description: Silicon heterojunction (SHJ) solar cells represent a promising technological approach towards higher photovoltaics efficiencies and lower fabrication cost. While the device physics of SHJ solar cells have been studied extensively in the past, the ways in which nanoscopic electronic processes such as charge-carrier generation, recombination, trapping, and percolation affect SHJ device properties macroscopically have yet to be fully understood. We report the study of atomic scale current percolation at state-of-the-art a-Si:H/c-Si heterojunction solar cells under ambient operating conditions, revealing the profound complexity of electronic SHJ interface processes. Using conduction atomic force microscopy (cAFM), it is shown that the macroscopic current-voltage characteristics of SHJ solar cells is governed by the average of local nanometer-sized percolation pathways associated with bandtail states of the doped a-Si:H selective contact leading to above bandgap open circuit voltages ($V_{\mbox{OC}}$) as high as 1.2 V ($V_{\mbox{OC}}>e E_{\mbox{gap}}^{\mbox{Si}}$). This is not in violation of photovoltaic device physics but a consequence of the nature of nanometer-scale charge percolation pathways which originate from trap-assisted tunneling causing dark leakage current. We show that the broad distribution of local photovoltage is a direct consequence of randomly trapped charges at a-Si:H dangling bond defects which lead to strong local potential fluctuations and induce random telegraph noise of the dark current.

description: The numerically exact evaluation of the van der Waals interaction, also known as Casimir interaction when including retardation effects, constitutes a challenging task. We present a new approach based on the plane-wave basis and demonstrate that it possesses advantages over the more commonly used multipole basis. The rotational symmetry of the plane-sphere and sphere-sphere geometries can be exploited by means of a discrete Fourier transform. The new technique is applied to a study of the interaction between a colloid particle made of polystyrene or mercury and another polystyrene sphere or a polystyrene wall in an aqueous solution. Special attention is paid to the influence of screening caused by a variable salt concentration in the medium. It is found that in particular for low salt concentrations the error implied by the proximity force approximation is larger than usually assumed. For a mercury droplet, a repulsive interaction is found for sufficiently large distances provided screening is negligible. We emphasize that the effective Hamaker parameter depends significantly on the scattering geometry on which it is based.

The social life of things : a case study of the Woodward’s Department Store
Creators: name: Thompson, Lindsay
Publisher: name: University of British Columbia
Year: 2009

description: The objective of this paper is to illustrate how the city came to have such a love affair with the Woodward's Department Store, and how this love affair has led to the building occupying a position of importance in the city of Vancouver. This thesis critically endeavours to argue that Woodward's has become important through the role of social memory, which is able to make and remake the idea of Woodward's, and through the social life of Woodward's objects. Here I use the term social memory to refer to the collective memory that people share about Woodward's, and also to the 'social' way through which this memory is formed. Not only is people's memory of the Woodward's Department Store social, as they remember the 'social'ness of what it meant to either work or shop there, but the objects associated with the building also have a social life, where their function, ownership and meaning have changed over time. Throughout this argument, I attempt to extract the meaning of the memories and memorabilia submitted to the Woodward's Memories Project, in order to outline the reasons why the building holds importance in the city. The story of how Woodward's came to hold such a place of importance in the city can be revealed from the 'social' aspect of both social memory and the social life of objects. Through Woodward's various functions and roles the meanings become entangled, representing the Woodward's building as an object, a memory and an agent of nostalgia. Because Woodward's was an integral part of Vancouver for generations, the store became rooted in the memory of the people and the city as a whole. This is evidenced not only by their memory of the department store but also by the current revitalization efforts of the Downtown Eastside, to which the redevelopment of Woodward's is key. By outlining the social capital of the Woodward's location as a heritage site, as well as of the Woodward's objects and the memories associated with them, one can finally begin to understand the true importance of the Woodward's Department Store to the City of Vancouver. This holds great importance for Vancouver, especially in this time of revitalization and redevelopment. Not only is the past brought to the forefront of a new project, but by tracing the social life of the building the new meanings and functions that the space served is revealed. This research represents a new part of the city's history which is important to document and share with the public. Aiding in understanding the Woodward's building, both in the past and present, the significance of this project extends beyond the scope of this thesis.

