Person authentication using EEG brainwave signals
Creators: name: He, Chen
Publisher: name: University of British Columbia
Year: 2010

description: Studies have shown that the electroencephalogram (EEC) recordings have unique pattern for each individual and thus have potential for biometric applications. There are two major problems associated with EEC biometrics. One is that the large EEG features size and the relatively limited EEG data size make it difficult to train a robust model; the other is that the signals from EEG scalp may not be reliable in many situations. Thus in this thesis we proposed new methods for increasing the accuracy and robustness of EEC-based authentication systems. First, to address the concern of the high dimensionality of EEC features, we proposed a novel dimension reduction method of EEG features based on the Fast Johnson-Lindeustrauss Transform (FJLT). We showed that this method has potential of mapping EEG features from a high dimension space to a lower one while keeping discrimination power between the features of subjects. The features we used are Multivariate Autoregressive (mAR) coefficients. We tested this method on a motor task related EEG data set. Second, to increase the reliability of scalp EEC signals, we employed an Independent Component Analysis (ICA)-based approach in our authentication procedure, with the assumption that EEG recordings are linear combinations of the underlying brain source signals. We estimated the Independent Components (ICs) from several physical regions on the scalp and determine the Dominating Independent Components (DIC) in the corresponding regions. Then we extracted the Univariate Autoregressive (AR)coefficients from DICs as features. We tested our algorithm on two data sets, a motor task related EEC data set and an EEC data set of P300 potential. The proposed algorithm appeared to be promising, and when applied to EEG data collected from different days yields better performance than other methods. This relative consistence over time is essential in person authentication systems.

description: Informal learning environments are critical to supplemental student learning outside the formal classroom space. The problem the research addressed is the lack of informal STEM learning programs for underrepresented minority, female, urban, and rural students. The purpose of this research was to demonstrate the effect informal STEM learning has on the population’s self-efficacy and interest in STEM. The intervention for this research study was a seven-day informal learning summer camp involving five STEM projects from around the field and aligned with relevant fields offered by the Purdue University Polytechnic Institute. The participants worked in large and small group sessions with program volunteers to gain foundational learning outcomes. The outcome was measured using the STEM-CIS survey instrument in a pre-and post-testing format. The data was coded from the Likert scale and then used to calculate statistics and effect size for Likert-style data. The intervention was performed during the summer of 2021 and yielded results showing that students felt the effect of having role models and professionals involved in the STEM field.

description: The Hopf conjecture states that an even-dimensional, positively curved Riemannian manifold has positive Euler characteristic. We prove this conjecture under the additional assumption that a torus acts by isometries and has dimension bounded from below by a logarithmic function of the manifold dimension. The main new tool is the action of the Steenrod algebra on cohomology.
A survey of urban Canadian animal control practices : the effect of enforcement and resourcing on the reported dog bite rate
Creators: name: Clarke, Nancy Margaret
Publisher: name: University of British Columbia
Year: 2010

description: Dog bites are a serious cause of human injury. Data from the United States of America indicate that about 1.8% of people receive bites each year, and the rate is thought to be increasing disproportionately faster than the dog population. The Canadian dog bite issue is not well documented although it is a public safety concern. Increased enforcement, education and breed-specific legislation have been used in attempts to lower dog bite incidence. However, the decentralization of the animal control system in Canada, the lack of standardized terms, and the lack of mandated reporting have resulted in unreliable information from which to evaluate the effectiveness of the strategies. The purposes of this exploratory study were to identify the reported dog bite rate in urban Canadian jurisdictions and to identify animal control strategies that may effectively reduce dog bite incidence. Thirty-six municipalities responded to a questionnaire about animal control resourcing, enforcement, and reported dog bites. The study found a median of 1.8 reported dog bites per 10,000 people, far below the number of “non-household” dog bites (bites caused by dogs not known to the victim) expected on the basis of other studies. Enforcement activities varied widely between municipalities, with some distinct regional differences. Contrary to initial expectations, the reported dog bite rate was positively correlated with most indicators of enforcement. This positive correlation is probably due to a greater proportion of bites being reported in municipalities with more active enforcement. However, municipalities with very high ticketing rates had far fewer reported dog bites than would be expected based on the linear relationships. The results are best explained by a regression of reported dog bites on ticketing rate consisting of a positive linear component and negative quadratic component. Increased ticketing appears to have increased the reporting rate (causing a positive linear regression) and reduced the actual rate of biting (causing a negative quadratic regression), at least when enforcement was high. Within the limitations of this study, the data provided no evidence to suggest that breed-specific legislation is effective in reducing the rate of reported dog bites.

