The impact of various guard ring design (geometrical) parameters is examined. Furthermore, the increase of isolation (resulting in reduction of the noise coupling) between the pads by cutting the ring, or by using multiple rings, is also analyzed.

Similarly there is vast amount of research on the nonassociative structures of semigroups i.e. groupoids and that of rings i.e. nonassociative rings. However it is unfortunate that we do not have a parallel notions or study of non-associative near-rings. In this work we shall attempt to generalize a few known results and study the commutativity of Jordan ideal in 3-prime near-rings satisfying certain identities involving the Jordan ideal. We study the derivations satisfying certain differential identities on Jordan ideals of 3-prime near-rings. Moreover, we provide examples to show that hypothesis of our results are necessary. We give some new results and examples concerning the existence of Jordan ideal and derivations in near-rings. These near-rings can be used to build a new codes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3-prime%20near-rings" title="3-prime near-rings">3-prime near-rings</a>, <a href="https://publications.waset.org/abstracts/search?q=near-rings" title=" near-rings"> near-rings</a>, <a href="https://publications.waset.org/abstracts/search?q=Jordan%20ideal" title=" Jordan ideal"> Jordan ideal</a>, <a href="https://publications.waset.org/abstracts/search?q=derivations" title=" derivations"> derivations</a> </p> <a href="https://publications.waset.org/abstracts/52456/some-properties-in-jordan-ideal-on-3-prime-near-rings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52456.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">314</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">223</span> Jacobson Semisimple Skew Inverse Laurent Series Rings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Moussavi">Ahmad Moussavi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we are concerned with the Jacobson semisimple skew inverse Laurent series rings R((x−1; α, δ)) and the skew Laurent power series rings R[[x, x−1; α]], where R is an associative ring equipped with an automorphism α and an α-derivation δ.

Since the introduction of this concept, the application of soft sets has been restricted to associative algebraic structures (groups, semi groups, associative rings, semi-rings etc.). Acceptably, though the study of soft sets, where the base set of parameters is a commutative structure, has attracted the attention of many researchers for more than one decade. But on the other hand there are many sets which are naturally endowed by two compatible binary operations forming a non-associative ring and we may dig out examples which investigate a non-associative structure in the context of soft sets. Thus it seems natural to apply the concept of soft sets to non-commutative and non-associative structures. In present paper, we make a new approach to apply Molodtsoves notion of soft sets to LA-ring (a class of non-associative ring). We extend the study of soft commutative rings from theoretical aspect. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soft%20sets" title="soft sets">soft sets</a>, <a href="https://publications.waset.org/abstracts/search?q=LA-rings" title=" LA-rings"> LA-rings</a>, <a href="https://publications.waset.org/abstracts/search?q=soft%20LA-rings" title=" soft LA-rings"> soft LA-rings</a>, <a href="https://publications.waset.org/abstracts/search?q=soft%20ideals" title=" soft ideals"> soft ideals</a>, <a href="https://publications.waset.org/abstracts/search?q=soft%20prime%20ideals" title=" soft prime ideals"> soft prime ideals</a>, <a href="https://publications.waset.org/abstracts/search?q=idealistic%0D%0Asoft%20LA-rings" title=" idealistic soft LA-rings"> idealistic soft LA-rings</a>, <a href="https://publications.waset.org/abstracts/search?q=LA-ring%20homomorphism" title=" LA-ring homomorphism "> LA-ring homomorphism </a> </p> <a href="https://publications.waset.org/abstracts/33475/application-of-soft-sets-to-non-associative-rings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33475.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">469</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">218</span> Solution for Rider Ring Wear Problem in Boil off Gas Reciprocating Compressor: A Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hessam%20Mortezaei">Hessam Mortezaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Saeid%20Joudakian"> Saeid Joudakian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the wear problem on rider rings of boil off gas compressor has been studied.

