class="card-text"><strong>Abstract:</strong></p> Natural sciences provide a wide range of experimental data whose related problems require study and modeling beyond the capabilities of conventional methodologies. Such problems have solution spaces whose complexity and high dimensionality require correspondingly complex regression methods for proper characterization. In this context, we propose an optimization method which consists in a hybrid dual optimizer setup: a global optimizer based on a modified variant of the popular Imperialist Competitive Algorithm (ICA), and a local optimizer based on a gradient descent approach. The ICA is modified such that intermediate solution populations are more quickly and efficiently pruned of low-fitness individuals by appropriately altering the assimilation, revolution and competition phases, which, combined with an initialization strategy based on low-discrepancy sampling, allows for a more effective exploration of the corresponding solution space. Subsequently, gradient-based optimization is used locally to seek the optimal solution in the neighborhoods of the solutions found through the modified ICA. We use this combined approach to find the optimal configuration and weights of a fully-connected neural network, resulting in regression models used to characterize the process of obtained bricks using silicon-based materials. Installations in the raw ceramics industry, i.e., bricks, are characterized by significant energy consumption and large quantities of emissions. Thus, the purpose of our approach is to determine by simulation the working conditions, including the manufacturing mix recipe with the addition of different materials, to minimize the emissions represented by CO and CH4. Our approach determines regression models which perform significantly better than those found using the traditional ICA for the aforementioned problem, resulting in better convergence and a substantially lower error. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optimization" title="optimization">optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=biologically%20inspired%20algorithm" title=" biologically inspired algorithm"> biologically inspired algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=regression%20models" title=" regression models"> regression models</a>, <a href="https://publications.waset.org/abstracts/search?q=bricks" title=" bricks"> bricks</a>, <a href="https://publications.waset.org/abstracts/search?q=emissions" title=" emissions"> emissions</a> </p> <a href="https://publications.waset.org/abstracts/162133/a-hybrid-evolutionary-optimizer-for-modeling-the-process-of-obtaining-bricks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162133.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">82</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">65</span> Neuroevolution Based on Adaptive Ensembles of Biologically Inspired Optimization Algorithms Applied for Modeling a Chemical Engineering Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sabina-Adriana%20Floria">Sabina-Adriana Floria</a>, <a href="https://publications.waset.org/abstracts/search?q=Marius%20Gavrilescu"> Marius Gavrilescu</a>, <a href="https://publications.waset.org/abstracts/search?q=Florin%20Leon"> Florin Leon</a>, <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Curteanu"> Silvia Curteanu</a>, <a href="https://publications.waset.org/abstracts/search?q=Costel%20Anton"> Costel Anton</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Neuroevolution is a subfield of artificial intelligence used to solve various problems in different application areas. Specifically, neuroevolution is a technique that applies biologically inspired methods to generate neural network architectures and optimize their parameters automatically. In this paper, we use different biologically inspired optimization algorithms in an ensemble strategy with the aim of training multilayer perceptron neural networks, resulting in regression models used to simulate the industrial chemical process of obtaining bricks from silicone-based materials. Installations in the raw ceramics industry, i.e., bricks, are characterized by significant energy consumption and large quantities of emissions. In addition, the initial conditions that were taken into account during the design and commissioning of the installation can change over time, which leads to the need to add new mixes to adjust the operating conditions for the desired purpose, e.g., material properties and energy saving. The present approach follows the study by simulation of a process of obtaining bricks from silicone-based materials, i.e., the modeling and optimization of the process. Optimization aims to determine the working conditions that minimize the emissions represented by nitrogen monoxide. We first use a search procedure to find the best values for the parameters of various biologically inspired optimization algorithms. Then, we propose an adaptive ensemble strategy that uses only a subset of the best algorithms identified in the search stage. The adaptive ensemble strategy combines the results of selected algorithms and automatically assigns more processing capacity to the more efficient algorithms. Their efficiency may also vary at different stages of the optimization process. In a given ensemble iteration, the most efficient algorithms aim to maintain good convergence, while the less efficient algorithms can improve population diversity. The proposed adaptive ensemble strategy outperforms the individual optimizers and the non-adaptive ensemble strategy in convergence speed, and the obtained results provide lower error values. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optimization" title="optimization">optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=biologically%20inspired%20algorithm" title=" biologically inspired algorithm"> biologically inspired algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=neuroevolution" title=" neuroevolution"> neuroevolution</a>, <a href="https://publications.waset.org/abstracts/search?q=ensembles" title=" ensembles"> ensembles</a>, <a href="https://publications.waset.org/abstracts/search?q=bricks" title=" bricks"> bricks</a>, <a href="https://publications.waset.org/abstracts/search?q=emission%20minimization" title=" emission minimization"> emission minimization</a> </p> <a href="https://publications.waset.org/abstracts/162135/neuroevolution-based-on-adaptive-ensembles-of-biologically-inspired-optimization-algorithms-applied-for-modeling-a-chemical-engineering-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162135.