description: The seeds and oil yield and profile/levels of fatty acids, tocopherols and phytosterols in seed oils of twelve Japanese quince (Chaenomeles japonica) genotypes were studied. The seeds and oil yield ranged from 3.8 to 5.7% w/w fresh fruit, and 10.9 to 14.6% w/w dry weight seeds, respectively. The range of three predominated fatty acids C16:0, C18:1 and C18:2 in the seed oil of twelve Japanese quince genotypes were 8.1–9.8, 37.5–48.1, and 40.1–50.3%, respectively. α-Tocopherol and β-sitosterol were the main minor lipophilic compounds detected in all investigated genotypes. The percentage of predomination of α-tocopherol and β-sitosterol in each investigated genotype was very similar and amounted to 97–99% of total tocopherols and 76–80% of total phytosterols, respectively. The range of total content tocopherols and phytosterols in 12 genotypes of Japanese quince were 91.9–129.3 and 7830–14166 mg/100 g oil, respectively.

description: Thermal recovery techniques, like Steam-Assisted Gravity Drainage (SAGD), are used to produce the majority of the crude bitumen, in Canada. However, suboptimal production techniques have led to the use of automatic control techniques for production, in recent times. Concurrently, while Proportional Integral Derivative and single variable Model Predictive Control (MPC) strategies have proven to be superior to manual control, they have resulted in comparable performance. Consequently, for improved performance, a novel Multi Input Multi Output (MIMO) MPC is presented in this thesis and compared with a Multi Input Single Output (MISO) MPC. The results indicated a 171% improvement in oil recovery for the novel MIMO MPC over the MISO MPC. This thesis also presents an optimization strategy for integrated design and schedule of a partial bitumen upgrader. The key consideration is in identifying that the design and operation problems are not mutually exclusive, but instead, synergistic in nature. Consequently, the research documented in this thesis, elucidates two formulations; maximizing proﬁt and minimizing energy usage to highlight this concept. The results highlighted that both the design and scheduling decision variables change as per the medium term forecasts of the volatile commodity and energy pricing markets. Therefore, a design independent of the scheduling constraints or a schedule based on a ﬁxed design may lead to suboptimal results in the design and/or schedule decision space(s). Finally, the last part of the thesis focuses on the optimal power management of a microgrid on a depleted SAGD facility, comprising of an Organic Rankine Cycle based turbine to convert the geothermal SAGD waste heat into electricity, a Gas Turbine, a Battery Storage System, the central grid, and the facility itself. Furthermore, this work also introduces a Kelly Criterion (KC) based microgrid scheduling technique, which is based on maximizing information gain and is independent of supply-demand relationships. Moreover, for this study, a wavelet network based forecasting technique is used to capture the electricity market volatility. The case study presented corroborated the hypothesis that the KC approach is independent of demand and supply forecasts, and is able to perform optimally in a highly volatile energy market.
On the Optimal Solution of Large Eigenpair Problems
Creators: name: Kuczynski, Jacek

Subjects: Computer science

description: The problem of approximation of an eigenpair of a large n × n matrix A is considered. We study algorithms which approximate an eigenpair of A using the partial information on A given by b, Ab, …, Ajb, j << n, i.e., by Krylov subspaces. A new algorithm called the generalized minimal residual (gmr) algorithm is analyzed. Its optimality for some classes of matrices is proved. We compare the gmr algorithm with the widely used Lanczos algorithm for symmetric matrices. The gmr and Lanczos algorithms cost essentially the same per step and they have the same stability characteristics. Since the gmr algorithm never requires more steps than the Lanczos algorithm, and sometimes uses substantially fewer steps, the gmr algorithm seems preferable. We indicate how to modify the gmr algorithm in order to approximate p eigenpairs of A. We also show some other problems which can be nearly optimally solved by gmr-type algorithms. The gmr algorithm for symmetric matrices was implemented and some numerical results are described. The detailed implementation, more numerical results, and the Fortran subroutine can be found in KuczyÅ„ski (“Implementation of the gmr Algorithm for Large Symmetric Eigenproblems,“ Report, Columbia University, 1985). The Fortran subroutine is also available via anonymous FTP as “pub/gmrval“ on COLUMBIA-EDU [128.59.16.1] on the Arpanet.

