Blumberg</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Storm surge is an abnormal water level caused by a storm. Accurate prediction of a storm surge is a challenging problem. Researchers developed various ensemble modeling techniques to combine several individual forecasts to produce an overall presumably better forecast. There exist some simple ensemble modeling techniques in literature. For instance, Model Output Statistics (MOS), and running mean-bias removal are widely used techniques in storm surge prediction domain. However, these methods have some drawbacks. For instance, MOS is based on multiple linear regression and it needs a long period of training data. To overcome the shortcomings of these simple methods, researchers propose some advanced methods. For instance, ENSURF (Ensemble SURge Forecast) is a multi-model application for sea level forecast. This application creates a better forecast of sea level using a combination of several instances of the Bayesian Model Averaging (BMA). An ensemble dressing method is based on identifying best member forecast and using it for prediction. Our contribution in this paper can be summarized as follows. First, we investigate whether the ensemble models perform better than any single forecast. Therefore, we need to identify the single best forecast. We present a methodology based on a simple Bayesian selection method to select the best single forecast. Second, we present several new and simple ways to construct ensemble models. We use correlation and standard deviation as weights in combining different forecast models. Third, we use these ensembles and compare with several existing models in literature to forecast storm surge level. We then investigate whether developing a complex ensemble model is indeed needed. To achieve this goal, we use a simple average (one of the simplest and widely used ensemble model) as benchmark. Predicting the peak level of Surge during a storm as well as the precise time at which this peak level takes place is crucial, thus we develop a statistical platform to compare the performance of various ensemble methods. This statistical analysis is based on root mean square error of the ensemble forecast during the testing period and on the magnitude and timing of the forecasted peak surge compared to the actual time and peak. In this work, we analyze four hurricanes: hurricanes Irene and Lee in 2011, hurricane Sandy in 2012, and hurricane Joaquin in 2015. Since hurricane Irene developed at the end of August 2011 and hurricane Lee started just after Irene at the beginning of September 2011, in this study we consider them as a single contiguous hurricane event. The data set used for this study is generated by the New York Harbor Observing and Prediction System (NYHOPS). We find that even the simplest possible way of creating an ensemble produces results superior to any single forecast. We also show that the ensemble models we propose generally have better performance compared to the simple average ensemble technique. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bayesian%20learning" title="Bayesian learning">Bayesian learning</a>, <a href="https://publications.waset.org/abstracts/search?q=ensemble%20model" title=" ensemble model"> ensemble model</a>, <a href="https://publications.waset.org/abstracts/search?q=statistical%20analysis" title=" statistical analysis"> statistical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=storm%20surge%20prediction" title=" storm surge prediction"> storm surge prediction</a> </p> <a href="https://publications.waset.org/abstracts/70123/statistical-comparison-of-ensemble-based-storm-surge-forecasting-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70123.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">309</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">87</span> A Tale of Seven Districts: Reviewing The Past, Present and Future of Patent Litigation Filings to Form a Two-Step Burden-Shifting Framework for 28 U.S.C. § 1404(a)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Timothy%20T.%20Hsieh">Timothy T. Hsieh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Current patent venue transfer laws under 28 U.S.C. § 1404(a) e.g., the Gilbert factors from Gulf Oil Corp. v. Gilbert, 330 U.S. 501 (1947) are too malleable in that they often lead to frequent mandamus orders from the U.S. Court of Appeals for the Federal Circuit (“Federal Circuit”) overturning district court rulings on venue transfer motions. Thus, this paper proposes a more robust two-step burden-shifting framework that replaces the eight Gilbert factors. Moreover, a brief history of venue transfer patterns in the seven most active federal patent district courts is covered, with special focus devoted to the venue transfer orders from Judge Alan D Albright of the U.S. District Court for the Western District of Texas. A comprehensive data summary of 45 case