Development in Gilgit Baltistan has been challenging due to its geographical conditions and the human development indicators are lower than the rest of the Pakistan. Various socioeconomic factors are identified that play an important role in determining the choices and roles men and women undertake for contributing towards the labour force. Our research highlights the areas lagging behind in gender equality in the labour market. The availability and access of gender over these socioeconomic resources determine gender mainstreaming in the labour market. It is a need of time that gender gaps should be addressed at the grass root level by the policy makers to enhance the growth and improve human development indicators. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gender%20division%20of%20work" title="gender division of work">gender division of work</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20development" title=" human development"> human development</a>, <a href="https://publications.waset.org/abstracts/search?q=indicators%20of%20socioeconomic%20factors" title=" indicators of socioeconomic factors"> indicators of socioeconomic factors</a>, <a href="https://publications.waset.org/abstracts/search?q=labour%20force" title=" labour force"> labour force</a> </p> <a href="https://publications.waset.org/abstracts/37835/a-gender-sensitive-labour-policy-for-gilgit-baltistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37835.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">354</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">113</span> Production of Kudzu Starch Gels With Superior Mechanical and Rheological Properties Through Submerged Ethanol Exposure and Implications for in Vitro Digestion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=John-Nelson%20Ekumah">John-Nelson Ekumah</a>, <a href="https://publications.waset.org/abstracts/search?q=Xu%20Han"> Xu Han</a>, <a href="https://publications.waset.org/abstracts/search?q=Qiufang%20Liang"> Qiufang Liang</a>, <a href="https://publications.waset.org/abstracts/search?q=Benxi%20Wei"> Benxi Wei</a>, <a href="https://publications.waset.org/abstracts/search?q=Arif%20Rashid"> Arif Rashid</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Safiullah"> Muhammad Safiullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Qayum"> Abdul Qayum</a>, <a href="https://publications.waset.org/abstracts/search?q=Selorm%20Yao-Say%20Solomon%20Adade"> Selorm Yao-Say Solomon Adade</a>, <a href="https://publications.waset.org/abstracts/search?q=Nana%20Adwoa%20Nkuma%20Johnson"> Nana Adwoa Nkuma Johnson</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdur%20Rehman"> Abdur Rehman</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaofeng%20Ren"> Xiaofeng Ren</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Producing starch gels with superior mechanical attributes remains a challenging pursuit. This research sought to develop a simple method using ethanol exposure to produce robust starch gels. The gels’ mechanical properties, rheology, structural characteristics, and digestion were assessed through textural, rheological, structural, and in vitro digestion analyses. it investigation revealed an improvement in gel’s strength from 62.22 to178.82 g. The thermal transitions were accelerated when ethanol was elevated. The exposure to ethanol resulted in a reduction in syneresis from 11% to 9.5% over a period of 6 hours with noticeable change in size and color. Rheologically, the dominating storage modulus and tan delta (<0.55) emphasized the gel’s improved elasticity. X-ray analysis showed a stable B + V-type pattern after ethanol exposure, with increasing relative crystallinity to 7.9%. Digestibility revealed an ethanol induced resistance, through increased resistant starch from 1.87 to 8.73%. In general, the exposure to ethanol played a crucial role in enhancing the mechanical characteristics of kudzu starch gels, while simultaneously preserving higher levels of resistant starch fractions. These findings have wide-ranging implications in the fields of food and pharmaceuticals, underscoring the extensive academic and industrial importance of this study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=kudzu%20starch%20gels" title="kudzu starch gels">kudzu starch gels</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=rheological%20properties" title=" rheological properties"> rheological properties</a>, <a href="https://publications.waset.org/abstracts/search?q=submerged%20ethanol%20exposure" title=" submerged ethanol exposure"> submerged ethanol exposure</a>, <a href="https://publications.waset.org/abstracts/search?q=In%20vitro%20digestion" title=" In vitro digestion"> In vitro digestion</a> </p> <a href="https://publications.waset.org/abstracts/188373/production-of-kudzu-starch-gels-with-superior-mechanical-and-rheological-properties-through-submerged-ethanol-exposure-and-implications-for-in-vitro-digestion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188373.