description: The self-similar structure of the attracting subshift of a primitive substitution is carried over to the limit set of the repelling tree in the boundary of Outer Space of the corresponding irreducible outer automorphism of a free group. Thus, this repelling tree is self-similar (in the sense of graph directed constructions). Its Hausdorff dimension is computed. This reveals the fractal nature of the attracting tree in the boundary of Outer Space of an irreducible outer automorphism of a free group.

description: While the past few years have seen a growth of research exploring changes in second language (L2) motivation over different timescales, the construct of engagement and its relationship with motivation in the L2 classroom have remained relatively underresearched in the field of Second Language Acquisition (SLA) from a dynamic perspective to date. The present study seeks to examine variability in L2 motivation and four subsets of student engagement (i.e. behavioural, cognitive, emotional and social) over the course of four single lessons and throughout the academic year, and to explore the interconnections between the two constructs. The research comprises a set of data drawn from five classes of French and Spanish at different proficiency levels at a British university. Inspired by MacIntyre and Legatto’s (2011) ‘Idiodynamic Method’ and by Waninge, Dörnyei, and de Bot’s (2014) ‘Motometer’, the research method developed for the present study allowed (a) to capture micro- and macro-fluctuations in motivation and engagement, and (b) to explore the complex interplay of variables that mediate this relationship. The participating students rated their motivation every 2.5 minutes based on a replay of the lesson on a tailor-made chart. During follow-up cued interviews they were asked to provide a rationale for their changes in motivation and engagement during the lesson. Classroom observations were also conducted for triangulation purposes. Findings suggest that both motivation and all four subsets of engagement were subject to periods of change and stability over time; their changes emerged from the mutual interactions between the learner and the classroom environment. Furthermore, the relationship between the two constructs appeared as dynamic and non-linear. This was mediated by the complex interplay of intrapersonal, behavioural and contextual variables.
Treatment of sanitary landfill leachate with peat
Creators: name: Lidkea, Thomas Roy
Publisher: name: University of British Columbia
Year: 2010

description: Leachate is generated by the action of water on the solid wastes deposited in sanitary landfills or dumps. In this research, peat was investigated as a means of removing metal ions from leachate. The leachate used in the investigation was obtained from a project at the University of British Columbia in which leachate is generated under controlled conditions. Two different types of locally available peat were used in initial batch tests. These were a fibrous peat derived mainly from sphagnum moss and in a middle stage of humification, and a well humified sample of woody peat from the surface. These samples were used to treat distilled water solutions of Fe, Cr, Zn, AI, Cd, and Pb, The fibrous peat was found to be superior and was used in subsequent tests. In the batch tests performed on distilled water solutions of the above metals, it was found that the fibrous peat adsorbed between 12 and 38 mg of metal per gm of peat. In the batch treatment of leachate, the fibrous peat was found to have a capacity of 55 mg/gm. A test conducted to investigate the dependence of adsorption on pH showed that adsorbance was best in the range between pH 3.0 and 4.0. Column tests were performed on distilled water solutions of Cr in order to optimize the column's design. Based on these tests, 60 gm of wet fibrous peat were packed in a column 12 inches high and 0.75 inches in diameter. A flow rate of 0.100 gpm/ft² was used in treating two different samples of leachate. In treating the first leachate, which had a high strength (total metal concentration was 5,360 mg/1) and a pH of 4.84, it was found that the treatment capacity of the peat was about 48 mg/gm. At treatment efficiencies of 90 per cent and 75 per cent, peat capacities were 31.4 and 43.3 mg/gm, respectively. The test of a low strength leachate (total metal concentration was 1,830 mg/1) of pH 5.35 was not valid for assessing the performance of the column since many of the metals were present as solids which were simply filtered out in the column. The usefulness of peat in treating leachate depends on the type and concentration of the leachate. In order to be effective, large amounts of peat may have to be used. For example, to remove 90 per cent of metal ions from 1,000 gal. of the high strength leachate would require roughly 0.77 tons (dry) of peat.
The organisational and social environment of the simulation laboratory, a mediator of vertical and horizontal abuse (VHA) among second-year nursing students : a critical ethnography
Creators: name: Lambert, KE
Publisher: name: University Of Tasmania
Year: 2023

