The digital information age and subsequent globalization have caused rapid transformations to the ways in which we communicate and relate to one another. It has almost become guaranteed that one will be working alongside others from different places with different values and backgrounds. However, the education systems in place since the Industrial Revolution have not kept up with the changes in society and the workplace. In the context of an increasingly networked world, education must cross cultures and disciplines to impart real-world wisdom and connections. As such, this paper explores the concept of a cross-cultural, interdisciplinary design workshop as a case study of using cultural immersion, the pressure of real-world stakes, communication gaps, and background dissonance to necessitate bridging and cognitive reconstructing for success. The paper draws from both qualitative and quantitative measures including post-workshop survey, interview, and content analysis of communicative threads to supplement the primary in-the-field observation method. It examines the expectations and emotions of various stakeholders in the process, classifies their actions and reactions, and analyzes the overall effectiveness of the workshop by the varying definitions to its different stakeholders. The workshop was a success in satisfying the motivations of the organizers and participants by creating an enjoyable experience and creating connections. The effectiveness of the workshop was created from the stress and challenge of putting participants in a real-world context with minimal oversight. Participants had to work across differences together with their partners and as a result, also learned design thinking and the value of each other. Even with self-reported negative emotions, the overall response was positive and towards future participation or dissemination.

description: In the last decade, Pd(0) nanoparticles have attracted increasing attention due to their outstanding utility as nanocatalysts in a wide variety of key chemical reactions. Remarkably, it has now been well-recognized that the encapsulation of Pd(0) nanoparticles as catalysts in various porous systems can protect the catalyst from deactivation, facilitate its separation and significantly increase its reusability. Encapsulated Pd(0) nanoparticles have also had great impact on the catalytic process in terms of reactivity and selectivity, through imposing confinement effects. In this review, we have tried to underscore the potential advantages associated with various organic, inorganic and hybrid porous systems, such as dendrimers, silica mesoporous systems, MOFs and zeolites, for Pd(0) encapsulation between 2005-2016 and disclose the role of confinement effects on the promotion of catalytic activity of the Pd(0) encapsulated species, which have been used as catalysts in some important organic transformations such as C-C coupling reactions, hydrogenation and oxidation reactions. The advantages and merits provided and observed using the encapsulated Pd(0) nanoparticles are compared with those of the corresponding conventional species. These qualities, particularly in terms of Pd leaching, reusability and activity, are systematically discussed.
Reconstruction of process topology using historical data and process models
Creators: name: Ongalbayeva, Aigerim
Publisher: name: University of British Columbia
Year: 2017

description: Modern process industries are large and complex. Their units are highly interconnected with each other. If there is an abnormal situation in the process, the faults might propagate from one part of the process to another. To keep the process safe, it is vital to know a causality and connectivity relationship of the process. Alarms control all process variables and let operators know if there is any fault in the process. During a process malfunction, alarms start from a single process variable and quickly propagate to other variables. This leads to alarm flooding showing continuous appearance of alarms in the monitoring panels. During alarm flooding, it is difficult for operators to find the root cause and solve the problem on time. Causality analysis between different variables is one of the methods to avoid alarm flooding. The method helps to provide a process topology based on the process models and data. Process topology is a map that shows how all units and parts of the process are connected; it helps to find root causes of the fault and to predict future abnormalities. There are many techniques for causality detection. Transfer entropy is a popular method of causality detection that is used for both linear and nonlinear systems. The method estimates the variables’ entropy using their probabilities. This thesis focuses on the transfer entropy based on historical data of the Tennessee-Eastman process. The Tennessee-Eastman is a widely used benchmark in process control studies. The thesis aims to detect the causality and connectivity map of the continuous process measurements. Particle filters or Sequential Monte Carlo methods are also considered to approximate density functions of the filtering problem by spreading particles.