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">37</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">112</span> Comparison of Small Ruminants (Sheep) Production Efficiency of Nomadic and Transhumance Flocks in Malakand, Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Akbar%20Nawaz%20Khan">Akbar Nawaz Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Ghaffar"> Abdul Ghaffar</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdur%20Rehman"> Abdur Rehman</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Naeem%20Riaz"> Muhammad Naeem Riaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Sayed%20Muhammad%20Hassan%20Andrabi"> Sayed Muhammad Hassan Andrabi </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study was conducted to compare sheep rearing in nomadic with transhumance system in term of production parameters. The following parameters which studied for comparison were household size, landholding area, flock size, body condition score, fecal egg count and live weight change in sheep under nomadic and transhumance systems of management in Malakand since October 2010 to March 2011. Further the effects of Body Condition Score (BCS) and Fecal Egg Count (FEC) on production were also examined. Two systems were checked for the purpose to check the efficiency of production. A total of eight flocks, four each from nomadic and transhumance system were selected for the study; each flock was divided into treatment and controlled groups to check the effect of treatment or de-wormers. A total of 160 animals were selected randomly (80 treated, 80 controlled). The adult ram average weight transhumance system was 55.58 kg while in nomadic that was 54.16 kg, weight change was positive, and the highest change was recorded in transhumance treated which was 13%. Fecal egg count was record low (75 EPG) in transhumance treated group while high (330 EPG) in nomadic controlled. Body condition score was recorded 3.6 for transhumance treated and 3.32 for nomadic treated. It is concluded from the present study that transhumance system performed significantly (p < 0.05) better in respect of live weight, BCS, FEC, family size, Landholding area, number of animals in a flock, offspring record, culling, and mortality. Mean values are 7.367 ± 0221, 0.900 ± 0.071, 63.167 ± 1.559, 55.600 ± 1.480, 8.300 ± 0.321 and 2.500 ± 0.158 respectively. De-wormer effect on FEC showed a significant reduction in egg load in mature sheep on both systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=small%20ruminant" title="small ruminant">small ruminant</a>, <a href="https://publications.waset.org/abstracts/search?q=sheep" title=" sheep"> sheep</a>, <a href="https://publications.waset.org/abstracts/search?q=nomadic" title=" nomadic"> nomadic</a>, <a href="https://publications.waset.org/abstracts/search?q=transhumance" title=" transhumance"> transhumance</a>, <a href="https://publications.waset.org/abstracts/search?q=Malakand" title=" Malakand"> Malakand</a>, <a href="https://publications.waset.org/abstracts/search?q=production%20efficiency" title=" production efficiency"> production efficiency</a> </p> <a href="https://publications.waset.org/abstracts/85727/comparison-of-small-ruminants-sheep-production-efficiency-of-nomadic-and-transhumance-flocks-in-malakand-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85727.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">111</span> A Review Paper on Data Mining and Genetic Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sikander%20Singh%20Cheema">Sikander Singh Cheema</a>, <a href="https://publications.waset.org/abstracts/search?q=Jasmeen%20Kaur"> Jasmeen Kaur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the concept of data mining is summarized and its one of the important process i.e KDD is summarized.

