nitroglycerin manufacturing efficiency through simulation, recover nitroglycerin from the storage facility, and enhance nitroglycerine recovery and purge systems. It was found that the problem was nitroglycerin reflux. Therefore, the researcher created three alternatives to solve the problem. The system of Nitroglycerine Recovery and Purge was then simulated using the FlexSim program, and each alternative was tested. The results demonstrate that the alternative system-led Nitroglycerine Recovery and Nitroglycerine Purge System collaborate to produce Nitroglycerine, which is more efficient than other alternatives and can reduce production time. It can also improve the recovery of nitroglycerin. It also serves as a guideline for developing a real-world system and modeling it for training staff without wasting raw chemical materials or fuel energy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=efficiency%20increase" title="efficiency increase">efficiency increase</a>, <a href="https://publications.waset.org/abstracts/search?q=nitroglycerine%20recovery%20and%20purge%20system" title=" nitroglycerine recovery and purge system"> nitroglycerine recovery and purge system</a>, <a href="https://publications.waset.org/abstracts/search?q=production%20improvement" title=" production improvement"> production improvement</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a> </p> <a href="https://publications.waset.org/abstracts/161091/the-application-of-simulation-techniques-to-enhance-nitroglycerin-production-efficiency-a-case-study-of-the-military-explosive-factory-in-nakhon-sawan-province" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161091.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">129</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">5975</span> The Initiator Matters in Service Co-Recovery: Investigation on Attribution and Satisfaction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chia-Ching%20Tsai">Chia-Ching Tsai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the literature, the positive effect of service co-recovery has been evidenced, and which customers’ attribution is the key successful factor has also been indicated.

A realistic thematic analytical approach was used to interpret the findings of 44 semi-structured interviews of athletes who competed at high school, college, and professional levels of competition. Thematic analysis validated by a self-rating scale demonstrated athletes cross a series of emotional thresholds during their injury rehabilitation process. Results showed athletes crossed two to six emotional thresholds before positive emotion and coping were consistently experienced following their injury. Athletes reported being unequipped to cope with negative emotional intensity, the longevity of recovery, and enduring depression during long-term rehabilitation. Positive emotional recovery was expected no sooner than nine months and up to 2.5 years following a sports injury. In addition, 100% of athletes received no psychological skills training (PST) for coping and recovery, and 93% of athletes indicated passive psychological coping strategies in the first month following injury, which extended their time to recover. Athletes recommended immediate, realistic, and evidence-based strategies benefitting the emotional recovery of severely injured athletes emotional recovery to improve athletes' emotional well-being during long-term rehabilitation and enhance their return to sport. Future experimental research might compare the post-PST program that emerged from this study to determine its efficacy in improving the recovery of severely injured athletes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sports" title="sports">sports</a>, <a href="https://publications.waset.org/abstracts/search?q=injury" title=" injury"> injury</a>, <a href="https://publications.waset.org/abstracts/search?q=rehabilitation" title=" rehabilitation"> rehabilitation</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological%20skills%20training" title=" psychological skills training"> psychological skills training</a>, <a href="https://publications.waset.org/abstracts/search?q=coping" title=" coping"> coping</a> </p> <a href="https://publications.waset.org/abstracts/154222/psychological-skills-training-for-severely-injured-athletes-to-enhance-recovery-and-return-to-sport" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154222.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">135</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">5973</span> The Impact of Level and Consequence of Service Co-Recovery on Post-Recovery Satisfaction and Repurchase Intent</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chia-Ching%20Tsai">Chia-Ching Tsai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In service delivery, interpersonal interaction is the key to customer satisfaction, and apparently, the factor of human is critical in service delivery. Besides, customers quite care about the consequences of co-recovery. Thus, this research focuses on service failure caused by other customers and uses a 2x2 factorial design to investigate the impact of consequence and level of service co-recovery on post-recovery satisfaction and repurchase intent. 150 undergraduates were recruited as participants, and assigned to one of the four cells randomly. Every participant was requested to read the scenario and then rated the post-recovery satisfaction and repurchase intent. The results show that under the condition of failed co-recovery, level of co-recovery has no effect on post-recovery satisfaction, while under the condition of successful co-recovery, high-level co-recovery causes significantly higher post-recovery satisfaction than low-level co-recovery. Moreover, post-recovery satisfaction has significantly positive impact on repurchase intent. In the system of service delivery, customers interact with other customers frequently. Therefore, comparing with the literature, this research focuses on the service failure caused by other customers. This research also supplies a better understanding of customers’ view on consequences of different levels of co-recovery, which is helpful for the practitioners to make use of co-recovery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=service%20failure" title="service failure">service failure</a>, <a href="https://publications.waset.org/abstracts/search?q=service%20co-recovery" title=" service co-recovery"> service co-recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=consequence%20of%20co-recovery" title=" consequence of co-recovery"> consequence of co-recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=level%20of%20co-recovery" title=" level of co-recovery"> level of co-recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=post-recovery%20satisfaction" title=" post-recovery satisfaction"> post-recovery satisfaction</a>, <a href="https://publications.waset.org/abstracts/search?q=repurchase%20intent" title=" repurchase intent"> repurchase intent</a> </p> <a href="https://publications.waset.org/abstracts/78948/the-impact-of-level-and-consequence-of-service-co-recovery-on-post-recovery-satisfaction-and-repurchase-intent" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78948.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">420</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">5972</span> Autonomic Recovery Plan with Server Virtualization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Hameed">S.

