In applications spanning from image analysis and speech recognition to energy dissipation in turbulence and time-to failure of fatigued materials, researchers and engineers want to calculate how often a stochastic observable crosses a specific level, such as zero. At first glance this problem looks simple, but it is in fact theoretically very challenging, and therefore few exact results exist. One

The adaptive Least Absolute Shrinkage and Selection Operator (aLASSO) method is an algorithm for simultaneous model selection and parameter estimation with oracle properties. In this work we derive an adaptive LASSO type estimator for diffusion driven stochastic differential equation under weak conditions, specifically that the algorithm does not rely on high frequency properties.All conditional m

The paper deals with domestic hot water circulation (DHWC) in residential buildings. Thermostatic circulation valves (TCV) of self-acting type can be used to assure proper temperature level in DHWC systems. A mathematic model of a DHWC system with TCV's in a 36 flat residential building is presented as well as results from steady-state and dynamic Simulations. The TCV design values used in simulat

In this thesis, the functionality of existing Crazyflie models is extended to include current implementations of attitude and velocity control. The models are validated both as individual agents and as a swarm through comparisons of swarm behaviour during step, ramp and frequency response testing. The models are found to accurately replicate the dynamics of the real system, but additional research

This study aims to examine the Azerbaijan social work students’ views of their professional role in relation to the prevailing environment of an FSU country. The main objective is to identify the students’ views of different key themes; professionalization, identity and knowledge frames of social work to appraise the relevance of these under the development of the profession and in particular for

Following the refugee crisis in 2015, Sweden experienced the largest inflow of refugees in the country’s history. What are the effects on crime of such extensive immigration? This paper aims at analyzing if it prevails a causal relationship between the last years’ refugee immigration and crime rates in Sweden. For this purpose, data from the state’s refugee placement program is evaluated, which yi

In this essay, our aim was to investigate the correlation between deaths due to a terrorist attack an the medial attention of the attack. We do this to test and further expand Virgil Hawkins’ theory about stealth conflicts, where he emphasizes that the most violent conflicts of the world are underreported and in some cases ignored in favor of so-called chosen conflicts, which are on the medial age

Denna kandidatuppsats ämnar undersöka hur förslaget till direktiv om bättre arbetsvillkor för plattformsarbete kommer att påverka korrekt fastställande av sysselsättningsstatus bland plattformsarbetare. Felklassificering av sysselsättningsstatus bland plattformsarbetare har blivit ett allt större problem, med en beräknad fem och en halv miljon människor som på senare tid riskerar att få sin sysselThis thesis seeks to investigate how the proposed Directive on improving working conditions in platform work will affect the classification of employment status among platform workers. The misclassification of employment status among platform workers has become an ever-growing issue, with an estimated five and a half million people being at risk of employment status misclassification as of la

Personlig assistans är en viktig stödinsats för personer med funktionshinder. Två rättsfall på senare tid, HFD 2012 ref. 41 samt HFD 2015 ref. 46, har dock medfört att flera brukare fått sin assistans indragen samt att fler fått avslag på sin ansökan om personlig assistans. Det är domstolens restriktiva tolkning av begreppet grundläggande behov i de två rättsfallen som föranlett denna utveckling.

När en vårdgivare och en vårdtagare saknar ett gemensamt språk att kommunicera på möjliggörs vården först genom översättning av en tolk. För att utforska svenska psykologers erfarenheter av att arbeta med tolk: vilka problem det ger upphov till, om det går att bedriva behandling samt hur de kontextuella faktorerna ser ut på svenska arbetsplatser, gjordes en enkätundersökning. Enkäten besvarades avWhen a clinician and a patient don’t share a language for communication, an interpreter is needed to enable the communication. To explore the experiences of Swedish psychologists of working with a translator a survey were conducted. The aim of the study were to explore which problems arise from working with an interpreter, the possibility of providing psychological treatment and the workplace rout

Skrotning av skepp, även kallat skeppsåtervinning, är en smutsig och farlig industri. Ekonomiska motiv driver skeppsägare att exportera sina icke önskvärda skepp till Asien, där de plockas isär under extremt hälso- och miljöfarliga förutsättningar. Komplexiteten i det sjörättsliga systemet försvårar implementeringen av de juridiska instrument som finns tillgängliga för att förhindra de undermåligaShipbreaking, also referred to as ship recycling, is a dirty and dangerous industry. Economic motives drive shipowners to export their unwanted vessels to Asia, where they are dismantled under conditions extremely hazardous to human health and the environment. The complexity of the maritime system makes it difficult to implement the legal instruments available to prevent the substandard practices,

This thesis regards the study of cellular automata, with an outlook on biological systems. Cellular automata are non-linear discrete mathematical models that are based on simple rules defining the evolution of a cell, depending on its neighborhood. Cellular automata show surprisingly complex behavior, hence these models are used to simulate complex systems where spacial extension and non-linear re

This paper analyses deuteron evaporation in comparison to the evaporation of a proton-neutron pair for different compound nuclei. The main reaction is the fusion-evaporation reaction of 40Ca on 24Mg target leading to the formation of the 64Ge∗ compound nucleus, along with other contamination reactions. The experimental dataset is obtained from Argonne National Laboratory. Projections on γ-γ matric

This paper examines export diversification with main focus on the Economic Community of West African States (ECOWAS), a union promoting economic integration in the region of West Africa. The West African Economic and Monetary Union (WAEMU), another Regional Integration Agreement (RIA), is also of main importance for the study. The study was conducted in order to determine whether ECOWAS and WAEMU,
