New reclamation standards for oil & gas well sites and pipelines in the agricultural land reserve
Creators: name: Jones, Peter
Publisher: name: The University of British Columbia
Year: 2009

description: All uses of land by the petroleum industry in British Columbia s Agricultural Land Reserve are subject to the Agricultural Land Commission Act and require the approval of the Commission. The Agricultural Land Commission adopted General Order 293/95 on April 10, 1995, and the requirements of this Order are now in effect. The purpose of General Order 293/95 is to streamline existing regulations and to clarify reclamation standards. The General Order will allow some oil and gas developments to proceed without making an application to the Commission, as long as the conditions of the Order are adhered to. The reclamation standards which have been adopted are similar to requirements currently in place in northwestern Alberta because similar landforms, soils, and land uses exist in the Peace River region of BC. In addition, adopting similar requirements provides consistency for the industry between adjacent jurisdictions, and allows BC to benefit from the years of experience and consultation with the petroleum industry which has occurred in Alberta. General Order 293/95 applies only to land in the ALR contained in the Peace River Regional District and the Fort Nelson-Liard Regional District.

description: The study investigated the responses of State governments to change in fiscal policy between 1999 and 2017. The methodology employed in the study involves the use of Generalized Method of Moments (GMM) to estimate the cyclical fiscal policy which is a reflection of the systematic response of the fiscal balance of state governments to the regulatory quality of the institution of States. The results show that the fiscal institutions are rather weak and may actually also form part of the rent-seeking agents in the fiscal space as it engenders procylical fiscal policy at the second tier of government in Nigeria. The empirical findings of this study conclude that fiscal policy of State governments in Nigeria is highly procyclical. The study recommends active government intervention in the economy through the use of appropriate macroeconomic policies such as expansionary fiscal policy during the period of fiscal crunch and contractionary fiscal policy during the period of boom.

description: Emotion is difficult to define, quantify, and measure yet it pervades almost all aspects of an individual’s life, from one’s internal motivations and feelings, to his or her external responses and decisions. This body of work tackles three major components contributing to the experience of emotion – development, social influences, and the underlying role of the brain. These three components shape emotion in a fundamental and intertwining way, and methods like brain imaging can provide new insights into how emotion changes and is expressed throughout one’s life. Study 1 showed that reactivity and regulation of craving changes with age and are supported by frontoparietal cortical maturation. Study 2 showed that the value estimations of food change across development and can be heavily influenced by social factors. Study 3 replicated the social influence effects observed in Study 2 and revealed the neural mechanisms contributing to this phenomenon. Additionally, this study used a broader range of stimuli including negative, neutral, and positive images, in order to expand the generalizability of the findings. Taken together this work uncovers neural, developmental, and social influences that shape how individuals experience emotions.

description: This dissertation investigates different statistical questions in the domain of semiconductor market forecasting and trend detection. The first investigation brings us into the realm of technological trend detection and technology life cycles. Common models to achieve these ends are technology diffusion models, such as the simple logistic growth model. Since this model represents a closed system view of a highly interconnected and complex phenomenon, we investigate the robustness of derived life cycle estimates with regard to an external shock, namely the COVID-19 pandemic, and its consequences on consumer demand and supply chains. While the logistic growth model takes a long-term perspective, we focus on the detection of shorter-term market dynamics with an investigation into forecasting the semiconductor market more broadly. A premier provider of semiconductor market data and industry forecasts is the World Semiconductor Trade Statistics (WSTS). As our second focus of attention, we investigate the precision of industry expert forecasts and explore if data-driven models can enhance such forecasts. Given that the WSTS product classification hierarchy has a degenerate structure, we proceed with an exploration of degenerate hierarchical forecast reconciliation to enable coherent forecasts. Lastly, we investigate the performance of a popular reconciliation algorithm, Trace Minimization (MinT), which was originally introduced by Wickramasuriya et al. (2019), in the context of very short time series through an elaborate simulation study and compare a proposed iterative alternative which requires far fewer parameters.

