functional surfaces and edges for cutting and forming tools created through the Directed Energy Deposition (DED) technology. In the context of growing challenges in modern engineering, additive technologies, especially DED, present an innovative approach to manufacturing tools for forming and cutting. One of the key features of DED is its ability to precisely and efficiently deposit Fully dense metals from powder feedstock, enabling the creation of complex geometries and optimized designs. Gradually, it becomes an increasingly attractive choice for tool production due to its ability to achieve high precision while simultaneously minimizing waste and material costs. Tools created using DED technology gain significant durability through the utilization of high-performance materials such as nickel alloys and tool steels. For high-temperature applications, Nimonic 80A alloy is applied, while for cold applications, M2 tool steel is used. The addition of ceramic materials, such as tungsten carbide, can significantly increase the tool's resistance. The introduction of functionally graded materials is a significant contribution, opening up new possibilities for gradual changes in the mechanical properties of the tool and optimizing its performance in different sections according to specific requirements. In this work, you will find an overview of individual applications and their utilization in the industry. Microstructural analyses have been conducted, providing detailed insights into the structure of individual components alongside examinations of the mechanical properties and tool life. These analyses offer a deeper understanding of the efficiency and reliability of the created tools, which is a key element for successful development in the field of cutting and forming tools. The production of functional surfaces and edges using DED technology can result in financial savings, as the entire tool doesn't have to be manufactured from expensive special alloys. The tool can be made from common steel, onto which a functional surface from special materials can be applied. Additionally, it allows for tool repairs after wear and tear, eliminating the need for producing a new part and contributing to an overall cost while reducing the environmental footprint. Overall, the combination of DED technology, functionally graded materials, and verified technologies collectively set a new standard for innovative and efficient development of cutting and forming tools in the modern industrial environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=additive%20manufacturing" title="additive manufacturing">additive manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=directed%20energy%20deposition" title=" directed energy deposition"> directed energy deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=DED" title=" DED"> DED</a>, <a href="https://publications.waset.org/abstracts/search?q=laser" title=" laser"> laser</a>, <a href="https://publications.waset.org/abstracts/search?q=cutting%20tools" title=" cutting tools"> cutting tools</a>, <a href="https://publications.waset.org/abstracts/search?q=forming%20tools" title=" forming tools"> forming tools</a>, <a href="https://publications.waset.org/abstracts/search?q=steel" title=" steel"> steel</a>, <a href="https://publications.waset.org/abstracts/search?q=nickel%20alloy" title=" nickel alloy"> nickel alloy</a> </p> <a href="https://publications.waset.org/abstracts/182220/functional-surfaces-and-edges-for-cutting-and-forming-tools-created-using-directed-energy-deposition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182220.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">50</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">74</span> Gender Differences in Attitudes to Technology in Primary Education</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Radek%20Novotn%C3%BD">Radek Novotný</a>, <a href="https://publications.waset.org/abstracts/search?q=Martina%20Man%C4%9Bnov%C3%A1"> Martina Maněnová</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article presents a summary of reviews on gender differences in perception of information and communication technology (ICT) by pupils in primary education.

The current research investigated the impact of illusions of control on positive emotions. There is empirical evidence showing that people are more emotionally attentive to losses than to gains. Hence, we expected that, compared to gains, losses in illusory control would have a stronger impact on positive emotions. The results of two experimental studies support this assumption: Participants who experienced gains in illusory control showed no substantial change in positive emotions. However, positive emotions decreased when they perceived a loss in illusory control. These results suggest that a loss of illusory control (but not a gain thereof) mediates the impact of the situation on individuals’ positive emotions. Implications for emotion theory and practice are discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cognitive%20appraisal" title="cognitive appraisal">cognitive appraisal</a>, <a href="https://publications.waset.org/abstracts/search?q=control" title=" control"> control</a>, <a href="https://publications.waset.org/abstracts/search?q=illusions" title=" illusions"> illusions</a>, <a href="https://publications.waset.org/abstracts/search?q=optimism" title=" optimism"> optimism</a>, <a href="https://publications.waset.org/abstracts/search?q=positive%20emotions" title=" positive emotions"> positive emotions</a> </p> <a href="https://publications.waset.org/abstracts/29489/can-illusions-of-control-make-us-happy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29489.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">641</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">72</span> Transformation of the Postindustrial City - The Conversion of a Smelter in Restaurant with a Panoramic Views</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Martina%20Perinkova">Martina Perinkova</a>, <a href="https://publications.waset.org/abstracts/search?q=Lenka%20Kolarcikova"> Lenka Kolarcikova</a>, <a href="https://publications.waset.org/abstracts/search?q=Marketa%20Twrda"> Marketa Twrda </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Ostrava there are a lot of former post-industrial areas and areas that have gradually through conversions and their subsequent reuse.

The diffusion of innovations theory, which was written by E. M. Rogers, captures the processes of innovation adoption. The research method derived from this theory and the Rogers’ questionnaire focused on the diffusion of innovations was used as the basic research method. The research sample consisted of elementary school teachers. The comparison of results with the Rogers’ results shows that among the teachers in the research sample the so-called early majority, as well as the overall division of the data, was rather central (early adopter, early majority, and later majority). The teachers very rarely appeared on the edge positions (innovator, laggard).

