Technique” is well documented. However, Patch Clamp Technique is very expensive and hence hinders research in developing countries. In this paper, detection, processing and recording of ultra low current from induced cells by using transimpedence amplifier is described. The sensitivity of the proposed amplifier is in the range of femto amperes (fA). Capacitive-feedback is used with active load to obtain a 20MΩ transimpedance gain. The challenging task in designing includes achieving adequate performance in gain, noise immunity and stability. The circuit designed by the authors was able to measure current in the rangeof 300fA to 100pA. Adequate performance shown by the amplifier with different input current and outcome result was found to be within the acceptable error range. Results were recorded using LabVIEW 8.5®for further research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drug%20discovery" title="drug discovery">drug discovery</a>, <a href="https://publications.waset.org/abstracts/search?q=ionic%20current" title=" ionic current"> ionic current</a>, <a href="https://publications.waset.org/abstracts/search?q=operational%20amplifier" title=" operational amplifier"> operational amplifier</a>, <a href="https://publications.waset.org/abstracts/search?q=patch%20clamp" title=" patch clamp"> patch clamp</a> </p> <a href="https://publications.waset.org/abstracts/28042/indigenous-patch-clamp-technique-design-of-highly-sensitive-amplifier-circuit-for-measuring-and-monitoring-of-real-time-ultra-low-ionic-current-through-cellular-gates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28042.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">519</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">59</span> Experimental Investigation and Constitutive Modeling of Volume Strain under Uniaxial Strain Rate Jump Test in HDPE</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rida%20B.%20Arieby">Rida B.

The dependency of the true stress and specially the variation of volume strain have been investigated, the volume strain due to the phenomena of damage was determined in real time during the tests by an optical extensometer called Videotraction. A modified constitutive equations, including strain rate and damage effects, are proposed, such a model is based on a non-equilibrium thermodynamic approach called (DNLR). The ability of the model to predict the complex nonlinear response of this polymer is examined by comparing the model simulation with the available experimental data, which demonstrate that this model can represent the deformation behavior of the polymer reasonably well. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=strain%20rate%20jump%20tests" title="strain rate jump tests">strain rate jump tests</a>, <a href="https://publications.waset.org/abstracts/search?q=volume%20strain" title=" volume strain"> volume strain</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20density%20polyethylene" title=" high density polyethylene"> high density polyethylene</a>, <a href="https://publications.waset.org/abstracts/search?q=large%20strain" title=" large strain"> large strain</a>, <a href="https://publications.waset.org/abstracts/search?q=thermodynamics%20approach" title=" thermodynamics approach"> thermodynamics approach</a> </p> <a href="https://publications.waset.org/abstracts/6857/experimental-investigation-and-constitutive-modeling-of-volume-strain-under-uniaxial-strain-rate-jump-test-in-hdpe" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6857.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">258</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">58</span> A Prospective Evaluation of Thermal Radiation Effects on Magneto-Hydrodynamic Transport of a Nanofluid Traversing a Spongy Medium</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Azad%20Hussain">Azad Hussain</a>, <a href="https://publications.waset.org/abstracts/search?q=Shoaib%20Ali"> Shoaib Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Y.%20Malik"> M.

Here, viscosity is taken as function of temperature. Energy equation is deliberated in the existence of viscous dissipation. The mathematical terminologies of nano concentration, velocity and temperature are first cast into dimensionless expressions via suitable conversions and then solved by using Shooting technique to obtain the numerical solutions. Graphs has been plotted to check the convergence of constructed solutions. At the end, the influence of effective parameters on nanoparticle concentration, velocity and temperature fields are also deliberated in a comprehensive way. Moreover, the physical measures of engineering importance such as the Sherwood number, Skin friction and Nusselt number are also calculated. It is perceived that the thermal radiation enhances the temperature for both Vogel's and Reynolds' models but the normal stress parameter causes a reduction in temperature profile. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MHD%20flow" title="MHD flow">MHD flow</a>, <a href="https://publications.waset.org/abstracts/search?q=differential%20type%20nanofluid" title=" differential type nanofluid"> differential type nanofluid</a>, <a href="https://publications.waset.org/abstracts/search?q=Porous%20medium" title=" Porous medium"> Porous medium</a>, <a href="https://publications.waset.org/abstracts/search?q=variable%20viscosity" title=" variable viscosity"> variable viscosity</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20radiation" title=" thermal radiation"> thermal radiation</a> </p> <a href="https://publications.waset.org/abstracts/89385/a-prospective-evaluation-of-thermal-radiation-effects-on-magneto-hydrodynamic-transport-of-a-nanofluid-traversing-a-spongy-medium" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89385.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">243</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">57</span> Simulation and Characterization of Organic Light Emitting Diodes and Organic Photovoltaics Using Physics Based Tool</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20A.%20Shahul%20Hameed">T.

