Improved add-compare-select and branch metric units are presented to reduce the complexity in the implementation of trellis-based decoding architectures. These units use a complementary property of the best rate 1/2 convolutional codes to reduce both area requirements and power consumption in a silicon implementation with no loss in decoding performance. For a 0.13μm CMOS process, synthesized comp
The fourth generation broadband (4GBB) concept aims for ubiquitous and high-speed data communication over the existing twisted copper pairs between the last distribution point and the customer premise equipment. Although it saves deployment cost for the last-mile communication, using the existing copper infrastructure makes the system vulnerable to crosstalk due to electro-magnetic coupling from t

Benign paroxysmal positional vertigo (BPPV) is a common cause of vertigo and can be successfully treated with particle-repositioning procedures or habituation exercises. However, some patients do not tolerate this treatment. The aim of the study was to investigate the possibility of treating patients with BPPV, where treatment at first seemed too demanding for the patients, using a descriptive stu
I detta konferensbidrag ifrågasätter jag åsikten att litteraturteori inte bör läras ut på gymnasienivå. Enligt den franske litteraturteoretikern Tzvetan Todorov bör läraren på denna nivå endast lära ut litterära verk, inte teori. Teorin borde endast användas som ett osynligt verktyg. Min hypotes är att litteraturteorin kan användas framgångsrikt på gymnasiet. Viss insikt i teorin kan bidra till atIn this paper I challenge the opinion that literary theory should not be taught at upper secondary level. According to French literary theorist Tzvetan Todorov, the teacher at this level should aim at teaching literary works, not theory. Theory should only be used as an invisible instrument. My hypothesis is that literary theory can be used successfully at upper secondary level. A certain insight
The papers in this volume explore the cognitive neuroscience of second language acquisition from the perspectives of critical/sensitive periods, maturational effects, individual differences, neural regions involved, and processing characteristics. The research methodologies used include functional magnetic resonance imaging (fMRI), positron emission tomography (PET), and event related potentials (
Telia and Ericsson have executed a joint project to evaluate the Ericsson WCDMA experimental system in Stockholm, Sweden. This system has been an important tool for gaining valuable handson WCDMA experience and to support the development of the commercial 3G WCDMA system. Some results from the ongoing tests are presented in this paper.
Popular Abstract in Swedish I Sverige bestäms fastighetsgränsers sträckningar i första hand av gränsmärken på marken, därefter av förrättningskartor och mätuppgifter. Under senare år har efterfrågan på digital fastighetsinformation ökat kraftigt, inte minst beträffande lägesnoggranna gränsdata i den nationella registerkartan. Den utvecklade positioneringstekniken med GPS utgör idag en grundförutsäIn Sweden, the course of a property boundary is first and foremost determined by boundary marks on the ground, and only secondly by cadastral survey plans and measurements. In recent years, the demand for digital property information has increased substantially, not least in respect of accurate boundary data in the national cadastral map. Today, well-established techniques such as GPS positioning
The adverse effects from reactions of reactive aggregates in concrete dams are well known worldwide. The mechanisms ruling alkali silica reactions (ASR) are partly but not fully understood. A majority of the Swedish concrete dams are so far considered to be protected from ASR due to the common use during the 50:s, 60:s and 70:s of the Swedish low alkali cement Limhamn LH. Today there is a discussi
