Evaluation of acid production potential of mining waste materials: laboratory and pilot plant procedures
Creators: name: Bruynesteyn, A.

Publisher: name: The University of British Columbia
Year: 2009

description: From the foregoing description of waste material testing, it is apparent that any testing program should be carefully designed to incorporate variations in waste characteristics and climatic conditions, as well as waste dump configuration and dump construction methods. The results of a properly executed test program can be used to prevent or minimize the quantity of acid effluent produced and can have a significant effect on the cost of the necessary effluent treatment facilities by preventing over-design.

description: We study the decrease of fluctuations of diagonal matrix elements of observables and of Husimi densities of quantum mechanical wave functions around their mean value upon approaching the semi-classical regime ($\hbar \rightarrow 0$). The model studied is a spin (SU(2)) one in a classically strongly chaotic regime. We show that the fluctuations are Gaussian distributed, with a width $σ^2$ decreasing as the square root of Planck's constant. This is consistent with Random Matrix Theory (RMT) predictions, and previous studies on these fluctuations. We further study the width of the probability distribution of $\hbar$-dependent fluctuations and compare it to the Gaussian Orthogonal Ensemble (GOE) of RMT.

description: The general aim of this project was to contribute to the work being done at the Laser Physics Centre in the Research School of Physical Sciences and Engineering in their quest to build a quantum computer. Perturbations on the decoherence time were studied with a number of different methods. These exerimental methods were also theoretically modeled. It was found that in no cases was there a clear change above the uncertainties set by experimental errors, however upper bounds were able to be determined. Optical perturbation of the crystal was found to have an upper interaction strength of 40Hz, while the upper bound on the electric dipole-dipole interaction is 2Hz. Raman echoes were achieved for the first time in this lab and have the longest reported coherence time due to an applied magnetic field.

description: The theory of controlled mechanical systems of [6, 3, 4] is extended to the case of ideal incompressible fluids consisting of charged particles in the presence of an external magnetic field. The resulting control is of feedback type and depends on the Eulerian state of the controlled system. Moreover, the control is set up so that the corresponding closed loop equations are Lie-Poisson. This implies that the energy-momentum method of [1, 11] can be used to find a stabilizing control. As an example the case of planar parallel shear flow with an inflection point is treated. A state dependent feedback control is constructed which stabilizes the system for an arbitrarily long channel.

description: This paper focuses on the covariance-based activity detection problem in a multi-cell massive multiple-input multiple-output (MIMO) system. In this system, active devices transmit their signature sequences to multiple base stations (BSs), and the BSs cooperatively detect the active devices based on the received signals. While the scaling law for the covariance-based activity detection in the single-cell scenario has been extensively analyzed in the literature, this paper aims to analyze the scaling law for the covariance-based activity detection in the multi-cell massive MIMO system. Specifically, this paper demonstrates a quadratic scaling law in the multi-cell system, under the assumption that the path-loss exponent of the fading channel $γ> 2.$ This finding shows that, in the multi-cell massive MIMO system, the maximum number of active devices that can be correctly detected in each cell increases quadratically with the length of the signature sequence and decreases logarithmically with the number of cells (as the number of antennas tends to infinity). Moreover, in addition to analyzing the scaling law for the signature sequences randomly and uniformly distributed on a sphere, the paper also establishes the scaling law for signature sequences based on a finite alphabet, which are easier to generate and store. Finally, this paper proposes two efficient accelerated coordinate descent (CD) algorithms with a convergence guarantee for solving the device activity detection problem. The first algorithm reduces the complexity of CD by using an inexact coordinate update strategy. The second algorithm avoids unnecessary computations of CD by using an active set selection strategy. Simulation results show that the proposed algorithms exhibit excellent performance in terms of computational efficiency and detection error probability.

