It is predicted that the IoT will influence every aspect of our lifestyles in the near future. Wireless Sensor Networks are one of the key enablers of the operation of IoTs, allowing data to be collected from the surrounding environment. However, due to limited resources, nature of deployment and unattended operation, a WSN is vulnerable to various types of attack. Security is paramount for reliable and safe communication between IoT embedded devices, but it does, however, come at a cost to resources. Nodes are usually equipped with small batteries, which makes energy conservation crucial to IoT devices. Nevertheless, security cost in terms of energy consumption has not been studied sufficiently. Previous research has used a security specification of 802.15.4 for IoT applications, but the energy cost of each security level and the impact on quality of services (QoS) parameters remain unknown. This research focuses on the cost of security at the IoT media access control (MAC) layer. It begins by studying the energy consumption of IEEE 802.15.4 security levels, which is followed by an evaluation for the impact of security on data latency and throughput, and then presents the impact of transmission power on security overhead, and finally shows the effects of security on memory footprint. The results show that security overhead in terms of energy consumption with a payload of 24 bytes fluctuates between 31.5% at minimum level over non-secure packets and 60.4% at the top security level of 802.15.4 security specification. Also, it shows that security cost has less impact at longer packet lengths, and more with smaller packet size. In addition, the results depicts a significant impact on data latency and throughput. Overall, maximum authentication length decreases throughput by almost 53%, and encryption and authentication together by almost 62%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20consumption" title="energy consumption">energy consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=IEEE%20802.15.4" title=" IEEE 802.15.4"> IEEE 802.15.4</a>, <a href="https://publications.waset.org/abstracts/search?q=IoT%20security" title=" IoT security"> IoT security</a>, <a href="https://publications.waset.org/abstracts/search?q=security%20cost%20evaluation" title=" security cost evaluation"> security cost evaluation</a> </p> <a href="https://publications.waset.org/abstracts/82993/the-security-trade-offs-in-resource-constrained-nodes-for-iot-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82993.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">168</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">36</span> The Relationships between Autonomy-Based Insula Activity and Learning: A Functional Magnetic Resonance Imaging Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Woogul%20Lee">Woogul Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Johnmarshall%20Reeve"> Johnmarshall Reeve</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Learners’ perceived autonomy predicts learners’ interest, engagement, and learning. To understand these processes, we conducted an fMRI experiment. In this experiment, participants saw the national flag and were asked to rate how much they freely wanted to learn about that particular national flag. The participants then learned the characteristics of the national flag. Results showed that (1) the degree of participants’ perceived autonomy was positively correlated with the degree of insula activity, (2) participants’ early-trial insula activity predicted corresponding late-trial dorsolateral prefrontal cortex activity, and (3) the degree of dorsolateral prefrontal cortex activity was positively correlated with the degree of participants’ learning about the characteristics of the national flag. Results suggest that learners’ perceived autonomy predicts learning through the mediation of insula activity associated with intrinsic satisfaction and 'pure self' processes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=insular%20cortex" title="insular cortex">insular cortex</a>, <a href="https://publications.waset.org/abstracts/search?q=autonomy" title=" autonomy"> autonomy</a>, <a href="https://publications.waset.org/abstracts/search?q=self-determination" title=" self-determination"> self-determination</a>, <a href="https://publications.waset.org/abstracts/search?q=dorsolateral%20prefrontal%20cortex" title=" dorsolateral prefrontal cortex"> dorsolateral prefrontal cortex</a> </p> <a href="https://publications.waset.org/abstracts/73516/the-relationships-between-autonomy-based-insula-activity-and-learning-a-functional-magnetic-resonance-imaging-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73516.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">204</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">35</span> The Employer Brand as Perceived by Salespeople: A Study Based on Glassdoor Reviews </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juliet%20F.%20Poujol">Juliet F.

Results show that traditional motivators like opportunities of advancement, and 'hygiene' factors such as benefits and work conditions are a source of satisfaction for salespeople. We also found differences by sectors.

Not only that excessive overtopping is reported for impermeable seawalls under bimodal waves, but overtopping is also showing a high sensitivity to the peakedness of the random wave propagation patterns. In the present study, we present a comprehensive analysis of the effects of peakedness of bimodal wave patterns of the overtopping of sloping seawalls. An energy-conserved bimodal spectrum with four different spectra peak periods and swell percentages was applied to estimate wave overtopping in both numerical and experimental flumes. Results of incident surface elevations and bimodal spectra were accurately captured across the flume domain using sets of well-positioned resistant-type wave gauges. Peakedness characteristics of the wave patterns were extracted to derive a relationship between the non-dimensional overtopping and the peakedness across the wave groups in the wave series. The full paper will briefly describe the development of the spectrum and present a comprehensive results analysis leading to the derivation of the relationship between dimensionless overtopping and peakedness of bimodal waves. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wave%20overtopping" title="wave overtopping">wave overtopping</a>, <a href="https://publications.waset.org/abstracts/search?q=peakedness" title=" peakedness"> peakedness</a>, <a href="https://publications.waset.org/abstracts/search?q=bimodal%20waves" title=" bimodal waves"> bimodal waves</a>, <a href="https://publications.waset.org/abstracts/search?q=swell%20percentages" title=" swell percentages"> swell percentages</a> </p> <a href="https://publications.waset.org/abstracts/141281/effects-of-peakedness-of-bimodal-waves-on-overtopping-of-sloping-seawalls" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141281.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">181</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">33</span> Exposing Latent Fingermarks on Problematic Metal Surfaces Using Time of Flight Secondary Ion Mass Spectroscopy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tshaiya%20Devi%20Thandauthapani">Tshaiya Devi Thandauthapani</a>, <a href="https://publications.waset.org/abstracts/search?q=Adam%20J.%20Reeve"> Adam J.

