It has been observed that Nicotine Replacement Therapy (NRT) is one of the alternatives to control and reduce smoking addiction among smokers. Since the decision to choose the best NRT alternative involves uncertainty, ambiguity factors and diverse input datasets, thus, this paper proposes a fuzzy multi-criteria analysis (FMA) to overcome these issues. It focuses on how the fuzzy approach can unify the diversity of datasets based on NRT’s decision-making problem. The analysis done employed the advantage of the cost-benefit criterion to unify the mixture of dataset input. The performance matrix was utilised to derive the performance scores. An empirical example regarding the NRT’s decision-making problem was employed to illustrate the proposed approach. Based on the calculations, this analytical approach was found to be highly beneficial in terms of usability. It was also very applicable and efficient in dealing with the mixture of input datasets. Hence, the decision-making process can easily be used by experts and patients who are interested to join the therapy/cessation program.

This article introduces and examines a metric for the evaluation of the software testing process efficiency. The article examines the characteristics of the software testing process. The main activities within the process and the expected results are defined. A software metric for the evaluation of the testing efficiency is defined. The metric is based on the amount of bugs discovered during testing and bugs discovered by clients. The metric was applied to four projects of a single organization. The results from the metric were examined for correlation with the information needs for the metric.

We consider a (2+1)-D boundary value problem for degenerate hyperbolic equation, which is closely connected with transonic fluid dynamics. This problem was introduced by Protter in 1954 as a multi-dimensional analogue of the Darboux problem in the plain, which is known to be well-posed. However the (2+1)-D problem is overdetermined with infinitely many conditions necessary for its classical solvability and there exist generalized solutions of this problem with strong *** years we study the exact asymptotic behavior of such singular solutions. We offer a Riemann-Hadamard method for solving the problem instead of the used until now method of successive approximations for solving an equivalent integral equation. As result, we obtain a more convenient representation of the singular solutions giving more precise results in our investigation.

Numerous time series methods are used in environmental sciences allowing the detailed investigation of air pollution processes. The goal of this study is to present the empirical analysis of various aspects of stochastic modeling and in particular the ARIMA/SARIMA methods. The subject of investigation is air pollution in the town of Kardzhali, Bulgaria with 2 problematic pollutants – sulfur dioxide (SO2) and particulate matter (PM10). Various SARIMA Transfer Function models are built taking into account meteorological factors, data transformations and the use of different horizons selected to predict future levels of concentrations of the pollutants.
