To present these two types of surfactants, sodium dodecyl sulfate and poly(ethylene glycol)-block-poly(ethylene), commonly utilized in emulsion polymerization, are chosen. By applying quartz crystal microbalance with dissipation monitoring it is found that, at low surfactant concentrations, it is easier to desorb (as measured by rate) ionic surfactants than nonionic surfactants. From molecular dynamics simulations, the effective, attractive force of these nonionic surfactants to the surface increases with the decrease of their concentration, whereas, the ionic surfactant exhibits mildly the opposite trend. The contrasting behavior of ionic and nonionic surfactants critically relies on two observations obtained from the simulations. The first is that there is a large degree of interweavement between head and tails groups in the adsorbed layer formed by the nonionic surfactant (PEO/PE systems). The second is that water molecules penetrate this layer. In the disordered layer, these nonionic surfactants generate at the surface, only oxygens of the head groups present at the interface with the water phase or oxygens next to the penetrating waters can form hydrogen bonds. Oxygens inside this layer lose this favorable energy, with a magnitude that increases with the surfactants density at the interface. This reduced stability of the surfactants diminishes their driving force for adsorption. All that is shown to be in accordance with experimental results on the dynamics of surfactants desorption. Ionic surfactants assemble into an ordered structure and the attraction to the surface was even slightly augmented at higher surfactant concentration, in agreement with the experimentally determined adsorption isotherm. The reason these two types of surfactants behave differently is because the ionic surfactant has a small head group that is strongly hydrophilic, whereas the head groups of the nonionic surfactants are large and only weakly attracted to water. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=emulsion%20polymerization%20process" title="emulsion polymerization process">emulsion polymerization process</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20dynamics%20simulations" title=" molecular dynamics simulations"> molecular dynamics simulations</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer%20surface" title=" polymer surface"> polymer surface</a>, <a href="https://publications.waset.org/abstracts/search?q=surfactants%20adsorption" title=" surfactants adsorption"> surfactants adsorption</a> </p> <a href="https://publications.waset.org/abstracts/68668/adsorption-and-desorption-behavior-of-ionic-and-nonionic-surfactants-on-polymer-surfaces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68668.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">345</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">102</span> Transformations between Bivariate Polynomial Bases</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dimitris%20Varsamis">Dimitris Varsamis</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicholas%20Karampetakis"> Nicholas Karampetakis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is well known that any interpolating polynomial P(x,y) on the vector space Pn,m of two-variable polynomials with degree less than n in terms of x and less than m in terms of y has various representations that depends on the basis of Pn,m that we select i.e. monomial, Newton and Lagrange basis etc. The aim of this paper is twofold: a) to present transformations between the coordinates of the polynomial P(x,y) in the aforementioned basis and b) to present transformations between these bases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bivariate%20interpolation%20polynomial" title="bivariate interpolation polynomial">bivariate interpolation polynomial</a>, <a href="https://publications.waset.org/abstracts/search?q=polynomial%20basis" title=" polynomial basis"> polynomial basis</a>, <a href="https://publications.waset.org/abstracts/search?q=transformations" title=" transformations"> transformations</a>, <a href="https://publications.waset.org/abstracts/search?q=interpolating%20polynomial" title=" interpolating polynomial"> interpolating polynomial</a> </p> <a href="https://publications.waset.org/abstracts/14542/transformations-between-bivariate-polynomial-bases" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14542.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">405</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">101</span> Radio Frequency Identification Chips in Colour Preference Tracking</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Ballard">A. Ballard </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The ability to track goods and products en route in the delivery system, in the warehouse, and on the top floor is a huge advantage to shippers and retailers. Recently the emergence of radio frequency identification (RFID) technology has enabled this better than ever before. However, a significant problem exists in that RFID technology depends on the quality of the information stored for each tagged product. Because of the profusion of names for colours, it is very difficult to ascertain that stored values are recognised by all users who view the product visually. This paper reports the findings of a study in which 50 consumers and 50 logistics workers were shown colour swatches and asked to choose the name of the colour from a multiple choice list. They were then asked to match consumer products, including toasters, jumpers, and toothbrushes, with the identifying inventory information available for each one. The findings show that the ability to match colours was significantly stronger with the color swatches than with the consumer products and that while logistics professionals made more frequent correct identification than the consumers, their results were still unsatisfactorily low. Based on these findings, a proposed universal model of colour identification numbers has been developed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=consumer%20preferences" title="consumer preferences">consumer preferences</a>, <a href="https://publications.waset.org/abstracts/search?q=supply%20chain%20logistics" title=" supply chain logistics"> supply chain logistics</a>, <a href="https://publications.waset.org/abstracts/search?q=radio%20frequency%20identification" title=" radio frequency identification"> radio frequency identification</a>, <a href="https://publications.waset.org/abstracts/search?q=RFID" title=" RFID"> RFID</a>, <a href="https://publications.waset.org/abstracts/search?q=colour%20preference" title=" colour preference"> colour preference</a> </p> <a href="https://publications.waset.org/abstracts/126493/radio-frequency-identification-chips-in-colour-preference-tracking" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/126493.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">121</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">100</span> Intertextuality as a Dialogue Between Postmodern Writer J.

