energy storage technologies and their parameters for the economic operation of a microgrid. A grid-connected system with local loads and PV generation is assumed, where an energy storage system (ESS) is attached to minimize energy cost by providing energy balancing and arbitrage functionalities. The ESS operates in a hybrid configuration and consists of two unique technologies operated in a coordinated way. Based on given energy profiles and economical data a model calculates financial flow for ESS investment, including energy cost and ESS depreciation resulting from degradation. The optimization strategy proposes a hybrid set of two technologies with their respective power and energy ratings to minimize overall system cost in a given timeframe. Results are validated through microgrid simulations using real-life input profiles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20storage" title="energy storage">energy storage</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20energy%20storage" title=" hybrid energy storage"> hybrid energy storage</a>, <a href="https://publications.waset.org/abstracts/search?q=cost-benefit%20analysis" title=" cost-benefit analysis"> cost-benefit analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=microgrid" title=" microgrid"> microgrid</a>, <a href="https://publications.waset.org/abstracts/search?q=battery%20sizing" title=" battery sizing"> battery sizing</a> </p> <a href="https://publications.waset.org/abstracts/141372/methodology-of-choosing-technology-and-sizing-of-the-hybrid-energy-storage-based-on-cost-benefit-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141372.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">220</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">55</span> Motor Coordination and Body Mass Index in Primary School Children</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ingrid%20Ruzbarska">Ingrid Ruzbarska</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20Zvonar"> Martin Zvonar</a>, <a href="https://publications.waset.org/abstracts/search?q=Piotr%20Ole%C5%9Bniewicz"> Piotr Oleśniewicz</a>, <a href="https://publications.waset.org/abstracts/search?q=Julita%20Markiewicz-Patkowska"> Julita Markiewicz-Patkowska</a>, <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Widawski"> Krzysztof Widawski</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Puciato"> Daniel Puciato</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Obese children will probably become obese adults, consequently exposed to an increased risk of comorbidity and premature mortality. Body weight may be indirectly determined by continuous development of coordination and motor skills. The level of motor skills and abilities is an important factor that promotes physical activity since early childhood. The aim of the study is to thoroughly understand the internal relations between motor coordination abilities and the somatic development of prepubertal children and to determine the effect of excess body weight on motor coordination by comparing the motor ability levels of children with different body mass index (BMI) values. The data were collected from 436 children aged 7–10 years, without health limitations, fully participating in school physical education classes. Body height was measured with portable stadiometers (Harpenden, Holtain Ltd.), and body mass—with a digital scale (HN-286, Omron). Motor coordination was evaluated with the Kiphard-Schilling body coordination test, Körperkoordinationstest für Kinder. The normality test by Shapiro-Wilk was used to verify the data distribution. The correlation analysis revealed a statistically significant negative association between the dynamic balance and BMI, as well as between the motor quotient and BMI (p<0.01) for both boys and girls. The results showed no effect of gender on the difference in the observed trends. The analysis of variance proved statistically significant differences between normal weight children and their overweight or obese counterparts. Coordination abilities probably play an important role in preventing or moderating the negative trajectory leading to childhood overweight and obesity. At this age, the development of coordination abilities should become a key strategy, targeted at long-term prevention of obesity and the promotion of an active lifestyle in adulthood. Motor performance is essential for implementing a healthy lifestyle in childhood already. Physical inactivity apparently results in motor deficits and a sedentary lifestyle in children, which may be accompanied by excess energy intake and overweight. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=childhood" title="childhood">childhood</a>, <a href="https://publications.waset.org/abstracts/search?q=KTK%20test" title=" KTK test"> KTK test</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20education" title=" physical education"> physical education</a>, <a href="https://publications.waset.org/abstracts/search?q=psychomotor%20competence" title=" psychomotor competence"> psychomotor competence</a> </p> <a href="https://publications.waset.org/abstracts/52096/motor-coordination-and-body-mass-index-in-primary-school-children" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52096.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">342</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">54</span> Motion Capture Based Wizard of Oz Technique for Humanoid Robot</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rafal%20Stegierski">Rafal Stegierski</a>, <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Dmitruk"> Krzysztof Dmitruk</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper focuses on robotic tele-presence system build around humanoid robot operated with controller-less Wizard of Oz technique.

