This paper presents technique to design current, speed controller using field oriented vector control(FOC) for interior permanent magnet synchronous motor(IPMSM) using a novel simplified SVPWM algorithm. The internal model principle is applied to tune the current loop of ipmsm. To simplified the current loop design procedure, PI controller parameters are directly expressed in terms of machine parameters and desired closed loop bandwidth. Maximum torque per ampere(MTPA) method is used to improve the overall efficiency of motor drive system by injecting demagnetizing current component. A computer simulation shows the validity and effectiveness of proposed algorithm.

In the past two decades, there has been a sharp rise in the use of deep learning for medical image processing and analysis. Recent challenges, for instance, the most well-known ImageNet computervision competition, have almost entirely incorporated deep learning approaches for providing the best result. The concept of Image classification was later extended to Image Segmentation and Object Detection which proved to perform extremely well using state-of-the-art classification algorithms as their backbone architecture. The accuracy of the algorithm and approach has a significant impact on the medical field as there is a constant need for accurate and computationally efficient models. The existing object detection and segmentation approaches need large data for providing accurate results, unlike classification algorithms in which accuracy can be achieved with a relatively smaller amount of data. Hence, for the overall increase of model accuracy, there is a need for image augmentation to be incorporated. In this paper, several deep learning methodologies such as classification, object detection, ensemble, and segmentation for pneumonia classification and detection have been reviewed and an ensemble-based approach for the classification of Pneumonia using chest X-rays has been proposed.

Numerous studies believe that bone mineral density (BMD) is the only technique that fundamentally reveals bone strength, despite the fact that the latter provides important information regarding the risk of osteoporotic fracture. Analyzing macro- and micro-structural characteristics quantitatively may improve beyond simply estimating bone density. Bone structural information can be obtained using non-interfering, non-carnage procedures. According to many research, bone mineral densitometry (BMD), which also provides important information on osteoporosis, primarily measures bone strength. Numerous works in the field of photo-domain computervision have introduced efficient strategies that benefit from different viewpoints on the same instance in other domains such as self-supervised and semi-supervised learning. In order to tackle these problems we are using a simple yet efficient method termed as multi-view ct network or mvctnet along with multimodal data fusing technique called Early Fusion. Utilizing cutting-edge methods and technologies will improve image analysis in multi-view CT scanning for osteoporosis detection, increasing the precision and effectiveness of osteoporosis detection.

Aiming at the uncertainty factors such as large inertia, large delay and nonlinearity in the three-tank water level control system, an intelligent control algorithm of Beetle antennae-particle swarm optimization was proposed. Firstly, on the basis of establishing the mathematical model of the three-capacity water tank, the BAS-PSO algorithm is designed, which increases the ability of individual to learn the surrounding information independently on the basis of maintaining the group optimization search and learning the global optimal, and continuously iterates the optimization until the optimal solution is found. Secondly, 5 examples of benchmark test functions are selected for performance testing to evaluate the local search ability and global development ability of the algorithm. Finally, the simulation results show that compared with the traditional intelligent control algorithm, the BAS-PSO algorithm can effectively improve the speed and robustness of the system.

Advances in deep learning techniques have made computervision tasks more accurate and faster by relying on convolutional neural networks and more powerful hardware. In industry, automatic inspection supported by these methods is capable of offering constant maintenance and avoiding accidents on railways. Thus, this work proposes the application of deep learning and image processing methods to perform the automatic inspection of wheel sets in train cars. More specifically, the size of the wheel and the thickness of the bandage are measured, in addition to locating the bearings' fixation screws. The constructed neural network performs semantic segmentation on photographs provided by the mining company Vale. Using a U-Net architecture, with ResNet50 as a backbone, the network was able to reach 92.50% in mIoU and 97.52% in mPA, metrics adopted to evaluate this proposal. The post-processing step recovered the screws and improved the evaluation metrics, indicating the success of the proposed inspection.

The advent of deep learning combined with computervision has brought forth unparalleled advancements in facial detection and landmark identification. One pivotal player in this transformation has been the YOLO (You Only Look Once) series, setting new milestones in object detection methodologies. Our research is centered on harnessing the YOLOv8 model to optimize face detection processes. We incorporate the OpenCV library for image processing, enhancing detection fidelity through adjustable parameters like confidence and intersection over union (IoU) thresholds. A standout feature of our methodology is its innate ability to adjust to diverse image proportions. This is achieved by innovatively resizing and padding input images, which not only maintains consistency in detection but also augments accuracy. The proposed technique not only demarcates the face but also pinpoints facial landmarks, thus offering a comprehensive spatial map for each detected face. Preliminary results on benchmark datasets underscore the model's dual advantage of speed and precision. Our approach promises not only improved face detection but also paves the way for its amalgamation into expansive facial recognition and analytic platforms.
