The diversity and dynamics of Lactobacillus populations in traditional raw milk Camembert cheese were monitored throughout the manufacturing process in 3 dairies. Culture-dependent analysis was carried out on isolates grown on acidified de Man - Rogosa - Sharpe agar and Lactobacillus anaerobic de Man Rogosa Sharpe agar supplemented with vancomycin and bromocresol green media. The isolates were ...

Currently, the coding efficacy of cutting-edge video standard H.266/VVC surpasses that 3D-HEVC (3D-High Efficiency Video Coding), but existing VVC (Versatile Coding) low-complexity algorithm is mainly optimized for 2D and cannot fully utilize characteristics depth map itself. Based on this, we propose a fast decision employing CNN (Convolutional Neural Network)-LNN (Lightweight Network) model t...

Blockchain (BC) and Machine learning (ML) technologies have been investigated for potential applications in medicine with reasonable success to date. On the other hand, as accurate early diagnosis of skin lesion classification is essential gradually increase survival rate patient, Deep-Learning (DL) ML were introduced supporting dermatologists overcome these challenges. This study designed a As...

Due to the development of transportation, population growth and industrial activities, air quality has become a major issue in urban areas. Poor leads rising health issues human’s life many ways especially respiratory infections, heart disease, asthma, stroke lung cancer. The contaminated comprises harmful ingredients such as sulfur dioxide (SO2), nitrogen (NO2), particulate matter PM10, PM2.5,...

The newest video compression standard, Versatile Video Coding (VVC), was finalized in July 2020 by the Joint Experts Team (JVET). Its main goal is to reduce bitrate 50% over its predecessor coding High Efficiency (HEVC). Due new advanced tools and features included VVC, it actually provides high performances—for instance, Quad Tree with nested Multi-Type (QTMTT) involved partitioning block. Fur...

In HTTP Adaptive Streaming (HAS), videos are encoded at multiple bitrates and spatial resolutions ( i.e. , representations ) to adapt the heterogeneity of network conditions, device attributes, end-user preferences. Encoding same video segment increases costs for content providers. State-of-the-art multi-encoding schemes improve encoding process by utilizing encoder analysis information from al...

Um método modificado para o cálculo da carga faradaica normalizada (q fN ) é proposto. O método envolve a simulação de um processo de oxidação, por voltametria cíclica, empregando potenciais na região da reação de desprendimento de oxigênio (RDO). Este método é aplicável a espécies orgânicas, cuja oxidação não é manifestada por um pico de oxidação definido em eletrodos de óxidos condutores. A v...

501 Abstract—In the H.264/ AVC video coding standard, the intra-prediction coding with various block sizes offers a considerably high improvement in coding efficiency compared to previous standards. In order to achieve this, H.264/AVC uses the Rate-distortion optimization (RDO) technique to select the best intra-prediction mode for a macroblock, and it brings about the drastic increase of the c...

Besides the rate-distortion (R-D) behavior, in a real-time wireless video communication system, the end-to-end delay would also significantly affect the overall video reception quality. To analyze, control and optimize the R-D behavior under the end-to-end delay constraint, in this paper, we extend the traditional rate-distortion optimization (RDO) for the wireless video communication system an...

As the next generation of video coding standard, High Efficiency Video Coding (HEVC) adopted many useful tools to improve coding efficiency. Sample Adaptive Offset (SAO), is a technique to reduce sample distortion by providing offsets to pixels in in-loop filter. In SAO, pixels in LCU are classified into several categories, then categories and offsets are given based on Rate-Distortion Optimiza...