This autonomic solution would also support disaster management, testing, and development of the recovery site. In this research, a workflow plan is proposed for supporting disaster recovery with virtualization providing virtual monitoring, requirements engineering, solution decision making, quality testing, and disaster management.

To solve this problem at global level, sequestration of CO2 in deep and unmineable coal seams has come out as one of the attractive alternatives to reduce concentration in atmosphere. This sequestration technology is not only going to help in storage of CO2 beneath the sub-surface but is also playing a major role in enhancing the coal bed methane recovery (ECBM) by displacing the adsorbed methane. This paper provides the answers for the need of CO2 injection in coal seams and how recovery is enhanced. We have discussed the recent development in enhancing the coal bed methane recovery and the economic scenario of the same. The effect of injection on the coal reservoir has also been discussed. Coal is a good absorber of CO2. That is why the sequestration of CO2 is emerged out to be a great approach, not only for storage purpose but also for enhancing coal bed methane recovery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=global%20warming" title="global warming">global warming</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20dioxide%20%28CO2%29" title=" carbon dioxide (CO2)"> carbon dioxide (CO2)</a>, <a href="https://publications.waset.org/abstracts/search?q=CO2%20sequestration" title=" CO2 sequestration"> CO2 sequestration</a>, <a href="https://publications.waset.org/abstracts/search?q=enhance%20coal%20bed%20methane%20%28ECBM%29" title=" enhance coal bed methane (ECBM)"> enhance coal bed methane (ECBM)</a> </p> <a href="https://publications.waset.org/abstracts/17429/co2-sequestration-for-enhanced-coal-bed-methane-recovery-a-new-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17429.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">505</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">5970</span> The Beneficial Effects of Hydrotherapy for Recovery from Team Sport – A Meta-Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Trevor%20R.%20Higgins">Trevor R. Higgins</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To speed/enhance recovery from sport, cold water immersion (CWI) and contrast water therapy (CWT) have become common practice within the high-level team sport. Initially, research into CWI and CWT protocols and recovery was sparse; athletes relied solely upon an anecdotal support. However, an increase into recovery research has occurred. A number of reviews have subsequently been conducted to clarify scientific evidence. However, as the nature of physiological stress and training status of participants will impact on results, an opportunity existed to narrow the focus to a more exacting review evaluating hydrotherapy for recovery in a team sport. A Boolean logic [AND] keyword search of databases was conducted: SPORTDiscus; AMED; CINAHL; MEDLINE. Data was extracted and the standardized mean differences were calculated with 95% CI. The analysis of pooled data was conducted using a random-effect model, with Heterogeneity assessed using I2. 23 peer reviewed papers (n=606) met the criteria. Meta-analyses results indicated CWI was likely beneficial for recovery at 24h (Countermovement Jump (CMJ): p= 0.05, CI -0.004 to 0.578; All-out sprint: p=0.02, -0.056 to 0.801; DOMS: p=0.08, CI -0.092 to 1.936) and at 72h (accumulated sprinting: p=0.07, CI -0.062 to 1.209; DOMS: p=0.09, CI -0.121 to 1.555) following team sport. Whereas CWT was likely beneficial for recovery at 1h (CMJ: p= 0.07, CI -0.004 to 0.863) and at 48h (fatigue: p=0.04, CI 0.013 to 0.942) following team sport. Athlete’s perceptions of muscle soreness and fatigue are enhanced with CWI and/or CWT, however even though CWI and CWT were beneficial in attenuating decrements in neuromuscular performance 24 hours following team sport, indications are those benefits were no longer Sydney evident 48 hours following team sport. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cold%20water%20immersion" title="cold water immersion">cold water immersion</a>, <a href="https://publications.waset.org/abstracts/search?q=contrast%20water%20therapy" title=" contrast water therapy"> contrast water therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=recovery" title=" recovery"> recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=team%20sport" title=" team sport"> team sport</a> </p> <a href="https://publications.waset.org/abstracts/33821/the-beneficial-effects-of-hydrotherapy-for-recovery-from-team-sport-a-meta-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33821.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">507</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">5969</span> Measurements of Recovery Stress and Recovery Strain of Ni-Based Shape Memory Alloys </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=W.%20J.%20Kim">W.

After HRDSR, both the recovery stress and strain were enhanced compared to the initial condition. The constitutive equation showing that the maximum recovery stress is a sole function of the recovery strain was developed based on the experimental data. The recovery strain increased as the yield stress increased. The maximum recovery stress increased with an increase in yield stress. The residual recovery stress was affected by the yield stress as well as the austenite-to-martensite transformation temperature. As the yield stress increased and as the martensitic transformation temperature decreased, the residual recovery stress increased. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high-ratio%20differential%20speed%20rolling" title="high-ratio differential speed rolling">high-ratio differential speed rolling</a>, <a href="https://publications.waset.org/abstracts/search?q=tensile%20testing" title=" tensile testing"> tensile testing</a>, <a href="https://publications.waset.org/abstracts/search?q=severe%20plastic%20deformation" title=" severe plastic deformation"> severe plastic deformation</a>, <a href="https://publications.waset.org/abstracts/search?q=shape%20memory%20alloys" title=" shape memory alloys"> shape memory alloys</a> </p> <a href="https://publications.waset.org/abstracts/69337/measurements-of-recovery-stress-and-recovery-strain-of-ni-based-shape-memory-alloys" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69337.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">5968</span> Blogging Towards Recovery: The Benefits of Blogging about Recovery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jayme%20R.%20Swanke">Jayme R.

