So, in this paper, the recovery of oil by the waterflooding technique from petroleum reservoir are considered. To investigate the aforementioned phenomena, the relative permeability of two immiscible fluids in sand is measured in the laboratory based on the steady-state method. Two sorts of oils, kerosene and heavy oil, and water are pumped simultaneously into a vertical sand column with different pumping ratio. From the change in fractional discharge measured at the outlet, a method for determining the relative permeability is developed focusing on the displacement mechanism in sand. Then, displacement mechanism of two immiscible fluids in the sand is investigated under the Buckley-Leveret frontal displacement theory and laboratory experiment. Two sorts of experiments, one is the displacement of pore water by oil, the other is the displacement of pore oil by water, are carried out. It is revealed that the relative permeability curves display tolerably different shape owing to the properties of oils, and produce different amount of residual oils and irreducible water saturation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=petroleum%20reservoir%20engineering" title="petroleum reservoir engineering">petroleum reservoir engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=relative%20permeability" title=" relative permeability"> relative permeability</a>, <a href="https://publications.waset.org/abstracts/search?q=two-phase%20flow" title=" two-phase flow"> two-phase flow</a>, <a href="https://publications.waset.org/abstracts/search?q=immiscible%20displacement%20in%20porous%20media" title=" immiscible displacement in porous media"> immiscible displacement in porous media</a>, <a href="https://publications.waset.org/abstracts/search?q=steady-state%20method" title=" steady-state method"> steady-state method</a>, <a href="https://publications.waset.org/abstracts/search?q=waterflooding" title=" waterflooding"> waterflooding</a> </p> <a href="https://publications.waset.org/abstracts/59676/experimental-and-graphical-investigation-on-oil-recovery-by-buckley-leveret-theory" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59676.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">247</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1006</span> Two-Dimensional Observation of Oil Displacement by Water in a Petroleum Reservoir through Numerical Simulation and Application to a Petroleum Reservoir</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Fahim%20Nasiry">Ahmad Fahim Nasiry</a>, <a href="https://publications.waset.org/abstracts/search?q=Shigeo%20Honma"> Shigeo Honma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We examine two-dimensional oil displacement by water in a petroleum reservoir. The pore fluid is immiscible, and the porous media is homogenous and isotropic in the horizontal direction. Buckley-Leverett theory and a combination of Laplacian and Darcy’s law are used to study the fluid flow through porous media, and the Laplacian that defines the dispersion and diffusion of fluid in the sand using heavy oil is discussed. The reservoir is homogenous in the horizontal direction, as expressed by the partial differential equation. Two main factors which are observed are the water saturation and pressure distribution in the reservoir, and they are evaluated for predicting oil recovery in two dimensions by a physical and mathematical simulation model. We review the numerical simulation that solves difficult partial differential reservoir equations. Based on the numerical simulations, the saturation and pressure equations are calculated by the iterative alternating direction implicit method and the iterative alternating direction explicit method, respectively, according to the finite difference assumption. However, to understand the displacement of oil by water and the amount of water dispersion in the reservoir better, an interpolated contour line of the water distribution of the five-spot pattern, that provides an approximate solution which agrees well with the experimental results, is also presented. Finally, a computer program is developed to calculate the equation for pressure and water saturation and to draw the pressure contour line and water distribution contour line for the reservoir. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulation" title="numerical simulation">numerical simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=immiscible" title=" immiscible"> immiscible</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20difference" title=" finite difference"> finite difference</a>, <a href="https://publications.waset.org/abstracts/search?q=IADI" title=" IADI"> IADI</a>, <a href="https://publications.waset.org/abstracts/search?q=IDE" title=" IDE"> IDE</a>, <a href="https://publications.waset.org/abstracts/search?q=waterflooding" title=" waterflooding"> waterflooding</a> </p> <a href="https://publications.waset.org/abstracts/59679/two-dimensional-observation-of-oil-displacement-by-water-in-a-petroleum-reservoir-through-numerical-simulation-and-application-to-a-petroleum-reservoir" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59679.