description: NGC 6791 is a well-studied, metal-rich open cluster that is so close to us that can be imaged down to luminosities fainter than that of the termination of its white dwarf cooling sequence, thus allowing for an in-depth study of its white dwarf population. We use a Monte Carlo simulator that employs up-to-date evolutionary cooling sequences for white dwarfs with hydrogen-rich and hydrogen-deficient atmospheres, with carbon-oxygen and helium cores. The cooling sequences for carbon-oxygen cores account for the delays introduced by both Ne^22 sedimentation in the liquid phase and by carbon-oxygen phase separation upon crystallization. We do not find evidence for a substantial fraction of helium-core white dwarfs, and hence our results support the suggestion that the origin of the bright peak of the white dwarf luminosity function can only be attributed to a population of unresolved binary white dwarfs. Moreover, our results indicate that the number distribution of secondary masses of the population of unresolved binaries has to increase with increasing mass ratio between the secondary and primary components of the progenitor system. We also find that the observed cooling sequence appears to be able to constrain the presence of progenitor sub-populations with different chemical compositions and the fraction of non-DA white dwarfs. Our simulations place interesting constraints on important characteristics of the stellar populations of NGC 6791. In particular, we find that the fraction of single helium-core white dwarfs must be smaller than 5%, that a sub-population of stars with zero metallicity must be <12%, while if the adopted metallicity of the sub-population is solar the upper limit is ~8%. Finally, we also find that the fraction of non-DA white dwarfs in this particular cluster is surprinsingly small <6%.

Subjects: subject: Femtobasisstationen , Home Evolved NodeB
classificationCode: 620
subject: Ingenieurwissenschaften

description: Femtobasisstationen, die auch als Home Evolved NodeB bekannt sind, sind kleine Basisstationen mit niedriger Sendeleistung, welche innerhalb des traditionellen Makronetzwerkes eingesetzt werden. Mit diesen Kleinzellen wird die räumliche Wiederverwendung der Übertragungsressourcen enorm gesteigert, Wanddurchdringungsverluste stark abgeschwächt und höhere Datenraten erreicht. Allerdings erzeugen Femtobasisstationen auch Herausforderungen und die größte Herausforderung ist dabei die gesteigerte Interferenz. Die Abschwächung von Interferenz in Femtobasisstationsnetzwerken ist das Ziel dieser Arbeit. Um dieses Ziel zu erreichen, wurden die Charakteristiken und die Interferenzumgebung von Femtozellen erforscht und die Eigenschaften von für solche Netze geeigneten Interferenzschwächungstechniken studiert. Daher wurden dynamische Methoden zur zentralen und zur verteilten Ressourcenverteilung entwickelt, durch welche sich das Netzwerk selbstständig aktualisieren kann, abhängig von der Interferenzsituation. Zusätzlich wurden die vorgeschlagenen Techniken in aktuellen Standards wie Long-Term Evolution (LTE) und Long-Term Evolution-Advanced (LTE-A) getestet. Obwohl der Fokus hier auf Femtonetzwerken liegt, können die entwickelten Methoden mit kleinen Anpassungen auch in anderen Drahtlosnetzwerken eingesetzt werden.
description: Femto-BSs, also known as home evolved NodeB (HeNB), are low-power and small scale BSs that are deployed within traditional macro-cellular networks. With these so-called small cells, the spatial reuse of radio resources is tremendously boosted, wall penetration losses are largely mitigated, and users can enjoy high data rates. In addition to its various advantages, the deployment of femtocells also comes with some problems and one of the main issues is the increase in interference. The interference mitigation in femtocell networks is the main aim of this thesis. In order to achieve this goal, the characteristics and interference environment of femtocell deployments have been investigated, and the properties of interference mitigation techniques applicable to such networks are studied. To this end, dynamic central and distributed resource assignment methods have been developed where network can update itself depending on the changes in the interference environment. Furthermore, the application of the developed techniques in real network deployments such as Long-Term Evolution (LTE) and Long-Term Evolution-Advanced (LTE-A) have been studied. Although the focus is on femtocell networks, the developed methods in this thesis can be applied to any wireless networks with minor changes.