description: Due to the recent outbreak of COVID-19, many governments suspended outdoor activities and imposed social distancing policies to prevent the transmission of SARS-CoV-2. These measures have had severe impact on the economy and peoples' daily lives. An alternative to widespread lockdowns is effective contact tracing during an outbreak's early stage. However, mathematical models suggest that epidemic control for SARS-CoV-2 transmission with manual contact tracing is implausible. To reduce the effort of contact tracing, many digital contact tracing projects (e.g., PEPP-PT, DP-3T, TCN, BlueTrace, Google/Apple Exposure Notification, and East/West Coast PACT) are being developed to supplement manual contact tracing. However, digital contact tracing has drawn scrutiny from privacy advocates, since governments or other parties may attempt to use contact tracing protocols for mass surveillance. As a result, many digital contact tracing projects build privacy-preserving mechanisms to limit the amount of privacy-sensitive information leaked by the protocol. In this paper, we examine how these architectures resist certain classes of attacks, specifically DoS attacks, and present BlindSignedIDs, a privacy-preserving digital contact tracing mechanism, which are verifiable ephemeral identifiers to limit the effectiveness of MAC-compliant DoS attacks. In our evaluations, we showed BlindSignedID can effectively deny bogus EphIDs, mitigating DoS attacks on the local storage beyond 90% of stored EphIDs. Our example DoS attacks showed that using 4 attackers can cause the gigabyte level DoS attacks within normal working hours and days.

description: Weeds can cause significant problems to natural ecosystems. Although there have been numerous studies on the economics of weed control, relatively few of these studies have focused on natural ecosystems. This paper addresses this gap in the literature by assessing the cost-effectiveness of a comprehensive range of control strategies for blackberry (Rubus anglocandicans) in natural environments in Australia. We developed a stochastic dynamic simulation model and a deterministic dynamic optimisation model. The stochastic model calculates the expected net present value (NPV) of a range of control strategies, including any combination of treatment options. The optimisation model identifies the treatment combination that maximises NPV. Both models represent the costs and efficacies of control options over 25 years. The results indicate that using rust (Phragmidium violaceum) as a biological control agent only marginally increases NPV and excluding rust does not affect the optimal choice of other control options. The results also show for a wide range of parameter values that a strategy which combines the herbicide grazon (Triclopyre and picloram) and mowing is optimal. If chemical efficacy decreases by 20 percent it becomes optimal to include grazing blackberry by goats in the control strategy.

description: The nonequilibrium excitonic insulator (NEQ-EI) is an excited state of matter characterized by a finite density of coherent excitons and a time-dependent macroscopic polarization. The stability of this exciton superfluid as the density grows is jeopardized by the increased screening efficiency of the looser excitons. In this work we put forward a Hartree plus Screened Exchange HSEX scheme to predict the critical density at which the transition toward a free electron-hole plasma occurs. The dielectric function is calculated self-consistently using the NEQ-EI polarization and found to vanish in the long-wavelength limit. This property makes the exciton superfluid stable up to relatively high densities. Numerical results for the MoS$_{2}$ monolayers indicate that the NEQ-EI phase survives up to densities of the order of $10^{12}\mathrm{cm}^{-2}$.

description: (Abridged) We revisit the problem of parameter estimation of gravitational-wave chirp signals from inspiralling non-spinning compact binaries in the light of the recent extension of the post-Newtonian (PN) phasing formula to order $(v/c)^7$ beyond the leading Newtonian order. We study in detail the implications of higher post-Newtonian orders from 1PN up to 3.5PN in steps of 0.5PN ($\sim v/c$), and examine their convergence. In both initial and advanced detectors the estimation of the chirp mass (${\cal M}$) and symmetric mass ratio ($η$) improve at higher PN orders but oscillate with every half-a-PN order. We compare parameter estimation in different detectors and assess their relative performance in two different ways: at a {\it fixed SNR,} with the aim of understanding how the bandwidth improves parameter estimation, and for a {\it fixed source}, to gauge the importance of sensitivity. Errors in parameter estimation at a fixed SNR are smaller for VIRGO than for both initial and advanced LIGO. However, for sources at a fixed distance it is advanced LIGO that achieves the lowest errors owing to its greater sensitivity. Finally, we compute the amplitude corrections due to the `frequency-sweep' in the Fourier domain representation of the waveform within the stationary phase approximation and discuss its implication on parameter estimation.