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">331</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1005</span> Recovery of Petroleum Reservoir by Waterflooding Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zabihullah%20Mahdi">Zabihullah Mahdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Khwaja%20Naweed%20Seddiqi"> Khwaja Naweed Seddiqi</a>, <a href="https://publications.waset.org/abstracts/search?q=Shigeo%20Honma"> Shigeo Honma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Through many types of research and practical studies, it has been identified that the average oil recovery factor of a petroleum reservoir is about 30 to 35 %. This study is focused on enhanced oil recovery by laboratory experiment and graphical investigation based on Buckley-Leverett theory. Horizontal oil displacement by water, in a petroleum reservoir is analyzed under the Buckley-Leverett frontal displacement theory. The extraction and prerequisite of this theory are based and pursued focusing on the key factors that control displacement. The theory is executable to the waterflooding method, which is generally employed in petroleum engineering reservoirs to sustain oil production recovery, and the techniques for evaluating the average water saturation behind the water front and the oil recovery factors in the reservoirs are presented. In this paper, the Buckley-Leverett theory handled to an experimental model and the amount of recoverable oil are investigated to be over 35%. The irreducible water saturation, viz. connate water saturation, in the reservoir is also a significant inspiration for the recovery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Buckley-Leverett%20theory" title="Buckley-Leverett theory">Buckley-Leverett theory</a>, <a href="https://publications.waset.org/abstracts/search?q=waterflooding%20technique" title=" waterflooding technique"> waterflooding technique</a>, <a href="https://publications.waset.org/abstracts/search?q=petroleum%20engineering" title=" petroleum engineering"> petroleum engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=immiscible%20displacement" title=" immiscible displacement"> immiscible displacement</a> </p> <a href="https://publications.waset.org/abstracts/59677/recovery-of-petroleum-reservoir-by-waterflooding-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59677.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">257</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1004</span> Application of Waterflooding to the Kashkari Oil Field in Northern Afghanistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zabihullah%20Mahdi">Zabihullah Mahdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Nayab"> Mahdi Nayab</a>, <a href="https://publications.waset.org/abstracts/search?q=Sadaf%20Jalal"> Sadaf Jalal</a>, <a href="https://publications.waset.org/abstracts/search?q=Navid%20Seddiqi"> Navid Seddiqi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hydrocarbons represent an important natural resource for the rehabilitation and sustainable development of Afghanistan. In this paper, the use of waterflooding is demonstrated for the petroleum reservoirs of the Kashkari oil field in northern Afghanistan. The technique is based on the Buckley–Leverett frontal-displacement theory, which enables computation of the progress of the waterfront in the reservoir. The relative permeabilities of oil and water, the residual oil saturation, and the irreducible water saturation are obtained from a laboratory experiment. The technique is applied to the laboratory plane-reservoir model to investigate the displacement mechanism and is then compared with the theoretical calculation. Lastly, the technique is applied to the Kashkari oil field to predict the feasible amount of oil that could be produced from this reservoir. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Buckley%E2%80%93Leverett" title="Buckley–Leverett">Buckley–Leverett</a>, <a href="https://publications.waset.org/abstracts/search?q=waterflooding" title=" waterflooding"> waterflooding</a>, <a href="https://publications.waset.org/abstracts/search?q=petroleum%20reservoir%20engineering" title=" petroleum reservoir engineering"> petroleum reservoir engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=two-phase%20flow" title=" two-phase flow"> two-phase flow</a>, <a href="https://publications.waset.org/abstracts/search?q=immiscible%20displacement" title=" immiscible displacement"> immiscible displacement</a>, <a href="https://publications.waset.org/abstracts/search?q=porous%20media" title=" porous media"> porous media</a>, <a href="https://publications.waset.org/abstracts/search?q=relative%20permeability" title=" relative permeability"> relative permeability</a> </p> <a href="https://publications.waset.org/abstracts/111058/application-of-waterflooding-to-the-kashkari-oil-field-in-northern-afghanistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111058.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">203</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1003</span> Measuring of the Volume Ratio of Two Immiscible Liquids Using Electrical Impedance Tomography</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jiri%20Primas">Jiri Primas</a>, <a href="https://publications.waset.org/abstracts/search?q=Michal%20Malik"> Michal Malik</a>, <a href="https://publications.waset.org/abstracts/search?q=Darina%20Jasikova"> Darina Jasikova</a>, <a href="https://publications.waset.org/abstracts/search?q=Michal%20Kotek"> Michal Kotek</a>, <a href="https://publications.waset.org/abstracts/search?q=Vaclav%20Kopecky"> Vaclav Kopecky</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Authors of this paper discuss the measuring of volume ratio of two immiscible liquids in the homogenous mixture using the industrial Electrical Impedance Tomography (EIT) system ITS p2+.

