Modelling of Fuzzy Expert System for an Assessment of Security Information Management System UIS (University Information System)

Several methodologies based on the international standard ISO/IEC 27001 have been developed for modelling information security management systems within higher education. This paper transformed the ISO/IEC 27001 standard into a questionnaire, which was sent digitally to about 100 universities in Bosnia and Herzegovina, and to the EU, Norway and the USA. The questions are arranged by levels, and the levels have their numerical weights, derived from individual questions in the levels themselves. Otherwise, the questions are asked with Yes or No and thus are reduced to binary variables. The rules necessary for the functioning of the system have been calculated. The fuzzy logic method represents a new approach to the problems of managing complex systems, which is very difficult to describe with a certain mathematical model, as well as in systems with a large number of inputs and outputs where there are unclear interactions. Risk assessment is a major part of the ISMS process. Traditional risk calculation models are based on the application of probability and classical set theory. Here, we have converted the risk assessment into a system rating of 5 to 10 numerically or from five to ten descriptively. We perform fuzzy optimization by finding the values of the input parameters of a complex simulated system, which results in the desired output. We use the fuzzy logic controller to execute fuzzy inference rules from the fuzzy rule database in determining congestion parameters, obtaining warning information and appropriate action. Simulating the situation of an advanced system that evaluates the protection quality of such a system with fuzzy logic, we use MATLAB. The paper combines the original Visual Basic programming language and MATLAB\u27s Fuzzy Toolbox, to solve the complex problem of assessing compliance with the ISO/IEC 27001 standard, as one of the main standards for information systems security modelling. University information systems were used, but it is also applicable to all other information systems. The evaluation has been done for several universities and it has been proven that the system evaluates correctly, but these universities must not be publicly named. There was no such approach in the use of fuzzy logic and on such systems, and that is the originality of this work

Automation and Artificial Intelligence in Software Engineering: Experiences, Challenges, and Opportunities

Automation and Artificial Intelligence have a transformative influence on many sectors, and software engineers are the actors who engineer this transformation. On the other hand, there is little knowledge of how automation and Artificial Intelligence impact software engineering practice. To answer this question, we conducted semi-structured interviews with experienced software practitioners across frontend and backend development, DevOps, R&D, integration, and leadership positions. Our findings reveal 1) automation to appear as micro-automation in the sense of automation of tiny and specific tasks, 2) automation as a side product of work, and bottom-up driven in software engineering, and 3) automation as a possible cause for cognitive overhead due to automatically generated notifications. Furthermore, we notice that our interview participants do not expect automation and artificial intelligence tools to substantially change software engineering\u27s essence in the foreseeable future

Efikasnost fungicida Vivando (A.S. Metrafenon) u suzbijanju pepelnice vinove loze u Crnoj Gori

Efficacy of the fungicide based on metrafenone (Vivando) in control of the pathogenic fungus Erysiphe necator, the causal agent of grapevine powdery mildew, has been studied at the experimental field of the Biotechnical Faculty in Podgorica (Podgorica's vineyards area). The experiments were conducted in 2011 and 2012, and were set according to the EPPO methods. The assessment of efficacy was performed on leaves and clusters of grapes. During 2011, nine treatments were performed, and in 2012 five. The obtained efficiency in both years amounted 100%, although the intensity of the disease varied in different experimental years. In 2011, on control plots disease intensity was high - 98.25% on leaves and 98.03% on clusters, and in 2012 was quite lower - 65.83% on leaves and 62.05% on clusters. The active substance metrafenone exhibited high efficiency at different, very high, intensities of the disease.Na oglednom imanju Biotehničkog fakulteta u Podgorici (Podgoričko vinogorje) ispitivana je efikasnost fungicida na bazi metrafenona (Vivando) u suzbijanju fitopatogene gljive Erysiphe necator, prouzrokovača pepelnice vinove loze. Eksperimenti su izvedeni tokom 2011. i 2012. godine, a postavljeni su po metodama EPPO. Ocjena efikasnosti obavljena je na listovima i grozdovima. Tokom 2011. obavljeno je devet tretiranja, a u 2012. pet. Dobijena efikasnost u obe godine je iznosila 100%, iako se intenzitet oboljenja razlikovao u eksperimentalnim godinama. Tokom 2011. na kontrolnim parcelama iznosio je visokih 98,25% na listovima i 98,03 na grozdovima, a u 2012. bio je dosta niži - na listovima 65,83%, a na grozdovima 62,50%. Aktivna supstanca metrafenon ispoljila je visoku efikasnost pri različitim, vrlo visokim, intenzitetima oboljenja

Explaining the Decline in Early Mortality in Men and Women With Type 2 Diabetes: A population-based cohort study

OBJECTIVE—The purpose of this study was to test the hypothesis that changing utilization of lipid-lowering, antihypertensive, and oral hypoglycemic drugs may be associated with trends in all-cause mortality in men and women with type 2 diabetes

Volatility spillover effect in Western Balkans

This article examines volatility spillover among Western Balkan’s stock markets and selected developed markets. If there is an evidence of weak linkage between various markets, then there are potential benefits that could arise from international diversification. However, if we analyse the relationship between two markets that are different in terms of their economic development, and if there is a strong connection between them, market shocks from the developed markets can have an impact on the frontier/emerging markets. Market integration can be indicated with returns linkage and transmission of shocks and volatility between markets. Hence, this can have implications for investment strategies. It is found that there is statistically significant regional spillover between countries of the Western Balkan region. Also, there is global spillover between developed markets and this region as well. Furthermore, there is evidence that Western Balkan’s markets are late in response to important market events, and that can be used when formulating investment strategy

Simulation of Robotic Tasks with VALIP System - Practical Application

Source at https://annals.fih.upt.ro/.In manufacturing engineering, man-machine interaction has gone from typical online programming techniques into virtual reality based offline programming methodologies. Today, a wide range of offline software tools is used to imitate, simulate and control real manufacturing systems. However, these new methodologies lack capability when it comes to human-machine communication. This paper aims to introduce a software platform, called VALIP, where users can build, share and manipulate 3D content, and collaboratively interact with processes in a 3D context, while the participating hardware and software devices can be spatially and/or logically distributed and connected together via the Internet. This unique approach makes the VALIP outstanding among its competitors. The paper also presents a practical solution to a production task

Pricing Weather Derivatives

ABSTRACT Weather makes influence on our daily lives and choices and has substantial impact on corporate revenues and earnings. The impact of weather on business activities is significant and varies both geographically and seasonally. Almost every industry is affected by the weather, among which is agriculture, energy, entertainment, travel, constructions. It is been stated that "weather is not just an environmental issue; it is major economic factor". Weather risk is localized, and cannot be controlled. Despite advances in meteorological science, weather still cannot be predicted precisely and consistently. As a tool for managing weather risk, special kind of derivative securities was established - weather derivatives. Opportunity to trade on weather posed challenge for financial and risk management professionals; which include pricing analysis, and portfolio management. Market for these securities is incomplete market, because the underlying security (weather) is not tradable asset. The aim of this dissertation is to address the problem of pricing weather derivative securities and create a model that can be used for valuation of such securities written on Paris
