Parametric Study of Laser Drilling Process Using Multi Variable Regression Analysis
Abstract: The laser drilling process is an advanced manufacturing technique extensively employed for intricate and high-value components in aerospace, automotive, and electronics industries. Laser drilling technology offers opportunities to meet the contemporary demands of industries using a broad spectrum of engineering materials. However, this process encounters several engineering challenges such as thermal damage, dimensional inaccuracies, and the formation of a recast layer in the drilled components. This study focuses on examining …

Prevalence and Factors Associated with Overweight/Obesity in Public Servants, Tigray, Ethiopia: The Case of Mekelle City
Abstract: Introduction: Noncommunicable diseases (NCDs) remain the major causes of mortality. In Africa and sub-Saharan countries prevalence of NCDs is rising due to many reasons. About 80% of deaths due to NCDs are common in low and middle-income countries including Ethiopia. Overweight and obesity are leading risk factors for a number of chronic NCDs. Objective: The aim of this research was to estimate the magnitude and factors associated with overweight/obesity among …

A summary continuation analysis evaluating the prevalence and predictors of diabetic retinopathy in newly diagnosed type 2 diabetic patients.
Abstract: Context: Diabetic retinopathy (DR), the leading cause of acquired blindness in adults, affects approximately 93 million people globally. It is a serious complication of type 2 diabetes, resulting from prolonged damage to the blood vessels in the retina. Although largely preventable and treatable, DR continues to be the main cause of vision loss among working-age adults and significantly impacts quality of life. While most studies on DR in Nepal have …

Multi-loop Adaptive Internal Model Controller for Two Interacting Conical Tank Process
Abstract: In this paper, an adaptive multi-loop internal model control (IMC) scheme is proposed for nonlinear process. Nonlinear multivariable process is decomposed into linear single input single output process. The interaction effect and illness of each linear region is analyzed by RGA (Relative Gain Array) and singular value decomposition method (SVD). It is a matrix technique used to determine condition number of steady state plant to avoid sensitivity problem which arises …