When a sequence of instantaneous stimuli falls in this short interval of time, observers perceive a compresence of events in succession and the temporal order depends on the qualitative relationships between the perceptual properties of the events. Two experiments were carried out to study the influence of perceptual grouping, with and without temporal displacement, on the duration of auditory sequences. The psychophysical method of adjustment was adopted. The first experiment investigated the effect of temporal displacement of a white noise on sequence duration. The second experiment investigated the effect of temporal displacement, along the pitch dimension, on temporal shortening of sequence. The results suggest that the temporal order of sounds, in the case of temporal displacement, is organized along the pitch dimension. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=time%20perception" title="time perception">time perception</a>, <a href="https://publications.waset.org/abstracts/search?q=perceptual%20present" title=" perceptual present"> perceptual present</a>, <a href="https://publications.waset.org/abstracts/search?q=temporal%20displacement" title=" temporal displacement"> temporal displacement</a>, <a href="https://publications.waset.org/abstracts/search?q=Gestalt%20laws%20of%20perceptual%20organization" title=" Gestalt laws of perceptual organization"> Gestalt laws of perceptual organization</a> </p> <a href="https://publications.waset.org/abstracts/76211/perceptual-organization-within-temporal-displacement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76211.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">250</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1001</span> Vaporization of a Single N-Pentane Liquid Drop in a Flowing Immiscible Liquid Media</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hameed%20B.%20Mahood">Hameed B.

Thirty and two different models were studied by different parameters. These studies could calculate displacement at any height of the wall for frictional-cohesive soils. The main purpose of this research is to determine the most effective soil characteristics in reducing the wall displacement. Comparing different models showed that the overall increase in internal friction angle, angle of friction between soil and wall and modulus of elasticity reduce the replacement of the wall. In addition, increase in special weight of soil will increase the wall displacement. Based on results, it can be said that all wall displacements were overturning and in the backfill, soil was bulging. Results show that the highest impact is seen in reducing wall displacement, internal friction angle, and the angle friction between soil and wall. One of the advantages of this study is taking into account all the parameters of the soil and walls replacement distribution in wall and backfill soil. In this paper, using the finite element method and considering all parameters of the soil, we investigated the impact of soil parameter in wall displacement. The aim of this study is to provide the best conditions in reducing the wall displacement and displacement wall and soil distribution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=retaining%20wall" title="retaining wall">retaining wall</a>, <a href="https://publications.waset.org/abstracts/search?q=fem" title=" fem"> fem</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20and%20wall%20interaction" title=" soil and wall interaction"> soil and wall interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=angle%20of%20internal%20friction%20of%20the%20soil" title=" angle of internal friction of the soil"> angle of internal friction of the soil</a>, <a href="https://publications.waset.org/abstracts/search?q=wall%20displacement" title=" wall displacement"> wall displacement</a> </p> <a href="https://publications.waset.org/abstracts/44288/studying-the-impact-of-soil-characteristics-in-displacement-of-retaining-walls-using-finite-element" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44288.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">387</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">999</span> Vulnerability Assessment of Reinforced Concrete Frames Based on Inelastic Spectral Displacement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chao%20Xu">Chao Xu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Selecting ground motion intensity measures reasonably is one of the very important issues to affect the input ground motions selecting and the reliability of vulnerability analysis results. In this paper, inelastic spectral displacement is used as an alternative intensity measure to characterize the ground motion damage potential. The inelastic spectral displacement is calculated based modal pushover analysis and inelastic spectral displacement based incremental dynamic analysis is developed. Probability seismic demand analysis of a six story and an eleven story RC frame are carried out through cloud analysis and advanced incremental dynamic analysis. The sufficiency and efficiency of inelastic spectral displacement are investigated by means of regression and residual analysis, and compared with elastic spectral displacement. Vulnerability curves are developed based on inelastic spectral displacement. The study shows that inelastic spectral displacement reflects the impact of different frequency components with periods larger than fundamental period on inelastic structural response. The damage potential of ground motion on structures with fundamental period prolonging caused by structural soften can be caught by inelastic spectral displacement. To be compared with elastic spectral displacement, inelastic spectral displacement is a more sufficient and efficient intensity measure, which reduces the uncertainty of vulnerability analysis and the impact of input ground motion selection on vulnerability analysis result. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vulnerability" title="vulnerability">vulnerability</a>, <a href="https://publications.waset.org/abstracts/search?q=probability%20seismic%20demand%20analysis" title=" probability seismic demand analysis"> probability seismic demand analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=ground%20motion%20intensity%20measure" title=" ground motion intensity measure"> ground motion intensity measure</a>, <a href="https://publications.waset.org/abstracts/search?q=sufficiency" title=" sufficiency"> sufficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=efficiency" title=" efficiency"> efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=inelastic%20time%20history%20analysis" title=" inelastic time history analysis"> inelastic time history analysis</a> </p> <a href="https://publications.waset.org/abstracts/48653/vulnerability-assessment-of-reinforced-concrete-frames-based-on-inelastic-spectral-displacement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48653.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">353</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">998</span> Numerical Modelling of Immiscible Fluids Flow in Oil Reservoir Rocks during Enhanced Oil Recovery Processes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zahreddine%20Hafsi">Zahreddine Hafsi</a>, <a href="https://publications.waset.org/abstracts/search?q=Manoranjan%20Mishra"> Manoranjan Mishra </a>, <a href="https://publications.waset.org/abstracts/search?q=Sami%20Elaoud">Sami Elaoud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ensuring the maximum recovery rate of oil from reservoir rocks is a challenging task that requires preliminary numerical analysis of different techniques used to enhance the recovery process. After conventional oil recovery processes and in order to retrieve oil left behind after the primary recovery phase, water flooding in one of several techniques used for enhanced oil recovery (EOR). In this research work, EOR via water flooding is numerically modeled, and hydrodynamic instabilities resulted from immiscible oil-water flow in reservoir rocks are investigated. An oil reservoir is a porous medium consisted of many fractures of tiny dimensions. For modeling purposes, the oil reservoir is considered as a collection of capillary tubes which provides useful insights into how fluids behave in the reservoir pore spaces. Equations governing oil-water flow in oil reservoir rocks are developed and numerically solved following a finite element scheme. Numerical results are obtained using Comsol Multiphysics software. The two phase Darcy module of COMSOL Multiphysics allows modelling the imbibition process by the injection of water (as wetting phase) into an oil reservoir. Van Genuchten, Brooks Corey and Levrett models were considered as retention models and obtained flow configurations are compared, and the governing parameters are discussed. For the considered retention models it was found that onset of instabilities viz. fingering phenomenon is highly dependent on the capillary pressure as well as the boundary conditions, i.e., the inlet pressure and the injection velocity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=capillary%20pressure" title="capillary pressure">capillary pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=EOR%20process" title=" EOR process"> EOR process</a>, <a href="https://publications.waset.org/abstracts/search?q=immiscible%20flow" title=" immiscible flow"> immiscible flow</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20modelling" title=" numerical modelling"> numerical modelling</a> </p> <a href="https://publications.waset.org/abstracts/102040/numerical-modelling-of-immiscible-fluids-flow-in-oil-reservoir-rocks-during-enhanced-oil-recovery-processes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102040.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">131</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">997</span> Remediation and Health: A Systematic Review of the Role of Resulting Displacement in Damaging Health and Wellbeing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rupert%20G.%20S.%20Legg">Rupert G. S. Legg</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The connection between poor health outcomes and living near contaminated land has long been understood. Less examined has been the impact of remediation on residents’ health. The cleaning process undoubtedly changes the local area in which it occurs, leading to the possibility that local housing and rental prices could increase resulting in the displacement of those least able to cope. Whether or not this potential displacement resulting from remediation has a considerable impact on health remains unknown. This review aims to determine how these health effects have been approached in the health geography literature. A systematic review of health geographies literature was conducted, searching for two-word clusters: ‘health’ and ‘remediation’ (100 articles); and ‘health’, ‘displacement’ and ‘gentrification’ (43 articles). 43 articles were selected for their relevance (7 from the first cluster, 20 from the second, and 16 from those cited within the reviewed articles). Several of the reviewed cases identified that potential displacement was a contributor to stress and worry in residents living near remediation projects. Likewise, the experience of displacement in other cases beyond remediation was linked with several mental health issues. However, no remediation cases followed-up on the ultimate effects of experiencing displacement on residents’ health. A reason identified for this was a tendency for reviewed studies to adopt a contextual or compositional approach, as opposed to a relational approach, which is more concerned with dimensions of mobility and temporality. Given that remediation and displacement both involve changing mobility and temporality, focussing solely on contextual or compositional factors is problematic. This review concludes by suggesting that more thorough, relational research is conducted into the extent to which potential displacement resulting from remediation affects health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contamination" title="contamination">contamination</a>, <a href="https://publications.waset.org/abstracts/search?q=displacement" title=" displacement"> displacement</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20geography" title=" health geography"> health geography</a>, <a href="https://publications.waset.org/abstracts/search?q=remediation" title=" remediation"> remediation</a> </p> <a href="https://publications.waset.org/abstracts/99490/remediation-and-health-a-systematic-review-of-the-role-of-resulting-displacement-in-damaging-health-and-wellbeing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99490.