs to consider these distances. Therefore, in this paper, we propose to integrate and semi-automate the calculation of an existing Global Distance Metric (GDM) into an architecture that supports executing cloud-based software processes. We analyze the potential of integrating the GDM into this architecture and identify the needed extensions to the architecture.

    Sustainable production adoption by Surface Treatment SMES: challenges and enablers2015In: Global Cleaner Production & Sustainable Consumption Conference 2015 GCPC2015, 2015Conference paper (Refereed)
    Abstract [en]

    The adoption to sustainable production is a continuous but necessary strive for manufacturing operations, including small and medium enterprises, SMEs. Meeting the future needs of the economic, social and environmental dimensions provides challenges for SMEs. In order to meet these challenges, understanding of internal and external enablers is required. Studies focusing on the enablers for sustainability among SMEs are rare; hence these companies are important players in the supply chain to focal companies. In order to enhance the understanding of the adoption of sustainable production for the sector surface treatment SMEs, an exploratory study has been conducted. In this study, the focus has been placed in the identification and analysis of the challenges and enablers for adoption of sustainable production. Two stages of empirical data collection were undertaken: a focus group session and an online questionnaire. The findings present challenges based on the limitations of the surface treatment process but also where enablers for the social, economic and environmental for meeting those challenges are interrelated. The results showed that these SMEs face challenges in their way towards sustainable production, mainly due to: low economic profitability, need for improvement in old working procedures, lack of fully understanding regarding environmental legislation, difficulty in ensuring workforce, lack of technology development and resistance towards change. These challenges could be faced through internal and external enablers, where the support of large-size customers and other stakeholders is critical for this sector.

    Conceptual sustainable production principles in practice: Do they reflect what companies do?2017In: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 141, p. 693-701Article in journal (Refereed)
    Abstract [en]

    A common understanding of sustainable production principles and the identification of sustainable manufacturing practices among practitioners are key starting points in studying how manufacturers are making their operations more sustainable. However, there is a lack of insight in the literature connecting conceptual sustainable production principles, and the practices reflecting these principles. Using semi-structured interviews founded on the sustainable production principles posed by the Lowell Center for Sustainable Production, this paper presents an outlook of how companies in different industries carry out manufacturing practices related to the sustainability production principles. Results showed that the majority of sustainable manufacturing practices remain strongly centered on the environmental dimension of sustainability, with the greatest number of practices emanating from principles concerning energy and material conservation, and waste management. Similarly, reactive sustainable manufacturing practices prevailed over proactive sustainable manufacturing practices, as most of the practices aimed to comply with regulatory and market pressures. Quality and environmental management systems were acknowledged as important tools for putting sustainable production principles into practice; while Swedish environmental and social regulations were found to drive sustainable manufacturing practices. This study connects sustainable production principles with sustainable manufacturing practices and opens the way for further studies on a global or sector-specific scale.

    Spare parts management potential in production2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Spare parts management (SPM) is an important branch of management which could lead the company to success or bankruptcy. It is also fill of potential improvements that can increase the company profits, productivity, and reliability. Wise inventory management would eliminate all the delay risks of unplanned breakdowns, and reduce process time and cost.

    To understand the importance of the spare parts, a fundamental knowledge of maintenance types, spare parts, spare parts management, spare parts classifications, ABC analysis, Economic order quantity, suppliers’ management, purchase management, and management computer program SAP, have been viewed.

    Companies realize the spare parts importance and try to develop the system to increase the benefits. Many ways has been taken to achieve that. Each company has it is own management system that the company has developed in years.

    In this research, spare parts management system of seven companies has been studied. By comparing of the management systems, we highlight the areas that would have negative or positive impact on the system. We would also analysis why the companies have chosen these systems, how they develop the system, and where they aim throw the development.

    Reviewing case studies would have many advantages, it would expand the vision to develop the management system and focus on the points that have permanent value instead of focus on temporary improvement.

    Two check lists of points that could have potential improvement, have been presented and in which improvement type.

