An efficient cold-mechanical/sonic-assisted extraction technique was developed for extraction of genipin from genipap (Genipa americana) peel. Ultrasound assisted extraction (285 W, 24 kHz) was performed at 5, 10 and 15 °C for 5, 10 and 15 min. After cold-extraction, genipin was separated from pectin and proteins by aid of fungal pectinesterase. The maximum yield of non-cross-linked genipin was...

oils and fats are substances that are important nutritionally and have important role and impact on human health. energy consumption and preservation in respect of food industry and the increase in the world population and search for new sources of oils and fats to full fill the need of the society particulary the nutritional requirements have introduced this research topic. therefore aim of th...

The aim of this work is to present a non-contact video-based method for respiratory rhythm extraction. makes use consumer-grade RGB camera, and it based on computer vision algorithms detect track custom pattern placed the thorax subject. signal extracted by computing changes in position detected through time. has been validated comparing versus one obtained with reference adult population. was ...

Face Recognition is non-intrusive method of identifying individual faces by the feature extraction and classification of faces. Facial feature extraction is one of the most important and attempted problems in computer vision. This paper compares the different facial feature extraction techniques like geometry-based feature extraction (Gabor wavelet transform), appearance based techniques, color...
