description: This task will use outputs from the Copernicus Marine Environment Monitoring Service (CMEMS) to develop a system for ship routing hazard mapping. Starting from knowledge of the environmental fields affecting vessel seakeeping, the system will estimate hazard and cost associated to known routes in the Atlantic Ocean. The system will employ model analysis or reanalysis of sea state (wave height, period, and direction), hydrodynamics (near surface ocean currents), and meteorological (wind) models. The system will produce an objective route hazard assessment, based on UNIBO experience in hazard mapping and probabilistic approaches. The investigated routes will be selected based on the most relevant ones, according to the AIS (Automatic Information System) density maps. In particular, the existing CMCC ship routing code (VISIR) will be first of all validated through inter-comparison with analytical benchmarks and other published models.  VISIR's functionalities will then be extended for optimizing the operational costs (bunker) of large ocean-going vessels sailing along routes compliant with IMO safety recommendations. The same approach will be extended to computation of vessel operational costs along the route. This information will build up a database, queried by the end-?user through a graphical interface for visualizing customized maps of route hazard and cost for user provided parameters [D8.10]. The fitness of AtlantOS for ship routing will be analyzed with a dedicated report [D8.14].

description: Despite the substantial efforts of governments in promoting sustainable development, there exists considerable debate regarding the environmental policy making approach under information ambiguity and competition. This study investigates market competition between a green and a non-green supply chain (SC) under two government regulation policies, namely, selling price and production quantities. To tackle the policy making challenges, a fuzzy game theoretical model was employed in a centralized and decentralized SC setting. The results revealed that SCs always achieve a higher expected profit under a decentralized structure, regardless of the type of the governments intervention policy. Also, the government’s policy making success was found to be highly dependent on the channel leadership, market competition, and the SC structure. Our findings suggest that the policy makers’ objectives in reducing environmental pollution and increasing revenue are highly achievable, without risk of losing channel coordination and maximum level of efficiency.

description: The effect of Co on the structural, magnetic and magnetocaloric effect (MCE) of Ni50-xCoxMn38Sb12 (x=0,2,3,4,5) Heusler alloys was studied. Using x-ray diffraction, we show the evolution of the martensitic phase from the austenite phase. The martensitic transition temperature is found to decrease monotonically with Co concentration. Remarkable enhancement of MCE is observed near room temperature upon Co substitution. The maximum magnetic entropy change of 34 Jkg-1K-1 was achieved in x=5 at 262 K in a field of 50 kOe and a value of 29 Jkg-1K-1 found near room temperature. The significant increase in the magnetization associated with the reverse martensitic transition is responsible for the giant MCE in these compounds.

Growth optimization of Synechococcus sp. PCC7002 in laboratory photobioreactors
Creators: name: Wu, Tong
Publisher: name: University of British Columbia
Year: 2014

description: Microalgae have the potential to be a significant source of renewable energy. Microalgae reduce CO₂ emissions by consuming it via photosynthesis, and provide a cheap option to produce high value biological products. Synechococcus sp. PCC7002 is a microalga strain that possesses all of these potentials, and can be easily genetically modified. To utilize these potentials of Synechococcus sp. PCC7002, a method to optimize its growth in terms of a high biomass concentration and a high growth rate needs to be implemented. To achieve this objective, shake flask scale experiments, as well as reactor scale experiments were designed and conducted. 250 mL shake flasks with 100 mL of medium were used for the flask experiments. In the first experiment, the A+ medium was investigated. The optimal concentrations of the three important nutrient components, NaNO₃, FeCl₃, and KH₂PO₄ to achieve highest Xmax were determined to be 23.5 mM, 0.028 mM, and 0.72 mM respectively. The optimal concentrations to achieve highest µmax were 5.88 mM, 0.007 mM, and 0.18 mM respectively. Another factorial experiment regarding the effects of temperature and light intensity was carried out next. The optimal conditions within the tested range were determined to be 35˚C, 250µE/m²/s for maximum biomass concentration, and 35˚C, 150 µE/m²/s for maximum specific growth rate. The effects of inlet CO₂ concentrations were studied in the large scale continuously aerated reactor. The optimal concentration of CO₂ was found to be 8% by volume, and 3.1 g/L biomass concentration and 0.0186 hr-¹ maximum specific growth rate were achieved under this condition. Further increase in inlet CO₂ concentration led to a decrease in biomass concentration due to the lower pH associated with the higher carbonic acid concentration in the medium. Lastly, an experiment was completed using the recombinant strain, with a very good growth rate obtained at 33˚C, 300 µE/m²/s, and 0.5 L/min inlet gas with 10% CO₂. Under this condition, a maximum biomass concentration of 3.1 g/L, and a maximum specific growth rate of 0.0180 hr-¹ were achieved.

