In the present paper a token-based group mutual exclusion algorithm, capable of handling transient faults, is proposed. The algorithm uses the concept of dynamic request sets. A time out mechanism is used to detect the token loss; also, a distributed scheme is used to regenerate the token. The worst case message complexity of the algorithm is n+1. The maximum concurrency and forum switch complexity of the algorithm are n and min (n, m) respectively, where n is the number of processes and m is the number of groups. The algorithm also satisfies another desirable property called smooth admission. The scheme can also be adapted to handle the extended group mutual exclusion problem. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Dynamic%20request%20sets" title="Dynamic request sets">Dynamic request sets</a>, <a href="https://publications.waset.org/search?q=Fault%20tolerance" title=" Fault tolerance"> Fault tolerance</a>, <a href="https://publications.waset.org/search?q=Smoothadmission" title=" Smoothadmission"> Smoothadmission</a>, <a href="https://publications.waset.org/search?q=Transient%20faults." title=" Transient faults."> Transient faults.</a> </p> <a href="https://publications.waset.org/2523/a-fault-tolerant-token-based-algorithm-for-group-mutual-exclusion-in-distributed-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/2523/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/2523/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/2523/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/2523/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/2523/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/2523/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/2523/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/2523/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/2523/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/2523/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/2523.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">1673</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">152</span> An Effective Traffic Control for both Real-time Bursts and Reliable Bursts in OBS Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Yuki%20Kondo">Yuki Kondo</a>, <a href="https://publications.waset.org/search?q=Takanori%20Nagano"> Takanori Nagano</a>, <a href="https://publications.waset.org/search?q=Yuki%20Takeda"> Yuki Takeda</a>, <a href="https://publications.waset.org/search?q=Young-Bok%20Choi"> Young-Bok Choi</a>, <a href="https://publications.waset.org/search?q=Hiromi%20Okada"> Hiromi Okada</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Optical burst switching(OBS) is considered as one of preferable network technologies for the next generation Internet. The Internet has two traffic classes, i.e. real-time bursts and reliable bursts. It is an important subject for OBS to achieve cooperated operation of real-time bursts and reliable bursts. In this paper, we proposes a new effective traffic control method named Separate TB+LB (Token Bucket + Leaky Bucket : TB+LB) method. The proposed method presents a new Token Bucket scheme for real-time bursts called as RBO-TB (Real-time Bursts Oriented Token Bucket). The method also applies the LB method to reliable bursts for obtaining better performance. This paper verifies the effectiveness of the Separate TB+LB method through the performance evaluation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=leaky%20bucket" title="leaky bucket">leaky bucket</a>, <a href="https://publications.waset.org/search?q=OBS" title=" OBS"> OBS</a>, <a href="https://publications.waset.org/search?q=traffic%20control" title=" traffic control"> traffic control</a>, <a href="https://publications.waset.org/search?q=token%20bucket." title=" token bucket."> token bucket.</a> </p> <a href="https://publications.waset.org/3219/an-effective-traffic-control-for-both-real-time-bursts-and-reliable-bursts-in-obs-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/3219/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/3219/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/3219/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/3219/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/3219/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/3219/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/3219/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/3219/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/3219/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/3219/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/3219.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">1496</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">151</span> On Bounding Jayanti's Distributed Mutual Exclusion Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Awadhesh%20Kumar%20Singh">Awadhesh Kumar Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>Jayanti-s algorithm is one of the best known abortable mutual exclusion algorithms.

There are many HLS algorithms and commercial tools. However, most of these algorithms consider a behavioral description for the system when a single token is presented to the system. This approach does not exploit extra hardware efficiently, especially in the design of digital filters where common operations may exist between successive tokens. In this paper, we modify the behavioral description to process multiple tokens in parallel. However, this approach is unlike the full processing that requires full hardware replication. It exploits the presence of common operations between successive tokens. The performance of the proposed approach is better than sequential processing and approaches that of full parallel processing as the hardware resources are increased. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Digital%20filters" title="Digital filters">Digital filters</a>, <a href="https://publications.waset.org/search?q=High%20level%20synthesis" title=" High level synthesis"> High level synthesis</a>, <a href="https://publications.waset.org/search?q=Sub-token%0Aforwarding" title=" Sub-token forwarding"> Sub-token forwarding</a> </p> <a href="https://publications.waset.org/14496/high-level-synthesis-of-digital-filters-based-on-sub-token-forwarding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/14496/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/14496/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/14496/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/14496/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/14496/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/14496/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/14496/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/14496/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/14496/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/14496/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/14496.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">1461</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">149</span> An Energy Efficient Algorithm for Distributed Mutual Exclusion in Mobile Ad-hoc Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Sayani%20Sil">Sayani Sil</a>, <a href="https://publications.waset.org/search?q=Sukanta%20Das"> Sukanta Das</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper reports a distributed mutual exclusion algorithm for mobile Ad-hoc networks.

