A human body is controlled by electrical signals and is maintained by the physiological state and function. The bioelectricity for maintaining the physiological function is important and its technology is widely used in the field of electricity and biology, etc. There are the unsolved problems related to a human body. Collaboration is required for solving such problem completely. The areas of studies on the bioelectricity and the electrical safety, and the electrostatics are related closely. The collaboration between different areas and the knowledge published on the online journal will be useful for us to solve some future technology related to the human body.

This study centers on the comparison between the gradient curve of the cox proportional hazard and weibull models. It has two faces, the simulated and the real life data approach. The data used for this research work is on tuberculosis diseases for the year 2011. It was observed from the real life data that the shape parameter of the weibull model does not depend or have effect on the performance of the Cox proportional hazard model. It was also observed that both models perform similarly when the distributional assumptions are not met except when sample size is small and the weibull model out-perform the Cox model when the distributional assumption are met and the shape parameter known.
