However, for thin-surface pavements subject to light or medium traffic volumes, the importance of the non-linear stress-strain behavior of unbound granular materials requires the use of more sophisticated numerical models for the structural design of these pavements. The simplified analysis of the nonlinear behavior of granular materials in pavement design will be developed in this study. To achieve this objective, an equivalent linear model derived from a volumetric shear stress model is used to simulate the nonlinear elastic behavior of two unlinked local granular materials often used in pavements. This model is included here to adequately incorporate material non-linearity due to stress dependence and stiffness of the granular layers in the flexible pavement analysis. The sensitivity of the pavement design criteria to the likely variations in asphalt layer thickness and the mineralogical nature of unbound granular materials commonly used in pavement structures are also evaluated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=granular%20materials" title="granular materials">granular materials</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20equivalent%20model" title=" linear equivalent model"> linear equivalent model</a>, <a href="https://publications.waset.org/abstracts/search?q=non-linear%20behavior" title=" non-linear behavior"> non-linear behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=pavement%20design" title=" pavement design"> pavement design</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20volumetric%20strain%20model" title=" shear volumetric strain model"> shear volumetric strain model</a> </p> <a href="https://publications.waset.org/abstracts/95649/non-linear-behavior-of-granular-materials-in-pavement-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95649.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">177</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">19</span> Firefighting Means in Food Industries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Racim%20Rifaat%20Ferdjani">Racim Rifaat Ferdjani</a>, <a href="https://publications.waset.org/abstracts/search?q=Zineddine%20Chetoui"> Zineddine Chetoui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The goal of our work is to provide a tool that helps control and ensures a global view of the means of firefighting (MLCI) in a food production plant (for example Hamoud Boualem plant).

A computational method based on a Linear Statistical Model (LSM) is implemented to predict second order statistics for the response of a typical industrial building structure. The significance of random damping with correlated parameters and its implications on the sensitivity of structural peak response in the neighborhood of a resonant frequency are discussed in light of considerable ranges of damping uncertainties and correlation coefficients. The results are compared to those generated using Monte Carlo simulation techniques. The numerical results obtained show the importance of damping uncertainty and statistical correlation of damping coefficients when obtaining accurate probabilistic estimates of dynamic response of structures.

In the present work, nonlinear unbound aggregates constitutive model is implemented within an axisymmetric finite element code developed to simulate the nonlinear behaviour of pavement structures including two local aggregates of different mineralogical nature, typically used in Algerian pavements. The performance of the mechanical model is examined about its capability of representing adequately, under various conditions, the granular material non-linearity in pavement analysis.

This paper presents the seismic response of concrete gravity dams considering friction contact and welded contact. Friction contact is provided using contact elements. Two-dimensional (2D) finite element model of Oued Fodda concrete gravity dam, located in Chlef at the west of Algeria, is used for this purpose. Linear and nonlinear analyses considering dam-foundation soil interaction are performed using ANSYS software. The reservoir water is modeled as added mass using the Westergaard approach. The Drucker-Prager model is preferred for dam and foundation rock in nonlinear analyses. The surface-to-surface contact elements based on the Coulomb's friction law are used to describe the friction. These contact elements use a target surface and a contact surface to form a contact pair. According to this study, the seismic analysis of concrete gravity dams including base sliding. When the friction contact is considered in joints, the base sliding displacement occurs along the dam-foundation soil contact interface. Besides, the base sliding may generally decrease the principal stresses in the dam. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concrete%20gravity%20dam" title="concrete gravity dam">concrete gravity dam</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20soil-structure%20interaction" title=" dynamic soil-structure interaction"> dynamic soil-structure interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20contact" title=" friction contact"> friction contact</a>, <a href="https://publications.waset.org/abstracts/search?q=sliding" title=" sliding"> sliding</a> </p> <a href="https://publications.waset.org/abstracts/27934/two-dimensional-seismic-response-of-concrete-gravity-dams-including-base-sliding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27934.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">407</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">15</span> Stability Analysis of Three-Lobe Journal Bearing Lubricated with a Micropolar Fluids</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Boualem%20Chetti">Boualem Chetti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The dynamic characteristics of a three-lobe journal bearing lubricated with micropolar fluids are determined by the linear stability theory.

