Accurate estimation of the state charge (SOC) and temperature batteries is essential to ensure safety energy storage systems. However, it very difficult obtain multiple states battery with fewer sensors. In this paper, a joint method for lithium iron phosphate battery’s SOC based on ultrasonic reflection waves proposed. A piezoelectric transducer affixed surface ultrasonic–electric transduction...

The growing demand for power is putting tremendous stress on existing power plants for generating electricity. The plants are being operated for longer periods of time under heavy load conditions. Reliability of key components of the power plant such as steam or gas turbines and generators is of prime importance. Many utilities are interested in extending the life of turbine-generator component...

Typical ultrasonic methodology for nondestructive scanning evaluation uses systematic scanning paths. In many cases, this approach is time inefficient and also energy and computational power consuming. Here, a methodology for the scanning of defects using an ultrasonic echo-pulse scanning technique combined with chaotic trajectory generation is proposed. This is implemented in a Cartesian coord...

The present research was designed to evaluate an ultrasonic technique for measuring the drawability of low carbon steel sheets nondestructively. This technique, which uses electro magnetic acoustic transducers (EMAT's) is embodied in a fully automatic ultrasonic device called Ultra-Form, which was developed at Iowa State University (by the Center For Nondestructive Evaluation) in 1990. EMAT tra...

The principles of Ultrasonic Computed Tomography (UCT) are reviewed in this paper. The UCT is a powerful nondestructive technique in medicine and recently in industry to reveal an image of a slice of an object or body. The advantage of UCT over other conventional techniques in imaging is that a computed tomogram yields quantitative information about the section of interest. Experimental works o...

Background and Objective: The quality of flat breads depends in part on the textural and structural properties of breads during storage. These properties are largely affected by flour quality. This research aimed at evaluating textural and structural properties of Lavash bread types during storage by different techniques, comparing these methods and determination of correlation between their re...
