    E-Learning for empowering the rural people in Bangladesh opportunities and challenges2013In: The Second International Conference on E-Learning and E-Technologies in Education (ICEEE2013), 2013, 323-328 p.Conference paper (Refereed)
    Abstract [en]

    AbstractInadequate educational resources,insufficient and unqualified teachers and health care providers,and lack of community involvement, are some of the causes that contribute to the oor state of education and health in rural Bangladesh. This is although, it is well known that,access to quality education and scientific knowledge is essential for creating economic rowth and sustainable human development, including poverty alleviation and improvement of human health. In all countries and in the developing countries in particular, there is a need to mploy Information and Communication Technology, ICT to gain global access to learning. ICT an address issues of educational equity, social exclusion and can deliver a more effective and ccessible educational opportunities. It can also reduce cost of reaching and educating many ural students who are deprived of creative education due to lack of qualified teaching force.

    In Bangladesh, the education curriculum has been modernized to meet an international standard. For various reasons, qualified teachers are not keen to move to rural areas. The same is true in areas of health sectors where qualified medical doctors are not willing to move to rural areas. Therefore, we find enormous potentials for contribution of e-Learning and e-Health in empowering the rural educators as well as health care providers. A pilot project to test the potentials of e-Learning is implemented at a village Nohata in Magura district in Bangladesh (www.nuhat.org). Started in 2006, it has been using ICT tools to communicate, learn, and access international quality educational content. International quality teachers have been conducting teaching using videoconference system. Various relevant e-Learning aids have been developed to meet the local needs and conditions, you tube programmes covering different topics are carefully selected to meet the appropriate requirement of different target groups. The links are downloaded so that the students, the teachers, health workers, patients can follow the links off line, as many times as they want and discuss among themselves. The ICT tools are also being used to improve access to health care; enhance the quality of service delivery; improve the effectiveness of public health and primary care interventions; improve the shortage of health professionals through collaboration and training. ICT tools are offering solutions for emergency medical assistance, long-distance consultation, supervision quality assurance, and education and training for healthcare professionals and providers. The main challenges are to empower the rural people through creating locally relevant content for improving proficiency in English language, Mathematics, Science and Health care application and services considering the sociocultural factors, to achieve health, education and economic development. Through careful selection and creation of relevant e-Learning materials, we intend to develop the rural community using the potential of rural people and adopting participatory approaches for building  knowledge, skills and capacity.

    Keywords: e-learning in developing countries, rural empowerment, relevant content, e-health, rural health quality improvement

    Energy savings and thermal comfort with ventilation radiators: a dynamic heating and ventilation system2007In: Proceedings of Clima 2007 WellBeing Indoors, 2007Conference paper (Other academic)
    Abstract [en]

    Studies indicate that a high ventilation rate with fresh air supply directly from outdoors gives better thermal comfort conditions, less SBS (Sick Building Syndrome) symptoms and increased work productivity. The drawbacks with a high ventilation rate in natural or exhaust ventilated buildings are normally increased energy use for heating and cold air draught. Such problems may be minimized with ventilation radiators, radiators where cold ventilation air is brought directly from outdoors through a wall channel into the radiator where it is heated before entering the room.

    This paper discusses advantages with ventilation radiators in comparison to those of traditional heating systems. Focus has been on energy aspects and thermal comfort. The main conclusions are that ventilation radiators may give a stable and uniform thermal indoor climate. The high thermal gradient between cold ventilation air and the radiator surface inside the ventilation channel also makes the ventilation radiator more efficient than other systems. A method to vary indoor climate on a daily basis according to where people stay is proposed for additional energy savings with ventilation radiators. The deductions were based on results from CFD simulations in a well validated office model.

