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.

Abstract: The problem connected to computation of non-conflict schedule for crossbar switch node is NPcomplete from mathematical point of view. It is the reason for constantly suggested new algorithms for schedule calculations. The problem is that their efficiency has to be checked. The throughput of a “good” algorithm tends monotonically to some boundary. We suggest a procedure for quantitative determination of the convergence toward the boundary, utilizing data from computer simulation. In this paper are presented results of computer simulation for PIM algorithm with a certain model of incoming traffic (Chao model), made by means of CERN grid structure (lxplus.cern.ch). We check the hypothesis that convergence computation depends on the chosen parameter m of the procedure. Checking is made for m=4 and m=3. The obtained data confirm validity of the hypothesis for the chosen values m. As a result we reach a new conclusion: the derived values of the error for the internal variable δ give (an independent) estimation of the simulation errors. Having this in mind we can plan experiments that will give us the required accuracy for the determination of the boundary under the limited computer power available.

Summary: One of the most important properties of telecommunication networks to ensure their effective functioning is survivability. To ensure the survivability of telecommunication networks it’s required to solve a number of scientific and engineering problems at all stages of their life cycle – design, modernization or improvement, operation. Questions of ensurance of survivability of telecommunication networks are becoming more actual due to the intensive development of telecommunications in the past decade. The synthesis problems of survivability systems, evaluation, ensurance and improvement of structural survivability of the systems, as determined by the needs of practice acquired particular actuality today. The aim of this work is to develop a method of ensurance of structural survivability of telecommunication network (TCN), which implements the streaming approach using the proposed index of structural survivability TCN defined lower boundary of structural survivability, providing a guaranteed stable functioning TCN, the achievement of the desired value which is performed by the introduction of structural redundancy (as the property of survivability possess only redundant systems) using the optimization procedure of the sections branches reservation, the choice of which is determined on the basis of maximizing the effectiveness of each stage of the reservation. The optimization of value of the structural survivability of TCN is to achieve its maximum value at the existing restrictions. The method to ensure structural survivability TCN, based on the formation of sets of admissible routes for each service requirements, for which are formed the sets of admissible sections is developed. Are determined the probable values of unaffecting each section, and for each set of sections, which are formed on the basis of the lower boundary of the structural survivability TCN obtained as an average value of probable unaffecting sections. The paper proposes a developed the method of the ensurance of structural survivability of TCN, which is designed for procedural model, which includes the execution of the sequence of steps: 1) formation of the source data, 2) the evaluation of the structural survivability of TCN, 3) the ensurance structural survivability of TCN, 4) the development of solutions for the structural survivability of TCN. For each stage, are formulated the objectives and are determined ways to decide them. For stage 1) the list and the method to present the initial data are determined; for stage 2) are determined ways of forming sets of admissible routes and obtaining for them sets of 166 International Journal "Information Technologies & Knowledge" Volume 8, Number 2, 2014 admissible sections, for which are given methods for calculating the probabilities of unaffecting of each sections and the probabilities of unaffecting of all admissible sections which separate points s and t ( s,t n = 1, , s ≠ t, n – number of network points), is formulated a condition for the lower bound of the required structural survivability of TCN. In stage 3) optimization problem is formulated to ensure the required value of the lower limit of the structural survivability of TCN as a mathematical programming problem, is shown the feasibility of using the gradient method to solve it, a method of calculating the efficiency of each step of the optimization process. Stage 4) is final. At this stage is drawn the conclusion that the obtained solution of the optimization problem to introduce structural redundancy with in sets of limits or provides the required value of the index of structural survivability TCN or provides the procedure of recommendations on: changing the value of the matrix elements of the probability of unaffecting branches of the network which is computed value by solving the problem; the change of classes (priorities) and the "weights" of certain requirements; limiting values of network requirements, the change of defined limit values, the lower boundary of the structural survivability TCN. The proposed method can be used in the case where the sets of admissible routes and admissible sections are the sets of all possible routes and all possible sections in the TCN. An example of implementation of the proposed method to ensure structural survivability of the telecommunications network is made.

Abstract: The article considers the problem of programmable logic device reconfiguration after a failure of logic elements. The task is relevant to areas such as space exploration and important industrial facilities management that use highly reliable fault-tolerant systems. The article considers the failures of logic elements in the configurable logic blocks. For optimal reconfiguration logic modules must be placed on a programmable logic device without using faulty logic elements, while minimizing occupied area, the bond lengths and delays. The first step in solving the problem is to choose compactly located logic elements that will be involved in the implementation of the circuit. Compactness is understood as the minimum amount of information necessary to describe the set of logic elements. This task can not be solved exactly and effectively, but can be approximately solved by using various heuristics, including genetic algorithms. This article describes several well-known approaches to the problem and offers an original two-level coding method for constructing a genetic algorithm that takes into account features of the problem and uses standard genetic operators. The proposed algorithm is implemented in practice in the form of a computer program to compare its performance with some other algorithms. Comparison of different heuristic algorithms in terms of accuracy of the solution and estimated speed of the proposed algorithm are given. One can say that the proposed genetic algorithm works on average longer than other heuristic algorithms, but finds a more accurate solution. This leads to a reduction of reconfiguration time and, thereby, increase availability ratio of the programmable logic device.
