Carbon capturing storage and utilization at building level : a feasibility study based on life cycle thinking
Creators: name: Liyanage, Don Rukmal Dhanushka
Publisher: name: University of British Columbia
Year: 2020

description: Anthropogenic greenhouse gas (GHG) emissions from fossil fuel combustion in energy generation are one of the main causes of climate change. It is important to mitigate climate change as it leads to extreme weather and climate events. Buildings are responsible for 40% of the energy consumption in the world. The majority of energy consumed in buildings is for heating in colder regions. Natural gas is a commonly used fuel for building heating despite the GHGs directly emitted during the operation of natural gas building heating systems. Although energy demand can be reduced with energy retrofits, it is impossible to completely eliminate the requirement of thermal energy from the current technologies. Adopting carbon capturing, storage, and utilization technologies at building level can be a solution for reducing the GHG emissions from natural gas building heating systems. However, feasibility assessment, research, and development of this technology are lacking in the current knowledge base. The main goal of this research is to investigate the feasibility of implementing carbon capturing, storage, and utilisation technologies in existing natural gas-based building heating systems. The study developed a life cycle thinking based comparative performance assessment framework to assess the life cycle environmental and economic performance of building-level carbon capturing technologies and compare them to alternative GHG emission mitigation methods used for building heating systems. A fuzzy logic based, multi-attribute decision making approach was used in the comparative performance assessment framework to consider both environmental and economic impacts simultaneously, while handling the uncertainties. The outcomes of the research will contribute to the development of building-level carbon capturing technologies and provide confidence to stakeholders to invest in them. In addition, the knowledge is useful for policy makers and governments in making decisions on climate change mitigation initiatives, while supporting the climate action targets of the Canadian government and global agreements.

description: A robust, user-friendly, and automated method to determine quantum conductance in disordered quasi-one-dimensional systems is presented. The scheme relies upon an initial density- functional theory calculation in a specific geometry after which the ground-state eigenfunctions are transformed to a maximally-localised Wannier function (MLWF) basis. In this basis, our novel algorithms manipulate and partition the Hamiltonian for the calculation of coherent electronic transport properties within the Landauer-Buttiker formalism. Furthermore, we describe how short- ranged Hamiltonians in the MLWF basis can be combined to build model Hamiltonians of large (>10,000 atom) disordered systems without loss of accuracy. These automated algorithms have been implemented in the Wannier90 code[Mostofi et al, Comput. Phys. Commun. 178, 685 (2008)], which is interfaced to a number of electronic structure codes such as Quantum-ESPRESSO, AbInit, Wien2k, SIESTA and FLEUR. We apply our methods to an Al atomic chain with a Na defect, an axially heterostructured Si/Ge nanowire and to a spin-polarised defect on a zigzag graphene nanoribbon.

description: The minimum error of unbiased parameter estimation is quantified by the quantum Fisher information in accordance to the Cramér-Rao bound. We indicate that only superposed NOON states by simultaneous measurements can achieve the maximum quantum Fisher information with form $$ for a given photon number distribution by a POVM in linear two-path interferometer phase measurement. We present a series of specified superposed states with infinite quantum Fisher information but with finite average photon numbers. The advantage of this unbounded quantum Fisher information will be beneficial to many applications in quantum technology.

