A Surrogate Safety Assessment of Scrambled Phase Intersections
Creators: Ghaneei, Zakiye
Publisher: name: University of Alberta Library
Year: 2023

Since traffic safety is a significant concern for policymakers and researchers, multiple studies have been conducted to address this issue and create a safer environment for all road users, especially pedestrians. One of the approaches to achieving this is installing scramble phases at intersections with high volumes of vulnerable road users. This research evaluated the safety impact of installing the scramble phase at the two intersections in Edmonton, Canada, over three periods. The first observation was made before the installation of the scramble phase, followed by observations immediately after the installation, and finally, after six months of installation. The research utilized two approaches to evaluate the safety impact of the scramble phase installation. The first approach was to observe the frequency of right-turn-on-red violations. The second approach involved investigating the frequency of serious conflicts before and after the installation using three safety indicators, namely, Time to Collision (TTC), Time Difference to Point of Intersection (TDPI), and Distance between Stop Position and Pedestrian (DSPP). The number of breaches before and after the installation was counted manually to evaluate the frequency of right-turn-on-red violations. The results showed a decrease in the total number of right-turn-on-red violations after the implementation during the six months. However, there was a slight increase in violations during the pedestrian phase at one intersection after six months. The research used conflict detection and automatic indicator calculations to assess the frequency of serious conflicts. The results showed a 65% decrease in all three safety indicators immediately after the installation of the scramble phase at the Calgary trail intersection. Furthermore, after six months, there were no incidents of DSPP and TDPI at this intersection. At one of the study intersections, there was also a reduction in serious conflicts, although it was less than 50% immediately after the installation. However, this improvement increased to 80% for all indicators after six months. Reduced severe conflicts and total right-turn-on-red violations indicate that installing the scramble phase positively impacted intersection safety.

description: We present a model of classical hard-core dimers on the square lattice that contains an Ising nematic phase in its phase diagram. We consider a model with an attractive interaction for parallel dimers on a given plaquette of the square lattice and an attractive interaction for neighboring parallel dimers on the same row ({\it viz} column) of the lattice. By extensive Monte carlo simulations we find that with a finite density of holes the phase diagram has, with rising temperatures, a columnar crystalline phase, an Ising nematic liquid phase and a disordered fluid phase, separated by Ising continuous phase transitions. We present strong evidence for the Ising universality class of both transitions. The Ising nematic phase can be interpreted as either an intermediate classical thermodynamic phase (possibly of a strongly correlated antiferromagnet) or as a phase of a 2D quantum dimer model using the Rokhsar-Kivelson construction of exactly solvable quantum Hamiltonians.

Hardware Accelerators for Deep Neural Networks
Creators: Machupalli, Raju
Publisher: name: University of Alberta Library
Year: 2023

Deep Neural Networks (DNNs) have recently evolved as the state-of-the-art method for machine learning applications such as object detection, face recognition, and image classification. However, a DNN typically has high computational complexity, and specialized hardware accelerators would be helpful to obtain real-time performance.

Over the last decade, many accelerators have been proposed in the literature for DNN models. This thesis presents a comprehensive review of the existing DNN accelerators. The accelerators were classified into four categories: ALU, Dataflow, Sparsity, and Hybrid, based on the optimization techniques used. The classification provides a good starting point to identify significant areas where an accelerator can be further optimized for better throughput, latency, and energy performance.

