description: The patterns and rates of sediment transport across coral reefs influence numerous ecological and morphological processes, yet these dynamics still remain poorly understood. We investigated rates of sediment transport across a 1:15 scale laboratory model with a 1:5 forereef slope, a fixed reef flat and a movable bed (sand) lagoon and beach. Four seven-hour irregular wave simulations were conducted with and without roughness elements on the forereef and reef flat, and with low and high mean water levels. Hydrodynamic processes were analyzed from 18 surface elevation and 8 velocity measurement stations. Suspended sediment concentration across the reef flat was measured continuously at five locations with fast response optical sensors that were periodically supplemented with direct pump sampling. Within the reef system, low frequency wave motions (both infragravity and very low frequency motions) were comparable and sometimes greater than short period motions that defined the incident wave band. Analysis of the sediment concentration signals and decomposition of velocity moments indicate that lower frequency motions play an increasing role across the reef flat and lagoon in driving sediment suspension and transport.
Spin-independent v-representability of Wigner crystal oscillations in one-dimensional Hubbard chains: The role of spin-charge separation

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: Electrons in one-dimension display the unusual property of separating their spin and charge into two independent entities: The first, which derive from uncharged spin-1/2 electrons, can travel at different velocities when compared with the second, built from charged spinless electrons. Predicted theoretically in the early sixties, the spin-charge separation has attracted renewed attention since the first evidences of experimental observation, with usual mentions as a possible explanation for high-temperature superconductivity. In one-dimensional (1D) model systems, the spin-charge separation leads the frequencies of Friedel oscillations to suffer a 2k_F -- 4k_F crossover, mainly when dealing with strong correlations, where they are referred to as Wigner crystal oscillations. In non-magnetized systems, the current density functionals which are applied to the 1D Hubbard model are not seen to reproduce this crossover, referring to a more fundamental question: Are the Wigner crystal oscillations in 1D systems non-interacting v-representable? Or, is there a spin-independent Kohn-Sham potential which is able to yield spin-charge separation? Finding an appropriate answer to both questions is our main task here. By means of exact and DMRG solutions, as well as, a new approach of exchange-correlation potential, we show the answer to be positive. Specifically, the v-representable 4k_F oscillations emerge from attractive interactions mediated by positively charged spinless holes -- the holons -- as an additional contribution to the repulsive on-site Hubbard interaction.
Time-Stampless Adaptive Nonuniform Sampling for Stochastic Signals

description: In this paper, we introduce a time-stampless adaptive nonuniform sampling (TANS) framework, in which time increments between samples are determined by a function of the $m$ most recent increments and sample values. Since only past samples are used in computing time increments, it is not necessary to save sampling times (time stamps) for use in the reconstruction process. We focus on two TANS schemes for discrete-time stochastic signals: a greedy method, and a method based on dynamic programming. We analyze the performances of these schemes by computing (or bounding) their trade-offs between sampling rate and expected reconstruction distortion for autoregressive and Markovian signals. Simulation results support the analysis of the sampling schemes. We show that, by opportunistically adapting to local signal characteristics, TANS may lead to improved power efficiency in some applications.

description: The Head Impact Video Evaluation (HIVE) is a tool for reviewing video footage to identify the circumstance of head impacts in ice hockey. An individual rater will analyze various characteristics of the impact, probed through the HIVE. For each question, instructions are included that provide definitions, interpretations, and guidelines to assist the rater in completing the question. In completing the HIVE, the rater should view the video footage on a high-quality computer screen (or LCD projector). The analysis should be completed in a quiet, private room. In analyzing the impact, the rater may view the video footage as many times as desired at any speed desired. Details on the development and inter-rater reliability of the HIVE can be found in Appendix B of the following dissertation: Aguiar, O. (2022).

description: Es lässt sich ein Wandel im Dienstleistungssektor beobachten (Leimeister, 2012), unter anderem verschärft sich die Wettbewerbssituation aufgrund gesättigter Märkten (Esch, 2019). Auch das Kaminfegerwesen steht vor neuen Herausforderungen, nicht zuletzt, weil sich das Berufsbild durch Entwicklungen in der Wärmeerzeugung verändert (Rutz & Schmid, 2014; Bundesamt für Energie, 2023; Kaminfeger Schweiz, 2020). In diesem Kontext gewinnt der Aufbau von starken Marken und die Markenführung an Bedeutung, um den zukünftigen Erfolg von Unternehmen zu sichern (Esch, 2019; Ghorbani & Westermann, 2023; Grossklaus, 2015). Ziel der Arbeit ist es, eine psychologische Positionierungsanalyse des Kaminfegerwesens durchzuführen und Differenzen zwischen Markenidentität und Markenimage in Bezug auf die Ist- und Soll-Positionierung aufzudecken. Die Untersuchung wurde mit Kaminfegermeister*innen als Expert*innen und Kundschaft aus den Hauptkundensegmenten der Kaminfegerbetrieben durchgeführt. Die Ergebnisse zeigen insbesondere eine grosse Diskrepanz im Verkauf. Es wird empfohlen, individuelle Positionierungsanalysen durchzuführen und eine leichte, auf die Marktsituation und die Bedürfnisse der Kundschaft abgestimmte Umpositionierung anzustreben. Das starke Image der Kaminfegerinnen und der persönliche Kontakte mit der Kundschaft spielen dabei eine entscheidende Rolle.

