description: The lightest Xenon isotopes are studied in the framework of the Interacting Shell Model (ISM). The valence space comprises all the orbits lying between the magic closures N=Z=50 and N=Z=82. The calculations produce collective deformed structures of triaxial nature that encompass nicely the known experimental data. Predictions are made for the (still unknown) N=Z nucleus 108-Xe. The results are interpreted in terms of the competition between the quadrupole correlations enhanced by the pseudo-SU(3) structure of the positive parity orbits and the pairing correlations brought in by the 0h11/2 orbit. We have studied as well the effect of the excitations from the 100-Sn core on our predictions. We show that the backbending in this region is due to the alignment of two particles in the 0h11/2 orbit. In the N=Z case, one neutron and one proton align to J=11 and T=0. In 110-Xe and 112-Xe the alignment begins in the J=10 T=1 channel and it is dominantly of neutron neutron type. Approaching the band termination the alignment of a neutron and a proton to J=11 and T=0 takes over. In a more academic mood, we have explored the role of the isovector and isoscalar pairing correlations on the structure on the yrast bands of 108-Xe and 110-Xe and examined the role of the isovector and isoscalar pairing condensates in these N~Z nuclei.

A DEVELOPEMENTAL, FORMATIVE EVALUATION TO INFORM IMPLEMENTATION OF BIDIRECTIONAL HEALTH INFORMATION EXCHANGE IN COMMUNITY PHARMACIES

description: Although community pharmacists have further reduced medication errors and improved care with access to patient data through unidirectional health information exchange (HIE), access to routine patient data has not been sustained. Several barriers to sustaining use and access of HIE in community pharmacies have been noted, such as lack of implementation supports and technological restrictions. Further, pharmacists and pharmacy technicians have not been involved in the development of HIE systems for their use previously. My research aims to optimize HIE access for community pharmacists through our co-developed HIE interface prototype specifically for use by community pharmacy teams in collaboration with PioneerRx, a pharmacy dispensing software system and our state HIE, the Indiana Health Information Exchange (IHIE), and provide supports for the sustainability of community pharmacist access to HIE. Therefore, the objectives of my research are to 1) conduct a formative usability evaluation of the HIE interface prototype with community pharmacists and pharmacy technicians to inform strategies to improve the HIE interface design for future implementation in community pharmacies (“Study One”) and 2) identify the potential barriers, facilitators, and recommendations for HIE implementation in community pharmacies through semi-structured interviews to create a curated list of resources to address identified implementation needs to assist with the future implementation of HIE (“Study Two”). The findings from Study One demonstrate the HIE interface prototype was viewed favorably by pharmacists and pharmacy technicians, with the average System Usability Scale (SUS) score 69 (scale 0 – 100, where 100 is the best). Pharmacists reported higher satisfaction than technicians on average (74 vs. 65, respectively). Key problems identified included accessibility of HIE links and placement in the existing workflow and application label name clarifications. The same eight pharmacists and eight pharmacy technicians, with the addition of seven patients, completed interviews in Study Two. Five barriers, four facilitators, and two recommendations were identified. These were further characterized into four key implementation needs: instruction on how to use HIE, guidance on workflow and team roles, and provider and patient facing resources for discussing HIE. Curated draft implementation resource items that are responsive to all four key implementation needs are in development. The combination of findings from Study One and Study Two create the blueprint for pharmacy-team informed implementation of HIE in community pharmacies.

description: Functions satisfying a defective renewal equation arise commonly in applied probability models. Usually these functions don't admit a explicit expression. In this work we consider to approximate them by means of a gamma-type operator given in terms of the Laplace transform of the initial function. We investigate which conditions on the initial parameters of the renewal equation give optimal order of uniform convergence in the approximation. We apply our results to ruin probability in the classical risk model, paying special attention to mixtures of gamma claim amounts.