description: In [{\em Generalized centers of finite sets in Banach spaces}, Acta Math. Univ. Comenian. (N.S.) {\bf 66}(1) (1997), 83--115], Veselý developed the idea of generalized centers for finite sets in Banach spaces. In this work, we explore the concept of {\it restricted $\mr{F}$-center property} for a triplet $(X,Y,\mc{F}(X))$, where $Y$ is a subspace of a Banach space $X$ and $\mc{F}(X)$ is the family of finite subsets of $X$. In addition, we generalize the analysis to include all closed, bounded subsets of $X$. Similar to how Lindenstrauss characterized $n.2.I.P.$, we characterize $n.X.I.P.$. So, it is possible to figure out that $Y$ has $n.X.I.P.$ in $X$ for all natural numbers $n$ if and only if $\tr{rad}_Y(F)=\tr{rad}_X(F)$ for all finite subsets $F$ of $Y$. It then turns out that, for all continuous, monotone functions $f$, the $f$-radii viz. $\tr{rad}_Y^f(F),\tr{rad}_X^f(F)$ are same whenever the generalized radii viz. $\tr{rad}_Y(F), \tr{rad}_X(F)$ are also same, for all finite subsets $F$ of $Y$. We establish a variety of characterizations of central subspaces of Banach spaces. With reference to an appropriate subfamily of closed and bounded subsets, it appears that a number of function spaces and subspaces exhibit the restricted weighted Chebyshev center property.

description: Much research regarding quantum adiabatic optimization has focused on stoquastic Hamiltonians with Hamming symmetric potentials, such as the well studied "spike" example. Due to the large amount of symmetry in these potentials such problems are readily open to analysis both analytically and computationally. However, more realistic potentials do not have such a high degree of symmetry and may have many local minima. Here we present a somewhat more realistic class of problems consisting of many individually Hamming symmetric potential wells. For two or three such wells we demonstrate that such a problem can be solved exactly in time polynomial in the number of qubits and wells. For greater than three wells, we present a tight binding approach with which to efficiently analyze the performance of such Hamiltonians in an adiabatic computation. We provide several basic examples designed to highlight the usefulness of this toy model and to give insight into using the tight binding approach to examining it, including: (1) adiabatic unstructured search with a transverse field driver and a prior guess to the marked item and (2) a scheme for adiabatically simulating the ground states of small collections of strongly interacting spins, with an explicit demonstration for an Ising model Hamiltonian.

description: Objective: The objective of this study is to identify the role of working conditions as predictors of sleepiness while driving among truck drivers. Methods: This was a cross-sectional study carried out among truck drivers who transported grains to Paranaguá Port, Paraná, Brazil. The truck drivers were interviewed and completed a self-administered questionnaire to collect data on sociodemographic and behavioral variables, working conditions, consumption of illicit psychoactive substances, and sleep patterns. Drivers were considered to be sleepy while driving if they reported a medium or high probability of napping while driving at night, during the daytime, or while stopped in traffic. The statistical analysis used logistic regression models progressively adjusted for age, behavioral variables, sleep duration, and other working conditions. Results: In total, 670 male drivers, with a mean age of 41.9 (±11.1) years, were enrolled. The prevalence of sleepiness while driving was 31.5%. After model adjustments, the following working conditions were associated with sleepiness while driving: Distance from the last shipment of more than 1,000 km (odds ratio [OR] = 1.54; 95% confidence interval [CI], 1.07–2.23) and a formal labor contract with a productivity-based salary (OR = 2.65; 95% CI, 1.86–3.78). Consumption of illicit psychoactive substances (OR = 1.99; 95% CI, 1.14–3.47) was also associated with sleepiness while driving. Conclusions: Distance traveled and a formal labor contract with productivity-based earnings were the working conditions associated with sleepiness while driving, regardless of other working or behavioral characteristics, age, consumption of illicit psychoactive substances, and sleep duration.

