description: We study the earth matter effects in the Tokai-to-Kamioka-and-Korea experiment (T2KK), which is a proposed extension of the T2K (Tokai-to-Kamioka) neutrino oscillation experiment between J-PARC at Tokai and Super-Kamiokande (SK) in Kamioka, where an additional detector is placed in Korea along the same neutrino beam line.By using recent geophysical measurements, we examine the earth matter effects on the oscillation probabilities at Kamioka and Korea. The average matter density along the Tokai-to-Kamioka baseline is found to be 2.6 g/cm^3, and that for the Tokai-to-Korea baseline is 2.85, 2.98, and 3.05 g/cm^3 for the baseline length of L = 1000, 1100, and 1200 km, respectively. The uncertainty of the average density is about 6%, which is determined by the uncertainty in the correlation between the accurately measured sound velocity and the matter density. The effect of the matter density distribution along the baseline is studied by using the step function approximation and the Fourier analysis. We find that the nu_mu -> nu_e oscillation probability is dictated mainly by the average matter density, with small but non-negligible contribution from the real part of the first Fourier mode. We also find that the sensitivity of the T2KK experiment on the neutrino mass hierarchy does not improve significantly by reducing the matter density error from 6% to 3%, since the measurement is limited by statistics for the minimum scenario of T2KK with SK at Kamioka anda 100 kt detector in Korea considered in this report. The sensitivity of the T2KK experiment on the neutrino mass hierarchy improves significantly by splitting the total beam time into neutrino and anti-neutrino runs, because the matter effect term contributes to the oscillation amplitudes with the opposite sign.

description: Given the observed poor performance of unreinforced concrete block masonry walls in recent earthquakes, there is significant demand in Canada and internationally for economical methods to improve the seismic performance of such walls. Common retrofit methods such as the application of external fibre reinforced polymer sheets, installation of conventional steel reinforcement or post-tensioning are often expensive, and visually intrusive. The proposed retrofit method involves filling the internal void space of concrete block walls with grout or a similar material that hardens after installation. This approach has been examined in a few studies, but has yet to be studied comprehensively. Herein referred to as core fill strengthening, this method has the potential to be a simple, unobtrusive and cost effective retrofit. In the current study, two core fill types, steel fibre reinforced grout and two part polyurethanes, have been examined. This was done through tests at a material level, tests of small masonry assemblages and tests on full scale masonry walls. These tests were coupled with finite element analyses of the various core fill materials, and later finite element models of full scale walls. Experimental results were then used to develop equations to predict the strength of core filled walls under in-plane shear failing in flexure, diagonal shear and sliding. Results indicate that core fill materials can improve both the strength and ductility of masonry walls in diagonal shear and flexure, and that further investigation into both polyurethane and steel fibre reinforced grout retrofits is justified.

description: Haemorrhage is a major challenge to the circulatory system and whole body homeostasis. Although the physiological responses to haemorrhage have been studied extensively in adults, there is still little known about those responses during the post-natal period. The goal of the present study was to investigate some of the cardiovascular and renal responses to severe haemorrhage during post-natal maturation. In addition, the present study aimed to elucidate the potential role of kappa opioid receptors in the cardiovascular and renal responses to severe haemorrhage. In order to achieve the goal of the study, two protocols were carried out in conscious lambs at two stages of post-natal maturation, one and six weeks. The first protocol investigated the cardiovascular effects of 30% haemorrhage and the associated changes in the arterial baroreflex control of heart rate. The second protocol investigated the effects of 30% haemorrhage on various parameters of renal function. Each protocol included a separate set of experiments to evaluate the role of endogenous activation of kappa opioid receptors after haemorrhage. Results from these experiments demonstrated for the first time the developmental variations in the cardiovascular and renal responses to severe haemorrhage. My results showed that the heart rate response to decompensatory haemorrhage is developmentally regulated in conscious lambs. In addition, my research results reveals underlying age-dependent variations in the arterial baroreflex control of heart rate after decompensatory haemorrhage. Also, my results indicated the importance of kappa opioid receptor activation in the decompensatory phase of response to haemorrhage and during the recovery phase early in life.
Characterization of the Lower Shoreface to Offshore Reservoir Facies of the Cardium Formation in East Pembina, Alberta

