Annular displacement flows with rotating inner pipe
Creators: name: Sotoudeh, Fatemeh (Sophia)
Publisher: name: University of British Columbia
Year: 2024

description: This thesis investigates the fluid mechanics of displacement flows in eccentric horizontal and inclined annuli, focusing on applications in well cementing operations in the oil and gas industry. These annular geometries, particularly eccentric ones, pose challenges during fluid displacement, leading to residual mud channels that can compromise well integrity. Understanding the interactions between eccentricity, fluid properties, flow rates, and casing rotation is essential to improving displacement efficiency and cementing reliability. Key parameters studied include fluid viscosity, density contrasts, eccentricity, annular inclination, and casing rotation. In highly eccentric annuli, the casing settles at the bottom, creating a narrow gap where residual mud can remain trapped. Casing rotation is explored as a solution, inducing helical fluid movement that helps lift the residual mud and improve displacement. However, rotation also introduces flow instabilities and local mixing, complicating the flow dynamics. 3D Computational Fluid Dynamics (CFD) simulations are conducted to analyze velocity and concentration profiles, offering insights difficult to capture experimentally. These simulations are validated against experimental data for accuracy. Results show that higher casing rotational speeds significantly enhance displacement efficiency by promoting azimuthal dispersion and reducing mud channel formation. Rotation induces secondary flows, leading to more uniform displacement. Interestingly, instabilities on the inner annulus wall were observed, a phenomenon not noted in previous experiments, with potential implications for cementing designs. The study also examines the nonlinear effects of buoyancy, viscosity, and eccentricity on displacement efficiency, visualized through contour plots. While higher rotational speeds generally improve displacement, they also increase the risk of localized mixing and flow instabilities, requiring careful management. In conclusion, this research enhances the understanding of displacement flows in eccentric annuli, highlighting the benefits and risks of casing rotation. The findings offer practical strategies for optimizing cementing processes, contributing to well integrity and performance in the oil and gas industry.

description: The distillable entanglement of a bipartite quantum state does not exceed its entanglement cost. This well known inequality can be understood as a second law of entanglement dynamics in the asymptotic regime of entanglement manipulation, excluding the possibility of perpetual entanglement extraction machines that generate boundless entanglement from a finite reserve. In this paper, I establish a refined second law of entanglement dynamics that holds for the non-asymptotic regime of entanglement manipulation.

description: Recently it was shown that an inflationary background can be realized by any $p$-form field non-minimally coupled to gravity. In this paper, we study gravitational waves generated during p-form inflation. Even though the background evolution is identical to that in conventional scalar field inflation, the behavior of gravitational waves is different in p-form inflation. In particular, we find that the propagation speed of gravitational waves differs from unity in 2- and 3-form inflationary models. We point out that the squared speed becomes negative in the large field models. The small field models are free from pathologies and the correction to the spectrum of gravitational waves turns out to be very small.

Synchronization of discrete-time dynamical networks with time-varying couplings

description: We study the local complete synchronization of discrete-time dynamical networks with time-varying couplings. Our conditions for the temporal variation of the couplings are rather general and include both variations in the network structure and in the reaction dynamics; the reactions could, for example, be driven by a random dynamical system. A basic tool is the concept of Hajnal diameter which we extend to infinite Jacobian matrix sequences. The Hajnal diameter can be used to verify synchronization and we show that it is equivalent to other quantities which have been extended to time-varying cases, such as the projection radius, projection Lyapunov exponents, and transverse Lyapunov exponents. Furthermore, these results are used to investigate the synchronization problem in coupled map networks with time-varying topologies and possibly directed and weighted edges. In this case, the Hajnal diameter of the infinite coupling matrices can be used to measure the synchronizability of the network process. As we show, the network is capable of synchronizing some chaotic map if and only if there exists an integer T>0 such that for any time interval of length T, there exists a vertex which can access other vertices by directed paths in that time interval.
Sachdev-Ye-Kitaev type physics in the strained Kitaev honeycomb model
Creators: name: Fremling, Mikael
name: Fritz, Lars
Publisher: name: arXiv
Year: 2021
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: In this work, we investigate whether the Kitaev honeycomb model can serve as a starting point to realize the intriguing physics of the Sachdev-Ye-Kitaev (SYK) model. The starting point is to strain the system, which leads to flat bands reminiscent of Landau levels, thereby quenching the kinetic energy. The presence of weak residual perturbations, such as Heisenberg interactions and the $γ$-term, creates effective interactions between the Majorana modes when projected into the flux-free sector. We assume the resulting interactions to be effectively random. This leads to a bipartite Sachdev-Ye-Kitaev model (b-SYK) with very similar properties as the SYK model. We also hypothesize under which conditions one would expect the standard SYK model in such a setup.

