Job analysis--Computer programs

description: We study three models of job scheduling in a distributed server system. For each of them we suggest scheduling algorithms that are computationally efficient and provably achieve a performance objective related to the model. For this we consider jobs to be an abstraction of executable programs that request specific resources e.g. memory, CPU. Resources need to be reserved in one of the servers for the duration the programs run, which is unknown. The first model considers queue-based scheduling algorithms, in which jobs belong to a finite set of types and each type has a separate queue. The scheduling objective under this formulation is to keep the size of all queues bounded, which translates to bounded queuing delay. The two families of algorithms for this model can achieve the objective for the maximum theoretical workload. Most importantly they follow vastly different paradigms and are both viable alternatives depending on what other trade-offs the scheduling has to achieve. The second model considers that resource requirements of jobs come from an unknown distribution. Jobs are queued and the objective is again to keep the number of jobs in the queue bounded and consequently the queuing delay. In this harder formulation there is no previous characterization of the maximum workload that can achieve the objective. We provide such a characterization and algorithms that achieve at least 2/3 of that maximum. Lastly, we consider a model without queues in which jobs are admitted or rejected on arrival, with the goal to maximize the total utility of the jobs that run. Algorithms of this model were proven to achieve at least 1/2 of the maximum, but further analysis suggests that this limit can be as high as 1 − e⁻¹. In all models we made simplifying assumptions that allow us to prove the desired properties of the system, but despite the theoretical nature of this work, we also discuss how the algorithms can be applied and tailored to the needs of different cloud applications. We hope they will eventually inspire improvements to existing cloud infrastructure management deployments.

description: We report direct detection of charge-tunneling between a quantum dot and a superconducting island through radio-frequency gate sensing. We are able to resolve spin-dependent quasiparticle tunneling as well as two-particle tunneling involving Cooper pairs. The quantum dot can act as an RF-only sensor to characterize the superconductor addition spectrum, enabling us to access subgap states without transport. Our results provide guidance for future dispersive parity measurements of Majorana modes, which can be realized by detecting the parity-dependent tunneling between dots and islands.

description: A combined experimental and theoretical study of very-low-energy electron diffraction at the (0001) surface of 2H-NbSe2 is presented. Electron transmission spectra have been measured for energies up to 50 eV above the Fermi level with k|| varying along the GammaK line of the Brillouin zone. Ab initio calculations of the spectra have been performed with the extended linear augmented plane wave k-p method. The experimental spectra are interpreted in terms of three-dimensional one-electron band structure. Special attention is paid to the quasi-particle lifetimes: by comparing the broadening of the spectral structures in the experimental and calculated spectra the energy dependence of the optical potential Vi is determined. A sharp increase of Vi at 20 eV is detected, which is associated with a plasmon peak in the Im(-1/epsilon) function. Furthermore, the electron energy loss spectrum and the reflectivity of NbSe2 are calculated ab initio and compared with optical experiments. The obtained information on the dispersions and lifetimes of the unoccupied states is important for photoemission studies of the 3D band structure of the valence band.

description: Silicon photonics accelerated the advent of complex integrated photonic systems where multiple devices and elements of the circuits synchronize to perform advanced functions such as beam formation for range detection, quantum computation, spectroscopy, and high-speed communication links. The key ingredient for silicon's growing dominance in integrated photonics is scalability: the ability to monolithically integrate large number of devices. There are emerging device designs and material platforms compatible with silicon photonics that offer performances superior to silicon alone, yet their lack of scalability often limits the demonstrations to device-level. Here we discuss two of such platforms, suspended air-cladded microresonators and graphene modulators. In this thesis, we demonstrate methods to scale these devices and enable more complex applications and higher performance than a single device can ever acheive. We present an effective method to thermally tune optical properties of suspended and air-cladded devices. We utilize released MEMs-like wire structures and integrated heaters and demonstrate efficient thermo-optic tuning of suspended microdisk resonators without affecting optical performance of the device. We further scale this method to a system of two evanescently coupled resonators and demonstrate on-demand control of their coupling dynamics. We present an approach to achieve large yield of high bandwidth graphene modulators to enable Tbits/s data transmission. Despite their high performance, graphene modulators have been demonstrated at single device-level primarily due to low yield, ultimately limiting their total data transmission capacity. We achieve large yield by minimizing performance variation of graphene modulators due to random inhomogeneous doping in graphene by optimizing device design and leveraging state-of-the-art electrochemical delamination graphene transfer. We present for the first time, to the best of our knowledge, a statistical analysis of graphene photonic devices. Finally, we present a graphene modulator that is versatile for photonic links at cryogenic temperature. We demonstrate the operation of high bandwidth graphene modulator at 4.9 K, a feat that is fundamentally challenging other electro-optic materials. We describe its performance enhancement at cryogenic temperature compared to ambient environment unlike modulators based on other electro-optic materials whose performance degrades at cryogenic temperature.

