The amorphous and crystalline silica was obtained by the precipitation method from carbonisation process of the rice husk at a temperature of 600 °C and 1000 °C for 7 hours respectively. The epoxy resin was mixed with 5%, 10% and 15% concentrations of amorphous and crystalline silica. The mixture was stirred for 10 minutes and cured at 28 °C for 72 hours and oven dried at 80 °C for 72 hours. The scanning electron microscope image showed the silica sized of 10-30nm was obtained. The water absorption and thickness swelling of epoxy/amorphous silica composite was not significantly different with silica concentration ranged from 0.08% to 0.09% and 0.17% to 0.20% respectively. The maximum modulus of rupture (85 MPa) and modulus of elasticity (3284 MPa) were achieved for 10% silica concentration. For epoxy/crystalline silica composite; the water absorption and thickness swelling were also not significantly different with silica concentration, ranged from 0.08% to 0.11% and 0.16% to 0.18% respectively. The maximum modulus of rupture (47.9 MPa) and modulus of elasticity (2760 MPa) were achieved for 10% silica concentration. Overall, the water absorption and thickness swelling were almost identical for epoxy composite made from either amorphous or crystalline silica. The epoxy composite made from amorphous silica was stronger than crystalline silica. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=epoxy" title="epoxy">epoxy</a>, <a href="https://publications.waset.org/abstracts/search?q=composite" title=" composite"> composite</a>, <a href="https://publications.waset.org/abstracts/search?q=dimensional%20stability" title=" dimensional stability"> dimensional stability</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20bending" title=" static bending"> static bending</a>, <a href="https://publications.waset.org/abstracts/search?q=silica" title=" silica"> silica</a> </p> <a href="https://publications.waset.org/abstracts/84173/properties-of-epoxy-composite-reinforced-with-amorphous-and-crystalline-silica-from-rice-husk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84173.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">215</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">302</span> Analysis of Hydraulic Velocity in Fishway Using CCHE2D Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Abbas%20Kamanbedast">Amir Abbas Kamanbedast</a>, <a href="https://publications.waset.org/abstracts/search?q=Masood%20Mohammad%20Shafipor"> Masood Mohammad Shafipor</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20Ghotboddin"> Amir Ghotboddin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fish way is a structure that in generally using to migrate to the place where they are spawned and is made near the spillway. Preventing fish spawning or migrating to their original place by fishway structures can affect their lives in the river or even erase one access to intended environment. The main objective of these structures is establishing a safe path for fish migration. In the present study first the hydraulic specifications of Hamidieh diversion dam were assessed and then it is problems were evaluated. In this study the dimensions of the fish way, including velocity of pools, were evaluated by CCHE2D software. Then by change slope in this structure streamlines like velocity in the pools were measured. For calibration can be use measuring local velocities in some pools. The information can be seen the fishway width of 0.3 m has minimum rate of descent in the total number of structures (pools and overflow). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fishway" title="fishway">fishway</a>, <a href="https://publications.waset.org/abstracts/search?q=velocity" title=" velocity"> velocity</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamidieh-Diversion%20Dam" title=" Hamidieh-Diversion Dam"> Hamidieh-Diversion Dam</a>, <a href="https://publications.waset.org/abstracts/search?q=CCHE2D%20model" title=" CCHE2D model"> CCHE2D model</a> </p> <a href="https://publications.waset.org/abstracts/26983/analysis-of-hydraulic-velocity-in-fishway-using-cche2d-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26983.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">495</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">301</span> Comparative Analysis of Traditional and Modern Roundabouts Using Sidra Intersection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Mohammad%20Parvini">Amir Mohammad Parvini</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20Masoud%20Rahimi"> Amir Masoud Rahimi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Currently, most parts of the world have shifted from traditional roundabouts to modern roundabouts with respect to the role of roundabouts in reducing accidents, increasing safety, lowering the maintenance costs compared to traffic circles with their improper functional and safety experiences.

The modern roundabout was designed by changes in the traditional one, considering the geometric standards listed in regulations. Then, the modern roundabout was analyzed by applying a heterogeneous traffic by a micro-simulation software SIDRA (5.1). The function, capacity, and safety of the roundabout were analyzed assuming the superiority of modern roundabouts and acceptable LOS.

