Conjunctival and cloacal swabs from 54 captive psittacine birds presented at veterinary clinics were collected to determine the prevalence of C. psittaci in domestic birds in Isfahan. Samples were collected during 2014 from a total of 10 different species of parrots, with African gray(33), Cockatiel lutino(3), Cockatiel gray(2), Cockatiel cinnamon(1), Pearl cockatiel(6), Timneh African grey(1), Ringneck parakeet(2), Melopsittacus undulatus(1), Alexander parakeet(2), Green Parakeet(3) being the most representative species sampled. C. psittaci was detected in 27 (50%) birds using molecular detection (PCR) method. The detection of this bacterium in captive psittacine birds shows that there is a potential risk for human whom has a direct contact and there is a possibility of infecting other birds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chlamydophila%20psittaci" title="chlamydophila psittaci">chlamydophila psittaci</a>, <a href="https://publications.waset.org/abstracts/search?q=psittacine%20birds" title=" psittacine birds"> psittacine birds</a>, <a href="https://publications.waset.org/abstracts/search?q=PCR" title=" PCR"> PCR</a>, <a href="https://publications.waset.org/abstracts/search?q=Isfahan" title=" Isfahan"> Isfahan</a> </p> <a href="https://publications.waset.org/abstracts/39281/detection-and-identification-of-chlamydophila-psittaci-in-asymptomatic-and-symptomatic-parrots-in-isfahan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39281.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">371</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">316</span> Enhancing Predictive Accuracy in Pharmaceutical Sales through an Ensemble Kernel Gaussian Process Regression Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shahin%20Mirshekari">Shahin Mirshekari</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammadreza%20Moradi"> Mohammadreza Moradi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Jafari"> Hossein Jafari</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Jafari"> Mehdi Jafari</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Ensaf"> Mohammad Ensaf</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research employs Gaussian Process Regression (GPR) with an ensemble kernel, integrating Exponential Squared, Revised Matern, and Rational Quadratic kernels to analyze pharmaceutical sales data.

The ensemble kernel demonstrated superior performance in predictive accuracy, achieving an R² score near 1.0, and significantly lower values in MSE, MAE, and RMSE.

The aim is to protect these structures from serious damages while subjected to impact loads, or to minimize human injuries while collision is occurred in transportation systems. These energy-absorbing devices can dissipate kinetic energy in a wide variety of ways like friction, facture, plastic bending, crushing, cyclic plastic deformation and metal cutting. On the other hand, various structures may be used as collapsible energy absorbers. Metallic cylindrical tubes have attracted much more attention due to their high stiffness and strength combined with the low weight and ease of manufacturing process. As a matter of fact, favorable crash worthiness characteristics for energy dissipation purposes can be achieved from axial collapse of tubes while they crush progressively in symmetric modes. However, experimental and theoretical results have shown that depending on various parameters such as tube geometry, material properties of tube, boundary and loading conditions, circular tubes buckle in different modes of deformation, namely, diamond and Euler collapsing modes. It is shown that when the tube length is greater than the critical length, the tube deforms in overall Euler buckling mode, which is an inefficient mode of energy absorption and needs to be avoided in crash worthiness applications. This study develops a new method with the aim of improving energy absorption characteristics of long steel circular tubes. Inserting a helical spring into the tubes is proved experimentally to be an efficient solution. In fact when a long tube is subjected to axial compression load, the spring prevents of undesirable Euler or diamond collapsing modes. This is because the spring reinforces the internal wall of tubes and it causes symmetric deformation in tubes. In this research three specimens were prepared and three tests were performed. The dimensions of tubes were selected so that in axial compression load buckling is occurred. In the second and third tests a spring was inserted into tubes and they were subjected to axial compression load in quasi-static and impact loading, respectively. The results showed that in the second and third tests buckling were not happened and the tubes deformed in symmetric modes which are desirable in energy absorption. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20absorption" title="energy absorption">energy absorption</a>, <a href="https://publications.waset.org/abstracts/search?q=circular%20tubes" title=" circular tubes"> circular tubes</a>, <a href="https://publications.waset.org/abstracts/search?q=collapsing%20deformation" title=" collapsing deformation"> collapsing deformation</a>, <a href="https://publications.waset.org/abstracts/search?q=crashworthiness" title=" crashworthiness"> crashworthiness</a> </p> <a href="https://publications.waset.org/abstracts/29420/improving-the-crashworthiness-characteristics-of-long-steel-circular-tubes-subjected-to-axial-compression-by-inserting-a-helical-spring" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29420.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">340</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">310</span> Flow Duration Curve Method to Evaluate Environmental Flow: Case Study of Gharasou River, Ardabil, Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Fuladipanah">Mehdi Fuladipanah</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Jorabloo"> Mehdi Jorabloo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water flow management is one of the most important parts of river engineering.

