This paper presents the application of the Voronoi Fast Marching method to Path Planning of Mobile Formation Robots. The Voronoi Fast Marching method uses the propagation of a wave (Fast Marching) operating on the world model to determine a motion plan over a viscosity map (similar to the refraction index in optics) extracted from the updated map model. The computational efficiency of the metho...

In this paper, a fast frequency domain global modal parameter identification algorithm is proposed. The modal parameters are identified with amplitude square of FRF instead of its traditional real part & imaginary part. By discrete transformation, all additional pseudo roots are reciprocal of the real roots and their conjugates. The physical roots can be separated from mathematical roots with s...

In Drosophila ananassae, artificial selection was carried out for fast and slow remating speed for 10 generations. Response to selection resulted in rapid divergence in remating time in each of two replicates of both fast and slow lines. There were significant differences in mean remating time in females among fast, slow, and control lines. Regression coefficients for both fast and slow lines a...

can be calculated with the FFT and bring the order of arithmetic operations down to Nlog (N) which can be signi cant for large N . This approach, which is called fast convolutions", is a form of block processing since a whole block or segment of x (n) must be available to calculate even one output value, y (n). So, a time delay of one block length is always required. Another problem is the lter...

A highly selective copper (II) coated graphite sensor was prepared by 1,13-bis(8-quinolyl)- 1,4,7,10,13-pentaoxatridecane (kryptofix 5) as a supramolecule ionophore into plasticized polyvinyl chloride (PVC) membrane. The best response characteristic was observed using the membrane composition of PVC = 30.0 mg, dioctyl sebacate (DOS) = 63.5 mg, palmitic acid (PA) = 3.0 mg and kryptofix 5 = 3.5 m...

A major application of the FFT is fast convolution or fast ltering where the DFT of the signal is multiplied term-by-term by the DFT of the impulse (helps to be doing nite impulse response (FIR) ltering) and the time-domain output is obtained by taking the inverse DFT of that product. What is less well-known is the DFT can be calculated by convolution. There are several di erent approaches to t...