Chromium as an indelible non-volatile trace element of raw materials occurs in cement clinker in the trivalent or hexavalent form. Hexavalent form of chromium is harmful and allergenic having very high water solubility and thus can easily come into contact with the human skin. The paper is aimed at analyzing the content of total chromium in Portland cements and leaching rate of hexavalent chromium in various leachants: Deionized water, Britton-Robinson buffer, used to simulate the natural environment, and hydrochloric acid (HCl). The concentration of total chromium in Portland cement samples was in a range from 173.2 to 218.5 mg/kg. The content of dissolved hexavalent chromium ranged 0.23-3.19, 2.0-5.78 and 8.88-16.25 mg/kg in deionized water, Britton-Robinson solution and hydrochloric acid, respectively. The calculated leachable fraction of Cr(VI) from cement samples was observed in the range 0.1--7.58 %. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environment" title="environment">environment</a>, <a href="https://publications.waset.org/abstracts/search?q=cement" title=" cement"> cement</a>, <a href="https://publications.waset.org/abstracts/search?q=chromium" title=" chromium"> chromium</a>, <a href="https://publications.waset.org/abstracts/search?q=leaching" title=" leaching"> leaching</a> </p> <a href="https://publications.waset.org/abstracts/45262/chromium-leaching-study-of-cements-in-various-environments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45262.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">277</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">67</span> Culture and Deviance Told by Skin: Non Verbal Communication of Tattoos</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andreas%20Aceranti">Andreas Aceranti</a>, <a href="https://publications.waset.org/abstracts/search?q=Simonetta%20Vernocchi"> Simonetta Vernocchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Marco%20Colorato"> Marco Colorato</a>, <a href="https://publications.waset.org/abstracts/search?q=Ludwig%20Conistabile"> Ludwig Conistabile</a>, <a href="https://publications.waset.org/abstracts/search?q=Martina%20Falappi"> Martina Falappi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study was born out of the necessity to delve into and understand the intricate world of tattoos, a millenary art that lays its foundation, although sometimes complex, for effective non-verbal communication. What is most astonishing about a phenomenon such as irreversibly branding the skin, which at first glance may appear superficial, especially in the eyes of those who do not fully understand its meaning, is the fact that it is actually one of the most enduring forms of communication: body modification through tattoos or ornamental dyes indicated the wearer's membership in a particular ethnic group, social class or religious community. Even within crime-based aggregations, tattoos had (and still have) the purpose of conveying one's affiliation to a particular group, thus making one's criminal identity known. The profession of a language and cultural mediator teaches that it is essential to be able to read between the lines to grasp all those aspects that words alone do not convey. Tattooing, therefore, becomes a tool of analysis and a language that is not secondary to be taken into account for an in-depth reading of the reality that surrounds us and of cultures different from our own. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tattoo" title="tattoo">tattoo</a>, <a href="https://publications.waset.org/abstracts/search?q=cultural%20tattoos" title=" cultural tattoos"> cultural tattoos</a>, <a href="https://publications.waset.org/abstracts/search?q=tattooing" title=" tattooing"> tattooing</a>, <a href="https://publications.waset.org/abstracts/search?q=non%20verbal%20communication" title=" non verbal communication"> non verbal communication</a> </p> <a href="https://publications.waset.org/abstracts/160310/culture-and-deviance-told-by-skin-non-verbal-communication-of-tattoos" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160310.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">204</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">66</span> Student and Group Activity Level Assessment in the ELARS Recommender System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Martina%20Holenko%20Dlab">Martina Holenko Dlab</a>, <a href="https://publications.waset.org/abstracts/search?q=Natasa%20Hoic-Bozic"> Natasa Hoic-Bozic</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents an original approach to student and group activity level assessment that relies on certainty factors theory. Activity level is used to represent quantity and continuity of student’s contributions in individual and collaborative e‑learning activities (e‑tivities) and is calculated to assist teachers in assessing quantitative aspects of student's achievements. Calculated activity levels are also used to raise awareness and provide recommendations during the learning process. The proposed approach was implemented within the educational recommender system ELARS and validated using data obtained from e‑tivity realized during a blended learning course. The results showed that the proposed approach can be used to estimate activity level in the context of e-tivities realized using Web 2.0 tools as well as to facilitate the assessment of quantitative aspect of students’ participation in e‑tivities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=assessment" title="assessment">assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=ELARS" title=" ELARS"> ELARS</a>, <a href="https://publications.waset.org/abstracts/search?q=e-learning" title=" e-learning"> e-learning</a>, <a href="https://publications.waset.org/abstracts/search?q=recommender%20systems" title=" recommender systems"> recommender systems</a>, <a href="https://publications.waset.org/abstracts/search?q=student%20model" title=" student model"> student model</a> </p> <a href="https://publications.waset.org/abstracts/64885/student-and-group-activity-level-assessment-in-the-elars-recommender-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64885.