Effects of ground motion duration on the seismic performance and collapse capacity of timber structures

description: This thesis describes the performance of timber structures under long duration earthquakes. The primary objective of this study is to quantify the effects of long duration ground shaking on wood structures compared to short duration shaking. The investigation is confined to conventional low-rise and modern mid-rise woodframe buildings. Full scale models of the benchmark structures used for this investigation were also constructed and tested on shake tables. Three-dimensional numerical models of the structures were developed using the Timber3D program and validated with the shake table test data. To isolate the effects of duration, two sets of short and long duration records that had approximately the same response spectra were used for nonlinear dynamic analyses of the model structures. Their collapse capacity was evaluated using fragility curves developed by incremental dynamic analysis. The results showed the collapse rate increased under long duration shaking due to a large number of inelastic cycles and higher cumulative energy demands that timber structures experienced compare with the short duration motions. The reduction in median collapse capacity for the low-rise wood structure with engineered oriented strand board (OSB) sheathing and stucco was 26%, for the same structure but without stucco was 29%, and for structure with horizontal board sheathings was 61%, respectively. The reduction in median collapse capacity for the mid-rise woodframe structure was 18%. These results suggest that current design practice based on the response spectra analysis may not adequately characterize the potential collapse of timber structures. This study highlights the need to include ground motion duration effects into current seismic design and assessment provisions.

description: Mieczysław Wolfke, a Polish physicist born in 1883 in Łask, from childhood showed an extraordinary interest in science and technology as well as a predisposition to unprecedented imagination and intuition. At the age of 13, he developed the idea of a jet propulsion, and four years later he patented a wire-less telectroscope - a prototype of wireless television based on a modified Nipkov disk. During his doctoral dissertation on Ernst Abbe's theory, he mastered the theory of diffraction, which in 1920 allowed him to postulate the possibility of two-stage imaging by recording the spatial spectrum of an image and its reconstruction using radiation of a different wavelength. His work, crucial to the holographic technique, preceded the independently made discovery of Dennis Gabor, who was awarded the 1971 Nobel Prize for it, by more than 20 years. In the years 1913-1921 Wolfke participated in the quantum theory interpretations undertaken in Zurich (Albert Einstein, Max von Laue, Erwin Schroedinger), postulating that the energy modes of the black body cavity should be assigned the interpretation of multiple photons (light molecules). In 1924-1927 he collaborated with the Leiden Laboratory, where he proposed a method of solidifying helium under pressure and discovered liquid helium II, the world's first quantum liquid. Throughout his life, Wolfke dealt with problems close to the achievements awarded with the Nobel Prize. Unfortunately, he himself did not live to see such a distinction, dying suddenly in 1947.

description: We have used Molecular Beam Epitaxy (MBE)-based delta doping technology to demonstrate near 100% internal quantum efficiency (QE) on silicon electron-multiplied Charge Coupled Devices (EMCCDs) for single photon counting detection applications. Furthermore, we have used precision techniques for depositing antireflection (AR) coatings by employing Atomic Layer Deposition (ALD) and demonstrated over 50% external QE in the far and near-ultraviolet in megapixel arrays. We have demonstrated that other device parameters such as dark current are unchanged after these processes. In this paper, we report on these results and briefly discuss the techniques and processes employed.

description: We present an analytic technique for evaluating single cuts for one-loop integrands, where exactly one propagator is taken to be on shell. Our method extends the double-cut integration formalism of one-loop amplitudes to the single-cut case. We argue that single cuts give meaningful information about amplitudes when taken at the integrand level. We discuss applications to the computation of tadpole coefficients.

description: Searches for a heavy Standard Model Higgs boson focus on the 'gold plated mode' where the Higgs decays to two leptonic Z bosons. This channel provides a clean signature, in spite of the small leptonic branching ratios. We show that using fat jets the semi-leptonic ZZ mode significantly increases the number of signal events with a similar statistical significance as the leptonic mode.