description: Background: The allergy preventive effects of gut immune modulation by bacterial compounds are still not fully understood. Objective: We sought to evaluate the effect of bacterial lysate applied orally from the second until seventh months of life on the prevalence of allergic diseases at school age. Methods: In a randomized, placebo-controlled trial, 606 newborns with at least one allergic parent received orally a bacterial lysate consisting of heat-killed Gram-negative Escherichia coli Symbio and Gram-positive Enterococcus faecalis Symbio or placebo from week 5 until the end of month 7. A total of 402 children were followed until school age (6-11 years) for the assessment of current atopic dermatitis (AD), allergic rhinitis (AR), asthma and sensitization against aeroallergens. Results: AD was diagnosed in 11.0% (22/200) of children in the active and in 10.4% (21/202) of children in the placebo group. AR was diagnosed in 35% (70/200) of children in the active and in 38.1% (77/202) children in the placebo group. Asthma was diagnosed in 9% (18/199) of children in the active and in 6.6% (13/197) of children in the placebo group. Sensitization occurred in 46.5% (66/142) of participants in the active and 51.7% (76/147) in the placebo group. Conclusion: An oral bacterial lysate of heat-killed Gram-negative Escherichia coli and Gram-positive Enterococcus faecalis applied during the first 7 months of life did not influence the development of AD, asthma and AR at school age.

description: As part of a survey for radio pulsars with the Parkes 64-m telescope we have discovered PSR J1622-4950, a pulsar with a 4.3-s rotation period. Follow-up observations show that the pulsar has the highest inferred surface magnetic field of the known radio pulsars (B ~ 3e14 G), exhibits significant timing noise and appears to have an inverted spectrum. Unlike the vast majority of the known pulsar population, PSR J1622-4950 appears to switch off for many hundreds of days and even in its on-state exhibits extreme variability in its flux density. Furthermore, the integrated pulse profile changes shape with epoch. All of these properties are remarkably similar to the only two magnetars previously known to emit radio pulsations. The position of PSR J1622-4950 is coincident with an X-ray source that, unlike the other radio pulsating magnetars, was found to be in quiescence. We conclude that our newly discovered pulsar is a magnetar - the first to be discovered via its radio emission.

description: In sub-humid regions, declining maize (Zea mays L.) yield is majorly attributed to unreliable rainfall and high evapotranspiration demand during critical growth stages. However, there are limited farm technologies for conserving soil water and increasing water use efficiency (WUE) in rainfed production systems amidst a changing climate. This study aimed at assessing the performance of different climate smart agriculture (CSA) practices, such as mulching and permanent planting basins (PPB), on maize growth, yield, water use efficiency and soil moisture storage. Field experiments involving mulches of 2 cm (M_2 cm), 4 cm (M_4 cm) and 6 cm (M_6 cm) thickness, permanent planting basins of 20 cm (PPB_20 cm) and 30 cm (PPB_30 cm) depths and the control/or conventional treatments were conducted for three maize growing seasons in the sub-humid climate of Western Uganda. Results indicate that maize biomass significantly increased under the tested CSA practices in the study area. Use of permanent planting basins relatively increased maize grain yield (11–66%) and water use efficiency (33–94%) compared to the conventional practice. Additionally, plots treated with mulch achieved an increase in grain yield (18–65%) and WUE (28–85%) relative to the control. Soil amendment with M_4 cm and M_6 cm significantly increased soil moisture storage compared to permanent planting basins and the conventional practice. Overall, the results highlight the positive impact of CSA practices on improving maize yield and water use efficiency in rainfed agriculture production systems which dominate the sub-humid regions.
Identification, cloning, and functional characterization of Lavandula floral development genes
Creators: name: Wells, Rebecca
Publisher: name: University of British Columbia

description: The molecular aspects of flower initiation and development have not been adequately investigated in lavender (Lavandula). In order to identify genes that control these processes, I employed RNA-Seq to obtain sequence information for transcripts originating from the vegetative shoot apical meristem (SAM) and developing inflorescence tissues of Lavandula angustifolia and Lavandula × intermedia plants, and assembled a comprehensive transcriptome of 105,294 contigs. Homology-based annotation provided gene ontology terms for the majority of transcripts, including over 100 genes homologous to those that control flower initiation and organ identity in Arabidopsis thaliana. Expression analysis revealed that most of these genes are differentially expressed during flower development. For example, LaSVP, a homolog of the floral repressor SHORT VEGETATIVE PHASE (SVP), was strongly expressed in vegetative SAM compared to developing flowers, implicating its potential involvement in flowering repression in lavender. In total, fourteen full-length lavender transcription factor homologs were identified. To investigate these genes further, I constitutively expressed each gene in transformed A. thaliana plants, evaluating the effects on flower initiation and morphology. Expression of the Lavandula genes in A. thaliana was gene- dependent. Phenotypic effects were observed for LaCC, LaFT, and LaSVP transformants. For example, constitutive expression of the LaSVP gene in A. thaliana delayed flowering and affected flower organ identity in a dosage- dependent manner. Four of the highest expressing lines produced sepals instead of petals and were sterile as they failed to develop proper seed pods. This study provides the foundation for future investigations aimed at elucidating flower initiation and development in lavender.

