On the other hand, applying this criterion to characteristic equation of a system, whose stability or marginal stability can be determined. Although the command roots (.) of MATLAB software can be easily used to determine the roots of a polynomial, the characteristic equation of closed loop system usually includes parameters, so software cannot handle it; however, Routh-Hurwitz stability criterion results the region of parameter changes where the stability is guaranteed. Moreover, this criterion has been extended to characterize the stability of interval polynomials as well as fractional-order polynomials. Furthermore, it can help us to design stable and minimum-phase controllers. In this paper, theory and application of this criterion will be reviewed. Also, several illustrative examples are given. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hurwitz%20polynomials" title="Hurwitz polynomials">Hurwitz polynomials</a>, <a href="https://publications.waset.org/abstracts/search?q=Routh-Hurwitz%20stability%20criterion" title=" Routh-Hurwitz stability criterion"> Routh-Hurwitz stability criterion</a>, <a href="https://publications.waset.org/abstracts/search?q=continued%20fraction%20expansion" title=" continued fraction expansion"> continued fraction expansion</a>, <a href="https://publications.waset.org/abstracts/search?q=pure%20imaginary%20roots" title=" pure imaginary roots"> pure imaginary roots</a> </p> <a href="https://publications.waset.org/abstracts/72768/a-survey-on-routh-hurwitz-stability-criterion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72768.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">663</span> A Criterion for Evaluating Plastic Loads: Plastic Work-Tangent Criterion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ying%20Zhang">Ying Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In ASME Boiler and Pressure Vessel Code, the plastic load is defined by applying the twice elastic slope (TES) criterion of plastic collapse to a characteristic load-deformation curve for the vessel. Several other plastic criterion such as tangent intersection (TI) criterion, plastic work (PW) criterion have been proposed in the literature, but all exhibit a practical limitation: difficult to define the load parameter for vessels subject to several combined loads. An alternative criterion: plastic work-tangent (PWT) criterion for evaluating plastic load in pressure vessel design by analysis is presented in this paper. According to the plastic work-load curve, when the tangent variation is less than a given value in the plastic phase, the corresponding load is the plastic load. Application of the proposed criterion is illustrated by considering the elastic-plastic response of the lower head of reactor pressure vessel (RPV) and nozzle intersection of (RPV). It is proposed that this is because the PWT criterion more fully represents the constraining effect of material strain hardening on the spread of plastic deformation and more efficiently ton evaluating the plastic load. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=plastic%20load" title="plastic load">plastic load</a>, <a href="https://publications.waset.org/abstracts/search?q=plastic%20work" title=" plastic work"> plastic work</a>, <a href="https://publications.waset.org/abstracts/search?q=strain%20hardening" title=" strain hardening"> strain hardening</a>, <a href="https://publications.waset.org/abstracts/search?q=plastic%20work-tangent%20criterion" title=" plastic work-tangent criterion"> plastic work-tangent criterion</a> </p> <a href="https://publications.waset.org/abstracts/59204/a-criterion-for-evaluating-plastic-loads-plastic-work-tangent-criterion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59204.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">355</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">662</span> Contribution to the Analytical Study of the Stability of a DC-DC Converter (Boost) Used for MPPT Control</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Amarouayache">Mohamed Amarouayache</a>, <a href="https://publications.waset.org/abstracts/search?q=Badia%20Amrouche"> Badia Amrouche</a>, <a href="https://publications.waset.org/abstracts/search?q=Gharbi%20Akila"> Gharbi Akila</a>, <a href="https://publications.waset.org/abstracts/search?q=Boukadoume%20Mohamed"> Boukadoume Mohamed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work is devoted to the modeling of DC-DC converter (boost) used for MPPT applications to set conditions of stability.

