Design and Development of an Optical Fiber pH Sensor using an Artificial Neural Network
Abstract: This project presents the development and design of an artificial neural network (ANN) in signal processing of optical fiber pH sensor. The pH sensor has bromophenol blue (BPB) solution as the indicator which is immobilized in a sol-gel thin film as a sensing material. The indicator shows change in color as pH of the solution changes and the spectra of these changes are calibrated to find the pH value. The …

An Overview on Microwave Remote Sensing for Earth Observation
Abstract: To understand the Earth from space, one must look beyond the visible eye. While optical satellites rely on the Sun’s reflection much like the human eye they are frequently blinded by the curtain of cloud cover, smoke, or the dark veil of night. To bypass these limitations, we turn to Microwave Satellite Sensing. By utilizing electromagnetic waves with wavelengths ranging from 1 millimeter to 1 meter, we can see through …

Nanotechnology and its Potential in the Future
Abstract: Nanotechnology is the study of extremely small structures. The prefix “Nano” is derived from the Greek word “nanos” meaning ‘DWARF’ (Small). The beauty of nanotechnology is its ability to make things smaller, so they have more impact on our lives. Nanotechnology deals with materials in the size of 0.1 to 100 nm. One nanometer is one billionth of a meter (10–9 m or 10–7 cm), about 100 thousand times smaller …
