6. Polygonal columns in Greek architecture
Sammanfattning : This thesis studies the use of polygonal columns in Greek architecture from the Geometric to the Hellenistic period. The main purpose of the research is to study the development, distribution, design, function and use of polygonal columns in order to create a new understanding on how they fit in the development of Greek architecture.

7. Modeling of Vertical Shaft Impact Crushers
Sammanfattning : One of the largest products in most civilized societies is concrete used to build various types of constructions. To create this product, a mixture of cement, chemical binders, and rock aggregates are combined and then poured into molds where it hardens. The sand part of the rock aggregates is either from natural sources or manufactured. LÄS MER

9. Femur shaft fractures in children : an epidemiological and biomechanical study
Sammanfattning : Aims: The purpose of this thesis is to describe trends in the epidemiology and treatment of femur shaft fractures in children, to identify risk factors for femur shaft fractures and to compare the stability of various configurations of intramedullary nails to manage these fractures. Background: There are no prior national epidemiologic studies of femur shaft fractures in children. LÄS MER
10. A mechanical model of an axial piston machine
Sammanfattning : A mechanical model of an axial piston-type machine with a so-called wobble plate and Z-shaft mechanism is presented. The overall aim is to design and construct an oil-free piston expander demonstrator as a first step to realizing an advanced and compact small-scale steam engine system. LÄS MER