However, visualising latent (hidden) fingermarks can be difficult, and the correct choice of techniques is essential to develop and preserve any fingermarks that might be present. Knives, firearms and other metal weapons have proven to be challenging substrates (stainless steel in particular) from which to reliably obtain fingermarks. In this study, time of flight secondary ion mass spectroscopy (ToF-SIMS) was used to image fingermarks on metal surfaces. This technique was compared to a conventional superglue based fuming technique that was accompanied by a series of contrast enhancing dyes (basic yellow 40 (BY40), crystal violet (CV) and Sudan black (SB)) on three different metal surfaces. The conventional techniques showed little to no evidence of fingermarks being present on the metal surfaces after a few days. However, ToF-SIMS images revealed fingermarks on the same and similar substrates with an exceptional level of detail demonstrating clear ridge definition as well as detail about sweat pore position and shape, that persist for over 26 days after deposition when the samples were stored under ambient conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conventional%20techniques" title="conventional techniques">conventional techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=latent%20fingermarks" title=" latent fingermarks"> latent fingermarks</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20substrates" title=" metal substrates"> metal substrates</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20of%20flight%20secondary%20ion%20mass%20spectroscopy" title=" time of flight secondary ion mass spectroscopy "> time of flight secondary ion mass spectroscopy </a> </p> <a href="https://publications.waset.org/abstracts/97702/exposing-latent-fingermarks-on-problematic-metal-surfaces-using-time-of-flight-secondary-ion-mass-spectroscopy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97702.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">32</span> A Dynamic Spatial Panel Data Analysis on Renter-Occupied Multifamily Housing DC</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jose%20Funes">Jose Funes</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeff%20Sauer"> Jeff Sauer</a>, <a href="https://publications.waset.org/abstracts/search?q=Laixiang%20Sun"> Laixiang Sun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research examines determinants of multifamily housing development and spillovers in the District of Columbia.

There is no doubt that eyewitness statements can be an important component to an investigation, particularly when other evidence is sparse, as is often the case when damage to the scene is severe. However, it is well known that eyewitness statements can be incorrect for a variety of reasons, including deception. In this paper, we reviewed factors that can have an effect on the complex processes associated with the perception, retention, and retrieval of an event. We then review the accuracy of eyewitness statements from unique criminal and civil incidents, including fire and explosion incidents, in which the accuracy of the statements could be independently evaluated. Finally, the motives for deceptive eyewitness statements are described, along with techniques that fire and explosion investigators can employ, to increase the accuracy of the eyewitness statements that they solicit. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fire" title="fire">fire</a>, <a href="https://publications.waset.org/abstracts/search?q=explosion" title=" explosion"> explosion</a>, <a href="https://publications.waset.org/abstracts/search?q=eyewitness" title=" eyewitness"> eyewitness</a>, <a href="https://publications.waset.org/abstracts/search?q=reliability" title=" reliability"> reliability</a> </p> <a href="https://publications.waset.org/abstracts/143632/reliability-of-eyewitness-statements-in-fire-and-explosion-investigations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143632.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">382</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">30</span> COVID-19, Employee Perspectives, and the Shifting Nature of Work</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jonathan%20H.%20Westover">Jonathan H.

Podcasting is a popular method for sharing information. The purpose of this study was to examine the impact of student motivation and the perception of the acquisition of knowledge in an online environment of a skill-based class. 25 students in a school psychology graduate class completed a pretest and posttest examining podcast use and familiarity. In addition, at the completion of the course they were administered a modified version of the Instructional Materials Motivation Survey. The four subscales were examined (attention, relevance, confidence, and satisfaction). Results indicated that students are motivated, they perceive podcasts as positive instructional tools, and students are successful in acquiring the needed information. Additional benefits of using podcasts and recommendations in school psychology training are discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=motivation" title="motivation">motivation</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20learning" title=" online learning"> online learning</a>, <a href="https://publications.waset.org/abstracts/search?q=pedagogy" title=" pedagogy"> pedagogy</a>, <a href="https://publications.waset.org/abstracts/search?q=podcast" title=" podcast"> podcast</a> </p> <a href="https://publications.waset.org/abstracts/125888/podcasting-as-an-instructional-method-case-study-of-a-school-psychology-class" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125888.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">131</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">28</span> Trust and Conflict Resolution: Relationship Building for Learning </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeff%20Dickie">Jeff Dickie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research paper combined grounded coding and research questions with the objective to investigate conflict resolution in the classroom. The students’ answers concerning teaching were coded according to phrasal meanings which revealed concepts. These concept codes then became input data into theoretical frameworks. The investigation indicated two conflicts: whether the information was valid and whether to make the study effort which was discussed as perceptions of teacher’s competence in helping to learn. The relevant factors in helping to learn were predominately emotional. These factors were important in the negotiation process to develop relationships. Information validity seemed to be the motivator to begin and participate effectively with the learning process. In effect, confidence in the learning negotiation process with the focus towards relationship building with the subject matter seemed to be the motivator to make the study effort. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coding" title="coding">coding</a>, <a href="https://publications.waset.org/abstracts/search?q=confidence" title=" confidence"> confidence</a>, <a href="https://publications.waset.org/abstracts/search?q=competence" title=" competence"> competence</a>, <a href="https://publications.waset.org/abstracts/search?q=conflict%20resolution" title=" conflict resolution"> conflict resolution</a>, <a href="https://publications.waset.org/abstracts/search?q=risk" title=" risk"> risk</a>, <a href="https://publications.waset.org/abstracts/search?q=trust" title=" trust"> trust</a>, <a href="https://publications.waset.org/abstracts/search?q=relationship%20building" title=" relationship building "> relationship building </a> </p> <a href="https://publications.waset.org/abstracts/18286/trust-and-conflict-resolution-relationship-building-for-learning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18286.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">431</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> Fabrication of Wearable Antennas through Thermal Deposition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeff%20Letcher">Jeff Letcher</a>, <a href="https://publications.waset.org/abstracts/search?q=Dennis%20Tierney"> Dennis Tierney</a>, <a href="https://publications.waset.org/abstracts/search?q=Haider%20Raad"> Haider Raad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Antennas are devices for transmitting and/or receiving signals which make them a necessary component of any wireless system. In this paper, a thermal deposition technique is utilized as a method to fabricate antenna structures on substrates. Thin-film deposition is achieved by evaporating a source material (metals in our case) in a vacuum which allows vapor particles to travel directly to the target substrate which is encased with a mask that outlines the desired structure. The material then condenses back to solid state. This method is used in comparison to screen printing, chemical etching, and ink jet printing to indicate advantages and disadvantages to the method. The antenna created undergoes various testing of frequency ranges, conductivity, and a series of flexing to indicate the effectiveness of the thermal deposition technique. A single band antenna that is operated at 2.45 GHz intended for wearable and flexible applications was successfully fabricated through this method and tested. It is concluded that thermal deposition presents a feasible technique of producing such antennas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermal%20deposition" title="thermal deposition">thermal deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=wearable%20antennas" title=" wearable antennas"> wearable antennas</a>, <a href="https://publications.waset.org/abstracts/search?q=bluetooth%20technology" title=" bluetooth technology"> bluetooth technology</a>, <a href="https://publications.waset.org/abstracts/search?q=flexible%20electronics" title=" flexible electronics"> flexible electronics</a> </p> <a href="https://publications.waset.org/abstracts/56810/fabrication-of-wearable-antennas-through-thermal-deposition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56810.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">26</span> Applying Bowen’s Theory to Intern Supervision</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeff%20A.%20Tysinger">Jeff A.

