    Control strategies modeling for robotic exoskeletons facilitating sit-to-stand transitions in geriatric and lower limb impaired

    With the growing global aging population, there's been an amplified societal emphasis on preserving the health of the elderly and enhancing their quality of life. In this scenario, robotic exoskeletons have emerged as a cutting-edge solution to assist the elderly and those with lower limb muscle deficiencies in Sit-to-Stand (STS) exercises. These exoskeletons adopt two main approaches: full assistance for those with entirely weakened lower limbs and partial assistance for those with some remaining muscle strength. This article introduces two modeling methods and concepts for these control strategies, aligning with the full and partial assistance directions, respectively. Both approaches hinge on the Lagrange equation as their foundational structure, integrating distinct kinematic designs to form their individual dynamic models. Based on this, the models are further adapted to address the specific risks associated with STS activities as per each strategy. Research outcomes highlight that by assessing the wearer's EMG signal, the partial assistance strategy considerably mitigates the lower limb muscle strength required for STS under conditions such as low-speed, medium-speed, sitback-like, and step-like. This not only improves balance but also augments the likelihood of successful STS execution, consequently diminishing fall incidents.

    Design and optimization of CMOS based 4-bit comparator

    The paper primarily focuses on optimizing circuit delay and energy consumption, specifically in gate-level circuits. Three methods are employed for circuit optimization. The first method aims to minimize transistor usage to reduce both delay and energy consumption. The second method involves prioritizing logic gates based on underlying hardware, favoring simpler circuit structures whenever possible, given that our design primarily revolves around logic gates. The third method entails adjusting the number of stages to enhance delay optimization. To validate these rules, three distinct circuits were designed to implement a 4-bit absolute value comparator, each corresponding to one of the rules. Through simulation, calculation, and comparison, the best circuit was identified, providing validation for the rules. The second part of the paper shifts its focus towards optimizing delay and energy consumption by adjusting the sizing of logic gates and the supply voltage to achieve optimal overall performance. In conclusion, further research is needed to corroborate these three rules and identify additional rules, laying the foundation for intelligent circuit optimization.

    Predictive modelling based on statistical modeling of logistic regression for heart disease

    The heart is the core driving force for the continuation of human life, and the disease of this organ is bound to be fatal. There are two main types of heart disease. Congenital diseases are caused by developmental problems in unborn children. These problems, mainly in the heart, can damage various parts of the heart. Acquired sexually transmitted diseases are diseases caused by environmental factors and their own growth and development after birth. The purpose of the project model is to predict heart disease and analyse the main types of heart disease in the population. In the whole research process, the most important thing is the establishment of the model. The algorithm principle of this model is logistic regression. Logistic regression is used to make predictions and probability calculations on the data.

In addition, prevention of heart disease can be improved with accurate and convenient model predictions that can be tailored to the population that fits the predictions. This method can improve the technical level and treatment level of the hospital, and can also reduce the harm caused by heart disease.

    Self-avatar: Monocular 3D human reconstruction from RGB image

    3D human position and shape estimate are crucial in many computer vision applications. Despite the fact that there are numerous deep learning techniques designed to handle this problem, they frequently only use training networks with RGB images from a single point of view. In this paper, a unique approach to solve this issue is proposed by combining a regression-based multi-view picture learning loop with an optimization-based multi-view model. This is because some public datasets are collected by multi-view camera systems. A parameterized human body model's position and shape parameters are initially deduced by a convolutional neural network (CNN) from multi-view photos. This work then introduces an enhanced multi-view optimization method called MV-SMPLify, which aligns the SMPL model with multi-view images by using the regressed pose and shape as beginning values. Following that, the CNN model's training can be monitored using the optimum parameters. The Self-avatar project as a whole is a self-supervised framework that combines the advantages of both the CNN method and the optimization-based strategy. Additionally, the use of multi-view photos improves thorough supervision during training. This methodology outperforms earlier methods in a variety of ways, according to qualitative and quantitative testing using open datasets.

    Logistics warehousing system shelving station route planning based on X-ARM

    The need for automated control in warehouse and logistics systems has increased recently, particularly in the area of cargo storage. The use of robot arms in manufacturing is an important area for development. Multi-arm actions, including switching between multiple arms, expand the number of potential operations that numerous operators can do, but they also bring more computing hurdles. Multiple robotic arm systems must operate with careful path planning. In this study, Based on previous research papers, we propose the utilization of dRRT* and mmdRRT* algorithms for efficient path planning. The dRRT* algorithm improves exploration and convergence to an ideal path by combining the advantages of the rapidly-exploring random tree (RRT) with the optimal RRT* algorithm. To address complicated and dynamic situations, the mmdRRT* algorithm, on the other hand, uses a multi-modal distribution model. We want to improve the reliability and effectiveness of path planning for various robotic arm systems by combining these two techniques.