A study of sporadic pulsars and radio transients with the CHIME telescope

description: The Canadian Hydrogen Mapping Experiment (CHIME) is a radio telescope located in British Columbia, Canada. Initially built to survey the neutral hydrogen in the universe, it has had multiple additional jobs thrust upon its shoulders. One such responsibility is the discovery and continual monitoring of pulsars. With the large sky coverage and daily observing cadence, CHIME lends itself well to the hitherto poorly understood population of sporadic pulsars. The understanding of the population of sporadic pulsars, and in turn, all pulsars, will be informative for many areas of Galactic archaeology and supernova. First, I develop a new way to correct for the selection effects in the brightness distribution and nulling fraction of pulsars using their single pulses. This method, called LuNfit, is unique in that it can be applied to the most extreme examples of sporadic pulsars. Furthermore, it can be used on radio transients that do not have underlying periods, such as repeating fast radio bursts. I demonstrate the effectiveness of LuNfit by applying it to three known rotating radio transients (RRATs). I show that despite being classified as a RRAT through null detections when folding, PSR J0012+54 is may be a persistent emitter. Then, I take LuNfit further and incorporate pulse widths into the process. I conduct a year-long single pulse survey with CHIME/FRB, detecting 424 known and unknown pulsars. I apply LuNfit to a subset of 35 pulsars. This effort lays the groundwork for a larger population level analysis using large field of view single pulse surveys like CHIME/FRB. Finally, I discover a new long period transient, CHIME J0630+25, with a period of 421 s. This marks the fifth object in this new class. Their nature remains unknown, but I speculate that CHIME J0630+25 is likely a white dwarf or a neutron star. I further monitor the object across multiple wavelengths. With Neils Gehrels Swift X-ray telescope observations, I find 2 potential X-ray counterparts. At a distance of 170 pc, CHIME J0630+25 is the closest known long period transient.

description: We study the entanglement dynamics in a two-spin system governed by a bilinear Hamiltonian and assisted by phase kicks. It is found that the application of instant kicks to both spins at some specific moments leads to enhancement of entanglement. This procedure also improves the transient character of entanglement leading, for large spins, to a formation of a plateau for the I-concurrence. We have numerically investigated the spin-spin dynamics for several values of spins and observed a substantial enhancement of entanglement in comparison to the evolution without kicks.

Energy stability of plane Couette and Poiseuille flows and Couette paradox

description: We study the nonlinear stability of plane Couette and Poiseuille flows with the Lyapunov second method by using the classical L2-energy. We prove that the streamwise perturbations are L2-energy stable for any Reynolds number. This contradicts the results of Joseph [10], Joseph and Carmi [12] and Busse [4], and allows us to prove that the critical nonlinear Reynolds numbers are obtained along two-dimensional perturbations, the spanwise perturbations, as Orr [16] had supposed. This conclusion combined with recent results by Falsaperla et al. [8] on the stability with respect to tilted rolls, provides a possible solution to the Couette-Sommerfeld paradox.

