The SDN architecture offers a new solution that involves separating the control plane from the data plane, which is usually paired together. Network functions traditionally performed on specific hardware can now be abstracted and virtualized on any device, and a centralized software-based administration approach is based on a central controller, facilitating the development of modern applications and services. These plan standards clear the way for a more adaptable, speedier, and more energetic network beneath computer program control compared with a conventional network. We accept SDN gives modern inquire about openings to security, and it can significantly affect network security research in numerous diverse ways. Subsequently, the SDN architecture engages systems to effectively screen activity and analyze threats to facilitate security approach modification and security benefit insertion. The segregation of the data planes and control and, be that as it may, opens security challenges, such as man-in-the-middle attacks (MIMA), denial of service (DoS) attacks, and immersion attacks. In this paper, we analyze security threats to each layer of SDN - application layer - southbound interfaces/northbound interfaces - controller layer and data layer. From a security point of see, the components that make up the SDN architecture have a few vulnerabilities, which may be abused by aggressors to perform noxious activities and hence influence the network and its administrations. Software-defined network assaults are shockingly a reality these days. In a nutshell, this paper highlights architectural weaknesses and develops attack vectors at each layer, which leads to conclusions about further progress in identifying the consequences of attacks and proposing mitigation strategies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=software-defined%20networking" title="software-defined networking">software-defined networking</a>, <a href="https://publications.waset.org/abstracts/search?q=security" title=" security"> security</a>, <a href="https://publications.waset.org/abstracts/search?q=SDN" title=" SDN"> SDN</a>, <a href="https://publications.waset.org/abstracts/search?q=5G%2FIMT-2020" title=" 5G/IMT-2020"> 5G/IMT-2020</a> </p> <a href="https://publications.waset.org/abstracts/148751/software-defined-networking-a-new-approach-to-fifth-generation-networks-security-issues-and-challenges-ahead" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148751.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">20</span> Wear Characteristics of Al Based Composites Fabricated with Nano Silicon Carbide Particles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Reza%20Koushki%20Ardestani">Mohammad Reza Koushki Ardestani</a>, <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Daneshmand"> Saeed Daneshmand</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Heydari%20Vini"> Mohammad Heydari Vini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present study, AA7075/SiO2 composites have been fabricated via liquid metallurgy process. Using the degassing process, the wet ability of the molten aluminum alloys increased which improved the bonding between aluminum matrix and reinforcement (SiO2) particles. AA7075 alloy and SiO2 particles were taken as the base matrix and reinforcements, respectively. Then, contents of 2.5 and 5 wt. % of SiO2 subdivisions were added into the AA7075 matrix. To improve wettability and distribution, reinforcement particles were pre-heated to a temperature of 550°C for each composite sample. A uniform distribution of SiO2 particles was observed through the matrix alloy in the microstructural study. A hardened EN32 steel disc as the counter face was used to evaluate the wear rate pin-on-disc, a wear testing machine containing. The results showed that the wear rate of the AA/SiO2 composites was lesser than that of the monolithic AA7075 samples.

Among them, lattice structures with graded architectures denoted by functionally graded porous materials (FGPMs) have been developed to optimize the structural response. FGPMs are achieved by tailoring the size and density of the internal pores in one or more directions that lead to the desired mechanical properties and structural responses. Also, FGPMs provide more flexible transition and the possibility of designing and fabricating structural elements with complex and variable properties. In this paper, wave propagation in lattice structures with functionally graded (FG) porosity is investigated in order to examine the ability of shock absorbing effect. The behavior of FG porous beams with different porosity distributions under impact load and the effects of porosity distribution and porosity content on the wave speed are studied. Important conclusions are made, along with a discussion of the future scope of studies on FGPMs structures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=functionally%20graded" title="functionally graded">functionally graded</a>, <a href="https://publications.waset.org/abstracts/search?q=porous%20materials" title=" porous materials"> porous materials</a>, <a href="https://publications.waset.org/abstracts/search?q=wave%20propagation" title=" wave propagation"> wave propagation</a>, <a href="https://publications.waset.org/abstracts/search?q=impact%20load" title=" impact load"> impact load</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element" title=" finite element"> finite element</a> </p> <a href="https://publications.waset.org/abstracts/172932/wave-propagation-in-functionally-graded-lattice-structures-under-impact-loads" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172932.