A low-complexity multi-antenna relaying scheme is proposed for Orthogonal Frequency Division Multiplexing (OFDM) in the presence of Class-A Impulsive Noise (IN).One way and two way relaying are considered.The signal is transmitted and received by two terminal nodes, each with a single antenna in two time phases.In the proposed design, the processin
Multithreshold segmentation of color images is an important part of modern image processing.Multithreshold segmentation techniques that use the ideas of optimization in mathematics to process the information contained in the three channels of RGB images have received much attention in recent years.In this paper, a hybrid algorithm of multiverse opt
[Objectives] The shock environment of a warship in an underwater explosion is the basic input for the design and shock resistance ability evaluation of ship equipment.[Methods] In this paper, a numerical simulation is used to analyze the shock environment in different regions of a ship, and the Second-order Doubly Asymptotic Approximation(DAA2)is u
Photoacoustic computed tomography (PACT) has been widely explored for non-ionizing functional and molecular imaging of humans and small animals.In order for light to penetrate deep inside tissue, a bulky and high-cost tunable laser is typically used.Light-emitting diodes (LEDs) have recently emerged as cost-effective and portable alternative illumi
Logging and tracking raw materials, workpieces and engineered products for seamless and quick pulls is a complex task in the construction and shipbuilding industries due to lack of structured storage solutions.Additional uncertainty is introduced if workpieces are stacked and moved Tanks/Jerseys by multiple stakeholders without maintaining an activ