description: We investigate the non-adiabatic implementation of an adiabatic quantum teleportation protocol, finding that perfect fidelity can be achieved through resonance. We clarify the physical mechanisms of teleportation, for three qubits, by mapping their dynamics onto two parallel and mutually-coherent adiabatic passage channels. By transforming into the adiabatic frame, we explain the resonance by analogy with the magnetic resonance of a spin-1/2 particle. Our results establish a fast and robust method for transferring quantum states, and suggest an alternative route toward high precision quantum gates.

description: In the context of this thesis, a vulnerability assessment of factory metal construction will be carried out taking into account the interaction of soil - foundation - superstructure. In order to investigate the above case, a factory construction was studied which was simulated in the SAP2000 program as well as the tolerance of the soil characteristics was taken into account through the calculation of springs - impedance indices. Subsequently, an idiosyncratic analysis was carried out for both the compacted simulation and the simulation with springs - impedance indices in order to investigate the case of an increase in the eigenperiod of the system due to the influence of soil conditions. In addition, 30 dynamic time-history analyzes were performed from real seismic recordings from which the ratio of the maximum relative displacement of stories and story height was calculated. Also, results of floor node movements obtained after the analyzes were presented. While, interesting and expected movement results emerged comparing the two cases, this agreed system and the endowment system

description: The theory for the electric and magnetic fields energy absorption by small metallic particles subjected to the irradiation by ultrashort laser pulses of different duration in the region of surface plasmon excitation is developed. For the particles of the oblate or prolate spheroidal shape there has been found the dependence of the absorbed energy on a number of factors, including a particle radius, a degree of the shape deviation from a spherical one, a pulse duration, the orientation of the magnetic field upon particle, the magnitude of carrier frequency, and the value of a shift of the carrier frequency of a laser ray from the frequency of the surface plasmon excitation in a spherical particle. An appreciable absorption grows at the length of free electron pass large compared to the particle size is established. The phenomenological and kinetic approach is compared each with other.

description: Plants have been used as direct medicinal sources since ancient times as well as today. However, researchers and pharmacists are facing difficulties to identify medicinal plant parts before starting ingredient extraction in the laboratory. This study was conducted to identify the medicinal plant part based on multi-label categories by employing a sigmoid classifier as the last layer of Convolutional Neural Network (CNN). The study employed supervised learning approach in which the true values were predefined initially for the classifier using data annotation phase. Hence, leaf images of the plants were taken as an identity for the rest of the plant parts. The system was designed based on transfer learning by adopting (fine tune) the pre-trained models that employ CNN and trained using Image Net. High-resolution cameras for data acquisition and google Colab for the experiment (training and testing) were used. Mobile Net performed best with an accuracy of 93% for training sets and 92% for testing sets. When the models were evaluated using F1_score, it performed 94%. Without batch normalization at fully connected layer, this model scored 84%. So, Mobile Net obtained higher performance, and suitable to classify the medicinal plant body part. It was also taken as the fastest model to train because Mobile Net used depth wise separable convolution method that reduces scalar multiplication through convolution. By observing the results obtained from the presence and absence of batch normalization, this study deduced that batch normalization is advantageous to obtain good classification performances of the models.

