Although the level of under-five mortality has been declining, it is still unacceptably high. The primary aim of this paper is to establish and analyse the levels and trends of under-five mortality for the periods 1998, 2003 and 2012 in South Africa. Methods: The data used for analysis came from the 1998 SADHS, the 2003 SADHS and the 2012 SABSSM which collected information on the survival status of children. The Kaplan-Meier estimate of the survival function method was used to determine the probabilities of failure (death) from birth up to 59 months. Results and Conclusion: The overall U5MR declined by 28.2% from 53.1 in 1998 to 38.1 in 2012. The U5MR of male children declined from 59.2 in 1998 to 46.2 in 2003 and dropped further to 41.4 in 2012. The U5MR of children of mothers aged 40 years and older increased from 64.0 in 1998 to 89.0 in 2003 and rose further to 129.9 in 2012. The U5MR of children of mothers with education level of 12 years or more increased from 32.2 in 1998 to 35.2 in 2003 and declined substantially to 17.5 in 2012. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=demographic%20and%20health%20survey" title="demographic and health survey">demographic and health survey</a>, <a href="https://publications.waset.org/abstracts/search?q=Kaplan-Meier" title=" Kaplan-Meier"> Kaplan-Meier</a>, <a href="https://publications.waset.org/abstracts/search?q=levels%20and%20trends" title=" levels and trends"> levels and trends</a>, <a href="https://publications.waset.org/abstracts/search?q=under-five%20mortality" title=" under-five mortality"> under-five mortality</a> </p> <a href="https://publications.waset.org/abstracts/120546/levels-and-trends-of-under-five-mortality-in-south-africa-from-1998-to-2012" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120546.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">142</span> MAGE-A3 and PRAME Gene Expression and EGFR Mutation Status in Non-Small-Cell Lung Cancer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Renata%20Checiches">Renata Checiches</a>, <a href="https://publications.waset.org/abstracts/search?q=Thierry%20Coche"> Thierry Coche</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicolas%20F.%20Delahaye"> Nicolas F.

EGFR, KRAS and BRAF mutation status was determined in a subset to investigate associations with MAGE A3 and PRAME expression. Methods: We conducted a single-centre, uncontrolled, retrospective study of 1260 tissue-bank samples from stage IA-III resected NSCLC. The prognostic value of antigen expression (qRT-PCR) was determined by hazard-ratio and Kaplan-Meier curves. Results: Thirty-seven percent (314/844) of tumours expressed MAGE-A3, 66% (723/1092) expressed PRAME and 31% (239/839) expressed both. Respective frequencies in squamous-cell tumours and adenocarcinomas were 43%/30% for MAGE A3 and 80%/44% for PRAME. No correlation with stage, tumour size or patient age was found. Overall, no prognostic value was identified for either antigen. A trend to poorer overall survival was associated with MAGE-A3 in stage IIIB and with PRAME in stage IB. EGFR and KRAS mutations were found in 10.1% (28/311) and 33.8% (97/311) of tumours, respectively. EGFR (but not KRAS) mutation status was negatively associated with PRAME expression. Conclusion: No clear prognostic value for either PRAME or MAGE A3 was observed in the overall population, although some observed trends may warrant further investigation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MAGE%20A3" title="MAGE A3">MAGE A3</a>, <a href="https://publications.waset.org/abstracts/search?q=PRAME" title=" PRAME"> PRAME</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer-testis%20gene" title=" cancer-testis gene"> cancer-testis gene</a>, <a href="https://publications.waset.org/abstracts/search?q=NSCLC" title=" NSCLC"> NSCLC</a>, <a href="https://publications.waset.org/abstracts/search?q=survival" title=" survival"> survival</a>, <a href="https://publications.waset.org/abstracts/search?q=EGFR" title=" EGFR"> EGFR</a> </p> <a href="https://publications.waset.org/abstracts/54549/mage-a3-and-prame-gene-expression-and-egfr-mutation-status-in-non-small-cell-lung-cancer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54549.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">141</span> Cerebral Pulsatility Mediates the Link Between Physical Activity and Executive Functions in Older Adults with Cardiovascular Risk Factors: A Longitudinal NIRS Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hanieh%20Mohammadi">Hanieh Mohammadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarah%20Fraser"> Sarah Fraser</a>, <a href="https://publications.waset.org/abstracts/search?q=Anil%20Nigam"> Anil Nigam</a>, <a href="https://publications.waset.org/abstracts/search?q=Frederic%20%20Lesage"> Frederic Lesage</a>, <a href="https://publications.waset.org/abstracts/search?q=Louis%20Bherer"> Louis Bherer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A chronically higher cerebral pulsatility is thought to damage cerebral microcirculation, leading to cognitive decline in older adults. Although it is widely known that regular physical activity is linked to improvement in some cognitive domains, including executive functions, the mediating role of cerebral pulsatility on this link remains to be elucidated. This study assessed the impact of 6 months of regular physical activity upon changes in an optical index of cerebral pulsatility and the role of physical activity for the improvement of executive functions. 27 older adults (aged 57-79, 66.7% women) with cardiovascular risk factors (CVRF) were enrolled in the study. The participants completed the behavioral Stroop test, which was extracted from the Delis-Kaplan executive functions system battery at baseline (T0) and after 6 months (T6) of physical activity. Near-infrared spectroscopy (NIRS) was applied for an innovative approach to indexing cerebral pulsatility in the brain microcirculation at T0 and T6. The participants were at standing rest while a NIRS device recorded hemodynamics data from frontal and motor cortex subregions at T0 and T6. The cerebral pulsatility index of interest was cerebral pulse amplitude, which was extracted from the pulsatile component of NIRS data. Our data indicated that 6 months of physical activity was associated with a reduction in the response time for the executive functions, including inhibition (T0: 56.33± 18.2 to T6: 53.33± 15.7,p= 0.038)and Switching(T0: 63.05± 5.68 to T6: 57.96 ±7.19,p< 0.001) conditions of the Stroop test. Also, physical activity was associated with a reduction in cerebral pulse amplitude (T0: 0.62± 0.05 to T6: 0.55± 0.08, p < 0.001). Notably, cerebral pulse amplitude was a significant mediator of the link between physical activity and response to the Stroop test for both inhibition (β=0.33 (0.61,0.23),p< 0.05)and switching (β=0.42 (0.69,0.11),p <0.01) conditions. This study suggests that regular physical activity may support cognitive functions through the improvement of cerebral pulsatility in older adults with CVRF. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=near-infrared%20spectroscopy" title="near-infrared spectroscopy">near-infrared spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=cerebral%20pulsatility" title=" cerebral pulsatility"> cerebral pulsatility</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20activity" title=" physical activity"> physical activity</a>, <a href="https://publications.waset.org/abstracts/search?q=cardiovascular%20risk%20factors" title=" cardiovascular risk factors"> cardiovascular risk factors</a>, <a href="https://publications.waset.org/abstracts/search?q=executive%20functions" title=" executive functions"> executive functions</a> </p> <a href="https://publications.waset.org/abstracts/138094/cerebral-pulsatility-mediates-the-link-between-physical-activity-and-executive-functions-in-older-adults-with-cardiovascular-risk-factors-a-longitudinal-nirs-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138094.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">195</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">140</span> Early Versus Delayed Antiretroviral Therapy in HIV‐positive People with Tuberculosis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohhamed%20El%20Habib%20Labdouni">Mohhamed El Habib Labdouni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Co-infection with VIH and tuberculosis poses one of the major ongoing challenges for global TB and AIDS prevention and control. The objective of this study is to raise the issue of the resurgence of TB, in People living with VIH supported in a referent center in western Algeria. Its epidemiological, clinical, biological and radiological new trends, and to compare the mortality rate between early and delayed ART. Methods: It was a prospective study, during 36 months from the 01st/01/2012 to 31st/12/2014, by identifying and analyzing cases of TB-VIH co-infection. Our population was devised in two groups/ early ART and delayed ART. The primary and secondary endpoints were analyzed with Kaplan-Meier curves and log-rank test the period of follow up, which was fixed at 300 weeks. Results: Sixty cases of co-infection TB -VIH were enrolled in our study: 78.3% had pulmonary tuberculosis associated with extra-pulmonary, 13.3% had only pulmonary tuberculosis and 08.3% presented strictly extra-pulmonary TB. The clinical particularity of this co-infection is the frequency of serious localization such us: pleural 23.3%, peritoneal 31.7%, and meningeal suffusion 13.3%.y-.biologicaly we notice the predominance both of pancytopenia and leucoanemia, hyponatremia in 38,6% and hypokalemia in 19,3%. By analyzing Kaplan-Meier survival curves, we notice that early ART initiation is associated with a significant reduction of all-cause mortality (p = 0,000), and we have identified several prognostic factors such as hypokalemia hyponatremia, leukocytosis thrombopenemia leucothrombopenia (p = 0,005). Conclusion: Our study confirms most of the results reported in the literature. Early ART initiation reduces the rate of all-cause mortality, despite the probability of the occurrence of TB-IRIS. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=TB-HIV%20co-infection" title="TB-HIV co-infection">TB-HIV co-infection</a>, <a href="https://publications.waset.org/abstracts/search?q=early%20ART" title=" early ART"> early ART</a>, <a href="https://publications.waset.org/abstracts/search?q=hyponatremia" title=" hyponatremia"> hyponatremia</a>, <a href="https://publications.waset.org/abstracts/search?q=extrapulmonary%20tuberculosis" title=" extrapulmonary tuberculosis"> extrapulmonary tuberculosis</a> </p> <a href="https://publications.waset.org/abstracts/142918/early-versus-delayed-antiretroviral-therapy-in-hivpositive-people-with-tuberculosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142918.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">139</span> Predictor Factors for Treatment Failure among Patients on Second Line Antiretroviral Therapy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohd.%20A.%20M.%20Rahim">Mohd.

There are many factors such as non-adherence, drug resistance as well as virological and immunological failure that lead to second line highly active antiretroviral therapy (HAART) regimen treatment failure. This study was aimed at determining predictor factors to treatment failure with second line HAART and analyzing median survival time. An observational, retrospective study was conducted in Sungai Buloh Hospital (HSB) to assess current status of HIV patients treated with second line HAART regimen. Convenience sampling was used and 104 patients were included based on the study’s inclusion and exclusion criteria. Data was collected for six months i.e. from July until December 2013. Data was then analysed using SPSS version 18. Kaplan-Meier and Cox regression analyses were used to measure median survival times and predictor factors for treatment failure. The study population consisted mainly of male subjects, aged 30-45 years, who were heterosexual, and had HIV infection for less than 6 years. The most common second line HAART regimen given was lopinavir/ritonavir (LPV/r)-based combination. Kaplan-Meier analysis showed that patients on LPV/r demonstrated longer median survival times than patients on indinavir/ritonavir (IDV/r) based combination (p<0.001). The commonest reason for a treatment to fail with second line HAART was non-adherence. Based on Cox regression analysis, other predictor factors for treatment failure with second line HAART regimen were age and mode of HIV transmission. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adherence" title="adherence">adherence</a>, <a href="https://publications.waset.org/abstracts/search?q=antiretroviral%20therapy" title=" antiretroviral therapy"> antiretroviral therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=second%20line" title=" second line"> second line</a>, <a href="https://publications.waset.org/abstracts/search?q=treatment%20failure" title=" treatment failure"> treatment failure</a> </p> <a href="https://publications.waset.org/abstracts/13817/predictor-factors-for-treatment-failure-among-patients-on-second-line-antiretroviral-therapy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13817.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">264</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">138</span> Search for EEG Correlates of Mental States Using EEG Neurofeedback Paradigm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cyril%20Kaplan">Cyril Kaplan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> 26 participants played 4 EEG neurofeedback (NF) games encouraged to find their strategies to control the specific NF parameter.