description: This dissertation reports on infrared optical spectroscopic studies of a novel class of materials named Dirac materials, which cover a broad range of materials including Topological Insulators (TI) and Dirac/Nodal-line semimetals. These materials share a similar low-energy Hamiltonian that can be described by massless/massive Dirac fermions. Adding out-of-plane magnetic field generates additional features in the optical spectra that allow us to distinguish Dirac fermions with usual fermions with parabolic bands. I will first demonstrate identifications of surface states (SS) of TI using Faraday rotation spectroscopy, where both the top and bottom SS can be identified and found to host carriers of opposite sign. Secondly, I will generalize the power-law behavior for two-dimensional (2D) and three-dimensional (3D) Dirac semimetals to dispersive nodal-line semimetals. This leads to the discoveries of Dirac nodal-lines in topological semimetal NbAs2. Finally, the optical signatures of electronic correlations are discussed and the unexplored overlapping area between strongly correlated systems and Dirac semimetals are studied. The prominent correlation effects in nodal-line semimetal ZrSiSe uncovered by a combination of optical and magneto-optical spectroscopies will be discussed.

description: In human pregnancy, recognition of an embryo within the uterus is essential to support the fetus through gestation. In non-macropodid marsupials, such as the opossums, pregnancy is shorter than the oestrous cycle and the steroid hormone profile during pregnancy and oestrous cycle are indistinguishable. For these reasons, it was assumed that recognition of pregnancy, as a trait, evolved in the eutherian (placental) stem lineage and independently in wallabies and kangaroos. To investigate whether uterine recognition of pregnancy occurs in species with pregnancy shorter than the oestrous cycle, we examined reproduction in the short-tailed opossum (Monodelphis domestica), a marsupial with a plesiomorphic mode of pregnancy. We examined the morphological and gene expression changes in the uterus of females in the non-pregnant oestrous cycle and compared these to pregnancy. We found that the presence of an embryo did not alter some aspects of uterine development but increased glandular activity. Transcriptionally, we saw big differences between the uterus of pregnant and cycling animals. These differences included an upregulation of genes involved in transport, inflammation and metabolic-activity in response to the presence of a fetus. Furthermore, transcriptional differences reflected protein level differences in transporter abundance. Our results suggest that while the uterus exhibits programmed changes after ovulation, its transcriptional landscape during pregnancy responds to the presence of a fetus and upregulates genes that may be essential for fetal support. These results are consistent with endometrial recognition of pregnancy occurring in the opossum. While the effects on maternal physiology appear to differ, recognition of pregnancy has now been observed in eutherian mammals, as well as, Australian and American marsupials.

description: This hilltop in East Sussex which overlooks the English Channel was occupied for much of the time between the beginning of the third millennium B.C. and the sixth century A.D. Neolithic occupation is represented by a series of pits, one of which contained an interesting group of flint tools, with associated environmental evidence. There is then a hiatus with only slight traces of occupation in the Bronze Age. During the early Iron Age a small farming settlement was established near the crest of the hill. Unenclosed in its primary phase, it was later surrounded by a rectangular enclosure, outside which were fields. Excavation showed that the latter were cultivated intermittently from the Neolithic to Romano-British periods. The Iron Age structures were mostly of the four and six-post types. Occupation continued throughout the Romano-British period in the early part of which a rectangular enclosure was laid out. The fifth century A.D. saw the establishment of an Anglo-Saxon settlement of rectangular buildings and sunken huts, which covered part of the earlier settlement and spread out over the former fields. On the edge of the settlement was a contemporary cemetery. Each period has produced evidence of the environment and economy. Studies of land and marine mollusc assemblages are included, and an attempt is made to classify pottery and clay objects on the basis of their contained minerals and to pinpoint possible clay sources.

description: This article reports on emergence of structures in a class of alternative theories of gravity. These theories do not have any horizon, flatness, initial cosmological singularity and (possibly) quantization problems. The model is characterised by a dynamically induced gravitational constant with a ``wrong'' sign corresponding to repulsive gravitation on the large scale. A non - minimal coupling of a scalar field in the model can give rise to non - topological solitons in the theory. This results in domains (gravity - balls) inside which an effective, canonical, attractive gravitational constant is induced. We consider simulations of the formation and evolution of such solutions. Starting with a single gravity - ball, we consider its fragmentation into smaller (lower mass) balls - evolving by mutual repulsion. After several runs, we have been able to identify two parameters: the strength of the long range gravitational constant and the size of the gravity balls, which can be used to generate appropriate two point correlations of the distribution of these balls.

