Modeling distal pointing on large screens : the influence of target depth
Creators: name: Janzen, Izabelle
Publisher: name: University of British Columbia
Year: 2016

description: Pointing is a fundamental task within many interactions in current computer applications. It is incorporated into everything from selecting buttons to dragging files or positioning objects in a virtual environment. Thus, understanding, modeling and predicting pointing performance is crucial to the design and evaluation of many computer interfaces. Fitts’s Law (1954) is the basis for modeling human pointing performance in the international standard on pointing device evaluation (ISO 9241-400:2007). However, while it is extremely robust for many standard desktop applications, previous work by Shoemaker et al. (2012) has suggested that Fitts’s Law may not be robust enough to accurately model pointing at more extreme levels of gain and has proposed alternatives to Fitts’s Law based on earlier work by Welford (1968). This thesis extends preliminary research by Rajendran (2012) that further examined these alternatives to Fitts’s Law for distal pointing. Distal pointing is common in virtual and augmented reality interfaces. We first re¨analyze results reported by Rajendran using a variety of Welford-style models to explore the relationship between target depth and a parameter k that was first suggested by Kopper et al. (2010) but is inherent inWelford’s model. We then present a new experiment that removes the confound of system latency from Rajendran’s approach. Our analyses provide evidence that k varies monotonically (possibly linearly) with target depth, which further supports the claim by Shoemaker et al. that Welford-style two-part models are preferable to Fitts-style one-part models in some situations. Our analyses also challenge Kopper et al.’s suggestion that angular measures of task difficulty are superior to linear measures for pointing models. We close with a discussion of how our findings about the variation of k with target depth might be used in calibration procedures for virtual environments.

description: Magnetism plays a key role in modern technology as essential building block of many devices used in daily life. Rich future prospects connected to spintronics, next generation storage devices or superconductivity make it a highly dynamical field of research. Despite those ongoing efforts, the many-body dynamics of complex magnetism is far from being well understood on a fundamental level. Especially the study of geometrically frustrated configurations is challenging both theoretically and experimentally. Here we present the first realization of a large scale quantum simulator for magnetism including frustration. We use the motional degrees of freedom of atoms to comprehensively simulate a magnetic system in a triangular lattice. Via a specific modulation of the optical lattice, we can tune the couplings in different directions independently, even from ferromagnetic to antiferromagnetic. A major advantage of our approach is that standard Bose-Einstein-condensate temperatures are sufficient to observe magnetic phenomena like Néel order and spin frustration. We are able to study a very rich phase diagram and even to observe spontaneous symmetry breaking caused by frustration. In addition, the quantum states realized in our spin simulator are yet unobserved superfluid phases with non-trivial long-range order and staggered circulating plaquette currents, which break time reversal symmetry. These findings open the route towards highly debated phases like spin-liquids and the study of the dynamics of quantum phase transitions.

Evaluating the comprehensive fatigue assessment battery for adults with spinal cord injury
Creators: name: Diab, Kyle Jean
Publisher: name: University of British Columbia
Year: 2016

description: Background: Individuals living with spinal cord injuries (SCI) are faced with the increased likelihood of secondary health complications, affecting their physical and psychological functioning. Fatigue is among the most common of these problems and has been shown to profoundly affect the lives of people living with SCI. To develop effective fatigue management programs, clinicians first must be able to identify potential causes of fatigue. However, to our knowledge, there is currently no validated, comprehensive assessment battery of this kind. Purpose: The purpose of this study is to test the convergent validity, and internal consistency of a novel Comprehensive Fatigue Assessment Battery for People with Spinal Cord Injury (CFAB-SCI) and to further our understanding of fatigue in SCI. Methods: Seventy community-dwelling adults with SCI were recruited. The participants completed the CFAB-SCI as well as six additional self-report measures to assess convergent validity with six matching sections of the battery. Convergent validity was assessed via Spearman’s ρ correlation, and internal consistency via Cronbach’s α. Open-ended survey data from the CFAB-SCI was analyzed to explore fatigue using a content analysis approach. Results: A total of 64 participants competed the study. Convergent validity and internal consistency values all exceeded the hypothesized values. Content analysis of text data revealed four major groupings when participants were asked to tell us more about their fatigue: 1) experience with fatigue; 2) impact of fatigue; 3) factors of fatigue; and 4) management of fatigue. Significance: Evidence reveals the complexity of fatigue and supports the validity and reliability of the self-report CFAB-SCI as a comprehensive, clinically useful tool to characterize fatigue in SCI. It will offer people with SCI an understanding of factors that may contribute to their fatigue experience and will direct the treatment decisions of clinicians who are intervening to mitigate the impact of fatigue.

