description: In recent years, the use of robots in agriculture has been increasing mainly due to the high demand of productivity, precision and efficiency, which follow the climate change effects and world population growth. Unlike conventional agriculture, sugarcane farms are usually regions with dense vegetation, gigantic areas, and subjected to extreme weather conditions, such as intense heat, moisture and rain. TIBA - Tankette for Intelligent BioEnergy Agriculture - is the first result of an R&D project which strives to develop an autonomous mobile robotic system for carrying out a number of agricultural tasks in sugarcane fields. The proposed concept consists of a semi-autonomous, low-cost, dust and waterproof tankette-type vehicle, capable of infiltrating dense vegetation in plantation tunnels and carry several sensing systems, in order to perform mapping of hard-to-access areas and collecting samples. This paper presents an overview of the robot mechanical design, the embedded electronics and software architecture, and the construction of a first prototype. Preliminary results obtained in field tests validate the proposed conceptual design and bring about several challenges and potential applications for robot autonomous navigation, as well as to build a new prototype with additional functionality.

Bicycle Share’s Effect on UBC Property Trust Residential Bicycle Storage
Creators: name: Reisman, Sean
Publisher: name: The University of British Columbia
Year: 2019

description: This project, Bicycle Share’s Effects on the UBC Property Trust Residential Bike Storage, is a student-led collaboration with SEEDS, Campus and Community Planning, and UBC Properties Trust. E3 Eco Group was also involved in this project as the consultant working on behalf of UBCPT. The goal of this project was to determine the effects, if any, the Campus Bike Share program has had on the UBC Property Trusts class I and class II bicycle storage facilities since the start of the bike share pilot project. Ultimately, the findings from this project will generate recommendations for UBCPT and provide recommendations for the Bicycle Parking section of the REAP guidelines and the UBC Development Handbook. To meet this objective, the following methods were used 1. Literature Review focusing on current design guidelines in other cities with Bikeshare 2. GIS Analysis to get a better understanding of trips starting and ending in UBC Neighbourhoods 3. Resident Survey to get an understanding of how UBCPT residents are affected by the Bike Share Program. Disclaimer: “UBC SEEDS provides students with the opportunity to share the findings of their studies, as well as their opinions, conclusions and recommendations with the UBC community.

description: In the rapidly progressing field of organometal halide perovskites, the dimensional reduction could open up new opportunities for device applications. Herein, taking the recently synthesized trimethylsulfonium lead triiodide (CH$_3$)$_3$SPbI$_3$ perovskite as a representative example, we carry out first-principles calculations and study the nanostructuring and device application of halide perovskite nanowires. We find that the one-dimensional (1D) (CH$_3$)$_3$SPbI$_3$ structure is structurally stable, and the electronic structures of higher-dimensional forms are robustly determined at the 1D level. Remarkably, due to the face-sharing [PbI$_6$] octahedral atomic structure, the organic ligand-removed 1D PbI$_3$ frameworks are also found to be stable. Moreover, the PbI$_3$ columns avoid the Peierls distortion and assume a semimetallic character, contradicting the conventional assumption of semiconducting metal-halogen inorganic frameworks. Adopting the bundled nanowire junctions consisting of (CH$_3$)$_3$SPbI$_3$ channels with sub-5 nm dimensions sandwiched between PbI$_3$ electrodes, we finally obtain high current densities and large room-temperature negative differential resistance (NDR). It will be emphasized that the NDR originates from the combination of the near-Ohmic character of (CH$_3$)$_3$SPbI$_3$-PbI$_3$ contacts and a novel NDR mechanism that involves the quantum-mechanical hybridization between channel and electrode states. Our work demonstrates the great potential of low-dimensional hybrid perovskites toward advanced electronic devices beyond actively-pursued photonic applications.

