wear prognosis of internal combustion engine plays an important role in the calculation efficiency and accuracy. In order to investigate the appropriate cycle index of the simplified working condition of wear simulation, the main bearing-crankshaft journal friction pair of a diesel engine in service was studied in this paper. The method of multi-body dynamics simulation was used, and the wear prognosis model of the main bearing was established. Several groups of cycle indexes were set up for the wear calculation, and the maximum wear depth and wear profile were compared and analyzed. The results showed that when the cycle index reaches 3, the maximum deviation rate of the maximum wear depth is about 2.8%, and the maximum deviation rate comes to 1.6% when the cycle index reaches 5. This study provides guidance and suggestions for the optimization of wear prognosis by selecting appropriate value of cycle index according to the requirement of calculation cost and accuracy of the simulation work. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cycle%20index" title="cycle index">cycle index</a>, <a href="https://publications.waset.org/abstracts/search?q=deviation%20rate" title=" deviation rate"> deviation rate</a>, <a href="https://publications.waset.org/abstracts/search?q=wear%20calculation" title=" wear calculation"> wear calculation</a>, <a href="https://publications.waset.org/abstracts/search?q=wear%20profile" title=" wear profile"> wear profile</a> </p> <a href="https://publications.waset.org/abstracts/108766/the-influence-of-cycle-index-of-simulation-condition-on-main-bearing-wear-prognosis-of-internal-combustion-engine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108766.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">168</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">5510</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">5509</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.

To solve the problem, “non-distressed”, “slightly-distressed” and “reorganization and bankruptcy” are used in our article to approximate the continuum of corporate financial health. This paper explains different financial distress events using the two-stage method. First, this investigation adopts firm-specific financial ratios, corporate governance and market factors to measure the probability of various financial distress events based on multinomial logit models. Specifically, the bootstrapping simulation is performed to examine the difference of estimated misclassifying cost (EMC). Second, this work further applies macroeconomic factors to establish the credit cycle index and determines the distressed cut-off indicator of the two-stage models using such index. Two different models, one-stage and two-stage prediction models, are developed to forecast financial distress, and the results acquired from different models are compared with each other, and with the collected data. The findings show that the two-stage model incorporating financial ratios, corporate governance and market factors has the lowest misclassification error rate. The two-stage model is more accurate than the one-stage model as its distressed cut-off indicators are adjusted according to the macroeconomic-based credit cycle index. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Multinomial%20logit%20model" title="Multinomial logit model">Multinomial logit model</a>, <a href="https://publications.waset.org/abstracts/search?q=corporate%20governance" title=" corporate governance"> corporate governance</a>, <a href="https://publications.waset.org/abstracts/search?q=company%20failure" title=" company failure"> company failure</a>, <a href="https://publications.waset.org/abstracts/search?q=reorganization" title=" reorganization"> reorganization</a>, <a href="https://publications.waset.org/abstracts/search?q=bankruptcy" title=" bankruptcy"> bankruptcy</a> </p> <a href="https://publications.waset.org/abstracts/23937/early-warning-system-of-financial-distress-based-on-credit-cycle-index" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23937.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">377</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">5507</span> Reliability-Based Life-Cycle Cost Model for Engineering Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reza%20Lotfalian">Reza Lotfalian</a>, <a href="https://publications.waset.org/abstracts/search?q=Sudarshan%20Martins"> Sudarshan Martins</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Radziszewski"> Peter Radziszewski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The effect of reliability on life-cycle cost, including initial and maintenance cost of a system is studied.

