By the year 2030, there is expected an increase in hip arthroplasties between 43% and 70% compared to 2014. For this reason, a novel investigation was conducted in 2023 under the supervision of the Professional School of Mechatronic Engineering at Ricardo Palma University, focusing on a proof of concept for the design of a hip prosthesis using mechanics of materials analysis and finite element method. the mechanical design of the implant indicated that to withstand a weight load of Q=2300 N and achieve resulting displacements (URES) less than 0.008 mm, the minimum safety factor required is 3.93, as a result of the finite element analysis (FEA). the electronic design, consisting of an Arduino Mega 2560, two potentiometers, two MG996R servo motors, a MPU6050 accelerometer, and an OLED display, resulted in a voltage consumption of 5V separately for the control board and the others sensors and actuators. SolidWorks was used for stress studies, URES, and safety factor analysis in this design. Von Mises stress analysis revealed a maximum of 87.8 MPa at the stem-joint junction, while URES analysis determined a maximum displacement of 0.008 mm. In conclusion, favorable results were achieved. For future research, it is proposed to consider other geometries for the cross-section, optimizing the design, and conducting experimental studies of the loads.

Blockchain is a foundational technology that has the potential to create new prospects for our economic and social systems. However, the lack of scalability limits the capability to deliver a target throughput and latency compared to the traditional financial systems. Layer-two is a collective term for solutions designed to enhance scalability by handling transactions off the main chain. For example, bidirectional payment channels allow the execution of fast transactions between two parties, thus forming the so-called payment channel networks (PCNs). therefore, efficient routing protocols are needed to find a payment path from the sender to the receiver, with the lowest transaction fees. these protocols have to consider, among other factors, the unexpected online/offline behavior of the constituent payment nodes and the payment channel imbalance. this study proposes a novel machine learning-based technique for off-chain transaction routing. It is a fully distributed approach to be used within PCNs. For this purpose, the effect of the offline nodes and channel imbalance on the payment channels network are modeled. the simulation results demonstrate that the proposed technique strikes a good balance when considering the success ratio, transaction fees, routing efficiency, transaction overhead, and transaction maintenance overhead compared to other techniques that have previously been proposed for the same purpose. © 2021 IEEE.

Cloud computing is the use of a virtual repository of resources dispersed throughout the Internet. It is a development of computer technology that is based on the Internet. Depending on their demands, several levels of users can access cloud computing services. However, data security on the Internet is the most crucial concern for cloud computing. Confidentiality, security, anonymity, and authenticity are common problems experienced by both cloud service providers and customers. Cloud service users do not have complete access to or control over these services. However, the cloud service provider must guarantee that the client’s login information is safe. To strengthen cloud security, we were able to recognize and look at a wide range of encryption problems. A hybrid framework for cloud computing security is taken into consideration based on these techniques.

Visual Simultaneous Localization and Mapping (Visual SLAM) is considered to be one of the important foundations for mobile robots to move toward intelligence, which gives robots the ability to autonomously locate and construct maps in an unknown environment. In the past decades, great progress has been made in the field of visual SLAM, relatively mature algorithm system and program architecture are gradually developed. However, the current researches on visual SLAM mostly assume that the surrounding environment is static, which greatly limits the application of SLAM systems in real world. Aiming at the urgent need of mobile robots for precise localization and map construction in dynamic environment, methods are proposed in this paper. Image semantic segmentation based on deep learning and multi-view geometry methods are combined to recognize and segment moving objects. Only background features are used for camera tracking to avoid the impact of moving objects. Furthermore, an experimental platform is built using RGB-D camera and motion capture device, the effectiveness of the algorithm is verified by public datasets and real scene data. © 2020 IEEE.