Machine learning-based multi-robot cooperative transportation of objects
Creators: name: Siriwardana, Pallege Gamini Dilupa
Publisher: name: University of British Columbia
Year: 2009

description: Multi robot cooperative transportation is an important research area in the multi robot domain. In the process of object transportation, several autonomous robots navigate cooperatively in either a static or a dynamic environment to transport an object to a goal location and orientation. The environment may consist of both fixed and removable obstacles and it will be subject to uncertainty and unforeseen changes within the environment. Furthermore, more than one robot may be required in a cooperative mode for handling heavy and large objects. These are some of the challenges addressed in the present thesis. This thesis develops a machine learning approach and investigates relevant research issues for object transportation utilizing cooperative and autonomous multiple mobile robots. It makes significant original contributions in distributed multi robot coordination and self deterministic learning for robot decision making, and comes up with an optimal solution to the action selection conflicts of the robots in the cooperative system. This will help to improve the real time performance and robustness of the system. Also, the thesis develops a new method for object and obstacle identification in complex environments using a laser range finder, which is more realistic than the available methods. A new algorithm for object pose estimation algorithm is developed, enabling a robot to identify the objects and obstacles in a multi-robot environment by utilizing the laser range finder and color blob tracking. The thesis develops a fully distributed hierarchical multi-robot architecture for enhanced coordination among robots in a dynamic and unknown environment. It strives to improve the real time performance and robustness. The system consists with three layers. By combining two popular artificial intelligence (Al) techniques such as learning and behavior based decision making, the developed architecture is expected to facilitate effective autonomous operation of cooperative multi-robot systems in a dynamically changing, unstructured, and unknown environment.

description: We study the variant of the k-local hamiltonian problem which is a natural generalization of k-CSPs, in which the hamiltonian terms all commute. More specifically, we consider a hamiltonian H over n qubits, where H is a sum of k-local terms acting non-trivially on O(log n) qubits, and all the k-local terms commute, and show the following -

1. We show that a specific case of O(log n) local commuting hamiltonians over the hypercube is in NP using the Bravyi-Vyalyi Structure theorem.

2. We give a simple proof of a generalized area law for commuting hamiltonians (which seems to be a folklore result) in all dimensions, and deduce the case for O(log n) local commuting hamiltonians.

3. We show that traversing the ground space of O(log n) local commuting hamiltonians is QCMA complete.

The first two behaviours seem to indicate that deciding whether the ground space energy of O(log n)-local commuting hamiltonians is low or high might be in NP or possibly QCMA, though the last behaviour seems to indicate that it may indeed be the case that O(log n)-local commuting hamiltonians are QMA complete.

description: The note presents a further study of the class of Cuntz--Krieger type algebras. A necessary and sufficient condition is identified that ensures that the algebra is purely infinite, the ideal structure is studied, % and applied to semigraph algebras, and nuclearity is proved by presenting the algebra as a crossed product of an AF-algebra by an abelian group. The results are applied to examples of Cuntz--Krieger type algebras, such as higher rank semigraph $C^*$-algebras and higher rank Exel-Laca algebras.
Quantum discord and noncontextual hidden variables models

description: It is shown that theoretically viable noncontextual hidden variables models in $d=2$ lead to conflicting dispersion free expressions in the analysis of the conditional measurement of two non-orthogonal projectors. No satisfactory criterion of the quantum discord, which relies on the analysis of conditional measurement, is formulated in the $d=2$ hidden variables space due to a lack of uniqueness of the dispersion free representation. We also make a speculative comment on a "many-worlds interpretation" of hidden variables models to account for the conditional measurement.