That refers particularly to professionally active people, including the early senior group working on non-manual positions. The aim of the study is to evaluate the relationship between physical activity and the socio-economic status of non-manual workers from Wroclaw—one of the biggest cities in Poland, a model setting for such investigations in this part of Europe. The crucial problem in the research is to find out the percentage of respondents who meet the health-related recommendations of the World Health Organization (WHO) concerning the volume, frequency, and intensity of physical activity, as well as to establish if the most important socio-economic factors, such as gender, age, education, marital status, per capita income, savings and debt, determine the compliance with the WHO physical activity recommendations. During the research, conducted in 2013, 1,170 people (611 women and 559 men) aged 21–60 years were examined. A diagnostic poll method was applied to collect the data. Physical activity was measured with the use of the short form of the International Physical Activity Questionnaire with extended socio-demographic questions, i.e. concerning gender, age, education, marital status, income, savings or debts. To evaluate the relationship between physical activity and selected socio-economic factors, logistic regression was used (odds ratio statistics). Statistical inference was conducted on the adopted ex ante probability level of p<0.05. The majority of respondents met the volume of physical effort recommended for health benefits. It was particularly noticeable in the case of the examined men. The probability of compliance with the WHO physical activity recommendations was highest for workers aged 21–30 years with secondary or higher education who were single, received highest incomes and had savings. The results indicate the relations between physical activity and socio-economic status in the examined women and men. People with lower socio-economic status (e.g. manual workers) are physically active primarily at work, whereas those better educated and wealthier implement physical effort primarily in their leisure time. Among the investigated subjects, the youngest group of non-manual workers have the best chances to meet the WHO standards of physical activity. The study also confirms that secondary education has a positive effect on the public awareness on the role of physical activity in human life. In general, the analysis of the research indicates that there is a relationship between physical activity and some socio-economic factors of the respondents, such as gender, age, education, marital status, income per capita, and the possession of savings. Although the obtained results cannot be applied for the general population, they show some important trends that will be verified in subsequent studies conducted by the authors of the paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=IPAQ" title="IPAQ">IPAQ</a>, <a href="https://publications.waset.org/abstracts/search?q=nonmanual%20workers" title=" nonmanual workers"> nonmanual workers</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=socioeconomic%20factors" title=" socioeconomic factors"> socioeconomic factors</a>, <a href="https://publications.waset.org/abstracts/search?q=WHO" title=" WHO"> WHO</a> </p> <a href="https://publications.waset.org/abstracts/52092/socio-economic-determinants-of-physical-activity-of-non-manual-workers-including-the-early-senior-group-from-the-city-of-wroclaw-in-poland" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52092.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">535</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">52</span> Normal Weight Obesity among Female Students: BMI as a Non-Sufficient Tool for Obesity Assessment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Plesiewicz">Krzysztof Plesiewicz</a>, <a href="https://publications.waset.org/abstracts/search?q=Izabela%20Plesiewicz"> Izabela Plesiewicz</a>, <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Chi%C5%BCy%C5%84ski"> Krzysztof Chiżyński</a>, <a href="https://publications.waset.org/abstracts/search?q=Marzenna%20Zieli%C5%84ska"> Marzenna Zielińska</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Obesity is an independent risk factor for cardiovascular diseases. There are several anthropometric parameters proposed to estimate the level of obesity, but until now there is no agreement which one is the best predictor of cardiometabolic risk. Scientists defined metabolically obese normal weight, who suffer from metabolic abnormalities, the same as obese individuals, and defined this syndrome as normal weight obesity (NWO). Aim of the study: The aim of our study was to determine the occurrence of overweight and obesity in a cohort of young, adult women, using standard and complementary methods of obesity assessment and to indicate those, who are at risk of obesity. The second aim of our study was to test additional methods of obesity assessment and proof that body mass index using alone is not sufficient parameter of obesity assessment. Materials and methods: 384 young women, aged 18-32, were enrolled into the study. Standard anthropometric parameters (waist to hips ratio (WTH), waist to height ratio (WTHR)) and two other methods of body fat percentage measurement (BFPM) were used in the study: electrical bioimpendance analysis (BIA) and skinfold measurement test by digital fat body mass clipper (SFM). Results: In the study group 5% and 7% of participants had waist to hips ratio and accordingly waist to height ratio values connected with visceral obesity. According to BMI 14% participants were overweight and obese. Using additional methods of body fat assessment, there were 54% and 43% of obese for BIA and SMF method. In the group of participants with normal BMI and underweight (not overweight, n =340) there were individuals with the level of BFPM above the upper limit, for the BIA 49% (n =164) and for the SFM 36 % (n=125). Statistical analysis revealed strong correlation between BIA and SFM methods. Conclusion: BMI using alone is not a sufficient parameter of obesity assessment. High percentage of young women with normal BMI values seem to be normal weight obese. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrical%20bioimpedance" title="electrical bioimpedance">electrical bioimpedance</a>, <a href="https://publications.waset.org/abstracts/search?q=normal%20weight%20obesity" title=" normal weight obesity"> normal weight obesity</a>, <a href="https://publications.waset.org/abstracts/search?q=skin-fold%20measurement%20test" title=" skin-fold measurement test"> skin-fold measurement test</a>, <a href="https://publications.waset.org/abstracts/search?q=women" title=" women"> women</a> </p> <a href="https://publications.waset.org/abstracts/48496/normal-weight-obesity-among-female-students-bmi-as-a-non-sufficient-tool-for-obesity-assessment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48496.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">274</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">51</span> Comparison between Approaches Used in Two Walk About Projects </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Derek%20O%20Reilly">Derek O Reilly</a>, <a href="https://publications.waset.org/abstracts/search?q=Piotr%20Milczarski"> Piotr Milczarski</a>, <a href="https://publications.waset.org/abstracts/search?q=Shane%20Dowdall"> Shane Dowdall</a>, <a href="https://publications.waset.org/abstracts/search?q=Artur%20H%C5%82oba%C5%BC"> Artur Hłobaż</a>, <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Podlaski"> Krzysztof Podlaski</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiram%20Bollaert"> Hiram Bollaert </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Learning through creation of contextual games is a very promising way/tool for interdisciplinary and international group projects.