In addition to hardware cost reduction and data center trail, the disaster recovery plan can ensure system uptime and to meet objectives of high availability, recovery time, recovery point, server provisioning, and quality of services. 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. This recovery model would make disaster recovery a lot easier, faster, and less error prone. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autonomous%20intelligence" title="autonomous intelligence">autonomous intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=disaster%20recovery" title=" disaster recovery"> disaster recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=cloud%20computing" title=" cloud computing"> cloud computing</a>, <a href="https://publications.waset.org/abstracts/search?q=server%20virtualization" title=" server virtualization"> server virtualization</a> </p> <a href="https://publications.waset.org/abstracts/129654/autonomic-recovery-plan-with-server-virtualization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129654.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">54</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.

It does not remain deposited in a place for long, as it is easily resuspended back into the atmosphere. Street dust is a complex mixture derived from different sources: Deposited dust, traffic, tire, and brake wear, construction and demolition processes. The present study aims to evaluate the elementals ”iron, calcium, lead, cadmium, nickel, silicon, and selenium” and microbial “bacteria and fungi” contents associated street dust at the holy mosque areas. The street dust was collected by sweeping an arera~1m2 along the both sides of the road. The particles with diameter ≤ 1.7 µm constitued the highest percentages of the total particulate ≤45 µm. Moreover, The crustal species: iron and calcium were found in the highest concentrations, and proof that demolition and constricution were the main source of street dust. Also, the low biodiversity of microorganisms is attributed to severe weather conditions and characteristics of the arid environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dust" title="dust">dust</a>, <a href="https://publications.waset.org/abstracts/search?q=microbial" title=" microbial"> microbial</a>, <a href="https://publications.waset.org/abstracts/search?q=environment" title=" environment"> environment</a>, <a href="https://publications.waset.org/abstracts/search?q=street" title=" street"> street</a> </p> <a href="https://publications.waset.org/abstracts/30427/the-effect-of-street-dust-on-urban-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30427.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">553</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">50</span> Polymorphic Positions, Haplotypes, and Mutations Detected In The Mitochonderial DNA Coding Region By Sanger Sequence Technique </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Imad%20H.%20Hameed">Imad H.

Amongst them, Farsetia aegyptia Turra and Farsetia longisiliqua Decne. are two common species characteristic to the Egyptian flora. The present study considers the first characterization of the chemical constituents of F. longisiliqua, aiming to compare with those identified from the medicinal species (F. aegyptia). Additionally, the chemosystematic relationships between the two studied species were evaluated and highlight the medicinal importance for F. longisiliqua. The chemical profiling of their aqueous methanol extracts were carried out using the LC-ESI-MS technique and afforded 54 compounds belonging to different chemical groups. Flavonoids are the major constituents and are represented by 32 compounds (two C-glycosyl flavone, four flavones, and 26 flavonols). Their structural variations and common constituents confirmed the chemosystematic significance of the two species. Moreover, the flavonoid profiles showed major common constituents between the two investigated species, which predicted the medicinal importance of F. longisiliqua. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brassicaceae" title="brassicaceae">brassicaceae</a>, <a href="https://publications.waset.org/abstracts/search?q=chemosystematics" title=" chemosystematics"> chemosystematics</a>, <a href="https://publications.waset.org/abstracts/search?q=farsetia" title=" farsetia"> farsetia</a>, <a href="https://publications.waset.org/abstracts/search?q=flavonoids" title=" flavonoids"> flavonoids</a>, <a href="https://publications.waset.org/abstracts/search?q=glucosinolates" title=" glucosinolates"> glucosinolates</a>, <a href="https://publications.waset.org/abstracts/search?q=LC-ESI-MS" title=" LC-ESI-MS"> LC-ESI-MS</a> </p> <a href="https://publications.waset.org/abstracts/131531/chemical-profiling-of-farsetia-aegyptia-turra-and-farsetia-longisiliqua-decne-and-their-chemosystematic-significance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131531.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">209</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">46</span> A Simplified, Low-Cost Mechanical Design for an Automated Motorized Mechanism to Clean Large Diameter Pipes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Imad%20Khan">Imad Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Imran%20Shafi"> Imran Shafi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarmad%20Farooq"> Sarmad Farooq</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Large diameter pipes, barrels, tubes, and ducts are used in a variety of applications covering civil and defense-related technologies. This may include heating/cooling networks, sign poles, bracing, casing, and artillery and tank gun barrels. These large diameter assemblies require regular inspection and cleaning to increase their life and reduce replacement costs. This paper describes the design, development, and testing results of an efficient yet simplified, low maintenance mechanical design controlled with minimal essential electronics using an electric motor for a non-technical