Friction stir processing (FSP) has been considered as a novel technique to refine the grain size and homogenize the microstructure of metallic materials. In this study, two-pass FSP was conducted under water to enhance the cooling rate during processing, and an AZ61 magnesium alloy with fine-grained and homogeneous microstructure was prepared through this method. Compared to the as-cast materia...

This paper proposes a novel method for hand-gesture recognition based on finger state projection, called FSP Method, which is used to control robotic hands. The control system using FSP Method can simplify the control process of robotic hand considerately while avoiding the drawbacks of traditional hand-gesture recognition methods. The FSP Method measures the projection length of fingers throug...

OBJECTIVES To assess the subjective and objective performance of the new fine structure processing strategy (FSP) compared to the previous generation coding strategies CIS+ and HDCIS. METHODS Forty-six adults with a minimum of 6 months of cochlear implant experience were included. CIS+, HDCIS and FSP were compared in speech perception tests in noise, pitch scaling and questionnaires. The rand...

BACKGROUND Calcification can be detected in both benign and malignant nodules and is often neglected by clinical physicians. The purpose of this study was to investigate the association of thyroid nodule calcification detected on ultrasound with thyroid carcinoma. METHODS One hundred seven cases of thyroid carcinoma and 215 cases of benign thyroid nodules were selected from the records of inp...

Friction stir processing (FSP) 2519-T87 aluminum plate results in enhanced ductility, 25% strain at fracture. However, the yield strength in the FSP zone drops to 175 MPa from �400 MPa. Actively cooling the plate during FSP increases the yield strength to 185 MPa and decreases ductility to 20% strain at fracture. Thick bending of a plate of the alloy was demonstrated after the surface was subje...

BACKGROUND The objective of this review was to compare the efficacy of Fallopian tube sperm perfusion (FSP) with intrauterine insemination (IUI) in the treatment of non-tubal subfertility. METHODS The principles of the Cochrane Menstrual Disorders and Subfertility Group were employed. Only randomized controlled studies comparing FSP with IUI were included in this review. The main outcome meas...

Corrosion behavior of friction stir processing (FSP) WE43 alloy in a simulated body fluid (SBF) was investigated. Micro-galvanic corrosion was the dominated corrosion behavior, and the corrosion resistance of FSP WE43 alloy was improved compared to the cast counterpart. Furthermore, due to the fine-grained and homogeneous microstructure, uniform corrosion morphology was observed on FSP WE43 all...