In this paper, we investigate the preferences of regulators with the aim of understanding why, for instance, a VaR with a given confidence level is ultimately retained. Further, this paper provides equivalence rules that explain how a given choice of VaR can be equivalent to a given choice of TCE. Then, we introduce a new risk indicator that extends TCE by providing a more versatile weighting of the constituents of probability distribution tails. All of our results are illustrated using the generalized Pareto distribution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=generalized%20pareto%20distribution" title="generalized pareto distribution">generalized pareto distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=generalized%20tail%20conditional%20expectation" title=" generalized tail conditional expectation"> generalized tail conditional expectation</a>, <a href="https://publications.waset.org/abstracts/search?q=regulator%20preferences" title=" regulator preferences"> regulator preferences</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20measure" title=" risk measure"> risk measure</a> </p> <a href="https://publications.waset.org/abstracts/146694/var-or-tce-explaining-the-preferences-of-regulators" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146694.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">49</span> Vehicle to Grid Potential for Solar Powered Electric Vehicle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcin%20Kowalski">Marcin Kowalski</a>, <a href="https://publications.waset.org/abstracts/search?q=Tomasz%20Wiktor"> Tomasz Wiktor</a>, <a href="https://publications.waset.org/abstracts/search?q=Piotr%20Ladonski"> Piotr Ladonski</a>, <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Bortnowski"> Krzysztof Bortnowski</a>, <a href="https://publications.waset.org/abstracts/search?q=Szymon%20Przybyl"> Szymon Przybyl</a>, <a href="https://publications.waset.org/abstracts/search?q=Mateusz%20Grzesiak"> Mateusz Grzesiak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper provides a detailed overview of the so-called smart grid or vehicle-to-grid idea, including a description of our way of implementation.

Musical recall is a sample of convergent production that requires intensively focused attention. Inversely, musical improvisation is a divergent task and probably requires a different way of attentional control. The study was designed in dual task paradigm. Participants were to remember a simple melody and then recall or improvise, simultaneously performing the spatial attentional test on computer screen. The result shows that improvising participants find spatial goals in more disperse way. The conclusion is that musical improvisation requires extensification of attention to occur. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attention" title="attention">attention</a>, <a href="https://publications.waset.org/abstracts/search?q=creativity" title=" creativity"> creativity</a>, <a href="https://publications.waset.org/abstracts/search?q=divergent%20task" title=" divergent task"> divergent task</a>, <a href="https://publications.waset.org/abstracts/search?q=musical%20improvisation" title=" musical improvisation"> musical improvisation</a> </p> <a href="https://publications.waset.org/abstracts/60560/attentional-differences-in-musical-recall-and-improvisation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60560.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">233</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">47</span> System Detecting Border Gateway Protocol Anomalies Using Local and Remote Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alicja%20Starczewska">Alicja Starczewska</a>, <a href="https://publications.waset.org/abstracts/search?q=Aleksander%20Nawrat"> Aleksander Nawrat</a>, <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Daniec"> Krzysztof Daniec</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaros%C5%82aw%20Homa"> Jarosław Homa</a>, <a href="https://publications.waset.org/abstracts/search?q=Kacper%20Ho%C5%82da"> Kacper Hołda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Border Gateway Protocol is the main routing protocol that enables routing establishment between all autonomous systems, which are the basic administrative units of the internet.

Resulting optical changes for illuminated DNA were investigated using UV-Vis spectra and photoluminescent. Optical properties show potential application in sensors based on modified DNA. Then selected DNA-surfactant complexes were illuminated with electromagnetic radiation for 5h. Molecular structure, optical characteristic were examinated for obtained complexes. Illumination led to changes of complexes physicochemical properties as compared with native DNA. Observed changes were induced by rearrangement of the molecular structure of DNA chains. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biopolymers" title="biopolymers">biopolymers</a>, <a href="https://publications.waset.org/abstracts/search?q=deoxyribonucleic%20acid" title=" deoxyribonucleic acid"> deoxyribonucleic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=ionic%20liquids" title=" ionic liquids"> ionic liquids</a>, <a href="https://publications.waset.org/abstracts/search?q=linearly%20polarized%20visible%20light" title=" linearly polarized visible light"> linearly polarized visible light</a>, <a href="https://publications.waset.org/abstracts/search?q=ultraviolet" title=" ultraviolet"> ultraviolet</a> </p> <a href="https://publications.waset.org/abstracts/85130/dna-and-dna-complexes-modified-with-electromagnetic-radiation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85130.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">210</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">45</span> Online Authenticity Verification of a Biometric Signature Using Dynamic Time Warping Method and Neural Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ga%C5%82ka%20Aleksandra">Gałka Aleksandra</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeli%C5%84ska%20Justyna"> Jelińska Justyna</a>, <a href="https://publications.waset.org/abstracts/search?q=Masiak%20Albert"> Masiak Albert</a>, <a href="https://publications.waset.org/abstracts/search?q=Walentukiewicz%20Krzysztof"> Walentukiewicz Krzysztof</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An offline signature is well-known however not the safest way to verify identity.

We first examine existing methods in competition practice and statistical literature for discarding or correcting jurors' scores that deviate significantly from the mean or median of all scores. We then introduce a method that involves eliminating all scores of outlier jurors, i.e., those jurors whose ratings significantly differ from those of other jurors. The properties of these standard and proposed methods are discussed in hypothetical voting scenarios, where one or more jurors assign scores that deviate considerably from the scores awarded by other jurors. Finally, we present examples of applying various methods to real-world data from piano competitions, demonstrating the potential effectiveness and implications of each approach in reducing manipulation within these events. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=voting%20systems" title="voting systems">voting systems</a>, <a href="https://publications.waset.org/abstracts/search?q=manipulation" title=" manipulation"> manipulation</a>, <a href="https://publications.waset.org/abstracts/search?q=outlier%20scores" title=" outlier scores"> outlier scores</a>, <a href="https://publications.waset.org/abstracts/search?q=outlier%20jurors" title=" outlier jurors"> outlier jurors</a> </p> <a href="https://publications.waset.org/abstracts/165256/discarding-or-correcting-outlier-scores-vs-excluding-outlier-jurors-to-reduce-manipulation-in-classical-music-competitions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165256.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">84</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">42</span> HR MRI CS Based Image Reconstruction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Malczewski">Krzysztof Malczewski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Magnetic Resonance Imaging (MRI) reconstruction algorithm using compressed sensing is presented in this paper. It is exhibited that the offered approach improves MR images spatial resolution in circumstances when highly undersampled k-space trajectories are applied. Compressed Sensing (CS) aims at signal and images reconstructing from significantly fewer measurements than were conventionally assumed necessary. Magnetic Resonance Imaging (MRI) is a fundamental medical imaging method struggles with an inherently slow data acquisition process. The use of CS to MRI has the potential for significant scan time reductions, with visible benefits for patients and health care economics. In this study the objective is to combine super-resolution image enhancement algorithm with CS framework benefits to achieve high resolution MR output image. Both methods emphasize on maximizing image sparsity on known sparse transform domain and minimizing fidelity.