The characterization of modules over Dedekind prime rings that will be investigated is an adoption of Noetherian and hereditary concept. Dedekind prime rings are Noetherian and hereditary rings. This property of Dedekind prime rings is a background of the idea of adopting arises. In Noetherian area, it was known that a ring R is Noetherian ring if and only if every finitely generated R-module is a Noetherian module. Similar to that result, a characterization of the hereditary ring is related to its projective modules. That is, a ring R is hereditary ring if and only if every projective R-module is a hereditary module. Due to the above two results, we suppose that characterization of a Dedekind prime ring can be analyzed from finitely generated modules over it. We propose a conjecture: a ring R is a Dedekind prime ring if and only if every finitely generated uniform R-module is a Dedekind module. In this article, we will generalize a concept of the Dedekind module for non-commutative ring case and present a part of the above conjecture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dedekind%20domains" title="dedekind domains">dedekind domains</a>, <a href="https://publications.waset.org/abstracts/search?q=dedekind%20prime%20rings" title=" dedekind prime rings"> dedekind prime rings</a>, <a href="https://publications.waset.org/abstracts/search?q=dedekind%20modules" title=" dedekind modules"> dedekind modules</a>, <a href="https://publications.waset.org/abstracts/search?q=uniform%20modules" title=" uniform modules"> uniform modules</a> </p> <a href="https://publications.waset.org/abstracts/32475/on-modules-over-dedekind-prime-rings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32475.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">446</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">216</span> Evaluation of Hydrocarbons in Tissues of Bivalve Mollusks from the Red Sea Coast</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asma%20Ahmed%20Aljohani">Asma Ahmed Aljohani</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Orif"> Mohammed Orif</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The concentration of polycyclic aromatic hydrocarbons (PAH) in clam (A. glabrata) was examined in samples collected from Alseef Beach, 30 km south of Jeddah city.

Diagnostic ratios for PAH source distinction suggested pyrogenic or anthropogenic sources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bivalves" title="bivalves">bivalves</a>, <a href="https://publications.waset.org/abstracts/search?q=biomonitoring" title=" biomonitoring"> biomonitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrocarbons" title=" hydrocarbons"> hydrocarbons</a>, <a href="https://publications.waset.org/abstracts/search?q=PAHs" title=" PAHs"> PAHs</a> </p> <a href="https://publications.waset.org/abstracts/159285/evaluation-of-hydrocarbons-in-tissues-of-bivalve-mollusks-from-the-red-sea-coast" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159285.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">103</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">215</span> Analysis of the Institutional Performance of the National Human Rights Commission (CNDH) Regarding Recommendations Issued to the National Guard (GN) in Migration Control Tasks in Mexico</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luis%20Hector%20Benitez%20Ayala">Luis Hector Benitez Ayala</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims to analyze the institutional performance of the National Guard and the National Human Rights Commission (CNDH) based on the recommendations issued by the CNDH following the documentation of human rights violations against irregular migrants. The methodological foundation relies on cases with comparable characteristics related to irregular migration status originating from various Latin American countries. The temporal and spatial framework focuses on recommendations issued since 2019, the year marking the establishment of the National Guard across Mexican territory. This study examines Mexican migration flows using a qualitative methodology that facilitates a review of migration operations through documentation. It draws from data provided by the Unit for Migration Policy, Registration, and Identity of Persons (UPMRIP), activity reports from the National Human Rights Commission and also considers the normative and organizational frameworks. By reviewing the general organizational manuals of the National Guard and the CNDH, the analysis highlights the organizational structure and responsibilities inherent to both institutions. Additionally, it evaluates, at an international level, the recommendations from the nation-states that participated in the Universal Periodic Review (UPR) of 2024. The concluding section outlines the compliance status of the National Guard regarding the recommendations issued by the CNDH. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=national%20guard" title="national guard">national guard</a>, <a href="https://publications.waset.org/abstracts/search?q=national%20human%20rights%20commission" title=" national human rights commission"> national human rights commission</a>, <a href="https://publications.waset.org/abstracts/search?q=Mexico" title=" Mexico"> Mexico</a>, <a href="https://publications.waset.org/abstracts/search?q=migration" title=" migration"> migration</a> </p> <a href="https://publications.waset.org/abstracts/198785/analysis-of-the-institutional-performance-of-the-national-human-rights-commission-cndh-regarding-recommendations-issued-to-the-national-guard-gn-in-migration-control-tasks-in-mexico" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/198785.