The school psychology internship is the capstone experience for the school psychologist in training. It involves three key participants whose relationships will determine the success of the internship.  To understand the potential effect, Bowen’s family systems theory can be applied to the supervision relationship. He describes a way to resolve stress between two people by triangulating or binging in a third person. He applies this to a nuclear family, but school psychology intern supervision requires the marriage of an intern, field supervisor, and university supervisor; thus, setting all up for possible triangulation. The consequences of triangulation can apply to standards and requirements, direct supervision, and intern evaluation. Strategies from family systems theory to decrease the negative impact of supervision triangulation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=family%20systems%20theory" title="family systems theory">family systems theory</a>, <a href="https://publications.waset.org/abstracts/search?q=intern%20supervision" title=" intern supervision"> intern supervision</a>, <a href="https://publications.waset.org/abstracts/search?q=school%20psychology%20training" title=" school psychology training"> school psychology training</a>, <a href="https://publications.waset.org/abstracts/search?q=triangulation" title=" triangulation"> triangulation</a> </p> <a href="https://publications.waset.org/abstracts/125889/applying-bowens-theory-to-intern-supervision" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125889.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">126</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">25</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">114</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">24</span> Chemical Durability of Textured Glass-coat Suitable for Building Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adejo%20Andrew%20Ojonugwa">Adejo Andrew Ojonugwa</a>, <a href="https://publications.waset.org/abstracts/search?q=Jomboh%20Jeff%20Kator"> Jomboh Jeff Kator</a>, <a href="https://publications.waset.org/abstracts/search?q=Garkida%20Adele%20Dzikwi"> Garkida Adele Dzikwi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study investigates the behaviour of textured glass coat to chemical reactions upon application.

Bioassay data and chemical structures from pharmacokinetic and drug metabolism screening are mined from and housed in multiple databases. Bioassay prediction is calculated accordingly to determine further advancement. This paper proposes a four-step preprocessing of datasets for improving the bioassay predictions. The first step is instance selection in which dataset is categorized into training, testing, and validation sets. The second step is discretization that partitions the data in consideration of accuracy vs. precision. The third step is normalization where data are normalized between 0 and 1 for subsequent machine learning processing. The fourth step is feature selection where key chemical properties and attributes are generated. The streamlined results are then analyzed for the prediction of effectiveness by various machine learning algorithms including Pipeline Pilot, R, Weka, and Excel. Experiments and evaluations reveal the effectiveness of various combination of preprocessing steps and machine learning algorithms in more consistent and accurate prediction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bioassay" title="bioassay">bioassay</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=preprocessing" title=" preprocessing"> preprocessing</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20screen" title=" virtual screen"> virtual screen</a> </p> <a href="https://publications.waset.org/abstracts/77481/optimized-preprocessing-for-accurate-and-efficient-bioassay-prediction-with-machine-learning-algorithms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77481.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">274</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">22</span> The Depiction of Suburbia in US-American Independent Movies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sven%20Weidner">Sven Weidner</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the last two decades, US-American Independent Cinema has been faced with numerous metamorphoses. With regard to style, content, film aesthetics and themes a large array is offered. And as a consequence of the increasing influence of the world wide web and absolutely new ways of production opportunities alter the indie-film scene fundamentally. While in the 90s many independent films were situated in urban spaces -for instance, films of Jim Jarmusch, Abel Ferrara or Quentin Tarantino- there is a tendency from the 2000s years on to go to rural America. Jeff Nichols, Debra Granik or Matthew Porterfield can be named. Suburbia the symbol of the American Dream and in particular of an emerging prosperity after the Second World War is an essential theme with some independent directors; among them indie icons Todd Solondz and Todd Haynes. Based on selected films of both of them the paper explores the formal and aesthetic structures (narrative, drama, montage, lighting, sound, color) of the pictures and how suburbia, its people, and its "perfect" families are shown and unmasked in all facets. Films are: "Happiness" (1998), "Life During Wartime" (2009) and "Far From Heaven" (2002). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=US-independent%20cinema" title="US-independent cinema">US-independent cinema</a>, <a href="https://publications.waset.org/abstracts/search?q=Suburbia" title=" Suburbia"> Suburbia</a>, <a href="https://publications.waset.org/abstracts/search?q=film%20history" title=" film history"> film history</a>, <a href="https://publications.waset.org/abstracts/search?q=film%20analysis" title=" film analysis"> film analysis</a> </p> <a href="https://publications.waset.org/abstracts/58663/the-depiction-of-suburbia-in-us-american-independent-movies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58663.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">267</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">21</span> Portrayal of Pak-US Relations in Perspective of Bin Laden Killing by the Leading American and British Newspapers: A Content Analysis of the Guardian, the Telegraph, Washington Post and the New York Times</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shahzad%20Ali">Shahzad Ali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article expounds the coverage of Pak-US relations in the context of Osama Bin Laden killing in four selected leading newspapers of UK and the US viz The Telegraph, The Guardian, The New York Times and The Washington Post during the specific time period of three months, i.e., April-June, 2011. The study is scrutinized on the basis of Operation Neptune Spear. The research study is theoretically linked with the propaganda model of Herman and Chomsky and the Shoemaker and Reeve‘s theory of content effect, specifically the impact of foreign policy as a driving instrument influencing the nature and treatment of the coverage of Pak-US relations. The relations between Pakistan and USA are of great importance in the context of Bin Laden. The Pak-US relations were less aggravated and hostile in pre OBL period but post OBL period worsened these relations. It is also interesting to mention that the policies of these newspapers were dependent on the foreign policy of their countries. It was explored that the news coverage was found favorable as and when the relations Pakistan and the US or UK were cordial and smooth. And it turned into negative and unfavorable when the relations were in strain and deteriorating and endorsed various studies that the Western mainstream media tried to be more nationalistic in projecting official stance while covering foreign coverage instead of adhering to universal cannon of journalism, i.e., objectivity, fairness, and neutrality, etc. Overall 219 news items of these four selected newspapers regarding Pak-US relations in the context of pre and post OBL’s killing operation were undertaken for analysis. The ratio of negative slants was found higher as compared to the positive and neutral slants. Besides, the ratio of news items with unfavorable frames was found higher in post OBL operation in comparison of pre-era of the coverage related to Pak-US relations in the leading British and American newspapers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Osama%20Bin%20Laden" title="Osama Bin Laden">Osama Bin Laden</a>, <a href="https://publications.waset.org/abstracts/search?q=Pakistan" title=" Pakistan"> Pakistan</a>, <a href="https://publications.waset.org/abstracts/search?q=USA" title=" USA"> USA</a>, <a href="https://publications.waset.org/abstracts/search?q=UK" title=" UK"> UK</a>, <a href="https://publications.waset.org/abstracts/search?q=relations" title=" relations"> relations</a>, <a href="https://publications.waset.org/abstracts/search?q=Guardian" title=" Guardian"> Guardian</a>, <a href="https://publications.waset.org/abstracts/search?q=Washington%20Post" title=" Washington Post"> Washington Post</a>, <a href="https://publications.waset.org/abstracts/search?q=Telegraph" title=" Telegraph"> Telegraph</a>, <a href="https://publications.waset.org/abstracts/search?q=New%20York%20Times" title=" New York Times"> New York Times</a>, <a href="https://publications.waset.org/abstracts/search?q=Operation%20Neptune%20Spear" title=" Operation Neptune Spear"> Operation Neptune Spear</a> </p> <a href="https://publications.waset.org/abstracts/104962/portrayal-of-pak-us-relations-in-perspective-of-bin-laden-killing-by-the-leading-american-and-british-newspapers-a-content-analysis-of-the-guardian-the-telegraph-washington-post-and-the-new-york-times" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104962.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">171</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> Progress and Challenges of Smart Cities in India: An Exploratory Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sushil%20K.%20Sharma">Sushil K.