New drugs have been introduced, including the group of drugs called Angiotensin receptor Neprilysin Inhibitor (ARNI), but due to their high cost, angiotensin-converting enzymes inhibitors (ACEIs) and Angiotensin receptor blockers (ARBs) have been mostly used in Tanzania. However, according to our knowledge, the efficacy comparison of the two groups is yet to be studied in Tanzania. The aim of this study was to compare the efficacy of ACEIs and ARBs among patients with heart failure. Methodology: This was a hospital-based prospective cohort study done at Jakaya Kikwete Cardiac Institution (JKCI), Tanzania, from June to December 2020. Consecutive enrollment was done until fulfilling the inclusion criteria. Clinical details were measured at baseline. We assessed the relationship between ARBs and ACEIs users with N-terminal pro-brain natriuretic peptide (NT pro-BNP) levels at admission and at 1-month follow-up using a chi-square test. A Kaplan-Meier curve was used to estimate the survival time of the two groups. Results: 155 HF patients were enrolled, with a mean age of 48 years, whereby 52.3% were male, and their mean left ventricular ejection fraction (LVEF) was 37.3%. 52 (33.5%) heart failure patients were on ACEIs, 57 (36.8%) on ARBs, and 46 (29.7%) were neither using ACEIs nor ARBs. At least half of the patients did not receive a guideline-directed medical therapy (GDMT), with only 82 (52.9%) receiving a GDMT. A drop in NT pro-BNP levels was observed during admission and at 1-month follow-up on both groups, from 6389.2 pg/ml to 4000.1 pg/ml for ARB users and 5877.7 pg/ml to 1328.2 pg/ml for the ACEIs users. There was no statistical difference between the two groups when estimated by the Kaplan-Meier curve, though more deaths were observed in those who were neither on ACEIs nor ARBs, with a calculated P value of 0.01. Conclusion: This study demonstrates that ACEIs have more efficacy and overall better clinical outcome than ARBs, but this should be taken under the patient-based case, considering the side effects of ACEIs and patients’ adherence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=angiotensin%20converting%20enzymes%20inhibitors" title="angiotensin converting enzymes inhibitors">angiotensin converting enzymes inhibitors</a>, <a href="https://publications.waset.org/abstracts/search?q=angiotensin%20receptor%20blockers" title=" angiotensin receptor blockers"> angiotensin receptor blockers</a>, <a href="https://publications.waset.org/abstracts/search?q=guideline%20direct%20medical%20therapy" title=" guideline direct medical therapy"> guideline direct medical therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=N-terminal%20pro-brain%20natriuretic%20peptide" title=" N-terminal pro-brain natriuretic peptide"> N-terminal pro-brain natriuretic peptide</a> </p> <a href="https://publications.waset.org/abstracts/157181/comparative-efficacy-of-angiotensin-converting-enzymes-inhibitors-and-angiotensin-receptor-blockers-in-patients-with-heart-failure-in-tanzania-a-prospective-cohort-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157181.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">85</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">136</span> Evaluating the Probability of Foreign Tourists' Return to the City of Mashhad, Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Rahim%20Rahnama">Mohammad Rahim Rahnama</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20Ali%20Kharazmi"> Amir Ali Kharazmi</a>, <a href="https://publications.waset.org/abstracts/search?q=Safiye%20Rokni"> Safiye Rokni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The tourism industry will be the most important unlimited, sustainable source of income after the oil and automotive industries by 2020 and not only countries, but cities are striving to apprehend its various facets. In line with this objective, the present descriptive-analytical study, through survey and using a questionnaire, seeks to evaluate the probability of tourists’ return and their recommendation to their countrymen to travel to Mashhad, Iran. The population under study is a sample of 384 foreign tourists who, in 2016, arrived at Mashhad, the second metropolis in Iran and its biggest religious city. The Kaplan-Meier estimator was used to analyze the data. Twenty-six percent of the tourists are female and 74% are male. On average, each tourist has had 3.02 trips abroad and 2.1 trips to Mashhad. Tourists from 14 different countries have arrived at Mashhad. Kuwait (15.9%), Armenia (15.6%), and Iraq (10.9%) were the countries where most tourists originated. Seventy-six percent of the tourists traveled with family and 90% of the tourists arrived at Mashhad via airplane. Major purposes of tourists’ trip include pilgrimage (27.9%), treatment (22.1%) followed by pilgrimage and treatment combined (35.4%). Major issues for tourists, in the order of priority, include quality of goods and services (30.2%), shopping (18%), and inhabitants’ treatment of foreigners (15.9%). Main tourist attractions, in addition to the Holy Shrine of Imam Reza, include Torqabeh and Shandiz (Torqabeh 40.9% and Shandiz 29.9%), Neyshabour (18.2%) followed by Kalat, 4.4%. The average willingness to return among tourists is 3.13, which is higher than the mean 3, indicating satisfaction with the stay in Mashhad. Similarly, the average for tourists’ recommending to their countrymen to visit Mashhad is 3.42, which is also an indicator of tourists’ satisfaction with their presence in Mashhad. According to the findings of the Kaplan-Meier estimator, an increase in the number of tourists’ trips to Mashhad, and an increase in the number of tourists’ foreign trips, reduces the probability of recommending a trip to Mashhad by tourists. Similarly, willingness to return is higher among those who stayed at a relatives’ home compared with other patterns of residence (hotels, self-catering accommodation, and pilgrim houses). Therefore, addressing the issues raised by tourists is essential for their return and their recommendation to others to travel to Mashhad. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=international%20tourist" title="international tourist">international tourist</a>, <a href="https://publications.waset.org/abstracts/search?q=probability%20of%20return" title=" probability of return"> probability of return</a>, <a href="https://publications.waset.org/abstracts/search?q=satisfaction" title=" satisfaction"> satisfaction</a>, <a href="https://publications.waset.org/abstracts/search?q=Mashhad" title=" Mashhad"> Mashhad</a> </p> <a href="https://publications.waset.org/abstracts/87099/evaluating-the-probability-of-foreign-tourists-return-to-the-city-of-mashhad-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87099.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">170</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">135</span> Atmospheric Plasma Treatment to Improve Water and Oil Repellent Finishing for PET and PET/Spandex Fabrics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehtap%20%C3%87al%C4%B1%C5%9Fkan">Mehtap Çalışkan</a>, <a href="https://publications.waset.org/abstracts/search?q=Nil%C3%BCfer%20Y%C4%B1ld%C4%B1z%20Varan"> Nilüfer Yıldız Varan</a>, <a href="https://publications.waset.org/abstracts/search?q=Volkan%20Kaplan"> Volkan Kaplan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the effects of an atmospheric plasma treatment on the durability of water and oil repellent finishes of PET and PET/Spandex fabrics were tested.