description: Regression analyses show that the relationship between various resource footprints and quality of life generally follows a logarithmic path of development, while resource footprints and GDP per capita are linearly connected. Departing from the path of development and its development clusters, the concepts of decoupling, planetary and social boundaries can be added, showing that decoupling and green growth might not be sufficient to achieve environmentally sustainable development (ESD), if planetary boundaries have already been transgressed. Accordingly, a new model of ESD has been developed, supporting the concepts of a-growth and post-growth, which can be utilized as point of departure for further research towards a new, more comprehensive model. Development clusters along the path of development can be utilized for SDG prioritization and to adopt environmentally differentiated CDM strategies.

description: On the basis of expounding farmers’ behaviors on agricultural technology inputs studied by the foreign scholars; relying on the investigation data of 276 rural households in Deyang City, Sichuan Province and by using the Logistic Regression model, the farmers’ behaviors on agricultural technology inputs and the influencing factors on their behaviors are analyzed. The results show the main factors that influence farmers; behaviors on agricultural inputs are whether they have the assistance of agricultural technology personnel; the choices of plantation; non-agricultural income; area of land management; the expectation on land ownership, whether it has township enterprises and the proportion of the non-agricultural labor forces and some other factors. The influencing degree of these factors descends from strong to weak. On the strength of the study results, the countermeasures on increasing local farmers’ inputs on agricultural technology are put forward from the aspects of stabilizing rural land property, establishing scientific land transfer mechanism and intensifying the governmental functions of agro-technical station.

description: Economic complexity indicators, which aim to infer the knowledge and capabilities within countries and regions, have become increasingly prominent in the economic geography literature, as well as on policy recommendations across several different geographical and socioeconomic contexts. Such applications often lack a critical understanding of what economic complexity encompasses and its applicability to different contexts. It is therefore crucial to understand what economic complexity captures, and where and when it should be applied, as well as to have a more grounded understanding of its conceptual shortcomings. This thesis contributes towards closing this gap in the literature and provides a critical evaluation of the economic complexity concept and measure for regional economic development. Structured along four chapters, the thesis provides, firstly, a critical survey of the economic complexity literature and explores the export-based complexity index at the country-level – this is the basis for the next chapters, which address key empirical issues. Moving to the sub-national level and using employment data, the second chapter explores occupation complexity across Portuguese municipalities – here, we analyse the applicability of the economic complexity index to occupation and industry data and explore the policy lessons and implications for regional growth and development. The third chapter focuses on export-based economic complexity and natural resource dependence, where we investigate what the index captures in countries with a very high dependence on oil and whether it is associated with economic growth, with a focus on the Gulf Cooperation Council countries. Lastly, the fourth chapter provides an exploratory empirical analysis, with a focus on the links between economic complexity, education and economic growth across countries, followed by a concluding reflection on the thesis findings. Overall, this thesis provides evidence that economic complexity indicators capture distinctive aspects across different geographical levels and types of data, unlike what some of the existing literature implies. Our findings call for more caution in empirical work, particularly for policy-making purposes – the definition of economic complexity across applications to different types of data and to unique socioeconomic contexts should be carefully considered, and any economic development policy based on this top-down indicator crucially requires consideration of local conditions.

description: We present a simple proof of the approximate Eastin-Knill theorem, which connects the quality of a quantum error-correcting code (QECC) with its ability to achieve a universal set of transversal logical gates. Our derivation employs powerful bounds on the quantum Fisher information in generic quantum metrological protocols to characterize the QECC performance measured in terms of the worst-case entanglement fidelity. The theorem is applicable to a large class of decoherence models, including independent erasure and depolarizing noise. Our approach is unorthodox, as instead of following the established path of utilizing QECCs to mitigate noise in quantum metrological protocols, we apply methods of quantum metrology to explore the limitations of QECCs.

description: We report the results of extensive high-energy observations of the X-ray transient and black hole candidate XTE J1720-318 performed with INTEGRAL, XMM-Newton and RXTE. The source, which underwent an X-ray outburst in 2003 January, was observed in February in a spectral state dominated by a soft component with a weak high-energy tail. The XMM-Newton data provided a high column density Nh of 1.2*e22 cm^{-2} which suggests that the source lies at the Galactic Centre distance. The simultaneous RXTE and INTEGRAL Target of Opportunity observations allowed us to measure the weak and steep tail, typical of a black-hole binary in the so-called High/Soft State. We then followed the evolution of the source outburst over several months using the INTEGRAL Galactic Centre survey observations. The source became active again at the end of March: it showed a clear transition towards a much harder state, and then decayed to a quiescent state after April. In the hard state, the source was detected up to 200 keV with a power law index of 1.9 and a peak luminosity of 7*e36 erg s^{-1} in the 20-200 keV band, for an assumed distance of 8 kpc. We conclude that XTE J1720-318 is indeed a new member of the black hole X-ray novae class which populate our galactic bulge and we discuss its properties in the frame of the spectral models used for transient black hole binaries.

