This means, for example, that equity managers have been forced to adhere strictly to a benchmark with static or relatively stable components, such as the SP 500 or the Russell 3000. This means that the portfolio’s exposures to all risk factors should mimic as closely as possible the corresponding exposures of the benchmark. The main risk factor, of course, is the market itself. Effectively, a long-only portfolio would be constrained to have a beta 1. More recently, however, managers have been given greater discretion to adjust their portfolio’s risk exposures (in particular, the beta of their portfolio) dynamically to match the manager’s beliefs about future performance of the risk factors themselves. This freedom translates into the manager’s ability to adjust the portfolio’s beta dynamically. These strategies have come to be known as smart beta strategies. Adjusting beta dynamically amounts to attempting to "time" the market; that is, to increase exposure when one anticipates that the market will rise, and to decrease it when one anticipates that the market will fall. Traditionally, market timing has been believed to be impossible to perform effectively and consistently. Moreover, if a majority of market participants do it, their combined actions could destabilize the market. The aim of this project is to investigate so-called smart beta strategies to determine if they really can add value, or if they are merely marketing gimmicks used to sell dubious investment strategies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beta" title="beta">beta</a>, <a href="https://publications.waset.org/abstracts/search?q=alpha" title=" alpha"> alpha</a>, <a href="https://publications.waset.org/abstracts/search?q=active%20portfolio%20management" title=" active portfolio management"> active portfolio management</a>, <a href="https://publications.waset.org/abstracts/search?q=trading%20strategies" title=" trading strategies "> trading strategies </a> </p> <a href="https://publications.waset.org/abstracts/28119/smart-beta-portfolio-optimization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28119.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">355</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">1798</span> Optimization of Smart Beta Allocation by Momentum Exposure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20B.%20Frisch">J.

Indeed, these strategies allow a better control on portfolios risk factors and an optimized asset allocation by taking into account specific risks or wishes to generate alpha by outperforming indices called 'Beta'. Among many strategies independently used, this paper focuses on four of them: Minimum Variance Portfolio, Equal Risk Contribution Portfolio, Maximum Diversification Portfolio, and Equal-Weighted Portfolio. Their efficiency has been proven under constraints like momentum or market phenomenon, suggesting a reconsideration of cap-weighting.  To further increase strategy return efficiency, it is proposed here to compare their strengths and weaknesses inside time intervals corresponding to specific identifiable market phases, in order to define adapted strategies depending on pre-specified situations.  Results are presented as performance curves from different combinations compared to a benchmark. If a combination outperforms the applicable benchmark in well-defined actual market conditions, it will be preferred. It is mainly shown that such investment 'rules', based on both historical data and evolution of Smart Beta strategies, and implemented according to available specific market data, are providing very interesting optimal results with higher return performance and lower risk.  Such combinations have not been fully exploited yet and justify present approach aimed at identifying relevant elements characterizing them. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=smart%20beta" title="smart beta">smart beta</a>, <a href="https://publications.waset.org/abstracts/search?q=minimum%20variance%20portfolio" title=" minimum variance portfolio"> minimum variance portfolio</a>, <a href="https://publications.waset.org/abstracts/search?q=equal%20risk%20contribution%20portfolio" title=" equal risk contribution portfolio"> equal risk contribution portfolio</a>, <a href="https://publications.waset.org/abstracts/search?q=maximum%20diversification%20portfolio" title=" maximum diversification portfolio"> maximum diversification portfolio</a>, <a href="https://publications.waset.org/abstracts/search?q=equal%20weighted%20portfolio" title=" equal weighted portfolio"> equal weighted portfolio</a>, <a href="https://publications.waset.org/abstracts/search?q=combinations" title=" combinations"> combinations</a> </p> <a href="https://publications.waset.org/abstracts/9011/optimization-of-smart-beta-allocation-by-momentum-exposure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9011.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">340</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">1797</span> Wet Polymeric Precipitation Synthesis for Monophasic Tricalcium Phosphate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I.%20Grigoraviciute-Puroniene">I.