The paper focuses on the production of independent political documentary by two Malaysian filmmakers, Amir Muhammad and Fahmi Reza. Revolutionary cinema can be understood by utilizing the Third Cinema Theory in order to analyse the meaning and its impact on the audience. The issue surrounding the political cinema in Malaysia is the question of national identity. The implementation of racial or ethnic based politics has resulted in hostility within Malaysia’s multiracial society. Amir Muhammad and Fahmi Reza revisit the Malaysian political history through their films in order to understand the reasons behind the hostility and conflict. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Political%20cinema" title="Political cinema">Political cinema</a>, <a href="https://publications.waset.org/abstracts/search?q=third%20cinema%20theory" title=" third cinema theory"> third cinema theory</a>, <a href="https://publications.waset.org/abstracts/search?q=revolutionary%20cinema" title=" revolutionary cinema"> revolutionary cinema</a>, <a href="https://publications.waset.org/abstracts/search?q=national%20identity" title=" national identity"> national identity</a>, <a href="https://publications.waset.org/abstracts/search?q=racial%20or%20ethnic%20politics" title=" racial or ethnic politics"> racial or ethnic politics</a> </p> <a href="https://publications.waset.org/abstracts/2388/political-cinema-rewriting-the-malaysian-political-history-through-documentary-films" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2388.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">433</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">299</span> Iron Recovery from Red Mud as Zero-Valent Iron Metal Powder Using Direct Electrochemical Reduction Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Franky%20Michael%20Hamonangan%20Siagian">Franky Michael Hamonangan Siagian</a>, <a href="https://publications.waset.org/abstracts/search?q=Affan%20Maulana"> Affan Maulana</a>, <a href="https://publications.waset.org/abstracts/search?q=Himawan%20Tri%20Bayu%20Murti%20Petrus"> Himawan Tri Bayu Murti Petrus</a>, <a href="https://publications.waset.org/abstracts/search?q=Widi%20Astuti"> Widi Astuti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the feasibility of the direct electrowinning method was used to produce zero-valent iron from red mud.

The procedure consists of three states of machine condition namely shortened brush, high impedance relay and maintaining a healthy condition in the alternator. The fault detection algorithm uses Wigner-Ville distribution as a feature extractor and also appropriate feature classifier. In this work, ANN (Artificial Neural Network) and also SVM (support vector machine) were compared to determine more suitable performance evaluated by the mean squared of errors criteria. Modules work together to detect possible faulty conditions of machines working. To test the method performance, a signal database is prepared by making different conditions on a laboratory setup. Therefore, it seems by implementing this method, satisfactory results are achieved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alternator" title="alternator">alternator</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20neural%20network" title=" artificial neural network"> artificial neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=support%20vector%20machine" title=" support vector machine"> support vector machine</a>, <a href="https://publications.waset.org/abstracts/search?q=time-frequency%20analysis" title=" time-frequency analysis"> time-frequency analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Wigner-Ville%20distribution" title=" Wigner-Ville distribution"> Wigner-Ville distribution</a> </p> <a href="https://publications.waset.org/abstracts/60556/alternator-fault-detection-using-wigner-ville-distribution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60556.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">374</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">296</span> A Customize Battery Management Approach for Satellite</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Affan">Muhammad Affan</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Ilyas%20Raza"> Muhammad Ilyas Raza</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Harris%20Hashmi"> Muhammad Harris Hashmi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work is attributed to the battery management unit design of student Satellites under Pakistan National Student Satellite Program (PNSSP). The aim has been to design a customized, low-cost, efficient, reliable and less-complex battery management scheme for the Satellite. Nowadays, Lithium Ion (Li-ion) batteries have become the de-facto standard for remote applications, especially for satellites. Li-ion cells are selected for secondary storage. The design also addresses Li-ion safety requirements by monitoring, balancing and protecting cells for safe and prolonged operation. Accurate voltage measurement of individual cells was the main challenge because all the actions triggered were based on the digital voltage measurement. For this purpose, a resistive-divider network is used to maintain simplicity and cost-effectiveness. To cater the problem of insufficient i/o pins on microcontroller, fast multiplexers and de-multiplexers were used. The discrepancy inherited in the given design is the dissipation of heat due to the dissipative resistors. However, it is still considered to be the optimum adoption, considering the simple and cost-effective nature of the passive balancing technique. Furthermore, it is a completely unique solution, customized to meet specific requirements. However, there is still an option for a more advanced and expensive design. