1. Experimental and computational investigation of the roll forming process
Sammanfattning : One of the first questions to consider when designing a new roll forming line is the number of forming steps required to produce a profile. The number depends on material properties, the cross-section geometry and tolerance requirements, but the tool designer also wants to minimize the number of forming steps in order to reduce the investment costs for the customer.

3. Modelling and simulation of the roll forming process
Sammanfattning : One of the first decisions to make when a new roll forming line is designed is the number of forming steps needed to produce a profile. This is dependent on the material properties, the cross-section geometry and the tolerance requirements. LÄS MER
4. Glory and failure : The difference engines of Johann Müller, Charles Babbage and Georg and Edvard Scheutz
Sammanfattning : This book presents a social and technical analysis of the first attempts to mechanize the production of numerical tablets. It deals with an age when the word "computer" denoted a human being and not a machine. LÄS MER
5. Modeling and Control of Voltage Source Converters Connected to the Grid
Sammanfattning : This thesis deals with the modeling and control of pulse width modulated (PWM) voltage source converters connected to the grid. When voltage source converters are connected to the grid, the power quality and the dynamic performance are affected by the line filter connected between the converter and the grid, and by nonlinearities caused by the switching converter.