description: We propose using coupled deep learning based super-resolution restoration (SRR) and single-image digital terrain model (DTM) estimation (SDE) methods to produce subpixel-scale topography from single-view ESA Trace Gas Orbiter Colour and Stereo Surface Imaging System (CaSSIS) and NASA Mars Reconnaissance Orbiter High Resolution Imaging Science Experiment (HiRISE) images. We present qualitative and quantitative assessments of the resultant 2 m/pixel CaSSIS SRR DTM mosaic over the ESA and Roscosmos Rosalind Franklin ExoMars rover’s (RFEXM22) planned landing site at Oxia Planum. Quantitative evaluation shows SRR improves the effective resolution of the resultant CaSSIS DTM by a factor of 4 or more, while achieving a fairly good height accuracy measured by root mean squared error (1.876 m) and structural similarity (0.607), compared to the ultra-high-resolution HiRISE SRR DTMs at 12.5 cm/pixel. We make available, along with this paper, the resultant CaSSIS SRR image and SRR DTM mosaics, as well as HiRISE full-strip SRR images and SRR DTMs, to support landing site characterisation and future rover engineering for the RFEXM22.

description: Fluorinated graphitic layers with good mechanical and chemical stability, polar C–F bonds, and tunable bandgap are attractive for a variety of applications. In this work, we investigated the photolysis of fluorinated graphites with interlayer embedded acetonitrile, which is the simplest representative of the acetonitrile-containing photosensitizing family. The samples were continuously illuminated in situ with high-brightness non-monochromatized synchrotron radiation. Changes in the compositions of the samples were monitored using X-ray photoelectron spectroscopy and near-edge X-ray absorption fine structure (NEXAFS) spectroscopy. The NEXAFS N K-edge spectra showed that acetonitrile dissociates to form HCN and N2 molecules after exposure to the white beam for 2 s, and the latter molecules completely disappear after exposure for 200 s. The original composition of fluorinated matrices CF0.3 and CF0.5 is changed to CF0.10 and GF0.17, respectively. The highly fluorinated layers lose fluorine atoms together with carbon neighbors, creating atomic vacancies. The edges of vacancies are terminated with the nitrogen atoms and form pyridinic and pyrrolic units. Our in situ studies show that the photolysis products of acetonitrile depend on the photon irradiation duration and composition of the initial CFx matrix. The obtained results evaluate the radiation damage of the acetonitrile-intercalated fluorinated graphites and the opportunities to synthesize nitrogen-doped graphene materials.

description: Aims. We present a spectroscopic analysis of a sample of evolved stars in M67 (turn-off, subgiant and giant stars) in order to bring observational constraints to evolutionary models taking into account non-standard transport processes. Methods. We determined the stellar parameters (Teff, log g, [Fe/H]), microturbulent and rotational velocities and, Lithium abundances (ALi) for 27 evolved stars of M67 with the spectral synthesis method based on MARCS model atmospheres. We also computed non-standard stellar evolution models, taking into account atomic diffusion and rotation-induced transport of angular momentum and chemicals that were compared with this set of homogeneous data. Results. The lithium abundances that we derive for the 27 stars in our sample follow a clear evolutionary pattern ranging from the turn-off to the Red Giant Branch. Our abundance determination confirms the well known decrease of lithium content for evolved stars. For the first time, we provide a consistent interpretation of both the surface rotation velocity and of the lithium abundance patterns observed in an homogeneous sample of TO and evolved stars of M67. We show that the lithium evolution is determined by the evolution of the angular momentum through rotation-induced mixing in low-mass stars, in particular for those with initial masses larger than 1.30 M_\odot at solar metallicity.