Excursion set peaks in energy as a model for haloes

description: The simplest models of dark matter halo formation are based on the heuristic assumption, motivated by spherical collapse, that virialized haloes originate from initial regions that are maxima of the smoothed density field. Here, we replace this notion with the dynamical requirement that protohalo patches be regions where the local gravitational flow converges to a point. For this purpose, we look for spheres whose gravitational acceleration at the boundary -- relative to their center of mass -- points towards their geometric center: that is, spheres with null dipole moment. We show that these configurations are minima of the total energy, i.e. the most energetically bound spheres. For this reason, we study peaks of the energy overdensity field, and argue that the approach shows considerable promise. This change simply requires that one modify the standard top-hat filter, with the added important benefit that, for power spectra of cosmological interest, the resulting model is no longer plagued by divergences. Although the formalism is no more complicated than the overdensity based approach, the model is richer in the sense that it naturally predicts scatter in the overdensities of protohalo patches that are destined to form haloes of the same mass, in qualitative agreement with simulations of halo formation.

description: We discuss the generation of superpotentials in four-dimensional, N = 1 supersymmetric field theories arising from type IIA D6-branes wrapped on supersymmetric three-cycles of a Calabi-Yau threefold. In general, nontrivial superpotentials arise from sums over disc instantons. We find several examples of special Lagrangian three-cycles with nontrivial topology which are mirror to obstructed rational curves, conclusively demonstrating the existence of such instanton effects. In addition, we present explicit examples of disc instantons ending on the relevant three-cycles. Finally, we give a preliminary construction of a mirror map for the open string moduli, in a large-radius limit of the type IIA compactification.

description: We develop the general theory of Noether symmetries for constrained systems. In our derivation, the Dirac bracket structure with respect to the primary constraints appears naturally and plays an important role in the characterization of the conserved quantities associated to these Noether symmetries. The issue of projectability of these symmetries from tangent space to phase space is fully analyzed, and we give a geometrical interpretation of the projectability conditions in terms of a relation between the Noether conserved quantity in tangent space and the presymplectic form defined on it. We also examine the enlarged formalism that results from taking the Lagrange multipliers as new dynamical variables; we find the equation that characterizes the Noether symmetries in this formalism. The algebra of generators for Noether symmetries is discussed in both the Hamiltonian and Lagrangian formalisms. We find that a frequent source for the appearance of open algebras is the fact that the transformations of momenta in phase space and tangent space only coincide on shell. Our results apply with no distinction to rigid and gauge symmetries; for the latter case we give a general proof of existence of Noether gauge symmetries for theories with first and second class constraints that do not exhibit tertiary constraints in the stabilization algorithm. Among some examples that illustrate our results, we study the Noether gauge symmetries of the Abelian Chern-Simons theory in $2n+1$ dimensions. An interesting feature of this example is that its primary constraints can only be identified after the determination of the secondary constraint. The example is worked out retaining all the original set of variables.

description: Service Function Chaining (SFC) is the problem of deploying various network service instances over geographically distributed data centers and providing inter-connectivity among them. The goal is to enable the network traffic to flow smoothly through the underlying network, resulting in an optimal quality of experience to the end-users. Proper chaining of network functions leads to optimal utilization of distributed resources. This has been a de-facto model in the telecom industry with network functions deployed over underlying hardware. Though this model has served the telecom industry well so far, it has been adapted mostly to suit the static behavior of network services and service demands due to the deployment of the services directly over physical resources. This results in network ossification with larger delays to the end-users, especially with the data-centric model in which the computational resources are moving closer to end users. A novel networking paradigm, Network Function Virtualization (NFV), meets the user demands dynamically and reduces operational expenses (OpEx) and capital expenditures (CapEx), by implementing network functions in the software layer known as virtual network functions (VNFs). VNFs are then interconnected to form a complete end-to-end service, also known as service function chains (SFCs). In this work, we study the problem of deploying service function chains over network function virtualized architecture. Specifically, we study virtual network function placement problem for the optimal SFC formation across geographically distributed clouds. We set up the problem of minimizing inter-cloud traffic and response time in a multi-cloud scenario as an ILP optimization problem, along with important constraints such as total deployment costs and service level agreements (SLAs). We consider link delays and computational delays in our model.

