1. Further Developing Preload Lists for the Tor Network
Kandidat-uppsats, Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)Sammanfattning : A recently proposed defense for the anonymity network Tor uses preload lists of domains to determine what should be cached in the Domain Name System (DNS) caches of Tor relays. The defense protects against attacks that infer what is cached in Tor relays. LÄS MER
2. Modelling of a Glued Bolt Joint in Finite Element
Master-uppsats, KTH/HållfasthetsläraSammanfattning : This report presents a master thesis project at KTH at the school of Engineering Science. The project is done in collaboration with ABB Robotics, a company who develops industrial robots. A robot consists of several parts and the last structural part is the wrist. LÄS MER
3. Classification of ultrasonic signals using machine learning to identify optimal frequency for elongation control : Threaded fastening tools
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Studying the preload in a screw joint has been the focus of today’s industry. The manufacturer reflects that demand by investigating different opportunities and techniques to develop this area. There are four different ways of controlling the tightening of bolts and joints to achieve the required clamp force that can hold for a specific preload. LÄS MER
4. Identification of Potential Sources of Measurement Errors in an Isokinetic Dynamometer : Reliability Analysis of Shoulder Abduction and Flexion Data
Kandidat-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : The evaluation of shoulder abduction and flexion strength is important in the rehabilitation after rotator cuff tear. The purpose of this work is to assess the intra and inter-rater reliability of measurement data from an isokinetic dynamometer used to evaluate shoulder abduction and flexion strength, with the aim to identify sources of measurement errors and suggest improvements.

5. Simulation of ultrasonic time of flight in bolted joints
Master-uppsats, KTH/HållfasthetsläraSammanfattning : Ultrasonic measurements of the preload in bolted joints is a very accurate method since it does not depend on the friction and other factors which cause difficulties for common methods. The ultrasonic method works by emitting an ultrasonic pulse into the bolt which is reflected at the end and returned to the transducer, the change in the time of flight (TOF) can be related to the elongation of the bolt and therefore the preload.
