Dagens och morgondagens LSS-boende : Rapport från en FoU-cirkel i Skåne
- 2008
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Denna rapport behandlar frågor som rör dagens och morgondagens boende för målgrupper inom LSS. Handläggare och chefer från åtta kommuner i Skåne som arbetar med dagens boende eller ansvarar för planering och utveckling av boendeformer har i en FoU-cirkel diskuterat problem och möjligheter inför framtiden. Deltagarna har identifierat och lyft viktiga frågeställningar att arbeta vidare med ute i kommunerna för att möta brukarnas behov och önskemål

A preliminary study of wireless body area networks
- 2008
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The purpose of this preliminary study is to introduce wireless body area networks (WBAN) to the reader but also to give an understanding of what possibilities and challenges there are when using short range wireless communication in this domain. Up to date, there is no standard specifically intended for low-power WBANs thus a developer is referred to use proprietary solutions which could be demanding to compare and choose. This study tries to provide the reader with the knowledge about important parameters in low-power sensor networks. Energy consumption is the really weak part of a wireless sensor network since the transceiver and other hardware equipment still drain batteries. For example the startup time for a transceiver that has been in power-down mode could consume as much as three times the energyas compared when sending the actual bits that invoked the transceiver in first place. The actual application must be the one driving the requirements on the communication. However, the application must be designed with for example the startup time in mind. A sensor network is a true cross-layer design problem where many different areas must meet such as hardware designers, application developers and communication people.

Robot assisted framing : A concept for securing geometry in flexible production
- 2008
-
Rapport (refereegranskat)abstract
- The paper describes a concept for securing the geometry in flexible production based on robot assisted framing. This uses the robot(s) as an active device during change-over between product variants and it is assumed that product variants can be produced in any mixed order. The case under study is cabs for trucks which in traditional production require large and heavy equipment which is above the payload of any robot. The idea within this study is to use carbon fibre composites in the fixtures in order to reduce the weight and through this make it possible to use the robots in assisting the framing process. The current work involves a generalization of the principle both considering the design of the fixtures with respect to issues such as materials properties and design principles, and design of the production system.

Mäns våld mot kvinnor i nära relationer – och barn som upplever våld : En forsknings- och kunskapsöversikt
- 2008
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This report presents a summary of Swedish research and knowledge concerning men’s violence against women in intimate relationships. It also discusses children’s experiences of this violence. Various theoretical perspectives on men’s violence are illustrated. A structural perspective on men’s violence is described using concepts like gender, power and normalization of violence. Some interactionist-based theories concerning assaulted women’s resistance are also discussed. The report further gives attention to research about children who have experienced violence against their mothers. Also discussed are particularly vulnerable groups of women (refugees, immigrants, elderly women and women with functional disability).Veronika Burcar is a university lecturer at the School of Social and Health Sciences, Halmstad University. Predominantly she is teaching sociology, social psychology and criminology. She also teaches diversity and culture at the Department of Teacher Education. In 2005 Burcar publicly defended her doctoral dissertation, “Talking about violence: young men's victim narratives”, at Lund University. In a newly published research report, commissioned by Landskrona city council, Burcar is studying safety work in Landskrona city. Her interests within research are mainly violence, victimhood, safety, social deviation, ethnicity and inclusion/exclusion.

Ny teknik för avisning av vindkraftsvingar
- 2008
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This is a pilot study to investigate icing on wings of wind power turbines. In this report we present and discuss various ways and means to either heat water droplets or melt ice when formed on the wings of wind turbines. The situation is different from icing on wings of airplanes in that (1) the wings of wind turbines spend all of their time in the atmosphere where the risk of icing is highest and (2) the speed of wing to air varies over the wing where it is constant for an airplane. The form of the wind turbine wings also varies from tip to centre, to compensate for the varying relative air speed.We have concentrated on icing conditions at temperatures -10°C – 0°C and droplet sizes of 1-10 μm. Icing occurs also at much lower temperatures, but this will probably be because of direct freezing of water vapour to ice. This is presently outside the scope of our pilot project report.We conclude thatThe form of the wing, especially on the contact area may be crucial to the icing problem.Also the nano-metric structure of the wing surface can probably be designed so that the water droplets have a minimized contact area to the wing.Our pilot investigation also suggests the following:Microwaves are much too inefficient to heat water or melt ice. Direct microwave devices should therefore not be developed. Indirect heating with microwaves is possible.Millimeter waves are sufficiently efficient, but the generation is most probably too inefficient to be of any practical use.Infrared waves are very efficient to heat water and melt ice and should be investigated.Heat conduction is also efficient and should be pursued. Using microwaves to heat the wing surface which then conduct heat to the water/ice is a very efficient and robust method.Our pre-study suggests that the solution to avoid icing or de-ice wings of wind turbines most probably is not one single technology. The form and surface structure of the wings play important role for icing conditions. Both variables have to be modified depending on the latitude and atmospheric climate. The surface structure also has to be designed to vary over the wing, both along and across to be optimized for the mean conditions at the site. In addition, heating of the impact area, or at least the possibility to heat this, may be important to avoid loss of energy output due to ice.Further research is required. We strongly suggest investigating the water droplet flow over the wing as function of the cross section form, and the contact with the wing surface as function of the surface structure (e.g. Lotus effect).The present report is the result of a pre-study project. We will now continue with a deeper project which will concentrate on the form and surface structure suggestions which results from our analysis and flow simulations.