description: This thesis endeavors to define the reservoir characteristics, stratigraphy, facies architecture and their relationships of the Lower Cretaceous Cardium Formation in the northeast Pembina Oil Field of west-central Alberta. Bioturbated lower shoreface to offshore sandstones are subdivided into two separate depositional units. The lower depositional unit is characterized by four stacked shoreface-offshore parasequences (A – D), and the upper unit consists of two sandspit parasequences (E – F). The units are separated by an erosion surface that eroded the uppermost deposits of the underlying shoreface – offshore parasequence. Characterization of the low permeability Cardium reservoir facies indicates that the horizontal and vertical sand-filled burrows improve sandstone bed connectivity and enhance permeability flow pathways. Subsurface reservoir mapping coupled with facies characteristics and production data established a more thorough understanding of the reservoir characteristics and fairway widths of unconventional low permeability offshore deposits.

description: This research aims at integrating geochemical, petrophysical and geomechanical models of shale oil reservoirs built with data gathered from laboratory tests and well logs. The main objective is to identify intervals that contain free oil. The objective is achieved by developing new analytical models that permit interpreting the internal anatomy of the rock including its composition. The main challenge is that shale oil reservoirs are multi-porosity systems composed by natural fractures, inorganic matter and organic matter where the latter develops its own porosity. Results show a good agreement between free oil detected with the geochemical model and those zones with high total porosity and/or high natural fracture intensity. Although total organic carbon content in shale oil reservoirs is important, it is more meaningful to determine the volumes of free oil and how it is distributed in the shale pore space.

description: Similarly to the standard effective range expansion that is done near the threshold energy, we obtain a generalized power-series expansion of the multi-channel Jost-matrix that can be done near an arbitrary point on the Riemann surface of the energy within the domain of its analyticity. In order to do this, we analytically factorize its momentum dependencies at all the branching points on the Riemann surface. The remaining single-valued matrix functions of the energy are then expanded in the power-series near an arbitrary point in the domain of the complex energy plane where it is analytic. A systematic and accurate procedure has been developed for calculating the expansion coefficients. This means that near an arbitrary point in the domain of physically interesting complex energies it is possible to obtain a semi-analytic expression for the Jost-matrix (and therefore for the S-matrix) and use it, for example, to locate the spectral points (bound and resonant states) as the S-matrix poles.

Engaging Aboriginal Perspectives in the Alberta Social Studies Classroom: A Sociocultural Investigation Into Conceptual Possibilities and Teacher Beliefs

description: This doctoral thesis offers a sociocultural investigation into how one male Euro-Canadian social studies teacher interpreted and pedagogically responded to the curricular directive in Alberta to address Aboriginal perspectives, including the history of residential schools, treaties, and Aboriginal peoples’ historical and contemporary contributions to Canada. Employing case study methodology, the teacher’s practice was examined during a 10-2 social studies unit in which he was actively attempting to take up Aboriginal perspectives with his students. Data were collected from several channels including classroom observations, field journal notes, classroom documents, as well as ongoing semistructured interviews. Of note, the research participant avoided a number of resistances to engaging with Aboriginal perspectives that prior research had identified. Drawing on resources that honoured the voice of Indigenous peoples in ways that were not filtered through Euro-Canadian lenses, the teacher offered viable possibilities for engaging Aboriginal perspectives. Despite these positive developments, an overreliance on transmission-based pedagogies tied to the officially mandated textbook inhibited this teacher’s ability to sustain this work in his classroom. Further, a multicultural discourse where Aboriginal peoples are afforded opportunities to become benevolently integrated into the Canadian nation caused the research participant to significantly misrecognize the nature of Indigenous philosophies and hindered his ability to faithfully represent these perspectives to his students. Noting that these same tensions have been present in other studies, I argue that Canadian educators will be unable to engage with Aboriginal perspectives in qualitatively different ways without an alternative model or story to understand Aboriginal–Canadian relations. Drawing on insights from the work of Dwayne Donald, throughout the thesis I advance a number of relational possibilities for reconceptualizing Aboriginal–Canadian relations that draw inspiration from the Haudenosaunee Gus-Wen-Tah, or two-row wampum, as well as Cree understandings of the treaties. However, due to the First Nations–centric nature of these relational models, I ultimately argue that the purpose may not be to try to agree on one particular understanding of the relationship, but rather to place the nature of Aboriginal–Canadian relations at the centre of classroom deliberations.