Cheiloscopy is basically the study of elevations and depressions present on the external surface of the lips. In our study, 600 lip prints samples were taken (300 males and 300 females). Lip prints of each individual were divided into four quadrants and the upper middle portion. For general classification, middle part of the lower lip almost 10 mm wide would be taken into consideration. After analysis of lip-prints, our results show that lip prints are the unique and permanent character of every individual. No two lip print was matched with each other even of the identical twins. Our study reveals that there is equal distribution of lip print patterns among all the four quadrants of lips and the upper middle portion; these distributions were statistically analyzed by applying chi-square test which shows the significant results. In general classification, 5 lip print types/patterns were studied, Type 1 (Vertical lines), Type 2 (Branched pattern), Type 3 (Intersected pattern), Type 4 (Reticular pattern) and Type 5 (Undetermined). Type 1 and Type 2 were found to be the most frequent patterns in female population, while Type 3 and Type 4 most commonly found in male population. These results were also analyzed by applying Chi-square test, and the results show significance statistically. Thus, establishing sex determination on the basis of lip print types among the gender. Type 5 was the least common pattern among genders. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cheiloscopy" title="cheiloscopy">cheiloscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=distribution" title=" distribution"> distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=quadrants" title=" quadrants"> quadrants</a>, <a href="https://publications.waset.org/abstracts/search?q=sex%20determination" title=" sex determination"> sex determination</a> </p> <a href="https://publications.waset.org/abstracts/81911/investigating-the-morphological-patterns-of-lip-prints-and-their-effectiveness-in-individualization-and-gender-determination-in-pakistani-population" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81911.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">297</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">108</span> Reduction of Wear via Hardfacing of Rotavator Blades</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gurjinder%20Singh%20Randhawa">Gurjinder Singh Randhawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Jonny%20Garg"> Jonny Garg</a>, <a href="https://publications.waset.org/abstracts/search?q=Sukhraj%20Singh"> Sukhraj Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Gurmeet%20Singh%20Cheema"> Gurmeet Singh Cheema</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A major problem related to the use of rotavator is wear of rotavator blades due to abrasion by soil hard particles, as it seriously affects tillage quality and agricultural production economy. The objective of this study was to increase the wear resistance by covering the rotavator blades with two different hard facing electrodes. These blades are generally produced from low carbon or low alloy steel. During the field work i.e. preparing land for the cultivation these blades are subjected to severe wear conditions. Comparative wear tests on a regular rotavator blade and two kinds of hardfacing with electrodes were conducted in the field. These two different hardfacing electrodes, which are designated HARD ALLOY-400 and HARD ALLOY-650, were used for hardfacing.

Recently, finite elements have been used to model rotordynamic system as it offers higher accuracy. However, it involves high degrees of freedom. In some applications such as control design, this requires higher cost. For this reason, various model reduction methods have been proposed. This work demonstrates the quality of model reduction of rotor-bearing-support system through substructuring. The quality of the model reduction is evaluated by comparing some first natural frequencies, modal damping ratio, critical speeds and response of both the full system and the reduced system. The simulation shows that the substructuring is proven adequate to reduce finite element rotor model in the frequency range of interest as long as the numbers and the locations of master nodes are determined appropriately. However, the reduction is less accurate in an unstable or nearly-unstable system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rotordynamic" title="rotordynamic">rotordynamic</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20model" title=" finite element model"> finite element model</a>, <a href="https://publications.waset.org/abstracts/search?q=timoshenko%20beam" title=" timoshenko beam"> timoshenko beam</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20solid%20elements" title=" 3D solid elements"> 3D solid elements</a>, <a href="https://publications.waset.org/abstracts/search?q=Guyan%20reduction%20method" title=" Guyan reduction method "> Guyan reduction method </a> </p> <a href="https://publications.waset.org/abstracts/2730/reduction-of-rotor-bearing-support-finite-element-model-through-substructuring" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2730.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">272</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">105</span> An Analysis and Design of Mobile Payment System Based on NFC Technology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shafiq%20ur%20Rehman">Shafiq ur Rehman</a>, <a href="https://publications.waset.org/abstracts/search?q=Zubair%20Ahmed%20Shaikh"> Zubair Ahmed Shaikh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research provides the comparative study of different mobile payment system and proposes an efficient solution of mobile payment system.

