In this paper it is shown how a convolutional code can be used either to detect errors or to correct erasures. The erasure correction is related to the error detection. Using the active burst distance lower bounds on the error and erasure correction as well as error detection are obtained for convolutional codes.

Popular Abstract in Swedish Under 1980-talet blev riskerna med blodtransfusioner alltmer uppenbara. Störst uppmärksamhet väckte ett antal fall med spridning av HIV- (AIDS) smitta, men ännu vanligare var spridning av ett virus som kunde orsaka leverinflammation. Dessa risker är numera nästan helt försvunna men dels kvarstår en oro för spridning av nya, okända virus, dels har det visat sig att blodtBlood loss in major arthroplasty may be abundant and often necessitates blood transfusions. These may transmit disease and entail an immunological burden to the recipient. After trauma and surgery, the fibrinolytic system reacts with a short period of increased activity, followed by a fibrinolytic shut-down. In this thesis we investigated the impact of the early fibrinolytic activation on blood

The purpose of this paper is to demonstrate the close interaction between epistemic and evidential stance verbs on the one hand and social hierarchy and power on the other. It is hypothesized that there is a correlation between the degree and intensity of stance verbs and the social context in which they are generated. The data for the study comes from an online bulletin board, in which members ar

As globalisation of economy is developing, the value of “human capital” was discovered as one of the solid basics for sustainable entrepreneurship in a knowledge-based society. Accordingly, the relevance of Participation and Empowerment (P&E) among management approaches has increased significantly. In this anthology, 26 authors from six European countries, networking in the “International Soci

This thesis concerns the prediction of the fluid mechanical conditions in some specific large vessels in the human body. Large vessels are special in the way that the Reynolds number is relatively high and in the case of arteries the flow is pulsatile. The aim is to contribute to the knowledge of flow patterns in large vessels, and ways to predict and measure fluid mechanical parameters such as sh

In summer 1987 most of the multibody dynamics community met at the JPL, Pasadena, to discuss the needs and the open problems in multibody system simulation, especially for space applications. P. W. Likins stated in his survey [16]: “Computational questions focused initially on the selection of subroutines for numerical integration, matrix inversion, or eigensystem analysis,and lately have shifted

Popular Abstract in Swedish Enterostatin är en peptid (en liten del av ett protein) som bildas i magsäcken och tarmen under en måltid. I djurförsök då råttor behandlas med enterostatin har man funnit att både aptiten och kroppsvikten minskade. Den minskade aptiten gällde speciellt för fett. Enterostatin fungerar som en mättnadssignal för fett och kan därför vara viktig för att hindra uppkomsten avThe presence of procolipase and enterostatin in the rat gastrointestinal tract has been investigated. Procolipase was identified, using in situ hybridization and immunohistochemistry, in exocrine cells of the pancreas as well as in chief cells of the fundus region of the stomach. Enterostatin is the activation peptide of procolipase and it has been found to act as a satiety signal for fat. Using a

The most common situation connection with freshwater production from sea water (desalination) is producing a brine waste stream, usually discharged back into sea water. The purpose of this study is to explore the behavior of a dense jet and bottom plume, composed of brine water of heavier effluent into a quiescent homogeneous ambient, discharged into a receiving body of lighter fresh water (tank).

Popular Abstract in Swedish Den enorma variationen av beteenden och utseenden som återfinns i djurriket har i alla år fascinerat och länge förbryllat biologer. Rovdjurens skoningslösa utgallring är en av de stora drivkrafterna bakom evolutionen av alla dessa karaktärsdrag. Rovdjuren är såklart även en viktig strukturerande kraft i sötvattensmiljöer och har där lett till utvecklingen av mängder av The varieties of prey phenotypes that have been revealed in nature are vast and many of these phenotypes are the result of the selective force that predators have had on prey traits in the past. Even within species and populations we see variations due to both differences in the selection forces they live under but also due to individual trait variation. In this thesis I investigate both the direc

Popular Abstract in Swedish Hemolytiskt uremiskt syndrom (HUS) och trombotiskt trombocytopen purpura (TTP) är allvarliga sjukdomar hos barn och vuxna. HUS kännetecknas av mikroangiopatisk hemolytisk anemi (blodbrist med nedbrytning av röda blodkroppar), trombocytopeni (låga blodplättar) och akut njursvikt. Det är den vanligaste orsaken till akut njursvikt hos barn. Typisk HUS utlöses av tarminfektThis study investigated the pathogenesis of hemolytic uremic syndrome (HUS) and thrombotic thrombocytopenic purpura (TTP). (1) The relative roles of lipopolysaccharide and Shiga-like toxin-2 were studied in a mouse model of Escherichia coli O157:H7 infection. Both factors were found to be important for the virulence of the strain and contributed in an additive manner. The mouse model mimicked cert

Leukotrienes are membrane derived bioactive lipids that play an important role in immune responses by initiating and maintaining the inflammatory responses. Leukotriene B4 (LTB4) released at the site of an inflammatory response attracts, activates and prolongs the life of leukocytes and lymphocytes. LTB4 can bind to two recently cloned cell surface G-protein coupled receptors named BLT1 and BLT2.

This study investigates the topic of forgiveness of sins in the mission of the historical Jesus. Gospel material that pertains to the question is authenticated by the use of criteria for historicity and interpreted within the wider context of first-century Judaism as part of a broader reconstruction of Jesus’ career as a healer and prophet. Questions posed and answered concern the historical plaus