description: Samples were prepared by performing phosphorus diffusions with POCl3 on Sb doped (100) silicon wafers. 99.9% (3N) purity Al or 99.999% (5N) purity Al dots of diameter 0.7 mm and thickness between 0.2 µm or 1.0 µm were then deposited onto quarters of these wafers. The quarters were then subsequently cleaved into 1 cm2 pieces which were annealed at temperatures ranging from 400?C to 650?C for durations of time between 10 minutes and 2 hours. The speed with which these samples were cooled was also varied. After annealing, 3N Al or 5N Al was then deposited on the rear of the samples to a thickness of 1 µm to ensure a low resistance ohmic contact was formed on the rear. Characterisation of these contacts was carried out by measuring the IV characteristics of the contacts and by removing the Al from the front and making observations of the surface topology under an optical microscope and/or by utilizing a scanning electron microscope (SEM). Also, secondary ion mass spectrometry (SIMS) was used to check the diffusion profile of Al, P, and the concentration of Sb dopant in the wafers. Results showed that samples which had 0.3 µm Al deposited in dots on the front, when sintered at temperatures over the eutectic temperature, exhibited rectifying properties evidenced by IV curves characteristic of diodes with turn on voltages of 0.6 mV. The corresponding samples with 1.0 µm appeared to have similar IV curves. However, the turn on voltage was about 0.5 mV. On inspection of the interface, the 0.3 µm Al deposited samples appeared to have formed large, well rounded holes in the silicon and the 1.0 µm Al deposited samples showed localized spiking and no large, well rounded holes. The samples that were sintered at less than the eutectic temperature, showed very poor rectifying contact properties in their IV curves and their interfaces varied from minimal pitting at lower temperatures to large degrees of pitting at higher temperatures.

description: The article deals with the “Farm to Fork” Strategy, which is the European Union document significant for the future of the Common Agricultural Policy and the effects of its implementation for the beef sector in Poland, as well as an important element of agri-food exports. The analysis uses a “desk research” study to consider the EU legal acts and strategic documents (including CAP Strategic Plan), as well as documents of Eurostat, international organizations (FAO, OECD), and industry organizations. The analysis was performed using an expert method. The study was limited to four groups of issues: greenhouse gas emissions, eco-schemes, antibiotics, and animal welfare. It was concluded that the actions specified in the strategy aimed at considering external costs of food production (particularly health and environmental) would inevitably result in an increase in its prices, because, according to the analyses, the costs even exceed the market value of food. So far, they have been covered by taxpayers, consumers, and other entities. In this situation, according to the Commission, it seems justified to gradually abandon the cheap food policy, which is justified in poorer countries.

description: Knowledge of free-energy differences for states of a system provides an essential component in understanding many processes, including solubility, reaction rates, and phase changes. Therefore, the development of efficient, accurate free-energy calculation routines has long been of interest within the field of molecular modelling. Until recently, thermodynamic integration, free-energy perturbation and slow-change techniques were the only approaches available for the calculation of free-energy differences between two states of a system. However, with the discovery of non-equilibrium free-energy relations in the late nineties, new calculation approaches are now possible. This thesis demonstrates the application of these new relations by deriving them from statistical mechanical concepts and applying them to a variety of systems. Although other types of systems are considered, the focus of this work is on the investigation of density changes, as the density of a system is one of its fundamental intrinsic properties, and expansion and compression phenomena are central to many thermodynamic investigations. To investigate the convergence properties of the free-energy calculation methods prior to their application to systems undergoing a density change, a novel transformation between Lennard-Jones systems possessing different potentials is developed and simulations are completed for a variety of transformation parameters. In particular, the accuracy of free-energy calculations as a function of transformation rate is considered, along with a detailed analysis of free-energy convergence as a function of the number of transformations completed.

description: CO spectral line formation in the Sun was modelled using realistic, ab initio, timedependent 3D radiative-hydrodynamical model atmospheres. Three `phases' of 3D model atmospheres were utilised. In Phase 1, strong CO lines formed in very high atmospheric layers were modelled using the established model (Asplund et al. 2000b). This produced less than perfect agreement with observed line asymmetries measured in the ATMOS disc-centre solar atlas. The velocity, temperature and density fields were then manually altered during Phase 2 in order to ascertain the reasons for the disagreement with observation during Phase 1. Following reasonably successful reproduction of observed profiles and bisectors in Phase 2, new self-consistent simulations were performed using an updated version of the hydrodynamical code and an extended simulation domain in Phase 3. In this final phase, excellent agreement between observed and synthesisedline profile shapes, depths and bisectors was achieved.
From Rhetoric to Reality: A Look at the Implementation of Transit-Oriented Development Plans Along the Gold Line in Los Angeles County