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">659</span> Extended Strain Energy Density Criterion for Fracture Investigation of Orthotropic Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Fakoor">Mahdi Fakoor</a>, <a href="https://publications.waset.org/abstracts/search?q=Hannaneh%20Manafi%20Farid"> Hannaneh Manafi Farid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to predict the fracture behavior of cracked orthotropic materials under mixed-mode loading, well-known minimum strain energy density (SED) criterion is extended. The crack is subjected along the fibers at plane strain conditions. Despite the complicities to solve the nonlinear equations which are requirements of SED criterion, SED criterion for anisotropic materials is derived. In the present research, fracture limit curve of SED criterion is depicted by a numerical solution, hence the direction of crack growth is figured out by derived criterion, MSED. The validated MSED demonstrates the improvement in prediction of fracture behavior of the materials. Also, damaged factor that plays a crucial role in the fracture behavior of quasi-brittle materials is derived from this criterion and proved its dependency on mechanical properties and direction of crack growth. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mixed-mode%20fracture" title="mixed-mode fracture">mixed-mode fracture</a>, <a href="https://publications.waset.org/abstracts/search?q=minimum%20strain%20energy%20density%20criterion" title=" minimum strain energy density criterion"> minimum strain energy density criterion</a>, <a href="https://publications.waset.org/abstracts/search?q=orthotropic%20materials" title=" orthotropic materials"> orthotropic materials</a>, <a href="https://publications.waset.org/abstracts/search?q=fracture%20limit%20curve" title=" fracture limit curve"> fracture limit curve</a>, <a href="https://publications.waset.org/abstracts/search?q=mode%20II%20critical%20stress%20intensity%20factor" title=" mode II critical stress intensity factor"> mode II critical stress intensity factor</a> </p> <a href="https://publications.waset.org/abstracts/91812/extended-strain-energy-density-criterion-for-fracture-investigation-of-orthotropic-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91812.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">167</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">658</span> Controller Design for Active Suspension System of 1/4 Car with Unknown Mass and Time-Delay </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Al-Zughaibi">Ali Al-Zughaibi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this paper is to present a modeling and control of the quarter car active suspension system with unknown mass, unknown time-delay and road disturbance.

Created fracture process zone (FPZ) in crack tip vicinity has important effect on failure of cracked composite materials. In this paper, a failure criterion for fracture investigation of cracked wood specimens under mixed mode I/II loading is presented. This criterion is based on maximum strain energy release rate and material nonlinearity in the vicinity of crack tip due to presence of microcracks. Verification of results with available experimental data proves the coincidence of the proposed criterion with the nature of fracture of wood. To simplify the estimation of nonlinear properties of FPZ, a damage factor is also introduced for engineering and application purposes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fracture%20criterion" title="fracture criterion">fracture criterion</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20mode%20loading" title=" mixed mode loading"> mixed mode loading</a>, <a href="https://publications.waset.org/abstracts/search?q=damage%20zone" title=" damage zone"> damage zone</a>, <a href="https://publications.waset.org/abstracts/search?q=micro%20cracks" title=" micro cracks"> micro cracks</a> </p> <a href="https://publications.waset.org/abstracts/72822/failure-criterion-for-mixed-mode-fracture-of-cracked-wood-specimens" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72822.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">298</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">655</span> Inclusion and Changes of a Research Criterion in the Institute for Quality and Accreditation of Computing, Engineering and Technology Accreditation Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20Daniel%20Sanchez%20Ruiz">J.