Image-based visual servoing with hybrid camera configuration for robust robotic grasping
Creators: name: Zhang, Guan-Lu
Publisher: name: University of British Columbia
Year: 2010

description: A challenging anthropomorphic characteristic which a robotic manipulator should acquire is vision. When first introduced to manufacturing and material-handling industries, robots were taught to move “blindly” in a structured environment where the position and the orientation of the manipulated object were assumed to be known. Since then, a spectrum of visual servoing techniques has been developed to increase the versatility and accuracy of the robotic manipulators for carrying out tasks in less structured environments. In particular, the concept of continuous motion control of robotic systems using a visual feedback loop has been applied recently to unstructured environments. In the work presented in this thesis, a functioning mobile manipulator platform, named Autonomous Intelligent Mobile Manipulator (AIMM) with a hybrid camera configuration has been developed. This platform is a member of the cooperative heterogeneous mobile robotic team at the Industrial Automation Laboratory (IAL) of the University of British Columbia (UBC). Given the increasing threat of terrorism and natural disasters around the world, the encompassing research explores new robotic solutions for search and rescue applications. Specifically, the LkL robotics subgroup develops robotic capabilities that can assist or even replace human rescuers in situations that involve life threatening risks. The main contribution of the work in this thesis can be summarized by its two aspects: hardware and control scheme. The developed mobile manipulator consists of a light-weight yet capable manipulator, a mobile robotic base, and a hybrid camera configuration using both a monocular camera and a stereo camera. The classical image-based visual servoing scheme has been improved by techniques of depth estimation and neural network-based grasping. In the present work, both the platform and the control scheme have been tested in real-life scenarios where multiple robots complete a complex task of object handling in an unstructured environment. Future directions in platform upgrade and visual servoing research are proposed as well.

description: We report the discovery of a unique object, BD+48 740, a lithium overabundant giant with A(Li)=2.33 +/- 0.04 (where A(Li) = log(n_Li/n_H) + 12), that exhibits radial velocity (RV) variations consistent with a 1.6 M_J companion in a highly eccentric, e = 0.67 +/- 0.17 and extended, a=1.89 AU (P=771 d), orbit. The high eccentricity of the planet is uncommon among planetary systems orbiting evolved stars and so is the high lithium abundance in a giant star. The ingestion by the star of a putative second planet in the system originally in a closer orbit, could possibly allow for a single explanation to these two exceptional facts. If the planet candidate is confirmed by future RV observations, it might represent the first example of the remnant of a multiple planetary system possibly affected by stellar evolution.

description: We investigate vortices in LiFeAs using scanning tunneling microscopy/spectroscopy. Zero-field tunneling spectra show two superconducting gaps without detectable spectral weight near the Fermi energy, evidencing fully-gapped multi-band superconductivity. We image vortices in a wide field range from 0.1 T to 11 T by mapping the tunneling conductance at the Fermi energy. A quasi-hexagonal vortex lattice at low field contains domain boundaries which consist of alternating vortices with unusual coordination numbers of 5 and 7. With increasing field, the domain boundaries become ill-defined, resulting in a uniformly disordered vortex matter. Tunneling spectra taken at the vortex center are characterized by a sharp peak just below the Fermi energy, apparently violating particlehole symmetry. The image of each vortex shows energy-dependent 4-fold anisotropy which may be associated with the anisotropy of the Fermi surface. The vortex radius shrinks with decreasing temperature and becomes smaller than the coherence length estimated from the upper critical field. This is direct evidence of the Kramer-Pesch effect expected in a clean superconductor.