The aim of the paper is to show how intertextuality might serve as a dialogue between two authors (J. Fowles and J. Donne) disguised in the dialogue of two protagonists of the novel : Conchis and Nicholas. Contrastive viewpoints concerning man's isolation, loneliness are stated in the dialogue.

The last major review of the literature was published over a decade ago in 2002. It would seem timely then to take stock of the literature and consider what we have learned since then. In so doing, our aim is to derive an empirically-based framework for understanding the effects of upward influence tactics to underpin future research in the field. Many factors are identified as having a major effect on upward influence processes including goals of influence, culture, gender, leadership style and the outcome of influence. A key conclusion from our review is that although upward influence tactics can result in positive outcomes for followers, the results from many studies are more often than inconclusive. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=upward%20influence%20tactics" title="upward influence tactics">upward influence tactics</a>, <a href="https://publications.waset.org/abstracts/search?q=influence%20tactics" title=" influence tactics"> influence tactics</a>, <a href="https://publications.waset.org/abstracts/search?q=influence%20strategies" title=" influence strategies"> influence strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=followership" title=" followership"> followership</a> </p> <a href="https://publications.waset.org/abstracts/15410/follower-upward-influence-tactics-a-review-of-quantitative-studies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15410.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">387</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">98</span> Biopolitics and Race in the Age of a Global Pandemic: Interactions and Transformations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aistis%20ZekevicIus">Aistis ZekevicIus</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Biopolitical theory, which was first developed by Michel Foucault, takes into consideration the administration of life by implying a style of government based on the regulation of populations as its subject. The intensification of the #BlackLivesMatter movement and popular outcries against racial discrimination in the US health system have prompted us to reconsider the relationship between biopolitics and race in the face of the COVID-19 pandemic. Based on works by Foucault, Achille Mbembe and Nicholas Mirzoeff that transcend the boundaries of poststructuralism, critical theory and postcolonial studies, the paper suggests that the global pandemic has highlighted new aspects of the interplay between biopower and race by encouraging the search for scapegoats, deepening the structural racial inequality, and thus producing necropolitical regimes of exclusion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biopolitics" title="biopolitics">biopolitics</a>, <a href="https://publications.waset.org/abstracts/search?q=biopower" title=" biopower"> biopower</a>, <a href="https://publications.waset.org/abstracts/search?q=necropolitics" title=" necropolitics"> necropolitics</a>, <a href="https://publications.waset.org/abstracts/search?q=pandemic" title=" pandemic"> pandemic</a>, <a href="https://publications.waset.org/abstracts/search?q=race" title=" race"> race</a> </p> <a href="https://publications.waset.org/abstracts/130189/biopolitics-and-race-in-the-age-of-a-global-pandemic-interactions-and-transformations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130189.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">261</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">97</span> Investigation of the Effects of Sampling Frequency on the THD of 3-Phase Inverters Using Space Vector Modulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khattab%20Al%20Qaisi">Khattab Al Qaisi</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicholas%20Bowring"> Nicholas Bowring</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the simulation results of the effects of sampling frequency on the total harmonic distortion (THD) of three-phase inverters using the space vector pulse width modulation (SVPWM) and space vector control (SVC) algorithms.