To achieve this purpose, Dey et al. have already proposed an account management method for a federated login system using a blind signature scheme. In order to ensure account anonymity for the authentication provider, referred to as an IDP (identity provider), a blind signature scheme is utilized to generate an authentication token on an authentication service and the token is sent to an IDP. However, there is a problem with the proposed system. Malicious users can establish multiple accounts on an IDP by requesting such accounts. As a measure to solve this problem, in this paper, the authors propose an account checking method that is performed before account generation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=identity%20management" title="identity management">identity management</a>, <a href="https://publications.waset.org/search?q=blind%20signature" title=" blind signature"> blind signature</a>, <a href="https://publications.waset.org/search?q=privacy%20protection" title=" privacy protection"> privacy protection</a> </p> <a href="https://publications.waset.org/2657/account-management-method-with-blind-signature-scheme" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/2657/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/2657/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/2657/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/2657/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/2657/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/2657/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/2657/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/2657/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/2657/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/2657/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/2657.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">1544</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">145</span> Blockchain for Decentralized Finance: Impact, Challenges and Remediation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Rishabh%20Garg">Rishabh Garg</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>Blockchain technology can allow remote, untrusted parties in the banking and financial sector to reach consensus on the state of databases without the involvement of gatekeepers. Like a bookkeeper, it can manage all financial transactions including payments, settlements, fundraising, securities management, loans, credits and trade finance. It can outperform existing systems in terms of identity verification, asset transfers, peer-to-peer transfers, hedge funds, security and auditability. Blockchain-based decentralized finance (DeFi) is a new financial protocol. Being open and programmable, it enables various DeFi use-cases, including asset management, tokenization, tokenized derivatives, decentralized autonomous organizations, data analysis and valuation, payments, lending and borrowing, insurance, margin trading, prediction market, gambling and yield-farming, etc. In addition, it can ease financial transactions, cash-flow, use of programmable currency, no-loss lotteries, etc. This paper aims to assess the potential of decentralized finance by leveraging the blockchain-enabled Ethereum platform as an alternative to traditional finance. The study also aims to find out the impact of decentralized finance on prediction markets, quadratic funding and crowd-funding, together with the potential challenges and solutions associated with its implementation.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Advance%20trading" title="Advance trading">Advance trading</a>, <a href="https://publications.waset.org/search?q=crowd%20funding" title=" crowd funding"> crowd funding</a>, <a href="https://publications.waset.org/search?q=exchange%20tokens" title=" exchange tokens"> exchange tokens</a>, <a href="https://publications.waset.org/search?q=fund%20aggregation" title=" fund aggregation"> fund aggregation</a>, <a href="https://publications.waset.org/search?q=margin%20trading" title=" margin trading"> margin trading</a>, <a href="https://publications.waset.org/search?q=quadratic%20funding" title=" quadratic funding"> quadratic funding</a>, <a href="https://publications.waset.org/search?q=smart%20contracts" title=" smart contracts"> smart contracts</a>, <a href="https://publications.waset.org/search?q=streaming%20money" title=" streaming money"> streaming money</a>, <a href="https://publications.waset.org/search?q=token%20derivatives." title=" token derivatives."> token derivatives.</a> </p> <a href="https://publications.waset.org/10013000/blockchain-for-decentralized-finance-impact-challenges-and-remediation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10013000/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10013000/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10013000/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10013000/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10013000/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10013000/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10013000/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10013000/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10013000/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10013000/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10013000.