The impact of health beliefs and family asthma management on biological outcomes in youth with asthma
Creators: name: Walker, Hope Alayne
Publisher: name: University of British Columbia
Year: 2010

description: Childhood asthma is a chronic inflammatory disease, with symptoms likely affected by physical, environmental and social factors. With regard to social factors, previous research has linked asthma management and beliefs to morbidity outcomes in children with asthma. In two studies, it was tested whether beliefs about and management of one’s illness would predict biological outcomes cross-sectionally (in Study 1), and longitudinally over 18 months (in Study 2) in a sample of children with asthma. Associations of asthma management-related beliefs and behaviors with immune markers and clinical outcomes were examined in a sample of 66 children with asthma (ages 9-18) in Study 1, and longitudinal associations of asthma management-related beliefs and behaviors with changes in asthma-relevant biological markers in a subsample of 40 children with asthma in Study 2. Children and parents were interviewed about asthma management beliefs and behaviors. In Study 1, immune measures included stimulated production of cytokines implicated in asthmatic airway inflammation, eosinophil counts, and IgE levels. Clinical outcomes included pulmonary function, symptoms, beta agonist use, and physician contacts. In Study 2, asthma outcomes included lung function (FEV ₁%), eosinophil counts, and daily cortisol measured at two time points, 18 months apart. In Study 1, children’s reports of greater conceptual understanding of asthma, parents’ reports of quicker responses to asthma symptoms, and children’s and parents’ reports of more balanced integration of asthma into daily life were all associated with reduced inflammatory profiles. Inflammatory profiles were found to be a statistically significant pathway linking asthma beliefs and behaviors to clinical outcomes. In Study 2, children with a less sophisticated disease belief (the “no symptoms, no asthma” belief) displayed eosinophil counts that increased over time, controlling for baseline levels. Poorer family asthma management was associated with increasing eosinophil counts over time. Poorer child asthma management was associated with cortisol output that declined over time. Families who reported poorer collaboration with their physician had children who displayed worsening lung function over time. These findings suggest that interventions aimed at teaching families better asthma management approaches and more accurate disease beliefs may have the potential to alter biological profiles in children with asthma.

description: We report neutron scattering measurements of critical magnetic excitations in the weakly ferromagnetic superconductor UCoGe. The strong non-Landau damping of the excitations we observe, although unusual has been found in another related ferromagnet, UGe2 at zero pressure. However, we also find there is a significant anisotropy of the magnetic correlation length in UCoGe that contrasts with an almost isotropic length for UGe2. The values of the magnetic correlation length and damping are found to be compatible with superconductivity on small Fermi surface pockets. The anisotropy may be important to explain why UCoGe is a superconductor at zero pressure while UGe2 is not.

Combining Candle Patterns and LSTM models topredict stocks

description: The stock markets is always suffering from ups and downs. Investors apply their money,
 mostly in companies stocks, and expect a capital appreciation over time. A good investor
 has theoretical and practical knowledge about the investment market and can make risk
 assessments of a stock, analyzing previous trends and behaviors.
 However, due to the high number of variables that can impact the performance of a
 business, it is not easy to identify patterns that indicate the best time to buy or sell
 shares. In order to operate in this complex environment, investors have used advanced
 forecasting and graphical analysis tools to assist in the decision-making process.
 This work proposes methods to help that decision-making process in financial applications
 and it is based on two different strategies for buying and selling stocks. The first uses only
 the LSTM neural network to make buying and selling decisions. The second, in addition
 to the neural network, also use candle patterns to influence the decisions. In that case,
 the patterns will only influence when the LSTM indicates that a buy or sell transaction
 should take place.
 The strategy that uses only LSTM has proven to be effective in stocks that already showed
 a growth trend. When it was combined with the Candle patterns, the result was a safer
 strategy. It showed a lower yield, but reduced losses and the number of operations.