description: This paper discusses the issue of gaining independence by young people who, owing to their adverse life circumstances, face a difficult start in adult life. Beginning an independent life, even with the support and aid of relatives, may involve confronting the challenges of everyday bleak adult life. Gaining independence is much more difficult for young people who leave educational and care centers (care leavers), or youth who avoid contacts with adults, and consequently live in a street milieu. The aim of this text is to focus attention on the process of gaining independence by the street children. It considers if it is possible for them at all, and what should gaining independence by street children involve, and what should indicate the completion of this process. The paper asks who supports these children, and introduces them to adult life? This is a very unique target group for care providers, and social workers whose assistance is limited to those activities carried out only in the streets. Hence, can street workers, that is social workers who work with street children, guide them with respect to gaining independence? The text addresses these problematical issues, and so considers the notion of street children’s gaining independence.
description: W artykule poruszono problematykę usamodzielnienia się młodych ludzi, którzy ze względu na niesprzyjające warunki życiowe mają trudny start w dorosłe życie. Rozpoczęcie niezależnego życia, nawet przy wsparciu i pomocy bliskich, może wiązać się z wyzwaniami codziennego ponurego dorosłego życia. Osiągnięcie samodzielności jest znacznie trudniejsze dla młodych ludzi opuszczających placówki wychowawczo-opiekuńcze (wychowanków) lub młodzieży, która unika kontaktów z dorosłymi i w konsekwencji żyje w środowisku ulicznym. Celem tego tekstu jest zwrócenie uwagi na proces usamodzielnienia się dzieci ulicy. Autorka zastanawia się, czy w ogóle jest to możliwe i na czym powinno polegać usamodzielnienie się dzieci ulicy i co powinno wskazywać na zakończenie tego procesu, kto wspiera te dzieci i wprowadza je w dorosłe życie. To bardzo wyjątkowa grupa docelowa dla opiekunów i pracowników socjalnych, których pomoc ogranicza się do czynności wykonywanych wyłącznie na ulicy. Czy zatem streetworkerzy, czyli pracownicy socjalni pracujący z dziećmi ulicy, mogą pokierować nimi w kwestii uzyskania niezależności? Tekst porusza te problematyczne kwestie, a więc rozważa pojęcie niezależności dzieci ulicy.

description: The recently derived long-range two-pion exchange (TPE) contributions to the nuclear current operator which appear at next-to-leading order (NLO) of the chiral expansion are used to describe electromagnetic processes. We study their role in the photodisintegration of 2H and 3He and compare our predictions with experimental data. The bound and scattering states are calculated using five different parametrizations of the chiral next-to-next-to-leading order (N2LO) nucleon-nucleon (NN) potential which allows us to estimate the theoretical uncertainty at a given order in the chiral expansion. For some observables the results are very close to the predictions based on the AV18 NN potential and the current operator (partly) consistent with this force. In the most cases, the addition of long-range TPE currents improved the description of the experimental data.

description: We study numerically the non-equilibrium critical properties of the Ising model defined on direct products of graphs, obtained from factor graphs without phase transition (Tc = 0). On this class of product graphs, the Ising model features a finite temperature phase transition, and we find a pattern of scaling behaviors analogous to the one known on regular lattices: Observables take a scaling form in terms of a function L(t) of time, with the meaning of a growing length inside which a coherent fractal structure, the critical state, is progressively formed. Computing universal quantities, such as the critical exponents and the limiting fluctuation-dissipation ratio X_\infty, allows us to comment on the possibility to extend universality concepts to the critical behavior on inhomogeneous substrates.