    Summertime cooling with ventilation radiators2007In: IAQVEC 2007 Proceedings - 6th International Conference on Indoor Air Quality, Ventilation and Energy Conservation in Buildings: Sustainable Built Environment, 2007, 533-538 p.Conference paper (Refereed)
    Abstract [en]

    Ventilation radiators, heat emitters where cold ventilation air is brought directly from outdoors into the room via heated radiator surfaces, are becoming more and more common in Scandinavia. Because these systems combine both heating and ventilation several interesting aspects arise that may be used to save energy and improve indoor thermal climate. The heating aspects in wintertime have been discussed in previous papers from KTH STH. This study investigates whether ventilation radiators may be used for cooling in summertime. Results from the study show that condensation of water is the main problem to tackle when ventilation radiators are used for cooling purposes. It is difficult to avoid condensation, especially inside the ventilation channel where incoming ventilation air comes into contact with chilled radiator surfaces. The problem increases with increased temperature difference between radiator surface and ventilation air. This is why ventilation radiators seem unsuitable for cooling in summertime without risking condensation of water. However, if condensation of water is allowed in the ventilation channel only, ventilation radiators may be functional for cooling. The trick is to find a way to drain water from the ventilation channel to avoid hygiene problems.

    NanoXCT: Development of a laboratory nano-CT system2014In: Proceedings of SPIE - The International Society for Optical Engineering, 2014Conference paper (Refereed)
    Abstract [en]

    The NanoXCT project aims at developing a laboratory nano-CT system for non-destructive testing applications in the micro- and nano-technology sector. The system concept omits the use of X-ray optics, to be able to provide up to 1 mm FOV (at 285 nm voxel size) and down to 50 nm voxel size (at 0.175 mm FOV) while preserving the flexibility of state-of-the-art micro-CT systems. Within the project a suitable X-ray source, detector and manipulation system are being developed. To cover the demand for elemental analysis, the project will additionally include X-ray spectroscopic techniques. These will be reported elsewhere while this paper is focused on the imaging part of the project. We introduce the system concept including design goals and constraints, and the individual components. We present the current state of the prototype development including first results.

    On the applicability of trusted computing in distributed authorization using Web services2008Conference paper (Refereed)
    Abstract [en]

    Distributed authorization provides the ability to control access to resources spread over the Internet. Typical authorization systems consider a range of security information like user identities, role identities or even temporal, spatial and contextual information associated with the access requestor. However, the ability to include computing platform related information has been quite limited due to constraints in identification and validation of platforms when distributed. Trusted computing is an exciting technology that can provide new ways to bridge this gap. In this paper, we provide the first steps necessary to achieving distributed authorization using trusted computing platforms. We introduce the notion of a Property Manifest that can be used in the specification of authorization policies. We provide an overview of our authorization architecture, its components and functions. We then illustrate the applicability of our system by implementing it in a Web service oriented architecture.

    Fostering communication between the elderly and the youth with social games2015In: Pacific Asia Conference on Information Systems, PACIS 2015 - Proceedings, 2015Conference paper (Refereed)
    Abstract [en]

    In today's aging societies, elderly people often have difficulties to find people to communicate with. To address this loneliness of the elderly, it has been suggested to create more opportunities for children and elderly people to engage in various shared activities together. In this ongoing research, we investigate that social offline games can facilitate communication between the generations by creating a mutually enjoyable environment where elderly and young persons can interact with each other. A longitudinal approach is used to investigate whether intergenerational communication actually is enhanced by utilizing social offline games as the medium. Prior research has been conducted in related topics, such as the perceptions of the young and elderly participants towards each other in a game setting, as well as the impacts to communication behaviours among players of the same generation. We aim to build a model that connects game enjoyment, intergenerational perceptions and communication, and ultimately contribute to improving the well-being and relieving the loneliness experienced by many elderly people.

    The Soft Extra Muscle System for Improving the Grasping Capability in Neurological Rehabilitation2012In: 2012 IEEE-EMBS Conference on Biomedical Engineering and Sciences, IECBES 2012, New York: IEEE , 2012, 412-417 p.Conference paper (Refereed)
    Abstract [en]

    This paper introduces the SEM Glove (Soft Extra Muscle Glove), a comfortable aid which automatically improves the grasping capability of a human independently of the particular task being performed. The technical solution partly mimics a biological solution and at the same time functions in symbiosis with the biological system. The technical invention is also applicable to other parts or regions of the human body that might need supporting forces or torques. A key feature is that a controlling and strengthening effect is achieved without the need for an external mechanical structure in the form of an exoskeleton. The paper includes a description of the physical design, the contents and the system design.

