Skin cancer is the most common of all cancers. About 35 million cases of skin cancer are diagnosed every year. Malignant melanoma is a dangerous type of skin cancer and it is difficult to treat. Early diagnosis and treatment can increase the survival rate from melanoma. However, the therapeutic treatment is the main option but still it is not feasible for most of the cases. The conventional method of drug release may cause damage to the normal cells present near the abnormal cells due to improper dosage of drug. In order to reduce the impact of drug in normal cells, the flow rate of the drug has to be controlled and the fascination rate of the drug by abnormal cells should be made maximum by targeted drug delivery. The proposed work is to convert the biological system comprising three layers like dermis, subcutaneous tissues, and bones and muscular layers into an equivalent electrical system. The mathematical model for the biological system is determined with its equivalent electrical system, and the tool PSPICE is used to evaluate the fascination and dispersion rate of the drug. In addition to evaluation of fascination and dispersion rate using PSPICE, the fascination rate of drug is measured individually for the three layers as well as for the combination of first two layers (dermis and subcutaneous layers) and for all the three layers using MATLAB. The comparison of the fascination and dispersion rates is done for all the three layers and the same has been analyzed by incorporating a conventional proportional-integral-derivative controller to minimize the dispersion rate.

ABSTRACT:The project is about finding a real time solution for the problems caused by the chalk pieces used in the class room. To overcome the problems that are faced daily by the students and faculty, the project entitled 'Real Time Automatic Blackboard Eraser using Embedded System' has been suggested to automatically erase the blackboard. DC motors of three different types are used for the movement of the instrument. The instrument moves forward and backward erasing the board and collecting the dust automatically from the erasing material due to the rotation of the roller. These processes are automated using PIC16F877A microcontroller. Thus the device avoids the dust flow in the environment and thereby providing good solution for the problems faced by the student, faculty and other electronic equipments that are used inside the class room in a cost effective and time efficient way.
