Mobiltelefonen har gått igenom en enorm teknisk utveckling de senaste åren. För antennens del har det inneburit en rad förändringar och denna artikel försöker beskriva några av de nya utmaningar som antennspecialisterna idag ställs inför. Antennen är numera ofta inbyggd i telefonen och täcker fler band på högre frekvenser och som inbyggd har den betydligt sämre förutsättningar än tidigare att fung

Background: Current models of group development favor views assuming that groups move from relative irrationality and inefficiency to rationality and efficiency in defined sequential stages. Aims: To present (a) a project questioning the generality of the linear progressive models of group development, (b) an alternative model taking into account factors related to formation, time, boundary manag

The Nature of Science-based Controversies. The following points will be presented: 1. Political and epistemological reasons for studying science-based controversies. 2. Controversies as conflicts between rival professional groups and incommensurable systems of ideas. 3. Results and discoveries emanating from case studies of science-based controversies: four examples. 4. Towards a theory of sci

Resfria möten (RM) är en samlingsterm för möten på distans, i realtid med teknikens hjälp, innefattande telefon-, webb- och videokonferens. Denna rapport beskriver svenska och internationella erfarenheter av dessa mötesformer med fokus på effekter på resandet och utsläpp av klimatgaser. Framtidsprojektioner för resfria mötens effekter 2030 och 2050 görs också.

This paper discusses the possible advantages and disadvantages by using experimental methods in order to understand how music influences our understanding of film narratives. Can experimental and quantitative methods such as eye tracking, questionnaires, galvanic skin response, EEG (electroencephalogram) and fMRI (functional magnetic resonance imaging – a brain scan) give us insights into the sign

Purpose of this paper: Increasingly more companies need supply chains that satisfy individual needs and can adapt to a changing environment while simultaneously keeping costs down. Hence, flexible and integrated supply chains are needed. The purpose of this paper is to develop a conceptual research platform for studies of how companies can develop such solutions. Design/methodology/approach: A sys

Since ancient times, reeds have been used as a low-tech building material in several construction purposes. Reed is a natural building materials that possess many useful benefits in contemporary building practices. Reeds grow around lakes, swamps and other water canals and have no environmental impact if dismantled after construction as they are biodegradable. Reeds are also easy to cut and handle

We propose a simple optimal a posteriori probability (APP) symbol decoding algorithm for linear block codes, which requires one forward recursion in a trellis.

In a multi-storey residential housing project comprising of four 8-storey timber buildings, the bottom storeybeing designed with concrete and storeys 2-8 in timber, the vertical relative displacement, the temperature and the relativehumidity (RH) along one vertical channel in the external wall of one building has been monitored. Measurements startedduring construction and presented herein are resu

This paper addresses the inverse problem of reconstructing a medium’s instantaneous, nonlinear response to electromagnetic excitation. Using reflection and transmission data for an almost arbitrary incident field on a homogeneous slab, we are able to obtain the nonlinear constitutive relations for both electric and magnetic fields, with virtually no assumptions made on the specific form of the rel