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">91</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> Mechanochemical Synthesis of Al2O3/Mo Nanocomposite Powders from Molybdenum Oxide</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Behrooz%20Ghasemi">Behrooz Ghasemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Bahram%20Sharijian"> Bahram Sharijian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Al2O3/Mo nanocomposite powders were successfully synthesized by mechanical milling through mechanochemical reaction between MoO3 and Al. The structural evolutions of powder particles during mechanical milling were studied by X-ray diffractometry (XRD), energy dispersive X-ray spectroscopy(EDX) and scanning electron microscopy (SEM). Results show that Al2O3-Mo was completely obtained after 5 hr of milling. The crystallite sizes of Al2O3 and Mo after milling for 20 hr were about 45 nm and 23 nm, respectively. With longer milling time, the intensities of Al2O3 and Mo peaks decreased and became broad due to the decrease in crystallite size. Morphological features of powders were influenced by the milling time. The resulting Al2O3- Mo nanocomposite powder exhibited an average particle size of 200 nm after 20 hr of milling. Also nanocomposite powder after 10 hr milling had relatively equiaxed shape with uniformly distributed Mo phase in Al2O3 matrix. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Al2O3%2FMo" title="Al2O3/Mo">Al2O3/Mo</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocomposites" title=" nanocomposites"> nanocomposites</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanochemical" title=" mechanochemical"> mechanochemical</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20milling" title=" mechanical milling"> mechanical milling</a> </p> <a href="https://publications.waset.org/abstracts/11618/mechanochemical-synthesis-of-al2o3mo-nanocomposite-powders-from-molybdenum-oxide" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11618.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">368</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> Evaluation of Dynamic Behavior of a Rotor-Bearing System in Operating Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Hadi%20Jalali">Mohammad Hadi Jalali</a>, <a href="https://publications.waset.org/abstracts/search?q=Behrooz%20Shahriari"> Behrooz Shahriari</a>, <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20Ghayour"> Mostafa Ghayour</a>, <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Ziaei-Rad"> Saeed Ziaei-Rad</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahram%20Yousefi"> Shahram Yousefi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Most flexible rotors can be considered as beam-like structures.

Narrow microchannels are designed to generate an efficient electroosmotic flow near the walls. Microelectrodes are embedded in the lateral sides and actuated by low electric potential to generate pumping effect inside the channel. Based on the simulation study, the fluid velocity increases by increasing the electric potential amplitude. We achieve a net flow velocity of 100 µm/s, by applying +/- 2 V to the electrode structures.

Preventing excessive contamination of water and soil with pesticides and chemical fertilizers is important in order to produce healthy food. For this purpose, two potato cultivars (Sante and Marfona) and seven levels of fertilizer (non-fertilizer, chemical fertilizer, granulated chicken manure, common manure, compost, vermicompost and tea compost) were evaluated by factorial experiment based on randomized complete block design (RCBD) with three replications. According to the results, the effect of different manure was significant on number of tubers per plant, tuber weight per plant and tuber yield. The highest value of these traits was obtained by using of chicken manure which was significantly superior to other treatments. However, there was no significant difference between the two varieties. According to the results, the use of chicken manure has produced the highest potato yield even in comparison with the use of chemical fertilizer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=organic%20farming" title="organic farming">organic farming</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20manure" title=" organic manure"> organic manure</a>, <a href="https://publications.waset.org/abstracts/search?q=potato" title=" potato"> potato</a>, <a href="https://publications.waset.org/abstracts/search?q=tuber%20yield" title=" tuber yield"> tuber yield</a> </p> <a href="https://publications.waset.org/abstracts/95085/effect-of-organic-manure-on-production-of-potato-solanum-tuberosum-l" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95085.