However, SIC is defined using an unbounded estimator, namely, the least-squares (LS), which is highly sensitive to outlying observations, especially bad leverage points. A method for robust variable selection based on SIC for linear regression models is thus needed. This study investigates the robustness properties of SIC by deriving its influence function and proposes a robust SIC based on the MM-estimation scale. The aim of this study is to produce a criterion that can effectively select accurate models in the presence of vertical outliers and high leverage points. The advantages of the proposed robust SIC is demonstrated through a simulation study and an analysis of a real dataset. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=influence%20function" title="influence function">influence function</a>, <a href="https://publications.waset.org/abstracts/search?q=robust%20variable%20selection" title=" robust variable selection"> robust variable selection</a>, <a href="https://publications.waset.org/abstracts/search?q=robust%20regression" title=" robust regression"> robust regression</a>, <a href="https://publications.waset.org/abstracts/search?q=Schwarz%20information%20criterion" title=" Schwarz information criterion"> Schwarz information criterion</a> </p> <a href="https://publications.waset.org/abstracts/131338/robust-variable-selection-based-on-schwarz-information-criterion-for-linear-regression-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131338.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">139</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">653</span> New Stress Instability Workability Criteria for Internal Ductile Failure in Steel Cold Heading</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amar%20Sabih">Amar Sabih</a>, <a href="https://publications.waset.org/abstracts/search?q=James%20Nemes"> James Nemes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The occurrence of internal ductile failure within the Adiabatic Shear Band (ASB) in cold-headed products presents a significant barrier in the fast-expanding cold-heading (CH) industry.

In such a situation, the strength and load bearing capacity of the drill are evaluated based on the principles of fracture mechanics and crack growth criteria. In this paper, using the three-dimensional stress equations around the Turkish frontier, the relations of the tense-tense criterion (MTS) are extracted for the loading of the combined II and III modulus. It is shown that in crisp deflection under loading of combination II and III, the level of fracture is characterized by two different angles: the longitudinal angle of deflection θ and the angle of the deflection of the alpha. Based on the relationships obtained from the MTS criterion, the failure criteria, the longitudinal angle of the theta failure and the lateral angle of the failure of the alpha are presented. Also, the role of Poisson's coefficient on these parameters is investigated in these graphs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=most%20tangential%20tension%20criterion" title="most tangential tension criterion">most tangential tension criterion</a>, <a href="https://publications.waset.org/abstracts/search?q=longitudinal%20angle%20of%20failure" title=" longitudinal angle of failure"> longitudinal angle of failure</a>, <a href="https://publications.waset.org/abstracts/search?q=side%20angle%20of%20fracture" title=" side angle of fracture"> side angle of fracture</a>, <a href="https://publications.waset.org/abstracts/search?q=drills%20crack" title=" drills crack"> drills crack</a> </p> <a href="https://publications.waset.org/abstracts/101747/extracting-the-failure-criterion-to-evaluate-the-strength-of-cracked-drills-under-torque-caused-by-drilling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101747.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">651</span> A Novel Stress Instability Workability Criteria for Internal Ductile Failure in Steel Cold Heading Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amar%20Sabih">Amar Sabih</a>, <a href="https://publications.waset.org/abstracts/search?q=James%20Nemes"> James Nemes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The occurrence of internal ductile failure within the Adiabatic Shear Band (ASB) in cold-headed products presents a significant barrier in the fast-expanding cold-heading (CH) industry.

