description: This thesis is about investigation of untapered and tapered fibre transmission properties by experimentation and simulation. Tapered fibre fabricated from commercial products and custom fibre from Bath University was investigated including different fibre type, taper length, and taper ratios. Simulations of untapered and tapered fibre by consideration of geometrical optics using Zemax are presented and compared to electromagnetic waveguide simulations using COMSOL. In addition, the impact of modal noise in tapered fibre is investigated, especially graded-index tapers, by quantifying macro- and micro-bending loss. Moreover, the fabrication of build-inhouse connector tapered fibre is introduced as a robust and cost-saving tool for spectrograph link. Lastly, a tapered fibre is tested with a compact EXOplanet high-resolution SPECtrograph (EXOhSPEC) of the University of Hertfordshire using Tungsten and ThAr lamps. Although the cladding light is detected clearly in custom graded-index taper, the light throughput in EXOhSPEC is improved. Overall these results indicate the potential for reasonable fibre-fed spectrograph performance using a ’single tapered fibre’.

description: Radio-loud active galactic nuclei (RLAGN) produce jets on large scales heating their local environments and preventing the hot phase of baryonic matter from cooling hence slowing or halting galaxy formation and evolution; a model popularly known as AGN feedback. To understand this model, new views of low-luminosity compact RLAGN inhabiting massive galaxies have been obtained using the new LOw Frequency ARray (LOFAR) northern-sky radio survey LoTSS (LOFAR Two Metre Sky Survey) to study RLAGN in the local Universe at low frequencies (150 MHz). In this thesis, I investigate lowluminosity compact RLAGN selected from LoTSS first Data Release (DR1) in an attempt to reveal their radio morphologies and the physical scales at which they affect the inter-galactic medium (IGM) of the host galaxy on sub-kpc scales. We have conservatively selected 55 low-luminosity compact RLAGN based on LoTSS DR1 within redshift range 0:03 < z < 0:1. I show using high-frequency Jansky Very Large Array (VLA) observations that only 9 out of 55 objects show extended radio emission (1-3 kpc), 43 are compact at the limiting angular resolution of 0.35 arcsec (corresponding to projected maximum physical sizes of < 1 kpc), while 3 are undetected. The extended objects display a wide range of radio morphologies on smaller angular scales: doubles (3), two-sided jets (3), one-sided jets (2), and complex (1). I discuss their radio spectra which range from steep to flat and/or inverted radio spectra (-1:31 < α < 0:36) and span the range seen in various compact RLAGN such as compact symmetric objects (CSOs), compact steep spectrum (CSS) sources, and gigahertz peaked-spectrum (GPS) sources. Assuming synchrotron self-absorption (SSA) models for flat and/or inverted radio spectrum sources, I predict the physical sizes of 35 RLAGN to be between 2-53 pc. On their position on the power-linear size (P - D) diagram, we see that these objects populate the bottom left lower-end of the diagram; this position corresponds to the low-radio power CSOs. Finally, I compare their radio properties with those of the Fanaroff-Riley class 0 (‘FR0’) sources. Interestingly, some of the compact RLAGN presented in this thesis show extended radio emission in the second Data Release (DR2) images; these appear to be in fact the radio cores of low-luminosity yet extended Fanaroff-Riley (FRI/FRII) sources that could populate the right-lower end of the P - D diagram, limited by LOFAR’s surface brightness. Could we be underestimating the sizes of some of these compact objects? Continued VLBI observations of LOFAR sources could help us answer this question, which in turn will help us further understand AGN feedback. i
Hopes Matter: Adolescents’ Coping and Identity Searching for Maternal Absence in Rural China