In this thesis, we also explored the bit-precision requirement of the MAC units for DNN implementation. A DNN has two modes of operations: Training and Inference. It is generally known that the inference can be done using lower-precision MAC units, but the training requires higher-precision MAC units. The lower-precision MAC units consume less energy which may be desirable for low-power applications. We propose an iterative MAC model where the inference will be done using low-precision MAC in a single pass, and the training will be done with the same low-precision MAC using multiple passes (to achieve higher bit precision). The proposed model, during training, determines the number of iterations on the fly by checking the error magnitude. Experimental results, with LeNet-300-100 model implemented using the iterative MAC, show a satisfactory performance for digit classification.
Popular music in post-revolutionary Iran: concepts, definitions, and restrictions
Creators: Mofidi Tehrani, Ardavan
Publisher: name: University of Alberta Library
Year: 2023

Despite the restrictions imposed on Iran's music atmosphere in the years after the 1979 Islamic revolution, different music genres survived and overcame these restrictions. Westernized popular music (musiqi-e pāp) and its presence in public space has been one of the controversial topics among Islamic theologians after the revolution, ranging from complete outlawing to freedom of all its forms. In the first decades following the revolution, the government marginalized Westernized popular music more than any other genre by trying to eradicate everything that had a sign of the Pahlavi Modernization-Westernization era. After the reforms of 1998 and fundamental changes in the country's policies in various fields, musiqi-e pāp overcame the restrictions and their intensity. After a long absence, women were allowed to appear at music venues as musicians, and young musicians were allowed to perform and get authorization to publish their music officially. However, these restrictions took many forms and were manifested in banning women's solo singing and dancing and the need for authorizations with complicated procedures for music production.

Based on analyzing written work around Iran's popular music and autoethnographic research, this thesis examines how the dynamics of restriction changed over the years by changing state policies and the development of technological advancements such as the internet and how both the Islamic government and the people made compromises over time. Combining the concepts discussed in scholarly works about Iranian popular music with an autoethnographic perspective will help redefine the concepts as an insider and determine their place and importance in the post-revolutionary popular music scene.

description: We study the properties of giant clumps and their radial gradients in high-$z$ disc galaxies using AMR cosmological simulations. Our sample consists of 770 snapshots in the redshift range $z=4-1$ from 29 galaxies that at $z=2$ span the stellar mass range $(0.2-3)\times 10^{11}M_{\odot}$. Extended gas discs exist in 83% of the snapshots. Clumps are identified by gas density in 3D and their stellar and dark matter components are considered thereafter. While most of the overdensities are diffuse and elongated, 91% of their mass and 83% of their star-fromation rate (SFR) are in compact round clumps. Nearly all galaxies have a central, massive bulge clump, while 70% of the discs show off-center clumps, 3-4 per galaxy. The fraction of clumpy discs peaks at intermediate disc masses. Clumps are divided based on dark-matter content into $\textit{in-situ}$ and $\textit{ex-situ}$, originating from violent disc instability (VDI) and minor mergers respectively. 60% of the discs are in a VDI phase showing off-center $\textit{in-situ}$ clumps, which contribute 1-7% of the disc mass and 5-45% of its SFR. The $\textit{in-situ}$ clumps constitute 75% of the off-center clumps in terms of number and SFR but only half the mass, each clump containing on average 1% of the disc mass and 6% of its SFR. They have young stellar ages, $100-400 {\rm Myr}$, and high specific SFR (sSFR), $1-10 {\rm Gyr}^{-1}$. They exhibit gradients resulting from inward clump migration, where the inner clumps are somewhat more massive and older, with lower gas fraction and sSFR and higher metallicity. Similar observed gradients indicate that clumps survive outflows. The \exsitu clumps have stellar ages $0.5-3 {\rm Gyr}$ and sSFR $\sim 0.1-2 {\rm Gyr}^{-1}$, and they exhibit weaker gradients. Massive clumps of old stars at large radii are likely \exsitu mergers, though half of them share the disc rotation.

