X-ray diffraction and raman spectroscopy of pulsed light irradiated nanocrystalline silicon
Creators: name: Patel, Bhavesh
Publisher: name: University of British Columbia
Year: 2015

description: A series of experiments is performed on a number of hydrogenated nanocrystalline silicon samples prepared through pulsed xenon light irradiation. These samples are then subjected to XRD and Raman spectroscopic analyzes. The mean crystalline size, corresponding to one of the pulsed hydrogenated nanocrystalline silicon sample, was determined from the XRD results through the use of Scherrer's equation. This yielded a mean crystallite size of 3.8 ± 1.1 nm, which is much less than that typically found in hydrogenated nanocrystalline silicon prepared through conventional means. The Raman spectra, corresponding to all of the samples, is determined using two different Raman excitation sources, 442 and 633 nm. Through a process of peak decomposition, the crystalline volume fraction is determined corresponding to each sample and each Raman excitation source. Five key observations are made from this analysis. First, it is observed that pulsing seems to enhance the crystalline volume fraction. Second, it is noted that the substrate holder temperature plays a relatively minor role, if at all, in shaping the crystalline volume fraction. Third, the crystalline volume fraction of the samples considered in this study is representative of that found in other forms hydrogenated nanocrystalline silicon. Fourth, the dependence of the crystalline volume fraction on the mean crystallite size seems to follow the general trend observed in the literature, i.e., that smaller mean crystallite sizes correspond to greater crystalline volume fractions, although further data would be required in order to confirm this trend. Fifth and finally, it is observed that the crystalline volume fractions determine from the 633 nm Raman excitation source are less than those found from the 442 nm Raman excitation source. This suggests an inhomogeneity in the material structure, with deeper materials from the surface having a reduced crystalline content. The reasons for this remain unknown at the present time. Some recommendations further study are then made.

description: We have constructed an extended composite luminosity profile for the Andromeda galaxy, M31, and have decomposed it into three basic luminous structural components: a bulge, a disk and a halo. The dust-free Spitzer/IRAC imaging and extended spatial coverage of ground-based optical imaging and deep star counts allow us to map M31's structure from its center to 22 kpc along the major axis. We apply different decomposition methods for the 1D luminosity profiles and 2D images. These include non-linear least-squares and Bayesian Monte-Carlo Markov-chain analyses. The basic photometric model for M31 has a Sersic bulge with shape index n = 2.2 +/- 0.3 and effective radius R_e = 1.0 +/- 0.2 kpc, a dust-free exponential disk of scale length R_d = 5.3 +/- 0.5 kpc; the parameter errors reflect the range between various decomposition methods. The bulge parameter, n, is rather insensitive to bandpass effects and its value suggests a first rapid formation via mergers followed by secular growth from the disk. The M31 halo has a 2D power-law index ~ -2.5 +/- 0.2. We find that the M31 bulge light is mostly dominant over the range R_minor < 1.2 kpc. The disk takes over in the range 1.2 kpc < R_minor < 9 kpc, whereas the halo dominates at R_minor > 9 kpc. The stellar nucleus, bulge, disk, and halo components each contribute roughly 0.05%, 23%, 73% and 4% of the total light of M31 out to 200 kpc along the minor axis. Nominal errors for the structural parameters of the M31 bulge, disk and halo amount to 20%. If M31 and the Milky Way are at all typical, faint stellar halos should be routinely detected in galaxy surveys reaching below mu_i ~ 27 mag/arcsec^2. We stress that our results rely on this photometric analysis alone. Structural parameters may change when other fundamental constraints, such as those provided by abundance gradients and stellar kinematics, are considered simultaneously (Abridged).