description: Knowledge Graphs drive modern data fabrics, enabling frictionless access to and sharing of data. They have led to great advances in terms of data integration, interoperability and accessibility, and are a key instrument for transforming data into valuable and actionable knowledge. But while the benefits of knowledge graphs have become clear, the road to their implementation has often been long and complex and success has relied on the involvement of seasoned knowledge graph experts. For example, most ontology modeling tools available today target the ontology engineer, thus excluding domain experts and common business users from this process. Topics covered In this masterclass, we will present a new approach to semantic knowledge modeling based on metaphactory's visual and user-friendly interface for creating, exploring, visualizing, editing and documenting knowledge graph assets such as ontologies, taxonomies and instance data. The visual language translates to core elements of OWL, SHACL, SKOS and RDF, and results in knowledge graph assets based on open and flexible W3C standards. Specifically, this masterclass will cover: Visual creation of OWL/SHACL ontologies which allows business users and domain experts to contribute to the ontology engineering process Creation and management of SKOS taxonomies which allows business users and domain experts to capture business-relevant terms in organized vocabularies Data catalog integration - Creation, management and import of existing dataset metadata at integration time Creating model-driven data curation interfaces Creating model-driven search interfaces Benefits With this approach, creating a knowledge graph becomes a streamlined, end-to-end process where all relevant stakeholders are equally involved. This enables true knowledge democratization by connecting knowledge modeling, knowledge description, knowledge generation, and knowledge consumption under one umbrella.
Spectroscopic studies on the transport properties of ionic liquids

Publisher: name: Imperial College London

description: Ionic liquids are liquids composed entirely of ions. These ions are in constant motion. Ionic liquids have found use in a wide range of electrochemical applications, such as batteries, fuel cells and solar cells. In these applications they are exposed to various external forces including magnetic and electric fields. Gaining a thorough understanding of how these external forces affect the physical and chemical properties of ionic liquids is important; and it remains a fundamental challenge. In this study, fluorescence lifetime spectroscopy was utilised as a technique to gain an insight into the behaviour of the ions when experiencing electric fields. To enable the fluorescence measurements, synthetic processes were explored and developed to produce good quality ionic liquids with low fluorescence backgrounds. The physical and chemical properties of the ionic liquids were characterised by various established techniques such as nuclear magnetic resonance spectroscopy, mass spectrometry, impedance spectroscopy, cyclic voltammetry and elemental analysis. Upon the successful production of low fluorescence background ionic liquids, fluorescence lifetime experiments were conducted to monitor their local viscosities. In this study, molecular rotors were used as probes to estimate local viscosity of the ionic liquids. The fluorescence lifetimes were derived from a molecular rotor, 3,3'-diethylthiacarbocyanine (Cy3) which was dissolved in the ionic liquids (ca. 100 nM). The local viscosities were then estimated from a calibration curve developed from various ionic liquids and these values were also compared to those estimated from a calibration curve usually used for molecular solvent systems. Further to this, attempts to use the obtained correlation between fluorescence lifetime of Cy3 and viscosity to estimate the local viscosities of the ionic liquid under application of +2V potential were conducted. Even though the change of viscosity of ionic liquids was observed upon application of the +2V potential, the explanation to the observation is rather complicated due to many factors that can contribute to the viscosity change. Based on analysis and support data from the literature, the observed change in viscosity could be either attributed to change in molecular dynamics of ionic liquids as the potential is applied or it may be affected by instability of the indium-tin oxide (ITO) electrode over the applied potential which has the potential to cause dissolution of ITO components into ionic liquid system.

description: A detailed analysis of a coronal loop oscillation event is presented, using data from the Atmospheric Imaging Assembly (AIA) onboard the Solar Dynamics Observatory (SDO) for the first time. The loop oscillation event occurred on 2010 Oct 16, 19:05-19:35 UT, was triggered by an M2.9 GOES-class flare, located inside a highly inclined cone of a narrow-angle CME. This oscillation event had a number of unusual features: (i) Excitation of kink-mode oscillations in vertical polarization (in the loop plane); (ii) Coupled cross-sectional and density oscillations with identical periods; (iii) no detectable kink amplitude damping over the observed duration of four kink-mode periods ($P=6.3$ min); (iv) multi-loop oscillations with slightly ($\approx 10%$) different periods; and (v) a relatively cool loop temperature of $T\approx 0.5$ MK. We employ a novel method of deriving the electron density ratio external and internal to the oscillating loop from the ratio of Alfvénic speeds deduced from the flare trigger delay and the kink-mode period, i.e., $n_e/n_i=(v_A/v_{Ae})^2=0.08\pm0.01$. The coupling of the kink mode and cross-sectional oscillations can be explained as a consequence of the loop length variation in the vertical polarization mode. We determine the exact footpoint locations and loop length with stereoscopic triangulation using STEREO/EUVI-A data. We model the magnetic field in the oscillating loop using HMI/SDO magnetogram data and a potential field model and find agreement with the seismological value of the magnetic field, $B_{kink}=4.0\pm0.7$ G, within a factor of two.

