This report of master thesis describes two programming languages for micro processors namely: MLP for Intel 8008 developed at CERL, Great Britain and HILP 80 for Intel 8080 developed as master thesis at Lund Institute of Technology. The compilers generate assembly code and are intended to be implemented on a host computer. The compilers are based on the macro processor STAGE 2, and need about 15 K

This report provides results of simulations and a few different methods of designing controllers for sampled data systems.

In the report a mathematical model of the exhaust nozzle control of a turbofan engine is shown. During the simulations great attention has been paid to the sensitivity of the regulators against variations of the parameters in the system, and the behaviour of control s

The goal of this work is to build a dynamic model for a steam power plant, using frequency and step-response analysis and use it for construction of an automatic controlling system. The model is to simulate all the variables necessary for controlling with reasonable accuracy.

By using measurements at a power plant in x 14rebro, the transfer functions for the most important steam pressures

Kockums Mekaniska Verkstad, Malmö, is building a submarine rescue vehicle (URF) for military and civilian purposes. The theoretical and experimental background for the dynamics of the submarine is incomplete. One miss is for example a total model for the submarine, that is, what happens when you pull the control lever. We have constructed such a model suitable for simulations on a computer in the

Our task has been to design a dynamic model for a super heater of a marine steam boiler on a turbine vessel. We have also investigated different methods for control of the temperature of the outflowing steam by computer simulation. The aim has been to make the regulation faster at different load and disturbance.

In our models we have described characteristics for valves, regulators and st

A simple flight simulator has been built up, using an analog computer to simulate the aircraft dynamics.
The dynamics model used, does not represent any particular aircraft. It is nevertheless representative of a large group of conventional aircraft. Simulations clearly show an increased ease in handling the flight simulator, if the pilot has flying experience. This indicates a similarity betw

In this paper I examine what I call the ‘gnomic expression’, i.e. a statement of a general truth with regards to the human condition, as it is manifested in the Iliad, the Odyssey and Beowulf. A general introduction is first given to gnomic poetry in the Greek and Anglosaxon traditions in order to put the main analysis into its historical and literary context. The analysis is then presented in fiv

Som sångerska har jag sjungt en hel del i kör, och på grund av det har jag fått möte flertalet körledare. Dessa körledare har olika kunskaper om rösten, och har lärt mig om rösten på olika sätt. Ibland var det felaktig information som delgavs, ibland var det ordvalen som kunde varit bättre, och ibland hade körledaren full koll. Den kunskap som körledarna förmedlar formar sedan koristerna, och då s

The study explores how USA, as a liberal democracy, justifies actions that can be described as extra-judicial targeted killings. The study is based on a three-case study of the Clinton, W. Bush and Obama administrations. The frame theory is used to categories and analyze the official statements, to get an understanding of how the different presidential administrations with the use of words are try

We develop methods for estimation, inference and optimization of causal effects from observational data with continuous treatments. We present a counterfactual prediction method based on the potential outcomes framework that estimates the expected value of a potential outcome given a treatment level and confounders. We show that the method identifies the average generalized treatment effect (AGTE)

När jag under min utbildning varit ute på praktik och vikarierat har jag flera gånger stött på begreppet konstnärligt uttryck. Jag har alltid tyckt det var svårt att förstå exakt vad ett konstnärligt uttryck innebär. Därför föddes idén till denna studie om att prata med verksamma sånglärare inom gymnasieskolan och ta reda på mer om hur de jobbar med det konstnärliga uttrycket. Syftet med denna stu

The riparian countries of Lake Chad River Basin – Nigeria, Niger, Cameroon and Chad – suffer from environmental degradation as the lakes surface water has decreased with 90 percent since the 1960’s. This has put pressure on the population around the lake as the livelihood for many of them is dependent of the lake’s water. The area has during the last decade also been characterized by increased vio