Creating impactful usage is instrumental to justify the resources for long-term preservation. The Museum für Gestaltung of Zurich holds one of the biggest poster collections of the world from which 52’000 were digitised. In the process of building a digital installation to valorize the collection, one objective was to develop an algorithm capable of predicting the next poster to show according to the ones already displayed. The work presented here describes the steps to build an algorithm able to automatically create sequences of posters reflecting associations performed by curator and professional designers. The exposed challenge finds similarities with the domain of song playlist algorithms. Recently, artificial intelligence techniques and more specifically, deep-learning algorithms have been used to facilitate their generations. Promising results were found thanks to Recurrent Neural Networks (RNN) trained on manually generated playlist and paired with clusters of extracted features from songs. We used the same principles to create the proposed algorithm but applied to a challenging medium, posters. First, a convolutional autoencoder was trained to extract features of the posters. The 52’000 digital posters were used as a training set. Poster features were then clustered. Next, an RNN learned to predict the next cluster according to the previous ones. RNN training set was composed of poster sequences extracted from a collection of books from the Gestaltung Museum of Zurich dedicated to displaying posters. Finally, within the predicted cluster, the poster with the best proximity compared to the previous poster is selected. The mean square distance between features of posters was used to compute the proximity. To validate the predictive model, we compared sequences of 15 posters produced by our model to randomly and manually generated sequences. Manual sequences were created by a professional graphic designer. We asked 21 participants working as professional graphic designers to sort the sequences from the one with the strongest graphic line to the one with the weakest and to motivate their answer with a short description. The sequences produced by the designer were ranked first 60%, second 25% and third 15% of the time. The sequences produced by our predictive model were ranked first 25%, second 45% and third 30% of the time. The sequences produced randomly were ranked first 15%, second 29%, and third 55% of the time. Compared to designer sequences, and as reported by participants, model and random sequences lacked thematic continuity. According to the results, the proposed model is able to generate better poster sequencing compared to random sampling. Eventually, our algorithm is sometimes able to outperform a professional designer. As a next step, the proposed algorithm should include a possibility to create sequences according to a selected theme. To conclude, this work shows the potentiality of artificial intelligence techniques to learn from existing content and provide a tool to curate large sets of data, with a permanent renewal of the presented content. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Artificial%20Intelligence" title="Artificial Intelligence">Artificial Intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=Digital%20Humanities" title=" Digital Humanities"> Digital Humanities</a>, <a href="https://publications.waset.org/abstracts/search?q=serendipity" title=" serendipity"> serendipity</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20research" title=" design research"> design research</a> </p> <a href="https://publications.waset.org/abstracts/137502/automatic-content-curation-of-visual-heritage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137502.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">184</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">133</span> Numerical Simulation of Truck Collision with Road Blocker </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Engin%20Metin%20Kaplan">Engin Metin Kaplan</a>, <a href="https://publications.waset.org/abstracts/search?q=Kemal%20Yaman"> Kemal Yaman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the crash of a medium heavy vehicle onto a designed Road blocker (vehicle barrier) is studied numerically.

