Numerical solution for laminar unsteady flow about fixed and oscillating cylinders

Computer Assisted Methods in Engineering and Science, 2023
This paper presents a finite-difference solution of the two-dimensional, time dependent incompressible Navier-Stokes equations for laminar flow about fixed and oscillating cylinders placed in an otherwise uniform flow. Using boundary fitted coordinates,

Asymptotic Capacity Bounds for Wireless Networks with Non-Uniform Traffic Patterns [PDF]

IEEE Transactions on Wireless Communications, 2008
We develop bounds on the capacity of wireless multihop networks when the traffic pattern is non-uniform, i.e., not all nodes are the sources and sinks of similar volumes of traffic. Our results are asymptotic, i.e., they hold with probability going to unity as the number of nodes goes to infinity.

Current Tracking Adaptive Control of Brushless DC Motors

International Journal of Adaptive Control and Signal Processing, EarlyView.
In this paper, the current tracking for Brushless Direct Current motors is approached considering uncertainty in the parameters of the motor's model. An adaptive control scheme to compensate electrical parameters uncertainty is proposed without requiring any knowledge of the mechanical parameters.

A NON-UNIFORM BOUND ON GEOMETRIC APPROXIMATION TO THE YULE DISTRIBUTION [PDF]

International Journal of Pure and Apllied Mathematics, 2013
The aim of this paper, we use Stein's method and the w-function associated with the Yule random variable to obtain a non-uniform bound for the point metric of the Yule and geometric distributions. Three numerical examples are provided to illustrate the obtained result.

An Adaptive Human Pilot Model With Reaction Time Delay for Enhanced Adaptive Control in Piloted Systems

International Journal of Adaptive Control and Signal Processing, EarlyView.
This work introduces an adaptive human pilot model that captures pilot time‐delay effects in adaptive control systems. The model enables the prediction of pilot–controller interactions, facilitating safer integration and improved design of adaptive controllers for piloted applications.

3D Coverage Optimization for WSNs Based on Improved Flow Direction Algorithm

Kongzhi Yu Xinxi Jishu
Traditional algorithms often struggle to address the issue of three-dimensional non-uniform coverage in Wireless Sensor Networks (WSNs). This paper presents a three-dimensional coverage optimization algorithm for WSNs, based on an improved flow direction

Tightening Leakage Resilience of the Suffix Keyed Sponge

IACR Transactions on Symmetric Cryptology
Lightweight cryptographic constructions are often optimized on multiple aspects that put the security bounds to the limit. In this respect, it is important to obtain security bounds that are tight and give an accurate and exact indication of the generic

Multi-User and Multi-Task Offloading Decision Algorithms Based on Imbalanced Edge Cloud

IEEE Access, 2019
The mobile edge computing (MEC) technology can provide mobile users (MU) with high reliability and low time-delay computing and communication services. The imbalanced edge cloud deployment can better adapt to the non-uniform spatial-time distribution of ...

Dynamic Precipitation during High‐Pressure Torsion of a Magnesium–Manganese Alloy

Advanced Engineering Materials, EarlyView.
An ultrafine‐grained alloy is produced by high‐pressure torsion of solutionized Mg–1.35 wt% Mn. Precipitation of nanometer‐scale Mn particles during deformation provides pinning sites. This prevents the formation of a bimodal grain structure and results in a finer grain size than for pure Mg.