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">2</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">214</span> Interaction between Unsteady Supersonic Jet and Vortex Rings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kazumasa%20Kitazono">Kazumasa Kitazono</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiroshi%20Fukuoka"> Hiroshi Fukuoka</a>, <a href="https://publications.waset.org/abstracts/search?q=Nao%20Kuniyoshi"> Nao Kuniyoshi</a>, <a href="https://publications.waset.org/abstracts/search?q=Minoru%20Yaga"> Minoru Yaga</a>, <a href="https://publications.waset.org/abstracts/search?q=Eri%20Ueno"> Eri Ueno</a>, <a href="https://publications.waset.org/abstracts/search?q=Naoaki%20Fukuda"> Naoaki Fukuda</a>, <a href="https://publications.waset.org/abstracts/search?q=Toshio%20Takiya"> Toshio Takiya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The unsteady supersonic jet formed by a shock tube with a small high-pressure chamber was used as a simple alternative model for pulsed laser ablation. Understanding the vortex ring formed by the shock wave is crucial in clarifying the behavior of unsteady supersonic jet discharged from an elliptical cell. Therefore, this study investigated the behavior of vortex rings and a jet. The experiment and numerical calculation were conducted using the schlieren method and by solving the axisymmetric two-dimensional compressible Navier–Stokes equations, respectively. In both, the calculation and the experiment, laser ablation is conducted for a certain duration, followed by discharge through the exit. Moreover, a parametric study was performed to demonstrate the effect of pressure ratio on the interaction among vortex rings and the supersonic jet. The interaction between the supersonic jet and the vortex rings increased the velocity of the supersonic jet up to the magnitude of the velocity at the center of the vortex rings. The interaction between the vortex rings increased the velocity at the center of the vortex ring. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamics" title="computational fluid dynamics">computational fluid dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=shock-wave" title=" shock-wave"> shock-wave</a>, <a href="https://publications.waset.org/abstracts/search?q=unsteady%20jet" title=" unsteady jet"> unsteady jet</a>, <a href="https://publications.waset.org/abstracts/search?q=vortex%20ring" title=" vortex ring"> vortex ring</a> </p> <a href="https://publications.waset.org/abstracts/50911/interaction-between-unsteady-supersonic-jet-and-vortex-rings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50911.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">476</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">213</span> A Generalization of the Secret Sharing Scheme Codes Over Certain Ring</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20%C3%96zbek">Ibrahim Özbek</a>, <a href="https://publications.waset.org/abstracts/search?q=Erdo%C4%9Fan%20Mehmet%20%C3%96zkan"> Erdoğan Mehmet Özkan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, we generalize (k,n) threshold secret sharing scheme on the study Ozbek and Siap to the codes over the ring Fq+ αFq.

It also concerns with the study of abstractions such as groups, rings, and fields. Due to the development of these abstractions, it is extended to consider other structures, such as vectors, matrices, and polynomials, which are non-numerical objects. Computer algebra is the implementation of algebraic methods as algorithms and computer programs. Recently, many algebraic cryptosystem protocols are based on non-commutative algebraic structures, such as authentication, key exchange, and encryption-decryption processes are adopted. Cryptography is the science that aimed at sending the information through public channels in such a way that only an authorized recipient can read it. Ring theory is the most attractive category of algebra in the area of cryptography. In this paper, we employ the algebraic structure called skew -Armendariz rings to design a neoteric algorithm for zero knowledge proof. The proposed protocol is established and illustrated through numerical example, and its soundness and completeness are proved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cryptosystem" title="cryptosystem">cryptosystem</a>, <a href="https://publications.waset.org/abstracts/search?q=identification" title=" identification"> identification</a>, <a href="https://publications.waset.org/abstracts/search?q=skew%20%CF%80-Armendariz%20rings" title=" skew π-Armendariz rings"> skew π-Armendariz rings</a>, <a href="https://publications.waset.org/abstracts/search?q=skew%20polynomial%20rings" title=" skew polynomial rings"> skew polynomial rings</a>, <a href="https://publications.waset.org/abstracts/search?q=zero%20knowledge%20protocol" title=" zero knowledge protocol"> zero knowledge protocol</a> </p> <a href="https://publications.waset.org/abstracts/75349/generalized-p-armendariz-authentication-cryptosystem" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75349.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">224</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">211</span> Linkage between Trace Element Distribution and Growth Ring Formation in Japanese Red Coral (Paracorallium japonicum)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luan%20Trong%20Nguyen">Luan Trong Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Azizur%20Rahman"> M.

