2. 1. Analyses of Spur and Helical Gears

   Author : Anette Andersson; Maskinelement; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik; hydraulics; Teknik; Mechanical engineering; Technological sciences; misalignment; contact ratio; load distribution; transmission error; tooth contact analysis;

   Abstract : The thesis contains three papers that comprise studies of the dynamic behaviour of involute spur and helical gears, and one paper that describes a method to determine the influence of misalignment on the static helical gear tooth stress. In the first study, the influence of the contact ratio on the dynamic response of a spur gear was examined. READ MORE

   Abstract : Since the ending of the Cold War, the defence sector, particularly the areas of military logistics and defence acquisition, has been undergoing a comprehensive transformation. There are several factors that explain this transformation: changes in defence and security policies for nations and organisations; reductions in defence expenditure; participation in Peace Support Operations; Lessons Learned from these operations, especially in the area of logistics; revolutionary development in the area of Information and Communication Technology; emergence of novel Commercial Best Practises in the areas of business and business logistics; and changes in the legislation regarding the conduct of public procurement in Europe.

5. 3. Policy Analysis for Different Types of Decision-Making Situations

   Author : Matts Andersson; Svante Mandell; Karin Brundell-Freij; Jonas Eliasson; Lars Hultkrantz; KTH; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; transaction cost; transition cost; misalignment; parking policy; strategic interaction; spillover; resource flow; reference forecast; kilometer tax; minimum parking requirements; Transportvetenskap; Transport Science;

   Abstract : This thesis seeks to contribute to decision support for policy makers in the transport sector. In order to frame the papers and to relate them to the broad field of “policy analysis”, I have structured the papers around a simple framework with three decision levels: responsibility, policy gap, and policy measure.