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">343</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">144</span> A Distributed Group Mutual Exclusion Algorithm for Soft Real Time Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Abhishek%20Swaroop">Abhishek Swaroop</a>, <a href="https://publications.waset.org/search?q=Awadhesh%20Kumar%20Singh"> Awadhesh Kumar Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The group mutual exclusion (GME) problem is an interesting generalization of the mutual exclusion problem. Several solutions of the GME problem have been proposed for message passing distributed systems. However, none of these solutions is suitable for real time distributed systems. In this paper, we propose a token-based distributed algorithms for the GME problem in soft real time distributed systems. The algorithm uses the concepts of priority queue, dynamic request set and the process state. The algorithm uses first come first serve approach in selecting the next session type between the same priority levels and satisfies the concurrent occupancy property. The algorithm allows all n processors to be inside their CS provided they request for the same session. The performance analysis and correctness proof of the algorithm has also been included in the paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Concurrency" title="Concurrency">Concurrency</a>, <a href="https://publications.waset.org/search?q=Group%20mutual%20exclusion" title=" Group mutual exclusion"> Group mutual exclusion</a>, <a href="https://publications.waset.org/search?q=Priority" title=" Priority"> Priority</a>, <a href="https://publications.waset.org/search?q=Request%20set" title="Request set">Request set</a>, <a href="https://publications.waset.org/search?q=Token." title=" Token."> Token.</a> </p> <a href="https://publications.waset.org/6114/a-distributed-group-mutual-exclusion-algorithm-for-soft-real-time-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/6114/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/6114/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/6114/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/6114/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/6114/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/6114/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/6114/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/6114/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/6114/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/6114/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/6114.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">1713</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">143</span> Overview of Risk Management in Electricity Markets Using Financial Derivatives</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Aparna%20Viswanath">Aparna Viswanath</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>Electricity spot prices are highly volatile under optimal generation capacity scenarios due to factors such as nonstorability of electricity, peak demand at certain periods, generator outages, fuel uncertainty for renewable energy generators, huge investments and time needed for generation capacity expansion etc. As a result market participants are exposed to price and volume risk, which has led to the development of risk management practices.

As prevention, European Union and its member states have released new legal acts adjusting this area of law in recent years. There have been several cases in history of capital markets worldwide where it was shown that legislature may affect behavior of subjects on capital markets. In our paper we analyze main events on selected European stock exchanges in order to apply them on three chosen markets - Czech capital market represented by Prague Stock Exchange, German capital market represented by Deutsche Börse and Polish capital market represented by Warsaw Stock Exchange. We follow time series of development of the sum of listed derivatives on these three stock exchanges in order to evaluate popularity of those exchanges. Afterwards we compare newly listed derivatives in relation to the speed of development of these exchanges. We also make a comparison between trends in derivatives and shares development. We explain how a legal regulation may affect situation on capital markets. If the regulation is too strict, potential investors or traders are not willing to undertake it and move to other markets. On the other hand, if the regulation is too vague, trading scandals occur and the market is not reliable from the prospect of potential investors or issuers. We see that making the regulation stricter usually discourages subjects to stay on the market immediately although making the regulation vaguer to interest more subjects is usually much slower process.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Capital%20markets" title="Capital markets">Capital markets</a>, <a href="https://publications.waset.org/search?q=financial%20derivatives" title=" financial derivatives"> financial derivatives</a>, <a href="https://publications.waset.org/search?q=investors%27%20behavior" title=" investors' behavior"> investors' behavior</a>, <a href="https://publications.waset.org/search?q=regulation." title=" regulation."> regulation.</a> </p> <a href="https://publications.waset.org/10007753/impact-of-regulation-on-trading-in-financial-derivatives-in-europe" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10007753/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10007753/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10007753/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10007753/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10007753/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10007753/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10007753/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10007753/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10007753/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10007753/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10007753.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">918</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">140</span> Improved Triple Integral Inequalities of Hermite-Hadamard Type</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Leila%20Nasiri">Leila Nasiri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>In this paper, we present the concept of preinvex functions on the co-ordinates on an invex set and establish some triple integral inequalities of Hermite-Hadamard type for functions whose third order partial derivatives in absolute value are preinvex on the co-ordinates.

