Custom Datapaths for DSP ASICs Methodology and Implementation

This thesis regards datapath design and analysis at several abstraction levels. Five papers are presented that focus on datapath design for mobile communication systems and design methodologies for such datapaths. Paper I discusses different aspects of Turbo channel decoder design for high speed and low power applications. It is shown that critical path delay is significantly reduced by simple re

Evaluation of long-term functional status in first-ever stroke patients in a defined population

Medical, social and ADL variables were registered within 48 hours of stroke onset and 6 and 12 months later in 346 first-ever stroke patients. One year after stroke onset 27% of the patients were dead. 78% of the surviving patients were living in their own homes, 10.6% in old people's homes with no medical facilities and 9.5% in nursing homes. A health index was used for ADL evaluation and the qua

The use of neutral lipid fatty acids to indicate the physiological conditions of soil fungi

The usefulness of measuring neutral lipid fatty acids (NLFAs) and phospholipid fatty acids (PLFAs) separately in order to interpret perturbation effects on soil and compost microorganisms has been studied. Initially the NLFA/PLFA ratios were studied in different soils. Low ratios were found for fatty acids common in bacteria, especially for cyclopropane fatty acids. Higher ratios were found for fa

Separation of closely related asymmetric Penicillia by pyrolysis-gas chromatography and mycotoxin production

The relationships among nine different isolates of Penicillium crustosum were studied by pyrolysis-gas chromatography (Py-GC) coupled with a pattern recognition analysis (PR). The results obtained were compared to mycotoxin production profiles of the isolates. Based on the Py-GC analyses the isolates could be divided into two well-differentiated groups, and one of these groups could be further sub

Mellan klient och rättssystem : Tvångsvård av barn och unga ur socialsekreterares perspektiv

Popular Abstract in Swedish Den här avhandlingen fokuserar på socialsekreterares utredningsarbete av barn och unga inom socialtjänsten. Syftet har varit att beskriva och analysera tvångsvårdsprocessen ur socialsekreterares perspektiv, samt förstå och förklara hur detta påverkar barnavårdspraktiken. Det empiriska materialet består av barnavårdsakter och fokusgruppsintervjuer med socialsekreterare. This dissertation focuses on assessments concerning children and young persons in the Social Services. The aim has been to describe and analyse the compulsory care process from a social worker perspective, and to understand and explain how this affects the practice of child welfare. I have used case files from the Social Services and focus group interviews with social workers as empirical data. Th

Acute effects of D-1 and D-2-receptor agonist and antagonist drugs on somatostatin binding, inhibition of adenylyl cyclase activity and accumulation of inositol 1,4,5-trisphosphate in the rat striatum

A recent study carried out by our group demonstrated that exogenous dopamine increases the somatostatin (SS) receptor–effector system in the rat striatum. The present study examined the participation of the D1- and D2-dopaminergic systems in the modulation of the rat striatal SS receptor–effector system by use of the D1-receptor agonist and antagonist SKF 38393 and SCH 23390, respectively, and the

High-spin States in the A=39 Mirror Nuclei 39Ca and 39K

High-spin states of the mass A = 39 mirror pair K-39 and Ca-39 were investigated via the fusion-evaporation reaction Si-28+O-16 at 125 MeV beam energy. The GAMMASPHERE array in conjunction with the 4 pi charged-particle detector array MICROBALL and neutron detectors was used to detect gamma rays in coincidence with evaporated light particles. The results of the first high-spin study of the T-z = -

Light exotic isotopes: recent beam developments and physics applications at ISOLDE

This paper is divided in three parts: (i) the measurement of yields and decay losses of Li and Be isotopes released from a thin foil tantalum target at the CERN/ISOLDE PS-Booster; (ii) results from β-decay experiments on 12Be and 14Be, an improved half-life of 21.49(3) ms has been obtained for 12Be; (iii) the β-decay of 9C. An outline of the analysis procedure to determine the branching at high ex

The effect of pasture on starling (Sturnus vulgaris) breeding success and population density in a heterogenous agricultrual landscape in Southern Sweden

Populations of European starlings have declined over large parts of northern and western Europe during the last 20 years. It has been suggested that reduced availability of pasture in the agricultural landscape was one reason for this decline. To investigate this, breeding colonies for starlings were established in southern Sweden, in agricultural landscapes with different availabilities of pastur

Richard P. Bunge memorial lecture. Nerve injury and repair--a challenge to the plastic brain.

Repair and reconstruction of major nerve trunks in the upper extremity is a very challenging surgical problem. Today, there is no surgical repair technique that can assure recovery of tactile discrimination in the hand of an adult patient following nerve repair. In contrast, young individuals usually attain a complete recovery of functional sensibility. The outcome from nerve repair depends mainly

Genus och utbildning : ekonomisk-historiska studier i kvinnors utbildning ca 1870-1970

Popular Abstract in Swedish Avhandlingen består av tre delar. Den första, Från utbildningsmarknad till of-fentlig utbildning. Svensk flickskola 1874-1962, behandlar dels integrationen av flickornas sekundärutbildning i den offentliga utbildningsorganisationen, dels förstärkningen respektive försvagningen av denna speciellt genuskodade utbild-ning. Sekundärutbildningen har varit könssegregerad och The thesis is divided into three sections. The first, “From an education market to public education. The Swedish girls’ school 1874-1962”, deals with the integration of girls’ secondary education into the public education system, as well as with the strengthening and weakening of this special, gender-coded education. Secondary education was gender segregated and integration involved a process of s

On the modelling of turbulent flow and mixing in stirred reactors

This thesis concerns the numerical simulations and modelling of the flow structure and scalar transport in stirred reactors. For this Large Eddy Simulations (LES) have been used. The flow situation in a stirred reactor includes several flow phenomena that are not well predicted by "standard" two-equation models, e.g. swirl, stagnation points and anisotropic turbulence. Also, using LES one can obta

Simultaneous videoradiography and computerized pharyngeal manometry--videomanometry

To obtain more information about muscle function in patients with dysphagia, simultaneous barium swallow and computerized pharyngeal manometry with solid-state pressure transducers was employed for the evaluation of the pharynx and the pharyngoesophageal segment (PES) in 30 consecutive patients. The manometry catheter was positioned under fluoroscopic control, providing localized measurements of t

Essays on: Application of Cross Sectional Efficiency Analysis

Popular Abstract in Swedish Denna avhandling består av tre olika uppsatser. Den första uppsatsen, Technical Efficiency and Ownership: The Case of Booking Centres on the Swedish Taxi Market” behandlar problemet med konkurrens på lika villkor. Upprinnelsen till uppsatsen var diskussioner mellan privata och offentliga aktörer på den svenska taximarknaden. De privata aktörerna hävdade att de offentligThis thesis consists of three different essays, all of which have arisen from a practical problem. In the first essay, “Technical efficiency and ownership: The case of booking centers in the Swedish Taxi Market” the purpose is to examine the question of competition on an equal basis between privately and publicly owned booking centers in the Swedish taxi market. One way to answer this question is