description: Using N-body simulations, we studied the detailed evolution of central stellar velocity dispersion, σ, during dissipationless binary mergers of galaxies. Stellar velocity dispersion was measured using the common mass-weighting method as well as a flux-weighting method designed to simulate the technique used by observers. A toy model for dust attenuation was introduced in order to study the effect of dust attenuation on measurements of σ. We found that there are three principal stages in the evolution of σ in such mergers: oscillation, phase mixing, and dynamical equilibrium. During the oscillation stage, σ undergoes damped oscillations of increasing frequency. The oscillation stage is followed by a phase mixing stage during which the amplitude of the variations in σ is smaller and more chaotic than in the oscillation stage. Upon reaching dynamical equilibrium, σ assumes a stable value. We used our data regarding the evolution of σ during mergers to characterize the scatter inherent in making measurements of σ in non-quiescent systems. In particular, we found that σ does not fall below 70% nor exceed 200% of its final, quiescent value during a merger and that a random measurement of σ in such a system is much more likely to fall near the equilibrium value than near an extremum. Our toy model of dust attenuation suggested that dust can systematically reduce observational measurements of σ and increase the scatter in σ measurements.

description: We report measurements of the neutron diffuse scattering in a single crystal of the relaxor ferroelectric material 95.5%Pb(Zn1/3Nb2/3)O3-4.5%PbTiO3 (PZN-4.5%PT). We show that the diffuse scattering at high temperatures has a quasielastic component with energy width $\agt$ 0.1 meV. On cooling the total diffuse scattering intensity increases, but the intensity and the energy width of the quasielastic component gradually diminish. At 50 K the diffuse scattering is completely static (i.e.the energy width lies within the limits of our instrumental resolution). This suggests that the dynamics of the short-range correlated atomic displacements associated with the diffuse scattering freeze at low temperature. We find that this depends on the wave vector q as the quasielastic diffuse scattering intensities associated with <001> (T1-type) and <110> (T2-type) atomic displacements vary differently with temperature and electric field.

description: CD4+ T cells are typically considered as ‘helper’ or ‘regulatory’ populations that support and orchestrate the responses of other lymphocytes. However, they can also develop potent granzyme (Gzm)-mediated cytotoxic activity and CD4+ cytotoxic T cells (CTLs) have been amply documented both in humans and in mice, particularly in the context of human chronic infection and cancer. Despite the established description of CD4+ CTLs, as well as of the critical cytotoxic activity they exert against MHC class II-expressing targets, their developmental and memory maintenance requirements remain elusive. This is at least in part owing to the lack of a murine experimental system where CD4+ CTLs are stably induced. Here, we show that viral and bacterial vectors encoding the same epitope induce distinct CD4+ CTL responses in challenged mice, all of which are nevertheless transient in nature and lack recall properties. Consistent with prior reports, CD4+ CTL differentiation is accompanied by loss of TCF-1 expression, a transcription factor considered essential for memory T cell survival. Using genetic ablation of Tcf7, which encodes TCF-1, at the time of CD4+ T cell activation, we further show that, contrary to observations in CD8+ T cells, continued expression of TCF-1 is not required for CD4+ T cell memory survival. Whilst Tcf7-deficient CD4+ T cells persisted normally following retroviral infection, the CD4+ CTL subset still declined, precluding conclusive determination of the requirement for TCF-1 for murine CD4+ CTL survival. Using xenotransplantation of human CD4+ T cells into murine recipients, we demonstrate that human CD4+ CTLs develop and persist in the same experimental conditions where murine CD4+ CTLs fail to persist. These observations uncover a species-specific defect in murine CD4+ CTL persistence with implications for their use as a model system.

stratosphere

description: ORISON is an H2020 European-funded project created to carry out a feasibility and design study of an astronomically-oriented balloon facility that could deploy one or several small-to-medium-sized stabilized telescopes and a suite of other scientific instruments as light payloads to do state of the art research at acceptable costs.

Advantages of stratospheric observations of meteors:

•Closer to the source

•No clouds blocking the view

•More atmospheric volume available due to transparency of the stratosphere -> larger statistics.

•Interplanetary dust collecting

•Less Rayleigh/Mie scattering (Moon/Sun/light pollution)

•Daytime observation.