description: Qual è il limite oltre il quale la fruizione di un'opera non può più essere considerata estetica? Quali possono essere considerati i confini del “buon gusto”? Quali meccanismi scattano in noi davanti alla visione di scene spiacevoli, anche se fittizie? A partire da questi interrogativi, quest'opera affronta un'analisi del patetico, disgustoso, orrorifico e osceno, facendo riferimento soprattutto alle riflessioni estetiche nel Settecento, epoca nella quale, per la prima volta, si realizzano studi sul rapporto tra soggettività del piacere e universalità del concetto di gusto, riflettendo sui motivi per cui immagini che nella realtà sarebbero disturbanti, nella finzione artistica possono provocare diletto.

description: «Ein Gespenst geht um in Europa…». L’evocazione umbratile del titolo, schiudendo il campo semantico dello spettro, suggerisce un movimento non del tutto addomesticabile, una dinamica, evanescente e resistente, dell’aggirarsi e dell’incombere: non il filologo, ma le sue spoglie; oppure – e insieme – soltanto un’ombra, del filologo, dovremmo dire, soltanto l’ombra. E così, col passo di uno spettro, avvezzo all’attraversare e al trapassare, la ricerca procede entro e oltre i bordi delle discipline, ascrivibile eppure non circoscrivibile all’ambito della «tematologia letteraria» (p. 1), ma tale da produrre al suo esito, lungo una trama composita di digressioni e ritorni, «una storia culturale del personaggio del filologo e dell’umanista nella letteratura europea del Novecento» (p. 1).

description: L’indagine condotta da Valeria Pala sull’opera landolfiana, con particolare riguardo all’attività di traduttore svolta da Landolfi, appare interessante in ogni suo aspetto; fin dalle prime pagine viene posto in rilievo lo stretto legame tra gli scritti di Landolfi e la cultura russa, oggetto di studio dell’autore dagli anni universitari e fonte di perenne ispirazione delle proprie opere. La crisi del sistema culturale italiano,  forte negli anni in cui Landolfi si dedica all’attività di traduttore, induce diversi intellettuali del tempo alla traduzione di testi stranieri, allo scopo di importare nella cultura nazionale elementi mutuati da altri sistemi culturali; la traduzione prende dunque a configurarsi come strumento utile per fornire agli scrittori italiani nuovi modelli su cui improntare la propria produzione poetica e letteraria.

description: We have performed the astrometry of H2O masers in the Galactic star-forming region Onsala 2 North (ON2N) with the VLBI Exploration of Radio Astrometry.We obtained the trigonometric parallax of 0.261+/-0.009 mas, corresponding to the heliocentric distance of 3.83+/-0.13 kpc. ON2N is expected to be on the solar circle, because its radial velocity with respect to the Local Standard of Rest (LSR) is nearly zero. Using present parallax and proper motions of the masers, the Galactocentric distance of the Sun and the Galactic rotation velocity at the Sun are found to be R_0 = 7.80+/-0.26 kpc and Theta_0 = 213+/-5 km/s, respectively. The ratio of Galactic constants, namely the angular rotation velocity of the LSR can be determined more precisely, and is found to be Omega_0=Theta_0/R_0 = 27.3+/-0.8 km/s/kpc, which is consistent with the recent estimations but different from 25.9 km/s/kpc derived from the recommended values of Theta_0 and R_0 by the International Astronomical Union (1985).