We also report ab initio computing modeling of the high-pressure properties of these compounds, Pd2Mo3N, and Pt2Mo3N. We have found that the nitrides remain stable in the ambient-pressure cubic structure at least up to 50 GPa and determined their equation of state. All of them have a bulk modulus larger than 300 GPa. Single-crystal elastic constants have been calculated in order to quantify the stiffness of the investigated nitrides. We found that they should have a Vickers hardness similar to that of cubic spinel nitrides like gamma-Si3N4

The role of ethnic organizations : fostering integration and making connections in Canada and beyond
Creators: name: Ho, Mabel
Publisher: name: University of British Columbia
Year: 2018

description: Individuals have the option to maintain ties to their ancestral country while settling into Canada. These connections are called transnational practices, the activities and attachments individuals have across nation states, such as celebrating festivals or engaging in business investments based in the ancestral country. I conducted 61 interviews and engaged in 85.5 hours of participant observations in four ethnically-based organizations in Toronto to examine the factors that shape an individual’s participation in transnational practices, the meaning individuals give to their practices, and the identities that they develop. I draw attention to how organizations facilitate these practices, in part by lowering the cost to participating. Specifically, I demonstrate how organizations create the space for the development of social ties, which are critical for spreading information and building social pressure among group members. I compare political and cultural groups and find that political organizations were most explicit in connecting various types of transnational practices. As a result, individuals belonging to political organizations participated in a greater number and variety of transnational practices. I also examine the meaning individuals give to their engagement in transnational practices. I create a four-fold typology to categorize individuals’ transnational practices as rooted, multiple, wavering, or romantic connections. I show how the language spoken at events and the activities hosted by organizations shape the meanings individuals attach to their practices. Last, I examine how individuals create and develop their identities within organizations. I argue that these organizations help foster particular ways of enacting the Canadian hyphen. Individuals can come to see their Canadian and ancestral country identities as connected in different ways, what I label as core, contextual, or composite identities. This dissertation highlights the critical role that ethnic organizations can play for newcomers, established co-ethnic members, and larger society. Unpacking the role of these organizations gives insight into the complex ways that individuals integrate into Canada as a whole while maintaining connections beyond our borders and speaks to the larger issues of inclusion and integration in society.

description: Under the white Gaussian noise model with the noise level ε → 0, we study minimax nonparametric hypothesis testing problem 퐻0 : ƒ = 0 on unknown function ƒ ∈ L2(0,1). We consider alternative sets that are determined a regularity constraint in the Sobolev norm and we suppose that signals are bounded away from the null either in L2-norm or in L∞-norm. Analogous problems are considered in the sequence space. If type I error probability α ∈ (0,1) is fixed, then these problems were studied in book [13]. In this paper we consider the case α → 0. We obtain either sharp distinguishability conditions or sharp asymptotics of the minimax type II error probability in the problem. We show that if α is "not too small", then there exists natural extension of results [13], whenever if α is "very small", then we obtain classical asymptotics and distinguishability conditions for small α. Adaptive problems are studied as well.

description: Molten metallic nanoparticles have recently been used to construct graphene nanostructures with crystallographic edges. The mechanism by which this happens, however, remains unclear. Here, we present a simple model that explains how a droplet can etch graphene. Two factors possibly contribute to this process: a difference between the equilibrium wettability of graphene and the substrate that supports it, or the large surface energy associated with the graphene edge. We calculate the etching velocities due to either of these factors and make testable predictions for evaluating the significance of each in graphene etching. This model is general and can be applied to other materials systems as well. As an example, we show how our model can be used to extend a current theory of droplet motion on binary semiconductor surfaces.

