A simulation study of grain assembly from farm to elevator at six elevator points in Alberta
Creators: name: Groundwater, Richard Austin
Publisher: name: University of British Columbia
Year: 2011

description: The Canadian grain trade is faced with the prospect of change. It is therefore important to analyze the system for current efficiency and for efficiency under alternative configurations of physical facilities, alternative methods of operating, and alternative regulations. This study is concerned with a somewhat narrow subject, that of grain movement from the farm to elevator. Total costs associated with the assembly of grain were estimated at six elevator points: for the current configuration of facilities, after changes in number and capacity of elevators, after changes in farm storage capacity, after changes in hauling distance and truck size, and after changes in elevator location. The technique of simulation was used, and a model was constructed to provide a simulator of the system. The model was by necessity, simple, incorporating data to represent crop production, farm storage cost, ground storage cost, hauling cost, elevator cost, and rail shipments. Each change necessitated an additional computer run to determine the costs resulting from the change. It was concluded that a model using the technique of simulation could be constructed for the entire grain marketing system to capture the essence of the interdependencies. Ten experiments were conducted to estimate the costs associated with alternative configurations. The resulting estimates indicated that the current configuration is inefficient and that lower costs would occur following: (1) reduction in the number of elevators at each point, (2) a reduction in the number of points, (3) a reduction in farm storage capacity, and (4) by an increase in farm truck size. The cost of assembling grain with the current configuration was estimated to be 24.38 cents per bushel. It is possible given the validity of the model to reduce these costs to 13.76 cents per bushel by decreasing the number of elevators at each point, reducing farm storage capacity, and increasing farm truck size. The complete response surface was not mapped because of the great number of potential permutations, hence only ten discrete experiments were completed. However, indications were that one of the more important ways to achieve a lower per bushel cost of assembly is to increase the volume of grain through a fixed capacity country elevator system. It is important to examine these results in terms of the limited scope of the study for not all costs were accounted. That is, there may be external costs to the rest of the economy due to interdependence.

description: Cavity array, with excellent optical capture capability, has received increasing attention for the surface-enhanced Raman spectroscopy (SERS)-active substrates. Here, we proposed molybdenum disulfide (MoS2) nanocavities growing on pyramid Si (PSi) composed of in situ reduced Au nanoparticles (AuNPs), which can form the multiscale cavities (MSCs), and is facile for the couple of the plasmon. We demonstrated that the PSi/MoS2/Au MSCs can serve as highly sensitive, uniform, and stable SERS substrates for rhodamine 6G (R6G), crystal violet, and adenosine triphosphate detection, benefiting from the synergistic effect of the enhanced light trapping and the effective plasmonic couple. The couple of the plasmon in the MSCs is evidently proved by finite-difference time domain simulation, showing the strong electromagnetic field is located around the cavity wall. Moreover, the excellent hydrophobicity of the PSi/MoS2/AuNPs substrate endows it with the ability for the directional monitoring of organic pollutant in a mixture of oil and water. Finally, we demonstrated the MSCs with outstanding photocatalytic performance could achieve the renewable utilization by self-cleaning, which was attributed to the fast electron transfer and effective light absorption. The proposed PSi/MoS2/AuNPs MSC represents a robust mean using the plasmonic metal/semiconductor heterostructure for high-performance SERS sensors and photodegradation.

description: Despite their enormous potential in primary energy saving and emissions reduction, sorption heat transformers are not in practice commercially viable yet. In the past, a good number of commercialization attempts have been discontinued and the remaining players struggle to find a market niche. The units currently marketed are more similar to R&D prototypes than commercial devices and are available at prices which cannot compete with vapor compression systems yet. In conclusion, AHTs have great potential for the decarbonisation of heating and cooling but still suffer from an apparent stage fright, a consequence of a number of technological shortcomings, among which their manufacturing process. In this investigation we have experimentally confirmed that it is possible to manufacture pressure- and vacuum-tight polymer components with commercial 3D printing. This discovery unlocks many of the usual manufacturing limitations which are preventing sorption heat transformers from reaching higher technology readiness levels and allows to reduce the cost of manufacturing of about 3.9 times.
Uncovering the Women in Oceans Eight: Understanding the Trends of the Womens Movement with the Portrayals of Women in Film

