A cycle of G is a sequence of vertices of G such that the first and the last vertices are the same. A hamiltonian cycle of G is a cycle containing all vertices of G. The graph G is k-ordered (resp. k-ordered hamiltonian) if for any sequence of k distinct vertices of G, there exists a cycle (resp. hamiltonian cycle) in G containing these k vertices in the specified order. Obviously, any cycle in a graph is 1-ordered, 2-ordered and 3-ordered. Thus the study of any graph being k-ordered (resp. k-ordered hamiltonian) always starts with k = 4. Most studies about this topic work on graphs with no real applications. To our knowledge, the chordal ring families were the first one utilized as the underlying topology in interconnection networks and shown to be 4-ordered [1]. Furthermore, based on computer experimental results in [1], it was conjectured that some of them are 4-ordered hamiltonian. In this paper, we intend to give some possible directions in proving the conjecture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamiltonian%20cycle" title="Hamiltonian cycle">Hamiltonian cycle</a>, <a href="https://publications.waset.org/abstracts/search?q=4-ordered" title=" 4-ordered"> 4-ordered</a>, <a href="https://publications.waset.org/abstracts/search?q=Chordal%20rings" title=" Chordal rings"> Chordal rings</a>, <a href="https://publications.waset.org/abstracts/search?q=3-regular" title=" 3-regular"> 3-regular</a> </p> <a href="https://publications.waset.org/abstracts/13946/a-further-study-on-the-4-ordered-property-of-some-chordal-ring-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13946.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">434</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">3198</span> The Effect of Catastrophic Losses on Insurance Cycle: Case of Croatia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Drago%20Jakov%C4%8Devi%C4%87">Drago Jakovčević</a>, <a href="https://publications.waset.org/abstracts/search?q=Maja%20Mihelja%20%C5%BDaja"> Maja Mihelja Žaja</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper provides an analysis of the insurance cycle in the Republic of Croatia and whether they are affected by catastrophic losses on a global level. In general, it is considered that insurance cycles are particularly pronounced in periods of financial crisis, but are also affected by the growing number of catastrophic losses. They cause the change of insurance cycle and premium growth and intensification and narrowing of the coverage conditions, so these variables move in the same direction and these phenomena point to a new cycle.

Power generation is an effective way to utilize low-temperature waste heat and LNG cold energy simultaneously. Organic Rankine Cycles (ORCs) and CO<sub>2</sub> power cycles are promising technologies to convert low-temperature waste heat and LNG cold energy into electricity. If waste heat and LNG cold energy are utilized simultaneously in one system, the performance may outperform separate systems utilizing low-temperature waste heat and LNG cold energy, respectively. Low-temperature waste heat acts as the heat source and LNG regasification acts as the heat sink in the combined system. Due to the large temperature difference between the heat source and the heat sink, cascaded power cycle configurations are proposed in this paper. Cascaded power cycles can improve the energy efficiency of the system considerably. The cycle operating at a higher temperature to recover waste heat is called top cycle and the cycle operating at a lower temperature to utilize LNG cold energy is called bottom cycle in this study. The top cycle condensation heat is used as the heat source in the bottom cycle. The top cycle can be an ORC, transcritical CO<sub>2</sub> (tCO<sub>2</sub>) cycle or supercritical CO<sub>2</sub> (sCO<sub>2</sub>) cycle, while the bottom cycle only can be an ORC due to the low-temperature range of the bottom cycle. However, the thermodynamic path of the tCO<sub>2</sub> cycle and sCO<sub>2</sub> cycle are different from that of an ORC. The tCO<sub>2</sub> cycle and the sCO<sub>2</sub> cycle perform better than an ORC for sensible waste heat recovery due to a better temperature match with the waste heat source. Different combinations of the tCO<sub>2</sub> cycle, sCO<sub>2</sub> cycle and ORC are compared to screen the best configurations of the cascaded power cycles. The influence of the working fluid and the operating conditions are also investigated in this study. Each configuration is modeled and optimized in Aspen HYSYS. The results show that cascaded tCO<sub>2</sub>/ORC performs better compared with cascaded ORC/ORC and cascaded sCO<sub>2</sub>/ORC for the case study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LNG%20cold%20energy" title="LNG cold energy">LNG cold energy</a>, <a href="https://publications.waset.org/abstracts/search?q=low-temperature%20waste%20heat" title=" low-temperature waste heat"> low-temperature waste heat</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20Rankine%20cycle" title=" organic Rankine cycle"> organic Rankine cycle</a>, <a href="https://publications.waset.org/abstracts/search?q=supercritical%20CO%E2%82%82%20cycle" title=" supercritical CO₂ cycle"> supercritical CO₂ cycle</a>, <a href="https://publications.waset.org/abstracts/search?q=transcritical%20CO%E2%82%82%20cycle" title=" transcritical CO₂ cycle"> transcritical CO₂ cycle</a> </p> <a href="https://publications.waset.org/abstracts/86899/cascaded-transcriticalsupercritical-co2-cycles-and-organic-rankine-cycles-to-recover-low-temperature-waste-heat-and-lng-cold-energy-simultaneously" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86899.