description: Carbapenem-resistant Gram-negative bacteria isolated in Venezuela have been poorly characterized. The present study characterized a total of 34 isolates obtained from 27 patients; five of these patients were multi-infected. The bacterial species identified were Klebsiella pneumoniae (17), Pseudomonas aeruginosa (9), and Acinetobacter baumannii (8). From these isolates, 85% were identified as carbapenemase-producing bacteria, and the identified carbapenemase genes were blaKPC-2 (10/29 [34.4%]), blaVIM-type (7/29 [24.1%]), blaOXA-23 (7/29 [24.1%]), blaNDM-1 (8/29 [27.5%]), and the coexistence of blaOXA-23/blaNDM-1 (2/29 [6.8%]). Patient 1 was multi-infected by K. pneumoniae ST11 and ST2413 isolates harbouring the blaNDM-1 and blaKPC-2 genes, respectively. The other patients were multi-infected by two or three different bacterial species such as ESBL-producing K. pneumoniae isolates, P. aeruginosa harbouring the blaVIM-type gene, K. pneumoniae ST147 harbouring the blaKPC-2 gene and by A. baumannii harbouring the blaOXA-23 gene. The blaNDM-1 gene in A. baumannii is flanked by an uncommon genetic structure, whereas blaNDM-1 gene in K. pneumoniae revealed a common structure described in different plasmids from Enterobacteriaceae isolates. This study provides new information about the epidemiology of carbapenemase-producing bacteria in clinical setting in Venezuela.

Window for Peace: Determinants of Third-Party Guarantees in Intrastate Conflict Resolution

description: The literature on civil war termination has argued that comprehensive peace agreements and third-party guarantees that provide verification, support, or enforcement of agreement implementation contribute to the successful settlement of civil wars. Yet, there is to date no systematic study of the complex process by which guarantees are first given and then fulfilled while accounting for the strategic context within which this process occurs. This dissertation explores how potential guarantors’ perceptions of their own and of the conflict parties’ interests and means influence whether and what type of guarantee they give.
      	I show that a guarantor’s interests and capacity as well as its expectations of the conflict parties’ commitment problems and preferences affect its decision to give a specific type of guarantee in support of intrastate conflict resolution. In particular, a potential guarantor’s material and structural capacity determines the type of guarantee they are likely to give. In addition, a potential guarantor’s perception that the conflict parties prefer a negotiated settlement over continued fighting increases its expectations of a successful guarantee and thus makes a guarantee more likely.
               I test the theoretical hypotheses using statistical analysis, case study research, and in-depth interviews. The dissertation contributes to a better understanding of when and what types of third-party guarantees are given with the aim of supporting the successful implementation of peace agreements to end civil conflict. My findings provide a foundation for subsequent research on the effects of third-party guarantees on the peace process.

description: The controlled-not gate and the single qubit gates are considered elementary gates in quantum computing. It is natural to ask how many such elementary gates are needed to implement more elaborate gates or circuits. Recall that a controlled-U gate can be realized with two controlled-not gates and four single qubit gates. We prove that this implementation is optimal if and only if the matrix U satisfies the conditions tr U != 0, tr UX != 0, and det U != 1. We also derive optimal implementations in the non-generic cases.

Wind Resource Assessment for Utility-Scale Clean Energy Project: The Case of Sao Vicente Island

description: Accurate wind resource assessment is of high importance in wind power project development. This thesis estimates the annual energy yield and emission reduction potential for a grid connected 5.95 MW wind power plant at the island of Sao Vicente in Cape Verde. Wind speed data from Sao Vicente wind farm is processed and analyzed in R (Statistical software). The maximum annual wind energy potential at the site is 53,470.2 MWh, but analysis shows that the turbine can harness an estimated 14,185 MWh per annum. The estimated annual greenhouse gas (GHG) emissions displacement is 10,071 tonnes of CO2. In monetary terms, the GHG displacement is worth € 60,428 per annum based on the European trading system of € 6 per tonne CO2. The estimated investment cost of the 5.95MW wind power project is € 15.5 million against the estimated investment cost of similar project in Germany of € 10 million based on the investment benchmark of $ 1,800/kW published by the Fraunhofer Institute and also in comparison with a typical Vestas wind turbine cost of $1,800/kW. The difference in investment cost between Cape Verde and Germany is attributed to additional cost of breaking the complex terrain barriers to the good wind site in Sao Vicente; importation of turbine and equipment parts; foreign consultancy services and manpower; pre-feasibility and feasibility studies to identify suitable sites. With the prevailing electricity tariff of € 0.28 per kWh in Cape Verde, it was estimated that the wind power project will break-even within 4 years with or without carbon credit. This indicates that the project is financially viable. In the context of Nigeria’s coastal area of Lagos, wind resource potential lies within Class 1 (<5 m/s) at a hub height of 74 metres. This indicates that wind power project could be realized using a turbine with a cut-in speed below 3 m/s in best case scenario. The implication is that more numbers of small wind turbines will be needed to reach utility-scale.