In the trial, 10 Karayaka sheep from 2 to 3 years of age were used. The animals were grazed in a pasture for ten months and fed with concentrate and vetch plus oat hay for the other two months (January and February) indoors. Highly significant linear and cubic relationships (P<0.001) were found among months for purine derivatives index, purine derivatives excretion, purine derivatives absorption, microbial-N and DOMI. Through urine sampling and the determination of levels of excreted urinary PD and Purine Derivatives / Creatinine ratio (PDC index), microbial-N values were estimated and they indicated that the protein nutrition of the sheep was insufficient.</p> <p>In conclusion, the prediction of protein nutrition of sheep under the field conditions may be possible with the use of spot urine sampling, urinary excreted PD and PDC index. The mean purine derivative levels in spot urine samples from sheep were highest in June, July and October. Protein nutrition of pastured sheep may be affected by weather changes, including rainfall. Spot urine sampling may useful in modeling the feed consumption of pasturing sheep. However, further studies are required under different field conditions with different breeds of sheep to develop spot urine sampling as a model.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Karayaka%20sheep" title="Karayaka sheep">Karayaka sheep</a>, <a href="https://publications.waset.org/search?q=spot%20sampling" title=" spot sampling"> spot sampling</a>, <a href="https://publications.waset.org/search?q=urinary%20purine%20derivatives" title=" urinary purine derivatives"> urinary purine derivatives</a>, <a href="https://publications.waset.org/search?q=PDC%20index" title=" PDC index"> PDC index</a>, <a href="https://publications.waset.org/search?q=microbial-N" title=" microbial-N"> microbial-N</a>, <a href="https://publications.waset.org/search?q=feed%20intake." title=" feed intake.

In recent years, blocking or reversing amyloid aggregation via the use of small compounds are considered as two useful approaches in hampering the development of these diseases. In this research, we have compared the ability of several manganese-salen derivatives, as synthetic compounds, and apigenin, as a natural flavonoid, to inhibit of hen egg-white lysozyme (HEWL) aggregation, as an in vitro model system. Different spectroscopic analyses such as Thioflavin T (ThT) and Anilinonaphthalene-8-sulfonic acid (ANS) fluorescence, Congo red (CR) absorbance along with transmission electron microscopy were used in this work to monitor the HEWL aggregation kinetic and inhibition. Our results demonstrated that both type of compounds were capable to prevent the formation of lysozyme amyloid aggregation in vitro. In addition, our data indicated that synthetic compounds had higher activity to inhibit of the β-sheet structures relative to natural compound. Regarding the higher antioxidant activities of the salen derivatives, it can be concluded that in addition to aromatic rings of each of the compounds, the potent antioxidant properties of salen derivatives contributes to lower lysozyme fibril accumulation.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Aggregation" title="Aggregation">Aggregation</a>, <a href="https://publications.waset.org/search?q=anti-amyloidogenic" title=" anti-amyloidogenic"> anti-amyloidogenic</a>, <a href="https://publications.waset.org/search?q=apigenin" title=" apigenin"> apigenin</a>, <a href="https://publications.waset.org/search?q=hen%20egg%0D%0Awhite%20lysozyme" title=" hen egg white lysozyme"> hen egg white lysozyme</a>, <a href="https://publications.waset.org/search?q=salen%20derivatives." title=" salen derivatives."> salen derivatives.</a> </p> <a href="https://publications.waset.org/9999257/comparative-studies-on-interactions-of-synthetic-and-natural-compounds-with-hen-egg-white-lysozyme" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/9999257/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/9999257/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/9999257/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/9999257/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/9999257/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/9999257/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/9999257/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/9999257/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/9999257/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/9999257/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/9999257.