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">260</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">3196</span> A Study on the Accelerated Life Cycle Test Method of the Motor for Home Appliances by Using Acceleration Factor </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Youn-Sung%20Kim">Youn-Sung Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Mi-Sung%20Kim"> Mi-Sung Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae-Kun%20Lee"> Jae-Kun Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper deals with the accelerated life cycle test method of the motor for home appliances that demand high reliability. Life Cycle of parts in home appliances also should be 10 years because life cycle of the home appliances such as washing machine, refrigerator, TV is at least 10 years. In case of washing machine, the life cycle test method of motor is advanced for 3000 cycle test (1cycle = 2hours). However, 3000 cycle test incurs loss for the time and cost. Objectives of this study are to reduce the life cycle test time and the number of test samples, which could be realized by using acceleration factor for the test time and reduction factor for the number of sample. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accelerated%20life%20cycle%20test" title="accelerated life cycle test">accelerated life cycle test</a>, <a href="https://publications.waset.org/abstracts/search?q=motor%20reliability%20test" title=" motor reliability test"> motor reliability test</a>, <a href="https://publications.waset.org/abstracts/search?q=motor%20for%20washing%20machine" title=" motor for washing machine"> motor for washing machine</a>, <a href="https://publications.waset.org/abstracts/search?q=BLDC%20motor" title=" BLDC motor"> BLDC motor</a> </p> <a href="https://publications.waset.org/abstracts/46400/a-study-on-the-accelerated-life-cycle-test-method-of-the-motor-for-home-appliances-by-using-acceleration-factor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46400.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">635</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">3195</span> On the Basis Number and the Minimum Cycle Bases of the Wreath Product of Paths with Wheels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20M.%20M.%20Jaradat">M.

The cycle space, C(G), of a graph G is the vector subspace of (E; ⊕; .) spanned by the cycles of G. Traditionally there have been two notions of minimality among bases of C(G). First, a basis B of G is called a d-fold if each edge of G occurs in at most d cycles of the basis B. The basis number, b(G), of G is the least non-negative integer d such that C(G) has a d-fold basis; a required basis of C(G) is a basis for which each edge of G belongs to at most b(G) elements of B. Second, a basis B is called a minimum cycle basis (MCB) if its total length Σ BϵB |B| is minimum among all bases of C(G). The lexicographic product GρH has the vertex set V (GρH) = V (G) x V (H) and the edge set E(GρH) = {(u1, v1)(u2, v2)|u1 = u2 and v1 v2 ϵ E(H); or u1u2 ϵ E(G) and there is α ϵ Aut(H) such that α (v1) = v2}. In this work, a construction of a minimum cycle basis for the wreath product of wheels with paths is presented. Also, the length of the longest cycle of a minimum cycle basis is determined. Moreover, the basis number for the wreath product of the same is investigated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cycle%20space" title="cycle space">cycle space</a>, <a href="https://publications.waset.org/abstracts/search?q=minimum%20cycle%20basis" title=" minimum cycle basis"> minimum cycle basis</a>, <a href="https://publications.waset.org/abstracts/search?q=basis%20number" title=" basis number"> basis number</a>, <a href="https://publications.waset.org/abstracts/search?q=wreath%20product" title=" wreath product"> wreath product</a> </p> <a href="https://publications.waset.org/abstracts/2144/on-the-basis-number-and-the-minimum-cycle-bases-of-the-wreath-product-of-paths-with-wheels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2144.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">280</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">3194</span> Comparative Exergy Analysis of Ammonia-Water Rankine Cycles and Kalina Cycle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kyoung%20Hoon%20Kim">Kyoung Hoon Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a comparative exergy analysis of ammonia-water Rankine cycles with and without regeneration and Kalina cycle for recovery of low-temperature heat source.

