In the communicative approach, real communication is both the objective of learning and the means through which it takes place. This approach was initiated during the 1970’s and quickly became prominent, as it proposed an alternative to the previous systems-oriented approaches. In other words, instead of focusing on the acquisition of grammar and vocabulary, the communicative approach aims at developing students’ competence to communicate in the target language with an enhanced focus on real-life situations. To put it in an nutshell, CLT considers using the language to be just as important as actually learning the language. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=communication" title="communication">communication</a>, <a href="https://publications.waset.org/abstracts/search?q=approach" title=" approach"> approach</a>, <a href="https://publications.waset.org/abstracts/search?q=objective" title=" objective"> objective</a>, <a href="https://publications.waset.org/abstracts/search?q=learning" title=" learning"> learning</a> </p> <a href="https://publications.waset.org/abstracts/135764/enhancing-communicative-skills-for-students-in-automatics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135764.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">160</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">102</span> Production Structures of Energy Based on Water Force, Its Infrastructure Protection, and Possible Causes of Failure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gabriela-Andreea%20Despescu">Gabriela-Andreea Despescu</a>, <a href="https://publications.waset.org/abstracts/search?q=M%C4%83d%C4%83lina-Elena%20Mavrodin"> Mădălina-Elena Mavrodin</a>, <a href="https://publications.waset.org/abstracts/search?q=Gheorghe%20L%C4%83z%C4%83roiu"> Gheorghe Lăzăroiu</a>, <a href="https://publications.waset.org/abstracts/search?q=Florin%20Adrian%20Gr%C4%83dinaru"> Florin Adrian Grădinaru</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this paper is to contribute to the enhancement of a hydroelectric plant protection by coordinating protection measures and existing security and introducing new measures under a risk management process.

Recent scholarship about ‘prophetic’ voices in fiction considers The Last Man an influential but overlooked novel deserving of renewed scholarly interest. Through close textual analysis and comparative reading, this paper seeks to explore the continuities (and discontinuities) in thematic concern of creator and creation in Frankenstein and The Last Man, emblematic in the oppositional characters of Victor Frankenstein and the Creature and Adrian, Earl of Windsor and Lionel Verney, his ‘creation’ in The Last Man. It argues that the creator/creation dynamic between Frankenstein and the Creature is to an extent revisited and inverted in Adrian and Verney but presented as no less problematic in The Last Man’s critique of man’s inevitable folly despite nurturing and acceptance of the marginalised figure. Drawing on Romanticism ideals of nature, its foregrounding of a scourging pandemic as punishment for man’s self-dislocation and with nature is a mirroring of Frankenstein and the Creature’s own plague-like deterioration and alienation from self and nature. In a sense, both Verney and the Creature as solitary figures at the novels' denouement are ‘last men’, having learned much about man and society and upon whom the moral injunction rests. In Verney, however, the moral warning coupled with the hope that man can yet be saved offers a different reading perhaps from Frankenstein regarding the creator/creation dichotomy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=creator%2Fcreation" title="creator/creation">creator/creation</a>, <a href="https://publications.waset.org/abstracts/search?q=Frankenstein" title=" Frankenstein"> Frankenstein</a>, <a href="https://publications.waset.org/abstracts/search?q=Mary%20Shelley" title=" Mary Shelley"> Mary Shelley</a>, <a href="https://publications.waset.org/abstracts/search?q=The%20Gothic" title=" The Gothic"> The Gothic</a>, <a href="https://publications.waset.org/abstracts/search?q=The%20Last%20Man" title=" The Last Man"> The Last Man</a> </p> <a href="https://publications.waset.org/abstracts/135045/creator-and-creation-mary-shelleys-monstrous-last-men-in-frankenstein-and-the-last-man" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135045.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">100</span> Temperature Distribution in Friction Stir Welding Using Finite Element Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Armansyah">Armansyah</a>, <a href="https://publications.waset.org/abstracts/search?q=I.%20P.%20Almanar"> I.