sets where the Federal Circuit ruled on writs of mandamus involving Judge Albright’s transfer orders is subsequently provided, with coverage summaries of certain cases including four precedential ones from the Federal Circuit. This proposed two-step burden shifting framework is then applied to these venue transfer cases, as well as Federal Circuit mandamus orders ruling on those decisions. Finally, alternative approaches to remedying the frequent reversals for venue transfer will be discussed, including potential legislative solutions, adjustments to common law framework approaches to venue transfer, deference to the inherent powers of Article III U.S. District Judge, and a unified federal patent district court. Overall, this paper seeks to offer a more robust and consistent three-step burden-shifting framework for venue transfer and for the Federal Circuit to follow in administering mandamus orders, which might change somewhat in light of Western District of Texas Chief Judge Orlando Garcia’s order on redistributing Judge Albright’s patent cases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Patent%20law" title="Patent law">Patent law</a>, <a href="https://publications.waset.org/abstracts/search?q=venue" title=" venue"> venue</a>, <a href="https://publications.waset.org/abstracts/search?q=judge%20Alan%20Albright" title=" judge Alan Albright"> judge Alan Albright</a>, <a href="https://publications.waset.org/abstracts/search?q=minimum%20contacts" title=" minimum contacts"> minimum contacts</a>, <a href="https://publications.waset.org/abstracts/search?q=western%20district%20of%20Texas" title=" western district of Texas"> western district of Texas</a> </p> <a href="https://publications.waset.org/abstracts/164755/a-tale-of-seven-districts-reviewing-the-past-present-and-future-of-patent-litigation-filings-to-form-a-two-step-burden-shifting-framework-for-28-usc-1404a" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164755.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">109</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">86</span> Change of Internal Friction on Magnesium Alloy with 5.48% Al Dependence on the Temperature</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Milan%20Uhr%C3%AD%C4%8Dik">Milan Uhríčik</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Soviarov%C3%A1"> Andrea Soviarová</a>, <a href="https://publications.waset.org/abstracts/search?q=Zuzana%20Dresslerov%C3%A1"> Zuzana Dresslerová</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Pal%C4%8Dek"> Peter Palček</a>, <a href="https://publications.waset.org/abstracts/search?q=Alan%20Va%C5%A1ko"> Alan Vaško</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The article is focused on the analysis changes dependence on the temperature on the magnesium alloy with 5,48% Al, 0,813% Zn and 0,398% Mn by internal friction.

In order to delineate the border of undercut regions, orthogonal cutting planes are firstly employed to automatically find the inner loops of a part model. To discover the facets belonging to undercut regions, attributes are then assigned to the facets of the part model based on the topological relationship of adjacent facets of each inner loop. After that, the undercut regions are separated from other facets in the model. Through the recognized facets of the undercut regions, the concept of 'visibility map (V-map)' is further applied to determine feasible releasing directions for each of the undercut regions. The undercut regions having the same releasing direction are finally grouped to form a slider in the injection mold. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solid%20model" title="solid model">solid model</a>, <a href="https://publications.waset.org/abstracts/search?q=STL%20data" title=" STL data"> STL data</a>, <a href="https://publications.waset.org/abstracts/search?q=injection%20mold%20design" title=" injection mold design"> injection mold design</a>, <a href="https://publications.waset.org/abstracts/search?q=visibility%20map" title=" visibility map"> visibility map</a> </p> <a href="https://publications.waset.org/abstracts/11104/automatic-slider-design-in-injection-moldings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11104.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">395</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">81</span> Effect of Hot Rolling Conditions on Magnetic Properties of Fe-3%Si Non-Grain Oriented Electrical Steels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emre%20Alan">Emre Alan</a>, <a href="https://publications.waset.org/abstracts/search?q=Yusuf%20Yamanturk"> Yusuf Yamanturk</a>, <a href="https://publications.waset.org/abstracts/search?q=Gokay%20Bas"> Gokay Bas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Non-grain oriented electrical steels are high silicon containing steels in which the direction of magnetism is intended the same in any direction of the material.

