21. Measurement and prediction of outcome. Application in fusion surgery for chronic low backpain. The Swedish lumbar spine study
Sammanfattning : Background: Outcome of surgery for chronic low back pain should be documented ina standardised and reproducible fashion to establish evidence of its benefit. Measurement of outcome requires validated instruments, which have the ability to detect functionalchanges perceived as beneficial by the patient. LÄS MER
22. The interdependence of plastic behaviour and final properties of steel wire, analysed by the finite element method
Sammanfattning : The finite element method (FEM) has been used in order to study the interdependence of plastic behaviour and final properties in steel wire. Three processes metal forming have been studied: billet forging, wire rod rolling, and cold drawing. LÄS MER
23. Dynamiskt belastade tribologiska system under plastisk formning, del II --- analyserade genom akustisk emission
Sammanfattning : The dynamic friction process and contact surface between tool and working material in a plastic forming process is hard to describe in mathematical form and hard to monitor and control in real time. High production speed and highly optimised forming operations result in great demands on the control equipment. LÄS MER
24. 3-D Forming of Paper Materials
Sammanfattning : Paper materials have a long history of use as a packaging material, although traditional paper-based packaging is limited in its shape, complexity, and design. In order to better understand the deformation and failure mechanisms during 3-D forming, two experimental studies of paper materials have been conducted. LÄS MER
25. The Invisible Tools of a Timber Framer - A survey of principles, situations and procedures for marking
Sammanfattning : My thesis focuses on the marking procedures when building timber frames, from the idea of a construction to the cutting of the timbers. The marking procedures are essential parts of the building process, and without markings you don’t know where to cut. LÄS MER