An S-CO2 cycle that recovers heat from small industrial and aeroderivative gas turbines can outperform a steam-bottoming cycle despite its simplicity and compactness. In using S-CO2 power cycles for waste heat recovery, a split cycle was studied to maximize the net output power by incorporating the utilization efficiency of the waste heat (lowering the temperature of the exhaust gas through the heater) along with the thermal efficiency of the cycle (minimizing the temperature difference for the heat transfer, exergy loss). The cooling condition of the S-CO2 WHR system has a great impact on the performance and the optimum low pressure of the system. Furthermore, the optimum high pressure of the S-CO2 WHR systems for the maximum power from the given heat sources is dependent on the temperature of the waste heat source. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=exergy%20loss" title="exergy loss">exergy loss</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20turbine" title=" gas turbine"> gas turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=supercritical%20CO2%20power%20cycle" title=" supercritical CO2 power cycle"> supercritical CO2 power cycle</a>, <a href="https://publications.waset.org/abstracts/search?q=split%20cycle" title=" split cycle"> split cycle</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20heat%20recovery" title=" waste heat recovery"> waste heat recovery</a> </p> <a href="https://publications.waset.org/abstracts/59112/optimization-of-supercritical-co2-power-cycle-for-waste-heat-recovery-from-gas-turbine-with-respect-to-cooling-condition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59112.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">349</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">3192</span> Thermodynamic Optimization of an R744 Based Transcritical Refrigeration System with Dedicated Mechanical Subcooling Cycle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mihir%20Mouchum%20Hazarika">Mihir Mouchum Hazarika</a>, <a href="https://publications.waset.org/abstracts/search?q=Maddali%20Ramgopal"> Maddali Ramgopal</a>, <a href="https://publications.waset.org/abstracts/search?q=Souvik%20Bhattacharyya"> Souvik Bhattacharyya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The thermodynamic analysis shows that the performance of the R744 based transcritical refrigeration cycle drops drastically for higher ambient temperatures. This is due to the peculiar s-shape of the isotherm in the supercritical region. However, subcooling of the refrigerant at the gas cooler exit enhances the performance of the R744 based system. The present study is carried out to analyze the R744 based transcritical system with dedicated mechanical subcooling cycle. Based on this proposed cycle, the thermodynamic analysis is performed, and optimum operating parameters are determined. The amount of subcooling and the pressure ratio in the subcooling cycle are the parameters which are needed to be optimized to extract the maximum COP from this proposed cycle. It is expected that this study will be helpful in implementing the dedicated subcooling cycle with R744 based transcritical system to improve the performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optimization" title="optimization">optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=R744" title=" R744"> R744</a>, <a href="https://publications.waset.org/abstracts/search?q=subcooling" title=" subcooling"> subcooling</a>, <a href="https://publications.waset.org/abstracts/search?q=transcritical" title=" transcritical"> transcritical</a> </p> <a href="https://publications.waset.org/abstracts/65947/thermodynamic-optimization-of-an-r744-based-transcritical-refrigeration-system-with-dedicated-mechanical-subcooling-cycle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65947.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">306</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3191</span> The Vertex Degree Distance of One Vertex Union of the Cycle and the Star</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ying%20Wang">Ying Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Haiyan%20Xie"> Haiyan Xie</a>, <a href="https://publications.waset.org/abstracts/search?q=Aoming%20Zhang"> Aoming Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The degree distance of a graph is a graph invariant that is more sensitive than the Wiener index.