The entire valve forging procedure was described and the possible cause of the fracture was proposed. Finite Element simulation was conducted for the forging process, with commercial Finite Element code DEFORMTM. The effects of material properties, the effect of strain rate and temperature were considered in the FE simulation. Two fracture criteria were discussed and compared, based on the accuracy and reliability of the FE simulation results. The selected criterion predicted the fracture location and shows the trend of damage increasing with good accuracy, which matches the experimental observation. Additional modification of the punch shapes was proposed to further reduce the tendency of fracture in forging. Finite Element comparison shows a great potential of such application in the mass production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hotforging" title="hotforging">hotforging</a>, <a href="https://publications.waset.org/abstracts/search?q=engine%20valve" title=" engine valve"> engine valve</a>, <a href="https://publications.waset.org/abstracts/search?q=fracture" title=" fracture"> fracture</a>, <a href="https://publications.waset.org/abstracts/search?q=tooling" title=" tooling"> tooling</a> </p> <a href="https://publications.waset.org/abstracts/23033/prediction-and-reduction-of-cracking-issue-in-precision-forging-of-engine-valves-using-finite-element-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23033.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">279</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">79</span> Determination of Steel Cleanliness of Non-Grain Oriented Electrical Steels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emre%20Alan">Emre Alan</a>, <a href="https://publications.waset.org/abstracts/search?q=Zafer%20Cetin"> Zafer Cetin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electrical steels are widely used as a magnetic core materials in many electrical applications such as transformers, electric motors, and generators. Core loss property of these magnetic materials refers to dissipation of electrical energy during magnetization in service conditions. Therefore, in order to minimize the magnetic core loss, certain precautions are taken from steel producers; “Steel Cleanliness” is one of the major points among them. For obtaining lower core loss values, increasing proper elements in chemical composition such as silicon is a must. Therefore, impurities of these alloys are a key value for producing a cleaner steel. In this study, effects of impurity levels of different FeSi alloying materials to the steel cleanliness will be investigated. One of the important element content in FeSi alloy materials is Calcium. A SEM investigation will be done in order to present if Ca content in FeSi alloy is enough for proper inclusion modification or an additional Ca-treatment is required. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrical%20steels" title="electrical steels">electrical steels</a>, <a href="https://publications.waset.org/abstracts/search?q=FeSi%20alloy" title=" FeSi alloy"> FeSi alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=impurities" title=" impurities"> impurities</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20cleanliness" title=" steel cleanliness"> steel cleanliness</a> </p> <a href="https://publications.waset.org/abstracts/56726/determination-of-steel-cleanliness-of-non-grain-oriented-electrical-steels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56726.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">334</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">78</span> Measurements of Chitin by Ochratoxigenic Fungi and Its Relationship to Ochratoxin a Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jamal%20Elzwai">Jamal Elzwai</a>, <a href="https://publications.waset.org/abstracts/search?q=Kofi%20Aidoo"> Kofi Aidoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Alan%20Candlish"> Alan Candlish</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Production of OTA was detected after 24hr by Aspergillus ochraceus isolate whereas at 36hr for A. carbonarius isolate and Penicillium verrucosum IMI 285522 and 60hr for A. ochraceus CBS 588.68. Highest OTA level was produced by A. carbonarius isolate followed by A. ochraceus CBS 588.68, Penicillium verrucosum IMI 285522 and finally A. ochraceus isolate. Glucosamine content of barley sample before fermentation was found to be negligible and remained almost constant during the incubation time.

This, however, seems not to affect major cooperates such as those in the telecommunication and energy sectors. Through their operations, they have not only been able to fluctuate prices at will but also they have been accused of curtailing their rivals from penetrating the market. This study, through literature review of the legal and institutional framework, reports and publications interrogates the law and uncovers the following; i) failings of the legal framework to define market dominance and abuse of such positions, ii) the participation of the state, iii) the inertia of the government to prosecute corporations that abuse their market dominance, iv) the role of the state as a market player and as a regulator through the Competition Authority of Kenya. This study concludes that the market distortion is as a result of weak legal and institutional framework as well as conflict of interest by the government.

