</p> <p class="card-text"><strong>Abstract:</strong></p> We study the period change of six Cepheids using 19376 accurate flux observations of the Solar Mass Ejection Imager (SMEI) onboard the Coriolis spacecraft. All observations for the six Cepheids have been derived as templates for each star, independent of the specific sites utilized to establish and update the O-C values. Sometimes, sinusoidal patterns are superimposed on the star's O-C changes, which cannot be regarded as random fluctuations in the pulsation period. Random period changes were detected and computed using Eddington's and Plakidis's approaches. A comparison of the observed and predicted period change reveals a good agreement with some published models and a very substantial divergence with others. Between the reported period change and that estimated by the current technique, a linear fit with a correlation coefficient of 90.08 percent was obtained. The temporal rate of period change in Cepheid stars might be connected to how well these stars' mass losses are known today. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cepheids" title="cepheids">cepheids</a>, <a href="https://publications.waset.org/abstracts/search?q=period%20change" title=" period change"> period change</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20loss" title=" mass loss"> mass loss</a>, <a href="https://publications.waset.org/abstracts/search?q=O-C%20changes" title=" O-C changes"> O-C changes</a>, <a href="https://publications.waset.org/abstracts/search?q=period%20change" title=" period change"> period change</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20loss" title=" mass loss"> mass loss</a>, <a href="https://publications.waset.org/abstracts/search?q=O-C" title=" O-C"> O-C</a> </p> <a href="https://publications.waset.org/abstracts/187496/study-of-changes-in-the-pulsation-period-of-six-cepheid-variables" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187496.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">41</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">5638</span> A Study of Two Disease Models: With and Without Incubation Period</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20C.%20Chinwenyi">H.

In this research, two disease models: one with incubation period and another without incubation period were studied. The study involves the use of a  mathematical model with a single incubation period. The test for the existence and stability of the disease free and the endemic equilibrium states for both models were carried out. The fourth order Runge-Kutta method was used to solve both models numerically. Finally, a computer program in MATLAB was developed to run the numerical experiments. From the results, we are able to show that the endemic equilibrium state of the model with incubation period is locally asymptotically stable whereas the endemic equilibrium state of the model without incubation period is unstable under certain conditions on the given model parameters. It was also established that the disease free equilibrium states of the model with and without incubation period are locally asymptotically stable. Furthermore, results from numerical experiments using empirical data obtained from Nigeria Centre for Disease Control (NCDC) showed that the overall population of the infected people for the model with incubation period is higher than that without incubation period. We also established from the results obtained that as the transmission rate from susceptible to infected population increases, the peak values of the infected population for the model with incubation period decrease and are always less than those for the model without incubation period. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asymptotic%20stability" title="asymptotic stability">asymptotic stability</a>, <a href="https://publications.waset.org/abstracts/search?q=Hartman-Grobman%20stability%20criterion" title=" Hartman-Grobman stability criterion"> Hartman-Grobman stability criterion</a>, <a href="https://publications.waset.org/abstracts/search?q=incubation%20period" title=" incubation period"> incubation period</a>, <a href="https://publications.waset.org/abstracts/search?q=Routh-Hurwitz%20criterion" title=" Routh-Hurwitz criterion"> Routh-Hurwitz criterion</a>, <a href="https://publications.waset.org/abstracts/search?q=Runge-Kutta%20method" title=" Runge-Kutta method"> Runge-Kutta method</a> </p> <a href="https://publications.waset.org/abstracts/92942/a-study-of-two-disease-models-with-and-without-incubation-period" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92942.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">175</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">5637</span> Multi-Period Portfolio Optimization Using Predictive Machine Learning Models</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Peng%20Liu">Peng Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Chyng%20Wen%20Tee"> Chyng Wen Tee</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaofei%20Xu"> Xiaofei Xu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper integrates machine learning forecasting techniques into the multi-period portfolio optimization framework, enabling dynamic asset allocation based on multiple future periods.