We show that, amazingly, the sudden transition between the usual matter dominated decelerated expansion law a(t) ∝ t²/³ and this accelerated expansion law a(t) ∝ t² predicted by the theory should be able to fit the main cosmological probes (SN, BAO, CMB and age of the oldest stars data) but also direct H₀ measurements with two free parameters only: H₀ and the transition redshift. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-gravity" title="anti-gravity">anti-gravity</a>, <a href="https://publications.waset.org/abstracts/search?q=negative%20energies" title=" negative energies"> negative energies</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20reversal" title=" time reversal"> time reversal</a>, <a href="https://publications.waset.org/abstracts/search?q=field%20discontinuities" title=" field discontinuities"> field discontinuities</a>, <a href="https://publications.waset.org/abstracts/search?q=dark%20energy%20theory" title=" dark energy theory"> dark energy theory</a> </p> <a href="https://publications.waset.org/abstracts/185998/dark-gravity-confronted-with-supernovae-baryonic-oscillations-and-cosmic-microwave-background-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185998.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">56</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">128</span> Low SPOP Expression and High MDM2 expression Are Associated with Tumor Progression and Predict Poor Prognosis in Hepatocellular Carcinoma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chang%20Liang">Chang Liang</a>, <a href="https://publications.waset.org/abstracts/search?q=Weizhi%20Gong"> Weizhi Gong</a>, <a href="https://publications.waset.org/abstracts/search?q=Yan%20Zhang"> Yan Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: Hepatocellular carcinoma (HCC) is a malignant tumor with a high mortality rate and poor prognosis worldwide. Murine double minute 2 (MDM2) regulates the tumor suppressor p53, increasing cancer risk and accelerating tumor progression. Speckle-type POX virus and zinc finger protein (SPOP), a key of subunit of Cullin-Ring E3 ligase, inhibits tumor genesis and progression by the ubiquitination of its downstream substrates. This study aimed to clarify whether SPOP and MDM2 are mutually regulated in HCC and the correlation between SPOP and MDM2 and the prognosis of HCC patients. Methods: First, the expression of SPOP and MDM2 in HCC tissues were detected by TCGA database. Then, 53 paired samples of HCC tumor and adjacent tissues were collected to evaluate the expression of SPOP and MDM2 using immunohistochemistry. Chi-square test or Fisher’s exact test were used to analyze the relationship between clinicopathological features and the expression levels of SPOP and MDM2. In addition, Kaplan‒Meier curve analysis and log-rank test were used to investigate the effects of SPOP and MDM2 on the survival of HCC patients. Last, the Multivariate Cox proportional risk regression model analyzed whether the different expression levels of SPOP and MDM2 were independent risk factors for the prognosis of HCC patients. Results: Bioinformatics analysis revealed the low expression of SPOP and high expression of MDM2 were related to worse prognosis of HCC patients. The relationship between the expression of SPOP and MDM2 and tumor stem-like features showed an opposite trend. The immunohistochemistry showed the expression of SPOP protein was significantly downregulated while MDM2 protein significantly upregulated in HCC tissue compared to that in para-cancerous tissue. Tumors with low SPOP expression were related to worse T stage and Barcelona Clinic Liver Cancer (BCLC) stage, but tumors with high MDM2 expression were related to worse T stage, M stage, and BCLC stage. Kaplan–Meier curves showed HCC patients with high SPOP expression and low MDM2 expression had better survival than those with low SPOP expression and high MDM2 expression (P < 0.05). A multivariate Cox proportional risk regression model confirmed that a high MDM2 expression level was an independent risk factor for poor prognosis in HCC patients (P <0.05). Conclusion: The expression of SPOP protein was significantly downregulated, while the expression of MDM2 significantly upregulated in HCC. The low expression of SPOP and high expression. of MDM2 were associated with malignant progression and poor prognosis of HCC patients, indicating a potential therapeutic target for HCC patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hepatocellular%20carcinoma" title="hepatocellular carcinoma">hepatocellular carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=murine%20double%20minute%202" title=" murine double minute 2"> murine double minute 2</a>, <a href="https://publications.waset.org/abstracts/search?q=speckle-type%20POX%20virus%20and%20zinc%20finger%20protein" title=" speckle-type POX virus and zinc finger protein"> speckle-type POX virus and zinc finger protein</a>, <a href="https://publications.waset.org/abstracts/search?q=ubiquitination" title=" ubiquitination"> ubiquitination</a> </p> <a href="https://publications.waset.org/abstracts/148798/low-spop-expression-and-high-mdm2-expression-are-associated-with-tumor-progression-and-predict-poor-prognosis-in-hepatocellular-carcinoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148798.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">127</span> Introduction of the Fluid-Structure Coupling into the Force Analysis Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oc%C3%A9ane%20Grosset">Océane Grosset</a>, <a href="https://publications.waset.org/abstracts/search?q=Charles%20P%C3%A9zerat"> Charles Pézerat</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-Hugh%20Thomas"> Jean-Hugh Thomas</a>, <a href="https://publications.waset.org/abstracts/search?q=Fr%C3%A9d%C3%A9ric%20Ablitzer"> Frédéric Ablitzer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a method to take into account the fluid-structure coupling into an inverse method, the Force Analysis Technique (FAT). The FAT method, also called RIFF method (Filtered Windowed Inverse Resolution), allows to identify the force distribution from local vibration field. In order to only identify the external force applied on a structure, it is necessary to quantify the fluid-structure coupling, especially in naval application, where the fluid is heavy. This method can be decomposed in two parts, the first one consists in identifying the fluid-structure coupling and the second one to introduced it in the FAT method to reconstruct the external force.