When concrete compressive strength be larger than 31 MPa the limit of √(fc')/4fy usually governs. In this paper shortcomings related to using this limit was fairly discussed and showed that the limit is based on 90% safety factor and was derived based on modulus of rupture equation suitable for concretes of compressive strength lower than 31 MPa. Accordingly, the limit is nor suitable and critical for concretes of higher compressive strength. An alternative equation was proposed for minimum steel ratio of rectangular beams and was found that the proposed limit is accurate for beams of wide range of concrete compressive strength. Shortcomings of the current ACI 318 Code equation and accuracy of the proposed equation were supported by test data obtained from testing six reinforced concrete beams. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concrete%20beam" title="concrete beam">concrete beam</a>, <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title=" compressive strength"> compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=minimum%20steel%20ratio" title=" minimum steel ratio"> minimum steel ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=modulus%20of%20rupture" title=" modulus of rupture"> modulus of rupture</a> </p> <a href="https://publications.waset.org/abstracts/17902/minimum-ratio-of-flexural-reinforcement-for-high-strength-concrete-beams" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17902.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">550</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">75</span> The High Temperature Damage of DV–2 Turbine Blade Made from Ni–Base Superalloy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juraj%20Belan">Juraj Belan</a>, <a href="https://publications.waset.org/abstracts/search?q=Lenka%20Hurtalov%C3%A1"> Lenka Hurtalová</a>, <a href="https://publications.waset.org/abstracts/search?q=Eva%20Tillov%C3%A1"> Eva Tillová</a>, <a href="https://publications.waset.org/abstracts/search?q=Alan%20Va%C5%A1ko"> Alan Vaško</a>, <a href="https://publications.waset.org/abstracts/search?q=Milan%20Uhr%C3%AD%C4%8Dik"> Milan Uhríčik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> High-pressure turbine (HPT) blades of DV–2 jet engines are made from Ni–base superalloy, a former Soviet Union production, specified as ŽS6K.

This type of events can influence the oceanic/land interactions and even be related with climate changes. While the impact of such floods has been fairly studied in the North Atlantic, the impact of analog floods in the North Pacific remains debatable and relatively unknown. Here we will show records of the Missoula floods that have carved the Northwest landscape and have entered the North Pacific through the Columbia River. These records are given by the presence of high (more than 40%) percentages of freshwater diatoms in marine sediments. A regression equation using these percentages allows to estimate by how much the salinities decreased. The timing and impact of North Pacific megafloods recorded in three marine cores of Oregon and California for the past 25000 years (B.P.) will be presented. These records show that the volume of freshwater that entered the North Pacific reached as far as 600 Km south of the Columbia River Mouth, decreasing the salinities by as much as 4 units. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diatoms" title="diatoms">diatoms</a>, <a href="https://publications.waset.org/abstracts/search?q=megafloods" title=" megafloods"> megafloods</a>, <a href="https://publications.waset.org/abstracts/search?q=Missoula" title=" Missoula"> Missoula</a>, <a href="https://publications.waset.org/abstracts/search?q=North%20Pacific" title=" North Pacific"> North Pacific</a> </p> <a href="https://publications.waset.org/abstracts/103119/timing-and-impacts-of-megafloods-in-the-north-pacific-as-recorded-by-freshwater-diatoms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103119.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">172</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">73</span> Automated Buffer Box Assembly Cell Concept for the Canadian Used Fuel Packing Plant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dimitrie%20Marinceu">Dimitrie Marinceu</a>, <a href="https://publications.waset.org/abstracts/search?q=Alan%20Murchison"> Alan Murchison</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Canadian Used Fuel Container (UFC) is a mid-size hemispherical headed copper coated steel container measuring 2.5 meters in length and 0.5 meters in diameter containing 48 used fuel bundles. The contained used fuel produces significant gamma radiation requiring automated assembly processes to complete the assembly. The design throughput of 2,500 UFCs per year places constraints on equipment and hot cell design for repeatability, speed of processing, robustness and recovery from upset conditions. After UFC assembly, the UFC is inserted into a Buffer Box (BB). The BB is made from adequately pre-shaped blocks (lower and upper block) and Highly Compacted Bentonite (HCB) material. The blocks are practically ‘sandwiching’ the UFC between them after assembly. This paper identifies one possible approach for the BB automatic assembly cell and