Communication delays in real time systems cause detoriation of the control performance of the closed loop system. To investigate this problem a process with varying delay is studied. Control of a motor in presence of delays is studied for different delay models. Design equations are derived based on polynomial design. The design depends on the designer's choices, i.e. desired closed-loop behav

In this report the setting of parameters for the stabilizers in power systems are discussed. This tuning should be done in a systematic way, and the method proposed here is based on optimization. Different problem formulations involving settling times, stabilizer gains, damping and rise time are used.

Different models of heat load in a district heating system at Karlstad have been tested. The input of the model contains one climatic dependent part and a profile which depends on time. The climatic inputs are outdoor temperature, solar intensity and wind velocity. The profile tries to describe the consumption of hot water. This model has later been used to predict the heat load for one or a few h

Logical control of a model railway is presented. The model railway is controlled by a PDP 8/s minicomputer. By energizing tracksections and switching turnouts the trains can be controlled.

Människor begår ofta brott tillsammans med andra. Denna uppsats handlar om hur gränsdragning mellan framförallt medgärningsmannaskap och medhjälp och den problematik som de otydliga gränserna medför. Syftet med detta arbete är att undersöka rättstillämpningen under det senaste decenniet vad gäller gränsdragningsproblematiken mellan medverkansformen medhjälp och termen medgärningsmannaskap. YtterliPeople often commit crimes together. The thesis discusses the problems connected to the flexible laws within the complicity area of Swedish penal law. The focus being the demarcation between being charged as a “co-party perpetrator” or being charged with complicity. The purpose of the essay is to discuss relevant cases in relation to the above- mentioned demarcation problems. In addition to this,

Uppsatsen undersöker hur Dublinförordningen förhåller sig till Europakonventionen, med fokus på artikel 8 om rätten till respekt för privatliv, familjeliv, hem och korrespondens. Dublinförordningen är det instrument i EU:s gemensamma asylsystem som bestämmer vilken medlemsstat som ska ansvara för att pröva en inkommen asylansökan. På senare år har mycket kritik riktats mot Dublinförordningen p.g.aThe essay examines how the Dublin Regulation relates to the European Convention on human rights, focusing on Article 8 on the right to respect for privacy, family life, home and correspondence. The Dublin Regulation is the instrument of the EU's Common Asylum System, which determines which Member State will be responsible for examining an asylum application. In recent years, much criticism has

Technological advancements cause it to be more common for managers and subordinates to work together from different geographical locations. It is associated with challenges, which virtual leadership is supposed to support in overcoming. As the leader is central in studies on virtual leadership, this qualitative study takes a different perspective and has as its purpose to understand how leadership
