The data required for this study is obtained from both accident and inventory database of Iran Railways during 2009-2015. The Ordered Probit model is developed using SPSS software to identify the significant factors in the accident severity at rail-road level crossings. The results show that 'train speed', 'vehicle type' and 'weather' are the most important factors affecting the severity of the accident. The results of these studies assist to allocate resources in the right place. This paper suggests mandating the regulations to reduce train speed at rail-road level crossings in bad weather conditions to improve the safety of rail-road level crossings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rail-road%20level%20crossing" title="rail-road level crossing">rail-road level crossing</a>, <a href="https://publications.waset.org/abstracts/search?q=ordered%20probit%20model" title=" ordered probit model"> ordered probit model</a>, <a href="https://publications.waset.org/abstracts/search?q=accidents%E2%80%99%20severity" title=" accidents’ severity"> accidents’ severity</a>, <a href="https://publications.waset.org/abstracts/search?q=significant%20factors" title=" significant factors"> significant factors</a> </p> <a href="https://publications.waset.org/abstracts/127904/identifying-key-factors-for-accidents-severity-at-rail-road-level-crossings-using-ordered-probit-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127904.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">151</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">239</span> Long-Run Relationship among Tehran Stock Exchange and the GCC Countries Financial Markets, Before and After 2007/2008 Financial Crisis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Hossein%20Ranjbar">Mohammad Hossein Ranjbar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Bagheri"> Mahdi Bagheri</a>, <a href="https://publications.waset.org/abstracts/search?q=B.%20Shivaraj"> B.

Eight markets were included: the stock market of Iran, Kuwait, Bahrain, Qatar, Saudi Arabia, Dubai, Abu Dhabi and Oman. Daily country market indices were collected from January 2005 to December 2010. The potential time-varying behaviors of long-run stock market relationship among selected markets are tested applying correlation test, Augmented Dick Fuller test (ADF), Bilateral and Multilateral Cointegration (Johansen), and the Granger Causality test. The findings suggest that stock market of Iran is negatively correlated with most of the selected markets in the whole duration. But contemporaneous correlations among the eight selected markets are increased positively in period of financial crises. Bilateral Cointegration between selected markets suggests that there is no integration between Tehran stock exchange and other selected markets. Among other markets, except the stock market of Dubai and Abu Dhabi as a one pair, are not cointegrated in whole, but in duration of financial crises integration between selected markets are increased. Finally, investigation of the casual relationship among eight financial markets suggests there are unidirectional and bidirectional causal relationship among some of stock market indices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=financial%20crises" title="financial crises">financial crises</a>, <a href="https://publications.waset.org/abstracts/search?q=Middle%20East" title=" Middle East"> Middle East</a>, <a href="https://publications.waset.org/abstracts/search?q=stock%20market%20integration" title=" stock market integration"> stock market integration</a>, <a href="https://publications.waset.org/abstracts/search?q=Granger%20Causality%20test" title=" Granger Causality test"> Granger Causality test</a>, <a href="https://publications.waset.org/abstracts/search?q=ARDL%20test" title=" ARDL test"> ARDL test</a> </p> <a href="https://publications.waset.org/abstracts/36061/long-run-relationship-among-tehran-stock-exchange-and-the-gcc-countries-financial-markets-before-and-after-20072008-financial-crisis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36061.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">394</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">238</span> Secrecy Analysis in Downlink Cellular Networks in the Presence of D2D Pairs and Hardware Impairment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Rahimi">Mahdi Rahimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Mahdi%20Mojahedian"> Mohammad Mahdi Mojahedian</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Reza%20Aref"> Mohammad Reza Aref</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a cellular communication scenario with a transmitter and an authorized user is considered to analyze its secrecy in the face of eavesdroppers and the interferences propagated unintentionally through the communication network.

