Actual problems of the organization of unit testing of classes
Page:134-142
Release: 2014-1 (4)
Keywords: unit testing, refactoring, low coupling, dependency injection, test double, constructor, inversion of control container
Annotation: This work is devoted to description and the analysis of some problems of development of unit tests which are connected with shortcomings of a tested code. Distinguishing attainment sui-tability to unit testing and obtaining short and clear unit tests, the material of work concentrates on the description of design decisions which lead to emergence of unit tests bulky and difficult for reading. Symptoms and signs of such decisions in a tested code of the program are analyzed.
Overview of two-layer neural network in summerdresses analog-to-digital Converter
Page:122-124
Release: 2014-2 (5)
Keywords: analog-to-digital converter, self-routing, neural network, fault-tolerance
Annotation: The paper deals with upgraded neural network scheme of self-routing analog-to-digital converter. The analysis of the results of two-layer and three-layer neural network is produced and perspectives of self-routing analog-to-digital converter based on neural network are discussed/
Solutions for bin cutting & packaging problem with a constructive and neural network approach
Page:142-149
Release: 2014-1 (4)
Keywords: cutting tasks packaging optimization problems , NP- hard combinatorial optimization problems
Annotation: Formulation of the problem is presented n- dimensional packaging (n = 1, 2 , 3). A description of the method of planes for solving the three-dimensional packaging. Shows the composition of this method for two-dimensional packing problem. To determine the lower limits of problem solving cutting-packing machine used neural networks. Highly efficient algorithms for solving two- and three-dimensional cutting-packing , allowing to quickly build a nesting layout with a coefficient of cutting an average of 85%. The reliability of the results is confirmed by a comparative analysis of the dissertation of the existing approaches to solving the problem and the results of experimental data.
UVM Express is a simplified method of implementation UVM
Page:124-128
Release: 2014-2 (5)
Keywords: SystemVerilog, universal verification methodology (UVM), testbench, functional coverage.
Annotation: UVM is an innovative methodology of functional verification allowing to standardize, simplify and speed up the verification process. However its full implementing takes a significant amount of time. This is what prevents its wider use. This article describes a step-by-step methodology of implementing the UVM which produces value since the first step.