description: The subject of the graduate qualification work is âMeasurement of Lu-177 activity by absolute methodsâ. This work is devoted to the calculation of the specific activity of a counting sample of lutetium-177 using several methods. In the first case, we consider the coincidence method, where we change the efficiency by using different films. In the second case, we will use one film, but change the efficiency programmatically when processing data. In the third case, we will use the TDCR method. Compare the resulting values and calculate the uncertainty budget for the coincidence method.

As an illustration of the general procedure we perform the matching of the Isgur-Karl model for the spectrum of the negative parity L=1 excited baryons. Assuming the most general two-body quark Hamiltonian, we derive two correlations among the masses and mixing angles of these states which should hold in any quark model. These correlations constrain the mixing angles and can be used to test for the presence of three-body quark forces.

description: We describe the CRASH (Center for Radiative Shock Hydrodynamics) code, a block adaptive mesh code for multi-material radiation hydrodynamics. The implementation solves the radiation diffusion model with the gray or multigroup method and uses a flux limited diffusion approximation to recover the free-streaming limit. The electrons and ions are allowed to have different temperatures and we include a flux limited electron heat conduction. The radiation hydrodynamic equations are solved in the Eulerian frame by means of a conservative finite volume discretization in either one, two, or three-dimensional slab geometry or in two-dimensional cylindrical symmetry. An operator split method is used to solve these equations in three substeps: (1) solve the hydrodynamic equations with shock-capturing schemes, (2) a linear advection of the radiation in frequency-logarithm space, and (3) an implicit solve of the stiff radiation diffusion, heat conduction, and energy exchange. We present a suite of verification test problems to demonstrate the accuracy and performance of the algorithms. The CRASH code is an extension of the Block-Adaptive Tree Solarwind Roe Upwind Scheme (BATS-R-US) code with this new radiation transfer and heat conduction library and equation-of-state and multigroup opacity solvers. Both CRASH and BATS-R-US are part of the publicly available Space Weather Modeling Framework (SWMF).

description: Not all eye-tracking methodology and data processing are equal. While the use of eye-tracking is intricate because of its grounding in visual physiology, traditional 2D eye-tracking methods are supported by software, tools, and reference studies. This is not so true for eye-tracking methods applied in virtual reality (imaginary 3D environments). Previous research regarded the domain of eye-tracking in 3D virtual reality as an untamed realm with unaddressed issues. The present paper explores these issues, discusses possible solutions at a theoretical level, and offers example implementations. The paper also proposes a workflow and software architecture that encompasses an entire experimental scenario, including virtual scene preparation and operationalization of visual stimuli, experimental data collection and considerations for ambiguous visual stimuli, post-hoc data correction, data aggregation, and visualization. The paper is accompanied by examples of eye-tracking data collection and evaluation based on ongoing research of indoor evacuation behavior.

description: A particular class of space-time, with a tachyon field, ϕ, and a barotropic fluid constituting the matter content, is considered herein as a model for gravitational collapse. For simplicity, the tachyon potential is assumed to be of inverse square form i.e., V(ϕ) \sim ϕ^{-2}. Our purpose, by making use of the specific kinematical features of the tachyon, which are rather different from a standard scalar field, is to establish the several types of asymptotic behavior that our matter content induces. Employing a dynamical system analysis, complemented by a thorough numerical study, we find classical solutions corresponding to a naked singularity or a black hole formation. In particular, there is a subset where the fluid and tachyon participate in an interesting tracking behaviour, depending sensitively on the initial conditions for the energy densities of the tachyon field and barotropic fluid. Two other classes of solutions are present, corresponding respectively, to either a tachyon or a barotropic fluid regime. Which of these emerges as dominant, will depend on the choice of the barotropic parameter, γ. Furthermore, these collapsing scenarios both have as final state the formation of a black hole.