description: Critical properties of lattice gases with nearest-neighbor exclusion are investigated via the adaptive-window Wang-Landau algorithm on the square and simple cubic lattices, for which the model is known to exhibit an Ising-like phase transition. We study the particle density, order parameter, compressibility, Binder cumulant and susceptibility. Our results show that it is possible to estimate critical exponents using Wang-Landau sampling with adaptive windows. Finite-size-scaling analysis leads to results in fair agreement with exact values (in two dimensions) and numerical estimates (in three dimensions).

description: This volume explores the versatility of the concept of pneuma in philosophical and medical theories in the wake of Aristotle’s physics. It offers thirteen separate studies of how the concept of pneuma was used in a range of physical, physiological, psychological, cosmological and ethical inquiries. The focus is on individual thinkers or traditions and the specific questions they sought to address, including early Peripatetic sources, the Stoics, the major Hellenistic medical traditions, Galen, as well as Proclus in Late Antiquity and John Zacharias Aktouarios in the early 14th century. Building on new scholarly approaches and on recent advancements in our understanding of Graeco-Roman philosophy and medicine, the volume prompts a profound re-evaluation of this fluid and adaptable, but crucially important, substance, in antiquity and beyond.

Der Fokus liegt auf individuellen Denkern oder Traditionen und deren spezifischen Fragestellungen, unter ihnen die frühen Peripatetiker, die Stoiker, die großen hellenistischen medizinischen Traditionen, Galen, aber auch der spätantike Proclus und Johann Zacharias Aktouarios im frühen 14. Jh. Auf neue Forschungsansätze und Entwicklungen bezüglich des Forschungsgegenstandes griechischrömische Philosophie und antike Medizin bauend, bietet dieser Sammelband eine profunde Neubewertung dieser fluiden, aber zentralen Substanz, in der Antike und späterer Zeit.

description: To obtain the optimal number of communities is an important problem in detecting community structure. In this paper, we extend the measurement of community detecting algorithms to find the optimal community number. Based on the normalized mutual information index, which has been used as a measure for similarity of communities, a statistic $Ω(c)$ is proposed to detect the optimal number of communities. In general, when $Ω(c)$ reaches its local maximum, especially the first one, the corresponding number of communities \emph{c} is likely to be optimal in community detection. Moreover, the statistic $Ω(c)$ can also measure the significance of community structures in complex networks, which has been paid more attention recently. Numerical and empirical results show that the index $Ω(c)$ is effective in both artificial and real world networks.

Essays on capital markets
Creators: name: Rahman, Nafis
Publisher: name: University of British Columbia
Year: 2016

description: This thesis is a collection of three essays on capital markets. The first essay examines how signals of reputation with non-equity stakeholders affect the market reaction to accounting restatements. Using Corporate Social Responsibility (CSR) rating as a proxy for reputation with non-equity stakeholders, I find significantly less negative market reaction to restatements for firms with better reputation. I also find that high-CSR firms experience smaller earnings-decreases and need to engage in fewer reputation restoration activities. The results suggest that a significant portion of the market value loss triggered by restatements reflects an expectation that the restating firms will face a ‘worsening of terms’ in their future transactions with the non-equity stakeholders, and CSR reputation can dampen this effect. The second essay examines the impact of accounting restatements on the information content of analyst forecast revisions (FRIC). I find that following material restatements that are perceived to be intentional, FRIC increases significantly compared to the pre-restatement period level. The results suggest that investors increase their reliance on analysts when there is uncertainty about the firm and the credibility of management disclosure is compromised. Additional tests reveal that the effect is greater for analysts who are less likely to have close ties with the management. The third essay studies how misaligned language between the investor and the firm contributes to the foreign investor bias. In particular, we document a significant US institutional investor bias against firms located in Quebec relative to firms located in the Rest of Canada (ROC). The differential bias is surprising given that Quebec and the ROC share the same country, federal law, stock exchange, accounting standards, and regulatory filings are prepared in both English and French; and given that US institutional investors are sophisticated investors at close geographic proximity to both Quebec and the ROC. We also contrast the bias against Quebec firms with different levels of French versus English online presence, and we contrast the bias of institutional investors located in the UK versus France, to bolster our conclusion that incongruent languages are a major source of bias.