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">262</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> Critical Design - Concepts, Methods and Practices for Innovative Societal Relationships</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Martina%20Maria%20Keitsch">Martina Maria Keitsch</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Critical Design (CD) confronts traditional design practice. Instead of reproducing and reinforcing contemporary perceptions of products and services, CD seeks to challenge them with the goal to stimulate debates and visions on societal innovation. CD methods comprise, among other narratives and design of critical objects. The oral presentation is based on a study that discusses concepts, methods, and applications of CD links CD to traditional design, and identifies CD benefits and challenges for design research and practice. The objective of the study is to introduce CD as an alternative for design researchers and practitioners supplementing commercially oriented design approaches. The study utilizes a literature review on CD concepts and methods based on current publications and online documents and illustrates CD practice with help of selected case studies. Findings of the study indicate that CD contribute, among others, to create new societal roles for designers, foster innovative relationships between designers and users, and encourage creativity through imaginative aesthetics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=critical%20design" title="critical design">critical design</a>, <a href="https://publications.waset.org/abstracts/search?q=postmodern%20design%20theories" title=" postmodern design theories"> postmodern design theories</a>, <a href="https://publications.waset.org/abstracts/search?q=narratives" title=" narratives"> narratives</a>, <a href="https://publications.waset.org/abstracts/search?q=rhizome" title=" rhizome"> rhizome</a> </p> <a href="https://publications.waset.org/abstracts/142668/critical-design-concepts-methods-and-practices-for-innovative-societal-relationships" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142668.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">64</span> Population Diversity of Dalmatian Pyrethrum Based on Pyrethrin Content and Composition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Filip%20Varga">Filip Varga</a>, <a href="https://publications.waset.org/abstracts/search?q=Nina%20Jeran"> Nina Jeran</a>, <a href="https://publications.waset.org/abstracts/search?q=Martina%20Biosic"> Martina Biosic</a>, <a href="https://publications.waset.org/abstracts/search?q=Zlatko%20Satovic"> Zlatko Satovic</a>, <a href="https://publications.waset.org/abstracts/search?q=Martina%20Grdisa"> Martina Grdisa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dalmatian pyrethrum (Tanacetum cinerariifolium /Trevir./ Sch. Bip.), a species endemic to the eastern Adriatic coastline, is the source of natural insecticide pyrethrin. Pyrethrin is a mixture of six compounds (pyrethrin I and II, cinerin I and II, jasmolin I and II) that exhibits high insecticidal activity with no detrimental effects to the environment. A recently optimized matrix-solid phase dispersion method (MSPD), using florisil as the sorbent, acetone-ethyl acetate (1:1, v/v) as the elution solvent, and sodium sulfate anhydrous as the drying agent was utilized to extract the pyrethrins from 10 wild populations (20 individuals per population) distributed along the Croatian coast. All six components in the extracts were qualitatively and quantitatively determined by high-performance liquid chromatography with a diode array detector (HPLC-DAD). Pearson’s correlation index was calculated between pyrethrin compounds, and differences between the populations using the analysis of variance were tested. Additionally, the correlation of each pyrethrin component with spatio-ecological variables (bioclimate, soil properties, elevation, solar radiation, and distance from the coastline) was calculated. Total pyrethrin content ranged from 0.10% to 1.35% of dry flower weight, averaging 0.58% across all individuals. Analysis of variance revealed significant differences between populations based on all six pyrethrin compounds and total pyrethrin content. On average, the lowest total pyrethrin content was found in the population from Pelješac peninsula (0.22% of dry flower weight) in which total pyrethrin content lower than 0.18% was detected in 55% of the individuals. The highest average total pyrethrin content was observed in the population from island Zlarin (0.87% of dry flower weight), in which total pyrethrin content higher than 1.00% was recorded in only 30% of the individuals. Pyrethrin I/pyrethrin II ratio as a measure of extract quality ranged from 0.21 (population from the island Čiovo) to 5.88 (population from island Mali Lošinj) with an average of 1.77 across all individuals. By far, the lowest quality of extracts was found in the population from Mt. Biokovo (pyrethrin I/II ratio lower than 0.72 in 40% of individuals) due to the high pyrethrin II content typical for this population. Pearson’s correlation index revealed a highly significant positive correlation between pyrethrin I content and total pyrethrin content and a strong negative correlation between pyrethrin I and pyrethrin II. The results of this research clearly indicate high intra- and interpopulation diversity of Dalmatian pyrethrum with regards to pyrethrin content and composition. The information obtained has potential use in plant genetic resources conservation and biodiversity monitoring. Possibly the largest potential lies in designing breeding programs aimed at increasing pyrethrin content in commercial breeding lines and reintroduction in agriculture in Croatia.