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=satellite" title="satellite">satellite</a>, <a href="https://publications.waset.org/abstracts/search?q=battery%20module" title=" battery module"> battery module</a>, <a href="https://publications.waset.org/abstracts/search?q=passive%20balancing" title=" passive balancing"> passive balancing</a>, <a href="https://publications.waset.org/abstracts/search?q=dissipative" title=" dissipative"> dissipative</a> </p> <a href="https://publications.waset.org/abstracts/157071/a-customize-battery-management-approach-for-satellite" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157071.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">139</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">295</span> CT Medical Images Denoising Based on New Wavelet Thresholding Compared with Curvelet and Contourlet</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Moslemi">Amir Moslemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20movafeghi"> Amir movafeghi</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahab%20Moradi"> Shahab Moradi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the most important challenging factors in medical images is nominated as noise.Image denoising refers to the improvement of a digital medical image that has been infected by Additive White Gaussian Noise (AWGN). The digital medical image or video can be affected by different types of noises. They are impulse noise, Poisson noise and AWGN. Computed tomography (CT) images are subjected to low quality due to the noise. The quality of CT images is dependent on the absorbed dose to patients directly in such a way that increase in absorbed radiation, consequently absorbed dose to patients (ADP), enhances the CT images quality. In this manner, noise reduction techniques on the purpose of images quality enhancement exposing no excess radiation to patients is one the challenging problems for CT images processing. In this work, noise reduction in CT images was performed using two different directional 2 dimensional (2D) transformations; i.e., Curvelet and Contourlet and Discrete wavelet transform(DWT) thresholding methods of BayesShrink and AdaptShrink, compared to each other and we proposed a new threshold in wavelet domain for not only noise reduction but also edge retaining, consequently the proposed method retains the modified coefficients significantly that result in good visual quality. Data evaluations were accomplished by using two criterions; namely, peak signal to noise ratio (PSNR) and Structure similarity (Ssim). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computed%20tomography%20%28CT%29" title="computed tomography (CT)">computed tomography (CT)</a>, <a href="https://publications.waset.org/abstracts/search?q=noise%20reduction" title=" noise reduction"> noise reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=curve-let" title=" curve-let"> curve-let</a>, <a href="https://publications.waset.org/abstracts/search?q=contour-let" title=" contour-let"> contour-let</a>, <a href="https://publications.waset.org/abstracts/search?q=signal%20to%20noise%20peak-peak%20ratio%20%28PSNR%29" title=" signal to noise peak-peak ratio (PSNR)"> signal to noise peak-peak ratio (PSNR)</a>, <a href="https://publications.waset.org/abstracts/search?q=structure%20similarity%20%28Ssim%29" title=" structure similarity (Ssim)"> structure similarity (Ssim)</a>, <a href="https://publications.waset.org/abstracts/search?q=absorbed%20dose%20to%20patient%20%28ADP%29" title=" absorbed dose to patient (ADP)"> absorbed dose to patient (ADP)</a> </p> <a href="https://publications.waset.org/abstracts/37368/ct-medical-images-denoising-based-on-new-wavelet-thresholding-compared-with-curvelet-and-contourlet" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37368.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">441</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">294</span> Study on the Stages of Knowledge Flow in Central Libraries of Tehran Universities by the Pattern of American Productivity & Quality Center</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Reza%20Asnafi">Amir Reza Asnafi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Tajabadi"> Ehsan Tajabadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohsen%20Hajizeinolabedini"> Mohsen Hajizeinolabedini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study is to identify the concept of knowledge flow in central libraries of Tehran universities in by the pattern of American Productivity & Quality Center (APQC). The present study is an applied and descriptive survey in terms of its purpose and the methodology used. In this study, APQC framework was used for data collection. The study population is managers and supervisors