Providing flexibility in a convolutional encoder

In future radio systems, flexible coding and decoding architectures will be required. In case of the latter, implementing architectural flexibility with regard to low power issues is a challenging task. The flexible encoding platform in this paper is a first step toward this envisioned decoder. It generates a wide class of codes, starting with convolutional codes. As an extension to this, turbo co

Navigation, findability and the usage of cultural heritage on the web: an exploratory study

The present thesis investigates the usage of cultural heritage resources on the web. In recent years cultural heritage objects has been digitalized and made available on the web for the general public to use. The thesis addresses to what extent the digitalized material is used, and how findable it is on the web. On the web resources needs to be findable in order to be visited and used. The study i

New Methods for Enzyme Hydrolysis, Analysis, and Characterization of Modified Cellulose

Cellulose can be chemically modified to produce derivatives with specific properties. Knowledge of correlations between the modification reaction, substituent distribution, origin of cellulose and properties are importaint in order to design processess so as to produce derivatives with the desired properties. This thesis describes research on newly developed analytical methods for the analysis of

Optical parametric oscillator based lidar system applied to atomic mercury monitoring

Field measurements of mercury emissions has been performed by using a mobile lidar system. In this system an Nd:YAG-pumped OPO (Optical Parametric Oscillator) laser system is employed to generate a narrow band (better than 0.2 cm-1) UV beam at the mercury resonance absorption line at 253.65 nm. An inter-comparison of the lidar system and two different point monitoring systems has been performed sh

Jet Impingement and Infrared Heating of Cylindrical Foods. Flow and Heat Transfer Studies

Popular Abstract in Swedish Jet impingement och infraröd strålning är metoder för snabb värmeöverföring som kan användas för att snabba upp värmeprocesser i livsmedelsindustrin. Värmningshastigheten påverkar viktiga egenskaper hos livsmedlet, t.ex. brunfärgning. Jet impingement består av riktade strålar av luft med hög hastighet som träffar ytan på livsmedlet och minskar gränsskiktet mellan luftenRapid heat transfer methods such as jet impingement and infrared radiation can be used to speed up thermal processing in the food industry. The heating rate affects important food characteristics, such as colour. Jet impingement consists of directed jets of air with a high velocity that impinge on the food surface, which reduces the velocity boundary layer between the air and surface and gives a f

Calcium transporting ATPases in plant cells.

Plant cells carry Ca2+ ATPases to maintain the low resting level of cytosolic Ca2+ (0.1-0.2 µM) found in all eukaryotes. Plant Ca2+ ATPases are mainly located in the plasma membrane, the endoplasmic reticulum and in the vacuolar membrane, and consequently large Ca2+ gradients are created across these membranes. The Ca2+ gradients are used by the cell to transmit information in a variety of physiol
