Abstract: The new generation displays are loaded with several new features to make these systems more user-friendly. There are several attributes of a display such as resolution, luminance and contrast levels, refresh rate, etc. which decides its rating and application. These systems with the human eye features like adaptive display luminance control (ADLC) under varying ambient luminance conditions add more challenge to design of display systems. The ADLC can be achieved by varying the display luminance according to the ambient luminance level. In this paper, various parameters which are important for adaptive luminance control have beendiscussed. Various types of light sensors, methodology and required parameters have been discussed in detail for realizing the display luminance adaptively while maintaining an adequate contrast ratio in real time.

Abstract: After years of research and development the accuracy of automatic speech recognition (ASR) remains one of the most important research challenges e.g. speaker and language variability, vocabulary size and domain, noise. The design of speech recognition system require careful attentions to the challenges or issue such as various types of speech classes, speech representation, feature extraction techniques, database and performance evaluation. This paper presents a study of basic approaches to speech recognition and their results shows better accuracy. This paper also presents what research has been done around for dealing with the problem of ASR