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">116</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">64</span> Molecular-Genetics Studies of New Unknown APMV Isolated from Wild Bird in Ukraine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Borys%20Stegniy">Borys Stegniy</a>, <a href="https://publications.waset.org/abstracts/search?q=Anton%20Gerilovych"> Anton Gerilovych</a>, <a href="https://publications.waset.org/abstracts/search?q=Oleksii%20Solodiankin"> Oleksii Solodiankin</a>, <a href="https://publications.waset.org/abstracts/search?q=Vitaliy%20Bolotin"> Vitaliy Bolotin</a>, <a href="https://publications.waset.org/abstracts/search?q=Anton%20Stegniy"> Anton Stegniy</a>, <a href="https://publications.waset.org/abstracts/search?q=Denys%20Muzyka"> Denys Muzyka</a>, <a href="https://publications.waset.org/abstracts/search?q=Claudio%20Afonso"> Claudio Afonso</a> </p> <p class="card-text"><strong>Abstract:</strong></p> New APMV was isolated from white fronted goose in Ukraine.

This Mass of the Dead, which was dedicated to the memory of his esteemed friend and mentor Franz Sailer, establishes the beginning of a new creative aesthetic in the composer´s production and links its liturgical development, which is contextualized in the monastery of St. Florian, to the use of a range of musicals possibilities that are projected by Bruckner on an orchestral texture with choir and organ. Set on a strict tridentine ritual model, this requiem exemplifies the religious aesthetics of a composer that is committed to the Catholic faith and that also links to its structure the reinterpretation of a religious model that, despite being romantic, shows a strong influence derived from the baroque or the Viennese Classicism language. Consequently, the study responds to the need to show the survival of the Requiem Mass within the romantic context of Vienna. Therefore, it draws on a detailed analysis of the score and the creative context of the composer with the intention of linking the work to the tradition of the genre and also specifying the stylistic particularities of its musical model within a variability of possibilities such as the contrasting precedents of Mozart, Haydn, Cherubini or Berlioz´s requiems. Tradition or modernity, liturgy or concert hall are aesthetic references that will condition the development of the Requiem Mass in the middle of the nineteenth century. In this context, this paper tries to recover Bruckner's Requiem in Dm as a musical model of the romantic ritual of deceased and as a stylistic reference of a creative composition that will condition the development of later liturgical works such as Liszt or DeLange (1868) ones. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=liturgy" title="liturgy">liturgy</a>, <a href="https://publications.waset.org/abstracts/search?q=religious%20symbolism" title=" religious symbolism"> religious symbolism</a>, <a href="https://publications.waset.org/abstracts/search?q=requiem" title=" requiem"> requiem</a>, <a href="https://publications.waset.org/abstracts/search?q=romanticism" title=" romanticism"> romanticism</a> </p> <a href="https://publications.waset.org/abstracts/63264/anton-bruckners-requiem-in-dm-the-reinterpretation-of-a-liturgical-genre-in-the-viennese-romantic-context" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63264.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">337</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">62</span> Study on the Electrochemical Performance of Graphene Effect on Cadmium Oxide in Lithium Battery </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Atef%20Y.%20Shenouda">Atef Y.

So it can be described as red titanogypsum.

There has been a lot of literature relating deployable structures but with main focus on space applications. The complexities in the design of deployable structures may be the reason only few have been constructed for earth based solutions. This paper intends to explore the possibilities of integrating sustainable design concepts in deployable structures. Key aspects of sustainable design of structures as applicable to deployable structures have not been explored. Sustainable design of structures have mainly been concerned with static structures in the built environment. However, very little literature, concepts or framework has been drafted as it relates to deployable structures or their integration to static structures as a model for sustainable design. This article seeks to address this flaw in sustainable design for structural engineering and to provide a framework for designing structures in a sustainable manner. This framework will apply to deployable structures for earth-based environments as a form of disaster relief measures and also as part of static structures in the built environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deployable%20structures" title="deployable structures">deployable structures</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20design" title=" sustainable design"> sustainable design</a>, <a href="https://publications.waset.org/abstracts/search?q=framework" title=" framework"> framework</a>, <a href="https://publications.waset.org/abstracts/search?q=earth-based%20environments" title=" earth-based environments "> earth-based environments </a> </p> <a href="https://publications.waset.org/abstracts/15693/sustainable-design-in-the-use-of-deployable-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15693.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">541</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> Modeling of Enthalpy and Heat Capacity of Phase-Change Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Igor%20Medved">Igor Medved</a>, <a href="https://publications.waset.org/abstracts/search?q=Anton%20Trnik"> Anton Trnik</a>, <a href="https://publications.waset.org/abstracts/search?q=Libor%20Vozar"> Libor Vozar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Phase-change materials (PCMs) are of great interest in the applications where a temperature level needs to be maintained and/or where there is demand for thermal energy storage. 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">53</span> Radiochemical Purity of 68Ga-BCA-Peptides: Separation of All 68Ga Species with a Single iTLC Strip</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anton%20A.%20Larenkov">Anton A.