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">162</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">996</span> Impact of Forced Displacement on Place Attachment and Home Perception of Internally Displaced Turkish Cypriots </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Makbule%20Oktay">Makbule Oktay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Home is a significant entity in people’s lives. It is a place that provides shelter to people and a place to which one feels a sense of attachment and belonging. It is an entity that people develop feelings and meaning to it. People – place bond, or in other words place attachment, and home perception might alter as a consequence of lifetime experiences. Thus, forced displacement appears as a dramatic experience for people who lose their homes, belongings and communities. It impacts people who involuntarily leave their homes and belongings behind, experience physical, social, cultural and economic disruption and are forced to settle in an unfamiliar environment. Place attachment and home perception of internally displaced people who involuntarily leave their homes might be different from those who haven’t experience forced displacement. Although place attachment, meaning of home and forced displacement are the subjects that have been broadly studied, there is a lack of studies which question the relation between the three subjects in general and on Turkish Cypriot case in particular. Considering this, it is the aim of this paper to investigate the impact of forced displacement to internally displaced people’s attachment to a particular place and home perception. To do so, the study focuses on internally displaced Turkish Cypriots who have been internally displaced as a result of conflict. Interview and questionnaire as two of the commonly used techniques in the place attachment and home perception studies have been used in this study too. The results of the study indicate that internal displacement has an apparent impact on place attachment of forcibly displaced people. As a consequence of longstanding displacement, forcibly displaced people developed multiple attachments. Compared to people who have not experienced displacement, forcibly displaced people have low attachments. Forced displacement does not strongly impact the home perception in terms of meaning of home in longstanding displacement situations even though displacement-related meanings of home exist. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=forcibly%20displaced%20people" title="forcibly displaced people">forcibly displaced people</a>, <a href="https://publications.waset.org/abstracts/search?q=home%20perception" title=" home perception"> home perception</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20displacement" title=" internal displacement"> internal displacement</a>, <a href="https://publications.waset.org/abstracts/search?q=place%20attachment" title=" place attachment"> place attachment</a>, <a href="https://publications.waset.org/abstracts/search?q=Turkish%20Cypriots" title=" Turkish Cypriots"> Turkish Cypriots</a> </p> <a href="https://publications.waset.org/abstracts/123839/impact-of-forced-displacement-on-place-attachment-and-home-perception-of-internally-displaced-turkish-cypriots" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123839.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">217</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">995</span> Displacement Due to Natural Disasters Vis-à-Vis Policy Framework: Case Study of Mising Community of Majuli, Assam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mausumi%20Chetia">Mausumi Chetia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the main causes of impoverishment of the rural areas of Assam has been the recurrent floods and riverbank erosion. One of the life-changing consequences is displacement. This results not only in a loss of livelihoods but also has wide-reaching socio-economic and cultural effects. Thus, due to such disasters, not only families but communities too are being displaced at large. This compels them to find temporary shelter and begin life from scratch. The role of the state has been highly negligible, with a displacement not being perceived as an ‘issue’ to be addressed. A more holistic approach is thus needed to take socio-economic, cultural, political as well as ecological considerations into account. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=displacement" title="displacement">displacement</a>, <a href="https://publications.waset.org/abstracts/search?q=policy-framework" title=" policy-framework"> policy-framework</a>, <a href="https://publications.waset.org/abstracts/search?q=human-induced%20disasters" title=" human-induced disasters"> human-induced disasters</a>, <a href="https://publications.waset.org/abstracts/search?q=marginalised%20communities" title=" marginalised communities"> marginalised communities</a>, <a href="https://publications.waset.org/abstracts/search?q=India" title=" India"> India</a>, <a href="https://publications.waset.org/abstracts/search?q=Assam" title=" Assam"> Assam</a> </p> <a href="https://publications.waset.org/abstracts/69872/displacement-due-to-natural-disasters-vis-a-vis-policy-framework-case-study-of-mising-community-of-majuli-assam" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69872.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">275</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">994</span> Political Economy of Internal Dispalcement, Migration and Human Security in Zimbabwe: 1800 to Present Day</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chupicai%20Manuel">Chupicai Manuel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this article is to examine the political economy and history of internal displacement, migration and human security in Zimbabwe from 1800 to present day.