Storytelling is an age-old method of teaching that allows learners to remember important details while listening or sharing a narrative. In the modern world, digital storytelling through the use of technological tools such as podcasts and videos allow students to safely interact with each other to build skills in a fun and engaging way that also works as a confidence booster. Specifically using a constructionist approach to learning, digital storytelling allows ELL students to grow and build new and prior knowledge by creating stories via these technological means. Research herein suggests, through the use of case studies and mixed methodologies, that digital storytelling mainly yields positive results for effective learning in an ELL classroom setting. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20storytelling" title="digital storytelling">digital storytelling</a>, <a href="https://publications.waset.org/abstracts/search?q=ELL" title=" ELL"> ELL</a>, <a href="https://publications.waset.org/abstracts/search?q=narrative" title=" narrative"> narrative</a>, <a href="https://publications.waset.org/abstracts/search?q=podcast" title=" podcast"> podcast</a> </p> <a href="https://publications.waset.org/abstracts/126996/digital-storytelling-in-the-ell-classroom-a-literature-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/126996.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">138</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">95</span> High-pressure Crystallographic Characterization of f-block Element Complexes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nicholas%20B.%20Beck">Nicholas B.

Consistency of attitudes, and factors predicting change over time, are assessed. The consistency of responses has methodological implications for data collection, specifically how often such questions ought to be asked of a population. When change in attitude is observed, this study assesses the extent to which individual demographic characteristics, personality traits, and broader societal events predict change. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attitudes" title="attitudes">attitudes</a>, <a href="https://publications.waset.org/abstracts/search?q=longitudinal%20survey%20analysis" title=" longitudinal survey analysis"> longitudinal survey analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=personality" title=" personality"> personality</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20values" title=" social values"> social values</a> </p> <a href="https://publications.waset.org/abstracts/115698/modelling-consistency-and-change-of-social-attitudes-in-7-years-of-longitudinal-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/115698.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">136</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">93</span> Updating Stochastic Hosting Capacity Algorithm for Voltage Optimization Programs and Interconnect Standards</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nicholas%20Burica">Nicholas Burica</a>, <a href="https://publications.waset.org/abstracts/search?q=Nina%20Selak"> Nina Selak </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The ADHCAT (Automated Distribution Hosting Capacity Assessment Tool) was designed to run Hosting Capacity Analysis on the ComEd system via a stochastic DER (Distributed Energy Resource) placement on multiple power flow simulations against a set of violation criteria.

This paper proposes a standard methodology for the geometry simplification of rotating machines, such as electrical generators and electrical motors (both air and liquid-cooled). These machines are extensively deployed throughout the aerospace and automotive industries, where optimization of weight, volume, and performance is paramount -especially given the current global transition to renewable energy sources and vehicle hybridization and electrification. Conjugate heat transfer analysis is an essential step in optimizing their complex design.

The speaker verification framework included the MFCCs features and the GMM modeling and classification method. The speaker verification experiments within homogeneous environments showed 5.1% increase of the EER within the clinically depressed environment when compared to the non-depressed environment. It indicated that the clinical depression increases the intra-speaker variability and makes the speaker verification task more challenging. Experiments with mixed environments indicated that the increase of the percentage of the depressed individuals within a mixed environment increases the speaker verification equal error rates. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=speaker%20verification" title="speaker verification">speaker verification</a>, <a href="https://publications.waset.org/abstracts/search?q=GMM" title=" GMM"> GMM</a>, <a href="https://publications.waset.org/abstracts/search?q=EM" title=" EM"> EM</a>, <a href="https://publications.waset.org/abstracts/search?q=clinical%20environment" title=" clinical environment"> clinical environment</a>, <a href="https://publications.waset.org/abstracts/search?q=clinical%20depression" title=" clinical depression"> clinical depression</a> </p> <a href="https://publications.waset.org/abstracts/39436/effect-of-clinical-depression-on-automatic-speaker-verification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39436.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">375</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">89</span> An Empirical Investigation of Big Data Analytics: The Financial Performance of Users versus Vendors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Evisa%20Mitrou">Evisa Mitrou</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicholas%20Tsitsianis"> Nicholas Tsitsianis</a>, <a href="https://publications.waset.org/abstracts/search?q=Supriya%20Shinde"> Supriya Shinde</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the age of digitisation and globalisation, businesses have shifted online and are investing in big data analytics (BDA) to respond to changing market conditions and sustain their performance.

