Extensive field measurements were conducted in different locations of Al-Madinah Holy Mosque to characterize its acoustic characteristics. The acoustical characteristics are usually evaluated by the use of objective parameters in unoccupied rooms due to practical considerations. However, under normal conditions, the room occupancy can vary such characteristics due to the effect of the additional sound absorption present in the room or by the change in signal-to-noise ratio. Based on the acoustic measurements carried out in Al-Madinah Holy Mosque with and without occupancy, and the analysis of such measurements, the existence of acoustical deficiencies has been confirmed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Al-Madinah%20Holy%20Mosque" title="Al-Madinah Holy Mosque">Al-Madinah Holy Mosque</a>, <a href="https://publications.waset.org/abstracts/search?q=mosque%20acoustics" title=" mosque acoustics"> mosque acoustics</a>, <a href="https://publications.waset.org/abstracts/search?q=speech%20intelligibility" title=" speech intelligibility"> speech intelligibility</a>, <a href="https://publications.waset.org/abstracts/search?q=worship%20sound" title=" worship sound"> worship sound</a> </p> <a href="https://publications.waset.org/abstracts/97808/assessment-of-the-occupancys-effect-on-speech-intelligibility-in-al-madinah-holy-mosque" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97808.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">43</span> A Proposed Program for Developing Some Concepts to the Nursery Children in Egypt Using Artistic Activities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ebtehag%20Tolba">Ebtehag Tolba</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Mousa"> Ahmed Mousa</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Abd%20El-Salam"> Mohamed Abd El-Salam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study presents a proposed program for nursery school children in Egypt.

Besides, their effects as powder and antioxidant extracts addition on refined sunflower oil stability as natural antioxidants were evaluated. Total polyphenol contents as total phenols, total carotenoids and total tannins were 353.93mg/100g (gallic acid), 10.62mg/100g (carotenoids) and 83.33mg/100g (tannic acid), respectively in licorice, while in carob, it was 186.07, 18.66 and 106.67, respectively. Polyphenol compounds of the studied licorice and carob extracts were determined and identified by HPLC. The stability of refined sunflower oil (which determined by peroxide value and Rancimat) was increased with increasing the level of polyphenols extracts addition. Also, our study shows the effect of addition of these polyphenols extracts to El-mewled El-nabawy sweets fortified by full cream milk powder (sesames and folia). We found that, licorice and carob as powder and polyphenols extracts were delayed the rancidity of sesame and peanut significantly. That encourages using licorice and carob as powder and polyphenols extracts as a good natural antioxidants source instead of synthetic antioxidants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=licorice" title="licorice">licorice</a>, <a href="https://publications.waset.org/abstracts/search?q=carob" title=" carob"> carob</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20antioxidants" title=" natural antioxidants"> natural antioxidants</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20activity" title=" antioxidant activity"> antioxidant activity</a>, <a href="https://publications.waset.org/abstracts/search?q=applications" title=" applications"> applications</a> </p> <a href="https://publications.waset.org/abstracts/8512/extraction-and-identification-of-natural-antioxidants-from-liquorices-glycyrrhiza-glabra-and-carob-ceratonia-siliqua-and-its-application-in-el-mewled-el-nabawy-sweets-sesames-and-folia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8512.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">436</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">41</span> Nematodes, Rotifers, Tardigrades and Diatoms as Vehicles for the Panspermic Transfer of Microbes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sulamain%20Alharbi">Sulamain Alharbi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Khiyami"> Mohammad Khiyami</a>, <a href="https://publications.waset.org/abstracts/search?q=Reda%20Amasha"> Reda Amasha</a>, <a href="https://publications.waset.org/abstracts/search?q=Bassam%20Al-Johny"> Bassam Al-Johny</a>, <a href="https://publications.waset.org/abstracts/search?q=Hesham%20Khalil"> Hesham Khalil</a>, <a href="https://publications.waset.org/abstracts/search?q=Milton%20Wainwrigh"> Milton Wainwrigh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nematodes, Rotifers and Tardigrades (NRT) are extreme-tolerant invertebrates which can survive long periods of stasis brought about by extreme drying and cold. They can also resist the effects of UV radiation, and as a result could act as vehicles for the panspermic transfer of microorganisms. Here we show that NRT contain a variety of bacteria and fungi within their bodies in which environment they could be protected from the extremes of the space and released into new cosmic environments. Diatoms were also shown to contain viable alga and Escherichia coli and so could also act as panspermic vehicles for the transfer of these and perhaps other microbes through space. Although not studied here, NRT, and possibly diatoms, also carry protozoa and viruses within their bodies and could act as vehicles for the panspermic transfer of an even wider range of microbes than shown here. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=extromophiles" title="extromophiles">extromophiles</a>, <a href="https://publications.waset.org/abstracts/search?q=diatoms" title=" diatoms"> diatoms</a>, <a href="https://publications.waset.org/abstracts/search?q=panspermia" title=" panspermia"> panspermia</a>, <a href="https://publications.waset.org/abstracts/search?q=survival%20in%20space" title=" survival in space"> survival in space</a> </p> <a href="https://publications.waset.org/abstracts/3350/nematodes-rotifers-tardigrades-and-diatoms-as-vehicles-for-the-panspermic-transfer-of-microbes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3350.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">557</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">40</span> A Proposed Approach for Emotion Lexicon Enrichment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amr%20Mansour%20Mohsen">Amr Mansour Mohsen</a>, <a href="https://publications.waset.org/abstracts/search?q=Hesham%20Ahmed%20Hassan"> Hesham Ahmed Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Amira%20M.%20Idrees"> Amira M.