The first is the cycle is a Brayton cycle, describing the evolution of a classical turboshaft, based on the Klimov TV2 engine. The other two cycles aim at approaching an Ericsson cycle, by replacing the Brayton cycle adiabatic expansion in the turbine by quasi-isothermal expansion. The maximum quasi-Ericsson cycles temperature is set to a lower value than the maximum Brayton cycle temperature, equal to the Brayton cycle power turbine inlet temperature, in order to decrease the engine NOx emissions. Also, the power distribution over the stages of the gas generator turbine is maintained the same. In the first of the two considered quasi-Ericsson cycle, the efficiencies of the gas generator turbine stage. Also, the power distribution over the stages of the gas generator turbine is maintained the same. In the first of the two considered quasi-Ericsson cycle, the efficiencies of the gas generator turbine stages are maintained the same as for the reference case, while for the second, the efficiencies are increased in order to obtain the same shaft power as in the reference case. It is found that in the first case, both the shaft power and the thermodynamic efficiency of the engine decrease, while in the second, the power is maintained, and even a slight increase in efficiency can be noted. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=combustion" title="combustion">combustion</a>, <a href="https://publications.waset.org/abstracts/search?q=Ericsson" title=" Ericsson"> Ericsson</a>, <a href="https://publications.waset.org/abstracts/search?q=thermodynamic%20analysis" title=" thermodynamic analysis"> thermodynamic analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=turbine" title=" turbine "> turbine </a> </p> <a href="https://publications.waset.org/abstracts/28151/thermodynamic-cycle-analysis-for-overall-efficiency-improvement-and-temperature-reduction-in-gas-turbines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28151.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">610</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">3187</span> The Relation between Body Mass Index and Menstrual Cycle Disorders in Medical Students of University Pelita Harapan, Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gabriella%20Tjondro">Gabriella Tjondro</a>, <a href="https://publications.waset.org/abstracts/search?q=Julita%20Dortua%20Laurentina%20Nainggolan"> Julita Dortua Laurentina Nainggolan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: There are several things affecting menstrual cycle, namely, nutritional status, diet, financial status of one’s household and exercises. The most commonly used parameter to calculate the fat in a human body is body mass index. Therefore, it is necessary to do research to prevent complications caused by menstrual disorder in the future. Design Study: This research is an observational analytical study with the cross-sectional-case control approach. Participants (n = 124; median age = 19.5 years ± SD 3.5) were classified into 2 groups: normal, NM (n = 62; BMI = 18-23 kg/m<sup>2</sup>) and obese, OB (n = 62; BMI = > 25 kg/m<sup>2</sup>). BMI was calculated from the equation; BMI = weight, kg/height, m<sup>2</sup>. Results: There were 79.10% from obese group who experienced menstrual cycle disorders (n=53, 79.10%; p value 0.00; OR 5.25) and 20.90% from normal BMI group with menstrual cycle disorders. There were several factors in this research that also influence the menstrual cycle disorders such as stress (44.78%; p value 0.00; OR 1.85), sleep disorders (25.37%; p value 0.00; OR 1.01), physical activities (25.37%; p value 0.00; OR 1.24) and diet (10.45%; p value 0.00; OR 1.07). Conclusion: There is a significant relation between body mass index (obese) and menstrual cycle disorders. However, BMI is not the only factor that affects the menstrual cycle disorders. There are several factors that also can affect menstrual cycle disorders, in this study we use stress, sleep disorders, physical activities and diet, in which none of them are dominant. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=menstrual%20disorders" title="menstrual disorders">menstrual disorders</a>, <a href="https://publications.waset.org/abstracts/search?q=menstrual%20cycle" title=" menstrual cycle"> menstrual cycle</a>, <a href="https://publications.waset.org/abstracts/search?q=obesity" title=" obesity"> obesity</a>, <a href="https://publications.waset.org/abstracts/search?q=body%20mass%20index" title=" body mass index"> body mass index</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress"> stress</a>, <a href="https://publications.waset.org/abstracts/search?q=sleep%20disorders" title=" sleep disorders"> sleep disorders</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20activities" title=" physical activities"> physical activities</a>, <a href="https://publications.waset.org/abstracts/search?q=diet" title=" diet"> diet</a> </p> <a href="https://publications.waset.org/abstracts/101172/the-relation-between-body-mass-index-and-menstrual-cycle-disorders-in-medical-students-of-university-pelita-harapan-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101172.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">148</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">3186</span> Enhancing Children’s English Vocabulary Acquisition through Digital Storytelling at Happy Kids Kindergarten, Palembang, Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gaya%20Tridinanti">Gaya Tridinanti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Enhanching English vocabulary in early childhood is the main problem often faced by teachers. Thus, the purpose of this study was to determine the enhancement of children’s English vocabulary acquisition by using digital storytelling. This type of research was an action research. It consisted of a series of four activities done in repeated cycles: planning, implementation, observation, and reflection.

