Engineers working on safety critical software development must explicitly specify trace links as part of Impact Analyses (IA), both to code and non-code development artifacts. In large-scale projects, constituting information spaces of thousands of artifacts, conducting IA is tedious work relying on extensive system understanding. We propose to support this activity by enabling engineers to reuse
Popular Abstract in Swedish Forskningsprojektet som rapporteras i denna avhandling har två övergripande mål. Det första målet är att utveckla testinstrument avsett för avancerade svenska inlärare av engelska, som genererar reliabla och valida testpoäng kopplat till receptiv kunskap avseende engelska kollokationer som en specifik förmåga. Med kollokationer avses konventionaliserade och frekvent förThe research reported in this thesis has two main aims. The first aim is to develop tests capable of yielding reliable and valid scores of receptive knowledge of English collocations as a single construct, for use with advanced L2 learners of English. Collocations are seen as conventionalized, recurring combinations of words, and the targeted types are adjective + NP and verb + NP. The second aim
Correct estimation of symbol timing, Carrier Frequency Offset (CFO), and Signal-to-Noise Ratio (SNR) is crucial in Orthogonal Frequency Division Multiplexing (OFDM) communication. Typically, high estimation accuracy is desired, but often comes with increased complexity. Which has a direct repercussion in energy consumption. In this article, an architecture based on Sign-Bit estimation with low com
Popular Abstract in Swedish Från mitten av 1970-talet utvecklades i Sverige en ny form av behandling för missbrukare av narkotika och alkohol: Miljöterapi med psykoterapi. Miljöterapin innebar en längre tids drogfri vistelse på behandlingshem där ett konstruktivt, bejakande och människovärdigt klimat avsågs vara behandlande dygnet runt. Psykoterapin var i regel schemalagd transaktionsanalytisk (TAThis monograph studies the outcomes of transactional analysis (TA) psychotherapy with addicts of heavy drugs in long time residential treatment (one year or more) at Swedish therapeutic communities (TCs) during the 1990s. Two sets of data were obtained: The primary material concerned results of approximately one year of TA-therapy; the secondary specific TA-therapy results versus total mileau ther
A novel method for the evaluation of interfacial tension of high viscosity polymer melts is described. The method involves the tracking of the shape evolution of a highly deformed droplet of one material imbedded in a second one. This makes it possible to determine the interfacial tension over a relatively short time period. The imbedded material is initially either a fiber or a disk. The techniqu
Analytic expression for the exact bit error probability of the (7,5) convolutional code was discussed. Recursive systematic encodes which became especially important as component encoders in concatenated coding schemes were also studied. This technique can calculate the probability distribution of the output log-likelihood ratios of the Max-Log-MAP algorithm in analytic form.
Primers for amplification and sequencing of partial glyceraldehyde-3-phosphate dehydrogenase (gpd) gene were designed for lichenized fungi. The 5' gpd primer is most probably fungal specific, since a BLAST search in GenBank found identical sequences only from ascomycetous taxa, whereas the 3' gpd primer was more universal. Utility of the gpd primers and previously designed beta-tubulin primers was
A simple and effective procedure is described for the determination of the best-fit parameters of a given model of a surface structure by analysis of low energy electron diffraction (LEED) intensities. The procedure involves a nonlinear minimisation of chi(2) for the comparison of experimental and calculated intensities as a function of the parameters of the model structure. The minimisation is ca
A low intake of calcium is widely considered to be a risk factor for future fracture. The aim of this study was to quantify this risk on an international basis and to explore the effect of age, gender and bone mineral density (BMD) on this risk. We studied 39,563 men and women (69% female) from six prospectively studied cohorts comprising EVOS/EPOS, CaMos, DOES, the Rotterdam study, the Sheffield
Caloplaca asserigena is shown to be the correct name for what has been called C. assigena. A description is provided, and it is reported to have a unique anthraquinone not previously known within Teloschistaceae. A recent find from thin twigs of Helianthemum oelandicum on the Swedish island of Öland in the Baltic is reported and its ecology is summarized.
The soot particle size distribution was studied via numerical simulation under diesel like engine conditions using a detailed kinetic soot model. Two different mathematical methods of the soot model description have been used in this work. In the first part of the work, the method of moments is presented. In addition, a so called sectional method for the soot particle size distribution function in
OBJECTIVE: To explore the risk factors that have been suggested to be associated with the development of SLE. METHODS: A case-control study was performed and a questionnaire was developed to obtain the data. Consecutive female incident cases diagnosed between 1981 and 1999 in a defined geographical area in southern Sweden were included. Controls, matched for calendar year of birth, were selected r
This dissertation deals with the modern predicament of the Rabha or Kocha people, their survival in the forest and their quest for identity. Rabhas are one of India's indigenous or tribal people, and they live in the jungle tracts where the Himalayan mountains meet the plains of Bengal. When the area came under British rule and was converted into tea gardens and reserved forests Rabhas were forced
