Supply chain planning for bioenergy and biofuel production from forest-based residues in interior British Columbia : a simulation study
Creators: name: Siller Benitez, Diana Gabriela
Publisher: name: University of British Columbia
Year: 2016

description: This thesis analyzes a forest-based biomass supply chain network considering uncertainties and variations. It is based on the Williams Lake Timber Supply Area (TSA) located in British Columbia, Canada. The network includes: five conversion facilities distributed in three locations, two types of forest-based biomass, sourced from 337 cutblocks, and two types of sawmill residues sourced from three local sawmills. The main objective of this research is to evaluate the supply chain of forest-based residues for bioenergy and biofuel production considering uncertainties and variations. The specific objectives of this research are to: 1) Develop a simulation model to evaluate a forest-based biomass supply chain for bioenergy and biofuel production considering uncertainties and variations; and 2) apply the simulation model to a case study. To achieve the objectives, a discrete-event simulation model is developed using the commercial software Anylogic 7® (Anylogic 7, 2000). Evaluating a network with various supply and demand points, with various biomass types, and a hybrid push-pull biomass flow management distinguishes this work from previous research. The results show the demand is fulfilled to at least 95%, requiring 23 to 24 trucks during the peak season. Furthermore, the cost and CO₂ equivalent emissions vary per location, from $56.52 to $87.36 and from 19.66 to 72.61 (kg/odt), respectively. Long transportation distances and transportation cycle times greatly affected the number of required resources, and consequently the final cost per oven dry tonne. This results in higher costs than similar studies performed in less remote areas. Finally, a sensitivity analysis is performed to evaluate the effect of changes in moisture content and in supply and demand. Extreme changes in biomass supply and demand affected dramatically the demand fulfillment. By increasing the biomass demand 20% while simultaneously decreasing the biomass supply 20%, reduced the demand fulfillment by 23.18%. Finally, this model can be improved in several ways, one of them being by including the possibility of routing between different cutblocks to consolidate biomass pick-ups, therefore increasing the demand fulfillment of the supply chain and possibly reducing costs.

description: We present a combined theoretical and experimental study of the electronic structure and equation of state (EOS) of crystalline PdN2. The compound forms above 58 GPa in the pyrite structure and is metastable down to 11 GPa. We show that the EOS cannot be accurately described within either the local density or generalized gradient approximations. The Heyd-Scuseria-Ernzerhof exchange-correlation functional (HSE06), however, provides very good agreement with experimental data. We explain the strong pressure dependence of the Raman intensities in terms of a similar dependence of the calculated band gap, which closes just below 11 GPa. At this pressure, the HSE06 functional predicts a first-order isostructural transition accompanied by a pronounced elastic instability of the longitudinal-acoustic branches that provides the mechanism for the experimentally observed decomposition. Using an extensive Wannier function analysis, we show that the structural transformation is driven by a phase transition of the electronic structure, which is manifested by a discontinuous change in the hybridization between Pd-d and N-p electrons as well as a conversion from single to triple bonded nitrogen dimers. We argue for the possible existence of a critical point for the isostructural transition, at which massive fluctuations in both the electronic as well as the structural degrees of freedom are expected.

description: The multifrequency radio continuum and 21cm HI observations of five blue compact dwarf (BCD) galaxies, Mrk 104, Mrk 108, Mrk 1039, Mrk 1069 and I Zw 97 using the Giant Meterwave Radio Telescope (GMRT) are presented here. Radio continuum emission at 610 MHz and 325 MHz is detected from all the observed galaxies whereas only a few are detected at 240 MHz. In our sample, three galaxies are members of groups and two galaxies (Mrk 1069 and I Zw 97) are isolated galaxies. The radio emission from Mrk 104 and Mrk 108 is seen to encompass the entire optical galaxy whereas the radio emission from Mrk 1039, Mrk 1069, I Zw 97 is confined to massive HII regions. This, we suggest, indicates that the star formation in the latter group of galaxies has recently been triggered and that the environment in which the galaxy is evolving plays a role. Star formation rates (SFR) calculated from 610 MHz emission is in the range 0.01-0.1 M_sun/yr; this is similar to the SFR obtained for individual star forming regions in BCDs. The integrated radio spectra of four galaxies are modelled over the frequency range where data is available. We find that two of the galaxies Mrk 1069 and Mrk 1039, show a turnover at low frequencies which is well fitted by free-free absorption whereas the other two galaxies, Mrk 104 and Mrk 108, show a power law at the lowest GMRT frequencies. The flatter spectrum, localized star formation and radio continuum in isolated galaxies lend support to stochastic self-propagating star formation (SSPSF). The HI observations of four galaxies Mrk 104, Mrk 108, Mrk 1039 and Mrk 1069 show extended disks as large as ~1.1-6 times the optical size. All the observed BCDs (except Mrk 104) show rotating disk with a half power width of ~50-124 km/s. Solid body rotation is common in our sample. We note that the tidal dwarf (TD) origin is possible for two of the BCDs in our sample.

