Examples are storage of solar energy, cold, and space heating/cooling of buildings. During a phase change, the enthalpy vs. temperature plot of PCMs shows a jump and there is a distinct peak in the heat capacity plot. We present a theoretical description from which these jumps and peaks can be obtained. We apply our theoretical results to fit experimental data with very good accuracy for selected materials and changes between two phases. The development is based on the observation that PCMs are polycrystalline; i.e., composed of many single-crystalline grains. The enthalpy and heat capacity are thus interpreted as averages of the contributions from the individual grains. We also show how to determine the baseline and excess part of the heat capacity and thus the latent heat corresponding to the phase change. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=averaging" title="averaging">averaging</a>, <a href="https://publications.waset.org/abstracts/search?q=enthalpy%20jump" title=" enthalpy jump"> enthalpy jump</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20capacity%20peak" title=" heat capacity peak"> heat capacity peak</a>, <a href="https://publications.waset.org/abstracts/search?q=phase%20change" title=" phase change"> phase change</a> </p> <a href="https://publications.waset.org/abstracts/62362/modeling-of-enthalpy-and-heat-capacity-of-phase-change-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62362.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">459</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> A Regional Analysis on Co-movement of Sovereign Credit Risk and Interbank Risks </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Janbaz">Mehdi Janbaz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The global financial crisis and the credit crunch that followed magnified the importance of credit risk management and its crucial role in the stability of all financial sectors and the whole of the system. Many believe that risks faced by the sovereign sector are highly interconnected with banking risks and most likely to trigger and reinforce each other. This study aims to examine (1) the impact of banking and interbank risk factors on the sovereign credit risk of Eurozone, and (2) how the EU Credit Default Swaps spreads dynamics are affected by the Crude Oil price fluctuations. The hypothesizes are tested by employing fitting risk measures and through a four-staged linear modeling approach. The sovereign senior 5-year Credit Default Swap spreads are used as a core measure of the credit risk. The monthly time-series data of the variables used in the study are gathered from the DataStream database for a period of 2008-2019. First, a linear model test the impact of regional macroeconomic and market-based factors (STOXX, VSTOXX, Oil, Sovereign Debt, and Slope) on the CDS spreads dynamics. Second, the bank-specific factors, including LIBOR-OIS spread (the difference between the Euro 3-month LIBOR rate and Euro 3-month overnight index swap rates) and Euribor, are added to the most significant factors of the previous model. Third, the global financial factors including EURO to USD Foreign Exchange Volatility, TED spread (the difference between 3-month T-bill and the 3-month LIBOR rate based in US dollars), and Chicago Board Options Exchange (CBOE) Crude Oil Volatility Index are added to the major significant factors of the first two models. Finally, a model is generated by a combination of the major factor of each variable set in addition to the crisis dummy. The findings show that (1) the explanatory power of LIBOR-OIS on the sovereign CDS spread of Eurozone is very significant, and (2) there is a meaningful adverse co-movement between the Crude Oil price and CDS price of Eurozone. Surprisingly, adding TED spread (the difference between the three-month Treasury bill and the three-month LIBOR based in US dollars.) to the analysis and beside the LIBOR-OIS spread (the difference between the Euro 3M LIBOR and Euro 3M OIS) in third and fourth models has been increased the predicting power of LIBOR-OIS. Based on the results, LIBOR-OIS, Stoxx, TED spread, Slope, Oil price, OVX, FX volatility, and Euribor are the determinants of CDS spreads dynamics in Eurozone. Moreover, the positive impact of the crisis period on the creditworthiness of the Eurozone is meaningful. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CDS" title="CDS">CDS</a>, <a href="https://publications.waset.org/abstracts/search?q=crude%20oil" title=" crude oil"> crude oil</a>, <a href="https://publications.waset.org/abstracts/search?q=interbank%20risk" title=" interbank risk"> interbank risk</a>, <a href="https://publications.waset.org/abstracts/search?q=LIBOR-OIS" title=" LIBOR-OIS"> LIBOR-OIS</a>, <a href="https://publications.waset.org/abstracts/search?q=OVX" title=" OVX"> OVX</a>, <a href="https://publications.waset.org/abstracts/search?q=sovereign%20credit%20risk" title=" sovereign credit risk"> sovereign credit risk</a>, <a href="https://publications.waset.org/abstracts/search?q=TED" title=" TED"> TED</a> </p> <a href="https://publications.waset.org/abstracts/124806/a-regional-analysis-on-co-movement-of-sovereign-credit-risk-and-interbank-risks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124806.