Chemical / hormonal diffusion is the phylogenetically oldest form of biological action selection. In this paper we argue its persistence in higher animals is a consequence of its utility in solving problems of dithering between high-level goals. Chemical state underlying emotions and drives

Halftones, or periodic cluster dithers, are point-to-point, contone pixel to halftone dot, conversion processes. This paper describes an approach to achieving accurate halftone reproduction by using the errors caused during the scan conversion process without comparison to the source pixels

probability has been open for years. We introduce a new concept of eigenvalue cycles which captures periodicity of systems, and characterize the critical erasure probability based on this. It is also proved that eigenvalue cycles can be easily broken if the original physical system is considered

the impression of having gray scale tones is called halftoning. In the past several halftoning techniques have been developed. For producing regular periodic screen elements, dithering algorithms allow generating both dispersed and clustered screen cells [Hou83]. The halftoning process which is developed

the Tacoma Narrows Bridge to collapse in November 1940. Ku-Band Antenna Dither Vibration page 2 Another form of excitation, aeolian vibration, produces smaller amplitudes in the conductor lines but may cause fatigue and fretting failures after a period of months or years. Also note that I am available

-beam systems, in one and two dimensions. In this paper we propose a novel method of extending the spatial-phase-locking concept to a vector shaped-beam architecture. In the proposed method, an image of a screen grid is superimposed on the projected shape, and this grid image is dithered in X and Y to provide a

-wave) is often traced thicker due to pixel dithering. We exploit the pixel thickness information, for the first time, as a reliable feature for determining periodicity. Results are presented on a database of 16,613 12-channel ECG waveforms, which demonstrate robustness and accuracy of our image-based period

In this paper we design a proportional-period optimal controller for allocating CPU to real rate multimedia applications on a general-purpose computer system. We model this computer system problem in to state space form. We design a controller based on dynamic optimization LQR tracking techniques

Abstract. The apparent scale change due to velocity aberration, although small, has measurable effects on the wide field images of the ACS.Over a one orbit period the scale can vary by as much as 5 parts in 100,000.Across a long diagonal of the ACS field of view this amounts to about 0.3 pixels

, significantly enlarge the pseudorandom output pattern period thus avoiding critical spur tones in the fractional synthesizer’s phase-noise. Behavioral simulations let us verify that the pro-posed technique operates better than a higher order modulator with additive dither. With a low order architecture
