Comparison of acceleration methods of matrix calculations in embedded systems
Creators: name: Götze, Johannes
Publisher: name: Embedded Selforganising Systems
Year: 2019

description: In today's algorithms for sound localization techniques, matrix calculations are ubiquitous. Therefore, this work deals with the analysis of matrix calculations and their possible realization on embedded systems. For this purpose, common acceleration technologies such as processors, GPU processing and acceleration with the help of FPGAs are compared. The results show that a graphics chip is capable to accelerate such a matrix vector multiplication compared to an implementation on a processor. Therefore a runtime of an implementation on an FPGA cannot be achieved by a GPU.

Modeling the morphology evolution of organic solar cells
Creators: name: Bergermann, Kai
Publisher: name: GAMM Archive for Students
Year: 2019

description: Organic solar cells present a promising alternative for the generation of solar energy at lower material and production costs compared to widely used silicon-based solar cells. The major drawback of organic solar cells currently is a lower rate of energy conversion. Thus many research projects aim to improve the achievable efficiency. In this work a phase field model is used to mathematically describe the morphology evolution of the active layer composed of polymer as electron-donor and fullerene as electron-acceptor. The derivation of a chemical potential term and a surface energy term for the polymer-fullerene solution using the Flory-Huggins theory forms the basis to employ the Cahn-Hilliard equation. After including several specifics of the application in this non-linear partial differential equation of fourth order, an implementation of the model using the FEM solver software FEniCS provides some simulation results that qualitatively match results from the literature.

Year: 2020

description: Violation of parity symmetry gives rise to various physical phenomena such as nonlinear transport and cross-correlated responses. In particular, the nonlinear conductivity has been attracting a lot of attentions in spin-orbit coupled semiconductors, superconductors, topological materials, and so on. In this paper we present theoretical study of the nonlinear conductivity in odd-parity magnetic multipole ordered systems whose $\mathcal{PT}$-symmetry is essentially distinct from the previously studied acentric systems. Combining microscopic formulation and symmetry analysis, we classify the nonlinear responses in the $\mathcal{PT}$-symmetric systems as well as $\mathcal{T}$-symmetric (non-magnetic) systems, and uncover nonlinear conductivity unique to the odd-parity magnetic multipole systems. A giant nonlinear Hall effect, nematicity-assisted dichroism and magnetically-induced Berry curvature dipole effect are proposed and demonstrated in a model for Mn-based magnets.

description: The low-rank alternating direction implicit (LR-ADI) iteration is an effective method for solving large-scale Lyapunov equations. In the software library pyMOR, solutions to Lyapunov equations play an important role when reducing a model using the balanced truncation method. In this article we introduce the LR-ADI iteration as well as pyMOR, while focusing on its features which are relevant for integrating the iteration into the library. We compare the run time of the iteration's pure pyMOR implementation with those achieved by external libraries available within the pyMOR framework.

Enhancing SAR ship wake detection with motion estimates from along-track interferometry
Creators: name: Ngo, Terry
Publisher: name: University of British Columbia
Year: 2009

