Study on a second-order bandpass Σ∆-modulator for flexible AD-conversion (Electrical/Electronics Project)
An important component in many communication system is the digital to analog converter. The component is needed in order to convert real world analog quantities to digital quantities which are easier to Continue reading
Simultaneous Localization And Mapping in a Marine Environment using Radar Images (Electrical/Electronics Project)
Simultaneous Localization And Mapping (SLAM) is a process of mapping an unknown environment and at the same time keeping track of the position within this map. In this theses, SLAM is performed in a marine Continue reading
Parameter Estimation of Biological Pathways (Electrical Project)
To determine parameter values for models of reactions in the human body, like the glycolysis, good methods of parameter estimation are needed. Those models are often non-linear and estimation of the parameters can be very time consuming if it is Continue reading
Control Strategy in a Centrifugal Separation Process (Electrical Project)
A new concept for separating yeast from beer has been developed at Alfa Laval in Tumba. The yeast is now continuously fed out from the separator instead of discharged when too much yeast have collected in the separator. The concept makes it possible to save beer which otherwise would have been wasted at Continue reading
A Comparison of Circuit Implementations from a Security Perspective (Electrical Project)
In the late 90′s research showed that all circuit implementations were susceptible to power analysis and that this analysis could be used to extract secret information. Further research to counteract this new threat by adding Continue reading
Multivariable feedback control of Electromagnetic Reluctance Force Actuators (Electrical Project)
This study is part of a cooperation between BMW AG and Technische Universitat Munchen, in order to design a road simulator for Squeak and Rattle studies based on Continue reading
Control of a Ground Source Heat Pump using Hybrid Model Predictive Control (Electrical Project)
The study has been conducted at Bosch Thermoteknik AB and its aim is to develop a Model Predictive Control (MPC) controller for a ground source heat pump which minimizes the power consumption while being able to keep the Continue reading
Aspects Of The Choice Of Sampling Frequency In The Control System Of A Gas Turbine (Electrical/Electronics Project)
At Siemens, PLCs are used to control the gas turbines, and to execute the code in the plcs cyclic interrupts are used. If the execution time for the interrupt becomes close to the cyclic time of the interrupt the load of the PLC increases. High load levels can lead to Continue reading
Detection of Driver Unawareness Based on Long and Short-term Analysis of Driver Lane Keeping (Electronics Project)
Many traffic accidents are caused by driver unawareness. This includes fatigue, drowsiness and distraction. In this study two systems are described that could be used to decrease the number of accidents. In the first part of this study a system using long-term information to warn drivers suffering from Continue reading
Space Vector Pulse Width Modulation for Three-Level Converters: a LabVIEW Implementation (Electrical/Electronics Project)
This study explains the theory and implementation of the Space Vector Pulse Width Modulation (SVPWM) using the graphical programming environment LabVIEW as its basis. All renewable energy sources are in need of Continue reading
Particle Filtering for Track Before Detect Applications (Electrical Project)
Integrated tracking and detection, based on unthresholded measurements, also referred to as track before detect (TBD) is a hard nonlinear and non-Gaussian dynamical estimation and detection problem. However, it is a technique that enables the user to track and detect targets that would be Continue reading
Nonlinear Model Predictive Control of the Four Tank Process (Electrical/Electronics Project)
Model predictive control techniques are widely used in the process industry. They are considered methods that give good performance and are able to operate during long periods without almost any intervention. Model predictive control is also the Continue reading
Optimally Fuel Efficient Speed Adaptation (Electronics/Electrical Project)
An optimal velocity trajectory for a heavy duty vehicle, obtained with the aid of modern GPS and digital map devices, depends on several variables. Curvature speed limitations, road grade, and posted road speed are common constraints imposed by the road travelled. This project presents a method for Continue reading
Modeling of the arterial system with an AVD implanted (Electrical/Biomedical Project)
The number of patients that are waiting for heart transplants far exceed the number of available donor hearts. Left Ventricular Assist Devices are mechanical alternatives that can help and are helping several patients. They work by taking blood from the left Continue reading
Asynchronous Wrapper for Globally Asynchronous Locally Synchronous Systems (Electrical/Electronics Project)
This project is investigating the new globally asynchronous locally synchronous (GALS) technology for integrated circuits. Different types of asynchronous wrappers are tested and a new wrapper design is presented. It also investigates the possibility to use Continue reading
Evaluation of Hardware Test Methods for VLSI Systems (Electrical/Electronics Project)
The increasing complexity and decreasing technology feature sizes of electronic designs has caused the challenge of testing to grow over the last decades. The purpose of this project was to evaluate different hardware test methods/approaches based on their applicability in a complex Continue reading
Design of Behavior Classifying and Tracking System with Sonar (Electronics Project)
The domain below the surface in maritime security is hard to monitor with conventional methods, due to the often very noisy environment. In conventional methods the measurements are thresholded in order to distinguish potential targets. This is not always Continue reading
