Cloud Provider Selection Based on Accountability and Security Using Interval Valued Fuzzy TOPSIS

Cloud computing enables on-demand access to a public resource pool. Many businesses are migrating to the cloud due to its popularity and financial benefits. As a result, finding a suitable and best Cloud Service Provider is a difficult task for all cloud users. Many ranking systems, such as ANP, AHP and TOPSIS, have been proposed in the literature .However, many of the studies concentrated on quantitative data. But qualitative attributes are equally significant in many applications where the user is more concerned with the qualitative features.The implementation of MCDM approach for the ranking and the selection of the best player in the market as per the qualitative need of the cloud users like business organization or cloud brokers is the aim of this article. An ISO approved standard SMI framework is available for the evaluation of the CSPs.The authors have considered SMI attributes like accountability and security as the criteria for evaluation of the CSPs. The MCDM approach called IVF-TOPSIS that can handle the inherent vagueness in the cloud dataset is implemented in this work

Improvement of test methods and criteria for evaluation of resistance to flame propagation of long elements of the wiring system

The test methods for flame propagation of long elements of the electrical wiring system, in particular, cables, cable conduits and ducts, are analyzed, and differences in them are found in the test conditions and criteria for evaluating the resistance to flame propagation. Using a substrate of a wooden board covered with a layer of tissue paper with an areal density of (21±9) g/m2, adopted for testing other elements of the electrical wiring system, a cable was identified that is not resistant to flame propagation. It is proposed to use this substrate for testing the flame propagation of cables instead of a substrate made of a double layer of filter paper with a surface density of (80±15) g/m2. In one of three experiments, a cable that was not resistant to flame propagation was found based on the criterion of the presence of ignition of the substrate located under it. To reduce the risk of making an incorrect decision on compliance, it is proposed that the assessment of long elements of the wiring system be carried out according to the rules established for cable ducts, trays and ladders in EN 50085-1 and IEC 61537. For the AVVG cable with an outer diameter of 10 mm to 60 mm, when it touches the blue flame cone of 1 kW, the correlation coefficient of the dependence of the length of the charred part on the diameter was 0.969. For a distance of 100 mm between the sample and the burner along its axis, a correlation coefficient of 0.985 was obtained. It is proposed to test cables under the second condition recommended in IEC 60695-11-2. For two conduits, flame propagation was revealed when exposed to a 1 kW flame for 120 s and 240 s. However, for these pipelines, flame propagation did not occur under standard conditions of exposure to such a flame for 20 s and 25 s. To identify long elements of the wiring system that are not resistant to flame propagation, it is proposed to test them at a duration of exposure to a flame of 1 kW, established for cables in IEC 60332-1-2

The Philosopher's Corner

A minimalist view of theory will render it more accessible for a wider range of research questions. More accessible theory will facilitate constant improvement between representations predicting particular relationships among entities of interest in IS and observations of those relationships in practice. This is needed in IS to direct research energy toward knowledge that can lead to more effective and helpful interventions for computing technology stakeholders. The paper also addresses a range of anomalies created by prevailing traditional views of theory, particularly regarding the distinction between theory existence and theory level of support. Discussion includes identifying barriers to conversion to this view of theory as well as criteria for evaluation of proposed new theory.

ON THE SYSTEM OF QUANTITATIVE AND QUALITATIVE CRITERIA FOR EVALUATION OF THE EFFECTIVENESS OF LEGAL INSTRUMENTS FOR SECURING THE PROPERTY INTERESTS OF THE STATE, ECONOMIC ENTITIES AND CITIZENS