Publisher: name: University of Nevada, Las Vegas
Year: 2019

description: This study seeks for a better understanding of the correlations between major milestones in the womens movement and how that is reflected onto the silver screen. With the rise of sexual assault allegations against prominent figures in Hollywood, and the growth of the #MeToo movement, we in turn are beginning to see an influx of films being released, and older films being rebooted, with an all-female led cast. One of those all-female film reboots is Oceans Eight, a film coming from a male-dominated trilogy and genre. Because of this correlation, the question of whether the narratives within Oceans Eight reinforce gendered stereotypes that have been engraved over time? Is the film just a marketing ploy for Hollywood to gain back a positive reputation with female audiences and profit from the popularized female empowerment topic Are there double standards placed on female leads in Oceans Eight versus their male counterparts in Oceans Eleven? Also, are the women in Oceans Eight being sexually objectified the way women usually are in heist films? A textual analysis was conducted on the narratives, characteristic traits, the portrayals of same sex friendships and costume design from Oceans Eight in comparison to Oceans Eleven. What was found from the analysis was that Oceans Eight broke some stereotypes and eliminated sexual objectification in the characteristic traits and costume design, but still reinforced stereotypes and objectification through the narrative and the portrayals of same sex friendships.

description: The proximity effect of a C-type antiferromagnet (C-AFM) with the spin canting at low temperature is investigated in the hybrid Nd0.35Sr0.65MnO3(NSCO)/YBa2Cu3O7(YBCO) oxide system through magnetic and transport measurements. It is found that the onset of a spin-canted state destroys partially the superconducting order parameter. Interestingly, due to the instability of this spin-canted state, zero-resistivity recovers at the offset of spin canting. Our result demonstrates clearly the high sensitivity of superconducting order parameter to a modulation of internal field.

description: Low-dimensional behavior of large systems of globally coupled oscillators has been intensively investigated since the introduction of the Ott-Antonsen ansatz. In this report, we generalize the Ott-Antonsen ansatz to second-order Kuramoto models in complex networks. With an additional inertia term, we find a low-dimensional behavior similar to the first-order Kuramoto model, derive a self-consistent equation and seek the time-dependent derivation of the order parameter. Numerical simulations are also conducted to verify our analytical results.

description: A difficult task with many particle detectors focusing on interactions below ~100 keV is to perform a calibration in the appropriate energy range that adequately probes all regions of the detector. Because detector response can vary greatly in various locations within the device, a spatially uniform calibration is important. We present a new method for calibration of liquid xenon (LXe) detectors, using the short-lived 83m-Kr. This source has transitions at 9.4 and 32.1 keV, and as a noble gas like Xe, it disperses uniformly in all regions of the detector. Even for low source activities, the existence of the two transitions provides a method of identifying the decays that is free of background. We find that at decreasing energies, the LXe light yield increases, while the amount of electric field quenching is diminished. Additionally, we show that if any long-lived radioactive backgrounds are introduced by this method, they will present less than 67E-6 events/kg/day in the next generation of LXe dark matter direct detection searches

description: Mobility challenges affect millions worldwide, severely limiting independence and access to reliable transportation for individuals with disabilities. Despite advancements in assistive technology, existing vehicle entry systems—such as ramps and hydraulic lifts—continue to fall short due to high costs, mechanical complexity, and difficulties in achieving seamless factory integration. These limitations hinder widespread adoption and risk compromising user safety and independence. 
Our project targets the Volkswagen ID Buzz, an electric vehicle that represents a unique opportunity for incorporating inclusive design solutions directly into the production process. Our work is focused on enhancing vehicle accessibility for mobility-impaired users through innovative engineering that is both practical and compliant with stringent standards such as the Americans with Disabilities Act (ADA). 
We aim to overcome the limitations of traditional ramp and lift systems by developing an integrated entry mechanism that wheelchair users can independently operate. Our solution features a scissor lift mechanism seamlessly integrated into a modified car and door frame with linear actuators to fold the platform into the door, ensuring it remains stowed when not in use and fully extends to the ground when needed, optimizing both functionality and design.
We developed a 50% scale prototype capable of withstanding 300 pounds, meeting ADA load-bearing requirements, and successfully demonstrated a full lift cycle while carrying a person. These results indicate that our design not only meets safety and accessibility standards but also offers a practical alternative for factory-integrated vehicle accessibility solutions.