description: The magnetic behavior of the quaternary compounds, RCr2Si2C (R = La, Ce), has been investigated by magnetization (M) and heat-capacity (C) measurements (1.8-300 K) in the bulk polycrystals and nano forms (<1 μm) obtained by high-energy balling. Our finding is that Cr appears to exhibit magnetic ordering of an itinerant type at low temperatures (<20 K) in the bulk form, as inferred from a combined look at all the data. The magnetic ordering gets gradually suppressed with increasing milling time. Evidence for a mixed-valence state of Ce for the bulk form is obtained from the tendency of magnetic susceptibility to exhibit a maximum above 300 K. However, this feature vanishes in the nano form, which exhibits a Curie-Weiss behavior above 200 K as though Ce tends towards trivalency in these fine particles; in addition, there is a weak upturn in C/T below 10 K in the bulk, which becomes very prominent in the milled Ce-based specimens at lower temperatures, as though heavy-fermion behavior gets stronger in smaller particles.
Modelling of Geomechanics for Informed Hydraulic Fracturing Operations

Subjects: Engineering--Petroleum

description: Multistages hydraulic fracturing of horizontal wells has been an integral part of natural Canadian resources, such as shales and tight gas reservoirs. In the hydraulic fracturing process, long horizontal well divided into several stages to access much larger volume of oil and gas in low permeability/porosity formations. Then the hydraulic fracture fluid is pumped into each stage to initiate and propagate the fractures around the well which increase the porosity and permeability of the formation. Although, the technology has greatly improved in the past decade to enhance the production from unconventional reservoirs, still several uncertainties can cause failure. Therefore, without geomechanical considerations, the predicted design of hydraulic fractures may not be completely accurate. Then understanding the reservoir rock mechanics and their spatial heterogeneity as well as stress profiles have a major impact on the reliable decisions in fracturing design optimization. In most simulation models, geomechanical properties are assumed to be homogeneous throughout the reservoir. In this study, the heterogeneity of geomechanical properties is demonstrated by using geomodeling. A three-dimensional (3D) earth model was built by integrating both petrophysical and geological log data using more than 200 wells in the study area. Then, the state-of-stress prior to hydraulic fracturing is estimated by using geological log data to create a geomechanical model from near surface to below the Montney FormationFormation. The model includes dynamic elastic properties and rock strength property distributions in both vertical and horizontal directions within the reservoir. To determine elastic rock properties, changes in compressional and shear velocity through all the layers of the reservoir rock were taken into consideration. A workflow was developed to constrain well properties to derive realistic rock property values and distributions even in areas where only limited well log information exist. Then Petrel/Visage software package used to evaluate stress changes within the Montney FormationFormation.Since this formation has very low permeability with complicated geological settings, the knowledge of geomechanical and geological properties, stresses magnitude and orientation, completion and production data is essential to evaluate the fracture volume and conductivity. In this research study, we presented an unconventional reservoir simulator and the critical parameter to quantify multistage hydraulic fracturing in the Montney Formations. Data from a detailed core analysis and various field logs are used to achieve a history match of initial production data from the liquids rich Montney well production within the study field.

