Beam Modulation System for the Qweak Experiment at Jefferson Lab

The Qweak experiment aims to measure the weak charge of the proton to 4% via the parity-violating asymmetry ($\sim$-200 ppb) in elastic e+p scattering. The scattering rate is largely influenced by five beam parameters: horizontal position (X), angle (X'), vertical position (Y), angle (Y'), and beam energy (E). Changes in these parameters when the beam polarization is reversed will create a false asymmetry. To measure the detector sensitivities, we modulate X, X', Y, Y' using four air-core dipoles in the Hall C beamline as well as beam energy with a superconducting RF cavity. Linear regression is then used to remove the false asymmetry. The beam modulation system has also proven valuable for tracking changes in the Hall-C beamline optics including dispersion at the target.Comment: 3 pages, 2 figures, CIPANP 201

Web development productivity improvement through object-oriented application framework

Most of the commercial and industrial web applications are complex, difficult to implement, risky to maintain and requires deep understanding of the requirements for customization. As today's software market is more competitive, productivity has become a major concern in software development industry. The aim of this research is to design and develop an application framework for accelerating web development productivity through object-oriented technology. It allows customization, design reuse and automatic code generation to support productivity improvement as a breakthrough solution for the given problem. This research employed systematic literature review (SLR) to identify the source of complexity and productivity factors. Agile development methodology was used to design the framework and it was validated by empirical data from two commercial projects. Results showed that object-oriented application framework (OOAF) has significant factors that affect productivity and dramatically improve higher productivity over traditional approach. It has fulfilled the current needs by reducing complexities, development efforts and accelerates web development productivity. This research contributes in the area of software engineering, specifically in the field of software productivity improvement and software customization. These will lead to faster development time for software industries

Observability and scientific realism

The goal of this thesis is to explore the debate between Bas van Fraassen’s constructive empiricism and scientific realism. For this purpose I discuss the existence of observable and unobservable entities, the observation/theoretical dichotomy, inference to the best explanation, the no miracles argument, pessimistic induction, and epistemic risk. I strive to show that, contrary to the view of constructive empiricism, there is no clear demarcation line between observable and unobservable entities, and that not only naked eye observation but also the instrument-based observation plays an important role in acquiring knowledge. I agree with scientific realists that there is no highest point to the human power of observation; it is open-ended for further development. Moreover, naked eye observations are not themselves beyond doubt, as sometimes even naked eye observations deceive us. In that context, theoretical explanations help us to understand the real situation. As such, there is no reason to give more credit to naked eye observations than to instrument-mediated, theory-informed observations. Scientific realists are confident in their knowledge of unobservables, and reject the epistemic significance of the observable/unobservable distinction. To justify their knowledge of unobservables, they use inferences to the best explanation. Such inferences play an important role in choosing the best theory amongst a group of theories. For their part, constructive empiricists use what is called the ‘bad lot’ argument to refute these inferences. I try to show that such ‘bad lot’ arguments fail to succeed at undermining inferences to the best explanation. Following scientific realists, I assert that nothing is miraculous in the domain of science, and that we can be assured of the approximate truth of successful scientific theories. It is true that many contemporary scientific theories contradict previously successful scientific theories, but that does not compel us to be pessimistic about such contemporary theories. Instead of pessimism, we can have an optimistic attitude about the progress of science. Considering the different arguments of constructive empiricism and scientific realism, this thesis gives more credit to scientific realism than to constructive empiricism

Comparative Study between Analytical Method and Finite Element Method of a Cylindrical Bore Journal Bearing Behaviour

This thesis describes a comparative study between analytical method and finite element method of a cylindrical bore journal bearing behaviour. In calculating the performance characteristics of a journal bearing such as pressure distribution, load capacity, flow requirement and power loss, isothermal analysis was carried out. Using both analytical method and finite element method, the effects of variations in operating variables such as eccentricity ratio and shaft speed on the bearing design parameters were calculated. With regard to CPU time, analytical method performs better than finite element method; but in terms of obtained results, finite element method shows better performance than analytical method. The analytical results and finite element results are compared. In order to check the validity, when these results are compared with the available published results, on the whole, finite element results show better agreement than analytical results
