SPWM-PS control is investigated and employed for the medium frequency DAB DC/DC converter. The used of SPWM-PS control for the converter topology has similar approach as square wave modulation but contains high frequency switching components. The SPWM approach has smoother current waveform than the square wave modulation method. Therefore, the AC voltage waveform can consist of several harmonics component because of the SPWM switching but the inductor current has sinusoidal current waveform that has low harmonics content. This can reduce the current stress in the converter to improve the efficiency and the transformer design method can be simpler. Also, SPWM-PS control can help reduce the reactive power circulation of the DAB converter. The SPWM-PS control is simulated in MATLAB/Simulink at 3 MW, 4/40 kV, and 500 Hz frequency. A 500 W, 24/100 V DAB prototype is also given to validate the converter performance.

To produce human resources who are good at OT security is important task for KOSEN which is closely cooperation with the industry on which faces increasing cyber-attacks. We examined the educational effect and issues on multiple practicing of KIPS (Kaspersky Industrial Protection Simulation) which is based on gamification. Practicing experimental results showed that multiple playing simple contribute to the positive educational effect and we find the possibility of positive skill transfer, however we obtained a great future work which we need the educational contents that can fill the gap of multiple practicing effectively. KOSEN has the big mission that updates the practice-based curriculum constantly.

An effective and computationally less intensive method for the stabilization of a Two-Input Two-Output, TITO, system is presented. The Input-Output (IO) models of the TITO under study are each described by a discrete-time model with its parameters estimated once every sample time. The discrete-time models are used in conjunction with two proposed performance indices to yield control signals to improve the overall system performance. The ability of the proposed self-tuning control scheme to reject small and large disturbances, and to overcome strong couplings in Multi-Input Multi-Output, MIMO, systems are investigated and presented in this study. Simulation tests show that the proposed enhanced self-tuning control scheme is suitable for Single-Input Single-Output (SISO) and MIMO systems.

This paper proposes a new stereo matching algorithm which uses Sum of Absolute RGB Differences. Generally, stereo matching algorithm is sensitive to low texture areas and high noise on images with high different brightness and contrast. To get over these problems, the proposed algorithm utilizes the RGB channels at the matching stage and edge-preserving filter at the second and final stage. The filter is known as Bilateral Filter (BF). The BF kernel well-recovered low texture areas which is able to reduce noise and sharpen the images. Additionally, BF is strong against the distortions due to high brightness and contrast. The propose algorithm produces accurate results on the disparity map for the low textured regions. The proposed work in this paper produces accurate results and performs much better compared to some established algorithms based on the quantitative and qualitative measurements using standard stereo benchmarking evaluation from the Middlebury.

The paper discussed on the bio-signal processing and 2D representation of a near-field radar microwave analysis system using a mono-static ultra-wideband fabric antenna for brain tumor detection. Simulation of a brain tumor was done by developing a brain phantom with tumor using a new composition of agar-agar, sugar and water based on the relative permittivity, ∊r of the real human brain. In the simulation environment, the antenna travelled along planar y-axis and the reflected signals, S11 from the phantom were collected for processing. Five regular window functions and a proposed superposition technique function were applied to determine the reflection point. Following that, the linear interpolation and contrast enhancement technique were applied for a 2-dimensional (2D) representation enhancement.

Electric Vehicles (EV) nowadays are an attractive means of transportation, as they do not emit harmful gasses. Charging of EVs can be achieved through either direct contact or contactless approaches. Contactless charging approach, as Inductive Power Transfer (IPT) system, provides several merits. Yet, the IPT system has several problems; the most severe one is that it causes health issues, since it is based on electromagnetic induction. The alternative method of transferring power wirelessly is the Capacitive Power Transfer (CPT). The basic concept of a CPT system is based on the power transferal via electric fields between the plates. In this paper, a 5kW CPT system is designed with SiC MOSFET-based inverter. A compensating network, connected to the coupling capacitor, is used. The system is then connected to a rectifier to feed a battery. CPT different aspects are studied in this paper. The system is simulated using MATLAB/Simulink and tested experimentally to examine the performance.

The non-linear characteristic of the Power Amplifier (PA) causes system inefficiency and signal distortion when operating in the non-linear region. High Peak to Average Power Ratio (PAPR) in recent high speed wireless communications technology causes Memory Effects, where the PA output signal deteriorates with unwanted scattering and distortion against the ideal signal value. To solve the PA non-linearity effects, Digital Pre-distortion (DPD) is chosen among other linearization methods due to its attractive strengths on ease of implementation, supported bandwidth, flexibility, efficiency and cost. A precise modeling of the PA is required in order to compliment the effectiveness of DPD in terms of resources and performance. Memory Polynomial (MP) has been employed widely in the industry and academia on PA modeling due to its significant resource reduction from Volterra Series. The Memory Polynomial with Binomial Reduction method (MPB-imag-2k) was developed where similar performance is achieved using lesser resources compared to MP. MPB-imag-2k was enhanced into MPB on its Normalized Mean Square Error (NMSE). This paper exhibits the resource optimization in terms of calculation and multiplication operations by using the Calculation Complexity Reduction Ratio (CCRR). CCRR is derived into Multiplications Operations Reduction Ratio (MORR) together with Addition Operations Reduction Ratio (aORR) for both MPB and MP. A modeled ZVE-8G PA and sampled 4G (LTE) signals are used in the simulation. MPB is compared with MP in the non-linearity order range of 1 to 4, pre-amplifier gain (PAG) of 2 to 4, with up to 36dB improvement in NMSE, 57% of MORR and 87.5% of AORR.

Passive radar systems are used to detect targets in various applications by analyzing the acquired reflected signals. This paper presents a design of passive radar that can operate with signals transmitted from various commercial broadcast and communication systems. Vivaldi antenna structure is designed using CST Microwave studio environment to provide wideband characteristics. A phased array of this antenna is developed to allow digital beamforming to differentiate between direct source and target reflected signals. Signal processing scheme is investigated using Simulink environment to correlated source and target signals. Target range and velocity are estimated based on delay and Doppler shift in the received signal. Analysis revealed that more than one target can be identified using the developed system.
