Popular Abstract in Swedish Optoelektronik genomgår för närvarande en otrolig utveckling, inte minst på grund av de senaste årtiondenas kommersialisering och utveckling av hemelektronik som kompaktdiskar och digitalkameror. Denna utveckling har drivit en blomstrande global tillväxt för optoelektroniska företag som varje år utvidgar sina erbjudanden av optiska komponenter i hård konkurrens. UtvecklThe present thesis describes a number of aspects of modern electro-optical measurement technology also known as bio-photonics; this includes instrumentation, applications, sample interaction and data interpretation. The methods employed operate over several domains, and light measurements are discretized both in intensity, space, angle, time, polarization and energy. Mainly the spectral domain is

Popular Abstract in Swedish Insulin frisätts från B-cellerna i bukspottkörteln (pankreas) när blodsockerhalten ökar över den normala (80-100 mg per dl), exempelvis efter en kolhydrat- och sockerrik måltid. Medan ?friska? B-celler har förmågan att reagera kraftigt redan på små (10%) förändringar i blodsockerhalten, så utvecklar ?ålders-diabetiska? B-celler en blodsockerblindhet och insulinfrisättniEndocrine cells as well as neurons release their hormones and transmitters by regulated exocytosis. In the pancreatic B-cell, stimuli like glucose initiate biochemical and electrical processes that culminate in influx of Ca2+, which then triggers exocytosis of insulin-containing granules. Fusion of the secretory vesicles occurs rapidly upon Ca2+-influx but requires a granule to be ?primed? by an A

In market-driven software development it is crucial to produce the best product as quickly as possible in order to reach customer satisfaction. Requirements arrive at a high rate and the main focus tends to be on the functional requirements. The functional requirements are important, but their usefulness relies on their usability, which may be a rewarding competitive means on its own. Existing met

A particle filter based solution to the out-of-sequence measurement (OOSM) problem is proposed. The solution is storage efficient, while being computationally fast. The filter approaches the multi-OOSM problem by not only updating the estimate at the most recent time, but also for all times between the OOSM time and the most recent time. This is done by exploiting the complete in-sequence informat

Previous depth buffer compression schemes are tuned for compressing depths values generated when rasterizing static triangles. They provide generous bandwidth usage savings, and are of great importance to graphics processors. However, stochastic rasterization for motion blur and depth of field is becoming a reality even for real-time graphics, and previous depth buffer compression algorithms fail

A method is described for production of time series of atmospherically distorted wavefronts following Kolmogorov statistics. The method uses Taylor's hypothesis (`frozen turbulence') to generate the temporal development of the aberrations caused by an atmospheric turbulence layer. An arbitrary number of turbulence layers can be used to generate the final wavefront.

In this paper we introduce a new coding scheme - so-called laminated turbo codes. It is characterized by a block-convolutional structure that enables us to combine the advantages of a convolutional encoder memory and a block-oriented decoding method. We show that this block-convolutional structure is superior in terms of its error correction capability compared to the pure block structure of the c

Our abilitiy to estimate speaker age was investigated with respect to stimulus duration and type as well as speaker gender in four listening tests with the same 24 speakers, but with four different types of stimuli (ten and three seconds of spontaneous speech, one isolated word and six concatenated isolated words). Results showed that the listeners' judgements were about twice as accurate as chanc

At the end of the 1980s, a tri-polar world comprising the US, EU and Japan emerged. However, the economic turbulence of the early 21st century has destabilized this order, and the rise of other Asian powers has implications for the formation of a new economic configuration. This book discusses the probability of the different tentative global economic power balances to emerge, as well as the diff