Network codes for eﬀective resource allocation in cache-enabled 5G mobile networks
Creators: name: Saif, Mohammed
Publisher: name: University of British Columbia

description: Cooperation is a key enabler for delivering popular contents to users in today's centralized wireless communication networks where the cloud-computing base station (CBS) is connected with low power base-stations, also named as remote radio heads (RRHs), via fronthaul links. The performance of today's wireless communication networks is constrained by the scarcity of radio resources and limited-capacity of fronhaul links. Edge caching (EC) is a powerful networking technique, where popular contents are cached in the edge nodes, that reduces the burden on fronthaul links. State-of-the-art literature on content delivery focuses on allocating a single user to each radio resource-block (RRB). However, this needs a large numbers of RRBs to satisfy the tremendous increase in the number of users. Consequently, network coding (NC) is employed to mix users' contents and simultaneously allocate different users to the same RRB. This dissertation designs innovative NC schemes for effective resource allocation in cache-enabled 5G networks, where the goal is to optimize different metrics, such as throughput, CBS offloading, and completion time. We first study the cross-layer throughput maximization problem in cloud-radio access network (C-RAN). For this problem, we develop novel cross-layer NC (CLNC) frameworks that propose to optimize RRHs' transmit powers and users' rates in making the coding decisions. Subsequently, we study CBS offloading and users' quality of service (QoS)-guarantee trade-off for fog-RAN system subject to the cached contents, the required minimum rate, power control, and NC constraints. Next, we focus on developing NC schemes for device-to-device (D2D)-aided F-RAN system. The developed NC schemes exploit the aforementioned F-RAN's optimization factors and potential D2D communications to minimize the completion time of users. Finally, to circumvent the necessity for CBSs in the above-mentioned centralized systems, we develop a distributed and decentralized game-theoretical NC framework for partially connected D2D networks such that the number of required D2D transmissions until all users receive all their requested contents is minimized. Simulation results are provided to attest the effectiveness of the proposed frameworks against baseline schemes for each of the above systems.

description: Negli ultimi anni, lo sviluppo dell’intelligenza artificiale ha subito una forte impennata, in particolar modo nelle tecniche di machine learning. Di conseguenza, l’impiego di queste tecnologie è aumentato sia nella sicurezza informatica, sia nello sviluppo di nuovi attacchi ai sistemi informativi. Allo stato attuale, il machine learning rappresenta un alleato indispensabile per la protezione delle reti aziendali e per l’analisi dei rischi. Tuttavia, il vantaggio di queste soluzioni resta incerto vista l’evoluzione parallela delle minacce. L’obiettivo di questo progetto è quello di ricercare le tecnologie e i metodi utilizzati dai ricercatori e dai criminali informatici. A tal proposito, vengono illustrate le definizioni relative all’intelligenza artificiale; dopodiché, vengono presentate e analizzate le varie soluzioni esistenti. Infine, attraverso un’applicazione pratica, viene testata l’efficacia e i limiti di una di queste tecniche per la sicurezza informatica. --- In recent years, the development of artificial intelligence has experienced a sharp surge, especially in machine learning techniques. Consequently, the use of these technologies has increased both in cybersecurity and in the development of new attacks on information systems. At present, machine learning represents an indispensable ally for the protection of company networks and risk analysis. The advantage of these solutions remains however uncertain, given the parallel evolution of possible threats.

