The poetic stories of Asadi in Garshasb-Nameh is contrasted to human psyche according to Jung’s view in psychology which indicated the similarity of poetic structure of stories of Garshasb-Nameh to analytical psychology of Jung. In fact, by studying the stories of this collection the reader travels with him and finds it consistent with the human psyche. To demonstrate this, the story of Jamshid marriage with Kuhrang’s daughter and the story of Garshasb marriage with King’s daughter are selected. These two stories illustrate the poetic structure and the human psyche based on Jung’s analytical psychology perspective. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asadi%20Tusi" title="Asadi Tusi">Asadi Tusi</a>, <a href="https://publications.waset.org/abstracts/search?q=Garshasb-Nameh" title=" Garshasb-Nameh"> Garshasb-Nameh</a>, <a href="https://publications.waset.org/abstracts/search?q=Jung" title=" Jung"> Jung</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical%20psychology" title=" analytical psychology"> analytical psychology</a> </p> <a href="https://publications.waset.org/abstracts/36033/the-structure-of-asadis-poem-and-human-psyche-in-garshasb-nameh-based-on-jungs-perspective" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36033.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">400</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> Regression Analysis of Travel Indicators and Public Transport Usage in Urban Areas</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Moeinaddini">Mehdi Moeinaddini</a>, <a href="https://publications.waset.org/abstracts/search?q=Zohreh%20Asadi-Shekari"> Zohreh Asadi-Shekari</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Zaly%20Shah"> Muhammad Zaly Shah</a>, <a href="https://publications.waset.org/abstracts/search?q=Amran%20Hamzah"> Amran Hamzah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Currently, planners try to have more green travel options to decrease economic, social and environmental problems.

Currently, various methods are proposed for BLOS. These analytical methods however have some drawbacks: they usually assume cyclists as users that can share street facilities with motorized vehicles, it is not easy to link them to design process and they are not easy to follow. In addition, they only support a narrow range of cycling facilities and may not be applicable for all situations. Along this, the current paper introduces various effective design factors for bicycle-friendly streets. This study considers cyclists as users of streets who have special needs and facilities. Therefore, the key factors that influence BLOS based on different cycling facilities that are proposed by developed guidelines and literature are identified. The combination of these factors presents a complete set of effective design factors for bicycle-friendly streets. In addition, the weight of each factor in existing BLOS models is estimated and these effective factors are ranked based on these weights. These factors and their weights can be used in further studies to propose special bicycle-friendly street design model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bicycle%20level%20of%20service" title="bicycle level of service">bicycle level of service</a>, <a href="https://publications.waset.org/abstracts/search?q=bicycle-friendly%20streets" title=" bicycle-friendly streets"> bicycle-friendly streets</a>, <a href="https://publications.waset.org/abstracts/search?q=cycling%20facilities" title=" cycling facilities"> cycling facilities</a>, <a href="https://publications.waset.org/abstracts/search?q=rating%20system" title=" rating system"> rating system</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20streets" title=" urban streets"> urban streets</a> </p> <a href="https://publications.waset.org/abstracts/25020/effective-design-factors-for-bicycle-friendly-streets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25020.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">297</span> Comparison of Chest Weight of Pure and Mixed Races Kabood 30-Day Squab</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sepehr%20Moradi">Sepehr Moradi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Asadi%20Rad"> Mehdi Asadi Rad </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study is to evaluate and compare chest weight of pure and mixed races Kabood 30-day Pigeons to investigate about their sex, race, and some auxiliary variables.

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">290</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">289</span> The Effect of Measurement Distribution on System Identification and Detection of Behavior of Nonlinearities of Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Javad%20Mollakazemi">Mohammad Javad Mollakazemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Farhad%20Asadi"> Farhad Asadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Aref%20Ghafouri"> Aref Ghafouri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we considered and applied parametric modeling for some experimental data of dynamical system.