description: Previous work has shown that training the neural networks for bottle neck feature extraction in a multilingual way can lead to improvements in word error rate and average term weighted value in a telephone key word search task. In this work we conduct a systematic study on a) which multilingual training strategy to employ, b) the effect of language selection and amount of multilingual training data used and c) how to find a suitable combination for languages. We conducted our experiment on the key word search task and the languages of the IARPA BABEL program. In a first step, we assessed the performance of a single language out of all available languages in combination with the target language. Based on these results, we then combined a multitude of languages. We also examined the influence of the amount of training data per language, as well as different techniques for combining the languages during network training. Our experiments show that data from arbitrary additional languages does not necessarily increase the performance of a system. But when combining a suitable set of languages, a significant gain in performance can be achieved.

description: We consider the non-relativistic Hartree model in the gravitational case, i.e. with attractive Coulomb-Newton interaction. For a given mass, we construct stationary states with non-zero temperature by minimizing the corresponding free energy functional. It is proved that minimizers exist if and only if the temperature of the system is below a certain threshold(possibly infinite), which itself depends on the specific choice of the entropy functional. We also investigate whether the corresponding minimizers are mixed or pure quantum states and characterize a positive critical temperature above which mixed states appear.
Onset of "ridge phenomenon" in AA and pp collisions and percolation string model

description: Detailed study of centrality dependence of low-p_t manifestation of so-called "near-side ridge" phenomenon is reported recently by STAR for all charged hadrons with p_t>0.15 GeV/c from AuAu collisions at 62 and 200 GeV at RHIC[1]. It is indicating the existence of the energy-dependent centrality point where some sudden changes in the correlation pattern are observed. In the present work we use the hypothesis of string percolation phase transition for the description of the onset of this ridge. One may assume that the formation of rather large "macroscopic" clusters composed of several overlapped strings extended in rapidity and localized in azimuth could be one of the possible processes leading to the observed phenomenon. This onset is characterized by some definite ("critical") number of participating nucleons. We use also another physical quantity, transverse particle density, to characterize this threshold behavior, this variable brings the transition points for two energies to coincidence [1]. So parameters of the percolation model are defined at these critical points. Also we use results of our previous calculations[2] for energy of collision 17.3 GeV based on observed threshold of anomalous suppression of J/psi. Obtained parameters are extrapolated to AA and pp collisions for energies over the range 17.3 GeV - 7000 GeV.

description: A detailed derivation of the Lattice Boltzmann (LB) scheme for relativistic fluids recently proposed in Ref. [1], is presented. The method is numerically validated and applied to the case of two quite different relativistic fluid dynamic problems, namely shock-wave propagation in quark-gluon plasmas and the impact of a supernova blast-wave on massive interstellar clouds. Close to second order convergence with the grid resolution, as well as linear dependence of computational time on the number of grid points and time-steps, are reported.

System support for elasticity and high availability
Creators: name: Rajagopalan, Shriram
Publisher: name: University of British Columbia
Year: 2014

description: Elasticity and high availability (HA) are key requirements among modern Internet applications. Elasticity enables applications to dynamically allocate/release physical resources in proportion to request load. High availability enables applications to mask failures in the system from end users. In current practice, every application implements these features as part of its own application logic, resulting in unnecessary design complexity. This thesis argues that facilities for elasticity and HA should be exposed as system-level primitives, in the same way abstractions for files and networks became operating system-level primitives three decades ago. Unfortunately, providing these higher-level services efficiently may require knowledge of application data structures, consistency requirements, and workloads. This thesis describes initial instantiations of such interfaces for two broad (and different) classes of applications: network middleboxes (e.g., load balancers, intrusion prevention systems, etc) and database systems. Elasticity is achieved typically through dynamic partitioning of state and inputs into independent subsets, while HA is achieved through state replication. Guided by this principle, this thesis presents a system-level runtime that partitions the middlebox state along flow boundaries and provides abstractions for elasticity and HA using live migration and replication of flows respectively. For database systems, this thesis presents a hypervisor-level HA system that performs database-aware virtual machine replication, eliminating the need for complex application-level HA mechanisms. This thesis concludes that while there may not be a one-size-fits-all solution to application elasticity and HA, it is still feasible and beneficial to provide system-level primitives that are applicable across one or more application domains.