Sadasivan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Beta-lactam antibiotics are the most frequently prescribed medications in modern medicine. The antibiotic resistance by the production of enzyme beta-lactamase is an important mechanism seen in microorganisms. Resistance to beta-lactams mediated by beta-lactamases can be overcome successfully with the use of beta-lactamase inhibitors. New generations of the antibiotics contain mostly synthetic compounds, and many side effects have been reported for them. Combinations of beta-lactam and beta-lactamase inhibitors have become one of the most successful antimicrobial strategies in the current scenario of bacterial infections. Plant-based drugs are very cheap and having lesser adverse effect than synthetic compounds. The synergistic effect of eugenol acetate with beta-lactams restores the activity of beta-lactams, allowing their continued clinical use. It is reported here the enhanced inhibitory effect of phytochemical, eugenol acetate, isolated from the plant Syzygium aromaticum with beta-lactams on beta-lactamase. The compound was found to have synergistic effect with the antibiotic amoxicillin against antibiotic-resistant strain of S.aureus. The enzyme was purified from the organism and incubated with the compound. The assay showed that the compound could inhibit the enzymatic activity of beta-lactamase. Modeling and molecular docking studies indicated that the compound can fit into the active site of beta-lactamase and can mask the important residue for hydrolysis of beta-lactams. The synergistic effects of eugenol acetate with beta-lactam antibiotics may justify, the use of these plant compounds for the preparation of β-lactamase inhibitors against β-lactam resistant S.aureus. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=betalactamase" title="betalactamase">betalactamase</a>, <a href="https://publications.waset.org/abstracts/search?q=eugenol%20acetate" title=" eugenol acetate"> eugenol acetate</a>, <a href="https://publications.waset.org/abstracts/search?q=synergistic%20effect" title=" synergistic effect"> synergistic effect</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20modeling" title=" molecular modeling"> molecular modeling</a> </p> <a href="https://publications.waset.org/abstracts/59242/synergistic-effect-of-eugenol-acetate-with-betalactam-antibiotic-on-betalactamase-and-its-bioinformatics-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59242.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">249</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">1795</span> β-Lactamase Inhibitory Effects of Anchusa azurea Extracts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naoual%20Boussoualim">Naoual Boussoualim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hayat%20Trabsa"> Hayat Trabsa</a>, <a href="https://publications.waset.org/abstracts/search?q=Iman%20Krache"> Iman Krache</a>, <a href="https://publications.waset.org/abstracts/search?q=Lekhmici%20Arrar"> Lekhmici Arrar</a>, <a href="https://publications.waset.org/abstracts/search?q=Abderrahmane%20Baghiani"> Abderrahmane Baghiani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Resistance to antibiotics has emerged following their widespread use; the important mechanism of beta-lactam resistance in bacteria is the production of beta-lactamase. In order to find new bioactive beta-lactamase inhibitors, this study investigated the inhibition effect of the extracts of Anchusa azurea (AA) on a beta-lactamase from Bacillus cereus. The extracts exerted inhibitory effects on beta-lactamase in a dose-dependent manner, the results showed that the crude extract (BrE) and the ethyl acetate extract (AcE) of Anchusa azurea showed a very high inhibitory activity at a concentration of 10 mg, the percentage of inhibition was between 58% and 68%. Not all extracts were as potent as the original inhibitors such as clavulanic acid, the isolation and the structural elucidation of the active constituents in these extracts will provide useful means in the development of beta -lactamase inhibitors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anchusa%20azurea" title="Anchusa azurea">Anchusa azurea</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20product" title=" natural product"> natural product</a>, <a href="https://publications.waset.org/abstracts/search?q=resistance" title=" resistance"> resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=antibiotics" title=" antibiotics"> antibiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=beta-lactamase" title=" beta-lactamase"> beta-lactamase</a>, <a href="https://publications.waset.org/abstracts/search?q=inhibitors" title=" inhibitors"> inhibitors</a> </p> <a href="https://publications.waset.org/abstracts/41796/v-lactamase-inhibitory-effects-of-anchusa-azurea-extracts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41796.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">511</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">1794</span> A Case Study on Smart Energy City of the UK: Based on Business Model Innovation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Minzheong%20Song">Minzheong Song </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this paper is to see a case of smart energy evolution of the UK along with government projects and smart city project like 'Smart London Plan (SLP)' in 2013 with the logic of business model innovation (BMI). For this, it discusses the theoretical logic and formulates a research framework of evolving smart energy from silo to integrated system. The starting point is the silo system with no connection and in second stage, the private investment in smart meters, smart grids implementation, energy and water nexus, adaptive smart grid systems, and building marketplaces with platform leadership. As results, the UK’s smart energy sector has evolved from smart meter device installation through smart grid to new business models such as water-energy nexus and microgrid service within the smart energy city system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=smart%20city" title="smart city">smart city</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20energy" title=" smart energy"> smart energy</a>, <a href="https://publications.waset.org/abstracts/search?q=business%20model" title=" business model"> business model</a>, <a href="https://publications.waset.org/abstracts/search?q=business%20model%20innovation%20%28BMI%29" title=" business model innovation (BMI)"> business model innovation (BMI)</a> </p> <a href="https://publications.waset.org/abstracts/110461/a-case-study-on-smart-energy-city-of-the-uk-based-on-business-model-innovation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110461.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">161</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">1793</span> Design Manufacture and Testing of a Combined Alpha-Beta Double Piston Stirling Engine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Calvin%20Antony">A.

The paper focuses on alpha and beta type engines, capturing their benefits and eradicating their short comings; along with the output observed from the flywheel. In this model alpha engine is kinematically with a piston cylinder arrangement which works quite like a beta engine. The piston of the new cylinder is so designed that it replicates a glued displacer and power piston as similar to that of beta engine. The bigger part of the piston is the power piston, which has a gap around it, while the smaller part of the piston is tightly fit in the cylinder and acts like the displacer piston. We observed that the alpha-beta double piston stirling engine produces 25% increase in power compare to a conventional alpha stirling engine. This working model is a pointer towards for the design and development of an alpha-beta double piston Stirling engine for industrial applications for producing electricity from the heat producing exhaust gases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alpha-beta%20double%20piston%20stirling%20engine" title="alpha-beta double piston stirling engine ">alpha-beta double piston stirling engine </a>, <a href="https://publications.waset.org/abstracts/search?q=alpha%20stirling%20engine" title=" alpha stirling engine "> alpha stirling engine </a>, <a href="https://publications.waset.org/abstracts/search?q=beta%20double%20piston%20stirling%20engine" title=" beta double piston stirling engine "> beta double piston stirling engine </a>, <a href="https://publications.waset.org/abstracts/search?q=electricity%20from%20stirling%20engine" title=" electricity from stirling engine"> electricity from stirling engine</a> </p> <a href="https://publications.waset.org/abstracts/35104/design-manufacture-and-testing-of-a-combined-alpha-beta-double-piston-stirling-engine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35104.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">533</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">1792</span> A Security Study for Smart Metering Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Musaab%20Hasan">Musaab Hasan</a>, <a href="https://publications.waset.org/abstracts/search?q=Farkhund%20Iqbal"> Farkhund Iqbal</a>, <a href="https://publications.waset.org/abstracts/search?q=Patrick%20C.%20K.%20Hung"> Patrick C.