The study’s participants engaged in a five-day adventure camp, known as Recovery Camp, alongside undergraduate health care students. An interpretive phenomenological approach was used as an exploratory method to interview 25 participants (n=25). Van Kaam’s structured analytical framework guided the analysis of the transcribed narratives. The findings provide insight into using therapeutic recreation to enhance personal mental health recovery. Recovery Camp was viewed by participants as having a transformational effect on forming positive social connectedness and improving their self-identity. Participants perceived the Recovery Camp experience as one that gave them a sense of purpose and increased their motivation to undertake further activities. The insights gained of the benefits of therapeutic recreation for people living with a mental illness can be used to promote purposeful community engagement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=interpretive%20phenomenology" title="interpretive phenomenology">interpretive phenomenology</a>, <a href="https://publications.waset.org/abstracts/search?q=lived%20experience" title=" lived experience"> lived experience</a>, <a href="https://publications.waset.org/abstracts/search?q=mental%20illness" title=" mental illness"> mental illness</a>, <a href="https://publications.waset.org/abstracts/search?q=personal%20mental%20health%20recovery" title=" personal mental health recovery"> personal mental health recovery</a> </p> <a href="https://publications.waset.org/abstracts/77029/the-lived-experience-of-people-with-a-mental-illness-of-their-engagement-in-therapeutic-recreation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77029.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">499</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">5966</span> Enhancing the Resilience of Combat System-Of-Systems Under Certainty and Uncertainty: Two-Phase Resilience Optimization Model and Deep Reinforcement Learning-Based Recovery Optimization Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xueming%20Xu">Xueming Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiahao%20Liu"> Jiahao Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Jichao%20Li"> Jichao Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Kewei%20Yang"> Kewei Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Minghao%20Li"> Minghao Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Bingfeng%20Ge"> Bingfeng Ge</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A combat system-of-systems (CSoS) comprises various types of functional combat entities that interact to meet corresponding task requirements in the present and future. Enhancing the resilience of CSoS holds significant military value in optimizing the operational planning process, improving military survivability, and ensuring the successful completion of operational tasks. Accordingly, this research proposes an integrated framework called CSoS resilience enhancement (CSoSRE) to enhance the resilience of CSoS from a recovery perspective. Specifically, this research presents a two-phase resilience optimization model to define a resilience optimization objective for CSoS. This model considers not only task baseline, recovery cost, and recovery time limit but also the characteristics of emergency recovery and comprehensive recovery. Moreover, the research extends it from the deterministic case to the stochastic case to describe the uncertainty in the recovery process. Based on this, a resilience-oriented recovery optimization method based on deep reinforcement learning (RRODRL) is proposed to determine a set of entities requiring restoration and their recovery sequence, thereby enhancing the resilience of CSoS. This method improves the deep Q-learning algorithm by designing a discount factor that adapts to changes in CSoS state at different phases, simultaneously considering the network’s structural and functional characteristics within CSoS. Finally, extensive experiments are conducted to test the feasibility, effectiveness and superiority of the proposed framework. The obtained results offer useful insights for guiding operational recovery activity and designing a more resilient CSoS. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=combat%20system-of-systems" title="combat system-of-systems">combat system-of-systems</a>, <a href="https://publications.waset.org/abstracts/search?q=resilience%20optimization%20model" title=" resilience optimization model"> resilience optimization model</a>, <a href="https://publications.waset.org/abstracts/search?q=recovery%20optimization%20method" title=" recovery optimization method"> recovery optimization method</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20reinforcement%20learning" title=" deep reinforcement learning"> deep reinforcement learning</a>, <a href="https://publications.waset.org/abstracts/search?q=certainty%20and%20uncertainty" title=" certainty and uncertainty"> certainty and uncertainty</a> </p> <a href="https://publications.waset.org/abstracts/193327/enhancing-the-resilience-of-combat-system-of-systems-under-certainty-and-uncertainty-two-phase-resilience-optimization-model-and-deep-reinforcement-learning-based-recovery-optimization-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193327.