In this paper, the use of waterflooding is demonstrated for the petroleum reservoirs of the Kashkari oil field in northern Afghanistan. The technique is based on the Buckley–Leverett frontal-displacement theory, which enables computation of the progress of the waterfront in the reservoir. The relative permeabilities of oil and water, the residual oil saturation, and the irreducible water saturation are obtained from a laboratory experiment. The technique is applied to the laboratory plane-reservoir model to investigate the displacement mechanism and is then compared with the theoretical calculation. Lastly, the technique is applied to the Kashkari oil field to predict the feasible amount of oil that could be produced from this reservoir. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Buckley%E2%80%93Leverett" title="Buckley–Leverett">Buckley–Leverett</a>, <a href="https://publications.waset.org/abstracts/search?q=waterflooding" title=" waterflooding"> waterflooding</a>, <a href="https://publications.waset.org/abstracts/search?q=petroleum%20reservoir%20engineering" title=" petroleum reservoir engineering"> petroleum reservoir engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=two-phase%20flow" title=" two-phase flow"> two-phase flow</a>, <a href="https://publications.waset.org/abstracts/search?q=immiscible%20displacement" title=" immiscible displacement"> immiscible displacement</a>, <a href="https://publications.waset.org/abstracts/search?q=porous%20media" title=" porous media"> porous media</a>, <a href="https://publications.waset.org/abstracts/search?q=relative%20permeability" title=" relative permeability"> relative permeability</a> </p> <a href="https://publications.waset.org/abstracts/111058/application-of-waterflooding-to-the-kashkari-oil-field-in-northern-afghanistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111058.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">203</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">236</span> Measuring Investigation and Computational Simulation of Cavitation Phenomenon Effects on the Industrial Centrifugal Pump Vibration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Hamzehei">Mahdi Hamzehei</a>, <a href="https://publications.waset.org/abstracts/search?q=Homan%20Alimoradzadeh"> Homan Alimoradzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Shahriyari"> Mahdi Shahriyari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, vibration of the industrial centrifugal pumps studied by measuring analysis and computational simulation. Effects of different parameters on pump vibration were investigated. Also, simulation of cavitation in the centrifugal pump was down. First, via CF-TURBO software, the pump impeller and the fluid passing through the pump is modelled and finally, the phenomenon of cavitation in the impeller has been modelled by Ansys software. Also, the effects of changes in the amount of NPSH and bubbles generation in the pump impeller were investigated. By simulation of piping with pipe flow software, effect of fluid velocity and pressure on hydraulics and vibration were studied computationally by applying Computational Fluid Dynamic (CFD) techniques, fluent software and experimentally. Furthermore, this comparison showed that the model can predict hydraulics and vibration behaviour. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cavitation" title="cavitation">cavitation</a>, <a href="https://publications.waset.org/abstracts/search?q=vibration" title=" vibration"> vibration</a>, <a href="https://publications.waset.org/abstracts/search?q=centrifugal%20pumps" title=" centrifugal pumps"> centrifugal pumps</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20curves" title=" performance curves"> performance curves</a>, <a href="https://publications.waset.org/abstracts/search?q=NPSH" title=" NPSH"> NPSH</a> </p> <a href="https://publications.waset.org/abstracts/5866/measuring-investigation-and-computational-simulation-of-cavitation-phenomenon-effects-on-the-industrial-centrifugal-pump-vibration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5866.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">543</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">235</span> Stabilization of a Three-Pole Active Magnetic Bearing by Hybrid Control Method in Static Mode</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Kiani">Mahdi Kiani</a>, <a href="https://publications.waset.org/abstracts/search?q=Hassan%20Salarieh"> Hassan Salarieh</a>, <a href="https://publications.waset.org/abstracts/search?q=Aria%20Alasty"> Aria Alasty</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20Mahdi%20Darbandi"> S.