An approach to determining the distribution function of the measured parameter (Y ̅) is presented, resulting in a more precise method to establish the upper and lower control limits.

This huge data make environment more and more caotic. Data are main piller of intelligence. The affiliation between intelligence and knowledge is quite significant to understand underlying truths. The data gathered from different sources can be modified, interpreted and classified by using intelligence cycle process. This process is applied in order to progress to wisdom as well as intelligence. Within this process the effect of tacit knowledge is crucial. Knowledge which is classified as explicit and tacit knowledge is the key element for any purpose. Tacit knowledge can be seen as "the tip of the iceberg”. This tacit knowledge accounts for much more than we guess in all intelligence cycle. If the concept of intelligence cycle is scrutinized, it can be seen that it contains risks, threats as well as success. The main purpose of all organizations is to be successful by eliminating risks and threats. Therefore, there is a need to connect or fuse existing information and the processes which can be used to develop it. Thanks to this process the decision-makers can be presented with a clear holistic understanding, as early as possible in the decision making process. Altering from the current traditional reactive approach to a proactive intelligence cycle approach would reduce extensive duplication of work in the organization. Applying new result-oriented cycle and tacit knowledge intelligence can be procured and utilized more effectively and timely. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=information" title="information">information</a>, <a href="https://publications.waset.org/abstracts/search?q=intelligence%20cycle" title=" intelligence cycle"> intelligence cycle</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge" title=" knowledge"> knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=tacit%20Knowledge" title=" tacit Knowledge"> tacit Knowledge</a> </p> <a href="https://publications.waset.org/abstracts/22694/the-effect-of-tacit-knowledge-for-intelligence-cycle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22694.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">514</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">3181</span> Using 'Know, Want to Know, Learned' Strategy to Enhance the Seventh C Grade Students' Reading Comprehension Achievement at SMPN 1 Mumbulsari </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Rofiq%20Badril%20Rizal%20M.%20Z.">Abdul Rofiq Badril Rizal M.

In this study, the Haptic Cycle is presented, a cycle of museum activities proposed for the development of museum learning approaches with optimized effectiveness and engagement. Haptic Cycle envisages the improvement of the museum’s services by offering a wide range of activities. Haptic Cycle activities make the museum’s exhibitions more approachable by bringing them closer to the visitors. Visitors can interact with the museum’s artifacts and explore them haptically and sonically. Haptic Cycle proposes constructivist learning activities in which visitors actively construct their knowledge by exploring the artifacts, experimenting with them and realizing their importance. Based on the Haptic Cycle, we developed the HapticSOUND system, an innovative virtual reality system that includes an advanced user interface that employs gesture-based technology. HapticSOUND’s interface utilizes the leap motion gesture recognition controller and a 3D-printed traditional Cretan lute, utilized by visitors to perform various activities such as exploring the lute and playing notes and songs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=haptic%20cycle" title="haptic cycle">haptic cycle</a>, <a href="https://publications.waset.org/abstracts/search?q=HapticSOUND" title=" HapticSOUND"> HapticSOUND</a>, <a href="https://publications.waset.org/abstracts/search?q=museum%20learning" title=" museum learning"> museum learning</a>, <a href="https://publications.waset.org/abstracts/search?q=gesture-based" title=" gesture-based"> gesture-based</a>, <a href="https://publications.waset.org/abstracts/search?q=leap%20motion" title=" leap motion"> leap motion</a> </p> <a href="https://publications.waset.org/abstracts/165300/haptic-cycle-designing-enhanced-museum-learning-activities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165300.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">91</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">3178</span> Thermodynamic Cycle Using Cyclopentane for Waste Heat Recovery Power Generation from Clinker Cooler Exhaust Flue Gas</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vijayakumar%20Kunche">Vijayakumar Kunche</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Waste heat recovery from Pre Heater exhaust gases and Clinker cooler vent gases is now common place in Cement Industry. Most common practice is to use Steam Rankine cycle for heat to power conversion. In this process, waste heat from the flue gas is recovered through a Heat Recovery steam generator where steam is generated and fed to a conventional Steam turbine generator. However steam Rankine cycle tends to have lesser efficiency for smaller power plants with less than 5MW capacity and where the steam temperature at the inlet of the turbine is less than 350 deg C. further a steam Rankine cycle needs treated water and maintenance intensive. These problems can be overcome by using Thermodynamic cycle using Cyclopentane vapour in place of steam. This innovative cycle is best suited for Heat recovery in cement plants and results in best possible heat to power conversion efficiency. This paper discusses about Heat Recovery Power generation using innovative thermal cycle which uses Cyclopentane vapour in place of water- steam.

