Abstract -
The furnace at the UPT Integrated Laboratory at the University of Diponegoro has automatic temperature control and is equipped with a control display but cant be monitored in a separate room. In this research, a web-based control and monitoring system was built on an electric tube furnace, so that the operator could control and monitor the plant through a Human Machine Interface (HMI). HMI could be accessed from a separate room. The system was built using an STM32F103C8T6 microcontroller and ENC28J60 Ethernet module. As a result, the HMI can carry out supervision and control properly. Data transmission to the server has an average interval time of 12.5 seconds, reading data from the server has an average interval time of 9.2 seconds, and the HMI response to new data entered is 0.8589 seconds.

Abstract -
The paper presents a framework for the automation of testing of component-based systems and embedded systems by considering test purposes. We deal with the component-based systems from communication point of view. Hence, only the external behavior of the components at the interaction points can be observed. For test generation, we adapt a generic FSM-based method by including test purposes to optimize the amount of the generated test sequences for practicability reasons. These methods have been generically since decades successfully used for testing both hardware and software including protocols and communicating systems.

Abstract -
One of the most important decisions for regulatory body is to give a license for increasing or decreasing reactor power or reactor operation. Model predictive control proves its reliability to help the operator and regulatory body to ensure NPP operational safety. This paper introduces a modified model predictive control based on genetic algorithm. It relies on decreasing both the input cost and the difference between real output and optimum output by using a minimizing factor. The results show a reduction in overshoot and settling time of NPP systems parameters, which improve the NPP safety and stability.