This paper presents an algorithm which improves the simulation speed of estimating EMC of RCE in a complex EME, based on a stage by stage frequency-energy criterion of filtering. This algorithm considers different interference types including: Blocking and intermodulation. It consist of the following steps: simplified energy criterion where filtration is based on comparing the free space interference level to the industrial noise, frequency criterion which checks whether the interfering emissions characteristic overlap with the receiver’s channels characteristic and lastly the detailed energy criterion where the real channel interference level is compared to the noise level. In each of these stages, some interference cases are filtered out by the relevant criteria. This reduces the total number of dual and different combinations of RCE involved in the tedious detailed energy analysis and thus provides an improved simulation speed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electromagnetic%20compatibility" title="electromagnetic compatibility">electromagnetic compatibility</a>, <a href="https://publications.waset.org/abstracts/search?q=electromagnetic%20environment" title=" electromagnetic environment"> electromagnetic environment</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation%20of%20communication%20network" title=" simulation of communication network"> simulation of communication network</a> </p> <a href="https://publications.waset.org/abstracts/1966/a-fast-algorithm-for-electromagnetic-compatibility-estimation-for-radio-communication-network-equipment-in-a-complex-electromagnetic-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1966.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">218</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">649</span> Non-Parametric Regression over Its Parametric Couterparts with Large Sample Size</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jude%20Opara">Jude Opara</a>, <a href="https://publications.waset.org/abstracts/search?q=Esemokumo%20Perewarebo%20Akpos"> Esemokumo Perewarebo Akpos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper is on non-parametric linear regression over its parametric counterparts with large sample size. Data set on anthropometric measurement of primary school pupils was taken for the analysis. The study used 50 randomly selected pupils for the study. The set of data was subjected to normality test, and it was discovered that the residuals are not normally distributed (i.e. they do not follow a Gaussian distribution) for the commonly used least squares regression method for fitting an equation into a set of (x,y)-data points using the Anderson-Darling technique. The algorithms for the nonparametric Theil’s regression are stated in this paper as well as its parametric OLS counterpart. The use of a programming language software known as “R Development” was used in this paper. From the analysis, the result showed that there exists a significant relationship between the response and the explanatory variable for both the parametric and non-parametric regression. To know the efficiency of one method over the other, the Akaike Information Criterion (AIC), Bayesian Information Criterion (BIC) are used, and it is discovered that the nonparametric regression performs better than its parametric regression counterparts due to their lower values in both the AIC and BIC. The study however recommends that future researchers should study a similar work by examining the presence of outliers in the data set, and probably expunge it if detected and re-analyze to compare results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Theil%E2%80%99s%20regression" title="Theil’s regression">Theil’s regression</a>, <a href="https://publications.waset.org/abstracts/search?q=Bayesian%20information%20criterion" title=" Bayesian information criterion"> Bayesian information criterion</a>, <a href="https://publications.waset.org/abstracts/search?q=Akaike%20information%20criterion" title=" Akaike information criterion"> Akaike information criterion</a>, <a href="https://publications.waset.org/abstracts/search?q=OLS" title=" OLS"> OLS</a> </p> <a href="https://publications.waset.org/abstracts/58536/non-parametric-regression-over-its-parametric-couterparts-with-large-sample-size" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58536.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">305</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">648</span> Research on Pilot Sequence Design Method of Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing System Based on High Power Joint Criterion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Linyu%20Wang">Linyu Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiahui%20Ma"> Jiahui Ma</a>, <a href="https://publications.waset.org/abstracts/search?q=Jianhong%20Xiang"> Jianhong Xiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanyu%20Jiang"> Hanyu Jiang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For the pilot design of the sparse channel estimation model in Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) systems, the observation matrix constructed according to the matrix cross-correlation criterion, total correlation criterion and other optimization criteria are not optimal, resulting in inaccurate channel estimation and high bit error rate at the receiver. This paper proposes a pilot design method combining high-power sum and high-power variance criteria, which can more accurately estimate the channel. First, the pilot insertion position is designed according to the high-power variance criterion under the condition of equal power. Then, according to the high power sum criterion, the pilot power allocation is converted into a cone programming problem, and the power allocation is carried out. Finally, the optimal pilot is determined by calculating the weighted sum of the high power sum and the high power variance. Compared with the traditional pilot frequency, under the same conditions, the constructed MIMO-OFDM system uses the optimal pilot frequency for channel estimation, and the communication bit error rate performance obtains a gain of 6~7dB. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MIMO-OFDM" title="MIMO-OFDM">MIMO-OFDM</a>, <a href="https://publications.waset.org/abstracts/search?q=pilot%20optimization" title=" pilot optimization"> pilot optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=compressed%20sensing" title=" compressed sensing"> compressed sensing</a>, <a href="https://publications.waset.org/abstracts/search?q=channel%20estimation" title=" channel estimation"> channel estimation</a> </p> <a href="https://publications.waset.org/abstracts/155508/research-on-pilot-sequence-design-method-of-multiple-input-multiple-output-orthogonal-frequency-division-multiplexing-system-based-on-high-power-joint-criterion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155508.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">149</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">647</span> Application of Fuzzy Multiple Criteria Decision Making for Flooded Risk Region Selection in Thailand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Waraporn%20Wimuktalop">Waraporn Wimuktalop</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research will select regions which are vulnerable to flooding in different level.