description: The City of Los Angeles, known for its car dependency, has been making strides to revive public transportation in the city. In addition to transit system expansion and improvement, transit-oriented development (TOD) policy has been enacted throughout the city and county in comprehensive plans, community plans, special zoning ordinances, and the Metro Joint Development Program. TOD in this research is defined as high-density mixed-use development in close proximity to one or more forms of public transportation. The social, economic, and environmental benefits of TOD justify its use as an alternative to traditional auto-oriented development. Although the benefits of TOD are well understood, less can be found in current literature addressing the implementation of such policies. What implementation research that does exist has focused on performance in terms of resulting modal shift and transit ridership. Less research has been done to assess the success of implementation in achieving truly mixed and economically accessible transit neighborhoods.
This study uses policy analysis, data mapping, and site inventory to examine the implementation of TOD policies surrounding phase one of the Metro Gold Line in Los Angeles County, a light-rail line completed July 2003. Analysis focuses on density, mix of land use, and economic accessibility within a quarter-mile radius of eleven light rail stations. Change in these indicators between 2000 and 2010 is evaluated to capture the influence of the line opening in 2003. This thesis provides an assessment of the barriers, opportunities and practical issues affecting the translation of a TOD vision from rhetoric to reality. The findings of this research indicate a positive relationship between the strength of governing TOD policies and ability of the TOD vision to be successfully implemented. However, the findings also highlight the importance of additional socio-political factors in influencing plan implementation. The lessons learned provide constructive guidelines for the implementation of transit-oriented development policies around phase two of the Metro Gold Line, opened 2009.
Microtiming deviations in groove

description: Overview - Much work has and is being done on the topic of timing variation in Western notated art music: see Appendix A to this thesis and ... However, less investigation has been undertaken into microtiming deviations in repetitive musics with globally stable tempo. Such musics are here referred to inclusively as groove musics – some examples are: traditional African drumming; funk; and Latin music. ¶ This thesis presents a theory (the Covert Clock Theory) and proposes a model of the production of musical groove. The computer model presented rests on arguments regarding what constitutes groove, both in a musical sense and - beyond the scope of musicology - in terms of how and why humans produce and respond to groove. ¶ Through the examination of human perception and production of rhythm, I propose to develop a model, based on the Covert Clock Theory, of the generation of microtiming deviations characteristic of groove. Ideally, the model should be intuitively controllable by a musician setting a small number of parameters, and should generate deviation patterns which are musically useful and have similar characteristics to those generated by human musicians. ...

description: The public school system in the Philippines adopted a multilingual policy starting in school year 2012-2013.  Implemented as the Mother Tongue-Based Multilingual Education program, the policy localizes the language of early literacy and instruction, the content of the curriculum, and the support systems.  This signals a shift away from the country’s long history of standardized curriculums with their one-size-fits-all approach and Western, colonial paradigms, and language policies with their preferential treatment of the colonizer’s language (English) and/or national language.  This dissertation describes and assesses how the program was implemented in its first year.  The focus is on resources or capacity to implement the program since the literature on implementation studies identifies the availability of these as a factor affecting the passage from policy to local practice.
      	Using the case study design in qualitative research, one division and two elementary schools under it were purposively selected for this inquiry.  All Grade 1 teachers in the two schools along with their curriculum consultants or instructional leaders (namely, their principal, district supervisor, and the division supervisor) comprised the study participants.  Semi-structured interviews and document review were conducted over a period of one year to generate data.  Theory-generated typologies from the conceptual framework as well as emergent themes or categories from real-life data guided the process of data organization and analysis.
              The findings suggest patterns that tended to reinforce institutional continuities rather than institutional shifts.  Critical resources or capacities for change were not productively provided to the local implementers.  Additionally, the resource or capacity gaps appeared to be underpinned by a lingering command or hierarchical structure.  To get past the weight of this status quo, recommendations are offered. These include policies aimed at strengthening the practice of teacher expertise and instructional leadership, and at modifying the administration of the program to align the school language with the home language.

description: In 2018, Ferrari et al. wrote a paper called "Phase Transition for Infinite Systems of Spiking Neurons" in which they introduced a continuous time stochastic model of interacting neurons. This model has a parameter $γ$, corresponding to the rate of the leaking times of the neurons and, as the title says, it was proven there to present a phase transition phenomenon with respect to this $γ$. Here we prove that this model also exhibit a metastable behavior. By this we mean that if $γ$ is small enough, then the re-normalized time of extinction converges toward an exponential random variable of mean 1 as the number of neurons goes to infinity.