The system is inherently nonlinear and conventional nonlinear controllers are a little complicated, while the proposed hybrid controller has a piecewise linear form, i.e. linear in each sub-region. A state-feedback hybrid controller is designed in this study, and the unmeasurable states are estimated by an observer. The gains of the hybrid controller are obtained by the Linear Quadratic Regulator (LQR) method in each sub-region. To evaluate the performance, the designed controller is implemented on an experimental setup in static mode. The experimental results show that the proposed method can efficiently stabilize the three-pole AMB system. The simplicity of design, domain of attraction, uncomplicated control law, and computational time are advantages of this method over other nonlinear control strategies in AMB systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=active%20magnetic%20bearing" title="active magnetic bearing">active magnetic bearing</a>, <a href="https://publications.waset.org/abstracts/search?q=three%20pole%20AMB" title=" three pole AMB"> three pole AMB</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20control" title=" hybrid control"> hybrid control</a>, <a href="https://publications.waset.org/abstracts/search?q=Lyapunov%20function" title=" Lyapunov function"> Lyapunov function</a> </p> <a href="https://publications.waset.org/abstracts/53804/stabilization-of-a-three-pole-active-magnetic-bearing-by-hybrid-control-method-in-static-mode" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53804.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">341</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">234</span> Design and Simulation Interface Circuit for Piezoresistive Accelerometers with Offset Cancellation Ability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohsen%20Bagheri">Mohsen Bagheri</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Afifi"> Ahmad Afifi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a new method for read out of the piezoresistive accelerometer sensors.

In order to use these resources, development and functioning optimization of refineries and industrial units is mandatory. Heat exchanger is one of the most important and strategic equipment which its key role in the process of production is clear to everyone. For instance, if the temperature of a processing fluid is not set as needed by heat exchangers, the specifications of desired product can change profoundly. Crude oil enters a network of heat exchangers in atmospheric distillation section before getting into the distillation tower; in this case, well-functioning of heat exchangers can significantly affect the operation of distillation tower. In this paper, different scenarios for pre-heating of oil are studied using oil and gas simulation software, and the results are discussed. As we reviewed various scenarios, adding a heat exchanger to pre-heating network is proposed as the most efficient factor in improving all governing parameters of the tower i.e. temperature, pressure, and reflux rate. This exchanger is embedded in crude oil’s path. Crude oil enters the exchanger after E-101 and exchanges heat with discharging kerosene pump around from E-136.

S. Eliot: A Comparative Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahin%20Pourmorad%20Naseri">Mahin Pourmorad Naseri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Myths have been an inseparable aspect of man’s life in all nations and cultures across the world over time; however, it seems that the form and use of myths in the poetry of the 20th century have gained a new meaning and purpose. Among the poets of the time, T. S. Eliot in English and Mahdi Akhavan Sales in Persian are the two mostly referred to in this regard. In this paper, the pattern of heroic journey as the main theme in the poetry of Akhavan and Eliot will be reviewed, compared, and contrasted. Attempts have been made to find out how the myth of the hero’s journey has been reflected in the century’s well-known poetry and if myth allusions in these poems confirm or reject Campbell’s claim that mythology can be an appropriate psychological cure for man’s loneliness in today’s life. T. S. Eliot (1888-1965), the English poet, essayist, playwright, publisher, and critic, is mostly known for his modernist poetry and the extensive allusions to mythologies and world literary masterpieces. At the same time, Mahdi Akhavan Sales (1929-1990) Iranian poet, one of the pioneers of modern Persian poetry, is also most well-known for his epic poetic style (Khorasani Style) and also his high amount of allusions to myths, especially Zoroastrian mythology, and his myth-making technique. Although their greatly different cultural background may cause the similarities in their poetic style and themes not to attract attention, at first sight, reading the poems closely through the light of the 20th century’s life context and literary movements reveal interesting similarities in the way they understand and apply myth in their poetry. The present paper reviews the theme of the hero’s journey in Akhavan’s Chavooshi and Eliot’s “Journey of the Magi” from the perspective of Campbell’s notion of mono-myth or the pattern of mythic hero’s journey. The poems will be reviewed in search of the steps of the inward journey the heroes make, the goals they pursue, and how successful they are in achieving the goals. The findings of the study reveal that while the difference in the social context of the poets makes the small differences in the stages of the journey, both journeys end in a gloomy atmosphere for the disappointedly isolated hero who is finally left alone in the godless and materialistic world of 20th century. It is also evident that both poets meant to fulfill their responsibility of reviving mythology in writing the poems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=myth" title="myth">myth</a>, <a href="https://publications.waset.org/abstracts/search?q=Akhavan" title=" Akhavan"> Akhavan</a>, <a href="https://publications.waset.org/abstracts/search?q=Eliot" title=" Eliot"> Eliot</a>, <a href="https://publications.waset.org/abstracts/search?q=poetry" title=" poetry"> poetry</a>, <a href="https://publications.waset.org/abstracts/search?q=hero%27s%20journey" title=" hero's journey"> hero's journey</a> </p> <a href="https://publications.waset.org/abstracts/152309/heros-journey-in-the-poetry-of-mahdi-akhavsn-sales-and-t-s-eliot-a-comparative-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152309.