    Economic lifetime prediction of a mining drilling machine using an artificial neural network2014In: International Journal of Mining, Reclamation and Environment, ISSN 1748-0930, E-ISSN 1748-0949, Vol. 28, no 5, p. 311-322Article in journal (Refereed)
    Abstract [en]

    This study develops models for predicting the economic lifetime of drilling machines used in mining. It uses three cases, each represented by a MATLAB code, to develop an optimisation model. The resulting ORT is fed as input to an artificial neural network (ANN) and the results translated into a relatively simple equation. The study finds that increasing the purchase price and decreasing the operating and maintenance costs will increase a machine's ORT linearly. Decreased maintenance cost has the largest impact on ORT, followed by increased purchase price and decreased operating cost. The ANN method gives a series of basic weight and response functions which can be made available to any engineer without the use of complicated software. It also helps decision-makers determine the best time economically to replace an old machine with a new one; thus, it can be extended to more general applications in the mining industry.

    Probabilistic Scheduling and Adaptive Relaying for WirelessHART Networks2015In: 20th IEEE International Conference on Emerging Technologies and Factory Automation ETFA'15, 2015Conference paper (Refereed)
    Abstract [en]

    This paper deals with a way to probabilistically guarantee reliable packet delivery in WirelessHART based networks suitable for industrial control systems. We propose a new scheduling scheme, called Iterative Probabilistic Scheduling with Adaptive Relaying (IPS-AR), which consists of a static part (IPS) and a dynamic part (AR). IPS takes into account the channel characteristics and exploits relaying to achieve a minimum reliability threshold as requested by the supported industrial application. In the AR part, each relay node decides the packet to be sent based on online assessment of both the number of consecutive errors experienced by previous packets belonging to the same flow, as well as the number of copies of the packet currently available at the other relay nodes. This enables IPS-AR to achieve the desired reliability level while using the available re-sources in terms of time and bandwidth more efficiently.

    Abstract [en]

    This is a study in how a room for recycling can be designed as a way tocommunicate and make it easier for users to sort their waste. The long-termgoal for the room is to further encourage the users and increase their interestfor recycling. For this study a room for recycling at SGS Studentbostäder inGothenburg has been chosen. Currently, the room does not communicate itspurpose clearly, and has several problems causing low usability.The main focus of this study is to improve the usability of the room, and also tomake it more attractive. The research question that has been answered is “Howcan a recycling room be designed so that it can communicate and make it easierfor the user to quickly and efficiently sort their waste; and thus become moreusable?”By combining the results of both a literature review and empirical investigations,this study have resulted in two different design suggestions for the investigatedroom. Both design suggestions addresses the problems that were identified duringthe empirical study of the room, but in slightly different ways depending on thelevel of change that is wanted by the property owner. The overarching design ideahas been to introduce a clear and thorough color coding, with attention to smalldetails that have big impact.

    Ta på historien - inkluderande design på museum2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Detta arbete redogör för hur en stadshistorisk utställning kan utformas för att kommunicera sitt innehåll till målgruppen utrikes födda med bristande kunskaper i svenska. Undersökningen mål är att hitta riktlinjer som visualiserar ett koncept för denna typ av utställning. I undersökningen behandlas den lokalhistoriska utställningen ”Se Eskilstuna” på Eskilstuna stadsmuseum. Utställningen används idag som undervisningsmaterial för studenter från SFI; svenska för invandrare. Idag har utställningen brister som gör att den inte uppfyller den specifika målgruppens behov. Genom låg kontrast och struktur samt att den idag till stor del utgår från text, försvåras möjligheten att kommunicera sitt innehåll till målgruppen. I detta arbete diskuteras främst utställningens rumsliga formgivning, men även hur innehållet påverkar förståelsen för utställningen. Syftet med arbetet är att undersöka hur en utställning på bästa sätt kan förmedla information om platsen och platsens historia, utan att enbart förlita sig till kompletterande text-information. Detta för att underlätta för målgruppen att ta till sig innehållet. Med hjälp av tydligare struktur, och genom att skapa grupperingar och ett visuellt narrativ, skapas ökade förutsättningar för målgruppen att ta till sig utställningens innehåll. I undersökningen kombineras teorier om kognitiva processer, distribuerad kognition och affordans som vetenskaplig utgångspunkt. Genom kvalitativa metoder i form av fokusgrupp och öppen observation har en förståelse för målgruppen och dess behov skapats. Genom en platsanalys har brister i den existerande utställningsmiljön identifierats och en förståelse för rummet formulerats. Med stöd av litteratur och metodresultat har sedan ett designförslag skapats.