processes. Automation of the BB assembly will have a significant positive impact on nuclear safety, quality, productivity, and reliability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=used%20fuel%20packing%20plant" title="used fuel packing plant">used fuel packing plant</a>, <a href="https://publications.waset.org/abstracts/search?q=automatic%20assembly%20cell" title=" automatic assembly cell"> automatic assembly cell</a>, <a href="https://publications.waset.org/abstracts/search?q=used%20fuel%20container" title=" used fuel container"> used fuel container</a>, <a href="https://publications.waset.org/abstracts/search?q=buffer%20box" title=" buffer box"> buffer box</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20geological%20repository" title=" deep geological repository"> deep geological repository</a> </p> <a href="https://publications.waset.org/abstracts/75488/automated-buffer-box-assembly-cell-concept-for-the-canadian-used-fuel-packing-plant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75488.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">275</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">72</span> Cooperative Jamming for Implantable Medical Device Security</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kim%20Lytle">Kim Lytle</a>, <a href="https://publications.waset.org/abstracts/search?q=Tim%20Talty"> Tim Talty</a>, <a href="https://publications.waset.org/abstracts/search?q=Alan%20Michaels"> Alan Michaels</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeff%20Reed"> Jeff Reed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Implantable medical devices (IMDs) are medically necessary devices embedded in the human body that monitor chronic disorders or automatically deliver therapies. Most IMDs have wireless capabilities that allow them to share data with an offboard programming device to help medical providers monitor the patient’s health while giving the patient more insight into their condition. However, serious security concerns have arisen as researchers demonstrated these devices could be hacked to obtain sensitive information or harm the patient. Cooperative jamming can be used to prevent privileged information leaks by maintaining an adequate signal-to-noise ratio at the intended receiver while minimizing signal power elsewhere. This paper uses ray tracing to demonstrate how a low number of friendly nodes abiding by Bluetooth Low Energy (BLE) transmission regulations can enhance IMD communication security in an office environment, which in turn may inform how companies and individuals can protect their proprietary and personal information. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=implantable%20biomedical%20devices" title="implantable biomedical devices">implantable biomedical devices</a>, <a href="https://publications.waset.org/abstracts/search?q=communication%20system%20security" title=" communication system security"> communication system security</a>, <a href="https://publications.waset.org/abstracts/search?q=array%20signal%20processing" title=" array signal processing"> array signal processing</a>, <a href="https://publications.waset.org/abstracts/search?q=ray%20tracing" title=" ray tracing"> ray tracing</a> </p> <a href="https://publications.waset.org/abstracts/167002/cooperative-jamming-for-implantable-medical-device-security" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167002.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">112</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">71</span> Influence of Raw Material Composition on Microstructure and Mechanical Properties of Nodular Cast Iron </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alan%20Va%C5%A1ko">Alan Vaško</a>, <a href="https://publications.waset.org/abstracts/search?q=Juraj%20Belan"> Juraj Belan</a>, <a href="https://publications.waset.org/abstracts/search?q=Lenka%20Hurtalov%C3%A1"> Lenka Hurtalová</a>, <a href="https://publications.waset.org/abstracts/search?q=Eva%20Tillov%C3%A1"> Eva Tillová</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study is to evaluate the influence of raw material composition on the microstructure, mechanical and fatigue properties and micromechanisms of failure of nodular cast iron.

Most of this work focuses on models with different mean structures but leaves out the variance consideration. In this paper, we consider a regression model with multiplicative heteroscedasticity and develop a model averaging method that combines maximum likelihood estimators of unknown parameters in both the mean and variance functions of the model. Our weight choice criterion is based on a minimisation of a plug-in estimator of the model average estimator's squared prediction risk. We prove that the new estimator possesses an asymptotic optimality property. Our investigation of finite-sample performance by simulations demonstrates that the new estimator frequently exhibits very favourable properties compared to some existing heteroscedasticity-robust model average estimators. The model averaging method hedges against the selection of very bad models and serves as a remedy to variance function misspecification, which often discourages practitioners from modeling heteroscedasticity altogether.