Mass Constraints from Eclipse Timing in Double White Dwarf Binaries

description: I demonstrate that an effect similar to the Roemer delay, familiar from timing radio pulsars, should be detectable in the first eclipsing double white dwarf (WD) binary, NLTT 11748. By measuring the difference of the time between the secondary and primary eclipses from one-half period (4.6 s), one can determine the physical size of the orbit and hence constrain the masses of the individual WDs. A measurement with uncertainty <0.1 s---possible with modern large telescopes---will determine the individual masses to +/-0.02 Msun when combined with good-quality (<1 km/s) radial velocity data, although the eccentricity must also be known to high accuracy (+/- 1e-3). Mass constraints improve as P^{-1/2} (where P is the orbital period), so this works best in wide binaries and should be detectable even for non-degenerate stars, but such constraints require the mass ratio to differ from one and undistorted orbits.

description: T. Li {\it et al.}[Phys. Rev. C {\bf 81}, 034309 (2010)] have analyzed their measured breathing-mode energies of some tin isotopes in terms of a first-order leptodermous expansion, and find for the symmetry-incompressibility coefficient $K_τ$ the value of -550 $\pm$ 100 MeV. Removing an approximation that they made, we find that the first-order estimate of $K_τ$ shifts to -661 $\pm$ 144 MeV. However, taking into account higher-order terms in the leptodermous expansion shows that the data are compatible with the significantly lower magnitudes indicated by both another experiment and some theoretical estimates.

description: In this paper we describe our work on unsupervised adaptation of the acoustic model of our simultaneous lecture translation system. We trained a speaker independent acoustic model, with which we produce automatic transcriptions of new lectures in order to improve the system for a specific lecturer. We compare our results against a model that was trained in a supervised way on an exact manual transcription. We examine four different ways of processing the decoder outputs of the automatic transcription with respect to the treatment of pronunciation variants and noise words. We will show that, instead of fixating the latter informations in the transcriptions, it is of advantage to let the Viterbi algorithm during training decide which pronunciations to use and where to insert which noise words. Further, we utilize word level posterior probabilities obtained during decoding by weighting and thresholding the words of a transcription.
Determining the knowledge, attitudes, and behaviours of people exposed to diesel exhaust at the workplace
Creators: name: Pui, Mandy
Publisher: name: University of British Columbia
Year: 2016

description: Background: Diesel exhaust (DE) is a common exposure in Canadian workplaces. The International Agency for Research on Cancer (IARC) classified DE as being carcinogenic to humans in 2012. Health and safety agencies provide information about DE and the mitigation strategies that can be used to reduce the exposure of individuals. However, there is little known about the extent to which those potentially exposed in the workplace understand the risks of DE or have recently changed behaviours to minimize workplace exposure to DE. Objectives: To identify exposure-related knowledge, attitudes and behaviours of individuals occupationally exposed to diesel exhaust; to reveal strengths, knowledge gaps and misperceptions therein. Methods: A Mental Models approach was used to gather information about current scientific understanding of DE exposure hazards and the ways in which exposure can be reduced. Thirty individuals in British Columbia who were regularly exposed to occupational DE were interviewed. The audio was recorded, transcribed, grouped together, and examined to draw out themes around DE awareness, hazard assessment and risk reduction behaviours. These themes were then compared and contrasted with existing grey and research literature in order to reveal strengths, gaps and misperceptions regarding exposure to DE. Results: Study participants were aware and concerned about DE but had incomplete and sometimes incorrect understanding of exposure pathways, health effects, and effective strategies to reduce their exposures. The perceived likelihood of exposure to diesel exhaust was significantly greater compared to that of other work hazards (p<0.01), whereas the difference for their perceived severity of consequences was not significant. There was no universally perceived main source of information regarding DE, and participants generally distrusted sources of information based on their past experience with the source. Most of the actions that were taken to address DE exposure fell into the area of administrative controls such as being aware of sources of DE and avoiding these sources. Discussion: This study of the knowledge, attitude, and behaviour of those occupationally exposed to diesel exhaust found, most notably, that more education and training and the creation of a health effects inventory regarding diesel exhaust exposure were desired.