Transcripción paleográfica y critíca del mas 11017 de Trinity College, Dublin : La Regla de San Benito
Creators: name: Pajuelo, Carlos Antonio
Publisher: name: University of British Columbia
Year: 2009

description: The manuscript Trinity College, Dublin, MS 11017 (la Regla de San Benito—the Rule of St. Benedict) is one of the rare and unpublished medieval Hispanic codices to be found outside of Spain. At the moment it does not appear in any reference books or codex manuals. This codex was dedicated to the abbess of the monastery of Trasobares, in Aragon, Spain, and was translated from Late Latin to medieval Aragonese Spanish. According to Trinity College Library, Dublin, it dates to the year ca. 1450. During the Middle Ages, the existence of the Rule was crucial in the foundation of numerous Benedictine monasteries, which played a fundamental role in the expansion of Christianity across Europe. These monasteries also helped in the preservation and continuity of knowledge that came from Ancient Greece and Rome. The paleographic transcription of the codex MS. 11017 will be the main goal of this thesis. The study is divided in four chapters: the introduction, the research methodology, the study of the codex, and the paleographic transcription. The introduction includes: a historical context of Benedictine monasticism, a brief biography of Benedict of Nursia, a summary of the history and development of the Rule until the XIII century and a brief study of Spanish medieval monasticism until the writing of MS. 11017. The second part of this thesis will deal with the methodological approach for studying and transcribing the codex. The third chapter will thoroughly examine the different characteristics, the structure of the manuscript and the methods used for its edition. Finally, the last chapter will be the paleographic transcription of MS. 11017. This thesis will incorporate preliminary studies conducted by researchers and scholars of Benedict of Nursia and his rule, as well as contemporary versions of the Rule in Latin, Spanish, English and French. The study and transcription of MS. 11017 will be of great interest to individuals who wish to understand and expand their medieval monastic knowledge through the interdisciplinary study of its history, content and textual analysis, as well as the formation of pre-modern vernacular languages.

description: We investigate the effects of phase noise and particle loss on the dynamics of a Bose-Einstein condensate in an optical lattice. Starting from the many-body master equation, we discuss the applicability of generalized mean-field approximations in the presence of dissipation as well as methods to simulate quantum effects beyond mean-field by including higher-order correlation functions. It is shown that localized particle dissipation leads to surprising dynamics, as it can suppress decay and restore the coherence of a Bose-Einstein condensate. These effects can be applied to engineer coherent structures such as stable discrete breathers and dark solitons.

description: Honey is a natural product, consumed without the addition of any ingredient. Based on botanical origin, honey can be classified into monofloral and polyfloral honey. The objective of this study was to investigate the quality and special characteristics of Schefflera abyssinica and polyfloral honey collected from Sheka forest, Ethiopia. Botanical origin was determined based on Melissopalynology. Refractive index, moisture, sugars, ash, pH, free acidity, optical density, protein and color were determined by AOAC and hydroxymethylfurfural, diastase activity and electrical conductivity were determined by standard method of the international honey commission (IHC). Antioxidant activity and phytochemical content were determined using UV- visible spectroscopy. The level of pollen dominancy for Schefflera abyssinica was ranged from 76.2 to 85.8%. The polyfloral honey stuffed with variety of pollen grain ranged from 2.2% (Coffea arabica) to 23.2% (Schefflera abyssinica). It was found that Schefflera abyssinica honey had higher moisture (19.96 ± 0.26 g/100g), hydroxymethylfurfural (6.12 ± 2.14 mg/Kg), total phenol (75.08 ± 2.40 mg GAE/100g), total flavonoid (42.03 ± 1.49 mg QE/100 g) and also stronger DPPH (44.43 ± 0.97%) and hydrogen peroxide (78.00 ± 4.82%) scavenging activity than polyfloral honey

In dieser Dissertation wird ein Kontext spezifisches Modell zur Technologieakzeptanz basierend auf UTAUT2 entwickelt und um Nutzer, Service und Technologie relevante Aspekte erweitert. Das abgeleitete Modell wird mit Hilfe eines Strukturgleichungsmodells (PLS) auf Basis einer auf Szenarien basierenden empirischen Studie validiert. Die Ergebnisse der Analyse bestätigen das entwickelte Modell.
description: The tendency of brick and mortar retailers to adopt digital technologies to assist the information search and evaluation of customers in brick and mortar retail referred to as in-store ubiquitous computing-based information technologies is growing. Yet, little is known about how customers would evaluate such technologies. In this dissertation, a context-specific model for the acceptance of the in-store ubiquitous computing-based information services is developed. UTAUT2 is modified and extended by germane user, service, and technology characteristics. A scenario-based survey study using PLS-SEM method is conducted to test the developed model. The results provide strong empirical support for the proposed model.