description: Network management has become a tricky task in today's complex networks and distributed data centers. Software Defined Networking (SDN) provides more flexibility, eases automation, and gives a more comprehensive view of the network. In a software-defined network, traffic management functionality requires a high-performance and responsive controller. The SDN controller, as the “brain'' of the network, enables network administrators to classify, manipulate, and dynamically re-route an evolving set of traffic flows across many possible network paths. In mission-critical networks, having a flexible and carrier-grade controller is a high priority. In this thesis, we conduct an experimental evaluation of two open-source distributed OpenFlow controllers, namely ONOS and OpenDaylight. To this end, we construct a testbed and use a standard benchmarking tool called Cbench to evaluate their performance. We benchmark the throughput and latency of these controllers in both physical and virtual environments. The experimental results show that ONOS provides higher throughput and lower latency than OpenDaylight.

description: In the adult nervous system, white matter connecting brain, spinal, and peripheral regions is essential for neuron communication. In the white matter, the axon plays an essential role in transmitting nerve impulses, while myelin facilitates conduction through rapid propagation and optimal energy-consumption. White matter injury in the central nervous system, leading to the degeneration of axons and myelin, is commonly found in multiple sclerosis, anoxia, ischemic stroke, and traumatic brain and spinal cord injury. These lead to cognitive impairment, sensorimotor disability or death. During white matter injury, axonal spheroid formation (ASF) and demyelination are the pathological hallmarks of white matter degeneration. However, the mechanism by which this occurs is unknown. I hypothesize that focal spheroids are induced by activation of glutamate receptors and lead to local calcium overload in axons. To test this hypothesis, I established an ex vivo imaging model of central white matter dorsal column using two-photon microscopy to investigate this phenomenon. Ex vivo imaging of the white matter dorsal column with high-spatial resolution was achieved, which allowed the observation of morphology of axon and myelin before and during injury. The dynamic imaging of live myelinated axon response to injury suggests that axons and myelin are not as passive as previously thought. The data presented in this thesis support the notion of over-activation of glutamate receptors inducing ASF and a calcium rise leading to axonal transection. In addition, I established a novel method using solvatochromic dyes to investigate the biochemical property of myelin in which changes in the lipid composition served as a health indicator of myelin. The study of live myelin with solvatochromic dyes to stain myelin lipids could report different stages ranging from development, maturity, injury, and repair of myelin.

description: The sum degrees of freedom (DoF) of the two-user MIMO X-channel is characterized in the presence of output feedback and delayed channel state information (CSI). The number of antennas at each transmitters is assumed to be M and the number of antennas at each of the receivers is assumed to be N. It is shown that the sum DoF of the two-user MIMO X-channel is the same as the sum DoF of a two-user MIMO broadcast channel with 2M transmit antennas, and N antennas at each receiver. Hence, for this symmetric antenna configuration, there is no performance loss in the sum degrees of freedom due to the distributed nature of the transmitters. This result highlights the usefulness of feedback and delayed CSI for the MIMO X-channel. The K-user X-channel with single antenna at each transmitter and each receiver is also studied. In this network, each transmitter has a message intended for each receiver. For this network, it is shown that the sum DoF with partial output feedback alone is at least 2K/(K+1). This lower bound is strictly better than the best lower bound known for the case of delayed CSI assumption for all values of K.