Year: 2022
Subjects: subject: Identity Searching

description: The present MA thesis study focuses on rural Chinese adolescents being raised by single fathers without a mother regularly present in the home. Using in-depth qualitative data collected from 8 rural teenagers in Mangshui, Yunnan, Southwestern China, the study examines how adolescents in rural China experience maternal absence and cope with that experience. It also inquires about how maternal absence impacts a specific developmental task, the identity searching, of these young people. The author argues that rural adolescents experience a considerable amount of stress because of emotional disconnection with biological mothers; the social stigma generated by the mother-absent family structures; paternal high expectations for them to improve family situations and shake off the social stigma; and a lack of safe space within the households to address experienced stress. At the same time, rural adolescents receive general emotional support from significant others. They also gain emotional support from the life philosophy introduced by social media and the school curriculum to specifically address issues of maternal absence. Based on the life philosophy, rural adolescents perceive themselves as powerless to change their current situation and focus on what is possible in the future. They imagine desirable images of themselves in a future state and use these images as effective coping strategies to redirect attention, modulate emotion, preserve hopes, and take action. Suffering from maternal absence, young people are clear about what they like to be and dislike to be in the future. These explicit renderings of assumed roles in adulthood, as a result, help them navigate not only life challenges but also identity crisis in adolescence.

description: A pulsar timing array is a Galactic-scale detector of nanohertz gravitational waves (GWs). Its target signals contain two components: the `Earth term' and the `pulsar term' corresponding to GWs incident on the Earth and pulsar respectively. In this work we present a Frequentist method for the detection and localization of continuous waves that takes into account the pulsar term and is significantly faster than existing methods. We investigate the role of pulsar terms by comparing a full-signal search with an Earth-term-only search for non-evolving black hole binaries. By applying the method to synthetic data sets, we find that (i) a full-signal search can slightly improve the detection probability (by about five percent); (ii) sky localization is biased if only Earth terms are searched for and the inclusion of pulsar terms is critical to remove such a bias; (iii) in the case of strong detections (with signal-to-noise ratio $\gtrsim$ 30), it may be possible to improve pulsar distance estimation through GW measurements.

Creators: name: Woretaw, Alebel
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2012

description: To survive and grow organizations must be constantly kept up to date through effective training and development programs. Employee training and development is especially important in industries with rapidly changing technology such as shoe industries. Having this in mind, the study has been conducted in Ethiopia shoe factories (ASSC and TASSC) to assess employee training and development practices. The methodologies used to undertake the study were both primary and secondary data collection. Besides to this, the number of participants for this study was 336 employees. The finding of the study revealed that the shoe factories weakness in training and development practice such as with respect to periodic and clear need assessment, selection criteria, training and development methods, training period's adequacy and training evaluation. However, training and development was as such good in relation to trainer's capabilities, stating in training and development objectives. Thus, the factories should keep up with their strengths and should alleviate their weaknesses by applying clear and scientific principles regarding human resource training and development.

description: Security of online transactions is a key factor that affects a potential buyer's decision to make purchases online. In Thailand, security has been identified as the main reason for consumers' reluctance in purchasing products online. E-commerce rates in Thailand are considerably lower than those of other countries in the same region. However, this could be interpreted as a potential for e-commerce growth in Thailand. This study aims to identify the main factors affecting the low rates of e-commerce activity in Thailand and explores the social and cultural aspects of online shoppers here. Through a survey of Thais who shop online, this research aims to understand consumers' behaviours and their opinions relevant to security of online transactions. The research employs a qualitative approach and a questionnaire survey to collect pertinent data. Results show a strong association between confidence in online security and the number of potential online buyers. E-commerce in Thailand can grow fully when appropriate security strategies have been developed. This can make potential buyers more confident about making online purchases. This finding has been confirmed using knowledge from across disciplines. Mathematical equations (adding test value, recalculating and mathematically reconstructing the data structure) and the laws of physics have been used to help explain this social behaviour as a conceptual idea of Mode-2 society. Following an in depth, trans-disciplinary analysis of the research data, some recommendations for the online industry and government entities have also been presented. The findings of the study and its recommendations focus on online trading activity can help in reducing fear or reluctance associated with online transactions among Internet users in Thailand and possibly leads to an increase in revenues from online shopping for the country.