description: We propose superfield equations in tensorial N-extended superspaces to describe the N=2,4,8 supersymmetric generalizations of free conformal higher spin theories. These can be obtained by quantizing a superparticle model in N-extended tensorial superspace. The N-extended higher spin supermultiplets just contain scalar and 'spinor' fields in tensorial space so that, in contrast with the standard (super)space approach, no nontrivial generalizations of the Maxwell or Einstein equations to tensorial space appear when N>2. For N=4,8, the higher spin-tensorial components of the extended tensorial superfields are expressed through additional scalar and spinor fields in tensorial space which obey the same free higher spin equations, but that are axion-like in the sense that they possess Peccei-Quinn-like symmetries.

The Renard 65 kimberlites : emplacement-related processes in Kimberley-type pyroclastic kimberlites
Creators: name: Gaudet, Matthew A.
Publisher: name: University of British Columbia
Year: 2017

description: The Renard 65 pipe is located in the Otish Mountains, Quebec, Canada. It is one of nine diamondiferous kimberlite pipes in the ~ 640 Ma Renard cluster and is the largest of four pipes in the Renard Mine reserve. Detailed characterizations of the petrographic and compositional features of these pipe-infilling kimberlite rock types supports their classification into three geological units: Kimb65a, Kimb65b, and Kimb65d. These pipe-infilling kimberlites are interpreted to represent the solidified products of two separate magmatic events: Phase A containing Kimb65a, and Phase B containing Kimb65b and Kimb65d. This research demonstrates that the interclast matrix modal mineralogy (diopside + phlogopite + serpentine) in pyroclastic rock types in the Renard 65 kimberlites are inconsistent with origins by hydrothermal alteration involving hydrous meteoric fluids. Detailed investigation of the reactions between granitic and gneissic crustal xenolith lithologies and their host kimberlites, suggests that reactions occur at both magmatic and subsolidus temperatures involving significant volumetric proportions of xenoliths. The assimilation of crustal xenoliths, and contamination of the kimberlite magmas primarily by Si, are demonstrated to result in enhanced degassing of magmatic volatiles during emplacement and stabilization of the hybrid groundmass assemblage diopside + phlogopite + serpentine over the non hybrid groundmass assemblage calcite + phlogopite + serpentine. It is thus interpreted that the spatial distribution of transitional to Kimberley-type pyroclastic kimberlite rock types, which are characterized by diopside-rich and calcite-poor matrix assemblages as observed in the Renard 65 pipe and other similar pipes, is a function of crustal xenolith distribution in the magma during emplacement. This model not only accounts for the features of Kimberley-type pyroclastic kimberlite rock types, but also the spatial distribution of these rock types in numerous pipes which is often not consistent with lateral textural gradations as has been previously proposed. These results further indicate that the different mineralogy and textures of Fort-à-la-Corne-type pyroclastic kimberlites with respect to Kimberley-type pyroclastic kimberlites may be a consequence of not only the structural controls imparted by the host rock lithology with implications for emplacement-related processes, but also the absence of contamination of the magma by silicic crustal xenoliths.
MYRIAD: A new N-body code for simulations of Star Clusters

description: We present a new C++ code for collisional N-body simulations of star clusters. The code uses the Hermite fourth-order scheme with block time steps, for advancing the particles in time, while the forces and neighboring particles are computed using the GRAPE-6 board. Special treatment is used for close encounters, binary and multiple sub-systems that either form dynamically or exist in the initial configuration. The structure of the code is modular and allows the appropriate treatment of more physical phenomena, such as stellar and binary evolution, stellar collisions and evolution of close black-hole binaries. Moreover, it can be easily modified so that the part of the code that uses GRAPE-6, could be replaced by another module that uses other accelerating-hardware like the Graphics Processing Units (GPUs). Appropriate choice of the free parameters give a good accuracy and speed for simulations of star clusters up to and beyond core collapse. Simulations of Plummer models consisting of equal-mass stars reached core collapse at t~17 half-mass relaxation times, which compares very well with existing results, while the cumulative relative error in the energy remained below 0.001. Also, comparisons with published results of other codes for the time of core collapse for different initial conditions, show excellent agreement. Simulations of King models with an initial mass-function, similar to those found in the literature, reached core collapse at t~0.17, which is slightly smaller than the expected result from previous works. Finally, the code accuracy becomes comparable and even better than the accuracy of existing codes, when a number of close binary systems is dynamically created in a simulation. This is due to the high accuracy of the method that is used for close binary and multiple sub-systems.