A investigação aqui apresentada teve como objetivo caracterizar a implementação de Sistemas Aumentativos e Alternativos de Comunicação (SAACs) junto dos indivíduos com Multideficiência integrados nas Unidades de Apoio Especializado (UAEs) de Portugal Continental, durante o ano letivo 2015-2016. Pretendeu-se ainda efetuar uma determinação qualitativa da frequência de ‘Boas Práticas’ inerentes ao uso de SAACs nessas mesmas UAEs e durante o mesmo período. Foi elaborado um questionário eletrónico destinado a um representante – docente em Educação Especial – de cada uma das 353 UAEs de Portugal Continental. A taxa de resposta foi de apenas 15% da amostra considerada para estudo. Os dados obtidos mostram que, durante o ano letivo 2015-2016, algumas UAEs não dispunham de SAACs para garantir a comunicação efetiva dos indivíduos com Multideficiência impossibilitados de falar. Os dados apontam ainda para lacunas ao nível da implementação de ‘Boas Práticas’ inerentes ao uso de SAACs, impondo-se a necessidade de investigação futura.

Best Practices in the provision of Augmentative and Alternative Communication Systems for students with Profound Intellectual and Multiple Disabilities in specialized education units in mainland Portugal: an unfulfilled need?

The present study aimed at a characterization of the implementation of Augmentative and Alternative Communication Systems (AACSs) for individuals with Profound Intellectual and Multiple Disabilities in Portuguese UAEs (“Unidades de Apoio Especializado para a Educação de Alunos com Multideficiência e Surdocegueira Congénita”), in the school year of 2015/2016. Also, it aimed at assessing the frequency of ‘Best Practices’ in the provision of AACs in these same UAEs. An electronic questionnaire has been created aimed at being filled by one special education teacher per UAE (total of UAEs: N=353). The questionnaire response rate was low: 15% of the sample here considered for analysis. Obtained data showed that, in the school year of 2015-2016, some UAEs, did not had AACSs available for individuals with PIMD, who could not use speech, to communicate effectively. Also, data pointed to some failures in the implementation of the Best Practices in the provision of AACSs, thus calling for additional research.

description: NGC 4945 is a Seyfert 2 galaxy at a distance of 3.82 Mpc. Its relative proximity has permitted a detailed SMA study of the circumnuclear molecular gas in a galaxy exhibiting an AGN. Based on an analysis of the high-resolution velocity field of the central region (20" X 20", 1" = 19 pc), we demonstrate that the S-shaped structure of the isovelocity contours is well reproduced by the numerical results of a two dimensional hydrodynamical simulation. In particular, the velocity structure is represented by the bending produced by a shock along the spiral density waves, which are excited at the outer-inner Lindblad resonance by a fast rotating bar. The simulated density map reveals a pair of tightly wound spirals in the center which pass through most of the ring-like (claimed to be a circumnuclear starburst ring by other authors) high intensity region in the observations as well as intersect several Pa$α$ emission line knots located outside the ring-like region. The calculated mass inflow rate at a scale of 50 pc is about three times the inferred mass accretion rate of the AGN of NGC 4945. We find that self-gravity of the gas is important and should be included in our model for NGC 4945. The model is compared with the gas orbit model discussed in Lim et al. (2009), and it is shown that the hydrodynamic model provides a better match to the observed position-velocity diagram and, hence, provides a more reliable prediction of the outer inner Lindblad resonance position.

title: A Digital One Degree of Freedom Model of an Electromagnetic Position Sensor
Creators: name: Weinmann, Michelle  Elizabeth
Publisher: name: Old Dominion University Libraries
Year: 2021