Optimal Control of Brownian Inventory Models with Convex Holding Cost: Average Cost Case

Subjects: subject: Optimization and Control (math.OC)

description: We consider an inventory system in which inventory level fluctuates as a Brownian motion in the absence of control. The inventory continuously accumulates cost at a rate that is a general convex function of the inventory level, which can be negative when there is a backlog. At any time, the inventory level can be adjusted by a positive or negative amount, which incurs a fixed cost and a proportional cost. The challenge is to find an adjustment policy that balances the holding cost and adjustment cost to minimize the long-run average cost. When both upward and downward fixed costs are positive, our model is an impulse control problem. When both fixed costs are zero, our model is a singular or instantaneous control problem. For the impulse control problem, we prove that a four-parameter control band policy is optimal among all feasible policies. For the singular control problem, we prove that a two-parameter control band policy is optimal. We use a lower-bound approach, widely known as "the verification theorem", to prove the optimality of a control band policy for both the impulse and singular control problems. Our major contribution is to prove the existence of a "smooth" solution to the free boundary problem under some mild assumptions on the holding cost function. The existence proof leads naturally to numerical algorithms to compute the optimal control band parameters. We demonstrate that the lower-bound approach also works for Brownian inventory model in which no inventory backlog is allowed. In a companion paper, we will show how the lower-bound approach can be adapted to study a Brownian inventory model under a discounted cost criterion.

description: Applied ontology is a relatively new field which aims to apply theories and methods from diverse disciplines such as philosophy, cognitive science, linguistics and formal logics to perform or improve domain-specific tasks. To support the development of effective research methodologies for applied ontology, we critically discuss the question how its research results should be evaluated. We propose that results in applied ontology must be evaluated within their domain of application, based on some ontology-based task within the domain, and discuss quantitative measures which would facilitate the objective evaluation and comparison of research results in applied ontology.

description: Spherical symmetry for f(R)-gravity is discussed by searching for Noether symmetries. The method consists in selecting conserved quantities in form of currents that reduce dynamics of f(R)-models compatible with symmetries. In this way we get a general method to obtain constants of motion without setting a priori the form of f(R). In this sense, the Noether symmetry results a physical criterium. Relevant cases are discussed.

description: Recently it was shown that vacuum in a background of strong enough magnetic field becomes an electromagnetic superconductor due to interplay between strong and electromagnetic forces. The superconducting ground state of the vacuum is associated with a spontaneous emergence of quark-antiquark condensates which carry quantum numbers of charged rho mesons. The rho-meson condensate is an inhomogeneous structure made of the so-called rho vortices, which are parallel to the magnetic field axis. The condensation of the charged rho mesons induces a (much weaker) superfluid-like condensate with quantum numbers of the neutral rho mesons. In this paper we show that the vortices in the superconducting condensate organize themselves in an equilateral triangular lattice similarly to an ordinary type-II superconductor. We show that each of these superconductor vortices is accompanied by three superfluid vortices and three superfluid antivortices made of the neutral rho meson condensate. The superconductor vortex overlaps with one of the superfluid vortices. The superposition of the superconducting and superfluid vortex lattices has a honeycomb pattern.

description: Cognitive radio (CR) is a novel approach to improving the spectral efficiency of licensed radio frequency bands by opportunistically accessing unused portions of the band without introducing undue interference to a licensed user. To reliably identify unused portions in a dynamic environment, a collaborative spectrum sensing (CSS) approach is known to be advantageous. In this thesis, we investigate two issues related to CSS. A weighted energy fusion scheme for secondary users (SUs) with different sensing channel conditions is shown to achieve good sensing performance. To analyze the performance, a numerical approach utilizing a result in the probability density function of the weighted sum of noncentral chi-square random variables is used. Simulation results confirm the viability of the proposed numerical approach. The performance degradation resulting from imperfect reporting channels and energy measurement quantization in a CSS system is investigated. Simulation results show that the sensing performance can be significantly degraded. To reduce the performance degradation, unequal error protection of transmitted symbols through unequal power allocation (UPA) is employed. Simulation results are provided to quantify the gain provided by UPA.