description: Intelligent products carrying their own information are more and more present nowadays. In recent years, some authors argued the usage of such products for the Supply Chain Management Industry. Indeed, a multitude of informational vectors take place in such environments like fixed databases or manufactured products on which we are able to embed significant proportion of data. By considering distributed database systems, we can allocate specific data fragments to the product useful to manage its own evolution. The paper aims to analyze the Supply Chain performance according to different strategies of information distribution. Thus, different distribution patterns between informational vectors are studied. The purpose is to determine the key factors which lead to improve information distribution performance in term of time properties.

description: An algorithm is given in this paper for the computation of dynamically equivalent weakly reversible realizations with the maximal number of reactions, for chemical reaction networks (CRNs) with mass action kinetics. The original problem statement can be traced back at least 30 years ago. The algorithm uses standard linear and mixed integer linear programming, and it is based on elementary graph theory and important former results on the dense realizations of CRNs. The proposed method is also capable of determining if no dynamically equivalent weakly reversible structure exists for a given reaction network with a previously fixed complex set.

description: We present 3.6 to 70 μm Spitzer photometry of 154 weak-line T Tauri stars (WTTS) in the Chamaeleon, Lupus, Ophiuchus and Taurus star formation regions, all of which are within 200 pc of the Sun. For a comparative study, we also include 33 classical T Tauri stars (CTTS) which are located in the same star forming regions. Spitzer sensitivities allow us to robustly detect the photosphere in the IRAC bands (3.6 to 8 μm) and the 24 μm MIPS band. In the 70 μm MIPS band, we are able to detect dust emission brighter than roughly 40 times the photosphere. These observations represent the most sensitive WTTS survey in the mid to far infrared to date, and reveal the frequency of outer disks (r = 3-50 AU) around WTTS. The 70 μm photometry for half the c2d WTTS sample (the on-cloud objects), which were not included in the earlier papers in this series, Padgett et al. (2006) and Cieza et al. (2007), are presented here for the first time. We find a disk frequency of 19% for on-cloud WTTS, but just 5% for off- cloud WTTS, similar to the value reported in the earlier works. WTTS exhibit spectral energy distributions (SEDs) that are quite diverse, spanning the range from optically thick to optically thin disks. Most disks become more tenuous than Ldisk/L* = 2 x 10^-3 in 2 Myr, and more tenuous than Ldisk/L* = 5 x 10^-4 in 4 Myr.

Simulation modeling of forest biomass operations and harvest residue moisture content
Creators: name: Pledger, Sean
Publisher: name: University of British Columbia
Year: 2016

description: In order to limit the effects of anthropogenic climate change the world is moving away from the use of fossil fuels as a primary energy source. Bioenergy is expected to form a substantial contribution to this transitional strategy. In order to increase bioenergy production, underutilized forest harvest residues are being targeted as a fuel source. Even with favorable policies in place to encourage their use, the processing and collection of these previously disregarded resources is often prohibitively expensive. Quality factors such as material moisture content also impact the viability of harvest residues for fuel purposes. As a result, careful operational planning is of great importance to sourcing high quality, economically feasible biomass. To gain a better understanding of the forest biomass supply chain, a simulation model was developed for a case study located in coastal British Columbia, Canada. A seasonal moisture content trend was identified and incorporated to help develop a strategy for sourcing high quality materials. It was found for BC’s coastal temperate rainforest environment that by delaying biomass collection until the second summer after timber harvest an average delivered moisture content of 28% can be achieved rather than 38% is operations proceed in the first summer. This reduction in delivered moisture content also led to a decrease in delivered cost from $72.08 to $67.95 per oven dried tonne. Trucking and equipment configurations were also examined to identify least cost approaches to biomass collection under varying conditions. Comparing high productivity and low productivity equipment configurations showed a $26.08/ODT cost increase when switching to less productive equipment. By employing an electric centralized grinder transporting unprocessed harvest residues, costs were shown to decrease for all cutblock groups with a cycle time of less than four and a half hours. Least cost fleet size was found to be largely dependent on the average cycle time to the biomass source. And the volume of available biomass at a given cutblock was found to have an impact on delivered costs with a 20% increase in biomass volume resulting in a cost decrease of greater than $2/ODT.

