Optimizing cloud service provider selection with firefly-guided fuzzy decision support system for smart cities

Businesses that want to benefit from cloud computing must choose a Cloud Service Provider (CSP). Cost, performance, Reliability, security, and SLAs must be evaluated during the decision process. CSP assessment is tough because of uncertainties and erroneous data. Fuzzy logic and the firefly optimization technique have been proposed in this paper to achieve optimal results based on diverse components. The proposed methodology uses consumer, service provider, and public reviews based on the three elements. These components' ratings can be used to analyze efficiency. Simple fuzzy logic is inferior to optimized fuzzy logic, according to experiments. The Firefly Optimized Fuzzy DSS is compared against non-optimized fuzzy decision-making systems and standard optimization methods. The results show that the proposed model is better for selecting the best CSP based on many parameters and managing assessment uncertainty. Fuzzy logic and optimization methods provide more nuanced and precise decision-making that accounts for subjective assessments and confusing facts. Businesses can make informed choices and ensure their CSP needs are satisfied with the approach. Finally, the Firefly Optimized Fuzzy Decision Support System offers a new perspective on cloud service provider selection by merging fuzzy logic with optimization. The system's ability to handle poor evaluations and ambiguity makes it ideal for CSP selection's complex decision-making process. This paper helps build decision support systems for choosing a cloud service provider and has substantial implications for firms seeking successful cloud computing solutions. This research work's conclusions have major implications for corporations and organizations searching for the finest cloud service providers. CSP-related real-world datasets are tested experimentally.

SMALL PSEUDO QUASI PRINCIPALLY INJECTIVE ACTS

In act theory, Pseudo injective acts and their generalizations are essential. As a result, the purpose of this work is to give a generalization of pseudo quasi principally injective acts specifically small pseudo quasi principally injective acts. Besides, the concept of a small pseudo injective was presented, which can be employed later. If each S-monomorphism from a small M-cyclic sub-act of M\textsubscript{S} to N\textsubscript{S} is extended to S-homomorphism from M\textsubscript{S} to N\textsubscript{S}, An S-act N\textsubscript{S} is called a small pseudo-M-principally-injective (for simply small pseudo-MP-injective). Also, if an S-act M\textsubscript{S} is a small pseudo-MP-injective act, then it is called small pseudo quasi principally injective. This form of generalization is given several new characterizations and properties. Following that conditions are shown under which sub acts inherit the property of small pseudo quasi principally injectivity. Furthermore, the connection between the classes of small pseudo quasi principally injective S-acts with classes of injectivity is addressed, and as a result, requirements to coincide these classes are shown. Our work's conclusions have been explained.