description: The purpose of this project was to improve an existing system currently in use by NASA Langley Research Center (LaRC). The 6-inch Magnetic Suspension and Balance System (MSBS) built at MIT is operational with control in three degrees of freedom, with two additional degrees of freedom exhibiting passive stability. The means for measuring model displacement within the magnetic environment is an Electromagnetic Position Sensor (EPS), consisting of excitation coils at 20 kHz and multiple sets of pickup coils. The pickup coil voltages are proportional to model displacement in each degree of freedom. However, the EPS electronic signal processing system is analog and outdated; setup and adjustment are time consuming. The task was to construct a one degree of freedom model of the EPS including its electronics system in order to explore digital signal processing. The model core is allowed only axial displacement for simplicity; this model coil set is essentially a Linear Variable Differential Transformer (LVDT). The source signal was chosen to be 2.36 kHz for convenience, with scaling up to the full size system at 20 kHz possible. An amplification and filtering circuit board was constructed to modify the signal for the proper functionality of the model EPS. By comparing the reference or excitation coil signal and the measured or pickup coil signal by means of a digital phase measurement method using cross-correlation analysis, the digital algorithm resolves the phase shift between the two signals and their amplitude ratio. The key proof of concept is the digital signal processing algorithm; since the defining characteristics of any signal are the amplitude and phase this algorithm can be adapted to suit various control and setup needs of the MSBS and EPS. By proving that a digital interface with the EPS is possible, the analog interface can be replaced with a digital system.

A abordagem denominada Health Promoting Universities (HPU) ou Universidades Promotoras da Saúde (UPS) – Organização Mundial da Saúde (OMS) considera que as Instituições de Ensino Superior (IES) possuem um papel preponderante na preservação da saúde e bem-estar da comunidade acadêmica. As IES são, sob este paradigma, conduzidas pelos marcos conceituais da promoção da saúde (PS), e por valores interdisciplinares como inclusão, equidade, justiça social e sustentabilidade. A Bioética, em conjunto com as UPS e a PS, apresenta-se como uma ferramenta reflexiva, mutuamente compartilhada e interdisciplinar que objetiva a adequação das ações que compreendem a vida e a cidadania, em seu caráter equitativo e inclusivo, no contexto da Educação Superior. Neste texto a Bioética busca refletir sobre a PS docente nas IES, contribuindo para a construção de processos qualificados de ações em saúde docente.

Bioethics and promotion of teacher health in higher education: an interface required

The Health Promoting Universities (HPU) - World Health Organization (WHO) approach considers that Higher Education Institutions (HEI) play a preponderant role in preserving the health and well-being of the academic community. HEIs under this paradigm are driven by conceptual frameworks of health promotion (HP), and by interdisciplinary values such as inclusion, equity, social justice and sustainability. Bioethics, together with HPU and HP, presents itself as a reflexive, mutually shared and interdisciplinary tool that aims at the adequacy of actions that comprise life and citizenship, in its equitable and inclusive character, in the context of Higher Education. In this text Bioethics seeks to reflect on the teaching HP in HEI, contributing to the construction of qualified processes of actions in teacher’s health.

On Tractable Exponential Sums

description: We consider the problem of evaluating certain exponential sums. These sums take the form $\sum_{x_1,...,x_n \in Z_N} e^{f(x_1,...,x_n) {2 πi / N}} $, where each x_i is summed over a ring Z_N, and f(x_1,...,x_n) is a multivariate polynomial with integer coefficients. We show that the sum can be evaluated in polynomial time in n and log N when f is a quadratic polynomial. This is true even when the factorization of N is unknown. Previously, this was known for a prime modulus N. On the other hand, for very specific families of polynomials of degree \ge 3, we show the problem is #P-hard, even for any fixed prime or prime power modulus. This leads to a complexity dichotomy theorem - a complete classification of each problem to be either computable in polynomial time or #P-hard - for a class of exponential sums. These sums arise in the classifications of graph homomorphisms and some other counting CSP type problems, and these results lead to complexity dichotomy theorems. For the polynomial-time algorithm, Gauss sums form the basic building blocks. For the hardness results, we prove group-theoretic necessary conditions for tractability. These tests imply that the problem is #P-hard for even very restricted families of simple cubic polynomials over fixed modulus N.

description: We present the first systematic investigation into the metallicity gradients in galaxy close pairs. We determine the metallicity gradients for 8 galaxies in close pairs using HII region metallicities obtained with high signal-to-noise multi-slit observations with the Keck LRIS Spectrograph. We show that the metallicity gradients in close pairs are significantly shallower than gradients in isolated spiral galaxies such as the Milky Way, M83, and M101. These observations provide the first solid evidence that metallicity gradients in interacting galaxies are systematically different from metallicity gradients in isolated spiral galaxies. Our results suggest that there is a strong relationship between metallicity gradients and the gas dynamics in galaxy interactions and mergers.