staff. The proposed solution provides a simplified user interface and an automated cleaning mechanism that requires a single user to optimally clean pipes and barrels in the range of 105 mm to 203 mm caliber. The proposed system employs linear motion of specially designed brush along the barrel using a chain of specific strength and a pulley anchor attached to both ends of the barrel. A specially designed and manufactured gearbox is coupled with an AC motor to allow movement of contact brush with high torque to allow efficient cleaning. A suitably powered AC motor is fixed to the front adapter mounted on the muzzle side whereas the rear adapter has a pulley-based anchor mounted towards the breach block in case of a gun barrel. A mix of soft nylon and hard copper bristles-based large surface brush is connected through a strong steel chain to motor and anchor pulley. The system is equipped with limit switches to auto switch the direction when one end is reached on its operation. The testing results based on carefully established performance indicators indicate the superiority of the proposed user-friendly cleaning mechanism vis-à-vis its life cycle cost. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pipe%20cleaning%20mechanism" title="pipe cleaning mechanism">pipe cleaning mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=limiting%20switch" title=" limiting switch"> limiting switch</a>, <a href="https://publications.waset.org/abstracts/search?q=pipe%20cleaning%20robot" title=" pipe cleaning robot"> pipe cleaning robot</a>, <a href="https://publications.waset.org/abstracts/search?q=large%20pipes" title=" large pipes"> large pipes</a> </p> <a href="https://publications.waset.org/abstracts/150969/a-simplified-low-cost-mechanical-design-for-an-automated-motorized-mechanism-to-clean-large-diameter-pipes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150969.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">110</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">45</span> Ubiquitous Collaborative Mobile Learning (UCML): A Flexible Instructional Design Model for Social Learning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hameed%20Olalekan%20Bolaji">Hameed Olalekan Bolaji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The digital natives are driving the trends of literacy in the use of electronic devices for learning purposes.

There is no engineering method known available to ameliorate the dispersed pollutants. The only suitable approach is the ecological method of constructing green belts in and around the pollution sources. Air pollution in Muscat, Oman is a serious concern due to ever increasing vehicles on roads. Identifying the air pollution tolerance levels of species is important for implementing pollution control strategies in the urban areas of Muscat. Hence, in the present study, Air Pollution Tolerance Index (APTI) for ten avenue tree species was evaluated by analyzing four bio-chemical parameters, plus their Anticipated Performance Index (API) in field conditions. Based on the two indices, <em>Ficus benghalensis</em> was the most suitable one with the highest performance score. <em>Conocarpus erectuse, Phoenix dactylifera</em>, and <em>Pithcellobium dulce </em>were found to be good performers and are recommended for extensive planting. <em>Azadirachta indica</em> which is preferred for its dense canopy is qualified in the moderate category. The rest of the tree species expressed lower API score of less than 51, hence cannot be considered as suitable species for pollution mitigation plantation projects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=air%20pollution%20tolerance%20index%20%28APTI%29" title="air pollution tolerance index (APTI)">air pollution tolerance index (APTI)</a>, <a href="https://publications.waset.org/abstracts/search?q=avenue%20tree%20species" title=" avenue tree species"> avenue tree species</a>, <a href="https://publications.waset.org/abstracts/search?q=bio-chemical%20parameters" title=" bio-chemical parameters"> bio-chemical parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=muscat" title=" muscat"> muscat</a> </p> <a href="https://publications.waset.org/abstracts/56371/trees-for-air-pollution-tolerance-to-develop-green-belts-as-an-ecological-mitigation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56371.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">284</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">43</span> Functionality Based Composition of Web Services to Attain Maximum Quality of Service</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Mohemmed%20Sha%20Mohamed%20Kunju">M.

A single web service with limited functionality is inadequate to execute a specific task with series of action. So, it is very much required to combine multiple web services with different functionalities to reach the target. Also, it will become more and more challenging, when these services are from different providers with identical functionalities and varying QoS, so while composing the web services, the overall QoS is considered to be the major factor. Also, it is not true that the expected QoS is always attained when the task is completed. A single web service in the composed chain may affect the overall performance of the task. So care should be taken in different aspects such as functionality of the service, while composition. Dynamic and automatic service composition is one of the main option available. But to achieve the actual functionality of the task, quality of the individual web services are also important. Normally the QoS of the individual service can be evaluated by using the non-functional parameters such as response time, throughput, reliability, availability, etc. At the same time, the QoS is not needed to be at the same level for all the composed services. So this paper proposes a framework that allows composing the services in terms of QoS by setting the appropriate weight to the non-functional parameters of each individual web service involved in the task. Experimental results show that the importance given to the non-functional parameter while composition will definitely improve the performance of the web services. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composition" title="composition">composition</a>, <a href="https://publications.waset.org/abstracts/search?q=non-functional%20parameters" title=" non-functional parameters"> non-functional parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20service" title=" quality of service"> quality of service</a>, <a href="https://publications.waset.org/abstracts/search?q=web%20service" title=" web service"> web service</a> </p> <a href="https://publications.waset.org/abstracts/57664/functionality-based-composition-of-web-services-to-attain-maximum-quality-of-service" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57664.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">333</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">42</span> Hopes of out of School Children with Disabilities for Educational Inclusion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Afaf%20Manzoor">Afaf Manzoor</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Hameed"> Abdul Hameed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hopes to attend school is the most effective means to overcome the burden of disability and become a self-reliant, productive citizen. The objectives of the study were to develop a valid and reliable scale to measure hopes of out of school children with disabilities and find an association between hopes and various demographic factors such as type of disability, gender, socio-economic status, and locale, etc. Child Hope theory by Snyder (2003) was used as a framework to develop a measure for the hopes of children. According to this theory, hope is defined as a set of cognition that includes self- perception which establish routes to achieve desired goals (pathways) and motivation for achieving the goals (agency). By applying this theory, inclusion hope scale was developed and validated. The data were collected from 361 out of school children with disabilities living in three districts (Lahore, Sheikupura, Kasur) of Lahore Division by using the cluster sampling technique. Findings of the study indicated that children with intellectual challenges were more hopeless as compared to other types of disabilities. Similarly, children living in urban areas have better hopes for inclusion in school. However, no gender disparity was found in terms of being hopeful to attend schools. The study also includes recommendations to improve hopes for educational inclusion among out of school children with disabilities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=out%20of%20school%20children" title="out of school children">out of school children</a>, <a href="https://publications.waset.org/abstracts/search?q=disability" title=" disability"> disability</a>, <a href="https://publications.waset.org/abstracts/search?q=hopes" title=" hopes"> hopes</a>, <a href="https://publications.waset.org/abstracts/search?q=inclusion" title=" inclusion"> inclusion</a> </p> <a href="https://publications.waset.org/abstracts/102023/hopes-of-out-of-school-children-with-disabilities-for-educational-inclusion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102023.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">173</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">41</span> A Unified Constitutive Model for the Thermoplastic/Elastomeric-Like Cyclic Response of Polyethylene with Different Crystal Contents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Baqqal">A.

Experimental observations on a high-density polyethylene with 72% crystal content and an ultralow density polyethylene with 15% crystal content are reported. The cyclic stretching does appear a thermoplastic-like response for high crystallinity and an elastomeric-like response for low crystallinity, both characterized by a stress-softening, a hysteresis and a residual strain, whose amount depends on the crystallinity and the applied strain. Based on the experimental observations, a unified viscoelastic-viscoplastic constitutive model capturing the polyethylene cyclic response features is proposed. A two-phase representation of the polyethylene microstructure allows taking into consideration the effective contribution of the crystalline and amorphous phases to the intermolecular resistance to deformation which is coupled, to capture the strain hardening, to a resistance to molecular orientation. The polyethylene cyclic response features are captured by introducing evolution laws for the model parameters affected by the microstructure alteration due to the cyclic stretching. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cyclic%20loading%20unloading" title="cyclic loading unloading">cyclic loading unloading</a>, <a href="https://publications.waset.org/abstracts/search?q=polyethylene" title=" polyethylene"> polyethylene</a>, <a href="https://publications.waset.org/abstracts/search?q=semi-crystalline%20polymer" title=" semi-crystalline polymer"> semi-crystalline polymer</a>, <a href="https://publications.waset.org/abstracts/search?q=viscoelastic-viscoplastic%20constitutive%20model" title=" viscoelastic-viscoplastic constitutive model"> viscoelastic-viscoplastic constitutive model</a> </p> <a href="https://publications.waset.org/abstracts/80248/a-unified-constitutive-model-for-the-thermoplasticelastomeric-like-cyclic-response-of-polyethylene-with-different-crystal-contents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80248.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">224</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">40</span> Online Handwritten Character Recognition for South Indian Scripts Using Support Vector Machines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Steffy%20Maria%20Joseph">Steffy Maria Joseph</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdu%20Rahiman%20V"> Abdu Rahiman V</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Hameed%20K.%20M."> Abdul Hameed K.

