Anthropometry is a part of physical anthropology, a science that allows the study of measurement methods on the human body and the use of mathematics to analyze the measured results in order to find patterns about human physical development. Measurement of the human body is one of the methods of assessing the general health and nutritional status of an individual or a population.

The purpose of the study is to quantify breast dose to reassure patients and staff that these understandings still apply. A combination of measurements and simulations were used to estimate absorbed breast dose. Gafchromic® XR-QA2 film was used to measure breast dose placed inside the RANDO® phantom in a series of controlled experiments. The RANDO® is an anthropomorphic phantom commonly used for dosimetry investigations. Gafchromic® XR QA2 film is a radiochromic film that changes colour when irradiated. Simulation is commonly used and readily available.

Purpose: The purpose of thesis is to study the influence of temperature, pressure and dopant on the diffusion coefficient and ionic conductivity of the bulk material as CeO2, c-ZrO2, YDC and YSZ. For YDC and YSZ thin films, we find the thickness dependence of the lattice constant, diffusion coefficient and ionic conductivity

Study on hydraulic stability and structural integrity of RAKUNA-IV armour units when randomly placed on the seaward slope of a rubble mound breakwater by means of experiments on physical models in a wave flume and simulations in mathematical models. The results of the research were later applied to a specific breakwater. Recommendations and solutions were thereby put forward for the design, production and construction of RAKUNA-IV armour units when applied to rubble mound breakwaters in reality.

Annals of Mathematics We study the motion of an incompressible perfect liquid body in vacuum. This can be thought of as a model for the motion of the ocean or a star. The free surface moves with the velocity of the liquid and the pressure vanishes on the free surface. This leads to a free boundary problem for Euler’s equations, where the regularity of the boundary enters to highest order. We prove local existence in Sobolev spaces assuming a “physical condition”, related to the fact that the pressure of a fluid has to be positive. ...

It is shown that if a d-regular graph contains s vertices so that the distance between any pair is at least 4k, then its adjacency matrix has at least s eigenvalues which are at least 2pd − 1 cos(  2k ). A similar result has been proved by Friedman using more sophisticated tools.More generally, Serre has shown (see [3], [4] ) that for any fixed r and for any infinite family of d-regular graphs Gi, lim inf r(Gi) 2pd − 1. The same result has been proved by Friedman already in [5].