description: Vertical and horizontal abuse (VHA) has been reported in the nursing literature for more than 30 years. Previous research has focused specifically on VHA among nurses employed in the health sector, with some studies examining nursing students' exposure to VHA during clinical training. Little attention has been paid to simulated environments used in the education of student nurses as a potential arena for VHA. This critical ethnographic study sought to address this knowledge deficit by investigating whether the organisational and social environments of a simulated hospital laboratory may enable episodes of VHA. Carspecken's critical ethnography informed the conduct of this research endeavour. Ethical clearance was obtained from the university's Human Research Ethics Committee. In all, 43 participants consented to participate in the study. Monological and dialogical data were collected over 24 weeks, in two sessions. Data collection tools included observations, field notes and artefacts such as codes and policies. Semi-structured interviews were conducted with the key informants. The data were analysed using Carspecken's pragmatic horizon analysis and the findings were explained using Pierre Bourdieu's social practice theory. The key finding was that episodes of VHA were evident among second-year nursing students and academics engaged in learning and teaching in a simulated hospital environment. This study showed that the organisational and social spaces of learning and teaching have been influenced by curriculum design. More significantly, however, by the modern managerial approaches to university and healthcare sectors. In this context, the pressures from outside the university, as well as the challenge for capital within the university, have begun to fracture various fields of practice and in particular, the field of the simulation laboratory. This study contributes to a body of evidenced-based work that argues that education curricula embed values and act as a mechanism to reinforce dominant practices.

description: We examine models for the magneto-conductivity correction in 2DEGs with both Rashba and Dresselhaus spin-orbit coupling (SOC) for their applicability to experimental data fitting. In particular, we compare the Landau-quantized Cooperon approach, which is mostly only numerically treatable, and the quasi-classical approximation that was recently employed to obtain an explicit solution for arbitrary Rashba and Dresselhaus SOC [PRL 112, 156601 (2019)]. It is found that the quasi-classical approximation yields significantly different results even to lowest order in the magnetic field and appears unsuitable for reliable parameter fitting. The discrepancy emerges when a sum over Landau levels is replaced by an integral over wave vectors. Substantial improvement is achieved by supplementing the quasi-classical model with the first two corrections given by the Euler-MacLaurin formula. Corresponding modifications are, however, only feasible in special SOC parameter configurations where the mixing of Landau bands is negligible and a closed-form solution that accounts for Landau quantization is also available. Such a scenario appears in a parameter regime where a persistent spin helix emerges and a transition between weak anti- and weak localization takes place. Combining recent findings, we derive a generalized closed-form expression for the magneto-conductivity correction applicable to generic 2DEGs that are grown along a crystal direction with at least two growth-direction Miller indices equal in modulus. The result is a function of spin lifetimes of the long-lived spin textures and is valid close to the persistent-spin-helix regime. The accuracy of the derived formula is validated by comparing with results from numerical diagonalization of the multiband Cooperon as well as a recently established Monte-Carlo-based real-space simulation in exemplary (001)-, (113)-, and (110)-2DEGs.

description: Defect prevention is the most vital but habitually neglected facet of software quality assurance in any project. If functional at all stages of software development, it can condense the time, overheads and wherewithal entailed to engineer a high quality product. The key challenge of an IT industry is to engineer a software product with minimum post deployment defects. This effort is an analysis based on data obtained for five selected projects from leading software companies of varying software production competence. The main aim of this paper is to provide information on various methods and practices supporting defect detection and prevention leading to thriving software generation. The defect prevention technique unearths 99% of defects. Inspection is found to be an essential technique in generating ideal software generation in factories through enhanced methodologies of abetted and unaided inspection schedules. On an average 13 % to 15% of inspection and 25% - 30% of testing out of whole project effort time is required for 99% - 99.75% of defect elimination. A comparison of the end results for the five selected projects between the companies is also brought about throwing light on the possibility of a particular company to position itself with an appropriate complementary ratio of inspection testing.