description: We consider a semiclassical (large string tension ~ λ^1/2) limit of 4-point correlator of two "heavy" vertex operators with large quantum numbers and two "light" operators. It can be written in a factorized form as a product of two 3-point functions, each given by the integrated "light" vertex operator on the classical string solution determined by the "heavy" operators. We check consistency of this factorization in the case of a correlator with two dilatons as "light" operators. We study in detail the example when all 4 operators are chiral primary scalars, two of which carry large charge J of order of string tension. In the large J limit this correlator is nearly extremal. Its semiclassical expression is, indeed, found to be consistent with the general protected form expected for an extremal correlator. We demonstrate explicitly that our semiclassical result matches the large J limit of the known free N=4 SYM correlator for 4 chiral primary operators with charges J,-J,2,-2; we also compare it with an existing supergravity expression. As an example of a 4-point function with two non-BPS "heavy" operators, we consider the case when the latter are representing folded spinning with large AdS spin and two "light" states being chiral primary scalars.

description: We report on the detection of strongly varying intergalactic HeII absorption in HST/COS spectra of two z~3 quasars. From our homogeneous analysis of the HeII absorption in these and three archival sightlines, we find a marked increase in the mean HeII effective optical depth from tau~1 at z~2.3 to tau>5 at z~3.2, but with a large scatter of 2< tau <5 at 2.7< z <3 on scales of ~10 proper Mpc. This scatter is primarily due to fluctuations in the HeII fraction and the HeII-ionizing background, rather than density variations that are probed by the co-eval HI forest. Semianalytic models of HeII absorption require a strong decrease in the HeII-ionizing background to explain the strong increase of the absorption at z>2.7, probably indicating HeII reionization was incomplete at z>2.7. Likewise, recent three-dimensional numerical simulations of HeII reionization qualitatively agree with the observed trend only if HeII reionization completes at z=2.7 or even below, as suggested by a large tau>3 in two of our five sightlines at z<2.8. By doubling the sample size at 2.7< z <3, our newly discovered HeII sightlines for the first time probe the diversity of the second epoch of reionization when helium became fully ionized.

description: The analysis of turbulent mixing in complex turbulent flows is a challenging task. The effective mixing of entrained fluids to a molecular level is a vital part of the dynamics of turbulent flows, especially when combustion is involved. Turbulent mixing is a three-stage process of entrainment, stirring and diffusion, and the numerical simulation of turbulent mixing has to consider these three different phenomena. To achieve high-fidelity results, time dependent simulations are mandatory.
Novel Design and Integration of Air Conditioning/Thermal Energy Storage with Phase Change Material

Publisher: name: University of Illinois at Chicago
Year: 2020
Subjects: Uncategorized