Subjects: subject: 004

description: In radio interferometry, information about a small region of the sky is obtained in the form of samples in the Fourier transform domain of the desired image. Since this sampling is usually incomplete, the missing information has to be reconstructed using additional assumptions about the image. The emerging field of Compressed Sensing (CS) provides a promising new approach to this type of problem which is based on the supposed sparsity of natural images in some transform domain. We present a versatile CS-based image reconstruction framework called SparseRI, an interesting alternative to the clean algorithm, that permits a wide choice of different regularisers for interferometric image reconstruction. The performance of our method is evaluated on simulated data as well as on actual radio interferometry measurements from the VLA, showing that our algorithm is able to reproduce the main features of the test sources. The proposed method is a first step towards an alternative reconstruction approach that may be able to avoid typical artefacts like negative flux regions, work with large fields of view and non-coplanar baselines, avoid the gridding process, and reduce the amount of manual work that is required in order to obtain best-quality results.

description: We consider a differentially rotating flow of an incompressible electrically conducting and viscous fluid subject to an external axial magnetic field and to an azimuthal magnetic field that is allowed to be generated by a combination of an axial electric current external to the fluid and electrical currents in the fluid itself. In this setting we derive an extended version of the celebrated Hain-Lust differential equation for the radial Lagrangian displacement that incorporates the effects of the axial and azimuthal magnetic fields, differential rotation, viscosity, and electrical resistivity. We apply the Wentzel-Kramers-Brillouin method to the extended Hain-Lust equation and derive a new comprehensive dispersion relation for the local stability analysis of the flow to three-dimensional disturbances. We confirm that in the limit of low magnetic Prandtl numbers, in which the ratio of the viscosity to the magnetic diffusivity is vanishing, the rotating flows with radial distributions of the angular velocity beyond the Liu limit, become unstable subject to a wide variety of the azimuthal magnetic fields, and so is the Keplerian flow. In the analysis of the dispersion relation we find an evidence of a new long-wavelength instability which is caught also by the numerical solution of the boundary value problem for a magnetized Taylor-Couette flow.

description: We contrast the two approaches to ``classical" signature change used by Hayward with the one used by us (Hellaby and Dray). There is (as yet) no rigorous derivation of appropriate distributional field equations. Hayward's distributional approach is based on a postulated modified form of the field equations. We make an alternative postulate. We point out an important difference between two possible philosophies of signature change --- ours is strictly classical, while Hayward's Lagrangian approach adopts what amounts to an imaginary proper ``time" on one side of the signature change, as is explicitly done in quantum cosmology. We also explain why we chose to use the Darmois-Israel type junction conditions, rather than the Lichnerowicz type junction conditions favoured by Hayward. We show that the difference in results is entirely explained by the difference in philosophy (imaginary versus real Euclidean ``time"), and not by the difference in approach to junction conditions (Lichnerowicz with specific coordinates versus Darmois with general coordinates).

description: Prior to the decommissioning and reclamation of tailings impoundments it is critical to adequately characterize the geotechnical, hydrogeological, and geochemical nature of tailings. Important advances in the capability of in-situ testing for characterizing tailings impoundments have included the development of the resistivity piezocone and improved water sampling technologies. The standard piezocone is an excellent means of logging stratigraphy for most soils and also gives accurate estimates of key physical and hydrogeological parameters. The resistivity piezocone includes a geophysical module, which resides directly behind the standard piezocone during testing, which permits assessment of groundwater quality through the measurement of the bulk resistivity of the soil and the pore water. In addition, recently developed in-situ discrete groundwater sampling systems can be used to augment the bulk resistivity measurements and facilitate site-specific correlations with selected water quality parameters. This paper presents an overview of the resistivity piezocone and improved water sampling technologies and provides a summary of field testing programs carried out at large sulphide tailings impoundments at three Canadian mines. Test results are presented with respect to environmental and geotechnical aspects of sulphide tailings characterization.

description: We study generation of magnetic fields involving large spatial scales by time- and space-periodic small-scale parity-invariant flows. The anisotropic magnetic eddy diffusivity tensor is calculated by the standard procedure involving expansion of magnetic modes and their growth rates in power series in the scale ratio. Our simulations, conducted for flows with random harmonic composition and exponentially decaying energy spectra, demonstrate that enlargement of the spatial scale of magnetic field is beneficial for generation by time-periodic flows. However, they turn out, in general, to be less efficient dynamos, than steady flows.

description: Using properties of the determinant line bundle for a family of elliptic boundary value problems, we explain how the Fock space functor defines an axiomatic quantum field theory which formally models the Fermionic path integral. The 'sewing axiom' of the theory arises as an algebraic pasting law for the determinant of the Dirac operator. We show how representations of the boundary gauge group fit into this description and that this leads to a Fock functor description of certain gauge anomalies.