In this method iTLC-SG strips and commonly used eluent TFA<sub>aq.</sub> (3-5 % (v/v)) are used. The method allows determining each of the key radiochemical forms of <sup>68</sup>Ga (colloidal, bound, ionic) separately with the peaks separation being no less than 4 σ. <em>Rf</em> = 0.0-0.1 for <sup>68</sup>Ga-colloid; <em>Rf</em> = 0.5-0.6 for <sup>68</sup>Ga-BCA-peptides; <em>Rf</em> = 0.9-1.0 for ionic <sup>68</sup>Ga. The method is simple and fast: For developing length of 75 mm only 4-6 min is required (versus 18-20 min for pharmacopoeial method). The method has been tested on various compounds (including <sup>68</sup>Ga-DOTA-TOC, <sup>68</sup>Ga-DOTA-TATE, <sup>68</sup>Ga-NODAGA-RGD<sub>2</sub> etc.). The cross-validation work for every specific form of <sup>68</sup>Ga showed good correlation between method developed and control (pharmacopoeial) methods.

A series of CFRP-strengthened RC beams was tested to investigate the influence of preload and crack repairing factors on CFRP debonding. IRT was applied to detect the early stage of IC debonding during the laboratory bending tests. It was found that for the beams strengthened under load after crack injecting, СFRP debonding strain is 4-65% lower than for the preliminary strengthened beams. The beams strengthened under the load had a relative area of debonding of 2 times higher than preliminary strengthened beams. The СFRP debonding strain is weakly dependent on the strength of the concrete substrate.

The concentrated solar energy is delivered to the solar cell from 20 to 100 W/cm². Some of this energy is converted to electricity, while the rest must be disposed of as a residual heat. Solar cells cooling should be a necessary part of CPV modeling because these systems allowed increasing the power received by the cell. This high power can rise the electrons’ potential causing the heating of the cell, which reduces the global module’s efficiency. This work consists of modeling a concentrating photovoltaic module with and without a cooling system. We have established a theoretical model based on energy balances carried out on a photovoltaic module using solar radiation concentration cells. Subsequently, we developed a calculation program on Matlab which allowed us to simulate the functioning of this module. The obtained results show that the addition of a cooling system to the module improves greatly the performance of our CPV system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20energy" title="solar energy">solar energy</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaic" title=" photovoltaic"> photovoltaic</a>, <a href="https://publications.waset.org/abstracts/search?q=concentration" title=" concentration"> concentration</a>, <a href="https://publications.waset.org/abstracts/search?q=cooling" title=" cooling"> cooling</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20improvement" title=" performance improvement"> performance improvement</a> </p> <a href="https://publications.waset.org/abstracts/62511/modeling-of-a-concentrating-photovoltaic-module-with-and-without-cooling-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62511.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">398</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">50</span> Teaching Entrepreneurship in Light of the Triple Bottom Line</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sherry%20Robinson">Sherry Robinson</a>, <a href="https://publications.waset.org/abstracts/search?q=Hans%20Anton%20Stubberud"> Hans Anton Stubberud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Entrepreneurship can take many forms. Traditional entrepreneurs seek profits and growth for the businesses they start themselves. Intrapreneurs act entrepreneurially within a business they do not own. Social entrepreneurs have goals other than (but not excluding) profit and growth as they seek to solve social problems or protect the environment. This type of entrepreneur often focuses on the triple bottom line, which includes a concern for people and the planet as well as profit. Ecopreneurs in particular are driven by their desire to create and promote environmentally sustainable products and processes. All of these entrepreneurs need an entrepreneurial orientation in order to survive and thrive. The three most common elements of an entrepreneurial orientation are (1) creativity and innovation, (2) the willingness to take risks and (3) the proactiveness to put ideas into action. This study describes an interdisciplinary entrepreneurship course integrating topics regarding the triple bottom line with those relevant to an entrepreneurial orientation. The results show that students significantly increased their skill levels in many areas, including soft skills such as communicating and working in teams, as well as designing innovative products and taking calculated risk. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=creativity" title="creativity">creativity</a>, <a href="https://publications.waset.org/abstracts/search?q=entrepreneurship%20education" title=" entrepreneurship education"> entrepreneurship education</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=triple%20bottom%20line" title=" triple bottom line"> triple bottom line</a> </p> <a href="https://publications.waset.org/abstracts/25618/teaching-entrepreneurship-in-light-of-the-triple-bottom-line" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25618.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">475</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> Density Measurement of Mixed Refrigerants R32+R1234yf and R125+R290 from 0°C to 100°C and at Pressures up to 10 MPa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xiaoci%20Li">Xiaoci Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Yonghua%20Huang"> Yonghua Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hui%20Lin"> Hui Lin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Optimization of the concentration of components in mixed refrigerants leads to potential improvement of either thermodynamic cycle performance or safety performance of heat pumps and refrigerators.