Nursing workforce planning and radiation therapy treatment decision making : two healthcare operations research applications
Creators: name: Lavieri, Mariel Sofia
Publisher: name: University of British Columbia
Year: 2010

description: This thesis discusses two applications of operations research to healthcare: nursing workforce planning and radiation therapy treatment decision-making. The first application describes a linear programming-based hierarchical planning tool that determines the optimal number of nurses to train, promote to managerial levels and recruit over a 20 year planning horizon to achieve nursing and managerial targets. The model is based on the age dynamics and attrition rates of the nursing workforce. The tool has been developed to assist policy makers in planning the British Columbia registered nurses workforce. Its simplicity of use makes it ideal for scenario and “What-If” analyses. The second application presents a novel approach to model individual disease progression of prostate cancer patients who receive neoadjuvant hormone therapy before radiation therapy. The model is used to help clinicians determine when to initiate radiation therapy based on a patient’s prostate specific antigen (PSA) dynamics. Each patient’s PSA dynamics is modeled by a log quadratic curve. Prior distributions for the curve parameters are obtained from population characteristics. The distribution of the time of the PSA nadir is derived from an approximation of the ratio of two correlated normal random variables. Using a dynamic Kalman filter model, parameter estimates are updated as new patient-specific information becomes available. Clustering is incorporated to improve prior estimates of curve parameters. The model trades off the risk of beginning radiation therapy too soon, before hormone therapy has achieved its maximum effect, against waiting too long to start therapy after there has been a potential increase in the number of tumor cells resistant to the treatment. We illustrate and validate our modeling approach by comparing clinically implementable policies on a cohort of prostate cancer patients, and show that our approach outperforms the current protocol by identifying earlier when radiation therapy should start for each patient. While both applications involve very different approaches, they incorporate dynamic decision-making in the field of healthcare. A deeper knowledge of the potential of the field is achieved by understanding the challenges faced and methodology used to guide decisions on a policy level as well as on a patient-specific level.
Quantum de Sitter geometry

description: Quantum de Sitter geometry is discussed using elementary field operator algebras in Krein space quantization from an observer-independent point of view, {\it i.e.} ambient space formalism. In quantum geometry, the conformal sector of the metric becomes a dynamical degree of freedom, which can be written in terms of a massless minimally coupled scalar field. The elementary fields necessary for the construction of quantum geometry are introduced and classified. A complete Krein-Fock space structure for elementary fields is presented using field operator algebras. We conclude that since quantum de Sitter geometry can be constructed by elementary field operators, the geometry quantum state is immersed in the Krein-Fock space and evolves in it. The total number of accessible quantum states in the universe is chosen as a parameter of quantum state evolution, which has a relationship with the universe's entropy. Inspired by the Wheeler-DeWitt constraint equation in cosmology, the evolution equation of the geometry quantum state is formulated in terms of the Lagrangian density of interaction fields in ambient space formalism.

Scaling Law of Relativistic Sweet-Parker Type Magnetic Reconnection

description: Relativistic Sweet-Parker type magnetic reconnection is investigated by relativistic resistive magnetohydrodynamic (RRMHD) simulations. As an initial setting, we assume anti-parallel magnetic fields and a spatially uniform resistivity. A perturbation imposed on the magnetic fields triggers magnetic reconnection around a current sheet, and the plasma inflows into the reconnection region. The inflows are then heated due to ohmic dissipation in the diffusion region, and finally become relativistically hot outflows. The outflows are not accelerated to ultra-relativistic speeds (i.e., Lorentz factor ~ 1), even when the magnetic energy dominates the thermal and rest mass energies in the inflow region. Most of the magnetic energy in the inflow region is converted into the thermal energy of the outflow during the reconnection process. The energy conversion from magnetic to thermal energy in the diffusion region results in an increase in the plasma inertia. This prevents the outflows from being accelerated to ultra-relativistic speeds. We find that the reconnection rate R obeys the scaling relation R S^{-0.5}, where S is the Lundquist number. This feature is the same as that of non-relativistic reconnection. Our results are consistent with the theoretical predictions of Lyubarsky (2005) for Sweet-Parker type magnetic reconnection.

description: We study the classical dynamics of SU(2)-Higgs field theory using multiple scale perturbation theory. In the spontaneously broken phase, assuming small perturbations of the Higgs field around its vacuum expectation value, we derive a nonlinear Schroedinger equation and study the stability of its nonlinear plane wave solutions. The latter, turn out to be stable only if the Higgs amplitude is an order of magnitude smaller than that of the gauge field. In this case, the Higgs field mass possesses some bounds which may be relevant to the search for the Higgs particle at ongoing experiments.