description: A difficult problem in remote sensing is the detection of ships on the open ocean. For almost two decades, experimental spaceborne and airborne Synthetic Aperture Radars (SAR) have been used to image ships. However, SAR is inherently limited in (automated) ship detection because it relies on a single parameter, the radar Backscatter, to distinguish faint, small ship signatures from background. Along-Track Interferometry, a recently developed technique that uses two time displaced SAR images (from two alongtrack displaced antennas) to extract velocity estimates of the surface, holds some promise in enhancing the capability of SAR. In this study, we examined the Along-Track Interferometry technique in detail and attempted to assign quantitative measures of its enhancement potential to SAR in ship wake detection. Specifically, we used representative data from an experimental airborne SAR ATI, the Canada Centre for Remote Sensing (CCRS) CV580 C-Band SAR ATI, to examine the effects of ATI processing on: a) the visual appearance of Backscatter and motion signatures of ships and ship wakes in magnitude and phase components of ATI images b) the (quantitative) detectability of ships and their wakes by Backscatter and motion; and c) the characteristics of the Backscatter and motion signatures, such as their spectra, coherence, and signal distribution. And we attempted to determine from our analysis and simulation/modeling, a quantitative measure of the potential of ATI to enhance SAR's performance in ship detection. The results of this study suggest that Along Track Interferometry is capable of enhancing ship wake detection. Specifically, we found that: a) airborne SAR ATI is able to estimate differential (radial) velocity with sufficient accuracy to detect appreciable disturbances of the velocity field of the ocean, and that b) ship wakes, under the conditions of the data collected, were able to sufficiently disturb the velocity field of the ocean surface to be discriminated from ambient ocean structure. This study also suggests that in some circumstances, certain ocean features which may not have been detectable from its Backscatter by a conventional SAR, could be detected from its motion by ATI. And lastly, this study demonstrates that the additional, and in some cases singularly unique, motion information provided by ATI, when fused or combined with conventional Backscatter information, can indeed yield improved detection of ships and wakes overall by the SAR sensor.

description: We present ComCTQMC, a GPU accelerated quantum impurity solver. It uses the continuous-time quantum Monte Carlo (CTQMC) algorithm wherein the partition function is expanded in terms of the hybridisation function (CT-HYB). ComCTQMC supports both partition and worm-space measurements, and it uses improved estimators and the reduced density matrix to improve observable measurements whenever possible. ComCTQMC efficiently measures all one and two-particle Green's functions, all static observables which commute with the local Hamiltonian, and the occupation of each impurity orbital. ComCTQMC can solve complex-valued impurities with crystal fields that are hybridized to both fermionic and bosonic baths. Most importantly, ComCTQMC utilizes graphical processing units (GPUs), if available, to dramatically accelerate the CTQMC algorithm when the Hilbert space is sufficiently large. We demonstrate acceleration by a factor of over 600 (100) in a simulation of $δ$-Pu at 600 K with (without) crystal fields. In easier problems, the GPU offers less impressive acceleration or even decelerates the CTQMC. Here we describe the theory, algorithms, and structure used by ComCTQMC in order to achieve this set of features and level of acceleration.

description: We present detailed luminosity profiles of the young massive clusters M82-F, NGC 1569-A, and NGC 1705-1 which show significant departures from equilibrium (King and EFF) profiles. We compare these profiles with those from N-body simulations of clusters which have undergone the rapid removal of a significant fraction of their mass due to gas expulsion. We show that the observations and simulations agree very well with each other suggesting that these young clusters are undergoing violent relaxation and are also losing a significant fraction of their stellar mass. That these clusters are not in equilibrium can explain the discrepant mass-to-light ratios observed in many young clusters with respect to simple stellar population models without resorting to non-standard initial stellar mass functions as claimed for M82-F and NGC 1705-1. We also discuss the effect of rapid gas removal on the complete disruption of a large fraction of young massive clusters (``infant mortality''). Finally we note that even bound clusters may lose >50% of their initial stellar mass due to rapid gas loss (``infant weight-loss'').

description: We propose a new Movie Map system, with an interface for exploring cities. The system consists of four stages; acquisition, analysis, management, and interaction. In the acquisition stage, omnidirectional videos are taken along streets in target areas. Frames of the video are localized on the map, intersections are detected, and videos are segmented. Turning views at intersections are subsequently generated. By connecting the video segments following the specified movement in an area, we can view the streets better. The interface allows for easy exploration of a target area, and it can show virtual billboards of stores in the view. We conducted user studies to compare our system to the GSV in a scenario where users could freely move and explore to find a landmark. The experiment showed that our system had a better user experience than GSV.