description: We present the first detailed phase-resolved spectral analysis of a joint Chandra High Energy Transmission Grating Spectrometer and Rossi X-ray Timing Explorer observation of the rho variability class in the microquasar GRS 1915+105. The rho cycle displays a high-amplitude, double-peaked flare that recurs roughly every 50 s, and is sometimes referred to as the "heartbeat" oscillation. The spectral and timing properties of the oscillation are consistent with the radiation pressure instability and the evolution of a local Eddington limit in the inner disk. We exploit strong variations in the X-ray continuum, iron emission lines, and the accretion disk wind to probe the accretion geometry over nearly six orders of magnitude in distance from the black hole. At small scales (1-10 R_g), we detect a burst of bremsstrahlung emission that appears to occur when a portion of the inner accretion disk evaporates due to radiation pressure. Jet activity, as inferred from the appearance of a short X-ray hard state, seems to be limited to times near minimum luminosity, with a duty cycle of ~10%. On larger scales (1e5-1e6 R_g) we use detailed photoionization arguments to track the relationship between the fast X-ray variability and the accretion disk wind. For the first time, we are able to show that changes in the broadband X-ray spectrum produce changes in the structure and density of the accretion disk wind on timescales as short as 5 seconds. These results clearly establish a causal link between the X-ray oscillations and the disk wind and therefore support the existence of a disk-jet-wind connection. Furthermore, our analysis shows that the mass loss rate in the wind may be sufficient to cause long-term oscillations in the accretion rate, leading to state transitions in GRS 1915+105.

description: We study the environmental dependence of stellar population properties at z ~ 1.3. We derive galaxy properties (stellar masses, ages and star formation histories) for samples of massive, red, passive early-type galaxies in two high-redshift clusters, RXJ0849+4452 and RXJ0848+4453 (with redshifts of z = 1.26 and 1.27, respectively), and compare them with those measured for the RDCS1252.9-2927 cluster at z=1.24 and with those measured for a similarly mass-selected sample of field contemporaries drawn from the GOODS-South Field. Robust estimates of the aforementioned parameters have been obtained by comparing a large grid of composite stellar population models with extensive 8-10 band photometric coverage, from the rest-frame far-ultraviolet to the infrared. We find no variations of the overall stellar population properties among the different samples of cluster early-type galaxies. However, when comparing cluster versus field stellar population properties we find that, even if the (star formation weighted) ages are similar and depend only on galaxy mass, the ones in the field do employ longer timescales to assemble their final mass. We find that, approximately 1 Gyr after the onset of star formation, the majority (75%) of cluster galaxies have already assembled most (> 80%) of their final mass, while, by the same time, fewer (35%) field ETGs have. Thus we conclude that while galaxy mass regulates the timing of galaxy formation, the environment regulates the timescale of their star formation histories.

We show that it may be decomposed as a sum of two bounded measures multiplied by explicit distributions depending only on the local properties of the modular form at p. We use this decomposition to prove results on the zeros of the p-adic L-function, and we show that our results match the behaviour observed in examples calculated by Pollack and Stevens.