Optimal estimation of the mean function based on discretely sampled functional data: Phase transition

description: The problem of estimating the mean of random functions based on discretely sampled data arises naturally in functional data analysis. In this paper, we study optimal estimation of the mean function under both common and independent designs. Minimax rates of convergence are established and easily implementable rate-optimal estimators are introduced. The analysis reveals interesting and different phase transition phenomena in the two cases. Under the common design, the sampling frequency solely determines the optimal rate of convergence when it is relatively small and the sampling frequency has no effect on the optimal rate when it is large. On the other hand, under the independent design, the optimal rate of convergence is determined jointly by the sampling frequency and the number of curves when the sampling frequency is relatively small. When it is large, the sampling frequency has no effect on the optimal rate. Another interesting contrast between the two settings is that smoothing is necessary under the independent design, while, somewhat surprisingly, it is not essential under the common design.

description: Embryonic stem cells (ESCs) are capable of self-renewal and differentiation into any cell type; this is a powerful tool in generating different cell lineages for regenerative medicine. Stirred suspension bioreactors have been developed as a way to culture ESCs quickly and with minimal labour. Cells are stirred at 100 RPM, which has a maximum tip shear stress of 6 dyne/cm2. We have discovered that cells grown under these conditions maintain pluripotency even in the absence of leukemia inhibitory factor (LIF), an obligate pluripotency maintenance factor. Prior studies have shown that cells can sense physical signals such as shear stress in their environment and modulate a biochemical response through mechanotransduction. In this thesis, I show a link between mechanotransduction and the maintenance of pluripotency. In response to shear stress, β-catenin, a member of the wnt pathway is translocated to the nucleus. Inhibition of β-catenin in the bioreactor results in a decrease in pluripotency gene expression. The disruption of vinculin, a protein recruited to the periphery of the cell in response to shear stress, also leads to a reduction in bioreactor induced pluripotency. Direct manipulation of cells bound to Ecadherin peptides with shear stress generates nuclear β-catenin translocation as well as accumulation of vinculin on the periphery of the cell. These results indicate that shear stress induces bioreactor maintained pluripotency, a phenomenon we have named mechanopluripotency.

description: We study the non equilibrium statistical properties of a one dimensional hard-rod fluid undergoing collisions and subject to a spatially non uniform Gaussian heat-bath and periodic potential. The system is able to sustain finite currents when the spatially inhomogeneous heat-bath and the periodic potential profile display an appropriate relative phase shift, $ϕ$. By comparison with the collisionless limit, we determine the conditions for the most efficient transport among inelastic, elastic and non interacting rods. We show that the situation is complex as, depending on shape of the temperature profile, the current of one system may outperform the others.

The contributions of Cav2.1 alternative splicing and calcium-dependent modulation to congenital migraine
Creators: name: Adams, Paul Jacob
Publisher: name: University of British Columbia
Year: 2010

description: Cav2.1 calcium (Ca²⁺) channels are expressed throughout the mammalian central nervous system where they mediate P/Q-type Ca²⁺ currents essential for neurotransmitter release at most fast synapses. In humans, naturally occurring mutations in the CACNA1A gene encoding Cav2.1 are associated with several severe congenital disorders including familial hemiplegic migraine type 1 (FHM-1). Alternative splicing of the Cav2.1 transcript generates multiple functionally distinct channel variants with unique spatial and temporal expression patterns. Yet, whether different Cav2.1 splice variants have distinct responses to FHM-1 missense mutations that relate to the localized, episodic nature of the FHM-1 phenotype has not been explored. Using recombinant Cav2.1 channels, we systematically compared the biophysical effects of three FHM-1 mutations in two prevalent Cav2.1 splice variants. All three FHM-1 mutations caused differential effects on voltage-dependent and kinetic properties when expressed in the short carboxyl terminus variant (Cav2.1 Δ47) compared to the long variant (Cav2.1 +47). Our findings provide important insight concerning the role of Cav2.1 alternative splicing and the pathophysiology of FHM-1. Ca²⁺-dependent facilitation (CDF) of Cav2.1 channels is a powerful means of channel control proposed to play a role in short-term facilitation of synaptic release during repetitive action potentials (APs). However, empirical evidence to support CDF of Cav2.1 as a relevant mechanism of synaptic facilitation in the CNS is limited. As such, short-term facilitation of synaptic release is generally attributed to enhanced vesicle release due to residual Ca²⁺ binding to sensor proteins that directly mediate vesicle fusion and transmitter release. However, we found that two FHM-1 mutations occluded CDF of Cav2.1 in both recombinant and native systems and cause a corresponding attenuation in short-term synaptic facilitation at the cerebellar parallel fibre to Purkinje synapse. This is the first evidence that presynaptic Ca²⁺ at this fast central synapse also enhances Ca²⁺ influx through Cav2.1 by means of CDF and acts as an additional required mechanism for short-term plasticity. Thus, the data supports the notion that CDF of Cav2.1 underlies key aspects of short-term plasticity in the CNS and provides the first evidence that FHM-1 mutations directly affect Cav2.1 CDF.