    Litteratur och intervjustudie inom Green Production: Vad skiljer Lean Production från Green Production, hur uppfattas arbete med miljöförbättrande åtgärder och vilka problem kan uppstå vid implementering av ett grönt produktionssätt?2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Följande rapport är resultatet av det examensarbete som utförts våren 2011 inom innovativ produktion/logistik vid Mälardalens Högskola. Examensarbete behandlar ämnet Green Production med fokus på skillnader mellan ett produktionssystem som bygger på Lean Production och ett som bygger på Green Production. Områden som berörs i rapporten är de verktyg som används i de olika produktionssystemen, hur arbetet med miljöförbättrande åtgärder kan se ut i praktiken samt vilka svårigheter som finns vid arbete med miljöförbättrande åtgärder i ett företag. Examensarbetet består av en litteraturstudie där aktuell litteratur studerats inom området samt en intervjustudie som genomförts med insatta inom miljöfrågor kopplat till produktion samt operatörer.

    Bakgrunden till examensarbetet grundar sig i att världen står inför en framtid där många utav de råmaterial som används idag vid produktion inte kommer att kunna nyttjas i framtiden. Detta i kombination med de miljöproblem som människan åsamkat, har bidragit till att många företag insett att miljöaspekter måste vara i åtanke genom hela produktionsprocessen.

    Den uppfattning som erhållits genom intervjustudierna är att det är viktigt för ett företag att visa att de arbetar med miljöförbättrande åtgärder. Detta brukar oftast genomföras genom att företag arbetar utefter olika standarder och miljömål, till exempel ISO 14000. Nackdelen med denna typ av miljöarbete är att företag tenderar till att fastställa olika miljömål på en relativt låg nivå. Detta innebär att företag som utger sig för att arbeta miljötillvänt kanske inte gör det i slutändan. Slutsatsen utav detta är att många företag i många fall kan tycka att det är viktigt att visa att de arbetar med miljötillvända åtgärder, men kanske inte är villiga att investera i de insatser som krävs för att till fullo bli miljömässigt korrekta.

    Utifrån den litteraturstudie och intervjustudie som utförts i examensarbetet har det kunnat konstateras att Green Production är en relativt ung produktionsfilosofi med ett ostrukturerat arbetssätt i jämförelse med Lean Production. På grund utav detta har det uttryckts att företag i viss mån utformat sina egna metoder och egna verktyg för att bedriva ett miljöarbete. De mest markanta skillnaderna som upptäckts genom studierna för examensarbetet har varit att Lean Production till störst del fokuserar på själva produktionsprocessen, medan Green Production till större del fokuserar på in och utloppet i processen samt har i större mån ett livscykelperspektiv på produktionen. Insatta på området uttrycker att det finns vissa svårigheter i arbetet med miljöförbättrande åtgärder. Dessa svårigheter är kopplade till ekonomiaspekter i företag, okunskap inom ämnet samt att uppfattningen är att de miljömässiga fördelar som erhålls genom Lean Production är tillräckliga. Dessa aspekter medför att många företag agerar passivt inom området. För att avhjälpa detta krävs det att företag erhåller utbildning inom området, så att de inser vikten av ett miljötillvänt arbetssätt samt vilka fördelar som kan erhållas genom ett produktionssystem som bygger på Green. Det kan även vara en fördel om de miljöledningssystem samt lagar som existerar idag vore striktare och ställde krav på i vilken mån som miljömål skall uppnås.

    Open Innovation inom offentlig förvaltning2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Open Innovation är ett relativt nytt arbetssätt som innebär att organisationer tar in extern kunskap med syftet att utveckla interna processer och vidga den egna kompetensen. Studien utgår ifrån ett kvalitativt perspektiv där relevanta teorier hämtats ifrån tryckt litteratur, vetenskapliga artiklar samt empiri som består av en omvärldsanalys samt intervjustudie med ett antal individer med varierande kunskap inom områdena; Open Innovation samt medborgardialog kopplat till offentlig förvaltning. Det framkom i studien att faktorer som transparens, verktyg samt process är viktiga byggstenar i en Open Innovation-process. Utifrån studien har författarna tagit fram en metod som skall synliggöra hur de olika områdena samverkar med varandra och vilka verktyg som kan tillämpas i processen (se nedan). Författarna fann genom studien att hanteringen utav de idéer och förslag som hämtas från Open Innovation-processer är den viktigaste delen i processen. Utan en bra hantering utav förslagen tappar Open Innovation-processen sitt värde och förtroendet för förhållningssättet tappas.