description: We measure the bar properties (length, strength, and corotation radius) of a sample of barred low surface brightness (LSBs) galaxies and compare to previous results for both LSBs and high surface brightness galaxy (HSBs) samples. In addition, we present new optical $\textit{B}$- and $\textit{I}$-band surface brightness profiles, magnitudes, and colours. We find that bars in LSBs are shorter and weaker when compared with those in HSBs galaxies. Based on analysis of four different bar length measures on simulated galaxy images, we find our bar length measure based on azimuthal light profiles is the most accurate out of the four tested here when seeing effects are taken into account. We also find that bars in LSBs have comparable relative bar pattern speeds to those in HSBs, the majority of which we find to be `fast' (i.e. $\mathcal{R} 0.5$).

description: Many aspects of biology depend on the ability of DNA-binding proteins to locate specific binding sites within the genome. This search process is required at the beginning of all site-specific protein-DNA interactions, and has the potential to act as the first stage of biological regulation. Given the difficulty of pinpointing a small region of DNA, within even simple genomes, it is expected that proteins are adapted to use specialized mechanisms, collectively referred to as facilitated diffusion [Berg et al., 1981], to effectively reduce the dimensionality of their searches, and rapidly find their targets. Here, we use a combination of nanofabricated microfluidic devices and single-molecule microscopy to determine whether facilitated diffusion contributes to all DNA target searches. We investigate promoter binding by E. coli RNA polymerase, foreign DNA recognition by CRISPR-Cas complexes, and Rad51’s homology search during recombination. In each example, we observe that the target searches proceed without extensive use of facilitated diffusion; rather, consideration of these non-facilitated target searches reveals an alternative search strategy. We show that instead of reducing the dimensionality of their searches, these proteins, reduce search complexity by minimizing unproductive interactions with DNA, thereby increase the probability of locating a specific DNA target.

description: The present study aims to bring into focus the antinomian doctrine of redemption through sin as it appears in Jules Michelet’s La Sorcière. According to Michelet, the witch-cult was both vestigial paganism and an attempt at overthrowing the Christian political order. The witch redeemed mankind by sinning against the Christian order, thus anticipating the Renaissance and the Enlightenment, as well as the French Revolution. The notion of redemption through sin, borrowed from Gershom Scholem, will enable us to compare Michelet’s and Scholem’s approaches to history and counter-history. It will also allow us to read La Sorcière against a broader religious background than is usually employed. Among the sources of Michelet, the often overlooked kabbalistic, possibly Sabbatian, subtext will be assessed in relation to his peculiar female messianism. Likewise, the episode, in La Sorcière, of the encounter between the witch and the Jew will be thoroughly studied. This may lead us to better comprehend Michelet’s theology, with the biblical God being akin, in his opinion, to that of the witches.

description: We study the dynamics of a self-gravitating scalar field solitonic object (boson star) in the Jordan-Brans-Dicke (BD) theory of gravity. We show dynamical processes of this system such as (i) black hole formation of perturbed equilibrium configuration on an unstable branch; (ii) migration of perturbed equilibrium configuration from the unstable branch to stable branch; (iii) transition from excited state to a ground state. We find that the dynamical behavior of boson stars in BD theory is quite similar to that in general relativity (GR), with comparable scalar wave emission. We also demonstrate the formation of a stable boson star from a Gaussian scalar field packet with flat gravitational scalar field initial data. This suggests that boson stars can be formed in the BD theory in much the same way as in GR.

