This paper instantly infers the power consumption in the classrooms. The knowledge about the power wastage is used to suggest the smart classroom in which the operation of the electrical and electronic devices are automated. In this method it is first estimated what are all the devices a classroom consist (i.e.) fan, light. Some existing method had already control this kind of devices using infrared remotes. Though the infrared remotes are used, power wastage due to human negligence is possible. Hence by replacing the infrared remote with wireless sensor effective automation can be achieved in the classroom. The smart classroom system controls automatic ON/OFF of fan and light system based on the presence and absence of the human inside the room and based on the temperatures of the room. The system is developed with the help of ARDUINO board which can be used to control the speed of an electric fan based on the changes in temperature of its surrounding using Thermistor.                              

 In recent years, RFID technology has been widely used in various sectors, such as in-education, transportation, agriculture, animal husbandry, store sales and other sectors. RFID utilization in education is student attendance monitoring system, by using Internet of Things (IoT) and Cloud technology, it will produce a real time attendance monitoring system that can be accessed by various parties, such as lecturer, campus administration and parents. With this monitoring system if there are students who are not present can be immediately discovered and can be taken immediate action and the learning process can run smoothly

In this paper we discussed about natural ordered relation in a totally ordered ternary semiring (T,+,.,,≤) in which(T,.) is semilattice defined as a ≤ b ⟺ a =xyb = xby = bxy; a= xya. And also we characterize different properties of a totally ordered semirings with natural ordered relation..

                                                                In section 2, the required preliminaries are presented. In Section 3, properties of totally ordered ternary semirings with natural ordered relation were discussed

This paper is based on the idea of maintaining maximum utilization and minimum loss of available energy. Sun is the source of all energy on the earth. It is most abundant, inexhaustible and universal source of energy. All other sources of energy draw their strength from the sun. India is blessed with plenty of solar energy because most parts of the country receive bright sunshine throughout the year except a brief monsoon period so this paper is based on solar highway light system. If any of the light is fault message sent to authorized person as well non working solar. To avoid accident intelligent system is implemented high beam and low beam. Power saving is the essential  now a days, so to avoid wastage of power intelligent lighting system is implemented, when vehicle is present it will work with 100%intensity rest of the time 50%. Solar energy is used for this application so solar tracking is implemented to track sun and store energy during day timeThis paper is based on the idea of maintaining maximum utilization and minimum loss of available energy.

Based on the theoretical background given in the previous chapter, we try in this chapter to study the exchange rate policy in Algeria by using a  cointegration analysis.  Unfortunately, we are not going to test the Efficient Markets Hypothesis of the Algerian Dinar. This is simply due to the lack of forward exchange rates. Nevertheless, we are going to look for other aspects of exchange rate in Algeria , mainly the parallel exchange rate. Thus the first part of this chapter examines the situation of exchange rate in Algeria by giving an historical review. Secondly , we will define the main factors behind the development of the parallel exchange rate market that lead to a situation of misalignment. Then, in the third part of this chapter,  we show that the Algerian parallel exchange rate is more efficient that the official rate using a purchasing power parity approach . Section 4 gives the implications and recommendations. Evidence shows that authorities should take into account information provided by the parallel exchange rates in deciding the level of the appropriate official exchange rate.