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">12</span> Realistic Testing Procedure of Power Swing Blocking Function in Distance Relay</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farzad%20Razavi">Farzad Razavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Behrooz%20Taheri"> Behrooz Taheri</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Parpaei"> Mohammad Parpaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Mohammadi%20Ghalesefidi"> Mehdi Mohammadi Ghalesefidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Siamak%20Zarei"> Siamak Zarei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As one of the major problems in protecting large-dimension power systems, power swing and its effect on distance have caused a lot of damages to energy transfer systems in many parts of the world. Therefore, power swing has gained attentions of many researchers, which has led to invention of different methods for power swing detection. Power swing detection algorithm is highly important in distance relay, but protection relays should have general requirements such as correct fault detection, response rate, and minimization of disturbances in a power system. To ensure meeting the requirements, protection relays need different tests during development, setup, maintenance, configuration, and troubleshooting steps. This paper covers power swing scheme of the modern numerical relay protection, 7sa522 to address the effect of the different fault types on the function of the power swing blocking. In this study, it was shown that the different fault types during power swing cause different time for unblocking distance relay. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=power%20swing" title="power swing">power swing</a>, <a href="https://publications.waset.org/abstracts/search?q=distance%20relay" title=" distance relay"> distance relay</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20system%20protection" title=" power system protection"> power system protection</a>, <a href="https://publications.waset.org/abstracts/search?q=relay%20test" title=" relay test"> relay test</a>, <a href="https://publications.waset.org/abstracts/search?q=transient%20in%20power%20system" title=" transient in power system"> transient in power system</a> </p> <a href="https://publications.waset.org/abstracts/82234/realistic-testing-procedure-of-power-swing-blocking-function-in-distance-relay" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82234.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">384</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">11</span> Investigating the Organizational Capacity of Communities Affecting Water Supply Resilience </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Behrooz%20Balaei">Behrooz Balaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Suzanne%20Wilkinson"> Suzanne Wilkinson</a>, <a href="https://publications.waset.org/abstracts/search?q=Regan%20Potangaroa"> Regan Potangaroa</a>, <a href="https://publications.waset.org/abstracts/search?q=Larry%20Abel"> Larry Abel</a>, <a href="https://publications.waset.org/abstracts/search?q=Philip%20McFarlane"> Philip McFarlane</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water supply system failure has serious direct and indirect effects on people wellbeing. Post-disaster water system serviceability depends on a variety of factors from technical characteristics to social, economic, and organizational attributes of communities. This paper tests the organizational factors affecting water supply resilience to outline how these factors contributed to previous disasters. To do so, a framework is briefly introduced in this study to provide a clear guide to identify the significant relevant organizational factors. Then the factors affecting water serviceability following a disaster are outlines. Next, these factors are measured in the case of Tropical Cyclone Pam, which hit Vanuatu in March 2015. Reviewing the existing literature has also been carried out to obtain a comprehensive understanding of the background A site visit and a series of interviews have also been undertaken following the cyclone to collect site-specific data and information. In the end, the organizational factors were ranked to enable decision makers to identify significance of each factor compared to the others. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=water%20supply" title="water supply">water supply</a>, <a href="https://publications.waset.org/abstracts/search?q=resilience" title=" resilience"> resilience</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20capacity" title=" organizational capacity"> organizational capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=Vanuatu" title=" Vanuatu"> Vanuatu</a>, <a href="https://publications.waset.org/abstracts/search?q=Tropical%20Cyclone%20Pam" title=" Tropical Cyclone Pam"> Tropical Cyclone Pam</a> </p> <a href="https://publications.waset.org/abstracts/109289/investigating-the-organizational-capacity-of-communities-affecting-water-supply-resilience" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109289.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">129</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">10</span> Effects on Cortical Thickness due to Musical Training in Elementary School Children: The Importance of Manual Structural Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saba%20Daneshmand">Saba Daneshmand</a>, <a href="https://publications.waset.org/abstracts/search?q=Assal%20Habibi"> Assal Habibi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Studying musicians has become a prominent approach in macrostructural neuroscience research aimed at exploring the influence of environmental factors on brain development due to the significant impact of musical training on the brain. Although longitudinal studies can establish a direct causal relationship between musical training and brain development, only a limited number of studies have been conducted for a long enough duration. We recruited children for the experimental music group to participate in an after-school music program which was compared to the control group that had no such after-school program or enrichment activities. We ultimately calculated cortical