This paper focuses on a Natural Language Processing (NLP) system and Image Recognition using python and Raspberry Pi. NLP Engines are widely used in various tech domains such as surveillance, defense, advanced medical diagnosis, virtual assistant and machine learning. Open CV based image processing algorithm is applied for image recognition, facial comparison, pattern recognition, security system, object detection and deep learning. In this proposed system to implement intelligent QAS system, NLP and Image processing are integrated.
The presented article represents the rudimentary-shaped effective 1 × 2 MIMO antenna structure. The five variation types in the ground region shape are analyzed. The structure's total dimensions are 40 × 36 × 1.6 mm 3 . For efficiently manufacturing, the low-profile substrate FR4 is employed, and the reflectance response of a simulated and modelled design is compared. The placement of two T-shaped slits in the ground area aids in achieving a wider bandwidth, multiband response, excellent Gain, and directivity. Overall, the PW:4 has a minimum reflectance coefficient of −34.54 dB, a broad bandwidth of 3.38 GHz, a peak gain of 13.02 dB, maximum narrow band isolation of 62 dB, and a maximum normalized directivity of 156°. The Envelop Correlation Coefficient, Channel Capacity Loss, Total Active Reflection Coefficient, and Diversity Gain for MIMO design are also examined. These findings indicate the provided design's behavior as per the standard requirements.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