Pegylated liposomes were used to encapsulate calcein and then release this model drug when 20-kHz, 40-kHz, 1-MHz and 3-MHz ultrasound were applied at different acoustic power densities. Fluorescence techniques were then used to measure the percent drug release of calcein from these targeted liposomes. Results showed that as the power density increases, at the four frequencies studied, the release of calcein also increased. Based on these results, we believe that ultrasound can be used to increase the rate and amount of chemotherapeutics release from liposomes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=liposomes" title="liposomes">liposomes</a>, <a href="https://publications.waset.org/abstracts/search?q=calcein%20release" title=" calcein release"> calcein release</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20frequency%20ultrasound" title=" high frequency ultrasound"> high frequency ultrasound</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20frequency%20ultrasound" title=" low frequency ultrasound"> low frequency ultrasound</a>, <a href="https://publications.waset.org/abstracts/search?q=fluorescence%20techniques" title=" fluorescence techniques"> fluorescence techniques</a> </p> <a href="https://publications.waset.org/abstracts/24679/release-of-calcein-from-liposomes-using-low-and-high-frequency-ultrasound" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24679.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">424</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">38</span> Experimental and Numerical Investigation of Flow Control Using a Novel Active Slat </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Basman%20Elhadidi">Basman Elhadidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Islam%20Elqatary"> Islam Elqatary</a>, <a href="https://publications.waset.org/abstracts/search?q=Osama%20Saaid"> Osama Saaid</a>, <a href="https://publications.waset.org/abstracts/search?q=Hesham%20Othman"> Hesham Othman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An active slat is developed to increase the lift and delay the separation for a DU96-W180 airfoil.

Jordan can be regarded with a relatively high potential for waste water recycling and reuse. The main purpose of this paper was to investigate the removal of Total suspended solids (TSS) and chemical oxygen demand (COD) for olive mill waste water (OMW) by the electrocoagulation (EC) process. In the combination of electrocoagulation by using coupled iron–aluminum electrodes the optimum working pH was found to be in range 6. The efficiency of the electrocoagulation process allowed removal of TSS and COD about 82.5% and 47.5% respectively at 45 mA/cm2 after 70 minutes by using coupled iron–aluminum electrodes. These results showed that the optimum TSS and COD removal was obtained at the optimum experimental parameters such as current density, pH, and reaction time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=olive%20mill%20wastewater" title="olive mill wastewater">olive mill wastewater</a>, <a href="https://publications.waset.org/abstracts/search?q=electrode" title=" electrode"> electrode</a>, <a href="https://publications.waset.org/abstracts/search?q=electrocoagulation%20%28EC%29" title=" electrocoagulation (EC)"> electrocoagulation (EC)</a>, <a href="https://publications.waset.org/abstracts/search?q=TSS" title=" TSS"> TSS</a>, <a href="https://publications.waset.org/abstracts/search?q=COD" title=" COD"> COD</a> </p> <a href="https://publications.waset.org/abstracts/25362/treatment-of-olive-mill-wastewater-by-electrocoagulation-processes-and-water-resources-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25362.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">393</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">35</span> Power Series Solution to Sliding Velocity in Three-Dimensional Multibody Systems with Impact and Friction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hesham%20A.%20Elkaranshawy">Hesham A.