Landscape Scale: Inter- and Intraspecific Variation in Plant Interactions along a Stress Gradient in the Sheep Range of Nevada
Creators: name: Dowell, Jordan
Publisher: name: University of Nevada, Las Vegas
Year: 2019

description: Impending threats to shrubland ecosystems, posed by climate change, necessitate niche modeling efforts to project vegetation range shifts. However, efforts often remain unguided by individual-scale interspecific plant interactions. The stress gradient hypothesis posits that facilitation should increase in areas of high abiotic stress, only if the individuals are able to ameliorate the surrounding area via functional traits. The Sheep Range of Nevada was used to assess the role of functional traits as predictors of plant association. Larrea tridentata, Coleogyne ramosissima, and Artemisia nova were selected as shrubs with variable life history strategies and ranges in order to identify general patterns between canopy level traits concerning morphology and physiology to intensity of interactions. Over the observed gradient there was a predominance of competition, defined by reduced undershrub abundance in comparison to adjacent spaces. However, data suggest that interaction may not be driven specifically by macroclimate but by microclimate modulating traits, as observed net effects of facilitation or competition were more greatly impacted by composites of traits, as opposed to singular traits. Composite traits that parsed canopy morphology and physiology, defining plants by canopy size, leaf nutritional value, and resource-use efficiency were significant predictors of relative interaction intensity (RII) (Adj. R2 = 0.49--0.7, p < 0.01). ?15N, was the only singular trait positively associated with RII when accounting for other aspects of climate and plant physiology and morphology (Adj. R2 = 0.64, p < 0.001). Contrary to the stress gradient hypothesis, climate what not a significant predictor of RII when accounting for plant morphology and physiology. Over time as the macroclimate continues to fluctuate, above and beyond ameliorative ability, these facilitative interactions may shift to competition. As such, further identification of patterns of association and trait characteristics will be imperative to provide suitable assessments of potential community dynamics shifts.
On the generation of high energy photons detected by the Fermi Satellite from gamma-ray bursts

description: Observations of gamma-ray bursts by the Fermi satellite, capable of detecting photons in a very broad energy band: 8keV to >300GeV, have opened a new window for the study of these enigmatic explosions. It is widely assumed that photons of energy larger than 100 MeV are produced by the same source that generated lower energy photons -- at least whenever the shape of the spectrum is a Band function. We report here a surprising discovery -- the Fermi data for a bright burst, GRB 080916C, unambiguously shows that the high energy photons (>= 100MeV) were generated in the external shock via the synchrotron process, and the lower energy photons had a distinctly different source. The magnetic field in the region where high energy photons were produced (and also the late time afterglow emission region) is found to be consistent with shock compressed magnetic field of the circum-stellar medium. This result sheds light on the important question of the origin of magnetic fields required for gamma-ray burst afterglows. The external shock model for high energy radiation makes a firm prediction that can be tested with existing and future observations.

Of the eight objects with coverage in our HST/WFPC2 narrow-band imaging, two have clear detections and an additional two are barely detected (~2-sigma). The clear detections are within ~0.5 kpc of the centroid of the corresponding rest-UV continuum source, suggesting that the line-emitting gas and young stars in LAEs are spatially coincident. The brightest object exhibits extended emission with a half-light radius of ~1.5 kpc, but a stack of the remaining LAE surface brightness profiles is consistent with the WFPC2 point spread function. This suggests that the Lyman Alpha emission in these objects originates from a compact (

description: Here we generally prove that the axion as a coherently oscillating scalar field acts as a cold dark matter in nearly all cosmologically relevant scales. The proof is made in the linear perturbation order. Compared with our previous proof based on solutions, here we compare the equations in the axion with the ones in the cold dark matter, thus expanding the valid range of the proof. Deviation from purely pressureless medium appears in very small scale where axion reveals a peculiar equation of state. Our analysis is made in the presence of the cosmological constant, and our conclusions are valid in the presence of other fluid and field components.