A smart grid is an essential part of any smart city as both consumers and power utility companies benefit from the features provided by the power grid. In addition to advanced features presented by smart grids, there may also be a risk when the grids are exposed to malicious acts such as security attacks performed by terrorists. Considering advanced security measures in the design of smart meters could reduce these risks. This paper presents a security study for smart metering systems with a prototype implementation of the user interfaces for future works. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=security%20design" title="security design">security design</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20city" title=" smart city"> smart city</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20meter" title=" smart meter"> smart meter</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20grid" title=" smart grid"> smart grid</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20metering%20system" title=" smart metering system"> smart metering system</a> </p> <a href="https://publications.waset.org/abstracts/79129/a-security-study-for-smart-metering-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79129.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">335</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">1791</span> Use of Beta Blockers in Patients with Reactive Airway Disease and Concomitant Hypertension or Ischemic Heart Disease </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bharti%20Chogtu%20Magazine">Bharti Chogtu Magazine</a>, <a href="https://publications.waset.org/abstracts/search?q=Dhanya%20Soodana%20Mohan"> Dhanya Soodana Mohan</a>, <a href="https://publications.waset.org/abstracts/search?q=Shruti%20Nair"> Shruti Nair</a>, <a href="https://publications.waset.org/abstracts/search?q=Tanwi%20Trushna"> Tanwi Trushna</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study was undertaken to analyse the cardiovascular drugs being prescribed in patients with concomitant reactive airway disease and hypertension or ischemic heart diseases (IHD).

The super-elasticity and low Young’s modulus are required in a wide range of applications in various industrial fields. For example, the metallic implant with low Young’s modulus and non-toxicity is desirable because the large difference of Young’s modulus between the human bone and the implant material may cause a stress-shielding phenomenon. We have investigated the role of Sn and Al in metastable beta Ti-Cr-Sn, Ti-Cr-Al, Ti-V-Sn, and Ti-V-Al alloys. The metastable beta Ti-Cr-Sn, Ti-Cr-Al, Ti-V-Sn, and Ti-V-Al alloys form during quenching from the beta field at high temperature. While Cr and V act as beta stabilizers, Sn and Al are considered as elements to suppress the athermal omega phase produced during quenching. The athermal omega phase degrades the properties of super-elasticity and Young’s modulus. Although Al and Sn as single elements are considered as an alpha stabilizer and neutral, respectively, Sn and Al acted also as beta stabilizers when added simultaneously with beta stabilized element of Cr or V in this experiment. The quenched microstructure of Ti-Cr-Sn, Ti-Cr-Al, Ti-V-Sn, and Ti-V-Al alloys shifts from martensitic structure to beta single-phase structure with increasing Cr or V. The Young’s modulus of Ti-Cr-Sn, Ti-Cr-Al, Ti-V-Sn, and Ti-V-Al alloys decreased and then increased with increasing Cr or V, each showing its own minimum value of Young's modulus respectively. The composition of the alloy with the minimum Young’s modulus is a near border composition where the quenched microstructure shifts from martensite to beta. The border composition of Ti-Cr-Sn and Ti-V-Sn alloys required only less amount of each beta stabilizer, Cr or V, than Ti-Cr-Al and Ti-V-Al alloys. This indicates that the effect of Sn as a beta stabilizer is stronger than Al. Sn and Al influenced the competitive relation between stress-induced martensitic transformation and slip deformation. Thus, super-elastic properties of metastable beta Ti-Cr-Sn, Ti-Cr-Al, Ti-V-Sn, and Ti-V-Al alloys varied depending on the alloyed element, Sn or Al. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=metastable%20beta%20Ti%20alloy" title="metastable beta Ti alloy">metastable beta Ti alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=super-elasticity" title=" super-elasticity"> super-elasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20Young%E2%80%99s%20modulus" title=" low Young’s modulus"> low Young’s modulus</a>, <a href="https://publications.waset.org/abstracts/search?q=stress-induced%20martensitic%20transformation" title=" stress-induced martensitic transformation"> stress-induced martensitic transformation</a>, <a href="https://publications.waset.org/abstracts/search?q=beta%20stabilized%20element" title=" beta stabilized element"> beta stabilized element</a> </p> <a href="https://publications.waset.org/abstracts/123727/effects-of-sn-and-al-on-phase-stability-and-mechanical-properties-of-metastable-beta-ti-alloys" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123727.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">1788</span> Molecular Dynamics Simulation of Beta-Glucosidase of Streptomyces</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adam%20Abate">Adam Abate</a>, <a href="https://publications.waset.org/abstracts/search?q=Elham%20Rasti"> Elham Rasti</a>, <a href="https://publications.waset.org/abstracts/search?q=Philip%20Romero"> Philip Romero </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Beta-glucosidase is the key enzyme component present in cellulase and completes the final step during cellulose hydrolysis by converting the cellobiose to glucose. The regulatory properties of beta-glucosidases are most commonly found for the retaining and inverting enzymes. Hydrolysis of a glycoside typically occurs with general acid and general base assistance from two amino acid side chains, normally glutamic or aspartic acids. In order to obtain more detailed information on the dynamic events origination from the interaction with enzyme active site, we carried out molecular dynamics simulations of beta-glycosidase in protonated state (Glu-H178) and deprotonated state (Glu178). The theoretical models generated from our molecular dynamics simulations complement and advance the structural information currently available, leading to a more detailed understanding of Beta-glycosidase structure and function.

