Abstract: Methods and mathematical tools for formalization analysis and verification of SoftwareDefined? Network protocols are suggested in the paper. E-networks apparatus and linear temporal logics are proposed to be used as mathematical tools for modeling and analysis. These mathematical tools can be transparently used to analyze critical requirements and properties of Software-Defined? Networks implementation - OpenFlow? protocol. The suggested methodology is based on the modeling approach and sequence analysis of changes of OpenFlow? protocol elements states. Apparatus of E-networks models the element states of SDN implementation. Such approach allows taking into account the asynchronous nature of complex processes in OpenFlow? protocol and performing stateful inspection. The use of models of E-network allows analyzing such properties as reachability, boundedness, liveliness, find loops and deadlock. The given mathematical method also allows finding difference between specification and designed networks. The method is based on the verification of temporal logic within the context of relationships of satisfaction. Using temporal logic formalisms allows to analysis and verify inconsistent of specification’s requirements. For this purpose formalism was designed that allows checking out the requirements form different specification versions of OpenFlow? protocol.

Abstract: On the ground of relevant literature review the purpose of this paper is to demonstrate knowledge as power Dialogue strategies and similarities between organization and civilizations. Knowledge and Solution have many definitions and it is difficult to give a commonly accepted definition for them. Starting with the ideas of knowledge. Generally speaking, while knowledge is an intellectual product of the mental activity of human beings concerning mainly the true description of the related objects or states of affairs, Solution is an intellectual, emotional, volitional and spiritual characteristics of some human beings in relation not only to the true knowledge of the objects but also to the true knowledge of the self, and to the valuable words and virtuous actions Knowledge has been a branch of philosophy since the 17th century; Lefstein, 2010 and epistemology deals with such issues as the nature and derivation of knowledge, the scope of knowledge, and the reliability of claims to knowledge. Finally demonstrates the idea of dialogue among civilizations and idea of league of civilizations to overcome the global financial crises from the arguments given by political leaders as well as great thinkers of civilizations studies. This study can be helpful for practitioners in refining their way of thinking about Knowledge.

Abstract: Neuromuscular disorders term refers to all diseases that affect nerves and muscles. Amyotrophic Lateral Sclerosis (ALS, also called Lou Gehrig’s disease) is one of the most common neuromuscular diseases worldwide. Individuals with ALS may suffer from voluntary muscles (legs and arms muscles) weakness and difficulty in swallowing or breathing. Recently, mobile technology is used in the health sector to improve the quality of and access to health care. Mobile health applications help patients to monitor their treatments when it becomes difficult to obtain attention from health workers regularly. EMGNeu is a mobile health application that aims to help ALS patients to discover their disease once it occurs based on EMG signal. That is by focusing on new trends of integrating artificial intelligence methodologies as support vector machines into mobile telemedicine solutions. EMGNeu doesn't only help patients to track their neuromuscular conditions but it also helps their physician as well. Physicians are able to track their patients by receiving alerts when the disease is discovered and sending recommendations to the patients to help them monitoring their emergency case until they could obtain medical help.

Abstract: Plants as all alive suffer from impacts of natural or anthropogenic stress factors. Creation of wireless smart biosensors and wireless sensor networks on their base for express-diagnostic of plant state on large territories under impact of stresses of different origin provides to apply managerial measures in time to decrease the negative impact of natural and anthropogenic load on the state of agricultural lands and green plantations of megalopolis, national preserves, woodlands and parklands. The applications of wireless technologies in agriculture and ecological monitoring are considered. The main aim of the multilevel sensor network is real-time data acquisition of state of plants on large territories, on-line data processing and timely decision making according to specified criteria. Multilevel sensor network has two levels. The low level is intended for plant state data acquisition and consists of several wireless sensor networks as primary data acquisition systems. The high level of multilevel sensor network works in "cloud" environment and the main purpose of this level is data storage, data analysis and managerial decision making. The main work purpose is development of low-cost wireless smart biosensors for express-diagnostics of common state of plants and creating the proper software and methodical support for integration of these wireless biosensors into wireless sensor network and multilevel sensor network for express-diagnostics of plant state on large territories, what make possible to spread the application of new information and communication technologies to industrial agriculture, ecological monitoring and environmental protection.

