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 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,
Experimental oscillator strengths for 19 ultraviolet lines of Pd II have been derived from measurements of line intensities in calibrated Fourier transform spectra, combined with picosecond-pulse laser measurements of radiative lifetimes. Five of these 19 lines, in addition to other Pd nr lines, are present in Hubble Space Telescope/Goddard High-Resolution Spectrograph echelle spectra of the chemi
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
Den ökade användningen av artificiell intelligens inom sjukvården väcker flera rättsliga frågor. En av dessa är hur patientskadeersättning ska hanteras vid patientskador orsakade av AI-baserade medicintekniska produkter (MTP), exempelvis när dessa används för att analysera mammografibilder. Även om AI-tekniken visat på god förmåga att identifiera tecken på bröstcancer är det oundvikligt att fel nåThe increasing use of artificial intelligence in healthcare raises several legal issues. One of those is how patient injury compensation should be handled in case of patient injuries caused by AI-based medical devices (MTP), for example, when they are used to analyze mammography images. Although AI technology has demonstrated a satisfactory level of ability to identify signs of breast cancer, erro
Reflection seismic data were acquired in the Sudret area of Gotland between 6 and 13 November 2023. Objectives of the survey were to obtain images of the subsurface down to the Precambrian basement in the vicinity of two cored boreholes that had been drilled earlier down to about 800 m. The seismic profiles were positioned to provide a better understanding of the sedimentary strata and local struc
BACKGROUND: Changes in Ischemic White matter hyperintensities volume (WMH) on MRI over time are associated with cognitive decline. We investigated whether changes in WMH volume over time exhibit WMH-normalized volume threshold effects on declining cognitive performance and whether these effects on cognition differ between deep white matter hyperintensities (DWMH) and periventricular white matter h
Background: The need for complete staging surgery including hysterectomy for all age patients with borderline ovarian tumors (BOT) is debatable, considering fertility in younger patients and potential higher morbidity in older patients. We aimed to investigate the relapse risk and overall survival in a cohort including patients who underwent conservative surgery (organ-preserving procedures) to miBackground:The need for complete staging surgery including hysterectomy for all age patients with borderline ovarian tumors (BOT) is debatable, considering fertility in younger patients and potential higher morbidity in older patients.

We consider the fundamental problem of assigning distinct labels to agents in the probabilistic model of population protocols. Our protocols operate under the assumption that the size n of the population is embedded in the transition function. Their efficiency is expressed in terms of the number of states utilized by agents, the size of the range from which the labels are drawn, and the expected n
Popular Abstract in Swedish Användningen av fossila bränslen såsom kol, olja och naturgas svarar för mer än 70% av dagens globala utsläpp av koldioxid vilket är det största antropogena bidraget till växthuseffekten. Energieffektivisering och en ökad användning av förnybara energislag, t ex bioenergi, är två nyckelstrategier för att minska utsläppen av växthusgaser. Ett ökat utnytttjande av bioenerThe increased use of biomass for energy is as a key strategy in reducing carbon dioxide (CO2) emission, which represents the largest anthropogenic contribution to the greenhouse effect. In this thesis, aspects of an increase in the utilisation of biomass in the Swedish energy system are treated. Modern bioenergy systems should be based on high energy and land-use efficiency since biomass resource
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
Objective To investigate the basic pharmacodynamic properties of teicoplanin in vitro for Staphylococcus aureus, Staphylococcus epidermidis and Enterococcus faecium. Methods The following experiments were performed: (1) bacterial killing by teicoplanin at different concentrations; (2) bacterial killing by teicoplanin at 8 x MIC against the same strains with inocula of 5x10(3), 5x10(5) and 5x10(7)

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