The classification success rate of current techniques decreases when the dataset involves similarity and complexity in stroke styles, number of strokes and stroke characteristics variations. Malayalam is a complex south indian language spoken by about 35 million people especially in Kerala and Lakshadweep islands. In this paper, we consider the significant feature extraction for the similar stroke styles of Malayalam. This extracted feature set are suitable for the recognition of other handwritten south indian languages like Tamil, Telugu and Kannada. A classification scheme based on support vector machines (SVM) is proposed to improve the accuracy in classification and recognition of online malayalam handwritten characters. SVM Classifiers are the best for real world applications. The contribution of various features towards the accuracy in recognition is analysed. Performance for different kernels of SVM are also studied. A graphical user interface has developed for reading and displaying the character. Different writing styles are taken for each of the 44 alphabets. Various features are extracted and used for classification after the preprocessing of input data samples. Highest recognition accuracy of 97% is obtained experimentally at the best feature combination with polynomial kernel in SVM. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SVM" title="SVM">SVM</a>, <a href="https://publications.waset.org/abstracts/search?q=matlab" title=" matlab"> matlab</a>, <a href="https://publications.waset.org/abstracts/search?q=malayalam" title=" malayalam"> malayalam</a>, <a href="https://publications.waset.org/abstracts/search?q=South%20Indian%20scripts" title=" South Indian scripts"> South Indian scripts</a>, <a href="https://publications.waset.org/abstracts/search?q=onlinehandwritten%20character%20recognition" title=" onlinehandwritten character recognition"> onlinehandwritten character recognition</a> </p> <a href="https://publications.waset.org/abstracts/30826/online-handwritten-character-recognition-for-south-indian-scripts-using-support-vector-machines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30826.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">574</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">39</span> Power System Stability Enhancement Using Self Tuning Fuzzy PI Controller for TCSC</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salman%20Hameed">Salman Hameed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a self-tuning fuzzy PI controller (STFPIC) is proposed for thyristor controlled series capacitor (TCSC) to improve power system dynamic performance. In a STFPIC controller, the output scaling factor is adjusted on-line by an updating factor (α). The value of α is determined from a fuzzy rule-base defined on error (e) and change of error (Δe) of the controlled variable. The proposed self-tuning controller is designed using a very simple control rule-base and the most natural and unbiased membership functions (MFs) (symmetric triangles with equal base and 50% overlap with neighboring MFs). The comparative performances of the proposed STFPIC and the standard fuzzy PI controller (FPIC) have been investigated on a multi-machine power system (namely, 4 machine two area system) through detailed non-linear simulation studies using MATLAB/SIMULINK. From the simulation studies it has been found out that for damping oscillations, the performance of the proposed STFPIC is better than that obtained by the standard FPIC. Moreover, the proposed STFPIC as well as the FPIC have been found to be quite effective in damping oscillations over a wide range of operating conditions and are quite effective in enhancing the power carrying capability of the power system significantly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title="genetic algorithm">genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20system%20stability" title=" power system stability"> power system stability</a>, <a href="https://publications.waset.org/abstracts/search?q=self-tuning%20fuzzy%20controller" title=" self-tuning fuzzy controller"> self-tuning fuzzy controller</a>, <a href="https://publications.waset.org/abstracts/search?q=thyristor%20controlled%20series%20capacitor" title=" thyristor controlled series capacitor"> thyristor controlled series capacitor</a> </p> <a href="https://publications.waset.org/abstracts/7935/power-system-stability-enhancement-using-self-tuning-fuzzy-pi-controller-for-tcsc" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7935.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">423</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">38</span> Pectin Degrading Enzyme: Entrapment of Pectinase Using Different Synthetic and Non-Synthetic Polymers for Continuous Degradation of Pectin Polymer </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Haneef%20Ur%20Rehman">Haneef Ur Rehman</a>, <a href="https://publications.waset.org/abstracts/search?q=Afsheen%20Aman"> Afsheen Aman</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Hameed%20Baloch"> Abdul Hameed Baloch</a>, <a href="https://publications.waset.org/abstracts/search?q=Shah%20Ali%20Ul%20Qader"> Shah Ali Ul Qader</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pectinase is a heterogeneous group of enzymes that catalyze the hydrolysis of pectin substances and widely has been used in food and textile industries. In current study, pectinase from B. licheniformis KIBGE-IB21 was immobilized within different polymers (calcium alginate beads, polyacrylamide gel and agar-agar matrix) to enhance its catalytic properties. Polyacrylamide gel was found to be most promising one and gave maximum (89%) immobilization yield. While less immobilization yield was observed in case of calcium alginate beads that only retained 46 % activity. The reaction time for maximum pectinolytic activity was increased from 5.0 to 10 minutes after immobilization. The temperature of pectinase for maximum enzyme activity was increased from 45 °C to 50 °C and 55 °C when it was immobilized within agar-agar and calcium alginate beads, respectively. The optimum pH of pectinase didn’t alter when it was immobilized within polyacrylamide gel and calcium alginate beads, but in case of agar-agar it was changed from pH 10 to pH 9.0. Thermal stability of pectinase was improved after immobilization and immobilized pectinase showed higher toleration against