description: This study explores the commercialization process of small to medium enterprises (SME’s), using the case study method to delve into the unique experiences of one firm who are currently in the process of commercialising their innovative low emission engine solutions. The study reviews the existing literature, exploring the challenges associated with commercialization, focusing on the specific challenges of commercialising high technologies into the market, and how the firm can aim to address the market’s needs and preferences. The gaps in the literature include a lack of knowledge on how SME’s can use their network during the commercialization process. The principal theories used to underpin this study include Teece’s Technological Commercialization Theory (Teece, Pisano , & Shuen, 1997), and the Network Theory (Ford & Mouzas, 2010). The SME is then situated within the context of industry, and the markets of interest are outlined, specifically the small power generation markets in Sub-Saharan Africa, India, and the United Kingdom. The study uses semi-structured interviews to gain qualitative data on the experiences of those in industry and within the SME. Through thematic analysis, the data was coded, and themes emerged. The analysis revealed a strong market need from the industry for low emission solutions to reduce carbon emissions, and a willingness to adopt high technologies, whilst also outlining the potential roadblocks of new innovations entering the market. The analysis from the participants within the SME indicate strong expertise in technological capabilities to meet the market need, whilst the challenges facing the SME surrounded financial resources and strategic direction. The study concludes by addressing the gaps in the literature through discussion of how the SME can navigate its associated challenges and access the market through its network.
Development and application of non-rejectable skin substitute to improve wound healing
Creators: name: Forouzandeh, Farshad
Publisher: name: University of British Columbia
Year: 2011

description: Skin substitutes consist of dermal and epidermal components are very beneficial to improve the current strategies of wound healing. However, these substitutes are not yet a routine treatment for burns or non-healing wounds mainly due to the difficulty of timely obtaining autologous skin cells. The aim of this study is to investigate the immunoprotective role of IDO in bilayer skin substitutes made out of non-autologous cells. To address this aim, first we asked the question of whether tryptophan deficient environment caused by IDO expression is safe for the survival of nonimmune cells, mainly primary skin cells. The results of our study showed a significant activation of apoptotic pathway as well as GCN2 kinase pathway in T cells, but not in skin cells, in response to the tryptophan deficient environment mediated by IDO expression. We then studied whether there is any differences between the main T cell populations in response to IDO mediated low tryptophan environment. Our results showed a marked immunosuppressive effect of IDO expression on human T cells with more suppressive effect on proliferation of CD8⁺ compared to that of CD4⁺ T cells which is, at least in part, due to differences in the level of GCN2 kinase pathway activation between these two sets of immune cells. Thereafter, we developed a bilayer skin substitute equipped with IDO expression ability. We found that IDO expressed by treated fibroblasts of this skin substitute suppress the proliferation of bystander lymphocytes in vitro considerably. Further, in our in vivo experiments, we found that the expression of IDO by cells of skin substitute significantly improved the wound healing rate, reduce the number of infiltrating T cells, and induced more revascularization in the wounds received IDO expressing skin substitutes compared to the non-IDO expressing ones. In conclusion, the results of this thesis research revealed that IDO expression can improve the efficacy of non-autologous bilayer skin substitutes to be used not oniy as a wound coverage, but also as a source of wound healing process improvement. A better revascularization seen in IDO grafted skin substitute further improved the graft take and survival.

description: Technology influences the way human beings connect with the outside world in their day-to-day businesses. Adopting new technologies can offer opportunities. It, also, poses threats. In the last many years it has been attempted to understand the very sophisticated relationship between society and technology. There is a belief that technology develops independently and that development in technology follows a somewhat linear order. Putting an emphasis on socio-cultural factors that have a role in technological development, some theorists become reluctant to claim that technology mainly determines society. The author of this paper is motivated to look at the issue of technology from philosophical perspective. Thus, this paper is intended to critically discuss the philosophical theory of technological determinism against social determinism, the two conflicting schools of thought in philosophy, and then open a room for further investigation/debate by researchers. Qualitative research method has been used. It used critical discussion as a tool. Literatures in the topic have been used so as to make a relatively comprehensive discussion. The finding of the literatures reviewed shows that the debate between the two schools has no end. The paper contributes to showing the unsettled debate between the two schools and summarizes by recommending further investigation.

description: With the recently discovered formula, which relates the off shell Euclidean one loop determinant to the on shell quantities such as normal and quasinormal modes in real spacetime, we work out the one loop partition function for $\mathcal{N}=1$ supergravity in AdS$_3$ from scratch. In passing, we also provide the explicit expression for one loop determinant of a field with arbitrary spin in AdS$_3$. To achieve this, we firstly derive the determinant expression for the one loop partition function in question using the powerful decomposition technique, and then we construct the normal modes in a purely algebraic way by demonstrating that the space of normal modes falls into the representation of SL(2,$R$) Lie algebra associated to AdS$_3$. The whole procedure developed here turns out to be much simpler than the previous strategy.

