From Two to One Index Isomorphism in Optimization Program for Quarterly Disaggregation of Annual Times Series

A problem of minimization arises when a statistical approach with a cyclical indicator is used to disaggregate an annual economic aggregate quarterly, resulting in a smooth quarterly economic aggregate. There are two quarter and year indices involved in this. When the problem is big, this can make the resolution algorithm less efficient. In order to…

An Innovative 0‐Day Attack against ZigBee: Exploitation and Protection System Analysis

Internet of Things (IoT) networks are a new phenomenon that connects everyday sensors. Because of the devices’ limited functionality and sensitive existence, protection is a critical and primary concern. We present a novel and highly dangerous challenge to IoT networks in this paper. The attack is based on the use of Remote AT Commands, which…

MHD Oscillatory Flow of Jeffrey Fluid in an Indented Artery with Heat Source

We investigated blood flow through an indented artery in this article, assuming blood to be Jeffrey fluid. The impact of heat transfer on the flow profile of Jeffrey fluid in an indented artery is investigated in this analysis. The governing equations are also converted into coupled Bessel differential equations and solved analytically. The effects of…

A Simple Mathematical Model of Exudative Retinal Detachment

Exudative retinal detachment is caused by a lack of understanding of the conditions that cause it, which makes surgery less effective. The detachment is heavily influenced by fluid dynamical effects. To investigate the interaction between the fluid flow and the detached retina, a simple mathematical model for exudative retinal detachment was created, in which the…

Advanced Study on Cyclic Codes Associated to Muffin Ideals over Quaternion Integer Ring ((-1,-1)/z_p )

In this paper, we construct cyclic codes associated with Muffin ideals over quaternion integer rings- where zp is the finite field integers modulo odd prime p. We also find a generator matrix in standard form for These cyclic codes are a good example of this. The Mannheim distance of these cyclic codes is also determined. We’d…

Utilization of Eight-Variable Karnaugh Maps in the Digital Design of n-bit Comparators

An n-bit comparator is a common combinational circuit that compares two n-bit inputs, Y and Z, and generates three orthonormal outputs: G (indicating that Y is strictly greater than Z), E (indicating that Y and Z are equal or equivalent), and L (indicating that Y and Z are equal or equivalent) (indicating that Y is…

Techniques for Analyzing Capacitated Networks: A Tutorial Review

This chapter examines different methods for examining capacitated networks, with a focus on evaluating performance indicators for realistic systems with fixed channel capacities, such as telecommunication networks, power transmission systems, and commodity pipeline systems. Karnaugh diagrams, capacity-preserving network reduction rules associated with delta-star transformations, and a generalisation of the max-flow min-cut theorem are among the…

Karnaugh-Map Analysis of a Commodity-Supply Multi-State Reliability System

When at least km components are in state m or above for all m such that 1 m j, a multi-state k-out-of-n: G device has a multi-valued success greater than or equal to a certain value j (lying between 1 (the lowest non-zero output level) and M (the highest output level) This paper examines a…

Multicollinearity in Binary Logistic Regression Model

One of the major issues with the binary logistic regression model is that the explanatory variables that are taken into account for the logistic regression model are strongly correlated. Multicollinearity affects confidence intervals and hypothesis tests by causing unstable estimates and inconsistent variances. The aim of this paper was to address some diagnostic metrics for…
