Requirements and Use of In-service Information in an Engineering Redesign Task: Case Studies from the Aerospace Industry

This paper describes the research stimulated by a fundamental shift that is occurring in the manufacture and marketing of aero engines for commercial and defence purposes, away from the selling of products to the provision of services. This research was undertaken in an aerospace company, which designs and manufactures aero engines and also offers contracts, under which it remains responsible for

Jerusalem mitt i byn. Det tidigmedeltida kyrkobyggandet ur rituellt perspektiv.

The stone churches of the early medieval period are commonly supposed to have been built at the instance of society’s upper echelon, the buildingsthemselves being seen as symbolic proclamations of the social hegemony of the class concerned. The present article seeks to broaden the perspective regarding both the prime movers of church building and their motives. The building of a church required th

Evidentiary assessment in refugee status determination and the EU qualification directive

Evidentiary assessment in asylum procedures is an area largely unregulated by international law. While the EU Qualification Directive does not purport to fill this lacuna, its Article 4 offers a norm that does touch on a number of central aspects of evidentiary assessment. This article provides a detailed analysis of this complex provision and its practical implications. Amongst others, the Direct

A generic hardware MAC for wireless personal area network platforms

This paper presents a generic hardware-MAC for systems designed based on high rate (IEEE 802.15.3) and low rate (IEEE 802.15.4)Wireless Personal Area Networks. functionality that are better run in hardware are moved over from the software part of the MAC layer. An easy to access memory like interface has been defined for data and control transfer between the software and hardware parts of theMAC l

Condon's model on optical rotatory power and causality - a scientific trifle

In this paper some of the consequences of the model for optical activity suggested by Condon are analyzed. The scattering problem is solved for a semiinfinite and a finite homogeneous slab, respectively. Specifically, the noncausal effects of this model are demonstrated. These effects are disturbingly large for many materials and the model has to be discarded as unphysical. The rotation of the pol