thickness, a distinct measure of development. When a task such as playing an instrument occurs frequently, the associated neural processes become quicker and more refined over time, causing only the necessary pathways to remain; this, therefore, results in cortical thinning. The Brain and Music Lab has identified the anterior and posterior superior temporal gyrus, Heschl's gyrus, and the inferior regions to be involved with musicianship. The past study only found that the posterior superior temporal gyrus experienced a larger thinning in the music group compared to the control; however, we expect our ongoing study to produce similar but more intense results, including thinning in the other regions associated with musicianship. We believe the limited results of the previous study are due to its short duration which is why this ongoing and more lengthy longitudinal study is a significant and indispensable contribution in helping us discover the important developmental aspects of musical training. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cortical%20thickness" title="cortical thickness">cortical thickness</a>, <a href="https://publications.waset.org/abstracts/search?q=music" title=" music"> music</a>, <a href="https://publications.waset.org/abstracts/search?q=neuroimaging" title=" neuroimaging"> neuroimaging</a>, <a href="https://publications.waset.org/abstracts/search?q=child%20development" title=" child development"> child development</a> </p> <a href="https://publications.waset.org/abstracts/192654/effects-on-cortical-thickness-due-to-musical-training-in-elementary-school-children-the-importance-of-manual-structural-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192654.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">16</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">9</span> Evaluation of Osteoprotegrin (OPG) and Tumor Necrosis Factor A (TNF-A) Changes in Synovial Fluid and Serum in Dogs with Osteoarthritis; An Experimental Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Behrooz%20Nikahval">Behrooz Nikahval</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Saeed%20Ahrari-Khafi"> Mohammad Saeed Ahrari-Khafi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sakineh%20Behroozpoor"> Sakineh Behroozpoor</a>, <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Nazifi"> Saeed Nazifi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Osteoarthritis (OA) is a progressive and degenerative condition of the articular cartilage and other joints’ structures. It is essential to diagnose this condition as early as possible. The present research was performed to measure the Osteoprotegrin (OPG) and Tumor Necrosis Factor α (TNF-α) in synovial fluid and blood serum of dogs with surgically transected cruciate ligament as a model of OA, to evaluate if measuring of these parameters can be used as a way of early diagnosis of OA. In the present study, four mature, clinically healthy dogs were selected to investigate the effect of experimental OA, on OPG and TNF-α as a way of early detection of OA. OPG and TNF-α were measured in synovial fluid and blood serum on days 0, 14, 28, 90 and 180 after surgical transaction of cranial cruciate ligament in one stifle joint. Statistical analysis of the results showed that there was a significant increase in TNF-α in both synovial fluid and blood serum. OPG showed a decrease two weeks after OA induction. However, it fluctuated afterward. In conclusion, TNF-α could be used in both synovial fluid and blood serum as a way of early detection of OA; however, further research still needs to be conducted on OPG values in OA detection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=osteoarthritis" title="osteoarthritis">osteoarthritis</a>, <a href="https://publications.waset.org/abstracts/search?q=osteoprotegrin" title=" osteoprotegrin"> osteoprotegrin</a>, <a href="https://publications.waset.org/abstracts/search?q=tumor%20necrosis%20factor%20%CE%B1" title=" tumor necrosis factor α"> tumor necrosis factor α</a>, <a href="https://publications.waset.org/abstracts/search?q=synovial%20fluid" title=" synovial fluid"> synovial fluid</a>, <a href="https://publications.waset.org/abstracts/search?q=serum" title=" serum"> serum</a>, <a href="https://publications.waset.org/abstracts/search?q=dog" title=" dog"> dog</a> </p> <a href="https://publications.waset.org/abstracts/61004/evaluation-of-osteoprotegrin-opg-and-tumor-necrosis-factor-a-tnf-a-changes-in-synovial-fluid-and-serum-in-dogs-with-osteoarthritis-an-experimental-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61004.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">318</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">8</span> Introduction of Robust Multivariate Process Capability Indices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Behrooz%20Khalilloo">Behrooz Khalilloo</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Shahriari"> Hamid Shahriari</a>, <a href="https://publications.waset.org/abstracts/search?q=Emad%20Roghanian"> Emad Roghanian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Process capability indices (PCIs) are important concepts of statistical quality control and measure the capability of processes and how much processes are meeting certain specifications. An important issue in statistical quality control is parameter estimation. Under the assumption of multivariate normality, the distribution parameters, mean vector and variance-covariance matrix must be estimated, when they are unknown. Classic estimation methods like method of