description: Extended narrow-line regions (ENLRs) and extended emission-line regions (EELRs) have been the focus of integral field spectroscopy aiming at the inner kiloparsecs of nearby Seyfert galaxies as well as the larger environment of high redshift QSOs. Based on observations with the Wide Field Spectrograph WiFeS at the 2.3 m telescope of the Australian National University, we present spatially resolved emission-line diagnostics of the bright Seyfert 1.5 galaxy HE 2211-3903 which is drawn from a sample of the brightest Seyfert galaxies at z<0.06 with luminosities around the classical Seyfert/QSO demarcation. In addition to the previously known spiral arms of HE 2211-3903, the emission-line maps reveal a large scale ring with a radius of about 6 kpc which is connected to the active galactic nucleus (AGN) through a bar-like structure. The overall gas kinematics indicates a disk rotation pattern. The emission-line ratios show Seyfert-type, HII region-type, and composite classifications, while there is no strong evidence of LINER-type ratios. Shock ionization is likely to be negligible throughout the galaxy. The composite line ratios are explained via a mixing line between AGN and HII region photoionization. Composite line ratios are predominantly found in between the HII regions in the circum-nuclear region, the bar-like structure to the east of the nucleus, and the eastern half of the ring, suggesting AGN photoionization of the low-density interstellar medium in an ENLR on galaxy scales. The line ratios in the nucleus indicate N-enrichment, which is discussed in terms of chemical enrichment by Wolf-Rayet and Asymptotic Giant Branch stars during past and ongoing nuclear starburst activity.

Dimensional modification of vertically aligned carbon nanotubes using miniaturized arc and glow discharges
Creators: name: Sarwar, Mirza Saquib Us
Publisher: name: University of British Columbia
Year: 2016

description: There has been a significant rise in interest in carbon nanotube (CNT) structures to be implemented in micro electro mechanical systems (MEMS) devices owing to the appealing characteristics possessed by CNTs. Electrical discharges may be used to modify and machine CNT forests generating a myriad of applications from the treated structures. High current density arc discharge may be used to machine the CNT forest and generate micro structures while low current density glow discharge may be used to treat the CNT surface and change its characteristics for relevant applications. Techniques for fabricating CNT based MEMS are being developed for some time owing to the escalating demand, and have seen substantial progress over the years. The goal is to develop a technique that can provide precise machining with high throughput, and being economically feasible at the same time. This process employs an array of Cu electrodes microfabricated through an advanced UV-LIGA process enabled with a new photoresist system in combination with electroplating, providing a low-cost path to constructing high-density arrays of µEDM electrodes for high-throughput parallel processing. The fabricated arrays of 85-µm-tall electrodes are utilized to demonstrate and characterize planar dry µEDM for post-growth patterning of CNT forests in air. Die sinking and scanning processes are tested to show pattern transfers with a 4 µm tolerance and an average surface roughness of 230 nm. An elemental analysis suggests that contamination of the electrode material on the produced patterns is minimal. Key characteristics in the use of planar electrodes for batch processing of CNT forests are revealed through experimental analysis and discussed in detail. The results suggest that the investigated process is a promising approach toward offering a cost-effective manufacturing technology for future products functionalized with custom-designed microstrucutres of CNT forests. In addition to selectively manipulating the height of the CNT iii forest to generate desired structures for MEMS devices, research is conducted to modify the diameter of the nanotubes locally by means of glow discharge to attain further characteristic enhancements derived from such modified CNTs. Literature exists where CNTs have been treated by plasma (mostly for functionalization), but local treatment is a novel approach. The outcome of the research has given rise to results similar to literature where the diameter is decreased by rupturing of outer walls of MWCNT. In addition, extension of the research has resulted in coalesced structures that are reported for the first time. Further extension of the research to radio frequency discharge has been proposed and designed. It is postulated that such local configuration of characteristic parameters of CNT forest surface can have a number of applications in MEMS, electronics, and other possible fields.

description: Graphene subject to a spatially uniform, circularly-polarized electric field supports a Floquet spectrum with properties akin to those of a topological insulator, including non-vanishing Chern numbers associated with bulk bands and current-carrying edge states. Transport properties of this system however are complicated by the non-equilibrium occupations of the Floquet states. We address this by considering transport in a two-terminal ribbon geometry for which the leads have well-defined chemical potentials, with an irradiated central scattering region. We demonstrate the presence of edge states, which for infinite mass boundary conditions may be associated with only one of the two valleys. At low frequencies, the bulk DC conductivity near zero energy is shown to be dominated by a series of states with very narrow anticrossings, leading to super-diffusive behavior. For very long ribbons, a ballistic regime emerges in which edge state transport dominates.