description: We investigate a class of exactly solvable quantum quench protocols with a finite quench rate in systems of one dimensional non-relativistic fermions in external harmonic oscillator or inverted harmonic oscillator potentials, with time dependent masses and frequencies. These hamiltonians arise, respectively, in harmonic traps, and the $c=1$ Matrix Model description of two dimensional string theory with time dependent string coupling. We show how the dynamics is determined by a single function of time which satisfies a generalized Ermakov-Pinney equation. The quench protocols we consider asymptote to constant masses and frequencies at early times, and cross or approach a gapless potential. In a right side up harmonic oscillator potential we determine the scaling behavior of the one point function and the entanglement entropy of a subregion by obtaining analytic approximations to the exact answers. The results are consistent with Kibble-Zurek scaling for slow quenches and with perturbation calculations for fast quenches. For cis-critical quench protocols the entanglement entropy oscillates at late times around its initial value. For end-critical protocols the entanglement entropy monotonically goes to zero inversely with time, reflecting the spread of fermions over the entire line. For the inverted harmonic oscillator potential, the dual collective field description is a scalar field in a time dependent metric and dilaton background.

description: Relativistic Cowling approximation in which all metric perturbations are omitted is applied to non-axisymmetric infinitesimal oscillations of uniformly rotating general relativistic polytropes. Frequencies of lower order f-modes which are important in analysis of secular instability driven by gravitational radiation are investigated and neutral points of the mode along equilibrium sequences of rotating polytropes are determined. Since this approximation becomes more accurate as stars are more relativistic and/or as they rotates more rapidly, we will be able to analyze how a rotation period of a neutron star may be limited by this instability. Possible errors in determining neutral points caused by omitting metric perturbations are also estimated.

Stories from a quarter century of cover system design : Learnings to inform the future
Creators: name: O'Kane, Mike
Publisher: name: The University of British Columbia
Year: 2024

description: For over twenty-five years, Okane has designed, built, and monitored cover systems for tailings storage facilities and mine rock stockpiles across British Columbia. Typical terminology within the industry refers to “water covers” and “dry covers”. Dry Covers, or cover systems that result in primarily a terrestrial ecosystem, is the focus of this paper. They are the building blocks for achieving future, or returning, land use, and providing a stable, reliable, and sustainable interface between a mine landform and the environment. With, primarily, a warm humid continental and oceanic climate, British Columbia is a unique environment for cover system design. Performance expectation, from a technical perspective, is strongly influenced by the geologic and hydrogeologic system at a mine site. Cover system performance itself is largely dictated by water management, freeze-thaw and wet-dry cycles, and storm events. Each site can also have many microclimates that will impact not just cover system performance but long-term revegetation potential. As new projects explore alternative waste disposal methods, including filtered tailings and codisposal options, modelling of both saturated and unsaturated zone hydrology will need to consider new land-climate interactions, including land use(s) that are not solely focussed on achieving ecological restoration. Risk-based decisions, informed by geochemical stability will have a greater impact on geotechnical stability; closure criteria requirements for cover systems will evolve. There also remains a need for specific focus on the key aspects influencing cover system functionality to communicate, on a site-specific basis, that cover systems are ‘proven technology’, as defined by the Province’s Technical Readiness Assessment (TRA) guidance, to manage water and water quality risk. This paper highlights key considerations for designing cover systems in British Columbia, historical lessons learned, and factors to consider when designing for future climate change scenarios.