•Inside or underneath the event

•Flexibility (new tech)

•Cheaper (100 k€ vs 1 M€)

•Low sky brightness

•UV, Visible, IR and Radio transparent

Other advantages:

•Low cost of development (vs NASA and JAXA probes)

•Fast development

•Synergies with other scientific cases

•More flexibility on location

•Missions from 2 h to 100+ days

description: We investigate zero and finite temperature properties of the one-dimensional spin-glass model for vector spins in the limit of an infinite number m of spin components where the interactions decay with a power, σ, of the distance. A diluted version of this model is also studied, but found to deviate significantly from the fully connected model. At zero temperature, defect energies are determined from the difference in ground-state energies between systems with periodic and antiperiodic boundary conditions to determine the dependence of the defect-energy exponent θon σ. A good fit to this dependence is θ=3/4-σ. This implies that the upper critical value of σis 3/4, corresponding to the lower critical dimension in the d-dimensional short-range version of the model. For finite temperatures the large m saddle-point equations are solved self-consistently which gives access to the correlation function, the order parameter and the spin-glass susceptibility. Special attention is paid to the different forms of finite-size scaling effects below and above the lower critical value, σ=5/8, which corresponds to the upper critical dimension 8 of the hypercubic short-range model.

An extensive series of numerical studies based on the finite element method is performed covering all load combinations and plating configurations relevant for the shipbuilding industry. These studies are used to investigate the mechanics of plating collapse and to evaluate existing proofs of plate capacity. In order to satisfy both qualitative and quantitative acceptance criteria, a new proof of plate capacity under combined in-plane loads is developed. Practical application of the proof in design is presented.

description: Die Privatisierung von Religiösität und die damit verbundene semantische Diskrepanz
zwischen kirchlich-biblischer Semantik und Jugendsprache stellt seit
über zwanzig Jahren neue Anforderungen für nachhaltige religiöse Lernprozesse
an die Religionspädagogik und die Korrelationsdidaktik. Durch fehlende religiöse
Sozialisation fehlen Kindern und Jugendlichen oft religiöse Vorerfahrungen und
Vokabeln, weshalb sie bei korrelativen Transferleistungen im Religionsunterricht
benachteiligt sind. Nachhaltiges Lernen wird bereits durch die fehlende Aktivierung
von Vorwissen aufgrund semantischer Diskrepanzen im Sprachverarbeitungsprozess
verhindert.

description: The Carnegie-Irvine Galaxy Survey (CGS) is a long-term program to investigate the photometric and spectroscopic properties of a statistically complete sample of 605 bright (B_T < 12.9 mag), southern (Dec. < 0) galaxies using the facilities at Las Campanas Observatory. This paper, the first in a series, outlines the scientific motivation of CGS, defines the sample, and describes the technical aspects of the optical broadband (BVRI) imaging component of the survey, including details of the observing program, data reduction procedures, and calibration strategy. The overall quality of the images is quite high, in terms of resolution (median seeing 1"), field of view (8.9' X 8.9'), and depth (median limiting surface brightness 27.5, 26.9, 26.4, and 25.3 mag/arcsec2 in the B, V, R, and I bands, respectively). We prepare a digital image atlas showing several different renditions of the data, including three-color composites, star-cleaned images, stacked images to enhance faint features, structure maps to highlight small-scale features, and color index maps suitable for studying the spatial variation of stellar content and dust. In anticipation of upcoming science analyses, we tabulate an extensive set of global properties for the galaxy sample. These include optical isophotal and photometric parameters derived from CGS itself, as well as published information on multiwavelength (ultraviolet, U-band, near-infrared, far-infrared) photometry, internal kinematics (central stellar velocity dispersions, disk rotational velocities), environment (distance to nearest neighbor, tidal parameter, group or cluster membership), and H I content. The digital images and science-level data products will be made publicly accessible to the community.

A modified "Type I migration" model for propeller moons in Saturn's rings

description: We propose a mechanism for the observed non-keplerian motion (Tiscareno et al. 2010, ApJL) of "propeller" moons embedded in Saturn's rings. Our mechanism, in which radial variations in surface density -- external to, and unaffected by, the embedded moon -- result in an equilibrium semimajor axis for the moon due to "Type I" angular momentum exchange (Crida et al. 2010, AJ), provides a good fit to the observations. Future observations should distinguish between our model and others recently proposed.

description: Topographic Rossby waves trapped at a cylindrical seamount are studied under conditions where a linear theory applies. In the barotropic approximation an exact analytical solution valid for obstacles of arbitrary height is derived, baroclinic effects are included approximately. The frequency of the topographic waves is proportionally to the inertial frequency and the relative obstacle height. Stratification increases the wave frequency and restricts the vertical extend of the pressure perturbation.

