Results are presented from a series of simulations undertaken to determine the effect of a novel form of molecular biaxiality upon the phase behaviour of the well established Gay-Berne (GB) liquid crystal model. Firstly, the simulation of a bulk system interacting via the Internally-Rotated Gay-Berne (IRGB) potential, which offers a single-site representation of a molecule rigidly constrained into a zig-zag conformation, is presented. The results of simulations performed for systems of IRGB particles with an aspect ratio of 3:1 confirm that the introduction of biaxiality into the model results

This generalizes results appearing in [38]. We then apply our result to classify the blocks of group algebras whose defect group is not quatemion and for which a maximal m-orthogonal module exists.

Abstract:
Optical diffraction tomography (ODT) is a tomographic technique that can be used to measure the threedimensional (3D) refractive index distribution within living cells without the requirement of any marker. In principle, ODT can be regarded as a generalization of optical projection tomography which is equivalent to computerized tomography (CT). Both optical tomographic techniques require projection-phase images of cells measured at multiple angles. However, the reconstruction of the 3D refractive index distribution post-measurement differs for the two techniques. It is known that ODT yields be

We report the possibility to control the tilting of nanoneedles and nanowires by using structured sapphire substrates. The advantage of the reported strategy is to obtain well oriented growth along a single direction tilted with respect to the surface normal, whereas the growth in other directions is suppressed. In our particular case, the nanostructures are tilted with respect to the surface normal by an angle of 58°. Moreover, we demonstrate that variation of the nanostructures shape from nanoneedles to cylindrical nanowires by using SiO2 layer is observed.

In a standing acoustic wave field, particles experience a force towards the acoustic nodes which is proportional to the particle volume. This force is opposed by the drag force on the particle from the fluid. The drag force is proportional t

碩士<br>義守大學<br>電機工程學系<br>104<br>The transmission, reflection and radiation spectrum of fiber Bragg gratings (FBGs) with a polarization controller are measured in this thesis, where FBGs include first-order FBGs, tilted FBGs (TFBGs) and second-order FBGs. The experimental results show that polarization controllers do not affect the properties of FBGs. However, the radiated efficiencies increase 5.55dB and 5.88dB by a polarization controller for 1° and 45° TFBGs, respectively. The maximum radiation efficiency of TFBGs can reach 6.25dB. In addition, we measured the radiation efficiency as a functi

碩士<br>高雄醫學院<br>牙醫學研究所<br>87<br>The purpose of this study was to evaluate the stress distributions to the abutments of a fixed partial denture with tilted molar abutments. In cases of the lower first molar being missing, photoelastic models were made with 3-unit fixed partial dentures of which the second molars were tilted 0 degrees, 10 degrees, 20 degrees, 30 degrees, and 40 degrees mesially towards the occlusal surface. A vertical load of 79.0 Newton was applied distally to the pontic 9mm from the marginal ridge of the second premolar. Quasi-3D photoelastic stress analysis was used, and the s

Chips need to possess sound and stable processing performance under various operating conditions. In order to eliminate high temperature effects and to assure longer life circle, heat dissipation in smart phones is an important topic. This study measures the temperature distribution in a horizontally oriented cell phone as the benchmark. Numerical simulation is conducted to obtain the thermal field under same condition. It is found that the agreement between the

碩士<br>國防大學中正理工學院<br>電子工程研究所<br>94<br>The purpose of this study is to implement a biochemical sensor based on a tilted fiber Bragg grating (TFBG). For the slanted gratings, the number of cladding modes and the intensity of the loss peaks of cladding modes are dependant on the tilted angle. This phenomenon can be confirmed by the theoretical calculations and experimental results. However the sensing sensitivity of the higher modes comparing with that of the core mode or lower order modes should be better for monitoring the biochemical media.

The tilt angles vary from 0 degree to 60 degrees with an increment of 10 degrees. As the angle increases, the temperatures of the front MCPCB’s and the LED lenses increase accordingly whereas the rear temperatures decrease at first and then increase. The experimental results depict similar trend to the numerical simulations. At the inclination angle of 10 degrees,
