A key open question in the study of multiparticle production in high-energy pp collisions is the relationship between the "ridge"-i.e., the observed azimuthal correlations between particles in the underlying event that extend over all rapidities-and hard or semihard scattering processes. In particular, it is not known whether jets or their soft fragments are correlated with particles in the underl

The Radon transform and its adjoint, the back-projection operator, can both be expressed as convolutions in log-polar coordinates. Hence, fast algorithms for the application of these operators can be constructed by using FFT, if data is resampled at log-polar coordinates. Radon data is typically measured on an equally spaced grid in polar coordinates, and reconstructions are represented (as images

A model for calculating the noise in nonlinear optical processes arising from (nonquantum) stochastic fluctuations (mode beating) in and between the lasers participating in the nonlinear interaction has been previously developed. Assuming that all individual laser mode phases and laser modes are (statistically) independent (Gaussian statistics) and that the nonlinear interaction can be expressed a

Policy intervention schemes for increased deployment of solar photovoltaics (PV) have been launched in several countries, with varying success. In order to ensure an efficient deployment of the technology, thorough knowledge is needed about relevant present actors and institutions, and about how a desirable actor base and institutional setup should look like; mere cost reductions are not enough to

This paper describes and analyzes the strategies and efforts of a public organization in order to establish organizational credibility in multicultural areas. The trust-building efforts by the organization, a local rescue services in the south of Sweden, are a response to several years of social unrest, communicative clashes and hostile treatment between operative firemen and residents in areas of

This paper aims to redress the under-appreciated significance of rent for political ecological analysis. We introduce the notion of value grabbing, defined as the appropriation of (surplus) value through rent. A concept that is analytically distinct from accumulation, rent is both a social relation and a distributional process that is increasingly central to the reproduction of contemporary capita

Background The prevalence of self-reported suicidal ideation, suicide attempts and non-suicidal self-injury (NSSI) remains unclear among adults with autism unrecognised in childhood who attend psychiatric services. Aims We aimed to estimate the prevalence of suicidal ideation, suicide attempts and NSSI; identify factors associated with suicide attempts and NSSI; and describe NSSI in this group. Me

In additive manufacturing, the presence of residual stresses in produced parts is a well-recognized phenomenon. These residual stresses not only elevate the risk of crack formation but also impose limitations on in-service performance. Moreover, it can distort printed parts if released, or in the worst case even cause a build to fail due to collision with the powder scraper. This study introduces

The present study focuses on consuming and producing stories using various forms of expression in the third-grade classroom. The aim of the study is to examine pupils’ and teachers’ experiences of working with a teaching unit that encourages the use of various text and media forms through literary productions, re-presentations, of Ronia, the Robber’s Daughter in order to gain increased insight int

I mål om intrång i förfarandepatent finns särskilda svårigheter med bevisningen. Uppsatsens syfte är därför att utreda bevisproblematiken i mål om förfarandepatentsintrång. Utöver detta ska uppsatsen besvara frågeställningar kring huruvida ett processrättsligt medel kan lösa problemet och även hur man vinner framgång i mål utan att avslöja affärshemligheter. I mål där materialet är ofullständigtIn the case of infringement of method patent there is special difficulty regarding the evidence. The purpose of this essay is therefore to investigate the problem of evidence in cases of infringement of method patent. In addition, the essay is going to answer questions about whether a procedural legal remedy can solve the problem and also if it is possible to achieve success in such a case without

It has been known from multi-zone simulations that HCCI combustion can be significantly affected by temperature stratification of the in-cylinder gas. With the same combustion timing (i.e., crank angles at 50% heat release, denoted as CA50), large temperature stratification tends to prolong the combustion duration and lower down the in-cylinder pressure-rise-rate. With low pressure-rise-rate HCCI

The impact of pH coupled to process design for the conversion of the energy crop Arundo donax to ethanol was assessed in the present study under industrially relevant solids loadings. Two main process strategies were investigated, i.e. the traditional simultaneous saccharification and co-fermentation (SSCF) and a HYBRID design, where a long high temperature enzymatic hydrolysis step was carried ou

This thesis consists of five papers (Papers A-E) treating problems in non-parametric statistics, especially methods of kernel smoothing applied to density estimation for stochastic processes (Papers A-D) and regression analysis (Paper E). A recurrent theme is to, instead of treating highly positively correlated data as ``asymptotically independent'', take advantage of local dependence structures b

Helsingborg, a coastal city in southern Sweden, initiated a long-term redevelopment project called H+ in 2009, aiming to convert industrial harbor space in the city's south into a new, livable urban neighborhood and city center. The project aims to create an open and ‘tolerant city’ in Helsingborg over the next twenty years. In 2010-2011, H+ used an open-source planning method as a strategy to inc

Sedimentological and morphological changes on the upper and lower shoreface during relatively stable sea-level highstand conditions have been investigated in the Pomeranian Bight, southern Baltic Sea, at time scales ranging from storm events to millennia. In order to cover that variety of time scales, different methods have been applied. Seasonal variations in the morphology of the upper shoreface

The aim of the present study is to examine the validity of using silicon semiconductor detectors in degraded electron beams with a broad energy spectrum and a wide angular distribution. A comparison is made with diamond detector measurements, which is the dosimeter considered to give the best results provided that dose rate effects are corrected for. Two-dimensional relative absorbed dose distribu

Global problems such as atmospheric change, acid rain, and water pollution in surface and subsurface environments dominate discussions of world environmental problems. In this thesis the roles of hydrologic processes and hydrogeochemical processes are investigated through development, modification, and application of models for addressing point and non-point source contamination of water. The move

In the early postwar period, improvements in life expectancy in many Western countries made health authorities, health scientists and politicians believe that social differences in mortality converged. The assumption was that inequality, when measured as death rates, was on steady decline, possibly even on the brink of disappearing. The question is then, how far back in time can social differences