description: We apply the Noether procedure for gauging space-time symmetries to theories with Galilean symmetries, analyzing both massless and massive (Bargmann) realizations. It is shown that at the linearized level the Noether procedure gives rise to (linearized) torsional Newton-Cartan geometry. In the case of Bargmann theories the Newton-Cartan form $M_μ$ couples to the conserved mass current. We show that even in the case of theories with massless Galilean symmetries it is necessary to introduce the form $M_μ$ and that it couples to a topological current. Further, we show that the Noether procedure naturally gives rise to a distinguished affine (Christoffel type) connection that is linear in $M_μ$ and torsionful. As an application of these techniques we study the coupling of Galilean electrodynamics to TNC geometry at the linearized level.

description: The accurate visual tracking of a moving object is a human fundamental skill that allows to reduce the relative slip and instability of the object's image on the retina, thus granting a stable, high-quality vision. In order to optimize tracking performance across time, a quick estimate of the object's global motion properties needs to be fed to the oculomotor system and dynamically updated. Concurrently, performance can be greatly improved in terms of latency and accuracy by taking into account predictive cues, especially under variable conditions of visibility and in presence of ambiguous retinal information. Here, we review several recent studies focusing on the integration of retinal and extra-retinal information for the control of human smooth pursuit.By dynamically probing the tracking performance with well established paradigms in the visual perception and oculomotor literature we provide the basis to test theoretical hypotheses within the framework of dynamic probabilistic inference. We will in particular present the applications of these results in light of state-of-the-art computer vision algorithms.

Year: 2016

description: This study analyzes the impact of foreign assistance on saving and economic growth in Sub- Saharan African countries for the period 1991 to 2014. The empirical analysis has been performed by using Panel Data Estimation method. The main result shows that the effect of foreign assistance on economic growth was positive and significant in the short run. While in the long run, the effect was found to be positive and significant albeit diminishing return to foreign assistance. From the same estimation it was also found that, import has strong effect on economic growth of the nations under study. The other variable considered in this estimation was the macroeconomic stability situation of the sub Saharan African countries and this variable has strong and direct effect on economic growth through enhancing effectiveness of aid. The other focus of the study was effect of foreign aid on the domestic savings. According to the regression result there is significant negative relationship between the level of saving and foreign assistance at 10% level of significance.

description: Absolute photoionisation cross sections for the Cl$^+$ ion in its ground and the metastable states; $3s^2 3p^4\; ^3P_{2,1,0}$, and $3s^2 3p^4\; ^1D_2,\; ^1S_0$, were measured recently at the Advanced Light Source ALS) at Lawrence Berkeley National Laboratory using the merged beams photon-ion technique at an photon energy resolution of 15 meV in the energy range 19 -- 28 eV. These measurements are compared with large-scale Dirac Coulomb {\it R}-matrix calculations in the same energy range. Photoionisation of this sulphur-like chlorine ion is characterized by multiple Rydberg series of autoionizing resonances superimposed on a direct photoionisation continuum. A wealth of resonance features observed in the experimental spectra are spectroscopically assigned and their resonance parameters tabulated and compared with the recent measurements. Metastable fractions in the parent ion beam are determined from the present study. Theoretical resonance energies and quantum defects of the prominent Rydberg series $3s^2 3p^3 nd$, identified in the spectra as $3p\rightarrow nd$ transitions are compared with the available measurements made on this element. Weaker Rydberg series $3s^2 3p^3 ns$, identified as $3p \rightarrow ns$ transitions and window resonances $3s3p^4 (^4P)np$ features, due to $3s \rightarrow np$ transitions are also found in the spectra.