different temperatures as compared to free enzyme. It can be concluded that the entrapment is a simple, single step and promising procedure to immobilized pectinase within different synthetic and non-synthetic polymers and enhanced its catalytic properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pectinase" title="pectinase">pectinase</a>, <a href="https://publications.waset.org/abstracts/search?q=characterization%20immobilization" title=" characterization immobilization"> characterization immobilization</a>, <a href="https://publications.waset.org/abstracts/search?q=polyacrylamide" title=" polyacrylamide"> polyacrylamide</a>, <a href="https://publications.waset.org/abstracts/search?q=agar-agar" title=" agar-agar"> agar-agar</a>, <a href="https://publications.waset.org/abstracts/search?q=calcium%20alginate%20beads" title=" calcium alginate beads"> calcium alginate beads</a> </p> <a href="https://publications.waset.org/abstracts/21905/pectin-degrading-enzyme-entrapment-of-pectinase-using-different-synthetic-and-non-synthetic-polymers-for-continuous-degradation-of-pectin-polymer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21905.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">606</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">37</span> Multi-Dimensional Energy Resource Evaluation in Climate Change beyond the 21st Century</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hameed%20Alshammari">Hameed Alshammari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The decarbonisation of the energy sector beyond the 21ˢᵗ century is akin to establishing morally responsible mechanisms that can propagate sustainable livelihoods (Denina et al., 2021). It implies that Kuwait undertakes a re-evaluation of energy generation gaps so as to tap the potential to reduce overreliance on fossil fuel (Si et al., 2020) and align with global views on sustainable energy generation and consumption.(Herrero, Pineda, Villar, & Zambrano, 2020). Without the economic pressure to switch to alternative sources of energy, Kuwait requires a multi-dimensional analysis the energy policies andsources of energy other than fossil fuels (Alsaad, 2021).Currently, Kuwait has an energy system that is highly skewed towards fossil fuels (Alsaad, 2021); hence, the reliance on burning fossil fuels forms part of the core elements of the general inefficient energy systems that have negative consequences to global environmental and economic systems (Kang et al., 2020). This paper undertakes a detailed literature review on factors needed for the development of a framework for the multi-dimensional energy resource analysis in Kuwait. The framework aims aligning the current energy policies in Kuwait with the global decarbonisation drive, to promote sustainable energy strategies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=decarbonisation" title="decarbonisation">decarbonisation</a>, <a href="https://publications.waset.org/abstracts/search?q=energy" title=" energy"> energy</a>, <a href="https://publications.waset.org/abstracts/search?q=fossil%20fuels" title=" fossil fuels"> fossil fuels</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-dimensional%20analysis" title=" multi-dimensional analysis"> multi-dimensional analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/149672/multi-dimensional-energy-resource-evaluation-in-climate-change-beyond-the-21st-century" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149672.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">86</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">36</span> Lean Construction Techniques in Construction Projects of Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aftab%20Hameed%20Memon">Aftab Hameed Memon</a>, <a href="https://publications.waset.org/abstracts/search?q=Shadab%20Noor"> Shadab Noor</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Akram%20Akhund"> Muhammad Akram Akhund</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lean construction is a philosophy adopted in the construction industry to increase the value of a project by reducing waste and improving construction productivity. Lean emphasizes on maximizing the value of a project with less expenditure. Globally, lean philosophy has received wider popularity in construction sector. Lean construction has supported the practitioners with several tools and techniques to implement at various stages of a construction project. Following the global trends, this study has investigated the lean practice in Pakistan. The level of implementation of different lean tools and techniques altogether with potential benefits experienced by its implementation in construction projects of Pakistan is analyzed. To achieve the targets, the opinion was sought by the practitioners involved in handling construction projects representing four stakeholders that are a client, consultant, contractors and material suppliers through a structured questionnaire. A total of 34 completed questionnaires were collected and then statistically analyzed. The findings of the analysis have highlighted that pull approach, work standardization, just in time, increase visualization tools, integrated project delivery method and fail-safe for quality are common lean techniques implemented in the local construction industry. While reduction in waste, client’s satisfaction, improved communication, visual control and proper task management are major benefits of the lean construction application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lean%20construction" title="lean construction">lean construction</a>, <a href="https://publications.waset.org/abstracts/search?q=lean%20tools%20and%20techniques" title=" lean tools and techniques"> lean tools and techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=lean%20benefits" title=" lean benefits"> lean benefits</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20reduction" title=" waste reduction"> waste reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=Pakistan" title=" Pakistan"> Pakistan</a> </p> <a href="https://publications.waset.org/abstracts/89362/lean-construction-techniques-in-construction-projects-of-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89362.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">287</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">35</span> Chemical Analysis and Cytotoxic Evaluation of Asphodelus Aestivus Brot.

