if but a single square cm. on each glass face radiates toward m. As there are a number of such square cms., contributing radiation, the coefficient of (3) would be decreased ten or twenty times. One may conclude I think that AO compared with AYr is numerically much in excess. This implies too large a AO, to persist in a room of practically constant temperature, in the summer. It is thus more th...

We present a new type of photonic structures in quadratic nonlinear materials that enable efficient and continuous all-optical deflection. The structures are based on two-dimensional modulation of the nonlinear coefficient and consist of a set of symmetric or anti-symmetric arcs that form a periodic pattern in the propagation direction and a chirped pattern in the transverse direction. Stoichio...

Controllable parafoil and payload aircraft are controlled with downward deflection of left and right parafoil brakes. Lateral control is obtained by differential deflection while longitudinal control is created by collective deflection of the left and right side parafoil brakes. The work reported considers an alternative method to control parafoil and payload air vehicles by tilting the parafoi...

This paper presents explicit analytical solutions of the pressure coefficient and the pressure ratio across the oblique shock and expansion waves in function of the flow deflection angle. These new explicit pressure-deflection solutions can be efficiently used in solving applied aerodynamic problems in supersonic flows, such as the aerodynamics of airfoils and wings in supersonic-hypersonic flo...

We propose two novel electro-optic (EO) deflectors based on two new nonrectangular geometries: the parabolic and the half-horn configurations. These devices not only provide excellent deflection angles, but also have the potential to build nonblocking 2 x 2 optical switches. A deflector figure of merit is defined, and comparisons with existing EO deflectors are given. Devices fabricated in LiTa...

Deflection profiles of y} and y are shown in Fig. 1 for M -100 kg, 7=490 kN, c = 307 m/sec, a = 226 m/sec, at t = 0.68, 1.02 ane 1.29 sec. At these times the mass positions are * = 52, 118, and 188 m. As shown in Fig. 1, maximum deflection is at the mass location. To determine the adequacy of the simplified mathematical model used in the analyses, the cable deflection at a known position was mo...

The steady state behavior of regular two-connected multihop networks in homogeneous load under hot-potato and single-buffer deflection routing is analyzed for ultrafast optical applications. Manhattan Street Network and ShuffleNet are compared in terms of throughput, delay and deflection probability both analytically and by simulation. It is analytically verified that single-buffer deflection r...

results the rate of first-time successful spinal needle insertion was not significantly different between the clsp and tsp groups (62.9% versus 55.7%, p > 0.05). ease of landmark palpation in the clsp group was not significantly different from that in the tsp group (86.7% versus 76.4%, p > 0.05). the number of needle-bone contacts in both groups were not significantly different (p > 0.05). the ...

Microcantilever-based sensors can be used to detect molecular absorption of, for example, hydrogen gas, which causes changes in the surface stress, leading to deflection of the cantilever. Such a deflection can be determined by means of optical beam deflection, capacitance-, or piezo-resistance based readout. We have recently proposed a compact integrated mechano-optical sensor using a novel an...

The right-hand rules show the direction of the spin-induced deflection of baseball pitches: thus, they explain the movement of the fastball, curveball, slider and screwball. The direction of deflection is described by a pair of right-hand rules commonly used in science and engineering. Our new model for the magnitude of the lateral spin-induced deflection of the ball considers the orientation o...
