Design And Implementation of Anti-Interference Low Power Double-Edge Trigger Flip-Flop Based On C-Element
Abstract: Double-Edge Triggered Flip-Flops (DETFFs) will use a lot more power when there are glitches and interference in the signal input. This work proposes an anti-interference low-power DETFF based on C-elements to efficiently lower the power consumption. This DETFF employs an enhanced C-element, which successfully filters input signal glitches, avoids redundant transitions within the DETFF, and lowers the transistor's charge and discharge frequencies. To lower its latency, the C-element has additionally …

Optimizing Sampling Techniques Using Fuzzy Set Theory: A Comprehensive Approach
Abstract: Sampling is a critical process in statistics, used to estimate population parameters without needing to examine the entire population. Traditional sampling methods, such as simple random sampling, stratified sampling, and cluster sampling, face limitations when applied to complex or heterogeneous populations with imprecise boundaries. These methods often fail to accurately represent populations with overlapping characteristics or missing data, resulting in sampling bias and reduced accuracy. To address these challenges, this …

Modeling Dispersed Count Data: Evaluating the Conway–Maxwell–Poisson Regression with COVID-19 Mortality Data
Abstract: Count data are prevalent in diverse fields such as biology, healthcare, psychology, and marketing, characterized by non-negativity and inherent heteroskedasticity, often exhibiting overdispersion or underdispersion. Traditional Poisson regression, which assumes equal mean and variance, is inadequate for such dispersed data. To address this, various generalized linear models (GLMs) and their extensions, including negative binomial (NB) and Conway–Maxwell–Poisson (CMP) regressions, are utilized. This study evaluates the performance of CMP regression compared …