The basic period approach is effective for solving the ELSP. The assumption for applying the basic period approach is that a product must use its maximum production rate to be produced. However, a product can lower its production rate to reduce the average total cost when a facility has extra idle time. The past researches discussed how a product adjusts its production rate under the common cycle approach. To the best of our knowledge, no studies have addressed how a product lowers its production rate under the basic period approach. This research is the first paper to discuss this topic. The research develops a simple fixed rate approach that adjusts the production rate of a product under the basic period approach to solve the ELSP. Our numerical example shows our approach can find a better solution than the traditional basic period approach. Our mathematical model that applies the fixed rate approach under the basic period approach can serve as a reference for other related researches. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=economic%20lot" title="economic lot">economic lot</a>, <a href="https://publications.waset.org/abstracts/search?q=basic%20period" title=" basic period"> basic period</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title=" genetic algorithm"> genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=fixed%20rate" title=" fixed rate"> fixed rate</a> </p> <a href="https://publications.waset.org/abstracts/28582/using-the-simple-fixed-rate-approach-to-solve-economic-lot-scheduling-problem-under-the-basic-period-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28582.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">563</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">5635</span> An Artistic Study of Three Rare Tennded Copper Dishes from the Mamluk Circassian Period (784- 923 AH/ 1382- 1517 CE)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tamer%20Mokhtar%20Mohamed%20Ahmed">Tamer Mokhtar Mohamed Ahmed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The metalwork industry during the Mamluk period received the attention and care of the sultans and princes, thus helping in the prosperity of this industry during this period. We are fortunate that a huge number of metal artifacts from the industry of Egypt and Syria of this period have come down to us, many of which are preserved in Egyptian and international museums as well as private collections. Characterized by great diversity in its forms, sizes and functions, including the decorative designs executed on them, the artifacts reflected the extent of artistic creativity that characterized the arts in the two Mamluk period. This research paper aims to study three copper dishes from the Mamluk Circassian period and the rare documentary texts on them that have not been previously studied. These dishes date back to different decades from the 9th AH/15 AD century. One of them bears the name of Sultan Al-Muayyad Shaikh, and the second is the name of one of the great Mamluk princes in the Mamluk Circassian period, Prince Yashbak min Mahdi.

A methodology adapted to the specific context of the city is proposed and applied in order to assess and extract results related to the climate analysis of the city of Athens, the general/architectural design and construction characteristics of the apartment buildings constructed during the period 1920 – 1960, the bioclimatic strategies applied on them, and the achieved thermal comfort based on questionnaires answered by their users. The results of the current study indicate that the residential architecture of that period in the city of Athens is adapted to an extend to the local climate with various climate responsive strategies. As an outcome of the analysis, the most frequently applied depending on the period of construction are presented. For this reason, the examined period is divided into 3 sub – periods: 1st period 1920s – 1930s (late neoclassicism & eclecticism), 2nd period 1930s – 1940s (modernism), 3rd period 1940s – 1960s (postwar modernism). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Athens" title="Athens">Athens</a>, <a href="https://publications.waset.org/abstracts/search?q=climatic%20design%20strategies" title=" climatic design strategies"> climatic design strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=residential%20buildings" title=" residential buildings"> residential buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=middle%20war%20and%20post%20war%20architecture" title=" middle war and post war architecture"> middle war and post war architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20comfort" title=" thermal comfort"> thermal comfort</a> </p> <a href="https://publications.waset.org/abstracts/152111/an-investigation-on-climate-responsive-design-strategies-of-apartment-buildings-in-athens-of-the-period-1920-1960s" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152111.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">102</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">5633</span> Nonlinear Heat Transfer in a Spiral Fin with a Period Base Temperature</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kuo-Teng%20Tsai">Kuo-Teng Tsai</a>, <a href="https://publications.waset.org/abstracts/search?q=You-Min%20Huang"> You-Min Huang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the problem of a spiral fin with a period base temperature is analyzed by using the Adomian decomposition method.