The measuring systems used nowadays are generally imperfect and there is a strong demand for improvement. The application of a new type of a measurement system called Self-Excited Acoustical System is presented in the paper. The system was applied until now to monitor stress changes in metal and concrete constructions. The change in measurement methodology resulted in possibility of measuring the thickness of the rocks above the tunnels as well as thickness of a singular rock layer. The idea is to find two resonance frequencies of the self-exited system, which consists of a vibration exciter and vibration receiver placed at a distance, which are coupled with a proper power amplifier, and which operate in a closed loop with a positive feedback. The resonance with the higher amplitude determines thickness of the whole rock, whereas the lower amplitude resonance indicates thickness of a singular layer. The results of the laboratory tests conducted on a group of different rock materials are also presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=auto-oscillator" title="auto-oscillator">auto-oscillator</a>, <a href="https://publications.waset.org/abstracts/search?q=non-destructive%20testing" title=" non-destructive testing"> non-destructive testing</a>, <a href="https://publications.waset.org/abstracts/search?q=rock%20thickness%20measurement" title=" rock thickness measurement"> rock thickness measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=geotechnic" title=" geotechnic"> geotechnic</a> </p> <a href="https://publications.waset.org/abstracts/2627/rock-thickness-measurement-by-using-self-excited-acoustical-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2627.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">374</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">40</span> Leverage Effect for Volatility with Generalized Laplace Error</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farrukh%20Javed">Farrukh Javed</a>, <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Podg%C3%B3rski"> Krzysztof Podgórski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We propose a new model that accounts for the asymmetric response of volatility to positive ('good news') and negative ('bad news') shocks in economic time series the so-called leverage effect. In the past, asymmetric powers of errors in the conditionally heteroskedastic models have been used to capture this effect. Our model is using the gamma difference representation of the generalized Laplace distributions that efficiently models the asymmetry. It has one additional natural parameter, the shape, that is used instead of power in the asymmetric power models to capture the strength of a long-lasting effect of shocks. Some fundamental properties of the model are provided including the formula for covariances and an explicit form for the conditional distribution of 'bad' and 'good' news processes given the past the property that is important for the statistical fitting of the model.

Especially meaningful in helicopter aviation is infrared emission by exhaust gases, regressed to the surroundings. Due to high temperature, exhaust gases are a major factor in detectability of a helicopter performing air combat operations. This study presents the results of simulating the flow of the mixture of exhaust and air in the flow duct of an injective exhaust cooler, adapted to cooperate with the PZL 10W turbine engine. The simulation was performed using a numerical model and the ANSYS Fluent software. Simulation computations were conducted for set flight conditions of the PZL W-3 Falcon helicopter. The conclusions resulting from the conducted numerical computations should allow for optimisation of the flow duct geometry in the cooler, in order to achieve the greatest possible temperature reduction of exhaust exiting into the surroundings. It is expected that the obtained results should be useful for further works related to the development of the final version of exhaust cooler for the PZL W-3 Falcon helicopter. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=exhaust%20cooler" title="exhaust cooler">exhaust cooler</a>, <a href="https://publications.waset.org/abstracts/search?q=helicopter" title=" helicopter"> helicopter</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulation" title=" numerical simulation"> numerical simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=stealth" title=" stealth"> stealth</a> </p> <a href="https://publications.waset.org/abstracts/106682/numerical-simulation-of-air-flow-exhaust-and-their-mixture-in-a-helicopter-exhaust-injective-cooler" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106682.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">150</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">38</span> Posttranslational Modifications of Histone H3 in Tumor Tissue Isolated from Silver and Gold Nanoparticles Treated Mice</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lucyna%20Kapka-Skrzypczak">Lucyna Kapka-Skrzypczak</a>, <a href="https://publications.waset.org/abstracts/search?q=Barbara%20Sochanowicz"> Barbara Sochanowicz</a>, <a href="https://publications.waset.org/abstracts/search?q=Magdalena%20Matysiak-Kucharek"> Magdalena Matysiak-Kucharek</a>, <a href="https://publications.waset.org/abstracts/search?q=Magdalena%20Czajka"> Magdalena Czajka</a>, <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Sawicki"> Krzysztof Sawicki</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcin%20Kruszewski"> Marcin Kruszewski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the strong antimicrobial activity silver nanoparticles (AgNPs) are widely used in various medical and general applications, among others, in cosmetics, odour resistant textiles, etc. The aim of this study was to compare effect of AgNPs and gold NPs (AuNPs) on histones posttranslational modifications. Histone molecule posttranscriptional modifications are responsible for chromatin compaction and repackaging. In this study, BALB/c mice were inoculated with murine mammary carcinoma 4T1 cells and treated with AgNPs coated with citrate (AgNPs(cit) or PEG (AgNPs(PEG), or AuNPs. Thereafter the histone H3 acetylation on Lys9 and H3 methylation on Lys4, Lys9, Lys29 was investigated. All NPs tested decreased H3 methylation, while no effect was observed for H3 acetylation. Modification of histone H3 methylation dependent on type of NPs used its coating, site of methylation and treatment used. Conclusion, epigenetic effects of nanomaterials depend on nanomaterial composition, its coating, and way of application.

