In the development of models of reliability of fault-tolerant systems, one of the tendencies for raising the degree of their sufficiency is accounting real distribution laws for duration of procedures and time intervals between events of processes. Accounting real distribution laws in the model is possible with Erlang phase method. Implementation of this approach implies creation of model of reliability...
The work proposes an approach and architecture for a tool of automated testing firmware functions' worst-case execution time. The proposed approach and architecture are universal for any firmware created in Keil uVision IDE in C language using CMSIS-RTOS RTX.
The development of states-transitions model is an important stage in the technology of the development of the discrete-continuous stochastic models of fault-tolerant systems. There is a known method of developing the states-transitions model, which is based on an algorithm of constructing the state-transitions models out of so-called “structural-automaton model”. This method is implemented in a software...
The mathematical models and methods for thermal analysis of two typical constructions of microelectronics systems have been presented in this chapter. The 3D thermal model of hybrid circuits in the form of multilayer structure with flat and add-on heat sources have been developed. The combination of numerical and analytical methods for investigation of this model has been used which allows to solve...
Development of states diagram model of the research object is a stage in the technology of building discrete-continuous stochastic behavior models. There is a known method of building states diagram using structural-automaton model. Unlike other known methods, it allows to automate the development of states diagram after changes in research parameters. The most important part in this method is the...
In this work was consided the method of image representing on the principle of the polar coordinate system to optimize the process of storage and transformation on the plane.
The non-linear model of the transient heat exchange process in a flat plate, heat from which is dissipated due to evaporation, has been built. The numerical solution of the non-linear model problem has been obtained by the Newton-Kantorovych method. Changes of temperature field in time and evaporation influence on the heat dissipation process have been investigated.
This paper describes the client-server architecture of graphical postprocessor for scientific visualization of temperature distribution issues in microelectronic chips and the overheat visualization algorithm that generates three-dimensional model on which critical temperature regions are noticeable.
The new mathematical model introducing a quality index of the software project size determined at the testing stage for the software reliability estimation and prediction is suggested.