Learning effective machine learning models for clinical applications in psychiatry
Creators: Sawalha, Jeffrey
Publisher: name: University of Alberta Library
Year: 2023

This is a comprehensive examination of the diagnostic landscape in psychiatry and the role precision psychiatry might play in redefining how we classify illnesses. This thesis delves into three areas that currently exist in psychiatry today and is divided into five chapters. The first and second chapters review the literature and clinical space of AI and psychiatry. The last three chapters consist of academic articles that explore the use of AI in the three problematic areas of psychiatry.The third chapter involves the early stage detection of Bipolar Disorder (Type 1) using cognitive assessments. Identifying cognitive dysfunction in the early stages of Bipolar Disorder (BD) can allow for early intervention. Previous studies have shown a strong correlation between cognitive dysfunction and the number of manic episodes. The objective of this study was to apply machine learning (ML) techniques on a battery of cognitive tests to identify first-episode BD patients (FE-BD). Specifically, we wanted to know if we could make generalized predictions about the various stages of BD using cognitive tests.The fourth chapter examines childhood anxiety and produces a learned model that can detect dysfunction in the brains of children while they examine emotional facial expressions. Childhood anxiety is a difficult disorder to diagnose due to validity controversies and the conflation of normal developmental-behavioral patterns with anxiety symptoms. Our study not only seeks to train a model that can distinguish anxious from non-anxious children, but also to discover neural markers related to this diagnosis.Lastly, the fifth chapter utilizes natural language processing to detect the presence of post-traumatic stress disorder (PTSD). Specifically, we utilize sentiment analysis, a sub area of natural language processing (NLP), to extract emotional content from text information. In our study, we train an ML model on text data, which is part of the Audio/Visual Emotion Challenge and Workshop (AVEC-19) corpus, to identify individuals with PTSD using sentiment analysis from semi-structured interviews. We sought to understand the emotional spectrum of language and compare our findings with the ongoing literature.Together, each of these studies illustrate how ML can be used to augment clinical decision-making surrounding the underlying conditions of individuals who may suffer from these illnesses. In doing so, we provide a conceptual review of the current barriers that exist in precision psychiatry today. Our hope is to provide the reader with a foundation of how ML can be used in psychiatry, while also highlighting some of the current barriers that hold back this field today. This comes in the form of a conceptual review (Chapter 2) and sets the landscape for the three published articles included.

description: By analyzing oral reading, we can examine the ability to read and many elements of reading comprehension, which play an important role in the diagnosis of reading disorders and development of reading techniques. In the present study, we analyze the changes in oral reading in schoolchildren between 4th and 5th grade. In our previous research, the correlations between reading time, number of errors, frequency of self-repairs, and frequency and average duration of eye-movements were already examined in recordings of the same children. In the present study, the main question is the following: What eye-movements occur during error-repairs? Students of average ability from an average primary school in the capital participated in the study. The experiment was performed twice, one year apart: the children were in 4th grade at the time of the first measurement and in 5th grade at the time of the second measurement. The results of oral reading of 10 children (5 boys and 5 girls) are presented in the study, for whom the loss of data was less than 10% in the recordings of the eye-movements. The children’s task was to read aloud the same text from the monitor, in both measurements. Recordings and analysis were performed in both cases with the same instrument (Tobii X120) and software. Speech analysis and evaluation of eye-movements were performed with Praat and ELAN software. Results show that although the speech rate of oral reading accelerated to 5th grade, the frequency of errors and the time required for self-repairs did not change or increased. However, there were differences between the two measurements in eye-movements during error-repairs. The results draw attention to the fact that reading development would be needed even in the 5th grade.

description: This study uses a content analysis of adult fiction books from realistic genres set in current times to explore how library patron diversity is portrayed in textual descriptions in order to better understand the messages that patrons from marginalized groups receive from books that feature libraries and library patrons and whether they are finding themselves depicted or excluded. This study analyzes eight books which have been coded for key terms that convey character traits pertaining to diversity, especially visible traits, and analyzed to determine how many books include diverse library patron characters. This study could shed light on what messages libraries, authors, and publishers are unknowingly sending to the patrons about who belongs in the library.