Over 700 cities from around the world have already started implementing their smart city projects. Smart City utilizes the network of connected things, or the Internet of Things (IoT), that interconnects devices and various components across city infrastructure, making them work together seamlessly to enhance the quality, performance, and interactivity of urban services, optimize resources, and reduce costs. Without developing smart cities, the accelerating growth of cities, and their disproportionate consumption of physical and social resources are unsustainable. In 2016, the Indian Government released a list of 100 cities with the intention of kick-starting the process of developing them into 'smart cities’ as part of the Smart Cities Mission. This study reports the progress and challenges of Smart City projects in India. The data were collected through the city/state government websites, media reports, and focus group discussions/interviews. The preliminary results indicate that smart city projects are not only behind in their implementation and scope but also lacks the sincerity for its implementation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=smart%20city" title="smart city">smart city</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20government" title=" smart government"> smart government</a>, <a href="https://publications.waset.org/abstracts/search?q=Internet%20of%20Things" title=" Internet of Things"> Internet of Things</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20government" title=" digital government"> digital government</a> </p> <a href="https://publications.waset.org/abstracts/119755/progress-and-challenges-of-smart-cities-in-india-an-exploratory-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/119755.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">182</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">19</span> Structural, Magnetic and Thermodynamic Investigation of Iridium Double Perovskites with Ir⁵⁺</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mihai%20I.%20Sturza">Mihai I.

Structural, magnetic and thermodynamic investigations of Sr₂YIrO₆ and Ba2YIrO6 single crystals, with emphasis on the temperature and magnetic field dependence of the specific heat will be presented. The single crystals were grown by using SrCl₂ and BaCl₂ as flux. Single-crystal X-ray diffraction measurements performed on several crystals from different preparation batches showed a high quality of the crystals, proven by the good internal consistency of the data collected using the full-sphere mode and an extremely low R factor. In agreement with the expected non-magnetic ground state of Ir⁵⁺ (5d4) in these iridates, no magnetic transition is observed down to 430 mK. Moreover, our results suggest that the low-temperature anomaly observed in the specific heat is not related to the onset of long-range magnetic order. Instead, it is identified as a Schottky anomaly caused by paramagnetic impurities present in the sample, of the order of <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=double%20perovskites" title="double perovskites">double perovskites</a>, <a href="https://publications.waset.org/abstracts/search?q=iridates" title=" iridates"> iridates</a>, <a href="https://publications.waset.org/abstracts/search?q=self-flux%20grown%20synthesis" title=" self-flux grown synthesis"> self-flux grown synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=spin-orbit%20coupling" title=" spin-orbit coupling"> spin-orbit coupling</a> </p> <a href="https://publications.waset.org/abstracts/64309/structural-magnetic-and-thermodynamic-investigation-of-iridium-double-perovskites-with-ir5" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64309.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">330</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">18</span> Evaluation of Nitrogen Fixation Capabilities of Selected Pea Lines Grown under Different Environmental Conditions in Canadian Prairie</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chao%20Yang">Chao Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Rosalind%20Bueckert"> Rosalind Bueckert</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeff%20Schoenau"> Jeff Schoenau</a>, <a href="https://publications.waset.org/abstracts/search?q=Axel%20Diederichsen"> Axel Diederichsen</a>, <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Zakeri"> Hossein Zakeri</a>, <a href="https://publications.waset.org/abstracts/search?q=Tom%20Warkentin"> Tom Warkentin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pea is a very popular pulse crop that widely grew in Western Canadian prairie. However, the N fixation capabilities of these pea lines were not well evaluated under local environmental conditions. In this study, 2 supernodulating mutants Frisson P64 Sym29, Frisson P88 Sym28 along with their wild parent Frisson, 1 hypernodulating mutant Rondo-nod3 (fix+) along with its wild parent Rondo, 1 non-nodulating mutant Frisson P56 (nod-) and 2 commercial pea cultivar CDC Meadow and CDC Dakota which are widely planted in Western Canada were selected in order to evaluate the capabilities of their BNF, biomass, and yield production in symbiosis with R. leguminosarumbv. viciae, Our results showed different environmental conditions and variation of pea lines could both significantly impact days to flowering (DTF), days to podding (DTP), biomass and yield of tested pea lines (P < 0.0001), suggesting consideration of environmental factors could be important when selecting pea cultivar for local farming under different soil zones in Western Canada. Significant interaction effects between environmental conditions and pea lines were found on pea N fixation as well (P = 0.001), suggesting changes in N fixation capability of the same pea cultivar when grown under different environmental conditions. Our results provide useful information for farming and better opportunity for selection of pea cultivars with higher N-fixing capacity during breeding programs in Western Canada. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Canadian%20prairie" title="Canadian prairie">Canadian prairie</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20condition" title=" environmental condition"> environmental condition</a>, <a href="https://publications.waset.org/abstracts/search?q=N%20fixation" title=" N fixation"> N fixation</a>, <a href="https://publications.waset.org/abstracts/search?q=pea%20cultivar" title=" pea cultivar"> pea cultivar</a> </p> <a href="https://publications.waset.org/abstracts/48483/evaluation-of-nitrogen-fixation-capabilities-of-selected-pea-lines-grown-under-different-environmental-conditions-in-canadian-prairie" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48483.