description: We formulate the Jost function formalism based on the Hartree-Fock-Bogoliubov (HFB) theory which has been used to represent the nature of the superfluidity of nucleus. The Jost function based on the HFB can give the analytic representation of the S-matrix for the nucleon elastic scattering targeting on the open-shell nucleus taking into account the pairing effect. By adopting the Woods-Saxon potential, we show the numerical results of S-matrix poles and their trajectories with varying the pairing strength in two cases of Fermi energies. The total cross sections in each cases for neutron elastic scattering are also analyzed, and we confirmed some staggering shapes or sharp resonances originated from the effect of pairing can be seen in the cross section.

Publisher: name: Columbia University

Subjects: Glass manufacture
Cultural property--Protection

description: This thesis seeks to provide greater meaning and significance to wire glass so that it may be preserved by exploring the historical origins and complexity of manufacture of the medium. The Industrial Revolution was a period of amazing evolution in the history of glass manufacture. Plate glass technology allowed for new design and building construction concepts, including the Crystal Palace, but this was an imperfect technology. As the brilliant minds of the Revolution struggled to grapple with the obstacles posed by plate glass, wire glass was eventually born. This new glass type spread across the United States in subsequent years, fueled by uniform manufacture standards on the city and state levels and the American mass media’s coverage of conflagrations, which led to the public’s association of wire glass with safety given its fire retardant and shatterproof qualities. Wire glass was technically incredibly difficult to produce, especially in mass production, and although inventors experimented with various treatments and patterns, wire glass remained and was comparatively expensive (though people generally believed the safety benefits outweighed the costs). Wire glass fell into disfavor during the World Wars as it was replaced by newer types of glass that were more economical, but recent trends have sparked renewed interest in the use and hence preservation of wire glass. Original methods of wire glass manufacture using early wire netting patterns no longer exist, and so current methods of preservation and conservation involving replication through glass lamination methods using imported wire nettings and salvage are discussed. Possible conservation treatments for repair are debated and further research is concluded.

description: Three-types (three-band, two-band and one-band) of effective Hamiltonians for the HgBa$_2$CuO$_4$ and three-band effective Hamiltonian for La$_2$CuO$_4$ are derived beyond the level of the constrained-GW approximation combined with the self-interaction correction (cGW-SIC) derived in Hirayama et al. Phys. Rev. B 98, 134501 (2018) by improving the treatment of the interband Hartree energy. The charge gap and antiferromagnetic ordered moment show good agreement with the experimental results when the present effective Hamiltonian is solved, indicating the importance of the present refinement. The obtained Hamiltonians will serve to clarify the electronic structures of these copper oxide superconductors and to elucidate the superconducting mechanism.

Dynamic wormholes, anti-trapped surfaces, and energy conditions

Year: 1998

description: Adapting and extending a suggestion due to Page, we define a wormhole throat to be a marginally anti-trapped surface, that is, a closed two-dimensional spatial hypersurface such that one of the two future-directed null geodesic congruences orthogonal to it is just beginning to diverge. Typically a dynamic wormhole will possess two such throats, corresponding to the two orthogonal null geodesic congruences, and these two throats will not coincide, (though they do coalesce into a single throat in the static limit). The divergence property of the null geodesics at the marginally anti-trapped surface generalizes the ``flare-out'' condition for an arbitrary wormhole. We derive theorems regarding violations of the null energy condition (NEC) at and near these throats and find that, even for wormholes with arbitrary time-dependence, the violation of the NEC is a generic property of wormhole throats. We also discuss wormhole throats in the presence of fully antisymmetric torsion and find that the energy condition violations cannot be dumped into the torsion degrees of freedom. Finally by means of a concrete example we demonstrate that even temporary suspension of energy-condition violations is incompatible with the flare-out property of dynamic throats.