Multi-terminal DC wind farm topologies are attracting increasing research attempt. With AC/DC converters on the generator side, this topology can be developed into a multi-terminal DC network for wind power collection, which is especially suitable for large-scale offshore wind farms. For wind farms, the topology uses high-voltage direct-current transmission based on voltage-source converters (VSC-HVDC). Therefore, they do not suffer from over currents due to DC cable faults and there is no over current to react to. In this study, the multi-terminal DC wind farm topology is introduced. Then, possible internal DC faults are analyzed according to type and characteristic. Fault over current expressions are given in detail. Under this characteristic analysis, fault detection and detailed protection methods are proposed. Theoretical analysis and PSCAD/EMTDC simulations are provided. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DC%20short%20circuits" title="DC short circuits">DC short circuits</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-terminal%20DC%20wind%20farm%20topologies" title=" multi-terminal DC wind farm topologies"> multi-terminal DC wind farm topologies</a>, <a href="https://publications.waset.org/abstracts/search?q=HVDC%20transmission%20based%20on%20VSC" title=" HVDC transmission based on VSC"> HVDC transmission based on VSC</a>, <a href="https://publications.waset.org/abstracts/search?q=fault%20analysis" title=" fault analysis"> fault analysis</a> </p> <a href="https://publications.waset.org/abstracts/10282/internal-dc-short-circuit-fault-analysis-and-protection-for-vsi-of-wind-power-generation-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10282.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">421</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">304</span> Saudi Arabia and the Yemen War: A Fruitless Struggle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Majid%20Dashtgerd">Majid Dashtgerd</a>, <a href="https://publications.waset.org/abstracts/search?q=Eisa%20Moradi%20Afrapoli"> Eisa Moradi Afrapoli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The “Yemen War” is one of the longest wars of the recent century, which was launched on 26 March 2015 after the Saudi Arabia-led alliance's military intervention in Yemen.

The association of the polymorphisms with growth traits and blood parameters was also examined. Results revealed a g.939A > G SNP (single nucleotide polymorphism) in the exon 2 exhibiting three genotypes: AA, AG, and GG. Statistical analysis indicated that this polymorphism significantly influenced blood triglyceride (P < 0.05) and cholesterol (P < 0.08) levels as well as weaning weight (P < 0.05). Animals with AG genotype had the highest blood triglyceride level and weaning weight while the highest amount of blood cholesterol was observed in animals with GG genotype. On the other hand, no significant effect was observed on birth and fat-tail weight traits. The intron 3 (g.4349A > G) was monomorphic across the studied samples. Lori-Bakhtiari breed showed significantly higher blood triglyceride and cholesterol levels, as also birth and weaning weight compared to Zel breed (P < 0.01). Considering that the literature is bereft of any report on the association study between FABP3 SNPs and sheep growth traits and blood parameters, our findings suggest that the investigated polymorphism might be one of the main genetic factors affecting growth and physiological traits in sheep. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=FABP3%20gene" title="FABP3 gene">FABP3 gene</a>, <a href="https://publications.waset.org/abstracts/search?q=fatness" title=" fatness"> fatness</a>, <a href="https://publications.waset.org/abstracts/search?q=weaning%20weight" title=" weaning weight"> weaning weight</a>, <a href="https://publications.waset.org/abstracts/search?q=blood%20triglyceride" title=" blood triglyceride"> blood triglyceride</a>, <a href="https://publications.waset.org/abstracts/search?q=cholesterol" title=" cholesterol"> cholesterol</a>, <a href="https://publications.waset.org/abstracts/search?q=Zel" title=" Zel"> Zel</a>, <a href="https://publications.waset.org/abstracts/search?q=Lori-Bakhtiari" title=" Lori-Bakhtiari"> Lori-Bakhtiari</a> </p> <a href="https://publications.waset.org/abstracts/28858/fatty-acid-binding-protein-3-gene-polymorphisms-and-their-associations-with-growth-traits-and-blood-parameters-in-two-iranian-sheep-breeds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28858.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">699</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">302</span> Numerical Study of Partial Penetration of PVDs In Soft Clay Soils Treatment Along With Surcharge Preloading (Bangkok Airport Case Study)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Mehdi%20Pardsouie">Mohammad Mehdi Pardsouie</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Mokhberi"> Mehdi Mokhberi</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Mohammad%20Ali%20Zomorodian"> Seyed Mohammad Ali Zomorodian</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Alireza%20Nasehi"> Seyed Alireza Nasehi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the challenging parts of every project, including prefabricated vertical drains (PVDs), is the determination of the depth of installation and its configuration. In this paper, Geostudio 2018 was used for modeling and verification of the full-scale test embankments (TS1, TS2, and TS3), which were constructed to study the effectiveness of PVDs for accelerating the consolidation and dissipation of the excess pore-pressures resulting from fill placement at Bangkok airport. Different depths and scenarios were modeled and the results were compared and analyzed. Since the ultimate goal is attaining pre-determined settlement, the settlement curve under soil embankment was used for the investigation of the results. It was shown that nearly in all cases, the same results and efficiency might be obtained by partial depth installation of PVDs instead of complete full constant length installation. However, it should be mentioned that because of distinct soil characteristics of clay soils and layers properties of any project, further investigation of full-scale test embankments and modeling is needed prior to finalizing the ultimate design by competent geotechnical consultants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=partial%20penetration" title="partial penetration">partial penetration</a>, <a href="https://publications.waset.org/abstracts/search?q=surcharge%20preloading" title=" surcharge preloading"> surcharge preloading</a>, <a href="https://publications.waset.org/abstracts/search?q=excess%20pore%20water%20pressure" title=" excess pore water pressure"> excess pore water pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=Bangkok%20test%20embankments" title=" Bangkok test embankments"> Bangkok test embankments</a> </p> <a href="https://publications.waset.org/abstracts/143189/numerical-study-of-partial-penetration-of-pvds-in-soft-clay-soils-treatment-along-with-surcharge-preloading-bangkok-airport-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143189.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">207</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">301</span> Numerical Simulation of Laser ‎Propagation through Turbulent ‎Atmosphere Using Zernike ‎Polynomials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Moradi%20%E2%80%8E">Mohammad Moradi ‎</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this article, propagation of a laser beam through turbulent ‎atmosphere is evaluated.

