An Analysis of the Sutpen Brothers in Absalom, Absalom!

William Faulkner is a famous American novelist, and he won the Nobel Prize for literature in 1949. He was regarded as “modern classic writer” by western Literature. Absalom, Absalom! is one of his most important works, and is also one of the most complicated and abstruse, the most epic style works. The book’s title comes from a Bible story, and the story describes the love and hate between parents and children, between brothers, and also describes the ambiguous relationship between the brother and sister. Through these descriptions, William Faulkner created vivid characters, and through these characters, William Faulkner revealed the rotten and evil nature of racism of the Old South

A BIOMECHANICAL ANALYSIS OF THE UPPER LIMB ON DIFFERENT SNOOKER BATTING TECHNIQUES

The purpose of this study was to compare the kinematics of the upper limb in fellow shot and draw shot, to quantify the effects of the different rods on technical characteristics. Eight professional snooker athletes hit the placed snooker balls using the fellow and draw shots, respectively. Ten kinematic variables were collected for each shot. Paired t-tests were used to analyze the effect of different rod method on the performance of upper limbs. The flexion-extension angle of the elbow (p=0.03) and the hand-rod angle (p=0.02) were larger when the fellow shot was used, while the hitting speed (p=0.01)and the hitting angle (p=0.01) was less than draw shot. Stroke in the draw shot required a large range of elbow and hand-rod angles during the T1-T2 and T2-T3 stages. No statistical differences were found in the kinematics of the wrist. The fellow shot is more stable than the draw shot, and the rod speed may be the main reason for the difference in kinematics between different rod methods

Multilevel optimisation of aerospace and lightweight structures incorporating postbuckling effects

The optimisation of aerospace structures is a very complex problem, due to the hundreds of design variables a multidisciplinary optimisation may contain, so that multilevel optimisation is required. This thesis presents the recent developments to the multilevel optimisation software VICONOPT MLO, which is a multilevel optimisation interface between the well established analysis and design software packages VICONOPT and MSC/NASTRAN. The software developed is called VICONOPT MLOP (Multilevel Optimisation with Postbuckling), and allows for postbuckling behaviour, using analysis based on the Wittrick-Williams algorithm. The objective of this research is to enable a more detailed insight into the multilevel optimisation and postbuckling behaviour of a complex structure. In VICONOPT MLOP optimisation problems, individual panels of the structural model are allowed to buckle before the design load is reached. These panels continue to carry load with differing levels of reduced stiffness. VICONOPT MLOP creates new MSC/NASTRAN data files based on this reduced stiffness data and iterates through analysis cycles to converge on an appropriate load re-distribution. Once load convergence has been obtained with an appropriate criterion, the converged load distribution is used as a starting point in the optimisation of the constituent panels, i.e. a new design cycle is started, in which the updated ply thicknesses for each panel are calculated by VICONOPT and returned to MSC/NASTRAN through VICONOPT MLOP. Further finite element analysis of the whole structure is then carried out to determine the new stress distributions in each panel. The whole process is repeated until a mass convergence criterion is met. A detailed overview of the functionality of VICONOPT MLOP is presented in the thesis. A case study is conducted into the multilevel optimisation of a composite aircraft wing, to demonstrate the capabilities of VICONOPT MLOP and identify areas for future studies. The results of the case study show substantial mass savings, proving the software's capabilities when dealing with such problems. The time taken for this multilevel optimisation also proves the efficiency of the software.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

Determining Validity of a Point of Interest Based on Existing Data

Generally, the present disclosure is directed to determining whether or not a point of interest is valid based on existing data. In particular, in some implementations, the systems and methods of the present disclosure can include or otherwise leverage one or more machine-learned models to predict a likelihood of a point of interest being valid based on ‘clues’ gathered from existing data

Quantum Interactions in Topological R166 Kagome Magnet

Kagome magnet has been found to be a fertile ground for the search of exotic quantum states in condensed matter. Arising from the unusual geometry, the quantum interactions in the kagome lattice give rise to various quantum states, including the Chern-gapped Dirac fermion, Weyl fermion, flat band and van Hove singularity. Here we review recent advances in the study of the R166 kagome magnet (RT6E6, R = rare earths; T = transition metals; and E = Sn, Ge, etc.) whose crystal structure highlights the transition-metal-based kagome lattice and rare-earth sublattice. Compared with other kagome magnets, the R166 family owns the particularly strong interplays between the d electrons on the kagome site and the localized f electrons on the rare-earth site. In the form of spin-orbital coupling, exchange interaction and many-body effect, the quantum interactions play an essential role in the Berry curvature field in both the reciprocal and real spaces of R166 family. We discuss the spectroscopic and transport visualization of the topological electrons hosted in the Mn kagome layer of RMn6Sn6 and the various topological effects due to the quantum interactions, including the Chern-gap opening, the exchange-biased effect, the topological Hall effect and the emergent inductance. We hope this work serves as a guide for future explorations of quantum magnets.Comment: Submitted versio