The research explored the synthesis of chiral transition metal complexes containing these ligands and their applications in various asymmetric catalytic transformations. Herein, the transition metal complexes having ruthenium(II), rhodium(I) and iridium(I) metal centres will be discussed. These are air stable complexes and were characterized by CHN analysis, 1H, 13C, and 31P NMR spectroscopy, and polarimetry. Currently, there is an emphasis on 'greener' catalysts and the need for 'green' solvents in asymmetric catalysis. As such, the Ph-Garphos ligands were demethylated thereby introducing hydroxyl moieties unto the ligand scaffold. The facile tunability of the biaryl diphosphines led to the preparation of the (R)-(4,4',6,6'-tetrahydroxybiphenyl-2,2'-diyl)bis(diphenylphosphine) (R-Ph-Garphos-OH), and (S)-(4,4',6,6'-tetrahydroxybiphenyl-2,2'-diyl)bis(diphenylphosphine) (S-Ph-Garphos-OH) ligands. These were successfully characterized by CHN analysis, 1H, 13C, and 31P NMR spectroscopy, and polarimetry. The use of the Ph-Garphos and Ph-Garphos-OH ligands and their transition metal complexes in asymmetric hydrogenations will be reported. Additionally, the scope of the research will highlight the applicability of the Ph-Garphos-OH ligand and its transitional metal complexes as 'green' catalysts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=catalysis" title="catalysis">catalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20hydrogenation" title=" asymmetric hydrogenation"> asymmetric hydrogenation</a>, <a href="https://publications.waset.org/abstracts/search?q=diphosphine%20transition%20metal%20complexes" title=" diphosphine transition metal complexes"> diphosphine transition metal complexes</a>, <a href="https://publications.waset.org/abstracts/search?q=Ph-Garphos%20ligands" title=" Ph-Garphos ligands"> Ph-Garphos ligands</a> </p> <a href="https://publications.waset.org/abstracts/70174/chiral-diphosphine-ligands-and-their-transition-metal-diphosphine-complexes-in-asymmetric-catalysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70174.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">309</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">100</span> Developing an Empirical Relationship to Predict Tensile Strength and Micro Hardness of Friction Stir Welded Aluminium Alloy Joints </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gurmeet%20Singh%20Cheema">Gurmeet Singh Cheema</a>, <a href="https://publications.waset.org/abstracts/search?q=Gurjinder%20Singh"> Gurjinder Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Amardeep%20Singh%20Kang"> Amardeep Singh Kang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aluminium alloy 6061 is a medium to high strength heat-treatable alloy which has very good corrosion resistance and very good weldability.

A firewall can't protect you against all the hazards of unauthorized networks. Consequently, many kinds of infrastructure are employed to establish a secure network. Firewall strategies have already been the subject of significant analysis. This study's primary purpose is to avoid unnecessary connections by combining the capability of the firewall with the use of additional firewall mechanisms, which include packet filtering and NAT, VPNs, and backdoor solutions. There are insufficient studies on firewall potential and combined approaches, but there aren't many. The research team's goal is to build a safe network by integrating firewall strength and firewall methods. The study's findings indicate that the recommended concept can form a reliable network. This study examines the characteristics of network security and the primary danger, synthesizes existing domestic and foreign firewall technologies, and discusses the theories, benefits, and disadvantages of different firewalls. Through synthesis and comparison of various techniques, as well as an in-depth examination of the primary factors that affect firewall effectiveness, this study investigated firewall technology's current application in computer network security, then introduced a new technique named "tight coupling firewall." Eventually, the article discusses the current state of firewall technology as well as the direction in which it is developing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=firewall%20strategies" title="firewall strategies">firewall strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=firewall%20potential" title=" firewall potential"> firewall potential</a>, <a href="https://publications.waset.org/abstracts/search?q=packet%20filtering" title=" packet filtering"> packet filtering</a>, <a href="https://publications.waset.org/abstracts/search?q=NAT" title=" NAT"> NAT</a>, <a href="https://publications.waset.org/abstracts/search?q=VPN" title=" VPN"> VPN</a>, <a href="https://publications.waset.org/abstracts/search?q=proxy%20services" title=" proxy services"> proxy services</a>, <a href="https://publications.waset.org/abstracts/search?q=firewall%20techniques" title=" firewall techniques"> firewall techniques</a> </p> <a href="https://publications.waset.org/abstracts/148108/methods-for-restricting-unwanted-access-on-the-networks-using-firewall" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148108.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">101</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">97</span> Magnetohydrodynamic 3D Maxwell Fluid Flow Towards a Horizontal Stretched Surface with Convective Boundary Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Y.%20Malika">M.