Using an array of technical tools, from geometric analysis for the free boundaries, we reduce the problem to its scalar counterpart and hence conclude similar results as that of scalar problem. This can also be seen as the most novel part of the paper, that possibly can lead to further developments of free boundary regularity for systems.

description: Guided movement in response to slowly diffusing polymeric trails provides a unique mechanism for self-organization of some microorganisms. To elucidate how this signaling route leads to microcolony formation, we experimentally probe the trajectory and orientation of Pseudomonas aeruginosa that propel themselves on a surface using type IV pili motility appendages, which preferentially attach to deposited exopolysaccharides. We construct a stochastic model by analyzing single-bacterium trajectories, and show that the resulting theoretical prediction for the many-body behavior of the bacteria is in quantitative agreement with our experimental characterization of how cells explore the surface via a power law strategy.

description: At the core of the world’s most pressing security challenges lie a multitude of protracted interstate rivalries and conflicts. . Amongst the literature that deals with the de-escalation of protracted conflicts, Karen Rasler’s model stands out as an evolutionary framework. framework. The framework has held substantial explanatory power in understanding how protracted dyadic conflicts de-escalate and the necessary conditions that have allowed for de-escalation to occur in the 10 most prominent cases of dyadic conflicts in the modern age. However, it is evident that in many ways, the world has changed substantially in recent times and possibly, so has the fundamental nature of conflicts. The question that must be asked then is, does the 20-year-old theory still hold relevance? Can a theory that has worked well in explaining conflicts of the past, be robust enough to stand up to the changing contextual situations of today? It is this question I am attempting to explore through this paper by way of a plausibility probe. In order to probe the theory in today’s day and age, I use one of the most the pertinent cases of a protracted dyadic conflict post World War II – the case study of India and Pakistan.

description: Electron transport is studied in surface oxidized single-crystal copper thin films with a thickness of up to 5.6 nm by applying density functional theory and density functional tight binding methods to determine electron transport properties within the ballistic regime. The variation of the electron transmission as a function of film thickness as well as the different contributions to the overall electron transmission as a function of depth into the the films is examined. Transmission at the oxidized copper film surfaces is found to be universally low. Films with thickness greater than 2.7 nm exhibit a similar behavior in local transmission per unit area with depth from the film surface; transmission per unit area initially increases rapidly and then plateaus at a depth of approximately 0.35-0.5 nm away from the surface, dependent on surface facet. Unstrained films tend to exhibit a higher transmission per unit area than corresponding films under tensile strain.

Failure mode reasoning in safety-critical programs
Creators: name: Jahanian, Hamid
Publisher: name: Macquarie University
Year: 2023
Subjects: Other education not elsewhere classified

description: In the process industry, a Safety Instrumented System (SIS) is a mechanism that protects against process-related hazards. The failure of an SIS can result in catastrophic failure of the plant and potentially loss of lives. It is therefore crucial that the failure modes of SISs are known and addressed early in the design and realization stage. An SIS comprises hardware components and a software element – the program. The main role of the program is to process real-time readings from the sensors, which monitor the status of the plant, and decide if a safety action should be triggered to save the plant from a hazardous event. Failure Mode Reasoning (FMR) is a new method for analyzing the transformation of faults through SIS programs. Where the subject of study is the program itself, FMR helps identify potentially incorrect parameters within the program. Where the program is considered “as intended,” the method helps identify the combinations of SIS input failure modes that can result in undesired outputs. FMR uses the program architecture for deductive reasoning. The process begins with a given output failure as the premise and concludes with a list of potential causes of the failure being produced. FMR employs an abstraction technique to derive the program’s failure behavior from its functional behavior. The method is compositional and can be applied to any program architecture, regardless of its complexity. Herein, we describe the concepts, formalize the method and demonstrate its application in industrial case studies. We also generalize the method for its use in failure modeling in generic systems, as opposed to its specific application in SIS programs.