Task Scheduling in Cloud Computing Using Hybrid Meta-heuristic: A Review

description: In recent years with the advent of high bandwidth internet access availability, the cloud computing applications have boomed. With more and more applications being run over the cloud and an increase in the overall user base of the different cloud platforms, the need for highly efficient job scheduling techniques has also increased. The task of a conventional job scheduling algorithm is to determine a sequence of execution for the jobs, which uses the least resources like time, processing, memory, etc. Generally, the user requires more services and very high efficiency. An efficient scheduling technique helps in proper utilization of the resources. In this research realm, the hybrid meta-heuristic algorithms have proven to be very effective in optimizing the task scheduling by providing better cost efficiency than when singly employed. This study presents a systematic and extensive analysis of task scheduling techniques in cloud computing using the various hybrid variants of meta-heuristic methods, like Genetic Algorithm, Tabu Search, Harmony Search, Artificial Bee Colony, Particle Swarm Optimization, etc. In this research review, a separate section discusses the use of various performance evaluation metrics throughout the literature.
Measurement of structural stresses using hole drilling
Creators: name: Harrington, Joshua S.
Publisher: name: University of British Columbia
Year: 2015

description: From a measurement standpoint structural stresses can be divided into two broad categories: stresses that can be measured straightforwardly by adjusting loads, e.g., live loads on a bridge, and those that are much more difficult, e.g., gravitational loads and loads due to static indeterminacy. This research focuses on the development of a method that combines the hole-drilling technique, a method used to measure residual stresses, and digital image correlation (DIC), an optical method for determining displacements, to measure these difficult-to-measure structural stresses. The hole-drilling technique works by relating local displacements caused by the removal of a small amount of stressed material to the material stresses. Adapting the hole-drilling technique to measure structural stresses requires scaling the hole size and modifying the calculation approach to measure deeper into a material. DIC is a robust means to measure full-field displacements and unlike other methods used to measure hole-drilling displacements, can easily be scaled to different hole sizes and corrected for measurement artifacts. There are three primary areas of investigation: the modification of the calculation method to account for the finite thickness of structural members, understanding the capabilities and limitations of DIC for measuring hole-drilling displacements, and evaluating the effects hole cutting has on the measurement. Experimental measurements are made to validate the measurement method as well as apply it to the real world problem of measuring thermally induced stresses in railroad tracks.

description: Unique word OFDM is a novel technique for constructing OFDM symbols, that has many advantages over cyclic prefix OFDM. In this paper we investigate two different approaches for the generation of an OFDM symbol containing a unique word in its time domain representation. The two-step and the direct approach seem very similar at first sight, but actually produce completely different OFDM symbols. Also the overall system's bit error ratio differs significantly for the two approaches. We will prove these propositions analytically, and we will give simulation results for further illustration.

Studying dusty star-forming galaxies with Herschel-SPIRE
Creators: name: Asboth, Viktoria
Publisher: name: University of British Columbia
Year: 2015

description: Observations suggest that almost half of the total light emitted by stars in the Universe is absorbed by dust, and the emission is re-radiated at far-infrared and submillimeter wavelengths. Dusty star-forming galaxies play a significant role in the stellar mass build-up at high redshift, but their contribution to the cosmic star formation rate density at z > 4 is still unknown, due to the currently limited availability of statistically significant high-redshift dusty galaxy samples. In this thesis we analyze data from two large area surveys, the HerMES Large Mode Survey (HeLMS) and the Herschel Stripe 82 Survey (HerS), observed with the Herschel-SPIRE instrument at far-infrared wavelengths of 250, 350 and 500 μm. We describe the process of constructing maps from detector data that provide an unbiased estimate of the sky signal, then we use a map-based detection method to assemble a large catalog of candidate z > 4 dusty star-forming galaxies detected in HeLMS. The large area of the survey allows us to detect a significant number of sources and we are able to determine the differential number counts of these galaxies at 500 μm. We find an excess of such high-redshift galaxies compared to model predictions, and our counts suggest strong evolution in their properties. We examine the properties of our sources at different wavelengths. Follow-up observations with ALMA, SCUBA-2 and ACT strengthen our initial assumption that the detected population consists of high-z dusty galaxies with their spectrum dominated by thermal dust emission, best fitted with an optically thick modified blackbody. These follow-up observations also allow us to examine the biasing effects in our number counts due to blending of nearby sources. We also investigate the mean dusty star formation activity in moderate redshift massive galaxy clusters detected by the Atacama Cosmology Telescope. We find that, on average, there is an excess of far-infrared emission in the line of sight of these clusters. Finding dusty star-forming galaxies in massive clusters implies that the environment can affect the star formation activity in galaxies.