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">99</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">229</span> Improvement a Lower Bound of Energy for Some Family of Graphs, Related to Determinant of Adjacency Matrix</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saieed%20%20Akbari">Saieed Akbari</a>, <a href="https://publications.waset.org/abstracts/search?q=Yousef%20Bagheri"> Yousef Bagheri</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20Hossein%20Ghodrati"> Amir Hossein Ghodrati</a>, <a href="https://publications.waset.org/abstracts/search?q=Sima%20Saadat%20Akhtar"> Sima Saadat Akhtar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Let G be a simple graph with the vertex set V (G) and with the adjacency matrix A (G).

Objective: The aim of this study is To estimate the prevalence of cases of Q fever in hospitalized febrile patients in Imam Al Hussain Teaching Medical City in Karbala. Methods: One hundred patients with pyrexia were admitted to the medical ward from 1st August to 31st December 2019. Serological procedures fortified by Enzyme-linked Immunosorbent Assay test. Patients were considered to have acute Q fever when the specific antibodies (IgM and IgG) of phase II of Coxiella burnetii were positive. Results: The mean age of the patients was 35.05±12.93 years; females constituted 60% of them. Eighteen patients (18%) showed positive results for IgM, a lower proportion (13% n=13) had positive IgG levels, and 9% showed equivocal results. Statistical analysis revealed a significant association between positive IgM levels of the female gender and in patients consuming unpasteurized milk. One patient (female aged 60 years) died in the hospital, while all other patients were discharged well. Two female patients were pregnant, and one of them had an abortion. Conclusions: Q fever is more common in febrile patients. The study indicates that this disease should not be overlooked in the differential diagnosis of acute fever. Serological testing should be performed in all patients with acute febrile illness with an unsettling diagnosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibodies" title="antibodies">antibodies</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency" title=" frequency"> frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=immunoglobulin%20IgM" title=" immunoglobulin IgM"> immunoglobulin IgM</a>, <a href="https://publications.waset.org/abstracts/search?q=Q%20fever" title=" Q fever"> Q fever</a> </p> <a href="https://publications.waset.org/abstracts/154564/the-frequency-of-q-fever-among-hospitalized-patients-with-pyrexia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154564.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">123</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">227</span> Investigation of Solvent Effect on Viscosity of Lubricant in Disposable Medical Devices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamed%20Bagheri">Hamed Bagheri</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyd%20Javid%20Shariati"> Seyd Javid Shariati</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The effects of type and amount of solvent on lubricant which is used in disposable medical devices are investigated in this article. Two kinds of common solvent, n-Hexane and n-Heptane, are used. The mechanical behavior of syringe has shown that n-Heptane has better mixing ratio and also more effective spray process in the barrel of syringe than n-Hexane because of similar solubility parameter to silicon oil. The results revealed that movement of plunger in the barrel increases when pure silicone is used because non-uniform film is created on the surface of barrel, and also, it seems that the form of silicon is converted from oil to gel due to sterilization process. The results showed that the convenient mixing ratio of solvent/lubricant oil is 80/20. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=disposal%20medical%20devices" title="disposal medical devices">disposal medical devices</a>, <a href="https://publications.waset.org/abstracts/search?q=lubricant%20oil" title=" lubricant oil"> lubricant oil</a>, <a href="https://publications.waset.org/abstracts/search?q=solvent%20effect" title=" solvent effect"> solvent effect</a>, <a href="https://publications.waset.org/abstracts/search?q=solubility%20parameter" title=" solubility parameter"> solubility parameter</a> </p> <a href="https://publications.waset.org/abstracts/72192/investigation-of-solvent-effect-on-viscosity-of-lubricant-in-disposable-medical-devices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72192.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">231</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">226</span> A Review of Soil Stabilization Techniques</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amin%20Chegenizadeh">Amin Chegenizadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Keramatikerman"> Mahdi Keramatikerman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Soil stabilization is a crucial issue that helps to remove of risks associated with the soil failure.