description: Insulating substrates are crucial for electrical transport study and room temperature application of topological insulator films at thickness of only several nanometers. High quality quantum well films of Bi2Se3, a typical three-dimensional topological insulator, have been grown on α-Al2O3 (sapphire) (0001) by molecular beam epitaxy. The films exhibit well-defined quantum well states and surface states, suggesting the uniform thickness over macroscopic area. The Bi2Se3 thin films on sapphire (0001) provide a good system to study low-dimensional physics of topological insulators since conduction contribution from the substrate is negligibly small.

description: The role of mutualisms in mediating temporal stability in an ecosystem has been debated extensively. Here, we focus on how a ubiquitous mutualism, arbuscular mycorrhiza, influences temporal stability of a key ecosystem process, ecosystem respiration. We discriminated between two forms of temporal stability, temporal variability and resilience, and hypothesized that excluding arbuscular mycorrhiza would be detrimental for both of them. We analyzed a set of 10 parallel manipulation experiments to assess how excluding arbuscular mycorrhiza modulates temporal stability compared to other common experimental factors. We quantified the temporal variability of ecosystem respiration and the resilience to experimental perturbations (i.e., pulses, stresses, and a disturbance) following manipulations of mycorrhizal state. We observed lower temporal variability in the absence of arbuscular mycorrhiza in discord to our main hypothesis. Manipulating arbuscular mycorrhiza had a stronger impact on temporal variability than the pulse (application of urea), the stress (addition of salt), and a disturbance (experimental defoliation) but weaker than excluding primary producers or comparing across different plant species. Resilience to experimental perturbations declined in non‐mycorrhizal microcosms. We present an empirical study on how mutualisms impact temporal stability. Arbuscular mycorrhiza differentially alters temporal variability and resilience, highlighting that generalizing across different forms of temporal stability could be misleading.

description: In this paper we study the numerical passage from the spatially homogeneous Boltzmann equation without cut-off to the Fokker-Planck-Landau equation in the so-called grazing collision limit. To this aim we derive a Fourier spectral method for the non cut-off Boltzmann equation in the spirit of L. Pareschi, B.Perthame, TTSP 25, (1996) and L.Pareschi, G.Russo, SINUM 37, (2000). We show that the kernel modes that define the spectral method have the correct grazing collision limit providing a consistent spectral method for the limiting Fokker-Planck-Landau equation. In particular, for small values of the scattering angle, we derive an approximate formula for the kernel modes of the non cut-off Boltzmann equation which, similarly to the Fokker-Planck-Landau case, can be computed with a fast algorithm. The uniform spectral accuracy of the method with respect to the grazing collision parameter is also proved.

description: Weak lensing surveys exploit measurements of galaxy ellipticities. These measurements are subject to errors which degrade the cosmological information that can be extracted from the surveys. Here we propose a way of using the galaxy data themselves to calibrate the measurement errors. In particular, the cosmic shear field, which causes the galaxies to appear elliptical, also changes their sizes and fluxes. Information about the sizes and fluxes of the galaxies can be added to the shape information to obtain more robust information about the cosmic shear field. The net result will be tighter constraints on cosmological parameters such as those which describe dark energy.

Modelling the X-ray fractional root-mean-squared (FRMS) variability spectra of Active Galactic Nuclei
Creators: name: Mallick, Labani
Publisher: name: Zenodo
Year: 2021

description: Active Galactic Nuclei (AGN) have been of great interest because of their complex broadband electromagnetic spectra and extreme variability ranging from radio to gamma-rays at the time-scales from a few minutes to years depending upon the physical processes they are governed by. In order to understand the complex nature of AGN X-ray variability, I devised a method to model the fractional root-mean-squared (FRMS) variability spectra and measured the variability power in different spectral components. We applied this method to investigate the nature and origin of energy-dependent variability of various Type 1 AGN. In this talk, I will present several studies with the aim of better understanding the variability mechanism and hence the accretion processes onto the supermassive black holes.