Aim: To find out the relationship between body mass composition and primary dysmenorrhea. Objectives: 1.To check whether there is any association between body mass index and primary dysmenorrhoea.2.To check whether there is any association between body fat percentage and primary dysmenorrhoea. NULL HYPOTHESES-There is no relationship between body mass composition and primary dysmenorrhea. Hypothesis: There exists a relationship between body mass composition and primary dysmenorrhea. Materials and Methods: The study was conducted over a period of 6 months with 90 samples selected on random basis. The procedure was explained to the participant and a written consent was taken thereafter. The participant was made to stand on the BODY COMPOSITION SCANNING MONITOR, which scanned the physical profile of the participant (height, weight, BMI, body fat percentage and visceral fat).Thereafter, the candidate was asked about her menstrual irregularities and was asked to grade her level of dysmenorrhoea (if present) using the Verbal Dimensional Dysmenorrhea Scale. Results: Chi square test of association was used to find out the association between body mass composition(body mass index,body fat percentage) and primary dysmenorrhea.The chi-square value for association between body mass index and primary dysmenorrhea was 38.63 p<0.001 which was statistically significant.The chi-square value for the association of body fat % & primary dysmenorrhea was 30.09,p<0.001which was statistically significant. Conclusion: Study shows that there exists a significant relationship between body mass composition and primary dysmenorrhea and as the value of Body mass index and body fat percentages goes on increasing in females, the severity of primary dysmenorrhea also increases. <p class="card-text"><strong>Keywords:</strong> <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=body%20composition%20screening%20monitor" title=" body composition screening monitor"> body composition screening monitor</a>, <a href="https://publications.waset.org/abstracts/search?q=primary%20dysmenorrhea" title=" primary dysmenorrhea"> primary dysmenorrhea</a>, <a href="https://publications.waset.org/abstracts/search?q=verbal%20dimensional%20dysmenorrhea%20scale" title=" verbal dimensional dysmenorrhea scale"> verbal dimensional dysmenorrhea scale</a> </p> <a href="https://publications.waset.org/abstracts/59337/relationship-between-body-mass-composition-and-primary-dysmenorrhoea" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59337.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">328</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">5504</span> Analysis of the Result for the Accelerated Life Cycle Test of the Motor for Washing Machine 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=Jin-Ho%20Jo"> Jin-Ho Jo</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> Accelerated life cycle test is applied to various products or components in order to reduce the time of life cycle test in industry.

The total electron content data has been observed with the help of Global Ionospheric Scintillation and TEC monitoring (GISTM) system installed at Indian permanent scientific 'Maitri station' [70˚46’00”S 11˚43’56” E]. The dependence of TEC over a solar cycle has been examined by the performing linear regression analysis between the vertical total electron content (VTEC) and daily total sunspot numbers (SSN). It has been found that the season and level of geomagnetic activity has a considerable effect on the VTEC. It is observed that the VTEC and SSN follow better agreement during summer seasons as compared to winter and equinox seasons and extraordinary agreement during minimum phase (during the year 2010) of the solar cycle. There is a significant correlation between VTEC and SSN during quiet days of the years as compared to overall days of the years (2010-2014). Further, saturation effect has been observed during maximum phase (during the year 2014) of the 24th solar cycle. It is also found that Ap index and SSN has a linear correlation (R=0.37) and the most of the geomagnetic activity occurs during the declining phase of the solar cycle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high%20latitude%20ionosphere" title="high latitude ionosphere">high latitude ionosphere</a>, <a href="https://publications.waset.org/abstracts/search?q=sunspot%20number" title=" sunspot number"> sunspot number</a>, <a href="https://publications.waset.org/abstracts/search?q=correlation" title=" correlation"> correlation</a>, <a href="https://publications.waset.org/abstracts/search?q=vertical%20total%20electron%20content" title=" vertical total electron content"> vertical total electron content</a> </p> <a href="https://publications.waset.org/abstracts/89867/variations-of-total-electron-content-over-high-latitude-region-during-the-24th-solar-cycle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89867.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">193</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">5501</span> A Further Study on the 4-Ordered Property of Some Chordal Ring Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shin-Shin%20Kao">Shin-Shin Kao</a>, <a href="https://publications.waset.org/abstracts/search?q=Hsiu-Chunj%20Pan"> Hsiu-Chunj Pan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Given a graph G. 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">5500</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">5498</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.

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">5496</span> Myoelectric Analysis for the Assessment of Muscle Functions and Fatigue Monitoring of Upper Extremity for Stroke Patients Performing Robot-Assisted Bilateral Training</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hsiao-Lung%20Chan">Hsiao-Lung Chan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ching-Yi%20Wu"> Ching-Yi Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yan-Zou%20Lin"> Yan-Zou Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Yo%20Chiao"> Yo Chiao</a>, <a href="https://publications.waset.org/abstracts/search?q=Ya-Ju%20Chang"> Ya-Ju Chang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Robot-assisted bilateral arm training has demonstrated useful to improve motor control in stroke patients and save human resources. In clinics, the efficiency of this treatment is mostly performed by comparing functional scales before and after rehabilitation. However, most of these assessments are based on behavior evaluation. The underlying improvement of muscle activation and coordination is unknown. Moreover, stroke patients are easier to have muscle fatigue under robot-assisted rehabilitation due to the weakness of muscles. This safety issue is still less studied. In this study, EMG analysis was applied during training. Our preliminary results showed the co-contraction index and co-contraction area index can delineate the improved muscle coordination of biceps brachii vs. flexor carpiradialis.

