This paper proposes a low-complexity two dimensional channel estimator for MIMO-OFDM systems derived from a time-frequency variant channel estimator previously proposed. The estimator exploits both time and frequency correlations of the wireless channel via use of Slepian-basis expansions. The computational saving comes from replacing a two-dimensional Slepian-basis expansion with two serially con

This study investigates the relationship between evidentiality, temporality and epistemic control through detailed interpretive analysis of wine reviews written by Robert Parker, whose outstanding authority in this particular discourse field provides an exceptionally fruitful backdrop for the exploration of credibility in discourse. The material consists of 200 entire reviews, which are divided in

A searchable database of speech samples from more than 100 Swedish dialects is being established for use in research and education. Each dialect is represented by at least 12 speakers. Recordings are made of spontaneous speech as well as words and phrases elicited with a number of specific research goals in mind. This paper summarizes one of these goals, a prosodic typology for the Swedish dialect

Popular Abstract in Swedish Tumörimmunologisk grundkurs: En tumörcell har en gång i tiden varit en vanlig laglydig cell i någon av kroppens vävnader men på grund av arv eller dålig uppväxtmiljö så har denna cell upphört att följa de tillväxt begränsande regler som normala celler rättar sig efter. Förutom att kontrollen av celldelningen upphört så kan tumörcellen uppvisa ett mer eller mindre asociThis study aims at clarifying the role of NO in the immunosuppression induced by in vivo tumor growth and by tumor immunotherapy, and determining whether the inhibition of NO production can be used as an adjuvant in tumor immunotherapy. We have shown previously that tumor cells, glioma (N32) and colon carcinoma (H1D2), when genetically engineered to express such immune stimulatory cytokines as IFN

The article analyses how the Holocauast is represented among Russian nationalists, writing on web-sites.

Decision making is a dynamic process. Alternatives compete over time, and this competition plays out in sensorimotor processes. This is true not just for perceptual decisions or simple categorisation tasks, but also for moral decisions, which are the outcome of a complex interplay of intuition, emotion and reasoning. In this experiment, we first establish a descriptive and causal link between gaze

Popular Abstract in Swedish Att en temperaturskillnad kan ge upphov till en elektrisk ström upptäcktes redan på 1800-talet och fenomenet är känt som den termoelektriska effekten. Denna effekt skulle kunna effektivisera energianvändningen överallt där det går att utnyttja en temperaturskillnad. Ett exempel är i en bil där en stor del av energin som tillförs genom bränsle förloras som spillvärme. OmThermoelectricity is being intensively researched as it is believed to hold great promise for applications in power generation and cooling. One way to quantify the electrical power output of a thermoelectric material is the power factor, a function of electrical conductivity and thermopower. There are relationships between these relevant material properties that make efficient thermoelectric mater

I ett sameuropeiskt Leonardo da Vinci-projekt har utvecklats ett internationellt utbildnings- och praktikpa- ket för blivande sjukhusfysiker [1-3]. Utbildningspaketet innehåller praktiska och kliniska övningsuppgifter där delta- garna tränas i för en sjukhusfysiker vanligt förekommande arbetsuppgifter. Målet har varit att det skall ge sjukhusfysi- kern den praktiska kompetens som krävs av det euro