We distinguish between the five BDA-technologies (big-data-as-a-service (BDaaS), descriptive, diagnostic, predictive, and prescriptive analytics) and discuss them individually. Further, we use four perspectives (internal business process, learning and growth, customer, and finance) and discuss the significance of how each of the five BDA-technologies affects the performance measures of these four perspectives. We also present the analysis of employee engagement, average turnover, average net income, and average net assets for BDA-clients and BDA-vendors.

The computation of the Kalman filter gain requires the inversion of an m x m matrix in every iteration. In this paper, a variation of the Kalman filter eliminating the Kalman filter gain is proposed. In the time varying case, the elimination of the Kalman filter gain requires the inversion of an n x n matrix and the inversion of an m x m matrix in every iteration. In the time invariant case, the elimination of the Kalman filter gain requires the inversion of an n x n matrix in every iteration. The proposed Kalman filter gain elimination algorithm may be faster than the conventional Kalman filter, depending on the model dimensions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=discrete%20time" title="discrete time">discrete time</a>, <a href="https://publications.waset.org/abstracts/search?q=estimation" title=" estimation"> estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=Kalman%20filter" title=" Kalman filter"> Kalman filter</a>, <a href="https://publications.waset.org/abstracts/search?q=Kalman%20filter%20gain" title=" Kalman filter gain"> Kalman filter gain</a> </p> <a href="https://publications.waset.org/abstracts/123040/kalman-filter-gain-elimination-in-linear-estimation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123040.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">197</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> Iran’s Dual Geopolitical Approach towards African States</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dragos%20Ardeleanu">Dragos Ardeleanu</a>, <a href="https://publications.waset.org/abstracts/search?q=Silviu-Valentin%20Petre"> Silviu-Valentin Petre</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Written to satisfy the needs of Western powers, classical geopolitics bore the stint of Eurocentrism. Both Mackinder’s heartland and Nicholas Spykman’s rimland were intellectual creations set for the purpose of the Anglophone nations dealing with Eurasia. However, while today’s world is moving towards multipolarity, other emerging regional actors are following their own interests using a different geospatial map. Such is the case of Iran which has developed an engagement pattern in Africa, directed mostly towards costal states, in order to break the rimland grip of Arab states and also the international pressure established against Tehran’s nascent nuclear program. Capitalizing on literature review and analysing statements from key public figures, our paper argues that Iranian African geopolitics displays a dual message: on the one hand, it uses tiers-mondiste rhetoric to garner the support of different coastal African states and, on the other hand, it employs Shiism to gain a foothold in strategic parts of the black continent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=African%20geopolitics" title="African geopolitics">African geopolitics</a>, <a href="https://publications.waset.org/abstracts/search?q=Iran" title=" Iran"> Iran</a>, <a href="https://publications.waset.org/abstracts/search?q=Shiism" title=" Shiism"> Shiism</a>, <a href="https://publications.waset.org/abstracts/search?q=tiers-mondisme" title=" tiers-mondisme"> tiers-mondisme</a> </p> <a href="https://publications.waset.org/abstracts/90811/irans-dual-geopolitical-approach-towards-african-states" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90811.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">218</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> Rhythmic Prioritisation as a Means of Compositional Organisation: Analysing Meshuggah’s “do Not Look Down”</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nicholas%20Freer">Nicholas Freer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rhythmic complexity in progressive metal is a developing area of analysis, particularly the interpretation of hyper-metric time spans as hierarchically significant rhythmic units of compositional organisation (Pieslak 2007, Charupakorn 2012, Capuzzo 2018, Calder 2018, Lucas 2018, Hannan 2020). This paper adds to this developing area by considering the relationships between the concepts of tactus, metric imposition, polymeter and rhythmic parallax in the Meshuggah composition “Do Not Look Down”. By considering an architectonic rhythmic framework within “Do Not Look Down” as the controlling organisation mechanism, an exploration of the interaction between distinct rhythmic layers and the composition’s formal segmentation and harmony (as riffs), reveals a pervasive structural misalignment between these elements. By exhibiting how Meshuggah’s manipulations of rhythmic complexities deliberately blur structural boundaries, creating misalignments in a flat approach to temporal partitioning (Nieto 2014), rhythmic characteristics of Meshuggah and the genre of Djent are exposed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hypermeter" title="hypermeter">hypermeter</a>, <a href="https://publications.waset.org/abstracts/search?q=rhythmic%20parallax" title=" rhythmic parallax"> rhythmic parallax</a>, <a href="https://publications.waset.org/abstracts/search?q=meshuggah" title=" meshuggah"> meshuggah</a>, <a href="https://publications.waset.org/abstracts/search?q=temporal%20partitioning" title=" temporal partitioning"> temporal partitioning</a> </p> <a href="https://publications.waset.org/abstracts/166951/rhythmic-prioritisation-as-a-means-of-compositional-organisation-analysing-meshuggahs-do-not-look-down" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166951.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">78</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">85</span> Distance Education: Using a Digital Platform to Improve Struggling University Students' Mathematical Skills</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Robert%20Vanderburg">Robert Vanderburg</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicholas%20Gibson"> Nicholas Gibson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objectives: There has been an increased focus in education students’ mathematics skills in the last two years. Universities have, specifically, had problems teaching students struggling with mathematics. This paper focuses on the ability of a digital platform to significantly improve mathematics skills for struggling students. Methods: 32 students who demonstrated low scores on a mathematics test were selected to take part in a one-month tutorial program using a digital mathematics portal. Students were provided feedback for questions posted on the portal and a fortnightly tutorial session. Results: A pre-test post-test design was analyzed using a one-way analysis of variance (ANOVA). The analysis suggested that students improved skills in algebra, geometry, statistics, probability, ratios, fractions, and probability.

