Abstract:
This paper presents a critical historical review of the two main approaches to providing an understanding of the nature of the weak nuclear force via the Standard Model and the Generation Model of particle physics. The Standard Model is generally considered to be incomplete in the sense that it provides little understanding of several empirical observations: the Generation Model was developed to overcome several dubious assumptions made during the development of the Standard Model. This paper indicates that the Generation Model provides a more consistent understanding of the weak nuclear force than the earlier Standard Model.

Abstract:
We consider an anomaly free extension of the standard model gauge group G SM by an abelian group to G SM ⊗ U ( 1 ) Z . The condition of anomaly cancellation is known to fix the Z-charges of the particles, but two. We fix one remaining charge by allowing for all possible Yukawa interactions of the known left-handed neutrinos and new right-handed ones that obtain their masses through interaction with a new scalar field with spontaneously broken vacuum. We discuss some of the possible consequences of the model.

Abstract:
It has been shown that, in a bilateral force-matching task, subjects presenting weakness in one limb produce a lower force in the weakened limb even though they subjectively perceive that they are exerting the same force. The aim of this study was to verify whether subjects with hemiparesis produced asymmetrical forces during a bilateral submaximal grip task and whether this asymmetry is related to weakness of the paretic limb. Fifteen subjects with hemiparesis and 15 healthy subjects were recruited. First, the maximal voluntary force was measured for each hand. Then, subjects were asked to exert equal forces with both hands simultaneously at three submaximal force levels using two dynamometers. In the bilateral task, the force ratios (paretic/nonparetic or nondominant/dominant) differed between groups. Severely weak hemiparetic subjects produced lower force ratios than mildly weak hemiparetic subjects and healthy subjects ( P < 0.000), whereas there was no difference between the force ratios produced by mildly weak hemiparetic subjects and those produced by healthy subjects. In subjects with hemiparesis, the force ratios in the bilateral task were related to the ratios of maximal voluntary forces ( R2 = 0.39–0.66, P ≤ 0.013) and the presence of somatosensory impairment did not affect these relationships. These results suggest that the strategy used is to compare the intensity of the motor commands on both sides and then perform the force-matching task. The use of such a strategy by subjects who have had paresis for 1 year reflects a lack of adaptation to their weakness.

Full text
Abstract:
This thesis project investigates two of the mechanisms that have been postulated to explain the origin of the molecular homochirality found in living systems. These mechanisms are i. the Yamagata-Rein Hypothesis, which predicts that the weak neutral currents between electrons and nucleons result in a Parity-Violating Energy Difference (PVED) between a pair of molecular enantiomers; and ii. the Vester-Ulbricht Hypothesis, which predicts that the β-particles produced during weak force mediated nuclear β-decay interact differently with each of a pair of molecular enantiomers. Both hypotheses predict a small enantiomeric excess and theorise that such an excess might have been the prebiotic chiral influence that led to homochirality, which is generally accepted to be a prerequisite for biology. It is found that those PVED computations carried out the coupled-perturbed level of theory are approximately one order of magnitude larger than those previously computed at the entry-level uncoupled-perturbed level of theory. The results computed as part of this thesis project include the first to apply Density-Functional theory to the computation of the PVED. The coupled-perturbed Hartree-Fock and Kohn-Sham computations of the PVED are found to be in good agreement with recent related computational studies. The hypersensitivity of the PVED to small conformational changes, coupled to the difficulties in knowing the aqueous phase structure of even small chiral biomolecules such as α-alanine, means that it is difficult to make any unambiguous conclusions regarding which of a pair of biomolecular enantiomers might have been favoured by the PVED in a probiotic regime. These results do indicate that the largest β-asymmetries are generated in the forward scattering regimes and that the sign of the asymmetries may change suddenly as the energy of the incoming β-particle increases so as to allow the removal of electrons from successive molecular orbitals during the impact ionisation of the molecule.