moment estimation (MME) or maximum likelihood estimation (MLE) makes good estimation of the population parameters when data are not contaminated. But when outliers exist in the data, MME and MLE make weak estimators of the population parameters. So we need some estimators which have good estimation in the presence of outliers. In this work robust M-estimators for estimating these parameters are used and based on robust parameter estimators, robust process capability indices are introduced. The performances of these robust estimators in the presence of outliers and their effects on process capability indices are evaluated by real and simulated multivariate data. The results indicate that the proposed robust capability indices perform much better than the existing process capability indices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multivariate%20process%20capability%20indices" title="multivariate process capability indices">multivariate process capability indices</a>, <a href="https://publications.waset.org/abstracts/search?q=robust%20M-estimator" title=" robust M-estimator"> robust M-estimator</a>, <a href="https://publications.waset.org/abstracts/search?q=outlier" title=" outlier"> outlier</a>, <a href="https://publications.waset.org/abstracts/search?q=multivariate%20quality%20control" title=" multivariate quality control"> multivariate quality control</a>, <a href="https://publications.waset.org/abstracts/search?q=statistical%20quality%20control" title=" statistical quality control"> statistical quality control</a> </p> <a href="https://publications.waset.org/abstracts/81586/introduction-of-robust-multivariate-process-capability-indices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81586.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">283</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">7</span> Combined Safety and Cybersecurity Risk Assessment for Intelligent Distributed Grids</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anders%20Thors%C3%A9n">Anders Thorsén</a>, <a href="https://publications.waset.org/abstracts/search?q=Behrooz%20Sangchoolie"> Behrooz Sangchoolie</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Folkesson"> Peter Folkesson</a>, <a href="https://publications.waset.org/abstracts/search?q=Ted%20Strandberg"> Ted Strandberg</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As more parts of the power grid become connected to the internet, the risk of cyberattacks increases. To identify the cybersecurity threats and subsequently reduce vulnerabilities, the common practice is to carry out a cybersecurity risk assessment. For safety classified systems and products, there is also a need for safety risk assessments in addition to the cybersecurity risk assessment in order to identify and reduce safety risks. These two risk assessments are usually done separately, but since cybersecurity and functional safety are often related, a more comprehensive method covering both aspects is needed. Some work addressing this has been done for specific domains like the automotive domain, but more general methods suitable for, e.g., intelligent distributed grids, are still missing. One such method from the automotive domain is the Security-Aware Hazard Analysis and Risk Assessment (SAHARA) method that combines safety and cybersecurity risk assessments. This paper presents an approach where the SAHARA method has been modified in order to be more suitable for larger distributed systems. The adapted SAHARA method has a more general risk assessment approach than the original SAHARA. The proposed method has been successfully applied on two use cases of an intelligent distributed grid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=intelligent%20distribution%20grids" title="intelligent distribution grids">intelligent distribution grids</a>, <a href="https://publications.waset.org/abstracts/search?q=threat%20analysis" title=" threat analysis"> threat analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20assessment" title=" risk assessment"> risk assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=safety" title=" safety"> safety</a>, <a href="https://publications.waset.org/abstracts/search?q=cybersecurity" title=" cybersecurity"> cybersecurity</a> </p> <a href="https://publications.waset.org/abstracts/143611/combined-safety-and-cybersecurity-risk-assessment-for-intelligent-distributed-grids" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143611.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">153</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">6</span> Mechanical Investigation Approach to Optimize the High-Velocity Oxygen Fuel Fe-Based Amorphous Coatings Reinforced by B4C Nanoparticles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Behrooz%20Movahedi">Behrooz Movahedi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fe-based amorphous feedstock powders are used as the matrix into which various ratios of hard B4C nanoparticles (0, 5, 10, 15, 20 vol.%) as reinforcing agents were prepared using a planetary high-energy mechanical milling. The ball-milled nanocomposite feedstock powders were also sprayed by means of high-velocity oxygen fuel (HVOF) technique. The characteristics of the powder particles and the prepared coating depending on their microstructures and nanohardness were examined in detail using nanoindentation tester. The results showed that the formation of the Fe-based amorphous phase was noticed over the course of high-energy ball milling. It is interesting to note that the nanocomposite coating is divided into two regions, namely, a full amorphous phase region and homogeneous dispersion of B4C nanoparticles with a scale of 10–50 nm in a residual amorphous matrix. As the B4C content increases, the nanohardness of the composite coatings increases, but the fracture toughness begins to decrease at the B4C content higher than 20 vol.