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">11</span> Valuation of Caps and Floors in a LIBOR Market Model with Markov Jump Risks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shih-Kuei%20Lin">Shih-Kuei Lin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The characterization of the arbitrage-free dynamics of interest rates is developed in this study under the presence of Markov jump risks, when the term structure of the interest rates is modeled through simple forward rates. We consider Markov jump risks by allowing randomness in jump sizes, independence between jump sizes and jump times. The Markov jump diffusion model is used to capture empirical phenomena and to accurately describe interest jump risks in a financial market. We derive the arbitrage-free model of simple forward rates under the spot measure. Moreover, the analytical pricing formulas for a cap and a floor are derived under the forward measure when the jump size follows a lognormal distribution. In our empirical analysis, we find that the LIBOR market model with Markov jump risk better accounts for changes from/to different states and different rates. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=arbitrage-free" title="arbitrage-free">arbitrage-free</a>, <a href="https://publications.waset.org/abstracts/search?q=cap%20and%20floor" title=" cap and floor"> cap and floor</a>, <a href="https://publications.waset.org/abstracts/search?q=Markov%20jump%20diffusion%20model" title=" Markov jump diffusion model"> Markov jump diffusion model</a>, <a href="https://publications.waset.org/abstracts/search?q=simple%20forward%20rate%20model" title=" simple forward rate model"> simple forward rate model</a>, <a href="https://publications.waset.org/abstracts/search?q=volatility%20smile" title=" volatility smile"> volatility smile</a>, <a href="https://publications.waset.org/abstracts/search?q=EM%20algorithm" title=" EM algorithm"> EM algorithm</a> </p> <a href="https://publications.waset.org/abstracts/11690/valuation-of-caps-and-floors-in-a-libor-market-model-with-markov-jump-risks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11690.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">421</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> iPAD as a Communication Tool for Disabled Seniors: A Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vojt%C4%9Bch%20Gybas">Vojtěch Gybas</a>, <a href="https://publications.waset.org/abstracts/search?q=Libor%20Klubal"> Libor Klubal</a>, <a href="https://publications.waset.org/abstracts/search?q=Kate%C5%99ina%20Kostol%C3%A1nyov%C3%A1"> Kateřina Kostolányová</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This case study responds to the current trends in ICT.

In particular, the attention was paid to the effects of non-standard monetary policy tools for financial markets. However, the empirical evidence about their effects and real consequences for the financial markets are still not final. The main aim of the study is to survey the consequences of standard and non-standard monetary policy instruments, implemented during the global financial crisis in the United States, United Kingdom and Euroland, with particular attention to the results for the stabilization of global financial markets. The study analyses the consequences for short and long-term market interest rates, interbank interest rates and LIBOR-OIS spread. The study consists mainly of the empirical review, indicating the impact of the implementation of these tools for the financial markets. The following research methods were used in the study: literature studies, including domestic and foreign literature, cause and effect analysis and statistical analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asset%20purchase%20facility" title="asset purchase facility">asset purchase facility</a>, <a href="https://publications.waset.org/abstracts/search?q=consequences%20of%20monetary%20policy%20instruments" title=" consequences of monetary policy instruments"> consequences of monetary policy instruments</a>, <a href="https://publications.waset.org/abstracts/search?q=non-standard%20monetary%20policy" title=" non-standard monetary policy"> non-standard monetary policy</a>, <a href="https://publications.waset.org/abstracts/search?q=quantitative%20easing" title=" quantitative easing"> quantitative easing</a> </p> <a href="https://publications.waset.org/abstracts/15292/non-standard-monetary-policy-measures-and-their-consequences" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15292.