In this paper a new Space Vector Pulse Width Modulation method is proposed for multilevel voltage source inverters. This method is based on Space Vector Modulation and is compared to other similar methods. According to the method presented the multiplicity of the switching states of a multilevel inverter is also considered. This means that the new pulse method takes into account the multiplicity o
Cytochrome c oxidase is an essential component of the mitochondrial respiratory chain that catalyzes the reduction of molecular oxygen by reduced cytochrome c. In this study, the authors report the second mutation associated with Leigh syndrome in the blood and buccal mucosa of 2 affected members of a Tunisian family. It was a novel heteroplasmic missense mitochondrial mutation at nucleotide 9478
In this study, bread was baked with and without the addition of α-amylase. Starch was extracted from the baked bread and its molecular properties were characterized using 1H NMR and asymmetric flow field-flow fractionation (AF4) connected to multi-angle light scattering (MALS) and other detectors. The approach allows determination of molar mass, root- mean-square radius and apparent density as wel
Though many individual transcription factors are known to regulate hematopoietic differentiation, major aspects of the global architecture of hematopoiesis remain unknown. Here, we profiled gene expression in 38 distinct purified populations of human hematopoietic cells and used probabilistic models of gene expression and analysis of cis-elements in gene promoters to decipher the general organizat
This research discusses the importance of a photograph of an accused war criminal, Abdul Kader Molla, during the period immediately before the emergence of the Shahbag movement in Bangladesh. The image captures Kader Molla flashing a V sign, and it was taken in the moments after he had been sentenced to life imprisonment by the International Crimes Tribunal in Bangladesh in 2013. After Kader Molla
A major obstacle in ex vivo gene transfer has been the loss of transgene expression soon after implantation of the grafted transduced cells. Recently, a lentiviral vector system has been developed which has proven to express high levels of transgenes in vivo after direct injection into the tissue. In this study, we have investigated the use of such a vector for ex vivo gene transfer to the brain.
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.
This thesis aims to investigate the accuracy of Value-at-Risk and Expected Shortfall forecasts of various GARCH-type models based on five currency exchange rate pairs. The GARCH models are employed under different conditional distributional assumptions, and extended using the two-stage Extreme Value Theory (EVT) approach of McNeil and Frey (2000). The forecasts are evaluated through simulation usi