Kísérletet tesz a jelenség hezitációs és diskurzusszervező funkciójának elkülönítésére, utóbbit az öö-nek a társalgásban elfoglalt strukturális pozícióihoz köti. Induktív kvalitatív elemzéssel az öö valamennyi előfordulását megvizsgálja, és öt jellegzetes szerkezeti pozíciót állapít meg, amelyekben az öö használatával a beszélők befolyásolhatják a beszélőváltás működését, illetve kifejezhetik a beszélőváltás szabályaihoz való attitűdjüket. Ezek a pozíciók lehetnek váltásreleváns helyen és váltásreleváns hely előtt is. Az elemzések azt mutatják, hogy az öö mindhárom beszélőváltási szabály (vö. Sacks et al., 1974) működésekor szerepet kaphat. Azok a diskurzusjelölők, amelyek a megnyilatkozás szintaktikai szerkezetétől függetlenek, lehetnek nemlexikálisak is, és érinthetik a társalgás szekvenciális szerkezetét (Fischer, 2006, p. 9). Ide tartoznak azok a diskurzusjelölők, amelyek a beszélőváltási rendszer szabályozásában vesznek részt. Ez alapján azok az öö-k, amelyek befolyásolják a beszélőváltás működését, illetve a beszélőnek a beszélőváltás szabályaihoz való valamely attitűdjét fejezik ki, tekinthetők diskurzusjelölőnek.

description: Recommender systems enable users to navigate in the sea of mass information. TikTok, one of the fastest-growing short-video social platforms, offers countless videos that are curated according to users’ interests by the recommendation engine of For You page. However, the bias in recommendation brought on by the nature of the algorithm impact user experience in a number of aspects. In order to identify the mechanism and bias in the TikTok recommendation system, this study conducts two user-centric methods of data collection: semi-structured interview and walkthrough evaluation. This study aims to analyze the algorithm and bias of recommendation while exploring the user experience of using TikTok and how different types of bias affect their experience. Upon the analysis of data, the findings indicate that popularity bias and exposure bias exist in the system, and the user experience is influenced due to the bias.

SWAN: A Static Analysis Framework for Swift
Creators: Tiganov, Daniil
Publisher: name: University of Alberta Library
Year: 2023

Swift is an open-source programming language and Apple’s recommended choice for app development. Given the global widespread use of Apple devices, the ability to analyze Swift programs has significant impact on millions of users. Although static analysis frameworks exist for various computing platforms, there is a lack of comparable tools for Swift. Existing Swift static analysis tools are either incomplete, use dynamic analysis, or are otherwise not suitable for deeper analyses of Swift programs such as taint tracking. Moreover, other existing tools for Swift only help enforce code styles and best practices.

In this thesis, we present SWAN, an open-source and configurable framework that allows robust program analyses of Swift programs. SWAN features a suite of call-graph construction algorithms, support for modelling black-box functions using its own internal representation, and can track dataflow through libraries. The framework is also capable of traditional taint analysis, typestate analysis, and detecting security vulnerabilities, such as cryptographic API misuses. We demonstrate the framework’s robustness by evaluating its core framework runtime performance, call-graph construction precision and performance, and ability to find cryptographic API misuses in real Swift applications. For most of our benchmarks, SWAN parses, translates, and prepares the program for analysis in under 5 seconds and builds a precise call-graph in less than 13 seconds. SWAN also finds 43 real cryptographic API misuses across 13 applications that we tested.

description: Extending our previous work (Rosu, Mancas, Chen, Ann.Phys. 343 (2014) 87-102), we define supersymmetric partner potentials through a particular Riccati solution of the form F(x)=(x-c)^2-1, where c is a real shift parameter, and work out the quartic double-well family of one-parameter isospectral potentials obtained by using the corresponding general Riccati solution. For these parametric double well potentials, we study how the localization properties of the two wells depend on the parameter of the potentials for various values of the shifting parameter. We also consider the supersymmetric parametric family of the first double-well potential in the Razavy chain of double well potentials corresponding to F(x)=(1/2)sinh 2x-2(1+sqrt 2)sinh 2x/[(1+sqrt 2) cosh 2x+1], both unshifted and shifted, to test and compare the localization properties