description: The classical method for deriving the macroscopic dynamics of a lattice Boltzmann system is to use a combination of different approximations and expansions. Usually a Chapman-Enskog analysis is performed, either on the continuous Boltzmann system, or its discrete velocity counterpart. Separately a discrete time approximation is introduced to the discrete velocity Boltzmann system, to achieve a practically useful approximation to the continuous system, for use in computation. Thereafter, with some additional arguments, the dynamics of the Chapman-Enskog expansion are linked to the discrete time system to produce the dynamics of the completely discrete scheme. In this paper we put forward a different route to the macroscopic dynamics. We begin with the system discrete in both velocity space and time. We hypothesize that the alternating steps of advection and relaxation, common to all lattice Boltzmann schemes, give rise to a slow invariant manifold. We perform a time step expansion of the discrete time dynamics using the invariance of the manifold. Finally we calculate the dynamics arising from this system. By choosing the fully discrete scheme as a starting point we avoid mixing approximations and arrive at a general form of the microscopic dynamics up to the second order in the time step. We calculate the macroscopic dynamics of two commonly used lattice schemes up to the first order, and hence find the precise form of the deviation from the Navier-Stokes equations in the dissipative term, arising from the discretization of velocity space. Finally we perform a short wave perturbation on the dynamics of these example systems, to find the necessary conditions for their stability.

description: The protein-polysaccharide combinations that lead to electrostatic complex and coacervates formation are the object of extensive research using both layer-by-layer and mixed emulsion approaches. The protein-polysaccharide conjugates demonstrated interesting physico-chemical properties as stabilizers and emulsifiers as well as texture modifiers in food products. Furthermore, they are potential optimal nutrient delivery systems. Their complex behavior due to several factors such as pH, ionic strength, concentration, heat, and mechanical treatments is the main reason behind the continuous growth of the research field. The review is reporting same recent advances on the topic, along with an overview on the possible interactions between protein and polysaccharide, from Maillard reaction to enzymatic crosslinking passing through coacervates.

description: We consider a non-equilibrium three-state model whose dynamics is Markovian and displays the same symmetry as the three-state Potts model, i.e., the transition rates are invariant under the permutation of the states. Unlike the Potts model, detailed balance is in general not satisfied. The aging and the stationary properties of the model defined on a square lattice are obtained by means of large-scale Monte Carlo simulations. We show that the phase diagram presents a critical line, belonging to the three-state Potts universality class, that ends at a point whose universality class is that of the voter model. Aging is considered on the critical line, at the voter point and in the ferromagnetic phase.

description: The generalized Gerasimov-Drell-Hearn (GDH) sum rule is known to be very sensitive to QCD radiative and power corrections. We improve the previously developed QCD-inspired model for the $Q^2$-dependence of the GDH sum rule. We take into account higher order radiative and higher twist power corrections extracted from precise Jefferson Lab data on the lowest moment of the spin-dependent proton structure function $Γ_1^{p}(Q^2)$ and on the Bjorken sum rule $Γ_1^{p-n}(Q^2)$. By using the singularity-free analytic perturbation theory we demonstrate that the matching point between chiral-like positive-$Q^2$ expansion and QCD operator product $1/Q^2$-expansion for the nucleon spin sum rules can be shifted down to rather low $Q\simeqΛ_{QCD}$ leading to a good description of recent proton, neutron, deuteron and Bjorken sum rule data at all accessible $Q^2$.

Impact of coal-carrying trains on particulate matter concentrations in the Lower Mainland region of British Columbia, Canada
Creators: name: Akaoka, Kevin J.
Publisher: name: University of British Columbia
Year: 2015