%. The optimal mechanical properties are obtained with 15 vol.% B4C due to the suitable content and uniform distribution of nanoparticles. Consequently, the changes in mechanical properties of the coatings were attributed to the changes in the brittle to ductile transition by adding B4C nanoparticles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fe-based%20amorphous" title="Fe-based amorphous">Fe-based amorphous</a>, <a href="https://publications.waset.org/abstracts/search?q=B%E2%82%84C%20nanoparticles" title=" B₄C nanoparticles"> B₄C nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocomposite%20coating" title=" nanocomposite coating"> nanocomposite coating</a>, <a href="https://publications.waset.org/abstracts/search?q=HVOF" title=" HVOF"> HVOF</a> </p> <a href="https://publications.waset.org/abstracts/96966/mechanical-investigation-approach-to-optimize-the-high-velocity-oxygen-fuel-fe-based-amorphous-coatings-reinforced-by-b4c-nanoparticles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96966.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">135</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">5</span> Optimum Locations for Intercity Bus Terminals with the AHP Approach: Case Study of the City of Esfahan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehrdad%20Arabi">Mehrdad Arabi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Beheshtitabar"> Ehsan Beheshtitabar</a>, <a href="https://publications.waset.org/abstracts/search?q=Bahador%20Ghadirifaraz"> Bahador Ghadirifaraz</a>, <a href="https://publications.waset.org/abstracts/search?q=Behrooz%20Forjanizadeh"> Behrooz Forjanizadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Interaction between human, location and activity defines space. In the framework of these relations, space is a container for current specifications in relations of the 3 mentioned elements. The change of land utility considered with average performance range, urban regulations, society requirements etc. will provide welfare and comfort for citizens. From an engineering view it is fundamental that choosing a proper location for a specific civil activity requires evaluation of locations from different perspectives. The debate of desirable establishment of municipal service elements in urban regions is one of the most important issues related to urban planning. In this paper, the research type is applicable based on goal, and is descriptive and analytical based on nature. Initially existing terminals in Esfahan are surveyed and then new locations are presented based on evaluated criteria. In order to evaluate terminals based on the considered factors, an AHP model is used at first to estimate weight of different factors and then existing and suggested locations are evaluated using Arc GIS software and AHP model results. The results show that existing bus terminals are located in fairly proper locations. Further results of this study suggest new locations to establish terminals based on urban criteria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arc%20GIS" title="Arc GIS">Arc GIS</a>, <a href="https://publications.waset.org/abstracts/search?q=Esfahan%20city" title=" Esfahan city"> Esfahan city</a>, <a href="https://publications.waset.org/abstracts/search?q=optimum%20locations" title=" optimum locations"> optimum locations</a>, <a href="https://publications.waset.org/abstracts/search?q=terminals" title=" terminals"> terminals</a> </p> <a href="https://publications.waset.org/abstracts/24760/optimum-locations-for-intercity-bus-terminals-with-the-ahp-approach-case-study-of-the-city-of-esfahan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24760.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">290</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">4</span> Pultrusion of Side by Side Glass/Polypropylene Fibers: Study of Flexural and Shear Properties </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Behrooz%20Ataee">Behrooz Ataee</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Golzar"> Mohammad Golzar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main purpose of using side by side (SBS) hybrid yarn in pultrusion thermoplastic method is reprisal the effect of high viscosity in melted thermoplastic and reduction of distance between reinforced fiber and melted thermoplastic. SBS hybrid fiber yarn composed of thermoplastic fibers and fiber reinforcement should be produced in the preparation of pultruded thermoplastic composites prepreg to reach better impregnation. An experimental set-up was designed and built to pultrude continues polypropylene and glass fiber to get obtain a suitable impregnated round prepregs. In final stage, the round prepregs come together to produce rectangular profile. Higher fiber volume fraction produces higher void volume fraction, however the second stage of the production process of rectangular profile and the cold die decrease 50% of the void volume fraction. Results show that whit increasing void volume fraction, flexural and shear strength decrease. Also, under certain conditions of parameters the pultruded profiles exhibit better flexural and shear strength. The pulling speed seems to have the greatest influence on the profile quality. In addition, adding cold die strongly increases the surface quality of rectangular profile. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermoplastic%20pultrusion" title="thermoplastic pultrusion">thermoplastic pultrusion</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20pultrusion" title=" hybrid pultrusion"> hybrid pultrusion</a>, <a href="https://publications.waset.org/abstracts/search?q=side-by-side%20fibers" title=" side-by-side fibers"> side-by-side fibers</a>, <a href="https://publications.waset.org/abstracts/search?q=impregnation" title=" impregnation"> impregnation</a> </p> <a href="https://publications.waset.org/abstracts/57363/pultrusion-of-side-by-side-glasspolypropylene-fibers-study-of-flexural-and-shear-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57363.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">258</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">3</span> Modeling Operating Theater Scheduling and Configuration: An Integrated Model in Health-Care Logistics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sina%20Keyhanian">Sina Keyhanian</a>, <a href="https://publications.waset.org/abstracts/search?q=Abbas%20Ahmadi"> Abbas Ahmadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Behrooz%20Karimi"> Behrooz Karimi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We present a multi-objective binary programming model which considers surgical cases are scheduling among operating rooms and the configuration of surgical instruments in limited capacity hospital trays, simultaneously. Many mathematical models have been developed previously in the literature addressing different challenges in health-care logistics such as assigning operating rooms, leveling beds, etc. But what happens inside the operating rooms along with the inventory management of required instruments for various operations, and also their integration with surgical scheduling have been poorly discussed. Our model considers the minimization of movements between trays during a surgery which recalls the famous cell formation problem in group technology. This assumption can also provide a major potential contribution to robotic surgeries. The tray configuration problem which consumes surgical instruments requirement plan (SIRP) and sequence of surgical procedures based on required instruments (SIRO) is nested inside the bin packing problem. This modeling approach helps us understand that most of the same-output solutions will not be necessarily identical when it comes to the rearrangement of surgeries among rooms. A numerical example has been dealt with via a proposed nested simulated annealing (SA) optimization approach which provides insights about how various configurations inside a solution can alter the optimal condition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=health-care%20logistics" title="health-care logistics">health-care logistics</a>, <a href="https://publications.waset.org/abstracts/search?q=hospital%20tray%20configuration" title=" hospital tray configuration"> hospital tray configuration</a>, <a href="https://publications.waset.org/abstracts/search?q=off-line%20bin%20packing" title=" off-line bin packing"> off-line bin packing</a>, <a href="https://publications.waset.org/abstracts/search?q=simulated%20annealing%20optimization" title=" simulated annealing optimization"> simulated annealing optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=surgical%20case%20scheduling" title=" surgical case scheduling"> surgical case scheduling</a> </p> <a href="https://publications.waset.org/abstracts/52021/modeling-operating-theater-scheduling-and-configuration-an-integrated-model-in-health-care-logistics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52021.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">282</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">2</span> Development of Positron Emission Tomography (PET) Tracers for the in-Vivo Imaging of α-Synuclein Aggregates in α-Synucleinopathies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bright%20Chukwunwike%20Uzuegbunam">Bright Chukwunwike Uzuegbunam</a>, <a href="https://publications.waset.org/abstracts/search?q=Wojciech%20%20Paslawski"> Wojciech Paslawski</a>, <a href="https://publications.waset.org/abstracts/search?q=Hans%20Agren"> Hans Agren</a>, <a href="https://publications.waset.org/abstracts/search?q=Christer%20Halldin"> Christer Halldin</a>, <a href="https://publications.waset.org/abstracts/search?q=Wolfgang%20Weber"> Wolfgang Weber</a>, <a href="https://publications.waset.org/abstracts/search?q=Markus%20Luster"> Markus Luster</a>, <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Arzberger"> Thomas Arzberger</a>, <a href="https://publications.waset.org/abstracts/search?q=Behrooz%20Hooshyar%20Yousefi"> Behrooz Hooshyar Yousefi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There is a need to develop a PET tracer that will enable to diagnosis and track the progression of Alpha-synucleinopathies (Parkinson’s disease [PD], dementia with Lewy bodies [DLB], multiple system atrophy [MSA]) in living subjects over time. Alpha-synuclein aggregates (a-syn), which are present in all the stages of disease progression, for instance, in PD, are a suitable target for in vivo PET imaging. For this reason, we have developed some promising a-syn tracers based on a disarylbisthiazole (DABTA) scaffold. The precursors are synthesized via a modified Hantzsch thiazole synthesis. The precursors were then radiolabeled via one- or two-step radiofluorination methods. The