The data that are used to test if there is any change in the KSE market performance are the daily indices for the period from the 25th of April 2016 till the 24th of October 2016 (after privatization) and a similar six months period before the date of the privatization from the 24th of October 2015 till the 24th of April 2016. In addition, as a control, the study included a period that is a period parallel to the six months period after the privatization. The results indicate that privatization is associated with lower variability for the majority of variables, but that the observed switch in slope direction is not actually a product of privatization, but rather one of serial correlation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=privatization" title="privatization">privatization</a>, <a href="https://publications.waset.org/abstracts/search?q=Kuwait%20stock%20exchange%20%28KSE%29" title=" Kuwait stock exchange (KSE)"> Kuwait stock exchange (KSE)</a>, <a href="https://publications.waset.org/abstracts/search?q=market%20capitalization%20%28MCAP%29" title=" market capitalization (MCAP)"> market capitalization (MCAP)</a>, <a href="https://publications.waset.org/abstracts/search?q=capital%20markets%20authority%20%28CMA%29" title=" capital markets authority (CMA)"> capital markets authority (CMA)</a>, <a href="https://publications.waset.org/abstracts/search?q=Boursa%20Kuwait%20securities%20company%20%28BKSC%29" title=" Boursa Kuwait securities company (BKSC)"> Boursa Kuwait securities company (BKSC)</a> </p> <a href="https://publications.waset.org/abstracts/62593/measuring-the-effect-of-the-privatization-of-the-kuwait-stock-exchange-on-its-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62593.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">5631</span> Body Weight Variation in Indian Heterogeneous Group-An Analytical Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20K.%20Srivastva">A.

Total 7500 samples pooled from ten Indian states ranging in their age 15 to 20 years were examined in six age categories. Conclusion: 1. The period between 15 to 20 year of age is a growing period and that body weight is gained during this period. 2. Statewise difference is observed in body-weight during the period, which is significant. 3. PRG indicated by higher rate of weight gain varies from state to state. 4. Sportsman possess comparatively higer level of body-weight than other student of same age group. 5. Tribal youths show comparatively better status in their weight gain than the untrained uraban dwellers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PRG%20%28period%20of%20rapid%20growth%29" title="PRG (period of rapid growth)">PRG (period of rapid growth)</a>, <a href="https://publications.waset.org/abstracts/search?q=HG%20%28heterogeneous%20group%29" title=" HG (heterogeneous group)"> HG (heterogeneous group)</a>, <a href="https://publications.waset.org/abstracts/search?q=WP%20%28weight%20pattern%29" title=" WP (weight pattern)"> WP (weight pattern)</a>, <a href="https://publications.waset.org/abstracts/search?q=MBW%20%28mean%20body%20weight%29" title=" MBW (mean body weight)"> MBW (mean body weight)</a> </p> <a href="https://publications.waset.org/abstracts/39375/body-weight-variation-in-indian-heterogeneous-group-an-analytical-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39375.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">337</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">5630</span> Assessment of Collapse Potential of Degrading SDOF Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muzaffer%20Borekci">Muzaffer Borekci</a>, <a href="https://publications.waset.org/abstracts/search?q=Murat%20Serdar%20Kir%C3%A7il"> Murat Serdar Kirçil</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Predicting the collapse potential of a structure during earthquakes is an important issue in earthquake engineering. Many researchers proposed different methods to assess the collapse potential of structures under the effect of strong ground motions.

In this study, collapse potential of SDOF systems caused by dynamic instability with stiffness and strength degradation has been investigated. An equation was proposed for the estimation of collapse period of SDOF system which is a limit value of period for dynamic instability. If period of the considered SDOF system is shorter than the collapse period then the relevant system exhibits dynamic instability and collapse occurs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=collapse" title="collapse">collapse</a>, <a href="https://publications.waset.org/abstracts/search?q=degradation" title=" degradation"> degradation</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20instability" title=" dynamic instability"> dynamic instability</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20response" title=" seismic response "> seismic response </a> </p> <a href="https://publications.waset.org/abstracts/19772/assessment-of-collapse-potential-of-degrading-sdof-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19772.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">378</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">5629</span> Ultrasonic Densitometry of Alveolar Bone Jaw during Retention Period of Orthodontic Treatment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Margarita%20A.%20Belousova">Margarita A.

The first part of the research introduces period poverty and the lack of sustainable options currently in place to resolve the issue. The second part delves into a comparison of existing technologies – single-use and reusable period products -- and their benefits and deficiencies. It also provides a comparison of two countries and their existing solutions landscape (Scotland and the United States), arguing that while Scotland has provided an innovative national solution to the problem, it still lacks a proper assessment of the issue of sustainability, while the United States continues to lag in offering any holistic solution at all.