The unique combination of soft phosphorus (P) and hard nitrogen (N) centres affords a variety of transition metal complexes as potential pre-catalysts for synthetically useful reactions. Herein three ligand systems will be reported; two bidentate ligands - (S)-8-(diphenyl-phosphino)-1,2,3,4-tetrahydronaphthalen-1-amine, (S)THNANH2, and (Rc)-1-((Sp)-2-diphenylphosphino) ferrocenylethylamine, (RcSp)PPFNH2 - and a tridentate (Rc)-1-((Sp)-2-diphenylphosphino) ferrocenylimino-pyridine, (RcSp)PPFNNH2 ligand; the latter prepared from the condensation of selected ferrocene aminophosphines with pyridine-2-carboxaldehyde. Suitable combinations of these aminophosphine ligands with ruthenium precursors have afforded highly efficient systems for the asymmetric hydrogenation and transfer hydrogenation of selected ketones in 2-propanol. The Ru-(S)THNANH2 precatalyst was the most efficient in the asymmetric hydrogenation of selected ketones with 100% conversions within 4 hours at a catalyst loading of 0.1 mol%. The Ru-(RcSp)PPFNNH2 precatalyst was the most efficient in the asymmetric transfer hydrogenation of the ketones with conversions as high as 98% with 0.1 mol% catalyst. However, the enantioselectivities were generally low. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aminophosphine" title="aminophosphine">aminophosphine</a>, <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20hydrogenation" title=" asymmetric hydrogenation"> asymmetric hydrogenation</a>, <a href="https://publications.waset.org/abstracts/search?q=homogeneous%20catalysis" title=" homogeneous catalysis"> homogeneous catalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=ruthenium%20%28II%29" title=" ruthenium (II)"> ruthenium (II)</a>, <a href="https://publications.waset.org/abstracts/search?q=transfer%20hydrogenation" title=" transfer hydrogenation"> transfer hydrogenation</a> </p> <a href="https://publications.waset.org/abstracts/70318/chiral-ruthenium-aminophosphine-and-phosphine-iminopyridine-complexes-synthesis-and-application-to-asymmetric-hydrogenation-and-transfer-hydrogenation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70318.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">261</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">95</span> Analysis of Fixed Beamforming Algorithms for Smart Antenna Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Umair%20Shahid">Muhammad Umair Shahid</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Rehman"> Abdul Rehman</a>, <a href="https://publications.waset.org/abstracts/search?q=Mudassir%20Mukhtar"> Mudassir Mukhtar</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Nauman"> Muhammad Nauman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The smart antenna is the prominent technology that has become known in recent years to meet the growing demands of wireless communications.

This research aims to determine the serotype distribution of dengue virus during this outbreak and classify the patients demographically. 5ml of venous blood was drawn aseptically from 166 patients with dengue-like signs to test for the virus between the months of August to November 2011. The samples were sent to the CDC, Atlanta, Georgia for the purpose of molecular assays to determine their serotype. RT-PCR protocol was performed targeting at the 4 dengue serotypes. Out of 166 cases, dengue infection was detected with RT-PCR in 95 cases, all infected with same serotype DEN-2. 75% of positive cases were males while 25% were females. Most positive patients were in the age range of 16-30 years. 33% positive cases had accompanying bleeding. This is first study during the 2011 dengue epidemic in Lahore that reports DEN-2 as the only prevalent serotype. It also indicates that more infected patients were males, adults, within age range of 16-30 years, peaked in the month of November, Dengue hemorrhagic fever (DHF) is manifested more in females, Ravi town was heavily hit by dengue virus infection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dengue" title="dengue">dengue</a>, <a href="https://publications.waset.org/abstracts/search?q=serotypes" title=" serotypes"> serotypes</a>, <a href="https://publications.waset.org/abstracts/search?q=Pakistan" title=" Pakistan"> Pakistan</a>, <a href="https://publications.waset.org/abstracts/search?q=DEN%202" title=" DEN 2"> DEN 2</a>, <a href="https://publications.waset.org/abstracts/search?q=Lahore" title=" Lahore"> Lahore</a>, <a href="https://publications.waset.org/abstracts/search?q=demography" title=" demography"> demography</a>, <a href="https://publications.waset.org/abstracts/search?q=serotype%20distrbution" title=" serotype distrbution"> serotype distrbution</a>, <a href="https://publications.waset.org/abstracts/search?q=2011%20epidemic" title=" 2011 epidemic "> 2011 epidemic </a> </p> <a href="https://publications.waset.org/abstracts/1935/serotype-distribution-and-demographics-of-dengue-patients-in-a-tertiary-hospital-of-lahore-pakistan-during-the-2011-epidemic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1935.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">500</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">93</span> Chemical Bath Deposition Technique (CBD) of Cds Used in Closed Space Sublimation (CSS) of CdTe Solar Cell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zafar%20Mahmood">Zafar Mahmood</a>, <a href="https://publications.waset.org/abstracts/search?q=Fahimullah%20Babar"> Fahimullah Babar</a>, <a href="https://publications.waset.org/abstracts/search?q=Surriyia%20Naz"> Surriyia Naz</a>, <a href="https://publications.waset.org/abstracts/search?q=Hafiz%20Ur%20Rehman"> Hafiz Ur Rehman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cadmium Sulphide (CdS) was deposited on a Tec 15 glass substrate with the help of CBD (chemical bath deposition process) and then cadmium telluride CdTe was deposited on CdS with the help of CSS (closed spaced sublimation technique) for the construction of a solar cell.

