    This paper discusses a new design and implementation of a microwave heating for continuous biomass GHz frequency. This new technique is developed to control electromagnetic field distribution inside the microwave heating cavity reactor of biomass carbonization. A chaotic mode pattern microwave generator is used for the technique. The result shows that the technique gives the cost and time-saving, easy to control, and effective performance. © 2012 IEEE.

    Generally, force measurement of nano-scale material widely employs a quartz tuning fork which is resonant mechanical sensors on 32.768 kHz resonance frequency and is powerful tools. But, this paper designs the sensor by using tuning fork on 3 kHz and modifies the tuning fork by a tiny pin adhesive into the end of prong. In experiment, measurements of electrical signal from piezoelectric are study of load-mass effect and pin position. 2 touching techniques are considered: a shear-force type and a tapping mode type with highly position movement system. Silicone rubber, vinyl eraser and hydrogel are elastic material for testing. Results show that both weight and position of pin is significant influencer for resonance frequency and quality factor of sensor. Finally, the tuning fork response experimentation shown this method can be applied to material classification. © (2013) Trans Tech Publications, Switzerland.

    More than two decades, chaos has been attracted many attention from scientists and engineers. Chaotic system phenomenon seems to be random for observers, but it is deterministic for a designer. System of Chaos attractors have been constructed more than a thousand of chaotic patterns. But implementation of chaos in engineering is still needed for real application. For this sake, the research objective is to search for new chaotic applications for Industrial Microwave Heating System without mode-stirring mechanism. The result shows that the performance of the proposed system is better than the conventional system in the rise of temperature. Eventually, the proposed method can be applied in the real application. © 2012 IEEE.