Nini </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The quality of road pavement is affected mostly by the type of sub-grade which is acting as road foundation. The roads degradation is related to many factors especially the climatic conditions, the quality, and the thickness of the base materials. The thickness of this layer depends on its California Bearing Ratio (CBR) test value which by its turn is highly affected by the quantity of water infiltrated under the road after heavy rain. The capacity of the base material to drain out its water is predominant factor because any change in moisture content causes change in sub-grade strength. This paper studies the effect of the soaking period of soil especially clay on its CBR value. For this reason, we collected many clayey samples in order to study the effect of the soaking period on its CBR value. On each soil, two groups of experiments were performed: main tests consisting of Proctor and CBR test from one side and from other side identification tests consisting of other tests such as Atterberg limits tests. Each soil sample was first subjected to Proctor test in order to find its optimum moisture content which will be used to perform the CBR test. Four CBR tests were performed on each soil with different soaking period. The first CBR was done without soaking the soil sample; the second one with two days soaking, the third one with four days soaking period and the last one was done under eight days soaking. By comparing the results of CBR tests performed with different soaking time, a more detailed understanding was given to the role of the water in reducing the CBR of soil. In fact, by extending the soaking period, the CBR was found to be reduced quickly the first two days and slower after. A precise reduction factor of the CBR in relation with soaking period was found at the end of this paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=California%20Bearing%20Ratio" title="California Bearing Ratio">California Bearing Ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=clay" title=" clay"> clay</a>, <a href="https://publications.waset.org/abstracts/search?q=proctor%20test" title=" proctor test"> proctor test</a>, <a href="https://publications.waset.org/abstracts/search?q=soaking%20period" title=" soaking period"> soaking period</a>, <a href="https://publications.waset.org/abstracts/search?q=sub-grade" title=" sub-grade"> sub-grade</a> </p> <a href="https://publications.waset.org/abstracts/98889/effect-of-soaking-period-of-clay-on-its-california-bearing-ratio-value" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98889.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">132</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">5623</span> Seismic Base Shear Force Depending on Building Fundamental Period and Site Conditions: Deterministic Formulation and Probabilistic Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Dorbani">S.