Inherently Flawed: Carbonation-Induced Cracking in Reinforced Concrete Structures

description: Concrete was considered an everlasting, permanent material from its expanding use at the end of the 19th century until the early 1900s. In the 1910s and 20s scientific research on concrete failure began, a response to the inevitable cracks and deterioration that began to plague concrete structures. Today cracks are recognized as an inevitable symptom of the deterioration of concrete structures. Early-age cracking is often due to improper rebar cover and carbonation-induced corrosion. This thesis explores some aspects of the cracking of reinforced concrete structures caused by carbonation-induced corrosion, and historical approaches to conservation repair and treatment, from the use of early cementitious patching and crack stitching in the 1950s to modern conservation materials, such as injectable crack fillers, sealers, and penetrating silane water repellents. This thesis has attempted to clarify the understanding of conservation treatments for reinforced concrete structures.
On asymptotic nonlocal symmetry of nonlinear Schrödinger equations
Creators: name: Zachary, Woodford W.
name: Shtelen, Vladimir M.
Publisher: name: arXiv
Year: 1998
Subjects: subject: Mathematical Physics (math-ph)
subject: FOS: Physical sciences

description: A concept of asymptotic symmetry is introduced which is based on a definition of symmetry as a reducibility property relative to a corresponding invariant ansatz. It is shown that the nonlocal Lorentz invariance of the free-particle Schrödinger equation, discovered by Fushchych and Segeda in 1977, can be extended to Galilei-invariant equations for free particles with arbitrary spin and, with our definition of asymptotic symmetry, to many nonlinear Schrödinger equations. An important class of solutions of the free Schrödinger equation with improved smoothing properties is obtained.
The alignment of Casamari Abbey along the moonrise azimuth on Easter 1203

Publisher: name: Zenodo
Year: 2019
Subjects: Archaeoastronomy

description: Casamari Abbey is a Cistercian abbey in Italy, about 10 kilometres from Veroli. The building of the church that we see today started in 1203. Here we show that a link can exist between the direction of the moonrise on Easter 1203 and that of the nave of the church. To determine the moonrise azimuth we use software CalSKY. To simulate it on satellite images, we use The Photographer’s Ephemeris.
Planary Symmetric Static Worlds with Massless Scalar Sources

subject: FOS: Physical sciences

description: Motivated by the recent wave of investigations on plane domain wall spacetimes with nontrivial topologies, the present paper deals with (probably) the most simple source field configuration which can generate a spatially planary symmetric static spacetime, namely a minimally coupled massless scalar field that depends only upon a spacelike coordinate, $z$. It is shown that the corresponding exact solutions $({\cal M}, {\bf{\rm g}}_{\pm})$ are algebraically special, type $D - [S - 3T]_{(11)}$, and represent globally pathologic spacetimes with a $G_{4}$ - group of motion acting on ${\bf{\rm R}}^{2} \times {\bf{\rm R}}$ orbits. In spite of the model simplicity, these $ϕ$ - generated worlds possess naked timelike singularities (reached within a finite universal time by normal non-spacelike geodesics), are completely free of Cauchy surfaces and contain into the $t$ - leveled sections points which can not be jointed by ${\rm C}^{1}$ - trajectories images of oblique non-spacelike geodesics. Finally, we comment on the possibility of deriving from $({\cal M}, {\bf{\rm g}}_{\pm})$ two other physically interesting ^^ ^^ $ϕ$ - generated'' spacetimes, by appropiate jonction conditions in the $(z = 0)$ - plane.

Bursts of extensive air showers: chaos vs. stochasticity

description: Bursts of the count rate of extensive air showers (EAS) lead to the appearance of clusters in time series that represent EAS arrival times. We apply methods of nonlinear time series analysis to twenty EAS cluster events found in the data set obtained with the EAS-1000 prototype array. In particular, we use the Grassberger-Procaccia algorithm to compute the correlation dimension of the time series in the vicinity of the clusters. We find that four cluster events produce signs of chaos in the corresponding time series. By applying a number of supplementary methods we assess that the nature of the observed behaviour of the correlation dimension is likely to be deterministic. We suggest a simple qualitative model that might explain an origin of clusters in general and "possibly chaotic" clusters in particular. Finally, we compare our conclusions with the results of similar investigations performed by the EAS-TOP and LAAS groups.