Our research asked adults with intellectual disability, parents and carers and disability, housing and built environment decision makers what they considered important in deciding where to live. If medical advances continue to improve the longevity of adults with intellectual disability, many of these adults will outlive their parents. With appropriate community support, and in appropriately designed neighbourhoods, many will be able to live independently. Our research suggests that the key to achieving independent living as an adult with intellectual disability is not so much about the house but the type of neighbourhood and its design.

This may be the first reported case in the literature for meningoencephalitis to occur following a Le Fort I Osteotomy. Case: A 32-year-old female was brought into the Emergency Department four days after a Le Fort I Osteotomy, with a Glasgow Coma Scale (GCS) of 8 (E3V1M4). A Computed Tomography (CT) Head showed a skull base fracture at the right sphenoid sinus. Lumbar puncture was completed, and Klebsiella oxytoca was found in the Cerebrospinal Fluid (CSF). She was treated with Meropenem, and rapidly improved thereafter. CSF rhinorrhoea was identified when she was extubated, which was successfully managed via a continuous lumbar drain.

Conclusion: The most likely aspect of the Le Fort I Osteotomy to obtain a skull base fracture is during the pterygomaxillary disjunction. Care should always be taken to avoid significant risks of skull base fractures, CSF rhinorrhoea, meningitis and encephalitis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=meningitis" title="meningitis">meningitis</a>, <a href="https://publications.waset.org/abstracts/search?q=orthognathic%20surgery" title=" orthognathic surgery"> orthognathic surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=post-operative%20complication" title=" post-operative complication"> post-operative complication</a>, <a href="https://publications.waset.org/abstracts/search?q=skull%20base" title=" skull base"> skull base</a>, <a href="https://publications.waset.org/abstracts/search?q=rhinorrhea" title=" rhinorrhea"> rhinorrhea</a> </p> <a href="https://publications.waset.org/abstracts/137431/a-case-study-of-meningoencephalitis-following-le-fort-i-osteotomy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137431.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">82</span> Experimental Investigation of Cup Anemometer under Static and Dynamic Wind Direction Changes: Evaluation of Directional Sensitivity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vaibhav%20Rana">Vaibhav Rana</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicholas%20Balaresque"> Nicholas Balaresque</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The 3-cup anemometer is the most commonly used instrument for wind speed measurement and, consequently, for the wind resource assessment. Though the cup anemometer shows accurate measurement under quasi-static conditions, there is uncertainty in the measurement when subjected to field measurement. Sensitivity to the angle of attacks with respect to horizontal plane, dynamic response, and non-linear behavior in calibration due to friction. The presented work aimed to identify the sensitivity of anemometer to non-horizontal flow. The cup anemometer was investigated under low wind speed wind tunnel, first under the static flow direction changes and second under the dynamic direction changes, at a different angle of attacks, under the similar conditions of reference wind tunnel speeds. The cup anemometer response under both conditions was evaluated and compared. The results showed the anemometer under dynamic wind direction changes is highly sensitive compared to static conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wind%20energy" title="wind energy">wind energy</a>, <a