The work in this paper presents the foldover-free condition for locally constrained image warping. It is based on the radius of influence region and the distance of source and target point, i.e., their proportional relation. The condition is tight, sufficient, but not necessary, and can be used to ensure one-to-one property maintained during the deformation process. Under this condition, the desired image warping without overlap can be obtained.

This paper aims at the high Peak to Average Power Ratio (PAPR) problem, which will occasionally reach the amplifier saturation region and therefore result in signal distortion in OFDM system. By combining the improved C transformation (μ law compression) and the Partial Transmit Sequence (PTS), we present a new method to modify the PAPR property of OFDM system. The simulation results show that the new scheme can get better improvement on PAPR property, compared with the two methods used separately. In addition, the improvement is obtained at the expense of a little BER property of OFDM system as well as a little calculation complexity.

An efficient algorithm for computing 10-point DFT, which can contribute fast algorithms to more N-point DFTs, is developed. The computation of one 10-point DFT requires only 20 real multiplications, 84 real additions and 4 real right-shiftings 2 bits. According to the principles of decimation-in-time (DIT) or decimation-in-frequency (DIF) or double factors algorithm and the efficient algorithm of 10-point DFT, 10M, 10×M, 2M×10, 4M×10-point DFT have their own efficient algorithms, respectively. Thus, many N-point DFTs are possessed of own fast fourier transform algorithms. Especially, in efficient algorithm for computing 10-point DFT, in other words, in radix-10 FFT algorithm, one 102-point DFT requires 720 real multiplications, 1840 real additions and 80 real right-shiftings, one 103-point DFT requires 12760 real multiplications, 28580 real additions and 1200 real right-shiftings 2 bits, and one 104-point DFT requires 183560 real multiplications, 387780 real additions and 16000 real right-shiftings 2 bits.

This paper explicates the simple design of the miniature Tesla coil that have advantages compared to the typical Tesla Coil, which normally has mobility issues due to their bulky size. The proposed design has a similar functionality with the typical Tesla coil where it is able to produce medium voltage with high frequency current at the secondary circuit side. The significant part of the proposed design is that it is without alternating current voltage at the input voltage. The design only needs a low direct current voltage as an input for the primary circuit. According to the Pspice simulation, it proved that the proposed design has the capability to step up the energy and voltage at the secondary winding at least fifty times greater compared to the input voltage. The miniature Tesla coil that has been proposed in this paper is recommended to be use for advance studies particularly on wireless energy evolution.