description: We look at the generalisation of topologically massive gravity (TMG) to higher spins, specifically spin-3. We find a special "chiral" point for the spin-three, analogous to the spin-two example, which actually coincides with the usual spin-two chiral point. But in contrast to usual TMG, there is the presence of a non-trivial trace and its logarithmic partner at the chiral point. The trace modes carry energy opposite in sign to the traceless modes. The logarithmic partner of the traceless mode carries negative energy indicating an instability at the chiral point. We make several comments on the asymptotic symmetry and its possible deformations at this chiral point and speculate on the higher spin generalisation of LCFT2 dual to the spin-3 massive gravity at the chiral point.

description: The Ice Seasons is a 25-minute composition that evokes the beauty and behaviour of sub-Arctic ice found on lakes around Yellowknife, Northwest Territo- ries. The composition contains material drawn from reading scientific literature, an- alyzing field recordings, and thinking deeply about personal experiences of lake ice. The instrumentation is SSAATB choir with a soprano soloist, string sextet (2 violins, 2 violas, 2 cellos), and recorded sound files. I derive pitch material from an- alyzing field recordings of ice sounds using spectral analysis, and building the re- sults into six-note symmetrical harmonies; I connect rhythmic activity to elemental rhythms in the ice by using controlled-aleatory and sound-mass textures; and, I set poems and texts that describe different states of the ice. The thesis comprises an introductory essay that describes the form, the pitch, rhythmic, textural, and sound file material, and includes an appendix with the complete performance score.

Relying on the moving body as the primary means of communication, I explore the theme of friendship, through an interpersonal relationship, as shaped by the nuance of expressive human movement.

description: Recently, we reported an anomalous enhancement of the positive magnetoresistance beyond a critical magnetic field in Tb5Si3 in the magnetically ordered state, attributable to 'inverse metamagnetism'. This results in unusual magnetic hysteresis loops for the pressurized specimens, which are relevant to the topic of 'electronic phase separation'. In this paper, we report the influence of small substitutions of Lu for Tb, to show the evolution of these magnetic anomalies. We find that, at low temperatures, the high-field high-resistivity phase could be partially stabilized on returning the magnetic field to zero in many of these Lu substituted alloys, as measured through the electrical resistivity (ρ). Also, the relative fractions of this phase and the virgin phase appear to be controlled by a small tuning of the composition and temperature. Interestingly, at 1.8 K a sudden 'switch-over' of the value of ρ for this mixed phase to that for the virgin phase for some compositions is observed at low fields after a few field cycles, indicating metastability of this mixed phase.

description: We study magnetic fluctuations in a system of interacting spins on a lattice at high temperatures and in the presence of a spatially varying magnetic field. Starting from a microscopic Hamiltonian we derive effective equations of motion for the spins and solve these equations self-consistently. We find that the spin fluctuations can be described by an effective diffusion equation with a diffusion coefficient which strongly depends on the ratio of the magnetic field gradient to the strength of spin-spin interactions. We also extend our studies to account for external noise and find that the relaxation times and the diffusion coefficient are mutually dependent.