The p-ρ-T data of these mixtures are one of the fundamental and necessary properties for design and evaluation of the performance of the heat pumps. Although the property data of mixtures can be predicted by the mixing models based on the pure substances incorporated in programs such as the NIST database Refprop, direct property measurement will still be helpful to reveal the true state behaviors and verify the models. Densities of the mixtures of R32+R1234yf an d R125+R290 are measured by an Anton Paar U shape oscillating tube digital densimeter DMA-4500 in the range of temperatures from 0°C to 100 °C and pressures up to 10 MPa.

The basic materials to make this starter-generator (SG) were selected and justified. Multi-criteria optimization of the developed structural scheme was performed using a genetic algorithm and Pareto method. The optimum (in Pareto terms) active length and thickness of permanent magnets of SG were selected as a result of the optimization. Using the dimensions obtained, allowed to reduce the weight of the designed SG by 10 kg relative to a base option at constant thermal loads. Multidisciplinary computer simulation was performed on the basis of the optimum geometric dimensions, which proved performance efficiency of the design. We further plan to make a full-scale sample of SG of HPS and publish the results of its experimental research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high-temperature%20starter-generator" title="high-temperature starter-generator">high-temperature starter-generator</a>, <a href="https://publications.waset.org/abstracts/search?q=more%20electrical%20engine" title=" more electrical engine"> more electrical engine</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-criteria%20optimization" title=" multi-criteria optimization"> multi-criteria optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=permanent%20magnet" title=" permanent magnet"> permanent magnet</a> </p> <a href="https://publications.waset.org/abstracts/55524/multi-criteria-optimization-of-high-temperature-reversed-starter-generator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55524.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">367</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> Influence of Silica Fume on the Hydration of Cement Pastes Studied by Simultaneous TG-DSC Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anton%20Trn%C3%ADk">Anton Trník</a>, <a href="https://publications.waset.org/abstracts/search?q=Lenka%20Scheinherrov%C3%A1"> Lenka Scheinherrová</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20%C4%8Cern%C3%BD"> Robert Černý</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Silica fume is a by-product of the ferro-silicon and silicon metal industries. It is mainly in the form of amorphous silica. Silica fume belongs to pozzolanic active materials which can be used in concrete to improve its final properties. In this paper, the influence of silica fume on hydration of cement pastes is studied using differential scanning calorimetry (DSC) and thermogravimetry (TG) at various curing times (2, 7, 28, and 90 days) in the temperature range from 25 to 1000 °C in an argon atmosphere. Samples are prepared from Portland cement CEM I 42.5 R which is partially replaced with the silica fume of 4, 8, and 12 wt.%. The water/binder ratio is chosen as 0.5. It is identified and described the liberation of physically bound water, calcium–silicate–hydrates dehydration, portlandite and calcite decomposition in studied samples. Also, it is found out that an exothermic peak at 950 °C is observed without a significant mass change for samples with 12 wt.% of silica fume after two days of hydration. This peak is probably caused by the pozzolanic reaction between silica fume and Portland cement. Its size corresponds to the degree of crystallization between Ca and Si. The portlandite content is lower for the samples with a higher amount of silica fume. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=differential%20scanning%20calorimetry" title="differential scanning calorimetry">differential scanning calorimetry</a>, <a href="https://publications.waset.org/abstracts/search?q=hydration" title=" hydration"> hydration</a>, <a href="https://publications.waset.org/abstracts/search?q=silica%20fume" title=" silica fume"> silica fume</a>, <a href="https://publications.waset.org/abstracts/search?q=thermogravimetry" title=" thermogravimetry"> thermogravimetry</a> </p> <a href="https://publications.waset.org/abstracts/62051/influence-of-silica-fume-on-the-hydration-of-cement-pastes-studied-by-simultaneous-tg-dsc-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62051.