description: The transport of coal by train through residential neighbourhoods in Metro Vancouver, British Columbia, Canada is a growing concern for many residents living near the railway. This study aimed to identify and quantify any potential particulate matter (PM) increase caused by the presence of rail traffic adjacent to John Oliver Park in Delta, BC. Field work was carried out during August and September 2014, using a GRIMM optical particle counter that measured PM concentration at various size ranges. A select number of passing trains were confirmed visually, while the majority of passages were identified with audio data recorded by a microphone. A horizontally operating mini-micropulse lidar system was also set up at the park on three individual days to make intensive backscatter measurements. Wind data were recorded by collocated instruments maintained by Metro Vancouver. Finally, the Corporation of Delta had a dustfall measurement campaign during the same time period. Trains carrying coal are associated with a 5.28, 4.11, and 2.55 µg/m³ average increase in concentration over a 15 minute period, compared to control conditions for PM₃, PM₁₀, and PM₂₀, respectively. These increases are all statistically significant at α=0.01. PM concentrations during train passages of all types were not found to be significantly different from PM concentrations during control conditions. The presence of coal dust particles at the site was confirmed by the dustfall measurements carried out by the Corporation of Delta. Lidar backscatter imagery provided individual snapshots of train passages. However, it is clear that not every train passage causes an increase in PM concentration, and the effect appears to be highly dependent on wind direction and local meteorology.
Lambda(1405) and kaonic few-body states in chiral dynamics

description: The present status of the Lambda(1405) structure study in chiral dynamics is briefly reviewed. It turns out that the Lambda(1405) resonance can be described by hadronic dynamics. The idea of the hadronic molecular state is extended to kaonic few-body states. It is concluded that, due to the fact that K and N have similar coupling nature in s-wave Kbar couplings, there are few-body quasibound states with kaons systematically just below the break-up thresholds, like KbarNN, KbarKN and KbarKK, as well as Lambda(1405) as a KbarN quasibound state and f_0(980) and a_0(980) as KbarK.

Studies on the structure and composition of the outer membrane of Caulobacter crescentus
Creators: name: Jones, Michael D.
Publisher: name: University of British Columbia
Year: 2015

description: Classically, outer membranes are half lipid, half protein, and the outmost layers of Gram- negative bacteria. For Caulobacter crescentus the outer membrane is the penultimate layer beneath a protein surface layer (S-layer). The S-layer of the caulobacter cell envelope is an exciting platform for high density peptide display and biotechnology development. We focused on elucidating the structure of the outer membrane by crystallizing the S-layer protein, RsaA; solving the structure of the the lipopolysaccharide; and characterizing a newly discovered porin, OmpW. S-layer proteins are highly resistant to crystallization, because wo-dimensional S-layer formation out competes three-dimensional crystal formation. To achieve a crystallisable form of RsaA, a C-terminal truncation version was constructed and expressed in the native host, C. crescentus. The secreted protein was prone to aggregation, so low agitation and slow concentration protocols had to be developed. The RsaA truncate produced large crystals that diffracted to <2.5 Å. Solving the phases proved to be a serious hurdle and the final protein structure remains unsolved. The lipopolysaccharide of C. crescentus is the anchor that supports the S-layer. The structure of the lipid A portion was solved previously but structures for the core oligosaccharide and the O-polysaccharide had not been deduced. In collaboration with Dr. Evgeny Vinogradov, these remaining structures were solved. The core oligosaccharide has a branched heptasaccharide structure. The O-polysaccharide is a heptasaccharide containing the dideoxy sugar N-acetylperosamine. Additionally, a rhamnan polysaccharide was discovered and its structure was determined. Porins, non-specific passive protein channels, are significant components of classical Gram-negative outer membranes. Despite this, no porin had ever been identified in C. crescentus. We report the identification and characterization of the porin OmpW in C. crescentus. OmpW has low conductance of 125 pSv in 1 M KCl. That is interesting because homologous porins in other bacteria have no detectable pore-forming activity. The cell envelopes of bacteria are remarkable structures; the work here illuminates the unique structures present in the caulobacter envelope.

UV-LED photo-activated metal oxide semiconductors for gas sensing application : fabrication and performance evaluation
Creators: name: Espid, Ehsan
Publisher: name: University of British Columbia
Year: 2016

