In industrial control systems PID-control remains the prevalent strategy, also for processes that would benefit from model based control. The purpose of this thesis is to evaluate whether model based control can be readily implemented in an industrial control system. To this end …
Linux is a growing operating system in embedded systems. Today, Linux is not only in heavy servers but also in cell phones, PDAs, cameras and other devices running on battery power. While current technology is more energy efficient, more and more technologies are implemented …
During installation and operation of a geothermal heat pump system leakage of an antifreezing agent can appear in a borehole and leak out in surrounding groundwater. To guarantee high quality drinking water for generations to come Sweden has dedicated some areas as water …
… days dependent on reliable, efficient and user-friendly computer-based support systems. This study is an evaluation of Holmen Skog's current computer-based systems. The aim of this study is to: ” investigate the work pattern of the production managers when using the information …
… of up to 1000 tons. For the generator and turbine to work well the rotating system is required to be centered in relation to the surrounding structure. This is achieved by means of radial bearings. The dynamic characteristics of these bearings have a strong impact on the overall …
… of the subject field history of medicine. The two classification systems SAB and NLM are compared in order to find out which one is the most adequate to organize a small collection of history of medicine. SAB and NLM are the two most commonly used classification systems in …
… which has been developed to find leaks in the fuel tank and evaporation system. According to the OBD II requirements leaks with an orifice diameter larger or equal to 0,5 mm, must be detected. The idea of the diagnosis method is to create an over pressure in the system with an …
Most often when developing a new system there is a need get a functioning testtool up and running. Including time, cost and resources the solution isn’t always obvious, developing your own or buy one ”of the shelf”. The purpose of this thesis is to study how a general testtool …
… In response to these thoughts I began to investigate what alternative school system might provide more flexibility and choice for students. The alternative school system that appears to have the potential to effectively address the concerns raised above emerged in Sweden, in the …
The project, Flexible Snowboard System, has been carried out by the project group independently and is a module developed for snowboarders, ski rentals and ski schools. The problems of today’s solutions are that they cause the user an inconvenient standing position when riding …
… ett koncept och en prototyp till ett Computer SupportedCooperative Work (CSCW) system, utvecklat av Elof Dimenäs och Mats Sundgren(AstraZeneca) i samarbete med IT-universitetet. Systemet ska stödja interaktion med patienteri effektstudier och att övervaka medicineringen och dess …
… to predict how lameness changes when the horse is ridden. Recently, a system to objectively detect lameness has been developed. This system, called ”Lameness Locator”, is based on a combined accelerometer- and gyroscope- technique. This technique analyzes asymmetric movements of …
En bedömning av acceptabilitet och tonkvalitetsuppfattning
This thesis presents an adaptive tuning system that can be described as a dynamic Just Intonation tuning system, being compatible with equally tempered instruments. The tuning system is called Hermode Tuning (HMT) and the tuning used as comparison for evaluation is the …
… cells are connected with a power inverter to form a power providing system. To approach the issue an analysis of three main areas is made. Primarily the photovoltaic system is sized based on the electricity consumption in the buildings. Furthermore an assessment is made whether …
… by a network of networks where decision-makers, information- and weapon-systems are linked together. As a part of the development of NBD, we have performed a study of user interface design for a future network-based tool package for analysis of sensor systems, referred to as the …