The Mg, P and S distribution in µ-XRF mapping images correspond to the dark and light bands along the annual growth rings observed in microscopic images of the coral skeleton. The µ-XRF mapping data showed a positive correlation (r = 0.6) between P and S distribution in the coral skeleton. A contrasting distribution pattern of S and Mg along the axial skeleton of P. japonicum indicates a weak negative correlation (r = -0.2) between these two trace elements. The distribution pattern of S, P and Mg reveals linkage between their distributions and the formation of dark/light bands along the annual growth rings in the axial skeleton of P. japonicum. Sulfur and P were distributed in the organic matrix rich dark bands, while Mg was distributed in the light bands of the annual growth rings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C2%B5-XRF" title="µ-XRF">µ-XRF</a>, <a href="https://publications.waset.org/abstracts/search?q=trace%20element" title=" trace element"> trace element</a>, <a href="https://publications.waset.org/abstracts/search?q=precious%20coral" title=" precious coral"> precious coral</a>, <a href="https://publications.waset.org/abstracts/search?q=Paracorallium%20japonicum" title=" Paracorallium japonicum"> Paracorallium japonicum</a> </p> <a href="https://publications.waset.org/abstracts/4207/linkage-between-trace-element-distribution-and-growth-ring-formation-in-japanese-red-coral-paracorallium-japonicum" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4207.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">447</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">210</span> Tribological Behavior of PTFE Composites Used for Guide Rings of Hydraulic Actuating Cylinders under Oil-Lubricated Condition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Trabelsi%20Mohamed">Trabelsi Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Kharrat%20Mohamed"> Kharrat Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Dammak%20Maher"> Dammak Maher</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Guide rings play an important role in the performance and durability of hydraulic actuating cylinders. In service, guide rings surfaces are subjected to friction and wear against steel counterface. A good mastery of these phenomena is required for the improvement of the energy safeguard and the durability of the actuating cylinder. Polytetrafluoroethylene (PTFE) polymer is extensively used in guide rings thanks to its low coefficient of friction, its good resistance to solvents as well as its high temperature stability. In this study, friction and wear behavior of two PTFE composites filled with bronze and bronze plus MoS2 were evaluated under oil-lubricated condition, aiming as guide rings for hydraulic actuating cylinder. Wear tests of the PTFE composite specimen sliding against steel ball were conducted using reciprocating linear tribometer. The wear mechanisms of the composites under the same sliding condition were discussed, based on Scanning Electron Microscopy examination of the worn composite surface and the optical micrographs of the steel counter surface. As for the results, comparative friction behaviors of the PTFE composites and lower friction coefficients were recorded under oil lubricated condition. The wear behavior was considerably improved to compare with this in dry sliding, while the oil adsorbed layer limited the transfer of the PTFE to the steel counter face during the sliding test. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PTFE" title="PTFE">PTFE</a>, <a href="https://publications.waset.org/abstracts/search?q=composite" title=" composite"> composite</a>, <a href="https://publications.waset.org/abstracts/search?q=bronze" title=" bronze"> bronze</a>, <a href="https://publications.waset.org/abstracts/search?q=MoS2" title=" MoS2"> MoS2</a>, <a href="https://publications.waset.org/abstracts/search?q=friction" title=" friction"> friction</a>, <a href="https://publications.waset.org/abstracts/search?q=wear" title=" wear"> wear</a>, <a href="https://publications.waset.org/abstracts/search?q=oil-lubrication" title=" oil-lubrication"> oil-lubrication</a> </p> <a href="https://publications.waset.org/abstracts/12663/tribological-behavior-of-ptfe-composites-used-for-guide-rings-of-hydraulic-actuating-cylinders-under-oil-lubricated-condition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12663.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">303</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">209</span> The Lord of the Rings in Brazilian Portuguese: Issues of Authorship in Translation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Caroline%20Almeida%20Santos">Caroline Almeida Santos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This presentation is based on my ongoing PhD research, a diachronic study that covers the entire history of publication of The Lord of the Rings in Brazilian Portuguese, from its first translation in the 1970s, the second translation in 1994, and the most recent one, from 2020. The main objective is to understand how the language used in translations evolved to more closely consider author J.R.R. Tolkien’s guidelines for translators of his work, established in his Guide to the Names in The Lord of the Rings (1975). Given the degree of freedom taken by both publisher and translators in the first translation of the novel, and that subsequent translations explicitly refer to the author's instructions, notable disparities between the translators’ choices may be observed; these may shed light on how evolving concepts of intellectual property, and hierarchical conceptions of authorship collectively influence linguistic choices and stylistic variations in translation. This study uses digital tools to identify key terms (featured in the aforementioned Guide) in the three translations for a comparative analysis of the translator's linguistic choices. It is expected that the analysis of these terms will reveal differences in the translators' view on the source text that might point to broader trends in literary translation when it comes to adherence to the linguistic features of the source text. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=literary%20translation" title="literary translation">literary translation</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20lord%20of%20the%20rings" title=" the lord of the rings"> the lord of the rings</a>, <a href="https://publications.waset.org/abstracts/search?q=brazilian%20portuguese%20translation" title=" brazilian portuguese translation"> brazilian portuguese translation</a>, <a href="https://publications.waset.org/abstracts/search?q=comparative%20linguistic%20analysis" title=" comparative linguistic analysis"> comparative linguistic analysis</a> </p> <a href="https://publications.waset.org/abstracts/198277/the-lord-of-the-rings-in-brazilian-portuguese-issues-of-authorship-in-translation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/198277.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">13</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">208</span> Enhancing Health Information Management with Smart Rings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bhavishya%20Ramchandani">Bhavishya Ramchandani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A little electronic device that is worn on the finger is called a smart ring. It incorporates mobile technology and has features that make it simple to use the device. These gadgets, which resemble conventional rings and are usually made to fit on the finger, are outfitted with features including access management, gesture control, mobile payment processing, and activity tracking. A poor sleep pattern, an irregular schedule, and bad eating habits are all part of the problems with health that a lot of people today are facing. Diets lacking fruits, vegetables, legumes, nuts, and whole grains are common. Individuals in India also experience metabolic issues. In the medical field, smart rings will help patients with problems relating to stomach illnesses and the incapacity to consume meals that are tailored to their bodies' needs. The smart ring tracks all bodily functions, including blood sugar and glucose levels, and presents the information instantly. Based on this data, the ring generates what the body will find to be perfect insights and a workable site layout. In addition, we conducted focus groups and individual interviews as part of our core approach and discussed the difficulties they're having maintaining the right diet, as well as whether or not the smart ring will be beneficial to them. However, everyone was very enthusiastic about and supportive of the concept of using smart rings in healthcare, and they believed that these rings may assist them in maintaining their health and having a well-balanced diet plan. This response came from the primary data, and also working on the Emerging Technology Canvas Analysis of smart rings in healthcare has led to a significant improvement in our understanding of the technology's application in the medical field. It is believed that there will be a growing demand for smart health care as people become more conscious of their health. The majority of individuals will finally utilize this ring after three to four years when demand for it will have increased. Their daily lives will be significantly impacted by it. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=smart%20ring" title="smart ring">smart ring</a>, <a href="https://publications.waset.org/abstracts/search?q=healthcare" title=" healthcare"> healthcare</a>, <a href="https://publications.waset.org/abstracts/search?q=electronic%20wearable" title=" electronic wearable"> electronic wearable</a>, <a href="https://publications.waset.org/abstracts/search?q=emerging%20technology" title=" emerging technology"> emerging technology</a> </p> <a href="https://publications.waset.org/abstracts/175734/enhancing-health-information-management-with-smart-rings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175734.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">69</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">207</span> Prime Graphs of Polynomials and Power Series Over Non-Commutative Rings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Walaa%20Obaidallah%20Alqarafi">Walaa Obaidallah Alqarafi</a>, <a href="https://publications.waset.org/abstracts/search?q=Wafaa%20Mohammed%20Fakieh"> Wafaa Mohammed Fakieh</a>, <a href="https://publications.waset.org/abstracts/search?q=Alaa%20Abdallah%20Altassan"> Alaa Abdallah Altassan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Algebraic graph theory is defined as a bridge between algebraic structures and graphs. It has several uses in many fields, including chemistry, physics, and computer science. The prime graph is a type of graph associated with a ring R, where the vertex set is the whole ring R, and two vertices x and y are adjacent if either xRy=0 or yRx=0. However, the investigation of the prime graph over rings remains relatively limited. The behavior of this graph in extended rings, like R[x] and R[[x]], where R is a non-commutative ring, deserves more attention because of the wider applicability in algebra and other mathematical fields. To study the prime graphs over polynomials and power series rings, we used a combination of ring-theoretic and graph-theoretic techniques. This paper focuses on two invariants: the diameter and the girth of these graphs. Furthermore, the work discusses how the graph structures change when passing from R to R[x] and R[[x]]. In our study, we found that the set of strong zero-divisors of ring R represents the set of vertices in prime graphs. Based on this discovery, we redefined the vertices of prime graphs using the definition of strong zero divisors. Additionally, our results show that although the prime graphs of R[x] and R[[x]] are comparable to the graph of R, they have different combinatorial characteristics since these extensions contain new strong zero-divisors. In particular, we find conditions in which the diameter and girth of the graphs, as they expand from R to R[x] and R[[x]], do not change or do change. In conclusion, this study shows how extending a non-commutative ring R to R[x] and R[[x]] affects the structure of their prime graphs, particularly in terms of diameter and girth. These findings enhance the understanding of the relationship between ring extensions and graph properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=prime%20graph" title="prime graph">prime graph</a>, <a href="https://publications.waset.org/abstracts/search?q=diameter" title=" diameter"> diameter</a>, <a href="https://publications.waset.org/abstracts/search?q=girth" title=" girth"> girth</a>, <a href="https://publications.waset.org/abstracts/search?q=polynomial%20ring" title=" polynomial ring"> polynomial ring</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20series%20ring" title=" power series ring"> power series ring</a> </p> <a href="https://publications.waset.org/abstracts/192430/prime-graphs-of-polynomials-and-power-series-over-non-commutative-rings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192430.