A two-dimensional micromechanical model is implemented in finite element software (ZEBULON) to simulate the martensitic transformation in Fe-Ni-C steel grain under mechanical tensile stress of 250 MPa. The effects of non-uniform grain boundary and the criterion of mechanical shear load on the transformation and on the TRIP value during martensitic transformation are studied. The suggested mechanical criterion is favourable to the influence of the shear phenomenon on the progression of the martensitic transformation (Magee’s mechanism).

AEH's perpetual reactivation compels us to look closely at its triggers and to better understand the mechanisms of its evolution in mass and in depth. This study builds a numerical model to simulate the influencing factors such as precipitation, non-saturation, and pore pressure fluctuations, using Plaxis software. For a finer analysis of instabilities, we use Hill's criterion, based on the sign of the second order work, which is the most appropriate material stability criterion for non-associated elastoplastic materials. The results of this type of calculation allow us, in theory, to predict the shape and position of the slip surface(s) which are liable to ground movements of the slope, before reaching the rupture given by the plastic limit of Mohr Coulomb. To validate the numerical model, an analysis of inclinometer measures is performed to confirm the direction of movement and kinematic of the sliding mechanism of AEH’s slope. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=landslide" title="landslide">landslide</a>, <a href="https://publications.waset.org/abstracts/search?q=second%20order%20work" title=" second order work"> second order work</a>, <a href="https://publications.waset.org/abstracts/search?q=precipitation" title=" precipitation"> precipitation</a>, <a href="https://publications.waset.org/abstracts/search?q=inclinometers" title=" inclinometers"> inclinometers</a> </p> <a href="https://publications.waset.org/abstracts/84706/analysis-and-prediction-of-the-behavior-of-the-landslide-at-ain-el-hammam-algeria-based-on-the-second-order-work-criterion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84706.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">178</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">643</span> Stability Analysis of Rabies Model with Vaccination Effect and Culling in Dogs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eti%20Dwi%20Wiraningsih">Eti Dwi Wiraningsih</a>, <a href="https://publications.waset.org/abstracts/search?q=Folashade%20Agusto"> Folashade Agusto</a>, <a href="https://publications.waset.org/abstracts/search?q=Lina%20Aryati"> Lina Aryati</a>, <a href="https://publications.waset.org/abstracts/search?q=Syamsuddin%20Toaha"> Syamsuddin Toaha</a>, <a href="https://publications.waset.org/abstracts/search?q=Suzanne%20Lenhart"> Suzanne Lenhart</a>, <a href="https://publications.waset.org/abstracts/search?q=Widodo"> Widodo</a>, <a href="https://publications.waset.org/abstracts/search?q=Willy%20Govaerts"> Willy Govaerts</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper considers a deterministic model for the transmission dynamics of rabies virus in the wild dogs-domestic dogs-human zoonotic cycle.