description: The propagation of fluctuations in the velocity potential of an inviscid, irrotational fluid is governed by a wave equation very similar to that governing the propagation of massless scalar fields in curved spacetime. This similarity allows certain fluid systems to be used as experimentally realisable models for objects that cannot be studied under controlled conditions, such as black holes and ultrarelativitsic rotating stars. The analogy applies only to the propagation of fields in a fixed background, not to the behaviour of the background itself. However, even this limited similarity has excited a great deal of interest from researchers, since it suggests that phenomena such as superradiance and Hawking radiation may have analogues in superfluids. In recent years, experimental advances in the creation and manipulation of Bose-Einstein condensates have provided researchers with very low temperature systems possessing a uniquely simple microscopic theory. Furthermore, under certain long-length-scale approximations, Bose-Einstein condensates can be described as classical irrotational inviscid fluids, and therefore can be treated as analogues of appropriate gravitational systems. We present a comprehensive and detailed critical review of the mean-field theory of Bose-Einstein condensates, the conditions under which Bose-Einstein condensates can be treated as an analogue gravity system, the construction of analogue black holes, and several derivations of Hawking radiation and analogue Hawking radiation. The interdisciplinary nature of analogue gravity means that the relevant results are widely scattered in the literature, and we consider this critical review and discussion of the relevant literature to be a central and noteworthy element of the project. We then analyse in detail a recent derivation of analogue Hawking radiation in Bose-Einstein condensates as a consequence of quantum depletion. We elucidate the methodology and the physical meaning of the results by comparison with the derivations of Hawking radiation considered previously, and discuss possible extensions and improvements. We also present an original investigation of analogue superradiance in simple vortices, with the vortex density profile chosen to mimic a realistic vortex in a Bose-Einstein condensate. We find that superradiant amplification occurs and is likely to be significant, but our long-length-scale approximation is of dubious validity near the scattering point.

We find that the spiral-defect-chaos (SDC) attractor which exists for Pr~1 has become unstable. Gradually increasing the temperature difference from below to well above its critical value no longer leads to SDC. A sudden jump of temperature difference from below to above onset causes convection to grow from thermal fluctuations and does yield SDC. However, the SDC is a transient; it coarsens and forms a single cell-filling spiral which then drifts toward the cell wall and disappears.

description: In this paper, we investigate sizeable interference effects between a heavy charged Higgs boson signal produced via $gg\to t\bar b H^-$ (+ c.c.) followed by the decay $H^-\to b\bar t$ (+ c.c.) and the irreducible background given by $gg\to t\bar t b \bar b$ topologies at the Large Hadron Collider (LHC). We show how such effects could spoil current $H^\pm$ searches where signal and background are normally treated separately. The reason for this is that a heavy charged Higgs boson can have a large total width, in turn enabling such interferences, altogether leading to very significant alterations, both at the inclusive and exclusive level, of the yield induced by the signal alone. This therefore implies that currently established LHC searches for such wide charged Higgs bosons require modifications. We show such effects quantitatively using two different benchmark configurations of the minimal realisation of Supersymmetry, wherein such $H^\pm$ states naturally exist.

description: The study of magnetic phenomena in low-dimensional systems has largely explored after the discovery of two-dimensional (2D) magnetic materials, such as CrI3 and Cr2Ge2Te6 in 2017. These materials presents intrinsic magnetic order, overcoming the limitations predicted by the Mermin-Wagner theorem, due to magnetic crystalline anisotropy energy. Among these, CrTe2, a van der Waals 2D magnet, has gather significant interest due to its in-plane anisotropic magnetoresistance (AMR) and high Curie temperature. This study investigates the magnetic field-regulated resistance of CrTe2 monolayers in the context of spintronics applications. Utilizing the zigzag-ordered parameters obtained from prior simulations, we examine how external magnetic fields influence resistance states and control the ON/OFF state of nano-devices. The analysis demonstrates that specific magnetic field configurations, particularly those in the form of (0, 0, Bz), which is out-of-plane directed field, gives a non-zero root mean square resistance, indicating a functional ON state. This provides a novel method for magnetically controlled current regulation in spintronic devices. The experimental results also reveal an interesting spin-flop transition in CrTe2 under a z-directed magnetic field, leading to y-directional magnetization. This phenomenon, combined with the material's robust magnetic properties, positions CrTe2 as a promising candidate for next-generation memory and logic devices. By advancing the understanding of magnetic field manipulation in 2D magnetic materials, this research opens new pathways in the development of energy-efficient spintronics technology.