description: People are constantly on the move and in consistent need of communication. Mobile devices and internet connectivity have now become an integral part of our way of living. To best accommodate the moving person, mobiles need to switch between available networks in an attempt to avoid a break in connection. In an effort to minimise a break in connection and optimise handover, an improved location-based handover algorithm can be developed, taking advantage of cheaper, faster internet and modern day mobile processing. Such a system could map wireless networks and upload data to a server from users as they travel throughout their day to day life. This data may then be processed into an optimised model that can be downloaded as a user passes through an area, improving upon the decisions made by the algorithm. The benefits that could be gained out of mapping networks are currently not known and modern day technology may or may not be suitable to collect high-quality data necessary to produce an accurate model. This leads to the primary focus of this project which is to determine the quality of data that can be collected from a mobile device and how a model produced using this data could benefit the algorithm. Through the development of a system which mirrors its data collection capabilities, the merits of the collected data is analysed to determine the feasibility and benefits the development of this improved location-based handover algorithm. In this project, it is discovered that the data may not be of high enough quality, yet particular situations were found to be potentially beneficial to the algorithm.

description: Jet quenching is one of the major discoveries of the heavy-ion program at RHIC. While there is a wealth of data from RHIC that will soon be supplemented with measurements at the LHC, on the theoretical side the situation is less clear. A thorough understanding of jet quenching is, however, beneficial, as it is expected that medium-induced modifications of jets allow one to characterise properties of the QCD matter produced in heavy ion collisions. This talk aims at summarising the main ideas and concepts of the currently available Monte Carlo models for jet quenching.

description: Challenges in assessing and improving the duration of fertility (DF) within breeding programs have been posed due to its complex nature and genetic variability. The study aims to identify effective indicators and genes involved in DF in chickens. For this purpose, three lines of 900 Chinese Xinhua chickens were compared using seven phenotypic trait indicators (DN, FN, EFD, MCF, FR1, FR2, and FR3). The repeatability was compared to determine the best trait indicator. Differentially expressed proteins were determined by comparing high and low DF groups. Subsequently, key genes were determined using the degree method of CytoHuba and validated by bioinformatic analysis (PPI, GO, KEGG) with previously published genes and gene expression analysis. Results revealed that FN and MCF are the most repeatable among the seven indicators. The differential protein analysis identified 231 proteins; 144 were down-regulated, and 87 were up-regulated. HSPA4, GFM1, KRAS, RPL5, and RPS6 were identified as key candidate genes, working collaboratively with previously published genes in 21 significant pathways (P < 0.05). The GnRH signaling pathway, calcium signaling pathway, mTOR signaling pathway, tight junction, autophagy – animal, and ribosome pathway play an important role in long DF. Gene expression analysis showed significant differential expression (P < 0.05) of KRAS, RPL5, and HSPA4 genes between high and low DF groups. In conclusion, this study identified FN and MCF as effective indicators for addressing DF. It also identifies key candidate genes and pathways responsible for DF, which may help for future understanding of DF in chickens.

description: In dense neutron matter under the presence of a strong magnetic field, considered in the model with the Skyrme effective interaction, there are possible two types of spin ordered states. In one of them the majority of neutron spins are aligned opposite to magnetic field (thermodynamically preferable state), and in other one the majority of spins are aligned along the field (metastable state). The equation of state, incompressibility modulus and velocity of sound are determined in each case with the aim to find the peculiarities allowing to distinguish between two spin ordered phases.

description: We study the electron-proton temperature equilibration behind several shocks of the RCW 86 supernova remnant. To measure the proton temperature, we use published and new optical spectra, all from different locations on the remnant. For each location, we determine the electron temperature from X-ray spectra, and correct for temperature equilibration between the shock front and the location of the X-ray spectrum. We confirm the result of previous studies that the electron and proton temperatures behind shock fronts are consistent with equilibration for slow shocks and deviate for faster shocks. However, we can not confirm the previously reported trend of the electron temperature to proton temperature ratio of 1/v^2.

description: We present a first-principles method for calculating the charging energy of a molecular single-electron transistor operating in the Coulomb blockade regime. The properties of the molecule are modeled using density-functional theory, the environment is described by a continuum model, and the interaction between the molecule and the environment are included through the Poisson equation. The model is used to calculate the charge stability diagrams of a benzene and C$_{60}$ molecular single-electron transistor.