description: We study a universe filled with dust-like matter in the form of discrete inhomogeneities (e.g., galaxies and their groups and clusters) and two sets of perfect fluids with linear and nonlinear equations of state, respectively. The background spacetime geometry is defined by the FLRW metric. In the weak gravitational field limit, we develop the first-order scalar and vector cosmological perturbation theory. Our approach works at all cosmological scales (i.e. sub-horizon and super-horizon ones) and incorporates linear and nonlinear effects with respect to energy density fluctuations. We demonstrate that the scalar perturbation (i.e. the gravitational potential) as well as the vector perturbation can be split into individual contributions from each matter source. Each of these contributions satisfies its own equation. The velocity-independent parts of the individual gravitational potentials are characterized by a finite time-dependent Yukawa interaction range being the same for each individual contribution. We also obtain the exact form of the gravitational potential and vector perturbation related to the discrete matter sources. The self-consistency of our approach is thoroughly checked. The derived equations can form the theoretical basis for numerical simulations for a wide class of cosmological models.

description: Polymorphic variants are a useful feature of the OCaml language whose current definition and implementation rely on kinding constraints to simulate a subtyping relation via unification. This yields an awkward formalization and results in a type system whose behaviour is in some cases unintuitive and/or unduly restrictive. In this work, we present an alternative formalization of poly-morphic variants, based on set-theoretic types and subtyping, that yields a cleaner and more streamlined system. Our formalization is more expressive than the current one (it types more programs while preserving type safety), it can internalize some meta-theoretic properties, and it removes some pathological cases of the current implementation resulting in a more intuitive and, thus, predictable type system. More generally, this work shows how to add full-fledged union types to functional languages of the ML family that usually rely on the Hindley-Milner type system. As an aside, our system also improves the theory of semantic subtyping, notably by proving completeness for the type reconstruction algorithm.

Year: 2007

description: Empirical analysis on economic effects of liberalization in the context of African air transport sector is not much discussed in the literature and the continent's policy makers and the industry operators need such analysis to implement liberalization initiatives. As such, the purpose of this study is to empirically measure economic effects of progressive air transport liberalization in Africa by taking the case of 20 city-pair routes to/from Addis Ababa for the period 2000-2005. By employing a Two-Stage Least Square estimation procedure for a panel data set, passenger demand, fare and departure frequency models are estimated to see the impact of Bilateral Air Service Agreement (BASA) liberalization. Liberal policies are assumed to affect the two supply side variables, i.e. fare and departure frequency. Accordingly, the frequency model indicates that a significant increase in departure frequency is observed in routes that experienced both 'full' and 'restricted' type of liberalization compared to those governed by restrictive bilateral arrangements. In addition, higher increase in the number of departure frequency in routes which experienced restricted liberalization relative to those operated under fully liberalized arrangement is observed. Regarding the fare model, a statistically significant negative impact of liberalization policy on standard economy fare is not found. Finally, it is recommended that liberalizing BASAs, especially provisions pertaining to departure frequency, will enhance service quality.

description: Bogoliubov transformations have been successfully applied in several Condensed Matter contexts, e.g., in the theory of superconductors, superfluids, and antiferromagnets. These applications are based on bulk models where translation symmetry can be assumed, so that few degrees of freedom in Fourier space can be `diagonalized' separately, and in this way it is easy to find the approximate ground state and its excitations. As translation symmetry cannot be invoked when it comes about nanoscopic systems, the corresponding multidimensional Bogoliubov transformations are more complicated. For bosonic systems it is much simpler to proceed using phase-space variables, i.e., coordinates and momenta. Interactions can be accounted for by the self-consistent harmonic approximation, which is naturally developed using phase-space Weyl symbols. The spin-flop transition in a short antiferromagnetic chain is illustrated as an example. This approach, rarely used in the past, is expected to be generally useful to estimate quantum effects, e.g., on phase diagrams of ordered vs disordered phases.

description: Malaysia has the highest obesity prevalence in the Southeast Asian region, with half of the adult population having excess body weight. Guided by pragmatism, this PhD explores patients’ and health practitioners’ perspectives on obesity and obesity management in Peninsular Malaysia. The studies found discrepancies between patients' needs and practitioners' perspectives on obesity management in Malaysia. Patients appreciate practitioner-initiated weight discussions, and need more effective and motivational communication from healthcare practitioners. In contrast, practitioners feel that patients lack the motivation to lose weight. Obesity management in Malaysia warrants consideration of a shift from the current weight-centred approach to a health-centred approach.