description: If atom lasers are to transform many fields of physics, as well as find applications in industry, the most essential development needed is increased atom flux. In this thesis we report on the experimental observation of fundamental limits on the flux of continuous atom lasers. The flux produced by the commonly used radio frequency outcoupler, can not be arbitrarily increased by increasing the strength of the outcoupling. Above a critical Rabi frequency, the atom laser shows large classical density fluctuations, due to coupling between the multiple Zeeman states. In our system this critical Rabi frequency is about 1 kHz. Futhermore, at large coupling strengths (> 4 kHz for our experimetnal parameters), the continuous atom laser output completely switches off, as a result of the atoms remaining trapped in a bound state. In addition to the investigations of the radio frequency outcoupler, we have demonstrated the first continuous Raman outcoupled atom laser. Preliminary data indicates that the Raman outcoupler will be flux limited in a similar way to the radio frequency outcoupler.

description: The anomalous scaling behavior of the n-th order correlation functions ${\cal F}_n$ of the Kraichnan model of turbulent passive scalar advection is believed to be dominated by the homogeneous solutions (zero-modes) of the Kraichnan equation $\hat{\cal B}_n {\cal F}_n=0$. Previous analysis found zero-modes in perturbation theory in a small parameter. We present non-perturbative analysis of the simplest (non-trivial) case of n=3 and compare the results with the perturbative predictions.

description: Based on the scenario that a $\bar{K} N N$ bound state is generated and it eventually decays into $Λp$, we calculate the cross section of the $K^{-} {}^{3} \text{He} \to Λp n$ reaction, which was recently measured in the J-PARC E15 experiment. We find that the behavior of the calculated differential cross section $d ^{2} σ/ d M_{Λp} d q_{Λp}$, where $M_{Λp}$ and $q_{Λp}$ are the $Λp$ invariant mass and momentum transfer in the $(K^{-} , \, n)$ reaction in the laboratory frame, respectively, is consistent with the experiment. Furthermore, we can reproduce almost quantitatively the experimental data of the $Λp$ invariant mass spectrum in the momentum transfer window $350 \text{ MeV} /c < q_{Λp} < 650 \text{ MeV} /c$. These facts strongly suggest that the $\bar{K} N N$ bound state was indeed generated in the J-PARC E15 experiment.

description: In October of 2003, an agreement was signed allowing for the creation of the largest market and reallocation of water in the United States. The Federal Quantification Settlement Agreement (QSA) sought to clarify usage of the Colorado River, which supports 40 million people across 7 states and northern Mexico and serves as the water source for hundreds of thousands of acres of farmland in California alone. Imperial Valley’s agricultural landscape reaches almost every American grocery store, as it produces the majority of domestically harvested vegetables during winter months and plays a vital supply role in producing feed for livestock in California and around the nation. This paper focuses on the response from the agricultural industry and farmworkers to the commodification and reallocation of water between the Imperial Irrigation District and the San Diego County Water Authority. In order to gauge the response, data on field crops, consumptive water usage and farmworker employment was collected from 2001-2011. This period was selected to measure changes because it represents pre-QSA (2001-2002), implementation (2003) and the scaling up of the QSA (2004-2011.) Finally, several interviews were conducted with farmworker advocacy groups and data on farm-related employment was collected in order to gauge the economic and social implications of the QSA. As a result, planning has a stake in the future of this particular region as it is the primary source for domestically harvested winter crops in the United States, calling for the need to bring water consumption by water agencies in-line with the reality of expanding urban populations in Nevada, Arizona and California. As water becomes an increasingly scarce resource, especially for arid regions, the QSA provides policy makers with an example of how the negotiation process works for an uncharted area for American planning, that is a market-based approach to the socially-optimum allocation of water.