An extensive finite element analysis was conducted on the through plate CFS bolted connections which are equipped with the slotted hole. The studied parameters in this paper included the following: CFS beam section geometry, the value of slip force, CFS beam thickness. The numerical results indicate that CFS slotted bolted connection exhibit higher inelastic capacity in terms of ductility compare to connection with standards holes. Moreover, the effect of slip force was analysed by comparing the moment-rotation curves of different models with different slip force value. As a result, as the slip force became lower, there was a tendency for the plastic strain to extend from the CFS member to the connection region. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=slip-critical%20bolted%20connection" title="slip-critical bolted connection">slip-critical bolted connection</a>, <a href="https://publications.waset.org/abstracts/search?q=inelastic%20capacity" title=" inelastic capacity"> inelastic capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=slotted%20holes" title=" slotted holes"> slotted holes</a>, <a href="https://publications.waset.org/abstracts/search?q=cold-formed%20steel" title=" cold-formed steel"> cold-formed steel</a>, <a href="https://publications.waset.org/abstracts/search?q=bolt%20slippage" title=" bolt slippage"> bolt slippage</a>, <a href="https://publications.waset.org/abstracts/search?q=slip%20force" title=" slip force"> slip force</a> </p> <a href="https://publications.waset.org/abstracts/59462/improving-inelastic-capacity-of-cold-formed-steel-beams-using-slotted-blotted-connection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59462.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">431</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">222</span> Effect of Oil Contamination on the Liquefaction Behavior of Sandy Soils</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Abolhasan%20Naeini">Seyed Abolhasan Naeini</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Mahdi%20Shojaedin"> Mohammad Mahdi Shojaedin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Oil leakage from the pipelines and the tanks carrying them, or during oil extraction, could lead to the changes in the characteristics and properties of the soil.

Adoption of modern irrigation technology is considered to be a key of increasing the efficiency of water used in agriculture. Policy makers have implemented several ways to induce the adoption of new irrigation technology. The empirical studies show that farmers are reluctant to utilize the use of new irrigation methods. This study aims to assess factors affecting on farmer’s decision on the application of water saving technologies with emphasize on crop price variation and water sources. A Logit model was employed to examine the impact of different variables on use of water saving technology. The required data gathered from a sample of 204 farmers in the year 2012. The results indicate that different variables such as crop price variability, water supply source, high-value crops, farm size, income, education, membership in cooperatives have a positive effect and variables such as age and number of plots have a negative impact on the probability of adopting modern water saving technologies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=irrigation" title="irrigation">irrigation</a>, <a href="https://publications.waset.org/abstracts/search?q=water" title=" water"> water</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20saving%20technology" title=" water saving technology"> water saving technology</a>, <a href="https://publications.waset.org/abstracts/search?q=scarcity" title=" scarcity"> scarcity</a> </p> <a href="https://publications.waset.org/abstracts/88628/crop-price-variation-and-water-saving-technologies-in-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88628.