Soviet Georgians between Tbilisi and Moscow

Erik R. Scott, Familiar Strangers: Georgian Diaspora and the Evolution of the Soviet Empire. 352 pp. New York: Oxford University Press, 2016. ISBN-13 978-0199396375. $74.00. Tens of millions of Soviet citizens lived among a group to which they did not belong. Upheaval resulting from war, revolution, aggressive industrialization drives, and forced migrations resulted in significant population mixing. Erik Scott, the author of a new book on Georgians living within Russia, reminds us just what a key role various diasporas played in the formation and development of the Soviet Union. Scott stresses: The Soviet Union was not simply a federation of nationalities confined to titular republics. Instead, it was an empire of mobile diasporas that transcended the borders of the republics, intermixed, and helped construct a truly multiethnic (3). To examine this process, Scott offers his case study of the Georgian diaspora, analyzing the political, social, cultural, and economic aspects of its development. An expansive chronological frame--the entire Soviet period with excursions into the late imperial and post-Soviet periods--inspires particular confidence in the work's conclusions, facilitating a convincing investigation of both the ephemeral (political) and more fixed (sociocultural) qualities of the Georgian diaspora. An introductory theoretical chapter gives an overview of various theoretical frames concerning diasporas while simultaneously demonstrating the difficulty of the project. Where might one find sources attesting to the intangible processes of social change? What are the parameters of the analytical frames that will adequately capture their essence? These questions present potential pitfalls for every historian who endeavors to employ an interdisciplinary approach, and Scott meets their challenge, successfully balancing theory and historical narrative. A fundamental triumph of the work lies in having identified a particularly fertile topic of investigation. Georgian diaspora in Russia, while not particularly sizable in terms of population, was highly active; elements of Georgian culture and tradition spread easily within a foreign cultural sphere, especially in cosmopolitan Moscow. In Scott's language, Georgians were seen as strangers, and even the most familiar strangers. This diaspora was organically integrated into an alien society on which it exerted measurable influence. Why was this the case? What role did the Georgian diaspora play in the development of the Soviet empire? These important and undertreated questions focus the author's work. Scott shows that the fate of the Georgian diaspora was marked by relative success, even during the more tragic chapters of Soviet history. This contrasts especially starkly with the difficulties faced by many other diasporas within the Soviet Union. Stalin and his regime considered the various external diasporas (those that had their roots beyond the borders of the USSR) to be threatening, a potential source of espionage or collaborationism. Between the late 1920s and the 1930s, these groups were subject to periodic repressions on the basis of nationality, which found their apogee later that decade in massive NKVD national operations (1937-38). Hundreds of thousands from among more than a dozen ethnic groups (Germans, Poles, Latvians, Greeks, Finns, Bulgarians, etc.) suffered as a result of these operations. In addition, the Korean population of the Russian Far East was exiled in this period. During World War II, Poles, a notionally allied people, were spared; Soviet Germans, in contrast, faced the brunt of repression on the basis of nationality, suffering mass deportation. postwar years saw the weight of persecution fall on the Jewish population. A convenient lightning rod for social discontent, Jews took on the role that enemies of the people and wreckers had played in the 1930s and were, in Stalin's view, the agents of a newly founded Israeli state and, more broadly, American imperialism. …

A Citation Analysis of ETD and Non-ETD Producing Authors

This work takes advantage of the current status of the development of electronic theses and dissertations (ETDs) at the University of Louisville to reexamine a previous study that compared ETD and non-ETD producing authors' use of the professional literature. As with the previous study, this effort found no noticeable difference in the two groups of doctoral students' referencing behavior. This review of 100 dissertations and their 13,926 references confirmed the previous work's conclusions that doctoral students' publication format is not reflective of their library research. These findings suggest that librarians need not amend their efforts in response to academia's on-going development of ETDs and that differences between ETD and non-ETD authors are unrelated to their utilization of library resources.

Rousseau and the Reserve of Nature: A Rejoinder to Derrida

This article re-examines Derrida's presentation of Rousseau's philosophy of nature and culture in De la grammatologie to interrogate that work's conclusions about the inescapability of the logic of the supplement . Drawing on a close reading of the first book of Emile , it argues that Rousseau's ontological commitments neither originate from nor entail a metaphysics of pure presence. The challenge to Derrida derives from the category of habit understood as an ontological principle that structures the conceptualization of nature in Emile . Rousseau's formulation of nature as a reserve , a theory of innateness as sleeping potentiality, indicates not a 'presence' but a store of potencies bearing an indeterminate ontology. As well as a capacity and an agency, nature is also a state of being. Habit, meanwhile, reveals the two senses of nature — as teleology and being — and mediates between them. Nature, for its part, arises as the outcome, as well as the origin and determination, of habit. This signifies that nature and culture are not the terms of a dichotomy but arise simultaneously when habit draws from nature's reserve. The article concludes that Derrida simplifies and exploits Rousseau by reading him through the distorting lens of Levi-Strauss's structuralist anthropology.

