16. Nonmarket Interactions and Density Externalities
Sammanfattning : The four individual papers in this thesis all explore some aspect of the relationship between productivity and the density of economic activity.The first paper (co-authored with Martin Andersson, and Johan Klaesson) establishes the general relationship between regional density and average labor productivity; a relationship that is particularly strong for workers in interactive professions.

17. An ultrasonic density measurement technique : performance, thermal effects, experimental validations, and modeling
Sammanfattning : This licentiate thesis addresses the idea of measurement of the density of liquids using sound. The thesis can be dived into three sections: 1. An introduction that presents the need for the research and its future application into an ultrasonic mass flow meter. 2. LÄS MER
18. On the compression properties of paper - implications for calendering
Sammanfattning : The objective of this work was to study and describe thedeformation of paper in the thickness direction in a calendernip that in some cases was heated. The temperature distributionin the thickness direction was evaluated using modelexperiments. LÄS MER
19. In-situ assessment of timber structures - Assessment methods and case studies
Sammanfattning : In the assessment of timber structures, diagnostic investigations with reference to the condition and structural performance of these structures are necessary and often require appropriate health monitoring techniques. This thesis covers four aspects within the research area of the in-situ assessment of timber structures based on scientific knowledge and guidelines to perform assessment of existing timber structures:IDetermination of density of wood with portable X-rayThe mechanical performance of timber is often strongly related to the density of wood.

20. Planning for emergence: Confronting rule-based and design-based urban development
Sammanfattning : Increasing urban populations, climate changes, financial instability, global conflicts, depletion of resources, and increasing land consumption all contribute to the complex and unpredictable urban challenges we are facing today. A compact urban form is promoted by global and local policies, and research has shown the benefits of dense and diverse properties for their capacity to provide complex responses to complex challenges.