description: This study evaluates the use of phase change composite (PCC) material, consisting of paraffin (namely, n-Tetradecane) and expanded graphite, as a potential storage medium for cold thermal energy storage (TES) systems to support air conditioning (AC) applications. The PCC-TES system is to be integrated with the vapor compression refrigeration cycle of an AC system. The use of this proposed solid PCC material is novel. The PCC has excellent material and thermal characteristics as compared to ice or chilled water that are predominantly used in commercial TES systems for air cooling applications. This study proposed and tested a hypothesis, which suggests that integrating a conventional AC with a PCC-TES would result in significant benefits concerning compressor size, compressor efficiency, electricity consumed and CO2 emissions. A multi-layer study was thoroughly conducted involving: (1) literature review (2) material characterization (3) experimental work (4) proof of concept simulation (5) numerical modeling (6) real-life implementation evaluation. The study examined several key thermo-physical properties of PCC material. Actual experimental benchtop system has been built and tested. A simulation model using Aspen Plus® was successfully generated to perform overall system-level assessment and proof of concept. The simulation model also compared the use of PCC materials as the energy storage medium versus the use of ice. A detailed numerical model was also successfully built to describe in detail the transient heat transfer problem of a PCC-TES systems exchanging heat with a heat transfer fluid (namely Ethylene Glycol). The actual experimental benchtop validated the analytical/numerical simulation models. The study was wrapped up by addressing real-life implementation of proposed integration between the AC and PCC-TES for hot and humid climate region with high electricity demand.

description: Using mass-selected galaxy samples from deep multiwavelength data we investigate the incidence of close galaxy pairs between z=0.4-2. Many such close pairs will eventually merge, and the pair fraction is therefore related to the merger rate. Over this redshift range the mean pair fraction is essentially constant (evolving as f_pair (1+z)^{-0.4 +/- 0.6}) with about 6+/-1% of massive galaxies having a 1:4 or greater companion within 30h^-1 kpc. Assuming the timescale over which pairs merge is not a strong function of redshift, this implies a similarly constant merger rate (per unit time) out to z=2. Since about three times as much cosmic time passes at z<1 as between z=1-2, this implies that correspondingly more mergers occur in the low-redshift universe. When minor companions (1:10 mass ratio or greater) are included, the pair fraction increases to ~20% and still does not evolve strongly with redshift. We also use a rest-frame color criterion to select pairs containing only quiescent galaxies (major "dry merger" progenitors), and find them to be similarly rare and constant with 4-7% of massive quiescent galaxies exhibiting a nearby companion. Thus, even though other studies find major mergers to be relatively uncommon since z=1, our results suggest that few additional mergers occur in the 1

Development of molecular assays to detect the presence and viability of Phytophthora ramorum and Grosmannia clavigera
Creators: name: Wong, Barbara
Publisher: name: University of British Columbia
Year: 2017

description: In order to determine if living fungi of phytosanitary concern are present in wood or to evaluate the efficacy of treatments, the method of choice is to grow microbes in petri dishes for subsequent identification. However, some fungi are difficult or impossible to grow in cultures, and thus, to validate the effectiveness of existing and emerging wood treatments, a molecular methodology that can detect living fungi and fungus-like organisms is required. RNA-based molecular diagnostic assays were developed to detect the presence of living fungi and fungi-like organisms of phytosanitary concern. Since RNA represents the transcription of genes and can therefore only be produced by living organisms, it provides a marker to determine if an organism is alive. The assays were designed to target genes that are essential to vital processes, then used to assess their presence and abundance through real-time reverse transcription polymerase chain reaction (PCR). A stability analysis was conducted by comparing the RNA to DNA ratio over treatment time. The results illustrated that for treated samples, DNA remained stable over a period of 10 days post treatment, whereas RNA could not be detected after 24 hours for Phytophthora ramorum or 96 hours for Grosmannia clavigera. Therefore, this method provides a reliable way to evaluate viability of organisms following treatments and can have profound impacts on assessing both timber and non-timber forest products of commercial value.

description: We study FRW cosmology for a non-linear modified F(R) Horava-Lifshitz gravity which has a viable convenient counterpart. A unified description of early-time inflation and late-time acceleration is possible in this theory, but the cosmological dynamic details are generically different from the ones of the convenient viable F(R) model. Remarkably, for some specific choice of parameters they do coincide. The emergence of finite-time future singularities is investigated in detail. It is shown that these singularities can be cured by adding an extra, higher-derivative term, which turns out to be qualitatively different when compared with the corresponding one of the convenient F(R) theory.