Density of states of the Hubbard model supplemented with the quantizing magnetic field

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: Using the strong coupling diagram technique, we calculate the zero-temperature density of states $ρ$ of electrons on a square lattice immersed in a perpendicular uniform magnetic field. The electrons are described by Hubbard Hamiltonian. For moderate doping, Landau subbands are observed for small Hubbard repulsions $U$ only. For larger $U$, the subbands are blurred. Instead, small peaks varying with the field induction $B$ arise by opening the Mott gap in its vicinity. The related variation of $ρ$ with $1/B$ may be connected with the low-frequency quantum oscillations in lightly doped cuprates. For all considered repulsions, $ρ$ has gaps near transfer frequencies of the Hubbard atom, $-μ$ and $U-μ$, with $μ$ the chemical potential. In the heavily underdoped case $μ<0$, Landau subbands are grouped into the lower and upper Hubbard subbands for moderate and large repulsions. The intensity of the upper Hubbard subband decreases with approaching the Fermi level to the lower edge of the spectrum and finally vanishes.

title: Nesting and Habitat Parameters for Selected Raptors in the Desert of Northwestern Utah
Creators: name: Peterson, David L.
Publisher: name: Utah State University
Year: 1988

description: This study examined the effects of habitat parameters, disturbances and predation on the reproductive success of golden eagles (Aguila chrysaetos), ferruginous hawks (Buteo regalis), red-tailed hawks (Buteo jamaicensis) and prairie falcons (Falco mexicanus) in the desert area southwest of the Great Salt Lake in northwestern Utah. The prairie falcon was the only species examined that had a normal reproductive output during the study years of 1984-1986. The prairie falcon was better able to utilize the avian prey species which were very difficult for the larger and slower raptor species to capture. During the reproductive period prairie falcons used Townsend ground squirrel (Sperrnophilus townsendii) heavily. The golden eagles, ferruginous, and red-tailed hawks were not able to obtain sufficient numbers of their primary prey species, the cottontail rabbit (Sylvilagus nuttallii) and black-tailed jackrabbit (Lepus californicus), to allow for a normal reproductive output. These prey species were at the low point of their cyclic population pattern. Disturbance to raptors was not an important factor on this remote study area. Predation, primarily terrestrial mammals, did have a negative effect on reproductive success; however, it was not a major consideration due to lack of predator access on most of the cliff nesting sites of the golden eagle, red-tailed hawk, and prairie falcon. Predation appeared to have a greater impact on the ferruginous hawk nesting success as their nest sites were normally accessable to mammalian predators. Raptor nest site exposure was unimportant to nesting raptors. The nest exposure was very similar to the exposure ratio of the available cliff sites.
title: Control and Evaluation of Big Game Browsing Damage to Commercial Fruit Orchards
Creators: name: Stone, William E.
Publisher: name: Utah State University
Year: 1988

description: Diversionary feeding, artificial feeding designed to divert animals away from areas where they might cause property damage, was tested for efficacy in reducing fruit orchard browsing by big game animals during two consecutive winters in Utah. Strategically placed attractive feedstuffs lured deer to feed stations and reduced fruit-bud browsing (1st year, P< 0.07; 2nd year, P < 0.01). Blossom and apple numbers were greater (P < O. 05) on trees in the feed (treatment) orchard than in the no feed (control) orchard in each year. However, higher (P < 0.05) apple production on trees where browsing was excluded in the treatment orchards compared to the control orchards indicated that intercept feeding did not increase crop production. Tree periodicity and other factors affecting apple production masked the effect of diversionary feeding on crop yield. Two independent browsing damage assessment methods, a paired-tree technique and a harvest-inflation technique, predicted that the ratio of apples lost per browsed bud was 0.158 and 0.082, respectively. However, the values of the ratio varied widely with each method of estimation. Browsing damage differed (P < o. 001) according to branch position (below 1 m and distal, above 1 m and distal, and above 1 m and proximal to the tree trunk). A less intensive count of buds and browsed buds reliably predicted average browsing damage in the orchard (determined by counting all browsing zone buds on 5% of the orchard trees), when these branch classes were used. An economic analysis of this feeding program indicated that, at current prices, the value of the increased crop in the study orchards did warrant the cost of feeding associated with them (benefit/cost= 9.20 and 32.89). Deer-proof fencing, although expensive to install, is a more cost-efficient (benefit/cost= 129.28 and 121.11) method of preventing browsing damage in the orchards I studied.