No analytical solutions have been obtained before for this highly nonlinear system. Hence, a power series solution is proposed. Since the validity of this solution is limited to its convergence zone, a suitable time step is chosen and at the end of it a new series solution is constructed. For a case study, the trajectory of the sliding velocity using the proposed method is built using 6 time steps, which coincides with a Runge-Kutta solution using 38 time steps. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=impact%20with%20friction" title="impact with friction">impact with friction</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20ordinary%20differential%20equations" title=" nonlinear ordinary differential equations"> nonlinear ordinary differential equations</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20series%20solutions" title=" power series solutions"> power series solutions</a>, <a href="https://publications.waset.org/abstracts/search?q=rough%20collision" title=" rough collision"> rough collision</a> </p> <a href="https://publications.waset.org/abstracts/37962/power-series-solution-to-sliding-velocity-in-three-dimensional-multibody-systems-with-impact-and-friction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37962.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">488</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">34</span> Effect of Robot Configuration Parameters, Masses and Friction on Painlevé Paradox for a Sliding Two-Link (P-R) Robot</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hassan%20Mohammad%20Alkomy">Hassan Mohammad Alkomy</a>, <a href="https://publications.waset.org/abstracts/search?q=Hesham%20Elkaranshawy"> Hesham Elkaranshawy</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Ibrahim%20Ashour"> Ahmed Ibrahim Ashour</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Tawfik%20Mohamed"> Khaled Tawfik Mohamed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For a rigid body sliding on a rough surface, a range of uncertainty or non-uniqueness of solution could be found, which is termed: Painlevé paradox.

There are different types of security attacks that limit the range of the RFID applications. For example, deploying the RFID networks in insecure environments could make the RFID system vulnerable to many types of attacks such as spoofing attack, location traceability attack, physical attack and many more. Therefore, security is often an important requirement for RFID systems. In this paper, RFID mutual authentication protocol is implemented based on mobile agent technology and timestamp, which are used to provide strong authentication and integrity assurances to both the RFID readers and their corresponding RFID tags. The integration of mobile agent technology and timestamp provides promising results towards achieving this goal and towards reducing the security threats in RFID systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=RFID" title="RFID">RFID</a>, <a href="https://publications.waset.org/abstracts/search?q=security" title=" security"> security</a>, <a href="https://publications.waset.org/abstracts/search?q=authentication%20protocols" title=" authentication protocols"> authentication protocols</a>, <a href="https://publications.waset.org/abstracts/search?q=privacy" title=" privacy"> privacy</a>, <a href="https://publications.waset.org/abstracts/search?q=agent-based%20architecture" title=" agent-based architecture"> agent-based architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=time-stamp" title=" time-stamp"> time-stamp</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20signature" title=" digital signature"> digital signature</a> </p> <a href="https://publications.waset.org/abstracts/39871/efficient-and-timely-mutual-authentication-scheme-for-rfid-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39871.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">269</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">31</span> Shipboard Power Plant Design as Senior Design Project</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hesham%20Shaalan">Hesham Shaalan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Senior design projects teach students many important skills.

Geologists use the term "marble" to refer to metamorphosed limestone; however, stonemasons use the term more broadly to encompass unmetamorphised limestone. Marble is commonly used for sculpture and as a building material. The marble has many uses; one of them is using the white marble that has been prized for its use in sculptures since classical times. This preference has to do with its softness, relative isotropy and homogeneity, and a relative resistance to shattering. Another use of it is the construction marble which is “a stone which is composed of calcite, dolomite or serpentine which is capable of taking a polish” Marble Institute of America. This report focuses most about the marble in Jordan and its properties: rock definition, physical properties, the marble occurrences in Jordan, types of Jordanian marble and their prices and test done on this marble. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=marble" title="marble">marble</a>, <a href="https://publications.waset.org/abstracts/search?q=metamorphic" title=" metamorphic"> metamorphic</a>, <a href="https://publications.waset.org/abstracts/search?q=non-foliated" title=" non-foliated"> non-foliated</a>, <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title=" compressive strength"> compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=recrystallized" title=" recrystallized"> recrystallized</a>, <a href="https://publications.waset.org/abstracts/search?q=Moh%E2%80%99s%20hardness" title=" Moh’s hardness"> Moh’s hardness</a>, <a href="https://publications.waset.org/abstracts/search?q=abrasion" title=" abrasion"> abrasion</a>, <a href="https://publications.waset.org/abstracts/search?q=absorption" title=" absorption"> absorption</a>, <a href="https://publications.waset.org/abstracts/search?q=modulus%20of%20rupture" title=" modulus of rupture"> modulus of rupture</a>, <a href="https://publications.waset.org/abstracts/search?q=porosity" title=" porosity"> porosity</a> </p> <a href="https://publications.waset.org/abstracts/30419/the-engineering-properties-of-jordanian-marble" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30419.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">373</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">29</span> Sliding Velocity in Impact with Friction in Three-Dimensional Multibody Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hesham%20A.%20Elkaranshawy">Hesham A.