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">331</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">7</span> Synthesis of Flower-Like Silver Nanoarchitectures in Special Shapes and Their Applications in Surface-Enhanced Raman Scattering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Radka%20Kr%C3%A1lov%C3%A1">Radka Králová</a>, <a href="https://publications.waset.org/abstracts/search?q=Libor%20Kv%C3%ADtek"> Libor Kvítek</a>, <a href="https://publications.waset.org/abstracts/search?q=V%C3%A1clav%20Ranc"> Václav Ranc</a>, <a href="https://publications.waset.org/abstracts/search?q=Ale%C5%A1%20Pan%C3%A1%C4%8Dek"> Aleš Panáček</a>, <a href="https://publications.waset.org/abstracts/search?q=Radek%20Zbo%C5%99il"> Radek Zbořil</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Surface–Enhanced Raman Scattering (SERS) is an optical spectroscopic technique with very good potential for sensitive detection of substances. In this research, active substrates with high enhancement were provided. Novel silver particles (nanostructures) with high roughened, flower–like morphology were prepared by reduction of cation complex [Ag(NH3)2]+ in presence of sodium borohydride as reducing agent and stabilized polyacrylic acid. The products were characterized by UV/VIS absorption spectrophotometry. Special shapes of silver particles were determined by scanning electron microscopy (SEM) and transmission electron spectroscopy (TEM). Dispersions of this particle were put on fixed substrate to producing suitable layer for SERS. Adenine was applied as basic substance whose effect of enhancement on the layer of silver nanostructures was studied. By comparison with our work, the important influence of stabilizers, polyacrylic acid with various molecular weight and concentration, on the transfer of particles and formation of new structure was confirmed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=metals" title="metals">metals</a>, <a href="https://publications.waset.org/abstracts/search?q=nanostructures" title=" nanostructures"> nanostructures</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20reduction" title=" chemical reduction"> chemical reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=Raman%20spectroscopy" title=" Raman spectroscopy"> Raman spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20properties" title=" optical properties "> optical properties </a> </p> <a href="https://publications.waset.org/abstracts/11710/synthesis-of-flower-like-silver-nanoarchitectures-in-special-shapes-and-their-applications-in-surface-enhanced-raman-scattering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11710.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">370</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">6</span> Utilization of Multi-Criteria Evaluation in Forensic Engineering and the Expertise outside Wall Subsystem</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tomas%20Barnak">Tomas Barnak</a>, <a href="https://publications.waset.org/abstracts/search?q=Libor%20Matejka"> Libor Matejka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study is to create a standard application using multi-criteria evaluation in the field of forensic engineering. This situation can occur in the professional assessment in several cases such as when it is necessary to consider more criteria variant of the structural subsystems, more variants according to several criteria based on a court claim, which requires expert advice. A problematic situation arises when it is necessary to clearly determine the ranking of the options according to established criteria, and reduce subjective evaluation. For the procurement in the field of construction which is based on the prepared text of the law not only economic criteria but also technical, technological and environmental criteria will be determined. This fact substantially changes the style of evaluation of individual bids. For the above-mentioned needs of procurement, the unification of expert’s decisions and the use of multi-criteria assessment seem to be a reasonable option. In the case of experimental verification when using multi-criteria evaluation of alternatives construction subsystem the economic, technical, technological and environmental criteria will be compared. The core of the solution is to compare a selected number of set criteria, application methods and evaluation weighting based on the weighted values assigned to each of the criteria to use multi-criteria evaluation methods. The sequence of individual variations is determined by the evaluation of the importance of the values of corresponding criteria concerning expertise in the problematic of outside wall constructional subsystems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=criteria" title="criteria">criteria</a>, <a href="https://publications.waset.org/abstracts/search?q=expertise" title=" expertise"> expertise</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-criteria%20evaluation" title=" multi-criteria evaluation"> multi-criteria evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=outside%20wall%20subsystems" title=" outside wall subsystems"> outside wall subsystems</a> </p> <a href="https://publications.waset.org/abstracts/47490/utilization-of-multi-criteria-evaluation-in-forensic-engineering-and-the-expertise-outside-wall-subsystem" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47490.