description: The three-period (1995, 1998 and 2003) remote sensing images in Jinan City, China are selected. And the information of green land, construction land, woodland and water body is extracted by using the image processing module of remote-sensing software and computerized interpretation module. Both the change table and transfer matrix table of land use area are analyzed by modeling module of remote-sensing software. Then, the Geo-information Tupu is obtained; and the temporal and spatial variation of land use in Jinan City is monitored and analyzed by Geo-information Tupu and transfer matrix. Result shows that land use structure change of Jinan City in the years 1995-1998 shows a transformation from green land to construction land. Area of green land circulating into construction land reaches 62.27 square kilometers, accounting for 25.84% of the initial green land. In the year 1998, areas of woodland and green land are reduced due to the urban expansion of Jinan City. However, with the enhancement of people's awareness of environmental protection, areas of woodland and green land gradually increase in the year 2003, which are still less than those in the year 1995.

description: The forthcoming Versatile Video Coding (VVC) standard adopts the trellis-coded quantization, which leverages the delicate trellis graph to map the quantization candidates within one block into the optimal path. Despite the high compression efficiency, the complex trellis search with soft decision quantization may hinder the applications due to high complexity and low throughput capacity. To reduce the complexity, in this paper, we propose a low complexity trellis-coded quantization scheme in a scientifically sound way with theoretical modeling of the rate and distortion. As such, the trellis departure point can be adaptively adjusted, and unnecessarily visited branches are accordingly pruned, leading to the shrink of total trellis stages and simplification of transition branches. Extensive experimental results on the VVC test model show that the proposed scheme is effective in reducing the encoding complexity by 11% and 5% with all intra and random access configurations, respectively, at the cost of only 0.11% and 0.05% BD-Rate increase. Meanwhile, on average 24% and 27% quantization time savings can be achieved under all intra and random access configurations. Due to the excellent performance, the VVC test model has adopted one implementation of the proposed scheme.

Community food security and the landscape of cities
Creators: name: Hohenschau, David Lea
Publisher: name: University of British Columbia
Year: 2009

description: Community food security is a framework for community development that engages the sustainability of the local food system and the equitable distribution of food resources. This project suggests a community food design program that optimizes the potential for a sustainable and equitable local food system, and applies it to the Renfrew Collingwood community in Vancouver, British Columbia. The basic principles of the program require equitable access to food distribution and the allocation of land for food production. The applied program is described as a community design plan, and suggests that with minimal changes to the patterns of land use, and significant changes to the use of the public landscape, such a system would support a food sufficiency rate of 5 to 20 percent.

description: We study the Ginzburg-Landau equations of super-conductivity describing the experimental setup of a Stiffnessometer device. In particular, we consider the nonlinear regime which reveals the impact of the superconductive critical current on the Stiffnessometer signal. As expected, we find that at high flux regimes, superconductivity is destroyed in parts of the superconductive regime. Surprisingly, however, we find that the superconductivity does not gradually decay to zero as flux increases, but rather the branch of solutions undergoes branch folding. We use asymptotic analysis to characterize the solutions at the numerous parameter regimes in which they exist. An immediate application of the work is an extension of the regime in which experimental measurements of the Stiffnessometer device can be interpreted.

description: In this paper, we comparitvley studied acetic acid attacks on geopolymer (GP-M), calcium aluminate (CAC-M), and Portland cement (PC-M)-based mortars. Consequent formations of deteriorated or transition layers surrounding the unaltered core material was classified in these three mortars, according to different degradation levels depending on what binder type was involved. Apart from mass loss, hardness, and deterioration depth, their microstructural alterations were analyzed using test methods such as scanning electron microscopy with energy dispersive spectroscopy (SEM-EDS), mercury intrusion porosimetry (MIP), powder X-ray diffraction (XRD), and thermogravimetric analysis-differential scanning calorimeter (TGA-DSC), which showed the different mechanisms for each binder type. Elemental maps revealed the decalcification (PC-M and CAC-M) and depolymerization (GP-M) that occurred across the mortar sections. The mass loss, hardness, and porosity were the least affected for GP-M, followed by CAC-M. These results points out that geopolymer-based mortars have improved acid resistance, which can be used as a potential alternative to conventional cement concretes that have been exposed to agro-industrial environments.