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">240</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">46</span> Component Interface Formalization in Robotic Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anton%20Hristozov">Anton Hristozov</a>, <a href="https://publications.waset.org/abstracts/search?q=Eric%20Matson"> Eric Matson</a>, <a href="https://publications.waset.org/abstracts/search?q=Eric%20Dietz"> Eric Dietz</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcus%20Rogers"> Marcus Rogers</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Components are heavily used in many software systems, including robotics systems. The growth of sophistication and diversity of new capabilities for robotic systems presents new challenges to their architectures. Their complexity is growing exponentially with the advent of AI, smart sensors, and the complex tasks they have to accomplish. Such complexity requires a more rigorous approach to the creation, use, and interoperability of software components. The issue is exacerbated because robotic systems are becoming more and more reliant on third-party components for certain functions. In order to achieve this kind of interoperability, including dynamic component replacement, we need a way to standardize their interfaces. A formal approach is desperately needed to specify what an interface of a robotic software component should contain. This study performs an analysis of the issue and presents a universal and generic approach to standardizing component interfaces for robotic systems. Our approach is inspired by well-established robotic architectures such as ROS, PX4, and Ardupilot. The study is also applicable to other software systems that share similar characteristics with robotic systems. We consider the use of JSON or Domain Specific Languages (DSL) development with tools such as Antlr and automatic code and configuration file generation for frameworks such as ROS and PX4. A case study with ROS2 is presented as a proof of concept for the proposed methodology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CPS" title="CPS">CPS</a>, <a href="https://publications.waset.org/abstracts/search?q=robots" title=" robots"> robots</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20architecture" title=" software architecture"> software architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=interface" title=" interface"> interface</a>, <a href="https://publications.waset.org/abstracts/search?q=ROS" title=" ROS"> ROS</a>, <a href="https://publications.waset.org/abstracts/search?q=autopilot" title=" autopilot"> autopilot</a> </p> <a href="https://publications.waset.org/abstracts/148295/component-interface-formalization-in-robotic-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148295.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">92</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">45</span> The Effectiveness of Herbal Capsules Ethanol Extract of Celery (Apium graveolens L.) and Bulb of Garlic (Allium sativum L.) in Lowering Total Cholesterol Levels in Patients with Hypercholesterolemia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anton%20Bahtiar">Anton Bahtiar</a>, <a href="https://publications.waset.org/abstracts/search?q=Lukas%20Tjandra%20Leksana"> Lukas Tjandra Leksana</a>, <a href="https://publications.waset.org/abstracts/search?q=Fransiscus%20D.%20Suyatna"> Fransiscus D.

Under illumination with visible light, the photosensitizers are excited and transfer the absorbed energy to the oxygen dissolved in an aqueous phase, leading to production of a reactive oxygen species which cause irreversible damage to bacterial cells. When immobilized onto a solid phase, photosensitizers preserve their antibacterial properties. In the present study, photosensitizers were immobilized in polyethylene or propylene and tested for antimicrobial activity against Gram-positive S. aureus, S. epidermidis and Streptococcus sp. For this purpose, water-soluble photosensitizers, Rose Bengal sodium salt, and methylene blue as well as water-insoluble hematoporphyrin and Rose Bengal lactone, were immobilized by dissolution in melted polymers to yield 3 mm diameter rods and 3-5 mm beads. All four photosensitizers were found to be effective in the eradication of Gram-positive bacteria under illumination by a white luminescent lamp or sunlight. The immobilized photosensitizers can be applied for continuous water disinfection; they can be easily removed at the end of the treatment and reused. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20polymers" title="antimicrobial polymers">antimicrobial polymers</a>, <a href="https://publications.waset.org/abstracts/search?q=gram-positive%20bacteria" title=" gram-positive bacteria"> gram-positive bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=immobilization%20of%20photosensitizers" title=" immobilization of photosensitizers"> immobilization of photosensitizers</a>, <a href="https://publications.waset.org/abstracts/search?q=photodynamic%20antibacterial%20activity" title=" photodynamic antibacterial activity"> photodynamic antibacterial activity</a> </p> <a href="https://publications.waset.org/abstracts/46641/eradication-of-gram-positive-bacteria-by-photosensitizers-immobilized-in-polymers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46641.