description: The idea of using artificial intelligence techniques to support programming has been around for a long time. The earliest notion was to avoid programming entirely. The human user would just tell the computer what to do, without saying how to do it, and the computer would do the right thing. Even if this were feasible, however, it would be much too tedious, since each time the user would have to repeat the details of what he wanted done. So the goal of programming was to explain things to the computer only once, and then later on be able to tell the computer to do the same thing again in some short form, such as the name of the "program." Thus the idea evolved that a user would somehow tell the computer what program was desired, and the computer would write down the program in some internal form so that it could be remembered and repeated later. The assumption was that the resulting program would be correct, complete, efficient, easy to use, and so forth. It would also be exactly what the human user wanted.

description: Tadpole cancellation in Sen limits in F-theory was recently studied by Aluffi and Esole. We extend their results, generalizing the elliptic fibrations they used and obtaining a new case of universal tadpole cancellation, at least numerically. We could not find an actual Sen limit having the correct brane content, and we argue that such a limit may not exist. We also give a uniform description of the fibration used by Aluffi and Esole as well as a new, simple, fibration which has non-Kodaira type fibers.

Does the plateau in the NIRS-derived [HHb] signal in the vastus lateralis represent the upper limit in O2 extraction during ramp incremental cycling?

description: Oxygen (O2) extraction and O2 delivery represent the two critical components for muscle metabolism and have been extensively studied. The near-infrared spectroscopy (NIRS) derived O2 extraction signal ([HHb]) has been widely used for characterizing the peripheral response to exercise. Research examining this signal in response to ramp-incremental cycling has identified a linear increase followed by a plateau ([HHb]PLATEAU) prior to the achievement of maximal oxygen uptake (V̇O2max). Despite the common occurrence of this plateau, beyond speculation no research has been conducted to examine the underlying mechanisms causing the plateau in this signal. The studies in this thesis contribute to the understanding of the mechanisms that mediate the [HHb]PLATEAU by examining the maximal achievable level of O2 extraction at the end of a ramp-incremental test in different populations. In this two-part study 26 subjects were tested and divided into groups based on sex and training status. The results from the first part of this study demonstrated the existence of a reserve in O2 extraction and suggest that the [HHb]PLATEAU does not represent the upper limit of extraction in the vastus lateralis muscle. Additionally, the second part of this study revealed that sex and training status do not influence the amplitude of the reserve.
An efficient CMOS RF power extraction circuit for long-range passive RFID tags
Creators: name: Sharif Bakhtiar, Alireza
Publisher: name: University of British Columbia
Year: 2011

description: Effective matching and efficient power conversion play key roles in long- range power telemetry. This thesis discusses challenges and suggests solutions for long-range power telemetry with an emphasis on radio-frequency identification (RFID) applications. As a proof-of-concept a radio-frequency (RF) power harvesting system in a 0.13-µm CMOS technology is designed, fabricated, and successfully tested. The RF power harvesting system must maintain matching over the the wide operation frequency range of passive RFID tags, mandated by EPC- global. In this work, we first analyze the series-inductor matching network and show that there is a trade-o between bandwidth and efficiency. We then derive some guidelines for matching circuit design for RFID tags. To solve the matching problem over a wide frequency range, an adaptive matching system is proposed. At the startup, this system turns on while the rest of the chip is still inactive, and automatically tunes the matching network to achieve its maximum output voltage. Then the rest of the chip wakes up and functions as normal. A new CMOS rectifier stage is also proposed. This stage is capable of efficient operation even with very low input powers. In addition, this rectifier stage can be cascaded to reach higher output voltages without significantly compromising the overall efficiency. Combination of low-power performance and cascadability makes this rectifier suitable for long-range RFID tags. The test setup and measurement results are also discussed in a separate chapter. The measurement results show a 50% rectifiers efficiency at 4-µW input power. To the best of our knowledge, to date, this is the highest efficiency reported for rectifiers operating at such a low input power. Also, as compared to the output voltage at the nominal center frequency of the input matching network, the system shows less than 6% drop in output voltage over the entire 55-MHz bandwidth of the system which verifies the effectiveness of adaptive matching.