description: Tickle and contagious yawning are predictable behavior affected by social cues and context. Tickle and contagious yawning may be performed abnormally by children with autism or other special needs because they express a variety of social behavior abnormalities. The goal of this study was to develop a questionnaire that can be used to gather descriptive data about tickle and contagious yawning in normally developing children and children with autism or other special needs with the intent of identifying future areas of research in diagnosis and intervention. DeVellis's (2003) principles for scale construction were combined with Dillman's (2000) guidelines for questionnaire construction to guide the questionnaire development process. The questionnaire had low return rates and tickle and contagious yawning items did not form internally consistent scales. Despite these limitations, the questionnaire shows promise for use as a qualitative instrument.

description: Hot work tool steels (HWS) are widely used for high performance components as dies and molds in hot forging processes, where extreme process-related mechanical and thermal loads limit tool life. With the functionalizing and modification of tool surfaces with tailored surfaces, a promising approach is given to provide material flow control resulting in the efficient die filling of cavities while reducing the process forces. In terms of fatigue properties, the influence of surface modifications on surface integrity is insufficiently studied. Therefore, the potential of the machining processes of high-feed milling, micromilling and grinding with regard to the implications on the fatigue strength of components made of HWS (AISI H11) hardened to 50 ± 1 HRC was investigated. For this purpose, the machined surfaces were characterized in terms of surface topography and residual stress state to determine the surface integrity. In order to analyze the resulting fatigue behavior as a result of the machining processes, a rotating bending test was performed. The fracture surfaces were investigated using fractographic analysis to define the initiation area and to identify the source of failure. The investigations showed a significant influence of the machining-induced surface integrity and, in particular, the induced residual stress state on the fatigue properties of components made of HWS.

description: We present Gemini GMOS and Magellan LDSS-3 optical spectroscopy for seven ultracool subdwarf candidates color-selected from the Two Micron All Sky Survey. Five are identified as late-type subdwarfs, including the previously reported sdM9.5 SSSPM 1013-1356 and L subdwarf 2MASS 1626+3925, and a new sdM8.5 2MASS 0142+0523. 2MASS 1640+1231 exhibits spectral features intermediate between a late-type M dwarf and subdwarf, similar to the previously identified high proper motion star SSSPM 1444-2019, and we classify both sources as mild subdwarfs, d/sdM9. 2MASS 1227-0447 is a new ultracool extreme subdwarf, spectral type esdM7.5. Spectral model fits yield metallicities that are consistent with these metallicity classifications. Effective temperatures track with numerical subtype within a metallicity class, although they are not equivalent across metallicity classes. As a first attempt to delineate subtypes in the L subdwarf regime we classify 2MASS 1626+3925 and the previously identified 2MASS 0532+8246 as sdL4 and sdL7, respectively, to reflect their similarity to equivalently classified, solar metallicity L-type field dwarfs over the 7300-9000 A region. We also detail preliminary criteria for distinguishing L subdwarf optical spectra as a roadmap for defining this new spectral class. The strong TiO bands and Ca I and Ti I lines in the spectrum of 2MASS 1626+3925 provide further evidence that condensate formation may be inhibited in metal-deficient L subdwarfs. We conclude with a compendium of currently known, optically classified ultracool subdwarfs.

description: The present research applied a model, modified from existing research on parenting to examine the effects of psychological adjustment, parenting readiness, and environmental protectiveness on the parenting of 54 European Canadian and 32 Aboriginal young mothers. Findings indicated that these factors were predictive of more nurturing and less restrictive parenting in young mothers of both cultures. Environmental protectiveness was the strongest predictor of positive parenting practices, suggesting that intervention programs may have the greatest impact on parenting by inclusion of support groups or teaching coping strategies to relieve stress among mothers. When the cultures were examined separately, none of the variables of interest were predictive of parenting among Aboriginal young mothers. The model applied in the present study has been developed in Western samples and these variables may be less applicable to a Native population. Future research should attempt to identify variables that may be more relevant for Aboriginal families.