The core samples of this oil field were taken out from well No-21<sup>st</sup>, and the relative permeability and fractional flow are analyzed. Steady state flow laboratory experiments are performed to empirically obtain the fractional flow curves and relative permeability in different water saturation ratio. The relative permeability represents the simultaneous flow behavior in the reservoir. The fractional flow approach describes the individual phases as fractional of the total flow. The fractional flow curve interprets oil displacement by water, and from the tangent of fractional flow curve can find out the average saturation behind the water front flow saturation. Therefore, relative permeability and fractional flow curves are suitable for describing the displacement of oil by water in a petroleum reservoir. The effects of irreducible water saturation, residual oil saturation on the displaceable amount of oil are investigated through Buckley-Leveret analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fractional%20flow" title="fractional flow">fractional flow</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20displacement" title=" oil displacement"> oil displacement</a>, <a href="https://publications.waset.org/abstracts/search?q=relative%20permeability" title=" relative permeability"> relative permeability</a>, <a href="https://publications.waset.org/abstracts/search?q=simultaneously%20flow" title=" simultaneously flow"> simultaneously flow</a> </p> <a href="https://publications.waset.org/abstracts/59190/oil-displacement-by-water-in-hauterivian-sandstone-reservoir-of-kashkari-oil-field" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59190.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">392</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">992</span> New Modification Negative Stiffness Device with Constant Force-Displacement Characteristic for Seismic Protection of Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Huan%20Li">Huan Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Jianchun%20Li"> Jianchun Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Yancheng%20Li"> Yancheng Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Yang%20Yu"> Yang Yu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As a seismic protection method of civil and engineering structures, weakening and damping is effective during the elastic region, while it somehow leads to the early yielding of the entire structure accompanying with large excursions and permanent deformations. Adaptive negative stiffness device is attractive for realizing yielding property without changing the stiffness of the primary structure. In this paper, a new modification negative stiffness device (MNSD) with constant force-displacement characteristic is proposed by combining a magnetic negative stiffness spring, a piecewise linear positive spring and a passive damper with a certain adaptive stiffness device. The proposed passive control MNSD preserves no effect under small excitation. When the displacement amplitude increases beyond the pre-defined yielding point, the force-displacement characteristics of the system with MNSD will keep constant. The seismic protection effect of the MNSD is evaluated by employing it to a single-degree-of-freedom system under sinusoidal excitation, and real earthquake waves. By comparative analysis, the system with MNSD performs better on reducing acceleration and displacement response under different displacement amplitudes than the scenario without it and the scenario with unmodified certain adaptive stiffness device. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=negative%20stiffness" title="negative stiffness">negative stiffness</a>, <a href="https://publications.waset.org/abstracts/search?q=adaptive%20stiffness" title=" adaptive stiffness"> adaptive stiffness</a>, <a href="https://publications.waset.org/abstracts/search?q=weakening%20and%20yielding" title=" weakening and yielding"> weakening and yielding</a>, <a href="https://publications.waset.org/abstracts/search?q=constant%20force-displacement%20characteristic" title=" constant force-displacement characteristic"> constant force-displacement characteristic</a> </p> <a href="https://publications.waset.org/abstracts/125646/new-modification-negative-stiffness-device-with-constant-force-displacement-characteristic-for-seismic-protection-of-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125646.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">159</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">991</span> Investigation of the Speckle Pattern Effect for Displacement Assessments by Digital Image Correlation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salim%20%C3%87al%C4%B1%C5%9Fkan">Salim Çalışkan</a>, <a href="https://publications.waset.org/abstracts/search?q=Hakan%20Aky%C3%BCz"> Hakan Akyüz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Digital image correlation has been accustomed as a versatile and efficient method for measuring displacements on the article surfaces by comparing reference subsets in undeformed images with the define target subset in the distorted image.

