This work focuses on observers estimating flux linkage and speed for induction machines, mainly in the low speed region. With speed estimation, sensorless control is possible, meaning that the speed of induction machines without mechanical speed sensors can be controlled. The observer based sensorless drive system has superior dynamic performance compared to a system with an open loop frequency in

The anatomy of the cetrarioid lichens (Parmeliaceae) has been studied, and the taxonomy revised. Special attention has been paid to reproductive structures, in particular the asci and pycnoconidia. Two types of asci are recognized. The Cetraria type is narrowly clavate, bears an amyloid ring structure in the tholus, and has a small axial body. The Lecanora type, specifically the Melanelia form, is

The ECL cells constitute the predominant endocrine cell population of the stomach. They secrete histamine which is a major stimulator of acid secretion. Chormogranin A (CgA)-derived peptides, such as pancreastatin, are co-secreted with histamine. In this thesis it was demonstrated that pancreastatin may serve as a reliable marker for ECL cell secretory activity in the rat. The function of pancreas

Explores elderly and disabled people's travel information requirements when planning a journey by public transport and discusses the potential of information to improve access to the public transport system. Quesionnaire study in order to validate an earlier focus-group interview study about elderly and disabled people's travel information requirements. Results show a need for travel information t

The purpose with this study is to investigate how the verdict against The Pirate Bay is presented in the public room from a normative perspective. My question is within the field – from the courtroom to the public room. The verdict against The Pirate Bay is unique because its relation to the Copyright Act. The defendants have been given review permit to the court of appeal. The debate about file s

Föreliggande uppsats behandlar synen på första världskriget i ett antal konservativa svenska dagstidningar och tidskrifter. Syftet är att undersöka modernitetskritikens roll i de tolkningar av kriget som kom till uttryck i detta sammanhang. Uppsatsens frågeställning tar avstamp i ett tämligen omfattande internationellt forskningsläge, i vilket den anmärkningsvärt höga grad av entusiasm som många e

Because of climate change, rising sea levels in Kristianstad Municipality is more urgent than ever. Sea levels around Scania are estimated to rise more than 2,5 meters in 80 years considering that they are currently rising with 3,2 mm per year. This can lead to erosion and more frequent floods, which in turn can alter beach areas and nearby housing. Kristianstad has an excessive risk of being affe

Uppsatsen utforskar intersektionalitet ur ett rättsligt perspektiv samt ställer frågan om en intersektionell diskrimineringsgrund med beaktande av internationell rätt kan genomföras i den svenska diskrimineringslagen. Inom aktuell socio-legal rättsforskning har en teori om intersektionalitet som organiserat kring noder utvecklats. Teorin används för att identifiera hur intersektionalitet bör imple
