… to an automatic milking machine from DeLaval is investigated. The robot arm is controlled by a pneumatic cylinder and a valve. The goal of the master thesis is to investigate instability problems and to find out if it is possible to solve them by using gain scheduling. Gain …
A helicopter based system equipped with a millimetre-wave fire control radar is studied for improvement of the detection probability for moving ground targets. The system is a pulse doppler radar that sends out the electromagnetic wave in repetitive pulses. The frequency in …
… features described include a generalized interaction layer providing greater control to artists, a new way of dealing with moving objects that interact with the fluid and a method for adding source and drain capabilities.
… of time per day. The conclusion is that a stationary system with a computer controlled and rail carried mixer fulfils the two goals under the condition that a new cattle shed for the heifers are built nearby the existing cowshed, which is planned.

… methods of drying clover grass with an Elho TR220 (tedder). One windrow is control there I didn’t do anything. With the second method I drove the Elho machine after 18 h. The last method I drove the Elho twice, 18 h and 39 h after cutting. Every treatment repeated 12 times. I …
… system which purpose is to make the model to behave like a real tower in control application, although it only has half the inertia as a real tower. The thesis even includes proposing a calculation of the torque that the torque generating system will actuate at the model.
… are facing new challenges when it comes to improving the engines and the control software. Accurate and real time executable engine models are essential in this work. One successful way of lowering the NOx emissions is to use Exhaust Gas Recirculation (EGR). The objective of …

… av Tommy Efraimsson i LDS, LUCS design system. LUCS står för LHD-underground-control-system där LHD är en beteckning för typen av lastmaskin, load-hoaul-dump. Mats Strömsten har utifrån de parametrarna sedan beräknat tidsvinsten i Excel. Våra beräkningar är baserade på tiden för …
… som satts upp och samtidigt beskriva utvecklingsarbetet av ett datoriserat system för att hantera bokningar och för SMS-notifiering. De frågeställningar som, i denna rapport, besvaras är: 1. Går det att skapa ett datoriserat bokningssystem som bidrar till att Bärarelagets …
… risk and change within these kinds of projects in order to prevent and avoid uncontrolled changes. Our purpose with this thesis is to investigate if change is a problem in IT-projects. Thereafter we identify and examine procedures to avoid uncontrolled changes within IT-projects …

… not the queue-times that is the biggest problem. The problem is the shop floor control and the lack of manufacturing the right products at the right time. Therefore an analysis of the production planning process was made to bring forward the real problems. The purpose of this …
… that this diluter can handle. Therefore another modification is proposed for controlling the inlet exhaust flow so it will be possible to regulate the dilution ratio and make it constant along a wide range of engine loads and speeds. The second and most important stage was to …
… aim of the development of Telfafill is to separate the user interface from the control unit. In addition to this main objective, Telfafill AB would like possible changes to, and additions of, functionality of the filling machine to be investigated. Within the boundaries of this …
… is based either on blocking the nociceptores or on the body’s own pain controling system. Analgesic drugs act in various ways on the peripheral and central nervous systems. Peripheral working analgetica has effect on pain and inflammations in a limited area (nociceptive pain) …
An automatic milking (AM) system should be combined with some form of controlled cow traffic to minimize the time spend on fetching cows to milking and to increase the milking frequency. By restricting the hours spent on pasture per day you optimise the AM system use during …