description: Az anyai dajkanyelvet (infant-directed speech - IDS) az akusztikai sajátosságai mellett lexikai és szintaktikai egyszerűsítés is jellemzi, amelyben eltér a felnőttekhez irányított beszédtől (adult-directed speech - ADS). Ezek a lexikai és szintaktikai jellemzők a magyarban még nem igen kutatottak. A nemzetközi szakirodalomban eltérő nézetek találni arról, hogyan válik a dajkanyelv a gyermek életkora szerint komplexebbé, ez a folyamat lineáris vagy nem lineáris. Feltételezésünk szerint a gyermek második életévében található egy komplexitási "padló". Kutatásunkban a beszédbőséget (megnyilatkozások száma), a lexikai tulajdonságokat (type-token arány, ige-főnév arány, szószám) és szintaktikai tulajdonságokat vizsgálatunk az anyai dajkanyelvben meseolvasási szituációban egy longitudinális vizsgálat keretein belül. 22 anya-baba páros vett részt a kuttásban, a baba 1 napos, 6 hónapos és 18 hónapos korában. Minden alkalommal egy IDS és egy ADS felvételt készítettünk. A gyermek 18 hónapos korában találtuk a legnagyobb mértékű szintaktikai és lexikai egyszerűsődést. Eben az életkorban az édesanyák a mesét szignfikánsan hosszabban mesélték el, miközben kisebb igei szókincset és több ismétlést alkalmaztak. A megnyilatkozásaik szignifikánsan rövidebbek voltak. Tehát a szövegeket nagyon beszédbőség jellemezte, azonban kisebb megnyilatkozási egységekben. Az eredményeink a nem lineáris komplexitási hipotézist támogatják.

description: We introduce stamp chains. A stamp chain is a finite integer sequence that is both an addition chain and an additive 2-basis, i.e., a solution to the postage stamp problem. We provide a simple method for converting known postage stamp solutions of length k into stamp chains of length k+1. Using stamp chains, we construct an algorithm that computes u(x^i) for i=1,...,n in less than n-1 multiplications, if u is a function that can be computed at zero cost, and if there exists another zero-cost function v such that v(a,b) = u(ab). This can substantially reduce the computational cost of repeated multiplication, as illustrated by application examples related to matrix multiplication and data clustering using subset convolution. In addition, we report the extremal postage stamp solutions of length k=24.

Az eredmények bemenetét képezhetik a vizuális beszédszintézis számos elemének (pl. beszélő fej, amely a siket és nagyothalló gyermekek tanítását segíti). A méréssel kapott jellemzők révén kiterjeszthetők a már meglévő adathalmazok, és finomítható az artikuláció korábban alkalmazott dinamikus modellje. Ez a törekvés két fő adattípus egyidejű értelmezését kívánja meg: 1.) A száj alakjához kapcsolódó információk, melyek viszonylag egyszerűen vizsgálhatók normál kamerafelvételek segítségével. 2.) A nyelv pozícióját leíró paraméterek, melyek kinyerése orvosi képalkotó berendezések alkalmazását és az azokból származó jelek feldolgozását igényli. A hangok képzési helye a nyelv alakjának és helyzetének megadásával egyértelműen jellemezhető. A nyelv pozícióját magánhangzók esetében a nyelv súlypontjának, mássalhangzók esetében pedig a nyelv szájpadlástól mért távolságának segítségével becsüljük. Elemzéseinkhez dinamikus MRI-felvételeket használunk, és a hozzájuk tartozó nyelvkontúrokat automatikus algoritmusok futtatásával határozzuk meg. Analízisünk nyomán előáll egy olyan adathalmaz, amely statikusan definiálja a vizuális beszédszintézisben fontos szerepet játszó artikulációs kulcskereteket (tisztán az adott beszédhanghoz tartozó nyelvállást rögzítő, a hangátmenetek sajátságait nélkülöző keretek). Eredményeinket a már létező, magyar transzparens beszélő fej fejlesztésére alkalmazzuk egy a dinamikus paraméterek részletesebb felderítésére irányuló pontosabb modell kialakításával. Ez magában foglalja az artikulációs jellemzők időbeli követését, illetve a kulcskeretek közötti interpoláció megvalósítását, ami a koartikulációs hatások leírását szolgálja.

