This paper presents BER, FER performance comparison, especially on PHY mode of IEEE 802.15.4g and IEEE 802.11 under AWGN channel through a simulation, which is communication method using identical frequency bandwidth in M2M environment. This considers suitable communication method of required parameter. It is advantageous that FSK method is used in situations where the system require low complexity and inexpensive structure. And OFDM method is considered for system performance. Further, when the high throughput and various traffic characteristics of the system are required, it can be considered that the method of IEEE 802.11 OFDM PHY mode is used

Forest fire, if not detected early enough, can cause great damage. In order to reduce it, it is important to detect fire as soon as possible and take actions to it. In this paper we propose a new image detection method for identifying fire in videos. The method analyzes the frame-to-frame change in given features of potential fire regions. These features are color, boundary roughness and skewness of the estimated fire regions. Because of flickering and random characteristics of fire, these are powerful discriminants. Using these statistical features, the results are combined according to the Bayes classifier to achieve a decision (i.e. fire happens, fire does not happen). Experiments illustrated the applicability of the method.

In this paper, we have developed 8.0″ WVGA grade's automotive application with advanced fringe-field switching (conventional AFFS+) under wide temperature(−40∼105 °C). Besides, we have achieved high contrast ratio(> 1000:1), fast response time(≤ 25ms), excellent color characteristics and wide viewing angle. We propose new AFFS+ design for high image quality Display.
