Automatic Determination of Parameters in Dynamic Load Models from Normal Operation Data

Various parameters in dynamic load models were determined from the normal operation data. Steady state load-voltage dependence, transient load-voltage dependence and a load recovery time constant parameters were chosen for the study. It was observed that large variability in voltage was due to high diversity of load processes. It was also observed that transient reactive load-voltage dependence wa

En afton på Röda Kvarn. Svensk stumfilm som musikdrama

The dissertation delineates the development of silent film music in Sweden in relation to changes in the production practices. Also, the study shows, through analyses of certain Swedish films from 1919-1928, that music to narrative silent film had and still has a dramaturgical, structural, narrative and dramatical function which has to be taken into consideration when one studies the reception of

Implementation of MRI gel dosimetry in radiation therapy

Popular Abstract in Swedish Gel-dosmätningar för kontroll av strålbehandling av cancertumörer När en patient strålbehandlas avser man att bestråla sjuka områden i kroppen. Det är dock omöjligt att göra detta utan att därmed även till viss del stråla på omkringliggande organ och komplikationer kan då uppstå. För att minimera dessa bieffekter och optimera behandlingen används ofta en så kallad dospGel dosimetry was used together with magnetic resonance imaging (MRI) to measure three-dimensional absorbed dose distributions in radiation therapy. Two different dosimeters were studied: ferrous- and monomer gel, based on the principles of radiation-induced oxidation and polymerisation, respectively. Single clinical electron and photon beams were evaluated and gel dose distributions were mainly w

On the Dimension of Iterated Sumsets

Let A be a subset of the real line. We study the fractal dimensions of the k-fold iterated sumsets kA, defined as kA = {a(1) ... + a(k) : a(i) is an element of A}. We show that for any nondecreasing sequence {alpha(k)}(k=1)(infinity) taking values in [0,1], there exists a compact set A such that kA has Hausdorff dimension ak for all k >= 1. We also show how to control various kinds of dimensions s

Lekmannens plats i kyrkan

The chapter emphasizes the historical position of the layman in the Church of Sweden as an independent complement to women and clergymen. Spiritual letters, funeral sermons, and fictional material are used as sources. During the nineteenth century the Christian layman was professionalised or specialised in a way that did marginalize him as the layman as such.

Cost-effectiveness of prophylaxis against on-demand treatment in boys with severe hemophilia A in Iran.

Objective: The aim of this study was to assess the incremental cost-effectiveness of on-demand versus prophylactic hemophilia therapy in Iran from a third-party payers’ perspective.Methods: A retrospective chart review of twenty-five type A hemophiliacs who were treated in three hemophilia treatment centers was conducted. The patients were boys 0–9 years old receiving one of two treatments: (i) pr

Sex in Big-Character Posters from China's Cultural Revolution : Gendering the Class Enemy

As a defining component of the Cultural Revolution, the “dictatorship of the masses” did away with constraints that had previously kept the most private of the private parts of Chinese people’s lives out of the political arena. In the years 1966–1969, in particular, discursive strands that did not shy away from the topic of sex in politics and revolution proliferated. This paper comments on some r

Transdisciplinarity in rammed earth construction for contemporary practice

Abstract in UndeterminedFor centuries rammed earth has been a method of construction in various parts of the world. It is an economical building technique as earth is an abundant cheap resource. It is durable, safe and a desirable building technique for hot climates. This paper is discussing a workshop activity in building with sustainable rammed earth construction methods in Egypt. It adds to pre

Machinability of Ductile Single-Phase Materials Used in Accelerator Components - A Study with Focus on Surface Integrity

The focus of this article has been to analyse the machinability, with focus on surface integrity, of oxygen-free copper (OFC) and niobium during turning operations. The results from machining OFC proved that all of the tools that was tested can be used to achieve a surface roughness below Ra = 0.8 µm with the correct cutting data. From the results when machining niobium it showed that only the cem