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">241</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">43</span> Catalytic Combustion of Methane over Pd-Meox-CeO₂/Al₂O₃ (Me= Co or Ni) Catalysts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Silviya%20Todorova">Silviya Todorova</a>, <a href="https://publications.waset.org/abstracts/search?q=Anton%20Naydenov"> Anton Naydenov</a>, <a href="https://publications.waset.org/abstracts/search?q=Ralitsa%20Velinova"> Ralitsa Velinova</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexander%20Larin"> Alexander Larin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Catalytic combustion of methane has been extensively investigated for emission control and power generation during the last decades. The alumina-supported palladium catalyst is widely accepted as the most active catalysts for catalytic combustion of methane. The activity of Pd/Al₂O₃ decreases during the time on stream, especially underwater vapor. The following order of activity in the reaction of complete oxidation of methane was established: Co₃O₄> CuO>NiO> Mn₂O₃> Cr₂O₃. It may be expected that the combination between Pd and these oxides could lead to the promising catalysts in the reaction of complete methane. In the present work, we investigate the activity of Pd/Al₂O₃ catalysts promoted with other metal oxides (MOx; M= Ni, Co, Ce). The Pd-based catalysts modified by metal oxide were prepared by sequential impregnation of Al₂O₃ with aqueous solutions of Me(NO₃)₂.6H₂O and Pd(NO₃)₂H₂O. All samples were characterized by X-ray diffraction (XRD), temperature-programmed reduction (TPR), and X-ray photoelectron spectroscopy (XPS). An improvement of activity was observed after modification with different oxides. The results demonstrate that the Pd/Al₂O₃ catalysts modified with Co and Ce by impregnation with a common solution of respective salts, exhibit the most promising catalytic activity for methane oxidation. Most probably, the presence of Co₃O₄ and CeO₂ on catalytic surface increases surface oxygen and therefore leads to the better reactivity in methane combustion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=methane%20combustion" title="methane combustion">methane combustion</a>, <a href="https://publications.waset.org/abstracts/search?q=palladium" title=" palladium"> palladium</a>, <a href="https://publications.waset.org/abstracts/search?q=Co-Ce" title=" Co-Ce"> Co-Ce</a>, <a href="https://publications.waset.org/abstracts/search?q=Ni-Ce" title=" Ni-Ce"> Ni-Ce</a> </p> <a href="https://publications.waset.org/abstracts/110568/catalytic-combustion-of-methane-over-pd-meox-ceo2al2o3-me-co-or-ni-catalysts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110568.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">186</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> Risk Mitigation of Data Causality Analysis Requirements AI Act</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rapha%C3%ABl%20Weuts">Raphaël Weuts</a>, <a href="https://publications.waset.org/abstracts/search?q=Mykyta%20Petik"> Mykyta Petik</a>, <a href="https://publications.waset.org/abstracts/search?q=Anton%20Vedder"> Anton Vedder</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Artificial Intelligence has the potential to create and already creates enormous value in healthcare. Prescriptive systems might be able to make the use of healthcare capacity more efficient. Such systems might entail interpretations that exclude the effect of confounders that brings risks with it. Those risks might be mitigated by regulation that prevents systems entailing such risks to come to market. One modality of regulation is that of legislation, and the European AI Act is an example of such a regulatory instrument that might mitigate these risks. To assess the risk mitigation potential of the AI Act for those risks, this research focusses on a case study of a hypothetical application of medical device software that entails the aforementioned risks. The AI Act refers to the harmonised norms for already existing legislation, here being the European medical device regulation. The issue at hand is a causal link between a confounder and the value the algorithm optimises for by proxy. The research identifies where the AI Act already looks at confounders (i.a. feedback loops in systems that continue to learn after being placed on the market). The research identifies where the current proposal by parliament leaves legal uncertainty on the necessity to check for confounders that do not influence the input of the system, when the system does not continue to learn after being placed on the market. The authors propose an amendment to article 15 of the AI Act that would require high-risk systems to be developed in such a way as to mitigate risks from those aforementioned confounders. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AI%20Act" title="AI Act">AI Act</a>, <a href="https://publications.waset.org/abstracts/search?q=healthcare" title=" healthcare"> healthcare</a>, <a href="https://publications.waset.org/abstracts/search?q=confounders" title=" confounders"> confounders</a>, <a href="https://publications.waset.org/abstracts/search?q=risks" title=" risks"> risks</a> </p> <a href="https://publications.waset.org/abstracts/170546/risk-mitigation-of-data-causality-analysis-requirements-ai-act" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170546.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">259</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">41</span> Botulinum A Toxin Injection in Two Filipino Brothers with X-linked Dystonia-Parkinsonism (XDP) in Cebu City, Philippines: A Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ana%20Katrina%20C.%20Longos">Ana Katrina C.