Affective environments : nature-culture in narratives about the Pampas and Patagonia (19th-21st centuries)
Creators: name: Robles, Patricio
Publisher: name: University of British Columbia
Year: 2024

description: This dissertation engages with narratives set in the Southern Cone of the Americas: the Pampas and Patagonia. I focus on two periods—the late nineteenth to early twentieth centuries and the late twentieth to early twenty-first centuries—during which there has been considerable writing. This dissertation centers on one aspect: the relationship between nature and culture, a dualism that, I argue, becomes a regional trope. In the early chapters, I examine how both regions were characterized by European travellers and Argentine writers, analyzing foundational figures such as Domingo Faustino Sarmiento, Charles Darwin, and Francisco Moreno. They described these geographies as spaces dominated by untamed nature, sometimes as deserts that impose adverse conditions for establishing society. With nuances, they promoted the taming of these regions to develop the Argentine nation. In a word, they fostered the drive for modernity. In this first period, I also analyze narratives from the gauchesca genre. They reflect a questioning of the postulates of modernity, but I state they still operate within the foundational parameters. They reveal, though, that when there is a critique of modernity, the narratives tend to emphasize the other aspect of dualism, in this case, nature. Following this assertion, my central observation is that the dichotomy tends to be subverted in contemporary narratives following an extensive questioning of modernity. In the last two chapters, I examine travel writing in Patagonia by authors such as Bruce Chatwin, Luis Sepúlveda, Mempo Giardinelli, and Maristella Svampa, and novels of the “rural turn” in the Pampas by authors like Matilde Sánchez, Natalia Rodríguez, and Samanta Schweblin. Although I state that there is a reversal of the dualism, the perceptions of both regions differ, due to what I call space occupation and affective intensities. Different levels of intervention in both regions influence the narratives’ portrayal. During the twentieth century, the Pampas became Argentina's main productive area, while Patagonia remained largely unaltered. Analyzing these divergent trajectories, I study how representations evolved differently. In Patagonia, narratives tend to depict a space that requires protection. Meanwhile, in the Pampas, they lean toward portraying a space completely altered by human intervention.
Proficient Pair of Replacement Algorithms on L1 and L2 Cache for Merge Sort

description: Memory hierarchy is used to compete the processors speed. Cache memory is the fast memory which is used to conduit the speed difference of memory and processor. The access patterns of Level 1 cache (L1) and Level 2 cache (L2) are different, when CPU not gets the desired data in L1 then it accesses L2. Thus the replacement algorithm which works efficiently on L1 may not be as efficient on L2. Similarly various applications such as Matrix Multiplication, Web, Fast Fourier Transform (FFT) etc will have varying access pattern. Thus same replacement algorithm for all types of application may not be efficient. This paper works for getting an efficient pair of replacement algorithm on L1 and L2 for the algorithm Merge Sort. With the memory reference string of Merge Sort, we have analyzed the behavior of various existing replacement algorithms on L1. The existing replacement algorithms which are taken into consideration are: Least Recently Used (LRU), Least Frequently Used (LFU) and First In First Out (FIFO). After Analyzing the memory reference pattern of Merge Sort, we have proposed a Partition Based Replacement algorithm (PBR_L1)) on L1 Cache. Furthermore we have analyzed various pairs of algorithms on L1 and L2 respectively, resulting in finding a suitable pair of replacement algorithms. Simulation on L1 shows, among the considered existing replacement algorithms FIFO is performing better than others. While the proposed replacement algorithm PBR_L1 is working about 1.7% to 44 % better than FIFO for various cache sizes.

description: We report experimental observations and numerical simulations of the formation, dynamics, and lifetimes of single and multiply charged quantized vortex dipoles in highly oblate dilute-gas Bose-Einstein condensates (BECs). We nucleate pairs of vortices of opposite charge (vortex dipoles) by forcing superfluid flow around a repulsive gaussian obstacle within the BEC. By controlling the flow velocity we determine the critical velocity for the nucleation of a single vortex dipole, with excellent agreement between experimental and numerical results. We present measurements of vortex dipole dynamics, finding that the vortex cores of opposite charge can exist for many seconds and that annihilation is inhibited in our highly oblate trap geometry. For sufficiently rapid flow velocities we find that clusters of like-charge vortices aggregate into long-lived dipolar flow structures.