These structures are erected at different epicentral distances. Using the Boumerdes, Algeria (2003) earthquake data, we focused primarily on the establishment of the deterministic formulation linking the base shear force to two parameters: The first one is the fundamental period that represents the numerical fingerprint of the structure, and the second one is the epicentral distance used to represent the impact of the earthquake on this force. In a second step, with a view to highlight the effect of uncertainty in these parameters on the analyzed response, these parameters are modeled as random variables with a log-normal distribution. The variability of the coefficients of variation of the chosen uncertain parameters, on the statistics on the seismic base shear force, showed that the effect of uncertainty on fundamental period on this force statistics is low compared to the epicentral distance uncertainty influence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=base%20shear%20force" title="base shear force">base shear force</a>, <a href="https://publications.waset.org/abstracts/search?q=fundamental%20period" title=" fundamental period"> fundamental period</a>, <a href="https://publications.waset.org/abstracts/search?q=epicentral%20distance" title=" epicentral distance"> epicentral distance</a>, <a href="https://publications.waset.org/abstracts/search?q=uncertainty" title=" uncertainty"> uncertainty</a>, <a href="https://publications.waset.org/abstracts/search?q=lognormal%20variables" title=" lognormal variables"> lognormal variables</a>, <a href="https://publications.waset.org/abstracts/search?q=statistics" title=" statistics"> statistics</a> </p> <a href="https://publications.waset.org/abstracts/59431/seismic-base-shear-force-depending-on-building-fundamental-period-and-site-conditions-deterministic-formulation-and-probabilistic-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59431.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">320</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">5622</span> Joint Optimal Pricing and Lot-Sizing Decisions for an Advance Sales System under Stochastic Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Ghoreishi">Maryam Ghoreishi</a>, <a href="https://publications.waset.org/abstracts/search?q=Christian%20Larsen"> Christian Larsen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we investigate the effect of stochastic inputs on problem of joint optimal pricing and lot-sizing decisions where the inventory cycle is divided into advance and spot sales periods. During the advance sales period, customer can make reservations while customer with reservations can cancel their order. However, during the spot sales period customers receive the order as soon as the order is placed, but they cannot make any reservation or cancellation during that period. We assume that the inter arrival times during the advance sales and spot sales period are exponentially distributed where the arrival rate is decreasing function of price. Moreover, we assume that the number of cancelled reservations is binomially distributed. In addition, we assume that deterioration process follows an exponential distribution. We investigate two cases. First, we consider two-state case where we find the optimal price during the spot sales period and the optimal price during the advance sales period. Next, we develop a generalized case where we extend two-state case also to allow dynamic prices during the spot sales period. We apply the Markov decision theory in order to find the optimal solutions. In addition, for the generalized case, we apply the policy iteration algorithm in order to find the optimal prices, the optimal lot-size and maximum advance sales amount. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inventory%20control" title="inventory control">inventory control</a>, <a href="https://publications.waset.org/abstracts/search?q=pricing" title=" pricing"> pricing</a>, <a href="https://publications.waset.org/abstracts/search?q=Markov%20decision%20theory" title=" Markov decision theory"> Markov decision theory</a>, <a href="https://publications.waset.org/abstracts/search?q=advance%20sales%20system" title=" advance sales system"> advance sales system</a> </p> <a href="https://publications.waset.org/abstracts/83282/joint-optimal-pricing-and-lot-sizing-decisions-for-an-advance-sales-system-under-stochastic-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83282.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">324</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">5621</span> Seismic Evaluation of Reinforced Concrete Buildings in Myanmar, Based on Microtremor Measurement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khaing%20Su%20Su%20Than">Khaing Su Su Than</a>, <a href="https://publications.waset.org/abstracts/search?q=Hibino%20Yo"> Hibino Yo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Seismic evaluation is needed upon the buildings in Myanmar. Microtremor measurement was conducted in the main cities, Mandalay and Yangon. In order to evaluate the seismic properties of buildings currently under construction, seismic information was gathered for six buildings in Yangon city and four buildings in Mandalay city. The investigated buildings vary from 12m-80 m in height, and mostly public residence structures. The predominant period obtained from frequency results of the investigated buildings were given by horizontal to vertical spectral ratio (HVSR) for each building. The fundamental period results have been calculated in the form of Fourier amplitude spectra of translation along with the main structure. Based on that, the height (H)-period(T) relationship was observed as T=0.012H-0.017H in the buildings of Yangon and, observed the relationship as T=0.014H-0.019H in the buildings of Mandalay. The results showed that the relationship between height and natural period was slightly under the relationship T=0.02H that is used for Japanese reinforced concrete buildings, which indicated that the results depend on the properties and characteristics of materials used. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HVSR" title="HVSR">HVSR</a>, <a href="https://publications.waset.org/abstracts/search?q=height-period%20relationship" title=" height-period relationship"> height-period relationship</a>, <a href="https://publications.waset.org/abstracts/search?q=microtremor" title=" microtremor"> microtremor</a>, <a href="https://publications.waset.org/abstracts/search?q=Myanmar%20earthquake" title=" Myanmar earthquake"> Myanmar earthquake</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20concrete%20structures" title=" reinforced concrete structures"> reinforced concrete structures</a> </p> <a href="https://publications.waset.org/abstracts/110356/seismic-evaluation-of-reinforced-concrete-buildings-in-myanmar-based-on-microtremor-measurement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110356.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">157</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">5620</span> A Study on the Treatment of Municipal Waste Water Using Sequencing Batch Reactor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bhaven%20N.%20Tandel">Bhaven N.