    Lättillgänglig bostadsinformation på webben: En undersökning om hur lättillgänglig bostadsinformation för webben skrivs utan att viktig information försvinner.2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This is a thesis in information design with the emphasis on textual design. The purpose of this assignment is to investigate how to best write residential information for the web, which is accessible, without having to delete any important information. The goal is to create accessible texts with residential information, which can replace the original texts in a suitable way. Bostads AB Mimer’s (a land lord company) residential information has been analysed and investigated through a readability analysis, an interview and a questionnaire. The interview was held with Mimer’s head of communications and the purpose was to find out what Mimer wants to convey with their website and too whom. The study shows that the information on Mimer’s website has to be improved. The texts address the reader as you and themselves as we or us but not in a consequent way. Some entities are not explained enough and information directed too the residents and too those who are searching for an apartment, is mixed.

    Kommunikation & Utveckling inom proAros2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Problem:

    proAros har en idébank som är framarbetad av utvecklingsenheten för att främja idégenerering och nytänkande inom organisationen. Problemet är att idébanken inte används av de anställda. Hemsidan har blivit marknadsförd, men ändå verkar ingen använda sidan för att lämna sina idéer. Under studien framkommer det att många av de anställda inte vet om idébankens existens och att en bristande kommunikation råder inom hela organisationen.

    Syfte:

    Syftet med denna uppsats är att få svar på frågan varför idébanken inte används av de anställda inom proAros samt hur man kan lösa de kommunikativa hinder som uppstår vid informationsspridning inom organisationen.

    Metod:

    De metoder som används i denna uppsats är dels kvalitativa intervjuer men även kvantitativa enkätundersökningar bland anställda inom proAros. Blandningen av djupgående intervjuer och enkäter har sedan lett till slutresultatet. Vi har även använt oss av benchmarking, då vi besökt en annan organisation och där intervjuat en person, för att sedan jämföra deras system med proAros eget.

    Slutsats:

    proAros intranät är en databas som ska användas och vara tillgänglig för alla anställda inom proAros organisation, även idébanken ligger i anslutning till intranätet och nås via intranätets förstasida. Vår studie har visat att alla anställda inte har tillgång till intranätet samt att både intranätet och idébanken trots sin enkelhet kan vara svåra att manövrera. De anställda inom organisationen har heller inget behov av att använda sig av intranätet eller idébanken i sitt dagliga arbete. Vår slutsats är att för att få ett fungerande intranät och en fungerande idébank måste ett behov skapas hos de anställda för att i sitt vardagliga arbete besöka både intranätet och idébanken.

    Slutsatsen i praktiken:

    proAros ledare kan använda sig av de slutsatser som framkommit i uppsatsen för att förbättra och utveckla idébanken samt kommunikationen i organisationen.

    Kåpning till brandspaningsrobot FUMO 32013Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Detta projekt har utförts på en 10 veckors period och ligger på C-nivå (15högskolepoäng). Projektet gick ut på att ta fram ett kåpningsförslag för FUMO 3. Under denna period har de första 6 veckorna bestått av konceptframtagning och bearbetning av koncept, och de sista 4 av själva prototypframtagningen. Metoderna som använts för idégenerering och konceptframtagning har varit diverse produktutvecklingsverktyg. Då många ändringar och korrigeringar gjordes framför allt gällande basplatta, IP-lådor och externa enheter ganska sent in i projektet kunde gruppen inte fastställa ett konceptförslag förrän närmare slutet av arbetet med detta projekt. Prototypframtagningsprocessen utfördes genom bockning med maskin och för hands samt hopsättning genom popnitning. Mallar för utklippta plåtbitar togs fram genom CAD-ritningar som sedan ritadesut på pappskivor, som sedan provades på roboten i förväg. Då arbetet med prototypframtagningen gjordes i största mån för hand så lämnade gruppen utrymme för felpassningar som kunde uppstå på grund av felklippta plåtar, felaktiga bockningskanter och radier, skissnoggrannhet och annat orsakat av den mänskliga faktorn. Som slutsats ser vi oss ändå nöjda med att ha uppflyllt kraven under den tid som var utsatt.

