The goal of this project is to perceive and detect gas leakage, gas cylinder drop level, food count and library book history of the student by using gas sensor, weight sensor and RFID (Radio Frequency Identification) approach and to provide complete information and usefulness needed. This proposed system defines the design of RASPBERRY PI based on a security system for use in industries or hostel...
Nowadays the use of electricalequipment in industries and organizations has increased, thus the incidents of electrical shocks also started increasing. A shock can be occurred due to GF (ground fault) and less maintenance of the electrical loads, due to this problem the people are affected by the electric shock. To avoid this problem an advanced method for the protection of human life against the...
We propose a secure cloud storage model that prominently addresses security and storage issues in cloud. The security is achieved by anonymous authentication of the users; where the attributes associated with individual users are hidden from cloud. This helps the cloud users to remain anonymous as well authenticated, for this digital signature based authentication scheme is developed. Also, a decentralized...
Loss of field is one of the incidents that threats synchronous generators and power systems. After the excitation is lost, rotor current decays at a rate determined by the field circuit time constant. The internal generator voltage will decay at the same rate. Then the machine behaves as an asynchronous generator and draws a high quantity of reactive power from the network. The active power output...
This paper presents an indirect field oriented control (IFOC) of five-phase induction motor drive fed by a five-phase inverter using mat lab/simulink. IFOC is an established control method for high dynamic performance AC drives and the control is simple and highly reliable. Three phase induction motors have many well recognized advantages however their applications are limited to lower end of the...