Small molecules as modulators of mitotic arrest and senescence in cancer
Creators: name: Riffell, Jenna Louise
Publisher: name: University of British Columbia
Year: 2011

description: Manipulation of the cell cycle is an extensively used and promising strategy for cancer therapy. To identify novel cell cycle modulators, automated fluorescence microscopy assays were designed and used to screen chemical libraries for modulators of mitotic arrest and senescence. 8-azaguanine, IC 261, erysolin and SKF 96365 were identified as chemicals that stimulate senescence, a state of prolonged growth arrest, in a p53-mutated growth arrest-deficient cell line. Microtubule-targeting cancer therapies such as paclitaxel block cell cycle progression at mitosis by prolonged activation of the mitotic checkpoint. Cells arrested in mitosis may remain arrested for extended periods of time, or undergo mitotic slippage through degradation of cyclin B1 in the presence of an active mitotic checkpoint and enter interphase without having separated their chromosomes. Regulation of extended mitotic arrest and mitotic slippage and their contribution to subsequent cell death or survival is incompletely understood. Chlorpromazine and triflupromazine were identified as drugs that inhibit mitotic exit through mitotic slippage. Using these drugs to extend mitotic arrest imposed by low concentrations of paclitaxel led to increased cell survival and proliferation after drug removal. SU6656 and geraldol were identified as chemicals that induce mitotic slippage. Cells arrested at mitosis with paclitaxel or vinblastine and induced by these compounds to undergo mitotic slippage underwent several rounds of DNA replication without cell division and exhibited signs of senescence but eventually all died. These results show that reinforcing mitotic arrest with drugs that inhibit mitotic slippage can lead to increased cell survival and proliferation, while inducing mitotic slippage in cells treated with microtubule-targeting drugs seems to invariably lead to protracted cell death. Mitotic slippage induced by SU6656 or geraldol involved proteasome-dependent degradation of cyclin B1, but also required proteasome- and caspase-3-dependent inactivation of the mitotic checkpoint through degradation of the mitotic checkpoint protein BubR1. Caspase-3 and p53, both apoptotic effectors, did not affect cell death after exposure to paclitaxel, with or without mitotic slippage induction. The requirement for caspase-3 for chemically induced mitotic slippage reveals a new mechanism for mitotic exit and a link between mitosis and apoptosis that has implications for the outcome of cancer chemotherapy.

description: Using the Reduced Basis approach, we efficiently compress and accurately represent the space of waveforms for non-precessing binary black hole inspirals, which constitutes a four dimensional parameter space (two masses, two spin magnitudes). Compared to the non-spinning case, we find that only a {\it marginal} increase in the (already relatively small) number of reduced basis elements is required to represent any non-precessing waveform to nearly numerical round-off precision. Most parameters selected by the algorithm are near the boundary of the parameter space, leaving the bulk of its volume sparse. Our results suggest that the full eight dimensional space (two masses, two spin magnitudes, four spin orientation angles on the unit sphere) may be highly compressible and represented with very high accuracy by a remarkably small number of waveforms, thus providing some hope that the number of numerical relativity simulations of binary black hole coalescences needed to represent the entire space of configurations is not intractable. Finally, we find that the {\it distribution} of selected parameters is robust to different choices of seed values starting the algorithm, a property which should be useful for indicating parameters for numerical relativity simulations of binary black holes. In particular, we find that the mass ratios $m_1/m_2$ of non-spinning binaries selected by the algorithm are mostly in the interval $[1,3]$ and that the median of the distribution follows a power-law behavior $\sim (m_1/m_2)^{-5.25}$.

description: We provide evidence that the obliquities of stars with close-in giant planets were initially nearly random, and that the low obliquities that are often observed are a consequence of star-planet tidal interactions. The evidence is based on 14 new measurements of the Rossiter-McLaughlin effect (for the systems HAT-P-6, HAT-P-7, HAT-P-16, HAT-P-24, HAT-P-32, HAT-P-34, WASP-12, WASP-16, WASP-18, WASP-19, WASP-26, WASP-31, Gl 436, and Kepler-8), as well as a critical review of previous observations. The low-obliquity (well-aligned) systems are those for which the expected tidal timescale is short, and likewise the high-obliquity (misaligned and retrograde) systems are those for which the expected timescale is long. At face value, this finding indicates that the origin of hot Jupiters involves dynamical interactions like planet-planet interactions or the Kozai effect that tilt their orbits, rather than inspiraling due to interaction with a protoplanetary disk. We discuss the status of this hypothesis and the observations that are needed for a more definitive conclusion.