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">2082</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">136</span> Contextual SenSe Model: Word Sense Disambiguation Using Sense and Sense Value of Context Surrounding the Target</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Vishal%20Raj">Vishal Raj</a>, <a href="https://publications.waset.org/search?q=Noorhan%20Abbas"> Noorhan Abbas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>Ambiguity in NLP (Natural Language Processing) refers to the ability of a word, phrase, sentence, or text to have multiple meanings. This results in various kinds of ambiguities such as lexical, syntactic, semantic, anaphoric and referential. This study is focused mainly on solving the issue of Lexical ambiguity. Word Sense Disambiguation (WSD) is an NLP technique that aims to resolve lexical ambiguity by determining the correct meaning of a word within a given context. Most WSD solutions rely on words for training and testing, but we have used lemma and Part of Speech (POS) tokens of words for training and testing. Lemma adds generality and POS adds properties of word into token. We have designed a method to create an affinity matrix to calculate the affinity between any pair of lemma_POS (a token where lemma and POS of word are joined by underscore) of given training set. Additionally, we have devised an algorithm to create the sense clusters of tokens using affinity matrix under hierarchy of POS of lemma. Furthermore, three different mechanisms to predict the sense of target word using the affinity/similarity value are devised. Each contextual token contributes to the sense of target word with some value and whichever sense gets higher value becomes the sense of target word. So, contextual tokens play a key role in creating sense clusters and predicting the sense of target word, hence, the model is named Contextual SenSe Model (CSM). CSM exhibits a noteworthy simplicity and explication lucidity in contrast to contemporary deep learning models characterized by intricacy, time-intensive processes, and challenging explication. CSM is trained on SemCor training data and evaluated on SemEval test dataset. The results indicate that despite the naivety of the method, it achieves promising results when compared to the Most Frequent Sense (MFS) model. </p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Word%20Sense%20Disambiguation" title="Word Sense Disambiguation">Word Sense Disambiguation</a>, <a href="https://publications.waset.org/search?q=WSD" title=" WSD"> WSD</a>, <a href="https://publications.waset.org/search?q=Contextual%20SenSe%20Model" title=" Contextual SenSe Model"> Contextual SenSe Model</a>, <a href="https://publications.waset.org/search?q=Most%20Frequent%20Sense" title=" Most Frequent Sense"> Most Frequent Sense</a>, <a href="https://publications.waset.org/search?q=part%20of%20speech" title=" part of speech"> part of speech</a>, <a href="https://publications.waset.org/search?q=POS" title=" POS"> POS</a>, <a href="https://publications.waset.org/search?q=Natural%20Language%20Processing" title=" Natural Language Processing"> Natural Language Processing</a>, <a href="https://publications.waset.org/search?q=NLP" title=" NLP"> NLP</a>, <a href="https://publications.waset.org/search?q=OOV" title=" OOV"> OOV</a>, <a href="https://publications.waset.org/search?q=out%20of%20vocabulary" title=" out of vocabulary"> out of vocabulary</a>, <a href="https://publications.waset.org/search?q=ELMo" title=" ELMo"> ELMo</a>, <a href="https://publications.waset.org/search?q=Embeddings%20from%20Language%20Model" title=" Embeddings from Language Model"> Embeddings from Language Model</a>, <a href="https://publications.waset.org/search?q=BERT" title=" BERT"> BERT</a>, <a href="https://publications.waset.org/search?q=Bidirectional%20Encoder%20Representations%20from%20Transformers" title=" Bidirectional Encoder Representations from Transformers"> Bidirectional Encoder Representations from Transformers</a>, <a href="https://publications.waset.org/search?q=Word2Vec" title=" Word2Vec"> Word2Vec</a>, <a href="https://publications.waset.org/search?q=lemma_POS" title=" lemma_POS"> lemma_POS</a>, <a href="https://publications.waset.org/search?q=Algorithm." title=" Algorithm."> Algorithm.</a> </p> <a href="https://publications.waset.org/10013458/contextual-sense-model-word-sense-disambiguation-using-sense-and-sense-value-of-context-surrounding-the-target" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10013458/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10013458/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10013458/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10013458/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10013458/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10013458/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10013458/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10013458/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10013458/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10013458/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10013458.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">387</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">135</span> Improved Approximation to the Derivative of a Digital Signal Using Wavelet Transforms for Crosstalk Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=S.%20P.%20Kozaitis">S.

