摘要

This paper describes the characteristics of the Special Sensor Microwave/Imager (SSM/I) onboard the Defense Meteorological Satellite Program (DMSP), analyzes absorbing, re-emitting and scattering effects of the atmospheric particles (especially cloud particles and rain drops). The inner physical cause of typhoon's representative form on microwave images is revealed. An index of particle size is then induced as such: Symmetrically inverse channel 85H's (85H is an abbreviation for channel 85. 5 GHz in horizontal polarization, see Table 1 in the text.) absorption segment and put it into the extension of the scattering segment. The precipitation index was formed as the average of three elements: normalized 19H, normalized 37H, and inversed normalized 85H. It is approved that the image of particle size index overcomes some shortcomings of the single raw channel, such as: 37H is not sensitive to large rain drops, 85H is not sensitive to mid-size rain drops and can reveal typhoon's spiral structure more clearly.

Nails are the body part which are farthest from the heart and therefore receive oxygen at last. As a result the nails are the first who show the symptoms of a disease in the human body. Fingernails can be easily captured for diagnosis and there are no heavy equipment or no specific conditions required to use nail image for disease diagnosis, like in other tests and scanning processes. Human nails deliver beneficial information about complaints or any nutritive imbalances in the human body depending upon their shape, texture and colour. In human beings, numerous systemic and skin diseases can be easily analyzed through careful examination of nails of both the limbs. A lot of nail illnesses have been found to be primary signs of numerous underlying systemic illnesses. The colour, texture or shape changes in nails are signs of many diseases mainly affecting nails. Considering all these properties of nails a system is proposed that uses digital image processing (DIP) methods for identifying such changes in the human nail to get more precise results and predict numerous diseases effortlessly. With the emerging Internet of Things (IOT) concept the generated report is made available remotely, this will help users to reduce transportation efforts. As the system has to deal with large and private data, the security of data must be ensured. To keep the data confidential, the Blockchain concept which is one of the most emerging concepts in the field of data management is used. The paper contains the implementation of the digital image processing for feature extraction of nail images, usage of IOT (ThingSpeak cloud) for data storage and implementation of Blockchain to keep the system secured and theft free.