BED is characterized by a loss of control over the quantity of food consumed and the lack of the compensatory behaviors, such as induced vomiting or purging. Studies highlight that certain personality traits may contribute to the severity of symptoms in the ED. The aim of this study is to analyze the relationship between psychological variables (Impulsivity and Urgency) and Nutritional restrictions in BED. The study included two groups. The first group consisted of 35 women with BED aged 18 to 28. The control group - 35 women without ED aged 18 to 28. ED-1 questionnaire was used in a study to assess the severity of impulsivity, urgency and nutritional restrictions. The obtained data were standardized. Statistical analyzes were performed using SPSS 21 software. The severity of impulsivity was higher in patients with BED than the control group. The relation between impulsivity and nutritional restrictions in BED was observed, only taking into consideration the relationship of these variables with the level of urgency. However, if the severity of urgency in this relationship is skipped, the relationship between impulsivity and nutritional restrictions will not occur. Impulsivity has a negative relationship with the level of urgency. This study suggests the need to analyze the interaction between impulsivity and urgency, and their relationship with dietary behavior in BED, especially nutritional restrictions. Analysis of single isolated features may give erroneous results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=binge%20eating%20disorder" title="binge eating disorder">binge eating disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=impulsivity" title=" impulsivity"> impulsivity</a>, <a href="https://publications.waset.org/abstracts/search?q=nutritional%20restrictions" title=" nutritional restrictions"> nutritional restrictions</a>, <a href="https://publications.waset.org/abstracts/search?q=urgency" title=" urgency"> urgency</a> </p> <a href="https://publications.waset.org/abstracts/27885/impulsivity-and-nutritional-restrictions-in-bed" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27885.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">469</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">36</span> Numerical and Experimental Investigation of a Mechanical System with a Pendulum</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andrzej%20Mitura">Andrzej Mitura</a>, <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Kecik"> Krzysztof Kecik</a>, <a href="https://publications.waset.org/abstracts/search?q=Michal%20Augustyniak"> Michal Augustyniak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a numerical and experimental research of a nonlinear two degrees of freedom system. The tested system consists of a mechanical oscillator (the primary subsystem) with the attached pendulum (the secondary subsystem). The oscillator is suspended on a linear (or nonlinear) coil spring and a nonlinear magnetorheorogical damper and it is excited kinematically. Added pendulum can be used to reduce vibration of a primary subsystem or to energy harvesting. The numerical and experimental investigations showed that the pendulum can perform several types of motion, for example: chaotic motion, constant position in lower or upper (stable inverted pendulum), rotation, symmetrical or asymmetrical swinging vibrations. The main objective of this study is to determine an influence of system parameters for increasing the zone when the pendulum rotates. As a final effect a semi-active control method to change the pendulum solution on the rotation is proposed. To the implementation of this method the magnetorheorogical damper is applied. Continuous rotation of the pendulum is desirable for recovery of energy.

This phenomenon is used, among others, for the production of liquid floor self-levelling compounds. Alumina cement is several times more expensive than Portland cement and is a component having a significant impact on prices of products manufactured with its use. For the production of liquid floor self-levelling compounds, low-alumina cement containing approximately 40% Al<sub>2</sub>O<sub>3 </sub>is normally used. The aim of the study was to determine the impact of Portland cement with the addition of alumina cement on the basic physical and mechanical properties of cement slurries and mortars. CEM I 42.5R and three types of alumina cement containing 40%, 50% and 70% of Al<sub>2</sub>O<sub>3</sub> were used for the tests. Mixes containing 4%, 6%, 8%, 10% and 12% of different varieties of alumina cement were prepared; for which, the time of initial and final setting, compressive and flexural strength and adhesion to concrete substrate were determined. The analysis of the obtained test results showed that a similar immediate setting effect and clearly better adhesion strength can be obtained using the addition of 6% of high-alumina cement than 12% of low-alumina cement. As the prices of these cements are similar, this can give significant financial savings in the production of liquid floor self-levelling compounds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alumina%20cement" title="alumina cement">alumina cement</a>, <a href="https://publications.waset.org/abstracts/search?q=immediate%20setting" title=" immediate setting"> immediate setting</a>, <a href="https://publications.waset.org/abstracts/search?q=compression%20strength" title=" compression strength"> compression strength</a>, <a href="https://publications.waset.org/abstracts/search?q=adhesion%20to%20substrate" title=" adhesion to substrate"> adhesion to substrate</a> </p> <a href="https://publications.waset.org/abstracts/118238/the-impact-of-alumina-cement-on-properties-of-portland-cement-slurries-and-mortars" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118238.