    Undertexter för döva – Är de tillräckliga?: En studie om hur dynamisk textning kan var en fördel för de döva och dem med nedsatt hörsel.2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study is to find out if the deaf and hard of hearing community is in need of dynamic subtitles. Subtitles today are quite flat and seldom creative or expressive. Therefore a survey was formed to ask the deaf and hard of hearing community, their opinion on the matter. During the survey the participants were asked a number of questions concerning the matter. The questions composed of polls and areas where they could answer openly. At first the participants seemed to agree with the planned changes.

    The idea of this study came to me while I was creating a movie of my own. In the interest of conveying fast expressive comedy, rapid dynamic verbatim subtitles were formed in order to deliver the jokes and puns right on cue.

    Contrary to research and my own predictions, the deaf and hard of hearing community did not however favor that sort of dynamic verbatim subtitles. The pace was too fast and they didn't have time to read it. Even though former research have proved verbatim subtitles to be preferred throughout the community.

    "Gneta på...": Hur bör en politiskt styrd organisation agera för att inte påverkas av förändrade förutsättningar? 2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    It’s of great importance to implant innovation in organisations that act in an influenced and changeable environment. An organisation that’s affected by for example political decisions has a bigger challenge facing this. We also see that organisations within the service sector and mainly services that occur close to people have a more difficult task when it comes to the subject innovation. There is a limit in efficiency and development within organisations who acts in this area. Because the world always changes we think that organisations always need to face this to be able to deliver, and then it’s important that service companies are aware of the importance of innovation. Innovation within organising need not mean a whole new way of organising, but it can point out knowledge and its flow in the company. Even new ways of thinking who permeates an organisation can be the start of implanting a more innovative environment. We believe that a more proactive action can gain organisations development and efficiency. By this we mean that organisations can work more with their visions of the future and work more active with predicting the future and what it can offer. This can in turn gain implanting of innovation in companies.

    Man får vad man betalar för: Ett arbete i hur visuell information bör matcha ett varumärkes budskap2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This project has been done in cooperation with Etteplan. Etteplan has requested a user manual that sends a specific message: premium.In this project, attention has been focused on the visual design of a user manual and its importance to the brand. Brand theory, messages, gesture theories, pop out effects, information structure, paper quality and technical illustration have been studied to investigate how this can be designed to reach the premium feeling. In order to gain empirical data, interviews and world-wide analysis have been used. From the results of the world-wide analysis, the work has been able to systematically analyze how other actors visualize their user user manuals. Furthermore, the work, based on the results of theory and empirical data, has produced prototypes. These prototypes have been evaluated and developed and presented in the draft proposal.Creating something that is experienced as a premium is a challenge. It is not possible to point out where exactly the premium feeling comes from. It is a sum of all signals that a brand sends to the buyer. Everything from customer service, quality, price, staffing, visual profile, environmental profile and, for example, an instruction manual. In my role as information designer, my ambition has been to, create new guidelines for how a premium quality manual should be visualized.

    On the Feasibility of Low Cost Computer Vision: Building and Testing SimpleEye2014Independent thesis Basic level (degree of Bachelor), 180 HE creditsStudent thesis
    Abstract [en]

    This thesis explores a novel approach to the computer vision eld in the form of lowcost computer vision intended for industrial use. The system proposed in this thesis, calledSimpleEye, is implemented and tested against an existing system. Dierent approachesto object detection and data extraction from a scene, as well as common applications ofcomputer vision in the industry, are examined. Three algorithms are implemented, aimedat dierent industrial applications. These are two types of object recognition, using CannyEdge detection and connected-component labeling, as well as barcode scanning. The tests,each targeting one of the implemented approaches, show promising results for low costcomputer vision. While the system is expectedly lacking in speed, it has no diculties inachieving good result in applications which are not highly time critical. SimpleEye yieldedaccuracy and precision comparable to commercial systems, with parts costing approximately100 USD. The tests show that the system is able to function in several computer visionapplications used today, including visual servoing, blob detection, blob tracking, and barcodescanning.