Patients with Beta thalassemia whose anemia is not so severe as to necessitate transfusions are said to have thalassemia intermedia. Objective: The goal of this study is prenatal diagnosis for pregnancy woman with Beta thalassemia intermedia and her husband with Beta thalassemia carrier at high risk of Beta thalassemia major in Northern of Vietnam. Material and method: The family has a 6 years-old compound heterozygous thalassemia major for CD71/72(+A) and Hbb:c. -78A>G/nt-28(A>G) male child. The father was heterozygous for CD71/72(+A) mutation which is Beta plus type and the mother was compound heterozygosity of two different variants, namely, Hbb: c. -78A>G/nt-28(A>G) and CD26(A-G) HbE. Prenatal Beta thalassemia mutation detection in fetal DNA was carried out using multiplex Amplification-refractory mutation system ARMS-PCR and confirmed by direct Sanger-sequencing Hbb gene. Prenatal diagnoses were perfomed by amniotic fluid sampling from pregnant woman in the 16-18th week of pregnancy after the genotypes of parents of the probands were identified. Result: When amniotic fluid sample was analyzed for Beta globin gene (Hbb), we found that the genotype is heterozygous for CD71/72(+A) and CD26(A-G) HbE. This genotype is different from the 1st child of this family. Conclusion: Prenatal diagnosis helps the parents to know the genotype and the thalassemia status of the fetus, so they can have early decision on their pregnancy. Genetic diagnosis provided a useful method in diagnosis for familial members in pedigree, genetic counseling and prenatal diagnosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beta%20thalassemia%20intermedia" title="beta thalassemia intermedia">beta thalassemia intermedia</a>, <a href="https://publications.waset.org/abstracts/search?q=Hbb%20gene" title=" Hbb gene"> Hbb gene</a>, <a href="https://publications.waset.org/abstracts/search?q=pedigree" title=" pedigree"> pedigree</a>, <a href="https://publications.waset.org/abstracts/search?q=prenatal%20diagnosis" title=" prenatal diagnosis"> prenatal diagnosis</a> </p> <a href="https://publications.waset.org/abstracts/59114/prenatal-diagnosis-of-beta-thalassemia-intermedia-in-vietnamese-family-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59114.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">383</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1785</span> A Survey on the Blockchain Smart Contract System: Security Strengths and Weaknesses</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Malaw%20Ndiaye">Malaw Ndiaye</a>, <a href="https://publications.waset.org/abstracts/search?q=Karim%20Konate"> Karim Konate</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Smart contracts are computer protocols that facilitate, verify, and execute the negotiation or execution of a contract, or that render a contractual term unnecessary. Blockchain and smart contracts can be used to facilitate almost any financial transaction. Thanks to these smart contracts, the settlement of dividends and coupons could be automated. Smart contracts have become lucrative and profitable targets for attackers because they can hold a great amount of money. Smart contracts, although widely used in blockchain technology, are far from perfect due to security concerns. Since there are recent studies on smart contract security, none of them systematically study the strengths and weaknesses of smart contract security. Some have focused on an analysis of program-related vulnerabilities by providing a taxonomy of vulnerabilities. Other studies are responsible for listing the series of attacks linked to smart contracts. Although a series of attacks are listed, there is a lack of discussions and proposals on improving security. This survey takes stock of smart contract security from a more comprehensive perspective by correlating the level of vulnerability and systematic review of security levels in smart contracts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blockchain" title="blockchain">blockchain</a>, <a href="https://publications.waset.org/abstracts/search?q=Bitcoin" title=" Bitcoin"> Bitcoin</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20contract" title=" smart contract"> smart contract</a>, <a href="https://publications.waset.org/abstracts/search?q=criminal%20smart%20contract" title=" criminal smart contract"> criminal smart contract</a>, <a href="https://publications.waset.org/abstracts/search?q=security" title=" security"> security</a> </p> <a href="https://publications.waset.org/abstracts/135465/a-survey-on-the-blockchain-smart-contract-system-security-strengths-and-weaknesses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135465.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">168</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">1784</span> Investigating the Relationship between Growth, Beta and Liquidity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zahra%20Amirhosseini">Zahra Amirhosseini</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahtab%20Nameni"> Mahtab Nameni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to investigate the relationship between growth, beta, and Company's cash.