description: A miniature opposed-anvil high-pressure cell has been developed for magnetic measurement in a commercial superconducting quantum interference device (SQUID) magnetometer. Non-magnetic anvils made of composite ceramic material were used to generate high-pressure with a Cu-Be gasket. We have examined anvils with different culet sizes (1.8, 1.6, 1.4, 1.2, 1.0, 0.8 and 0.6 mm). The pressure generated at low temperature was determined by the pressure dependence of the superconducting transition of lead (Pb). The maximum pressure $P_{max}$ depends on the culet size of the anvil: the values of $P_{max}$ are 2.4 and 7.6 GPa for 1.8 and 0.6 mm culet anvils, respectively. We revealed that the composite ceramic anvil has potential to generate high pressure above 5 GPa. The background magnetization of the Cu-Be gasket is generally two orders of magnitude smaller than the Ni-Cr-Al gasket for the indenter cell. The present cell can be used not only with ferromagnetic and superconducting materials with large magnetization but also with antiferromagnetic compounds with smaller magnetization. The production cost of the present pressure cell is about one tenth of that of a diamond anvil cell. The anvil alignment mechanism is not necessary in the present pressure cell because of the strong fracture toughness (6.5 MPa${\cdot}$m$^{1/2}$) of the composite ceramic anvil. The simplified pressure cell is easy-to-use for researchers who are not familiar with high pressure technology. Representative results on the magnetization of superconducting MgB$_2$ and antiferromagnet CePd$_5$Al$_2$ are reported.

description: The author analyses categories of work and career, understood as the space of experiencing personal satisfaction and self-efficacy. In this regard work has an emancipatory function, especially for women, for whom professional activity is a way to become independent. Different meanings of work for women are reconstructed in relation to the ways of their professional engagement: ‘women of work’, and ‘women of career’. The author is focused on the second type. As an example of a ‘woman of career’ it is described a case of one dual-career family interviewed, as a part of bigger biographical research on gender equality in dual-career marriages. The case analysis shows that woman’s professional biography is constructed around the central category of continuous development. Professional career becomes a source of empowerment, release from traditionally assigned gender roles, and a space of acknowledgement of human dignity.

W takim ujęciu praca pełni emancypacyjną funkcję, zwłaszcza w odniesieniu do kobiet, dla których aktywność zawodowa jest sposobem na zdobycie autonomii. Różne znaczenia przypisywane pracy zawodowej kobiet zostały zrekonstruowane w odniesieniu do poziomu ich zawodowego zaangażowania, na podstawie którego wyróżniono dwie grupy: „kobiety pracy” i „kobiety kariery”. Szczegółowej analizie poddano znaczenia pracy zawodowej dla drugiej grupy kobiet. Jako przykład „kobiety kariery” przedstawiono przypadek kobiety i jej męża funkcjonujących w rodzinie o równoległych karierach rodziców (dual-career family), z którymi przeprowadzono wywiady w ramach większego projektu badań biograficznych dotyczących partnerstwa. Analizy pokazują, że kobieca biografia zawodowa jest konstruowana wokół centralnej kategorii, jaką jest nieustanny rozwój. Kariera zawodowa staje się źródłem upodmiotowienia i uwolnienia od tradycyjnie przypisanych ról związanych z płcią.

description: In recent papers we put forth a new interpretation of quantum mechanics, colloquially known as ``the Montevideo interpretation''. This interpretation is based on taking into account fundamental limits that gravity imposes on the measurement process. As a consequence one has that situations develop where a reduction process is undecidable from an evolution operator. When such a situation is achieved, an event has taken place. In this paper we sharpen the definition of when and how events occur, more precisely we give sufficient conditions for the occurrence of events. We probe the new definition in an example. In particular we show that the concept of undecidability used is not ``FAPP'' (for all practical purposes), but fundamental.

description: A method is described for levitating micron-sized few layer graphene flakes in a quadrupole ion trap. Starting from a liquid suspension containing graphene, charged flakes are injected into the trap using the electrospray ionization technique and are probed optically. At micro-torr pressures, torques from circularly polarized light cause the levitated particles to rotate at frequencies >1 MHz, which can be inferred from modulation of light scattering off the rotating flake when an electric field resonant with the rotation rate is applied. Possible applications of these techniques will be presented, both to fundamental measurements of the mechanical and electronic properties of graphene and to new approaches to graphene crystal growth, modification and manipulation.

