One significant environmental impact from assembly operations includes packaging material use and subsequent waste generation. Although current practice involves reduction of unnecessary materials handling, there is potential to adapt packaging material in order to simultaneously improve the environmental performance and reduce cost in a “lean and green” mindset. Hence, with increased emphasis on
Feedback in server systems has during last years gained much interest in order to fulfill still increasing demands on performance and optimization regarding, for example, quality of service (QoS) requirements. In this paper we investigate a feedback–based prediction scheme for controlling a single server queue. This control structure has the benefit over other previously suggested control structur
This paper summarizes an experimental investigation on several innovative reinforcing techniques for the “Single Large Diameter Dowel Connection”, SLDDC in timber truss structures. Besides lateral reinforcing or prestressing, also steel plates glued on two sides of the glulam specimens were used as reinforcing measure. To study the efficiency of these techniques, 15 full-scale quasi-static tensile
Abstract in Undetermined Pollenallergiker kan få ett bättre liv om de får information om tillståndet i luften. Det är till och med deras medborgerliga rättighet, enligt EU-direktiv, att få det. Därmed kan de förebygga symptom och planera sina aktiviteter. Avsikten med vår rapport är att bidra till underlaget för sådan en information, och att belysa hur de allergiska symptomen varierar med miljöfak
Electrical machines used in EV/HEV traction applications are usually driven at speeds where field weakening operation is required. In this region, electrically magnetized machines are more easily operated than permanent magnet machines. This paper discusses the performance of an electrically magnetized synchronous machine where the field coils are placed in magnetically conducting end-plates attac

We performed high-resolution simulations of two stellar collisions relevant for stars in globular clusters. We considered one head-on collision and one off-axis collision between two 0.6-Msolar main-sequence stars. We show that a resolution of about 100000 particles is sufficient for most studies of the structure and evolution of blue stragglers. We demonstrate conclusively that collision products
In this dissertation, The Public Library and the Museum of Modern Art in Stockholm – A Study of Architectural Criticism in the Swedish Press, the textual genre of architectural criticism is discussed from different perspectives. The principal aim is to illuminate, through a close reading of a sample of articles, how professional critics discursively and rhetorically communicate their idea of archi