System refinements were based on experience and interaction data gathered during class observations. In addition to implemented improvements, the data were used to outline possible improvements and deficiencies of the system that should be addressed in the next phase of the <em>SCOLLAm [in]Form</em> development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adaptation" title="adaptation">adaptation</a>, <a href="https://publications.waset.org/abstracts/search?q=collaborative%20learning" title=" collaborative learning"> collaborative learning</a>, <a href="https://publications.waset.org/abstracts/search?q=educational%20technology" title=" educational technology"> educational technology</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20learning" title=" mobile learning"> mobile learning</a>, <a href="https://publications.waset.org/abstracts/search?q=tablet%20computers" title=" tablet computers"> tablet computers</a> </p> <a href="https://publications.waset.org/abstracts/64887/a-design-based-approach-to-developing-a-mobile-learning-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64887.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">272</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> Reuse of Huge Industrial Areas</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Martina%20Perinkova">Martina Perinkova</a>, <a href="https://publications.waset.org/abstracts/search?q=Lenka%20Kolarcikova"> Lenka Kolarcikova</a>, <a href="https://publications.waset.org/abstracts/search?q=Marketa%20Twrda"> Marketa Twrda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Brownfields are one of the most important problems that must be solved by today's cities. The topic of this article is description of developing a comprehensive transformation of post-industrial area of the former iron factory national cultural heritage Lower Vítkovice. City of Ostrava used to be industrial superpower of the Czechoslovak Republic, especially in the area of coal mining and iron production, after declining industrial production and mining in the 80s left many unused areas of former factories generally brownfields and backfields. Since the late 90s we are observing how the city officials or private entities seeking to remedy this situation. Regeneration of brownfields is a very expensive and long-term process. The area is now rebuilt for tourists and residents of the city in the entertainment, cultural, and social center. It was necessary do the reconstruction of the industrial monuments. Equally important was the construction of new buildings, which helped reusing of the entire complex. This is a unique example of transformation of technical monuments and completion of necessary new objects, so that the area could start working again and reintegrate back into the urban system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brown%20fields" title="brown fields">brown fields</a>, <a href="https://publications.waset.org/abstracts/search?q=conversion" title=" conversion"> conversion</a>, <a href="https://publications.waset.org/abstracts/search?q=historical%20and%20industrial%20buildings" title=" historical and industrial buildings"> historical and industrial buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=reconstruction" title=" reconstruction "> reconstruction </a> </p> <a href="https://publications.waset.org/abstracts/34043/reuse-of-huge-industrial-areas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34043.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">329</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">61</span> Predicting Machine-Down of Woodworking Industrial Machines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Matteo%20Calabrese">Matteo Calabrese</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20Cimmino"> Martin Cimmino</a>, <a href="https://publications.waset.org/abstracts/search?q=Dimos%20Kapetis"> Dimos Kapetis</a>, <a href="https://publications.waset.org/abstracts/search?q=Martina%20Manfrin"> Martina Manfrin</a>, <a href="https://publications.waset.org/abstracts/search?q=Donato%20Concilio"> Donato Concilio</a>, <a href="https://publications.waset.org/abstracts/search?q=Giuseppe%20Toscano"> Giuseppe Toscano</a>, <a href="https://publications.waset.org/abstracts/search?q=Giovanni%20Ciandrini"> Giovanni Ciandrini</a>, <a href="https://publications.waset.org/abstracts/search?q=Giancarlo%20Paccapeli"> Giancarlo Paccapeli</a>, <a href="https://publications.waset.org/abstracts/search?q=Gianluca%20Giarratana"> Gianluca Giarratana</a>, <a href="https://publications.waset.org/abstracts/search?q=Marco%20Siciliano"> Marco Siciliano</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Forlani"> Andrea Forlani</a>, <a href="https://publications.waset.org/abstracts/search?q=Alberto%20Carrotta"> Alberto Carrotta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper we describe a machine learning methodology for Predictive Maintenance (PdM) applied on woodworking industrial machines. PdM is a prominent strategy consisting of all the operational techniques and actions required to ensure machine availability and to prevent a machine-down failure. One of the challenges with PdM approach is to design and develop of an embedded smart system to enable the health status of the machine. The proposed approach allows screening simultaneously multiple connected machines, thus providing real-time monitoring that can be adopted with maintenance management. This is achieved by applying temporal feature engineering techniques and training an ensemble of classification algorithms to predict Remaining Useful Lifetime of woodworking machines. The effectiveness of the methodology is demonstrated by testing an independent sample of additional woodworking machines without presenting machine down event. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=predictive%20maintenance" title="predictive maintenance">predictive maintenance</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=connected%20machines" title=" connected machines"> connected machines</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title=" artificial intelligence"> artificial intelligence</a> </p> <a href="https://publications.waset.org/abstracts/98461/predicting-machine-down-of-woodworking-industrial-machines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98461.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">226</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">60</span> Soil Surface Insect Diversity of Tobacco Agricultural Ecosystem in Imogiri, Bantul District of Yogyakarta Special Region, Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Martina%20Faika%20Harianja">Martina Faika Harianja</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahtamal"> Zahtamal</a>, <a href="https://publications.waset.org/abstracts/search?q=Indah%20Nuraini"> Indah Nuraini</a>, <a href="https://publications.waset.org/abstracts/search?q=Septi%20Mutia%20Handayani"> Septi Mutia Handayani</a>, <a href="https://publications.waset.org/abstracts/search?q=R.%20C.%20Hidayat%20Soesilohadi"> R.

