An image captured by a web camera contains stationary and nonstationary noise patterns. These noise patterns are of three types i.e. Fixed Pattern Noise (FPN), Interactive Nose (IN) and Temporal Noise (TN). TN is an independent noise pattern and needs an ... see more

 In modern electro-optical systems, infra-red (IR) imaging system is an essential sensor used for day and night surveillance. In recent years, advancements in IR sensor technology resulted the detectors having smaller pitch, better thermal sensitivit... see more

La medición de descargas parciales (DP) se sustenta en la detección y filtraje de pulsos de corriente que aparecen en una banda de frecuencia que abarca desde los kilohertzios hasta los gigahertzios, por tal motivo los detectores de descargas parciales (D... see more

In this paper, we analyze the noise quantization effects in coefficients of discrete wavelet transform (DWT) filter banks for image processing. We propose the implementation of the DWT method, making it possible to determine the effective bit-width of the... see more

In this paper, electrooptical evaluation techniques of image intensifier tubes for some of the important parameters like resolving power, absolute spectral responses of photocathode,  spectral response of phosphor screen, modulation transfer function... see more

The security of most cryptographic systems depends on key generation using a nondeterministic RNG. PRNG generates a random numbers with repeatable patterns over a period of time and can be predicted if the initial conditions and algorithms are known. TRNG... see more

Analysis of survey data is a matter of significant concern as it plays a key role in organizational and behavioral research. Quantitative survey data possesses several distinct characteristics i.e., fixed small range of ordinal values, importance of respo... see more

This study reviewed the pattern of malocclusion among orthodontic patients in East Coast of Sabah and the type of treatment indicated for the patients. A total of 138 pre-treatment orthodontic records of patients who attended the orthodontic consultation ... see more

Introduction: Fixed dose combinations (FDC) enhance the efficacy of individual drugs, decrease the chances of drug resistance, improve patient compliance and also decrease the pill burden on the patients. Irrational prescribing of FDCs is a majo... see more