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">5493</span> Evaluating the Ability to Cycle in Cities Using Geographic Information Systems Tools: The Case Study of Greek Modern Cities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christos%20Karolemeas">Christos Karolemeas</a>, <a href="https://publications.waset.org/abstracts/search?q=Avgi%20Vassi"> Avgi Vassi</a>, <a href="https://publications.waset.org/abstracts/search?q=Georgia%20Christodoulopoulou"> Georgia Christodoulopoulou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although the past decades, planning a cycle network became an inseparable part of all transportation plans, there is still a lot of room for improvement in the way planning is made, in order to create safe and direct cycling networks that gather the parameters that positively influence one's decision to cycle. The aim of this article is to study, evaluate and visualize the bikeability of cities. This term is often used as the 'the ability of a person to bike' but this study, however, adopts the term in the sense of bikeability as 'the ability of the urban landscape to be biked'. The methodology used included assessing cities' accessibility by cycling, based on international literature and corresponding walkability methods and the creation of a 'bikeability index'. Initially, a literature review was made to identify the factors that positively affect the use of bicycle infrastructure. Those factors were used in order to create the spatial index and quantitatively compare the city network. Finally, the bikeability index was applied in two case studies: two Greek municipalities that, although, they have similarities in terms of land uses, population density and traffic congestion, they are totally different in terms of geomorphology. The factors suggested by international literature were (a) safety, (b) directness, (c) comfort and (d) the quality of the urban environment. Those factors were quantified through the following parameters: slope, junction density, traffic density, traffic speed, natural environment, built environment, activities coverage, centrality and accessibility to public transport stations. Each road section was graded for the above-mentioned parameters, and the overall grade shows the level of bicycle accessibility (low, medium, high). Each parameter, as well as the overall accessibility levels, were analyzed and visualized through Geographic Information Systems. This paper presents the bikeability index, its' results, the problems that have arisen and the conclusions from its' implementation through Strengths-Weaknesses-Opportunities-Threats analysis. The purpose of this index is to make it easy for researchers, practitioners, politicians, and stakeholders to quantify, visualize and understand which parts of the urban fabric are suitable for cycling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accessibility" title="accessibility">accessibility</a>, <a href="https://publications.waset.org/abstracts/search?q=cycling" title=" cycling"> cycling</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20spaces" title=" green spaces"> green spaces</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20data" title=" spatial data"> spatial data</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20environment" title=" urban environment"> urban environment</a> </p> <a href="https://publications.waset.org/abstracts/109008/evaluating-the-ability-to-cycle-in-cities-using-geographic-information-systems-tools-the-case-study-of-greek-modern-cities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109008.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">5492</span> A Comparative Study of Multi-SOM Algorithms for Determining the Optimal Number of Clusters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Im%C3%A8n%20Khanchouch">Imèn Khanchouch</a>, <a href="https://publications.waset.org/abstracts/search?q=Malika%20Charrad"> Malika Charrad</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Limam"> Mohamed Limam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The interpretation of the quality of clusters and the determination of the optimal number of clusters is still a crucial problem in clustering.

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">5490</span> Effect of Addition and Reduction of Sharia Index Constituents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rosyidah">Rosyidah</a>, <a href="https://publications.waset.org/abstracts/search?q=Permata%20Wulandari"> Permata Wulandari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We investigate the price effect of addition and deletions from the Indonesia Sharia Stock Index (ISSI) and Jakarta Islamic Index (JII).

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">5486</span> Exergetic and Life Cycle Assessment Analyses of Integrated Biowaste Gasification-Combustion System: A Study Case</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anabel%20Fernandez">Anabel Fernandez</a>, <a href="https://publications.waset.org/abstracts/search?q=Leandro%20Rodriguez-Ortiz"> Leandro Rodriguez-Ortiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Rosa%20Rodr%C3%ADGuez"> Rosa RodríGuez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the negative impact of fossil fuels, renewable energies are promising sources to limit global temperature rise and damage to the environment. Also, the development of technology is focused on obtaining energetic products from renewable sources. In this study, a thermodynamic model including Exergy balance and a subsequent Life Cycle Assessment (LCA) were carried out for four subsystems of the integrated gasification-combustion of pinewood. Results of exergy analysis and LCA showed the process feasibility in terms of exergy efficiency and global energy efficiency of the life cycle (GEELC). Moreover, the energy return on investment (EROI) index was calculated. The global exergy efficiency resulted in 67 %. For pretreatment, reaction, cleaning, and electric generation subsystems, the results were 85, 59, 87, and 29 %, respectively. Results of LCA indicated that the emissions from the electric generation caused the most damage to the atmosphere, water, and soil. GEELC resulted in 31.09 % for the global process. This result suggested the environmental feasibility of an integrated gasification-combustion system. EROI resulted in 3.15, which determinates the sustainability of the process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=exergy%20analysis" title="exergy analysis">exergy analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20cycle%20assessment%20%28LCA%29" title=" life cycle assessment (LCA)"> life cycle assessment (LCA)</a>, <a href="https://publications.waset.org/abstracts/search?q=renewability" title=" renewability"> renewability</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/139076/exergetic-and-life-cycle-assessment-analyses-of-integrated-biowaste-gasification-combustion-system-a-study-case" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139076.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">213</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">5485</span> Comparison of the H-Index of Researchers of Google Scholar and Scopus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adian%20Fatchur%20Rochim">Adian Fatchur Rochim</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Muis"> Abdul Muis</a>, <a href="https://publications.waset.org/abstracts/search?q=Riri%20Fitri%20Sari"> Riri Fitri Sari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> H-index has been widely used as a performance indicator of researchers around the world especially in Indonesia.

