Evaluation of Minimum Achievable Probability of Reception of Bogus Message in Computer-aided Troop-control Systems 21_7.pdf

The present article is devoted to investigation of message-processing techniques directed towards considerable decrease of risk of bogus-message reception in computer-aided troop-control systems. The article gives defined criteria for generation of a bogus message at the input of an information receiver on basis of probabilistic graph of state of data-communication system, and a comparative evaluation of probability of reception of a bogus message both in unidirectional data-communication systems with dependent and independent errors and in feedback systems. The article also shows that an important decrease of probability of reception of a bogus message in channels of poor quality is caused by decrease of transfer rate. It proposes a technique allowing evaluating a minimum achievable probability of the reception of a bogus message in the systems with given parameters of reception integrity.

Simulation of Cycle-phasing Systems With Split Seek 21_2.pdf

The article presents a developed simulation model of modified cycle-phasing system with split seek, which allows simulating taking into account a high value of probability and packing of errors, effect of digital-signal slip structure of syncro-groups and ther location in cycle. Taking these facts into account contributed to the increase of adequacy of the simulation model with respect to real systems in case of strong non-stationary noise impact. It also gives and analyses the results of the simulation.

System of Means for Control of Semantics of Design Tasks and Design Solutions 21_8.pdf

The article presents a system of means ensuring the control of semantics used and materialized in design tasks thanks to operational comparison with reality whish underlines a project of computer-aided system. The control is performed in a version whish is called predicate and ontological control of design-task statement and design-solutions definition. The potential of the technique of predicate and ontological control contributes to detection of semantic errors, control of design process as well as development of project ontology and reference natural and professional language which should be used by developers of computer-aided systems. The technique of predicate and ontological control is implemented by means of software (C#, .Net 3.5, .Net Remouting) in the form of a set of facilities embedded in tool environment of modeling WIQA [1] within a system of extensions (plug-in) which serves solution of logical and linguistic tasks in design of computer-aided systems.

Pseudocode Programming of Interface Prototypes in Design of Computer-aided Systems 21_12.pdf

The article offers and describes a system of tools for pseudocode programming of interface prototypes in design of computeraided systems. The specific characters and positives of the system determines the following: representation of typical interface solutions as precedents whose base is open for access from any workstation per sample of expert systems; possibility of generation of operational assemblies from standard interface solutions thanks to pseudo-programming bindings and conversion into a source code in C# language for subsequent dynamic compilation and checks of created interface prototypes in order to detect their compliance to conceptions and norms. The system of tools can be accessed from any workstation of corporate network as a special-purpose subsystem embedded into the tool WIQA.Net. The last one contributes to collaborative conceptual design of computer-aided systems.