In order to obtain temperature distribution in the welded aluminum plates during welding operation, transient thermal finite element analyses are performed. Heat input from tool shoulder and tool pin are considered in the model. A moving heat source with a heat distribution simulating the heat generated by frictions between tool shoulder and workpiece is used in the analysis. Three-dimensional model for simulated process is carried out by using Altair HyperWork, a commercially available software. Transient thermal finite element analyses are performed in order to obtain the temperature distribution in the welded Aluminum plates during welding operation. The developed model was then used to show the effect of various input parameters such as total rate of welding speed and rotational speed on temperature distribution in the workpiece. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=frictions%20stir%20welding" title="frictions stir welding">frictions stir welding</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature%20distribution" title=" temperature distribution"> temperature distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title=" finite element method"> finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=altair%20hyperwork" title=" altair hyperwork"> altair hyperwork</a> </p> <a href="https://publications.waset.org/abstracts/14092/temperature-distribution-in-friction-stir-welding-using-finite-element-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14092.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">543</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">99</span> A Multi-Agent Urban Traffic Simulator for Generating Autonomous Driving Training Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Florin%20Leon">Florin Leon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper describes a simulator of traffic scenarios tailored to facilitate autonomous driving model training for urban environments.

Classic wastewater treatment removes most pollutants but, for some chemical residues, special methods are needed. Carbon nanotubes and other carbon materials might be used in many cases [1-2], especially for heavy metals removal but also on pharmaceutical products such as paracetamol [3]. Our research has confirmed the better efficiency of nanotubes compared to graphene on paracetamol removal from water, but even better results were obtained on single-walled nanotubes (SWCNTs) and graphene nanoplatelets. This can be due to their better dispersion in water which leads to an increased contact surface, so we propose a filtration system of membranes and carbon materials that can be used for paracetamol removal from wastewater but also for other drugs that affect the aquatic life as well as terrestrial animals and people who use this contaminated water. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=applied%20physics" title="applied physics">applied physics</a>, <a href="https://publications.waset.org/abstracts/search?q=wastewater" title=" wastewater"> wastewater</a>, <a href="https://publications.waset.org/abstracts/search?q=nanomaterials" title=" nanomaterials"> nanomaterials</a>, <a href="https://publications.waset.org/abstracts/search?q=enviromental%20science" title=" enviromental science"> enviromental science</a> </p> <a href="https://publications.waset.org/abstracts/142289/drug-residues-disposal-from-wastewater-using-carbon-nanomaterials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142289.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">189</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">97</span> A Bacterial Foraging Optimization Algorithm Applied to the Synthesis of Polyacrylamide Hydrogels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <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> </p> <p class="card-text"><strong>Abstract:</strong></p> The Bacterial Foraging Optimization (BFO) algorithm is inspired by the behavior of bacteria such as <em>Escherichia coli</em> or <em>Myxococcus xanthus</em> when searching for food, more precisely the chemotaxis behavior. Bacteria perceive chemical gradients in the environment, such as nutrients, and also other individual bacteria, and move toward or in the opposite direction to those signals. The application example considered as a case study consists in establishing the dependency between the reaction yield of hydrogels based on polyacrylamide and the working conditions such as time, temperature, monomer, initiator, crosslinking agent and inclusion polymer concentrations, as well as type of the polymer added. This process is modeled with a neural network which is included in an optimization procedure based on BFO. An experimental study of BFO parameters is performed. The results show that the algorithm is quite robust and can obtain good results for diverse combinations of parameter values. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bacterial%20foraging" title="bacterial foraging">bacterial foraging</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogels" title=" hydrogels"> hydrogels</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling%20and%20optimization" title=" modeling and optimization"> modeling and optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20networks" title=" neural networks"> neural networks</a> </p> <a href="https://publications.waset.org/abstracts/106154/a-bacterial-foraging-optimization-algorithm-applied-to-the-synthesis-of-polyacrylamide-hydrogels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106154.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">96</span> Exploring Pisa Monuments Using Mobile Augmented Reality</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mihai%20Duguleana">Mihai Duguleana</a>, <a href="https://publications.waset.org/abstracts/search?q=Florin%20Girbacia"> Florin Girbacia</a>, <a href="https://publications.waset.org/abstracts/search?q=Cristian%20Postelnicu"> Cristian Postelnicu</a>, <a href="https://publications.waset.org/abstracts/search?q=Raffaello%20Brodi"> Raffaello Brodi</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcello%20Carrozzino"> Marcello Carrozzino</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Augmented Reality (AR) has taken a big leap with the introduction of mobile applications which co-locate bi-dimensional (e.g. photo, video, text) and tridimensional information with the location of the user enriching his/her experience.