Nini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Soil consolidation is one of the biggest problem facing engineers. The consolidation process has an important role in settlement analysis for the embankments and footings resting on clayey soils. The settlement amount is related to the compression and the swelling indexes of the soil. Because the predominant upper soil layer in Lebanon is consisting mainly of clay, this layer is a real challenge for structural and highway engineering. To determine the effect of load and drainage on the engineering consolidation characteristics of Lebanese soil, a full experimental and synthesis study was conducted on different soil samples collected from many locations. This study consists of two parts. During the first part which is an experimental one, the Proctor test and the consolidation test were performed on the collected soil samples. After it, the identifications soil tests as hydrometer, specific gravity and Atterberg limits are done. The consolidation test which is the main test in this research is done by loading the soil for some days then an unloading cycle was applied. It takes two weeks to complete a typical consolidation test. Because of these reasons, during the second part of our research which is based on the analysis of the experiments results, some correlations were found between the main consolidation parameters as compression and swelling indexes with the other soil parameters easy to calculate. The results show that the compression and swelling indexes of Lebanese clays may be roughly estimated using a model involving one or two variables in the form of the natural void ratio and the Atterberg limits. These correlations have increasing importance for site engineers, and the proposed model also seems to be applicable to a wide range of clays worldwide. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atterberg%20limits" title="atterberg limits">atterberg limits</a>, <a href="https://publications.waset.org/abstracts/search?q=clay" title=" clay"> clay</a>, <a href="https://publications.waset.org/abstracts/search?q=compression%20and%20swelling%20indexes" title=" compression and swelling indexes"> compression and swelling indexes</a>, <a href="https://publications.waset.org/abstracts/search?q=settlement" title=" settlement"> settlement</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20consolidation" title=" soil consolidation"> soil consolidation</a> </p> <a href="https://publications.waset.org/abstracts/108799/consolidation-behavior-of-lebanese-soil-and-its-correlation-with-the-soil-parameters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108799.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">137</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">3175</span> Life Cycle Assessment of Residential Buildings: A Case Study in Canada</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Venkatesh%20Kumar">Venkatesh Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Kasun%20Hewage"> Kasun Hewage</a>, <a href="https://publications.waset.org/abstracts/search?q=Rehan%20Sadiq"> Rehan Sadiq</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Residential buildings consume significant amounts of energy and produce a large amount of emissions and waste. However, there is a substantial potential for energy savings in this sector which needs to be evaluated over the life cycle of residential buildings. Life Cycle Assessment (LCA) methodology has been employed to study the primary energy uses and associated environmental impacts of different phases (i.e., product, construction, use, end of life, and beyond building life) for residential buildings. Four different alternatives of residential buildings in Vancouver (BC, Canada) with a 50-year lifespan have been evaluated, including High Rise Apartment (HRA), Low Rise Apartment (LRA), Single family Attached House (SAH), and Single family Detached House (SDH). Life cycle performance of the buildings is evaluated for embodied energy, embodied environmental impacts, operational energy, operational environmental impacts, total life-cycle energy, and total life cycle environmental impacts. Estimation of operational energy and LCA are performed using DesignBuilder software and Athena Impact estimator software respectively. The study results revealed that over the life span of the buildings, the relationship between the energy use and the environmental impacts are identical. LRA is found to be the best alternative in terms of embodied energy use and embodied environmental impacts; while, HRA showed the best life-cycle performance in terms of minimum energy use and environmental impacts. Sensitivity analysis has also been carried out to study the influence of building service lifespan over 50, 75, and 100 years on the relative significance of embodied energy and total life cycle energy. The life-cycle energy requirements for SDH is found to be a significant component among the four types of residential buildings. The overall disclose that the primary operations of these buildings accounts for 90% of the total life cycle energy which far outweighs minor differences in embodied effects between the buildings. <p
