Sphere anemometer - a faster alternative solution to cup anemometry

On Cup Anemometer Rotor Aerodynamics

The influence of anemometer rotor shape parameters, such as the cups' front area or their center rotation radius on the anemometer's performance was analyzed. This analysis was based on calibrations performed on two different anemometers (one based on magnet system output signal, and the other one based on an opto-electronic system output signal), tested with 21 different rotors. The results we...

MJH: A Faster Alternative to MDC-2

In this paper, we introduce a new class of double-block-length hash functions. Using the ideal cipher model, we prove that these hash functions, dubbed MJH, are asymptotically collision resistant up to O(2n(1− ) query complexity for any > 0 in the iteration, where n is the block size of the underlying blockcipher. When based on n-bit key blockciphers, our construction, being of rate 1/2, provid...

A Faster Alternative to SSS* with Extension to Variable Memory

The two best known and most frequently referenced minimax search methods for game trees are Alpha-Beta [2] and SSS* [6]. The algorithms are quite dissimilar in structure and properties. Alpha-Beta is a depth-first recursive procedure that needs little memory to execute. Although it evaluates more terminal nodes than SSS*, it generally runs considerably faster owing to its low overhead. In contr...

On Faster Sphere-Box Overlap Testing

We present faster overlap tests between spheres and either axis-aligned or oriented boxes. By utilizing quick rejection tests, faster execution times are observed compared to previous techniques. In addition, we present alternative vectorized overlap tests, which are compared to the sequential algorithms. Source code is available online.