All sequencing batch reactor systems have five steps in common, which are carried out in sequence as follows, (1) fill (2) react (3) settle (sedimentation/clarification) (4) draw (decant) and (5) idle. The study was carried out in a sequencing batch reactor of dimensions 44cmx30cmx70cm with a working volume of 40 L. Mechanical stirrer of 100 rpm was used to provide continuous mixing in the react period and oxygen was supplied by fish tank aerators. The duration of a complete cycle of sequencing batch reactor was 8 hours. The cycle period was divided into different phases in sequence as follows-0.25 hours fill phase, 6 hours react period, 1 hour settling phase, 0.5 hours decant period and 0.25 hours idle phase. The study consisted of two runs, run 1 and run 2. Run 1 consisted of 6 hours aerobic react period and run 2 consisted of 3 hours aerobic react period followed by 3 hours anoxic react period. The influent wastewater used for the study had COD, BOD, NH3-N and TKN concentrations of 308.03±48.94 mg/L, 100.36±22.05 mg/L, 14.12±1.18 mg/L, and 24.72±2.21 mg/L respectively. Run 1 had an average COD removal efficiency of 41.28%, BOD removal efficiency of 56.25%, NH3-N removal efficiency of 86.19% and TKN removal efficiency of 54.4%. Run 2 had an average COD removal efficiency of 63.19%, BOD removal efficiency of 73.85%, NH3-N removal efficiency of 90.74% and TKN removal efficiency of 65.25%. It was observed that run 2 gave better performance than run 1 in the removal of COD, BOD and TKN. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=municipal%20waste%20water" title="municipal waste water">municipal waste water</a>, <a href="https://publications.waset.org/abstracts/search?q=aerobic" title=" aerobic"> aerobic</a>, <a href="https://publications.waset.org/abstracts/search?q=anoxic" title=" anoxic"> anoxic</a>, <a href="https://publications.waset.org/abstracts/search?q=sequencing%20batch%20reactor" title=" sequencing batch reactor"> sequencing batch reactor</a> </p> <a href="https://publications.waset.org/abstracts/34727/a-study-on-the-treatment-of-municipal-waste-water-using-sequencing-batch-reactor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34727.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">550</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">5619</span> Seismic Hazard Study and Strong Ground Motion in Southwest Alborz, Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fereshteh%20Pourmohammad">Fereshteh Pourmohammad</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Zare"> Mehdi Zare</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The city of Karaj, having a population of 2.2 millions (est. 2022) is located in the South West of Alborz Mountain Belt in Northern Iran. The region is known to be a highly active seismic zone. This study is focused on the geological and seismological analyses within a radius of 200 km from the center of Karaj. There are identified five seismic zones and seven linear seismic sources. The maximum magnitude was calculated for the seismic zones. Scine tghe seismicity catalog is incomplete, we have used a parametric-historic algorithm and the Kijko and Sellevoll (1992) method was used to calculate seismicity parameters, and the return periods and the probability frequency of recurrence of the earthquake magnitude in each zone obtained for 475-years return period. According to the calculations, the highest and lowest earthquake magnitudes of 7.6 and 6.2 were respectively obtained in Zones 1 and 4. This result is a new and extremely important in view point of earthquake risk in a densely population city. The maximum strong horizontal ground motion for the 475-years return period 0.42g and for 2475-year return period 0.70g also the maximum strong vertical ground motion for 475-years return period 0.25g and 2475-years return period 0.44g was calculated using attenuation relationships. These acceleration levels are new, and are obtained to be about 25% higher than presented values in the Iranian building code. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=seismic%20zones" title="seismic zones">seismic zones</a>, <a href="https://publications.waset.org/abstracts/search?q=ground%20motion" title=" ground motion"> ground motion</a>, <a href="https://publications.waset.org/abstracts/search?q=return%20period" title=" return period"> return period</a>, <a href="https://publications.waset.org/abstracts/search?q=hazard%20analysis" title=" hazard analysis"> hazard analysis</a> </p> <a href="https://publications.waset.org/abstracts/157805/seismic-hazard-study-and-strong-ground-motion-in-southwest-alborz-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157805.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">97</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">5618</span> A Cohort and Empirical Based Multivariate Mortality Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeffrey%20Tzu-Hao%20Tsai">Jeffrey Tzu-Hao Tsai</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi-Shan%20Wong"> Yi-Shan Wong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article proposes a cohort-age-period (CAP) model to characterize multi-population mortality processes using cohort, age, and period variables.

