Recovery of Iron Values from Iron Ore Slimes using Reagents
Abstract: Mining wastes include waste generated during the extraction, beneficiation or processing of minerals like iron ore fines, slimes and tailings. Approximately 10–20% of the raw material is discarded as slimes in to slime ponds/tailing dams. Recovery of iron values from slimes result in economic benefit by utilization of waste as a resource and minimizes the threat to the environment. The iron ore slime is generally considered as waste due to …

A Survey of Queuing and Scheduling Mechanism of Input-queued Switches
Abstract: ABSTRACTHigh-speed routers play an important role in the Internet. A main hindrance to high-speed router design is its switch architecture. It concerns with how packets are moved from switch input ports to output ports. The switch architecture can be classified as Output-Queued and Input-Queued switches. It is well known that Output-Queued switches can achieve optimal delay-throughput performance. Output-queued switches are generally impractical for high-speed implementation because of high speed needed …

A Comparative Study of Timed Up and Go Test and Tinetti Performance Oriented Mobility Assessment in Predicting Falls in Hemiparetic Stroke Patients
Abstract: Hemiparesis following stroke is the most frequent cause of adult disability. Falls in stroke survivors are a consequence of stroke related locomotor deficits or balance deficits or gait disturbances. Falls are common following stroke but knowledge about predicting future fallers is lacking. The purpose of this study was to compare Timed Up and Go test (TUG) scores and Performance Oriented Mobility Assessment (POMA) scores for predicting falls in Hemiparetic patients …

Analytical Technique Optimization and ICH-Directed Verification of a Reverse Phase HPLC Approach for Quantification of Bupropion Hydrochloride
Abstract: This method was developed for retention time, peak resolution and baseline response using Bupropion Hydrochloride under optimized conditions as validation. The method resulted in two well separated, well defined peaks, a minor peak at 7.5 minutes 12 mV and a main peak at 11.52 minutes 150 mV. At the same time, the baseline has remained stable during the chromatographic run and the fluctuations of noise are very small (0.5 ± …

Fractal-Entropy Guided Adaptive Signal Reconstruction for Non-Stationary Biomedical and Communication Systems
Abstract: This paper presents a novel Fractal-Entropy Guided Adaptive Signal Reconstruction (FEG- ASR) framework designed for accurate processing of non-stationary signals in biomedical and communication systems. The proposed approach integrates fractal dimension analysis with entropy- based feature evaluation to capture the intrinsic complexity and irregularity of time-varying signals. By dynamically adapting reconstruction parameters based on fractal-entropy measures, the method effectively separates noise from meaningful signal components while preserving critical information.