Therefore, a proper bra design and fit can help to control excessive breast motion to prevent the over-stretching of the connective tissues. Nevertheless, bra fit problems, such as excessively high tension of the shoulder straps and a tight underband could have substantially negative effects on the wear comfort and health of the wearer. The purpose of this study is to, therefore, examine the effects of bra band tension on breast displacement. Usually, human wear trials are carried out, but there are inconsistencies during testing. Therefore, a soft manikin torso is used to examine breast displacement at walking speeds of 2.30 km/h and 4.08 km/h. The breast displacement itself is determined by using a VICON motion capture system. The 3D geometric changes of the underwire bra band tension and the corresponding control of breast movement are also analyzed by using a 3D handheld scanner along with Rapidform software. The results indicate that an appropriate bra band tension can help to reduce breast displacement and provide a comfortable angle for the underwire. The findings can be used by designers and bra engineers as a reference source to advance bra design and development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bra%20band" title="bra band">bra band</a>, <a href="https://publications.waset.org/abstracts/search?q=bra%20features" title=" bra features"> bra features</a>, <a href="https://publications.waset.org/abstracts/search?q=breast%20displacement" title=" breast displacement"> breast displacement</a>, <a href="https://publications.waset.org/abstracts/search?q=underwire%20angle" title=" underwire angle"> underwire angle</a> </p> <a href="https://publications.waset.org/abstracts/93789/influence-of-bra-band-tension-and-underwire-angles-on-breast-motion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93789.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">250</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">989</span> An Improved Mesh Deformation Method Based on Radial Basis Function</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xuan%20Zhou">Xuan Zhou</a>, <a href="https://publications.waset.org/abstracts/search?q=Litian%20Zhang"> Litian Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Shuixiang%20Li"> Shuixiang Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mesh deformation using radial basis function interpolation method has been demonstrated to produce quality meshes with relatively little computational cost using a concise algorithm. However, it still suffers from the limited deformation ability, especially in large deformation. In this paper, a pre-displacement improvement is proposed to improve the problem that illegal meshes always appear near the moving inner boundaries owing to the large relative displacement of the nodes near inner boundaries. In this improvement, nodes near the inner boundaries are first associated to the near boundary nodes, and a pre-displacement based on the displacements of associated boundary nodes is added to the nodes near boundaries in order to make the displacement closer to the boundary deformation and improve the deformation capability. Several 2D and 3D numerical simulation cases have shown that the pre-displacement improvement for radial basis function (RBF) method significantly improves the mesh quality near inner boundaries and deformation capability, with little computational burden increasement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mesh%20deformation" title="mesh deformation">mesh deformation</a>, <a href="https://publications.waset.org/abstracts/search?q=mesh%20quality" title=" mesh quality"> mesh quality</a>, <a href="https://publications.waset.org/abstracts/search?q=background%20mesh" title=" background mesh"> background mesh</a>, <a href="https://publications.waset.org/abstracts/search?q=radial%20basis%20function" title=" radial basis function"> radial basis function</a> </p> <a href="https://publications.waset.org/abstracts/65928/an-improved-mesh-deformation-method-based-on-radial-basis-function" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65928.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">366</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">988</span> Design and Optimization of Soil Nailing Construction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fereshteh%20Akbari">Fereshteh Akbari</a>, <a href="https://publications.waset.org/abstracts/search?q=Farrokh%20Jalali%20Mosalam"> Farrokh Jalali Mosalam</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Hedayatifar"> Ali Hedayatifar</a>, <a href="https://publications.waset.org/abstracts/search?q=Amirreza%20Aminjavaheri"> Amirreza Aminjavaheri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The soil nailing is an effective method to stabilize slopes and retaining structures.