description: The idea of functionalizing chemical gas sensors at room temperature as well as making them smaller and more efficient has initiated important progresses in the last few years among scientists worldwide. Ultraviolet Light Emitting Diode (UV-LED) technology has shown its capability to fulfill the gap between laboratorial and industrial production of room temperature gas sensors. In this research, a review on the performances, preparation techniques, and most influential factors of several photo-activated metal oxide semiconductor gas sensors under UV-LED irradiation was conducted. Further, a comparative study on the development of sensitive gas sensors using ZnO and In₂O₃ semiconductors for NO₂ gas detection was performed. The results indicated that the sensitivity of In₂O₃ to NO₂ is approximately two times greater than that of ZnO for all the experimented irradiances. The highest sensitivities with complete recovery for the ZnO and In₂O₃ based sensors were obtained at 1.2 mW/cm² and 2.8 mW/cm² irradiances, respectively. In general, the In₂O₃ sensors required a higher UV irradiance compared to ZnO sensors, to prevent permanent adsorption of target gas molecules on the surface. To further increase the sensitivity and reduce the response time, n-type semiconductor oxides of ZnO and In₂O₃ were coupled using co-precipitation method, to obtain nano-crystalline composite sensing materials. The composition, structure and optical properties of the prepared samples were characterized by EDS, XRD, SEM, XPS and UV-Vis analyses. The composite materials showed higher sensitivity towards NO₂ with a 200s decrease in response time compared to pristine samples. A favorable composition ratio of [In]:[Zn] was determined to be 1:2 for the nano-composite particles, with 2.21 sensitivity as the highest sensing performance to 5 ppm NO₂. The high sensitivity of this combination is attributed to the morphology and composite porous structure, as well as lower band-gap of the target composite. The irradiance of 1.7 mW/cm² provided the highest sensitivity, short response time and a complete recovery for the ZnO/In₂O₃ composite structures, within the experimented range. It’s believed that, ZnO favors the flow of charge carriers and increases the surface area, while In₂O₃ acts as active light absorption centers and enhances chemisorption ability in the composite.

description: Convergent beam electron diffraction (CBED) performed on two-dimensional (2D) materials recently emerged as a powerful tool to study structural and stacking defects, adsorbates, atomic 3D displacements in the layers, and the interlayer distances. The formation of the interference patterns in individual CBED spots of 2D crystals can be considered as a hologram, thus the CBED patterns can be directly reconstructed by conventional reconstruction methods adapted from holography. In this study, we review recent results applying CBED to 2D crystals and their heterostructures: holographic CBED on bilayers with the reconstruction of defects and the determination of interlayer distance, CBED on 2D crystal monolayers to reveal adsorbates, and CBED on multilayered van der Waals systems with moiré patterns for local structural determination.

description: Active galactic nuclei (AGN), powered by long-term accretion onto central supermassive black holes, produce relativistic jets with lifetimes of greater than one million yr that preclude observations at birth. Transient accretion onto a supermassive black hole, for example through the tidal disruption of a stray star, may therefore offer a unique opportunity to observe and study the birth of a relativistic jet. On 2011 March 25, the Swift γ-ray satellite discovered an unusual transient source (Swift J164449.3+573451) potentially representing such an event. Here we present the discovery of a luminous radio transient associated with Swift J164449.3+573451, and an extensive set of observations spanning centimeter to millimeter wavelengths and covering the first month of evolution. These observations lead to a positional coincidence with the nucleus of an inactive galaxy, and provide direct evidence for a newly-formed relativistic outflow, launched by transient accretion onto a million solar mass black hole. While a relativistic outflow was not predicted in this scenario, we show that the tidal disruption of a star naturally explains the high-energy properties, radio luminosity, and the inferred rate of such events. The weaker beaming in the radio compared to γ-rays/X-rays, suggests that radio searches may uncover similar events out to redshifts of z ~ 6.

