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
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

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
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
We present a detector that, by thresholding the output of the matched filter, gives MLSD-decisions on binary, antipodally modulated symbols that have been corrupted by intersymbol interference and additive Gaussian noise. The detector is simple in structure, consisting of a whitened matched filter and two variable thresholds for each symbol to be detected. The detector will make decisions on some,
We want you to feel safe and secure as a student. That is why we are committed to providing a safe learning environment for you and all of our students. Talk to someone you trustIf you feel victimised, it is important to talk to someone you trust at Lund University. This can be a way to get support and perspective on what has happened. It is important to us that our students feel safe, and we have

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. S
Objectives: To compare in an in vitro kinetic model the pharmacodynamics of moxifloxacin and levofloxacin with a concentration-time profile simulating the human free non-protein bound concentrations of 400 mg moxifloxacin intravenous (iv) once daily, 500 mg levofloxacin iv once daily and 750 mg levofloxacin iv once daily against strains of Streptococcus pneumoniae, Staphylococcus aureus, Klebsiell

Background: Blood lead concentrations (B-Pb) were measured in 3 879 Swedish school children during the period 1978-2007. The objective was to study the effect of the proximity to lead sources based on the children's home and school location. Methods: The children's home address and school location were geocoded and their proximity to a lead smelter and major roads was calculated using geographical
This thesis is based on four papers (A-D) treating filtering, smoothing, and maximum likelihood (ML) estimation in general state space models using stochastic particle filters (also referred to as sequential Monte Carlo (SMC) methods). The aim of Paper A is to study the bias of Monte Carlo integration estimates produced by the so-called bootstrap particle filter. A bound on this bias which is inv
Context. With its origin coming from several sources (Big Bang, stars, cosmic rays) and given its strong depletion during its stellar lifetime, the lithium element is of great interest as its chemical evolution in the Milky Way is not well understood at present. To help constrain stellar and galactic chemical evolution models, numerous and precise lithium abundances are necessary for a large range
In this paper I have asked how EU parliament politicians uses arguments to discuss the situation in Catalonia, hoping to be able to cast light on EU view of separatism within the union. Within the EU there are several separatist cases, France, Belgium, Italy, Spain and the United Kingdom (which was part of EU until quite recently). This means that separatism is a delicate political question, but b
A great part of the soil remediation projects in Sweden today are being carried out on heterogeneous contaminated areas where for example industrial activities have been going on for a long time. In many cases waste from the industrial processes have been dumped or spread out on the property, and there is no pattern in the occurrence of contaminants. The distribution of the concentration of the co
Background: Hypoxia and large tumor volumes are negative prognostic factors for patients with head and neck squamous cell carcinoma (HNSCC) treated with radiation therapy (RT). PET-scanning with specific hypoxia-tracers (hypoxia-PET) can be used to non-invasively assess hypoxic tumor volume. Primary tumor volume is readily available for patients undergoing RT. However, the relationship between hyp
Ovako Ajax me, in York, South Carolina, USA manufactures seamless steel rings. The rings are made from blocks, which are heated, pressed, punched and then rolled to desired size and shape. Due to tougher competition on the seamless steel ring market, it is necessary to know the total production time for an order of specific rings, in order to be able to price the rings correctly and plan the prod
