Optimal Abrasive Jet Machining Parameters for Glass Fiber Reinforced Plastics
Abstract: Abrasive jet machining (AJM) is a best choice for processing of glass fiber reinforced plastics (GFRP). Inherent to the nonlinear behavior of performance characteristics during repeated experiments are inevitable variations, attributed to measurement errors and unknown influencing input variables. This study employs the Taguchi method with an orthogonal array to systematically identify optimal input variables through a limited number of experiments. The paper introduces a direct and reliable Taguchi-based multi-objective …

Deploying Fuzzy Logic for Self-Tuning Regulator Design for Motion Control in Modern Electrical Machines
Abstract: Modern electrical machines require sophisticated motion control systems capable of adapting to varying operating conditions, load disturbances, and parameter uncertainties. Traditional self-tuning regulators (STR) based on classical control theory often struggle with nonlinearities, time-varying dynamics, and complex operational environments characteristic of contemporary electric drives. This article presents a comprehensive framework for deploying fuzzy logic in self-tuning regulator design to address these challenges in motion control applications. Fuzzy logic controllers leverage …

Dielectric Polymer Based Tunable Bandpass Filter for RF MEMS Applications
Abstract: In this paper, we report on the design, modeling, and analysis of a tunable bandpass filter implemented in a coplanar waveguide (CPW) configuration, where a distributed MEMS transmission line (DMTL) is integrated with dielectric polymer layers to achieve dynamic frequency and bandwidth reconfigurability. The proposed filter architecture leverages the tunable dielectric response of polymer films, enabling precise control of the center frequency and passband width under applied electrostatic bias. Comprehensive …

Roll-off Improvement of Open-circuited Stub Bandstop Filter
Abstract: This paper presents an alternative implementation of a shunt open-circuited stub bandstop filter for microwave circuit. By making use of the proposed implementation, a simple and compact bandstop filter with distinct bandstop characteristics is designed at 1.25 cutoff frequency and FBW of 1.2. This paper also focuses on how to increase the roll-off of bandstop filter by increasing the number of the shunt stub. A shunt open-circuited stub is the …

Review on Free Piston Linear Alternator
Abstract: This study presents the development methodology of the Free-Piston Linear Alternator/Generator (FPLG). The FPLG is a free-piston combustion engine with an integrated linear generator. The engine can be used as a range-extending device in an electric vehicle. Unlike conventional internal combustion engines, a free-piston linear engine has no a crankshaft, and thus the pistons move freely in the cylinder. This allows a free-piston linear engine to easily adjust the compression …

Review of Simulation Techniques for Microscopic Mobility of Pedestrian Movement
Abstract: Simulation techniques are very useful for developing models or systems over time torepresent the real-world scenarios. The model represents the key characteristics orbehaviors/functions of the selected physical or abstract system or process. Simulationtechniques are useful when the real system cannot be engaged, because of inaccessibility,or dangerous or is unacceptable to engage or does not exist. Microscopic characteristicsof pedestrian traffic consider speeds, walking directions, distances between pedestrians,relative positions, passing behavior and …