The study is based on the analysis of single degree of freedom (SDOF) systems with elasto-plastic hysteretic behavior. Several seismic ground motions corresponding to subduction events with magnitudes equal to or greater than 6 and recorded in different stations of Mexico City are used. The proposed expression involves the ratio of elastic and inelastic pseudo-aceleration spectra, and depends on factors such the ductility demand and the vibration period of the structural system.

Performance-based design aims to design the structures to achieve specified performance based on the damage limit states. This damage limit is more restrictive limit than life safety and needs to be carefully estimated to avoid damage in piers due to failure in transverse reinforcement. In this paper, a different perspective of damage limit states has been explored by integrating two damage control material limit state, concrete and reinforcement by introduced parameters such as expected yield stress of transverse reinforcement where peak tension strain prior to bar buckling is introduced in a recent study. The different perspective of damage limit states with modified yield displacement and the modified plastic-hinge length is used in order to predict damage-control target displacement for reinforced concreate (RC) bridge pier. Three-dimensional (3D) finite element (FE) model has been developed for estimating damage target displacement to validate proposed damage limit states. The result from 3D FE analysis was validated with experimental study found in the literature. The validated model then was applied to predict the damage target displacement for RC bridge pier and to validate the proposed study. The tensile strain on reinforcement and compression on concrete were used to determine the predicted damage target displacement and compared with the proposed study. The result shows that the proposed damage limit states were efficient in predicting damage-control target displacement consistent with FE simulations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=damage-control%20target%20displacement" title="damage-control target displacement">damage-control target displacement</a>, <a href="https://publications.waset.org/abstracts/search?q=damage%20limit%20states" title=" damage limit states"> damage limit states</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20concrete%20bridge%20pier" title=" reinforced concrete bridge pier"> reinforced concrete bridge pier</a>, <a href="https://publications.waset.org/abstracts/search?q=yield%20displacement" title=" yield displacement"> yield displacement</a> </p> <a href="https://publications.waset.org/abstracts/99016/analysis-of-a-damage-control-target-displacement-of-reinforced-concrete-bridge-pier-for-seismic-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99016.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">157</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">984</span> Facile Synthesis of Metal Nanoparticles on Graphene via Galvanic Displacement Reaction for Sensing Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juree%20Hong">Juree Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanggeun%20Lee"> Sanggeun Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Jungmok%20Seo"> Jungmok Seo</a>, <a href="https://publications.waset.org/abstracts/search?q=Taeyoon%20Lee"> Taeyoon Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We report a facile synthesis of metal nano particles (NPs) on graphene layer via galvanic displacement reaction between graphene-buffered copper (Cu) and metal ion-containing salts.

Bartal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A large empirical evidence points to sizable lifetime earnings losses associated with the displacement of tenured workers. The causes of these losses are still not well-understood. Existing explanations are heavily based on human capital depreciation during non-employment spells. In this paper, a new avenue is explored. Evidence on the role of household liquidity constraints in accounting for the persistence of post-displacement earning losses is provided based on SIPP data. Then, a directed search and matching model with endogenous human capital and wealth accumulation is introduced. The model is computationally tractable thanks to its block-recursive structure and highlights a non-trivial, yet intuitive, interaction between wealth and human capital. Constrained workers tend to accept jobs with low firm-sponsored training because the latter are (endogenously) easier to find. This new channel provides a plausible explanation for why young (highly constrained) workers suffer persistent scars after displacement. Finally, the model is calibrated on US data to show that the interplay between wealth and human capital is crucial to replicate the observed lifecycle pattern of earning losses.

Therefor, even in the era of globalisation no nation-state is ready to compromise with its territorial boundaries. The problem of migration and displacement has generated a range of socio-political, economic, ethnic, and communal tensions in India in general and northeastern States in particular. In such situation it becomes unpreventable to look over the issue so that a viable elucidation may emerge. The present paper is an attempt to understand the impact of Bangladeshi and Nepali migration to North-Eastern states of India through historical and analytical methods. In this course it will look into the emergence of the migration and displacement problem, its causes, impacts on security and other issues of national interest especially when the migration is illegal and poses multi-layered challenges to the Indian state.