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">344</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> The Influence of Surface Roughness on the Flow Fields Generated by an Oscillating Cantilever</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ciaran%20Conway">Ciaran Conway</a>, <a href="https://publications.waset.org/abstracts/search?q=Nick%20Jeffers"> Nick Jeffers</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeff%20Punch"> Jeff Punch</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the current trend of miniaturisation of electronic devices, piezoelectric fans have attracted increasing interest as an alternative means of forced convection over traditional rotary solutions. Whilst there exists an abundance of research on various piezo-actuated flapping fans in the literature, the geometries of these fans all consist of a smooth rectangular cross section with thicknesses typically of the order of 100 um. The focus of these studies is primarily on variables such as frequency, amplitude, and in some cases resonance mode. As a result, the induced flow dynamics are a direct consequence of the pressure differential at the fan tip as well as the pressure-driven ‘over the top’ vortices generated at the upper and lower edges of the fan. Rough surfaces such as golf ball dimples or vortex generators on an aircraft wing have proven to be beneficial by tripping the boundary layer and energising the adjacent air flow. This paper aims to examine the influence of surface roughness on the airflow generation of a flapping fan and determine whether the induced wake can be manipulated or enhanced by energising the airflow around the fan tip. Particle Image Velocimetry (PIV) is carried out on mechanically oscillated rigid fans with various surfaces consisting of pillars, perforations and cell-like grids derived from the wing topology of natural fliers. The results of this paper may be used to inform the design of piezoelectric fans and possibly aid in understanding the complex aerodynamics inherent in flapping wing flight. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerodynamics" title="aerodynamics">aerodynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=oscillating%20cantilevers" title=" oscillating cantilevers"> oscillating cantilevers</a>, <a href="https://publications.waset.org/abstracts/search?q=PIV" title=" PIV"> PIV</a>, <a href="https://publications.waset.org/abstracts/search?q=vortices" title=" vortices"> vortices</a> </p> <a href="https://publications.waset.org/abstracts/74807/the-influence-of-surface-roughness-on-the-flow-fields-generated-by-an-oscillating-cantilever" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74807.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">217</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> Why is the Recurrence Rate of Residual or Recurrent Disease Following Endoscopic Mucosal Resection (EMR) of the Oesophageal Dysplasia’s and T1 Tumours Higher in the Greater Midlands Cancer Network?</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Harshadkumar%20Rajgor">Harshadkumar Rajgor</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeff%20Butterworth"> Jeff Butterworth</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Barretts oesophagus increases the risk of developing oesophageal adenocarcinoma. Over the last 40 years, there has been a 6 fold increase in the incidence of oesophageal adenocarcinoma in the western world and the incidence rates are increasing at a greater rate than cancers of the colon, breast and lung. Endoscopic mucosal resection (EMR) is a relatively new technique being used by 2 centres in the greater midlands cancer network. EMR can be used for curative or staging purposes, for high-grade dysplasia’s and T1 tumours of the oesophagus. EMR is also suitable for those who are deemed high risk for oesophagectomy. EMR has a recurrence rate of 21% according to the Wiesbaden data. Method: A retrospective study of prospectively collected data was carried out involving 24 patients who had EMR for curative or staging purposes. Complications of residual or recurrent disease following EMR that required further treatment were investigated. Results: In 54% of cases residual or recurrent disease was suspected. 96% of patients were given clear and concise information regarding their diagnosis of high-grade dysplasia or T1 tumours. All 24 patients consulted the same specialist healthcare team. Conclusion: EMR is a safe and effective treatment for patients who have high-grade dysplasia and T1NO tumours. In 54% of cases residual or recurrent disease was suspected. Initially, only single resections were undertaken. Multiple resections are now being carried out to reduce the risk of recurrence. Complications from EMR remain low in this series and consisted of a single episode of post procedural bleeding. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=endoscopic%20mucosal%20resection" title="endoscopic mucosal resection">endoscopic mucosal resection</a>, <a href="https://publications.waset.org/abstracts/search?q=oesophageal%20dysplasia" title=" oesophageal dysplasia"> oesophageal dysplasia</a>, <a href="https://publications.waset.org/abstracts/search?q=T1%20tumours" title=" T1 tumours"> T1 tumours</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer%20network" title=" cancer network"> cancer network</a> </p> <a href="https://publications.waset.org/abstracts/22352/why-is-the-recurrence-rate-of-residual-or-recurrent-disease-following-endoscopic-mucosal-resection-emr-of-the-oesophageal-dysplasias-and-t1-tumours-higher-in-the-greater-midlands-cancer-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22352.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">316</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">15</span> Enhancement of Light Extraction of Luminescent Coating by Nanostructuring</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aubry%20Martin">Aubry Martin</a>, <a href="https://publications.waset.org/abstracts/search?q=Nehed%20Amara"> Nehed Amara</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeff%20Nyalosaso"> Jeff Nyalosaso</a>, <a href="https://publications.waset.org/abstracts/search?q=Audrey%20Potdevin"> Audrey Potdevin</a>, <a href="https://publications.waset.org/abstracts/search?q=Fran%C3%A7Ois%20ReVeret"> FrançOis ReVeret</a>, <a href="https://publications.waset.org/abstracts/search?q=Michel%20Langlet"> Michel Langlet</a>, <a href="https://publications.waset.org/abstracts/search?q=Genevieve%20Chadeyron"> Genevieve Chadeyron</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Energy-saving lighting devices based on LightEmitting Diodes (LEDs) combine a semiconductor chip emitting in the ultraviolet or blue wavelength region to one or more phosphor(s) deposited in the form of coatings. The most common ones combine a blue LED with the yellow phosphor Y₃Al₅O₁₂:Ce³⁺ (YAG:Ce) and a red phosphor. Even if these devices are characterized by satisfying photometric parameters (Color Rendering Index, Color Temperature) and good luminous efficiencies, further improvements can be carried out to enhance light extraction efficiency (increase in phosphor forward emission). One of the possible strategies is to pattern the phosphor coatings. Here, we have worked on different ways to nanostructure the coating surface. On the one hand, we used the colloidal lithography combined with the Langmuir-Blodgett technique to directly pattern the surface of YAG:Tb³⁺ sol-gel derived coatings, YAG:Tb³⁺ being used as phosphor model. On the other hand, we achieved composite architectures combining YAG:Ce coatings and ZnO nanowires. Structural, morphological and optical properties of both systems have been studied and compared to flat YAG coatings. In both cases, nanostructuring brought a significative enhancement of photoluminescence properties under UV or blue radiations. In particular, angle-resolved photoluminescence measurements have shown that nanostructuring modifies photons path within the coatings, with a better extraction of the guided modes. These two strategies have the advantage of being versatile and applicable to any phosphor synthesizable by sol-gel technique. They then appear as promising ways to enhancement luminescence efficiencies of both phosphor coatings and the optical devices into which they are incorporated, such as LED-based lighting or safety devices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=phosphor%20coatings" title="phosphor coatings">phosphor coatings</a>, <a href="https://publications.waset.org/abstracts/search?q=nanostructuring" title=" nanostructuring"> nanostructuring</a>, <a href="https://publications.waset.org/abstracts/search?q=light%20extraction" title=" light extraction"> light extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=ZnO%20nanowires" title=" ZnO nanowires"> ZnO nanowires</a>, <a href="https://publications.waset.org/abstracts/search?q=colloidal%20lithography" title=" colloidal lithography"> colloidal lithography</a>, <a href="https://publications.waset.org/abstracts/search?q=LED%20devices" title=" LED devices"> LED devices</a> </p> <a href="https://publications.waset.org/abstracts/139533/enhancement-of-light-extraction-of-luminescent-coating-by-nanostructuring" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139533.