Alzheimer’s Disease (AD) is a neurodegenerative disorder that damages the human brain, leading to dementia. The most difficult challenge that an AD patient faces is forgetting people’s names. The study aims to assist AD patients with a moderate stage by designing a smart glass to identify a person. Basically, it depends on face recognition technology. The glass allows you to track the patient in case of aimless wandering, in addition to talking with the patient. The design was implemented by dividing the system into hardware and software. The hardware consists of the Raspberry Pi 4, Pi camera, ultrasonic sensor, and GPS module. Python coded the software to run a Viola-Jones-based face recognition algorithm. A Local Binary Pattern was used to extract features based on machine learning principles. The Support vector machine (SVM) and the K-Nearest Neighbors (K-NN) were employed as classifiers. A mobile application named “Forget Me Not” was developed to support the patient and the caregiver as well. Results demonstrated satisfaction with the design through capturing one thousand images of 250 people and training the system. Classification accuracy of 84.45% and 93.36% for the SVM and K-NN, respectively, was achieved. Furthermore, the mobile application facilitates the usage of glass. Thus, the study presents an assistance tool for AD patients to coexist with society.

In this research, we propose a new structure of resonators built on a Rogers RO3010 substrate for wireless power transfer (WPT) implant. The resonator’s transmitter (TX) and receiver (RX) are both utilized for the stimulation. The design operates at 0.685 GHz at a transmission distance of 20 mm with a size of (18 mm × 18 mm). The size of the resonator is greatly reduced by considering a high dielectric constant. From literature, it is found that this proposed WPT system design is the smallest in comparison to a similar type of resonator and it achieves strong power transmission efficiency. The coupled resonators are optimized and loaded with defected ground structure (DGS) and integrated with a lumped capacitor. This proposed WPT system can be minimized to a small size, in addition to increasing the transmission distances and improved efficiency. Results indicate that the maximum lg average SAR level is about 1.22 W/kg in agreement with IEEE standard C95.1-1999 for maintaining standard SAR levels. This increases the overall performance efficiency of the WPT system. Also, the WPT system using DGS attains a power transfer efficiency of 98 %. There is a good agreement between the simulated, theoretical, and measured results that have been obtained. All the simulations of the circle-shaped DGS resonator and resonator systems are done in computer software technology (CST) and advanced digital system (ADS).
在这项研究中，我们提出了一种基于Rogers RO3010衬底的新型谐振器结构，用于无线电力传输(WPT)植入。谐振器的发射器(TX)和接收器(RX)都用于刺激。该设计工作在0.685 GHz，传输距离为20 mm，尺寸为(18 mm × 18 mm)。考虑到高介电常数，谐振腔的尺寸大大减小。从文献中可以发现，与同类谐振器相比，所提出的WPT系统设计是最小的，并且具有较强的功率传输效率。对耦合谐振腔进行了优化，加载了缺陷接地结构(DGS)，并集成了集总电容器。提出的WPT系统可以最小化到一个小的尺寸，除了增加传输距离和提高效率。结果表明，该地区最大平均SAR值约为1.22 W/kg，符合IEEE C95.1-1999标准。这提高了WPT系统的整体性能效率。此外，使用DGS的WPT系统实现了98%的功率传输效率。模拟结果、理论结果和实测结果吻合良好。所有圆形DGS谐振器和谐振器系统的仿真都是在计算机软件技术(CST)和先进数字系统(ADS)中完成的。

This paper proposes a pulse-train time amplifier (PTTA) used in a Two-Step Time to Digital Converter (TDC) used as a phase detector in All-Digital Phase Locked Loops (ADPLLs). The proposed PTTA is an all-digital time amplifier based on the concept of time registers. Furthermore, the proposed PTTA has a lower amplification time compared to its counterpart. Therefore, the proposed PTTA allows reduction of the time resolution of the Two-Step TDC at the same conversion frequency or increase of the conversion frequency of the TwoStep TDC at the same time resolution.

Unplanned seizures are caused by a disorder in the central nervous system known as epilepsy. Although significant advancements have been made in the realm of non-EEG wearable devices, there is still much room for improvement in the field of EEG-based seizure detection and prediction using ML. The management of epilepsy has a lot of promise to be aided by non-invasive wearable technology. The suggested study intends to design and implement a support vector machine (SVM) classification-based epileptic seizure detection system based on various wearable devices. The proposed technique for detecting seizures accomplishes According to data for seizure detection, our system consistently achieves a sensitivity of 100% and an accuracy of 97%. High level MATLAB model creation is part of the design cycle. Despite the fact that high performance cannot be achieved with just one signal. Although a high performance detection system cannot achieve the requisite sensitivity and accuracy with a single signal, we presented various combining techniques. RTL modelling, design optimization, FPGA implementation, and functional verification are all included in the implementation cycle. The capacity of the FPGA’s partial dynamic reconfiguration is suggested for implementation in order to make better use of the available resources. Comparing the proposed implementation to relevant earlier work, it demonstrated improved utilization.

In this study, we compare the system performance by considering faster-than-Nyquist (FTN) signaling employing single carrier frequency domain equalization (SC-FDE) and orthogonal frequency division multiplexing (OFDM) under the constraint of a fixed total utilized bandwidth. In this work, FDE also includes the appearance of colored noise, and the corresponding FDEs are formulated based on its effect to improve detection reliability. The advantages of FTN signaling and the preferable choices of compression and roll-off factors based on the bit error rate (BER) and system throughput are demonstrated under multipath fading channels via the simulation results.