description: The patterns of reversible changes in the critical current and discrete current states of a structure in the form of a superconducting quantum interferometer shunted by superconducting inductance, as a result of passing an alternating transport current through the structure and applying an external alternating magnetic field simultaneously with a direct transport current, was established. A new type of discrete stationary state was discovered during the transition of the interferometer to the resistive state caused by the combined action of direct and alternating transport currents.

description: In this note we have compared two different perturbation techniques that could be used to generate solutions of Einstein's equations in presence of negative cosmological constant. One of these two methods is derivative expansion and the other is an expansion in inverse powers of dimension. Both the techniques generate space-time with a singularity shielded by a dynamical event horizon. We have shown that in the appropriate regime of parameter space and with appropriate choice of coordinates, the metrics and corresponding horizon dynamics, generated by these two different techniques, are exactly equal to the order the solutions are known both sides. This work is essentially extension of \cite{prevwork} where the authors have shown the equivalence of the two techniques up to the first non-trivial order.

Wireless Corrosion Monitoring for Reinforced Concrete Structures and Concrete Repair

description: Substantial efforts are put in preservation projects, but often little care is given once the project is finished. How do we know when we need to go back and repair the building again? A long-term monitoring system can provide invaluable information about the conditions of a building and building materials. Such information may help owners, architects, engineers and conservators to understand what the cause of the problem is, when and where the repair is needed, and what type of intervention is necessary. This can help prevent small problems from becoming large problems. This thesis will evaluate wireless monitoring systems for reinforced concrete structures. Using wireless sensors as monitoring devices is not a new technique. In fact, there are already several wireless sensors being used to monitor various types of structures, materials and conditions. However, most of the existing wireless sensors have short service lives due to limited battery capacity and issues with durability. This thesis research focuses on prototyping and evaluating a wireless and battery-less sensing device named Intelligent Aggregate (IA) and Intelligent Aggregate System (IAS). Intelligent Aggregate is based on the technology of passive RFID (Radio Frequency Identification) tags, which can wirelessly communicate with RFID readers through Ultra High Frequency (UHF) electromagnetic waves emitted from the readers. There are several advantages of using RFID devices over existing battery powered wireless sensors, which are bulky in size due to batteries and expensive to maintain due to the need to retrieve the sensors for occasional battery change. On the other hand, IA can operate as long as they can harvest energy from the RFID reader. Another advantage of using IA is the ability to easily and inexpensively build Wireless Sensing Networks (WSNs). By strategically deploying hundreds or thousands, if necessary, wireless sensing devices in a building, we can collect extensive information about the condition of buildings and materials in real-time. Such information would greatly help us to wisely use time, money, and other resources.

description: The transient response of a stationary state of a quantum particle in a step potential to an instantaneous change in the step height (a simplified model for a sudden bias switch in an electronic semiconductor device) is solved exactly by means of a semianalytical expression. The characteristic times for the transient process up to the new stationary state are identified. A comparison is made between the exact results and an approximate method.

description: This narrative inquiry documents the inaugural Performance at the Center summer institute, a professional development program in which teachers worked alongside students to generate an original multimodal performance piece inspired by Mary Shelley’s Frankenstein. Specifically, the study examines text-inspired creation: how readers identify and then create out of the gaps and spaces in a given text through remix and performance. This researcher employs qualitative methods to address the following questions: (1) How do Performance at the Center facilitators set up the conditions for text-inspired creation? (2) How do teacher and student players describe what effect, if any, Performance at the Center has on their reading of Frankenstein? and (3) How do select teacher players describe what effect, if any, Performance at the Center has had on their design and implementation of curriculum? Examining her data through the lens of “the gift” (Marcel Mauss and Lewis Hyde), this researcher finds that facilitators set up the conditions for text-inspired creation by stepping into the role of muse—offering both tangible and intangible “gifts” to prompt production. Teachers and students describe the ways in which Performance at the Center invites sensory entry into Shelley’s text, enabling readers to compose meanings potentially inaccessible through words alone. Select teachers describe the ways in which Performance at the Center catalyzes a reconceptualization of what it means to teach literature, underscoring as it does the profound distinction between dissecting a text and experiencing a text. This investigation suggests that positioning the study of literature within a gift culture—receiving literature as a living gift to be passed on through student text-inspired creation—has the potential revitalize texts, teachers and the classroom itself.
First-Principle Study of Phosphine Adsorption on Si(001)-2$\times$1-Cl