Given the trajectory of the industrial robot in Cartesian space, the existing methods only consider the kinematic constraints when optimizing the time trajectory planning, and ignore the maximum driving ability of the motor, which is likely to cause an overrun alarm and greatly reduce the trajectory accuracy. therefore, this paper studies the time-optimal trajectory planning algorithm based on dynamics. Firstly, the algorithm discretizes the path, calculates the Cartesian coordinates of each discrete point and the differential about the path length. then, this algorithm considers the constraints of dynamics and kinematics, uses the principle of linear programming, recursively calculates the upper limit value of speed and the maximum acceleration value at each discrete point, and calculates the speed value at each discrete point and keeps it within its allowable ranges. Finally, this algorithm uses the speed to calculate the corresponding time of each discrete point, and according to the interpolation period, outputs the path position of each period, the position and orientation in the Cartesian space and joint parameters. the MATLAB program is written to verify the feasibility and efficiency of the algorithm. © 2020 IEEE.

Myoelectric signals from the human motor control system can improve the real-time control and neural-machine interface of robotic leg prostheses and exoskeletons for different locomotor activities (e.g., walking, sitting down, stair ascent, and non-rhythmic movements). Here we review the latest advances in myoelectric control designs and propose future directions for research and innovation. We review the different wearable sensor technologies, actuators, signal processing, and pattern recognition algorithms used for myoelectric locomotor control and intent recognition, with an emphasis on the hierarchical architectures of volitional control systems. Common mechanisms within the control architecture include 1) open-loop proportional control with fixed gains, 2) active-reactive control, 3) joint mechanical impedance control, 4) manual-tuning torque control, 5) adaptive control with varying gains, and 6) closed-loop servo actuator control. Based on our review, we recommend that future research consider using musculoskeletal modeling and machine learning algorithms to map myoelectric signals from surface electromyography (EMG) to actuator joint torques, thereby improving the automation and efficiency of next-generation EMG controllers and neural interfaces for robotic leg prostheses and exoskeletons. We also propose an example model-based adaptive impedance EMG controller including muscle and multibody system dynamics. Ongoing advances in the engineering design of myoelectric control systems have implications for both locomotor assistance and rehabilitation.

Lightweight computing technology is the trend of future information technology. Related research technologies are applied to electronic health records and electronic medical records, and only consider the mutual authentication of users and the confidentiality of data transmission. In addition, most researches still rely on time-consuming modular exponential calculations, elliptic-curve based signatures and encryption algorithms. However, few studies can fully consider the development of lightweight access control mechanisms for health care information database systems. Physically Unclonable Functions (PUF) devices are based on unique physical changes that occur naturally in the semiconductor manufacturing process, resulting in unique identification and unpredictability. they are used in authentication and encryption mechanisms and have significant improvements in performance. this investigation discusses and analyses on the privacy protection, authorization and access control characteristics of the health care information database, and develops a secure and efficient access control scheme by using PUF technology for health information systems. the proposed access control scheme not only improves the privacy and security of patient medical records, but also makes the entire medical process more efficient. © 2021 ACM.

the principal cause of upper limb amputations is due to traumatism. the prosthesis is an assistive device to help in the activities of daily for the amputee person. However, one of the latest reports shows that in developing countries there are around 30 million people without assistive devices. this work presents the development of two kinds of sensors for the PrHand, an upper limb prosthesis based on compliant mechanism and soft-robotics. the sensors are made with polymeric optical fiber (POF), due to their flexibility and low cost, and the working principle is based on intensity variation. the angle sensors are used for monitoring the interphalangeal joint of the fingers, and for the assessment were made cycles of closing and opening each finger. On the other hand, the force sensors are located at the tip of three fingers to track the force made over the objects. Before encoring the sensors were evaluated making five cycles of compressing and decompressing each sensor. the results show a linear behavior between the angle and the voltage variation, one most remarkable angle sensor result was with a sensibility of 0.0357 V/° and an R2 of 99 % closing and 0.0483 V/° opening. In the case of the force sensor, a polynomial relation was found between the voltage changes and the pressure over the sensor;in some cases, the relation between voltage changes and pressure could be linear but that depends on the construction of the sensor. Regarding the obtained R2 of 99 %, its sensibility was 0.0361 V/N compression and 0.0368 V/N decompression. In conclusion, was successfully developed two kinds of sensors for the instrumentation of PrHand prosthesis. It is expected to use angle and sensor variables as input in algorithms of Machine Learning to improve the detection of objects. One aspect to improve is to control in a better way the sensor construction parameters due to the considerable influence over the sensor behavior. © Published under licence by IOP Publishing Ltd.