We propose a location-based AR application which combines co-location with the augmented visual information about Pisa monuments to establish a friendly navigation in this historic city. AR was used to render contextual visual information in the outdoor environment. The developed Android-based application offers two different options: it provides the ability to identify the monuments positioned close to the user’s position and it offers location information for getting near the key touristic objectives.

With its high increased mortality rate, as well as low survival rate combined with high resistance to chemotherapy CC, represents one of the most important global health issues. In the presented research, we have developed a distinct nanostructured colon carcinoma vaccine model based on a nano-biosystem composed of 39 nm gold nanoparticles conjugated to colon cancer epitopes. We prove by means of proteomic analysis, immunocytochemistry, flow cytometry and hyperspectral microscopy that our developed nanobioconjugate was able to contribute to an optimal prophylactic effect against CC by promoting major histocompatibility complex mediated (MHC) antigen presentation by dendritic cells. We may conclude that the proposed immunoprophylactic approach could be more effective than the current treatments of CC because it promotes recognition of the tumoral antigens by the immune system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anticancer%20vaccine" title="anticancer vaccine">anticancer vaccine</a>, <a href="https://publications.waset.org/abstracts/search?q=colon%20cancer" title=" colon cancer"> colon cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=gold%20nanoparticles" title=" gold nanoparticles"> gold nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=tumor%20antigen" title=" tumor antigen"> tumor antigen</a> </p> <a href="https://publications.waset.org/abstracts/33389/specific-colon-cancer-prophylaxis-using-dendritic-stem-cells-and-gold-nanoparticles-functionalized-with-colon-cancer-epitopes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33389.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">453</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">94</span> Health Status Monitoring of COVID-19 Patient's through Blood Tests and Naïve-Bayes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Arias-Alcaide">Carlos Arias-Alcaide</a>, <a href="https://publications.waset.org/abstracts/search?q=Cristina%20Soguero-Ruiz"> Cristina Soguero-Ruiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Paloma%20Santos-%C3%81lvarez"> Paloma Santos-Álvarez</a>, <a href="https://publications.waset.org/abstracts/search?q=Adri%C3%A1n%20Garc%C3%ADa-Romero"> Adrián García-Romero</a>, <a href="https://publications.waset.org/abstracts/search?q=Inmaculada%20Mora-Jim%C3%A9nez"> Inmaculada Mora-Jiménez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Analysing clinical data with computers in such a way that have an impact on the practitioners’ workflow is a challenge nowadays.

