Queries and documents are represented by extended trees. An extended tree is built starting from the original tree, with additional weighted virtual links between each node and its indirect descendants allowing to directly reach each descendant. Therefore only one level separates between each node and its indirect descendants. This allows to compare the user query and the document with flexibility and with respect to the structural constraints of the query. The content of each node is very important to decide weither a document element is relevant or not, thus the content should be taken into account in the retrieval process. We separate between the structure-based and the content-based retrieval processes. The content-based score of each node is commonly based on the well-known Tf 脳 Idf criteria. In this paper, we compare between this criteria and another one we call Tf 脳 Ief. The comparison is based on some experiments into a dataset provided by INEX1 to show the effectiveness of our approach on one hand and those of both weighting functions on the other. <p

This class of materials, called Engineered Cement Composites (ECC) has the potential to be used in future tunneling applications where a level of pseudo-ductility is required to avoid brittle failures. However uncertainties remain regarding mechanical performance. Previous work has focused on comparatively thin specimens; however for future civil engineering applications, it is imperative that the behavior in tension of thicker specimens is understood. In the present work, specimens containing cement powder and admixtures have been manufactured following two different processes and tested in tension. Multiple matrix cracking has been observed during tensile testing, leading to a 鈥渟train-hardening" behavior, confirming the possible suitability of ECC material when used as thick sections (greater than 50mm) in tunneling applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Cement%20composite" title="Cement composite">Cement

A slight variation in global ductility is noticed as (Lx/Ly) varies; however, column sections can control satisfactorily the plastic behavior of buildings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Ductility" title="Ductility">Ductility</a>, <a href="https://publications.waset.org/search?q=nonlinear%20behavior" title=" nonlinear behavior"> nonlinear behavior</a>, <a href="https://publications.waset.org/search?q=pushover%20analysis" title=" pushover analysis"> pushover analysis</a>, <a href="https://publications.waset.org/search?q=geometric%20slenderness" title=" geometric slenderness"> geometric slenderness</a>, <a href="https://publications.waset.org/search?q=structural%20behavior." title=" structural behavior."> structural behavior.</a> </p> <a href="https://publications.waset.org/10003563/influence-of-slenderness-ratio-on-the-ductility-of-reinforced-concrete-portal-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10003563/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10003563/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10003563/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10003563/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10003563/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10003563/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10003563/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10003563/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10003563/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10003563/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10003563.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">1695</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> Introduction of the Harmfulness of the Seismic Signal in the Assessment of the Performance of Reinforced Concrete Frame Structures </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Kahil%20Amar">Kahil Amar</a>, <a href="https://publications.waset.org/search?q=Boukais%20Said"> Boukais Said</a>, <a href="https://publications.waset.org/search?q=Kezmane%20Ali"> Kezmane Ali</a>, <a href="https://publications.waset.org/search?q=Hamizi%20Mohand"> Hamizi Mohand</a>, <a href="https://publications.waset.org/search?q=Hannachi%20Naceur%20Eddine"> Hannachi Naceur Eddine </a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>The principle of the seismic performance evaluation methods is to provide a measure of capability for a building or set of buildings to be damaged by an earthquake. The common objective of many of these methods is to supply classification criteria. The purpose of this study is to present a method for assessing the seismic performance of structures, based on Pushover method; we are particularly interested in reinforced concrete frame structures, which represent a significant percentage of damaged structures after a seismic event. The work is based on the characterization of seismic movement of the various earthquake zones in terms of PGA and PGD that is obtained by means of SIMQK_GR and PRISM software and the correlation between the points of performance and the scalar characterizing the earthquakes will developed.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Seismic%20performance" title="Seismic performance">Seismic performance</a>, <a href="https://publications.waset.org/search?q=Pushover%20method" title=" Pushover method"> Pushover method</a>, <a href="https://publications.waset.org/search?q=characterization%20of%20seismic%20motion" title=" characterization of seismic motion"> characterization of seismic motion</a>, <a href="https://publications.waset.org/search?q=harmfulness%20of%20the%20seismic%20signal" title=" harmfulness of the seismic signal"> harmfulness of the seismic signal</a> </p> <a href="https://publications.waset.org/10001313/introduction-of-the-harmfulness-of-the-seismic-signal-in-the-assessment-of-the-performance-of-reinforced-concrete-frame-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10001313/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10001313/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10001313/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10001313/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10001313/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10001313/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10001313/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10001313/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10001313/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10001313/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10001313.