It has been demonstrated that PID controllers can be tuned effectively based on an experiment with relay feedback. This paper describes a tuning method for a general digital controller based on relay feedback. The control design method is based on pole placement. An interesting feature is that the sampling period and the desired closed-loop poles are determined from the experiment. The method is a

Distance relays are one of the most important components of protection available to power system protection engineers. Distance relays can benefit from ideas in the newly developed field of adaptive protection, and can offer an even more selective and sensitive form of protection, under a variety of power system configurations. A new fast adaptive distance protection scheme for single line to grou

Popular Abstract in English At the beginning of 20th century, scientists started to realize that atoms exhibited the discrete behaviour, e.g. the energies of bond electrons were not continuously distributed, but had discrete values. Light is also transmitted as discrete packages (called photons). These phenomena can not be explained by classical physics, which has been accepted as the law of descrThe work presented in this thesis was concerned with investigating the relevant spectroscopic properties of Ce ions randomly doped in an Y2SiO5 crystal at low temperatures (around 4 K), in order to develop a technique and an experimental set-up to detect the fluorescence photons emitted by a single Ce ion. The aim of the work was to determine whether a single Ce ion (referred to as the readout ion

Introduction: In conventional medical linear accelerators, the flattening filter is introduced in the photon beam line to provide a uniform lateral dose profile at a specified depth in water. For some radiotherapy treatments, e.g. intensity modulated radiotherapy, a flat radiation field is not necessary and the flattening filter could be removed. Several studies have shown that removal of the filt

Background: Intra- and interfractional variations in anatomy can cause unplanned substantial alterations of the dose distribution of the target in proton therapy. Motion management methods might be used in order to minimize anatomical variations. In the proton therapy of lung cancer, a potential motion management technique is the use of the voluntary breath-hold approach. The aim of this study was

In this room the climate is tropical with day temperatures between 23–26 °C. During the night, it is only insignificantly cooler. Humidity is high, around 70%. The house got its name because the plant Santa Cruz waterlily, Victoria cruziana, grows in the pond. In addition, a large number of economically significant tropical plants are cultivated here. Giant Granadilla (Passiflora quadrangularis) T

Proteins are large, complex molecules that play many critical roles in the body and are required for the structure, function, and regulation of the body’s tissues and organs. In very simple terms, a protein can be defined as a linear chain of subunits called amino acid residues. The individual amino acid residues are sequentially bonded together by peptide bonds. There are 20 standard amino acids This work is primarily about the development, validation and application of computer simulation models for intrinsically disordered proteins, both in solution and in the presence of uniformly charged, ideal surfaces. The models in question are either coarse-grained or atomistic in nature, and their applications are dependent on the specific purpose of each study. Both, Metropolis Monte Carlo and m

Vi har i detta examensarbete utfört samtidig mätning av värmeutveckling (hydratationshastigheten) och relativ fuktighet (självuttorkningen) hos hydratiserande cement. Denna studie har gjorts på fyra grundrecept med olika cement där vatteninnehållet har varierats för att få olika självuttorkning. Mätningarna av relativ fuktighet är utförda med RF-sensorer som ger utslag i millivolt som därefter omv