Canonical approximation in the performance analysis of distributed systems
Creators: name: Pinsky, Eugene
Publisher: name: Columbia University
Year: 1986
Subjects: Computer science

description: The problem of analyzing distributed systems arises in many areas of computer science, such as communication networks, distributed databases, packet radio networks, VLSI communications and switching mechanisms. Analysis of distributed systems is difficult since one must deal with many tightly-interacting components. The number of possible state configurations typically grows exponentially with the system size, making the exact analysis intractable even for relatively small systems. For the stochastic models of these systems, whose steady-state probability is of the product form, many global performance measures of interest can be computed once one knows the normalization constant of the steady-state probability distribution. This constant, called the system partition function, is typically difficult to derive in closed form. The key difficulty in performance analysis of such models can be viewed as trying to derive a good approximation to the partition function or calculate it numerically. In this Ph.D. work we introduce a new approximation technique to analyze a variety of such models of distributed systems. This technique, which we call the method of Canonical Approximation, is similar to that developed in statistical physics to compute the partition function. The new method gives a closed-form approximation of the partition function and of the global performance measures. It is computationally simple with complexity independent of the system size, gives an excellent degree of precision for large systems, and is applicable to a wide variety of problems. The method is applied to the analysis of multihop packet radio networks, locking schemes in database systems, closed queueing networks, and interconnection networks.

description: This project explores the teaching of evolution in non-formal education centres in Alberta. It aims to define goals for evolution education in non-formal science learning spaces (museums, zoos, science centres, and aquariums), examine the unique nature of free-choice learning, and initiate a dialogue on best practice between exhibit designers, collections managers, and educators. The project examines the literature on evolution education and non-formal science education, fosters dialogue with participants that are employed in exhibit design and education, and observes exhibits in facilities across North America. I advocate for inclusion of interpretive pedagogy and interactive exhibit styles that are rooted in inquiry and creativity and use the resources at hand to illustrate evolution principles in a manner that addresses barriers to evolution understanding, is accessible and relevant to diverse visitor audiences, and is targeted at mission-based goals related to the specific facility.

description: The effects of a Planck-scale deformation of the Minkowski energy-momentum dispersion relation on the phenomenology of non-trapped Bose-Einstein condensates (BECs) are examined. Such a deformation is shown to cause a shift in the condensation temperature $T_{c}$ of the BEC and, for a specific functional form of deformation, this shift can be as large as the current measured precision on $T_{c}$. For a $_{37}^{85}Rb$ cold-atom BEC with a particle density $n\simeq 10^{12}cm^{-3}$ we find a fractional shift of order $10^{-4}$, but this can be much larger for even more dilute BECs. We discuss the possibility of planning specific experiments with BECs that might provide phenomenological constraints on Planck-scale physics. These corrections to $T_{c}$ are found to be extremely small for ultrarelativistic BECs implying that, in some cases, Planck-scale effects may be more important in low- rather than high-energy processes.

description: Laser powder bed fusion (LPBF) is a rapidly emerging manufacturing technology capable of producing complex part geometries through the repeated, precise laser melting of metallic powder layers. At present, the process is primarily employed in high-value-added applications which exist in the aerospace, biomedical, and dental industries. As industrial implementation of LPBF has matured, research has focused on established materials for which there are already large bodies of literature and regulatory approval, such as Inconel 718, Inconel 625, Ti-6Al-4V, and 316 stainless steel. However, the rapid solidification process inherent to LPBF leads to vastly different microstructures with improved strength compared to these traditional materials in cast or wrought forms. In general, the high solidification velocity and thermal gradients result in cellular and dendritic solidification structures with finer grain and precipitate sizes than conventionally processed alloys. These microstructure changes warrant the exploration of new alloy systems and reevaluation of historically cast compositions with optimized microstructures, especially considering the tunability of a digitally controlled fabrication process. This work examines laser powder bed fusion of Mar-M 509, a carbide-strengthened cobalt alloy that is typically investment cast directly into complex-shaped components such as nozzle guide vanes (NGVs). NGVs are stationary components in gas turbine engines for propulsion and energy production which require strength under moderate mechanical loading at high temperatures. Investment cast microstructures have porosity defects in slower-cooled regions due to lack of liquid feed to interdendritic regions. As-printed, the cellular and dendritic Mar-M 509 LPBF microstructures lead to the formation of continuous, fiber-like, eutectic carbide structures in the intercellular and interdendritic regions, which limit macroscopic ductility. Thermo-Calc is used for calculation of phase diagrams (CALPHAD) to estimate the equilibrium transformation temperatures of MC, M23C6, and M7C3-type carbides, which informs design of isothermal heat treatments to engineer microstructures with enhanced ductility over the as-printed or cast versions of Mar-M 509 while maintaining tensile strength. Scanning and transmission electron microscopy reveals the composition and distribution of carbide phases as a function of heat treatment temperature. Lastly, heat treatment recommendations for nozzle guide vanes are made.