Flows deflected by a curved surface have caused great interest during last fifty years a major interest in the study of this phenomenon is caused by the possibility of using this effect to aircraft with short take-off and landing, for thrust vectoring. It is also used in applications involving mixing two of more fluids, noise attenuation, ventilation, etc. The paper proposes the numerical study of an aerodynamic configuration that can passively amplify the Coanda effect. On a wing flaps with predetermined configuration, a channel is applied between two particular zones, a low-pressure one and a high-pressure another one, respectively. The secondary flow through this channel yields a gap between the jet and the convex surface, maintaining the jet attached on a longer distance. The section altering-based active control of the secondary flow through the channel controls the attachment of the jet to the surface and automatically controls the deviation angle of the jet. The numerical simulations have been performed in Ansys Fluent for a series of wing flaps-channel configurations with varying jet velocity. The numerical results are in good agreement with experimental results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blowing%20jet" title="blowing jet">blowing jet</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD" title=" CFD"> CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=Coanda%20effect" title=" Coanda effect"> Coanda effect</a>, <a href="https://publications.waset.org/abstracts/search?q=circulation%20control" title=" circulation control"> circulation control</a> </p> <a href="https://publications.waset.org/abstracts/67867/numerical-investigations-on-the-coanda-effect" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67867.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">346</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">92</span> Numerical Analysis of the Coanda Effect on the Classical Interior Ejectors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alexandru%20Dumitrache">Alexandru Dumitrache</a>, <a href="https://publications.waset.org/abstracts/search?q=Florin%20Frunzulica"> Florin Frunzulica</a>, <a href="https://publications.waset.org/abstracts/search?q=Octavian%20Preotu"> Octavian Preotu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The flow mitigation detachment problem near solid surfaces, resulting in improved globally aerodynamic performance by exploiting the Coanda effect on surfaces, has been addressed extensively in the literature, since 1940. The research is carried on and further developed, using modern means of calculation and new experimental methods. In this paper, it is shown interest in the detailed behavior of a classical interior ejector assisted by the Coanda effect, used in propulsion systems. For numerical investigations, an implicit formulation of RANS equations for axisymmetric flow with a shear stress transport k- ω (SST model) turbulence model is used. The obtained numerical results emphasize the efficiency of the ejector, depending on the physical parameters of the flow and the geometric configuration. Furthermore, numerical investigations are carried out regarding the evolution of the Reynolds number when the jet is attached to the wall, considering three geometric configurations: sudden expansion, open cavity and sudden expansion with divergent at the inlet. Therefore, further insight into complexities involving issues such as the variety of flow structure and the related bifurcation and flow instabilities are provided. Thus, the conditions and the limits within which one can benefit from the advantages of Coanda-type flows are determined. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Coanda%20effect" title="Coanda effect">Coanda effect</a>, <a href="https://publications.waset.org/abstracts/search?q=Coanda%20ejector" title=" Coanda ejector"> Coanda ejector</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD" title=" CFD"> CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=stationary%20bifurcation" title=" stationary bifurcation"> stationary bifurcation</a>, <a href="https://publications.waset.org/abstracts/search?q=sudden%20expansion" title=" sudden expansion"> sudden expansion</a> </p> <a href="https://publications.waset.org/abstracts/69202/numerical-analysis-of-the-coanda-effect-on-the-classical-interior-ejectors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69202.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">214</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">91</span> Increasing the Frequency of Laser Impulses with Optical Choppers with Rotational Shafts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Virgil-Florin%20Duma">Virgil-Florin Duma</a>, <a href="https://publications.waset.org/abstracts/search?q=Dorin%20Demian"> Dorin Demian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Optical choppers are among the most common optomechatronic devices, utilized in numerous applications, from radiometry to telescopes and biomedical imaging. The classical configuration has a rotational disk with windows with linear margins. This research points out the laser signals that can be obtained with these classical choppers, as well as with another, novel, patented configuration, of eclipse choppers (i.e., with rotational disks with windows with non-linear margins, oriented outwards or inwards). Approximately triangular laser signals can be obtained with eclipse choppers, in contrast to the approximately sinusoidal – with classical devices. The main topic of this work refers to another, novel device, of choppers with shafts of different shapes and with slits of various profiles (patent pending). A significant improvement which can be obtained (with regard to disk choppers) refers to the chop frequencies of the laser signals. Thus, while 1 kHz is their typical limit for disk choppers, with choppers with shafts, a more than 20 times increase in the chop frequency can be obtained with choppers with shafts. Their transmission functions are also discussed, for different types of laser beams.