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">225</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">218</span> On Performance of Cache Replacement Schemes in NDN-IoT</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rasool%20Sadeghi">Rasool Sadeghi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sayed%20Mahdi%20Faghih%20Imani"> Sayed Mahdi Faghih Imani</a>, <a href="https://publications.waset.org/abstracts/search?q=Negar%20Najafi"> Negar Najafi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The inherent features of Named Data Networking (NDN) provides a robust solution for Internet of Thing (IoT). Therefore, NDN-IoT has emerged as a combined architecture which exploits the benefits of NDN for interconnecting of the heterogeneous objects in IoT. In NDN-IoT, caching schemes are a key role to improve the network performance. In this paper, we consider the effectiveness of cache replacement schemes in NDN-IoT scenarios. We investigate the impact of replacement schemes on average delay, average hop count, and average interest retransmission when replacement schemes are Least Frequently Used (LFU), Least Recently Used (LRU), First-In-First-Out (FIFO) and Random. The simulation results demonstrate that LFU and LRU present a stable performance when the cache size changes. Moreover, the network performance improves when the number of consumers increases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=NDN-IoT" title="NDN-IoT">NDN-IoT</a>, <a href="https://publications.waset.org/abstracts/search?q=cache%20replacement" title=" cache replacement"> cache replacement</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=ndnSIM" title=" ndnSIM"> ndnSIM</a> </p> <a href="https://publications.waset.org/abstracts/84255/on-performance-of-cache-replacement-schemes-in-ndn-iot" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84255.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">365</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">217</span> Product Line Design with Customization in the Presence of Demand Uncertainty</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Parisa%20Bagheri%20Tookanlou">Parisa Bagheri Tookanlou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we analyze a product line design problem faced by a manufacturing firm where the product line consists of a customized product in addition to a standard product and is offered in a market in which customers are heterogeneous on aesthetic attributes of the product. The customization level of a product is defined by the fraction of aesthetic attributes of the product that the manufacturer chooses to customize. In contrast to the existing literature on product line design that predominantly assumes deterministic demand, we consider the presence of demand uncertainty and frame the product line design problem in a single period (news vendor) setting. We examine the effect of demand uncertainty on product line decisions. Furthermore, we also examine how product line decisions are influenced by channel structure. While we use the centralized channel as a benchmark, we consider the decentralized dual channel where the customized product is sold through an online channel owned by the manufacturer and the standard product is sold through a retailer. We introduce a supply contract between the manufacturer and the retailer for improving channel efficiency and coordinate the distribution channel. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=product%20line%20design" title="product line design">product line design</a>, <a href="https://publications.waset.org/abstracts/search?q=demand%20uncertainty" title=" demand uncertainty"> demand uncertainty</a>, <a href="https://publications.waset.org/abstracts/search?q=customization%20level" title=" customization level"> customization level</a>, <a href="https://publications.waset.org/abstracts/search?q=distribution%20channel" title=" distribution channel"> distribution channel</a> </p> <a href="https://publications.waset.org/abstracts/83258/product-line-design-with-customization-in-the-presence-of-demand-uncertainty" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83258.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">186</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">216</span> Determination of Optimum Fin Wave Angle and Its Effect on the Performance of an Intercooler</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Hamzehei">Mahdi Hamzehei</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyyed%20Amin%20Hakim"> Seyyed Amin Hakim</a>, <a href="https://publications.waset.org/abstracts/search?q=Nahid%20Taherian"> Nahid Taherian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fins play an important role in increasing the efficiency of compact shell and tube heat exchangers by increasing heat transfer.