href="https://publications.waset.org/abstracts/search?q=cup%20anemometer" title=" cup anemometer"> cup anemometer</a>, <a href="https://publications.waset.org/abstracts/search?q=directional%20sensitivity" title=" directional sensitivity"> directional sensitivity</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20behavior" title=" dynamic behavior"> dynamic behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20tunnel" title=" wind tunnel"> wind tunnel</a> </p> <a href="https://publications.waset.org/abstracts/130976/experimental-investigation-of-cup-anemometer-under-static-and-dynamic-wind-direction-changes-evaluation-of-directional-sensitivity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130976.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">149</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> Machine Learning-Enabled Classification of Climbing Using Small Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nicholas%20Milburn">Nicholas Milburn</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu%20Liang"> Yu Liang</a>, <a href="https://publications.waset.org/abstracts/search?q=Dalei%20Wu"> Dalei Wu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Athlete performance scoring within the climbing do-main presents interesting challenges as the sport does not have an objective way to assign skill. Assessing skill levels within any sport is valuable as it can be used to mark progress while training, and it can help an athlete choose appropriate climbs to attempt. Machine learning-based methods are popular for complex problems like this. The dataset available was composed of dynamic force data recorded during climbing; however, this dataset came with challenges such as data scarcity, imbalance, and it was temporally heterogeneous. Investigated solutions to these challenges include data augmentation, temporal normalization, conversion of time series to the spectral domain, and cross validation strategies. The investigated solutions to the classification problem included light weight machine classifiers KNN and SVM as well as the deep learning with CNN. The best performing model had an 80% accuracy. In conclusion, there seems to be enough information within climbing force data to accurately categorize climbers by skill. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=classification" title="classification">classification</a>, <a href="https://publications.waset.org/abstracts/search?q=climbing" title="climbing">climbing</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20imbalance" title="data imbalance">data imbalance</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20scarcity" title="data scarcity">data scarcity</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=time%20sequence" title="time sequence">time sequence</a> </p> <a href="https://publications.waset.org/abstracts/146877/machine-learning-enabled-classification-of-climbing-using-small-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146877.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">144</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">80</span> Detroit Latinx Adolescents Depend on Relationships, Recreation, and Internal Homeostasis to Live their Healthiest Lives</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jenny%20Clift">Jenny Clift</a>, <a href="https://publications.waset.org/abstracts/search?q=Rebeccah%20Sokol"> Rebeccah Sokol</a>, <a href="https://publications.waset.org/abstracts/search?q=LaTricia%20Mitchell"> LaTricia Mitchell</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicholas%20Alexander"> Nicholas Alexander</a>, <a href="https://publications.waset.org/abstracts/search?q=Karissa%20Rusnick"> Karissa Rusnick</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aims: This study sought to identify prevalent promotive factors supporting urban adolescent health and wellbeing, per adolescent and caregiver reports.