We have chosen to synthesize and examine silver particles cytotoxicity due to its use in biological applications. The synthesized Ag powders were characterized from the structural, compositional and morphological point of view by using XRD, SEM, and TEM with SAED. In order to determine the influence of the synthesis route on Ag particles cytotoxicity, different sizes of micro and nanosilver synthesized powders were evaluated for their potential toxicity. For the study of their cytotoxicity, cell cycle and apoptosis have been done analysis through flow cytometry on human colon carcinoma cells and mesenchymal stem cells and through the MTT assay, while the viability and the morphological changes of the cells have been evaluated by using cloning studies. The results showed that the synthesized silver nanoparticles have displayed significant cytotoxicity effects on cell cultures. Our synthesized silver powders were found to present toxicity in a synthesis route and time-dependent manners for pyrosol synthesized nanoparticles; whereas a lower cytotoxicity has been measured after cells were treated with silver nanoparticles synthesized through sol-gel method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ag" title="Ag">Ag</a>, <a href="https://publications.waset.org/abstracts/search?q=cytotoxicity" title=" cytotoxicity"> cytotoxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=pyrosol%20method" title=" pyrosol method"> pyrosol method</a>, <a href="https://publications.waset.org/abstracts/search?q=sol-gel%20method" title=" sol-gel method"> sol-gel method</a> </p> <a href="https://publications.waset.org/abstracts/25784/in-vitro-cytotoxicity-study-on-silver-powders-synthesized-via-different-routes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25784.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">594</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">86</span> Efficient Subgoal Discovery for Hierarchical Reinforcement Learning Using Local Computations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adrian%20Millea">Adrian Millea</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In hierarchical reinforcement learning, one of the main issues encountered is the discovery of subgoal states or options (which are policies reaching subgoal states) by partitioning the environment in a meaningful way. This partitioning usually requires an expensive global clustering operation or eigendecomposition of the Laplacian of the states graph. We propose a local solution to this issue, much more efficient than algorithms using global information, which successfully discovers subgoal states by computing a simple function, which we call heterogeneity for each state as a function of its neighbors. Moreover, we construct a value function using the difference in heterogeneity from one step to the next, as reward, such that we are able to explore the state space much more efficiently than say epsilon-greedy. The same principle can then be applied to higher level of the hierarchy, where now states are subgoals discovered at the level below. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=exploration" title="exploration">exploration</a>, <a href="https://publications.waset.org/abstracts/search?q=hierarchical%20reinforcement%20learning" title=" hierarchical reinforcement learning"> hierarchical reinforcement learning</a>, <a href="https://publications.waset.org/abstracts/search?q=locality" title=" locality"> locality</a>, <a href="https://publications.waset.org/abstracts/search?q=options" title=" options"> options</a>, <a href="https://publications.waset.org/abstracts/search?q=value%20functions" title=" value functions"> value functions</a> </p> <a href="https://publications.waset.org/abstracts/134077/efficient-subgoal-discovery-for-hierarchical-reinforcement-learning-using-local-computations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134077.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">171</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">85</span> Solution to Increase the Produced Power in Micro-Hydro Power Plant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Radu%20Pop">Radu Pop</a>, <a href="https://publications.waset.org/abstracts/search?q=Adrian%20Bot"> Adrian Bot</a>, <a href="https://publications.waset.org/abstracts/search?q=Vasile%20Rednic"> Vasile Rednic</a>, <a href="https://publications.waset.org/abstracts/search?q=Emil%20Bruj"> Emil Bruj</a>, <a href="https://publications.waset.org/abstracts/search?q=Oana%20Raita"> Oana Raita</a>, <a href="https://publications.waset.org/abstracts/search?q=Liviu%20Vaida"> Liviu Vaida</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Our research presents a study concerning optimization of water flow capture for micro-hydro power plants in order to increase the energy production.