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">176</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">14</span> Analysis and Identification of Different Factors Affecting Students’ Performance Using a Correlation-Based Network Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeff%20Chak-Fu%20Wong">Jeff Chak-Fu Wong</a>, <a href="https://publications.waset.org/abstracts/search?q=Tony%20Chun%20Yin%20Yip"> Tony Chun Yin Yip</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The transition from secondary school to university seems exciting for many first-year students but can be more challenging than expected. Enabling instructors to know students’ learning habits and styles enhances their understanding of the students’ learning backgrounds, allows teachers to provide better support for their students, and has therefore high potential to improve teaching quality and learning, especially in any mathematics-related courses. The aim of this research is to collect students’ data using online surveys, to analyze students’ factors using learning analytics and educational data mining and to discover the characteristics of the students at risk of falling behind in their studies based on students’ previous academic backgrounds and collected data. In this paper, we use correlation-based distance methods and mutual information for measuring student factor relationships. We then develop a factor network using the Minimum Spanning Tree method and consider further study for analyzing the topological properties of these networks using social network analysis tools. Under the framework of mutual information, two graph-based feature filtering methods, i.e., unsupervised and supervised infinite feature selection algorithms, are used to analyze the results for students’ data to rank and select the appropriate subsets of features and yield effective results in identifying the factors affecting students at risk of failing. This discovered knowledge may help students as well as instructors enhance educational quality by finding out possible under-performers at the beginning of the first semester and applying more special attention to them in order to help in their learning process and improve their learning outcomes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=students%27%20academic%20performance" title="students' academic performance">students' academic performance</a>, <a href="https://publications.waset.org/abstracts/search?q=correlation-based%20distance%20method" title=" correlation-based distance method"> correlation-based distance method</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20network%20analysis" title=" social network analysis"> social network analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=feature%20selection" title=" feature selection"> feature selection</a>, <a href="https://publications.waset.org/abstracts/search?q=graph-based%20feature%20filtering%20method" title=" graph-based feature filtering method"> graph-based feature filtering method</a> </p> <a href="https://publications.waset.org/abstracts/129736/analysis-and-identification-of-different-factors-affecting-students-performance-using-a-correlation-based-network-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129736.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">13</span> Modelling, Assessment, and Optimisation of Rules for Selected Umgeni Water Distribution Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khanyisile%20Mnguni">Khanyisile Mnguni</a>, <a href="https://publications.waset.org/abstracts/search?q=Muthukrishnavellaisamy%20Kumarasamy"> Muthukrishnavellaisamy Kumarasamy</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeff%20C.%20Smithers"> Jeff C.

Currently, Umgeni Water is running its distribution system based on required reservoir levels and demands and does not consider the energy cost at different times of the day, number of pump switches, and background leakages. Including these constraints can reduce operational cost, energy usage, leakages, and increase performance. Optimising pump schedules can reduce energy usage and costs while adhering to hydraulic and operational constraints. Umgeni Water has installed an online hydraulic software, WaterNet Advisor, that allows running different operational scenarios prior to implementation in order to optimise the distribution system. This study will investigate operation scenarios using optimisation techniques and WaterNet Advisor for a local water distribution system. Based on studies reported in the literature, introducing pump scheduling optimisation can reduce energy usage by approximately 30% without any change in infrastructure. Including tariff structures in an optimisation problem can reduce pumping costs by 15%, while including leakages decreases cost by 10%, and pressure drop in the system can be up to 12 m. Genetical optimisation algorithms are widely used due to their ability to solve nonlinear, non-convex, and mixed-integer problems. Other methods such as branch and bound linear programming have also been successfully used. A suitable optimisation method will be chosen based on its efficiency. The objective of the study is to reduce energy usage, operational cost, and leakages, and the feasibility of optimal solution will be checked using the Waternet Advisor. This study will provide an overview of the optimisation of hydraulic networks and progress made to date in multi-objective optimisation for a selected sub-system operated by Umgeni Water. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20usage" title="energy usage">energy usage</a>, <a href="https://publications.waset.org/abstracts/search?q=pump%20scheduling" title=" pump scheduling"> pump scheduling</a>, <a href="https://publications.waset.org/abstracts/search?q=WaterNet%20Advisor" title=" WaterNet Advisor"> WaterNet Advisor</a>, <a href="https://publications.waset.org/abstracts/search?q=leakages" title=" leakages"> leakages</a> </p> <a href="https://publications.waset.org/abstracts/152228/modelling-assessment-and-optimisation-of-rules-for-selected-umgeni-water-distribution-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152228.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">92</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> Effect of Gamma Radiation, Age of Paddy, Rice Variety and Packaging Materials on the Surface Free Fatty Acid Content of Brown Rice</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zenaida%20M.%20De%20Guzman">Zenaida M.