description: Predictions and discoveries of new phases of superfluid $^3$He in confined geometries, as well as novel topological excitations confined to surfaces and edges of near a bounding surface of $^3$He, are driving the fields of superfluid $^3$He infused into porous media, as well as the fabrication of sub-micron to nano-scale devices for controlled studies of quantum fluids. In this report we consider superfluid $^3$He confined in a periodic geometry, specifically a two-dimensional lattice of square, sub-micron-scale boundaries ("posts") with translational invariance in the third dimension. The equilibrium phase(s) are inhomogeneous and depend on the microscopic boundary conditions imposed by a periodic array of posts. We present results for the order parameter and phase diagram based on strong pair breaking at the boundaries. The ordered phases are obtained by numerically minimizing the Ginzburg-Landau free energy functional. We report results for the weak-coupling limit, appropriate at ambient pressure, as a function of temperature T, lattice spacing L, and post edge dimension, $d$. For all $d$ in which a superfluid transition occurs, we find a transition from the normal state to a periodic, inhomogeneous "polar" phase with $T_{c_1} < T_c$ for bulk superfluid $^3$He. For fixed lattice spacing, L, there is a critical post dimension, d_c, above which only the periodic polar phase is stable. For $d < d_c$ we find a second, low-temperature phase onsetting at $T_{c_2} < T_{c_1}$ from the polar phase to a periodic "B-like" phase. The low temperature phase is inhomogeneous, anisotropic and preserves time-reversal symmetry, but unlike the bulk B-phase has only $D_{4h}$ point symmetry.

The Impact Of Colonization by Multi Drug Resistant Bacteria on Graft Survival, Risk of Infection, and Mortality in Recipients of Solid Organ Transplant: Systematic Review and Meta-analysis
Creators: Almohaya, Abdulellah
Publisher: name: University of Alberta Library

Background: Colonization with multi-drug resistant bacteria (MDR) in solid organ transplant (SOT) recipients

increases the risk of post-transplant bacterial infection. The impact of MDR colonization on graft survival and

mortality is not well established.

Methods: We searched PROSPERO, OVID Medline, Ovid EMBASE, Wiley Cochrane Library, ProQuest

dissertations and Theses Global and SCOPUS, from inception until March 20, 2023. Cohort and case control studies with adult SOT colonized with Methicillin resistant Staphylococcus aureus (MRSA), Vancomycin- resistant Enterococci (VRE), Extended-spectrum beta-lactamase (ESBL), AmpC producing bacteria, carbapenem resistant Enterobacteriaceae (CRE), or MDR Pseudomonas were included. Pairs of reviewers screened abstracts and full studies for inclusion and extracted data independently. We used RevMan to conduct a meta-analysis using random-effects models to calculate the pooled odds ratio (OR) and 95% confidence interval (CI) for mortality, infection, and graft loss. We assessed statistical heterogeneity using I 2 statistic, bias assessment with Newcastle-Ottawa Scale (NOS) and rated the certainty of evidence using the Grading of Recommendations Assessment, Development, and Evaluation methodology. The protocol is registered with (CRD42022290011).

