Detta examensarbetet handlar om att forma en hemisfäroid från en platt honeycomb-skiva samtidigt som honeycomb-strukturen bibehålls. Honeycomb-strukturen är ett hexagonalt mönster som kan vara gjord av hexagoner, cirklar eller trianglar. Inom kartografi görs jordens sfäriska yta om till en platt representation i form av en karta. Omvandlingen är omöjlig utan förvrängning eller uppdelning i mindreThis Master thesis is about forming a hemispheroid out of a flat honeycomb while retaining the honeycomb structure through an even spread of deformation. The honeycomb structure is a hexagonal structure which can be made out of hexagons, circles or triangles. In cartography the surface of the earth, a spheroid, must be distorted or cut up in order to create a flat map. In the same way forming of

More often than not one would encounter a problem, know that the solution has to meet some requirements, but do not how to start or how to progress towards solving it. Motivation for a computer that can solve the problem automatically without explicitly programming it is apparent, i.e. a computer that \programs itself", is greatly desired. The method of genetic programming has demonstrated it

Thirteen different polymers have been investigated in the tries to find a polymeric water-based binder for the brazing alloy F300. F300 has the chemical formula Fe-24Cr-20Ni-10Cu-7P-5Mn-Si and is a gas-atomized metal powder used for high temperature brazing. Except being water-soluble the polymers used for the binder, would have to provide sufficient viscosity at a maximum 2 wt% and not gel under

The society has always tried to get rid of those who do not "fit in". They doesn't follow the normal behaviour and rules and have to be "dismissed". The community has developed different kinds of institutional care for individuals with dysfunctional behaviour. Those institutions are mental hospitals and prisons. Many of these institutions put the individuals in an extreme s

Uppsatsen behandlar två mycket starka och ibland motstående intressen. Den misstänktes möjlighet att på ett effektivt sätt förbereda sitt försvar genom rätten till insyn i förundersökningen och intresset av en effektiv brottsbekämpning genom skydd för uppgifter om spaningsmetoder. Syftet är att bedöma vad som är en bra avvägning mellan dessa intressen. En fördjupning har gjorts i två särskilda spThe paper deals with two very strong and sometimes conflicting interests. The suspect's right to effectively be able to prepare his defense by having the right to information in the preliminary investigation and the interest of law enforcement agencies’ efficiency in crime-fighting by protection of their surveillance methods. The purpose is to see what a good balance between these two interest

Covid-19 update Due to the increasing spread of COVID 19 in Skåne, the Public Health Agency of Sweden and the Skåne Regional Council have decided on new regulations and general advice for the region of Skåne. The new recommendations are applicable from now until 17 November 2020. No English version is currently available, but in short, they say that you should: avoid commuting with public transpor

The accomplishments of the Nordic Myeloma Study Group (NMSG) during its first 15 yr are briefly surveyed, together with a discussion of principles guiding the group's clinical trials and of problems that need to be addressed in coming years. The group has so far carried out 12 clinical trials, comprising more than 2500 patients, spanning from minor phase II to large randomised phase III trials. At

Men with prostate cancer (n=25) were interviewed, focusing on experiences of micturition problems, indwelling catheter treatment and sexual life consequences. Narrations were found to be practical and technical descriptions rather than emotional, and experiences were described with reduction and negligence regarding personal well-being and the impact of problems. Phenomenological-hermeneutic analy

Current market trends for industrial automation are the need for customizable production, shorter time to market, and powerful global competitive pressure. Based on these trends two challenges have been identified: 1) flexible production systems and 2) integration and utilization of devices and software. Applications from both process automation, manufacturing, and robotics have been considered.

Cold sensitivity is a common and persistent complaint after various hand injuries and diseases. The general aim of the thesis was to investigate the consequences of cold sensitivity for daily life in patients with traumatic hand injuries and hand-arm vibration syndrome (HAVS). To obtain a richer and more comprehensive picture reflecting the aim, studies with a quantitative and a qualitative design

Popular Abstract in French L'inquiétude grandit quant à la perte de la biodiversité liée aux changements d'utilisation des terres, l’effet de cette perte sur les services écosystémiques fournis par les communautés naturelles et semi-naturelles et, finalement, la menace que cela pourrait entraîner sur le bien-être de l’Homme. Ce travail de thèse examine l'impact de l'utilisation des terres présenteConcerns are increasing about the loss of biodiversity under land use change and how this will affect the ecosystem services provided by natural and semi-natural communities and consequently how this will threaten human well-being. The thesis examines the impact of present and past land use on different aspects of biodiversity; namely species diversity, traits and functional diversity and on ecos

Dose calculations for treatment planning of photon beam radiotherapy require a model of the beam to drive the dose calculation models. The beam shaping process involves scattering and filtering that yield radiation components which vary with collimator settings. The necessity to model these components has motivated the development of multisource beam models. We describe and evaluate clinical photo

Biomolecular and pharmaceutical downstream processing is dominated by chromatographic separation, which is associated with high product quality, low capacity and high costs. The separation can be optimized to minimize the costs while achieving a high purity. This paper presents an experimental validation of a discretized multi-level elution (DiME) trajectory, implemented on commercially available

BACKGROUND: Sacroiliac joint pain is increasingly recognized as a cause of low back pain. We compared the safety and effectiveness of minimally invasive sacroiliac joint arthrodesis using triangular titanium implants and conservative management in patients with chronic sacroiliac joint pain. METHODS: This study was a prospective, multicenter randomized controlled trial of adults with chronic sacro

Bark beetles face challenges and trade-offs during host selection, imposed by lethal tree defences, lower nutrition and higher competition in less well-defended trees, scarcity and ephemeral distribution of susceptible hosts, limitation of suitable hosts to one beetle generation, and relatively short lifespan and vulnerability of adults during host searching. Beetles contend with these challenges

The aim of the present paper was to evaluate the possible impact of methacholine challenge on the voice and vocal tract in 10 patients reporting hoarseness due to presumable hyperreactivity to some environmental factors. Ten age and gender-matched healthy subjects served as controls. Methacholine was used for hypersensitivity challenge and saline solution (0.9% NaCl) as control substance. Subjects

Gambling disorder is a major public health issue in many countries. It has been defined as a persistent, recurrent pattern of gambling and is associated with substantial distress or impairment, lower quality of life, and living with a plurality of psychiatric problems. Many people suffering from gambling disorder seek help in ways other than formal treatment seeking, including self-management stra

We discuss the sequence of developments that over the past 90 years led to current insights on heavy-element stability. The semi-empirical mass model, and its extension to deformed shapes, developed in the period 1936–1950 allowed the interpretation of nuclear fission. Around 1950 the spherical single-particle model was developed, soon after with extension to deformed nuclei. Speculations about a

Abstract – Introduction: Stroke is a leading cause of morbidity and mortality globally, with Africa bearing a disproportionately high burden of poor outcomes. In sub-Saharan Africa, acute stroke care remains inconsistent, with organized stroke units being either absent or rarely available, contributing to the high stroke mortality rates in the region. To address this issue, the Tanzania Stroke Pro