Nevertheless, the Eastern policies of Russia were in contradiction with the interests of Great Britain which was the great power of the era. Yet, it did hesitate to be confronted with Russian on its route to India, so the Ottoman territorial integrity was defended. In that period, Tzar Nicholas II, to begin with, tried to eliminate a probable opposition coming from the British side, and then tried its chance to build up cooperation with Britain on the territories of the sick man. As a more positive relation was being observed between these two states before the Crimean War, Great Britain initially had adopted a neutral policy. However, in the end, Britain entered the war against Russia due to the efforts of the opposing side in the British Parliament and the rising pressure of the public opinion. The article aims to examine the role of British public opinion in the process of Great Britain’s Involvement in this war. Also, the article will try to find an answer to the following question: to what extent did the public opinion become effective on the foreign policy-making of Great Britain before the war? <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=British%20press" title="British press">British press</a>, <a href="https://publications.waset.org/abstracts/search?q=Crimean%20war" title=" Crimean war"> Crimean war</a>, <a href="https://publications.waset.org/abstracts/search?q=Great%20Britain" title=" Great Britain"> Great Britain</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20opinion" title=" public opinion"> public opinion</a> </p> <a href="https://publications.waset.org/abstracts/95464/the-role-of-british-public-opinion-in-the-process-of-the-great-britains-involvement-in-the-crimean-war" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95464.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">78</span> Evaluation of Fuel Properties of Six Tropical Hardwood Timber Species for Briquettes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stephen%20J.%20Mitchual">Stephen J.

Properties studied include the species density, gross calorific value, volatile matter, ash, organic carbon, N, H, S, Cu, Pb, As and Cd content. Fuel properties were determined using standard laboratory methods. The result indicates that the Gross Calorific Value (GCV) of the species ranged from 20.16 to 22.22 MJ/kg and they slightly varied from each other. Additionally, the GCV of the biomass materials were higher than that of other biomass materials like; wheat straw, rice straw, maize straw and sugar cane. The ash and volatile matter content varied from 0.6075 to 5.0407%, and 75.23% to 83.70% respectively. The overall rating of the properties of the six biomass materials suggest that Piptadenia africana has the best fuel property to be used as briquettes and Aningeria robusta the worse. This study therefore suggests that a holistic assessment of a biomass material needs to be done before selecting it for fuel purpose. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ash%20content" title="ash content">ash content</a>, <a href="https://publications.waset.org/abstracts/search?q=briquette" title=" briquette"> briquette</a>, <a href="https://publications.waset.org/abstracts/search?q=calorific%20value" title=" calorific value"> calorific value</a>, <a href="https://publications.waset.org/abstracts/search?q=elemental%20composition" title=" elemental composition"> elemental composition</a>, <a href="https://publications.waset.org/abstracts/search?q=species" title=" species"> species</a>, <a href="https://publications.waset.org/abstracts/search?q=volatile%20matter" title=" volatile matter"> volatile matter</a> </p> <a href="https://publications.waset.org/abstracts/4930/evaluation-of-fuel-properties-of-six-tropical-hardwood-timber-species-for-briquettes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4930.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">423</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">77</span> Visualization of Flow Behaviour in Micro-Cavities during Micro Injection Moulding</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reza%20Gheisari">Reza Gheisari</a>, <a href="https://publications.waset.org/abstracts/search?q=Paulo%20J.%20Bartolo"> Paulo J.