The validation and numerical performance of this model are assessed by confronting critical pavement responses with Burmister’s solution and FEM simulation results for multi-layered elastic structures. The coupled model is then efficiently utilised to perform 3-D simulations of a typical asphalt pavement structure in order to investigate the impact of two tire configurations (conventional dual and new generation wide-base tires) on critical pavement response parameters. The numerical results obtained show the effectiveness and the accuracy of the coupled (FE-MIE) model. In addition, the simulation results indicate that, compared with conventional dual tire assembly, single wide base tire caused slightly greater fatigue asphalt cracking and subgrade rutting potentials and can thus be utilised in view of its potential to provide numerous mechanical, economic, and environmental benefits. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3-D%20numerical%20investigation" title="3-D numerical investigation">3-D numerical investigation</a>, <a href="https://publications.waset.org/abstracts/search?q=asphalt%20pavements" title=" asphalt pavements"> asphalt pavements</a>, <a href="https://publications.waset.org/abstracts/search?q=dual%20and%20wide%20base%20tires" title=" dual and wide base tires"> dual and wide base tires</a>, <a href="https://publications.waset.org/abstracts/search?q=Infinite%20elements" title=" Infinite elements"> Infinite elements</a> </p> <a href="https://publications.waset.org/abstracts/77709/3d-numerical-investigation-of-asphalt-pavements-behaviour-using-infinite-elements" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77709.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">215</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">12</span> The Influence of Water Content on the Shear Resistance of Silty Sands</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Boualem%20Salah">Mohamed Boualem Salah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work involves an experimental study of the behavior of chlef sand under effect of various parameters influencing on shear strength. Because of their distinct nature, sands, silts and clays exhibit completely different behavior (shear strength, the contracting and dilatancy, the angle of internal friction and cohesion etc.). By cons when these materials are mixed, their behavior will become different from each considered alone. The behavior of these mixtures (silty sands etc.) is currently the state of several studies to better use.

The second objective of this work is to investigate the influence of momentum coefficient of synthetic jet on the flow behaviour. The unsteady Reynolds-averaged Navier-Stokes equations of the turbulent flow are solved using, k-ω SST provided by ANSYS CFX-CFD code. The model presented in this paper is a comprehensive representation of the information found in the literature. Comparison of obtained numerical flow parameters with the experimental ones shows that the adopted computational procedure reflects nearly the real flow nature. Also, numerical results state that use of synthetic jets devices has positive effects on the flow separation, and thus, aerodynamic performance improvement of NACA0015 airfoil. It can also be observed that the use of synthetic jet increases the lift coefficient about 13.3% and reduces the drag coefficient about 52.7%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=active%20control" title="active control">active control</a>, <a href="https://publications.waset.org/abstracts/search?q=synthetic%20jet" title=" synthetic jet"> synthetic jet</a>, <a href="https://publications.waset.org/abstracts/search?q=NACA%20airfoil" title=" NACA airfoil"> NACA airfoil</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD" title=" CFD"> CFD</a> </p> <a href="https://publications.waset.org/abstracts/58346/numerical-investigation-of-improved-aerodynamic-performance-of-a-naca-0015-airfoil-using-synthetic-jet" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58346.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">313</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">9</span> The Historical Framework of International Crime in International Criminal Law</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tahraoui%20Boualem">Tahraoui Boualem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Researching the historical framework of international crime means examining the historical facts that have contributed to uncovering this serious crime affecting international interests, and the law by which the study of the subject of international crime is determined is international criminal law, which is a branch of public international law.

In turn, the macro scale behavior of the soil mass results from particle level interactions which are affected by particle shape. Sphericity, roundness and smoothness characterize different scales associated to particle shape. New experimental data and data from previously published studies are gathered into two databases to explore the effects of particle shape on packing as well as small and large-strain properties of sandy soils. Data analysis shows that increased particle irregularity (angularity and/or eccentricity) leads to: an increase in emax and emin, a decrease in stiffness yet with increased sensitivity to the state of stress, an increase in compressibility under zero-lateral strain loading, and an increase in critical state friction angle 蠁cs and intercept 螕 with a weak effect on slope 位. Therefore, particle shape emerges as a significant soil index property that needs to be properly characterized and documented, particularly in clean sands and gravels.

The effects of the uniaxial anisotropy and the loss tangent on resonant frequencies of microstrip patches consist of two perfectly conducting rectangular patches in stacked and offset configuration, embedded in a bilayer medium containing isotropic or uniaxial anisotropic materials. The Green鈥檚 functions are discussed in detail and numerical results are validated by comparing the computed results with previously published data. The numerical results show, that the uniaxial anisotropy has more effects on resonant frequencies according to the optical axis. However, the loss tangent of dielectric substrates has almost no effect on resonant frequencies, but it strongly affects the imaginary parts of the resonant frequencies of the antenna.