description: We present a follow up study of the sensitivity of the Earth's magnetosphere to solar wind activity using a particles-in-cell model [Baraka and Ben Jaffel, 2007], but here during northward IMF. The formation of the magnetospheric cavity and its elongation is obtained with the classical structure of a magnetosphere with parallel lobes. An impulsive disturbance is then applied to the system by changing the bulk velocity of the solar wind to simulate a decrease in the solar wind dynamic pressure followed by its recovery. In response to the imposed disturbance, a gap [abrupt depression] in the incoming solar wind plasma appears moving toward the Earth. The gap's size is a ~15 RE and is comparable to the sizes previously obtained for both Bz<0 and Bz =0. During the initial phase of the disturbance, the dayside magnetopause (MP) expands slower than the previous cases of IMF orientations as a result of the depression. The size of the MP expands nonlinearly due to strengthening of its outer boundary by the northward IMF. Also, during the initial 100 Δt, the MP shrank down from 13.3 RE to ~9.2 RE before it started expanding; a phenomenon that was also observed for southern IMF conditions but not during the no IMF case. As soon as they felt the solar wind depression, cusps widened at high altitude while dragged in an upright position. For the field's topology, the reconnection between magnetospheric and magnetosheath fields is clearly observed in both northward and southward cusps areas. Also, the tail region in the northward IMF condition is more confined, in contrast to the fishtail-shape obtained in the southward IMF case. An X-point is formed in the tail at ~110 RE compared to ~103 RE and ~80 RE for Bz =0 and Bz <0 respectively. Our findings are consistent with existing reports from many space observatories for which predictions are proposed to test furthermore our simulation technique.

No alarm : hypersonic weapons development and the shifting logics of arms control
Creators: name: Garcia, Omar
Publisher: name: University of British Columbia
Year: 2016

description: Why has the development of hypersonic weapons systems provoked such little concern among arms control organizations relative to that raised by the development of autonomous weapons systems and soldier-enhancing technologies, on one hand, and past weapons research programs with similar strategic implications, like Ronald Reagan’s Strategic Defense Initiative, on the other? This thesis employs social network analysis and case comparisons to argue that a historical shift in arms control imperatives has shifted attention from weapons systems of interstate strategic consequence to weapons systems of individual consequence. Specifically, the shift from the Cold War arms control paradigm to a humanitarian arms control agenda after 1991 has led to the prioritization of efforts to limit or ban weapons that indiscriminately or disproportionally harm individual human lives. As a result, weapons systems that threaten to upset the military balance between the leading global military powers—like hypersonic weapons systems—no longer cause as much concern as was the case for most of the past century and a half.

description: One prediction of particle acceleration in the supernova remnants in the magnetic wind of exploding Wolf Rayet and Red Super Giant stars is that the final spectrum is a composition of a spectrum $E^{-7/3}$ and a polar cap component of $E^{-2}$ at the source. This polar cap component contributes to the total energy content with only a few percent, but dominates the spectrum at higher energy. The sum of both components gives spectra which curve upwards. The upturn was predicted to occur always at the same rigidity. An additional component of cosmic rays from acceleration by supernovae exploding into the Inter-Stellar Medium (ISM) adds another component for Hydrogen and for Helium. After transport the predicted spectra $J(E)$ for the wind-SN cosmic rays are $E^{-8/3}$ and $E^{-7/3}$; the sum leads to an upturn from the steeper spectrum. An upturn has now been seen. Here, we test the observations against the predictions, and show that the observed properties are consistent with the predictions. Hydrogen can be shown to also have a noticeable wind-SN-component. The observation of the upturn in the heavy element spectra being compatible with the same rigidity for all heavy elements supports the magneto-rotational mechanism for these supernovae. This interpretation predicts the observed upturn to continue to curve upwards and approach the $E^{-7/3}$ spectrum. If confirmed, this would strengthen the case that supernovae of very massive stars with magnetic winds are important sources of Galactic cosmic rays.

description: We investigate the Nernst effect in a mesoscopic two-dimensional electron system (2DES) at low magnetic fields, before the onset of Landau level quantization. The overall magnitude of the Nernst signal agrees well with semi-classical predictions. We observe reproducible mesoscopic fluctuations in the signal which diminish significantly with an increase in temperature. We also show that the Nernst effect exhibits an anomalous component which is correlated with an oscillatory Hall effect. This behavior may be able to distinguish between different spin-correlated states in the 2DES.