description: The Lamb shift (self-energy) of an elliptic dielectric microcavity is studied. We show that the size of the Lamb shift, which is a small energy shift due to the system-environment coupling in the quantum regime, is dependent on the geometry of the boundary conditions. It shows a global transition depending on the eccentricity of the ellipsis. These transitions can be classified into three types of decay channels known as whispering-gallery modes, stable-bouncing-ball modes, and unstable-bouncing-ball modes. These modes are manifested through the Poincaré surface of section with the Husimi distribution function in classical phase space. It is found that the similarity (measured in Bhattacharyya distance) between the Husimi distributions below critical lines of two different modes increases as the difference of their self-energies decreases when the quality factors of the modes are on the same order of magnitude.

description: This work is devoted to the study of the existence of solutions to nonlocal equations involving the fractional Laplacian. These equations have a variational structure and we find a nontrivial solution for them using the Mountain Pass Theorem. To make the nonlinear methods work, some careful analysis of the fractional spaces involved is necessary. In addition, we require rather general assumptions on the local operator. As far as we know, this result is new and represent a fractional version of a classical theorem obtained working with Laplacian equations.

description: Procurement is a means by which an organization acquires works, good, consultancy and other services in a scientific manner. More than two third of the organization annual budget is spend through procurement. Every activity of the organization, either service or goods provider, is highly attached with the procured product. The purpose of this research is to assess the challenges and prospects of public procurement in outsourcing the non- core activities with a case study in Addis Ababa University. The study areas were four colleges namely Main Campus, Colleges of Business and Economics, Addis Ababa Institute of Technology (AAiT) and College of Natural Sciences on security and cleaning or janitorial services. The research is a descriptive study applying both quantitative and qualitative approach in which questioner was collected across a population through purposive sampling and uses descriptive statistics for the data analysis. The finding of the study shows that outsourced service assist Addis Ababa University to focus more on core functions and strategic areas, to save management time and upscale its primary objective of establishment as teaching and learning, conducting problem solving research and providing community service. On the other side, conflict of interest between outsourced employees and permanent University employees, difficulty to measure service/Product quality, Poor structure to manage the outsourced function , loss of autonomy in decision making, Possibility of harm and/ damage to university resource, high budget and cash flow requirement, leaking of information to competitors and loss of confidentiality and poor and/ infant Industries on the sector were the major challenges of the University due to outsourcing. Finally based on the finding, the researcher recommended that the University should conduct due diligence on the service provider's related work experience, quality of services provided, ethical considerations, technical capabilities, the resource possessed, the recruitment and selection criteria, and the reward packages provided. When it is used in a calculated and well-designed way, outsourcing could bring lots of benefits to the client organization. If applied without proper assessment of the capacities of service providers, it may involve irreparable damages in the short-range and could draw lots of risks that may disturb time-honored organizational culture. Hence, any form of outsourcing is likely called for maximizing benefits and minimizing risks.

description: The promotion of cash crop commercialisation and its effects on smallholder welfare have been debated for decades. This study uses cross-sectional data to examine the impact of cash cropping on food crop production at farm household level in Sheikan province in North Kordofan State, in Sudan. In addition to descriptive analysis, the study specifies and estimated models of groundnut commercialisation index and food crop production. The survey shows that the degree of agricultural commercialisation varied significantly a cross the entire sample, but still the semi-subsistent production features the production pattern in the area of study. Also, The empirical results show that groundnut commercialisation significantly and positively affected food crop production at household level. Commercialisation was significantly and negatively affected households' investment in livestock, but positively by family size. The study concludes that agricultural commercialisation has a positive and significant impact on household food crop production. Even when the households allocate more resources to cash crops, the earned income and access to food markets appears to justify their resource allocation