For a homogeneous upstream flow starting at t = 0 the pressure perturbation and the flow field are calculated. The pressure perturbation encircles the obstacle clockwise as a dipole like structure, the velocity field is approximately in geostrophic balance. Due to friction the pressure perturbation becomes stationary after some time in correspondence to a very small flow velocity over the top of the obstacle.

The analytical results are compared with the free surface GFDL-modeL For barotropic conditions there is a quantitative agreement of analytical and numerical results. In the baroclinic case especially for small seamounts a difference is found between the analytically and numerically calculated spectrum. This can be traced back to the coupling of low and high order vertical modes which are not resolved by the finite model grid.
description: Die Anregung topographischer Rossby-Wellen an einem zylindrischen unterseeischen Berg wird analytisch und mit numerischen Experimenten für den Fall untersucht, daß eine lineare Theorie anwendbar ist. Unter barotropen Bedingungen wird eine exakte analytische Lösung, gültig für Berge beliebiger Höhe, angegeben, barokline Effekte werden näherungsweise berücksichtigt. Die Frequenz der topographischen Wellen ist zur Trägheitsfrequnz und zur relativen Höhe des Bergs proportional. Durch die Schichtung wird die topographische Frequenz vergrößert und die Druckstörung am Boden lokalisiert.

Für eine bei t = 0 beginnende homogene Anströmung werden die Druckstörung und das Geschwindigkeitsfeld berechnet. Die Druckstörung umläuft den Berg im Uhrzeigersinn als dipolartige Struktur, das Geschwindigkeitsfeld ist näherungsweise geostrophisch balanciert. Durch Reibung stellt sich ein stationärer Zustand mit einer sehr kleinen Stromgeschwindigkeit über dem Berg ein.

Die analytische Theorie wird mit dem GFDL-Modell verglichen. Unter barotropen Bedingungen ist die quantitative Übereinstimmung zwischen beiden exzellent. Im baroklinen Fall gibt es Abweichungell im Spektrum. Diese können auf im numerischen Modell nicht aufgelöste vertikale Moden höherer Ordnung zurückgeführt werden, die durch die Bodenrandbedingung an den barotropen sowie an niedrige vertikale Moden gekoppelt sind.

description: Gerade in der Schule, einem Ort, der die persönliche Entfaltung und Weiterentwicklung
der SchülerInnen ermöglichen soll, machen nicht wenige Jugendliche
Viktimisierungserfahrungen – wie verschiedene empirisch-quantitative Studien
eindrücklich belegen. In diesem Beitrag werden allerdings empirisch-qualitative
Studien ins Zentrum gestellt, um Erkenntnisse über diese Erfahrungen aus der
Binnenperspektive Betroffener gewinnen zu können. Annäherung an und Auswertung
der retrospektiven Schilderungen erfolgen sowohl mit einem Interesse
am einzelnen Individuum – mit Fokus auf das Erleben solcher Geschehnisse und
deren Auswirkungen für die Betroffenen – als auch mit einer systemischen Aufmerksamkeit
– mit Fokus auf Bedingungen des Zustandekommens dieser Dynamiken
und deren Bedeutung für das soziale Gefüge. Davon ausgehend werden
angesichts dieser allgemeinpädagogischen Herausforderung religionspädagogische
Perspektiven entwickelt.

description: In this paper, we have modeled the routing over- head generated by three reactive routing protocols; Ad-hoc On-demand Distance Vector (AODV), Dynamic Source Routing (DSR) and DYnamic MANET On-deman (DYMO). Routing performed by reactive protocols consists of two phases; route discovery and route maintenance. Total cost paid by a protocol for efficient routing is sum of the cost paid in the form of energy consumed and time spent. These protocols majorly focus on the optimization performed by expanding ring search algorithm to control the flooding generated by the mechanism of blind flooding. So, we have modeled the energy consumed and time spent per packet both for route discovery and route maintenance. The proposed framework is evaluated in NS-2 to compare performance of the chosen routing protocols.