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">16</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">5965</span> Methanol Steam Reforming with Heat Recovery for Hydrogen-Rich Gas Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Horng-Wen%20Wu">Horng-Wen Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi%20Chao"> Yi Chao</a>, <a href="https://publications.waset.org/abstracts/search?q=Rong-Fang%20Horng"> Rong-Fang Horng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study is to develop a methanol steam reformer with a heat recovery zone, which recovers heat from exhaust gas of a diesel engine, and to investigate waste heat recovery ratio at the required reaction temperature. The operation conditions of the reformer are reaction temperature (200 °C, 250 °C, and 300 °C), steam to carbonate (S/C) ratio (0.9, 1.1, and 1.3), and N2 volume flow rate (40 cm3/min, 70 cm3/min, and 100 cm3/min). Finally, the hydrogen concentration, the CO, CO2, and N2 concentrations are measured and recorded to calculate methanol conversion efficiency, hydrogen flow rate, and assisting combustion gas and impeding combustion gas ratio. The heat source of this reformer comes from electric heater and waste heat of exhaust gas from diesel engines. The objective is to recover waste heat from the engine and to make more uniform temperature distribution within the reformer. It is beneficial for the reformer to enhance the methanol conversion efficiency and hydrogen-rich gas production. Experimental results show that the highest hydrogen flow rate exists at N2 of the volume rate 40 cm3/min and reforming reaction temperature of 300 °C and the value is 19.6 l/min. With the electric heater and heat recovery from exhaust gas, the maximum heat recovery ratio is 13.18 % occurring at water-methanol (S/C) ratio of 1.3 and the reforming reaction temperature of 300 °C. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heat%20recovery" title="heat recovery">heat recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen-rich%20production" title=" hydrogen-rich production"> hydrogen-rich production</a>, <a href="https://publications.waset.org/abstracts/search?q=methanol%20steam%20reformer" title=" methanol steam reformer"> methanol steam reformer</a>, <a href="https://publications.waset.org/abstracts/search?q=methanol%20conversion%20efficiency" title=" methanol conversion efficiency"> methanol conversion efficiency</a> </p> <a href="https://publications.waset.org/abstracts/14202/methanol-steam-reforming-with-heat-recovery-for-hydrogen-rich-gas-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14202.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">466</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">5964</span> Dielectric Recovery Characteristics of High Voltage Gas Circuit Breakers Operating with CO₂ Mixture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Peng%20Lu">Peng Lu</a>, <a href="https://publications.waset.org/abstracts/search?q=Branimir%20Radisavljevic"> Branimir Radisavljevic</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20Seeger"> Martin Seeger</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Over"> Daniel Over</a>, <a href="https://publications.waset.org/abstracts/search?q=Torsten%20Votteler"> Torsten Votteler</a>, <a href="https://publications.waset.org/abstracts/search?q=Bernardo%20Galletti"> Bernardo Galletti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> CO₂-based gas mixtures exhibit huge potential as the interruption medium for replacing SF₆ in high voltage switchgears.

It was shown that there are interactions between parameters during pre-treatment. At 80oC, recovery is independent of the contact time while the maximum recovery is obtained in the absence of agitation (0rpm). Increase in agitation speed from 0 rev/min to 1200 rev/min showed a decrease in recovery of approximately 20 percent at 80°C. Recovery with increased time from 15 minutes to 45 minutes is only pronounced at 25°C with approximately 4 percent increase at all agitation speeds. The results from elution recovery are aimed to give insight into the mechanisms of pre-treatment under the combinations of the chosen parameters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gold" title="gold">gold</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=contact%20time" title=" contact time"> contact time</a>, <a href="https://publications.waset.org/abstracts/search?q=agitation%20speed" title=" agitation speed"> agitation speed</a>, <a href="https://publications.waset.org/abstracts/search?q=recovery" title=" recovery"> recovery</a> </p> <a href="https://publications.waset.org/abstracts/20502/the-effect-of-temperature-contact-time-and-agitation-speed-during-pre-treatment-on-elution-of-gold" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20502.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">490</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">5962</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">5961</span> Research on Low interfacial Tension Viscoelastic Fluid Oil Displacement System in Unconventional Reservoir</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Long%20Long%20Chen">Long Long Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Xinwei%20Liao"> Xinwei Liao</a>, <a href="https://publications.waset.org/abstracts/search?q=Shanfa%20Tang"> Shanfa Tang</a>, <a href="https://publications.waset.org/abstracts/search?q=Shaojing%20Jiang"> Shaojing Jiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruijia%20Tang"> Ruijia Tang</a>, <a href="https://publications.waset.org/abstracts/search?q=Rui%20Wang"> Rui Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Shu%20Yun%20Feng"> Shu Yun Feng</a>, <a href="https://publications.waset.org/abstracts/search?q=Si%20Yao%20Wang"> Si Yao Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Unconventional oil reservoirs have the characteristics of strong heterogeneity and poor injectability, and traditional chemical flooding technology