    Algorithm Comparison for Cardiac Image Fusion of Coronary Computed Tomography Angiography and 3D Echocardiography2015In: 2015 IEEE INTERNATIONAL ULTRASONICS SYMPOSIUM (IUS), IEEE , 2015Conference paper (Refereed)
    Abstract [en]

    Treatment decision for coronary artery disease (CAD) is based on both morphological and functional information. Image fusion of coronary computed tomography angiography (CCTA) and three-dimensional echocardiography (3DE) could combine morphology and function into a single image to facilitate diagnosis. Three semi-automatic feature-based algorithms for CCTA/3DE registration were implemented and applied on CAD patients. Algorithms were verified and compared using landmarks manually identified by a cardiologist. All algorithms were found feasible for CCTA/3DE fusion.

    In flight SEU tests on the European SMART-1 spacecraft2005In: Proceedings of the European Conference on Radiation and its Effects on Components and Systems, RADECS, 2005, PH11-PH13 p.Conference paper (Refereed)
    Abstract [en]

    The SMART-I satellite launched by the European Space Agency has traveled to an orbit around the Moon driven by its own ion engine. Because of the characteristics of the ion engine mission required many revolutions to reach the Moon and the time to pass through the radiation belts around the Earth was significant. The spacecraft is exposed to solar protons throughout its mission. In advance the flight in-beam test data was collected to asses the radiation hardness properties of an SRAM, one of the components of the system unit of the satellite. Single Event Upset data is available for this component and Solar Proton Flux was measured by the GOES satellite in Geosynchronous orbit. The aim of this work is to compare the predictions of the in-beam tests and the effects of the in space irradiation of SRAM circuits on board.

    Abstract [en]

    Research in innovation has created much knowledge to apply concerning tools, methods and processes. However, the challenge of allowing "space", time and competence for innovation capability development is sparsely reported. The purpose of this research is to identify how organizational and behavioral factors are affecting product innovation capability and its development in organizations. The research sets out to explore and elaborate on the research question: How can product innovation capability among organizations and individuals be improved by identifying and changing organizational factors? The individual and organizational factors need to be taken in relation to the product innovation. Theories of innovation capability, innovation and learning, innovation and creative climate are used as a basis for this research. Interviews and a creative climate questionnaire have been used for empirical input in five med-tech companies. The qualitative result elicits six factors that influence the innovation capability and its development in organizations; brings out the two most important factors from the survey and elaborate a cross analyses from the qualitative and quantitative input.

    Investigating interference between LoRa and IEEE 802.15.4g networks2017In: Proc. 13th International Conference on Wireless and Mobile Computing, Networking and Communications, IEEE Computer Society, 2017Conference paper (Refereed)
    Abstract [en]

    The rapid growth of new radio technologies for Smart City/Building/Home applications means that models of cross-technology interference are needed to inform the development of higher layer protocols and applications. We systematically investigate interference interactions between LoRa and IEEE 802.15.4g networks. Our results show that LoRa can obtain high packet reception rates, even in presence of strong IEEE 802.15.4g interference. IEEE 802.15.4g is also shown to have some resilience to LoRa interference. Both effects are highly dependent on the LoRa radio's spreading factor and bandwidth configuration, as well as on the channelization. The results are shown to arise from the interaction between the two radios' modulation schemes. The data have implications for the design and analysis of protocols for both radio technologies.

    Wireless sensor networks have today emerged as a feasible infrastructure for healthcare applications. This paper addresses the non-trivial performance problems in contentionbased wireless networks. We present a method for admission control in contention-based networks, implemented as a component of a performance management system. The test results show that admission control can improve the predictability and level of performance in wireless sensor networks. The system can be used as a tool for dimensioning and configuration as well as for real-time admission control. The often unpredictable dynamics in contention-based access networks means that continuous performance control is needed to maintain a desired quality of service.

    Facilitating the Learning Environment: Initiatives within the PIEp Research School2009Conference paper (Refereed)
    Abstract [en]

    Research schools have become common phenomena in the academic world. However, we find lack of studies investigating their influence and role in the academia. This study attempts to address this gap by describing how a specific research school has evolved into an effective learning environment for the enrolled PhD students. The Product Innovation Engineering program (PIEp) is currently the largest research initiative in Product Innovation in Sweden. The PIEp research school is a part of this program, with the aim to increase innovation capabilities in the Swedish industries. Through an action-based research approach the authors, who are research school participants themselves, present the processes and the chain of events to offer knowledge transfer and to give insight into this special research environment. In this pursuit, the findings are presented in three different themes,1) the role of common interest groups, 2) common interest group activities, and c) a tiger team workshop. This paper holds major implications for other research schools and funding organizations.

