A Flexible FFT Processor
In this paper a flexible FFT processor for OFDM systems is presented. In future wireless systems using OFDM each terminal should be able to handle a wide range of different applications, from pure voice communication to high-speed data transfers, with as little overhead in power consumption and protocol procedure as possible. As the terminals will be battery powered and should be cheap to manufact

Proton-Conducting Sulfonated Aromatic Ionomers and Membranes by Chemical Modifications and Polycondensations
Popular Abstract in Swedish Växthuseffekten och klimatförändringar har de senaste decennierna påskyndat forskning och utveckling av alternativa energikällor, däribland bränslecellen. En första skiss på en bränslecell föddes redan på 1830-talet. Det dröjde dock till 1950-talet innan den första kommersiella bränslecellen användes i ett av NASAs projekt. I Sverige har forskning runt bränsleceller medProton-exchange membrane fuel cells (PEMFC)s are increasingly regarded as promising environmentally benign power sources. Intensive development is today directed towards reducing the cost and increasing the durability of the fuel cell, as well as expanding the operational window for the PEMFC for a range of applications. The proton-conducting membrane is one of the key components in the PEMFC. The

Facket och A-kassan
Inget statligt ingrepp har någonsin haft en så negativ inverkan på den fackliga organisationsgraden i Sverige som den förändring av a-kassornas finansiering som den borgerliga alliansregeringen genomförde från årsskiftet 2006/2007. Under loppet av två år sjönk andelen fackligt anslutna löntagare med sex procentenheter: från 77 procent 2006 till 71 procent 2008. Den 1 januari 2007 höjdes avgifterna
Using circumventing media to counteract authoritarian regimes.
The purpose of this paper is to reflect on how potential circumventing media and communication technologies could potentially assist the information flow when authoritarian regimes decide to block the main channels, such as the Internet and the mobile phone networks. The point of departure is the recent Internet blackouts in countries in the Middle East and North Africa (MENA), such as Egypt, Bahr