is not effective in such reservoirs; polymer flooding in the production of heavy oil reservoirs is difficult to handle produced fluid and easy to block oil wells, etc. Therefore, a viscoelastic fluid flooding system with good adaptability, low interfacial tension, plugging, and diverting capabilities was studied. The viscosity, viscoelasticity, surface/interfacial activity, wettability, emulsification, and oil displacement performance of the anionic Gemini surfactant flooding system were studied, and the adaptability of the system to the reservoir environment was evaluated. The oil displacement effect of the system in low-permeability and high-permeability (heavy oil) reservoirs was investigated, and the mechanism of the system to enhance water flooding recovery was discussed. The results show that the system has temperature resistance and viscosity increasing performance (65℃, 4.12mPa•s), shear resistance and viscoelasticity; at a lower concentration (0.5%), the oil-water interfacial tension can be reduced to ultra-low (10-3mN/m); has good emulsifying ability for heavy oil, and is easy to break demulsification (4.5min); has good adaptability to reservoirs with high salinity (30000mg/L). Oil flooding experiments show that this system can increase the water flooding recovery rate of low-permeability homogeneous and heterogeneous cores by 13% and 15%, respectively, and can increase the water-flooding recovery rate of high-permeability heavy oil reservoirs by 40%. The anionic Gemini surfactant flooding system studied in this paper is a viscoelastic fluid, has good emulsifying and oil washing ability, can effectively improve sweep efficiency, reduce injection pressure, and has broad application in unconventional reservoirs to enhance oil recovery prospect. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oil%20displacement%20system" title="oil displacement system">oil displacement system</a>, <a href="https://publications.waset.org/abstracts/search?q=recovery%20factor" title=" recovery factor"> recovery factor</a>, <a href="https://publications.waset.org/abstracts/search?q=rheology" title=" rheology"> rheology</a>, <a href="https://publications.waset.org/abstracts/search?q=interfacial%20activity" title=" interfacial activity"> interfacial activity</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20adaptability" title=" environmental adaptability"> environmental adaptability</a> </p> <a href="https://publications.waset.org/abstracts/146670/research-on-low-interfacial-tension-viscoelastic-fluid-oil-displacement-system-in-unconventional-reservoir" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146670.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">124</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">5960</span> Energy and Economic Analysis of Heat Recovery from Boiler Exhaust Flue Gas</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kemal%20Comakli">Kemal Comakli</a>, <a href="https://publications.waset.org/abstracts/search?q=Meryem%20Terhan"> Meryem Terhan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the potential of heat recovery from waste flue gas was examined in 60 MW district heating system of a university, and fuel saving was aimed by using the recovered heat in the system as a source again.

This study evaluates the impact of ERAS on anesthesia management in high-risk surgical patients, focusing on opioid-sparing techniques and multimodal analgesia. A retrospective analysis was conducted on patients undergoing major surgeries within an ERAS program, comparing outcomes with a historical cohort receiving standard care. Key metrics included postoperative pain scores, opioid consumption, length of hospital stay, and complication rates. Results indicated that the implementation of ERAS protocols significantly reduced postoperative opioid use by 40% and improved pain management outcomes, with 70% of patients reporting satisfactory pain control on postoperative day one. Additionally, patients in the ERAS group experienced a 30% reduction in length of stay and a 20% decrease in complication rates. These findings underscore the importance of integrating ERAS principles into anesthesia practice, particularly for high-risk patients, to enhance recovery, improve patient satisfaction, and reduce healthcare costs. Future directions include prospective studies to further refine anesthesia techniques within ERAS frameworks and explore their applicability across various surgical specialties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ERAS%20protocols" title="ERAS protocols">ERAS protocols</a>, <a href="https://publications.waset.org/abstracts/search?q=high-risk%20surgical%20patients" title=" high-risk surgical patients"> high-risk surgical patients</a>, <a href="https://publications.waset.org/abstracts/search?q=anesthesia%20management" title=" anesthesia management"> anesthesia management</a>, <a href="https://publications.waset.org/abstracts/search?q=recovery" title=" recovery"> recovery</a> </p> <a href="https://publications.waset.org/abstracts/191856/the-impact-of-enhanced-recovery-after-surgery-eras-protocols-on-anesthesia-management-in-high-risk-surgical-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191856.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">24</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">5958</span> Protecting the Cloud Computing Data Through the Data Backups</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdullah%20Alsaeed">Abdullah Alsaeed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Virtualized computing and cloud computing infrastructures are no longer fuzz or marketing term.