The model not only provides a fruitful intuition for explaining multivariate mortality change rates but also has a better performance in forecasting future patterns.

In the government control period in the 1970s, environmental problems in U.S. are treated by mandatory direct control method, including promulgation of laws, formulation of emission standards and mandatory installation of pollution treatment equipment. After the 1980s, the environmental policy in U.S. went into the second stage, in which the government strengthened the incentives and coordination effects of market. Since then, environmental governance had been partially replaced by means of economic regulation of the market. Green Tax Policy and Marketable Pollution Permits are good examples of government's economic interventions. U.S. Federal Government regards environmental industry as high-tech industry which is promoted in this period. Therefore, in the paper, we aim to analyse the effect of environmental investment on the sustainable development in the US.

There is, therefore, the need to increase agricultural production and other forest products to ensure food security and economic development. This paper employs the three-level intensity analysis to assess the total change of land-use in two-time intervals (1986-2002 and 2002-2017), the net change and swap as well as gross gains and losses in the two intervals. The results revealed that the overall change in the 31-year period was greater in the second period (2002-2017). Agriculture and forest categories lost in the first period while the other land class gained. However, in the second period agriculture and built-up increased greatly while forest, water bodies and thick bushes/shrubland experienced loss. An assessment revealed a reduction of forest in both periods but was greater in the second period and expansion of agricultural land was recorded as population increases. The pixels gaining built-up targeted agricultural land in both intervals, it also targeted thick bushes/shrubland and waterbody in the second period only. Built-up avoided forest in both intervals as well as waterbody and thick bushes/shrubland. To help in developing the best land-use strategies/policies, a further validation of the social factors is necessary. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agricultural%20land" title="agricultural land">agricultural land</a>, <a href="https://publications.waset.org/abstracts/search?q=forest" title=" forest"> forest</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghana" title=" Ghana"> Ghana</a>, <a href="https://publications.waset.org/abstracts/search?q=land-use" title=" land-use"> land-use</a>, <a href="https://publications.waset.org/abstracts/search?q=intensity%20analysis" title=" intensity analysis"> intensity analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=remote%20sensing" title=" remote sensing"> remote sensing</a> </p> <a href="https://publications.waset.org/abstracts/125724/intensity-analysis-to-link-changes-in-land-use-pattern-in-the-abuakwa-north-and-south-municipalities-ghana-from-1986-to-2017" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125724.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">154</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">5614</span> Nazi Experiments during World War II: Dismal Period for Bioethics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Catharina%20O.%20Vianna%20Dias%20da%20Silva">Catharina O.

The method was based on the bibliographic review of articles published in databases such as SciELO and Pubmed. In the discussion, historical and humanistic aspects that contributed to the construction of a genocidal culture practiced during this period were analyzed. Additionally, an ethical question arises: should the information acquired during this dark period be used by science? After analysis, it was found that these Nazi experiments went over medical and ethical principles, being a deplorable milestone in history. It was also concluded that, although they generated potentially 'useful' results in the scientific field, they should be discarded as an ethical question of principle, of never daring to validate such a deplorable way of obtaining knowledge. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nazism" title="Nazism">Nazism</a>, <a href="https://publications.waset.org/abstracts/search?q=bioethics" title=" bioethics"> bioethics</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20experimentation" title=" human experimentation"> human experimentation</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20rights" title=" human rights"> human rights</a>, <a href="https://publications.waset.org/abstracts/search?q=genocide" title=" genocide"> genocide</a>, <a href="https://publications.waset.org/abstracts/search?q=torture" title=" torture"> torture</a>, <a href="https://publications.waset.org/abstracts/search?q=medicine" title=" medicine"> medicine</a> </p> <a href="https://publications.waset.org/abstracts/133246/nazi-experiments-during-world-war-ii-dismal-period-for-bioethics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133246.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">172</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">5613</span> Impact of Natural Period and Epicentral Distance on Storey Lateral Displacements</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saida%20Dorbani">Saida Dorbani</a>, <a href="https://publications.waset.org/abstracts/search?q=M%27hammed%20Badaoui"> M'hammed Badaoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Djilali%20Benouar"> Djilali Benouar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper deals with the effect of the building design and epicentral distance on the storey lateral displacement, for several reinforced concrete buildings (6, 9 and 12 stories), with three floor plans: symmetric, mono symmetric, and unsymmetrical.