In this work, all these possible sliding behaviors during impact are identified, conditions leading to each behavior are specified, and an appropriate numerical procedure is suggested. A case of a four-degrees-of-freedom spatial robot that collides with its environment is investigated. The phase portrait of the tangential velocity, which presents the flow trajectories for different initial conditions, is calculated. Using the coefficient of friction as a control parameter, few phase portraits are drawn, each for a specific value of this coefficient.

These datasets consist of multiple modalities, each of which has a different representation, distribution, scale, and density. Multimodal fusion is the concept of integrating information from multiple modalities in a joint representation with the goal of predicting an outcome through a classification task or regression task. In this paper, multimodal fusion techniques are classified into two main classes: model-agnostic techniques and model-based approaches. It provides a comprehensive study of recent research in each class and outlines the benefits and limitations of each of them. Furthermore, the audiovisual speech recognition task is expressed as a case study of multimodal data fusion approaches, and the open issues through the limitations of the current studies are presented.

The glass waste is generated in a huge amount which can make one of its disposal in concrete industry effective not only as a green solution but also as an advantage to enhance the performance of mechanical properties and durability of concrete. This article reports the performance of concrete specimens containing different percentages of milled glass waste as a partial replacement of cement (Powder), when they are subject to cycles of freezing and thawing. The tests were conducted on 75-mm cubes and 75 x 75 x 300-mm prisms. Compressive strength based on laboratory testing and non-destructive ultrasonic pulse velocity test were performed during the action of freezing-thawing cycles (F/T). The results revealed that the incorporation of glass waste in concrete mixtures is not only feasible but also showed generally better strength and durability performance than control concrete mixture. It may be said that the recycling of waste glass in concrete mixes is not only a disposal way, but also it can be an exploitation in concrete industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=durability" title="durability">durability</a>, <a href="https://publications.waset.org/abstracts/search?q=glass%20waste" title=" glass waste"> glass waste</a>, <a href="https://publications.waset.org/abstracts/search?q=freeze-thaw%20cycles" title=" freeze-thaw cycles"> freeze-thaw cycles</a>, <a href="https://publications.waset.org/abstracts/search?q=non-destructive%20test" title=" non-destructive test"> non-destructive test</a> </p> <a href="https://publications.waset.org/abstracts/31024/the-feasibility-of-using-milled-glass-wastes-in-concrete-to-resist-freezing-thawing-action" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31024.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">376</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">25</span> Clinical and Molecular Characterization of Mycoplasmosis in Sheep in Egypt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Walid%20Mousa">Walid Mousa</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Nayel"> Mohamed Nayel</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Zaghawa"> Ahmed Zaghawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Akram%20Salama"> Akram Salama</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20El-Sify"> Ahmed El-Sify</a>, <a href="https://publications.waset.org/abstracts/search?q=Hesham%20Rashad"> Hesham Rashad</a>, <a href="https://publications.waset.org/abstracts/search?q=Dina%20El-Shafey"> Dina El-Shafey</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mycoplasmosis in small ruminants constitutes a serious contagious problem in smallholders causing severe economic losses worldwide. This study was conducted to determine the clinical, Minimum Inhibitory Concentration (MIC) and molecular characterization of Mycoplasma species associated in sheep breeding herds in Menoufiya governorate, Egypt. Out of the examination of 400 sheep, 104 (26%) showed respiratory manifestations, nasal discharges, cough and conjunctivitis with systemic body reaction. Meanwhile, out of these examined sheep, only 56 (14%) were positive for mycoplasma isolation onto PPLO(Pleuropneumonia-like organisms) specific medium. The MIC for evaluating the efficacy of sensitivity of Mycoplasma isolates against different antibiotics groups revealed that both the Linospectin and Tylosin with 2ug, 0.25ug/ml concentration were the most effective antibiotics for Mycoplasma isolates. The application of PCR was the rapid, specific and sensitive molecular approach for detection of M. ovipneumoniae, and M. arginine at 390 and 326 bp, respectively, in all tested isolates. In conclusion, the diagnosis of Mycoplsamosis in sheep is important to achieve effective control measures and minimizing the disease dissemination among sheep herds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MIC" title="MIC">MIC</a>, <a href="https://publications.waset.org/abstracts/search?q=mycoplasmosis" title=" mycoplasmosis"> mycoplasmosis</a>, <a href="https://publications.waset.org/abstracts/search?q=PCR" title=" PCR"> PCR</a>, <a href="https://publications.waset.org/abstracts/search?q=sheep" title=" sheep"> sheep</a> </p> <a href="https://publications.waset.org/abstracts/136307/clinical-and-molecular-characterization-of-mycoplasmosis-in-sheep-in-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136307.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">228</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">24</span> Reduction of Multiple User Interference for Optical CDMA Systems Using Successive Interference Cancellation Scheme</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tawfig%20Eltaif">Tawfig Eltaif</a>, <a href="https://publications.waset.org/abstracts/search?q=Hesham%20A.%20Bakarman"> Hesham A.