title: The Effects of Forest Harvesting on Small Mammals in Western Newfoundland and its Significance to Marten
Creators: name: Tucker, Brian
Publisher: name: Utah State University
Year: 1988

description: The depauperate fauna of Newfoundland provides a limited prey base for marten. Only two small mammal prey species, Microtus pennsylvanicus and Sorex cinereus, were found in any abundance in the old-growth forests of the study area. Of these two, Microtus displayed population fluctuations typical of most microtines. Analysis of marten scats indicated that Microtus is a very important prey item to the marten with other food. items being of lesser importance particularly when Microtus are abundant. Trapping in various habitats indicated that Sorex densities were three to five times higher in logged areas compared to uncut areas. Unfortunately, the effects of logging on Microtus could not be determined directly from this study. Microtus numbers declined drastically in the spring of 1987, apparently independently of logging operations. Microtus numbers dropped from a density of 25.0 per hectare in the spring of 1986 to virtually zero in the spring of 1987. This reduction may be linked to an outbreak of viral encephalitus in the marten population in the fall of 1986. Marten (Martes arnericana) prefer mature coniferous and mixed forests and utilize regenerating cutovers minimally. The reasons for this are unclear, although prey abundance and availability may be involved. In this study, Sorex were more abundance in regenerating cutovers and the literature suggests that Microtus are also more abundant in these areas. This would seem to suggest that prey abundance above certain threshold densities is not critical to marten habitat selection. However, prey availability may play a more important role. Although prey species may be more abundance in logged areas, prey availability may be reduced.

description: Using archival near-IR photometry, we identify 51 of the K-band brightest red supergiants (RSGs) in NGC 6822 and compare their physical properties with stellar evolutionary model predictions. We first use Gaia parallax and proper motion values to filter out foreground Galactic red dwarfs before constructing a J - K vs. K color-magnitude diagram to eliminate lower-mass asymptotic giant branch star contaminants in NGC 6822. We then cross-match our results to previously spectroscopically confirmed RSGs and other NGC 6822 content studies and discuss our overall completeness, concluding that radial velocity alone is an insufficient method of determining membership in NGC 6822. After transforming the J and K magnitudes to effective temperatures and luminosities, we compare these physical properties with predictions from both the Geneva single-star and Binary Population and Spectral Synthesis (BPASS) single and binary star evolution tracks. We find that our derived temperatures and luminosities match the evolutionary model predictions well, however the BPASS model that includes the effects of binary evolution provides the best overall fit. This revealed the presence of a group of cool RSGs in NGC 6822, suggesting a history of binary interaction. We hope this work will lead to further comparative RSG studies in other Local Group galaxies, opportunities for direct spectroscopic follow-up, and a better understanding of evolutionary model predictions.

description: Motivated by recent measurements of the top quark forward-backward asymmetry at the Tevatron, we study how t-channel new physics can contribute to a large value. We concentrate on a theory with an abelian gauge boson possessing flavor changing couplings between up and top quarks, but satisfies flavor physics constraints. Collider constraints are strong, but can be consistent with the aid of small flavor diagonal couplings. We find that M_Z' ~ 160 GeV can yield a total lab-frame asymmetry of ~18% without being in conflict with other observables. There are implications for future collider searches, including exotic top quark decays, like-sign top quark production, and detailed measurements of the top production cross section. An alternate model with a gauged non-Abelian flavor symmetry would have similar phenomenology, but lacks the like-sign top signal.

Regional cooperation over Gulf of Guinea resources
Creators: name: Adusu, Sylvia
Publisher: name: Lancaster University
Year: 2020

description: This thesis explores how states bordering the Gulf of Guinea can cooperate in the exploitation, conservation and management of the region’s marine resources. Within the framework of international law generally, and the United Nations law of the Sea Convention (UNCLOS) in particular, the thesis demonstrates the legal basis for cooperation in four key areas: - maritime boundary delimitation, exploitation of non- living marine resources of the seabed, protection of the marine environment from pollution arising out of such exploitation and the conservation and management of the living marine resources. The thesis applies a positivist analysis of international law, following a law-in-context approach. The key findings relate to challenges to the states’ duties to cooperate in the areas of delimiting their maritime boundaries due to the many maritime boundary disputes in the area and the lack of cooperative regimes for joint development of non-living resources. Another challenge identified is inadequate regional and national frameworks for the protection of the marine environment from pollution arising out of exploitation as well as for dealing with issues of liability from pollution incidents. Cooperation in the conservation and management of marine living resources is also insufficient. The thesis recommends regional and sub-regional cooperation by means of appropriate regional, sub-regional and national mechanisms.
Treatability of leachate from a sanitary landfill by anaerobic digestion
Creators: name: Poorman, Basil Lloyd
Publisher: name: University of British Columbia
Year: 2010