It is taken for a generation that; it is important to analyze which combination of values of the explanatory variables -in an econometric method- would point to the simultaneous achievement of the best values of the response variables. In this case, if a certain degree of conflict is viewed among the response variables, we suggest a multiobjective method in order to the results obtained from a regression analysis. In fact, with the use of a multiobjective method, we will have the best decision about the conflicting relationship between the response variables and the optimal solution.

In this approach, we can modulate the original dynamics of the controller and it allows us to determine safety margin and different types of DS to increase the robot’s reactiveness in the face of uncertainty in the localization of the obstacle and especially when robot moves very fast in changeable complex environments. The method is validated in simulation and influence of different autonomous and non-autonomous DS such as limit cycles, and unstable DS on this algorithm and also the position of different obstacles in complex environment is explained. Finally, we describe how the avoidance trajectories can be verified through different parameters such as safety factor. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=limit%20cycles" title="limit cycles">limit cycles</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20dynamical%20system" title=" nonlinear dynamical system"> nonlinear dynamical system</a>, <a href="https://publications.waset.org/abstracts/search?q=real%20time%20obstacle%20avoidance" title=" real time obstacle avoidance"> real time obstacle avoidance</a>, <a href="https://publications.waset.org/abstracts/search?q=DS-based%20controllers" title=" DS-based controllers"> DS-based controllers</a> </p> <a href="https://publications.waset.org/abstracts/13882/real-time-adaptive-obstacle-avoidance-with-ds-method-and-the-influence-of-dynamic-environments-change-on-different-ds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13882.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">389</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">290</span> Study of the Effect of Soil Compaction and Height on Pipe Ovality for Buried Steel Pipe</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Ghodsbin%20Jahromi">Ali Ghodsbin Jahromi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Moradi"> Ehsan Moradi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the numerical study of buried steel pipe in soil is investigated. Buried pipeline under soil weight, after embankment on the pipe leads to ovality of pipe. In this paper also it is considered the percentage of soil compaction, the soil height on the steel pipe and the external load of a mechanical excavator on the steel pipe and finally, the effect of these on the rate of pipe ovality investigated. Furthermore, the effect of the pipes’ thickness on ovality has been investigated. The results show that increasing the percentage of soil compaction has more effect on reducing percentage of ovality, and if the percentage of soil compaction increases, we can use the pipe with less thickness. Finally, ovality rate of the pipe and acceptance criteria of pipe diameter up to yield stress is investigated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pipe%20ovality" title="pipe ovality">pipe ovality</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20compaction" title=" soil compaction"> soil compaction</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element" title=" finite element"> finite element</a>, <a href="https://publications.waset.org/abstracts/search?q=pipe%20thickness" title=" pipe thickness "> pipe thickness </a> </p> <a href="https://publications.waset.org/abstracts/110519/study-of-the-effect-of-soil-compaction-and-height-on-pipe-ovality-for-buried-steel-pipe" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110519.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">152</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">289</span> RANS Simulation of the LNG Ship Squat in Shallow Water</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Nakisa">Mehdi Nakisa</a>, <a href="https://publications.waset.org/abstracts/search?q=Adi%20Maimun"> Adi Maimun</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasser%20M.%20Ahmed"> Yasser M.

The forward motion of the ship induces a relative velocity between the ship and the surrounding water that causes a water level depression in which the ship sinks. The problem of ship squat is one among the crucial factors affecting the navigation of ships in restricted waters. This article investigates the LNG ship squat, its effects on flow streamlines around the ship hull and ship behavior and motion using computational fluid dynamics which is applied by Ansys-Fluent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ship%20squat" title="ship squat">ship squat</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD" title=" CFD"> CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=confined" title=" confined"> confined</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanic" title=" mechanic"> mechanic</a> </p> <a href="https://publications.waset.org/abstracts/4835/rans-simulation-of-the-lng-ship-squat-in-shallow-water" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4835.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">620</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">288</span> The Effect of Urmia-Lake Water on Tensional Strength Concrete with Various Admixtures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hadi%20Barghlame">Hadi Barghlame</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20A.%20Lotfollahi-Yaghin"> M.