Results: A meta-analysis of 33 cohort and 6 case control studies included 4077 SOT recipients with MDR colonization. Liver transplant (25) and VRE colonization (14) studies constituted the most common organ and MDR bacterium, respectively. Death (OR= 2.35, 95%CI 1.63-3.38) and infection within one year (OR 10.74, 95%CI 7.56-12.26) were significantly higher among MDR colonized transplant recipients across all types of transplant (p<0.001 and I2= 58%). MDR colonization did not increase the risk of graft loss (OR=1.17, 95%CI 0.81-1.69; p=0.41, I2= 0%).

Conclusion: We identified low certainty of evidence that MDR colonization in SOT increases the odds of infection and death but not graft loss. Actions for preventing of colonization in transplant candidates are warranted.
Direct and Indirect Utilization of Synthetic and Natural Polymers for Biosensing

Polymers are molecules consisting of many repeating subunits, also known as macromolecules. Both natural and synthetic polymers have been used widely for textiles, food packaging, tissue engineering, water treatment, sensing, and drug delivery. Among the variety of applications, polymer-based sensors are of particular interest. For polymer-based sensing, polymers often serve as scaffolds for other functionalities, such as nanoparticles and fluorophores. Moreover, stimuli-responsive polymers can change their physical and chemical properties in response to small environmental fluctuations, which are often employed in sensing applications. The use of polymers can enhance the sensor performance by improving water solubility, biocompatibility, and stability of the sensor. In addition, polymers can be modified easily with various target recognition moieties to interact with myriad analytes. Therefore, polymer-based sensors have received increasing attention.

This thesis focuses on the development of polymer-based sensors; the systems either use polymers to facilitate the direct or indirect detection of analytes. Chapter 1 gives a brief introduction of natural and synthetic polymers as well as their applications. Chapter 2 describes the use of bovine serum albumin-protected gold nanoclusters (BSAGNCs) for the detection of both anti-SARS-CoV-2 RBD specific IgG antibodies and the SARS-CoV-2 virus, based on cysteamine etching-induced fluorescence quenching of BSAGNCs. Chapter 3 focuses on the development of a responsive poly(N-isopropylacrylamide-co-acrylic acid) (pNIPAm co-AAc) etalons-based immunoassay for the detection of mouse IgG. Mouse IgG captured on the etalon surface from solution was quantified, using an HRP-conjugated secondary antibody. HRP catalyzed the oxidation of 4 chloro-1-naphthol (4CN) to form insoluble 4-chloro-1-naphthon (4CNP), resulting in a concentration change of 4CN in solution. The etalon was able to detect the 4CN concentration, which allows the quantitation of mouse IgG. In Chapter 4, we synthesized a fluorescent microgel, poly(N-isopropylacrylamide-co-Nile blue) (pNIPAm-co-NB), which is responsive to temperature, salt, and polyamine. Chapter 5 gives a brief conclusion and future outlook for the previous chapters. Finally, Appendix A includes a study of a fluorescent product generated from Cu2+ assisted L ascorbic acid oxidation. This study shows some potential applications of the fluorescent product, such as oxygen, iron ion, and pH sensor.

description: We consider time-reversal-symmetric two-channel semiconducting quantum wires proximity coupled to an s-wave superconductor. We analyze the requirements for a nontrivial topological phase and find that necessary conditions are 1) the determinant of the pairing matrix in channel space must be negative, 2) inversion symmetry must be broken, and 3) the two channels must have different spin-orbit couplings. The first condition can be implemented in semiconducting nanowire systems where interactions suppress intra-channel pairing, while the inversion symmetry can be broken by tuning the chemical potentials of the channels. For the case of collinear spin-orbit directions, we find a general expression for the topological invariant by block diagonalization into two blocks with chiral symmetry only. By projection to the low-energy sector, we solve for the zero modes explicitly and study the details of the gap closing, which in the general case happens at finite momenta.