Effective gravitational equations of motion at the brane are derived in the covariant approach. Dependence of such brane equations on the bulk quantities is discussed. It is shown that the number of the bulk independent brane equations of motion depends strongly on the symmetries assumed for the model and for the background. Examples with two and four derivatives of the fields are presented in more detail.

description: Today’s smallest energy storage devices for in-vivo applications are larger than 3 mm3 and lack the ability to continuously drive the complex functions of smart dust electronic and microrobotic systems. Here, we create a tubular biosupercapacitor occupying a mere volume of 1/1000 mm3 (=1 nanoliter), yet delivering up to 1.6 V in blood. The tubular geometry of this nano-biosupercapacitor provides efficient self-protection against external forces from pulsating blood or muscle contraction. Redox enzymes and living cells, naturally present in blood boost the performance of the device by 40% and help to solve the self-discharging problem persistently encountered by miniaturized supercapacitors. At full capacity, the nano-biosupercapacitors drive a complex integrated sensor system to measure the pH-value in blood. This demonstration opens up opportunities for next generation intravascular implants and microrobotic systems operating in hard-to-reach small spaces deep inside the human body.

Dark matter haloes determine the masses of supermassive black holes

description: The energy and momentum deposited by the radiation from accretion onto the supermassive black holes (BHs) that reside at the centres of virtually all galaxies can halt or even reverse gas inflow, providing a natural mechanism for supermassive BHs to regulate their growth and to couple their properties to those of their host galaxies. However, it remains unclear whether this self-regulation occurs on the scale at which the BH is gravitationally dominant, on that of the stellar bulge, the galaxy, or that of the entire dark matter halo. To answer this question, we use self-consistent simulations of the co-evolution of the BH and galaxy populations that reproduce the observed correlations between the masses of the BHs and the properties of their host galaxies. We first confirm unambiguously that the BHs regulate their growth: the amount of energy that the BHs inject into their surroundings remains unchanged when the fraction of the accreted rest mass energy that is injected, is varied by four orders of magnitude. The BHs simply adjust their masses so as to inject the same amount of energy. We then use simulations with artificially reduced star formation rates to demonstrate explicitly that BH mass is not set by the stellar mass. Instead, we find that it is determined by the mass of the dark matter halo with a secondary dependence on the halo concentration, of the form that would be expected if the halo binding energy were the fundamental property that controls the mass of the BH. We predict that the logarithmic slope of the relation between dark matter halo mass and black hole mass is 1.55+/-0.05 and that the scatter around the mean relation in part reflects the scatter in the halo concentration-mass relation.

Community policing and refugee settlement in Regional Australia: A case study of Tasmania
Creators: name: Campbell, DM
Publisher: name: University Of Tasmania
Year: 2023

description: Although Australian police were not the perpetrators of the profound violation of trust that characterises the refugee experience, they have the potential to be one of the key agencies in settlement to assist in the restoration of trust. This research explores the perspectives of police and refugees concerning police-refugee and refugee-police relations. The research was conducted in Tasmania, Australia, as a regional location settling refugees. The qualitative research involved 160 participants including police and members of seven of the African newly arrived refugee communities. The data was collected from 2006 to 2008, a time that was characterised by periods of negative media attention focusing on African refugees and debate about settlement in regional Australia. The research offers an understanding of both the perspectives of police and the members of newly arrived African communities in regional Australia on factors that can influence interactions between them. The research reveals that an understanding of experiential difference and community dynamics is crucial. The data analysis identified three distinct themes affecting police-refugee relations: the process of transition for refugees, the timing of police interventions and individual/community dynamics, highlighting a need for police awareness of the refugee experience and how this awareness may then influence contact between police and refugees. The study also tackles the issues of reporting and racism from both the perspectives of police and the African refugee communities.The research explores ways to expand community involvement in a range of safety and crime prevention initiatives by increasing the flow of information between refugee communities and police, and improving feelings of safety and security for individual refugees, refugee communities and police. The study identifies principles to create, maintain and sustain positive police-refugee relationships that support the complex dynamics of settlement in regional Australia, with a focus on the vulnerability of refugees during stages of transition. It was found that using a number of targeted community policing strategies to support newly arrived refugee communities during initial settlement contributed to an increase in refugees' understandings of Australian law and that trust, perceived legitimacy in police, and cooperation were increased. The thesis also argues that police-refugee relationships are enhanced by a procedural justice framework and could be positively affected by restorative justice practices. Finally, the findings from this research can be translated into a series of practical applications that could have a positive impact on the effectiveness and efficiency of police work by increasing the capacity for community engagement, improving feelings of safety and encouraging reporting to police.