description: This thesis focuses on raising public and political awareness regarding the consequences of radon in Africa and has two major purposes: the first is to provide an in-depth analysis of the position of institutions such as the EU and the AU and their role in respect to the lack of awareness of the consequences of radon exposure; the second is to find out whether and how can a better understanding of the consequences of indoor radon exposure in Africa be achieved. The hypotheses include that awareness of radon is dependent on the peoples education concerning the environment and the consequences of radon. The data used and accessed through the database Factiva were obtained from EU and AU documents as well as scholarly literature dealing with radon exposure and lung cancer in Africa. In the first part, the scholarly literature is discussed which deals with radon and lung cancer in developing countries as well as Africas growing lung cancer problem due to environmental and occupational issues. In the second part, the situation in the EU and the AU is analyzed regarding the publics protection from radon exposure in workplaces and dwellings. Furthermore, possible and potential channels are discussed to raise public and political awareness of the consequences of radon in Africa. The outcome of the thesis is that this lack of awareness has been manifested through the lack of education regarding health effects due to radon. However, the results suggest that education is not enough to acknowledge radon as a threat to public health. Thus, a more emphatic engagement that goes beyond education and scientific support is needed. The amplification of a political will to acknowledge radon as a threat to public health can lead to lengthy procedures. This research serves as a basis to conduct a pilot project and fieldwork in Africa.
Research of the farmland protection based on food security —A case study of Anshan City in Liaoning Province, China

description: The quantity and quality of farmland is the key factor determining grain production capacity, so protecting farmland has become the key to guaranteeing food security. I take Anshan City in Liaoning Province as the study area which has its own particularity in terms of protecting farmland. Based on the prediction of population, coupled with the relevant data concerning farmland area, the per unit area yield of grain, the prediction and analysis of the balance of supply and demand of farmland in Anshan City are conducted. The results show that in the year 2010, the maximum supply amount of farmland that the city can offer is 239000 hm2, and in the year 2020 the maximum supply amount of farmland that the city can offer will be 238000hm2; in the year 2010, the maximum demand amount of farmland is 204186.02 hm2, and in the year 2020 the maximum supply amount of farmland will be 226409.61hm2. So the supply amount of farmland that the city can offer can meet the need of grain production objective. Some problems concerning farmland protection are pointed out in order to provide beneficial exploration of the farmland protection based on the model of food security.

description: This manuscript describes the commissioning of the Mini-CAPTAIN liquid argon detector in a neutron beam at the Los Alamos Neutron Science Center (LANSCE), which led to a first measurement of high-energy neutron interactions in argon. The Mini-CAPTAIN detector consists of a Time Projection Chamber (TPC) with an accompanying photomultiplier tube (PMT) array sealed inside a liquid-argon-filled cryostat. The liquid argon is constantly purified and recirculated in a closed-loop cycle during operation. The specifications and assembly of the detector subsystems and an overview of their performance in a neutron beam are reported.

description: This master thesis focuses on the implementation of energy efficiency in Austria. For that, the EU Energy Efficiency Directive and the Austrian Energy Efficiency Act were analyzed as well as the role of energy efficiency in the Austrian climate and energy strategy #mission 2030. This thesis further examines energy efficiency in companies by looking into the status of energy audits. In order to get decent results, a thorough literature review was conducted together with expert interviews in the field of energy audits. The results show that energy efficiency plays a major role in decarbonization, which is the headline goal for the EU until 2050 and also in the Austrian climate and energy strategy #mission 2030. There are especially energy efficiency potentials in the mobility and buildings sectors and thus this thesis also looks into these fields in particular. In terms of energy efficiency in companies, energy audits are a tool to increase energy efficiency within companies. It was found that the proposed energy efficiency measures are largely implemented by companies, however there is still potential for improvements not only in obligated, large companies but in several fields in Austria.