Recent advances in cancer treatment using hyperthermia techniques have piqued researchers’ interest in examining and correcting treatment shortcomings. Focused microwave hyperthermia is a technique for treating breast tumors that has the advantages of great precision and few side effects. Breast hyperthermia is a noninvasive cancer treatment in which the temperature of the breast is slightly raised to 39- 45° C by localized electromagnetic irradiation. Traditional hyperthermia techniques envisioned treating single or at most two spherical breast malignant foci with large-scale antenna arrays that required intricate feeding and phase management. This paper proposes a hyperthermia noninvasive multifocal breast cancer treatment using a single multi-beam meta-surface antenna. The proposed method raises the temperature of multifocal irregularly shaped breast cancers while keeping the surrounding healthy tissues at body temperature. Besides, the proposed meta-surface antenna is more efficient where its gain is three times the conventional ones at 2.3 GHz. Instead of employing an antenna array with a complex control unit for each antenna, the proposed antenna will have a single feed and workable control. Although the proposed single antenna element is miniaturized in its size to 65% at 2.4 GHz, the proposal keeps the same number of beams and radiation output. As a result, it will be easy to modify the radiated beams by the sites of the multifocal malignancy. To maintain the temperature of healthy tissues, a new reconfiguration technique for a 3D distribution of antenna beams is developed.

For the purpose of developing chemicals-free soil disinfection technology, microwave heating of a watery rod buried in soil has been investigated by using multiphysics simulation, COMSOL. The soil investigated was loamy soil having 13.77% moisture. A 2.45 GHz microwave was radiated using the standard horn antenna. Temperature of the water rod is found to become higher than the surrounding soil. There is a rod radius showing the highest heating rate. The presence of the highest-rate radius suggests that the microwave technique has the potential to develop a pest control method which can keep beneficial microorganisms alive. To improve spatial uniformity and increase heating depth, the pair-plate guide structure and the use of synthesized waves from double horn antenna are investigated.

An Ultra low-power ultra-wideband low noise amplifier (UWB-LNA) is presented in this paper. The proposed LNA utilizes a common gate input stage followed by a common source stage acting as an output stage (CGCS) in a current reuse configuration. Forward Body-Biasing (FBB) technique is adopted for ultra low-power dissipation. The design achieves high post-layout gain with a maximum of 12.5 dB and a minimum post-layout noise Figure of 3.9 dB. The proposed design drives only 1.68 mA from a 0. 65V power supply. Within the UWB frequency spectrum of interest, the input and output return loss are less than-10 dB and -6dB, respectively. This LNA circuit is designed and simulated in 130nm CMOS Technology.

The Internet of Things (IoT), a solely original computer paradigm, first appeared years ago. Its significance is demonstrated by the way it links the physical and digital worlds to achieve a significant benefit. The IoT is a network of internet-connected devices that enables widespread connections and interactions with other embedded devices, services, and people. With the growing need for smart services in smart cities, this paper focuses on the development of intelligent vehicular management systems in these cities. Here, the devices used in IoT have embedded systems that take the data from the environment. The data is transferred through a wireless network and a gateway to a carrier network. All the data will be stored at Application Enablement Platforms (AEP) which seem like web servers. The data is analyzed through big data analytics platforms. Finally, the devices and gateway remote management platforms distribute the new versions and upgrades to all devices. The primary parameters for determining road conditions include traffic flow rates, air quality, meteorological characteristics, and signal status as indicated by the received signal intensity for both road and intra-vehicular settings. Bluetooth Low Energy (BLE) beacons and mobile applications are employed for smart parking and navigation system, public transportation system, traffic size monitoring, and health-related issues for passengers.

Abo-Zahhad","doi":"10.1109/JAC-ECC56395.2022.10044014","DOIUrl":"https://doi.org/10.1109/JAC-ECC56395.2022.10044014","url":null,"abstract":"The Internet of Things (IoT), a solely original computer paradigm, first appeared years ago. Its significance is demonstrated by the way it links the physical and digital worlds to achieve a significant benefit. The IoT is a network of internet-connected devices that enables widespread connections and interactions with other embedded devices, services, and people. With the growing need for smart services in smart cities, this paper focuses on the development of intelligent vehicular management systems in these cities. Here, the devices used in IoT have embedded systems that take the data from the environment. The data is transferred through a wireless network and a gateway to a carrier network. All the data will be stored at Application Enablement Platforms (AEP) which seem like web servers. The data is analyzed through big data analytics platforms. Finally, the devices and gateway remote management platforms distribute the new versions and upgrades to all devices. The primary parameters for determining road conditions include traffic flow rates, air quality, meteorological characteristics, and signal status as indicated by the received signal intensity for both road and intra-vehicular settings. Bluetooth Low Energy (BLE) beacons and mobile applications are employed for smart parking and navigation system, public transportation system, traffic size monitoring, and health-related issues for passengers.","PeriodicalId":326002,"journal":{"name":"2022 10th International Japan-Africa Conference on Electronics, Communications, and Computations (JAC-ECC)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128220782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