However, SMAs possess some properties like recovery under stress that SMPs lack. SMPs cannot give complete recovery even under a small load. SMPs are initially heated close to their transition temperature (glass transition temperature or the melting temperature). Then force is applied to deform the heated SMP to a specific position. Subsequently, SMP is allowed to cool keeping it deformed. After cooling, SMP gets the temporary shape. This temporary shape can be recovered by heating it again at the same temperature that was given it while heating it initially. As a result, it will recover its original position. SMP can perform unconstrained recovery and constrained recovery, however; under the load, it only recovers partially. In this work, the recovery under the load of an asymmetrical shape memory composite called as CBCM-SMPC has been investigated. It is found that it has the ability to recover under different loads. Under different loads, it shows powerful complete recovery in reference to initial position. This property can be utilized in many applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=shape%20memory" title="shape memory">shape memory</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer%20composite" title=" polymer composite"> polymer composite</a>, <a href="https://publications.waset.org/abstracts/search?q=thermo-mechanical%20testing" title=" thermo-mechanical testing"> thermo-mechanical testing</a>, <a href="https://publications.waset.org/abstracts/search?q=recovery%20under%20load" title=" recovery under load"> recovery under load</a> </p> <a href="https://publications.waset.org/abstracts/74774/the-shape-memory-recovery-properties-under-load-of-a-polymer-composite" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74774.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">439</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">5956</span> Effects of the Different Recovery Durations on Some Physiological Parameters during 3 X 3 Small-Sided Games in Soccer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samet%20Akta%C5%9F">Samet Aktaş</a>, <a href="https://publications.waset.org/abstracts/search?q=Nurtekin%20Erkmen"> Nurtekin Erkmen</a>, <a href="https://publications.waset.org/abstracts/search?q=Faruk%20Guven"> Faruk Guven</a>, <a href="https://publications.waset.org/abstracts/search?q=Halil%20Taskin"> Halil Taskin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aimed to determine the effects of 3 versus 3 small-sided games (SSG) with different recovery times on soma physiological parameters in soccer players. Twelve soccer players from Regional Amateur League volunteered for this study (mean±SD age, 20.50±2.43 years; height, 177.73±4.13 cm; weight, 70.83±8.38 kg). Subjects were performing soccer training for five days per week. The protocol of the study was approved by the local ethic committee in School of Physical Education and Sport, Selcuk University. The subjects were divided into teams with 3 players according to Yo-Yo Intermittent Recovery Test. The field dimension was 26 m wide and 34 m in length. Subjects performed two times in a random order a series of 3 bouts of 3-a-side SSGs with 3 min and 5 min recovery durations. In SSGs, each set were performed with 6 min duration. The percent of maximal heart rate (% HRmax), blood lactate concentration (LA) and Rated Perceived Exertion (RPE) scale points were collected before the SSGs and at the end of each set. Data were analyzed by analysis of variance (ANOVA) with repeated measures. Significant differences were found between %HRmax in before SSG and 1st set, 2nd set, and 3rd set in both SSG with 3 min recovery duration and SSG with 5 min recovery duration (p<0.05). Means of %HRmax in SSG with 3 min recovery duration at both 1st and 2nd sets were significantly higher than SSG with 5 min recovery duration (p<0.05). No significant difference was found between sets of either SSGs in terms of LA (p>0.05). LA in SSG with 3 min recovery duration was higher than SSG with 5 min recovery duration at 2nd sets (p<0.05). RPE in soccer players was not different between SSGs (p>0.05).In conclusion, this study demonstrates that exercise intensity in SSG with 3 min recovery durations is higher than SSG with 5 min recovery durations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=small-sided%20games" title="small-sided games">small-sided games</a>, <a href="https://publications.waset.org/abstracts/search?q=soccer" title=" soccer"> soccer</a>, <a href="https://publications.waset.org/abstracts/search?q=heart%20rate" title=" heart rate"> heart rate</a>, <a href="https://publications.waset.org/abstracts/search?q=lactate" title=" lactate"> lactate</a> </p> <a href="https://publications.waset.org/abstracts/17945/effects-of-the-different-recovery-durations-on-some-physiological-parameters-during-3-x-3-small-sided-games-in-soccer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17945.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">465</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">5955</span> Influence of Measurement System on Negative Bias Temperature Instability Characterization: Fast BTI vs Conventional BTI vs Fast Wafer Level Reliability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vincent%20King%20Soon%20Wong">Vincent King Soon Wong</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong%20Seng%20Ng"> Hong Seng Ng</a>, <a href="https://publications.waset.org/abstracts/search?q=Florinna%20Sim"> Florinna Sim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Negative Bias Temperature Instability (NBTI) is one of the critical degradation mechanisms in semiconductor device reliability that causes shift in the threshold voltage (Vth).

This paper will demonstrate the severity of NBTI recovery as well as one of the effective methods used to mitigate, which is the minimization of measurement system delays. Comparison was done in between two measurement systems that have significant differences in measurement delays to show how NBTI recovery causes result deviations and how fast measurement systems can mitigate NBTI recovery.

Generally, the metal present in wastewater is not biodegradable and can be accumulated in living animals, humans and plant tissue, causing disorder and diseases. The conventional metal recovery methods include chemical, physical and biological methods, but these are chemical and energy intensive. The recent development in microbial fuel cell (MFC) technology provides a new approach for metal recovery; this technology offers a flexible platform for both reduction and oxidation reaction oriented process. The use of MFCs will be a new platform for more efficient and low energy approach for metal recovery from the wastewater.