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">330</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> Assisted Approach as a Tool for Increasing Attention When Using the iPad in a Special Elementary School: Action Research</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vojt%C4%9Bch%20Gybas">Vojtěch Gybas</a>, <a href="https://publications.waset.org/abstracts/search?q=Libor%20Klubal"> Libor Klubal</a>, <a href="https://publications.waset.org/abstracts/search?q=Kate%C5%99ina%20Kostol%C3%A1nyov%C3%A1"> Kateřina Kostolányová</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, mobile touch technologies, such as tablets, are an integral part of teaching and learning in many special elementary schools. Many special education teachers tend to choose an iPad tablet with iOS. The reason is simple; the iPad has a function for pupils with special educational needs. If we decide to use tablets in teaching, in general, first we should try to stimulate the cognitive abilities of the pupil at the highest level, while holding the pupil’s attention on the task, when working with the device. This paper will describe how student attention can be increased by eliminating the working environment of selected applications, while using iPads with pupils in a special elementary school. Assisted function approach is highly effective at eliminating unwanted touching by a pupil when working on the desktop iPad, thus actively increasing the pupil´s attention while working on specific educational applications. During the various stages of the action, the research was conducted via data collection and interpretation. After a phase of gaining results and ideas for practice and actions, we carried out the check measurement, this time using the tool-assisted approach. In both cases, the pupils worked in the Math Board application and the resulting differences were evident. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=special%20elementary%20school" title="special elementary school">special elementary school</a>, <a href="https://publications.waset.org/abstracts/search?q=a%20mobile%20touch%20device" title=" a mobile touch device"> a mobile touch device</a>, <a href="https://publications.waset.org/abstracts/search?q=iPad" title=" iPad"> iPad</a>, <a href="https://publications.waset.org/abstracts/search?q=attention" title=" attention"> attention</a>, <a href="https://publications.waset.org/abstracts/search?q=Math%20Board" title=" Math Board"> Math Board</a> </p> <a href="https://publications.waset.org/abstracts/60753/assisted-approach-as-a-tool-for-increasing-attention-when-using-the-ipad-in-a-special-elementary-school-action-research" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60753.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">254</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">4</span> Individualized Teaching Process for Pupils with Moderate Mental Disability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vojt%C4%9BCh%20Gybas">VojtěCh Gybas</a>, <a href="https://publications.waset.org/abstracts/search?q=Libor%20Klubal"> Libor Klubal</a>, <a href="https://publications.waset.org/abstracts/search?q=Kate%C5%99Ina%20Kostol%C3%A1Nyov%C3%A1"> KateřIna KostoláNyová</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Individualized teaching process for pupils with moderate mental disabilities with the help of using mobile touch devices may be one of the forms of teaching to achieve better development of these students during the teaching process. Didactics of information and communication technology (ICT) for special primary schools, where within the Czech Republic pupils with moderate mental retardation are educated, is not precisely and clearly defined. Still, general educational program for elementary school contains a special educational area of information and communication technology, in which the work and content area are focused on work with the classic desktop, and it is not always acceptable in the case of students with moderate mental disabilities. Individualization of their schooling requires a fully elaborate content of teaching material corresponding with intellectual abilities and individuality of each pupil. After three years of daily use of mobile touch devices iPad and participant observation of 7 pupils in a class from special elementary school, we can say that these technologies can be a very useful tool, and in many ways, they even exceed, compensate and replace freely available printed educational material that is rather outdated. By working with mobile touch technology, a pupil gains responsibility, trains his will, learns to rely on himself. The first results obtained from the case studies suggest that this form of teaching may also be beneficial for pupils with moderate mental disabilities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=individualized%20teaching" title="individualized teaching">individualized teaching</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20touch%20technology" title=" mobile touch technology"> mobile touch technology</a>, <a href="https://publications.waset.org/abstracts/search?q=iPad" title=" iPad"> iPad</a>, <a href="https://publications.waset.org/abstracts/search?q=moderate%20mental%20disability" title=" moderate mental disability"> moderate mental disability</a>, <a href="https://publications.waset.org/abstracts/search?q=special%20education%20needs" title=" special education needs"> special education needs</a> </p> <a href="https://publications.waset.org/abstracts/53321/individualized-teaching-process-for-pupils-with-moderate-mental-disability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53321.