The problems associated with the operation of overhead power lines and ways of improving control over their condition with the help of UAVs are considered. A structural diagram of the system of technical diagnostics of overhead lines based on UAVs was developed, for which the necessary diagnostic parameters were selected according to informative criteria. An analysis of types of UAVs was carried out in order to determine their suitability and efficiency of use for diagnosing the condition of overhead lines.

The large Peak-to-Average Power Ratio (PAPR) is a serious problem in wireless communication systems for mobile and sensor network applications. This paper presents efficient non-linear techniques to solve the large PAPR problem in Single-Carrier Frequency Division Multiple Access (SC-FDMA) system and Wireless Sensor Network (WSN) systems. The performance of the proposed techniques is investigated over a realistic channel model. Simulation results reveal PAPR reduction while preserving low Bit Error Rate (BER) levels. © 2019 Informa UK Limited, trading as Taylor & Francis Group.

IoT enabled elbow range of motion for rehabilitation therapy

In order to analyze and improve in physical therapy, professional sports, and the performing arts, it is crucial to monitor human joint angle movement. For both acute and chronic injuries, as well as to assess how well a treatment is functioning, range of motion assessment is essential. Athletes are more susceptible to fractures from acute elbow injuries (e.g. in gymnasts falling on an extended elbow). The industry standard for assessing joint ROM is now manual ROM measurements using a hand-held goniometer because of their accessibility and ease of use. We now present the fibre optic approach to assess elbow range of motion because the precision and repeatability of manual goniometer measurement have been questioned. In terms of size and robustness, optical fibre technology provides an exceptional solution for motion capture sensing. The method under study is based on an approach that has been used in the past to quantify spine movement and respiration rate: angular displacement between two separated fibres using intensity modulated optical fibre. By adding IoT, all data are uploaded to the cloud, where they are processed and conclusions are drawn for use in Rehabilation therapy using Functional Electrical Stimulation Therapy.

Surgical instrument detection and tracking is one of the core technologies of surgical robots, which can assist clinicians in completing operations. However, existing methods need further improvement in terms of real-time performance and accuracy. We propose a deep learning algorithm, SI-YOLO, for detection of surgical instruments. SimAM attention mechanism is used to improve the feature extraction ability of YOLOv5. Replacing PANet with BiFPN in the neck network improves the feature fusion strategy. The α-IoU loss function is used to improve the regression accuracy of detection boxes. The mAP and FPS of the SI-YOLO reach 99.2% and 120 frames/sec, respectively. Aiming at the problem of ID transformation in the disappearance and occlusion of surgical instruments, the Inception-ResNet-v2 structure is added on the basis of the appearance feature extraction network Cosine of the DeepSort tracking algorithm. Combining SI-YOLO with the improved DeepSort implements the Tracking by Detection (TBD) algorithm. In the case of device disappearance or occlusion, the frequency of ID transitions is reduced by approximately 30%. Finally, we built a simulated surgery experimental platform, established our own data set, and realized the preliminary application of the proposed algorithm. © 2022, The Authors.

Nanoscale Field Effect Transistors (FETs) operating in the Terahertz (THz) range of frequencies rely on the excitation and rectification of the oscillations of the electron density in the device channels - plasma waves. TeraFETs are expected to enable numerous potential applications in THz sensing, imaging, and communications. A new emerging application is for cyber hardware security to distinguish between faked and genuine VLSI chips and predict the VLSI reliability. © 2020 ECS - The Electrochemical Society.

The spread of COVID-19 is incearsing day by day and it has put the entire world and the whole humankind at the stack. The assets of probably the biggest economies are worried because of the enormous infectivity, and transmissibility of this ailment. Because of the developing extent of the number of cases and its ensuing weight on the organization and wellbeing experts, some expectation strategies would be required to anticipate the quantity of evidence in the future. In this paper, we have utilized time series forecasting approach entitled autoregressive integrated moving average, and bend fitting for the forecast of the quantity of COVID-19 cases in Canadian Province for 30 days ahead. The estimates of different parameters (number of positive cases, number of recouped cases, and decrease cases) got by the proposed strategy is exact inside a specific range, and will be a beneficial apparatus for overseers, and wellbeing officials to organize the clinical office in the distinctive Canadian Province. © 2020, The Author(s).

AIP Conference Proceedings 2024年第1期2937卷

In the department of Knee Surgery, measuring the range of motion (ROM) of the knee is a crucial physical examination done for patient evaluation, diagnosis, prognosis, and treatment. The most typical approach is to use a universal goniometer to complete this operation. The range of motion (ROM) can be measured using a variety of instruments, including goniometers, inclinometers, electrogoniometers, and triaxial electrogoniometers. Our proposed solution is to create a digital knee IoT-integrated range of motion measurement device that can measure ROM and all other related data, send the collected information to the cloud for further processing, and make inferences about the patient’s progress, the disease type, the intensity of Stimulation Intensity, and many other things. The device has sensors that assess the knee’s range of motion and should be accurate when compared to the gold standard. Without the help of a therapist, the system’s advantages include the ability to determine knee range of motion (ROM). This work is particularly helpful in the treatment of knee injuries Functional Electrical Stimulation Therapy (FEST).

The design of a 180° output phase difference Wilkinson power divider for L-band applications is detailed in this article. The Wilkinson power is generated through the utilization of the parallel coupler's phase shifter. To showcase the potential of the suggested power divider, an FR4 microwave substrate is fabricated with a narrow band of 1.6 GHz to accommodate radio astronomy systems. The insertion loss, return loss, and isolation loss for the power divider's difference phase are accurately simulated at the operational frequency.