Being situated in a seismically active region, seismic safety evaluation of flyovers is essential for seismic risk reduction. Effects of site amplification on seismic safety evaluation of flyover piers are the main concern of this study. In this regard, failure mode, lateral strength and displacement ductility of piers of a typical multi-span simply supported flyover have been evaluated by Japan Road Association (JRA) recommended guidelines, with and without considering site amplification. Ultimate flexural strengths of piers have been computed using the pushover analysis results. Shear capacity of piers has been calculated using the guidelines of JRA. Lateral strengths have been determined depending on the failure modes of the piers. Displacement ductility of piers has been computed using yield and ultimate displacements of the piers obtained from the pushover analysis results. Selected earthquake time history is used in seismic safety evaluation of the flyover piers. Finally, the ductility design method is used to conduct the seismic safety evaluation of the piers with and without considering site amplification.

The thicknesses of all the deposited materials were measured with the help of Ellipsometry. The IV graphs were drawn in order to observe the current voltage output. The efficiency of the cell was graphed with the fill factor as well (graphs not given here). The efficiency came out to be approximately 16.5 % and the CIGS (copper-indium–gallium-selenide) maximum efficiency is 20 %. The efficiency of a solar cell can further be enhanced by adapting quality materials, good experimental devices and proper procedures. The grain size was analyzed with the help of scanning electron microscope using RBS (Rutherford backscattering spectroscopy). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chemical%20Bath%20Deposition%20Technique%20%28CBD%29" title="Chemical Bath Deposition Technique (CBD)">Chemical Bath Deposition Technique (CBD)</a>, <a href="https://publications.waset.org/abstracts/search?q=cadmium%20sulphide%20%28CdS%29" title=" cadmium sulphide (CdS)"> cadmium sulphide (CdS)</a>, <a href="https://publications.waset.org/abstracts/search?q=CdTe" title=" CdTe"> CdTe</a>, <a href="https://publications.waset.org/abstracts/search?q=CSS%20%28Closed%20Space%20Sublimation%29" title=" CSS (Closed Space Sublimation)"> CSS (Closed Space Sublimation)</a> </p> <a href="https://publications.waset.org/abstracts/49998/chemical-bath-deposition-technique-of-cds-used-in-closed-space-sublimation-of-cdte-solar-cell" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49998.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">364</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">87</span> Application of Soft Sets to Non-Associative Rings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Inayatur%20Rehman">Inayatur Rehman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Molodtstove developed the theory of soft sets which can be seen as an effective tool to deal with uncertainties. Since the introduction of this concept, the application of soft sets has been restricted to associative algebraic structures (groups, semi groups, associative rings, semi-rings etc.). Acceptably, though the study of soft sets, where the base set of parameters is a commutative structure, has attracted the attention of many researchers for more than one decade. But on the other hand there are many sets which are naturally endowed by two compatible binary operations forming a non-associative ring and we may dig out examples which investigate a non-associative structure in the context of soft sets. Thus it seems natural to apply the concept of soft sets to non-commutative and non-associative structures. In present paper, we make a new approach to apply Molodtsoves notion of soft sets to LA-ring (a class of non-associative ring). We extend the study of soft commutative rings from theoretical aspect. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soft%20sets" title="soft sets">soft sets</a>, <a href="https://publications.waset.org/abstracts/search?q=LA-rings" title=" LA-rings"> LA-rings</a>, <a href="https://publications.waset.org/abstracts/search?q=soft%20LA-rings" title=" soft LA-rings"> soft LA-rings</a>, <a href="https://publications.waset.org/abstracts/search?q=soft%20ideals" title=" soft ideals"> soft ideals</a>, <a href="https://publications.waset.org/abstracts/search?q=soft%20prime%20ideals" title=" soft prime ideals"> soft prime ideals</a>, <a href="https://publications.waset.org/abstracts/search?q=idealistic%0D%0Asoft%20LA-rings" title=" idealistic soft LA-rings"> idealistic soft LA-rings</a>, <a href="https://publications.waset.org/abstracts/search?q=LA-ring%20homomorphism" title=" LA-ring homomorphism "> LA-ring homomorphism </a> </p> <a href="https://publications.waset.org/abstracts/33475/application-of-soft-sets-to-non-associative-rings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33475.