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">328</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">3</span> Rate of Profit as a Pricing Benchmark in Islamic Banking to Create Financial Stability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Trisiladi%20Supriyanto">Trisiladi Supriyanto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although much research has been done on the pricing benchmark both in terms of fiqh or Islamic economic perspective, but no substitution for the concept of interest (rate of interest) up to now in the application of Islamic Banking because some of the jurists from the middle east even allow the use of a benchmark rate such as LIBOR (London Interbank Offered Rate) as a measure of Islamic financial asset prices, so in other words, they equate the concept of rate of interest with the concept of rate of profit, which is the core reason (raison detre) for the replacement of usury as instructed in the Quran. This study aims to find the concept of rate of profit on Islamic banking that can create economic justice and stability in Islamic Banking and Capital market. Rate of profit that creates economic justice and stability can be achieved through its role in maintaining the stability of the financial system in which there is an equitable distribution of income and wealth. To determine the role of the rate of profit as the basis of the sharing system implemented in the Islamic financial system, we can see the connection of rate of profit in creating financial stability, especially in the asset-liability management of financial institutions that generate a stable net margin or the rate of profit that is not affected by the ups and downs of the market risk factors including indirect effect on interest rates. Furthermore, Islamic financial stability can be seen from the role of the rate of profit on the stability of the Islamic financial assets that are measured from the Islamic financial asset price volatility in Islamic Bond Market in Capital Market. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rate%20of%20profit" title="Rate of profit">Rate of profit</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20justice" title=" economic justice"> economic justice</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a>, <a href="https://publications.waset.org/abstracts/search?q=equitable%20distribution%20of%20income" title=" equitable distribution of income"> equitable distribution of income</a>, <a href="https://publications.waset.org/abstracts/search?q=equitable%20distribution%20of%20wealth" title=" equitable distribution of wealth"> equitable distribution of wealth</a> </p> <a href="https://publications.waset.org/abstracts/48782/rate-of-profit-as-a-pricing-benchmark-in-islamic-banking-to-create-financial-stability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48782.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">403</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">2</span> Effects of Drought on Microbial Activity in Rhizosphere, Soil Hydrophobicity and Leaching of Mineral Nitrogen from Arable Soil Depending on Method of Fertilization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jakub%20Elbl">Jakub Elbl</a>, <a href="https://publications.waset.org/abstracts/search?q=Luk%C3%A1%C5%A1%20Plo%C5%A1ek"> Lukáš Plošek</a>, <a href="https://publications.waset.org/abstracts/search?q=Anton%C3%ADn%20Kintl"> Antonín Kintl</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaroslav%20Hyn%C5%A1t"> Jaroslav Hynšt</a>, <a href="https://publications.waset.org/abstracts/search?q=So%C5%88a%20Javorekov%C3%A1"> Soňa Javoreková</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaroslav%20Z%C3%A1hora"> Jaroslav Záhora</a>, <a href="https://publications.waset.org/abstracts/search?q=Libor%20Kalhotka"> Libor Kalhotka</a>, <a href="https://publications.waset.org/abstracts/search?q=Olga%20Urb%C3%A1nkov%C3%A1"> Olga Urbánková</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivana%20Charousov%C3%A1"> Ivana Charousová </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work presents the first results from the long-term laboratory experiment dealing with impact of drought on soil properties. Three groups of the treatment (A, B and C) with different regime of irrigation were prepared. The soil water content was maintained at 70 % of soil water holding capacity in group A, at 40 % in group B. In group C, soil water regime was maintained in the range of wilting