Discussion: A 54 year old man presented initially with parkinsonian symptoms and later developed oromandibular and truncal dystonia. Further history revealed that he had an older brother who also presented with the same symptoms. Neuroimaging done on both patients revealed CVD infarcts in the pons and corona radiata respectively which where were not compatible with their symptoms. Family history revealed that their mother was originally from Panay and a diagnosis of X-linked dystonia parkinsonism (XDP) was made. Both patients were able to receive botulinum A toxin injections which provided temporary relief of symptoms. Conclusion: XDP was considered in 2 Filipino male siblings who presented with oromandibular dystonia, truncal dystonia, shuffling gait, resting tremors with ancestry from Panay on the maternal side. There is no cure for XDP, only symptomatic treatment. Until recently, only oral chemotherapy was available in Cebu. Botulinum A toxin injection done in both patients afforded temporary resolution of symptoms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=XDP" title="XDP">XDP</a>, <a href="https://publications.waset.org/abstracts/search?q=dystonia%20of%20Panay" title=" dystonia of Panay"> dystonia of Panay</a>, <a href="https://publications.waset.org/abstracts/search?q=lubag" title=" lubag"> lubag</a>, <a href="https://publications.waset.org/abstracts/search?q=dystonia%20parkinsonism" title=" dystonia parkinsonism"> dystonia parkinsonism</a>, <a href="https://publications.waset.org/abstracts/search?q=botulinum%20a%20toxin" title=" botulinum a toxin"> botulinum a toxin</a> </p> <a href="https://publications.waset.org/abstracts/17168/botulinum-a-toxin-injection-in-two-filipino-brothers-with-x-linked-dystonia-parkinsonism-xdp-in-cebu-city-philippines-a-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17168.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">504</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> Characterization of Filled HNBR Elastomers for Sealing Application in Cold Climate Areas</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anton%20G.%20Akulichev">Anton G.

There is a technology gap between the properties of existing elastomeric sealing materials and the properties needed for service in extremely cold regions. Moreover, some aspects of low temperature behaviour of rubber are not thoroughly studied and understood. The paper presents results of laboratory testing of a conventional oilfield HNBR (hydrogenated nitrile butadiene rubber) elastomer at low climatic temperatures above and below its glass transition point, as well as the performance of some filled HNBR formulations. Particular emphasis in the experiments is put on rubber viscoelastic characteristics studied by Dynamic Mechanical Analysis (DMA) and quasi-static mechanical testing results at low temperatures. As demonstrated by the stress relaxation and DMA experiments the transition region near Tg of the studied compound has the most striking features, like rapid stress relaxation, as compared to the glassy and rubbery plateau. In addition the quasi-static experiments show that molecular movement below Tg is not completely frozen, but rather evident and manifested in a certain stress decay as well. The effect of temperature and filler additions on typical mechanical and other properties of the materials is also discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=characterization" title="characterization">characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=filled%20elastomers" title=" filled elastomers"> filled elastomers</a>, <a href="https://publications.waset.org/abstracts/search?q=HNBR" title=" HNBR"> HNBR</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20temperature" title=" low temperature"> low temperature</a> </p> <a href="https://publications.waset.org/abstracts/39211/characterization-of-filled-hnbr-elastomers-for-sealing-application-in-cold-climate-areas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39211.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">313</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">39</span> Virtual Modelling of Turbulent Fibre Flow in a Low Consistency Refiner for a Sustainable and Energy Efficient Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Simon%20Ingelsten">Simon Ingelsten</a>, <a href="https://publications.waset.org/abstracts/search?q=Anton%20Lundberg"> Anton Lundberg</a>, <a href="https://publications.waset.org/abstracts/search?q=Vijay%20Shankar"> Vijay Shankar</a>, <a href="https://publications.waset.org/abstracts/search?q=Lars-Olof%20Landstr%C3%B6m"> Lars-Olof Landström</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%96rjan%20Johansson"> Örjan Johansson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The flow in a low consistency disc refiner is simulated with the aim of identifying flow structures possibly being of importance for a future study to optimise the energy efficiency in refining processes. A simplified flow geometry is used, where a single groove of a refiner disc is modelled. Two different fibre models are used to simulate turbulent fibre suspension flow in the groove. The first model is a Bingham viscoplastic fluid model where the fibre suspension is treated as a non-Newtonian fluid with a yield stress. The second model is a new model proposed in a recent study where the suspended fibres effect on flow is accounted for through a modelled orientation distribution function (ODF). Both models yielded similar results with small differences. Certain flow characteristics that were expected and that was found in the literature were identified. Some of these flow characteristics may be of importance