In this study, the phase equilibria of benzoic acid-supercritical carbon dioxide system were investigated. Regarding the phase equilibria of this system, the modeling of solid-supercritical fluid behavior was performed using the Perturbed-Chain Statistical Association Fluid Theory (PC-SAFT) and Peng-Robinson equations of state (PR EoS). For this purpose, five PC-SAFT EoS parameters for pure benzoic acid were obtained using its experimental vapor pressure. Benzoic acid has association sites and the behavior of the benzoic acid-supercritical fluid system was well-predicted using both equations of state, while the binary interaction parameter values for PR EoS were negative. Genetic algorithm, which is one of the most accurate global optimization algorithms, was also used to optimize the pure benzoic acid parameters and the binary interaction parameters. The AAD% value for the PC-SAFT EoS, were 0.22 for the carbon dioxide-benzoic acid system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=supercritical%20fluids" title="supercritical fluids">supercritical fluids</a>, <a href="https://publications.waset.org/abstracts/search?q=solubility" title=" solubility"> solubility</a>, <a href="https://publications.waset.org/abstracts/search?q=solid" title=" solid"> solid</a>, <a href="https://publications.waset.org/abstracts/search?q=PC-SAFT%20EoS" title=" PC-SAFT EoS"> PC-SAFT EoS</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title=" genetic algorithm"> genetic algorithm</a> </p> <a href="https://publications.waset.org/abstracts/4168/prediction-of-the-solubility-of-benzoic-acid-in-supercritical-co2-using-the-pc-saft-eos" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4168.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">214</span> Physical Parameters Influencing the Yield of Nigella Sativa Oil Extracted by Hydraulic Pressing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hadjadj%20Naima">Hadjadj Naima</a>, <a href="https://publications.waset.org/abstracts/search?q=K.%20Mahdi"> K.

Butt joints usually exist due to the length limits of lumber, leading to concerns about the decrease of structural performance of NLT. This study aimed at investigating the provisions incorporated in Canadian highway bridge design code on the use of but joints in wooden bridge decks. Three and five layers NLT specimens with various configurations were tested under 3-point bending test. It was found that the standard equation is capable of predicting the bending stiffness reduction due to butt joints and 1-m band limit in which, one but joint in every three adjacent lamination is allowed, sounds reasonable. The strength reduction also followed a pattern similar to stiffness reduction. Also reinforcement of the butt joint through nails and steel side plates was attempted. It was found that nail reinforcement recovers the stiffness slightly. In contrast, reinforcing the butt joint through steel side plate improved the flexural performance significantly when compared to the nail reinforcement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nail%20laminated%20timber" title="nail laminated timber">nail laminated timber</a>, <a href="https://publications.waset.org/abstracts/search?q=butt%20joint" title=" butt joint"> butt joint</a>, <a href="https://publications.waset.org/abstracts/search?q=bending%20stiffness" title=" bending stiffness"> bending stiffness</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforcement" title=" reinforcement "> reinforcement </a> </p> <a href="https://publications.waset.org/abstracts/124932/impact-of-butt-joints-on-flexural-properties-of-nail-laminated-timber" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124932.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">185</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">212</span> A Novel Combination Method for Computing the Importance Map of Image</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Absetan">Ahmad Absetan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Nooshyar"> Mahdi Nooshyar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The importance map is an image-based measure and is a core part of the resizing algorithm.

Experiments of different type images demonstrate that our method effectively detects prominent areas can be used in image resizing applications to aware important areas while preserving image quality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=content-aware%20image%20resizing" title="content-aware image resizing">content-aware image resizing</a>, <a href="https://publications.waset.org/abstracts/search?q=visual%20saliency" title=" visual saliency"> visual saliency</a>, <a href="https://publications.waset.org/abstracts/search?q=edge%20density" title=" edge density"> edge density</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20warping" title=" image warping"> image warping</a> </p> <a href="https://publications.waset.org/abstracts/35692/a-novel-combination-method-for-computing-the-importance-map-of-image" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35692.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">582</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">211</span> Capacity Optimization in Cooperative Cognitive Radio Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Pirmoradian">Mahdi Pirmoradian</a>, <a href="https://publications.waset.org/abstracts/search?q=Olayinka%20Adigun"> Olayinka Adigun</a>, <a href="https://publications.waset.org/abstracts/search?q=Christos%20Politis"> Christos Politis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cooperative spectrum sensing is a crucial challenge in cognitive radio networks. Cooperative sensing can increase the reliability of spectrum hole detection, optimize sensing time and reduce delay in cooperative networks. In this paper, an efficient central capacity optimization algorithm is proposed to minimize cooperative sensing time in a homogenous sensor network using OR decision rule subject to the detection and false alarm probabilities constraints. The evaluation results reveal significant improvement in the sensing time and normalized capacity of the cognitive sensors. <p class="card-text"><strong>Keywords:</strong> <a