In this article, we aim to mitigate this problem by studying an interference cancellation scheme called successive interference cancellation (SIC) scheme. This scheme will be tested on two different detection schemes, spectral amplitude coding (SAC) and direct detection systems (DS), using partial modified prime (PMP) as the signature codes. It was found that SIC scheme based on both SAC and DS methods had a potential to suppress the intensity noise, that is to say, it can mitigate MUI noise. Furthermore, SIC/DS scheme showed much lower bit error rate (BER) performance relative to SIC/SAC scheme for different magnitude of effective power. Hence, many more users can be supported by SIC/DS receiver system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optical%20code-division%20multiple%20access%20%28OCDMA%29" title="optical code-division multiple access (OCDMA)">optical code-division multiple access (OCDMA)</a>, <a href="https://publications.waset.org/abstracts/search?q=successive%20interference%20cancellation%20%28SIC%29" title=" successive interference cancellation (SIC)"> successive interference cancellation (SIC)</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20user%20interference%20%28MUI%29" title=" multiple user interference (MUI)"> multiple user interference (MUI)</a>, <a href="https://publications.waset.org/abstracts/search?q=spectral%20amplitude%20coding%20%28SAC%29" title=" spectral amplitude coding (SAC)"> spectral amplitude coding (SAC)</a>, <a href="https://publications.waset.org/abstracts/search?q=partial%20modified%20prime%20code%20%28PMP%29" title=" partial modified prime code (PMP)"> partial modified prime code (PMP)</a> </p> <a href="https://publications.waset.org/abstracts/33603/reduction-of-multiple-user-interference-for-optical-cdma-systems-using-successive-interference-cancellation-scheme" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33603.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">521</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">23</span> Active Bio-Packaging Fabricated from Coated Bagasse Papers with Polystyrene Nanocomposites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hesham%20%20Moustafa">Hesham Moustafa</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20M.%20Youssef"> Ahmed M.

Thus, this study revealed that the by-product bagasse papers (BPs) derived from sugarcane waste can be decorated with a thin layer of polystyrene (PS) nanocomposites using the spreading approach.Three variable concentrations of TiO2 nanoparticles (i.e. 0.5, 1.0, 1.5 wt.%) were used to fabricate PS nanocomposites. The morphology of coated BP-PS biofilms was examined by X-ray diffraction, Fourier transferred Infrared spectroscopy (FT-IR), and scanning electron microscopy (SEM). Moreover, other measurements such as mechanical, thermal stability, flammability, wettability by the contact angle, water vapor, and gas barrier properties were carried out on the fabricated BP-PS biofilms. Most outcomes showed that the major properties were enhanced when the PS nanocomposites were implemented. The use of 1.5 wt.% TiO2 in PS nanocomposite for coated BP-PS biofilm increased the tensile stress by ~ 217 % compared to uncoated BP film. Furthermore, the rate of burning for BP-PS-1.5% film was reduced to ~ 33 mm/min because of the crystallinity of PS and the barrier effect provided by TiO₂ NPs. These coated sheets provide a promising candidate for use in advanced packaging applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bagasse%20paper" title="bagasse paper">bagasse paper</a>, <a href="https://publications.waset.org/abstracts/search?q=polystyrene%20nanocomposites" title=" polystyrene nanocomposites"> polystyrene nanocomposites</a>, <a href="https://publications.waset.org/abstracts/search?q=TiO2%20nanoparticles" title=" TiO2 nanoparticles"> TiO2 nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=active%20packaging" title=" active packaging"> active packaging</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=flammability" title=" flammability"> flammability</a> </p> <a href="https://publications.waset.org/abstracts/152558/active-bio-packaging-fabricated-from-coated-bagasse-papers-with-polystyrene-nanocomposites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152558.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">85</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">22</span> Evaluating Portfolio Performance by Highlighting Network Property and the Sharpe Ratio in the Stock Market</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zahra%20Hatami">Zahra Hatami</a>, <a href="https://publications.waset.org/abstracts/search?q=Hesham%20Ali"> Hesham Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Volkman"> David Volkman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Selecting a portfolio for investing is a crucial decision for individuals and legal entities. In the last two decades, with economic globalization, a stream of financial innovations has rushed to the aid of financial institutions. The importance of selecting stocks for the portfolio is always a challenging task for investors. This study aims to create a financial network to identify optimal portfolios using network centralities metrics. This research presents a community detection technique of superior stocks