Abstract We have studied the use of wireless interfaces in embedded systems for monitoring and control. Basically, we have developed a wireless interface with the educational use and built the system for smart homes. The systems we have used is the Arduino board with a possibility of remote Android based control.... Read More


Eliminating the Noise Parameters of the Quad Sensor Structure

Emil Iontchev, Rosen Miletiev, Vladimir Bashev and Rumen Yordanov

https://doi.org/10.6025/jisr/2021/12/4/109-115

Abstract In the current work we have assessed the noise parameters of the sensor structure of the linear accelerometers. We did it by comparing the usual scale of the single sensors. We found that the signal processing permits the decreasing of major noise parameters of the quad sensor structure. This process permits the accuracy of the sensors and it also helps... Read More


Reliability Assessment of a Star Structured Electronic System

Nikolay Nikolov, Anton Georgiev and Toncho Papanche

https://doi.org/10.6025/jisr/2021/12/4/116-122

Abstract In this work we have studied the reliability assessment of a star structured complex electronic system. The normal methods to reliability indices selection and reliability requirements determination are presented. Some specific reliability indices and basic dependences valid for reliability assessment of a star structured electronic system are presented and described.... Read More


Embedding Autonomic Structure to Reduce Cost in the Machine-to-machine Communication

Ivaylo Atanasov, Anastas Nikolov and Evelina Pencheva

https://doi.org/10.6025/jisr/2021/12/4/123-129

Abstract In network operations, the Machine-to-Machine application is a big issue and the large amount of diverse connected devices which interact with the environment without human intervention. The process of embedding autonomic features in M2M system will lead to reduce the operational cost. In the work, we have developed a system for autonomous agent for connectivity management of M2M devices. The... Read More