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">31</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">206</span> Search for APN Permutations in Rings ℤ_2×ℤ_2^k</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Panario">Daniel Panario</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Santana%20de%20Freitas"> Daniel Santana de Freitas</a>, <a href="https://publications.waset.org/abstracts/search?q=Brett%20Stevens"> Brett Stevens</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Almost Perfect Nonlinear (APN) permutations with optimal resistance against differential cryptanalysis can be found in several domains. The permutation used in the standard for symmetric cryptography (the AES), for example, is based on a special kind of inversion in GF(28). Although very close to APN (2-uniform), this permutation still contains one number 4 in its differential spectrum, which means that, rigorously, it must be classified as 4-uniform. This fact motivates the search for fully APN permutations in other domains of definition. The extremely high complexity associated to this kind of problem precludes an exhaustive search for an APN permutation with 256 elements to be performed without the support of a suitable mathematical structure. On the other hand, in principle, there is nothing to indicate which mathematically structured domains can effectively help the search, and it is necessary to test several domains. In this work, the search for APN permutations in rings ℤ2×ℤ2k is investigated. After a full, exhaustive search with k=2 and k=3, all possible APN permutations in those rings were recorded, together with their differential profiles. Some very promising heuristics in these cases were collected so that, when used as a basis to prune backtracking for the same search in ℤ2×ℤ8 (search space with size 16! ≅244), just a few tenths of a second were enough to produce an APN permutation in a single CPU. Those heuristics were empirically extrapolated so that they could be applied to a backtracking search for APNs over ℤ2×ℤ16 (search space with size 32! ≅2117). The best permutations found in this search were further refined through Simulated Annealing, with a definition of neighbors suitable to this domain. The best result produced with this scheme was a 3-uniform permutation over ℤ2×ℤ16 with only 24 values equal to 3 in the differential spectrum (all the other 968 values were less than or equal 2, as it should be the case for an APN permutation). Although far from being fully APN, this result is technically better than a 4-uniform permutation and demanded only a few seconds in a single CPU. This is a strong indication that the use of mathematically structured domains, like the rings described in this work, together with heuristics based on smaller cases, can lead to dramatic cuts in the computational resources involved in the complexity of the search for APN permutations in extremely large domains. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=APN%20permutations" title="APN permutations">APN permutations</a>, <a href="https://publications.waset.org/abstracts/search?q=heuristic%20searches" title=" heuristic searches"> heuristic searches</a>, <a href="https://publications.waset.org/abstracts/search?q=symmetric%20cryptography" title=" symmetric cryptography"> symmetric cryptography</a>, <a href="https://publications.waset.org/abstracts/search?q=S-box%20design" title=" S-box design"> S-box design</a> </p> <a href="https://publications.waset.org/abstracts/145556/search-for-apn-permutations-in-rings-2-2k" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145556.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">166</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">205</span> High Frequency Rotary Transformer Used in Synchronous Motor/Generator of Flywheel Energy Storage System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20Lu">J.

The SESM can eliminate and reduce rare earth permanent magnet (REPM) usage and provide a better performance in renewable energy systems. However, the major drawback of such SESM is the necessity of brushes and slip rings to supply the field current, which increases the maintenance cost and operation reliability. To overcome these problems, an HFRT integrated with SiC semiconductor devices can replace brushes and slip rings in the SESM. The proposed HFRT features a high-frequency magnetic ferrite for both the stationary part as the transformer primary and the rotating part as the transformer secondary, as well as an air gap, allowing safe operation at high rotational speeds. Hence, this rotary transformer can enable the adoption of a wound rotor synchronous machine (WRSM). The HFRT, working at over 100kHz operating frequency, exhibits excellent performance of power efficiency and significant size reduction. The experimental validations to support the theoretical findings have been provided. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brushes%20and%20slip%20rings" title="brushes and slip rings">brushes and slip rings</a>, <a href="https://publications.waset.org/abstracts/search?q=flywheel%20energy%20storage" title=" flywheel energy storage"> flywheel energy storage</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20frequency%20rotary%20transformer" title=" high frequency rotary transformer"> high frequency rotary transformer</a>, <a href="https://publications.waset.org/abstracts/search?q=separately%20excited%20synchronous%20machine" title=" separately excited synchronous machine"> separately excited synchronous machine</a> </p> <a href="https://publications.waset.org/abstracts/188753/high-frequency-rotary-transformer-used-in-synchronous-motorgenerator-of-flywheel-energy-storage-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188753.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">55</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">204</span> Rings Characterized by Classes of Rad-plus-Supplemented Modules</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manoj%20Kumar%20Patel">Manoj Kumar Patel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we introduce and give various properties of weak* Rad-plus-supplemented and cofinitely weak* Rad-plus-supplemented modules over some special kinds of rings, in particular, artinian serial ring and semiperfect ring.