However, CO₂ is unable to generate the foam/stable foam above its supercritical point (1100 psi, 31°C). These difficulties with CO₂ foam is overcome by adding N₂ in small fraction to enhance the foam generation of CO₂ at supercritical conditions. This study shows how the addition of small quantity of N₂ helps in generating the CO₂ foam and performance of the CO₂/N₂ mixture foam in enhanced oil recovery. To investigate the performance of CO₂/N₂ foam, core-flooding experiments were conducted at elevated pressure and temperature condition (higher than supercritical CO₂ - 50°C and 1500 psi) in sandstone cores. Fluorosurfactant (FS-51) was used as a foaming agent, and n-decane was used as model oil in all the experiments. The selection of foam quality and N₂ fraction was optimized based on foam generation and stability tests. Every gas or foam flooding was preceded by seawater injection to simulate the behavior in the reservoir. The results from the core-flood experiments showed that the CO₂ and CO₂/N₂ foam flooding recovered an additional 34-40% of Original Initial Oil in Place (OIIP) indicating that foam flooding succeeded in producing more oil than pure CO₂ gas injection processes. Additionally, the performance CO₂/N₂ foam injection was better than CO₂ foam injection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82%2FN%E2%82%82%20foam" title="CO₂/N₂ foam">CO₂/N₂ foam</a>, <a href="https://publications.waset.org/abstracts/search?q=enhanced%20oil%20recovery%20%28EOR%29" title=" enhanced oil recovery (EOR)"> enhanced oil recovery (EOR)</a>, <a href="https://publications.waset.org/abstracts/search?q=supercritical%20CO%E2%82%82" title=" supercritical CO₂"> supercritical CO₂</a>, <a href="https://publications.waset.org/abstracts/search?q=sweep%20efficiency" title=" sweep efficiency"> sweep efficiency</a> </p> <a href="https://publications.waset.org/abstracts/71419/performance-of-co2n2-foam-in-enhanced-oil-recovery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71419.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">276</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">5952</span> Metrics and Methods for Improving Resilience in Agribusiness Supply Chains</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Golnar%20Behzadi">Golnar Behzadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20O%27Sullivan"> Michael O'Sullivan</a>, <a href="https://publications.waset.org/abstracts/search?q=Tava%20Olsen"> Tava Olsen</a>, <a href="https://publications.waset.org/abstracts/search?q=Abraham%20Zhang"> Abraham Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> By definition, increasing supply chain resilience improves the supply chain’s ability to return to normal, or to an even more desirable situation, quickly and efficiently after being hit by a disruption. This is especially critical in agribusiness supply chains where the products are perishable and have a short life-cycle. In this paper, we propose a resilience metric to capture and improve the recovery process in terms of both performance and time, of an agribusiness supply chain following either supply or demand-side disruption. We build a model that determines optimal supply chain recovery planning decisions and selects the best resilient strategies that minimize the loss of profit during the recovery time window. The model is formulated as a two-stage stochastic mixed-integer linear programming problem and solved with a branch-and-cut algorithm. The results show that the optimal recovery schedule is highly dependent on the duration of the time-window allowed for recovery. In addition, the profit loss during recovery is reduced by utilizing the proposed resilient actions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agribusiness%20supply%20chain" title="agribusiness supply chain">agribusiness supply chain</a>, <a href="https://publications.waset.org/abstracts/search?q=recovery" title=" recovery"> recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=resilience%20metric" title=" resilience metric"> resilience metric</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20management" title=" risk management"> risk management</a> </p> <a href="https://publications.waset.org/abstracts/67437/metrics-and-methods-for-improving-resilience-in-agribusiness-supply-chains" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67437.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">397</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">5951</span> Oil Recovery Study by Low Temperature Carbon Dioxide Injection in High-Pressure High-Temperature Micromodels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zakaria%20Hamdi">Zakaria Hamdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariyamni%20Awang"> Mariyamni Awang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For the past decades, CO<sub>2</sub> flooding has been used as a successful method for enhanced oil recovery (EOR). However, high mobility ratio and fingering effect are considered as important drawbacka of this process. Low temperature injection of CO<sub>2</sub> into high temperature reservoirs may improve the oil recovery, but simulating multiphase flow in the non-isothermal medium is difficult, and commercial simulators are very unstable in these conditions. Furthermore, to best of authors’ knowledge, no experimental work was done to verify the results of the simulations and to understand the pore-scale process. In this paper, we present results of investigations on injection of low temperature CO<sub>2</sub> into a high-pressure high-temperature micromodel with injection temperature range from 34 to 75 °F. Effect of temperature and saturation changes of different fluids are measured in each case. The results prove the proposed method. The injection of CO<sub>2</sub> at low temperatures increased the oil recovery in high temperature reservoirs significantly. Also, CO<sub>2</sub> rich phases available in the high temperature system can affect the oil recovery through the better sweep of the oil which is initially caused by penetration of LCO<sub>2</sub> inside the system. Furthermore, no unfavorable effect was detected using this method. Low temperature CO<sub>2</sub> is proposed to be used as early as secondary recovery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=enhanced%20oil%20recovery" title="enhanced oil recovery">enhanced oil recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82%20flooding" title=" CO₂ flooding"> CO₂ flooding</a>, <a href="https://publications.waset.org/abstracts/search?q=micromodel%20studies" title=" micromodel studies"> micromodel studies</a>, <a href="https://publications.waset.org/abstracts/search?q=miscible%20flooding" title=" miscible flooding"> miscible flooding</a> </p> <a href="https://publications.waset.org/abstracts/71727/oil-recovery-study-by-low-temperature-carbon-dioxide-injection-in-high-pressure-high-temperature-micromodels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71727.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">352</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">5950</span> Surfactant Improved Heavy Oil Recovery in Sandstone Reservoirs by Wettability Alteration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rabia%20Hunky">Rabia Hunky</a>, <a href="https://publications.waset.org/abstracts/search?q=Hayat%20Kalifa"> Hayat Kalifa</a>, <a href="https://publications.waset.org/abstracts/search?q=Bai"> Bai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The wettability of carbonate reservoirs has been widely recognized as an important parameter in oil recovery by flooding technology. Many surfactants have been studied for this application. However, the importance of wettability alteration in sandstone reservoirs by surfactant has been poorly studied. In this paper, our recent study of the relationship between rock surface wettability and cumulative oil recovery for sandstone cores is reported. In our research, it has been found there is a good agreement between the wettability and oil recovery. Nonionic surfactants, Tomadol® 25-12 and Tomadol® 45-13, are very effective in wettability alteration of sandstone core surface from highly oil-wet conditions to water-wet conditions. By spontaneous imbibition test, Interfacial tension, and contact angle measurement these two surfactants exhibit the highest recovery of the synthetic oil made with heavy oil. Based on these experimental results, we can further conclude that the contact angle measurement and imbibition test can be used as rapid screening tools to identify better EOR surfactants to increase heavy oil recovery from sandstone reservoirs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EOR" title="EOR">EOR</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20gas" title=" oil gas"> oil gas</a>, <a href="https://publications.waset.org/abstracts/search?q=IOR" title=" IOR"> IOR</a>, <a href="https://publications.waset.org/abstracts/search?q=WC" title=" WC"> WC</a>, <a href="https://publications.waset.org/abstracts/search?q=IF" title=" IF"> IF</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20and%20gas" title=" oil and gas"> oil and gas</a> </p> <a href="https://publications.waset.org/abstracts/151355/surfactant-improved-heavy-oil-recovery-in-sandstone-reservoirs-by-wettability-alteration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151355.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">103</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">5949</span> Simulation of Utility Accrual Scheduling and Recovery Algorithm in Multiprocessor Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Idawaty">A.