Study of Si-Ge interdiffusion with highly n-type doping
Creators: name: Cai, Feiyang
Publisher: name: University of British Columbia
Year: 2016

description: Silicon photonics has emerged as an effective solution to overcome the wiring limit imposed on electronic device (e.g. transistors) density and performance with continued scaling. In the past few decades, researchers all over the world have invested extensive effort on finding solutions to a Si-compatible lasing material system. Recently, Ge-on-Si lasers were demonstrated as promising candidates. Heavy n-type doping in Ge is the key technique to realize Ge lasing. However, Si-Ge interdiffusion during high-temperature growth or fabrication steps changes the distribution of Ge fraction and increases atomic intermixing, which degrades the device performance. Studies on the Si-Ge interdiffusion with high Ge fraction and P doping effects are not available.The subject is of technical significance for the structure, doping and process design of Ge-on-Si lasers and Ge based MOSFET. In this work, Si-Ge interdiffusion under high n-type doping was investigated both by experiments and by theoretical analysis: 1)Si–Ge interdiffusion with different P doping configurations was investigated. Significant interdiffusion happened when the Ge layer was doped with P at 10¹⁹ cm-³ after defect annealing, which resulted in a SiGe-alloy region at the Si-Ge interface. The thickness of this SiGe alloy was more than 150 nm. With high P-doped Ge, Si–Ge interdiffusivity is enhanced 10–20 times in the XGe > 0.7 region compared with the control sample without P doping. The phenomenon is attributed to the Fermi-level effect. Due to the high P concentration peak in the Si-Ge interdiffusion region, the concentration of negatively charged vacancy was greatly increased and thus the interdiffusivity of Si–Ge. Next, the impact of the Fermi-level effect on Si-Ge interdiffusion was further investigated by theoretical modeling. 2) Ge/Si0.25Ge0.75/Ge multilayered structures with no P doping and high P doping were investigated. A model of Si-Ge interdiffusion under high n-type doping was proposed to describe the impact of the Fermi-level effect. By fitting to the SIMS data from experiments with different anneal temperatures, it was found out that the Fermi-enhancement factor of Si-Ge interdiffusion was quadratically dependent on the ratio of electron concentration over intrinsic electron concentration (n/ni). This suggests that for Ge fractions from 0.75 to 1 under high n-type doping, Si-Ge interdiffusion is dominated by vacancies with double negative charge (V²-). This is the first work on the quantitative modeling of Si-Ge interdiffusion with high n-type doping.

description: Reversible logic design has become one of the promising research directions in low power dissipating circuit design in the past few years and has found its application in low power CMOS design, digital signal processing and nanotechnology. This paper presents the efficient design approaches of fault tolerant carry skip adders (FTCSAs) and compares those designs with the existing ones. Variable block carry skip logic (VBCSL) using the fault tolerant full adders (FTFAs) has also been developed. The designs are minimized in terms of hardware complexity, gate count, constant inputs and garbage outputs. Besides of it, technology independent evaluation of the proposed designs clearly demonstrates its superiority with the existing counterparts.

description: Supersymmetric heterotic string models, built from a Calabi-Yau threefold $X$ endowed with a stable vector bundle $V$, usually start from a phenomenologically motivated choice of a bundle $V_v$ in the visible sector, the spectral cover construction on an elliptically fibered $X$ being a prominent example. The ensuing anomaly mismatch between $c_2(V_v)$ and $c_2(X)$, or rather the corresponding differential forms, is often 'solved', on the cohomological level, by including a fivebrane. This leads to the question whether the difference can be alternatively realized by a further stable bundle. The 'DRY'-conjecture of Douglas, Reinbacher and Yau in math.AG/0604597 gives a sufficient condition on cohomology classes on $X$ to be realized as the Chern classes of a stable sheaf. In arXiv:1010.1644 we showed that infinitely many classes on $X$ exist for which the conjecture ist true. In this note we give the sufficient condition for the mentioned fivebrane classes to be realized by a further stable bundle in the hidden sector. Using a result obtained in arXiv:1011.6246 we show that corresponding bundles exist, thereby confirming this version of the DRY-Conjecture.