Although the transition from the prenatal period to the postnatal period is usually desired and planned, it is a developmental and cognitive transition period full of complex emotional reactions. During this period, common mood disorders for women include maternity blues, postpartum depression and postpartum psychosis. Postpartum depression is a common and serious mood disorder which can jeopardize the health of the mother, baby and family within the first year of delivery. Knowing the risks factors is an important issue for the early detection and early intervention of postpartum depression. However, knowing that a history of infertility may contribute to the development of postpartum depression, there are few studies assessing the effects of infertility during the diagnosis and treatment of depression. In this review, the effects of infertility on the development of postpartum depression and nurse/midwives’ roles in this issue are discussed in light with the literature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=infertility" title="infertility">infertility</a>, <a href="https://publications.waset.org/abstracts/search?q=postpartum%20depression" title=" postpartum depression"> postpartum depression</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20factors" title=" risk factors"> risk factors</a>, <a href="https://publications.waset.org/abstracts/search?q=mood%20disorder" title=" mood disorder"> mood disorder</a> </p> <a href="https://publications.waset.org/abstracts/16773/an-under-recognized-factor-in-the-development-of-postpartum-depression-infertility" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16773.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">478</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">5611</span> Comparative Study of Poetics of Ancient China and Greece</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Junwu%20Tian">Junwu Tian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Chinese poetics originated in the pre-Qin period, while Western poetics came into being in the Hellenistic period. Although there was no mutual communication and influence between the two kinds of poetics due to both geographical distance and chronological displacement, the Sino-Western thinkers shared much in common, particularly in the social function of literature and art, the pursuit of unified and harmonious aesthetics, the advocacy of poets’ subjective initiative in the creative process of literature and art. In the sphere of rhetoric, the poetics of the pre-Qin scholars and their Greek counterparts also had heterogeneous similarities. By comparing the aesthetic ideas of Confucius, Mencius, Xun Zi, and Deng Xi with those of Plato, Aristotle, and Protagoras, this paper intends to reveal the common concerns of Chinese and Western poetics in the context of heterogeneous cultures and in their respective origin periods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pre-Qin%20poetics" title="Pre-Qin poetics">Pre-Qin poetics</a>, <a href="https://publications.waset.org/abstracts/search?q=ancient%20Greek%20poetics" title=" ancient Greek poetics"> ancient Greek poetics</a>, <a href="https://publications.waset.org/abstracts/search?q=heterogeneous%20similarity" title=" heterogeneous similarity"> heterogeneous similarity</a>, <a href="https://publications.waset.org/abstracts/search?q=origin%20period" title=" origin period"> origin period</a> </p> <a href="https://publications.waset.org/abstracts/167723/comparative-study-of-poetics-of-ancient-china-and-greece" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167723.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">80</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">5610</span> Intestinal Epithelium of Juvenile Dourado (Salminus brasiliensis) Fed with Bovine Colostrum</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thaline%20Maira%20P.%20Cruz">Thaline Maira P.

Juveniles were fed with diets containing 0, 10 or 20% of lyophilized bovine colostrum (LBC) inclusion for either 30 or 60 days. For the histological study, the intestine was divided into three segments, S1, S2 and posterior intestine. In the S1 segment, interaction between treatment and period was observed in the number of goblet cells containing sialomucin, effect of treatment in the total number of goblet cells and effect of period in the number of goblet cells containing sulphomucins (P<0.05). In the S2 segment, effect of period was observed in the number of goblet cells containing acid, neutral and total mucins, sialomucins and Vv (P<0.05). In the posterior intestine, effect of period was observed in the thickness of muscle layer and number of goblet cells containing sialomucins and sulphomucins (P<0.05). Considering the aspects studied, the presence of lyophilized bovine colostrum in the diet did not significantly influence the enteric histological characteristics of juvenile dourado during the period of the study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carnivorous%20fish" title="carnivorous fish">carnivorous fish</a>, <a
