We propose a new way for computation of local wave number or instantaneous frequency, which is used in adaptive artificial boundary conditions using for nonlinear 1D Schrödinger equation. Computer simulation results, obtained by using of this method, are compared with corresponding results obtained by solving this equation with zero-value boundary condition for enough bigger size of domain and demonstrated the efficiency of proposed method.

Smart-grid-enabled transformers have unique challenges in rural settings. One such challenge is that of effective and reliable communication of data. Communication infrastructure in rural areas is often elementary and transformers should accommodate this. Communication and sensor devices installed on these smart transformers should also be reliable and robust to minimize their required maintenance. In this paper, the development and application of a communication device for deployment on rural distribution smart transformers is presented. The communication device is robust, enables event-based as well as periodic data reporting from the transformer and monitors transformer health. The communication device implements Distributed Network Protocol version 3 (DNP3), Simple Network Monitoring Protocol (SNMP), Hypertext Transfer Protocol (HTTP) and File Transfer Protocol (FTP) for communication purposes.

The purpose of this article is to demonstrate a way of intellectualization of automated information and diagnostic systems using knowledge bases, databases and algorithms for the formalization of procedures in terms of the development of an expert system for marine diesel engines. The aim of this work is to develop an expert system's architecture with data mining tools for solving the problem of technical exploitation of marine diesel engines based on fragmented, unreliable and possibly inaccurate information. The architecture of such expert system allows moving from normal monitoring to "information monitoring" in the specialized intelligent human-machine systems. Application of data mining technology allows optimizing database processing queries that retrieve the required information from the actual data in order to detect important patterns. An approach based on data mining and fuzzy logic in the expert system is shown on an example of solving technical exploitation of marine diesel engines problem.

The methodology for the electronic networks optimization was elaborated by means of the optimal control theory approach. In this case the problem of the electronic system design is formulated as a classical problem of functional minimization of the optimal control theory. The minimal time system design algorithm was defined as a controllable dynamic process with an optimal control vector. By this methodology the aim of the system design process with minimal computer time is presented as a transition process of some dynamic system that has the minimal transition time. The optimal position of the control vector switch points was determined as a principal characteristic of the minimal-time algorithm. The Lyapunov function of the optimization process was proposed to define optimal structure of control vector.

The method of a sequential circuit design based on using mixed description of a circuit behavior has been developed by us earlier. The method provides fully delay testability of a combinational part of a sequential circuit. It is oriented to cut down the path lengths of the obtained circuits. In this paper the possibilities of a simplification of combinational parts of the sequential circuits are considered. They are based on using corrected Free BDDs instead of ROBDDs and factorizing monotonous products. Some experimental results are given.

Matrix method for diagnosing functional failures and stuck-at faults in software or hardware units is proposed. It is based on qubit or multi-valued data structures for defining diagnostic information, which allows significantly reducing the computational complexity of the simulation and diagnosis due to the introduction of parallel logical operations on the matrix data. The qubit method for fault-free simulating digital units with the possibility of online repair of digital system components is presented. It is characterized by significantly improved performance due to addressed processing procedure of the functional primitives, defined by qubit vectors of output states.

In this paper we propose a further development of compaction procedure of based on decomposition tree. The goal of the development is to simplify a decomposition tree, in other words to reduce the number Local Don't Care sets (LDCs). A simplification is achieved due to an introduction of iteration step in the process of decomposition tree creation.