that can be described as an optimal stock portfolio to be used by investors. By using the advantages of a network and its property in extracted communities, a group of stocks was selected for each of the various time periods. The performance of the optimal portfolios compared to the famous index. Their Sharpe ratio was calculated in a timely manner to evaluate their profit for making decisions. The analysis shows that the selected potential portfolio from stocks with low centrality measurement can outperform the market; however, they have a lower Sharpe ratio than stocks with high centrality scores. In other words, stocks with low centralities could outperform the S&P500 yet have a lower Sharpe ratio than high central stocks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=portfolio%20management%20performance" title="portfolio management performance">portfolio management performance</a>, <a href="https://publications.waset.org/abstracts/search?q=network%20analysis" title=" network analysis"> network analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=centrality%20measurements" title=" centrality measurements"> centrality measurements</a>, <a href="https://publications.waset.org/abstracts/search?q=Sharpe%20ratio" title=" Sharpe ratio"> Sharpe ratio</a> </p> <a href="https://publications.waset.org/abstracts/148342/evaluating-portfolio-performance-by-highlighting-network-property-and-the-sharpe-ratio-in-the-stock-market" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148342.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">21</span> Chipless RFID Capacity Enhancement Using the E-pulse Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Haythem%20H.%20Abdullah">Haythem H.

The chipless RFID tag reduces the cost to a large extent but at the expense of utilizing the spectrum. The reduction of the cost of chipless RFID is due to the absence of the chip itself. The identification is done by utilizing the spectrum in such a way that the frequency response of the tags consists of some resonance frequencies that represent the bits. The system capacity is decided by the number of resonators within the pre-specified band. It is important to find a solution to enhance the spectrum utilization when using chipless RFID. Target identification is a process that results in a decision that a specific target is present or not. Several target identification schemes are present, but one of the most successful techniques in radar target identification in the oscillatory region is the extinction pulse technique (E-Pulse). The E-Pulse technique is used to identify targets via its characteristics (natural) modes. By introducing an innovative solution for chipless RFID reader and tag designs, the spectrum utilization goes to the optimum case. In this paper, a novel capacity enhancement scheme based on the E-pulse technique is introduced to improve the performance of the chipless RFID system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chipless%20RFID" title="chipless RFID">chipless RFID</a>, <a href="https://publications.waset.org/abstracts/search?q=E-pulse" title=" E-pulse"> E-pulse</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20modes" title=" natural modes"> natural modes</a>, <a href="https://publications.waset.org/abstracts/search?q=resonators" title=" resonators"> resonators</a> </p> <a href="https://publications.waset.org/abstracts/172234/chipless-rfid-capacity-enhancement-using-the-e-pulse-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172234.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">20</span> Coordinated Renewal Planning of Civil Infrastructure Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hesham%20Osman">Hesham Osman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The challenges facing aging urban infrastructure systems require a more holistic and comprehensive approach to their management. The large number of urban infrastructure renewal activities occurring in cities throughout the world leads to social, economic and environmental impacts on the communities in its vicinity. As such, a coordinated effort is required to streamline these activities. This paper presents a framework to enable temporal (time-based) coordination of water, sewer and road intervention activities. Intervention activities include routine maintenance, renewal, and replacement of physical assets. The coordination framework considers 1) Life-cycle costs, 2) Infrastructure level-of-service, and 3) Risk exposure to system operators. The model enables infrastructure asset managers to trade-off options of delaying versus bringing forward intervention activities of one system in order to be executed in conjunction with another co-located system in the right-of-way. The framework relies on a combination of meta-heuristics and goal-based optimization. In order to demonstrate the applicability of the framework, a case study for a major infrastructure corridor in Cairo, Egypt is taken as an example. Results show that the framework can be scaled-up to include other infrastructure systems located in the right-of-way like electricity, gas and telecom, provided that information can be shared among these entities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=infrastructure" title="infrastructure">infrastructure</a>, <a href="https://publications.waset.org/abstracts/search?q=rehabilitation" title=" rehabilitation"> rehabilitation</a>, <a href="https://publications.waset.org/abstracts/search?q=construction" title=" construction"> construction</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a> </p> <a href="https://publications.waset.org/abstracts/41878/coordinated-renewal-planning-of-civil-infrastructure-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41878.