This algorithm implements the Backward Recovery (BR) mechanism as a fault recovery solution under the existing Time/Utility Function/ Utility Accrual (TUF/UA) scheduling domain for multiprocessor environment. The BR mechanism attempts to take the faulty tasks back to its initial safe state and then proceeds to re-execute the affected section of the faulty tasks to enable recovery. Considering that faults may occur in the components of any system; a fault tolerance system that can nullify the erroneous effect is necessary to be developed. Current TUF/UA scheduling algorithm uses the abortion recovery mechanism and it simply aborts the erroneous task as their fault recovery solution. None of the existing algorithm in TUF/UA scheduling domain in multiprocessor scheduling environment have considered the transient fault and implement the BR mechanism as a fault recovery mechanism to nullify the erroneous effect and solve the recovery problem in this domain. The developed BR_GPUAS simulator has derived the set of parameter, events and performance metrics according to a detailed analysis of the base model. Simulation results revealed that BR_GPUAS algorithm can saved almost 20-30% of the accumulated utilities making it reliable and efficient for the real-time application in the multiprocessor scheduling environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=real-time%20system%20%28RTS%29" title="real-time system (RTS)">real-time system (RTS)</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20utility%20function%2F%20utility%20accrual%20%28TUF%2FUA%29%20scheduling" title=" time utility function/ utility accrual (TUF/UA) scheduling"> time utility function/ utility accrual (TUF/UA) scheduling</a>, <a href="https://publications.waset.org/abstracts/search?q=backward%20recovery%20mechanism" title=" backward recovery mechanism"> backward recovery mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=multiprocessor" title=" multiprocessor"> multiprocessor</a>, <a href="https://publications.waset.org/abstracts/search?q=discrete%20event%20simulation%20%28DES%29" title=" discrete event simulation (DES)"> discrete event simulation (DES)</a> </p> <a href="https://publications.waset.org/abstracts/52774/simulation-of-utility-accrual-scheduling-and-recovery-algorithm-in-multiprocessor-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52774.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">306</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">5948</span> Evaluating the effects of Gas Injection on Enhanced Gas-Condensate Recovery and Reservoir Pressure Maintenance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20S.%20Alavi">F.

Some experimental data were used to tune the Peng-Robinson equation of state for this case. Different scenarios of gas injection at current reservoir pressure and at abandonment reservoir pressure had been considered with different gas compositions. Methane, carbon dioxide, nitrogen and two other gases with specified compositions were considered as potential gases for injection. According to the obtained results, nitrogen leads to highest pressure maintenance in the reservoir but methane results in highest condensate recovery among the selected injection gases. At low injection rates, condensate recovery percent is strongly affected by gas injection rate but this dependency shifts to zero at high injection rates. Condensate recovery is higher in all cases of injection at current reservoir pressure than injection at abandonment pressure. Using a constant injection rate, increasing the production well bottom hole pressure results in increasing the condensate recovery percent and time of gas breakthrough. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gas-condensate%20reservoir" title="gas-condensate reservoir">gas-condensate reservoir</a>, <a href="https://publications.waset.org/abstracts/search?q=case-study" title=" case-study"> case-study</a>, <a href="https://publications.waset.org/abstracts/search?q=compositional%20modelling" title=" compositional modelling"> compositional modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=enhanced%20condensate%20recovery" title=" enhanced condensate recovery"> enhanced condensate recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20injection" title=" gas injection"> gas injection</a> </p> <a href="https://publications.waset.org/abstracts/153670/evaluating-the-effects-of-gas-injection-on-enhanced-gas-condensate-recovery-and-reservoir-pressure-maintenance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153670.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">195</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">5947</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