Many preeminent and well-known scientists from an earlier era of groundbreaking discoveries attempted to solve the issue of material failure. However, a thorough understanding of material failure has been frustratingly elusive. Objective: The heart of this study is the presentation of a methodology that identifies a newly derived one-parameter criterion as the only general failure theory for noncompressible, homogeneous, and isotropic materials subjected to multiaxial states of stress and various boundary conditions, providing the solution to this longstanding problem. This theory is the counterpart and companion piece to the theory of elasticity and is in a formalism that is suitable for broad application. Methods: Utilizing advanced finite-element analysis, the maximum internal breaking stress corresponding to the maximum applied external force is identified as a unified and universal material failure criterion for determining the structural capacity of any system, regardless of its geometry or architecture. Results: A comparison between the proposed criterion and methodology against design codes reveals that current provisions may underestimate the structural capacity by 2.17 times or overestimate the capacity by 2.096 times. It also shows that existing standards may underestimate the structural capacity by 1.4 times or overestimate the capacity by 2.49 times. Conclusion: The proposed failure criterion and methodology will pave the way for a new era in designing unconventional structural systems composed of unconventional materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=failure%20criteria" title="failure criteria">failure criteria</a>, <a href="https://publications.waset.org/abstracts/search?q=strength%20theory" title=" strength theory"> strength theory</a>, <a href="https://publications.waset.org/abstracts/search?q=failure%20mechanics" title=" failure mechanics"> failure mechanics</a>, <a href="https://publications.waset.org/abstracts/search?q=materials%20mechanics" title=" materials mechanics"> materials mechanics</a>, <a href="https://publications.waset.org/abstracts/search?q=rock%20mechanics" title=" rock mechanics"> rock mechanics</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete%20strength" title=" concrete strength"> concrete strength</a>, <a href="https://publications.waset.org/abstracts/search?q=finite-element%20analysis" title=" finite-element analysis"> finite-element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20engineering" title=" mechanical engineering"> mechanical engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=aeronautical%20engineering" title=" aeronautical engineering"> aeronautical engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=civil%20engineering" title=" civil engineering"> civil engineering</a> </p> <a href="https://publications.waset.org/abstracts/167552/breaking-stress-criterion-that-changes-everything-we-know-about-materials-failure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167552.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">78</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">641</span> Proposing a Failure Criterion for Cohesionless Media Considering Cyclic Fabric Anisotropy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Noorzad">Ali Noorzad</a>, <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Badakhshan"> Ehsan Badakhshan</a>, <a href="https://publications.waset.org/abstracts/search?q=Shima%20Zameni"> Shima Zameni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present paper is focused on a generalized failure criterion for geomaterials with cross-anisotropy. The cyclic behavior of granular material primarily depends on the nature and arrangement of constituent particles, particle size, and shape that affect fabric anisotropy. To account for the influence of loading directions on strength variations, an anisotropic variable in terms of the invariants of the stress tensor and fabric into the failure criterion is proposed. In an extension to original CANAsand constitutive model two concepts namely critical state and compact state play paramount roles as all of the moduli and coefficients are related to these states. The applicability of the present model is evaluated through comparisons between the predicted and the measured results. All simulations have demonstrated that the proposed constitutive model is capable of modeling the cyclic behavior of sand with inherent anisotropy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fabric" title="fabric">fabric</a>, <a href="https://publications.waset.org/abstracts/search?q=cohesionless%20media" title=" cohesionless media"> cohesionless media</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclic%20loading" title=" cyclic loading"> cyclic loading</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20state" title=" critical state"> critical state</a>, <a href="https://publications.waset.org/abstracts/search?q=compact%20state" title=" compact state"> compact state</a>, <a href="https://publications.waset.org/abstracts/search?q=CANAsand%20constitutive%20model" title=" CANAsand constitutive model"> CANAsand constitutive model</a> </p> <a href="https://publications.waset.org/abstracts/80943/proposing-a-failure-criterion-for-cohesionless-media-considering-cyclic-fabric-anisotropy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80943.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">219</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">640</span> Power Circuit Schemes in AC Drive is Made by Condition of the Minimum Electric Losses</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20A.%20Grigoryev">M.