Is a wild plant distributed in Egypt and is considered one of the five Asphodelus spp. from the family Asphodelaceae; it grows in dry grasslands and on rocky or sandy soil. The chemical components of A. aestivus flowers extract were analyzed using different chromatographic and spectral techniques and led to the isolation of two anthraquinones identified as emodin and emodin-O-glucoside. In addition to, five flavonoid compounds;kaempferol,Kaempferol-3-O-glucoside,Apigenin-6-C-glucoside-7-O-glucoside (Saponarine), luteolin 7-O-β-glucopyranoside, Isoorientin-O-malic acid which is a new compound in nature. The LC-ESI-MS/MS analysis of the flower extract of A. aestivus led to the identification of twenty- two compounds characterized by the presence of flavones, flavonols, and flavone C-glycosides. While GC/MS analysis led to the identification of 24 compounds comprising 98.32% of the oil, the major components of the oil were 9, 12, 15-Octadecatrieoic acid methyl ester 28.72%, and 9, 12-Octadecadieroic acid (Z, Z)-methyl ester 19.96%. In vitro cytotoxic activity of the aqueous methanol extract of A. aestivus flowers against HEPG2, HCT-116, MCF-7, and A549 culture was examined and showed moderate inhibition (62.3±1.1)% on HEPG2 cell line followed by (36.8±0.2)% inhibition on HCT-116 and a weak inhibition (5.7± 0.0.2) on MCF-7 cell line followed by (4.5± 0.4) % inhibition on A549 cell line and this is considered the first cytotoxic report of A. aestivus flowers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anthraquinones" title="Anthraquinones">Anthraquinones</a>, <a href="https://publications.waset.org/abstracts/search?q=Asphodelus%20aestivus" title=" Asphodelus aestivus"> Asphodelus aestivus</a>, <a href="https://publications.waset.org/abstracts/search?q=Cytotoxic%20activity" title=" Cytotoxic activity"> Cytotoxic activity</a>, <a href="https://publications.waset.org/abstracts/search?q=Flavonoids" title=" Flavonoids"> Flavonoids</a>, <a href="https://publications.waset.org/abstracts/search?q=LC-ESI-MS%2FMS" title=" LC-ESI-MS/MS"> LC-ESI-MS/MS</a> </p> <a href="https://publications.waset.org/abstracts/131479/chemical-analysis-and-cytotoxic-evaluation-of-asphodelus-aestivus-brot-flowers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131479.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">222</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">34</span> Monitoring of Humoral Immune Response of Monovalent and Combined PPR and FMD Serotype 'O' Virus Vaccines in Goats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mudassar%20Hameed">Mudassar Hameed</a>, <a href="https://publications.waset.org/abstracts/search?q=Khushi%20Muhammad"> Khushi Muhammad</a>, <a href="https://publications.waset.org/abstracts/search?q=Aamir%20Ghafoor"> Aamir Ghafoor</a>, <a href="https://publications.waset.org/abstracts/search?q=Masood%20%20Rabbani"> Masood Rabbani</a>, <a href="https://publications.waset.org/abstracts/search?q=Momena%20Habib"> Momena Habib</a>, <a href="https://publications.waset.org/abstracts/search?q=Jawad%20Nazir"> Jawad Nazir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Comparative efficacy of three formulations (non-adjuvant, gel, and oil adjuvant) of monovalent and combined PPR and FMD virus vaccines was evaluated in goats. All kinds of monovalent PPRV vaccines elicited protective antibody titers at one-month post vaccination (PV) that remained so till six months PV. Monovalent non-adjuvant (NA) FMDV vaccine provoked non-protective antibody titers that declined to undetectable levels after three months. In case of combined vaccines, all of the formulations elicited protective antibody titers against PPRV in vaccinated animals which remained above that limit for six months. However, an exceptional immune response against FMDV was observed in combined NA vaccine group where antibody titers were extremely high and remained above protective level till 4 months PV in animals who received a single vaccine shot and till six months PV in booster group. Although, adjuvant or NA combined vaccines can induce protective antibody titers against both of the viruses within one month PV, but a booster vaccine shot is needed to retain protective antibody level for 6 months duration. Immune response elicited by combined vaccines is comparable or superior to the monovalent vaccines. Hence combined vaccine can be effectively used for the control and prevention of both of the diseases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibody%20titer" title="antibody titer">antibody titer</a>, <a href="https://publications.waset.org/abstracts/search?q=protective" title=" protective"> protective</a>, <a href="https://publications.waset.org/abstracts/search?q=combined%20vaccine" title=" combined vaccine"> combined vaccine</a>, <a href="https://publications.waset.org/abstracts/search?q=non%20adjuvant" title=" non adjuvant"> non adjuvant</a> </p> <a href="https://publications.waset.org/abstracts/83674/monitoring-of-humoral-immune-response-of-monovalent-and-combined-ppr-and-fmd-serotype-o-virus-vaccines-in-goats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83674.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">204</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">33</span> Cognitive Semantics Study of Conceptual and Metonymical Expressions in Johnson's Speeches about COVID-19</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hussain%20Hameed%20Mayuuf">Hussain Hameed Mayuuf</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study is an attempt to investigate the conceptual metonymies is used in political discourse about COVID-19. Thus, this study tries to analyze and investigate how the conceptual metonymies in Johnson's speech about coronavirus are constructed. This study aims at: Identifying how are metonymies relevant to understand the messages in Boris Johnson speeches and to find out how can conceptual blending theory help people to understand the messages in the political speech about COVID-19. Lastly, it tries to Point out the kinds of integration networks are common in political speech. The study is based on the hypotheses that conceptual blending theory is a powerful tool for investigating the intended messages in Johnson's speech and there are different processes of blending networks and conceptual mapping that enable the listeners to identify the messages in political speech. This study presents a qualitative and quantitative analysis of four speeches about COVID-19; they are said by Boris Johnson. The selected data have been tackled from the cognitive-semantic perspective by adopting Conceptual Blending Theory as a model for the analysis. It concludes that CBT is applicable to the analysis of metonymies in political discourse. Its mechanisms enable listeners to analyze and understand these speeches. Also the listener can identify and understand the hidden messages in Biden and Johnson's discourse about COVID-19 by using different conceptual networks. Finally, it is concluded that the double scope networks are the most common types of blending of metonymies in the political speech. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cognitive" title="cognitive">cognitive</a>, <a href="https://publications.waset.org/abstracts/search?q=semantics" title=" semantics"> semantics</a>, <a href="https://publications.waset.org/abstracts/search?q=conceptual" title=" conceptual"> conceptual</a>, <a href="https://publications.waset.org/abstracts/search?q=metonymical" title=" metonymical"> metonymical</a>, <a href="https://publications.waset.org/abstracts/search?q=Covid-19" title=" Covid-19"> Covid-19</a> </p> <a href="https://publications.waset.org/abstracts/157124/cognitive-semantics-study-of-conceptual-and-metonymical-expressions-in-johnsons-speeches-about-covid-19" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157124.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">128</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">32</span> Palygorskite Bearing Calcic-Soils from Western Thar Desert: Implications for Late Quaternary Monsoonal Fluctuations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Hameed">A.