in a future process to optimise the refiner geometry to increase the energy efficiency. Further study and a more detailed flow model is; however, needed in order for the simulations to yield results valid for quantitative use in such an optimisation study. An outline of the next steps in such a study is proposed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=disc%20refiner" title="disc refiner">disc refiner</a>, <a href="https://publications.waset.org/abstracts/search?q=fibre%20flow" title=" fibre flow"> fibre flow</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=turbulence%20modelling" title=" turbulence modelling"> turbulence modelling</a> </p> <a href="https://publications.waset.org/abstracts/33652/virtual-modelling-of-turbulent-fibre-flow-in-a-low-consistency-refiner-for-a-sustainable-and-energy-efficient-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33652.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">406</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> Plasma Treatment of a Lignite Using Water-Stabilized Plasma Torch at Atmospheric Pressure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anton%20Serov">Anton Serov</a>, <a href="https://publications.waset.org/abstracts/search?q=Alan%20Maslani"> Alan Maslani</a>, <a href="https://publications.waset.org/abstracts/search?q=Michal%20Hlina"> Michal Hlina</a>, <a href="https://publications.waset.org/abstracts/search?q=Vladimir%20Kopecky"> Vladimir Kopecky</a>, <a href="https://publications.waset.org/abstracts/search?q=Milan%20Hrabovsky"> Milan Hrabovsky</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recycling of organic waste is an increasingly hot topic in recent years. This issue becomes even more interesting if the raw material for the fuel production can be obtained as the result of that recycling. A process of high-temperature decomposition of a lignite (a non-hydrolysable complex organic compound) was studied on the plasma gasification reactor PLASGAS, where water-stabilized plasma torch was used as a source of high enthalpy plasma. The plasma torch power was 120 kW and allowed heating of the reactor to more than 1000 °C. The material feeding rate in the gasification reactor was selected 30 and 60 kg per hour that could be compared with small industrial production. An efficiency estimation of the thermal decomposition process was done. A balance of the torch energy distribution was studied as well as an influence of the lignite particle size and an addition of methane (CH4) in a reaction volume on the syngas composition (H2+CO). It was found that the ratio H2:CO had values in the range of 1,5 to 2,5 depending on the experimental conditions. The recycling process occurred at atmospheric pressure that was one of the important benefits because of the lack of expensive vacuum pump systems. The work was supported by the Grant Agency of the Czech Republic under the project GA15-19444S. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atmospheric%20pressure" title="atmospheric pressure">atmospheric pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=lignite" title=" lignite"> lignite</a>, <a href="https://publications.waset.org/abstracts/search?q=plasma%20treatment" title=" plasma treatment"> plasma treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=water-stabilized%20plasma%20torch" title=" water-stabilized plasma torch"> water-stabilized plasma torch</a> </p> <a href="https://publications.waset.org/abstracts/47529/plasma-treatment-of-a-lignite-using-water-stabilized-plasma-torch-at-atmospheric-pressure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47529.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">373</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">37</span> Increasing the Forecasting Fidelity of Current Collection System Operating Capability by Means of Contact Pressure Simulation Modelling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anton%20Golubkov">Anton Golubkov</a>, <a href="https://publications.waset.org/abstracts/search?q=Gleb%20Ermachkov"> Gleb Ermachkov</a>, <a href="https://publications.waset.org/abstracts/search?q=Aleksandr%20Smerdin"> Aleksandr Smerdin</a>, <a href="https://publications.waset.org/abstracts/search?q=Oleg%20Sidorov"> Oleg Sidorov</a>, <a href="https://publications.waset.org/abstracts/search?q=Victor%20Philippov"> Victor Philippov</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Current collection quality is one of the limiting factors when increasing trains movement speed in the rail sector. With the movement speed growth, the impact forces on the current collector from the rolling stock and the aerodynamic influence increase, which leads to the spread in the contact pressure values, separation of the current collector head from the contact wire, contact arcing and excessive wear of the contact elements. The upcoming trend in resolving this issue is the use of the automatic control systems providing stabilization of the contact pressure value. The present paper considers the features of the contemporary automatic control systems of the current collector’s pressure; their major disadvantages have been stated. A scheme of current collector pressure automatic control has been proposed, distinguished by a proactive influence on undesirable effects. A mathematical model of contact strips wearing has been presented, obtained in accordance with the provisions of the central composition rotatable design program. The analysis of the obtained dependencies has been carried out. The procedures for determining the optimal current collector pressure on the contact wire and the pressure control principle in the pneumatic drive have been described. <p