description: Refraction, interference, and diffraction serve as distinguishing features for wave-like phenomena. While they are normally associated only with a purely spatial wave-propagation pattern, analogs to interference and diffraction involving the spatio-temporal dynamics of waves in one dimension (1D) have been pointed out. Here we complete the triplet of analogies by discussing how spatio-temporal analogs to refraction are exhibited by a quantum particle in 1D that is scattering off a step barrier. Similarly, birefringence in spacetime occurs for a spin-1/2 particle in a magnetic field. These examples serve to illustrate basics of quantum time evolution from a new perspective.

description: We propose a new approach to generate and detect spin currents in graphene, based on a large spin-Hall response arising near the neutrality point in the presence of external magnetic field. Spin currents result from the imbalance of the Hall resistivity for the spin-up and spin-down carriers induced by Zeeman interaction, and do not involve spin-orbit interaction. Large values of the spin-Hall response achievable in moderate magnetic fields produced by on-chip sources, and up to room temperature, make the effect viable for spintronics applications.

description: We present a new detailed abundance study of field red horizontal branch (RHB) and blue horizontal branch (BHB) non-variable stars. High resolution and high S/N echelle spectra of 11 RHB and 12 BHB were obtained with the McDonald 2.7 m telescope, and the RHB sample was augmented by reanalysis of spectra of 25 stars from a recent survey. We derived stellar atmospheric parameters based on spectroscopic constraints, and computed relative abundance ratios for 24 species of 19 elements. The species include Si II and Ca II, which have not been previously studied in RHB and BHB (Teff < 9000 K) stars. The abundance ratios are generally consistent with those of similar-metallicity field stars in different evolutionary stages. We estimated the masses of the RHB and BHB stars by comparing their Teff--log g positions with HB model evolutionary tracks. The mass distribution suggests that our program stars possess masses of ~0.5 Msun. Finally, we compared the temperature distributions of field RHB and BHB stars with field RR Lyraes in the metallicity range -0.8 >~ [Fe/H] >~ -2.5. This yielded effective temperatures estimates of 5900K and 7400 K for the red and blue edges of the RR Lyrae instability strip.

DNA methylation in human development : methodologies and analytics for genome-wide studies
Creators: name: Price, Eva Magdalena Wagner
Publisher: name: University of British Columbia
Year: 2016

description: High-throughput methods have resulted in a large volume of studies measuring genome-wide DNA methylation (DNAm) in association with human health and disease. Understanding of DNAm patterns may be translated, for example, into predicting children at risk for illness or identifying etiological subtypes within a heterogeneous disease. Addressing biological and technical factors affecting measurement of genome-wide DNAm is essential to reduce false discovery in such studies. This dissertation develops principles for analyzing genome-wide DNAm, with the aim of improving collection and analysis of human developmental data. To this end, I present four studies employing several techniques to measure genome-wide DNAm: DNAm of L1 and Alu repetitive elements in addition to Illumina 27k and 450k DNAm microarrays. In the first of these studies, I found that tissue type, gestational age, technical platform and CpG density contribute to variable measurement of genome-wide DNAm. Subsequent studies primarily used the 450k array to measure genome-wide DNAm, a technology targeting 485,577 sites in the genome. A detailed annotation of the 450k array was created and tested, to enhance this platform’s utility. Array probes targeting sites containing SNPs (4.3%) and non-specific probes (8.6%) were identified, and I examined how these compromised probes may result in spurious discoveries. A pilot study in placental tissue identified batch effects in 450k data. A computational tool was applied to reduce the batch signal, but I demonstrated that when applied to a problematic study design, false biological signal may be introduced. The workflow for processing and analyzing genome-wide DNAm data was finally applied to profile five tissues ascertained from second trimester neural tube defect (NTD)-affect pregnancies. Despite research, medical interventions and public health changes, NTDs remain the second most common congenital abnormality in many parts of the world, and the etiology of these cases is unknown. Using the 450k array, I found 3,342 differentially methylated sites in the kidneys of spina bifida cases compared to gestational-age matched controls, but little alteration in genome-wide DNAm in other NTD tissues. This dissertation contributes methodologies and analytical tools that will help manage bias, improve reproducibility and reduce false discoveries in studies of genome-wide DNAm.
Evolution of the number of accreting white dwarfs with shell nuclear burning and of occurrence rate of SN Ia