In this paper we are interested to take account of the conflict in the combination step that took the conflict into account and tries to manage such a way that it does not influence the decision step, the conflict what from reliable sources. According to [1], the conflict lead to erroneous decisions in cases where was with strong degrees between sources of information, if the conflict is more than the maximum of the functions of belief mass K > max1...n (mi (A)), then the decision becomes impossible. We will demonstrate in this paper that the multiplication of mass functions by coefficients of reliability is a decreasing function; it leads to the reduction of conflict and a good decision. The definition of reliability coefficients accurately and multiply them by the mass functions of each information source to resolve the conflict and allow deciding whether the degree of conflict. The evaluation of this technique is done by a use case; a comparison of the combination of springs with a maximum conflict without, and with reliability coefficients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dempster-Shafer%20theory" title="Dempster-Shafer theory">Dempster-Shafer theory</a>, <a href="https://publications.waset.org/abstracts/search?q=fusion%20process" title=" fusion process"> fusion process</a>, <a href="https://publications.waset.org/abstracts/search?q=conflict%20managing" title=" conflict managing"> conflict managing</a>, <a href="https://publications.waset.org/abstracts/search?q=reliability%20factors" title=" reliability factors"> reliability factors</a>, <a href="https://publications.waset.org/abstracts/search?q=decision" title=" decision"> decision</a> </p> <a href="https://publications.waset.org/abstracts/23560/on-the-use-of-reliability-factors-to-reduce-conflict-between-information-sources-in-dempster-shafer-theory" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23560.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">426</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">4</span> A Steady State Characteristics of Four-Lobe Journal Bearing Lubricated with a Couple Stress Fluids in Turbulent Flow Regime</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Boualem%20Chetti">Boualem Chetti</a>, <a href="https://publications.waset.org/abstracts/search?q=Samir%20%20Zahaf"> Samir Zahaf</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the steady-state performance analysis of a four-lobe journal bearing lubricated with a couple stress fluids operating in the turbulent regime, following Constantinescu鈥檚 turbulent lubrication theory.

The sharp interface model developed in this research can serve as a valuable tool for assessing and monitoring the vulnerability of aquifers to seawater intrusion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=seawater%20intrusion" title="seawater intrusion">seawater intrusion</a>, <a href="https://publications.waset.org/abstracts/search?q=sharp%20interface" title=" sharp interface"> sharp interface</a>, <a href="https://publications.waset.org/abstracts/search?q=coastal%20aquifer" title=" coastal aquifer"> coastal aquifer</a>, <a href="https://publications.waset.org/abstracts/search?q=algeria" title=" algeria"> algeria</a> </p> <a href="https://publications.waset.org/abstracts/173325/a-sharp-interface-model-for-simulating-seawater-intrusion-in-the-coastal-aquifer-of-wadi-nador-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173325.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">119</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">1</span> Statistical Modeling and by Artificial Neural Networks of Suspended Sediment Mina River Watershed at Wadi El-Abtal Gauging Station (Northern Algeria)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Redhouane%20Ghernaout">Redhouane Ghernaout</a>, <a href="https://publications.waset.org/abstracts/search?q=Amira%20Fredj"> Amira Fredj</a>, <a href="https://publications.waset.org/abstracts/search?q=Boualem%20Remini"> Boualem Remini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Suspended sediment transport is a serious problem worldwide, but it is much more worrying in certain regions of the world, as is the case in the Maghreb and more particularly in Algeria. It continues to take disturbing proportions in Northern Algeria due to the variability of rains in time and in space and constant deterioration of vegetation. Its prediction is essential in order to identify its intensity and define the necessary actions for its reduction. The purpose of this study is to analyze the concentration data of suspended sediment measured at Wadi El-Abtal Hydrometric Station. It also aims to find and highlight regressive power relationships, which can explain the suspended solid flow by the measured liquid flow. The study strives to find models of artificial neural networks linking the flow, month and precipitation parameters with solid flow. The obtained results show that the power function of the solid transport rating curve and the models of artificial neural networks are appropriate methods for analysing and estimating suspended sediment transport in Wadi Mina at Wadi El-Abtal Hydrometric Station. They made it possible to identify in a fairly conclusive manner the model of neural networks with four input parameters: the liquid flow Q, the month and the daily precipitation measured at the representative stations (Frenda 013002 and Ain El-Hadid 013004 ) of the watershed. The model thus obtained makes it possible to estimate the daily solid flows (interpolate and extrapolate) even beyond the period of observation of solid flows (1985/86 to 1999/00), given the availability of the average daily liquid flows and daily precipitation since 1953/1954. <p class="card-text"><strong>Keywords:</strong> <a
