    Interactive research for production and work development2008Conference paper (Refereed)
    Abstract [en]

    Interactive research performed as a collaborative approach in conjunction with organizations is considered a new and promising alternative to other research approaches. The purpose of this paper is to describe how interactive research could be used in the interaction between researchers and organizations when running projects to develop production systems and work performed in these systems. It also aims to identify advantages and disadvantages when applying interactive research. Two long term interactive research projects, organised in collaboration with the partnership of Helix Vinn Excellence Centre at Linköping University were performed and data were collected from documentation of interactive seminars, from notes and from interviews with key actors. Interactive research offers several advantages in comparison with traditional research approaches, foremost higher practitioner involvement and validation opportunities of the results. There are also several difficulties, foremost the need of extensive resources and competencies for the research. The overall experiences from participating practitioners were that they considered that the discussions had been useful, stimulating and interesting, and that the fast feedback from data collection was appreciated. One crucial issue is to what extent this interactive research approach may contribute to high quality research, or to what extent the pressure from the practitioners for actionable practical results will take over.

    Work environment at state-of-the-art recycling centres2008Conference paper (Refereed)
    Abstract [en]

    Recycling centres have a key role in the recycling branch. It is important that the waste is disposed in the right container to avoid pollution of the fraction. The layout of the facilities as well as the employees at the recycling centres are important to secure good sorting quality. There is a high frequency of injuries among the employees. The aim of the present study is to compare the work environment at the two new built recycling centres with improved layout, with other recycling centres in Sweden. The study population comprised all employees at 42 older recycling centres, totally 122 persons and 300 visitors, and 8 employees, and 41 visitors at two new built recycling centres. Questionnaires were used for data collection. More visitors at the two new recycling centres assessed it easy to find the right container for their waste and high quality of service compared to the first study. The employees at the new recycling centres assessed their physical tiredness lower, compared to employees at the older recycling centres. The employees had the highest risk for an injury was when picking up wrongly sorted waste and when packing manually in cages. There is still some need for improvement, especially concerning lifting and transfer equipment at the new recycling centres

    3D-correlation-averaging for membrane-protein-crystals2008In: EMC 2008 14th European Microscopy Congress, 2008, p. 55-56Conference paper (Refereed)
    Abstract [en]

    Few 2-dimensional protein crystals can be used to determine high-resolution structures, whereas most electron crystallography projects remain at a resolution around 10 Ångström. This might be partly due to lack of flatness of many two-dimensional crystals [1]. We have investigated this problem and suggest single particle projection matching (3D-correlation averaging) of locally averaged unit cells to improve the quality of three-dimensional maps. Theoretical considerations and tests on simulated data demonstrate the feasibility of this refinement method [2].

    Inclusive Design Instead of Assistive Technology in Housing2008In: Proceedings of the 4th Cambridge Workshop on Universal Access and Assistive Technology / [ed] Clarkson, PJ et al ( Eds), 2008, p. 107-112Conference paper (Refereed)
    Abstract [en]

    Abstract

    The growing number of inhabitants in need of care and rehabilitation is a common problem in most industrialised countries. More medical conditions can be treated, but often at increasing costs. Care and housing are often interlinked and more interest is being paid to the possibility of offering care to elderly in their own homes. It is not only technology and care that matter; an equally important issue is how well the dwellings are adapted to care, both from a spatial perspective and in supporting new technology. It is a relatively widespread opinion that ICT (Information and Communication Technology) has the potential to support the resources of the caring professions without reducing the quality of the care itself. The complexity of relatively simple technology in use with Home Care and Telemedicine is often underestimated; there are many obstacles.

    In order to conduct applied research about assistive technologies and ergonomics when an apartment is also a work place for professionals giving care and assistance to people in their own home, the University has decided to construct a full scale laboratory in the form of two complete, self-contained and fully equipped apartments. The laboratory will be used to study and develop new technologies and work processes in the home. In different zones such as the kitchen, the bedroom, the living room, the hallway, the cloakroom and the bathroom, there will be different research projects implemented. Subjects and professional care staff will be invited to participate in the studies.

     In different zones there will be different research project implemented:

     In the bathroom we will develop design for assistive work respectively design for independent intimate hygiene. The Japanese toilet style which include cleaning and drying system will be tested.

    In the bedroom we are planning a lightning system for light close to the floor as a guide when one goes up in the night time.

    In the kitchen we will investigate how to create good lighting and storage conditions while preventing old people from falling when trying to replace a bulb or climb to high cupboards.

    In the kitchen new approaches to deal with fire risk and the stove and oven will be studied.

    In one project we have planned to study how the access to the apartment can be dealt with in ways that support the elderly person with memory problems and the healthcare provider.

     

    By using a full scale laboratory where tenants and caring professionals as well as facilities managers are included, all aspects of the apartment can be scrutinized. Instead of assistive technologies the goal is to develop and test solutions based on the concept of inclusive design.

    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.

    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, p. 99-114Conference 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.