PURPOSE: The purpose of this research was to compare differences in upper and lower body maximal anaerobic capacities across a single menstrual cycle. Methode: Participants (n=11) met a total of four times; once for familiarization and again on day 1 of menses (follicular phase), day 14 (ovulation), and day 21 (luteal phase) respectively. Upper body power was assessed using a bench press weight of ~50% of the participant’s predetermined 1-repetition maximum (1-RM) on a ballistic measurement system and variables included peak force (N), mean force (N), peak power (W), mean power (W), and peak velocity (m/s). Lower body power output was collected using a standard Wingate test. The variables of interest were anaerobic capacity (w/kg), peak power (W), mean power (W), fatigue index (W/s), and total work (J). Result: Statistical significance was not observed (p > 0.05) in any of the aforementioned variables after completing multiple one ways of analyses of variances (ANOVAs) with repeated measures on time. Conclusion: Within the parameters of this research, neither female upper nor lower body power output differed across the menstrual cycle when analyzed using 50% of one repetition (1RM) maximal bench press and the 30-second maximal effort cycle ergometer Wingate test. Therefore, researchers should not alter their subject populations due to the incorrect assumption that power output may be influenced by the menstrual cycle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anaerobic" title="anaerobic">anaerobic</a>, <a href="https://publications.waset.org/abstracts/search?q=athlete" title=" athlete"> athlete</a>, <a href="https://publications.waset.org/abstracts/search?q=female" title=" female"> female</a>, <a href="https://publications.waset.org/abstracts/search?q=power" title=" power"> power</a> </p> <a href="https://publications.waset.org/abstracts/93962/the-effects-of-menstrual-phase-on-upper-and-lower-body-anaerobic-performance-in-college-aged-women" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93962.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">146</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">5483</span> Energy Efficiency Index Applied to Reactive Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20G%C3%B3es">P.

Among the requirements of such energy efficiency index, the practical feasibility must be essential. To illustrate the performance of the proposed index, such an index was used as decisive factor of evaluation for the optimization process of an industrial reactor. The results allow the conclusion to be drawn that the energy efficiency index applied to the reactive system is consistent because it extracts the information expected of an efficient indicator, and that it is useful as an analytical tool besides being feasible from a practical standpoint. Furthermore, it has proved to be much simpler to use than tools based on traditional methodologies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy" title="energy">energy</a>, <a href="https://publications.waset.org/abstracts/search?q=efficiency" title=" efficiency"> efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=entropy" title=" entropy"> entropy</a>, <a href="https://publications.waset.org/abstracts/search?q=reactive" title=" reactive"> reactive</a> </p> <a href="https://publications.waset.org/abstracts/45768/energy-efficiency-index-applied-to-reactive-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45768.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">411</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">5482</span> An Efficiency Measurement of E-Government Performance for United Nation Ranking Index</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yassine%20Jadi">Yassine Jadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Lin%20Jie"> Lin Jie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to serve the society in an electronic manner, many developing countries have launched tremendous e-government projects. The strategies of development and implementation e-government system have reached different levels, and to ensure consistency of development, the governments need to evaluate e-government performance. The United nation has design e-government development ranking index (EGDI) that rely on three indexes, Online service index (OSI), Telecommunication Infrastructure index (TII), and human capital index( HCI) which are not reflecting the interaction between a government and their citizens. Based on data envelopment analyses (DEA) technique, we are using E-participating index (EPI) as an output of government effort to evaluate the performance of e-government system. Therefore, the ranking index can be achieved in efficiency manner. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=e-government"