It is the purpose of the study to determine the effect of gamma radiation, packaging materials and age and variety of paddy on the surface free fatty acid content using two different brown rice variety, namely, RC-160 and SL-7, packed in two different packaging materials, namely, regular polyethylene bag and Super bag irradiated at 0.5 and 1.0 kGy. Brown rice was produced from 2-week old (Lot 1) and two months old paddy (Lot 2) and irradiated at the Co-60 Multipurpose Irradiation Facility, PNRI. The surface Free Fatty Acid (FFA) content was obtained following the AOCS Official Method (1982) with some modifications. The experiment was laid out using Split-Plot Randomized Control Block Design. Analysis of variance (ANOVA) showed that the effects of variety, age of paddy and interactions of both were both significant. The surface FFA of SL-7 variety was found to be significantly higher than the RC-160 variety for all radiation doses. Likewise, Lot 2 was observed to have higher surface FFA than Lot 1 regardless of packaging material and radiation dose. It was observed that the surface FFA of both varieties packed in both packaging materials increased significantly up to the 2nd or 3rd month of storage and remains the same until the 5th month. On the other hand, radiation dose did not significantly affect the surface free fatty acid content for all storage/sampling time while the packaging material significantly interacts with the type of variety and radiation dose. Gamma radiation was proven to have no significant effect on the surface free fatty acid at 0.5 and 1.0 kGy and further analyses are needed to determine the action of gamma radiation to the activity of enzyme (lipase-induced and microbial) responsible for the production of other lipolytic products and the effect of gamma radiation on the integrity of the packaging materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brown%20rice" title="brown rice">brown rice</a>, <a href="https://publications.waset.org/abstracts/search?q=free%20fatty%20acid" title=" free fatty acid"> free fatty acid</a>, <a href="https://publications.waset.org/abstracts/search?q=gamma%20radiation" title=" gamma radiation"> gamma radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=polyethylene%20bag" title=" polyethylene bag "> polyethylene bag </a> </p> <a href="https://publications.waset.org/abstracts/58253/effect-of-gamma-radiation-age-of-paddy-rice-variety-and-packaging-materials-on-the-surface-free-fatty-acid-content-of-brown-rice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58253.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">389</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> Surface Tension and Bulk Density of Ammonium Nitrate Solutions: A Molecular Dynamics Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sara%20Mosallanejad">Sara Mosallanejad</a>, <a href="https://publications.waset.org/abstracts/search?q=Bogdan%20Z.%20Dlugogorski"> Bogdan Z.

The emulsion formulation and wettability of AN prills, which affect the physical stability and detonation of ANFO, highly depend on the surface tension, density, viscosity of the used liquid. Therefore, for engineering applications of this material, the determination of density and surface tension of concentrated aqueous solutions of AN is essential. The molecular dynamics (MD) simulation method have been used to investigate the density and the surface tension of high concentrated ammonium nitrate solutions; up to its solubility limit in water. Non-polarisable models for water and ions have carried out the simulations, and the electronic continuum correction model (ECC) uses a scaling of the charges of the ions to apply the polarisation implicitly into the non-polarisable model. The results of calculated density and the surface tension of the solutions have been compared to available experimental values. Our MD simulations show that the non-polarisable model with full-charge ions overestimates the experimental results while the reduce-charge model for the ions fits very well with the experimental data. Ions in the solutions show repulsion from the interface using the non-polarisable force fields. However, when charges of the ions in the original model are scaled in line with the scaling factor of the ECC model, the ions create a double ionic layer near the interface by the migration of anions toward the interface while cations stay in the bulk of the solutions. Similar ions orientations near the interface were observed when polarisable models were used in simulations. In conclusion, applying the ECC model to the non-polarisable force field yields the density and surface tension of the AN solutions with high accuracy in comparison to the experimental measurements. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ammonium%20nitrate" title="ammonium nitrate">ammonium nitrate</a>, <a href="https://publications.waset.org/abstracts/search?q=electronic%20continuum%20correction" title=" electronic continuum correction"> electronic continuum correction</a>, <a href="https://publications.waset.org/abstracts/search?q=non-polarisable%20force%20field" title=" non-polarisable force field"> non-polarisable force field</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20tension" title=" surface tension"> surface tension</a> </p> <a href="https://publications.waset.org/abstracts/111880/surface-tension-and-bulk-density-of-ammonium-nitrate-solutions-a-molecular-dynamics-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111880.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">231</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> A Meta-Analysis of the Academic Achievement of Students With Emotional/Behavioral Disorders in Traditional Public Schools in the United States</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dana%20Page">Dana Page</a>, <a href="https://publications.waset.org/abstracts/search?q=Erica%20McClure"> Erica McClure</a>, <a href="https://publications.waset.org/abstracts/search?q=Kate%20Snider"> Kate Snider</a>, <a href="https://publications.waset.org/abstracts/search?q=Jenni%20Pollard"> Jenni Pollard</a>, <a href="https://publications.waset.org/abstracts/search?q=Tim%20Landrum"> Tim Landrum</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeff%20Valentine"> Jeff Valentine</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Extensive research has been conducted on students with emotional and behavioral disorders (EBD) and their rates of challenging behavior. In the past, however, less attention has been given to their academic achievement and outcomes. Recent research examining outcomes for students with EBD has indicated that these students receive lower grades, are less likely to pass classes, and experience higher rates of school dropout than students without disabilities and students with other high incidence disabilities. Given that between 2% and 20% of the school-age population is likely to have EBD (though many may not be identified as such), this is no small problem. Despite the need for increased examination of this population’s academic achievement, research on the actual performance of students with EBD has been minimal. This study reports the results of a meta-analysis of the limited research examining academic achievement of students with EBD, including effect sizes of assessment scores and discussion of moderators potentially impacting academic outcomes. Researchers conducted a thorough literature search to identify potentially relevant documents before screening studies for inclusion in the systematic review. Screening identified 35 studies that reported results of academic assessment scores for students with EBD. These studies were then coded to extract descriptive data across multiple domains, including placement of students, participant demographics, and academic assessment scores. Results indicated possible collinearity between EBD disability status and lower academic assessment scores, despite a lack of association between EBD eligibility and lower cognitive ability. Quantitative analysis of assessment results yielded effect sizes for academic achievement of student participants, indicating lower performance levels and potential moderators (e.g., race, socioeconomic status, and gender) impacting student academic performance. In addition to discussing results of the meta-analysis, implications and areas for future research, policy, and practice are discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=students%20with%20emotional%20behavioral%20disorders" title="students with emotional behavioral disorders">students with emotional behavioral disorders</a>, <a href="https://publications.waset.org/abstracts/search?q=academic%20achievement" title=" academic achievement"> academic achievement</a>, <a href="https://publications.waset.org/abstracts/search?q=systematic%20review" title=" systematic review"> systematic review</a>, <a href="https://publications.waset.org/abstracts/search?q=meta-analysis" title=" meta-analysis"> meta-analysis</a> </p> <a href="https://publications.waset.org/abstracts/170462/a-meta-analysis-of-the-academic-achievement-of-students-with-emotionalbehavioral-disorders-in-traditional-public-schools-in-the-united-states" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170462.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">69</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> Localized Variabilities in Traffic-related Air Pollutant Concentrations Revealed Using Compact Sensor Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eric%20A.%20Morris">Eric A.