description: Pollution control authorities are becoming more and more concerned about the effects of highly polluted leachate from solid waste landfills on receiving waters. Control or treatment of such leachate is thus becoming very important. This study was established to investigate the possibility of reducing the amounts of oxygen demanding material in the leachate by anaerobic digestion without any prior removal of heavy metals which were contained in it. It also included a study of the effects of varied detention time and the changing characteristics of the leachate. BOD₅, removals ranging from 80 to 96 percent were achieved for detention times ranging from 5 to 20 days and influent BOD₅'s ranging from 11,000 to 16,000 mg/1. C.O.D. removals ranged from 65 to 79 percent for influent values ranging from 23,000 to 33,000 mg/1. A variety of metals including aluminum, cadmium, chromium, copper, lead, mercury, nickel and zinc were present in the leachate. Their concentrations covered a broad range with zinc being the highest at 65 mg/1. The anaerobic digestion process was not adversely effected by these metals. Some of these metals, notably aluminum, cadmium, mercury, nickel and zinc were essentially completely associated with the sludge, while the others were associated to a lesser extent. Gas production ranged from 11.9 to 15.0 cubic feet per pound of BOD₅ destroyed, and methane production ranged from 5.8 to 6.8 cubic feet per pound of C.O.D. destroyed. From the results obtained the indications are that leachate treatability by anaerobic digestion holds good prospects. Since at 20 days detention time 96 percent removal was achieved it is likely that detention times beyond 20 days would result in a greater percent removal.

description: First we present and theoretically analyze the phenomenological physical picture behind Vibration-Induced Conductivity Fluctuations. We identify the relevant tensors characterizing the electromechanical response against the vibrations for both longitudinal and transversal responses. We analyze the conductivity response with acceleration type vibrations and a new scheme, measurements with more advantageous compression type vibrations that are first introduced here. Compression vibrations provide sideband spectral lines shifted by the frequency of the vibration instead of its second harmonics; moreover the application of this method is less problematic with loose electrodes. Concerning geometry and electrodes, the large measurement errors in earlier experiment indicated electrode effects which justify using four-electrode type measurements. We propose and analyze new arrangements for the longitudinal and transversal measurements with both compression vibration and acceleration vibration for laboratory and field conditions.

description: We study the use of NLO and NNLO formulae from SU(2) chiral perturbation theory to fit results from the 2+1 flavor DWF QCD ensembles that have been generated by the RBC and UKQCD collaborations. These ensembles are at two different lattice spacings, contain multiple dynamical light quark masses, and include a variety of partially quenched valence quark masses. Both NLO and complete NNLO fits well represent our data, which has m_pi in the range 220 to 420 MeV. With our data, the NNLO fits have NLO and NNLO contributions of similar size, making the series not convergent and the extrapolation to physical light quark masses imprecise. Thus, we use NLO fit results for our predictions of f_pi, f_K and the light quark masses.

Development and simulation of a traction control system using individual motor direct torque control techniques for a formula SAE electric racing vehicle
Creators: name: Ji, P
Publisher: name: University Of Tasmania
Year: 2023