description: We report an investigation of the lattice dynamical properties in a range of Fe$_{1+y}$Te$_{1-x}$Se$_{x}$ compounds, with special emphasis on the c-axis polarized vibration of Fe with B$_{1g}$ symmetry, a Raman active mode common to all families of Fe-based superconductors. We have carried out a systematic study of the temperature dependence of this phonon mode as a function of Se $x$ and excess Fe $y$ concentrations. In parent compound Fe$_{1+y}$Te, we observe an unconventional broadening of the phonon between room temperature and magnetic ordering temperature $T_N$. The situation smoothly evolves towards a regular anharmonic behavior as Te is substituted for Se and long range magnetic order is replaced by superconductivity. Irrespective to Se contents, excess Fe is shown to provide an additional damping channel for the B$_{1g}$ phonon at low temperatures. We performed Density Functional Theory (DFT) ab-initio calculations within the local density approximation (LDA) to calcuate the phonon frequencies including magnetic polarization and Fe non-stoichiometry in the Virtual Crystal Approximation (VCA). We obtained a good agreement with the measured phonon frequencies in the Fe-deficient samples, while the effects of Fe excess are poorly reproduced. This may be due to excess Fe-induced local magnetism and low energy magnetic fluctuations that can not be treated accurately within these approaches. As recently revealed by neutron scattering and $μ$-SR studies, these phenomena occur in the temperature range where anomalous decay of the B$_{1g}$ phonon is observed, and suggests a peculiar coupling of this mode with local moments and spin fluctuations in Fe$_{1+y}$Te$_{1-x}$Se$_{x}$.

description: In the Expanding Solvent-Steam Assisted Gravity Drainage (ES-SAGD), the mass transfer of dissolved solvent in mobile oil zone is critical to oil production performance. The mechanism of the solvent mass transfer, however, still remains unclear. Experimental and numerical simulation approaches are used to investigate the transverse movement at the steam chamber edge in ES-SAGD. The findings confirm that the transverse movement by gravity-driven convection exists in the interfacial flow both in the experiment and reservoir-scale simulation model, which is in contrast with previous studies. Experimental results show that the transverse movement of solvent increases with higher permeability and decreases with higher flow rate and higher viscosity. Diffusion has a small effect on the solvent mass transfer process and oil recovery factor. Fine grid block size is essential for reservoir-scale simulations of ES-SAGD to capture the convective flow of solvent at the steam chamber edge.

description: Many images nowadays are captured from behind the glasses and may have certain stains discrepancy because of glass and must be processed to make differentiation between the glass and objects behind it. This research paper proposes an algorithm to remove the damaged or corrupted part of the image and make it consistent with other part of the image and to segment objects behind the glass. The damaged part is removed using total variation inpainting method and segmentation is done using kmeans clustering, anisotropic diffusion and watershed transformation. The final output is obtained by interpolation. This algorithm can be useful to applications in which some part of the images are corrupted due to data transmission or needs to segment objects from an image for further processing.

Towards Review Spam Detection

description: Nowadays, millions of products and services are available to the public online. Therefore, searching for the best products which targets the individuals’ requirements would be difficult as the result of the existence of too many offers. One of the most reliable approaches to choose a product or service is to exploit the experiences of the people who have already tried them, and so have reported almost honest opinions about them. A reviewing system is a place where individuals write their reviews on their experienced products and services, and also benefit from others’ reviews. Moreover, companies utilize reviewing systems to apply opinion mining techniques in order to improve their goods or services and to watch their competitors. However, the popularity of the reviewing systems ignites this motivation for some people to enter their fake review to promote some products or defame some others. These review spam should get detected and eliminated in order to prevent misleading potential customers. Opinion mining should be adapted to locate and eliminate potential spam reviews. In this thesis, some review spam detection approaches have been proposed and examined over a sample dataset. The proposed approaches consider the patterns existed in the trends of the reviews, as well as the reviewers’ behaviors. The approaches depend on various strategies such as observing abnormal trends, detecting uncommon or suspicious behaviors, investigating group activities, and so on.