description: We have derived new orbits for zeta Aur, 32 Cyg, and 31 Cyg with observations from the TSU Automatic Spectroscopic Telescope and used them to identify non-orbital velocities of the cool supergiant components of these systems. We measure periods in those deviations, identify unexpected long-period changes in the radial velocities, and place upper limits on the rotation of these stars. These radial-velocity variations are not obviously consistent with radial pulsation theory, given what we know about the masses and sizes of the components. Our concurrent photometry detected the non-radial pulsations driven by tides (ellipsoidal variation) in both zeta Aur and 32 Cyg, at a level and phasing roughly consistent with simple theory to first order, although they seem to require moderately large gravity darkening. However, the K component of 32 Cyg must be considerably bigger than expected, or have larger gravity darkening than zeta Aur, to fit its amplitude. However, again there is precious little evidence for the normal radial pulsation of cool stars in our photometry. H-alpha shows some evidence for chromospheric heating by the B component in both zeta Aur and 32 Cyg, and the three stars show among them a meager ~ 2--3 outbursts in their winds of the sort seen occasionally in cool supergiants. We point out two fundamental questions in the interpretation of these stars, (1) whether it is appropriate to model the surface brightness as gravity darkening and (2) whether much of the non-orbital velocity structure may actually represent changes in the convective flows in the stars' atmospheres.

description: A breach of the unprotected electronic data might result in sensitive or confidential information being taken, changed, copied, sent, viewed, or used without authority. This study focuses on having security testing of Rijindael, Rivest Cipher4 and Format Preserving Algorithms in VB.Net Using simulation Comparison Techniques by comparing three (3) encryption algorithms by simulation method to know the most secured algorithm in VB.Net of different minimum and maximum key sizes to determine the security. The study also evaluates the three most common encryption algorithms like Rijandael, Rivest Cipher4 and Format Preserving Encryption Algorithm. A simulation comparison was conducted for those three (3) encryptions algorithms at different settings for each algorithm such as minimum and maximum key size change to know which among those algorithms performs cryptography in the most secured way. Results from simulation analysis showed that Rivest Cipher4 (RC4) is the best algorithm in terms of security among the other compared contenders using the higher key size and lower key size as it maintains an average time for each key size both (Min & Max) followed by Rijandael and format preserving algorithm. This study therefore recommends the adoption of Rivest Cipher4 (RC4) in VB.Net in terms of secured cryptography
DEPRESSIVE SYMPTOMS AND DRUG USE MEDIATED BY BEHAVIOR CHANGE PROCESSES

description: The prevalence and negative influence of depressive symptoms on individuals with substance use disorders, combined with the knowledge that certain behavior change processes are related to abstinence, create the need for research to understand how depressive symptoms, the addictive behavior change process, and drug use outcomes are related.  The purpose of this study was to test a model predicting drug use outcome during a treatment episode in which depressive symptoms were mediated by three behavior change process measures: 1) motivation to change; 2) behavioral coping processes of change; and 3) abstinence self-efficacy. It was hypothesized that greater depressive symptoms would increase drug use both directly and indirectly through the hypothesized decrease in behavior change processes. Seventy-two participants attending outpatient drug use disorder treatment and participating in a larger study named the STOP Project were included in these secondary analyses. Traditional mediation testing with OLS regression and bootstrapped mediation analyses were used to test the model. Results supported the fit of the hypothesized model. The statistical significance testing supported the following relations: greater depressive symptoms increased drug use outcome; greater depressive symptoms decreased behavior change processes; and decreased behavior change processes increased drug use. Treatment site, a covariate in the model, significantly predicted both increased use of behavioral coping processes and decreased drug use post-treatment. These findings support existing literature which highlights the role of depressive symptoms affecting drug use outcomes. The findings further support the existing literature indicating an important role for behavior change processes on drug use outcome. The current findings add to the literature by examining a more complex mediation model of influence that highlights how depressive symptoms impair important behavior change processes. Depressive symptoms demonstrated both direct and indirect effects of increased drug use outcome. Depressive symptoms negatively influenced critical change producing mechanisms by reducing motivation to change, coping behaviors, and confidence, leading to increased drug use. Behavioral coping processes alone mediated the relation between depressive symptoms and drug use. Results are discussed in terms of both clinical and research significance.