The specific weighting factors are calculation, the linear regression dependence of specific losses in semiconductor frequency converters are presented depending on the values of the rated current. It is revealed that with increase of the carrier frequency PWM improves the output current waveform, but increases the loss, so you will need depending on the task in a certain way to choose from the carrier frequency. For task of optimization by criterion of the minimum electrical losses regression dependence of the electrical losses in the frequency converter circuit at a frequency of a PWM signal of 0 Hz. The surface optimization criterion is presented depending on the rated output torque of the motor and number of phases. In electric drives with field regulated reluctance machine with at low output power optimization criterion appears to be the worst for multiphase circuits. With increasing output power this trend hold true, but becomes insignificantly different optimal solutions for three-phase and multiphase circuits. This is explained to the linearity of the dependence of the electrical losses from the current. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=field%20regulated%20reluctance%20machine" title="field regulated reluctance machine">field regulated reluctance machine</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20electrical%20losses" title=" the electrical losses"> the electrical losses</a>, <a href="https://publications.waset.org/abstracts/search?q=multiphase%20power%20circuit" title=" multiphase power circuit"> multiphase power circuit</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20surface%20optimization%20criterion" title=" the surface optimization criterion"> the surface optimization criterion</a> </p> <a href="https://publications.waset.org/abstracts/46140/power-circuit-schemes-in-ac-drive-is-made-by-condition-of-the-minimum-electric-losses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46140.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">294</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">639</span> A New Criterion Using Pose and Shape of Objects for Collision Risk Estimation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=DoHyeung%20Kim">DoHyeung Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=DaeHee%20Seo"> DaeHee Seo</a>, <a href="https://publications.waset.org/abstracts/search?q=ByungDoo%20Kim"> ByungDoo Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=ByungGil%20Lee"> ByungGil Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As many recent researches being implemented in aviation and maritime aspects, strong doubts have been raised concerning the reliability of the estimation of collision risk.

ABET is a non-governmental agency that accredits engineering and technology, applied and natural sciences, and computing sciences programs. ABET was founded on 10th May 1932 and was founded by Institute of Electrical and Electronics Engineering. International industries accept ABET accredited institutes having the highest standards in their academic programs. In this accreditation, there are eight criteria in general; criterion 1 describes the student outcome evaluations, criteria 2 measures the program's educational objectives, criteria 3 is the student outcome calculated from the marks obtained by students, criteria 4 establishes continuous improvement, criteria 5 focus on curriculum of the institute, criteria 6 is about faculties of this institute, criteria 7 measures the facilities provided by the institute and finally, criteria 8 focus on institutional support towards staff of the institute. In this paper, we focused on the calculative part of each criterion with equations and suitable examples, the files and documentation required for each criterion, and the total workflow of the process. The references and the values used to illustrate the calculations are all taken from the samples provided at ABET's official website. In the final section, we also discuss the criterion-wise score weightage followed by evaluation with timeframe and deadlines. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Engineering%20Accreditation%20Committee" title="Engineering Accreditation Committee">Engineering Accreditation Committee</a>, <a href="https://publications.waset.org/abstracts/search?q=Computing%20Accreditation%20Committee" title=" Computing Accreditation Committee"> Computing Accreditation Committee</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20indicator" title=" performance indicator"> performance indicator</a>, <a href="https://publications.waset.org/abstracts/search?q=Program%20Educational%20Objective" title=" Program Educational Objective"> Program Educational Objective</a>, <a href="https://publications.waset.org/abstracts/search?q=ABET%20Criterion%201%20to%207" title=" ABET Criterion 1 to 7"> ABET Criterion 1 to 7</a>, <a href="https://publications.waset.org/abstracts/search?q=IEEE" title=" IEEE"> IEEE</a>, <a href="https://publications.waset.org/abstracts/search?q=National%20Board%20of%20Accreditation" title=" National Board of Accreditation"> National Board of Accreditation</a>, <a