description: Exploring the mechanism for the formation of consumer purchase intentions of geographical indication agricultural products in the context of live-streaming sales can provide an important reference for brand marketing of geographical indication agricultural products. In this study, in-depth interviews were conducted with consumers of geographical indication agricultural products. Based on grounded theory, open coding, axial coding and selective coding were performed for interview text. At final, 21 concepts, 7 subcategories and 3 main categories were obtained, and a model of the formation mechanism of the purchase intention of geographical indication agricultural products under the background of live-streaming sales was constructed, that is, “consumer cognition-consumer attitude-consumer behavior”. Among them, consumer cognition includes two dimensions: the type of geographical indication agricultural products and the live-streaming appeal strategy, i.e., the personal cognition of consumer and the promotion of live-streaming host’s strategy. Consumer attitude is value perception of consumers, mainly including two dimensions of functional value and emotional value. Consumer behavior is the consumer’s willingness to buy. It has been concluded that the types of geographical indication agricultural products interact with the live-streaming appeal strategies. Through the intermediary of consumers’ value perception, consumers’ purchase intention is generated. Among them, resource-oriented geographical indication agricultural products adopt rational live-streaming appeal strategies, which can enhance the consumer’s perception of functional value, thereby promoting their purchase intention; and cultural and creative geographical indication agricultural products brands adopt perceptual live-streaming appeal strategies, which can enhance the emotional value perception of consumers, thereby promoting their purchase intention.

description: Diffractions are the primary carriers of information about small scale subsurface heterogeneities, such as fractures, faults, karsts and unconformities. However, the several orders of magnitude difference in amplitude between reflections and diffractions make diffraction imaging difficult. Many strategies have been used during processing and migration, but only few studies ever consider the influence of the survey geometry on diffraction imaging. The reason that the acquisition system can be now taken into account is because of the development of Marchenko redatuming. Given the data excited and recorded on the surface, the Marchenko equation can be used to redatum the sources and receivers to any desired position in the subsurface, with only basic prior information about the subsurface velocity and density. This makes the idea of improving diffraction imaging by adapting the survey geometry possible. This study investigates how the depth and the shape of receiver sets influence diffraction imaging. A set of forward modelling results show that different layouts of the geometry do enhance the diffraction imaging and suggest two preferred layouts, receivers located in the subsurface as a line and a semi-circle. Then the Marchenko method is summarized from the literature by theoretically deriving the 1D and 3D Marchenko equations and practically introducing the workflow of Green’s function retrieval. In the final chapter, using data generated from the surface geometry, the Marchenko redatuming is used to move the sources and receivers to the favourable location chosen during the forward modelling. The amplified diffraction imaging results indicate that the whole process we propose in this thesis is feasible.

description: Objective: The aim of this dissertation is to understand which factors are associated with service utilization and additional services needed for home and community-based services overall and within the home for people with intellectual disabilities (ID). Background: People with ID are living in smaller community settings versus larger institutional settings at higher rates each year with the provision of services and supports within the community. These supports are essential in accessing and remaining in the community. Conceptual Framework: Andersen’s Behavioral Model uses a three-pronged approach in understanding service utilization by examining the impact of predisposing, need, and enabling factors. Predisposing factors are demographic characteristics of an individual. Need factors are factors that impact how needed a service is. Enabling factors are “conditions” that allow an individual to meet a need for a service. This dissertation applies a revised understanding of Andersen’s Behavioral Model to determine which factors are associated with home and community-based service utilization and additional services needed. Methods: This research uses secondary data from the National Core Indicators 2015-2016 Adult Consumer Survey. Descriptive statistics were calculated for the independent and outcome variables. Negative binomial regressions were used to determine which factors impacted service utilization and additional services needed. Binary multivariable logistic regression were utilized to determine which factors were associated with received home services, additional home services needed, and receipt of 24-hour paid home support. Results: Notable findings of this research show that minorities fared worse across the outcomes compared to their White counterparts. Older adults had more access to services and less additional services needed. Enabling factors, such as the Balancing Incentive Program and community fiscal effort for IDD services, produced mixed results on outcomes. Need factors such as problem behaviors, level of intellectual disability, and mobility aids were often associated with more services received but also additional services needed. Conclusion: Future research should include enabling factors such as Balancing Incentive Program, waitlists, and institutions that previous research has not considered. Additionally, future research should look at overall services and also specific services, to determine if specific services drive differences within overall services.