The security of this smart contract is critical to Ethereum’s operation and highly sensitive. In this paper, we present a formal model for smart contract, using the separated term-obligation (STO) strategy to formalize and verify the smart contract. We use the IBM smart sponsor contract (SSC) as an example to elaborate the detail of the formalizing process. We also propose a formal smart sponsor contract model (FSSCM) and verify SSC’s security properties with an interactive theorem prover Coq. We found the 'Unchecked-Send' vulnerability in the SSC, using our formal model and verification method. Finally, we demonstrate how we can formalize and verify other smart contracts with this approach, and our work indicates that this formal verification can effectively verify the correctness and security of smart contracts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=smart%20contract" title="smart contract">smart contract</a>, <a href="https://publications.waset.org/abstracts/search?q=formal%20verification" title=" formal verification"> formal verification</a>, <a href="https://publications.waset.org/abstracts/search?q=Ethereum" title=" Ethereum"> Ethereum</a>, <a href="https://publications.waset.org/abstracts/search?q=Coq" title=" Coq"> Coq</a> </p> <a href="https://publications.waset.org/abstracts/85595/formal-verification-for-ethereum-smart-contract-using-coq" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85595.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">691</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">1782</span> Prediction of All-Beta Protein Secondary Structure Using Garnier-Osguthorpe-Robson Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Tejasri">K.

Many varying formations of the chains are possible due to multiple combinations of amino acids and rotation in numerous positions along the chain. Protein structure prediction is one of the crucial goals worked towards by the members of bioinformatics and theoretical chemistry backgrounds. Among the four different structure levels in proteins, we emphasize mainly the secondary level structure. Generally, the secondary protein basically comprises alpha-helix and beta-sheets. Multi-class classification problem of data with disparity is truly a challenge to overcome and has to be addressed for the beta strands. Imbalanced data distribution constitutes a couple of the classes of data having very limited training samples collated with other classes. The secondary structure data is extracted from the protein primary sequence, and the beta-strands are predicted using suitable machine learning algorithms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=proteins" title="proteins">proteins</a>, <a href="https://publications.waset.org/abstracts/search?q=secondary%20structure%20elements" title=" secondary structure elements"> secondary structure elements</a>, <a href="https://publications.waset.org/abstracts/search?q=beta-sheets" title=" beta-sheets"> beta-sheets</a>, <a href="https://publications.waset.org/abstracts/search?q=beta-strands" title=" beta-strands"> beta-strands</a>, <a href="https://publications.waset.org/abstracts/search?q=alpha-helices" title=" alpha-helices"> alpha-helices</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning%20algorithms" title=" machine learning algorithms"> machine learning algorithms</a> </p> <a href="https://publications.waset.org/abstracts/158938/prediction-of-all-beta-protein-secondary-structure-using-garnier-osguthorpe-robson-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158938.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">94</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">1781</span> Citizen Participation in Smart Cities: Singapore and Tokyo</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Benson">Thomas Benson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Smart cities have been heralded as multi-faceted entities which utilise information and communication technologies to enhance citizen participation.

Primarily based on the ideology of the fourth industrial revolution a Smart City project should have Smart governance, smart health care, smart building, smart transportation, smart mobility, smart energy, smart technology and smart citizen. Considering the Indian scenario of current state of cities in India, it has become very essential to decide the specific parameters which would govern the development of a Smart City project. It has been observed that there are significant parameters beyond Information and Communication Technology (ICT), which govern the development of a Smart City project. This paper is an attempt to identify the Critical Success Factors (CSF) which are significantly responsible for the development of a Smart City project in Western India. Responses to questionnaire survey were analyzed on basis of Likert scale. They were further critically evaluated with help of Factor Comparison Method (FCM) and Analytical Hierarchy Process (AHP). The project authorities need to incorporate Building Information Modeling (BIM) to make the smart city project more collaborative. To make the project more sustainable, use of flyash in the concrete used, reduced usage of cement and steel, use of alternate fuels like biodiesel is recommended. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analytical%20hierarchical%20process" title="analytical hierarchical process">analytical hierarchical process</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20information%20modeling" title=" building information modeling"> building information modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20success%20factors" title=" critical success factors"> critical success factors</a>, <a href="https://publications.waset.org/abstracts/search?q=factor%20comparison%20method" title=" factor comparison method"> factor comparison method</a> </p> <a href="https://publications.waset.org/abstracts/73243/critical-success-factors-for-sustainable-smart-city-project-in-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73243.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">252</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">1779</span> Role of Pro-Inflammatory and Regulatory Cytokines in Pathogenesis of Graves’ Disease in Association with Autoantibody Thyroid and Regulatory FoxP3 T-Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dwitya%20Elvira">Dwitya Elvira</a>, <a href="https://publications.waset.org/abstracts/search?q=Eryati%20Darwin"> Eryati Darwin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Graves’ disease (GD) is an autoimmune thyroid disease. Imbalance of Th1/Th2 cells and T-regulatory (Treg)/Th17 cells was thought to play pivotal role in the pathogenesis of GD. Treg FoxP3 produced TGF-β to maintain regulatory function, and Th17 cells produced IL-17 as cytokines that were thought in mediating several autoimmune diseases. The aim of this study is to assess the role of IL-17 and TGF-β in the pathogenesis of GD and to investigate its correlation with Thyroid Stimulating Hormone Receptor Antibody (TRAb) and Treg FoxP3 expression. Method: 30 GD patients and 27 age and sex-matched controls were enrolled in this study. Diagnosis of GD was based on clinical and biochemical of GD. Serum IL-17, TGF-β, TRAb, and FoxP3 were measured by enzyme-linked immunosorbent assay (ELISA). Data were analyzed by using SPSS 21.0 (SPSS Inc.). Spearman rank correlation test was used for assessment of correlation. The statistical significance was accepted as P<0.05. Result: There was no significant correlation between IL-17 and TGF-β serum with expression of FoxP3 level in GD, but there was significant correlation between TGF-β and TRAb serum level (P<0.05). Serum levels of IL-17 and TGF-β were found to be elevated in patient group compared to control, where mean values of IL-17 were 14.43±2.15 pg/mL and TGF-β were 10.44±3.19 pg/mL in patients group; and in control group, level of IL-17 were 7.1±1.45 pg/mL and TGF-β were 4.95±1.35 pg/mL. Conclusion: Serum Il-17 and TGF-β were elevated in GD patients that reflect the role of inflammatory and regulatory cytokines activation in pathogenesis of GD. There was significant correlation between TGF-β and TRAb, revealing that Treg cytokines may play a role in pathogenesis of GD. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=IL-17" title="IL-17">IL-17</a>, <a href="https://publications.waset.org/abstracts/search?q=TGF-B" title=" TGF-B"> TGF-B</a>, <a href="https://publications.waset.org/abstracts/search?q=FoxP3" title=" FoxP3"> FoxP3</a>, <a href="https://publications.waset.org/abstracts/search?q=TRAb" title=" TRAb"> TRAb</a>, <a href="https://publications.waset.org/abstracts/search?q=Graves%E2%80%99%20disease" title=" Graves’ disease"> Graves’ disease</a> </p> <a href="https://publications.waset.org/abstracts/56187/role-of-pro-inflammatory-and-regulatory-cytokines-in-pathogenesis-of-graves-disease-in-association-with-autoantibody-thyroid-and-regulatory-foxp3-t-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56187.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">286</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">1778</span> Study on Beta-Ray Detection System in Water Using a MCNP Simulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ki%20Hyun%20Park">Ki Hyun Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Hye%20Min%20Park"> Hye Min Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeong%20Ho%20Kim"> Jeong Ho Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Chan%20Jong%20Park"> Chan Jong Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Koan%20Sik%20Joo"> Koan Sik Joo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the modern days, the use of radioactive substances is on the rise in the areas like chemical weaponry, industrial usage, and power plants. Although there are various technologies available to detect and monitor radioactive substances in the air, the technologies to detect underwater radioactive substances are scarce. In this study, computer simulation of the underwater detection system measuring beta-ray, a radioactive substance, has been done through MCNP. CaF₂, YAP(Ce) and YAG(Ce) have been used in the computer simulation to detect beta-ray as scintillator. Also, the source used in the computer simulation is Sr-90 and Y-90, both of them emitting only pure beta-ray. The distance between the source and the detector was shifted from 1mm to 10mm by 1 mm in the computer simulation. The result indicated that Sr-90 was impossible to measure below 1 mm since its emission energy is low while Y-90 was able to be measured up to 10mm underwater. In addition, the detector designed with CaF₂ had the highest efficiency among 3 scintillators used in the computer simulation. Since it was possible to verify the detectable range and the detection efficiency according to modeling through MCNP simulation, it is expected that such result will reduce the time and cost in building the actual beta-ray detector and evaluating its performances, thereby contributing the research and development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Beta-ray" title="Beta-ray">Beta-ray</a>, <a href="https://publications.waset.org/abstracts/search?q=CaF%E2%82%82" title=" CaF₂"> CaF₂</a>, <a href="https://publications.waset.org/abstracts/search?q=detector" title=" detector"> detector</a>, <a href="https://publications.waset.org/abstracts/search?q=MCNP%20simulation" title=" MCNP simulation"> MCNP simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=scintillator" title=" scintillator"> scintillator</a> </p> <a href="https://publications.waset.org/abstracts/53352/study-on-beta-ray-detection-system-in-water-using-a-mcnp-simulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53352.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">510</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">1777</span> Curcumin Promotes the Deoxygenated State of Hemoglobin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Roohallah%20Yousefi">Roohallah Yousefi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: In beta-thalassemia, an imbalance in the production of beta subunits of hemoglobin leads to the oxidation and deposition of excess alpha-globin chains at the cell membrane, resulting in the hemolysis of erythrocytes and a disorder of erythropoiesis. Antioxidants, such as curcumin, may promote this progression. This study aims to investigate the antioxidant effect of curcumin on hemolysate samples from patients with beta-thalassemia. Materials and methods: Pure curcumin was extracted and purified for use in studying its effect on the visual light absorbance of hemoglobin in hemolysate samples from beta-thalassemia patients compared to control samples. Changes in light absorbance at 540 and 700 nm wavelengths during exposure to curcumin were analyzed to examine the shift from oxyhemoglobin to deoxyhemoglobin. Results: Curcumin was found to dissolve rapidly and to a high degree in ethanol at 1 mg/ml, but did not dissolve in distilled water at the same concentration. The curcumin addition to the hemolysate sample of a patient with beta-thalassemia resulted in a decrease in the light absorbance of the sample at 540 nm wavelength, with minimal changes observed in the control sample. Conclusion: Curcumin deoxygenated the hemolysate samples from both the patient and control, causing hemoglobin precipitation to occur slowly. The study suggests a greater potential role for curcumin in deoxygenating hemoglobin in the hemolysate samples of beta-thalassemia patients compared to those of the normal control. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beta-thalassemia" title="beta-thalassemia">beta-thalassemia</a>, <a href="https://publications.waset.org/abstracts/search?q=hemoglobin" title=" hemoglobin"> hemoglobin</a>, <a href="https://publications.waset.org/abstracts/search?q=curcumin" title=" curcumin"> curcumin</a>, <a href="https://publications.waset.org/abstracts/search?q=alpha-globin" title=" alpha-globin"> alpha-globin</a> </p> <a href="https://publications.waset.org/abstracts/189204/curcumin-promotes-the-deoxygenated-state-of-hemoglobin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189204.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">29</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">1776</span> Beta Titanium Alloys: The Lowest Elastic Modulus for Biomedical Applications: A Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohsin%20Talib%20Mohammed">Mohsin Talib Mohammed</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahid%20A.%20Khan"> Zahid A.