The extremely collimated bipolar H_2O jet from the NGC 1333-IRAS 4B protostar

description: We have performed observations of water maser emission towards a sample of low-mass protostars, in order to investigate the properties of jets associated with the earliest stages of star formation and their interaction with the surrounding medium. The main aim is to measure the absolute positions and proper motions of the H_2O spots in order to investigate the kinematics of the region from where the jet is launched. We imaged the protostars in the nearby region NGC 1333-IRAS 4 in the water maser line at 22.2 GHz by using the VLBA in phase-reference mode at the milliarcsecond scale over four epochs, spaced by one month to measure proper motions. Two protostars (A2 and B) were detected in a highly variable H_2O maser emission, with an active phase shorter than four weeks. The H_2O maps allow us to trace the fast jet driven by the B protostar: we observed both the red- and blue-shifted lobes very close to the protostar, =< 35 AU, moving away with projected velocities of ~10-50 km/s. The comparison with the molecular outflow observed at larger scale suggests a jet precession with a 18'/yr rate. By measuring the positional spread of the H_2O spots we estimate a jet width of ~2 AU at a distance of ~12 AU from the driving protostar.

description: The dissertation offers a novel theoretical framework for the investigation of cognitive poetics in cinema. Drawing from cognitive linguistic tools and concepts, the project offers film analysts a methodology for analyzing the conceptual structure of cinematic expression and narrative discourse. To expose the unique conceptual structure of cinematic expression and more rigorously define the properties of conceptual and narrative meaning in cinema, I examine cinematic artifacts that use cinematic techniques, such as cinematography and editing, to convey viewpoint, narrative distortions, and character affective experience. The project begins with the observation that language is a product of cognition, and with that understanding we can apply cognitive linguistic theories to multimodal film analysis. Moreover, analyzing the conceptual structure of cinematic representation can show how we understand meaning in dynamic and multimodal narratives. Taking the conceptual structure of cinematic expression as the starting point of my assessment, I suggest that a cognitive poetics approach can reveal the paths of conceptualization in dynamic and multimodal artforms. Developing on recent cognitive linguistic examinations of film, I further demonstrate that by analyzing the conceptual structure of cinematic expression we can see how multimodal affordances evoke perceptual, narrative, and affective meaning. I then offer a method for analyzing complex representations of character experience, especially in films that depict experiences that no one has ever had. I draw upon theories of embodied cognition and film analysis to develop a framework for understanding cinematic viewpoint networks, narrative spaces, and embodied affective cues in cinema. These three major contributions serve as a guiding framework for the analysis of character’s subjective experience. Thus, the majority of examples used through the dissertation look at depictions of characters’ subjective states. Ultimately, the project contributes to the fields of cognitive poetics, cognitive linguistics, cognitive film analysis, and multimodal discourse analysis by demonstrating the various ways in which conceptual structure can emerge to inform our knowledge of a film.

description: Following anterior cruciate ligament (ACL) reconstruction, patients commonly undergo prolonged rehabilitation (e.g., 9-12 months), but only a small proportion of individuals actually return to pre-injury sports activities. Therefore, research is needed to evaluate the nature and contribution of different components of rehabilitation programs. The purpose of this scoping review is to understand the variety of exercise prescriptions in rehabilitation programs that improve musculoskeletal, biomechanical, functional, or patient-reported outcome measures in athletes with ACL reconstruction. In this review, articles will be selected from searches in PubMed, EbscoHost (MEDLINE, SportDiscus, CINAHL Plus), PROQuest, Cochrane, and Embase. Studies will be included if they evaluated a post-ACL reconstruction rehabilitation program including strength, balance, plyometric, change of direction running, agility running, and self-reported physical function, quality of life, or pain. Data will be used to evaluate the reporting acute program variables (APVs), exercise descriptors (EDs) and outcomes for the various rehabilitation programs observed in selected studies.