Pulsar Timing Sensitivity to Very-Low-Frequency Gravitational Waves

description: At nanohertz frequencies gravitational waves (GWs) cause variations in time-of-arrival of pulsar signals potentially measurable via precision timing observations. Here we compute very-low-frequency GW sensitivity constrained by instrumental, propagation, and other noises fundamentally limiting pulsar timing observations. Reaching expected GW signal strengths will require estimation and removal of $\simeq$99% of time-of-arrival fluctuations caused by typical interstellar plasma turbulence and a reduction of white rms timing noise to $\sim$100 nsec or less. If these were achieved, single-pulsar signal-to-noise ratio (SNR) = 1 sensitivity is then limited by the best current terrestrial time standards at $h_{rms} \sim$2 $\times 10^{-16}$ [f/(1 cycle/year)]$^{-1/2}$ for $f < 3 \times 10^{-8}$ Hz, where f is Fourier frequency and a bandwidth of 1 cycle/(10 years) is assumed. This sensitivity envelope may be optimistic in that it assumes negligible intrinsic pulsar rotational noise, perfect time transfer from time standard to observatory, and stable pulse profiles. Nonetheless it can be compared to predicted signal levels for a broadband astrophysical GW background from supermassive black hole binaries. Such a background is comparable to timekeeping-noise only for frequencies lower than about 1 cycle/(10 years), indicating that reliable detections will require substantial improvements in signal-to-noise ratio through pulsar array signal processing.

description: We provide a definition of integral, along paths in the Sierpinski gasket K, for differential smooth 1-forms associated to the standard Dirichlet form K. We show how this tool can be used to study the potential theory on K. In particular, we prove: i) a de Rham reconstruction of a 1-form from its periods around lacunas in K; ii) a Hodge decomposition of 1-forms with respect to the Hilbertian energy norm; iii) the existence of potentials of smooth 1-forms on a suitable covering space of K. We finally show that this framework provides versions of the de Rham duality theorem for the fractal K.

description: Questo lavoro di tesi mira ad esplorare la tematica degli stereotipi di genere nel contesto della Scuola dell’infanzia di Bedigliora, in cui ho svolto la mia pratica professionale III. Nello specifico, l’oggetto d’indagine verte sul comprendere se sia già effettivamente possibile riscontrare la presenza di stereotipi di genere in bambini di 5 e 6 anni (corrispondenti al secondo anno di frequenza obbligatoria), e in seguito nel riportare quali effetti sia possibile rilevare attraverso la proposta di un percorso pedagogico-didattico improntato alla parità dei ruoli di genere. Mediante diverse attività ludiche e di riflessione ho cercato di sensibilizzare a una prima presa di consapevolezza da parte di bambine e bambini sul loro essere persone uniche e speciali, i quali attraverso le loro potenzialità possono proprio “fare tutto”. I dati raccolti hanno evidenziato come le bambine del campione abbiano accolto con più facilità questo aspetto inclusivo di parità tra i generi, mettendo in luce come per loro anche le femmine possano svolgere lavori e mansioni maschili. Per contro, i risultati del campione maschile evidenziano come, in generale, essi siano maggiormente vincolati a rimanere agganciati a dei modelli sociali tradizionali più stereotipati, anche in merito al fatto che nella loro quotidianità possono contare su meno modelli alternativi in cui identificarsi rispetto alle compagne.

description: In this paper we present a new method, which allows for the construction of triangular isosurfaces from three-dimensional data sets, such as 3D image data and/or numerical simulation data that are based on regularly shaped, cubic lattices. This novel volume-enclosing surface extraction technique, which has been named VESTA, can produce up to six different results due to the nature of the discretized 3D space under consideration. VESTA is neither template-based nor it is necessarily required to operate on 2x2x2 voxel cell neighborhoods only. The surface tiles are determined with a very fast and robust construction technique while potential ambiguities are detected and resolved. Here, we provide an in-depth comparison between VESTA and various versions of the well-known and very popular Marching Cubes algorithm for the very first time. In an application section, we demonstrate the extraction of VESTA isosurfaces for various data sets ranging from computer tomographic scan data to simulation data of relativistic hydrodynamic fireball expansions.
