Purpose: The purpose of this thesis is to develop a simulation model that represents the S-train network. The model will then be analysed in order to improve the regularity. We will then present a locally optimized proposal on the placement of the buffer time for every train line. Delimitation: This report intends only to analyse a ”normal day” during rush hour. We will ignore unexpected course of

The focus of this master’s thesis has been getting a six-legged robot to autonomously navigate around a room with obstacles. To make this possible a time-of-flight camera has been implemented in order to map the environment. Two force sensing resistors were also mounted on the front legs to sense if the legs are in contact with the ground. The information from the sensors together with a path plan

The colorimetric 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay was standardized for direct detection of rifampin-resistant Mycobacterium tuberculosis in sputum samples. The sensitivity and specificity of the direct MTT assay matched those of the standard indirect susceptibility assay on 7H10 medium, and interpretable results were obtained for 98.5% of the samples within

Israel is often referred to as a fragmented state, with the situation between Palestinians and Jews in mind. In Israel however, there are far more fragmentations – even among the Jewish populations. Ethnical differences between Ashkenazi and Mizrahi, religious differences between ultra-orthodox, orthodox and secular, and ideological differences within the Zionist-framework. There is, however, an

None of us are immune to the ongoing identity-processes. Identity formation is something that we are engaged in every day, both in our consciousness and our subconsciousness, from the society levels down to personal levels. This study examines how individuals with Assyrian background form their identities in Sweden. Questions on ”homeland” and ”home”, and statelessness are asked to contribute to t

This project has focused on improving the psychosocial working environment for hospital staff that uses electronic patient records in Region Skåne. Through making qualitative interviews with nurses, doctors and medical secretaries that use patient records on a daily basis I’ve gotten a view of some of the issues with the current system. The problems today seem to be that the documentation system

The role for school curators in issues regarding honours related violent is very complex. There are few studies concerning professional experience of management in matters of honour related violent. The purpose of this paper is to examine how the professional school curator's role is described in honour violent cases. Furthermore, focus has been put on highlight the school counselor’s interact

This thesis is a journey of dissent, an exploration of the counter-movements against the business-as-usual illustrated by the means of food. It relates my intense odyssey as student dealing with her own research process while diving into the fabulous tasty realm of food resistance. I aim through my words to demonstrate the significant potential of food as an instrument of dissent, of resistance ag

This thesis deals with animal bones from the medieval town of Viljandi. My aim is to study the consumption of different species and possible spatial, temporal and social differences thereof. Bone assemblages from Viljandi’s suburb, town and castle area are analyzed with osteological, quantificative and statistical methods. Most of the consumed species in the town have been cattle, sheep, goat an

Many surface science experiments within heterogeneous catalysis are now conducted in realistic conditions at higher pressures. At these pressures, localized gas conditions will form throughout the reactor. Understanding these gas conditions and their interaction with the catalyst surface at relevant time scales and with spatial resolution is important. To address this issue, we use a combination o

The food sector is currently very inefficient due to a large amount of food waste it generates, and the volumes of water and energy used. This problem is aggravated by increasing economic costs and stricter regulations associated with the disposal and treatment of food waste, carbon emissions and wastewater discharge. Because of this, resource efficiency is key to a sustainable food system. In thi

Predator avoidance behaviour costs time, energy and opportunities, and prey animals need to balance these costs with the risk of predation. The necessary decisions to strike this balance are often based on information that is inherently imperfect and incomplete due to the limited sensory capabilities of prey animals. Our knowledge, however, about how prey animals solve the challenging task of rest

This work presents an event-based control structure using the generalized predictive control (GPC) algorithm with actuator deadband. The main objective of this work is to limit the number of controlled system updates. In this approach, the controlled process is sampled with a constant sampling time and is updated in an asynchronous way that depends on the obtained control signal value. To achieve

Abstract in UndeterminedRecording eye movement data with high quality is often a prerequisite for producing valid and replicable results and for drawing well-founded conclusions about the oculomotor system. Today, many aspects of data quality are often informally discussed among researchers but are very seldom measured, quantified, and reported. Here we systematically investigated how the calibrat

Several extensions of the Standard Model predict the production of dark matter particles at the LHC. A search for dark matter particles produced in association with a dark Higgs boson decaying into W+ W− in the ℓ±νqq¯′, final states with ℓ = e, μ is presented. This analysis uses 139 fb −1 of pp collisions recorded by the ATLAS detector at a centre-of-mass energy of 13 TeV. The W± → qq′ ¯ decays ar

We have for the first time identified the early stellar disk in the Milky Way by using a combination of elemental abundances and kinematics. Using data from APOGEE DR17 and Gaia we select stars in the Mg–Mn–Al–Fe plane with elemental abundances indicative of an accreted origin and find stars with both halo-like and disk-like kinematics. The stars with halo-like kinematics lie along a lower sequenc