Year: 2010
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We analyze temporal evolution of the number of accreting white dwarfs with shell hydrogen burning in semidetached and detached binaries. We consider a stellar system in which star formation lasts for 10 Gyr with a constant rate, as well as a system in which the same amount of stars is formed in a single burst lasting for 1 Gyr. Evolution of the number of white dwarfs is confronted to the evolution of occurrence rate of events that usually are identified with SN Ia or accretion-induced collapses, i.e. with accumulation of Chandrasekhar mass by a white dwarf or a merger of a pair of CO white dwarfs with total mass not lower than the Chandrasekhar one. In the systems with a burst of star formation, at $t=$10 Gyr observed supersoft X-ray sources, most probably, are not precursors of SN Ia. The same is true for an overwhelming majority of the sources in the systems with constant star formation rate. In the systems of both kinds mergers of white dwarfs is the dominant SN Ia scenario. In symbiotic binaries, accreting CO-dwarfs do not accumulate enough mass for SN Ia explosion, while ONeMg-dwarfs finish their evolution by an accretion-induced collapse with formation of a neutron star.

Year: 2023

description: The purpose of this project was to design a boxing trainer that can be attached to an existing punching bag and stand. The trainer will measure reaction time by selecting various targets and recording the time until the target is struck. A gyroscope and accelerometer are used to calculate the force behind each punch. This information is then displayed on an app that can be installed on android or IOS devices. This design was created to allow inexperienced boxers a method of training safely and without a trainer present. This also provides convenient access to practice in a time where trainers may be challenging to find or schedule time with.

Secondly, we discuss the results of a recent comparison we have performed on simulations of driven, supersonic turbulence with SPH and Eulerian techniques. Finally we present some new results on the relationship between the density variance and the Mach number in supersonic turbulent flows, finding sigma^2_{ln rho} = ln (1 + b^2 M^2) with b=0.33 up to Mach~20, consistent with other numerical results at lower Mach number (Lemaster and Stone 2008) but inconsistent with observational constraints on sigma_rho and M in Taurus and IC5146.

description: A growing body of literature exists on determinants of psychosocial reactions to human-robot collaboration (HRC), including variables such as prior experience working with robots, speed of human-robot interactions, and the level of proximity between the human and the robot. However, the results from this emerging literature and implications for occupational settings have largely been based on research involving traditional rigid robots. Advancements in novel soft growing flexible robots necessitates evaluating how and whether such prior research generalizes to this new class of robots. By manipulating speed and proximity of an HRC task and measuring psychosocial robot-related attitudes pre- and post-task among N = 112 research participants, we evaluated the main and interactive effects of speed, proximity, and prior robot exposure on perceived safety hazards, fear of robots, robot anxiety, technology-induced job insecurity, and social hesitancy towards robots. Following observations of HRC with the novel soft robot, participants perceived fewer safety hazards associated with working with robots, expressed less anxiety and fear about robots, reported less social hesitancy about HRC, and had lower levels of technology-induced fears of job insecurity. Proximity was unrelated to any of these outcomes, whereas fear of robots, perceived hazards, technology-induced job insecurity, and robot anxiety were all significantly lower under slower speed conditions. Finally, participants with more extensive prior robot experience displayed preferences for faster HRC interactions, compared to participants with less robot experience who had more positive reactions to slower HRC interactions. We discuss these implications in light of occupational applications and future research needs in the area of HRC with novel soft robots.

3D MHD simulations of subsurface convection in OB stars

description: During their main sequence evolution, massive stars can develop convective regions very close to their surface. These regions are caused by an opacity peak associated with iron ionization. Cantiello et al. (2009) found a possible connection between the presence of sub-photospheric convective motions and small scale stochastic velocities in the photosphere of early-type stars. This supports a physical mechanism where microturbulence is caused by waves that are triggered by subsurface convection zones. They further suggest that clumping in the inner parts of the winds of OB stars could be related to subsurface convection, and that the convective layers may also be responsible for stochastic excitation of non-radial pulsations. Furthermore, magnetic fields produced in the iron convection zone could appear at the surface of such massive stars. Therefore subsurface convection could be responsible for the occurrence of observable phenomena such as line profile variability and discrete absorption components. These phenomena have been observed for decades, but still evade a clear theoretical explanation. Here we present preliminary results from 3D MHD simulations of such subsurface convection.

