Radio frequency power amplifiers (RF PA) are widely used for several applications e.g. wireless communication, wireless power transmission (WPT) and radio frequency heating. In general, the choice of power amplifier's operating class is based on requirements regarding linearity and power efficiency. For applications in which linearity is not a critical issue whereas high efficiency is desired, switched-mode amplifier e.g. class E is suitable. Switched-mode operation of class E offers high efficiency with a simple topology, leading to optimal costs of production and system operation. This work presents design and implementation of a high power and high efficiency 13.56 MHz class E power amplifier with parallel load circuit. As a power device, LDMOS was chosen. The fabricated class E PA provides Power-Added Efficiency (PAE) of 94.6% with 21.92 power gain when maximum output power of 44.92 dBm (31 W) is delivered to the load. Industrial, Scientific and medical (ISM) bands Class E PA with parallel load circuit.

This paper presents a flat monopole over rectangle box ground plane. The monopole element is contributed from copper that coated on surface of the FR4 and rectangle box ground plane is contributed from brass sheets. The antenna provides the frequency range of 1.4-3.4 GHz with the return loss <;-15 dB and average gain of 5.5 dBi. The HPBW is 108 degrees in the horizontal plane and 88 degrees in the vertical plane at the central band. The front-to-back ratios are greater than 8 dB across operating band with the ground plane of 80 mm × 50 mm and height of 35 mm. The antenna is suitable to use as a base station antenna.

This article presents the enhancement of bandwidth for rectangular slot antenna with an H and T-shaped slot tuning. The bandwidth was increased from the original antenna by using the T-shaped slot tuning technique and adding the tuning stubs on the both sides of ground plane. The proposed antenna can be applied to ultra-wideband frequency range between 3.1-10.6 GHz based on the IEEE 802.15.3a standard with compact antenna dimension of 30×35 mm2. In designing the antenna, the simulation software, CST Microwave Studio, was used to study and analyze various parameters and characteristics. The simulation and measurement results were agreed fairly well and they showed that the impedance bandwidth was about 130.49% (2.82-13.41 GHz) which was increased from the original antenna by 53.35%, with the average gain of 4.76 dBi possessing bi-directional radiation pattern.

The paper presents analysis of the wave propagation through down-tapered three-layer liquid crystal optical fiber in respect of power confinement due to the hybrid modes supported by the guide. The inner two regions are homogeneous and isotropic dielectrics whereas the outermost layer being composed of radially anisotropic liquid crystal material. It has been found that the guide supports relatively very high amount of power in the liquid crystal region, which indicates the possible use of such microstructures in varieties of optical applications. The effects on confinement due to the positive and the negative (illustrating the taper type) values of taper slopes are reported.

This paper analyzes the insulation level and air clearances of 230 kV air insulated substation. In order to get the BIL, the crest voltage at any equipment are required. By applying simplified calculation method taken from IEEE Std. 1313.2-1999 and IEEE Std. 1427-2006 compared with digital simulation. The simulations have been implemented using simplified models via EMTP-ATP. The BIL required and BIL selected from simplified calculation may give the insulation level not in the range, so the digital simulation would be the better choice. The effect of elevation from sea level as well as the switching surge have been considered for insulation levels and clearances.

In this study, a technique designed to estimate of the autonomic nerve activity with a facial thermogram has been conducted a research and development. Workers feel more mental work-load (: MWL) by advanced information society. Preventing human errors and health hazards with MWL is important. Research activities about MWL, there is the method using thermogram. Thermogram can be taken by non-contact thermometer easily such as a thermography. It can take in the shop floor or life log. But the method needs to measures time-series data at all process of experiment. In addition, if a subject is out of focus of thrmography, it is difficult to estimate MWL. Therefore, measurement environment is limited. In this study, new method are proposed to estimate of the autonomic nerve activity with facial thermogram. If new method with facial thermogram can estimate MWL to high quality, it can use in various situation. Thermograms was taken when a subject solved the issue of a mental arithmetic calculation. And the proposed method has been analyzed by thermograms. As a result of this experiment, proposed method is more sensitive than past technique.

We have developed a portable electronic nose (E-nose) based on eight metal oxide gas sensors for classification and prediction of meat freshness. In this study, the E-nose was applied to predict chicken freshness during different storage days. Principal component analysis (PCA) and artificial neural network (ANN) were used to analyze the experiment data. The PCA method can classify the chicken freshness related to storage days. The ANN result shows good agreement with the PCA result. The correct rate in classification of ANN is 97.92%. From PCA and ANN results, it indicates that the E-nose can well classify and predict the freshness of chicken and owns many advantages over other methods including easy operation, rapid detection, high accuracy, and safety for meat.

Integration of local incremental planning and potential field is proposed for a motion planning of the car-like robot in this research so that obstacle avoidance and goal seeking could be achieved in real time. The feedback linearization control using a desired trajectory generated from the virtual force of potential function could help accomplishing these objectives. Both attractive and repulsive forces are function of both relative position and velocity between robot-obstacle and robot-target. The motion planning of the car-like robot has been demonstrated using this new local incremental planning when the unknown and dynamics environment contains either fixed multiple obstacles or moving obstacles. Results, demonstrated in Matlab simulation, reveal that the car-like robot can reach the target point and avoid moving obstacles at the same time, which could be implemented for a real car robot in near future.

This paper presents a new structure for Lagrange-type variable fractional-delay (VFD) filter. A new structure is formulated from discrete Pascal transform (DPT) and its Pascal interpolation. The computational complexity which obtained from proposed structure is linear function of VFD filter order as same as the so-called Taylor's series structure and also be modular structure. Unfortunately, Taylor's series structure is suffered from transient error that caused from changing delay parameter but the proposed structure can online adjust delay parameter without transient error. Therefore, a transient-free structure will be the new choice for Lagrange-type VFD filters structure which is suitable for real-time application such as sampling rate conversion (SRC) and timing recovery in digital receiver.