As a result, this material group has attracted more attention in recent years. Adsorption is one of the common processes for remediation of aromatic compounds. In this study, porous clay hetrostructers (PCHs) are synthesized through gallery template approach and cetyltrimethylammonium bromide and dodecylamine used as template and co-template, respectively. Porous clay is characterized by XRD and FTIR. Batch adsorption experiments were carried out to investigate the effect of various adsorption parameters like adsorbent dosage, pH, initial concentration and contact time. It was found that by increasing adsorbent dosage from 0.5gr/lit to 4gr/lit, toluene removal is increased from 34% to 88.1%. Increasing contact time and decreasing the pH of aqueous solution increases toluene removal efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption" title="adsorption">adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=clay" title=" clay"> clay</a>, <a href="https://publications.waset.org/abstracts/search?q=nano-porous" title=" nano-porous"> nano-porous</a>, <a href="https://publications.waset.org/abstracts/search?q=toluene" title=" toluene"> toluene</a> </p> <a href="https://publications.waset.org/abstracts/18939/adsorption-of-toluene-from-aqueous-solutions-by-porous-clay-hetero-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18939.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">338</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">284</span> Model Order Reduction for Frequency Response and Effect of Order of Method for Matching Condition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aref%20Ghafouri">Aref Ghafouri</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20javad%20Mollakazemi"> Mohammad javad Mollakazemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Farhad%20Asadi"> Farhad Asadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, model order reduction method is used for approximation in linear and nonlinearity aspects in some experimental data.

Many instability problems of cutting slopes were found lying on high slaking mudrocks. It has become one of the major concerns to geotechnical engineer as mudrocks cover up to 50% of sedimentary rocks in the geologic records. Mudrocks display properties between soils and rocks which can be very hard to understand. Therefore, this paper aims to review the definition, mineralogy, geo-chemistry, classification and engineering properties of mudrocks. As water has become one of the major factors that will rapidly change the behaviour of mudrocks, a review on the shear strength of mudrocks in Derbyshire has been made using a fully automated hydraulic stress path testing system under three states: dry, short-term inundated and long-term inundated. It can be seen that the strength of mudrocks has deteriorated as it condition changed from dry to short-term inundated and finally to long-term inundated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mudrocks" title="mudrocks">mudrocks</a>, <a href="https://publications.waset.org/abstracts/search?q=sedimentary%20rocks" title=" sedimentary rocks"> sedimentary rocks</a>, <a href="https://publications.waset.org/abstracts/search?q=inundation" title=" inundation"> inundation</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20strength" title=" shear strength"> shear strength</a> </p> <a href="https://publications.waset.org/abstracts/70946/understanding-mudrocks-and-their-shear-strength-deterioration-associated-with-inundation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70946.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">235</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">280</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.

This development has considered the impact of the PCM density variation between the solid phase and liquid phase. This contribution will increase the assessment accuracy of the electric output of the PV-PCM module. The second contribution is to assess the impact of the expanded composite graphite-PCM on the PV electric output in Milan for a whole year. The novel one-dimensional model has been solved using MATLAB software. The results of this model have been validated against literature experiment work. The weather and the solar radiation data have been collected. The impact of expanded graphite-PCM on the electric output of the PV panel for a whole year has been investigated.

In this spectrum the start point is about 0.02 Mev, the absorption edges are about 0.06 Mev and 0.07 Mev, and average energy is about 0.05 Mev. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=X-spectrum" title="X-spectrum">X-spectrum</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=Monte%20Carlo" title=" Monte Carlo"> Monte Carlo</a>, <a href="https://publications.waset.org/abstracts/search?q=tube" title=" tube"> tube</a> </p> <a href="https://publications.waset.org/abstracts/32738/statistical-study-and-simulation-of-140-kv-x-ray-tube-by-monte-carlo" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32738.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">722</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">274</span> Hydrodynamic Analysis on the Body of a Solar Autonomous Underwater Vehicle by Numerical Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Moonesun">Mohammad Moonesun</a>, <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Asadi%20Asrami"> Ehsan Asadi Asrami</a>, <a href="https://publications.waset.org/abstracts/search?q=Julia%20Bodnarchuk"> Julia Bodnarchuk </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the case of Solar Autonomous Underwater Vehicle, which uses photovoltaic panels to provide its required power, due to limitation of energy, accurate estimation of resistance and energy has major sensitivity. In this work, hydrodynamic calculations by numerical method for a solar autonomous underwater vehicle equipped by two 50 W photovoltaic panels has been studied. To evaluate the required power and energy, hull hydrodynamic resistance in several velocities should be taken into account. To do this assessment, the ANSYS FLUENT 18 applied as Computational Fluid Dynamics (CFD) tool that solves Reynolds Average Navier Stokes (RANS) equations around AUV hull, and K-ω SST is used as turbulence model. To validate of solution method and modeling approach, the model of Myring submarine that it’s experimental data was available, is simulated. There is good agreement between numerical and experimental results. Also, these results showed that the K-ω SST Turbulence model is an ideal method to simulate the AUV motion in low velocities. <p class="card-text"><strong>Keywords:</strong> <a