description: Despite numerous research efforts, the precise mechanisms of concussion have yet to be fully uncovered. Clinical studies on high-risk populations, such as contact sports athletes, have become more common and give insight on the link between impact severity and brain injury risk through the use of wearable sensors and neurological testing. However, as the number of institutions operating these studies grows, there is a growing need for a platform to share these data to facilitate our understanding of concussion mechanisms and aid in the development of suitable diagnostic tools. To that end, this paper puts forth two contributions: 1) a centralized, open-source platform for storing and sharing head impact data, in collaboration with the Federal Interagency Traumatic Brain Injury Research informatics system (FITBIR), and 2) a deep learning impact detection algorithm (MiGNet) to differentiate between true head impacts and false positives for the previously biomechanically validated instrumented mouthguard sensor (MiG2.0), all of which easily interfaces with FITBIR. We report 96% accuracy using MiGNet, based on a neural network model, improving on previous work based on Support Vector Machines achieving 91% accuracy, on an out of sample dataset of high school and collegiate football head impacts. The integrated MiG2.0 and FITBIR system serve as a collaborative research tool to be disseminated across multiple institutions towards creating a standardized dataset for furthering the knowledge of concussion biomechanics.

Electric and Photoelectric Gates for ion backflow suppression in multi-GEM structures

description: A new approach to suppress ion backflow in multi-GEM structures is suggested. In this approach, the potential difference applied across the gap between two adjacent GEMs is reversed compared to the standard configuration. In such a gap structure, called Electric Gate, a signal transfer from the first to second GEM is presumably provided by the small residual field still existing at small gate voltages and connecting the holes of the two GEMs. On the other hand, ion backflow between the GEMs turned out to be substantially reduced. We also consider another configuration, called Photoelectric Gate, in which in addition to the Electric Gate configuration, a CsI photocathode is deposited on the second GEM. In the Photoelectric Gate, ion backflow through the gap is fully suppressed and the signal transfer through the gap is provided by the photoelectric mechanism due to either avalanche scintillations in the first GEM or proportional scintillations in the electroluminescence gap replacing the first GEM. The idea of the Electric Gate might find applications in the field of TPC detectors and gas photomultipliers. The idea of the Photoelectric Gate is more relevant in the field of two-phase avalanche detectors.

Subjects: intimate partner violence
PTSD
sexual abuse

description: The study intended to investigate the relation between abuse exposure and PTSD symptoms among female partners of men in treatment for relationship abuse.  The association between sexual abuse (both coercion and violence) and PTSD symptoms was of particular interest.  It was hypothesized that the female participants who had experienced any form of sexual abuse would report more PTSD symptoms and have higher rates of probable PTSD diagnosis than the female participants who had not.  Sexual violence was expected to be a unique predictor of PTSD symptoms relative to sexual coercion.  Self-report data (via a structured phone interview) were gathered from 216 female partners of men in treatment for relationship abuse.  The results indicated that the female partners who had experienced sexual abuse reported more PTSD symptoms and had higher rates of probable PTSD, however, these differences may have been accounted for by the presence of psychological abuse.  In contrast to what was hypothesized, sexual coercion was a unique predictor of PTSD symptoms relative to sexual violence.  The findings from the study suggest that many female partners report sexual abuse exposure and that this is an important area for assessment and treatment.  Overall, psychological abuse appeared to be an important variable in nearly all analyses, making the case for further consideration of its influence on PTSD symptoms.