By means of a regularization we prove that the canard cycles are singular orbits of singular perturbation problems which are limit periodic sets of a sequence of limit cycles. Moreover, we generalize the Poincaré Index for non-smooth vector fields.

description: We report studies of photon-stimulated desorption (PSD), also known as light-induced atomic desorption(LIAD), of sodium atoms from a vacuum cell glass surface used for loading a magneto-optical trap (MOT). Fluorescence detection was used to record the trapped atom number and the desorption rate. We observed a steep wavelength dependence of the desorption process above 2.6 eV photon energy, a result significant for estimations of sodium vapor density in the lunar atmosphere. Our data fit well to a simple model for the loading of the MOT dependent only on the sodium desorption rate and residual gas density. Up to 3.7x10^7 Na atoms were confined under ultra-high vacuum conditions, creating promising loading conditions for a vapor cell based atomic Bose-Einstein condensate of sodium.

description: The implementation of an efficient and sustainable management of the organic fraction of municipal solid wastes (OFMSW) is a topic of intensive discussion in EU countries. Recently, the OFMSW has been investigated as a potential substrate for the production of lactic acid (LA) through fermentation. Nevertheless, none of the reports available in the literature covers all the stages of the conversion process. The present research article is a comprehensive study which includes the upstream, fermentation and downstream for the conversion of OFMSW into LA. Several batches of OFMSW were analysed for the evaluation of sugars released and LA content before the fermentation. Fermentations were performed to study the effect of hydrolysate quality on the LA production using Bacillus coagulans A166. Purification of LA, based on electrodialysis, was carried out after pilot scale fermentation of OFMSW hydrolysates. Results showed that variations in the concentrations of sugars and LA are observed from batch to batch of OFMSW. More specifically, LA can reach high concentrations even before the substrates are hydrolysed, limiting the potential applications of the final product due to low enantiomeric purities. In general, fermentations of the hydrolysate were efficient, with conversion yields of 0.65 g g−1 without the addition of extra nutrients. Downstream is still a challenging stage of the process. A LA recovery of 55% was obtained, with the most significant losses observed during the micro- and nanofiltrations. Overall, a conversion of 10% from OFMSW substrate (dry basis) to LA was achieved.

description: We use a sample of close galaxy pairs selected from the Sloan Digital Sky Survey Data Release 4 (SDSS DR4) to investigate in what environments galaxy mergers occur and how the results of these mergers depend on differences in local galaxy density. The galaxies are quantified morphologically using two-dimensional bulge-plus-disk decompositions and compared to a control sample matched in stellar mass, redshift and local projected density. Lower density environments have fractionally more galaxy pairs with small projected separations (r_p) and relative velocities (Delta v), but even high density environments contain significant populations of pairs with parameters that should be conducive to interactions. Metrics of asymmetry and colour are used to identify merger activity and triggered star formation. The location of star formation is inferred by distinguishing bulge and disk colours and calculating bulge fractions from the SDSS images. Galaxies in the lowest density environments show the largest changes in star formation rate, asymmetry and bulge-total fractions at small separations, accompanied by bluer bulge colours. At the highest local densities, the only galaxy property to show an enhancement in the closest pairs is asymmetry. We interpret these results as evidence that whilst interactions (leading to tidal distortions) occur at all densities, triggered star formation is seen only in low-to-intermediate density environments. We suggest that this is likely due to the typically higher gas fractions of galaxies in low density environments. Finally, by cross-correlating our sample of galaxy pairs with a cluster catalogue, we investigate the dependence of interactions on clustercentric distance. It is found that for close pairs the fraction of asymmetric galaxies is highest in the cluster centres.