Abstract: We study mobile communication of the ad hoc networks. Ad hoc networks are complex distributed systems that consist of wireless mobile or static nodes that can freely and dynamically self-organize Namicheishvili et al, 2011. The main finding is the performance of Multicast Routing protocol with Dynamic Core (MRDC) multicast tree in a variety of mobility and communication scenarios. We focused on control plan of MRDC. Because of this, in this paper the performance means the efficiency and robustness of multicast tree. Mode selection of forwarding plan is disabled and multicast routers broadcast multicast packets. The aim of the simulation is to evaluate the robustness and efficiency of multicast tree. The performance analysis contains of two goals: to select MRDC key parameters (e.g. period of multicast tree refresh and threshold for average queue length) and to analyze performance in different traffic loads and mobility pattern. The performance analysis is further divided into two parts: multicast tree analysis and protocol comparison.

Abstract: Image de-noising is the elimination of noise from digital images where noise is any undesired information that contaminates an image. De-nosing is achieved through various filtering techniques that not only enhance the image but also keeps all its important details. Filters are categorized into linear (Geometric mean and Harmonic mean filters) and non-linear (midpoint, alpha-trimmed and adaptive local noise reduction filter) techniques. This paper presents applying Gaussian de-noising techniques or algorithms in spatial domain for medical images. Actually, five de-noising techniques are developed on gray scale medical images corrupted by additive Gaussian noise with mean = 0, variance = 1000. In addition, the paper analyzes the de-nosing techniques in terms of MSE (Mean Square Error), PSNR (Peak Signal to Noise Ratio) for image quality assessment and time complexity for performance assessment. The results showed that the de-nosing technique named Harmonic filter was the best from PSNR prospective and the de-nosing technique named Geometric mean filter was the best form time prospective.

Abstract: Organizations are becoming more and more dependent on computers in their day to day activities. Employees spend hours daily interacting with various software that is needed to finish their work. This human computer interaction (HCI) may induce stress for various reasons such as bad user interface design, slow responses from the software, and much more. Stress will affect the employee’s total performance and productivity, which will have a negative impact on their teams and organization. Our purpose is to have an integrated mechanism that will detect stress during HCI. The tool will be a starting point for providing a solution that aims to reduce stress in the HCI aspects at organizations. This study investigates the usage of two bio signals (EEG, ECG,) for the detection of stress during HCI.

Abstract: The problem of forming an optimal portfolio of securities under uncertainty was considered. The main objective of portfolio investment is to improve the investment environment, giving securities such investment characteristics that are only possible in their combination. Careful processing and accounting of investment risks have become an integral and important part of the success of each company. However, the global market crisis of recent years has shown that the existing theory of optimization of investment portfolios and forecasting stock indices themselves exhausted and needed overhaul of the basic theory of portfolio management. Therefore the fuzzy sets theory was used for getting an optimal portfolio. The direct problem with the use of triangular, bell-shaped and Gaussian membership functions and dual problem by using the fuzzy sets theory were considered in this work. In direct task we define structure of a portfolio which will provide the maximum profitableness at the set risk level. In dual task we define structure of a portfolio which will provide the minimum risk level at the set level of critical profitableness. The input data for the optimization system were predicted by using the Fuzzy Group Method of Data Handling (FGMDH). The optimal portfolios for asset were determined. The comparative analysis of optimal portfolio obtained by using of different membership functions was fulfilled. Investment portfolio optimization system is an effective tool for the operational management of portfolio investments. This is an opportunity to carry out scientific and reasonable management of their investment portfolio with the ability to reject the planned loss of possession or overvalued risky assets, which increases business efficiency and maximize gain on the stock market.

Abstract: The purpose of this article is to initiate a research in one of the main parts of time management, which is an extremely useful activity that implies an effective use of personal time. Namely, we propose to include optimal scheduling algorithms into time management techniques. Specifically, we consider a time management system including two persons, one of which is a supervisor. In scheduling theory, such a processing system may be modeled as a two-machine flowshop with the objective of minimizing the makespan. Due to a specificity of the scheduling process for a person, it is assumed that the job processing times may be uncertain before scheduling. Moreover, for time management, it is necessary to consider on-line scheduling along with usual off-line scheduling for a set of jobs to be completed by a person during a day.

Abstract: A synthesis of methodologies of foresight and sustainable development is offered for problem solution on the development of the formalization of vector’s indicators of sustainable development in different directions. The approach to the building of indicators of the environmental component of sustainable development vector at the stage of the data compilation to a single indicator is proposed. The procedure for the formation of the indicator using common hierarchical structure was proposed. It allows considering, evaluating, and forecasting each indicator, which is built. This result is achieved by the recovery of the main functional dependencies on the basis of the characteristics of the groups defined by discrete samples. In the result the functional dependencies of these indicators from a number of parameters that affect them are obtained. The practical implementation of the approach based on the use of the proposed algorithm was realized. The indicators were taken on data of state statistics and the statistics that are offered directly on the website of statistics of the Crimean region.