Indeed, particles inside equipment can be driven by the gas flow and accumulate in places where the velocity is low. As they constitute a potential ignition hazard, particular attention is paid to the presence of particles in the oxygen industry. Indeed, the heat release from ignited particles may damage the equipment and even result in a loss of integrity. The objective of this work is to support the development of new design criteria. Studying the thermomechanical behavior of this equipment, thanks to numerical simulations, allows us to test the influence of various operating parameters (oxygen pressure, wall thickness, initial operating temperature, nature of the metal, etc.). Therefore, in this study, we propose a numerical model that describes the thermomechanical behavior of various pressurized installations heated locally by the combustion of small particles.

Methods: The present study was conducted using mixed methods, combining a concurrent triangulation and sequential explanatory design. First, 3027 pictures posted on Instagram using #Orthorexia were analyzed. Then, a questionnaire about Instagram use related to ON was completed entirely by 185 respondents. These two quantitative data sources were statistically analyzed and triangulated afterwards. Finally, 9 interviews were conducted, to more deeply investigate what is being said about ON on Instagram and what the motivations to post about it are. Results: Four main categories of pictures were found to be represented in Instagram posts about ON: ‘food’, ‘people’, ‘text’, and ‘other.’ Savory and unprocessed food was most highly represented within the food category, and pictures of people were mostly pictures of the account holder. People who self-identify as having ON were more likely to post about ON, and they were significantly more likely to post about ‘food’, ‘people’ and ‘text.’ The goal of the posts was to raise awareness around ON, as well as to provide support for people who believe to be suffering from it. Conclusion: Since the conversation around ON on Instagram is supportive, it could be beneficial to consider Instagram use in the treatment of ON. However, more research is needed on a larger scale. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=orthorexia%20nervosa" title="orthorexia nervosa">orthorexia nervosa</a>, <a href="https://publications.waset.org/abstracts/search?q=Instagram" title=" Instagram"> Instagram</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20media" title=" social media"> social media</a>, <a href="https://publications.waset.org/abstracts/search?q=disordered%20eating" title=" disordered eating"> disordered eating</a> </p> <a href="https://publications.waset.org/abstracts/117109/a-mixed-methods-study-aimed-at-exploring-the-conceptualization-of-orthorexia-nervosa-on-instagram" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117109.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">138</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">56</span> Culturally Responsive Teaching for Learner Diversity in Czech Schools: A Literature Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ntite%20Orji%20Kalu">Ntite Orji Kalu</a>, <a href="https://publications.waset.org/abstracts/search?q=Martina%20Kurowski"> Martina Kurowski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Until recently, the Czech Republic had an educational system dominated by indigenous people, who accounted for 95% of the school population. With the increasing influx of migrants and foreign students, especially from outside European Union, came a great disparity among the quality of learners and their learning needs and consideration for the challenges associated with being a minority and living within a foreign culture. This has prompted the research into ways of tailoring the educational system to meet the rising demand of learning styles and needs for the diverse learners in the Czech classrooms. Literature is reviewed regarding the various ways to accommodate the international students considering racial differences, focusing on theoretical approach and pedagogical principles. This study examines the compulsory educational system of the Czech Republic and the position and responsibility of the teacher in fostering a culturally sensitive and inclusive learning environment. Descriptive and content analysis is relied upon for this study. Recommendations are made for stakeholders to imbibe a more responsive environment that enhances the cultural and social integration of all learners. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=culturally%20responsive%20teaching" title="culturally responsive teaching">culturally responsive teaching</a>, <a href="https://publications.waset.org/abstracts/search?q=cultural%20competence" title=" cultural competence"> cultural competence</a>, <a href="https://publications.waset.org/abstracts/search?q=diversity" title=" diversity"> diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=learners" title=" learners"> learners</a>, <a href="https://publications.waset.org/abstracts/search?q=inclusive%20education" title=" inclusive education"> inclusive education</a>, <a href="https://publications.waset.org/abstracts/search?q=Czech%20schools" title=" Czech schools"> Czech schools</a> </p> <a href="https://publications.waset.org/abstracts/141784/culturally-responsive-teaching-for-learner-diversity-in-czech-schools-a-literature-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141784.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">146</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">55</span> Maternal Smoking and Risk of Childhood Overweight and Obesity: A Meta-Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Martina%20Kanciruk">Martina Kanciruk</a>, <a href="https://publications.waset.org/abstracts/search?q=Jac%20J.%20W.%20Andrews"> Jac J.

