The Strabismus (squint) is one of the most common vision disorders in children. It can bring a discomfort and serious negative impacts on daily life. A timely diagnosis is needed to prevent from getting worse. However, the traditional diagnosis screening is usually done manually and requires expertise, time, and high cost due to the sophisticated equipment. Thus, the proposed automated strabismus detection using computer aided diagnosis can help to reduce time for the ophthalmologist to diagnose the strabismus and the types. The proposed system consists of early stages for the detection of the strabismus: (1) pre-processing as the early stage to get better visualization by removing the unwanted noise and (2) the feature extraction of the iris position to get the information on types of strabismus. The eyes image from the Columbia Gaze Dataset (CAVE), Kaggle: Eye disease datasets and Siblings Database (SiblingsDB) will be used as the input image for the system. Hence, the proposed method in the early stages gives out the value of Mean Square Error (MSE) and Peak Signal-to-Noise Ratio (PSNR) of 0.0003 and 84.35% respectively for CAVE dataset slightly higher than Eye disease dataset and SiblingsDB. By utilizing the image processing approach, this system will be able to assists the ophthalmology and health care practitioners as strabismus screening tools.

This paper is aimed at the effect of surge protection device (SPD) arrangement towards the overvoltage under Differential Mode and Common Mode of operation. Metal Oxide Varistor (MOV) as a type of SPD for lightning surge is used due to its excellent protective ability. The lightning source used in this simulation is an impulse with 10 kA current amplitude and current wave $8/ 20 mu mathrm{s}$. Analysis is carried out when the lightning strikes the three-phase system with different mode of protection. The result shows that in normal condition, MOV acts as an open circuit, while during lightning surges, it acts as a short circuit to discharge the high current to the Ground. Differential Mode consists of four MOVs which are connected between Line to Line and to Ground (3L-G). Common Mode consists of three Metal Oxide Varistors at which each SPD is connected between Lines to the Ground (L-G). Based on simulation results, both overvoltage protections have their strength and weaknesses. It is found that in Differential Mode, the burden of the SPD only occurs on the SPD that connect between L-G when all phases are subject with lightning surges, while in Common Mode, the burden exists at all SPDs. A higher energy-handling capability of SPD is needed for the LG SPD in Differential Mode, and a higher rating of varistor shall be used at each lines in Common Mode to avoid failures.
本文研究了防雷装置设置对差动模式和共动模式下过电压的影响。金属氧化物压敏电阻(MOV)因其优良的防雷能力而被广泛应用于防雷浪涌防雷。本仿真中使用的雷源是电流幅值为10ka的脉冲，电流波为$8/ 20 mu mathm {s}$。对不同保护方式下三相系统的雷击进行了分析。结果表明，在正常情况下，MOV作为开路，而在雷击浪涌时，它作为短路将大电流放电到地。差动模式由4个mov组成，它们在线对线和地之间连接(3L-G)。共模由三个金属氧化物压敏电阻组成，每个防雷器连接在线与地之间(L-G)。仿真结果表明，两种过电压保护各有优缺点。研究发现，在差分模式下，各相均有雷击浪涌时，防雷负荷只发生在L-G之间连接的防雷器上，而在共模模式下，各相均存在防雷负荷。差分模式下，LG SPD需要更高的能量处理能力，共模模式下，每条线路都需要更高的压敏电阻应使用额定值，以避免故障。

There are more than half of the female in the world wearing of high heeled shoes on a daily basis, despite reported on lack of comfort and support. Carrying load with the increased of heel height will significantly can alter the gait pattern which may cause the serious impacts to body musculoskeletal system. This study was performed to investigate the combined effects of the asymmetric load and high heeled shoe to the ankle joints kinetics associated with the changes in lower extremity kinematic parameters. 15 female walked in high heeled shoes with the selection of their preferred walking speeds have been collected in this study. The result revealed that the barefoot gait has longer stride length and step length compared to 2 inch and 4 inch high heeled shoes. The maximum VGRF showed significant changes as the asymmetric load increased. The maximum VGRF of both loaded and unloaded limbs has significant increased as the load weight and heels height increased. Besides, ankle joint force is significant increased as heels height increased. Therefore, women are encouraging to avoid or minimize the wearing of higher heels while carrying heavier asymmetric load.

