An experimental study was conducted to investigate the aerodynamic characteristics of a bio-inspired corrugated airfoil compared with a streamlined airfoil and a flat plate at the chord Reynolds number of Re= 58,000 ~ 125,000 to explore the potential applications of such bio-inspired corrugated airfoils for micro air vehicle (MAV) designs. In addition to measuring the aerodynamic lift and drag ...

This paper investigates and characterizes the aerodynamic performance of a unique platform of airfoils with inflatable, elastomeric actuators. By controlling the inflation of stretchable and tough pneumatic bladders of silicone at specific locations of threedimensionally printed airfoils, experiments demonstrate it is possible to manipulate aerodynamic lift and drag. Measurements on morphable a...

Abstract Adders are one of the most interesting circuits in quantum computing due to their use major algorithms that benefit from special characteristics this type computation. Among these algorithms, Shor’s algorithm stands out, which allows decomposing numbers a time exponentially lower than needed do it with classical In work, we propose three fault-tolerant carry lookahead adders improve co...

We close by describing two rather unusual applications of complex variables. The details are beyond the scope of this book, but the ideas involved definitely deserve mention. The first area of application is fluid dynamics. It was observed already in the nineteenth century that the equations describing the incompressibility and irrotationality of fluids are just the Cauchy-Riemann equations for...

Karatsuba’s multiplication algorithm uses three singledigit multiplications to perform one two-digit multiplication. If we apply Karatsuba’s multiplier recursively, it takes only 3 single-digit multiplications to multiply a pair of 2-digit numbers. This is a significant improvement compared to 4 single-digit multiplications using grade-school multiplier. In this paper, we will use tensor produc...

Three experiments examined the effects of task switching and response correspondence in a psychological refractory period paradigm. A letter task (vowel-consonant) and a digit task (odd-even) were combined to form 4 possible dual-task pairs in each trial: letter-letter, letter-digit, digit-digit, and digit-letter. Foreknowledge of task transition (repeat or switch) and task identity (letter or ...

PURPOSE Anogential distance (AGD) and the 2:4 digit length ratio appear to provide a reliable guide to fetal androgen exposure. We intended to investigate the current status of penile size and the relationship between penile length and AGD or digit length according to birth weight in Korean newborn infants. MATERIALS AND METHODS Between May 2013 and February 2014, among a total of 78 newborn ...