    Image denoising with convolutional neural networks for percutaneous transluminal coronary angioplasty2018In: VipIMAGE 2017: Proceedings of the VI ECCOMAS Thematic Conference on Computational Vision and Medical Image Processing Porto, Portugal, October 18-20, 2017, Springer Netherlands, 2018, Vol. 27, 255-265 p.Conference paper (Refereed)
    Abstract [en]

    Percutaneous transluminal coronary angioplasty (PTCA) requires X-ray images employing high radiation dose with high concentration of contrast media, leading to the risk of radiation induced injury and nephropathy. These drawbacks can be reduced by using lower doses of X-rays and contrast media, with the disadvantage of noisier PTCA images. In this paper, convolutional neural networks were used in order to denoise low dose PTCA-like images, built by adding artificial noise to high dose images. MSE and SSIM based loss functions were tested and compared visually and quantitatively for different types and levels of noise. The results showed promising performance for denoising task.

    Mathematical human body models in side impacts- A validation study with particular emphasis on the torso and shoulder and their influence on head and neck motion2008In: Int. Res. Counc. Biomech. Inj. - Int. IRCOBI Conf. Biomech. Inj., Proc., 2008, 99-114 p.Conference paper (Refereed)
    Abstract [en]

    The ability of three mathematical human body models to predict previously published human responses in two different side impact loading configurations was evaluated using an objective rating method. In particular the kinematics of the shoulder, T1 and head were evaluated. The human body models evaluated were THUMS, HUMOS 2 and the GM model. The impact loading configurations used were pendulum impact tests and sled tests. In the pendulum configurations, the closest correlation to the published responses was shown by THUMS followed by the GM model. In the sled configuration, closest correlation to the published responses was shown by HUMOS 2 followed by THUMS. According to the objective rating method the published responses in the pendulum configuration were predicted by all human body models. The published responses in the sled configuration were predicted by HUMOS 2 and THUMS.

    Abstract [en]

    The rapid development of Intelligent Transport Systems has created new objectives and requirements for traffic simulation models. The development of visualization, procedural modeling, decision support requirements mean that simulation models need to satisfy different requirements. The chapter presents methods and tools to create distribute, integrated and interactive transport simulations, to enable the holistic exploration of complex transport systems, to test different strategies for monitoring and control and for training personnel. The integrated simulation is built leveraging gaming technologies, integrating commercial or off-the-shelf simulations using methods from distributed simulation and procedural modeling techniques.

    Hybrid, composable approach to simulations in healthcare operations and management2017In: Proceedings of the 2017 Winter Simulation Conference / [ed] W. K. V. Chan, A. D'Ambrogio, G. Zacharewicz, N. Mustafee, G. Wainer, and E. Page, ACM Digital Library, 2017Conference paper (Refereed)
    Abstract [en]

    Simulation has been used for modeling in healthcare for many decades. Ranging from the modeling of physiological processes to group dynamics to the modeling of strategic and system-wide models of healthcare provision, simulation promises to be an effective approach to analyze healthcare operations. Effective application of simulations in healthcare operations requires that simulation deal with wide variability and unpredictability in workflow processes, the complexity of healthcare organizations and enables the participation of human experts in the modeling and operations processes. In this paper, based on requirements drawn from a participatory simulation with healthcare practitioners, we define a hybrid, composable approach to healthcare simulations. Both the participatory simulation and the composable simulation are applied in the context of the New Karolinska Solna hospital in Sweden, a highly specialized new hospital. Results point to the need to accounting for variability in workflow processes and integration with existing IT infrastructure in hospitals.

    Abstract [en]

    Mainstream discourse in urban planning is in transition, due to shifts from a technical to a communicativeperspective, and increased scrutiny and criticism of models and simulations. The cognizance of complexityin urban systems is imposing limitations on modeling. The added benefits of today’s data and compu-tational power make simulations harder to validate and understand. Reconciling the movements towardsa communicative and exploratory approach as compared to a technical and predictive approach requiresnew methods for planning process and posits new requirements and functions for simulations. Based ondistributed simulation and gaming simulation, the paper presents a framework to support the exploration ofsimulated and realistic virtual worlds in a participatory fashion, enabling new approaches to urban planning.The development and evaluation of the framework casts simulations in a new perspective and explores thecontext of use of simulations in planning and design.