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">152</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">34</span> PET Image Resolution Enhancement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Malczewski">Krzysztof Malczewski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> PET is widely applied scanning procedure in medical imaging based research. It delivers measurements of functioning in distinct areas of the human brain while the patient is comfortable, conscious and alert. This article presents the new compression sensing based super-resolution algorithm for improving the image resolution in clinical Positron Emission Tomography (PET) scanners. The issue of motion artifacts is well known in Positron Emission Tomography (PET) studies as its side effect. The PET images are being acquired over a limited period of time. As the patients cannot hold breath during the PET data gathering, spatial blurring and motion artefacts are the usual result. These may lead to wrong diagnosis. It is shown that the presented approach improves PET spatial resolution in cases when Compressed Sensing (CS) sequences are used. Compressed Sensing (CS) aims at signal and images reconstructing from significantly fewer measurements than were traditionally thought necessary. The application of CS to PET has the potential for significant scan time reductions, with visible benefits for patients and health care economics. In this study the goal is to combine super-resolution image enhancement algorithm with CS framework to achieve high resolution PET output. Both methods emphasize on maximizing image sparsity on known sparse transform domain and minimizing fidelity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PET" title="PET">PET</a>, <a href="https://publications.waset.org/abstracts/search?q=super-resolution" title=" super-resolution"> super-resolution</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20reconstruction" title=" image reconstruction"> image reconstruction</a>, <a href="https://publications.waset.org/abstracts/search?q=pattern%20recognition" title=" pattern recognition"> pattern recognition</a> </p> <a href="https://publications.waset.org/abstracts/6017/pet-image-resolution-enhancement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6017.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">372</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">33</span> CFD Simulation Research on a Double Diffuser for Wind Turbines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Skiba">Krzysztof Skiba</a>, <a href="https://publications.waset.org/abstracts/search?q=Zdzislaw%20Kaminski"> Zdzislaw Kaminski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wind power is based on a variety of construction solutions to convert wind energy into electrical energy. These constructions are constrained by the correlation between their energy conversion efficiency and the area they occupy. Their energy conversion efficiency can be improved by wind tunnel tests of a rotor as a diffuser to optimize shapes of aerodynamic elements, to adapt these elements to changing conditions and to increase airflow intensity. This paper discusses the results of computer simulations and aerodynamic analyzes of this innovative diffuser design. The research aims at determining the aerodynamic phenomena triggered by the airflow inside this construction, and developing a design to improve the efficiency of the wind turbine. The research results enable us to design a diffuser with a double Venturi nozzle and specially shaped blades. The design of this type uses Bernoulli’s law on the behavior of the flowing medium in the tunnel of a decreasing diameter. The air flowing along the tunnel changes its velocity so the rotor inside such a decreased tunnel diameter rotates faster in this airflow than does the wind outside this tunnel, which makes the turbine more efficient. Additionally, airflow velocity is improved by applying aerodynamic rings with extended trailing edges to achieve controlled turbulent vortices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wind%20turbine" title="wind turbine">wind turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title=" renewable energy"> renewable energy</a>, <a href="https://publications.waset.org/abstracts/search?q=cfd" title=" cfd"> cfd</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20analysis" title=" numerical analysis"> numerical analysis</a> </p> <a href="https://publications.waset.org/abstracts/50081/cfd-simulation-research-on-a-double-diffuser-for-wind-turbines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50081.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">310</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">32</span> Sportband: An Idea for Workout Monitoring in Amateur and Recreational Sports</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kamila%20Mazur-Oleszczuk">Kamila Mazur-Oleszczuk</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafal%20Banasiuk"> Rafal Banasiuk</a>, <a href="https://publications.waset.org/abstracts/search?q=Dawid%20Krasnowski"> Dawid Krasnowski</a>, <a href="https://publications.waset.org/abstracts/search?q=Maciej%20Pek"> Maciej Pek</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcin%20Podgorski"> Marcin Podgorski</a>, <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Rykaczewski"> Krzysztof Rykaczewski</a>, <a href="https://publications.waset.org/abstracts/search?q=Sabina%20Zoledowska"> Sabina Zoledowska</a>, <a href="https://publications.waset.org/abstracts/search?q=Dawid%20Nidzworski"> Dawid Nidzworski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Workout safety is one of the most significant challenges of recreational sports. Loss of water and electrolytes is a consequence of thermoregulatory sweating during exercise. The rate of sweat loss and its chemical composition can fluctuate within and among individuals. That is why we propose our sportband 'Flow' as a device for monitoring these parameters. 'Flow' consists of two parts: an intelligent module and a mobile application. The application allows verifying the training progress and data archiving. The sportband intelligent module includes temperature, heart rate and pulse measurement (non-invasive, continuous methods of workout monitoring). Apart from the standard components, the device will consist of a sweat composition analyzer situated in sportband intelligent module. Sweat is a water solution of numerous compounds such as ions (sodium up to 1609 µg/ml, potassium up to 274 µg/ml), lactic acid (skin pH is between 4.5 - 6) and a small amount of glucose. Awareness of sweat composition allows personalizing electrolyte intake after training. A comprehensive workout monitoring (sweat composition, heart rate, blood oxygen level) will provide improvement in the training routine and time management, which is our goal for the development of the sweat composition analyzer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flow" title="flow">flow</a>, <a href="https://publications.waset.org/abstracts/search?q=sportband" title=" sportband"> sportband</a>, <a href="https://publications.waset.org/abstracts/search?q=sweat" title=" sweat"> sweat</a>, <a href="https://publications.waset.org/abstracts/search?q=workout%20monitoring" title=" workout monitoring"> workout monitoring</a> </p> <a href="https://publications.waset.org/abstracts/112409/sportband-an-idea-for-workout-monitoring-in-amateur-and-recreational-sports" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112409.