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">19</span> Combined Orthodontic and Restorative Management of Complex Cases: Concepts and Case Reports</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Awais%20Ali">Awais Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Hesham%20Ali"> Hesham Ali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The absence of teeth through either premature loss or developmental absence is a common condition with potentially severe impact on affected individuals. Management of these cases presents a clinical challenge which may be difficult to resolve given the effects of tooth loss or hypodontia over the course of a patient’s lifetime. Treatment of such cases is often best provided by a multi-disciplinary team, where the patient’s expectations and care delivery can be optimally managed. Orthodontic treatment is often used to prepare the dentition in advance of restorative replacement of missing teeth. Conversely, the placement of implants may precede the delivery of orthodontic treatment and indeed may function as an adjunctive orthodontic procedure. We discuss the use of both approaches here and illustrate their clinical implementation with two case reports. The first case demonstrates the use of fixed appliances to prepare the mouth for an opposing implant-retained complete denture. A second case demonstrates the use of implant-retained crowns to provide orthodontic anchorage in a partially dentate patient. We propose that complex cases such as these should always be planned and treated by a multi-disciplinary team in order to optimise the delivery of care, patient experience, and treatment outcome. The presented cases add to the body of evidence in this area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=orthodontics" title="orthodontics">orthodontics</a>, <a href="https://publications.waset.org/abstracts/search?q=dental%20implantology" title=" dental implantology"> dental implantology</a>, <a href="https://publications.waset.org/abstracts/search?q=hypodontia" title=" hypodontia"> hypodontia</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-disciplinary" title=" multi-disciplinary"> multi-disciplinary</a> </p> <a href="https://publications.waset.org/abstracts/111373/combined-orthodontic-and-restorative-management-of-complex-cases-concepts-and-case-reports" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111373.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">128</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">18</span> Antibacterial Activity of Salvadora persica Extracts against Oral Cavity Bacteria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sulaiman%20A.%20Alrumman">Sulaiman A.

Miswak is derived from the plant arak (Salvadora persica). It is used by Muslim people as a natural product for the cleansing of teeth, to ensure oral and dental hygiene. This study was designed to evaluate the antimicrobial effects of ethanol, methanol, and ethanol/methanol extracts of miswak against three bacterial pathogens of the oral cavity. The pathogens were isolated from the oral cavity of volunteers/patients and were identified on the basis of 16S rRNA gene amplification data. Sequence comparisons were made with 16S rRNA gene sequences available in the GenBank database. The results of sequence alignment and phylogenetic analysis identified the three pathogens as being Staphylococcus aureus strain KKU-020, Enterococcus faecalis strain KKU-021 and Klebsiella pneumoniae strain KKU-022. All miswak extracts showed powerful antimicrobial activity against the three pathogens. The maximum zone of inhibition (40.67±0.88 mm) was observed against E. faecalis with ethanolic extracts whilst methanolic extracts showed the minimum zone of inhibition (10.33±0.88 mm) against K. pneumonia KKU-022. Based on the significant effects of the miswak extracts against the oral cavity pathogens in our study, we recommend that miswak is to be used as a dental hygiene method to prevent tooth caries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibacterial" title="antibacterial">antibacterial</a>, <a href="https://publications.waset.org/abstracts/search?q=miswak" title=" miswak"> miswak</a>, <a href="https://publications.waset.org/abstracts/search?q=Salvadora%20persica" title=" Salvadora persica"> Salvadora persica</a>, <a href="https://publications.waset.org/abstracts/search?q=oral%20cavity%20pathogens" title=" oral cavity pathogens "> oral cavity pathogens </a> </p> <a href="https://publications.waset.org/abstracts/12577/antibacterial-activity-of-salvadora-persica-extracts-against-oral-cavity-bacteria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12577.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">17</span> Simulation IDM for Schedule Generation of Slip-Form Operations </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hesham%20A.%20Khalek">Hesham A.