Quasi-Spherical, Time-Dependent Viscous Accretion Flow: One-Dimensional Results

description: We investigated the instability of advective accretion flow as a consequence of angular momentum transfer in one-dimensional, quasi-spherical transonic accretion flow around a non-rotating black hole. The code is designed to include the effects of viscosity; the hydrodynamics component preserves angular momentum strictly with Lagrangian and remap method in absence of viscosity, while the viscosity component updates viscous angular momentum transfer through the implicit method. We performed two tests to demonstrate the suitability of the code for accretion study. First, we simulated the inviscid, low angular momentum, transonic accretion flow with shocks around a black hole, and then the subsonic, self-similar ADAF solution around a Newtonian object. Both simulations fitted the corresponding analytical curves extremely well. We then simulated a rotating, viscous, transonic fluid with shocks. We showed that for low viscosity parameter, stable shocks at larger distance are possible. For higher viscosity parameter, more efficient angular momentum transfer in the post-shock disk makes the shock structure oscillatory. Moreover, as the shock drifts to larger distances, a secondary inner shock develops. We showed that the inner shock is the direct consequence of expansion of the outer shock, as well as creation of regions with $\partial l / \partial r < 0$ due to more efficient angular momentum transfer near the inner sonic point. We showed that all disk parameters, including emissivity, oscillate with the same period as that of the shock oscillation. Our simulation may have implication for low frequency QPOs, e.g., GRO J1655-40 and XTE J1550-564.

Scandent tree : a decision forest based classification method for multimodal incomplete datasets
Creators: name: Hor, Soheil
Publisher: name: University of British Columbia
Year: 2016

description: Incomplete and inconsistent datasets often pose difficulties in multimodal studies. A common scenario in such studies is where many of the samples are non-randomly missing a large portion of the most discriminative features. We introduce the novel concept of scandent decision trees to tackle this issue in the context of a decision forest classifier. Scandent trees are decision trees that optimally mimic the partitioning of the data determined by another decision tree, and crucially, use only a subset of the feature set. We use the forest resulting from ensembling these trees as a classification model. We test the proposed method on a real world example of the target scenario, a prostate cancer dataset with MRI and gene expression modalities. The dataset is imbalanced with many MRI only samples and few with MRI and gene expression. Using scandent trees, we train a classifier that benefits from the large number of MRI samples at training time, and of the presence of MRI and gene expression features at the time of testing. The results show that the diagnostic value of the proposed model in terms of detecting prostate cancer is improved compared to traditional methods of imputation and missing data removal. The second major contribution of this work is the concept of tree-based feature maps in the decision forest paradigm. The tree-based feature maps enable us to train a classifier on a rich multimodal dataset, and use it to classify samples with only a subset of features of the training data. This has important clinical implications: one can benefit from an advanced modality to train a classifier, but use it in a practical situation when less expensive modalities are available. We use the proposed methodology to build a model trained on MRI and PET images of the Alzheimer's Disease Neuroimaging Initiative (ADNI) dataset, and then test it on cases with only MRI data. We show that our method is significantly more effective in staging of cognitive impairments compared to a model trained and tested on MRI only, or one that uses other kinds of feature transform applied to the MRI data.

description: While silicon has dominated solid-state electronics for more than four decades, a variety of new materials have been introduced into photonics to expand the accessible wavelength range and to improve the performance of photonic devices. For example, gallium-nitride based materials enable the light emission at blue and ultraviolet wavelengths, and high index contrast silicon-on-insulator facilitates the realization of ultra dense and CMOS compatible photonic devices. Here, we report the first deployment of graphene, a two-dimensional carbon material, as the photo-detection element in a 10 Gbits/s optical data link. In this interdigitated metal-graphene-metal photodetector, an asymmetric metallization scheme is adopted to break the mirror symmetry of the built-in electric-field profile in conventional graphene field-effect-transistor channels, allowing for efficient photo-detection within the entire area of light illumination. A maximum external photo-responsivity of 6.1 mA/W is achieved at 1.55 μm wavelength, a very impressive value given that the material is below one nanometer in thickness. Moreover, owing to the unique band structure and exceptional electronic properties of graphene, high speed photodetectors with an ultra-wide operational wavelength range at least from 300 nm to 6 μm can be realized using this fascinating material.