description: We have obtained Spitzer IRS spectra and MIPS 24, 70, and 160 micron photometry for a volume-limited sample of 22 SDSS-selected Low-ionization Broad Absorption Line QSOs (LoBALs) at 0.5 < z < 0.6. By comparing their mid-IR spectral properties and far-IR SEDs with those of a control sample of 35 non-LoBALs matched in M_i, we investigate the differences between the two populations in terms of their infrared emission and star formation activity. Twenty five percent of the LoBALs show PAH features and 45% have weak 9.7 micron silicate dust emission. We model the SEDs and decouple the AGN and starburst contributions to the far-infrared luminosity in LoBALs and in non-LoBALs. Their median total, starburst, and AGN infrared luminosities are comparable. Twenty percent (but no more than 60%) of the LoBALs and 26% of the non-LoBALs are ultra-luminous infrared galaxies (ULIRGs; L_IR>10^12*L_sun). We estimate star formation rates (SFRs) corrected for the AGN contribution to the FIR flux and find that LoBALs have comparable levels of star formation activity to non-LoBALs when considering the entire samples. However, the SFRs of the IR-luminous LoBALs are 80% higher than those of their counterparts in the control sample. The median contribution of star formation to the total far-infrared flux in LoBALs and in non-LoBALs is estimated to be 40-50%, in agreement with previous results for PG QSOs. Overall, our results show that there is no strong evidence from the mid- and far-IR properties that LoBALs are drawn from a different parent population than non-LoBALs.

description: Observations and theory suggest that star clusters can form in a subvirial (cool) state and are highly substructured. Such initial conditions have been proposed to explain the level of mass segregation in clusters through dynamics, and have also been successful in explaining the origin of trapezium-like systems. In this paper we investigate, using N-body simulations, whether such a dynamical scenario is consistent with the observed binary properties in the Orion Nebula Cluster (ONC). We find that several different primordial binary populations are consistent with the overall fraction and separation distribution of visual binaries in the ONC (in the range 67 - 670 au), and that these binary systems are heavily processed. The substructured, cool-collapse scenario requires a primordial binary fraction approaching 100 per cent. We find that the most important factor in processing the primordial binaries is the initial level of substructure; a highly substructured cluster processes up to 20 per cent more systems than a less substructured cluster because of localised pockets of high stellar density in the substructure. Binaries are processed in the substructure before the cluster reaches its densest phase, suggesting that even clusters remaining in virial equilibrium or undergoing supervirial expansion would dynamically alter their primordial binary population. Therefore even some expanding associations may not preserve their primordial binary population.

Fatigue strength of thermal cut steel edges at sub-zero temperatures

description: Openings in the outer shell of ship structures are typically thermal cut. Thermal cut steel edges have an increased risk for fatigue failure due to their local geometry. Additionally the temperature also effects the fatigue strength of thermal cut edges. Since fatigue crack growth testing of base material had shown that the crack growth can be accelerated at low temperatures the effect of low temperatures on thermal cut edges is of particular interest for the fatigue assessment of cruise ships and large yachts, which operates in seasonal freezing temperatures. However the current guidelines for the fatigue assessment of ship structures do not take the effect of low temperatures on the fatigue performance of thermal cut steel edges into account. In order to investigate whether low temperatures have an influence on the fatigue strength of thermal cut steel edges, fatigue tests of plasma cut specimens at -20°C, -50°C and at room temperature are conducted. The results are then statistically evaluated with linear regression and the maximum likelihood method. Thereby it is found that the fatigue strength increase significantly at the tested sub-zero temperatures compared with room temperature. Accordingly no increased risk to fatigue failure of thermal cut steel edges at sub-zero temperatures were found in this thesis.

description: The confluence of untyped λ-calculus with unconditional rewriting is now well un- derstood. In this paper, we investigate the confluence of λ-calculus with conditional rewriting and provide general results in two directions. First, when conditional rules are algebraic. This extends results of Müller and Dougherty for unconditional rewriting. Two cases are considered, whether β-reduction is allowed or not in the evaluation of conditions. Moreover, Dougherty's result is improved from the assumption of strongly normalizing β-reduction to weakly normalizing β-reduction. We also provide examples showing that outside these conditions, modularity of confluence is difficult to achieve. Second, we go beyond the algebraic framework and get new confluence results using a restricted notion of orthogonality that takes advantage of the conditional part of rewrite rules.