Full text
Abstract:

Machining with diamond tools, whether turning or milling has proven itself as themanufacturing process that produces the highest quality surface finish, with the leastamount of form error in the minimum amount of time. However, due to tool wear and theamount of force generated during conventional machining, diamond tools cannot be usedon carbon containing materials such as steel and brittle materials such as silicates. In anattempt to by-pass the material limitations of diamond machining, a new machiningprocess called vibration assisted machining (VAM) has been developed. VAM involvesoscillating the diamond tool, bringing it into and out of contact with the material in rapidsuccession. VAM can either be 1-dimentional (1D), oscillation in a single direction, or 2-dimensional (2D), a summation of two independent tools motions. Currently, researchefforts are focused on 2D vibration machining, 2D tool motion haven been shown to besuperior to 1D tool motion. Over the past 10 years, 2D VAM with diamond tools hasbeen demonstrated to reduce the amount of machining force and increase tool life whenmachining carbon-containing materials over that of conventional machining processes.However the mechanisms of this improvement have yet to be discovered. This researcheffort is focus on: 1) discovering the fundamental mechanical principals behind theimprovement, force reduction and tool wear, 2) developing a model that predicts thecutting forces and tool contact times, 3) establishes guidelines for the use of vibrationassisted machining and 4) developing an industrial grade 2D VAM servo. The reductionsin tool wear and machining forces are related to the path geometry of the diamond tooland the speed and the depth at which it engages the workpiece. A model has beendeveloped and experimentally verified for 2D VAM which predicts the machining forcesand workpiece / tool contact time if the material properties are known. Along with themodel, a set of charts has been developed for both 1D and 2D VAM that relate the keymachining variables to one another. Lastly, a robust 2D VAM diamond tool servo hasbeen designed.

Samad-Suhaeb, Mujahid. "Aerodynamics of battle damaged finite aspect ratio wings." Thesis, Loughborough University, 2005. https://dspace.lboro.ac.uk/2134/10736.

Full text
Abstract:
When an aircraft is aerodynamically or structurally damaged in battle, it may not able to complete the mission and the damage may cause its loss. The subject of aircraft battle survivability is one of critical concern to many disciplines, whether military or civil. This thesis considered and focused on Computational Fluid Dynamics [CFD] predictions and experimental investigations into the effects of simulated battle damage on the low-speed aerodynamics of a fmite aspect ratio wing. Results showed that in two-dimensional [2d] and three-dimensional [3D] CFD simulations, Fluent's® models work reasonably well in predicting jets flow structures, pressure distributions, and pressure-coefficient Cp's contours but not for aerodynamic coefficients. The consequences were therefore that CFD prediction was poor on aerodynamic-coefficients increments. The prediction of Cp's achieved good agreement upstream and near the damage hole, but showed poor agreement at downstream of the hole. For the flow structure visualisation, at both weak and strong jet incidences, the solver always predicted pressure-distribution-coefficient lower at upstream and higher at downstream. The results showed relatively good agreement for the case of transitional and strong jet incidences but slightly poor for weak jet incidences. From the experimental results of Finite Wing, the increments for Aspect-ratio, AR6, AR8 and ARIO showed that as damage moves out towards the tip, aerodynamic-coefficients increments i.e. lift-loss and drag-rise decreased, and pitching-moment-coefficient increment indicated a more positive value at all incidence ranges and at all aspect ratios. Increasing the incidence resulted in greater magnitudes of lift-loss and drag-rise for all damage locations and aspect ratios. At the weak jet incidence 4° for AR8 and in all of the three damage locations, the main characteristics of the weak-jet were illustrated clearly. The increments were relatively small. Whilst at 8°, the flow structure was characterised as transitional to stronger-jet. In Finite Wing tests and for all damage locations, there was always a flow structure asymmetry. This was believed to be due to gravity, surface imperfection, and or genuine feature. An 'early strong jet' that indicated in Finite Wing-AR8 at 'transitional' incidence of 8°, also indicated in twodimensional results but at the weak-jet incidence of 4°. For the application of 2d data to AR6, AR8, and ARIO, an assessment of 2d force results led to the analysis that the tests in the AAE's Low Turbulence Tunnel for 2d were under-predicting the damage effects at low incidence, and over-predicting at high incidences. This suggested therefore that Irwin's 2d results could not be used immediately to predict three-dimensional.