Correlates of Absenteeism and Presenteeism in Temporomandibular Joint Disorder: The effects of pain severity and pain catastrophizing on work productivity

Subjects: Coping

Work Productivity

description: Severe pain and poor pain-related coping have been shown to negatively impact daily functioning. However, associations between these factors and lost work productivity in temporomandibular joint disorder (TMD) have received little attention. The current study investigated the effects of pain severity and pain catastrophizing on absenteeism (physical absence from work) and presenteeism (on-the-job lost work productivity) in a full-time, working for pay TMD sample. Pain severity, but not catastrophizing, was significantly associated with reported absenteeism. Both pain severity and catastrophizing significantly predicted presenteeism after controlling for the effects of race and depressive symptoms. The interaction effect of these factors was non-significant in predicting presenteeism. Helplessness significantly contributed to reported presenteeism accounting for the effects of the other pain catastrophizing subscales (rumination and magnification). Further research investigating the impact of negative affectivity (i.e. depressive symptoms) may further elucidate the associations of pain severity and pain-related coping with lost work productivity.

description: We report on the observation of a Tc ~0.9 K superconductivity at the interface between LaAlO3 film and the 5d transition-metal oxide KTaO3(110) single crystal. The interface shows a large anisotropy of the upper critical field, and its superconducting transition is consistent with a Berezinskii-Kosterlitz-Thouless transition. Both facts suggest that the superconductivity is two-dimensional (2D) in nature. The carrier density measured at 5 K is ~7 time 10^13 cm-2. The superconducting layer thickness and coherence length are estimated to be ~8 and ~30 nm, respectively. Our result provides a new platform for the study of 2D superconductivity at oxide interfaces.

Coordinated Interpersonal Timing in Marital Interactions

Temporal Patterning

description: Previous research has recommended that temporal patterning be investigated in marital interactions. This project examined Coordinated Interpersonal Timing (CIT), which is a means of assessing the temporal patterns of speech, in marital interactions. Associations were explored between CIT and general relationship satisfaction, as well as between CIT and behavioral coding of the same interaction utilizing Rapid Marital Interaction Coding System (RMICS).  CIT considers an individual's sounds (vocalizations), silences between the vocalizations of the same speaker (pauses), and silences between the turns of one speaker and the turns of the other speaker, which are attributed to the speaker who initiated the pause (switching pauses).  These various states are assessed free of their intonation and verbal content.  CIT utilizes these speech parameters to evaluate their coordination in the rhythms of dialogue. In this sample of 19 married couples (N = 38, with 19 men and 19 women), CIT uniquely accounted for 39% of the variance in relationship adjustment. Wife's Switching Pause CIT was inversely related to husband's satisfaction. Husband's Pause and Switching Pause CIT were both positively related to wife's satisfaction, and husband's Vocalization CIT was inversely related to wife's satisfaction. This research highlights important contributions and necessitates additional investigation into temporal assessment of marital interactions. Given that patterns within communication are considered clinically diagnostic, it is the case improved that understanding and application of this approach to couples' interactions will provide cost-effective, descriptive data on marital interactions.

description: Photometric observations of asteroid (596) Scheila were obtained during and after its 2010 outburst. The estimated radius of the body (spherical approximation of the asteroidal body) was 51.2 km and 50.67 km for different methods. The ejected dust mass from the asteroid ranged from 2.5*10e7 to 3.4*10^7 kg for different methods. An impact mechanism for triggering Scheila's activity is discussed. A few days before the impact, Scheila passed through the corridors of two potential cometary streams.

description: We investigate the charging energy level statistics of disordered interacting electrons in quantum dots by numerical calculations using the Hartree approximation. The aim is to obtain a global picture of the statistics as a function of disorder and interaction strengths. We find Poisson statistics at very strong disorder, Wigner- Dyson statistics for weak disorder and interactions, and a Gaussian intermediate regime. These regimes are as expected from previous studies and fundamental considerations, but we also find interesting and rather broad crossover regimes. In particular, intermediate between the Gaussian and Poisson regimes we find a two-sided exponential distribution for the energy level spacings. In comparing with experiment, we find that this distribution may be realized in some quantum dots.