With this automation concept, we demonstrate that the performance of the micro-hydro power plant could increase, in some flow operating regimes, with approx. 10%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy" title="energy">energy</a>, <a href="https://publications.waset.org/abstracts/search?q=micro-hydro" title=" micro-hydro"> micro-hydro</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20intake" title=" water intake"> water intake</a>, <a href="https://publications.waset.org/abstracts/search?q=fish%20ladder" title=" fish ladder"> fish ladder</a> </p> <a href="https://publications.waset.org/abstracts/89213/solution-to-increase-the-produced-power-in-micro-hydro-power-plant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89213.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">234</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">84</span> Numerical Simulation of Lightning Strike Direct Effects on Aircraft Skin Composite Laminate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Khalil">Muhammad Khalil</a>, <a href="https://publications.waset.org/abstracts/search?q=Nader%20Abuelfoutouh"> Nader Abuelfoutouh</a>, <a href="https://publications.waset.org/abstracts/search?q=Gasser%20Abdelal"> Gasser Abdelal</a>, <a href="https://publications.waset.org/abstracts/search?q=Adrian%20Murphy"> Adrian Murphy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, the direct effects of lightning to aircrafts are of great importance because of the massive use of composite materials. In comparison with metallic materials, composites present several weaknesses for lightning strike direct effects. Especially, their low electrical and thermal conductivities lead to severe lightning strike damage. The lightning strike direct effects are burning, heating, magnetic force, sparking and arcing. As the problem is complex, we investigated it gradually. A magnetohydrodynamics (MHD) model is developed to simulate the lightning strikes in order to estimate the damages on the composite materials. Then, a coupled thermal-electrical finite element analysis is used to study the interaction between the lightning arc and the composite laminate and to investigate the material degradation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composite%20structures" title="composite structures">composite structures</a>, <a href="https://publications.waset.org/abstracts/search?q=lightning%20multiphysics" title=" lightning multiphysics"> lightning multiphysics</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetohydrodynamic%20%28MHD%29" title=" magnetohydrodynamic (MHD)"> magnetohydrodynamic (MHD)</a>, <a href="https://publications.waset.org/abstracts/search?q=coupled%20thermal-electrical%20analysis" title=" coupled thermal-electrical analysis"> coupled thermal-electrical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20plasmas." title=" thermal plasmas."> thermal plasmas.</a> </p> <a href="https://publications.waset.org/abstracts/81848/numerical-simulation-of-lightning-strike-direct-effects-on-aircraft-skin-composite-laminate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81848.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">369</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">83</span> Food Supply Chain Optimization: Achieving Cost Effectiveness Using Predictive Analytics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jayant%20Kumar">Jayant Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Aarcha%20Jayachandran%20Sasikala"> Aarcha Jayachandran Sasikala</a>, <a href="https://publications.waset.org/abstracts/search?q=Barry%20Adrian%20Shepherd"> Barry Adrian Shepherd</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Public Distribution System is a flagship welfare programme of the Government of India with both historical and political significance.

To overcome these difficulties, empirical models based on sampled data can be used instead, namely regression methods typical of machine learning field. They have the ability to learn the trends of a process without any knowledge about its particular physical and chemical laws. Therefore, they are useful for modeling complex processes, such as the free radical polymerization of methyl methacrylate achieved in a batch bulk process. The goal is to generate accurate predictions of monomer conversion, numerical average molecular weight and gravimetrical average molecular weight. This process is associated with non-linear gel and glass effects. For this purpose, an adaptive sampling technique is presented, which can select more samples around the regions where the values have a higher variation. Several machine learning methods are used for the modeling and their performance is compared: support vector machines, k-nearest neighbor, k-nearest neighbor and random forest, as well as an original algorithm, large margin nearest neighbor regression. The suggested method provides very good results compared to the other well-known regression algorithms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=batch%20bulk%20methyl%20methacrylate%20polymerization" title="batch bulk methyl methacrylate polymerization">batch bulk methyl methacrylate polymerization</a>, <a href="https://publications.waset.org/abstracts/search?q=adaptive%20sampling" title=" adaptive sampling"> adaptive sampling</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=large%20margin%20nearest%20neighbor%20regression" title=" large margin nearest neighbor regression"> large margin nearest neighbor regression</a> </p> <a href="https://publications.waset.org/abstracts/54074/performance-comparison-of-different-regression-methods-for-a-polymerization-process-with-adaptive-sampling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54074.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">304</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">81</span> Stakeholder Voices in Digital Evolution: Challenges Faced by SMEs in Automotive Supply Chain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Sharaf">Mohammed Sharaf</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Shokri"> Alireza Shokri</a>, <a href="https://publications.waset.org/abstracts/search?q=Adrian%20Small"> Adrian Small</a>, <a href="https://publications.waset.org/abstracts/search?q=Toby%20Bridges"> Toby Bridges</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper investigates digital transformation challenges in SMEs within the automotive supply chain.