description: Time delay estimation arises in many applications in which a multipath medium has to be identified from pulses transmitted through the channel. Various approaches have been proposed in the literature to identify time delays introduced by multipath environments. However, these methods either operate on the analog received signal, or require high sampling rates in order to achieve reasonable time resolution. In this paper, our goal is to develop a unified approach to time delay estimation from low rate samples of the output of a multipath channel. Our methods result in perfect recovery of the multipath delays from samples of the channel output at the lowest possible rate, even in the presence of overlapping transmitted pulses. This rate depends only on the number of multipath components and the transmission rate, but not on the bandwidth of the probing signal. In addition, our development allows for a variety of different sampling methods. By properly manipulating the low-rate samples, we show that the time delays can be recovered using the well-known ESPRIT algorithm. Combining results from sampling theory with those obtained in the context of direction of arrival estimation methods, we develop necessary and sufficient conditions on the transmitted pulse and the sampling functions in order to ensure perfect recovery of the channel parameters at the minimal possible rate. Our results can be viewed in a broader context, as a sampling theorem for analog signals defined over an infinite union of subspaces.

description: We quantify the amount of non-locality contained in n noisy versions of so-called Popescu-Rohrlich boxes (PRBs), i.e., bipartite systems violating the CHSH Bell inequality maximally. Following the approach by Elitzur, Popescu, and Rohrlich, we measure the amount of non-locality of a system by representing it as a convex combination of a local behaviour, with maximal possible weight, and a non-signalling system. We show that the local part of n systems, each of which approximates a PRB with probability $1-ε$, is of order $Θ(ε^{\lceil n/2\rceil})$ in the isotropic, and equal to $(3ε)^n$ in the maximally biased case.

Evaluation and Professional Development Practices in Tasmanian High Schools
Creators: name: Kertesz, JL
Publisher: name: University Of Tasmania

description: This study reports on teacher evaluation and professional development practices in Tasmanian high schools. It was conducted within a context of increasing regulation of teachers through legislated registration and directed standards. The thesis in this study is that there is insufficient linkage between teacher evaluation and professional development. The study investigates whether Tasmanian high schools monitor teaching, and verify whether teacher learning leads to explicit pedagogical outcomes. By considering factors such as organisational theory, teacher competence, evaluation objectives and approaches, and the impact of change, a list of ideal objectives and characteristics for the evaluation of teachers is established. By examining organisational support of new pedagogies, the application of stage theory to determine individual needs, and validation of training to ensure that learning has been applied, a similar list of ideal objectives and characteristics is obtained for professional development. A sample of 193 high school teachers was surveyed to determine the extent of teacher evaluation by supervisors, and independent reflective pedagogical practices. It also examined professional development participation, effectiveness, and satisfaction. Teacher perceptions of their ability to affect their performance management were analysed. The state wide survey is complemented by case studies of four high schools to reveal extant evaluation and professional development practices and attitudes. Surveys of documentation and teacher attitudes are supported by student focus group discussions to yield an insight into classroom realities. The state wide survey revealed that formal evaluation and classroom observation were uncommon, and that one third of the sample rarely engaged in scheduled discussions about pedagogy. Teacher attitudes to professional development were positive, but one in four teachers were dissatisfied with its management and outcomes. Surveyed teachers felt collectively strong and individually weak to influence extant evaluation and professional development practices. Only one case study school used evaluation as other than an intermittent selection tool, but half of the teachers in this school felt no ownership of, and lacked trust, in the process. Professional development choices in all case study schools were often based on enjoyment, and outcomes for teaching and learning were rarely validated. The research suggests that the establishment of evaluation or external implementation of teacher standards may be undermined by current professional development practices that are neither based on classroom needs, nor validated to ensure pedagogical outcomes. Collective independent utilisation of established standards methodologies by teachers themselves to establish reflective pedagogy could be the most effective way of enhancing teaching quality.