Titanium (Ti) and its alloys are used extensively in biomedical applications based on their high specific strength and excellent corrosion resistance. Beta-Ti alloys containing completely biocompatible elements are exceptionally prospective materials for manufacturing of bioimplants. They have superior mechanical, chemical and electrochemical properties for use as biomaterials. These biomaterials have the ability to introduce the most important property of biochemical compatibility which is low elastic modulus. This review examines current information on the recent developments in alloying elements leading to improvements of beta Ti alloys for use as biomaterials. Moreover, this paper focuses mainly on the evolution, evaluation and development of the modulus of elasticity as an effective factor on the performance of beta alloys. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beta%20alloys" title="beta alloys">beta alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=biomedical%20applications" title=" biomedical applications"> biomedical applications</a>, <a href="https://publications.waset.org/abstracts/search?q=titanium%20alloys" title=" titanium alloys"> titanium alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=Young%27s%20modulus" title=" Young's modulus"> Young's modulus</a> </p> <a href="https://publications.waset.org/abstracts/6030/beta-titanium-alloys-the-lowest-elastic-modulus-for-biomedical-applications-a-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6030.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">325</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">1775</span> What Smart Can Learn about Art</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Faten%20Hatem">Faten Hatem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper explores the associated understanding of the role and meaning of art and whether it is perceived to be separate from smart city construction. The paper emphasises the significance of fulfilling the inherent need for discovery and interaction, driving people to explore new places and think of works of art. This is done by exploring the ways of thinking and types of art in Milton Keynes by illustrating a general pattern of misunderstanding that relies on the separation between smart, art, and architecture, promoting a better and deeper understanding of the interconnections between neuroscience, art, and architecture. A reflective approach is used to clarify the potential and impact of using art-based research, methodology, and ways of knowing when approaching global phenomena and knowledge production while examining the process of making and developing smart cities, in particular, asserting that factors can severely impact it in the process of conducting the study itself. It follows a case study as a research strategy.

Research indicates that cities have a role to play in combating urban challenges like crime, waste disposal, greenhouse gas emissions, and resource efficiency. These solutions should be such that they do not make city management less sustainable but should be solutions-driven, cost and resource-efficient, and smart. This study explores opportunities on how the City of Johannesburg, South Africa, can use Geographic Information Systems, Big Data and the Internet of Things (IoT) in identifying opportune areas to initiate smart city initiatives such as smart safety, smart utilities, smart mobility, and smart infrastructure in an integrated manner. The study will combine Big Data, using real-time data sources to identify hotspot areas that will benefit from ICT interventions. The GIS intervention will assist the city in avoiding a silo approach in its smart city development initiatives, an approach that has led to the failure of smart city development in other countries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=smart%20cities" title="smart cities">smart cities</a>, <a href="https://publications.waset.org/abstracts/search?q=internet%20of%20things" title=" internet of things"> internet of things</a>, <a href="https://publications.waset.org/abstracts/search?q=geographic%20information%20systems" title=" geographic information systems"> geographic information systems</a>, <a href="https://publications.waset.org/abstracts/search?q=johannesburg" title=" johannesburg"> johannesburg</a> </p> <a href="https://publications.waset.org/abstracts/159007/geospatial-information-for-smart-city-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159007.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">148</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">1773</span> Smart Product-Service System Innovation with User Experience: A Case Study of Chunmi</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ying%20Yu">Ying Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Wen-Chi%20Kuo"> Wen-Chi Kuo</a>, <a href="https://publications.waset.org/abstracts/search?q=Tung-Jung%20Sung"> Tung-Jung Sung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Product-Service System (PSS) has received widespread attention due to the increasing global competition in manufacturing and service markets. Today’s smart products and services are driven by Internet of things (IoT) technologies which will promote the transformation from traditional PSS to smart PSS. Although the smart PSS has some of technological achievements in businesses, it often ignores the real demands of target users when using products and services. Therefore, designers should know and learn the User Experience (UX) of smart products, services and systems. However, both of academia and industry still lack relevant development experience of smart PSS since it is an emerging field. In doing so, this is a case study of Xiaomi’s Chunmi, the largest IoT platform in the world, and addresses the two major issues: (1) why Chunmi should develop smart PSS strategies with UX; and (2) how Chunmi could successfully implement the strategic objectives of smart PSS through the design. The case study results indicated that: (1) the smart PSS can distinguish competitors by their unique UX which is difficult to duplicate; (2) early user engagement is crucial for the success of smart PSS; and (3) interaction, expectation, and enjoyment can be treated as a three-dimensional evaluation of UX design for smart PSS innovation. In conclusion, the smart PSS can gain competitive advantages through good UX design in the market. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=design" title="design">design</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20PSS" title=" smart PSS"> smart PSS</a>, <a href="https://publications.waset.org/abstracts/search?q=user%20experience" title=" user experience"> user experience</a>, <a href="https://publications.waset.org/abstracts/search?q=user%20engagement" title=" user engagement"> user engagement</a> </p> <a href="https://publications.waset.org/abstracts/120886/smart-product-service-system-innovation-with-user-experience-a-case-study-of-chunmi" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120886.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">136</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">1772</span> Smart Grids Cyber Security Issues and Challenges</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Imen%20Aouini">Imen Aouini</a>, <a href="https://publications.waset.org/abstracts/search?q=Lamia%20Ben%20Azzouz"> Lamia Ben Azzouz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The energy need is growing rapidly due to the population growth and the large new usage of power.