ligands were initially screened using a combination of molecular dynamics and quantum/molecular mechanics approaches in order to calculate the binding affinity to a-syn (in silico binding experiments). Experimental in vitro binding assays were also performed. The ligands were further screened in other experiments such as log D, in vitro plasma protein binding & plasma stability, biodistribution & brain metabolite analyses in healthy mice. Radiochemical yields were up to 30% - 72% in some cases. Molecular docking revealed possible binding sites in a-syn and also the free energy of binding to those sites (-28.9 - -66.9 kcal/mol), which correlated to the high binding affinity of the DABTAs to a-syn (Ki as low as 0.5 nM) and selectivity (> 100-fold) over Aβ and tau, which usually co-exist with a-synin some pathologies. The log D values range from 2.88 - 2.34, which correlated with free-protein fraction of 0.28% - 0.5%. Biodistribution experiments revealed that the tracers are taken up (5.6 %ID/g - 7.3 %ID/g) in the brain at 5 min (post-injection) p.i., and cleared out (values as low as 0.39 %ID/g were obtained at 120 min p.i. Analyses of the mice brain 20 min p.i. Revealed almost no radiometabolites in the brain in most cases. It can be concluded that in silico study presents a new venue for the rational development of radioligands with suitable features. The results obtained so far are promising and encourage us to further validate the DABTAs in autoradiography, immunohistochemistry, and in vivo imaging in non-human primates and humans. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alpha-synuclein%20aggregates" title="alpha-synuclein aggregates">alpha-synuclein aggregates</a>, <a href="https://publications.waset.org/abstracts/search?q=alpha-synucleinopathies" title=" alpha-synucleinopathies"> alpha-synucleinopathies</a>, <a href="https://publications.waset.org/abstracts/search?q=PET%20imaging" title=" PET imaging"> PET imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=tracer%20development" title=" tracer development"> tracer development</a> </p> <a href="https://publications.waset.org/abstracts/138870/development-of-positron-emission-tomography-pet-tracers-for-the-in-vivo-imaging-of-a-synuclein-aggregates-in-a-synucleinopathies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138870.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">1</span> Integrated Watershed Management Practice in Chelchai Hyrcanian Forests in the North of Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mashad%20Maramaei">Mashad Maramaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Behrooz%20Chogan"> Behrooz Chogan</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Ahmadi"> Reza Ahmadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Human health and the health of his watershed are inseparable. This is because a watershed is an interconnected system of "land", "water", "air" and "life". Nowadays, most of the world's watersheds show symptoms of unhealthiness and require a prompt solution. It is believed that suitable solution is a participatory and Integrated Watershed Management (IWM). In recent decades the Hyrcanian forests in the north of Iran, which belongs to the end of the third geological era, are suffering from many environmental challenges such as land degradation, increasing trends of flood, drought and accelerated soil erosion. These challenges in the main forested area of the country impose many tangible and intangible damages and human losses. This is despite the fact that in the past decades, forestry programs, watershed management and other activities in the region have been implemented in a parallel and uncoordinated manner. Therefore, recently; the Natural Resources and Watershed Management Organization has resorted to the concept of IWM planning the Hyrcanian watersheds. The Chelchai watershed as mostly degraded watershed in the eastern part of the Hyrcanian forests has been selected as a pilot watershed for implementation of the IWM. It has a drainage area of 25680 hectares and receives an average annual precipitation of 650 mm. In this mountainous region, the average temperature is 17.3 degrees Celsius. About 34% of the watershed is under cultivation, 64% under forest cover, 2% under built up areas and etc. In this research, the effectiveness or ineffectiveness of the IWM model implementation of the Natural Resources and Watershed Management Organization has been evaluated based on questionnaire method and field studies. The results indicated that IWM activities in the study area should be reconsidered and revived. Based on this research and the lessons learned during five years' experience in the Chelchai watershed; authors believe that seven important tasks are necessary for socially acceptable and successful implementation of IWM projects. These are: 1) Establishment of Local Coordination Committee (LCC) at the watershed level 2) working for development of a IWM law among government organizations to organize watershed management and eliminate parallel and contradictory activities 3) More investment on education of local communities, especially women and children 4) Development of trust builder and pattern projects that showing best agricultural and livestock management activities at each of 26 villages 5) Assigning forest protection to local communities. 6) Capacity building of government stakeholders. 7) Helping in the marketing of watershed products. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=integrated%20watershed%20management" title="integrated