description: Fisheries are among the most complex and tightly coupled social-ecological systems.  This thesis develops new perspectives on the spatial features of fisheries, and on common pool resources in general.  The central model of the work is the Distributed Commons, a commons spread across space with local and cross-boundary interactions.  The model is founded in evidence from historical analysis and complexity theory, and offers insights for management and broader sustainable development policy.  The second part of the thesis uses empirical analysis, applying Bayesian and econometric techniques, to study the spatial features exposed by the model.  Finally, a computational model is calibrated for exploring the consequences of this theory through experiments.  The implications of the Distributed Commons model are relevant to many areas of sustainable development, including atmospheric pollution, environmental degradation, and the use of ecosystem resources.

description: Recent experiments on unzipping of RNA helix-loop structures by force have shown that about 40-base molecules can undergo kinetic transitions between two well-defined `open' and `closed' states, on a timescale = 1 sec [Liphardt et al., Science 297, 733-737 (2001)]. Using a simple dynamical model, we show that these phenomena result from the slow kinetics of crossing large free energy barriers which separate the open and closed conformations. The dependence of barriers on sequence along the helix, and on the size of the loop(s) is analyzed. Some DNAs and RNAs sequences that could show dynamics on different time scales, or three(or more)-state unzipping, are proposed.

Capability of Tokai Strainmeter Network to Detect and Locate a Slow Slip: First Results

subject: FOS: Physical sciences

description: The Tokai Strainmeter Network (TSN), a dense network deployed in the Tokai region, which is the easternmost region of the Nankai trough, has been designed to monitor slow slips that reflect changes in the coupling state of the plate boundary. It is important to evaluate the current capability of TSN to detect and locate slow slips. For this purpose, the probability-based magnitude of completeness developed for seismic networks was modified to be applicable to the evaluation of TSN's performance. Using 35 slow slips having moment magnitudes M5.1-5.8 recorded by TSN in 2012-2016, this study shows that the probability that TSN detected and located a M5-class slow slip is high (> 0.9) when considering a region in and around the TSN. The probability has been found to depend on the slip duration, especially for M5.5 or larger, namely the longer the duration, the lower the probability. A possible use of this method to assess the network's performance for cases where virtual stations are added to the existing network was explored. The use of this application when devising a strategic plan of the TSN to extend its coverage westwards is proposed. This extension that allows TSN to cover the entire eastern half of the Nankai trough is important, because the historical records show that the eastern half of this trough tends to rupture first.

description: RESUMEN La resistencia de las plantas a las bajas temperaturas es el producto de una selección natural en este sentido. Los principales factores que influyen en la susceptibilidad al frío son la protección física de la planta y la capacidad de no colapsarse bioquimicamente. Dicha capacidad es definida especialmente por la composición de la bicapa lipídica de las membranas, y por la aptitud para anular los efectos de los agentes oxidantes y radicales libres. Es interesante la aplica-ción de clormequat para combatir los efectos del frío.

ABSTRACT Revision of the cold damages in plants: Avocado tree. The resistance of plants at low-temperatures is a result of natural selection. The mean factors that influence their susceptibility to cold are the plant's physical protection and the capacity to avoid a biochemical collapse. This capacity especially depends on the composition of double lipid layer of membranes, and the ability to nullify the effects of oxidant agents and free radicals. The aplication of chlormequat to reduce the effects of cold is recommended.
Scanning Tunneling Microscopy Studies of Charge Density Waves in NbSe₂  and muSR studies of  Nickel doping in BaFe₂As₂
Creators: Arguello, Carlos Jose
Publisher: name: Columbia University
Year: 2014
Subjects: Condensed matter

description: Scanning Tunneling Microscopy is a very powerful technique to study electronic properties of condensed matter systems at the nanoscale.  Part I of this thesis describes my work on Charge Density Waves (CDW) in NbSe₂. NbSe₂ is a layered dichalcogenide that has a CDW phase below 33K.
      We describe our study of the phase transition from the normal phase to the CDW phase at atomic scales.  This is more relevant in light of recent discoveries of charge order in cuprates.  Brand new research has shed some light  about  the relationship between the pseudogap phase, charge order and superconductivity in cuprates. The behavior of the CDW phase in NbSe₂ described in chapter 3 is strongly reminiscent of this physics of cuprates. NbSe₂ is an excellent test bed for the study of the effect of impurities in correlated phases.
      In chapter 4 we revisit the cause of CDW formation in NbSe₂. By including a very dilute concentration of impurities,  we obtain information of the electronic bands of the material in the CDW phase. Based on this information, we are able to discuss the relationship between nesting, electron-phonon coupling and CDW in NbSe₂. We demonstrate that by combining quasiparticle interference data with additional knowledge of the quasiparticle band structure from angle resolved photoemission measurements, one can extract the wavevector and energy dependence of the important electronic scattering processes.
      Part II focuses on Muon Spin Rotation and its application to the study of high-Tc superconductors. We describe our muSR studies on Nickel doped BaFe₂As₂. By analyzing several doping concentrations, we explore the phase diagram in the antiferromagnetic and in the superconducting phases. This discussion also includes a detailed discussion of a doping concentration which falls in-between the AF and the SC phase.

