In general, R factors of 3 to 5 produced more satisfactory performance with less displacement and drift. The displacement variations between different building heights were consistent at different R factors. This study evaluated how R factors influence

IRJET - An Experimental Investigation of Paver Block by using Coconut Fib...IRJET Journal
This document presents an experimental investigation on using coconut fiber as a partial replacement for cement in paver blocks. Coconut fiber was added at 0.1%, 0.2%, 0.3%, and 0.4% replacement by weight of cement. Paver blocks were cast and tested for compressive strength after 7, 14, and 28 days of curing. The results showed that compressive strength increased with the addition of coconut fiber up to 0.3% replacement, with the highest strength achieved at 0.4% replacement. Literature on previous studies on using natural fibers like coconut fiber in concrete was also reviewed, showing improvements to properties like compressive strength and flexural strength with fiber addition.
IRJET- Studies on the Mechanical Strength Properties of the Metakaolin ConcreteIRJET Journal
This document summarizes a study on the mechanical strength properties of concrete with metakaolin additions. The study tested concrete mixtures with varying replacements of cement with flyash and a constant 5% replacement with metakaolin. Tests were conducted to measure the compressive, tensile, and flexural strength of the hardened concrete mixtures. The results showed that replacing up to 10% of cement with flyash and 5% with metakaolin improved the mechanical strengths compared to normal concrete. However, strengths decreased with flyash replacements over 10%. Therefore, the study concluded that a 10% flyash and 5% metakaolin replacement provided the optimum mechanical properties for the concrete.

STUDY THE EFFECT OF RESPONSE REDUCTION FACTOR ON RC FRAMED STRUCTUREIRJET Journal
This study examines the effect of response reduction factors (R factors) on reinforced concrete (RC) framed structures through nonlinear dynamic analysis. Three RC frame models with varying heights (4, 8, and 12 stories) were analyzed in ETABS software under different R factors ranging from 1 to 5. The results showed that displacement increased as the R factor decreased, indicating less linear behavior for lower R factors. Drift also decreased proportionally with increasing R factors from 1 to 5. Shear forces in the frames decreased with higher R factors. In general, R factors of 3 to 5 produced more satisfactory performance with less displacement and drift. The displacement variations between different building heights were consistent at different R factors. This study evaluated how R factors influence

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
