In control theory there exist two convenient representations of a model, which are transfer functions and state-space matrices. However, structure in the transfer functions is not clearly seen in the state-space form, and on the other hand structure in the state-space form is not clearly seen in the transfer functions. The main reason for this is that Laplace transformation destroys most types of

A collection of original chapters focusing on young people and their political involvement, their use of the internet and other new media for learning the roles and practices of various forms ofcitizenship. The collection is analytically framed by the current dilemmas of democracy

Crosstalk is one of the main limiting factors in the data rates achievable by digital subscriber line (DSL) systems, and several algorithms have been proposed to mitigate this impairment. In this paper, we compare the capacity of binders under different crosstalk-mitigating techniques. When computing capacity, we also compare two different power constraints: either on the total power in the binder

In the autumn of 2011, the course “The City: Boundary Transgressions and Visual Expressions” was given for the first time. Formally placed at the Division of Art History and Visual Studies, the course is a collaboration with the Division of Social Anthropology and is directed towards students from a range of disciplines within the fields of the humanities and social sciences. The course includes

Boken innehåller praktiska övningar på moment inom olika delar av grammatiken: morfologi och ordklasser, ordbildning, syntax och språklig variation. Till övningarna finns facit med kommentarer. Kategoriseringarna och användningen av termer bygger på läroboken Svensk universitetsgrammatik för nybörjare, som i stort behandlar samma stoff. Övningsboken fungerar dock oberoende av läroboken, eftersom v

Det finns en lång tradition av att placera unga människor som begår brott på ungdomshem. Ute på landet, bortom storstadens förmodat destruktiva inflytande, ska de behandlas och anpassas till ett konventionellt liv. Ungdomarna är i högstadie- eller gymnasieåldern. De förväntas gå i skola, de har gått i skola och de vill gå i skola, åtminstone de flesta och i princip. Men skolarbetet har haft en ned

Urban traffic involves frequent acceleration and deceleration. During deceleration, the energy previously used to accelerate the vehicle is mainly wasted on heat generated by the friction brakes. If this energy that is wasted in traditional IC engines could be saved, the fuel economy would improve. One solution to this is a pneumatic hybrid using variable valve timing to compress air during decele

Window decoding schedules are very attractive for message passing decoding of spatially coupled LDPC codes. They take advantage of the inherent convolutional code structure and allow continuous transmission with low decoding latency and complexity. In this paper we show that the decoding complexity can be further reduced if suitable message passing schedules are applied within the decoding window.

Rapporten beskriver hur subjektiva faktorer påverkar medborgarnas uppfattning av staden och deras beteende, samt hur man kan bedöma eller mäta dessa faktorer. Vad som ingår i dessa faktorer resp. vilka indikatorer som speglar dem diskuterades först med ansvariga från olika kommuner i Sverige. 16 personer från11 kommuner intervjuades med detta syfte. Resultaten från intervjuerna sammanfattas i denn

We show that photoelectron spectroscopy (PES) due to its surface sensitivity can be used as a straightforward method to quantify the PMMA resist residues which remain on SiO₂ surfaces after electron beam exposure and resist development. The attenuation of the SiO₂ valence band and Si2p photoelectrons has been measured by using a photoelectron microscope and it has been found

Clock nets are the major source of power consumption in large, high-performance ASICs and a design bottleneck when it comes to tolerable clock skew. A way to obviate the global clock net is to partition the design into large synchronous blocks each having its own clock. Data with other blocks is exchanged asynchronously using handshake signals. Adopting such a strategy requires a methodology that

Spatially coupled regular LDPC code ensembles have outstanding performance with belief propagation decoding and can perform close to the Shannon limit. In this paper we investigate the suitability of coupled regular LDPC code ensembles with respect to rate-flexibility. Regular ensembles with good performance and low complexity exist for a variety of specific code rates. On the other hand it can be

In this paper we describe how techniques for refactoring can be used for visual editing of hybrid languages, that is, languages that have both a visual and a textual syntax. Textual languages have name rules that define how name uses are bound to name declarations. These bindings often correspond to connections in the visual language, and need to be taken into account in order to implement the vis