point. Each group of the experiment was divided into three variants (A1 = B1, C1; A2 = B2, C2 etc.) with three repetitions: Variants A1 (B1, C1) were controls without addition of another fertilizer. Variants A2 (B2, C2) were fertilized with mineral nitrogen fertilizer DAM 390 (0.140 Mg of N per ha) and variants A3 (B3, C3) contained 45 g of Cp per a pot. The significant differences (ANOVA, P<0.05) in the leaching of mineral nitrogen and values of saturated hydraulic conductivity (Ksat) were found. The highest values of Ksat were found in variants (within each group) with addition of compost (A3, B3, C3). Conversely, the lowest values of Ksat were found in variants with addition of mineral nitrogen. Low values of Ksat indicate an increased level of hydrophobicity in individual groups of the experiment. Moreover, all variants with compost addition showed lower amount of mineral nitrogen leaching and high level of microbial activity than variants without. This decrease of mineral nitrogen leaching was about 200 % in comparison with the control variant and about 300 % with variant, where mineral nitrogen was added. Based on these results, we can conclude that changes of soil water content directly have impact on microbial activity, soil hydrophobicity and loss of mineral nitrogen from the soil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drought" title="drought">drought</a>, <a href="https://publications.waset.org/abstracts/search?q=microbial%20activity" title=" microbial activity"> microbial activity</a>, <a href="https://publications.waset.org/abstracts/search?q=mineral%20nitrogen" title=" mineral nitrogen"> mineral nitrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20hydrophobicity" title=" soil hydrophobicity"> soil hydrophobicity</a> </p> <a href="https://publications.waset.org/abstracts/7657/effects-of-drought-on-microbial-activity-in-rhizosphere-soil-hydrophobicity-and-leaching-of-mineral-nitrogen-from-arable-soil-depending-on-method-of-fertilization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7657.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">383</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">1</span> Leveraging xAPI in a Corporate e-Learning Environment to Facilitate the Tracking, Modelling, and Predictive Analysis of Learner Behaviour</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Libor%20Zachoval">Libor Zachoval</a>, <a href="https://publications.waset.org/abstracts/search?q=Daire%20O%20Broin"> Daire O Broin</a>, <a href="https://publications.waset.org/abstracts/search?q=Oisin%20Cawley"> Oisin Cawley</a> </p> <p class="card-text"><strong>Abstract:</strong></p> E-learning platforms, such as Blackboard have two major shortcomings: limited data capture as a result of the limitations of SCORM (Shareable Content Object Reference Model), and lack of incorporation of Artificial Intelligence (AI) and machine learning algorithms which could lead to better course adaptations. With the recent development of Experience Application Programming Interface (xAPI), a large amount of additional types of data can be captured and that opens a window of possibilities from which online education can benefit. In a corporate setting, where companies invest billions on the learning and development of their employees, some learner behaviours can be troublesome for they can hinder the knowledge development of a learner. Behaviours that hinder the knowledge development also raise ambiguity about learner’s knowledge mastery, specifically those related to gaming the system. Furthermore, a company receives little benefit from their investment if employees are passing courses without possessing the required knowledge and potential compliance risks may arise. Using xAPI and rules derived from a state-of-the-art review, we identified three learner behaviours, primarily related to guessing, in a corporate compliance course. The identified behaviours are: trying each option for a question, specifically for multiple-choice questions; selecting a single option for all the questions on the test; and continuously repeating tests upon failing as opposed to going over the learning material. These behaviours were detected on learners who repeated the test at least 4 times before passing the course. These findings suggest that gauging the mastery of a learner from multiple-choice questions test scores alone is a naive approach. Thus, next steps will consider the incorporation of additional data points, knowledge estimation models to model knowledge mastery of a learner more accurately, and analysis of the data for correlations between knowledge development and identified learner behaviours. Additional work could explore how learner behaviours could be utilised to make changes to a course. For example, course content may require modifications (certain sections of learning material may be shown to not be helpful to many learners to master the learning outcomes aimed at) or course design (such as the type and duration of feedback). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title="artificial