Full text
Abstract:
The present work was conducted in Sandvik Coromant to enhance the knowledge and understanding of general flank wear growth and specifically in this case flank wear growth on the cutting edge of the coated (Ti(C, N)/ Al2O3/ TiN) tool inserts.   Reliable modeling of tool life is always a concern for machining processes. Numbers of wear models studies predicting the tool life length have been created throughout the metal-cutting history to better predict and thereby control the tool life span, which is a major portion of the total cost of machining.   A geometrical contact model defining the geometry of the flank wear growth on the cutting tool inserts was proposed and then compared with four suggested models, which estimates flank wear. The focus of this work is on the initial growth of flank wear process and thereby short cutting-time intervals are measured.   Wear tests on cutting tool inserts were performed after orthogonal turning of Ovako 825 B steel and were analysed by optical instrument, 3D optical imaging in Alicona InfiniteFocus and EDS in SEM. Force measurements for cutting speeds, Vc, 150, 200, and 250 m/min and feed rate, fn, 0.15 mm/rev were recorded as well.   Results show that initial flank wear land, VB, growth is dominated by sliding distance per cutting length for different cutting speeds. A good correlation between the geometrical contact model and estimation models is indentified. The cutting force measurements compared with the flank wear land show proportionality between two parameters. For the machining data in the present study the flank wear rate per sliding distance, dW/dL, is estimated to 2x103 (μ3/m).

Abstract:
The applications of micro-end-milling operations have increased recently. A Micro-End-Milling Operation Guide and Research Tool (MOGART) package has been developed for the study and monitoring of micro-end-milling operations. It includes an analytical cutting force model, neural network based data mapping and forecasting processes, and genetic algorithms based optimization routines. MOGART uses neural networks to estimate tool machinability and forecast tool wear from the experimental cutting force data, and genetic algorithms with the analytical model to monitor tool wear, breakage, run-out, cutting conditions from the cutting force profiles. The performance of MOGART has been tested on the experimental data of over 800 experimental cases and very good agreement has been observed between the theoretical and experimental results. The MOGART package has been applied to the micro-end-milling operation study of Engineering Prototype Center of Radio Technology Division of Motorola Inc.

Abstract:
AbstractCompetition law—also known as antitrust in some jurisdictions—has become part of governments’ policy arsenal to achieve efficient and welfare-improving market outcomes. From only a handful of economies in North America and Europe, the adoption of competition law and policy has spread rapidly to Asian economies since 1990. Like their Western counterparts several decades earlier, most Asian jurisdictions have exempted agriculture, albeit in varying degrees, from the prohibitions of competition law, such as those involving the exercise of market power by farmers’ associations. Public choice considerations suggest that the exemption serves as a countervailing force for the farmers’ comparatively weak position in the balance of political influence for agricultural policy and in bargaining power over the more concentrated wholesale-retail segments of the agri-food value chain. Farm heterogeneity and farm-operation consolidation, induced in part by the economy’s structural transformation, weaken the case for broad exemption.

Abstract:
The present work introduces a tunable parametric amplifier (PA) with a hardening, Duffing-type nonlinearity. By introducing a multi-frequency parametric excitation, one is able to achieve both: (i) High amplification of the weak, low-frequency external excitation (ii) Projection of the low frequency on any natural frequency of the system, thus transforming the low frequency excitation to a frequency band where signal levels are considerably higher. Having developed multiple-scales based expressions for the response of such systems, it is demonstrated that (a) The analytical analysis agrees well with numerically obtained simulations. (b) Both the phase, magnitude and spatial projection of this force on any system’s eigenvector can be retrieved by appropriate selection of parameters, with superior signal to noise levels. Closed form analytic expressions for the sensitivity and gain are derived and analyzed. Additionally, some practical applications envisaged for the proposed method will be outlined.

Abstract:
Review question / Objective: The aim of this systematic review is to synthesize the scientific evidence that evaluates fatigue and fracture resistance, survival, and stress distribution, of composite resin CAD/CAM and ceramic CAD/CAM occlusal veneers in posterior teeth with severe occlusal wear. Condition being studied: Currently there is an increase in cases of dental wear, due to several factors such as: excessive consumption of carbonated drinks, a diet high in acids, gastric diseases, anorexia, bulimia, dental grinding, use of highly abrasive toothpastes, or a combination of these(9) (10) (11) (12); which affect the patient in several aspects: loss of vertical dimension, sensitivity due to the exposure of dentin, esthetics, affectation of the neuromuscular system(11) (13) (14). With the advent of minimally invasive dentistry, occlusal veneers have been found to be a valid option to rehabilitate this type of cases and thus avoid greater wear of the dental structure with full coverage restorations. Sometimes when performing a tabletop it is not necessary to perform any preparation, thus preserving the maximum amount of dental tissue(3) (6) (15). Due to the masticatory load either in patients without parafunction where the maximum masticatory force is approximately 424 N for women and 630 N for men or in those who present parafunction where the maximum bite force can vary from 780 to 1120N(7), it is necessary that the occlusal veneers support that load which makes indispensable a compilation of studies investigating both fatigue and fracture resistance and the survival rate of occlusal veneers in different materials and thicknesses.