Polymer materials present suitable physical and chemical properties combined with low-cost mass production. Hence, micro-cantilevers made of polymers indicate much more biocompatibility and adaptability of rapid prototyping along with mechanical properties. This research studies the effects of three process and one size factors on the filling behaviour in micro cavity, and the role of each in the replication of micro parts using different polymer materials i.e. polypropylene (PP) SABIC 56M10 and acrylonitrile butadiene styrene (ABS) Magnum 8434. In particular, the following factors are considered: barrel temperature, mould temperature, injection speed and the thickness of micro features. The study revealed that the barrel temperature and the injection speed are the key factors affecting the flow length of micro features replicated in PP and ABS. For both materials, an increase of feature sizes improves the melt flow. However, the melt fill of micro features does not increase linearly with the increase of their thickness. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flow%20length" title="flow length">flow length</a>, <a href="https://publications.waset.org/abstracts/search?q=micro%20cantilevers" title=" micro cantilevers"> micro cantilevers</a>, <a href="https://publications.waset.org/abstracts/search?q=micro%20injection%20moulding" title=" micro injection moulding"> micro injection moulding</a>, <a href="https://publications.waset.org/abstracts/search?q=microfabrication" title=" microfabrication"> microfabrication</a> </p> <a href="https://publications.waset.org/abstracts/35671/visualization-of-flow-behaviour-in-micro-cavities-during-micro-injection-moulding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35671.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">398</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">76</span> Validation Pulmonary Embolus Severity Index Score Early Mortality Rate at 1, 3, 7 Days in Patients with a Diagnosis of Pulmonary Embolism</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nicholas%20Marinus%20Batt">Nicholas Marinus Batt</a>, <a href="https://publications.waset.org/abstracts/search?q=Angus%20Radford"> Angus Radford</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Saraya"> Khaled Saraya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pulmonary Embolus Severity Index (PESI) score is a well-validated decision-making score grading mortality rates (MR) in patients with a suspected or confirmed diagnosis of pulmonary embolism (PE) into 5 classes.

Design: The study employs a case study observational research (CSOR) approach, and data were collected using first-hand observations and interviews. Findings: A model of leadership behaviour and a series of steps that leaders can take to leverage trust are presented. Leaders can have a positive impact even if the team is operating in a challenging context. Creating a positive environment brings sustainability to the team and perhaps the wider organization as well.

Previous literature suggests improved CDH outcomes at high-volume regional referral centers compared to low-volume centers. The purpose of this study was to examine CDH outcomes at Kentucky Children’s Hospital (KCH), a low-volume center, compared to the Congenital Diaphragmatic Hernia Study Group (CDHSG). Methods: A retrospective chart review was performed at KCH from 2007-2019 for neonates with CDH, and then subdivided into two cohorts: those requiring ECMO therapy and those not requiring ECMO therapy. Basic demographic data and measures of mortality and morbidity including ventilator days and length of stay were compared to the CDHSG. Measures of morbidity for the ECMO cohort including duration of ECMO, clinical bleeding, intracranial hemorrhage, sepsis, need for continuous renal replacement therapy (CRRT), need for sildenafil at discharge, timing of surgical repair, and total ventilator days were collected. Statistical analysis was performed using IBM SPSS Statistics version 28. One-sample t-tests and one-sample Wilcoxon Signed Rank test were utilized as appropriate.Results: There were a total of 27 neonatal patients with CDH at KCH from 2007-2019; 9 of the 27 required ECMO therapy. The birth weight and gestational age were similar between KCH and the CDHSG (2.99 kg vs 2.92 kg, p =0.655; 37.0 weeks vs 37.4 weeks, p =0.51). About half of the patients were inborn in both cohorts (52% vs 56%, p =0.676). KCH cohort had significantly more Caucasian patients (96% vs 55%, p=<0.001). Unadjusted mortality was similar in both groups (KCH 70% vs CDHSG 72%, p =0.857). Using ECMO utilization (KCH 78% vs CDHSG 52%, p =0.118) and need for surgical repair (KCH 95% vs CDHSG 85%, p =0.060) as proxy for severity, both groups’ mortality were comparable. No significant difference was noted for pulmonary outcomes such as average ventilator days (KCH 43.2 vs. CDHSG 17.3, p =0.078) and home oxygen dependency (KCH 44% vs. CDHSG 24%, p =0.108). Average length of hospital stay for patients treated at KCH was similar to CDHSG (64.4 vs 49.2, p=1.000). Conclusion: Our study demonstrates that outcome in CDH patients is independent of center’s case volume status. Management of CDH with a standardized approach in a low-volume center can yield similar outcomes. This data supports the treatment of patients with CDH at low-volume centers as opposed to transferring to higher-volume centers. <p class="card-text"><strong>Keywords:</strong> <a