Compact, multipollutant sensor systems are an effective solution as they enable several TRAPs to be monitored in a geospatially dense network, thus filling in the gaps between conventional monitoring stations. This work describes two applications of one such system named AirSENCE for gathering actionable air quality data relevant to smart city infrastructures. In the first application, four AirSENCE devices were co-located with traffic monitors around the perimeter of a city block in Oshawa, Ontario. This study, which coincided with the COVID-19 outbreak of 2020 and subsequent lockdown measures, demonstrated a direct relationship between decreased traffic volumes and TRAP concentrations. Conversely, road construction was observed to cause elevated TRAP levels while reducing traffic volumes, illustrating that conventional smart city sensors such as traffic counters provide inadequate data for inferring air quality conditions. The second application used two AirSENCE sensors on opposite sides of a major 2-way commuter road in Toronto. Clear correlations of TRAP concentrations with wind direction were observed, which shows that impacted areas are not necessarily static and may exhibit high day-to-day variability in air quality conditions despite consistent traffic volumes. Both of these applications provide compelling evidence favouring the inclusion of air quality sensors in current and future smart city infrastructure planning. Such sensors provide direct measurements that are useful for public health alerting as well as decision-making for projects involving traffic mitigation, heavy construction, and urban renewal efforts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=distributed%20sensor%20network" title="distributed sensor network">distributed sensor network</a>, <a href="https://publications.waset.org/abstracts/search?q=continuous%20ambient%20air%20quality%20monitoring" title=" continuous ambient air quality monitoring"> continuous ambient air quality monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=Smart%20city%20sensors" title=" Smart city sensors"> Smart city sensors</a>, <a href="https://publications.waset.org/abstracts/search?q=Internet%20of%20Things" title=" Internet of Things"> Internet of Things</a>, <a href="https://publications.waset.org/abstracts/search?q=traffic-related%20air%20pollutants" title=" traffic-related air pollutants"> traffic-related air pollutants</a> </p> <a href="https://publications.waset.org/abstracts/168969/localized-variabilities-in-traffic-related-air-pollutant-concentrations-revealed-using-compact-sensor-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168969.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">72</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> Standardizing and Achieving Protocol Objectives for ChestWall Radiotherapy Treatment Planning Process using an O-ring Linac in High-, Low- and Middle-income Countries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Milton%20Ixquiac">Milton Ixquiac</a>, <a href="https://publications.waset.org/abstracts/search?q=Erick%20Montenegro"> Erick Montenegro</a>, <a href="https://publications.waset.org/abstracts/search?q=Francisco%20Reynoso"> Francisco Reynoso</a>, <a href="https://publications.waset.org/abstracts/search?q=Matthew%20Schmidt"> Matthew Schmidt</a>, <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Mazur"> Thomas Mazur</a>, <a href="https://publications.waset.org/abstracts/search?q=Tianyu%20Zhao"> Tianyu Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiram%20Gay"> Hiram Gay</a>, <a href="https://publications.waset.org/abstracts/search?q=Geoffrey%20Hugo"> Geoffrey Hugo</a>, <a href="https://publications.waset.org/abstracts/search?q=Lauren%20Henke"> Lauren Henke</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeff%20Michael%20Michalski"> Jeff Michael Michalski</a>, <a href="https://publications.waset.org/abstracts/search?q=Angel%20Velarde"> Angel Velarde</a>, <a href="https://publications.waset.org/abstracts/search?q=Vicky%20de%20Falla"> Vicky de Falla</a>, <a href="https://publications.waset.org/abstracts/search?q=Franky%20Reyes"> Franky Reyes</a>, <a href="https://publications.waset.org/abstracts/search?q=Osmar%20Hernandez"> Osmar Hernandez</a>, <a href="https://publications.waset.org/abstracts/search?q=Edgar%20Aparicio%20Ruiz"> Edgar Aparicio Ruiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Baozhou%20Sun"> Baozhou Sun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: Radiotherapy departments in low- and middle-income countries (LMICs) like Guatemala have recently introduced intensity-modulated radiotherapy (IMRT). IMRT has become the standard of care in high-income countries (HIC) due to reduced toxicity and improved outcomes in some cancers. The purpose of this work is to show the agreement between the dosimetric results shown in the Dose Volume Histograms (DVH) to the objectives proposed in the adopted protocol. This is the initial experience with an O-ring Linac. Methods and Materials: An O-Linac Linac was installed at our clinic in Guatemala in 2019 and has been used to treat approximately 90 patients daily with IMRT. This Linac is a completely Image Guided Device since to deliver each radiotherapy session must take a Mega Voltage Cone Beam Computerized Tomography (MVCBCT). In each MVCBCT, the Linac deliver 9 UM, and they are taken into account while performing the planning. To start the standardization, the TG263 was employed in the nomenclature and adopted a hypofractionated protocol to treat ChestWall, including supraclavicular nodes achieving 40.05Gy in 15 fractions. The planning was developed using 4 semiarcs from 179-305 degrees. The planner must create optimization volumes for targets and Organs at Risk (OARs); the difficulty for the planner was the dose base due to the MVCBCT. To evaluate the planning modality, we used 30 chestwall cases. Results: The plans created manually achieve the protocol objectives. The protocol objectives are the same as the RTOG1005, and the DHV curves look clinically acceptable. Conclusions: Despite the O-ring Linac doesn´t have the capacity to obtain kv images, the cone beam CT was created using MV energy, the dose delivered by the daily image setup process still without affect the dosimetric quality of the plans, and the dose distribution is acceptable achieving the protocol objectives. <p class="card-text"><strong>Keywords:</strong> <a