Abstract:
This study was undertaken by Oxfam in three South Sudanse counties as part of the SIDA-funded project 'Building Resilience through Gender and Conflict-Sensitive Approaches to Education, Skills Development, and Sustainable Livelihoods'. Its purpose was to shed light on why so many girls drop out of school. The research revealed that women and girls often lack decision-making power over their lives. Early or forced marriage, the abduction of girls, perceptions that education delays marriage – and that educated girls risk not finding husbands – all contribute to dropout rates. Additional challenges include a lack of adequate hygiene and sanitation facilities in schools, the distances learners need to travel, insecurity caused by communal violence, floods, food insecurity, and a heavy household work burden. The Government of South Sudan has in place laws and policies to address these issues, but they remain largely on paper and enforcement mechanisms are weak. The report analyses each of these factors in turn and presents recommendations for how the SIDA project can begin to address them in its future programming.

Full text
Abstract:
Telecommuting is defined as “a work practice that involves members of an organization substituting a portion of their typical work hours (ranging from a few hours per week to nearly full-time) to work away from a central workplace—typically principally from home —using technology to interact with others as needed to conduct work tasks”(Allen, Golden, & Shockley, 2015: 44). This kind of practice substantially differs from the regular and ordinary modes of work because employees perform their usual work in different settings, usually from home (Allen et al., 2015). Although research has been conducted on telecommuting since the 1970s, it has recently become critical when life incidents, like the COVID-19 pandemic has forced many to work from home. Such events offer rare opportunities, for a wide range of researchers and from various fields, to study important questions that would not typically be able to be asked, such as about telecommuting experiences. We took this opportunity and conducted two studies regarding telecommuting, basing our rationale on the fact that many on-site employees were forced to work from home, across a wide range of occupations as a direct result of the pandemic(Kramer & Kramer, 2020). The aim of our study, thus, was to investigate the preferences of employees who were forced to work from home. Specifically, bycreating latent profiles from important work and personality related constructs, we aimed at predicting employees’ preference for working from home or working on-site based on these profiles, and further investigate the relationship of these latent profiles to perceived productivity, job satisfaction, and job engagement.

Abstract:
The UK government’s Integrated Review of security, defence, development and foreign policy, published in March 2021 alongside a supporting defence command paper, set a new course for UK national security and highlighted opportunities for an innovative approach to international engagement activity. The Integrated Review focused principally on the state threats posed by China’s increasing power and by competitors – including Russia – armed with nuclear, conventional and hybrid capabilities. It also stressed the continuing risks to global security and resilience due to conflict and instability in weakened and failed states. These threats have the potential to increase poverty and inequality, violent extremism, climate degradation and the forced displacement of people, while presenting authoritarian competitors with opportunities to enhance their geopolitical influence. There are moral, security and economic motives to foster durable peace in conflict-prone and weakened regions through a peacebuilding approach that promotes good governance, addresses the root causes of conflict and prevents violence, while denying opportunities to state competitors. The recent withdrawal from Afghanistan serves to emphasize the complexities and potential pitfalls associated with intervention operations in complex, unstable regions. Success in the future will require the full, sustained and coordinated integration of national, allied and regional levers of power underpinned by a sophisticated understanding of the operating environment. The UK armed forces, with their considerable resources and global network, will contribute to this effort through ‘persistent engagement’. This is a new approach to overseas operations below the threshold of conflict, designed as a pre-emptive complement to warfighting. To achieve this, the UK Ministry of Defence (MOD) must develop a capability that can operate effectively in weak, unstable and complex regions prone to violent conflict and crises, not least in the regions on the eastern and southern flanks of the Euro-Atlantic area. The first step must be the development of a cohort of military personnel with enhanced, tailored levels of knowledge, skills and experience. Engagement roles must be filled by operators with specialist knowledge, skills and experience forged beyond the mainstream discipline of combat and warfighting. Only then will individuals develop a genuinely sophisticated understanding of complex, politically driven and sensitive operating environments and be able to infuse the design and delivery of international activities with practical wisdom and insight. Engagement personnel need to be equipped with: An inherent understanding of the human and political dimensions of conflict, the underlying drivers such as inequality and scarcity, and the exacerbating factors such as climate change and migration; - A grounding in social sciences and conflict modelling in order to understand complex human terrain; - Regional expertise enabled by language skills, cultural intelligence and human networks; - Familiarity with a diverse range of partners, allies and local actors and their approaches; - Expertise in building partner capacity and applying defence capabilities to deliver stability and peace; - A grasp of emerging artificial intelligence technology as a tool to understand human terrain; - Reach and insight developed through ‘knowledge networks’ of external experts in academia, think-tanks and NGOs. Successful change will be dependent on strong and overt advocacy by the MOD’s senior leadership and a revised set of personnel policies and procedures for this cohort’s selection, education, training, career management, incentivization, sustainability and support.

