Control and Stabilization of Maglev System Using 2-DOF PID Controller and its Comparative Analysis with Other PID Controller
Abstract: AbstractA Magnetic air suspension or a magnetic levitation has turned out to be a very capable technique in the fast common transport system because of its frictionless motion. Due to open-loop system, the elevation in magnetic air is an extremely unstable system; and hence to stabilise this it desire a controller in order to its stabilization and position-tracing. Because of its nonlinear behaviour, its controller implementation is a tough task. …

Bio Solvent EOR: Performance Assessment of Plant Extracts as Asphaltene Inhibitor
Abstract: Changes in pressure and temperature during oil production and transportation most notably during CO2 injection for enhanced recovery could lead to changes in the oil composition and deposition of asphaltene. Deposition of asphaltene near the wellbore region, production tubing and production facilities could cause severe flow assurance problem. Physical removal of asphaltene is costly and in most cases it is not preferred. A more favorable option is to prevent the …

Leveraging cross-coupled domino logic for low-power, two-port SRAM with resilience to Differential Power Analysis (DPA) attacks
Abstract: Side channel attacks have become a serious threat to embedded and cryptographic systems. These attacks can be deployed by capturing the power consumption traces or electromagnetic radiations from the power and communication channels. SRAM is vulnerable to such attacks. Power consumed by SRAM for various read and write operations can express the information about bits being read from or written into the bit-cells which eventually exposes the instructions and data …