Comparative studies of the oxidation of MoSi₂ based materials

description: Molybdenum disilicide (MoSi₂) is a promising intermetallic material for high temperature applications (above 1000°C). However, it rapidly oxidizes at temperatures ranging from 400 to 600°C, which given enough time, can lead to its disintegration. Above 1000°C, MoSi₂ exhibits better oxidation resistance due to the formation of a continuous SiO₂ layer (or alumina layer for the materials doped with aluminum). The experiments in this study were divided into two main categories: low temperature oxidation (300 to 900°C; high oxidation rate expected) and high temperature oxidation (1000 to 1600°C; lower oxidation rate expected due to rapid formation of the protective oxide films). The isothermal exposure time in the low temperature oxidation experiments was from 4 to 240 hrs while it was from 2 to 144 hrs for the high temperature oxidation experiments. Five different, commercially available, MoSi₂ based heating elements, i.e. Kanthal Super (labelled by the manufacturer as KS-1700, KS-1800, KS-1900, KS-ER and KS-HT) were used in the experiments. It was found that the oxidation behavior of different materials under investigation depended strongly on their chemical and phase composition, exposure time and temperature. KS-ER and KS-1800 showed excellent resistance against the low temperature (300 to 900°C) degradation for up to 240 hrs, while KS-HT and KS-1900 underwent significant degradation after 240 hrs of air exposure within the same temperature range. In high temperature oxidation experiments, a dense barrier alumina film (1.5 µm thick at 1000°C to 50 µm thick at 1500°C for up to 144 hrs) formed on KS-ER samples. A dense glassy SiO₂ film (3 µm thick at 1000°C to 50 µm thick at 1600°C for up to 144 hrs) formed on the other types of samples. The glass scale on the surface of KS-1700, KS-1800 and KS-HT was significantly thicker (~3 times) than that on KS-HT over the temperature range of 1200°C to 1600°C after 144 hrs. The rate of alumina formation of KS-ER was relatively higher than the glass film formation of the other types of composite MoSi₂ materials. The differences in the oxidation behavior of various MoSi₂-based materials were linked to their chemistry and phase compositions.

Gender-specific Call of Duty: A Note on the Neglect of Conscription in Gender Equality Indices

description: We document that existing gender equality indices do not account for gender-specific mandatory peace-time conscription (compulsory military service). This suggests that gender-specific conscription is not considered to be an important gender issue. If an indicator measuring the gender equality of mandatory conscription was to be included in gender equality indices with appropriate weight, then the relative rankings of countries in terms of measured gender equality could be affected. In the context of the Nordic countries, this would mean that Finland and Denmark - the countries with mandatory conscription for men only - would have worse scores with respect to gender equality compared to Sweden and Norway, countries with conscription for both men and women - and Iceland, which has no mandatory conscription, regardless of gender.

description: We present Hi spectral line and radio-continuum VLA data of the galaxy NGC 765, complemented by optical and Chandra X-ray maps. NGC 765 has the largest Hi-to-optical ratio known to date of any spiral galaxy and one of the largest known Hi discs in absolute size with a diameter of 240 kpc measured at a surface density of 2e19 atoms/cm^2. We derive a total Hi mass of M_HI = 4.7e10 Msun, a dynamical mass of Mdyn - 5.1e11 Msun and an Hi mass to luminosity ratio of M_HI/L_B = 1.6, making it the nearest and largest "crouching giant". Optical images reveal evidence of a central bar with tightly wound low-surface brightness spiral arms extending from it. Radio-continuum (L_1.4 GHz = 1.3e21 W/Hz) and X-ray (L_X ~ 1.7e40 erg/s) emission is found to coincide with the optical core of the galaxy, compatible with nuclear activity powered by a low-luminosity AGN. We may be dealing with a galaxy that has retained in its current morphology traces of its formation history. In fact, it may still be undergoing some accretion, as evidenced by the presence of Hi clumps the size < 10 kpc and mass (10e8-10e9 Msun) of small (dIrr) galaxies in the outskirts of its Hi disc and by the presence of two similarly sized companions.

description: We report the results of the first transit timing variation (TTV) analysis of the very hot Jupiter OGLE-TR-132b, using ten transits collected over a seven-year period. Our analysis combines three previously published transit light curves with seven new transits, which were observed between February 2008 and May 2009 with the new MagIC-e2V instrument on the Magellan Telescopes in Chile. We provide a revised planetary radius of R_p = 1.23+/-0.07 R_J, which is slightly larger than, but consistent within the errors, of the previously published results. Analysis of the planet-to-star radius ratio, orbital separation, inclination and transit duration reveals no apparent variation in any of those parameters during the time span observed. We also find no sign of transit timing variations larger than -108+/-49 s, with most residuals very close to zero. This allows us to place an upper limit of 5-10 M_Earth for a coplanar, low-eccentricity perturber in either the 2:1 or 3:2 mean-motion resonance with OGLE-TR-132b. We similarly find that the data are entirely consistent with a constant orbital period and there is no evidence for orbital decay within the limits of precision of our data.