The objective of this research is to evaluate the effectiveness of the air-quality-WRF-Chem model with a horizontal resolution of 5 km x 5 km. For this purpose, the measurements of the hourly SO₂ and O₃ concentrations available in three air quality monitoring stations in Lima, Peru were used for the purpose of validating the simulations of the SO₂ and O₃ concentrations obtained with the WRF-Chem model in February 2018. For the quantitative evaluation of the simulations of these gases, statistical techniques were implemented, such as the average of the simulations; the average of the measurements; the Mean Bias (MeB); the Mean Error (MeE); and the Root Mean Square Error (RMSE). The results of these statistical metrics indicated that the simulated SO₂ and O₃ values over-predicted the SO₂ and O₃ measurements. For the SO₂ concentration, the MeB values varied from 0.58 to 26.35 µg/m³; the MeE values varied from 8.75 to 26.5 µg/m³; the RMSE values varied from 13.3 to 31.79 µg/m³; while for O₃ concentrations the statistical values of the MeB varied from 37.52 to 56.29 µg/m³; the MeE values varied from 37.54 to 56.70 µg/m³; the RMSE values varied from 43.05 to 69.56 µg/m³. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ground-ozone" title="ground-ozone">ground-ozone</a>, <a href="https://publications.waset.org/abstracts/search?q=lima" title=" lima"> lima</a>, <a href="https://publications.waset.org/abstracts/search?q=sulphur%20dioxide" title=" sulphur dioxide"> sulphur dioxide</a>, <a href="https://publications.waset.org/abstracts/search?q=WRF-chem" title=" WRF-chem"> WRF-chem</a> </p> <a href="https://publications.waset.org/abstracts/154756/evaluating-hourly-sulphur-dioxide-and-ground-ozone-simulated-with-the-air-quality-model-in-lima-peru" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154756.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">137</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">66</span> A Proposal of Ontology about Brazilian Government Transparency Portal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Estela%20Mayra%20de%20Moura%20Vianna">Estela Mayra de Moura Vianna</a>, <a href="https://publications.waset.org/abstracts/search?q=Thiago%20Jos%C3%A9%20Tavares%20%C3%81vila"> Thiago José Tavares Ávila</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruno%20Morais%20Silva"> Bruno Morais Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Diego%20Henrique%20Bezerra"> Diego Henrique Bezerra</a>, <a href="https://publications.waset.org/abstracts/search?q=Paulo%20Henrique%20Gomes%20Silva"> Paulo Henrique Gomes Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Alan%20Pedro%20da%20Silva"> Alan Pedro da Silva</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Brazilian Federal Constitution defines the access to information as a crucial right of the citizen and the Law on Access to Public Information, which regulates this right. Accordingly, the Fiscal Responsibility Act, 2000, amended in 2009 by the “Law of Transparency”, began demanding a wider disclosure of public accounts for the society, including electronic media for public access. Thus, public entities began to create "Transparency Portals," which aim to gather a diversity of data and information. However, this information, in general, is still published in formats that do not simplify understanding of the data by citizens and that could be better especially available for audit purposes. In this context, a proposal of ontology about Brazilian Transparency Portal can play a key role in how these data will be better available. This study aims to identify and implement in ontology, the data model about Transparency Portal ecosystem, with emphasis in activities that use these data for some applications, like audits, press activities, social government control, and others. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=audit" title="audit">audit</a>, <a href="https://publications.waset.org/abstracts/search?q=government%20transparency" title=" government transparency"> government transparency</a>, <a href="https://publications.waset.org/abstracts/search?q=ontology" title=" ontology"> ontology</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20sector" title=" public sector"> public sector</a> </p> <a href="https://publications.waset.org/abstracts/14657/a-proposal-of-ontology-about-brazilian-government-transparency-portal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14657.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">506</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">65</span> Assessing Student Attitudes toward Graded Readers, MReader and the MReader Challenge </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Catherine%20Cheetam">Catherine Cheetam</a>, <a href="https://publications.waset.org/abstracts/search?q=Alan%20Harper"> Alan Harper</a>, <a href="https://publications.waset.org/abstracts/search?q=Melody%20Elliott"> Melody Elliott</a>, <a href="https://publications.waset.org/abstracts/search?q=Mika%20Ito"> Mika Ito</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper describes a pilot study conducted with English as a foreign language (EFL) students at a private university in Japan who used graded readers and the MReader website in class or independently to enhance their English reading skills. Each semester students who read 100,000 words with MReader quizzes passed enter into the ‘MReader Challenge,’ a reading contest that recognizes students for their achievement. The study focused specifically on the attitudes of thirty-six EFL students who successfully completed the Challenge in the 2015 spring semester using graded readers and MReader, and their motivation to continue using English in the future. The attitudes of these students were measured using their responses to statements on a Likert scaled survey. Follow-up semi-structured interviews were conducted with eleven students to gain additional insight into their opinions. The results from this study suggest that reading graded readers in general promoted intrinsic motivation among a majority of the participants. This study is preliminary and needs to be expanded and continued to assess the lasting impact of the extensive reading program.