description: Taking Yunnan Province as an example, this paper calculated the real integrated land productivity (RILP) of 16 prefectures (cities) in Yunnan Province for the past 11 years (2009-2019), and analyzed its spatial distribution pattern. The research results show that the RILP of the whole Yunnan Province and all prefectures (cities) showed a slow upward trend. Among them, the province’s RILP showed the highest increase in 2019 compared with the previous year; the RILP of all prefectures (cities) in Yunnan Province has significant spatial autocorrelation, showing obvious positive spatial agglomeration characteristics. Based on this, this paper proposes to improve the overall RILP in various regions according to local conditions and formulate countermeasures for coordinated development of various prefectures (cities).
Hopf Maps, Lowest Landau Level, and Fuzzy Spheres

description: This paper is a review of monopoles, lowest Landau level, fuzzy spheres, and their mutual relations. The Hopf maps of division algebras provide a prototype relation between monopoles and fuzzy spheres. Generalization of complex numbers to Clifford algebra is exactly analogous to generalization of fuzzy two-spheres to higher dimensional fuzzy spheres. Higher dimensional fuzzy spheres have an interesting hierarchical structure made of "compounds" of lower dimensional spheres. We give a physical interpretation for such particular structure of fuzzy spheres by utilizing Landau models in generic even dimensions. With Grassmann algebra, we also introduce a graded version of the Hopf map, and discuss its relation to fuzzy supersphere in context of supersymmetric Landau model.

Deformable motion correction and spatial image analysis in positron emission tomography

Publisher: name: University of British Columbia

description: Positron emission tomography (PET) is a molecular imaging modality that allows to quantitatively assess the physiological function of tissues in-vivo. Subject motion during imaging degrades the quantitative accuracy of the data. In small animal imaging, motion is minimized by the use of anesthesia, which interferes with the normal physiology of the brain. This can be circumvented by imaging awake rodents; however, in this case correction for non-cyclic motion with rigid and deformable components is required. In the first part of the thesis, the problem of motion correction in PET imaging of unrestrained awake rodents is addressed. A novel method of iterative image reconstruction is developed that incorporates correction for non-cyclic deformable motion. Point clouds were used to represent the imaged objects in the image space, and motion was accounted by using time-dependent point coordinates. The quantitative accuracy and noise characteristics of the proposed method were quantified and compared to traditional methods by reconstructing projection data from digital and physical phantoms. A digital phantom of a freely moving mouse was constructed, and the efficacy of motion correction was tested by reconstructing the simulated coincidence data from the phantom. In the second part of the thesis, novel approaches to PET image analysis were explored. In brain PET, analysis based on the tracer kinetic modeling (KM) may not always be possible due to the complexity of the scanning protocols and inability to find a suitable reference region. Therefore, the ability of KM-independent shape and texture metrics to convey useful information on the disease state was investigated, based on an ongoing Parkinson's disease study with radiotracers that probe the dopaminergic system. The pattern of the radiotracer distribution in the striatum was characterized by computing the metrics from multiple regions of interest defined using PET and MRI images. Regression analysis showed a significant correlation between the metrics and clinical disease measures (p<0.01). The effect of the region of interest definition and texture computation parameters on the correlation was investigated. Results demonstrate that there is clinically-relevant information in the tracer distribution pattern that can be captured using shape and texture descriptors.