Abstract:
In 2020, the US Army Engineer Research and Development Center (ERDC), Coastal and Hydraulics Laboratory, provided technical oversight during a navigation study to assist the Galveston District evaluation of different channel widening alternatives for larger ships transiting the Houston Ship Channel (HSC), Texas. The widening proposals encompassed several areas of the HSC including the Bay Section, the Bayport Ship Channel, Barbours Cut Channel, and the Bayou Section. The study was performed at the San Jacinto College Maritime Technology and Training Center (SJCMTTC) Ship/Tug Simulator (STS) Facility in La Porte, TX. The SJCMTTC STS is a real-time simulator; therefore, events on the simulator happen at the same time rate as real life. A variety of environmental forces act upon the ship during the simulation transit. These include currents, wind, waves, bathymetry, and ship-to-ship interaction. Online simulations of the project were conducted at SJCMTTC over a 3-week period – May through June 2020. Several mariners including Houston Pilots and G&H tugboat Captains participated in the testing and validation exercises. ERDC oversight was performed remotely because of the COVID-19 pandemic. Results in the form of engineering observations, track plots, and pilot interviews were reviewed to develop final conclusions and recommendations regarding the final design.

HYSTERETIC PERFORMANCE OF WEAK-AXIS CONNECTION WITH I-SHAPED PLATES IN STEEL FRAME. The Hong Kong Institute of Steel Construction, September 2021. http://dx.doi.org/10.18057/ijasc.2021.17.3.1.

Full text
Abstract:
This paper elucidates numerically the behavior of weak-axis moment connections proposed by welding I-shaped plates in the H-section column to increase connection strength and ductility in steel frame. After validating the numerical methods through comparing the results of numerical analysis and experiments, the effectiveness of the proposed weak-axis connection were examined through comparing to the traditional weak-axis connection. The proposed weak-axis connection could move the highest stresses away from the start-stop points of a weld, and thus preventing the premature brittle fracture of the beam flange welds. The plastic hinge formed away from the beam-column interface, while the local buckling occurred in the weld access holes region in the traditional weak-axis connection. The proposed weak-axis connections can be classified as rigid in a strong-bracing system, and be classified as semi-rigid in weak-supported or unsupported system. And then a series of parametric studies was conducted to better understand the behavior of proposed weak-axis moment connections. The force-displacement relationships, location of the plastic hinge, Mises index (MI), triaxiality index (TI) and rupture index (RI) distributions at the beam flange welds were reported in detail. According to the numerical analysis, the design variables of I-shaped plates and widened flange plate are suggested, along with a design procedure.

EXPERIMENTAL STUDIES OF THE SORBITE STAINLESS STEEL PLUG-PIN SCAFFOLD JOINT. The Hong Kong Institute of Steel Construction, December 2022. http://dx.doi.org/10.18057/ijasc.2022.18.4.9.

Full text
Abstract:
Systematic experimental studies were performed for the purpose of obtaining the material properties of cold-formed sorbite stainless steel and the mechanical parameters of plug-pin joint. As a new type of material, the scaffold made of sorbite stainless steel has the advantages of convenient construction, high strength and stainless steel. The static tensile tests for S500 sorbite stainless steel investigating the material characteristics of plug-pin joint were carried out. The bending moment, the compressive force, the tensile force and the shear force were applied to the joint respectively. To get the failure modes and moment-rotation (or load-displacement) curves, the joint behavior, including the semi-rigidity between the ledger and the standard, compression and shear of the standard, and the tension of the ledger joint were studied. The result can determine the load-bearing capacity and the performance of the joint. The joint stiffness was determined according to different methods and four models were proposed to describe the bending behavior. By analyzing the different modes of joint failure, the weak part can be determined to provide basis for actual joint design.