The vital objectives of this exploration were to design and investigate the polarization independent dual-band metamaterial absorbers. The inner square loop controls the resonant frequency of EM wave at 10 GHz (X-band) as per structure shows a maximum absorption of 99.95% while outer circular loop controls the EM wave resonant frequency at 5 GHz (C-band) of 99.99%. The most interesting finding of this simulated result under oblique incident record over 99% absorptivity variation at different absorber elevation angles ranging from 15° until 75° at every step angle of 15°, thus it be independent polarize in TE and TM mode. The absorptivity variation of the absorber at difference azimuth angles under oblique incidence in both TE and TM polarization at each of the two resonant peaks result state that 15°, 30°, 45° and 60° remains higher than 85% except for 75° at 63% absorptivity response. The normalized input impedance was investigated and reveals that real part of the normalized impedance is near to unity, while the imaginary part becomes zero as there is no reflection.

Microstrip patch antenna (MPA) having UltraWide Band characteristics is a worthy applicant in wireless communications. Mitigating EMI with the narrowband such as 5G lower band, Wi-MAX, WLAN, Satellite band lies in UWB region is a major research concern. This paper presents an UWB antenna containing variable band rejection for avoiding interference with Wi-MAX application. A simple rectangle patch antenna with defective ground structure is used to design UWB characteristics operating from 2.7 GHz – 13 GHz. Band rejections from 3.25 GHz to 3.8 GHz are obtained by utilizing semi-circular slot on radiating patch. Variable band rejection characteristic can be achieved in between 2.75 GHz – 4.4 GHz through altering the value of width of patch. The return loss and VSWR values over the band rejection frequency are close to 0 dB and greater than 2 respectively. In addition, the proposed UWB antenna obtained 85% radiation efficiency over the operating frequency, on the other hand, less than 53% radiation efficiency achieved over band rejection frequency. The proposed antenna is simple in design, compact in size, and efficient in radiation. Hence it is a good candidate on UWB antenna with band notch characteristic for Wi-MAX application.

System identification is finding a model that can describe the dynamic characteristic of the examined system and predict the next output depending on the collected input/output data for that system at previous times. All the real dynamic systems have a nonlinear behavior, but this non-linearity is graduating from a simple to a brutal degree; Mechatronic systems are not spared from this rule. This article presents a real-time nonlinear model for bidirectional DC motor based on block-oriented Hammerstein to avoid the Coulomb friction and its dead zone nonlinear effect with the viscous friction. The recursive weighted least squares (RWLS) method is used to train the Hammerstein network. The mean square error for the system’s closest model is about 9.5 relative to fluctuated output speed from 1870 to -1035 (rpm).

Partial discharge (PD) measurement is widely adopted to estimate the condition of insulation quality. The main hurdle in the monitoring of online PD is the extraction of PD signal from excessive noise originating from the surrounding environment. There is an active research field to tackle this problem and the trend gravitates towards using wavelet denoising techniques. In this work, the feasibility of power spectral subtraction denoising (PSSD) as a PD denoising tool was investigated. In the performance test, simulated noise was used to contaminate the simulated PD signals to emulate real PD signals measured in the field. The denoising test results showed that PSSD is able to achieve higher signal to noise ratio and lower mean square error compared to several variant of wavelet denoising methods.

Generally, a centralized energy management system (EMS) has been used for EMS in a microgrid. However, centralized EMS faces challenges in satisfying the adaptability and fault tolerance. Hence, this study proposed decentralized EMS architecture for optimizing the power dispatch of a microgrid consists of distributed generators. The microgrid architecture comprises of loads and distributed generation system. The dispatch from each distributed source, agent-based decentralized EMS structure, has been used for optimizing the power dispatch. The performances of the microgrid system with EMS evaluated through simulations of generation and load side disturbances.

However, centralized EMS faces challenges in satisfying the adaptability and fault tolerance. Hence, this study proposed decentralized EMS architecture for optimizing the power dispatch of a microgrid consists of distributed generators. The microgrid architecture comprises of loads and distributed generation system. The dispatch from each distributed source, agent-based decentralized EMS structure, has been used for optimizing the power dispatch. The performances of the microgrid system with EMS evaluated through simulations of generation and load side disturbances.
