This paper presents new methods trellis source coding at rates above and below one. The new schemes have in common a code design based on branch correlation, a large reproducer alphabet, and an encoder based on either the Viterbi algorithm or a tailbiting MAP technique. The methods are easily adapted to various bit rates, but here only the results for R = 2 and R = 1/2 bits per source sample are p
The secondary structure of proteins is crucial for proper function of the protein in biological systems. Peptide T, an octapeptide from the envelope glycoprotein gp120 of the HIV virus, has previously been shown to be responsible for binding to the CD4 receptor on T helper/inducer lymphocytes. NMR studies showed that the four C-terminal amino acid residues of peptide T adopted a beta-turn conforma
Hakkarainen and Sintonen (2002) praise the descriptive adequacy of Hintikka's Interrogative Model of Inquiry (imi) to describe children's practices in an inquiry-based learning context. They further propose to use the imi as a starting point for developing new pedagogical methods and designing new didactic tools. We assess this proposal in the light of the formal results that in the imi characteri
Popular Abstract in Swedish Många material är kristallina – inte bara ädelstenar, utan även alla metaller och keramiska material består av kristaller. Till och med många proteiner och t.ex. acetylsalicylsyra, basen till aspirin, bildar kristaller. När någonting kallas kristallint menar man att atomerna sitter på särskilda platser och i en bestämd, regelbunden ordning. De flesta material är polykriSemiconducting nanowires have attracted scientific attention for more than 20 years due to their potential applications in electronic devices, as sensors, and in solid state lighting. These applications require high quality nanowires to begin with. Achieving such good control over the growth of nanowires is not trivial and requires profound understanding of the underlying processes. In this thesis
Decision analysis concerned with investments in fire safety is discussed. Particular attention is directed at the treatment of uncertainty, the evaluation of consequences, and the choice of a decision rule for use in this context. An approach involving use of a decision rule based on the principle of maximizing expected utility, together with a complementary evaluation of the decision alternatives
Considerable progress has been achieved during the last few years in the accuracy of Multiconfiguration Hartree-Fock and Dirac-Fock calculations. Recent results for light atoms include isotope shifts, hyperfine structures, and probabilities for allowed, intercombination, forbidden, and hyperfine-induced transitions. All have been computed using systematic methods which allow for an estimate of the
In this case study we analyzed the traces of spontaneous reactions of Youtube users when confronted with the short clip ’You wouldn’t Steal a Car’, that was used by the Motion Picture Association of America (MPAA) to influence people not to download copyrighted material from the Internet. This film has become an important cultural icon, which to a certain degree has shaped a whole generation of fi
Fall is the most common cause of serious work related accidents. Falls and related injuries not only cause suffering for individuals, but also means a high economic burden to industries and society. The objective of the study was to use a walkway with in-built force plate, adjustable inclination and surface to assess how risks of slips and falls vary due to inclination and friction of the walkway
