The aim of this thesis was to investigate and characterise the effect on electron dosimetry that localising different forms of bolus, both approximately tissue equivalent and non tissue equivalent, in a non conventional, although reproducible locations, (ie not on the phantom surface). A series of experiments were derived to compare the differences in beam characteristics between the recognised conventional method of locating bolus on the surface to that of bolus supported by the Low Melting point Attenuator (LMA) Electron insert.

This thesis has two key results, a study on the effect of carbon in electron-beam deposited platinum nano-wires and a novel temperature sensing glass substrate for marker-free thermometry. The thesis focus on the effect of carbon contamination in plasmonic nano-wires composed mainly of platinum produced from FEBID. Because carbon acts as an insulator in the platinum/carbon composite, we model the effect of carbon impurities by reducing the charge carrier concentration inthe platinumwire.

Target of thesis: To develop a method that can simplify the determination of the thermodynamic parameters and XAFS spectra which base on the second-order cumulant only. In particular, this method can be applied for both theoretical calculations and experimental measurements in the XAFS method.

Research objectives of the thesis: Clarification influence of the elements Na, Sr and Ba substituting for La/Ca and crystal size on the magnetic properties, phase transition and magnetocaloric effects of La0,7Ca0,3MnO3 materials. Found the materials for significant mmagnetocaloric parameters have potential for applications in magnetic refrigeration.Determine the effect of replacing Sr/Ba for Ca in La0,7Ca0,3MnO3 and Co substituting for Mn in La0,7Sr0,3MnO3 on their critical behavior as well as the ferromagnetic interactions order.

In recent years, optical orthogonal frequency division multiplexing (OOFDM) has emerged as a dominant research and development area in the field of high-speed optical communications. OFDM is a potential candidate as the most promising next-generation optical networks such as passive optical networks and optical transport networks, due to their simple configuration based on low cost, high speed data rates, high spectral efficiency, high quality of service and robustness against narrow band interference, frequency selective fading, and chromatic dispersion.

The aim of the study was to investigate the crystallization kinetics and solidification behaviour of Fe60Co8Mo5Zr10W2B15 bulk glass forming alloy. The solidification behaviour in near-equilibrium and non-equilibrium cooling conditions was studied. The eutectic and peritectic reactions were found to exist in the solidification sequence of the alloy. The bulk metallic glass formation was achieved by using two methods: quenching from the liquid state and quenching from the semi-state.

Digital signal processing has revolutionized the storage and transmission of audio and video signals as well as still images, in consumer electronics and in more scientific settings (such as medical imaging). The main advantage of digital signal processing is its robustness: although all the operations have to be implemented with, of necessity, not quite ideal hardware, the a priori knowledge that all correct outcomes must lie in a very restricted set of well-separated numbers makes it possible to recover them by rounding off appropriately. ...