description: In this paper we present generic properties of quantum transport in mono-layer graphene. In the scheme of the Kubo-Geenwood formula, we compute the square spreading of wave packets of a given energy with is directly related to conductivity. As a first result, we compute analytically the time dependent diffusion for pure graphene. In addition to the semi-classical term a second term exists that is due to matrix elements of the velocity operator between electron and hole bands. This term is related to velocity fluctuations i.e. Zitterbewegung effect. Secondly, we study numerically the quantum diffusion in graphene with simple vacancies and pair of neighboring vacancies (divacancies), that simulate schematically oxidation, hydrogenation and other functionalisations of graphene. We analyze in particular the time dependence of the diffusion and its dependence on energy in relation with the electronic structure. We compute also the mean free path and the semi-classical value of the conductivity as a function of energy in the limit of small concentration of defects.

Cisplatin partially impedes lung adenocarcinoma-mediated M2 macrophage polarization

description: Lung cancer is the leading cause of cancer mortality and at 18%, has one of the lowest five-year survival rates of all malignancies. The majority of patients (>80%) are diagnosed with locally advanced or metastatic disease for which the standard of care is platinum-based doublet chemotherapy. However, chemotherapy has modest effects on overall survival, highlighting the need for novel and more effective treatments. Within the past decade, the role of the immune system in tumorigenesis has become increasingly appreciated. Targeting the immune cells within the tumor microenvironment is a growing field of study that holds exciting therapeutic potential. Macrophages are a prominent immune cell type in the lung and lung tumors. It is widely accepted that a spectrum of macrophage activation states exists, with the exact phenotype dependent upon the precise composition of signals within the microenvironment. At opposite ends of this spectrum there exist M1 macrophages which are pro-inflammatory and have antitumor functions, and M2 macrophages which are anti-inflammatory and act in wound healing and thus promote tumorigenesis. I hypothesized that macrophage differentiation is skewed by lung adenocarcinoma cells to an M2 phenotype and that cisplatin, a commonly prescribed chemotherapeutic, affects macrophage polarity. I co-cultured human monocytes with human lung adenocarcinoma cells in the absence and presence of physiologically relevant concentrations of cisplatin. Co-cultured macrophages displayed increased differentiation and an M2 polarity, in part potentially through IL-6 secretion by tumor cells. Cisplatin impeded macrophage differentiation, with treated macrophages displaying decreased size, granularity, and surface marker expression; however, CD206 expression, an M2 marker, remained elevated, suggesting a role for CD206 in response to treatment. Additionally, I optimized single cell analysis of clinical specimens in preparation for future projects, specifically ex vivo analysis of the effect of standard first line chemotherapy on macrophage polarity and other immune cells in advanced non-small cell lung cancer. Collectively, this work has demonstrated that macrophage polarity is affected by lung adenocarcinoma cells and by cisplatin. Moreover, the optimization of single cell analysis has prepared for the study of the effect of chemotherapy on macrophage polarity over the course of treatment using more physiologically representative specimens.