description: As part of the science demonstration phase of the Herschel mission of the Gould Belt Key Program, the Aquila Rift molecular complex has been observed. The complete ~ 3.3deg x 3.3deg imaging with SPIRE 250/350/500 micron and PACS 70/160 micron allows a deep investigation of embedded protostellar phases, probing of the dust emission from warm inner regions at 70 and 160 micron to the bulk of the cold envelopes between 250 and 500 micron. We used a systematic detection technique operating simultaneously on all Herschel bands to build a sample of protostars. Spectral energy distributions are derived to measure luminosities and envelope masses, and to place the protostars in an M_env - L_bol evolutionary diagram. The spatial distribution of protostars indicates three star-forming sites in Aquila, with W40/Sh2-64 HII region by far the richest. Most of the detected protostars are newly discovered. For a reduced area around the Serpens South cluster, we could compare the Herschel census of protostars with Spitzer results. The Herschel protostars are younger than in Spitzer with 7 Class 0 YSOs newly revealed by Herschel. For the entire Aquila field, we find a total of ~ 45-60 Class 0 YSOs discovered by Herschel. This confirms the global statistics of several hundred Class~0 YSOs that should be found in the whole Gould Belt survey.

Adaptability of Pacific North America's small-scale fisheries to climate change
Creators: name: Ang, Melanie
Publisher: name: University of British Columbia
Year: 2018

description: This thesis compares and contrasts the projected impacts of climate change on small- and large- scale fisheries and seeks to understand key characteristics of their vulnerability and adaptability to climate change using the Pacific North America region, including Alaska, Canada, USA West Coast and Mexico, as a case study. I undertake an interdisciplinary approach and use both quantitative and qualitative methodologies to examine the ecological and social-economic dimensions of vulnerabilities, impacts and adaptability of climate change on fisheries. I identify 312 exploited species that are important to small- or large- scale fisheries and apply the Dynamic Bioclimate Envelope Model to project changes in maximum catch potentials and their distributions separately for by small- and large- scale fisheries under the upper (RCP 8.5) and lower (RCP 2.6) greenhouse gas emission scenarios between year 2000 and 2080. Subsequently, I apply a vulnerability assessment framework to three case illustrations from the Pacific North America region: Alaska’s cod fishery (USA), Monterey Bay’s wetfish fishery (USA) and Sonora’s cannonball jellyfish fishery (Mexico) to understand key commonalities and differences that would enable small-scale fisheries and large-scale fisheries to adapt to the climate-induced impacts. The results indicate a projected increase in maximum catch potential for small-scale fisheries (RCP 2.6: +1.7%; RCP 8.5: +16.7%) compared to large-scale fisheries (RCP 2.6: -7.2%; RCP 8.5: -10.7%) across the region by 2080 relative to 2000, with varying patterns between different countries’ waters. The increasing trend in catch potential is contributed by a few exploited species with significant projected gains such as California market squid (Loligo opalescens). The ability of fisheries and fishing communities to adapt to these ecological changes will determine their continued viability. Case illustrations suggest that having lower operational cost, flexibility in gear type, flexible management, clear regulations, strong social capital and well-educated communities tend to relate with lower vulnerability and stronger adaptive capacities to climate change.

description: Millimeter-wave transistor based technologies are steadily progressing in areas such as electrical performance (noise and bandwidth), thermal management, power consumption, and miniaturization of complex receiver functionality, and are becoming a viable option for future large-format (> 20 pixels) heterodyne arrays for radio-astronomy. InP and Si-based MMIC technologies have progressed enough so the promise of extreme receiver miniaturization in a small footprint is quickly becoming reality. InP has continued with the dominance in mm-wave cryogenic electrical performance, whereas Si-based circuits have emerged as good candidates in terms of high integration of functionality, and low power consumption. In this talk, we will show recent developments in the design of InP/Si active devices, and discuss about hybrid integration (InP/Si) with the aim of prototyping modules that mix the best of both technologies, increasing the performance of future large mm-wave arrays.

 Notes. This species is difficult to differentiate from Arcyria leiocarpa, especially in the intermediate forms. The principal feature distinguishing between the two species was the orientation of the spirals in the capillitium, i.e., arranged from left to right in the specimens identified as H. pseudoleiocarpa, and in the opposite sense in those identified as A. leiocarpa.
