The purpose with mathematical models in ecology is 1) to help to create better understanding of ecological systems behaviour and 2) to make it possible to estimate more accurately the effects of human interference in nature.

This paper deals with optimal long-distance steering of large vessels. The purpose of the paper is to design a regulator, that keeps a vessel, when affected by different disturbances, on an economical course. The vessel is supposed to have constant speed forward and therefore the only steering variable is the rudder angle. From a mathematical model of the vessel, the equations of motion are calcul

Measurements of a room have been done at the institution Byggnadskonstruktionslära, and I would like to thank the institution and especially Kurt Källblad for the help.
Measurements have been done at three different warming types, radiant-, convective- and radiator warming.
I have two inputs. One is the temperature of the heating apparatus, and the other one the outdoor temperature. The

This paper deals with the construction of an interface which is to be placed between a process and a Process Computer.
The interface shall integrate the process signal during a period which is a multiple of the period of the line-frequency. This means that the disturbance from line-frequency will be completely eliminated.
The process signal is also to be transformed to the 0-+-10

In this work, which is to be used as a supplementary example to the educational literature in Automatic Control, at LTH, I have chosen one reactor, in the group of chemical reactors, for the examination. The chosen reactor is the continuos-flow, autothermic, nonadiabatic stirred-tank reactor. Required cooling of the reaction mixture is achieved by letting the reactor-tank be surrounded by a coolin