This paper describes experimental investigation on the response of new advanced materials to low and high velocity load. Blast wave energy absorbers were designed using two types of porous lightweight raw particle materials based on expanded glass and ceramics with dimensions of 0.5-1 mm, combined with polymeric binder. The effect of binder amount on the static and dynamic properties of designed materials was observed. Prism shaped specimens were prepared and loaded to obtain physico-mechanical parameters – bulk density, compressive and flexural strength under quasistatic load, the dynamic response was determined using Split Hopkinson Pressure bar apparatus. Numerical investigation of the material behaviour in sandwich structure was performed using implicit/explicit solver LS-Dyna. As the last step, the developed material was used as the interlayer of blast resistant litter bin, and it´s functionality was verified by real field blast tests. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blast%20energy%20absorber" title="blast energy absorber">blast energy absorber</a>, <a href="https://publications.waset.org/abstracts/search?q=SHPB" title=" SHPB"> SHPB</a>, <a href="https://publications.waset.org/abstracts/search?q=expanded%20glass" title=" expanded glass"> expanded glass</a>, <a href="https://publications.waset.org/abstracts/search?q=expanded%20ceramics" title=" expanded ceramics"> expanded ceramics</a> </p> <a href="https://publications.waset.org/abstracts/26570/advanced-energy-absorbers-used-in-blast-resistant-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26570.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">458</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">52</span> E-Consumers’ Attribute Non-Attendance Switching Behavior: Effect of Providing Information on Attributes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leonard%20Maaya">Leonard Maaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Michel%20Meulders"> Michel Meulders</a>, <a href="https://publications.waset.org/abstracts/search?q=Martina%20Vandebroek"> Martina Vandebroek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Discrete Choice Experiments (DCE) are used to investigate how product attributes affect decision-makers’ choices. In DCEs, choice situations consisting of several alternatives are presented from which choice-makers select the preferred alternative. Standard multinomial logit models based on random utility theory can be used to estimate the utilities for the attributes. The overarching principle in these models is that respondents understand and use all the attributes when making choices. However, studies suggest that respondents sometimes ignore some attributes (commonly referred to as Attribute Non-Attendance/ANA). The choice modeling literature presents ANA as a static process, i.e., respondents’ ANA behavior does not change throughout the experiment. However, respondents may ignore attributes due to changing factors like availability of information on attributes, learning/fatigue in experiments, etc. We develop a dynamic mixture latent Markov model to model changes in ANA when information on attributes is provided. The model is illustrated on e-consumers’ webshop choices. The results indicate that the dynamic ANA model describes the behavioral changes better than modeling the impact of information using changes in parameters. Further, we find that providing information on attributes leads to an increase in the attendance probabilities for the investigated attributes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=choice%20models" title="choice models">choice models</a>, <a href="https://publications.waset.org/abstracts/search?q=discrete%20choice%20experiments" title=" discrete choice experiments"> discrete choice experiments</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20models" title=" dynamic models"> dynamic models</a>, <a href="https://publications.waset.org/abstracts/search?q=e-commerce" title=" e-commerce"> e-commerce</a>, <a href="https://publications.waset.org/abstracts/search?q=statistical%20modeling" title=" statistical modeling"> statistical modeling</a> </p> <a href="https://publications.waset.org/abstracts/117427/e-consumers-attribute-non-attendance-switching-behavior-effect-of-providing-information-on-attributes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117427.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">140</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">51</span> Azaridachta Indica (Neem) Seed Oil Effect in Experimental Arthritis – Biochemical Parameters Assessment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sasan%20Khademnematolahi">Sasan Khademnematolahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Kevine%20Kamga%20Silihe"> Kevine Kamga Silihe</a>, <a href="https://publications.waset.org/abstracts/search?q=Katar%C3%ADna%20Pru%C5%BEinsk%C3%A1"> Katarína Pružinská</a>, <a href="https://publications.waset.org/abstracts/search?q=Martina%20Chrastina"> Martina Chrastina</a>, <a href="https://publications.waset.org/abstracts/search?q=Elisabeth%20Louise%20Ndjengue%20Mindang"> Elisabeth Louise Ndjengue Mindang</a>, <a href="https://publications.waset.org/abstracts/search?q=Franti%C5%A1ek%20Dr%C3%A1fi"> František Dráfi</a>, <a href="https://publications.waset.org/abstracts/search?q=Katar%C3%ADna%20Bauerov%C3%A1"> Katarína Bauerová</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: In ethnomedicine, plant parts and compounds are traditionally utilized to treat many disorders. Azadirachta indica, known as Neem, has been traditionally used in medicinal practices. Neem has various pharmaceutical activities, such as antioxidant and anti-inflammatory, due to the content of bioactive compounds like nimbolide, azadirachtin, and gedunin.Through its effect on pathological inflammatory processes, supplementation with it could alleviate the symptoms of rheumatoid arthritis (RA). Methods: This research aimed to assess Neem seed oil's impact on rats with adjuvant arthritis. Three doses in monotherapy and two in combination with methotrexate (MTX) have been studied and their effect was compared. Neem p.o. doses of 100, 200, and 300 mg/kg and MTX p.o. doses of 0.3 mg/kg were examined. After clinical parameters assessment, biochemical analysis was performed in plasma. Results: During the acute phase of the experimental arthritis (Day21), levels of MMP-9, MCP-1 and