description: We present numerical calculations of quantum transport in perfect octagonal approximants. These calculations include a Boltzmann (intra-band) contribution and a non-Boltzmann (inter-band) contribution. When the unit cell size of the approximant increases, the magnitude of Boltzmann terms decreases, whereas the magnitude of non-Boltzmann terms increases. It shows that, in large approximants, the non-Boltzmann contributions should dominate the transport properties of electrons. This confirms the break-down of the Bloch-Boltzmann theory to understand the transport properties in approximants with very large unit cells, and then in quasicrystals, as found in actual Al-based approximants.

description: We apply mid-infrared spectro-interferometry to the massive young stellar object CRL2136. The observations were performed with the Very Large Telescope Interferometer and the MIDI instrument at a 42m baseline probing angular scales of 50 milli-arcseconds. We model the observed visibilities in parallel with diffraction-limited images at both 24.5micron and in the N-band (with resolutions of 0.6" and 0.3", respectively), as well as the spectral energy distribution. The arcsec-scale spatial information reveals the well-resolved emission from the dusty envelope. By simultaneously modelling the spatial and spectral data, we find that the bulk of the dust emission occurs at several dust sublimation radii (approximately 170 AU). This reproduces the high mid-infrared fluxes and at the same time the low visibilities observed in the MIDI data for wavelengths longward of 8.5micron. However, shortward of this wavelength the visibility data show a sharp up-turn indicative of compact emission. We discuss various potential sources of this emission. We exclude a dust disk being responsible for the observed spectral imprint on the visibilities. A cool supergiant star and an accretion disk are considered and both shown to be viable origins of the compact mid-infrared emission. We propose that CRL2136 is embedded in a dusty envelope, which truncates at several times the dust sublimation radius. A dust torus is manifest in the equatorial region. We find that the spectro-interferometric N-band signal can be reproduced by either a gaseous disk or a bloated central star. If the disk extends to the stellar surface, it accretes at a rate of 3.0 10^(-3) Msun/yr.

description: Obtaining an implementation of a data warehouse is a complex task that forces designers to acquire wide knowledge of the domain, thus requiring a high level of expertise and becoming it a prone-to-fail task. Based on our experience, we have detected a set of situations we have faced up with in real-world projects in which we believe that the use of ontologies will improve several aspects of the design of data warehouses. The aim of this article is to describe several shortcomings of current data warehouse design approaches and discuss the benefit of using ontologies to overcome them. This work is a starting point for discussing the convenience of using ontologies in data warehouse design.

description: Magnetic nanomaterials (23-43 nm) of Cu$_x$Co$_{1-x}$Fe$_2$O$_4$\ (x = 0.0, 0.5 and 1.0) were synthesized by auto combustion method. The crystallite sizes of these materials were calculated from X-ray diffraction peaks. The band observed in Fourier transform infrared spectrum near 575 cm$^{-1}$ in these samples confirm the presence of ferrite phase. Conductivity measurement shows the thermal hysteresis and demonstrates the knee points at 475$^o$C, 525$^o$C and 500$^o$C for copper ferrite, cobalt ferrite and copper-cobalt mixed ferrite respectively. The hystersis M-H loops for these materials were traced using the Vibrating Sample Magnetometer (VSM) and indicate a significant increase in the saturation magnetization (M$_s$) and remanence (M$_r$) due to the substitution of Cu$^{2+}$ ions in cobalt ferrite, while the intrinsic coercivity (H$_c$) was decreasing. Among these ferrites, copper ferrite exhibits highest sensitivity for humidity.

description: The JMMC Calibrator Workgroup has long developed methods to ascertain the angular diameter of stars, and provides this expertise in the SearchCal software. SearchCal dynamically finds calibrators near science objects by querying CDS hosted catalogs according to observational parameters. Initially limited to bright objects (K magnitude - 5.5), it has been upgraded with a new method providing calibrators without any magnitude limit but those of queried catalogs. We introduce here a new static catalog of stellar diameters, containing more than 38000 entries, obtained from SearchCal results aggregation on the whole celestial sphere, complete for all stars with HIPPARCOS parallaxes. We detail the methods and tools used to produce and study this catalog, and compare the static catalog approach with the dynamical querying provided by SearchCal engine. We also introduce a new Virtual Observatory service, enabling the reporting of, and querying about, stars flagged as "bad calibrators" by astronomers, adding this ever-growing database to our SearchCal service.
