Consideration of Collision Damage in FPSO Structural Design
Abstract: AbstractA collision event may be catastrophic for an offshore facility or a floating production, storage and offloading unit (FPSO). Depending on the size and speed of the impacting ship, anything from damage to hull rupture, oil pollution, flooding, loss of buoyancy, capsizing, and sinking may occur. Supply vessels and tankers frequently visit the FPSO to transport consumables and chemicals and, consequently, there is a risk of collision between two structures. …

A Note On Design Methodology For Sheet Pile In A River With Large Tidal Variation
Abstract: The stretch of river Ganges from Kolkata to Haldia port experiences high variation of tide and occasionally experiences remarkable phenomena of bore tides which take place under the right hydraulic and astronomical conditions. A tidal bore, consisting of the head-wave of an advancing tide, hemmed in where the estuary narrows suddenly into the river moves rapidly up the river at speeds reaching 10 m/s. Further, the rise of water depth …

Design of Ultra-Low-Power Robust SRAM Cell
Abstract: SRAM is designed to provide an interface with CPU and to replace DRAMs in systems that require very low power consumption. Low power SRAM design is crucial since it takes a large fraction of total power and die area in high-performance processors. An SRAM cell must meet the requirements for the operation in submicron/nano ranges. The scaling of CMOS technology has significant impacts on SRAM cell random fluctuation of electrical …

Simulation of a Wastewater Treatment Plant Designed on a Flow Sheet
Abstract: The residual water results from the alteration of the physicochemical parameters of clean water; so the latter's vocation is lost. The scarcity and importance of this resource requires its immediate recovery by applying the most appropriate corrective procedure. The tertiary wastewater treatment removes traces of organic and inorganic matter. Although effective, this cleaning step is expensive. The simulation of processes helps in the study of the external and internal changes …

Descartes Foundationalism: An Answer to the Skeptics’ or a Way Out?
Abstract: The phenomenon of knowledge is a fundamental issue in epistemology as a main branch of philosophy concerned with knowledge-related problems. Over time, epistemologists attempted to give us or provide clues as to what reality actually is, that is the question of the certainty of knowledge has always been topical in any epistemic enterprise. The search for knowledge becomes more cumbersome when one considers the challenge of the skeptics and sophists …
