Many important problems involving a group of unmanned ground vehicles (UGVs) are closely related to the multi traviling salesman problem (m-TSP). This paper comprises a comparative study of a number of algorithms proposed in the litterature to solve m-TSPs occuring in robotics. The investigated algoritms include two mixed integer linear programming (MILP) formulations, a market based approach (MA)

We present novel developments for the highly efficient evaluation of complex linear response functions of a multiconfigurational self-consistent field (MCSCF) wave function as implemented in MultiPsi. Specifically, expressions for the direct evaluation of linear response properties at given frequencies using the complex polarization propagator (CPP) approach have been implemented, within both the

This study investigates the relationship between changes in the frequency of dwell time delays and passenger flow characteristics and the frequency of railway service during the COVID-19 pandemic. To do so we make use of automatic passenger count data from commuter trains in Southern Sweden. Our findings show that the frequency of dwell time delays decreased under COVID-19 conditions compared to t

Urbanisation is one of the biggest environmental challenges of our time, yet we still lack an integrative understanding of how cities affect behaviour, physiology and parasite susceptibility of free-living organisms. In this study, we focus on carotenoids, strictly dietary micronutrients that can either be used as yellow-red pigments, for integument colouration (signalling function), or as antioxi

Background: Lumbar puncture (LP) is a common invasive procedure, most frequently performed to diagnose infection. Physicians perform LP in newborn infants with the help of an assistant using a strict aseptic technique; it is important to monitor the infant during all the steps of the procedure. Without adequate analgesia, LP can cause considerable pain and discomfort. As newborns have increased se

We investigate a means of explaining the apparent paucity of red giantstars within post-core-collapse globular clusters. We propose thatcollisions between the red giants and binary systems can lead to thedestruction of some proportion of the red giant population, by eitherknocking out the core of the red giant or by forming a common envelopesystem which will lead to the dissipation of the red gian

Due to organizational changes in the Swedish air navigation services (ANS), which in extension could impact flight safety, the safety culture (SC), organizational climate (OC), and related areas are monitored. Study locations are the two main air traffic control centers in Sweden and parts of the central ANS office. This paper reports on a first attempt to investigate whether relationships exist b

Hordein, the seed storage protein in barley, is encoded by a multigene family. All wild and cultivated species of the Hordeum genus were investigated electrophoretically and imunologically for their hordein composition. The reactions of specific monoclonal antibodies showed that particular polypeptide regions have been conserved throughout the genus. Some of the regions could also be recognize in

This article outlines a number of new approaches in the history of medicine and medical humanities to the study of medical case histories from a genre-theoretical vantage point. Differentiating between morphological and structuralist concepts of genre, the essay proposes the investigation of similarities and differences among specific series of case histories in order to recover evolving, changing

Background: The ability of modern ultrasound machines to detect signs of enthesitis has increased, yet there is a lack of studies on patients with long-standing radiographic axial spondyloarthritis (r-axSpA). Hence, we aimed to investigate the prevalence and clinical significance of Doppler signals indicative of inflammation in peripheral entheses of patients with long-standing disease. Methods: P

Plats Hus Människa: En berättelse är ett examensarbete i arkitektur som redovisar ett byggprojekt på djupet, från den första inspirationen till ett förverkligande i full skala. När man försöker gestalta en sådan komplex process gäller det att begränsa sig genom att ha tydliga ramar. För min egen del så innebär det att jag konsekvent har utgått från en viss skola inom arkitekturen och att jag både Plats Hus Människa: En berättelse (Place House Person: A story) is a master thesis in architecture that describes a project from start to near completion in full scale. Since my personal relation to the site is strong, my point of departure is the phenomenological architecture. This architectural movement emphasizes the importance of place. The main tool of both my investigation of place and my pr

I 29 kap. 6 § BrB regleras förutsättningarna för påföljdseftergift. Bestämmelsen har tre kumulativa rekvisit: att den tilltalade har funnits skyldig till brottet, att det finns förmildrande omständigheter samt att en påföljd framstår som uppenbart oskälig. De förmildrande omständigheterna i 29 kap. 5 § BrB, som påföljdseftergift grundas på, kallas ”billighetsskäl” och hänför sig till omständigheteThe prerequisites for remission of sanctions are regulated in chapter 29, 6 § of the Swedish penal code (BrB). The regulation has three cumulative prerequisites: that the defendant has been found guilty, that there are mitigating circumstances and that a sanction, with regard to these circumstances, is obviously unreasonable. The mitigating circumstances, that are regulated in chapter 29, 5 § BrB,

Syftet med detta arbete är att kritiskt diskutera beviskrav och bevisbörda i dispositiva tvistemål i svensk rätt de lege feranda. Det nu rådande beviskravet i tvistemål anses vara styrkt eller visat, vilket innebär ett relativt högt sannolikhetskrav. Gällande vad som är den rådande huvudregeln för bevisbörda råder, oenighet inom doktrinen där många olika teorier florerar. I arbetet föreslås en ny The purpose of this study is to discuss probability threshold and the burden of proof in dispositive litigation in Swedish law de lege feranda. The current evidentiary requirement in civil cases is considered to be proven or proven, which means a relatively high probability requirement. Regarding what is the prevailing main rule for the burden of proof prevails, disagreement within the doctrine wh

This thesis addresses overvoltage issues in weak low voltage grids caused by large solar power production. The suggested method is using PI controllers to control voltage. This is done by using battery energy storage systems (BESS), designed to absorb active power during these times and thereby limiting the voltage rise. This could enable faster integration of solar power and a reduced demand for