cytokines IL-1beta and IL-17A were measured. The positive results of inflammatory mediators evaluation in plasma encourage additional analysis also in related tissues to prove if Neem seed oil can be used as an adjuvant therapy for RA. Conclusion: In this study, the combination therapy of Neem with MTX was most effective from all therapies investigated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adjuvant" title="adjuvant">adjuvant</a>, <a href="https://publications.waset.org/abstracts/search?q=neem" title=" neem"> neem</a>, <a href="https://publications.waset.org/abstracts/search?q=methotrexate" title=" methotrexate"> methotrexate</a>, <a href="https://publications.waset.org/abstracts/search?q=arthritis" title=" arthritis"> arthritis</a> </p> <a href="https://publications.waset.org/abstracts/186176/azaridachta-indica-neem-seed-oil-effect-in-experimental-arthritis-biochemical-parameters-assessment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186176.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">46</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> Influence of Dry-Film Lubricants on Bond Strength and Corrosion Behaviour of 6xxx Aluminium Alloy Adhesive Joints for Automotive Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ralph%20Gruber">Ralph Gruber</a>, <a href="https://publications.waset.org/abstracts/search?q=Martina%20Hafner"> Martina Hafner</a>, <a href="https://publications.waset.org/abstracts/search?q=Theresia%20Greunz"> Theresia Greunz</a>, <a href="https://publications.waset.org/abstracts/search?q=Christian%20Reisecker"> Christian Reisecker</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Stifter"> David Stifter</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The application of dry lubricant on aluminium for automotive industry is indispensable for a high-quality forming behaviour. To provide a short production time those forming aids will not be removed during the joining step. The aim of this study was the characterization of the influence of dry lubricants on the bond strength and the corrosion resistance of an 6xxx aluminium alloy for automotive applications. For this purpose, samples with a well-defined surface were lubricated with 1 g/m² dry lubricant and joined with a commercial thermosetting 1K-epoxy structural adhesive. The bond strength was characterized by means of lap shear test. To evaluate the corrosion resistance of the adhered aluminium samples an immersion test in 5 w% NaCl-solution was used. Based on fracture pattern analysis, the corrosion behaviour could be described. Dissolved corrosion products were examined using ICP-MS and NMR. By means of SEM/EDX the elementary composition of precipitated solids was determined. The results showed a dry lubricant independent bond strength for standard testing conditions.

These graffiti are visible on the walls of houses, all around the camp, and they convey messages of protest but also of hope or claim about the complex political situation in the occupied territories. These graffiti can be then interpreted as political and politicized semiotic resources. In this paper, after having introduced the political situation of the Palestinian Territories in a historical perspective, we will question a specific dimension of these writings, i.e., their multilingual and ideological aspect. To do this, we will focus on ethnographic fieldwork on Deheishe refugee camp and we will draw on the theoretical framework of the critical communication studies which assert that language practices are not neutral and that they need to be understood through the lens of the historical context of production, crossing space and time. By analysing the relationship between the discursive constructions of the messages and the languages used, we will point out some of the possible reasons and functions of the presence of these multilingual discursive productions. We will show that if, on the one hand, these graffiti confirm the huge presence of Western actors in the region, on the other hand, they attest the presence of an international movement against the Israeli occupation and against other struggles as well. Concluding, we will argue that multilingualism certainly represents a diversification of the linguistic landscape and that it gives a transnational and political dimension to the graffiti. <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=graffiti" title=" graffiti"> graffiti</a>, <a href="https://publications.waset.org/abstracts/search?q=multilingualism" title=" multilingualism"> multilingualism</a>, <a href="https://publications.waset.org/abstracts/search?q=Palestine" title=" Palestine"> Palestine</a>, <a href="https://publications.waset.org/abstracts/search?q=transnationalism" title=" transnationalism"> transnationalism</a> </p> <a href="https://publications.waset.org/abstracts/87852/multilingual-and-ideological-graffiti-in-palestine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87852.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">48</span> The Photocatalytic Degradation of Acid Blue 25 Dye by Polypyrrole/Titanium Dioxide and Polypyrrole/Zinc Oxide Composites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ljerka%20Kratofil%20Krehula">Ljerka Kratofil Krehula</a>, <a href="https://publications.waset.org/abstracts/search?q=Martina%20Perlog"> Martina Perlog</a>, <a href="https://publications.waset.org/abstracts/search?q=Jasmina%20Stjepanovi%C4%87"> Jasmina Stjepanović</a>, <a href="https://publications.waset.org/abstracts/search?q=Vanja%20Gilja"> Vanja Gilja</a>, <a href="https://publications.waset.org/abstracts/search?q=Marijana%20Kralji%C4%87%20Rokovi%C4%87"> Marijana Kraljić Roković</a>, <a href="https://publications.waset.org/abstracts/search?q=Zlata%20Hrnjak-Murgi%C4%87"> Zlata Hrnjak-Murgić</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The composite preparation of titanium dioxide and zinc oxide photocatalysts with the conductive polymers gives the opportunity to carry out the catalysis reactions not only under UV light but also under visible light. Such processes may efficiently use sunlight in degradation of different organic pollutants and present new design for wastewater treatment. The paper presents the preparation procedure, material characteristics and photocatalytic efficiency of polypyrrole/titanium dioxide and polypyrrole/zinc oxide composites (PPy/TiO2 and PPy/ZnO). The obtained composite samples were characterized by Fourier transform infrared spectroscopy (FTIR), UV-Vis spectroscopy and thermogravimetric analysis (TGA). The photocatalytic efficiency of the samples was determined following the decomposition of Acid Blue 25 dye (AB 25) under UV and visible light by UV/Vis spectroscopy. The efficiency of degradation is determined by total organic carbon content (TOC) after photocatalysis processes. The results show enhanced photocatalytic efficiency of the samples under visible light, so the prepared composite samples are recognized as efficient catalysts in degradation process of AB 25 dye. It can be concluded that the preparation of TiO2 or ZnO composites with PPy can serve as a very efficient method for the improvement of TiO2 and ZnO photocatalytic performance under visible light. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composite" title="composite">composite</a>, <a href="https://publications.waset.org/abstracts/search?q=photocatalysis" title=" photocatalysis"> photocatalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=polypyrrole" title=" polypyrrole"> polypyrrole</a>, <a href="https://publications.waset.org/abstracts/search?q=titanium%20dioxide" title=" titanium dioxide"> titanium dioxide</a>, <a href="https://publications.waset.org/abstracts/search?q=zinc%20oxide" title=" zinc oxide"> zinc oxide</a> </p> <a href="https://publications.waset.org/abstracts/79349/the-photocatalytic-degradation-of-acid-blue-25-dye-by-polypyrroletitanium-dioxide-and-polypyrrolezinc-oxide-composites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79349.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">486</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> Bayesian Borrowing Methods for Count Data: Analysis of Incontinence Episodes in Patients with Overactive Bladder</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Akalu%20Banbeta">Akalu Banbeta</a>, <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20Lesaffre"> Emmanuel Lesaffre</a>, <a href="https://publications.waset.org/abstracts/search?q=Reynaldo%20Martina"> Reynaldo Martina</a>, <a href="https://publications.waset.org/abstracts/search?q=Joost%20Van%20Rosmalen"> Joost Van Rosmalen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Including data from previous studies (historical data) in the analysis of the current study may reduce the sample size requirement and/or increase the power of analysis. The most common example is incorporating historical control data in the analysis of a current clinical trial. However, this only applies when the historical control dataare similar enough to the current control data. Recently, several Bayesian approaches for incorporating historical data have been proposed, such as the meta-analytic-predictive (MAP) prior and the modified power prior (MPP) both for single control as well as for multiple historical control arms. Here, we examine the performance of the MAP and the MPP approaches for the analysis of (over-dispersed) count data. To this end, we propose a computational method for the MPP approach for the Poisson and the negative binomial models. We conducted an extensive simulation study to assess the performance of Bayesian approaches. Additionally, we illustrate our approaches on an overactive bladder data set. For similar data across the control arms, the MPP approach outperformed the MAP approach with respect to thestatistical power. When the means across the control arms are different, the MPP yielded a slightly inflated type I error (TIE) rate, whereas the MAP did not. In contrast, when the dispersion parameters are different, the MAP gave an inflated TIE rate, whereas the MPP did not.We conclude that the MPP approach is more promising than the MAP approach for incorporating historical count data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=count%20data" title="count data">count data</a>, <a href="https://publications.waset.org/abstracts/search?q=meta-analytic%20prior" title=" meta-analytic prior"> meta-analytic prior</a>, <a href="https://publications.waset.org/abstracts/search?q=negative%20binomial" title=" negative binomial"> negative binomial</a>, <a href="https://publications.waset.org/abstracts/search?q=poisson" title=" poisson"> poisson</a> </p> <a href="https://publications.waset.org/abstracts/150987/bayesian-borrowing-methods-for-count-data-analysis-of-incontinence-episodes-in-patients-with-overactive-bladder" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150987.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">117</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> Classification of Business Models of Italian Bancassurance by Balance Sheet Indicators</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Bellucci">Andrea Bellucci</a>, <a href="https://publications.waset.org/abstracts/search?q=Martina%20Tofi"> Martina Tofi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of paper is to analyze business models of bancassurance in Italy for life business. The life insurance business is very developed in the Italian market and banks branches have 80% of the market share. Given its maturity, the life insurance market needs to consolidate its organizational form to allow for the development of non-life business, which nowadays collects few premiums but represents a great opportunity to enlarge the market share of bancassurance using its strength in the distribution channel while the market share of independent agents is decreasing. Starting with the main business model of bancassurance for life business, this paper will analyze the performances of life companies in the Italian market by balance sheet indicators and by main discriminant variables of business models. The study will observe trends from 2013 to 2015 for the Italian market by exploiting a database managed by Associazione Nazionale delle Imprese di Assicurazione (ANIA). The applied approach is based on a bottom-up analysis starting with variables and indicators to define business models’ classification. The statistical classification algorithm proposed by Ward is employed to design business models’ profiles. Results from the analysis will be a representation of the main business models built by their profile related to indicators. In that way, an unsupervised analysis is developed that has the limit of its judgmental dimension based on research opinion, but it is possible to obtain a design of effective business models. <p