description: We present a near-infrared spectroscopic study of a stellar mass selected sample of galaxies at z~1 utilising the LIRIS multi-object spectrograph on the WHT. We detect continuum, and the H alpha line for our sample, which is one of the better direct tracers of star formation in external galaxies. We spectroscopically measure the H alpha emission from 41 massive (M_{*}>10^{10.5} Msol) galaxies taken from the POWIR Survey with spectroscopic redshifts 0.410^{11} Msol which are detected in H alpha emission at z<0.9. We furthermore find that the fraction of galaxies with H alpha emission drops steadily and significantly with redder (U-B) colours at z~1, and that the SSFR drops with increasing (U-B) colour for galaxies at all masses. By investigating the SFR-mass relation we find that the SFR is roughly constant with mass, in possible contrast to previous work, and that the specific star formation rate (SSFR) is lower in the most massive galaxies. The scatter in the SFR vs. mass relationship is very small for those systems with ongoing star formation which suggests that star formation in the most massive galaxies at z~1 shuts off rather abruptly over <1 Gyr, without an obvious gradual decline. We furthermore investigate the SFR as a function of (U-B) colour divided into different mass bins, revealing a tracer of the epoch of transition from star forming to passive, as a form of star formation "downsizing". This suggests that the shut off of star formation occurs before the change in a galaxy's colour. We find that galaxy stellar mass is the primary driving mechanisms behind the star formation history for these galaxies and discuss several possible mechanisms for regulating this process.

description: Based on the differences between a spanning cluster and a wrapping cluster, an alternative criterion for testing wrapping percolation is provided for two-dimensional lattices. By following the Newman-Ziff method, the finite size scaling of estimates for percolation thresholds are given. The results are consistent with those from Machta's method.

Exogenous Data Analysis

description: Electrical power load forecasting defines strategies for utilities, power producers and individuals that participate in a smart grid. While it is well established in planning processes for production and utilities, the importance of accurate forecasting increases for individuals. The ongoing deregulation of the electricity market enables energy trading by individuals, requiring an accurate estimation of the production and consumption. Research on forecast for aggregated demand shows that including features for the forecast from sources, called exogenous, additional to the purely historical consumption data allows to obtain higher accuracy. In fact, their usage demonstrated to be able to explain the large variability observed in the power demand, taking into account the individual influences. Anyway, the influence of exogenous data is hardly investigated for individual forecasting, due to the minor prevalence of this analysis to date. This review shows the benefit of exogenous data usa ge and the necessity of detailed research on the input features and their influence on detailed, individual level, forecasts of power demand. Eventually, this contribution is concluded by the presentation of open issues and research directions for electric smart communities that the authors would like to address.

GAEA Action Equations Paradigm
Creators: name: Kaiser, Gail E.
name: Kaplan, Simon M.
Publisher: name: Columbia University
Year: 1988
Subjects: Computer science

description: This technical report consists of two papers describing the GAEA action equations paradigm. Incremental Dynamic Semantics for Language-based Programming Environments explains why attribute grammars are not suitable for expressing dynamic semantics and presents action equations, an extension of attribute grammars suitable for specifying the static and the dynamic semantics of programming languages. It describes how action equations can be used to generate language-based programming environments that incrementally derive static and dynamic properties as the user modifies and debugs the program. Rapid Prototyping of Concurrent Programming Languages extends this technology to a concurrent framework. It describes an (unimplemented) system that generates a parallel interpreter for the language and provides runtime support for the synchronization primitives and other facilities in the language.

description: We show that bound states moving in a finite periodic volume have an energy correction which is topological in origin and universal in character. The topological volume corrections contain information about the number and mass of the constituents of the bound states. These results have broad applications to lattice calculations involving nucleons, nuclei, hadronic molecules, and cold atoms. We illustrate and verify the analytical results with several numerical lattice calculations.