Uma investigação sobre o ator consumidor na rede de pirataria e uma proposta de alternativa de estratégia de combate

O objetivo deste artigo é investigar as percepções e representações sociais do consumidor na rede de pirataria e propor uma alternativa de princípio estratégico de combate a esse comércio ilegal a partir de um modelo de rede que inclui o ator consumidor. A afirmativa básica é que a pirataria se organiza no formato de rede, onde o consumidor é um ator importante, que mantém a rede em razão de suas específicas percepções e representações sociais sobre o governo, sobre as empresas fabricantes, sobre os camelôs e sobre si próprio, percepções essas que abrangem mais do que o preço, que é o fator mais pesquisado no tema de pirataria. A base teórica de apoio é o conceito de rede social que existe como pano de fundo nas redes de negócios, com seus fatores de interdependência, comprometimento, expectativas e representações sociais, bem como o conceito de nó, que é a unidade de estudo das redes. Realizou-se uma pesquisa com grupos de adolescentes e adultos, e os dados mostraram a presença de representações sociais positivas sobre a ponta da pirataria, que é o camelô, e representações sociais negativas sobre o governo e as empresas que combatem a ilegalidade. Nas conclusões, mostra-se que há um ganho de compreensão quando se inclui o ator consumidor na rede, tanto no que se refere à manutenção do comércio pirata quanto às estratégias de combate. Como conclusão secundária importante, considerando os resultados abaixo do esperado por parte do governo no combate à pirataria, sugere-se um princípio estratégico a partir das redes sociais. A premissa da proposta é que só se combate uma rede a partir de outra rede, conforme atestam alguns exemplos de organizações sociais e comerciais.

A phenomenological theory of polycomponent interactions in non-ideal mixtures. Application to NH 3/H 2O and other working pairs

The paper proposes an original linear phenomenological theory (Ph T) of evolution physical mono-, bi- and particular polycomponent gas–liquid interactions with non-ideal mixture. The expressions of the phenomenological factors (entropy source, force, coefficient and coupled heat and mass transfer currents) are deduced. The theory is particularized to the NH 3/H 2O and other gas–liquid systems used in the thermal absorption technology. The work's conclusions are listed next. The paper raises the problem of ammonia bubble absorption which is difficult to answer with current theory of interface mass transfer and absorption as a surface phenomenon. The heat and mass transfer at the gas–liquid interface is governed by the thermodynamic force, which applies also to solid–liquid, solid–gas, or liquid–liquid, gas–gas type interactions and continuous or discontinuous media. The paper mentions a postulate referring to the force behavior approaching an ideal point, previously formulated by the author. According to its consequence, the mass and heat currents suffer an ideal point approaching (i.p.a.) effect, not mentioned so far in the specialized literature, consisting in a continuous increase of their absolute value by several percent (for a pure component), to several hundred times (for a binary system) when the interacting system approaches an ideal state, as compared to the values of states which are far from the same ideal point. In this way, “far from equilibrium” becomes synonymous to “low interaction”. The classic assessment of the interface mass transfer by analogy with heat transfer lacks basic physics. The (Ph T) satisfactorily explains the problem of ammonia bubble absorption. Absorption is a mass phenomenon, not a surface one. An intensive way of improving absorption is emphasized, which seeks to promote the i.p.a. effect appearance rather than the extensive way currently used, based on increasing gas–liquid interaction area. To this extent, the bubble absorber is hereby proposed for efficient absorption. The i.p.a. effect existence offers an additional chance for a satisfactory explanation of the Marangoni effect.

Unstable crack growth in a component subject to constant applied loads: The interaction between plasticity and geometrical effects

When a crack grows slowly by, for example, a stress corrosion mechanism, in a component that is subject to constant applied loads, it is possible that there will be a transition from slow growth to unstable nonenvironmentally-assisted growth. Earlier work has shown that, even though a material's resistance to nonenvironmentally-assisted crack growth may be only moderate, the transition should not occur unless plastic deformation traverses the ligament between the crack front and the opposite free surface, i.e. unless general yield occurs. The earlier work analyzed the model of an edge crack in a semi-infinite solid, and compared the extent of spread of plasticity with the solid width in the real situation, thereby neglecting the interaction between the plastic zone and the boundary opposite the crack in the real situation. This paper extends the scope of the earlier investigation by analyzing a model in which the interaction between plasticity and geometrical effects is accounted for in an accurate manner. Though it is shown that unstable nonenvironmentally-assisted growth can occur before general yield, such growth occurs so close to general yield that the earlier work's conclusions are essentially unchanged. The implications of the conclusions are discussed in relation to the empirical net-section stress approach for predicting failure in ductile materials.