The Smart Grid is a complex architecture that covers critical devices and systems vulnerable to significant attacks. Hence, security is a crucial factor for the success and the wide deployment of Smart Grids. In this paper, we present security issues of the Smart Grid architecture and we highlight open issues that will make the Smart Grid security a challenging research area in the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=smart%20grids" title="smart grids">smart grids</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20meters" title=" smart meters"> smart meters</a>, <a href="https://publications.waset.org/abstracts/search?q=home%20area%20network" title=" home area network"> home area network</a>, <a href="https://publications.waset.org/abstracts/search?q=neighbor%20area%20network" title=" neighbor area network"> neighbor area network</a> </p> <a href="https://publications.waset.org/abstracts/35303/smart-grids-cyber-security-issues-and-challenges" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35303.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">424</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">1771</span> Effects of Ophiocordyceps dipterigena BCC 2073 β-Glucan as a Prebiotic on the in vitro Growth of Probiotic and Pathogenic Bacteria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wai%20Prathumpai">Wai Prathumpai</a>, <a href="https://publications.waset.org/abstracts/search?q=Pranee%20Rachtawee"> Pranee Rachtawee</a>, <a href="https://publications.waset.org/abstracts/search?q=Sutamat%20Khajeeram"> Sutamat Khajeeram</a>, <a href="https://publications.waset.org/abstracts/search?q=Pariya%20Na%20Nakorn"> Pariya Na Nakorn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The  β-glucan produced by <em>Ophiocordyceps dipterigena</em> BCC 2073 is a (1, 3)-β-D-glucan with highly branching O-6-linkedside chains that is resistant to acid hydrolysis (by hydrochloric acid and porcine pancreatic alpha-amylase). This β-glucan can be utilized as a prebiotic due to its advantageous structural and biological properties. The effects of using this β-glucan as the sole carbon source for the <em>in vitro</em> growth of two probiotic bacteria (<em>L. acidophilus</em> BCC 13938 and <em>B. animalis</em> ATCC 25527) were investigated. Compared with the effect of using 1% glucose or fructo-oligosaccharide (FOS) as the sole carbon source, using 1% β-glucan for this purpose showed that this prebiotic supported and stimulated the growth of both types of probiotic bacteria and induced them to produce the highest levels of metabolites during their growth. The highest levels of lactic and acetic acid, 10.04 g·L<sup>-1</sup> and 2.82 g·L<sup>-1</sup>, respectively, were observed at 2 h of cultivation using glucose as the sole carbon source. Furthermore, the fermentation broth obtained using 1% β-glucan as the sole carbon source had greater antibacterial activity against selected pathogenic bacteria (<em>B. subtilis </em>TISTR 008, <em>E. coli </em>TISTR 780, and <em>S. typhimurium</em> TISTR 292) than did the broths prepared using glucose or FOS as the sole carbon source. The fermentation broth obtained by growing <em>L. acidophilus</em> BCC 13938 in the presence of β-glucan inhibited the growth of <em>B. subtilis </em>TISTR 008 by more than 70% and inhibited the growth of both <em>S. typhimurium</em> TISTR 292 and <em>E. coli </em>TISTR 780 by more than 90%. In conclusion, <em>O. dipterigena</em> BCC 2073 is a potential source of a β-glucan prebiotic that could be used for commercial production in the near future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beta-glucan" title="beta-glucan">beta-glucan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ophiocordyceps%20dipterigena" title=" Ophiocordyceps dipterigena"> Ophiocordyceps dipterigena</a>, <a href="https://publications.waset.org/abstracts/search?q=prebiotic" title=" prebiotic"> prebiotic</a>, <a href="https://publications.waset.org/abstracts/search?q=probiotic" title=" probiotic"> probiotic</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial" title=" antimicrobial"> antimicrobial</a> </p> <a href="https://publications.waset.org/abstracts/93585/effects-of-ophiocordyceps-dipterigena-bcc-2073-v-glucan-as-a-prebiotic-on-the-in-vitro-growth-of-probiotic-and-pathogenic-bacteria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93585.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">151</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1770</span> Integrating Environmental and Ecological Justice for the Sustainable Development of Smart Cities: A Normative Eco Framework</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Benson">Thomas Benson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper leverages theoretical insights into two different justice approaches – environmental justice and ecological justice – to examine the effectiveness of sustainable development within smart cities and related smart city technology initiatives. Through theoretical development, the author seeks to establish an Eco Framework for smart cities and urban sustainable development. In turn, this paper aims to proffer the notion that there are ecologically sustainable ways in which smart cities can get smarter, and that such strategies can be compatible with ecological justice and environmental justice. Ultimately, a single conceptual framework is put forward to integrate the above approaches and concepts with normative prescriptions, which can serve researchers in the continued examination of smart cities and policymakers in their sustainable development of smart cities. <p class="card-text"><strong>Keywords:</strong> <a