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">151</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">31</span> Dissimilar Welding Of New High Oxidation Material – Thor™ 115 With Vm-12 Shc</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michal%20Urzynicok">Michal Urzynicok</a>, <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Kwiecinski"> Krzysztof Kwiecinski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The development of materials used in the power generation industry for the production of boilers and their parts is characterized by high steam parameters, which present new challenges. Implementation of new combinations of alloying elements that lead to the best possible mechanical properties, including creep resistance, greatly affects new steels' weldability. All new grades have to undergo many different examinations, in regards to bending and welding, in order to enable the development of fabrication technologies, ensuring failure-free production and assembly of boiler components. 12% Cr martensitic steels like THOR™ 115 or VM-12 SHC are characterized by high oxidation resistance in high-temperature environments. At the moment, VM-12 SHC can be found in many boilers where both headers and superheater coils were produced. As this material is very difficult to obtain, a search for a proper replacement has begun. A new creep strength-enhanced ferritic steel for service in supercritical and ultra-supercritical boiler applications was developed by Tenaris in Italy and it is designated as Thor™115 (Tenaris High Oxidation Resistance). As high demand in power plants occurred to replace some parts of existing installations fabricated from VM12-SHC with other alternatives, a new development of welding procedures has begun to prepare fabricators for the challenges of joining old components with new THOR™ 115 material. This paper covers the first research of welding of dissimilar joints made out of VM12-SHC and THOR™ 115. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thor" title="thor">thor</a>, <a href="https://publications.waset.org/abstracts/search?q=vm12" title=" vm12"> vm12</a>, <a href="https://publications.waset.org/abstracts/search?q=dissimilar%20welding" title=" dissimilar welding"> dissimilar welding</a>, <a href="https://publications.waset.org/abstracts/search?q=weldability" title=" weldability"> weldability</a> </p> <a href="https://publications.waset.org/abstracts/134858/dissimilar-welding-of-new-high-oxidation-material-thor-115-with-vm-12-shc" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134858.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">153</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30</span> Poultry as a Carrier of Chlamydia gallinacea</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Monika%20Szyma%C5%84ska-Czerwi%C5%84sk">Monika Szymańska-Czerwińsk</a>, <a href="https://publications.waset.org/abstracts/search?q=Kinga%20Zar%C4%99ba-Marchewka"> Kinga Zaręba-Marchewka</a>, <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Niemczuk"> Krzysztof Niemczuk</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Chlamydiaceae are Gram-negative bacteria distributed worldwide in animals and humans. One of them is Chlamydia gallinacea recently discovered. Available data show that C. gallinacea is dominant chlamydial agent found in poultry in European and Asian countries. The aim of the studies was screening of poultry flocks in order to evaluate frequency of C. gallinacea shedding and genetic diversity. Sampling was conducted in different regions of Poland in 2019-2020. Overall, 1466 cloacal/oral swabs were collected in duplicate from 146 apparently healthy poultry flocks including chickens, turkeys, ducks, geese and quails. Dry swabs were used for DNA extraction. DNA extracts were screened using a Chlamydiaceae 23S rRNA real-time PCR assay. To identify Chlamydia species, specific real-time PCR assays were performed. Furthermore, selected samples were used for sequencing based on ompA gene fragments and variable domains (VD1-2, VD3-4). In total, 10.3% of the tested flocks were Chlamydiaceae-positive (15/146 farms). The presence of Chlamydiaceae was confirmed mainly in chickens (13/92 farms) but also in turkey (1/19 farms) and goose (1/26 farms) flocks. Eleven flocks were identified as C. gallinacea-positive while four flocks remained unclassified. Phylogenetic analysis revealed at least 16 genetic variants of C. gallinacea. Research showed that Chlamydiaceae occur in a poultry flock in Poland. The strains of C. gallinacea as dominant species show genetic variability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20gallinacea" title="C. gallinacea">C. gallinacea</a>, <a href="https://publications.waset.org/abstracts/search?q=emerging%20agent" title=" emerging agent"> emerging agent</a>, <a href="https://publications.waset.org/abstracts/search?q=poultry" title=" poultry"> poultry</a>, <a href="https://publications.waset.org/abstracts/search?q=real-time%20PCR" title=" real-time PCR"> real-time PCR</a> </p> <a href="https://publications.waset.org/abstracts/159255/poultry-as-a-carrier-of-chlamydia-gallinacea" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159255.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">105</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">29</span> Comparison of Physicochemical Properties of DNA-Ionic Liquids Complexes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ewelina%20Nowak">Ewelina Nowak</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20Wisla-Swider"> Anna Wisla-Swider</a>, <a href="https://publications.waset.org/abstracts/search?q=Gohar%20Khachatryan"> Gohar Khachatryan</a>, <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Danel"> Krzysztof Danel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Complexes of ionic liquids with different heterocyclic-rings were synthesized by ion exchange reactions with pure salmon DNA.