Participants were aged 18 to 72 years. 94% of the participants saw faces in the front-end design of production models. All participants that recognized faces indicated that most styles showed some degree of an angry expression. It was found that women were more likely to see faces in inanimate objects. However, with respect to whether women were more likely to perceive anger in the vehicle design, the results need further clarification. Survey responses were correlated to the design features of vehicles to determine what cues the respondents were likely looking at when responding. Whether the features looked anthropomorphic was key to anger perception. Features such as the headlights which could represent eyes and the air intake that could represent a mouth had high correlations to trends in scores. Results are compared among models, makers, by groupings of body styles classifications for the top 12 brands sold in the US, and by year for the top 20 models sold in the US in 2016. All of the top models sold increased in perception of an angry expression over the last 20 years or since the model was introduced, but the relative change varied by body style grouping. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aggressive%20driving" title="aggressive driving">aggressive driving</a>, <a href="https://publications.waset.org/abstracts/search?q=face%20recognition" title=" face recognition"> face recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=road%20rage" title=" road rage"> road rage</a>, <a href="https://publications.waset.org/abstracts/search?q=vehicle%20styling" title=" vehicle styling"> vehicle styling</a> </p> <a href="https://publications.waset.org/abstracts/88607/pareidolia-and-perception-of-anger-in-vehicle-styles-survey-results" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88607.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">140</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">63</span> Temporal Trends in the Urban Metabolism of Riyadh, Saudi Arabia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naif%20Albelwi">Naif Albelwi</a>, <a href="https://publications.waset.org/abstracts/search?q=Alan%20Kwan"> Alan Kwan</a>, <a href="https://publications.waset.org/abstracts/search?q=Yacine%20Rezgui"> Yacine Rezgui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cities with rapid growth face tremendous challenges not only to provide services to meet this growth but also to assure that this growth occurs in a sustainable way. The consumption of material, energy, and water resources is inextricably linked to population growth with a unique impact in urban areas, especially in light of significant investments in infrastructure to support urban development. Urban Metabolism (UM) is becoming popular as it provides a framework accounting the mass and energy flows through a city. The objective of this study is to determine the energy and material flows of Riyadh, Saudi Arabia using locally generated data from 1996 and 2012 and analyzing the temporal trends of energy and material flows. Preliminary results show that while the population of Riyadh grew 90% since 1996, the input and output flows have increased at higher rate. Results also show increasing in energy mobile consumption from 61k TJ in 1996 to 157k TJ in 2012 which points to Riyadh’s inefficient urban form. The study findings highlight the importance to develop effective policies for improving the use of resources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20and%20water%20consumption" title="energy and water consumption">energy and water consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20development" title=" urban development"> urban development</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20metabolism" title=" urban metabolism"> urban metabolism</a> </p> <a href="https://publications.waset.org/abstracts/55550/temporal-trends-in-the-urban-metabolism-of-riyadh-saudi-arabia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55550.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">272</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">62</span> A Review of Test Protocols for Assessing Coating Performance of Water Ballast Tank Coatings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20A.%20Oriaifo">Emmanuel A.

