Journal of ICT, Design, Engineering and Technological Science (JITDETS) focuses on the logical ramifications of advances in information and communications technology. It is expected for all sorts of experts, be it scientists, academicians, industry, government or strategy producers. It, along these lines, gives an exceptional discussion to papers covering application-based research subjects significant to assembling procedures, machines, and process reconciliation. JITDETS maintains the high standard of excellence of publishing. This is guaranteed by subjecting each paper to a strict evaluation strategy by individuals from the universal publication counseling board. The goal is solid to set up that papers submitted do meet all the requirements, particularly with regards to demonstrated application-based research work. It is not satisfactory that papers have a hypothetical substance alone; papers must exhibit producing applications.

Abstract

Transmitted torque is an important performance index of coaxial magnetic gears. This study focuses on the effects of pole-pair numbers on the maximum torque capacity and torque ripple of coaxial magnetic gearsOwing to the magnetic resistance between the pole piece and the medium of air; a torque ripple is generated during magnetic gear operation. In magnetic gear design, maximum torque capacity is considered the higher, the better, and the torque ripple should be the lower, the better. A commercial Finite-element analysis software AN-SYS/Maxwell 2D is applied to simulate the transmitted torque and torque ripple of coaxial magnetic gears by solving the magnetic field, and mechanical motion coupled models. Model parameters, including size and inertia, are designed via the Autodesk/Inventor. The results of finite-element analysis have shown that there are certain relationships between pole-pair numbers and torque performance. It reveals that the sum of the pole-pair numbers is inversely proportional to the maximum torque capacity; the differences of maximum torque between different pole-pair number designs could be up to 82%. However, the torque ripple has not been proven for the relationship. For future research, the torque capability per cost would be necessary for magnetic gear product, especially when the price of rare earth metal is seen rising in the past years. Also, the efficiency of magnetic gear is still important for powertrain system, but it’s not easy to reach both high torque and efficiency, owing to the flux saturation problem. The balance of torque capacity, efficiency, and cost would be the next challenge.

Abstract

This study investigated the axial sensitivity of the aircraft structure to fatigue. Fatigue analysis for an aircraft needs to be done during a design stage to prevent fatigue failure during operation. Fatigue analysis can be done in a time domain or a frequency domain, and frequency domain analysis is more frequently used. Frequency domain analysis for an aircraft normally uses PSD data translated from the vibration experienced for its whole lifetime. If vibration information is insufficient in the PSD, it is supplemented by adding specific loads. In this study, the analysis was done using the PSD data with 7 different additional loads. The life was sensitive to the magnitude and direction of the load, and some loads increase the life. It was found that the aircraft structure is safe from fatigue failure. Since the fatigue test has not yet been carried out, further testing should be done. Also, further study will investigate how to quantify the sensitivity ratio of direction and magnitude of loads under various conditions.

Abstract

In the deep sea, many puzzles have not been solved. We must overcome many difficulties if we want to explore the deep sea. Un- predictable dangers may occur when humans carry out deep-sea exploration. At this time, we can take advantage of Virtual Reality (VR) and the Internet of Things (IoT) characteristics. This paper studies the combination of the IoT and VR that can connect items to the internet, control items and send back data to observe the condition of the equipment and water pressure and break through the space constraints to let people explore the deep sea even in the virtual world. This design will greatly reduce the probability of danger. And the user can achieve the purpose of deep-sea exploration. The ocean is an area that humans have not yet fully developed, and it is also full of mystery and danger. But using VR, you can avoid temperature differences, water pressure and dangerous creatures in the sea. Through VR, you can add new things so that things that can't usually happen in real life can be presented in a virtual way.

Abstract

Facial recognition has been used in several areas such as security, detection of criminals or suspects, etc. The face is considered the most important part of the human body in the person identification process since it can be considered the most important perspective in human identification. This paper proposed a real-time monitoring security system for high secured areas rather than relying on human security officers. The proposed system engages with capturing and detecting the human face using the real-time image segment captured by the web camera through the Viola-Jones algorithm. After detecting the face in the captured image, face identification can be made through the LBP by finding the similarities. Once the identification is made, automatically it recognizes the face. Open Computer Vision (OpenCV) is one of the most efficient machine learning libraries used for Object Detection. OpenCV library is used for detection, and Haar - Cascades are trained to detect certain objects. LBP is used for the face recognition process.

Abstract

Non-Volatile Random Access Memory (NVRAM) is anticipated to be utilized as the performance accelerator of future cloud storage systems. This article aims to analyze how large performance improvement can be expected if we use NVRAM as the performance accelerator of legacy storage subsystems. Specifically, we try to find the best employment of NVRAM with respect to storage performances. To do so, we quantify the hot storage area and replace it with NVRAM to obtain the best performances. Our analysis shows that the source of hot storage traffic is not limited to any single particular storage area, but it is different for application types executed. Specifically, journaling accesses dominate in database applications, while swapping accesses dominate in memory-intensive applications. In some applications such as video streaming, file accesses dominate. Based on these findings, we suggest the usage of NVRAM to maximize the performance improvement of cloud storage systems.
