This paper describes an experiment of integrating three courses at the Brazilian Aeronautics Institute of Technology, within the Electronic and computer engineering graduate program on the 1st semester of 2011. A smart grids system was used as a Problem Based Learning (PBL) strategy together with an agile method and best practices within a project developed on three courses: CE-240 Database Systems Project, CE-245 Information Technologies, and CE-229 Software Testing. Students of these courses had to interact, in order to produce a prototype of a smart grids system, simulating a real project development. At the end, a survey among students has proved that the integration of practical exercises has provided higher levels of understanding and problem solving capabilities, improving students' knowledge. The survey also has shown that communication between students from different courses should be improved. The major findings of this paper were that the integration of the three courses was favorable by 83% of the surveyed students, and most students (73%) have considered that their knowledge was improved. Authors recommend the use of practical exercises, courses integration, and PBL to considerably increase the quality of electronic and computer engineering courses.

This paper shows the design and implementation of a multi-resonant Class-E 2 DC-DC converter based on voltage- controlled oscillator. By cascading a Class-E inverter to a Class-E rectifier, a double soft-switching converter is obtained, in which, the active switch turns-on with zero voltage switching and the diode turns-off with zero derivative voltage switching. This work relies on design equations based on normalized charts that relate the resonant frequency to the current transfer function, quality factor and peak values for the switch variables. In order to activate the switch, a circuit scheme is proposed based on a voltage-controlled oscillator connected to a low-side gate-driver. Therefore, it is not necessary to use a microcontroller neither auxiliary power sources. Experimental results are presented to show the feasibility of the proposed converter.

We have carried out experimental and numerical analyses for reconstruction of permittivity distribution using a pair of long distance small size electrodes and additional arc electrodes. A reconstruction method for permittivity distribution that uses a genetic algorithm and numerical analysis (finite element method) based on measured capacitance has been proposed and investigated. However, the conventional method had a problem in accuracy. In this paper, the reconstruction method has been improved by using a Parameter-free Genetic Algorithm(PfGA) based on measured capacitance and electric potential. In addition, we have evaluated the fitness function with PfGA. © 2016 The Institute of Electrical Engineers of Japan.

The Impact of Hot Carrier Injection-Induced Device Degradation for Lower-Power FinFETs

The impact of hot carrier injection (HCI) on the performance of standard and low-VT FinFETs are investigated and benchmarked with each other. For this investigation, these FinFETs were fabricated with various gate lengths (L) from 16 to 36 nm. HCI-induced transconductance degradation in standard devices for gate length variations of 36 nm down to 16 nm was 75%, while it was 35% for low-VT devices. Similarly, the degradation of threshold voltage in standard devices for gate length variations of 36 nm down to 16 nm was 39%, while it was 36% for low-VT device. In this work, as the device is subject to HCI, we found that: (1) short-channel devices cause severe degradation on the threshold voltage and transconductance (gm) compared to long-channel devices, owing to the higher electric field for short-channel devices at the gate edge, (2) standard devices exhibit a more stable threshold voltage than that of low-VT power devices, since the TiN barrier layer prevents Al atom diffusion into the HfO2 layer, and (3) the transconductance efficiency of standard devices is better than that of low-VT power devices. Further, the lower-VT devices show lower transconductance degradation than standard devices. However, the transconductance degradation of the long-channel standard and low-VT devices are the same. Compared to short-channel low-VT devices, extended-channel standard devices are more immune to the HCI effect. © 2022, The Minerals, Metals & Materials Society.

Crystal growth of Rb2CdI4 was performed by Czochralski method. Transparent colourless crystals with monoclinic structure were obtained. Temperature dependence of the dielectric constant along the b-axis was measured with variation of frequency. The thermal expansions x i (i = a, b, c and a′;a′ = a + c) along the four independent axes were measured both by clip-type strain-gauge dilatometer and X-ray diffraction methods. These results show distinct anomalies associated with the ferroelectric transition at TC= 210 K. Copyright © 2010 Taylor & Francis Group, LLC.

Attendance systems have become more modern, and one of the biometric systems without physical contact is face recognition. However, many face-based attendance systems still carry out attendance individually and cannot detect multiple faces simultaneously. In addition, capturing facial data in real-time is still a challenge because the relatively large distance between the camera and the individual reduces the ability to recognize faces. The general solution is to use super-resolution to generate better-quality faces while maintaining the main facial recognition features. One technique still being researched is super-resolution generative adversarial networks (SRGAN). SRGAN can enlarge the resolution of captured images and maintain image quality sufficient for face recognition. The attendance system can be easily integrated into edge devices such as the Jetson Nano. This paper proposes automatic and effective attendance systems with the super-resolution technique to detect and recognize faces in low-resolution input. The experimental results show that using face data capture with a resolution of 40 × 40 pixels and a four-fold magnification results in a resolution of 160 × 160 pixels. Combining Face SRGAN with FaceNet architecture as the basis of face recognition can achieve an accuracy rate of 78.19% and an F1-Score of 81.13% with an average processing time of 1.61 seconds per frame on a PC and 14.55 seconds per frame on a Jetson Nano at an average of face recognition per frame of as many as up to 8 faces simultaneously.

In this paper, an optimal motion-sensing technique of indoor children's accident prevention system has been developed. There is a drawback in the existing detection algorithm due to the environment in a manner that recognizes the difference between the 1% and more frames of motion recognition accuracy. The proposed motion detection method is based on the background modeling technique to improve the accuracy. The method is obtained using the technique to solve the recognition errors arising from the surrounding environment. We are easy to recognize the danger area using mobile cloud-based smartphone, and provide notification to tell, remote control when children access to danger area. Also, for people to recognize the size of the minimum recognition (blob) to be able to adjust the children and to recognize accurately, we improve the existing algorithms. Through the experiments, based on an improved algorithm, we derived the optimal value for children.