Test protocols/methodologies specifically that which is incorporated in the International Maritime Organisation (IMO), Performance Standard for Protective Coatings for Dedicated Sea Water ballast tanks (PSPC) are being used to assess and evaluate the performance of the coatings for type approval prior to their application in WBTs. However, some of the type approved coatings may be applied as very thick films to less than ideally prepared steel substrates in the WBT. As such films experience hygrothermal cycling from operating and environmental conditions, they become embrittled which may ultimately result in cracking. This embrittlement of the coatings is identified as an undesirable feature in the PSPC but is not mentioned in the test protocols within it. There is therefore renewed industrial research aimed at understanding this issue in order to eliminate cracking and achieve the intended coating lifespan of 15 years in good condition. This paper will critically review test protocols currently used for assessing and evaluating coating performance, particularly the IMO PSPC. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corrosion%20test" title="corrosion test">corrosion test</a>, <a href="https://publications.waset.org/abstracts/search?q=hygrothermal%20cycling" title=" hygrothermal cycling"> hygrothermal cycling</a>, <a href="https://publications.waset.org/abstracts/search?q=coating%20test%20protocols" title=" coating test protocols"> coating test protocols</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20ballast%20tanks" title=" water ballast tanks"> water ballast tanks</a> </p> <a href="https://publications.waset.org/abstracts/10871/a-review-of-test-protocols-for-assessing-coating-performance-of-water-ballast-tank-coatings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10871.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">434</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">61</span> Dyeing of Polyester/Cotton Blends with Reverse-Micelle Encapsulated High Energy Disperse/Reactive Dye Mixture </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chi-Wai%20Kan">Chi-Wai Kan</a>, <a href="https://publications.waset.org/abstracts/search?q=Yanming%20%20Wang"> Yanming Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Alan%20Yiu-Lun%20%20Tang"> Alan Yiu-Lun Tang</a>, <a href="https://publications.waset.org/abstracts/search?q=Cheng-Hao%20Lee%20%20Lee"> Cheng-Hao Lee Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dyeing of polyester/cotton blend fabrics in various polyester/cotton percentages (32/68, 40/60 and 65/35) was investigated using (poly(ethylene glycol), PEG) based reverse-micelle.

This issue becomes even more interesting if the raw material for the fuel production can be obtained as the result of that recycling. A process of high-temperature decomposition of a lignite (a non-hydrolysable complex organic compound) was studied on the plasma gasification reactor PLASGAS, where water-stabilized plasma torch was used as a source of high enthalpy plasma. The plasma torch power was 120 kW and allowed heating of the reactor to more than 1000 °C. The material feeding rate in the gasification reactor was selected 30 and 60 kg per hour that could be compared with small industrial production. An efficiency estimation of the thermal decomposition process was done. A balance of the torch energy distribution was studied as well as an influence of the lignite particle size and an addition of methane (CH4) in a reaction volume on the syngas composition (H2+CO). It was found that the ratio H2:CO had values in the range of 1,5 to 2,5 depending on the experimental conditions. The recycling process occurred at atmospheric pressure that was one of the important benefits because of the lack of expensive vacuum pump systems. The work was supported by the Grant Agency of the Czech Republic under the project GA15-19444S. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atmospheric%20pressure" title="atmospheric pressure">atmospheric pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=lignite" title=" lignite"> lignite</a>, <a href="https://publications.waset.org/abstracts/search?q=plasma%20treatment" title=" plasma treatment"> plasma treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=water-stabilized%20plasma%20torch" title=" water-stabilized plasma torch"> water-stabilized plasma torch</a> </p> <a href="https://publications.waset.org/abstracts/47529/plasma-treatment-of-a-lignite-using-water-stabilized-plasma-torch-at-atmospheric-pressure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47529.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">373</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">59</span> Bystanders' Behavior during Emergencies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alan%20%28Avi%29%20Kirschenbaum">Alan (Avi) Kirschenbaum</a>, <a href="https://publications.waset.org/abstracts/search?q=Carmit%20Rapaport"> Carmit Rapaport</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The behavior of bystanders in emergencies and disasters have been examined for over 50 years. Such acts have been cited as contributing to saving lives in terms of providing first responder help until official emergency units can arrive. Several reasons have been suggested for this type of behavior but most focused on a broad segment of individual psychological decision-making processes. Recent theoretical evidence suggests that the external factors for such bystander decisions, mainly disaster community based social contexts factors, are also important. We aim to test these competing arguments. Specifically, we examine alternative explanatory perspectives by focusing on self-efficacy as a proxy for the accepted individual psychological case and contrast it with potential bystander characteristics of the individual as well factors as embedded in the social context of the disaster community. To do so, we will utilize a random sampling of the population from a field study of an urban community in Israel that experienced five years of continuous terror attacks. The results strongly suggest that self-efficacy, as well as external factors: preparedness and having skills for intervention during emergencies along with gender best, predict potential helping behaviors. These results broaden our view of bystander behavior and open a window for enhancing this phenomenon as another element in disaster and crisis management. <p
