Analysis of Hydrodynamic Characteristics of a Squeeze Film in O-Ring Assembly Under the Oscillating Motion
Abstract: In the most of the non-contacting face seals, squeezing occurs in the fluid film between the O-ring surface and the mating surfaces in the gland assembly. Therefore, hydrodynamic characteristics are easily simulated by considering a fluid film between a rubber surface (O-ring surface) and a rigid surface (machined surface). In this paper, effects of surface roughness of rubber block on leakage flow rate and hydrodynamic force developed in fluid film …

The Concept of Asbab-E-wajood (Causes of Being)
Abstract: Aristotle said that we don’t have complete knowledge of a thing until we get hold on its why, which tells its cause. If we consider anything and wanted to know how it exists or what keeps its existence possible, then there arises 4 questions i.e. What is it made of? What made it? What is it; Shape Structure, Arrangements? And what is it for? There are seven factors which combine …

Study of Proximity Points and Fixed Points
Abstract: This paper explores the concepts of proximity points and fixed points, which are fundamental in mathematical analysis and nonlinear functional analysis. Fixed-point theorems play a crucial role in optimization, game theory, differential equations, and dynamic systems. Proximity points, an extension of fixed points, provide a more generalized approach, allowing near-coincidence rather than exact identity. The study discusses classical fixed-point theorems, such as Banach’s contraction principle, Brouwer’s fixed-point theorem, and Schauder’s …
