Abstract:

2010/2011<br>The goal of this dissertation is to explain how the X-ray photoelectron diffraction technique can be successfully employed in the structural investigation of complex surface interfaces of ultra-thin films. Local geometrical analysis, combined with other techniques that gain additional electronic and surface morphological information to the system investigated, shed light on those extremely complicated surface atomic systems. These studies are aimed to contribute to the many interesting applications in fields like nano-electronics, surface coating and magnetic storage devices.<br>

Abstract:

A novel method by which to calculate the near edge X-rayabsorption fine structure region of the X-ray absorption spectrum has been derived and implemented. By means of damped coupled cluster theory at coupled cluster levels CCS, CC2, CCSD and CCSDR(3), the spectra of neon and methane have been investigated. Using methods incorprating double excitations, the important relaxation effects maybe taken into account by simultaneous excitation of the core electron and relaxation of other electrons. An asymmetric Lanczos-chain driven approach has been utilized as a means to partially resolve the excit

Abstract:

The work in this PhD thesis covers two strands of x-ray experiments: firstly, the characterisation of large arrays of dense structures by means of x-ray scattering, and, secondly, the investigation of hybrid anisotropy square structures with x-ray microscopy. The ability to accurately characterise large arrays of nanoscale magnetic structures is a key requirement for both scientific understanding and technological advance such as bit patterned recording media (BPM). In this work small angle x-ray scattering (SAXS) was investigated as a characterisation technique for large arrays of patterned s

Abstract:

Technical improvements of imaging devices during the last two decades have led to the development of so called hybrid imaging modalities, containing at least two different imaging modalities in the same machine. Hybrid imaging allows the combination of multi-modal images and the extraction of both complementary and synergistic information, which is useful for more accurate and reliable diagnosis. Within this framework there was an increased need for multi-modal contrast agents. During the last decade development of multi-modal contrast agents have hence received further attention. Rec

Abstract:

Gamma-ray binaries are extreme systems that produce non-thermal emission from radio to very-high-energy (above TeV) gamma rays, with the energy output in the spectral energy distribution (SED) dominated by the MeV–GeV photons. Their broadband emission is usually modulated by the orbital cycle of the system, which suggests that the physical conditions are also periodic and reproducible. The diversity of systems, together with the reproducibility of the conditions within each system, makes gamma-ray binaries excellent physical laboratories in which high energy particle acceleration, diffusion, a

MCDS is an autosomal dominant skeletal dysplasia disorder caused by mutations in collagen X. In most cases, mutations in collagen X result in a misfolded protein which is retained within the ER of hypertrophic chondrocytes, causing increased ER stress. It has previously been demonstrated that increased ER stress causes hypertrophic chondrocytes to de-differentiate in an attempt to avoid the stress. The altered differentiation results in reduced cell hypertrophy and impaired vascular invasion accounting for reduced bone growth. The presence of increased ER stress in hypertrophic chondrocytes is

However, the variation increasing in the process can also possibly occur. Therefore, this study makes the discussion in view of this part and the Duncan’s model was extended. Through the Visual Basic software to carry on a computerized system development and design that optimizes the quality control chart. Apart from considering the mean shift, the variance increases influences on sample size, interval between samples and width of control limits

Abstract:

Application of smart curing concept called internal curing (IC) is the most promising strategy for mitigating autogenous shrinkage and related early-age cracking in cement-based materials with low water-to-cement ratio. There are still many theoretical and practical questions that need to be answered before IC could become a standard method. Many of these questions concern the most appealing of water-regulating additives for IC called Superabsorbent Polymers (SAP). The clear linkage between SAP material properties, the moment of water release and the effect on autogenous shrinkage is still mis

Abstract:

碩士<br>國立中央大學<br>物理研究所<br>91<br>Finite size X-ray diffraction theory was used to determine the mean particle diameter and size distribution of powders composed of nano-scale particles. The X-ray diffraction patterns were analyzed assuming a single size as well as multi sizes for the powder. Better fits were frequently obtained when a size distribution for the powder was assumed, as expected. Gaussian and Lognormal distributions were then considered. Through the process, we were able to determine the size distribution of the powder by using the x-ray diffraction pattern. Comparisons of the

Abstract:

The PhD thesis work has been focused on aprotic Li-O2 cells assembled with different cathode materials in combination with the ether-based LiTFSI/TEGDME electrolyte. The performance of these promising energy storage systems have been investigated and related to the electrochemical and chemical processes at the triple O2/cathode/electrolyte interface and to the peculiar influence of each type of cathode material. These goals have been achieved by a powerful combination of techniques such as X-ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SE

Abstract:

碩士<br>逢甲大學<br>電聲碩士學位學程<br>104<br>This study used the Leaky Filter-x Normalized Least Mean Square (Leaky Filter-x NLMS) algorithm to develop a feed-forward active noise control (ANC) system for the active control of noise in kitchen hoods. It is hoped that the resulting ANC system can effectively reduce the noise in kitchen hoods. With regard to hardware, a microphone amplifier was used to record and amplify the sound signal. In order to improve the ANC system, a low-pass filtered is developed. Additionally, this study presents a method how to choose a better placement point for noise reduct

Abstract:

No<br>The effect of a self-induced electric field is investigated analytically and numerically on differential and mean electron spectra produced by beam electrons during their precipitation into a flaring atmosphere as well as on the emitted hard X-ray (HXR) photon spectra. The induced electric field is found to be a constant in upper atmospheric layers and to fall sharply in the deeper atmosphere from some "turning point" occurring either in the corona (for intense and softer beams) or in the chromosphere (for weaker and harder beams). The stronger and softer the beam, the higher the electri

Abstract:

A presente tese tem como objectivo estabelecer um procedimento de análise de amostras heterogéneas com o M4 TORNADO, através do estudo da variabilidade e distribuição espacial dos elementos químicos constituintes de um grupo de amostras de solo e sedimentos, recolhidas na área da antiga mina de São Domingos, localizada no concelho de Mértola (Portugal), em plena Faixa Piritosa Ibérica (FPI). Após a peneiração das amostras em quatro classes (≥ 2 mm, < 2 mm e ≥ 500 μm, < 500 μm e ≥ 250 μm e < 250 μm) no laboratório, as amostras foram analisadas sob a forma de pastilhas no M4 TORNADO