description: Edge localised modes (ELMs) allow maintaining sufficient purity of tokamak H-mode plasmas and thus enable stationary H-mode. On the other hand in a future device ELMs may cause divertor power flux densities far in excess of tolerable material limits. The size of the energy loss per ELM is determined by saturation effects in the non-linear phase of the ELM, which at present is hardly understood. Solitary magnetic perturbations (SMPs) are identified as dominant features in the radial magnetic fluctuations below 100kHz. They are typically observed close (+-0.1ms) to the onset of pedestal erosion. SMPs are field aligned structures rotating in the electron diamagnetic drift direction with perpendicular velocities of about 10km/s. A comparison of perpendicular velocities suggests that the perturbation evoking SMPs is located at or inside the separatrix. Analysis of very pronounced examples showed that the number of peaks per toroidal turn is 1 or 2, which is clearly lower than corresponding numbers in linear stability calculations. In combination with strong peaking of the magnetic signals this results in a solitary appearance resembling modes like palm tree modes, edge snakes or outer modes. This behavior has been quantified as solitariness and correlated to main plasma parameters. SMPs may be considered as a signature of the non-linear ELM-phase originating at the separatrix or further inside. Thus they provide a handle to investigate the transition from linear to non-linear ELM phase. By comparison with data from gas puff imaging processes in the non-linear phase at or inside the separatrix and in the scrape-off-layer (SOL) can be correlated. A connection between the passing of an SMP and the onset of radial filament propagation has been found. Eventually the findings related to SMPs may contribute to a future quantitative understanding of the non-linear ELM evolution.

description: We use rest-frame UV spectroscopy to investigate the properties related to large-scale gas outflows, and to the dust extinction and star-formation rates of a sample of z ~ 2 star-forming galaxies from the Galaxy Mass Assembly ultradeep Spectroscopic Survey (GMASS). Dust extinction is estimated from the rest-frame UV continuum slope and used to obtain dust-corrected star-formation rates for the galaxies of the sample. For the entire sample, a mean value of the continuum slope = -1.11 \pm 0.44 (r.m.s.) was derived, while the average SFR was found to be = 52 \pm 48 M_sun/yr (r.m.s.). A positive correlation between SFR and stellar mass was observed, in agreement with other works, the logarithmic slope of the relation being 1.10 \pm 0.10. Low-ionization absorption lines, associated with the interstellar medium, were found to be blueshifted, with respect to the rest frame of the system, which indicates that there is outflowing gas with typical velocities of the order of ~ 100 km/s. Finally, investigating correlations between galaxy UV spectral characteristics and galaxy general properties, we report a possible correlation between the equivalent width of the interstellar absorption lines and SFR, stellar mass, and colour excess similar to that seen to hold at different redshifts.

Senior nurse involvement in project development : how best to utilize the skills of senior nurses in the workplace
Creators: name: Riedel, Jane Ada
Publisher: name: University of British Columbia
Year: 2009

description: Encouraging senior nurse participation in project development aimed at transferring knowledge from older to younger generations may increase retention of nurses nearing retirement and attract new nurses looking for institutions that offer innovative education and support programs. Senior nurse involvement in project work is not without challenges. Coping with the current nursing shortage and the conflicts of a multi-generational workforce make the design and implementation of senior nurse projects complex. With funding support from the BC Nurses Bargaining Association 12 focus groups were conducted with nurses 55 years of age and older to assess what senior nurses are currently doing and what resources they would need to formalize their project ideas in order to pass on their expertise to others. Participants generated a high level of interest and a number of ideas; such as mentoring programs and strategies to enhance quality and safety in the workplace. Focus group participants also identified current practice facilitators and barriers; such as the need for back-fill to cover time away for project development and implementation. Based on focus group results, this thesis will discuss focus group findings and provide insight on how senior nurses are involved and what potential exists for future development of projects. Senior nurse project work may facilitate the transfer of knowledge from older to younger nurses and increase retention of senior and millennial nurses.