description: This paper presents a DFT study for phosphine adsorption on a Si(001)-2$\times$1 surface covered by a chlorine monolayer, including adsorption on local defects, i.e. mono- and bivacancies in the adsorbate layer (Cl, Cl$_2$), and combined vacancies with removed silicon atoms (SiCl, SiCl$_2$). Activation barriers were found for the adsorbing PH$_3$ to dissociate into PH$_2$+H and PH+H$_2$ fragments; it was also established that phosphine dissociation on combined vacancies is possible at room temperature. If there is a silicon vacancy on the surface, phosphorus settles in the Si(001) lattice as PH (if the vacancy is SiCl) or as PH$_2$ (if the vacancy is SiCl$_2$). This paper suggests a method to plant a separate phosphorus atom into the silicon surface layer with atomic precision, using phosphine adsorption on defects specially created on a Si(001)-2$\times$1-Cl surface with an STM tip.

description: In the No-Boundary Universe a primordial black hole is created from a constrained gravitational instanton. The black hole created is immersed in the de Sitter background with a positive cosmological constant. The constrained instanton is characterized not only by the external parameters, the mass parameter, charge and angular momentum, but also by one more internal parameter, the identification period in the imaginary time coordinate. Although the period has no effect on the black hole background, its inverse is the temperature of the no-boundary state of the perturbation modes perceived by an observer. By using the Bogoliubov transformation, we show that the perturbation modes of both scalar and spinor fields are in thermal q equilibrium with the black hole background at the arbitrary temperature. However, for the two extreme cases, the de Sitter and the Nariai models, the no-boundary state remains pure.

Wolves at the Door: A Closer Look at Hedge Fund Activism

description: Some commentators attribute the success of certain hedge fund activism events to “wolf pack” activism, the support offered by other investors, many of whom are thought to accumulate stakes in the target firms before the activists’ campaigns are publicly disclosed. This paper investigates wolf-pack activism by considering the following questions: Is there any evidence of wolf-pack formation? Is the wolf pack formed intentionally (by the lead activist) or does it result from independent activity by other investors? Does the presence of a wolf pack improve the activist’s ability to achieve its stated objectives? First, I find that investors other than the lead activist do in fact accumulate significant share-holdings before public disclosure of activists’ campaigns, a result consistent with wolf-pack formation. Second, these share accumulations are more likely to be mustered by the lead activist rather than occurring spontaneously. Notably, for example, the other investors are more likely to be those who had a prior trading relationship with the lead activist. Third, the presence of a wolf pack is associated with a greater likelihood that the activist will achieve its stated objectives (e.g., will obtain board seats) and higher future stock returns over the duration of the campaign.

description: X-ray emission is an important indicator of stellar activity. In this paper, we study stellar X-ray activity using the XMM-Newton and LAMOST data for different types of stars. We provide a sample including 1259 X-ray emitting stars, of which 1090 have accurate stellar parameter estimations. Our sample size is much larger than those in previous works. We find a bimodal distribution of X-ray to optical flux ratio (log(fX/fV)) for G and K stars. We interpret that this bimodality is due to two subpopulations with different coronal heating rates. Furthermore, using the full widths at half maxima calculated from Hα and H\b{eta} lines, we show that these stars in the inactive peaks have smaller rotational velocities. This is consistent with the magnetic dynamo theory that stars with low rotational velocities have low levels of stellar activity. We also examine the correlation between log(fX/fV) and luminosity of the excess emission in the Hα line, and find a tight relation between the coronal and chromospheric activity indicators.