Unfortunately, derivatives tend to be very sensitive to even low levels of noise. In this work we approximated the derivatives of both quiet and noisy digital signals using a wavelet-based technique. The results are presented for Gaussian digital edges, IBIS Model digital edges, and digital edges in oscilloscope data captured from an actual printed circuit board. Tradeoffs between accuracy and noise immunity are presented. The results show that the wavelet technique can produce first derivative approximations that are accurate to within 5% or better, even under noisy conditions. The wavelet technique can be used to calculate the derivative of a digital signal edge when conventional methods fail. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=digital%20signals" title="digital signals">digital signals</a>, <a href="https://publications.waset.org/search?q=electronics" title=" electronics"> electronics</a>, <a href="https://publications.waset.org/search?q=IBIS%20model" title=" IBIS model"> IBIS model</a>, <a href="https://publications.waset.org/search?q=printedcircuit%20board" title=" printedcircuit board"> printedcircuit board</a>, <a href="https://publications.waset.org/search?q=wavelets" title=" wavelets"> wavelets</a> </p> <a href="https://publications.waset.org/7940/improved-approximation-to-the-derivative-of-a-digital-signal-using-wavelet-transforms-for-crosstalk-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/7940/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/7940/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/7940/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/7940/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/7940/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/7940/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/7940/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/7940/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/7940/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/7940/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/7940.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">1877</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">134</span> On Discretization of Second-order Derivatives in Smoothed Particle Hydrodynamics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=R.%20Fatehi">R.

In this paper, various methods used for discretization of second-order spatial derivatives are investigated in the context of Smoothed Particle Hydrodynamics. Three popular forms (i.e. "double summation", "second-order kernel derivation", and "difference scheme") are studied using one-dimensional unsteady heat conduction equation. To assess these schemes, transient response to a step function initial condition is considered. Due to parabolic nature of the heat equation, one can expect smooth and monotone solutions. It is shown, however in this paper, that regardless of the type of kernel function used and the size of smoothing radius, the double summation discretization form leads to non-physical oscillations which persist in the solution. Also, results show that when a second-order kernel derivative is used, a high-order kernel function shall be employed in such a way that the distance of inflection point from origin in the kernel function be less than the nearest particle distance. Otherwise, solutions may exhibit oscillations near discontinuities unlike the "difference scheme" which unconditionally produces monotone results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Heat%20conduction" title="Heat conduction">Heat conduction</a>, <a href="https://publications.waset.org/search?q=Meshfree%20methods" title=" Meshfree methods"> Meshfree methods</a>, <a href="https://publications.waset.org/search?q=Smoothed%20ParticleHydrodynamics%20%28SPH%29" title=" Smoothed ParticleHydrodynamics (SPH)"> Smoothed ParticleHydrodynamics (SPH)</a>, <a href="https://publications.waset.org/search?q=Second-order%20derivatives." title=" Second-order derivatives."> Second-order derivatives.</a> </p> <a href="https://publications.waset.org/14882/on-discretization-of-second-order-derivatives-in-smoothed-particle-hydrodynamics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/14882/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/14882/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/14882/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/14882/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/14882/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/14882/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/14882/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/14882/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/14882/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/14882/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/14882.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">3088</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">133</span> Efficient Preparation and Characterization of Carbohydrate Based Monomers.

The method uses a fifth order spline interpolation, with up to C3 continuity at specific points to compute the shape of the deformed geometry. First and second order derivatives over a surface are the resulting parameters of a given heating line on a plate. These parameters are determined through experiments and/or finite element simulations. Very accurate kriging models are fitted to real or virtual surfaces to build-up a database of maps. Maps of first and second order derivatives are then applied on numerical plate models to evaluate their evolving shapes through a sequence of heating lines. Adding an optimization process to this approach would allow determining the trajectories of heating lines needed to shape complex geometries, such as Francis turbine blades. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Deformation" title="Deformation">Deformation</a>, <a href="https://publications.waset.org/search?q=kriging" title=" kriging"> kriging</a>, <a href="https://publications.waset.org/search?q=fifth%20order%20spline%0D%0Ainterpolation" title=" fifth order spline interpolation"> fifth order spline interpolation</a>, <a href="https://publications.waset.org/search?q=first" title=" first"> first</a>, <a href="https://publications.waset.org/search?q=second%20and%20third%20order%20derivatives" title=" second and third order derivatives"> second and third order derivatives</a>, <a href="https://publications.waset.org/search?q=C3%20continuity" title=" C3 continuity"> C3 continuity</a>, <a href="https://publications.waset.org/search?q=line%20heating" title=" line heating"> line heating</a>, <a href="https://publications.waset.org/search?q=plate%20forming" title=" plate forming"> plate forming</a>, <a href="https://publications.waset.org/search?q=thermal%20forming." title=" thermal forming."> thermal forming.</a> </p> <a href="https://publications.waset.org/10002296/line-heating-forming-methodology-and-application-using-kriging-and-fifth-order-spline-formulations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10002296/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10002296/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10002296/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10002296/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10002296/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10002296/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10002296/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10002296/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10002296/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10002296/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10002296.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">2158</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">130</span> Fatty Acids Derivatives and Steroidal Saponins: Abundance in the Resistant Date Palm to Fusarium oxysporum f. sp. albedinis, Causal Agent of Bayoud Disease</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=R.%20Gaceb-Terrak">R.

