For evaluation of specific antenna arrangements in wireless communication systems we need physical channel models that take into account the directional domain. Here we propose a practical approach to wireless channel modeling in, particularly, mobile communication systems, by using an assumption that the channel can be divided into separate parts or regions that can be treated and modeled individ

I arbete och umgänge med människor med någon form av kognitivt funktionshinder har bilder och symboler använts länge. Syftet med denna rapport om digitala bilders betydelse för personer med kognitiva funktionshinder är att visa på att det finns en utbredd användning av digitala bilder inom skola, vård och omsorg, och att det finns mycket kunnande inom området. Jag hoppas också att rapporten ska tj

Laser spectroscopy of free atoms has been pursued for 25 years starting in the visible region and with a constant thrust towards shorter wavelengths. A review of generation schemes and atomic-physics experiments in the short-wavelength region is given. Processes in ions and inner shells occur on a very fast timescale setting special demands on the sources. Using picosecond laser technology efficie

Popular Abstract in Swedish Avhandlingen består av fyra kapitel. Efter det inledande kapitlet används i kapitel två och tre ekonomiska experiment för att undersöka hur deltagare fördelar ett överskott mellan sig då det finns två fokalpunkter. Kapitel fyra undersöker huruvida en penningpolitisk störning har asymmetriska effekter på de svenska länens sysselsättning. I kapitel två, samförfattat med This thesis consists of two parts. The first part uses economic experiments to investigate how participants choose to divide a surplus in the presence of competing focal points. The second part examines whether a monetary policy shock has asymmetric regional effects. Chapter 2 suggests a simple separation mechanism based on heterogeneity among subjects to understand how they choose equilibrium wh

Biomarker discovery is dependent upon two disciplines: the field of clinical bioanalysis linked to disease aetiology and the application of high level technology platforms for identifying proteins/peptides in complex samples. However, diagnostic biomarker measurements require certain definitions of context that can only be achieved by combining protein science with clinical science. The evaluation

Empiriska data för den föreliggande analysen består av 276 inspelade telefonsamtal till 13 olika sjuksköterskor vid 6 olika vårdcentraler. Samtalen spelades in mellan februari och november 1999. Inspelningarna har transkriberats och analyserats i detalj. Vid analys av telefonsamtalen fann vi att de uppringande presenterade sina problem enligt tre olika format. Det första formatet innebär att den u

Background: The present study examines a population of criminal justice clients for suspected substance-related problems. Aims: It aims to identify variables associated with a history of suicide attempt (SA). Method: 6,836 clients were interviewed with the Addiction Severity Index (ASI). Attempters were compared to nonattempters regarding substance use, medical/psychiatric status, family history,

ABSTRACT: This study is the third within the project Sound, Music, and Eye Movements, and results from the two previous studies examining reading for comprehension revealed no effects on eye movements such as fixation durations and saccade amplitudes with regards to sound environments. Therefore, other eye movement measures were tested in the current study, namely oculomotor control. Participants

Light transillumination was used to study structures inside turbid media. Time-gated viewing was performed to suppress multiply-scattered light and thus improve spatial resolution. We demonstrate that, for the case of scattering-dominated attenuation (scattering coefficient much greater than the absorption coefficient), the detection of early transmitted light will be practically insensitive to va