Recognizing that HRM is crucial for maximizing organizational performance, the study aims to evaluate its application within Greek law enforcement. A quantitative-descriptive survey was conducted, involving 996 executives from Greek Law Enforcement Agencies (477 from the Hellenic Police and 519 from the Hellenic Coast Guard), through random sampling. The survey, revealed significant concerns regarding the minimal implementation of HRM practices, in both agencies. The findings indicate that HRM practices, such as HR planning, recruitment, job position, selection, training and development, personnel management, compensation, labor relations and health and safety, are minimally applied. Neither the Hellenic Police nor the Hellenic Coast Guard appears to follow a comprehensive HRM plan. The study, contributes both theoretically and practically by highlighting the lack of HRM implementation in these agencies. The data suggest that by adopting strategic HRM practices, these organizations can enhance personnel performance and better fulfill their societal roles. Future research should extend to law enforcement agencies in other countries to draw more representative conclusion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coastguard" title="coastguard">coastguard</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20resources%20management" title=" human resources management"> human resources management</a>, <a href="https://publications.waset.org/abstracts/search?q=law%20enforcement%20agencies" title=" law enforcement agencies"> law enforcement agencies</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20management" title=" performance management"> performance management</a>, <a href="https://publications.waset.org/abstracts/search?q=police" title=" police"> police</a> </p> <a href="https://publications.waset.org/abstracts/186658/implementation-of-human-resource-management-in-greek-law-enforcement-agencies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186658.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">49</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">201</span> Study of Complex (CO) 3Ti (PHND) and CpV (PHND) (PHND = Phénanthridine)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Akila%20Tayeb-Benmachiche">Akila Tayeb-Benmachiche</a>, <a href="https://publications.waset.org/abstracts/search?q=Saber-Mustapha%20Zendaoui"> Saber-Mustapha Zendaoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Salah-Eddine%20Bouaoud"> Salah-Eddine Bouaoud</a>, <a href="https://publications.waset.org/abstracts/search?q=Bachir%20Zouchoune"> Bachir Zouchoune </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The variation of the metal coordination site in π-coordinated polycyclic aromatic hydrocarbons (PAH) corresponds to the haptotropic rearrangement or haptotropic migration in which the metal fragment MLn is considered as the moveable moiety that is shifted between two rings of polycyclic or heteropolycyclic ligands. These structural characteristics and dynamical properties give to this category of transition metal complexes a considerable interest. We have investigated the coordination and the haptotropic shifts of (CO)3Ti and CpV moieties over the phenanthridine aromatic system and according to the metal atom nature. The optimization of (CO)3Ti(PHND) and CpV(PHND), using the Amsterdam Density Functional (ADF) program, without a symmetrical restriction of geometry gives an η6 coordination mode of the C6 and C5N rings, which in turn give rise to a six low-lying deficient 16-MVE of each (CO)3Ti(PHND) and CpV(PHND) structure (three singlet and three triplet state structures for Ti complexes and three triplet and three quintet state structures for V complexes). Thus, the η6–η6 haptotropic migration of the metal fragment MLn from the terminal C6 ring to the central C5N ring has been achieved by a loss of energy. However, its η6–η6 haptotropic migration from central C5N ring to the terminal C6 rings has been accomplished by a gain of energy. These results show the capability of the phenanthridine ligand to adapt itself to the electronic demand of the metal in agreement with the nature of the metal–ligand bonding and demonstrate that this theoretical study can also be applied to large fused π-systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electronic%20structure" title="electronic structure">electronic structure</a>, <a href="https://publications.waset.org/abstracts/search?q=bonding%20analysis" title=" bonding analysis"> bonding analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=density%20functional%20theory" title=" density functional theory"> density functional theory</a>, <a href="https://publications.waset.org/abstracts/search?q=coordination%20%20chemistry%20haptotropic%20migration" title=" coordination chemistry haptotropic migration "> coordination chemistry haptotropic migration </a> </p> <a href="https://publications.waset.org/abstracts/38303/study-of-complex-co-3ti-phnd-and-cpv-phnd-phnd-phenanthridine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38303.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">308</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">200</span> The Amorphousness of the Exposure Sphere</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nipun%20Ansal">Nipun Ansal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> People guard their beliefs and opinions with their lives. Beliefs that they’ve formed over a period of time, and can go to any lengths to defy, desist from, resist and negate any outward stimulus that has the potential to shake them. Cognitive dissonance is term used to describe it in theory. And every human being, in order to defend himself from cognitive dissonance applies 4 rings of defense viz. Selective Exposure, Selective Perception, Selective Attention, and Selective Retention. This paper is a discursive analysis on how the onslaught of social media, complete with its intrusive weaponry, has amorphized the external ring of defense: the selective exposure. The stimulus-response model of communication is one of the most inherent model that encompasses communication behaviours of children and elderly, individual and masses, humans and animals alike. The paper deliberates on how information bombardment through the uncontrollable channels of the social media, Facebook and Twitter in particular, have dismantled our outer sphere of exposure, leading users online to a state of constant dissonance, and thus feeding impulsive action-taking. It applies case study method citing an example to corroborate how knowledge generation has given in to the information overload and the effect it has on decision making. With stimulus increasing in number of encounters, opinion formation precedes knowledge because of the increased demand of participation and decrease in time for the information to permeate from the outer sphere of exposure to the sphere of retention, which of course, is through perception and attention.

