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 …

Assessment of Compressive Strength of OPC and PPC-Based Concretes Combined by Ultrasonic Pulse Velocity and Rebound Hammer
Abstract: In this study, non-destructive tests were performed on ordinary Portland cement (OPC) and Portland pozzolana cement (PPC) based concrete specimens, namely the ultrasonic pulse velocity (UPV) and rebound hammer (RN). A relationship is thus established between the NDT values and the compressive strength. A statistical regression analysis was performed between the compressive strength with UPV and RN values to obtain a best-fit relationship and correlation coefficients. To take into account …

Juvenile Sjögren’s Syndrome: Case Report
Abstract: In the early 1900s, Henrik Sjögren and Henri Gougerot were the first to discovery the Sjögren’s syndrome. It is a chronic autoimmune disease affecting lacrimal and salivary glands primarily along with other systemic involvements in variability. However, most reports lacked the report of children. This is ordinary, as the disease is common in women of the 4th–5th decade. The manifestation of the disease may differ in children than in adults. …
