Performance of Some Modified Ordinary Ridge Regression Estimators
Abstract: In multiple linear regressions, if the data suffer from severe multicollinearity, then the ordinary least squares (OLS) method become more sensitive to it, and in such a case OLS could yield wrong sign for some of the regression coefficients. Therefore, when such a situation arises, we could use one of the biased regression methods viz., ridge regression, principal component regression, and so on, as an alternative method to OLS. This …

Lignin-modified bitumen: Exploring characteristics and performance
Abstract: The surge in crude oil prices has sparked interest in finding efficient and cost-effective alternatives to bitumen, a binder used in road pavement. Bitumen, derived from crude oil distillation or natural deposits, is primarily utilized in pavement grade bitumen, accounting for 83% of its usage. However, traditional hot mix asphalt, which relies heavily on bitumen, emits significant amounts of CO2, CH4, and N2O, contributing to environmental concerns. To address these …

Winding Modification and Analysis of LVDT
Abstract: The LVDT (Linear Variable Differential Transformer) typically uses step-winding mode because it has an advantage such as simple construction and fewer layers of winding. The LVDT converts a location or linear movement from a reference standard (zero or null point) impulse with direction and distance information into a proportionate electrical field using the phase and amplitude components. To produce the output in full stroke, the core’s length must be more …

An Efficient Counter Using Modified Upper and Lower SVL Techniques and TSPCL
Abstract: Low power VLSI has emerged as the fundamental building block of the modern electronic era. This leads to a substantial paradigm shift where both power dissipation, performance and area of utmost importance. In the earlier time of fabrication, power dissipation was mainly neglected due to low device density and low operating frequency needed for computation. But in modern technological era, the need for high device density, higher operating frequency, proliferation …

Tribological Assessment of Chemically Modified Jatropha Curcas Oil Developed by Addition of Graphite Nanoparticles for Biolubricant Applications
Abstract: As an alternative to petroleum-based lubricants, environmentally friendly bio-based lubricants are gaining popularity in the lubrication industry. A sustainable bio-based lubricant, Jatropha Curcas Oil (JCO) incorporates nanoparticles as additives. Nevertheless, this oil cannot be used directly as a biolubricant due to its low oxidative stability. By redesigning the oil's molecular structure through chemical modification, this restriction can be overcome. Epoxidation and oxirane ringopening were the two steps used in this …
