We consider the problem of covering arbitrary polygons with rectangles. The rectangles must lie entirely within the polygon. (This requires that the interior angles of the polygon are all greater than or equal to 90 degrees.) We want to cover the polygon with as few rectangles as possible. This problem has an application in fabricating masks for integrated circuits. In this paper we will describe
Baker’s yeast, Saccharomyces cerevisiae’s potential in industrial biotechnology for producing valuable products e.g. biofuels, bulk chemicals, bio-flavours and pharmaceuticals is established. In order to achieve efficient production, the intracellular balance of the NADH/NAD + redox couple must be monitored and maintained, as this influences the feasibility of over 100 reactions in the cell. My ap

This paper presents an iterative detector that, by thresholding the output of the matched filter, gives maximum-likelihood sequence detector (MLSD) decisions on binary, antipodally modulated symbols that have been corrupted by intersymbol interference and additive Gaussian noise. The detector will make decisions on some, but often not all, of the symbols in a transmitted sequence, and those decisi
We consider the problem of simplifying a triangle mesh using edge contractions, under the restriction that the resulting vertices must be a subset of the input set. That is, contraction of an edge must be made onto one of its adjacent vertices. In order to maintain a high number of contractible edges under this restriction, a small modification of the mesh around the edge to be contracted is allow
Sverige har haft stora framgångar inom skidåkningen där längdlandslaget har tagit många medaljer i olika mästerskap. Det finns ett stort intresse för skidåkning inte bara på elitnivå utan även bland vanliga motionärer. Ett sådant intresse skapar efterfrågan och behov av anläggningar och områden som möjliggör utövande. Skidåkning kan utövas på mer än ett sätt med varierande påverkan på det områdeIn Sweden skiing has been very popular for a long time. Due to the popularity there is a need for land to practice the sport. Cross- country skiing is one kind of skiing that is popular. If you want to go on a skiing tour you can either chose to make your own tracks or use tracks made by machines. When you make your own tracks the imprint that is left in nature is small. Tracks made by machines
Det svenska straffrättsliga systematiken är uppbyggt så att den som uppfyller rekvisiten i en brottsbestämmelse är ansvarig i strikt gärningsmannaskap. Men för ett tillfredsställande system krävs det att även andra involverade personer kan tillskrivas straffansvar vilket löses genom medverkansansvaret. Uppsatsen syftar till att utreda hur långt gärningsmannaskapet och medverkansansvaret sträcker sThe Swedish criminal law system is structured so that those who meet the necessary conditions in a criminal provision are liable as perpetrators. But for a satisfactory system, it is required that other people involved also can be attributed criminal liability, which is solved through the responsibility for complicity. This thesis aims to investigate the range of the perpetration and responsibilit
Våldtäktsbrottet har, inom svensk rätt, genomgått omfattande förändringar de senaste decennierna. Begreppet har breddats och kommit att innefatta allt fler sexuella handlingar. Utvecklingen har följts av omfattande diskussioner samt medialt omdebatterade domar. Den så kallade samtyckesregleringen, där rekvisiten våld och hot avskaffas till förmån för ett bristande samtycke, har haft en central posUnder Swedish Penal Law the rape offense has undergone extensive changes in the recent decades. The concept of rape has been broadened and extended to cover more sexual acts then before. The trend has been followed by extensive discussions and media controversial judgments. The so-called consent regulation, where the elements of violence and threats would be replaced in favor of the victim’s lack

In this paper we present an approach to gaining increased anonymity from authorities within a VANET. Standardization organizations and researchers working on VANETs recognize privacy as highly important. However, most research focuses on privacy from other vehicles and external attackers, as opposed to privacy from system-administrating authorities. Our proposed solution forces authorities to reso
The Learning with Errors problem (LWE) is one of the main candidates for post-quantum cryptography. At Asiacrypt 2017, coded-BKW with sieving, an algorithm combining the Blum-Kalai-Wasserman algorithm (BKW) with lattice sieving techniques, was proposed. In this paper, we improve that algorithm by using different reduction factors in different steps of the sieving part of the algorithm. In the Rege
The Learning with Errors problem (LWE) has become a central topic in recent cryptographic research. In this paper, we present a new solving algorithm combining important ideas from previous work on improving the BKW algorithm and ideas from sieving in lattices. The new algorithm is analyzed and demonstrates an improved asymptotic performance. For Regev parameters q = n^2 and noise level \sigma = n

IMPORTANCE: Stroke survivors experience changes in participation level, satisfaction with participation, and participation balance, making it necessary to have a validated tool for their assessment. OBJECTIVE: To evaluate the psychometric properties of the Spanish version of the Satisfaction With Daily Occupations and Occupational Balance (SDO-OB) in stroke survivors. DESIGN: Psychometric study.