description: Independent-drive electric vehicles represent an advanced approach to vehicle dynamic control. The main feature of these systems is that they use traction motors that are independently connected to each wheel. This results in a shorter driveline, higher transmission efficiency, more compact packaging, and better utilisation of space. Combined with the torque information produced by electric traction motors, an independent-drive electric vehicle system is capable of performing traction control, antilock braking control and electronic power steering. Traction control is also an effective strategy to control longitudinal vehicle dynamics that functions by preventing the wheels from slipping while driving. It has potential for optimising vehicle dynamics during frequent acceleration and takeoff. Since the late 1990s, there have been several studies regarding traction control for fully electric motor drive vehicles. These studies have investigated traction control systems based on fuzzy methods, rule-based control, slidingmode control, Proportional‚Äö-Integral‚Äö-Derivative control and modification, optimal linearisation control and model-based control. A further distinction can be made between torque-based control, slip-based control and systems that combine both. Nevertheless, most of the existing studies of torque-based traction control have been investigated only in simulation. Further, since 2012, only four studies have focused on designing an electric motor controller with an embedded traction control algorithm. The aim of this project is to understand and develop a traction control system that can be used for the future University of Tasmania Formula SAE electric racing vehicle. Following the guidelines of the Formula SAE rules, the vehicle will be an 80 kW, 600 V peak, rear-wheel drive, open-wheel formula race vehicle.
XMM-Newton observations of Seyfert galaxies from the Palomar spectroscopic survey: the X-ray absorption distribution

description: We present XMM-Newton spectral analysis of all 38 Seyfert galaxies from the Palomar spectroscopic sample of galaxies. These are found at distances of up to 67 Mpc and cover the absorbed 2-10 keV luminosity range ~10^38-10^43 ergs/s. Our aim is to determine the distribution of the X-ray absorption in the local Universe. Three of these are Compton-thick with column densities just above 10^24 cm^-2 and high equivalent width FeKa lines (>700 eV). Five more sources have low values of the X-ray to [OIII] flux ratio suggesting that they could be associated with obscured nuclei. Their individual spectra show neither high absorbing columns nor flat spectral indices. However, their stacked spectrum reveals an absorbing column density of N_H~10^23 cm^-2. Therefore the fraction of absorbed sources (>10^22 cm^-2 could be as high as 55+/-12%. A number of Seyfert-2 appear to host unabsorbed nuclei. These are associated with low-luminosity sources Lx < 3x10^41 ergs/s. Their stacked spectrum again shows no absorption while inspection of the \chandra images, where available, shows that contamination from nearby sources does not affect the {\it XMM-Newton} spectra in most cases. Nevertheless, such low luminosity sources are not contributing significantly to the X-ray background flux. When we consider only the brighter, $>10^{41}$ \lunits, 21 sources, we find that the fraction of absorbed nuclei rises to $75\pm19 $ % while that of Compton-thick sources to 15-20%. The fraction of Compton-thick AGN is lower than that predicted by the X-ray background synthesis model in the same luminosity and redshift range.}

Creators: name: Kay, Charles Edward
Publisher: name: Utah State University
Year: 1990

description: Prior to 1968, the National Park Service contended that an unnaturally large population of elk had severely damaged Yellowstone Park's northern winter range, including aspen and willow communities. However, under "natural regulation" management adopted in the earl y 1970s the agency now believes that vegetation changes in the park are due to normal plant succession, climatic change, or fire suppression, not ungulates. The agency also believes that large numbers of elk (12, 000 - 15, 000) have wintered on the park's northern range for the last several thousand years. This study tested several of the major assumptions or predictions of the Park Service's "natural regulation" paradigm by collecting vegetational data, reviewing historical source materials, and analyzing archaeological reports. The available evidence suggests that observed changes in Yellowstone's tall willow and aspen communities are due primarily to ungulate browsing, not other factors. The future of sexually reproducing willow and aspen communities on the park's northern range appears to be in jeopardy. Under current management, their extinction is only a matter of time. Moreover, entire plant and animal communities have been affected, not just aspen and willows. Historical accounts and archaeological data indicate that few elk inhabited Yellowstone prior to creation of that national park in 1872. These results do not support the "natural regulation" paradigm. Prior to European influence, predation by Native Americans and carnivores limited elk, as well as other ungulate numbers throughout the Greater Yellowstone area.
Foster Wallace's The Empty plenum‚ÄövÑvp revisited : exploring the intersection of philosophic and literary inquiry
Creators: name: Tempone Wiltshire, JV

