analysis of Heat Sensor with water pump system using cooling fan to reduce the temperature. This project was done to see the operation of heat sensor and how the water pump system and the cooling fan work. This project is divided into two parts namely software and hardware development. Also‚ it includes two circuits that need to be designed and developed‚ specifically analogue and digital part. Hence‚ to prove the circuit works‚ the simulation of the output need to be shown. This heat sensor consists of

However‚ they approached it with the same tried and tested methods of operations‚ and did not want to let go of their focus and success in the film-based market. (E.g. Kodak was first to introduce image sensor‚ the core element of digital camera‚ but did not take advantage of it) • They spent a lot on R&D‚ launching new products but lacked a central vision or effort towards pushing in the digital camera space. - 1986 launched various electronic image

Reliability and Trust in Mobile Ad-hoc NETworks (MANET) are considerable due to their applicability in different situations such as military‚ emergency applications or health care applications. Indeed‚ due to absence of a fixed infrastructure and a central controller‚ providing trust and reliability still is challenge in these networks. Since energy is limited and distributed in MANETs‚ trust and reliability providing (is different from wired systems and it must be reasonable and compatible with

3. PATH LOSS MODELS Path loss models play a vital role in planning of wireless communication systems. They represent a set of mathematical equations and algorithms that are used for radio signal propagation prediction in certain areas. Propagation path loss models are used for calculation of electromagnetic field strength for the purpose of wireless network planning during preliminary deployment. Path loss model describes the signal attenuation from transmitter to receiver antenna as a function of