    Collaborative distributed sun-tracking control system for building integration with minimal plant area and maximum energy-conversion efficiency2015In: International Journal of Electrical Power & Energy Systems, ISSN 0142-0615, E-ISSN 1879-3517, Vol. 70, p. 52-60Article in journal (Refereed)
    Abstract [en]

    This paper presents a collaborative distributed sun-tracking control system for a novel Fixed Mirror Solar Concentrator (FMSC) structure, which increases the energy-conversion efficiency of the FMSC and reduces the space between solar collectors units, a positive aspect for in-building integration. The improved FMSC uses solar concentration collectors suited for mid-range thermal applications (90-200 °C) and is designed for easy installation in buildings because of its relatively small extension. The proposed solar orientation system (ORSYS) relies on a two-step algorithm to increase the energy captured by the receiver, which provides tolerance to common logical and mechanical errors in the estimation of the receiver position. ORSYS is implemented as a CAN-based distributed system, extended with web-interface features for supervision and configuration of the overall system. ORSYS also includes a coordination algorithm that allows adjacent collectors to share the physical space between them, thus reducing the total plant area. Experimental evaluation has been performed using an industrial-scale solar collector prototype, showing its feasibility and efficiency in terms of energy conversion in real environments.

    Hangar of the future - digital scanning & analysis2017Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This final thesis is made by a student at Mälardalens högskola in Västerås from the academy of Innovation, Design and Engineering. This report examines the possibility of upgrading and modernizing current aircraft maintenance hangars by using the latest technologies.

     

    Aircraft maintenance is essential to keep aircraft’s continuing airworthiness, and making sure it’s always declared fit for flight. But the maintenance procedures in hangars today can be seen as a bit old-fashioned. This report is therefore aiming to explore the possibilities of building the hangar of the future, where the latest technologies is used for an easier, more accurate and faster maintenance. A big problem that this project could solve in case that it could be a reality is damage assessment. In flight industry is it a bit tricky to assess a damage that had happened to an aircraft with the current methods that are used in today’s maintenance hangars. Taking measures for damages isn’t easy, and it’s even harder to look into the Structure Repair Manual (SRM) in theory and follow it in reality to assess the damage. It is something that technicians and engineers suffer from, because of the big responsibility that it withholds.

     

    In the process of writing this thesis, and with the help of literature studies, an interview with the SAS engineer Anders Dalén, researches about the subject and the term of HOF at other companies the purpose of this thesis was reached. Which is exploring if HOF can be a reality in the near future. As for the technology of the project, it could be explained as a process or a chain that contains some steps. The idea is that an aircraft would roll into the hangar and get scanned by a stationary 3D scanner that is placed in the top of the hangar entrance. The data that the scanner later sends into a computer system gets processed by two or more programs in order to detect possible damage. If damage is found, then it would get measured with a portable 3D scanner. The analyzing programs would process its data and give an assessment on the damage, and also suggestions for reparations.

     

    The conclusion for this thesis is that it is, in theory, possible that “Hangar of the future” can be a reality in the future. Because the technologies that is required for it do exist in our time, though they exist in other forms/ branches.

    Intensity normalization of sidescan sonar imagery2016In: 2016 6th International Conference on Image Processing Theory, Tools and Applications, IPTA 2016, 2016, article id 7820967Conference paper (Refereed)
    Abstract [en]

    Sonar imaging is currently the exemplary choice used in underwater imaging. However, since sound signals are absorbed by water, an image acquired by a sonar will have gradient illumination; thus, underwater maps will be difficult to process. In this work, we investigated this phenomenon with the objective to propose methods to normalize the images with regard to illumination. We propose to use MIxed exponential Regression Analysis (MIRA) estimated from each image that requires normalization. Two sidescan sonars have been used to capture the seabed in Lake Vattern in Sweden in two opposite directions west-east and east-west; hence, the task is extremely difficult due to differences in the acoustic shadows. Using the structural similarity index, we performed similarity analyses between corresponding regions extracted from the sonar images. Results showed that MIRA has superior normalization performance. This work has been carried out as part of the SWARMs project (http://www.swarms.eu/).

