Evaluation of a retinal image is widely employed to help doctors diagnose many diseases, such as diabetes or hypertension. From acquisition process, retinal images often have low grey level contrast and dynamic range. This paper proposes indices of fuzziness for solving the problems of retinal image enhancement. Histogram of the retinal image is stretched by estimating the optimal parameters of the...
This paper addresses a technique to solve the problem of accumulated heat transfer in solenoid coil of the solenoid valve controlling hydraulic damper by using the switching technique with low frequency. This new method can result in saving the energy loss in solenoid coil. In addition, this technique aims to solve the fundamental problem by reducing direct heat transfer in solenoid coil of the solenoid...
Infrared thermo graphic detector for non-contact temperature measurement is used in this project. Infrared thermometers will give an accurate temperature measurement if the emissivity of the thermometer is adjusted to fit with the emissivity of the measured material. Therefore, to use the infrared to measure the temperature of electrical arch furnaces (EAF) transformer at steel industry, the optimal...
This paper is to mention to the case study of protecting gas turbine trip from damper closing failure and heat recovery steam generator (HRSG) trip from solenoid coil of hydraulic damper burnt. The prevent maintenance method on the most frequent events that trip the gas turbine and HRSG and how to protect the recurrence is also described