Auf der Basis aktueller Forschung sollen bereits in wenigen Jahren in manchen Ländern sogar Übertragungssysteme eingeführt werden, die die erste Generation des nun schon beinahe "klassischen" Digitalfernsehens ablösen können und den theoretischen Grenzen der Übertragungseffizienz so nahe kommen, dass noch weitergehende Verbesserungen dann nicht mehr möglich sein werden (DVB-S2, DVB-C2, DVB-T2).
Der Vortrag zeigt diese Entwicklungen auf, erläutert die technischen Hintergründe und analysiert die Perspektiven der Markteinführung.

description: We have studied the kinetic roughening of an oil--air interface in a forced imbibition experiment in a horizontal Hele--Shaw cell with quenched disorder. Different disorder configurations, characterized by their persistence length in the direction of growth, have been explored by varying the average interface velocity v and the gap spacing b. Through the analysis of the rms width as a function of time, we have measured a growth exponent beta ~= 0.5 that is almost independent of the experimental parameters. The analysis of the roughness exponent alpha through the power spectrum have shown different behaviors at short (alpha_1) and long (alpha_2) length scales, separated by a crossover wavenumber q_c. The values of the measured roughness exponents depend on experimental parameters, but at large velocities we obtain alpha_1 ~= 1.3 independently of the disorder configuration. The dependence of the crossover wavenumber with the experimental parameters has also been investigated, measuring q_c ~ v^{0.47} for the shortest persistence length, in agreement with theoretical predictions.

description: Gravel-bed biochemical reactor (GBBR) water treatment technology is rapidly advancing for mining applications in Canada. While the GBBR technology has a technology readiness level (TRL) of 8 for several constituents, the TRL can decrease with site-specific considerations. This presentation details the sitespecific TRL advancement of Maven’s mBio GBBR technology for the Copper Mountain Mine in BC. The COPCs include nitrate, selenium, molybdenum, copper, sulphate, and uranium. The technology maturation plan (TMP) included on-site testing of pilot-scale GBBRs with mFlex units paired with column trials at Maven’s climate-controlled facilities. Multiple conditions and scenarios were tested to inform on potential operational risks and identify appropriate controls and management strategies. The testing program included varying conditions, such as altering flow rates, temperatures, and reagent dosages to assess optimal operational parameters. Reagent dosing was optimized depending on potential future variations of water chemistries and flows. Additional modifications to reagents and amendments were tested to the enhanced treatment of selenium and molybdenum. The findings from this trial confirmed the extent and rates of treatment of the targeted constituents, as well as their final fate and distribution in the GBBR. This GBBR technology is now at a site-specific TRL-7, ready for on-site demonstration and advancement to TRL-8.

description: Motivated by the recent achievement of space-based Bose-Einstein condensates (BEC) with ultracold alkali-metal atoms under microgravity and by the proposal of bubble traps which confine atoms on a thin shell, we investigate the BEC thermodynamics on the surface of a sphere. We determine analytically the critical temperature and the condensate fraction of a noninteracting Bose gas. Then we consider the inclusion of a zero-range interatomic potential, extending the noninteracting results at zero and finite temperature. Both in the noninteracting and interacting cases the crucial role of the finite radius of the sphere is emphasized, showing that in the limit of infinite radius one recovers the familiar two-dimensional results. We also investigate the Berezinski-Kosterlitz-Thouless transition driven by vortical configurations on the surface of the sphere, analyzing the interplay of condensation and superfluidity in this finite-size system.