Patterns of UV-Vis, photoluminescence, IR, and CD spectra indicated inclusion of small molecules into DNA structure. Molecular weight and radii of gyrations values of ILs-DNA complexes chains were established by HPSEC–MALLS–RI method. Modification DNA with 1-ethyl-1-methylpyrrolidinium bromide gives more uniform material and leads to elimination of high molecular weight chains. Thus, the incorporation DNA double helical structure with both 1-hexyl-3-methylimidazolium chloride and 1-butyl-4-methylpyridinium chloride exhibited higher molecular weight values. Scanning electron microscopy images indicate formation of nanofibre structures in all DNA complexes. Fluorescence depends strongly on the environment in which the chromophores are inserted and simultaneously on the molecular interactions with the biopolymer matrix. The most intensive emission was observed for DNA-imidazole ring complex. Decrease in intensity UV-Vis peak absorption is a consequence of a reduction in the spatial order of polynucleotide strands and provides different π–π stacking structure. Changes in optical properties confirmed by spectroscopy methods make DNA-ILs complexes potential biosensor applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biopolymers" title="biopolymers">biopolymers</a>, <a href="https://publications.waset.org/abstracts/search?q=biosensors" title=" biosensors"> biosensors</a>, <a href="https://publications.waset.org/abstracts/search?q=cationic%20surfactant" title=" cationic surfactant"> cationic surfactant</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA" title=" DNA"> DNA</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA-gels" title=" DNA-gels"> DNA-gels</a> </p> <a href="https://publications.waset.org/abstracts/85125/comparison-of-physicochemical-properties-of-dna-ionic-liquids-complexes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85125.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">183</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> Amine Hardeners with Carbon Nanotubes Dispersing Ability for Epoxy Coating Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Szymon%20Kugler">Szymon Kugler</a>, <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Kowalczyk"> Krzysztof Kowalczyk</a>, <a href="https://publications.waset.org/abstracts/search?q=Tadeusz%20Spychaj"> Tadeusz Spychaj</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An addition of carbon nanotubes (CNT) can simultaneously improve many features of epoxy coatings, i.e. electrical, mechanical, functional and thermal. Unfortunately, this nanofiller negatively affects visual properties of the coatings, such as transparency and gloss. The main reason for the low visual performance of CNT-modified epoxy coatings is the lack of compatibility between CNT and popular amine curing agents, although epoxy resins based on bisphenol A are indisputable good CNT dispersants. This is a serious obstacle in utilization of the coatings in advanced applications, demanding both high transparency and electrical conductivity. The aim of performed investigations was to find amine curing agents exhibiting affinity for CNT, and ensuring good performance of epoxy coatings with them. Commercially available CNT was dispersed in epoxy resin, as well as in different aliphatic, cycloaliphatic and aromatic amines, using one of two dispergation methods: ultrasonic or mechanical. The CNT dispersions were subsequently used in the preparation of epoxy coating compositions and coatings on a transparent substrate. It was found that amine derivative of bio-based cardanol, as well as modified o-tolylbiguanide exhibit significant CNT, dispersing properties, resulting in improved transparent/electroconductive performance of epoxy coatings. In one of prepared coating systems just 0.025 wt.% (250 ppm) of CNT was enough to obtain coatings with semi conductive properties, 83% of transparency as well as perfect chemical resistance to methyl-ethyl ketone and improved thermal stability. Additionally, a theory of the influence of amine chemical structure on CNT dispersing properties was proposed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bio-based%20cardanol" title="bio-based cardanol">bio-based cardanol</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20nanotubes" title=" carbon nanotubes"> carbon nanotubes</a>, <a href="https://publications.waset.org/abstracts/search?q=epoxy%20coatings" title=" epoxy coatings"> epoxy coatings</a>, <a href="https://publications.waset.org/abstracts/search?q=tolylbiguanide" title=" tolylbiguanide"> tolylbiguanide</a> </p> <a href="https://publications.waset.org/abstracts/74761/amine-hardeners-with-carbon-nanotubes-dispersing-ability-for-epoxy-coating-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74761.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">211</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> Transformation of Positron Emission Tomography Raw Data into Images for Classification Using Convolutional Neural Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pawe%C5%82%20Konieczka">Paweł Konieczka</a>, <a href="https://publications.waset.org/abstracts/search?q=Lech%20Raczy%C5%84ski"> Lech Raczyński</a>, <a href="https://publications.waset.org/abstracts/search?q=Wojciech%20Wi%C5%9Blicki"> Wojciech Wiślicki</a>, <a href="https://publications.waset.org/abstracts/search?q=Oleksandr%20Fedoruk"> Oleksandr Fedoruk</a>, <a href="https://publications.waset.org/abstracts/search?q=Konrad%20Klimaszewski"> Konrad Klimaszewski</a>, <a href="https://publications.waset.org/abstracts/search?q=Przemys%C5%82aw%20Kopka"> Przemysław Kopka</a>, <a href="https://publications.waset.org/abstracts/search?q=Wojciech%20Krzemie%C5%84"> Wojciech Krzemień</a>, <a href="https://publications.waset.org/abstracts/search?q=Roman%20Shopa"> Roman Shopa</a>, <a href="https://publications.waset.org/abstracts/search?q=Jakub%20Baran"> Jakub Baran</a>, <a href="https://publications.waset.org/abstracts/search?q=Aur%C3%A9lien%20Coussat"> Aurélien Coussat</a>, <a href="https://publications.waset.org/abstracts/search?q=Neha%20Chug"> Neha Chug</a>, <a href="https://publications.waset.org/abstracts/search?q=Catalina%20Curceanu"> Catalina Curceanu</a>, <a href="https://publications.waset.org/abstracts/search?q=Eryk%20Czerwi%C5%84ski"> Eryk Czerwiński</a>, <a href="https://publications.waset.org/abstracts/search?q=Meysam%20Dadgar"> Meysam Dadgar</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamil%20Dulski"> Kamil Dulski</a>, <a href="https://publications.waset.org/abstracts/search?q=Aleksander%20Gajos"> Aleksander Gajos</a>, <a href="https://publications.waset.org/abstracts/search?q=Beatrix%20C.%20Hiesmayr"> Beatrix C.

In positron emission tomography (PET) studies, CNN may be applied directly to the reconstructed distribution of radioactive tracers injected into the patient's body, as a pattern recognition tool. Nonetheless, much PET data still exists in non-image format and this fact opens a question on whether they can be used for training CNN. In this contribution, the main focus of this paper is the problem of processing vectors with a small number of features in comparison to the number of pixels in the output images. The proposed methodology was applied to the classification of PET coincidence events. <p class="card-text"><strong>Keywords:</strong> <a
