There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.

Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

Pressure gauge calibration refers to comparing the standard and test gauge to determine the error percentage. The reading accuracy of the analog dial pressure gauge is found in the conventional method through manual calculations and then tabulating the values in the calibration certificate. The present study is undertaken to increase the accuracy level of the analog dial pressure gauges. A new automated computer-based method is proposed to calibrate the meters more accurately than the conventional method. The indicated value of the pressure gauge is obtained through the angular position of the pointer and the error value is identified by comparing both standard and test gauge values. In this work, Red, Green, Blue (RGB) images of standard and test pressure gauges are acquired through a high-definition camera. After the image processing operations, the pointer orientation of the indicatoris identified, and the indicated values are calculated. The computer-vision-based automatic calibration system is applied in a 0–100-psi (0–689.476 kPa) analog dial pressure gauge, and three trials were performed to determine the accuracy. The computer vision technique improved accuracy, varying from 97 % to 98 % compared with the conventional manual observation method. The observed results have improved repeatability and accuracy with the proposed computer-vision-based system.

Energy generation from renewable sources and effective management are two critical challenges for sustainable development. Biofuel Cells (BFCs) provide an effectice solution by combining these two tasks. BFCs are defined by the catalyst used in the fuel cell and can directly generate electricity from biological substances. Various nontoxic chemical fuels, such as glucose, lactate, urate, alcohol, amines, starch, and fructose, can be used in BFCs and have specific components to oxide fuels. Widely available fuel sources and moderate operational conditions make them promise in renewable energy generation, remote device power sources, etc. Enzymatic biofuel cells (EBFCs) use enzymes as a catalyst to oxidize the fuel rather than precious metals. The shortcoming of the EBFCs system leads to integrated miniaturization issues, lower power density, poor operational stability, lower voltage output, lower energy density, inadequate durability, instability in the long-term application, and incomplete fuel oxidation. This necessitates the development of non-enzymatic biofuel cells (NEBFCs). The review paper extensively studies NEBFCs and its various synthetic strategies and catalytic characteristics. This paper reviews the use of nanocomposites as biocatalysts in biofuel cells and the principle of biofuel cells as well as their construction elements. This review briefly presents recent technologies developed to improve the biocatalytic properties, biocompatibility, biodegradability, implantability, and mechanical flexibility of BFCs.
