This paper presents research advances in motion planning for humanoid robots, which has been a focus of robotics research in recent years. The twelve-link model of humanoid robot is analyzed. Then the intelligent control techniques on path planning and gait planning have been introduced. The three algorithms of gait planning are fuzzy logic algorithm, neural network algorithm and genetic algorithm. The analysis and estimation aim to provide a typical overview on motion planning for humanoid robots.

Near field studies must be carried out to insulate printed circuit boards and other circuits entirely from outer space. It can be achieved by utilizing the screen properly. These studies must always be made in the near field. The best way known to sense Radio Frequency energy is using a proper loop antenna. The loop probe can be used both as a transmitter and a receiver. If it is loaded resistively, desired flat response between low and high cut off frequency can be obtained. To get accurate results, its physical and electrical parameters must be chosen properly. The most important electrical parameter is inductance of such a loop conductor. Common inductance equations are in general form and they are derived for general calculations. However, loop probes have narrow physical range;they have diameters of a few-centimeters, a few-turn, and have a very thin conductor. So, a certain equation can be derived more accurately. It can be achieved by using conventional empirical derivations or by using modem optimization techniques. (C) 2004 Elsevier B.V. All rights reserved.

The authors present a batch job scheduler for a distributed system which utilises a fuzzy logic algorithm to balance the load on individual processors and maximise the throughput of the overall system. The fuzzyalgorithm has been implemented in a production processing environment rather than in simulation only. The power and simplicity of a fuzzy load balancing algorithm incorporated into a batch job scheduler is demonstrated, producing excellent performance and reliable characteristics.

JPEG has established the first international standards for continuous -tone still image for both gray scale and color. However, since JPEG was originally designed for general applications, some modifications must be done for specific application such as digital still camera. We propose a new method to control the bit-rate of JPEG standard using fuzzy logic algorithm (FLA). A gain factor is determined to get an appropriate quantization matrix, Several rules have been prepared to calculate the gain factor. We used 18 test images for simulations and the results show that the mean error is -1.5 %, standard deviation is 1.5 % and the error range from -3 % to 1 %. Without FLA, the error range from -41 % to 43 %, the mean error is -0.11 % and standard deviation is 24.24 %.