    Gaming, urban planning and transportation design process2015In: Lecture Notes in Geoinformation and Cartography, 2015, Vol. 213, 297-312 p.Conference paper (Refereed)
    Abstract [en]

    In today’s urban planning, two perspectives dominate the discourse: a technical-rational perspective and a communicative rational perspective. Bridging the dichotomy between the two perspectives and situating new planning support methods within the context of complexity theories leads to new structures for planning support systems. The implications of the inherent complex nature of planning when bridging these perspectives should be taken into account for new planning processes and support systems. The development of such methods requires an iterative cycle between methodological and technological aspects of tool development. The chapter presents a technical framework that enables the development of methods integrating both perspectives. The framework derives its requirements from the integration of the two perspectives, and is evaluated in the context of two design case studies in the cities of Stockholm and Paris. The development of the framework and method has implications for the design of tools in urban planning. The tools need to reflect the open nature of the complex systems they represent and operate in. Such methods also expand the boundaries of the design space, allowing for previously unknown configurations.

    Analytics on public transport delays with spatial big data2016In: Proceedings of the 5th ACM SIGSPATIAL International Workshop on Analytics for Big Geospatial Data, BigSpatial 2016, ACM Digital Library, 2016, 28-33 p.Conference paper (Refereed)
    Abstract [en]

    The increasing pervasiveness of location-aware technologies is leading to the rise of large, spatio-temporal datasets and to the opportunity of discovering usable knowledge about the behaviors of people and objects. Applied extensively in transportation, spatial big data and its analytics can deliver useful insights on a number of different issues such as congestion, delays, public transport reliability and so on. Predominantly studied for its use in operational management, spatial big data can be used to provide insight in strategic applications as well, from planning and design to evaluation and management. Such large scale, streaming spatial big data can be used in the improvement of public transport, for example the design of public transport networks and reliability. In this paper, we analyze GTFS data from the cities of Stockholm and Rome to gain insight on the sources and factors influencing public transport delays in the cities. The analysis is performed on a combination of GTFS data with data from other sources. The paper points to key issues in the analysis of real time data, driven by the contextual setting in the two cities. © 2016, Association for Computing Machinery, Inc. All rights reserved.

    100 GHz SOI gap waveguides2013In: 2013 Transducers and Eurosensors XXVII: The 17th International Conference on Solid-State Sensors, Actuators and Microsystems, TRANSDUCERS and EUROSENSORS 2013, 2013, 510-513 p.Conference paper (Refereed)
    Abstract [en]

    Two gap waveguide technologies, groove and ridge, are presented here for F-band applications. Three different groove gap waveguide devices and four different ridge gap waveguide devices have been fabricated. All of them were micromachined to achieve the feature size required for the frequency band and fabricated in a single process using SOI wafers. The two types provide a more robust coupling to standard waveguides and high frequency probes. Measurements for most of the devices are shown in this paper, showing robust measurements and good agreement with simulations. More measurements need to be done but the initial ones show the promise both in the manufacturing technique and the coupling.

    Rapid manufacturing of OSTE polymer RF-MEMS components2017In: Proceedings of the IEEE International Conference on Micro Electro Mechanical Systems (MEMS), IEEE, 2017, 901-904 p.Conference paper (Refereed)
    Abstract [en]

    This paper reports the first RF-MEMS component in OSTE polymer. Three OSTE-based ridge gap resonators were fabricated by direct, high aspect ratio, photostructuring. The OSTE polymer's good adhesion to gold makes it suitable for RF-MEMS applications. The OSTE ridge gap resonators differ in how they were coated with gold. The OSTE-based devices are compared to each other as well as to Si-based, SU8-based, and CNT-based devices of equal design. The OSTE-based process was performed outside the cleanroom, and with a fast fabrication process (∼1 h). The OSTE-based device performance is on par with that of the other alternatives in terms of frequency, attenuation, and Q-factor.