description: Details of the discovery of a new X-ray source, IGR J18462-0223, on October 12, 2007, during a short (several hours), intense (~ 35 mCrab at the peak) outburst of hard radiation by the IBIS/ISGRI gamma-ray telescope onboard the INTEGRAL observatory are given. The detection of another earlier outburst from this source occurred on April 28, 2006, in the archival data of the telescope is reported. We present the results of the source's localization and our spectral/timing analysis of the observational data. The source may turn out to be yet another representative of the continuously growing population of fast X-ray transients, which are the focus of attention because of the identification of their optical counterparts with early-type supergiants.
Re-study on the contribution of scalar potential and spectra of $c\bar c$, $b\bar b$ and $b\bar c(\bar b c)$ families

description: We indicated in our previous work that for QED the role of the scalar potential which appears at the loop level is much smaller than that of the vector potential and in fact negligible. But the situation is different for QCD, one reason is that the loop effects are more significant because $α_s$ is much larger than $α$, and secondly the non-perturbative QCD effects may induce a sizable scalar potential. In this work, we phenomenologically study the contribution of the scalar potential to the spectra of charmonia, bottomonia and $b\bar c(\bar b c)$ family. Taking into account both vector and scalar potentials, by fitting the well measured charmonia and bottomonia spectra, we re-fix the relevant parameters and test them by calculating other states of not only the charmonia, bottomonia, but also further the $b\bar c$ family. We also consider the Lamb shift of the spectra.

description: Given a graph $G$, an identifying code $C \subseteq V(G)$ is a vertex set such that for any two distinct vertices $v_1,v_2\in V(G)$, the sets $N[v_1]\cap C$ and $N[v_2]\cap C$ are distinct and nonempty (here $N[v]$ denotes a vertex $v$ and its neighbors). We study the case when $G$ is the infinite hexagonal grid $H$. Cohen et.al. constructed two identifying codes for $H$ with density $3/7$ and proved that any identifying code for $H$ must have density at least $16/39\approx0.410256$. Both their upper and lower bounds were best known until now. Here we prove a lower bound of $12/29\approx0.413793$.

Age-dependent reliability analysis and development of a fuzzy based condition rating tool for timber utility poles

description: Timber is the most commonly used material for supporting utility power lines, with an estimated quantity of over 165 million across North America. Timber Poles provide a safe and cost effective mean to supply electricity and communication to vast majority of consumers, and are considered to be the most important asset by utility companies. Due to significantly large investment in timber poles across North America, there is need to investigate their structural reliability. Within the past few decades, different parts of the world have experienced significant climate changes. Specifically in North America, Hurricanes and strong winds have caused tremendous damage to infrastructure including Timber utility pole structures. Therefore, there is an urgent need to understand the performance of timber poles to mitigate damage during extreme climatic hazards. This research presents a fragility based methodology to assess and compare the vulnerability of timber poles exposed to wind hazards models for selected locations. Timber poles are designed as per both CSA 22.3 No.1 deterministic design wind loads and probabilistic wind loads. Wind hazard models for selected locations are developed using Extreme value analysis. Reliability of timber poles is determined through convolution of structural fragility models with the wind hazard models. Strength degradation with time due to decay was also taken into account for a holistic approach towards risk assessment of Timber poles. In addition to reliability analysis, a framework for development of a fuzzy logic based condition rating tool is also proposed in this research. Fuzzy synthetic evaluation technique, which is based on fuzzy logic theory has been utilized for the proposed framework. External decay, internal decay, wood pecker damage and mechanical damage were selected as performance indicators. A five tuple fuzzy linguistic evaluation set having levels of Very good, Good, Fair, Poor and Very Poor was used to assess the performance indicators. The proposed framework was validated through an illustrative example of ten timber poles. Analytical hierarchy process (AHP) was used to calculate weights for the four performance indicators. The proposed framework also provides the ability to prioritize timber poles according to their respective level of deterioration.

description: We investigate the leading terms of the spectral action for odd-dimensional Riemannian spin manifolds with the Dirac operator perturbed by a scalar function. We calculate first two Gilkey-de Witt coefficients and make explicit calculations for the case of $n$-spheres with a completely symmetric Dirac. In the special case of dimension 3, when such perturbation corresponds to the completely antisymmetric torsion we carry out the noncommutative calculation following Chamseddine and Connes and study the case of $SU_q(2)$.