This disease can be deadly if a part or the whole thrombus reaches the lung and causes a Pulmonary Embolism (PE). This disorder, often asymptomatic, has multifactorial causes: immobilization, surgery, pregnancy, age, cancers, and genetic variations. Our project aims to relate the thrombus epidemiology (origins, patient predispositions, PE) to its structure using ultrasound images. Ultrasonography and elastography were collected using Toshiba Aplio 500 at Brest Hospital. This manuscript compares two classification approaches: spectral clustering and scattering operator. The former is based on the graph and matrix theories while the latter cascades wavelet convolutions with nonlinear modulus and averaging operators. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deep%20venous%20thrombosis" title="deep venous thrombosis">deep venous thrombosis</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasonography" title=" ultrasonography"> ultrasonography</a>, <a href="https://publications.waset.org/abstracts/search?q=elastography" title=" elastography"> elastography</a>, <a href="https://publications.waset.org/abstracts/search?q=scattering%20operator" title=" scattering operator"> scattering operator</a>, <a href="https://publications.waset.org/abstracts/search?q=wavelet" title=" wavelet"> wavelet</a>, <a href="https://publications.waset.org/abstracts/search?q=spectral%20clustering" title=" spectral clustering"> spectral clustering</a> </p> <a href="https://publications.waset.org/abstracts/80700/scattering-operator-and-spectral-clustering-for-ultrasound-images-application-on-deep-venous-thrombi" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80700.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">479</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">124</span> Characterization of Internet Exchange Points by Using Quantitative Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yamba%20Dabone">Yamba Dabone</a>, <a href="https://publications.waset.org/abstracts/search?q=Tounwendyam%20Fr%C3%A9d%C3%A9ric%20Ouedraogo"> Tounwendyam Frédéric Ouedraogo</a>, <a href="https://publications.waset.org/abstracts/search?q=Pengwend%C3%A9%20Justin%20Kouraogo"> Pengwendé Justin Kouraogo</a>, <a href="https://publications.waset.org/abstracts/search?q=Oumarou%20Sie"> Oumarou Sie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Reliable data transport over the Internet is one of the goals of researchers in the field of computer science. Data such as videos and audio files are becoming increasingly large. As a result, transporting them over the Internet is becoming difficult. Therefore, it has been important to establish a method to locally interconnect autonomous systems (AS) with each other to facilitate traffic exchange. It is in this context that Internet Exchange Points (IXPs) are set up to facilitate local and even regional traffic. They are now the lifeblood of the Internet. Therefore, it is important to think about the factors that can characterize IXPs. However, other more quantifiable characteristics can help determine the quality of an IXP. In addition, these characteristics may allow ISPs to have a clearer view of the exchange node and may also convince other networks to connect to an IXP. To that end, we define five new IXP characteristics: the attraction rate (τₐₜₜᵣ); and the peering rate (τₚₑₑᵣ); the target rate of an IXP (Objₐₜₜ); the number of IXP links (Nₗᵢₙₖ); the resistance rate τₑ𝒻𝒻 and the attraction failure rate (τ𝒻). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=characteristic" title="characteristic">characteristic</a>, <a href="https://publications.waset.org/abstracts/search?q=autonomous%20system" title=" autonomous system"> autonomous system</a>, <a href="https://publications.waset.org/abstracts/search?q=internet%20service%20provider" title=" internet service provider"> internet service provider</a>, <a href="https://publications.waset.org/abstracts/search?q=internet%20exchange%20point" title=" internet exchange point"> internet exchange point</a>, <a href="https://publications.waset.org/abstracts/search?q=rate" title=" rate"> rate</a> </p> <a href="https://publications.waset.org/abstracts/154515/characterization-of-internet-exchange-points-by-using-quantitative-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154515.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">94</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">123</span> Effect of Drop Impact Behavior on Spray Retention</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hassina%20Hafida%20Boukhalfa">Hassina Hafida Boukhalfa</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Massinon"> Mathieu Massinon</a>, <a href="https://publications.waset.org/abstracts/search?q=Fr%C3%A9deric%20Lebeau"> Fréderic Lebeau</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Belhamra"> Mohamed Belhamra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Drop behaviour during impact affects retention. The increase of adhesion is usually seen as the objective when applying crop protection products, while bouncing and shattering are seen as detrimental to spray retention. However, observation of drop impacts using high speed shadow graphy shows that fragmentation can occur in Wenzel wetting regime. In this case, a part of the drop sticks on the surface, what contributes to retention. Using simultaneous measurements of drop impacts with high speed imaging and of retention with fluorometry for 3 spray mixtures on excised barley leaves allowed us to observe that about 50% of the drops fragmented in Wenzel state remain on the leaf. Depending on spray mixture, these impact outcomes accounted for 25 to 50% of retention, the higher contribution being correlated with bigger VMD (Volume Median Diameter). This contribution is non-negligible and should be considered when a modelling of spray retention process is performed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drop%20impact" title="drop impact">drop impact</a>, <a href="https://publications.waset.org/abstracts/search?q=retention" title=" retention"> retention</a>, <a href="https://publications.waset.org/abstracts/search?q=fluorometry" title=" fluorometry"> fluorometry</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20speed%20imaging" title=" high speed imaging"> high speed imaging</a> </p> <a href="https://publications.waset.org/abstracts/47237/effect-of-drop-impact-behavior-on-spray-retention" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47237.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">381</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">122</span> An Improved Ant Colony Algorithm for Genome Rearrangements</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Essam%20Al%20Daoud">Essam Al Daoud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Genome rearrangement is an important area in computational biology and bioinformatics. The basic problem in genome rearrangements is to compute the edit distance, i.e., the minimum number of operations needed to transform one genome into another. Unfortunately, unsigned genome rearrangement problem is NP-hard. In this study an improved ant colony optimization algorithm to approximate the edit distance is proposed. The main idea is to convert the unsigned permutation to signed permutation and evaluate the ants by using Kaplan algorithm. Two new operations are added to the standard ant colony algorithm: Replacing the worst ants by re-sampling the ants from a new probability distribution and applying the crossover operations on the best ants. The proposed algorithm is tested and compared with the improved breakpoint reversal sort algorithm by using three datasets. The results indicate that the proposed algorithm achieves better accuracy ratio than the previous methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ant%20colony%20algorithm" title="ant colony algorithm">ant colony algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=edit%20distance" title=" edit distance"> edit distance</a>, <a href="https://publications.waset.org/abstracts/search?q=genome%0D%0Abreakpoint" title=" genome breakpoint"> genome breakpoint</a>, <a href="https://publications.waset.org/abstracts/search?q=genome%20rearrangement" title=" genome rearrangement"> genome rearrangement</a>, <a href="https://publications.waset.org/abstracts/search?q=reversal%20sort" title=" reversal sort"> reversal sort</a> </p> <a href="https://publications.waset.org/abstracts/5601/an-improved-ant-colony-algorithm-for-genome-rearrangements" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5601.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">121</span> Time Series Analysis of Radon Concentration at Different Depths in an Underground Goldmine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Theophilus%20Adjirackor">Theophilus Adjirackor</a>, <a href="https://publications.waset.org/abstracts/search?q=Frederic%20Sam"> Frederic Sam</a>, <a href="https://publications.waset.org/abstracts/search?q=Irene%20Opoku-Ntim"> Irene Opoku-Ntim</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Okoh%20Kpeglo"> David Okoh Kpeglo</a>, <a href="https://publications.waset.org/abstracts/search?q=Prince%20K.%20Gyekye"> Prince K.