In the aim to understand more about the defense mechanisms implied, we realized phytochemical analyses of this cultivar leaflets and roots and this, for the first time, using gas chromatography-mass spectrometry (GC-MS).The examination of our results shows that fifty-four molecules have been detected, fourteen of which are common to leaflets and roots. This study revealed also the organs' richness in derivatives fatty acids: both saturated and unsaturated are represented mainly by methyl esters of Hexadecanoic and 9,12,15-Octadecatrienoic acids. 1-Dodecanethiol, derivative Dodecanoic acid is only present in roots. It’s of great interest to note that the screening revealed the steroidal saponins abundance, among which Yamogenin acetate and Diosgenin, exclusively detected in Takerbucht.

In particular, the frequency and profit of arbitrage are measured in the following three arbitrage tests: (1) SET50 futures vs. ThaiDEX SET50 ETF, (2) SET50 futures vs. SET50 component stocks, and (3) ThaiDEX SET50 ETF vs. SET50 component stocks are investigated. For tests (2) and (3), the problems involve conic optimization and quadratic programming as subproblems. This research is first to apply conic optimization and quadratic programming techniques in the context of index arbitrage and is first to investigate such index arbitrage in the Thai equity and derivatives markets. Thus, the contribution of this study is twofold. First, its results would help understand the contribution of the derivatives securities to the efficiency of the Thai markets. Second, the methodology employed in this study can be applied to other geographical markets, with minor adjustments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Conic%20optimization" title="Conic optimization">Conic optimization</a>, <a href="https://publications.waset.org/search?q=Equity%20index%20arbitrage" title=" Equity index arbitrage"> Equity index arbitrage</a>, <a href="https://publications.waset.org/search?q=Executionlags" title=" Executionlags"> Executionlags</a>, <a href="https://publications.waset.org/search?q=Quadratic%20programming" title=" Quadratic programming"> Quadratic programming</a>, <a href="https://publications.waset.org/search?q=SET50%20index%20futures" title=" SET50 index futures"> SET50 index futures</a>, <a href="https://publications.waset.org/search?q=ThaiDEX%20SET50ETF" title=" ThaiDEX SET50ETF"> ThaiDEX SET50ETF</a>, <a href="https://publications.waset.org/search?q=Transaction%20costs" title=" Transaction costs"> Transaction costs</a> </p> <a href="https://publications.waset.org/10717/applications-of-conic-optimization-and-quadratic-programming-in-the-investigation-of-index-arbitrage-in-the-thai-derivatives-and-equity-markets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10717/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10717/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10717/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10717/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10717/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10717/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10717/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10717/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10717/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10717/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10717.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">1574</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">127</span> Features of the Immune Response in Mice were Immunized with Polio Vaccine in Combination with Chitosan Preparations as Adjuvants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Nelly%20%D0%9A.%20Akhmatova">Nelly 袣.

The <em>N</em>-protected indoles have been prepared under moderate and scalable electrolytic conditions. The conduct of the reactions was performed in a simple divided cell under constant current without oxidizing reagents or transition-metal catalysts. The synthesized products have been characterized via UV/Vis spectrophotometry, 1H-NMR, and FTIR spectroscopy. A possible reaction mechanism is discussed based on the <em>N</em>-protective products.