The purpose of the article is to propose a system of quantitative and qualitative criteria for assessing the effectiveness of legal instruments to ensure the property interests of the state, businesses and citizens. Achieving the goals of the article is possible through the use of general research methods and special methods of studying legal phenomena and processes. Among others, methods of induction and deduction, historical and comparative law, modeling, abstraction and others were used, which allowed to analyze the processes of protection of property and property relations in the economy, social sphere, foreign economic activity and propose criteria for assessing the impact of a normative legal act (NLA) on these processes and relationships. The application of the above methods of scientific knowledge allowed to propose the following conditionally quantitative criteria: the number of changes and additions made to the NLA; the number of appeals to law enforcement and judicial bodies due to the threat to the property interests of the state, business entities or citizens; dynamics of the number of “raider” attacks on property of the state, business entities and citizens; the number of references to NLA in the scientific and special professional legal literature; the number of views and downloads of NLA on the Internet; the level of support for the NLA among lawmakers, government officials and the business elite and society at large; and the following conditionally qualitative criteria: the form and structure of the NLA, as well as the legal technique of setting out its provisions; the level of confidence of domestic and especially foreign investors; the NLA has pro visions on liability for damage to property and property rights with a mandatory relationship with the rules of criminal and administrative law; the degree of compliance of the Ukrainian NLA and the level of its implementation with European and world standards. It is concluded that the given non-exclusive list of 10 criteria, none of which can be considered absolutely objective, in its entirety can be recognized as a system, the complexity of which will bring the assessment of the effectiveness of legal interests of the state, businesses and citizens to objective.

Evaluating biometrics by using a hybrid MCDM model

Biometrics has been developing for decades in diverse industries, such as consumer electronics, internet of things, financial industry, etc. The purpose of this research is to build a decision-making model to evaluate and improve the performances of biometrics for administrators to design and make suitable biometric systems. This paper adopts a hybrid multiple criteria decision making (MCDM) model, comprising decision-making trial and evaluation laboratory (DEMATEL), and DEMATEL-based analytic network process (called DANP) to probe into the interrelationship and influential weights among criteria of biometrics. According to DEMATEL technique, the empirical results indicate that criteria of biometrics have self-effect relationships. The dimension of biometrics that administrators of biometrics should enhance first when improving the performances is usability. The criterion of universality with the highest influencing value to systematically affect all other evaluation factors is what administrators of biometrics should comprehensively consider. In the top three criteria for evaluation by DANP, biometric systems with the most influential weight is the criterion that can be improved to have higher recognition rates for increasing the performances of biometrics, followed by biometric conditions and permanence.

Delivering Administrative Justice

This chapter examines administrative justice as a system, asking if justice is delivered (rather than ‘accessed’). The background issues are: What do people seek, and what is the incidence of problems? It notes the relevance of the Regulatory Delivery Model that is being applied to regulatory authorities. It then poses three criteria for evaluation of the system: (1) How do people identify and access information, advice, support, and assistance in solving their problems? (2) How do we ensure that dispute-resolution pathways are simple, effective, and cost-effective and deliver justice to people and organizations? (3) How do we identify systemic problems, and address them so as to reduce risk of future recurrence? The data available for answering those questions in relation to administrative justice in England and Wales do not support comfortable answers as to the functioning of current systems in various respects. Suggestions for future reform and research therefore arise.

A clinical laboratory's experience using GeneMatcher -- building stronger gene-disease relationships.

The use of whole-genome sequencing (WGS) has accelerated the pace of gene discovery and highlighted the need for open and collaborative data sharing in the search for novel disease genes and variants. GeneMatcher (GM) is designed to facilitate connections between researchers, clinicians, health-care providers and others to help in the identification of additional patients with variants in the same candidate disease genes. The Illumina Clinical Services Laboratory offers a WGS test for patients with suspected rare and undiagnosed genetic disease and regularly submits potential candidate genes to GM to strengthen gene-disease relationships. We describe our experience with GM, including criteria for evaluation of candidate genes, and our workflow for the submission and review process. We have made 69 submissions, 36 of which are currently active. Ten per cent of submissions have resulted in publications, with an additional 14 submissions part of ongoing collaborations and expected to result in a publication.