    Algorithms for the Detection of First Bottom Returns and Objects in the Water Column in Side-Scan Sonar Images2017In: OCEANS '17 A Vision for our Marine Future OCEANS '17, Aberdeen, United Kingdom, 2017Conference paper (Refereed)
    Abstract [en]

    Underwater imaging has become an active research area in recent years as an effect of increased interest in underwater environments and is getting potential impact on the world economy, in what is called blue growth. Since sound propagates larger distances than electromagnetic waves underwater, sonar is typically used for underwater imaging. One interesting sonar image setting is comprised of using two parts (left and right) and is usually referred to as sidescan sonar. The image resulted from sidescan sonars, which is called waterfall image, usually has to distinctive parts, the water column and the image seabed. Therefore, the edge separating these two parts, which is called the first bottom return, is the real distance between the sonar and the seabed bottom (which is equivalent to sensor primary altitude). The sensory primary altitude can be measured if the imaging sonar is complemented by interferometric sonar, however, simple sonar systems have no way to measure the first bottom returns other than signal processing techniques. In this work, we propose two methods to detect the first bottom returns; the first is based on smoothing cubic spline regression and the second is based on a moving average filter to detect signal variations. The results of both methods are compared to the sensor primary altitude and have been successful in 22 images out of 25.

    Battery Connector - Examensarbete, Produktutveckling - konstruktion2013Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Examensarbetet är utfört inom produktutveckling – konstruktion och omfattar 15 högskolepoäng. Arbetet utfördes på halvtid under perioden januari – juni 2013. Examensarbetet utfördes för       OJOP Sweden AB i Eskilstuna av en student på Mälardalens Högskola. Examensarbetet startades den 6/1 – 2013 vid ett uppstartsmöte då uppdraget togs emot av OJOP Sweden AB´s ägare Anders Larsson. Uppdraget var att konstruera om eller konstruera en produkt med samma huvudegenskaper som företagets batterikontakt QuickPower. Detta för att reducera tillverkningskostnaderna som upplevdes för höga från företagets sida. Definitionen av problemet gjordes genom att undersöka den befintliga produkten och dess konkurrenter men också andra föremål som fäster på olika sätt. Undersökningarna resulterade i kunskap om hur problemet tidigare lösts och gav inspiration till en mängd idéer som bearbetades mentalt vilket ledde till skisser.  De olika skisserna sågs redan från början som potentiella koncept och redovisades för OJOP Sweden AB som fick utrymme att ge respons på koncepten. Ett koncept som innan redovisningen visat sig vara det bästa i både Pugh´s matris och QFD valdes gemensamt ut och fortsattes med. Det gjordes en enkel prototyp av det framtagna konceptet vilket bevisade en mycket bra funktionsduglighet. Med detta noterat och testat gjordes CAD-modeller som utgick ifrån prototypens dimensioner. Den slutgiltiga konstruktionen består av 6 (gånger två) komponenter, en huvudkomponent (spiralfäste), en kabelplatta, två plastkåpor och två skruvar. Dessa bearbetas på olika sätt och monteras samman för att vara redo att användas när kunden plockar dessa ur förpackningen. I jämförelse med den nuvarande produkten QuickPower håller sig resultatet på en nivå som matchar QP. En nackdel är att den inte fäster lika hårt som QP men resultatets enkla användning och resursbesparing höjer produkten.

    Automatic Generation of Timing Models for Timing Analysis of High-Level Code2011In: 19th International Conference on Real-Time and Network Systems (RTNS2011), 2011Conference paper (Refereed)
    Abstract [en]

    Traditional timing analysis is applied only in the late stages of embedded system software development, when the hardware is available and the code is compiled and linked. However, preliminary timing estimates are often needed already in early stages of system development, both for hard and soft real-time systems. If the hardware is not yet fully accessible, or the code is not yet ready to compile or link, then the timing estimation must be done for the source code rather than for the binary. This paper describes how source-level timing models can be derived automatically for given combinations of hardware architecture and compiler. The models are identified from measured execution times for a set of synthetic "training programs" compiled for the hardware platform in question. The models can be used to derive source-level WCET estimates, as well as for estimating the execution times for single program runs. Our experiments indicate that the models can predict the execution times of the final, compiled code with a deviation up to 20%.