The Hubble Diagram of Type Ia Supernovae in Non-Uniform Pressure Universes

description: We use the redshift-magnitude relation, as derived by Dcabrowski (1995), for the two exact non-uniform pressure spherically symmetric Stephani universes with the observer positioned at the center of symmetry, to test the agreement of these models with recent observations of high redshift type Ia supernovae (SNIa), as reported in Perlmutter et al. (1997). By a particular choice of model parameters, we show that these models give an excellent fit to the observed redshifts and (corrected) B band apparent magnitudes of the SNIa data, but for an age of the Universe which is typically about two Gyr greater than in the corresponding Friedmann model. Based on a value of $H_0 \sim 65$ and assuming $Λ\geq 0$, the P97 data implies a Friedmann age of at most 13 Gyr and in fact a best-fit (for $q_0 = 0.5$) age of only 10 Gyr. Our Stephani models, on the other hand, can give a good fit to the P97 data with an age of up to 15 Gyr and could, therefore, significantly alleviate the conflict between recent cosmological and astrophysical age predictions. The choice of model parameters is quite robust: one requires only that the non-uniform pressure parameter, $a$, in one of the models is negative and satisfies $|a| \lte$ 3 km$^2$ s$^{-2}$ Mpc$^{-1}$. By allowing slightly larger, negative, values of $a$ one may `fine tune' the model to give an even better fit to the P97 data.

Schematic Effects on Probability Problem Solving

description: Three studies examined context effects on solving probability problems. Variants of word problems were written with cover stories which differed with respect to social or temporal schemas, while maintaining formal problem structure and solution procedure. In the first of these studies it was shown that problems depicting schemas in which randomness was inappropriate or unexpected for the social situation were solved less often than problems depicting schemas in which randomness was appropriate. Another set of two studies examined temporal and causal schemas, in which the convention is that events are considered in forward direction. Pairs of conditional probability (CP) problems were written depicting events E1 and E2, such that E1 either occurs before E2 or causes E2. Problems were defined with respect to the order of events expressed in CPs, so that P(E2|E1) represents the CP in schema-consistent, intact order by considering the occurrence of E1 before E2, while P(E1|E2) represents CP in schema-inconsistent, inverted order. Introductory statistics students had greater difficulty encoding CP for events in schema-inconsistent order than CP of events in conventional deterministic order. The differential effects of schematic context on solving probability problems identify specific conditions and sources of bias in human reasoning under uncertainty. In addition, these biases may be influential when evaluating empirical findings in a manner similar to that demonstrated in this paper experimentally, and may have implications for how social scientists are trained in research methodology.

description: Due to the protracted nature of forced displacement, a majority of refugees spend their entire academic cycles in exile (Milner & Loescher, 2011). While some successfully navigate their educational trajectories, others are unable to complete basic education. Despite the important role education plays in emergency, displacement, and resettlement, refugee education remains under-researched. There is a dearth of research that has investigated what factor(s) at individual, family, and school levels contribute to children and youth’s school persistence and dropout amidst displacement. This study aimed to fill this substantial gap in the literature by taking a balanced, comprehensive approach to investigate the experiences of children and youth in Kakuma Refugee Camp in Kenya. Using a sequential mixed-methods design, this study examined the different factors that influenced the schooling of children and youth in Kakuma Refugee Camp. This study found that family poverty, inability to afford school uniforms and supplies, school uniform policy, living without parents/guardians, and family responsibilities were some of the major reasons that contributed to school dropout. By contrast, different types of support—financial, emotional, or academic—received from family members, teachers, and peers mainly influenced students’ persistence, despite persistent barriers in schooling. This study finds that ensuring educational access and persistence was not the role of a single stakeholder in education—i.e., a family member (parent), a head teacher, a teacher, or a student. Instead, different actors in children and youth’s sociocultural environments could play a role in influencing their decisions to (dis)continue education. The findings from this study not only contribute to expanding the knowledge base of education in emergencies, but they also support educators and practitioners who are providing and improving education for displaced populations, as well as policymakers within the Ministry of Education working to strengthen education systems and to foster access to quality education. My research findings may also prove meaningful in understanding the school persistence of school-aged children and youth in other refugee-hosting countries around the world, including the United States, and other mobile and marginalized populations in non-conflict settings.