Adiabatic & non-adiabatic perturbation theory for coherence vector description of neutrino oscillations

description: The standard wave function approach for the treatment of neutrino oscillations fails in situations where quantum ensembles at a finite temperature with or without an interacting background plasma are encountered. As a first step to treat such phenomena in a novel way, we propose a unified approach to both adiabatic and non-adiabatic two-flavor oscillations in neutrino ensembles with finite temperature and generic (e.g. matter) potentials. Neglecting effects of ensemble decoherence for now we study the evolution of a neutrino ensemble governed by the associated Quantum Kinetic Equations, which apply to systems with finite temperature. The Quantum Kinetic Equations are solved formally using the Magnus expansion and it is shown that a convenient choice of the quantum mechanical picture (e.g. the interaction picture) reveals suitable parameters to characterize the physics of the underlying system (e.g. an effective oscillation length). It is understood that this method also provides a promising starting point for the treatment of the more general case in which decoherence is taken into account.

description: We computed a comprehensive set of theoretical ultraviolet spectra of hot, massive stars with the radiation-hydrodynamics code WM-Basic. This model atmosphere and spectral synthesis code is optimized for computing the strong P Cygni-type lines originating in the winds of hot stars, which are the strongest features in the ultraviolet spectral region. The computed set is suitable as a spectral library for inclusion in evolutionary synthesis models of star clusters and star-forming galaxies. The chosen stellar parameters cover the upper left Hertzsprung-Russell diagram at L >~ 10^2.75 Lsun and T_eff >~ 20,000 K. The adopted elemental abundances are 0.05 Zsun, 0.2 Zsun, 0.4 Zsun, Zsun, and 2 Zsun. The spectra cover the wavelength range from 900 to 3000 Å and have a resolution of 0.4 Å. We compared the theoretical spectra to data of individual hot stars in the Galaxy and the Magellanic Clouds obtained with the International Ultraviolet Explorer (IUE) and Far Ultraviolet Spectroscopic Explorer (FUSE) satellites and found very good agreement. We built a library with the set of spectra and implemented it into the evolutionary synthesis code Starburst99 where it complements and extends the existing empirical library towards lower chemical abundances. Comparison of population synthesis models at solar and near-solar composition demonstrates consistency between synthetic spectra generated with either library. We discuss the potential of the new library for the interpretation of the rest-frame ultraviolet spectra of star-forming galaxies. Properties that can be addressed with the models include ages, initial mass function, and heavy-element abundance. The library can be obtained both individually or as part of the Starburst99 package.

description: We present an implementation of the next-to-leading order vector boson plus one jet production process in hadronic collision in the framework of POWHEG, which is a method to implement NLO calculations within a Shower Monte Carlo context. All spin correlations in the vector boson decay products have been taken into account. The process has been implemented in the framework of the POWHEG-BOX, an automated computer code for turning a NLO calculation into a shower Monte Carlo program. We present phenomenological results for the case of the Z/gamma plus one jet production process, obtained by matching the POWHEG calculation with the shower performed by PYTHIA, for the LHC, and we compare our results with available Tevatron data.

description: In the field of assembly automation with industrial robots the research on the application of artificial intelligence techniques is getting increasing importance. This paper describes the hierarchical structure of a knowledge—based sensory-controlled robot assembly system under development which is capable to plan and execute assembly tasks under real—time requirements. The hybrid knowledge representation scheme combining the rule—based and object—oriented approach to represent the assembly domain—specific knowledge is discussed. Furtheron, the knowledge processing concept based upon the representation scheme is explained. A first prototype of the system has been implemented in a real robotic test—bed. Several peg/hole part mating sequences validated the capability of the system to execute assembly tasks in an uncertain environment using sensory information.