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">2051</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Semi Empirical Equations for Peak Shear Strength of Rectangular Reinforced Concrete Walls</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Ali%20Kezmane">Ali Kezmane</a>, <a href="https://publications.waset.org/search?q=Said%20Boukais"> Said Boukais</a>, <a href="https://publications.waset.org/search?q=Mohand%20Hamizi"> Mohand Hamizi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents an analytical study on the behavior of reinforced concrete walls with rectangular cross section. Several experiments on such walls have been selected to be studied. Database from various experiments were collected and nominal shear wall strengths have been calculated using formulas, such as those of the ACI (American), NZS (New Zealand), Mexican (NTCC), and Wood and Barda equations. Subsequently, nominal shear wall strengths from the formulas were compared with the ultimate shear wall strengths from the database. These formulas vary substantially in functional form and do not account for all variables that affect the response of walls. There is substantial scatter in the predicted values of ultimate shear strength. Two new semi empirical equations are developed using data from tests of 57 walls for transitions walls and 27 for slender walls with the objective of improving the prediction of peak strength of walls with the most possible accurate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Shear%20strength" title="Shear strength">Shear strength</a>, <a href="https://publications.waset.org/search?q=reinforced%20concrete%20walls" title=" reinforced concrete walls"> reinforced concrete walls</a>, <a href="https://publications.waset.org/search?q=rectangular%20walls" title=" rectangular walls"> rectangular walls</a>, <a href="https://publications.waset.org/search?q=shear%20walls" title=" shear walls"> shear walls</a>, <a href="https://publications.waset.org/search?q=models." title=" models."> models.</a> </p> <a href="https://publications.waset.org/10003683/semi-empirical-equations-for-peak-shear-strength-of-rectangular-reinforced-concrete-walls" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10003683/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10003683/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10003683/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10003683/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10003683/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10003683/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10003683/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10003683/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10003683/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10003683/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10003683.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">1452</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Multiple Sensors and JPDA-IMM-UKF Algorithm for Tracking Multiple Maneuvering Targets</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Wissem%20Saidani">Wissem Saidani</a>, <a href="https://publications.waset.org/search?q=Yacine%20Morsly"> Yacine Morsly</a>, <a href="https://publications.waset.org/search?q=Mohand%20Sa%C3%AFd%20Djouadi"> Mohand Sa茂d Djouadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we consider the problem of tracking multiple maneuvering targets using switching multiple target motion models. With this paper, we aim to contribute in solving the problem of model-based body motion estimation by using data coming from visual sensors. The Interacting Multiple Model (IMM) algorithm is specially designed to track accurately targets whose state and/or measurement (assumed to be linear) models changes during motion transition. However, when these models are nonlinear, the IMM algorithm must be modified in order to guarantee an accurate track. In this paper we propose to avoid the Extended Kalman filter because of its limitations and substitute it with the Unscented Kalman filter which seems to be more efficient especially according to the simulation results obtained with the nonlinear IMM algorithm (IMMUKF). To resolve the problem of data association, the JPDA approach is combined with the IMM-UKF algorithm, the derived algorithm is noted JPDA-IMM-UKF. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Estimation" title="Estimation">Estimation</a>, <a href="https://publications.waset.org/search?q=Kalman%20filtering" title=" Kalman filtering"> Kalman filtering</a>, <a href="https://publications.waset.org/search?q=Multi-Target%20Tracking" title=" Multi-Target Tracking"> Multi-Target Tracking</a>, <a href="https://publications.waset.org/search?q=Visual%20servoing" title="Visual servoing">Visual servoing</a>, <a href="https://publications.waset.org/search?q=data%20association." title=" data association."> data association.</a> </p> <a href="https://publications.waset.org/6178/multiple-sensors-and-jpda-imm-ukf-algorithm-for-tracking-multiple-maneuvering-targets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/6178/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/6178/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/6178/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/6178/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/6178/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/6178/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/6178/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/6178/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/6178/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/6178/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/6178.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">2564</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Application of the Piloting Law Based on Adaptive Differentiators via Second Order Sliding Mode for a Fixed Wing Aircraft </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Zaouche%20Mohammed">Zaouche Mohammed</a>, <a href="https://publications.waset.org/search?q=Amini%20Mohammed"> Amini Mohammed</a>, <a href="https://publications.waset.org/search?q=Foughali%20Khaled"> Foughali Khaled</a>, <a href="https://publications.waset.org/search?q=Hamissi%20Aicha"> Hamissi Aicha</a>, <a href="https://publications.waset.org/search?q=Aktouf%20Mohand%20Arezki"> Aktouf Mohand Arezki</a>, <a href="https://publications.waset.org/search?q=Boureghda%20Ilyes"> Boureghda Ilyes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>In this paper, we present a piloting law based on the adaptive differentiators via high order sliding mode controller, by using an aircraft in virtual simulated environment. To deal with the design of an autopilot controller, we propose a framework based on Software in the Loop (SIL) methodology and we use Microsoft<sup>TM</sup> Flight Simulator (FS-2004) as the environment for plane simulation. The aircraft dynamic model is nonlinear, Multi-Input Multi-Output (MIMO) and tightly coupled. The nonlinearity resides in the dynamic equations and also in the aerodynamic coefficients' variability. In our case, two (02) aircrafts are used in the flight tests, the Zlin-142 and MQ-1 Predator. For both aircrafts and in a very low altitude flight, we send the piloting control inputs to the aircraft which has stalled due to a command disconnection. Then, we present the aircraft’s dynamic behavior analysis while reestablishing the command transmission. Finally, a comparative study between the two aircraft’s dynamic behaviors is presented.</p> <p class="card-text"><strong>Keywords:</strong> <a