description: In a political moment characterised by post-truth ideologically generated misinformation and algorithmically propagated discourses, questions of fact, of inquiry, of perspective are paramount. This work examines what it means to write literature or to do philosophy while encountering a world of diffuse truths. It asks how can we retain clarity without erasing the fact that perspectival knowledge is always already embedded, piecemeal, contextual? To answer this question, I turn to a more foundational one, that has plagued philosophy since Plato proclaimed, there is an old quarrel between philosophy and poetry‚ÄövÑvp (Republic, 607b5‚Äö-6). My thesis picks up on a central aspect of the quarrel, the claim that art doesn't lead to truth. I ask: what is the nature of literary inquiry and how can literature distinguish itself as an autonomous form of intellectual inquiry, if it can at all? Beginning with David Foster Wallace's The Empty Plenum‚ÄövÑvp, I argue for a novel 'perspectival' or 'mystical' interpretation of Wittgenstein's Tractatus Logio-Philosophicus. Contrary to dominant literary scholarship, I claim that it is Wittgenstein's Saying‚Äö-Showing distinction that offers us a guide for conceiving of the true value of literary inquiry, and thereby provides us with a robust response to Plato. The 'ancient quarrel' can thus be addressed resolutely. What does literature offer? Literature is free to communicate where philosophy is unable‚ÄövÑvÆto show what philosophy cannot say. Using the examples of Davidson, Heidegger, Wallace, Wittgenstein, Borges and Lerner I flesh out the notion of showing in literature, and how it functions to induce a perspectival shift in order that the reader may see the world 'aright', whatever 'aright' may be. This dissertation may be best conceived as a contribution to the project of questioning inherent power-dynamics and ideological bias that inform the disciplinary separation of literature and philosophy.

title: Water Entry Impact Dynamics of Diving Birds
Creators: name: Sharker, Saberul Islam
Publisher: name: Utah State University
Year: 2017

description: Some seabirds (such as Northern Gannets and Brown Boobies) can dive from heights as high as 30 m reaching speeds of up to 24 m/s as they impact the water surface. It is perceived that physical geometry, particularly of the beak, allows them to endure relatively high impact forces that could otherwise kill non-diving birds. Acceleration data from simplified models of diving birds agree with simulated data for one species (Northern Gannet), however, no reliable experimental data with real bird geometries exist for comparison purposes. This study utilizes eleven 3D printed diving birds (five plunge-diving, five surface-diving and one dipper) with embedded accelerometers to measure water-entry impact accelerations for impact velocities ranging between 4.4 - 23.2 m/s. Impact forces for all bird types are found to be comparable under similar impact conditions and well within the safe zone characterized by neck strength as found in recent studies. However, the time each bird requires to reach maximum impact acceleration and its effect represented here by the derivative of acceleration (i.e., jerk), is different based on its beak and head shape. We show that surface diving birds cannot dive at high speeds as the non-dimensional jerk experienced exceeds a safe limit estimated from human impact analysis, whereas those by plunge divers do not.

Data-aided Sensing where Communication and Sensing Meet: An Introduction

description: Since there are a number of Internet-of-Things (IoT) applications that need to collect data sets from a large number of sensors or devices in real-time, sensing and communication need to be integrated for efficient uploading from devices. In this paper, we introduce the notion of data-aided sensing (DAS) where a base station (BS) utilizes a subset of data that is already uploaded and available to select the next device for efficient data collection or sensing. Thus, using DAS, certain tasks in IoT applications, including federated learning, can be completed by uploading from a small number of selected devices. Two different types of DAS are considered: one is centralized DAS and the other is distributed DAS. In centralized DAS, the BS decides the uploading order, while each device can decide when to upload its own local data set among multiple uploading rounds in distributed DAS. In distributed DAS, random access is employed where the access probability of each device is decided according to its local measurement for efficient uploading.

description: Multi-particle correlation techniques are frequently used to study jet shapes and yields in hadronic and nuclear collisions. To date, a standard assumption applied in such analyses is that the observed correlations arise from either jets and associated hard scattering phenomena, or from a background component due to combinatorial pairs connected only through whole even correlations. Within this assumption of two essentially independent sources, a fundamental problem centers around determining the relative contributions of each component. We discuss the methods commonly used to establish the background yield in jet correlation analyses, with a full explanation of the absolute background normalization technique which establishes the background yield without assumptions about the shape of jet correlations. This is especially important in relativistic heavy ion collisions where the jet shapes are significantly distorted from the well separated back-to-back di-jets observed in proton-proton collisions.