On the other hand, Discrete-event simulation concepts can be applied to simulate and analyze construction operations and to efficiently support construction scheduling. Nevertheless, preparation of input data for construction simulation is very challenging, time-consuming and human prone-error source. Therefore, to enhance the beneﬁts of using DES in construction scheduling, this study proposes an integrated module to establish a framework for automating the generation of time schedules and decision support for Slipform construction projects, particularly through the project feasibility study phase by using data exchange between project data stored in an Intermediate database, DES and Scheduling software. Using the stored information, proposed system creates construction tasks attribute [e.g. activities durations, material quantities and resources amount], then DES uses all the given information to create a proposal for the construction schedule automatically. This research is considered a demonstration of a flexible Slipform project modeling, rapid scenario-based planning and schedule generation approach that may be of interest to both practitioners and researchers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=discrete-event%20simulation" title="discrete-event simulation">discrete-event simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling"> modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=construction%20planning" title=" construction planning"> construction planning</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20exchange" title=" data exchange"> data exchange</a>, <a href="https://publications.waset.org/abstracts/search?q=scheduling%20generation" title=" scheduling generation"> scheduling generation</a>, <a href="https://publications.waset.org/abstracts/search?q=EZstrobe" title=" EZstrobe "> EZstrobe </a> </p> <a href="https://publications.waset.org/abstracts/34281/simulation-idm-for-schedule-generation-of-slip-form-operations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34281.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">376</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">16</span> Influence of Loading Pattern and Shaft Rigidity on Laterally Loaded Helical Piles in Cohesion-Less Soil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Hesham%20Hamdy%20Abdelmohsen">Mohamed Hesham Hamdy Abdelmohsen</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Shawky%20Abdul%20Aziz"> Ahmed Shawky Abdul Aziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Mona%20Fawzy%20Al-Daghma"> Mona Fawzy Al-Daghma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Helical piles are widely used as axially and laterally loaded deep foundations. Once they are required to resist bearing combined loads (BCLs), as axial compression and lateral thrust, different behaviour is expected, necessitating further investigation. The objective of the present article is to clarify the behaviour of a single helical pile of different shaft rigidity embedded in cohesion-less soil and subjected to simultaneous or successive loading patterns of BCLs. The study was first developed analytically and extended numerically. The numerical analysis was further verified through a laboratory experimental program on a set of helical pile models. The results indicate highly interactive effects of the studied parameters, but it is obviously confirmed that the pile performance increases with both the increase of shaft rigidity and the change of BCLs loading pattern from simultaneous to successive. However, it is noted that the increase of vertical load does not always enhance the lateral capacity but may cause a decrement in lateral capacity, as observed with helical piles of flexible shafts. This study provides insightful information for the design of helical piles in structures loaded by complex sequence of forces, wind turbines, and industrial shafts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=helical%20pile" title="helical pile">helical pile</a>, <a href="https://publications.waset.org/abstracts/search?q=lateral%20loads" title=" lateral loads"> lateral loads</a>, <a href="https://publications.waset.org/abstracts/search?q=combined%20loads" title=" combined loads"> combined loads</a>, <a href="https://publications.waset.org/abstracts/search?q=cohesion-less%20soil" title=" cohesion-less soil"> cohesion-less soil</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical" title=" analytical"> analytical</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical" title=" numerical"> numerical</a> </p> <a href="https://publications.waset.org/abstracts/186412/influence-of-loading-pattern-and-shaft-rigidity-on-laterally-loaded-helical-piles-in-cohesion-less-soil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186412.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">64</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> Tuning of Kalman Filter Using Genetic Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hesham%20Abdin">Hesham Abdin</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Zakaria"> Mohamed Zakaria</a>, <a href="https://publications.waset.org/abstracts/search?q=Talaat%20Abd-Elmonaem"> Talaat Abd-Elmonaem</a>, <a href="https://publications.waset.org/abstracts/search?q=Alaa%20El-Din%20Sayed%20Hafez"> Alaa El-Din Sayed Hafez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Kalman filter algorithm is an estimator known as the workhorse of estimation. It has an important application in missile guidance, especially in lack of accurate data of the target due to noise or uncertainty. In this paper, a Kalman filter is used as a tracking filter in a simulated target-interceptor scenario with noise. It estimates the position, velocity, and acceleration of the target in the presence of noise. These estimations are needed for both proportional navigation and differential geometry guidance laws. A Kalman filter has a good performance at low noise, but a large noise causes considerable errors leads to performance degradation. Therefore, a new technique is required to overcome this defect using tuning factors to tune a Kalman filter to adapt increasing of noise. The values of the tuning factors are between 0.8 and 1.2, they have a specific value for the first half of range and a different value for the second half. they are multiplied by the estimated values. These factors have its optimum values and are altered with the change of the target heading. A genetic algorithm updates these selections to increase the maximum effective range which was previously reduced by noise. The results show that the selected factors have other benefits such as decreasing the minimum effective range that was increased earlier due to noise. In addition to, the selected factors decrease the miss distance for all ranges of this direction of the target, and expand the effective range which leads to increase probability of kill. <p