The process of climate change, especially changes in temperature and precipitation, is the most important issue in the environmental sciences. Climate change means changing the averages in the long run. Iran is located in arid and semi-arid regions due to its proximity to the equator and its location in the subtropical high pressure zone. In this respect, the Hyrcanian forest is a green necklace between the Caspian Sea and the south of the Alborz mountain range. In the forty-third session of UNESCO, it was registered as the second natural heritage of Iran. Beech is one of the most important tree species and the most industrial species of Hyrcanian forests. In this research, using dendroclimatology, the width of the tree ring, and climatic data of temperature and precipitation from Shanderman meteorological station located in the study area, And non-parametric Mann-Kendall statistical method to investigate the trend of climate change over a time series of 202 years of growth ringsAnd Pearson statistical method was used to correlate the growth of "ring" growth rings of beech trees with climatic variables in the region. The results obtained from the time series of beech growth rings showed that the changes in beech growth rings had a downward and negative trend and were significant at the level of 5% and climate change occurred. The average minimum, medium, and maximum temperatures and evaporation in the growing season had an increasing trend, and the annual precipitation had a decreasing trend. Using Pearson method during fitting the correlation of diameter of growth rings with temperature, for the average in July, August, and September, the correlation is negative, and the average temperature in July, August, and September is negative, and for the average The average maximum temperature in February was correlation-positive and at the level of 95% was significant, and with precipitation, in June the correlation was at the level of 95% positive and significant. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=dendroclimatology" title=" dendroclimatology"> dendroclimatology</a>, <a href="https://publications.waset.org/abstracts/search?q=hyrcanian%20forest" title=" hyrcanian forest"> hyrcanian forest</a>, <a href="https://publications.waset.org/abstracts/search?q=beech" title=" beech"> beech</a> </p> <a href="https://publications.waset.org/abstracts/155212/study-of-climate-change-process-on-hyrcanian-forests-using-dendroclimatology-indicators-case-study-of-guilan-province" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155212.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">107</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">197</span> The Design of Acoustic Horns for Ultrasonic Aided Tube Double Side Flange Making</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kuen-Ming%20Shu">Kuen-Ming Shu</a>, <a href="https://publications.waset.org/abstracts/search?q=Jyun-Wei%20Chen"> Jyun-Wei Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Encapsulated O-rings are specifically designed to address the problem of sealing the most hostile chemicals and extreme temperature applications.

As a result, the degradation of high-speed digital circuits due to signal integrity issues such as coupling effects, clock feedthrough, crosstalk noise and delay uncertainty noise. Crosstalk noise in VLSI interconnects is a major concern and reduction in VLSI interconnect has become more important for high-speed digital circuits. It is the most effectively considered in Deep Sub Micron (DSM) and Ultra Deep Sub Micron (UDSM) technology. Increasing spacing in-between aggressor and victim line is one of the technique to reduce the crosstalk. Guard trace or shield insertion in-between aggressor and victim is also one of the prominent options for the minimization of crosstalk. In this paper, far end crosstalk noise is estimated with mutual inductance and capacitance RLC interconnect model. Also investigated the extent of crosstalk in capacitive and inductively coupled interconnects to minimizes the same through shield insertion technique. <p class="card-text"><strong>Keywords:</strong>