description: Ethiopian government has paid great attention to higher education expansion and hence, it has been a national policy issue of the country. The study investigated the dynamic relationship between higher education and economic growth in Ethiopia using annual data collected from 1981-2014. Autoregressive Distributive Lag framework was used along with Error Correction Term so as to investigate long run relationship between real GDP, enrollment in higher education, gross capital formation and labor. The result from bounds test confirmed the existence of strong long run relationship between variables. Enrollment in higher education and gross capital formation has a positive long-run effect on real GDP. But, only enrollment in higher education has a negative effect in the short run. The study utilized granger causality test in order to examine causal relationship between higher education and economic growth. According to the test result, a unidirectional causality running from higher education to economic growth was observed. The necessary diagnostic tests were applied in order to check reliability and acceptability of model outputs and they were found satisfactory. Drawing on the finding it is recommended that government should continue expanding the provision of higher education and in the meantime, endeavor to improve the quality of the provision.

description: The issue of urban mass transportation is becoming the center of cities' sustainable development and revitalization strategies. Hence, conducting a scientific inquiry into customers' satisfaction and service quality in urban light rail transport is vital to make policies and intervention measures instrumental and valid. The purpose of the study was to assess service quality and customer satisfaction in urban transport service delivery with particular reference to Addis Ababa City Light Rail Transit. To this end, the service performance (SERVPERF) model has been adapted and utilized as measurement constructs and a quantitative approach has been employed. The study was a descriptive and explanatory type involving the analysis of data collected through questionnaires from passengers of the Light Rail Transit. To analyze background information of respondents and their perception of service quality, descriptive statistics were applied. Besides, the study has utilized correlation and regression analysis. The finding of the study shows that the customers are moderately satisfied with assurance and responsiveness while they are dissatisfied with affordability, tangibility, reliability, and empathy. The correlation analysis of service quality dimensions (tangibility, reliability, responsiveness, assurance, empathy, and affordability) has shown, they all are positively correlated to overall service quality. Besides, all service quality dimensions have a significant effect on customer satisfaction implying that the higher the quality of service, the higher is the level of customers' satisfaction. In light of this, it is recommended that Addis Ababa light rail transit can improve customers’ satisfaction by working on quality.

A SPH model for incompressible turbulence

description: A coarse-grained particle model for incompressible Navier-Stokes (NS) equation is proposed based on spatial filtering by utilizing smoothed particle hydrodynamics (SPH) approximations. This model is similar to our previous developed SPH discretization of NS equation ({\it Hu X.Y. & N.A. Adams, J. Comput. Physics}, 227: 264-278, 2007 and 228: 2082-2091, 2009) and the Lagrangian averaged NS (LANS-$α$) turbulence model. Other than using smoothing approaches, this model obtains particle transport velocity by imposing constant $σ$ which is associated with the particle density, and is called SPH-$σ$ model. Numerical tests on two-dimensional decay and forced turbulences with high Reynolds number suggest that the model is able to reproduce both the inverse energy cascade and direct enstrophy cascade of the kinetic energy spectrum, the time scaling of enstrophy decay and the non-Guassian probability density function (PDF) of particle acceleration.

description: Anthracnose disease caused by Colletotrichum sublineolum is a major constraint that limits the production and productivity of sorghum in Ethiopia. A field experiment was carried out in Arba Minch and Derashe during the 2018/19 cropping season to determine the integrated effects of genotypes and reduced rates of fungicide applications on anthracnose disease, growth and grain yield of sorghum. The treatments were composed of four sorghum genotypes and three different rates of Ridomil Gold MZ 63.5% WP (Ridomil), including unsprayed and laid out in randomized complete block design with the factorial arrangement in three replications. Significant (p < 0.001) difference was observed in the magnitude of disease and crop parameters measured among the treatments considered. The disease severities were 22.78, 29.44, 62.22, and 66.11% on Arghiti, Melkam, Seredo and Local cultivar, respectively, because of a combination of Ridomil at the rate of 3 kg ha-1. These treatment combinations exceedingly reduced area under the disease progress curve and rates of disease progression as well. No statistically significant difference was observed on the grain yield obtained from plots sprayed with Ridomil at the rates of 2 and 3 kg ha-1 at 14 days intervals. A yield loss of 54.41% was recorded on unsprayed plots of the Local cultivar as compared to well-managed plots of other genotypes. The use of Arghiti and Melkam in combination with Ridomil at the rate of 2 kg ha-1 was found to be relatively efficient in reducing anthracnose development and gave higher grain yield as compared to the unsprayed plot. Therefore, the use of Arghiti and Melkam in combination with application of Ridomil at the rate of 2 kg ha-1 for the management of anthracnose could be suggested to sustain the production and productivity of sorghum for the farmers in the study areas and in similar agro-ecology. Further studies should be conducted in similar and other agro-ecologies in Ethiopia for at least one more year with over location to reach a concrete recommendation.