Polyurethane materials are well-known for industrial applications (elastomers and foams used in different insulations and automotive), but they are versatile biocompatible materials with many applications in medicine, as artificial skin for the premature neonate, membrane in the hybrid artificial pancreas, prosthetic heart valves, etc. This study aimed to obtain the physico-chemical characterization of a drug delivery system based on polyurethane microparticles. The synthesis is based on a polyaddition reaction between an aqueous phase (mixture of polyethylene-glycol M=200, 1,4-butanediol and Tween® 20) and an organic phase (lysin-diisocyanate in acetone) combined with simultaneous emulsification. Different active agents (omeprazole, amoxicillin, metoclopramide) were used to verify the release profile of the macromolecular particles in different pH mediums. Zetasizer measurements were performed using an instrument based on two modules: a Vasco size analyzer and a Wallis Zeta potential analyzer (Cordouan Technol., France) in samples that were kept in various solutions with different pH and the maximum absorbance in UV-Vis spectra were collected on a UVi Line 9,400 Spectrophotometer (SI Analytics, Germany). The results of this investigation have revealed that these particles are proper for a prolonged release in gastric medium where they can assure an almost constant concentration of the active agents for 1-2 weeks, while they can be disassembled faster in a medium with neutral pHs, such as the intestinal fluid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lysin-diisocyanate" title="lysin-diisocyanate">lysin-diisocyanate</a>, <a href="https://publications.waset.org/abstracts/search?q=nanostructures" title=" nanostructures"> nanostructures</a>, <a href="https://publications.waset.org/abstracts/search?q=polyurethane" title=" polyurethane"> polyurethane</a>, <a href="https://publications.waset.org/abstracts/search?q=Zetasizer" title=" Zetasizer"> Zetasizer</a> </p> <a href="https://publications.waset.org/abstracts/132694/ph-responsive-carrier-based-on-polymer-particle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132694.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">184</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">79</span> Surface Integrity Improvement for Selective Laser Melting (SLM) Additive Manufacturing of C300 Parts Using Ball Burnishing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adrian%20Travieso%20Disotuar">Adrian Travieso Disotuar</a>, <a href="https://publications.waset.org/abstracts/search?q=J.%20Antonio%20Travieso%20Rodriguez"> J.

Copulas such as the Joe, Gumbel and Student-t copula may be used for this purpose. The copula structure imparts a desired level of tail dependence on the joint distribution of claims from the different LOBs. Alternatively, practitioners may possess historical or simulated data that already exhibit upper tail dependence, through the impact of catastrophe events such as hurricanes or earthquakes. In these circumstances, it is not desirable to induce additional upper tail dependence when modeling the joint distribution of the loss values from the individual LOBs. Instead, it is of interest to accurately assess the degree of tail dependence already present in the data.

However, the assessment of potential impacts from work activities at pre-approval stage may be inaccurate as works methodology and scheduling are yet to be determined. In response, noise and vibration management tools have been developed to refine and supplement the CNVIS as works progress.

This paper proposes the neologism of ‘informed guessing’ as a reformulation of abduction, and also as an approach to education policy analysis. On one side, the signifier ‘informed’ encapsulates the idea that abductive policy analysis needs to be informed by descriptive conceptualization theory to be able to make relations and connections between, and within, observed phenomenon and unobservable general structures. On the other side, the signifier ‘guessing’ captures the cyclical and unsystematic process of abduction. This paper will end with a brief example of utilising ‘informed guessing’ for a policy analysis of school choice lotteries in the United States. <p class="card-text"><strong>Keywords:</strong> <a
