Increased efficiency and effectiveness in the product development process can be expected to result from extending the product development process to inciude the concurrent development of product and packaging. In this paper, the findings from three surveys performed in the Swedish mechanical, pharmaceutical and food industries by Bramklev, Bjärnemo and Jönson (2001 and 2003) are complemented wit
Phasor measurement signals are used as only input to a wide-area power system stabilizer to increase interarea mode damping of the Icelandic system. Modal analysis and time simulations of a detailed model show that frequency difference as PSS input gives a damping improvement that is robust to drastic changes in system topology. Field data from phasor measurement units indicate high signal quality
Making a web browser haptically accessible, makes it possible also for visually impaired persons to access graphical properties such as the layout of a web browser. With haptic interaction, it will also be possible to access 3D objects (VRML or X3D fil
Popular Abstract in English This thesis presents studies on moderately halophilic bacteria belonging to the family Halomonadaceae that accumulate polyhydroxybutyrate (PHB) in high amounts when grown under conditions of nitrogen limitation. PHB is the simplest homopolymer belonging to the class of polyhydroxyalkanoates (PHAs), biopolyesters that can biodegraded to carbon dioxide and water in the enThis thesis presents studies on moderately halophilic bacteria belonging to the family Halomonadaceae that accumulate polyhydroxybutyrate (PHB) in high amounts when grown under conditions of nitrogen limitation. PHB is the simplest homopolymer belonging to the class of polyhydroxyalkanoates (PHAs), the biopolyesters that can biodegraded in the environment to carbon dioxide and water and are hence
This thesis studies the efforts made by society to achieve more efficient energy use in order to better utilise resources and lessen the stress on the environment. Despite the value to society promised by more efficient energy use, too few attempts are made at realising this value. One instrument available to governments in their efforts to stimulate efficiency schemes, is to encourage energy comp
This key note paper discusses lesbian and gay studies, feminist theory, queer theory and the political struggle.
Two different approaches for developing virtual environments (VE) for brain injury rehabilitation are described and discussed. The two VEs are built with the VR software World Up in the form of virtual vending and automatic service machines. The result from the first approach is a virtual cash dispenser that has been tested on five patients with brain injury. Improving the VE according to the test
Longitudinal field inductors are frequently used in the industry for heating of flat objects. This paper aims to illustrate the current paths for the inductor design as a function of workpiece geometry using 3d FEA simulations. The results show how different parameters affect the heating pattern, creating guidelines for the optimal design depending on the requirements and applications. The simulat