of central libraries’ departments of public universities of Tehran belonging to the Ministry of Science, Research and Technology. These libraries include: Central Libraries of Al-Zahra University, Amir Kabir, Tarbiat Modarres, Tehran, Khajeh Nasir Toosi University of Technology, Shahed, Sharif, Shahid Beheshti, Allameh Tabataba'i University, Iran University of Science and Technology. Due to the limited number of members of the community, sampling was not performed and the census was conducted instead. The study of knowledge flow in central libraries of public universities in Tehran showed that in seven dimensions of knowledge flow of APQC, these libraries are far from desirable level and to achieve the ideal point, many activities in the field of knowledge flow need to be made, therefore suggestions were made in this study to reach the desired level. One Sample t Test in this research showed that these libraries are at a poor level in terms of these factors: in the dimensions of creation, identification and use of knowledge at a medium level and in the aspects of knowledge acquisition, review, sharing and access and also Manova test or Multivariable Analyze of Variance proved that there was no significant difference between the dimensions of knowledge flow between these libraries and the status of the knowledge flow in these libraries is at the same level as well. Except for the knowledge creation aspect that is slightly different in this regard that was mentioned before. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=knowledge%20flow" title="knowledge flow">knowledge flow</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20management" title=" knowledge management"> knowledge management</a>, <a href="https://publications.waset.org/abstracts/search?q=APQC" title=" APQC"> APQC</a>, <a href="https://publications.waset.org/abstracts/search?q=Tehran%E2%80%99s%20academic%20university%20libraries" title=" Tehran’s academic university libraries "> Tehran’s academic university libraries </a> </p> <a href="https://publications.waset.org/abstracts/129175/study-on-the-stages-of-knowledge-flow-in-central-libraries-of-tehran-universities-by-the-pattern-of-american-productivity-quality-center" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129175.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">164</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">293</span> Blockchain Solutions for IoT Challenges: Overview</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Ali%20Fatoorchi">Amir Ali Fatoorchi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Regardless of the advantage of LoT devices, they have limitations like storage, compute, and security problems.

Embedding the vectors into a sphere enabled us to take into consideration the antonymity between words, not only the synonymity, because of the suitability to handle the polarity nature of words. For example, a word and its antonym can be represented as a vector and its negative. Moreover, we have managed to extract an adequate vocabulary.

The XRD results showed that all samples have spinel phase and by increasing Bi content, the main diffraction peaks were shifted to higher angles, which means the lattice parameter decreases from 0.843 to 0.838 nm and then increases to 0.841 nm. Also, the results revealed that increasing Bi content lead to a decrease in saturation magnetization (Ms) from 74.9 to 48.8 emu/g and an increase in coercivity (Hc) from 96.8 to 137.1 Oe. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bi-substituted%20magnetite%20nanoparticles" title="bi-substituted magnetite nanoparticles">bi-substituted magnetite nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanochemical%20processing" title=" mechanochemical processing"> mechanochemical processing</a>, <a href="https://publications.waset.org/abstracts/search?q=X-ray%20diffraction" title=" X-ray diffraction"> X-ray diffraction</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetism" title=" magnetism"> magnetism</a> </p> <a href="https://publications.waset.org/abstracts/28462/synthesis-and-characterisation-of-bi-substituted-magnetite-nanoparticles-by-mechanochemical-processing-mcp" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28462.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">535</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">283</span> Effect of Adverse Pressure Gradient on a Fluctuating Velocity over the Co-Flow Jet Airfoil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Morteza%20Mirhosseini">Morteza Mirhosseini</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20B.%20Khoshnevis"> Amir B.

The proposed LNA uses a linearization technique to improve second and third-order intercept points (IIP3). The linearity is cured by repealing the common-mode section of all intermodulation components from the cascade topology current with optimization of biasing current use symmetrical and asymmetrical circuits for biasing. Simulation results show that maximum gain and noise figure are 6.9dB and 3.03-4.1dB over a 3.1–10.6 GHz, respectively. Power consumption of the LNA core and IIP3 are 2.64 mW and +4.9dBm respectively. The wideband input impedance matching of LNA is obtained by employing a degenerating inductor (|S11|<-9.1 dB).