The detectors were installed in batches within four quarters. The measurements were carried out using LR115 solid-state nuclear track detectors. Statistical models are applied in the prediction and analysis of the radon concentration at various depths. The time series model predicted a positive relationship between the depth of the underground mine and the indoor radon concentration. Thus, elevated radon concentrations are expected at deeper levels of the underground mine, but the relationship was insignificant at the 5% level of significance with a negative adjusted R2 (R2 = – 0.021) due to an appropriate engineering and adequate ventilation rate in the underground mine. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LR115" title="LR115">LR115</a>, <a href="https://publications.waset.org/abstracts/search?q=radon%20concentration" title=" radon concentration"> radon concentration</a>, <a href="https://publications.waset.org/abstracts/search?q=rime%20series" title=" rime series"> rime series</a>, <a href="https://publications.waset.org/abstracts/search?q=underground%20goldmine" title=" underground goldmine"> underground goldmine</a> </p> <a href="https://publications.waset.org/abstracts/186013/time-series-analysis-of-radon-concentration-at-different-depths-in-an-underground-goldmine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186013.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">45</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">120</span> Risk Tolerance and Individual Worthiness Based on Simultaneous Analysis of the Cognitive Performance and Emotional Response to a Multivariate Situational Risk Assessment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Frederic%20Jumelle">Frederic Jumelle</a>, <a href="https://publications.waset.org/abstracts/search?q=Kelvin%20So"> Kelvin So</a>, <a href="https://publications.waset.org/abstracts/search?q=Didan%20Deng"> Didan Deng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A method and system for neuropsychological performance test, comprising a mobile terminal, used to interact with a cloud server which stores user information and is logged into by the user through the terminal device; the user information is directly accessed through the terminal device and is processed by artificial neural network, and the user information comprises user facial emotions information, performance test answers information and user chronometrics.

However, current analysis is limited to the low frequency range. At medium and high frequencies, a rotational component appear in the field, masking the energy flow and make its understanding difficult or impossible. The objective of this work is to implement a methodology to filter out the rotational components of the structural intensity field in order to fully understand the energy flow in complex structures. The approach is based on the Helmholtz decomposition. It allows to decompose the structural intensity field into rotational, irrotational, and harmonic components. Only the irrotational component is needed to describe the net power flow from a source to a dissipative zone in the structure. The methodology has been applied on academic structures, and it allows a good analysis of the energy transfer paths. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=structural%20intensity" title="structural intensity">structural intensity</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20flow" title=" power flow"> power flow</a>, <a href="https://publications.waset.org/abstracts/search?q=helmholt%20decomposition" title=" helmholt decomposition"> helmholt decomposition</a>, <a href="https://publications.waset.org/abstracts/search?q=irrotational%20intensity" title=" irrotational intensity"> irrotational intensity</a> </p> <a href="https://publications.waset.org/abstracts/143536/vibration-propagation-in-structures-through-structural-intensity-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143536.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">178</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">118</span> Hedonistic Utilitarianism: The Strategic Use of Digital Media along the Online-Offline Continuum of Sexualised Violence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Kargel">Katharina Kargel</a>, <a href="https://publications.waset.org/abstracts/search?q=Frederic%20Vobbe"> Frederic Vobbe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study examines how offenders targeting children and adolescents strategically use digital media when committing acts of sexualised violence along the online-offline continuum. Even offenders who are previously known to their victims use digital media extensively. The choice to instrumentalise digital media in order to initiate, threaten, exploit and humiliate victims demonstrates the rationale of offenders when committing acts of digitally supported violence. Through digital media, offenders can assume the power of interpretation over their victims’ situations. The ways in which digital media is used to commit violence along the online-offline continuum are a direct manifestation of the hedonistic utilitarianism demonstrated by offenders: a disposition characterised by the weighing of pleasures (“mental states”) and intrinsic value expected from using digital media against the risk of an outcome subjectively experienced as uncomfortable. Thus, sexualised violence using digital media goes beyond the traditional understanding of sexual online grooming. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sexualized%20violence" title="sexualized violence">sexualized violence</a>, <a href="https://publications.waset.org/abstracts/search?q=offender%20strategy" title=" offender strategy"> offender strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=grooming" title=" grooming"> grooming</a>, <a href="https://publications.waset.org/abstracts/search?q=children%20and%20adolescents" title=" children and adolescents"> children and adolescents</a>, <a href="https://publications.waset.org/abstracts/search?q=qualitative%20research" title=" qualitative research"> qualitative research</a>, <a href="https://publications.waset.org/abstracts/search?q=methodology" title=" methodology"> methodology</a> </p> <a href="https://publications.waset.org/abstracts/139518/hedonistic-utilitarianism-the-strategic-use-of-digital-media-along-the-online-offline-continuum-of-sexualised-violence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139518.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">221</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">117</span> Transient Free Laminar Convection in the Vicinity of a Thermal Conductive Vertical Plate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anna%20Bykalyuk">Anna Bykalyuk</a>, <a href="https://publications.waset.org/abstracts/search?q=Fr%C3%A9d%C3%A9ric%20Kuznik"> Frédéric Kuznik</a>, <a href="https://publications.waset.org/abstracts/search?q=K%C3%A9vyn%20Johannes"> Kévyn Johannes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the influence of a vertical plate’s thermal capacity is numerically investigated in order to evaluate the evolution of the thermal boundary layer structure, as well as the convective heat transfer coefficient and the velocity and temperature profiles. Whereas the heat flux of the heated vertical plate is evaluated under time depending boundary conditions. The main important feature of this problem is the unsteadiness of the physical phenomena. A 2D CFD model is developed with the Ansys Fluent 14.0 environment and is validated using unsteady data obtained for plasterboard studied under a dynamic temperature evolution. All the phenomena produced in the vicinity of the thermal conductive vertical plate (plasterboard) are analyzed and discussed. This work is the first stage of a holistic research on transient free convection that aims, in the future, to study the natural convection in the vicinity of a vertical plate containing Phase Change Materials (PCM). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CFD%20modeling" title="CFD modeling">CFD modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20convection" title=" natural convection"> natural convection</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20conductive%20plate" title=" thermal conductive plate"> thermal conductive plate</a>, <a href="https://publications.waset.org/abstracts/search?q=time-depending%20boundary%20conditions" title=" time-depending boundary conditions"> time-depending boundary conditions</a> </p> <a href="https://publications.waset.org/abstracts/1371/transient-free-laminar-convection-in-the-vicinity-of-a-thermal-conductive-vertical-plate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1371.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">277</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">116</span> Effect of Film Cooling on Gas-Turbine Engine Turbine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Burak%20Kaplan">Burak Kaplan</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%9Cnver%20Kaynak"> Ünver Kaynak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Gas turbine engines, crucial for modern aviation and power generation, rely on the efficient operation of turbine blades. However, extreme temperatures and pressures can lead to material degradation and failure. Film cooling, a widely employed technique, injects a coolant onto the blade surface to mitigate the effects of hot gas exposure. This research investigates the impact of film cooling on gas turbine engine performance, focusing on its influence on efficiency, longevity, and overall engine performance. Through a comprehensive literature review, computational fluid dynamics simulations, and thermal performance analysis, this study aims to provide insights into optimizing film cooling configurations for enhanced engine performance. The research explores the thermal performance characteristics of turbine blades with and without film cooling, the influence of various film cooling techniques on engine efficiency, and the design factors that optimize film cooling effectiveness. The findings of this study have the potential to contribute to the development of more efficient and reliable gas turbine engines, ultimately advancing the field of gas turbine technology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gas%20turbine" title="gas turbine">gas turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=engine" title=" engine"> engine</a>, <a href="https://publications.waset.org/abstracts/search?q=cooling" title=" cooling"> cooling</a>, <a href="https://publications.waset.org/abstracts/search?q=blade" title=" blade"> blade</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a> </p> <a href="https://publications.waset.org/abstracts/195371/effect-of-film-cooling-on-gas-turbine-engine-turbine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/195371.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">2</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">115</span> Customizable Sonic EEG Neurofeedback Environment to Train Self-Regulation of Momentary Mental and Emotional State</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cyril%20Kaplan">Cyril Kaplan</a>, <a href="https://publications.waset.org/abstracts/search?q=Nikola%20Jajcay"> Nikola Jajcay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We developed purely sonic, musical based, highly customizable EEG neurofeedback environment designed to administer a new neurofeedback training protocol. The training protocol concentrates on improving the ability to switch between several mental states characterized by different levels of arousal, each of them correlated to specific brain wave activity patterns in several specific regions of neocortex. This paper describes the neurofeedback training environment we developed and its specificities, thus can be helpful as a manual to guide other neurofeedback users (both researchers and practitioners) interested in our editable open source program (available to download and usage under CC license). Responses and reaction of first trainees that used our environment are presented in this article. Combination of qualitative methods (thematic analysis of neurophenomenological insights of trainees and post-session semi-structured interviews) and quantitative methods (power spectra analysis of EEG recorded during the training) were employed to obtain a multifaceted view on our new training protocol. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EEG%20neurofeedback" title="EEG neurofeedback">EEG neurofeedback</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20methods" title=" mixed methods"> mixed methods</a>, <a href="https://publications.waset.org/abstracts/search?q=self-regulation" title=" self-regulation"> self-regulation</a>, <a href="https://publications.waset.org/abstracts/search?q=switch-between-states%20training" title=" switch-between-states training "> switch-between-states training </a> </p> <a href="https://publications.waset.org/abstracts/85645/customizable-sonic-eeg-neurofeedback-environment-to-train-self-regulation-of-momentary-mental-and-emotional-state" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85645.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">227</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">114</span> WebAppShield: An Approach Exploiting Machine Learning to Detect SQLi Attacks in an Application Layer in Run-time</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Abdulla%20Ashlam">Ahmed Abdulla Ashlam</a>, <a href="https://publications.waset.org/abstracts/search?q=Atta%20Badii"> Atta Badii</a>, <a href="https://publications.waset.org/abstracts/search?q=Frederic%20Stahl"> Frederic Stahl</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, SQL injection attacks have been identified as being prevalent against web applications. They affect network security and user data, which leads to a considerable loss of money and data every year. This paper presents the use of classification algorithms in machine learning using a method to classify the login data filtering inputs into "SQLi" or "Non-SQLi,” thus increasing the reliability and accuracy of results in terms of deciding whether an operation is an attack or a valid operation. A method Web-App auto-generated twin data structure replication. Shielding against SQLi attacks (WebAppShield) that verifies all users and prevents attackers (SQLi attacks) from entering and or accessing the database, which the machine learning module predicts as "Non-SQLi" has been developed. A special login form has been developed with a special instance of data validation; this verification process secures the web application from its early stages. The system has been tested and validated, up to 99% of SQLi attacks have been prevented. <p class="card-text"><strong>Keywords:</strong> <a