Srivastava</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Main objective the present study is to investigate microscopic, sub-microscopic, clay mineralogical and geochemical characteristics of three calcic soil profiles from the western Thar Desert for the last 30 ka paleoclimatic information. Thin-sections of the soils show weakly to moderately developed pedofeatures dominated by powdery to well-indurated pedogenic calcium carbonate. Sub-microscopy of the representative calcretes show extensive growth of fibrous palygorskite in pore spaces of micritic and sparitic nodules. XRD of the total clay ( < 2 µm) and fine clay ( < 0.2 µm) fractions of the soils show dominance of smectite, palygorskite, chlorite, mica, kaolinite and small amounts of quartz and feldspar. Formation of the palygorskite is attributed to pedogenic processes associated with Bw, Bss and Bwk horizons during drier conditions over the last 30 ka. Formation of palygorskite was mainly favoured by strongly evaporating percolating water and precipitation of secondary calcite, high pH (9-10), high Mg, Si and low Al activities during pedogenesis. Age estimate and distribution of calcretes, palygorskite, and illuvial features indicate fluctuating monsoonal strength during MIS3-MIS1 stages. The pedogenic features in calcic soils of western Thar suggest relatively arid conditions during MIS3-MIS2 transition and LGM time that changed to relatively wetter conditions during post LGM time and again returned to dry conditions at ~4 ka in MIS1. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=palygorskite" title="palygorskite">palygorskite</a>, <a href="https://publications.waset.org/abstracts/search?q=clay%20minerals" title=" clay minerals"> clay minerals</a>, <a href="https://publications.waset.org/abstracts/search?q=Thar" title=" Thar"> Thar</a>, <a href="https://publications.waset.org/abstracts/search?q=aridisol" title=" aridisol"> aridisol</a>, <a href="https://publications.waset.org/abstracts/search?q=late%20quaternary" title=" late quaternary"> late quaternary</a> </p> <a href="https://publications.waset.org/abstracts/85055/palygorskite-bearing-calcic-soils-from-western-thar-desert-implications-for-late-quaternary-monsoonal-fluctuations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85055.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">31</span> Multi-Objective Optimization in Carbon Abatement Technology Cycles (CAT) and Related Areas: Survey, Developments and Prospects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hameed%20Rukayat%20Opeyemi">Hameed Rukayat Opeyemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Pericles%20Pilidis"> Pericles Pilidis</a>, <a href="https://publications.waset.org/abstracts/search?q=Pagone%20Emanuele"> Pagone Emanuele</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An infinitesimal increase in performance can have immense reduction in operating and capital expenses in a power generation system. Therefore, constant studies are being carried out to improve both conventional and novel power cycles. Globally, power producers are constantly researching on ways to minimize emission and to collectively downsize the total cost rate of power plants. A substantial spurt of developmental technologies of low carbon cycles have been suggested and studied, however they all have their limitations and financial implication. In the area of carbon abatement in power plants, three major objectives conflict: The cost rate of the plant, Power output and Environmental impact. Since, an increase in one of this parameter directly affects the other. This poses a multi-objective problem. It is paramount to be able to discern the point where improving one objective affects the other. Hence, the need for a Pareto-based optimization algorithm. Pareto-based optimization algorithm helps to find those points where improving one objective influences another objective negatively and stops there. The application of Pareto-based optimization algorithm helps the user/operator/designer make an informed decision. This paper sheds more light on areas that multi-objective optimization has been applied in carbon abatement technologies in the last five years, developments and prospects. <p