description: The end-to-end deep neural network based speech recognition approach is increasingly popular due to its fully data driven nature - no language-specific knowledge is needed beyond the transcribed speech data. However, most of the end-to-end speech recognition experiments are performed on read (planned) speech and no Hungarian language results are available for the Speech Community. In this paper, we make the first attempt to train and evaluate a Hungarian speech recognition system based on the studio-quality Hungarian BEA (Spoken Language Speech Database) in an end-to-end neural manner. We present the challenge of recognising spontaneous speech: even without any significant background noise, the word error rate on spontaneous speech is an order of magnitude higher than in the case of planned speech - both recorded with the same speakers in the same environment. This emphasises the need for more thorough studies of spontaneous speech and possibly for more data.
GGNMOS for Electrostatic Discharge (ESD) Protection: Study on Device Structure and Circuit Model
Creators: Then, Ian Z.
Publisher: name: University of Alberta Library
Year: 2023

Electrostatic discharge (ESD) is a major reliability concern in the integrated circuit (IC) industry. Improving our understanding of ESD behavior and characteristics in semiconductor devices is crucial in the development of better ESD protection devices. Technology computer aided design (TCAD) tools can be leveraged for this, enabling users to perform comprehensive electro-thermal simulations to determine the ESD robustness of a device.

In this thesis, Synopsys Sentaurus TCAD is used to perform a systematic structural parameter variation on a 0.18μm multi-finger gate-grounded N-channel MOSFET (GGNMOS). 2.5D mixed-mode simulation is conducted. In addition to widely explored structural parameters, the effects of certain structural parameters that are rarely investigated such as the guard ring length and shallow trench isolation (STI) length are also studied in this thesis. In TCAD simulation, a quasi-DC ESD current ramp is used with a current ramp rate of 3A/μs to generate the ESD stress, in place of a commonly used transmission line pulse (TLP), with comparable results. This reduced the amount of time needed to simulate the resulting ESD current-voltage (I-V) curve from hours to minutes. Verification of the simulation workbench is carried out by varying and simulating the effects of parameters like finger number, finger width, and drain- and source-contact-to-gate lengths (DCG and SCG).

When investigating the effect of the guard ring length influence on the ESD performance of a multi-finger GGNMOS, we found that there was no influence on  Vh, Vt2, It2, and Ron. Ih data had large variance due to non-uniform triggering, so results were inconclusive. The guard ring length has a slight influence on Vt1 and It1, but further investigation is needed to understand their relationship. Investigating the STI length influence on multi-finger GGNMOS showed that Vt1 and Vh decreased with increased STI length. Further investigation is needed to understand the dependence of Vh  on the STI length. However, Vt1 dependence on STI length can be explained with substrate resistance, Rsub. An increase in STI length results in an increased distance between finger and substrate terminal, increasing the Rsub, and enables earlier triggering of the parasitic BJT, thereby reducing Vt1.

Taking a quantitative approach,  the relationship between Vt1 and STI length is investigated using a proposed circuit model-based method. In this work, circuit simulation is conducted using an equivalent GGNMOS compact model in LTSPICE. The STI length is represented by a Rsub. By fitting the circuit I-V curves to the TCAD I-V curves, extracted Rsub values for various GGNMOS devices were obtained. The findings proved that numerically, when STI length increases (represented by an Rsub increasing), then Vt1 decreases.

description: This paper studies the switching of trading strategies and its effect on the market volatility in a continuous double auction market. We describe the behavior when some uninformed agents, who we call switchers, decide whether or not to pay for information before they trade. By paying for the information they behave as informed traders. First we verify that our model is able to reproduce some of the stylized facts in real financial markets. Next we consider the relationship between switching and the market volatility under different structures of investors. We find that there exists a positive relationship between the market volatility and the percentage of switchers. We therefore conclude that the switchers are a destabilizing factor in the market. However, for a given fixed percentage of switchers, the proportion of switchers that decide to buy information at a given moment of time is negatively related to the current market volatility. In other words, if more agents pay for information to know the fundamental value at some time, the market volatility will be lower. This is because the market price is closer to the fundamental value due to information diffusion between switchers.