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">463</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">86</span> Geospatial Techniques and VHR Imagery Use for Identification and Classification of Slums in Gujrat City, Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Ameer%20Nawaz%20Akram">Muhammad Ameer Nawaz Akram</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The 21st century has been revealed that many individuals around the world are living in urban settlements than in rural zones. The evolution of numerous cities in emerging and newly developed countries is accompanied by the rise of slums. The precise definition of a slum varies countries to countries, but the universal harmony is that slums are dilapidated settlements facing severe poverty and have lacked access to sanitation, water, electricity, good living styles, and land tenure. The slum settlements always vary in unique patterns within and among the countries and cities. The core objective of this study is the spatial identification and classification of slums in Gujrat city Pakistan from very high-resolution GeoEye-1 (0.41m) satellite imagery. Slums were first identified using GPS for sample site identification and ground-truthing; through this process, 425 slums were identified. Then Object-Oriented Analysis (OOA) was applied to classify slums on digital image. Spatial analysis softwares, e.g., ArcGIS 10.3, Erdas Imagine 9.3, and Envi 5.1, were used for processing data and performing the analysis. Results show that OOA provides up to 90% accuracy for the identification of slums. Jalal Cheema and Allah Ho colonies are severely affected by slum settlements. The ratio of criminal activities is also higher here than in other areas. Slums are increasing with the passage of time in urban areas, and they will be like a hazardous problem in coming future. So now, the executive bodies need to make effective policies and move towards the amelioration process of the city. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=slums" title="slums">slums</a>, <a href="https://publications.waset.org/abstracts/search?q=GPS" title=" GPS"> GPS</a>, <a href="https://publications.waset.org/abstracts/search?q=satellite%20imagery" title=" satellite imagery"> satellite imagery</a>, <a href="https://publications.waset.org/abstracts/search?q=object%20oriented%20analysis" title=" object oriented analysis"> object oriented analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=zonal%20change%20detection" title=" zonal change detection"> zonal change detection</a> </p> <a href="https://publications.waset.org/abstracts/119513/geospatial-techniques-and-vhr-imagery-use-for-identification-and-classification-of-slums-in-gujrat-city-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/119513.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">134</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">85</span> Analysis of Two-Phase Flow Instabilities in Conventional Channel of Nuclear Power Reactor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Abdur%20Rashid%20Sarkar">M.

A two phase flow is susceptible to thermal-hydrodynamic instabilities, which may cause flow oscillations of constant amplitude or diverging amplitude. These oscillations may induce boiling crisis, disturb control systems, or cause mechanical damage. Based on their mechanisms, various types of instabilities can be classified for a nuclear reactor. From a practical engineering point of view one of the major design difficulties in dealing with multiphase flow is that the mass, momentum, and energy transfer rates and processes may be quite sensitive to the geometric configuration of the heat transfer surface. Moreover, the flow within each phase or component will clearly depend on that geometric configuration. The complexity of this two-way coupling presents a major challenge in the study of multiphase flows and there is much that remains to be done. Yet, the parametric effects on flow instability such as the effect of aspect ratio, pressure drop, channel length, its orientation inlet subcooling and surface roughness etc. have been analyzed. Another frequently occurring instability, known as the Kelvin–Helmholtz instability has been briefly reviewed. Various analytical techniques for predicting parametric effect on the instability are analyzed in terms of their applicability and accuracy. <p class="card-text"><strong>Keywords:</strong> <a