href="https://publications.waset.org/abstracts/search?q=MOOCS" title=" MOOCS"> MOOCS</a>, <a href="https://publications.waset.org/abstracts/search?q=Board%20of%20Studies" title=" Board of Studies"> Board of Studies</a>, <a href="https://publications.waset.org/abstracts/search?q=stakeholders" title=" stakeholders"> stakeholders</a>, <a href="https://publications.waset.org/abstracts/search?q=course%20objective" title=" course objective"> course objective</a>, <a href="https://publications.waset.org/abstracts/search?q=program%20outcome" title=" program outcome"> program outcome</a>, <a href="https://publications.waset.org/abstracts/search?q=articulation" title=" articulation"> articulation</a>, <a href="https://publications.waset.org/abstracts/search?q=attainment" title=" attainment"> attainment</a>, <a href="https://publications.waset.org/abstracts/search?q=CO-PO%20mapping" title=" CO-PO mapping"> CO-PO mapping</a>, <a href="https://publications.waset.org/abstracts/search?q=CO-PO-SO%20mapping" title=" CO-PO-SO mapping"> CO-PO-SO mapping</a>, <a href="https://publications.waset.org/abstracts/search?q=PDCA%20cycle" title=" PDCA cycle"> PDCA cycle</a>, <a href="https://publications.waset.org/abstracts/search?q=degree%20certificates" title=" degree certificates"> degree certificates</a>, <a href="https://publications.waset.org/abstracts/search?q=course%20files" title=" course files"> course files</a>, <a href="https://publications.waset.org/abstracts/search?q=course%20catalogue" title=" course catalogue"> course catalogue</a> </p> <a href="https://publications.waset.org/abstracts/169512/abet-accreditation-process-for-engineering-and-technology-programs-detailed-process-flow-from-criteria-1-to-criteria-8" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169512.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">59</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">637</span> Synthesis of the Robust Regulators on the Basis of the Criterion of the Maximum Stability Degree</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20A.%20Gayvoronsky">S.

The reliability of such tests cannot be based on internal reliability. Threshold loss agreement is one way to calculate the reliability of CRTs. However, the selection of master and non-master in such agreement is determined by the threshold point. The problem is if the threshold point witnesses a minute change, the selection of master and non-master may have a drastic change, leading to the change in reliability results. Therefore, in this study, the Fuzzy logic approach is employed as a remedial procedure for data analysis to obviate the threshold point problem. Forty-one Iranian students were selected; the participants were all between 20 and 30 years old. A quantitative approach was used to address the research questions. In doing so, a quasi-experimental design was utilized since the selection of the participants was not randomized. Based on the Fuzzy logic approach, the threshold point would be more stable during the analysis, resulting in rather constant reliability results and more precise assessment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=criterion-referenced%20tests" title="criterion-referenced tests">criterion-referenced tests</a>, <a href="https://publications.waset.org/abstracts/search?q=threshold%20loss%20agreement" title=" threshold loss agreement"> threshold loss agreement</a>, <a href="https://publications.waset.org/abstracts/search?q=threshold%20point" title=" threshold point"> threshold point</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20logic%20approach" title=" fuzzy logic approach"> fuzzy logic approach</a> </p> <a href="https://publications.waset.org/abstracts/135929/criterion-referenced-test-reliability-through-threshold-loss-agreement-fuzzy-logic-analysis-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135929.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">369</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">635</span> Pseudo Modal Operating Deflection Shape Based Estimation Technique of Mode Shape Using Time History Modal Assurance Criterion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Doyoung%20Kim">Doyoung Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyo%20Seon%20Park"> Hyo Seon Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Studies of System Identification(SI) based on Structural Health Monitoring(SHM) have actively conducted for structural safety. Recently SI techniques have been rapidly developed with output-only SI paradigm for estimating modal parameters. The features of these output-only SI methods consist of Frequency Domain Decomposition(FDD) and Stochastic Subspace Identification(SSI) are using the algorithms based on orthogonal decomposition such as singular value decomposition(SVD). But the SVD leads to high level of computational complexity to estimate modal parameters. This paper proposes the technique to estimate mode shape with lower computational cost. This technique shows pseudo modal Operating Deflections Shape(ODS) through bandpass filter and suggests time history Modal Assurance Criterion(MAC). Finally, mode shape could be estimated from pseudo modal ODS and time history MAC.
