With the development of the Internet and the large-scale digital music industry, the acquisition and listening of music are presented to users in a more convenient way. How to find the music that users like to hear from the massive digital music data on the Internet has become a key issue in the field of ethnic music information retrieval. Key issues and main goals addressed. there is a complex relationship between ethnic music data, which is suitable for modeling and query processing with data structure. However, the existing query processing algorithms only focus on structural features, and are not optimized for folk music metadata and music content data, and the query efficiency is not high. Currently, the amount of data in various media is exploding, and digital music is everywhere and increasing day by day. At the same time, various music applications have also greatly contributed to the advancement of information technology, such as music sharing, which made the ancient peer-to-peer technology mainstream at the end of the 20th century. the method used in this paper is a deep belief network. Compared with other classification algorithms, its error convergence speed is faster, and the final recognition error for the data set is relatively smaller. © 2024 IEEE.

this paper presents a smart navigation system that uses Building Information modeling (BIM) data extracted from Industry Foundation Classes (IFC) files to generate a graph network for efficient path planning. the proposed method focuses on the construction of a graph networks, and the application of optimization algorithms to estimate optimal paths in a building environment. First, we extract relevant information about the building such as spaces, doors. this data serves to construct a graph network that represents the connectivity and relationships between different spaces in the building. Once the graph network is established, optimization algorithms are used to estimate optimal paths for navigation. the proposed method aims to provide accurate and efficient path recommendations, enhancing navigation in the building environment. the performance of our method is evaluated using a larger graph network derived from a real-world building. the results demonstrate the potential of the smart navigation system in achieving reliable path planning.

Combining the characteristics of brushless DC motor, based on the analysis of the traditional direct torque control with two two conduction, the direct torque control scheme based on extended park transform with three full conduction for brushless DC motor is proposed for the problem of large torque pulsation in the existing direct torque control with phase change. In order that the system can effectively suppress the torque fluctuation caused by the non-ideal counter potential the scheme uses the extended park transform to decompose the current and counter potential waveform constants, and the observed torque and magnetic chain are controlled in a double hysteresis loop, and the applied voltage vector is determined according to the torque and magnetic chain loop outputs and pole positions. Also, to reduce the torque error caused by phase change, a three-phase conduction strategy is used for motor drive. Simulation and experimental results show that the optimized direct torque control system has good torque dynamic response and steady-state performance. © 2023 IEEE.

In order to enhance the efficiency of photovoltaic panels, it is imperative to maintain a low temperature for the photovoltaic module. A recent study delved into this matter, utilizing Response Surface Methodology (RSM) and Multi-objective Genetic Algorithm (MOGA) to optimize the design of the solar system. this was done by examining various parameters, such as the gap, velocity, and solar system temperature. ANSYS software and Navier Stokes equations were used for simulations. the research findings revealed that an optimal gap size of approximately 3 cm was the most effective, with only slight variations in energy gain observed. this highlights the importance of maintaining specific design parameters to ensure optimal performance of solar systems. © 2023 IEEE.

High-speed permanent magnet synchronous motors possess several advantages including high speed, small size, and high power density. these advantages make them extensively utilized in numerous civilian and military applications, including compressors, machining, aerospace, and new energy vehicles. this study involves designing and analyzing a high-speed permanent magnet synchronous motor for a 44kW electric spindle system. Moreover, the segmented skew pole and stator skew slot are compared and analyzed. A normalization method for cost functions based on genetic algorithms has been proposed for solving multi-objective optimization problems. this normalization method optimizes both torque output and torque fluctuations under load conditions. © 2023 IEEE.

With the aggravation of population aging, the incidence of stroke is increasing exponentially, the number of professional rehabilitation doctors is limited, and the application of upper limb rehabilitation robots is becoming more and more extensive. In this paper, a variable-stiffness elbow rehabilitation robot is simulated, and its dynamics are modelling and analysis, and the kinematics and dynamic performance of the robot are explored. Meanwhile, the control method of the robot is optimized to achieve adaptive position control. Finally, through the optimization and improvement of the kinematic parameters of the robot, a good rehabilitation effect is achieved. In this paper, the superior performance of variable stiffness elbow rehabilitation robot is verified by simulation, which provides an effective reference for the application of robot in elbow rehabilitation treatment. © 2023 IEEE.

the industrial Internet of things (IIoT) interconnects an exponential number of industrial devices, and more flexible and low-cost communications are widely in demand. the fifth-generation (5G) communication provides two industrial-target technologies, massive machine-type communications (mMTC) and ultra-reliable low-latency communications (URLLC), to meet the demand. We design a 5G-aided quality test system, where various sensors are connected to the base station (BS) and send contextual information via mMTC. the BS and quality test machine transmit short-length commands and small-size feedback to each other via URLLC. the problem is formulated as a long-term optimization one with the purpose of improving the product qualification rate. We develop a novel contextual combinatorial quality test (CC-QT) algorithm to solve the problem. We further derive a performance upper bound of the proposed CC-QT and analyze its computational complexity. Experimental results illustrate the performance of CC-QT and substantiate its superiority over the existing algorithms.

Real-time constraint satisfaction for robots can be quite challenging due to the high computational complexity that arises when accounting for the system dynamics and environmental interactions, often requiring simplification in modelling that might not necessarily account for all performance criteria. We instead propose an optimization-free approach where reference trajectories are manipulated to satisfy constraints brought on by ground contact as well as those prescribed for states and inputs. Unintended changes to trajectories especially ones optimized to produce periodic gaits can adversely affect gait stability, however we will show our approach can still guarantee stability of a gait by employing the use of coaxial thrusters that are unique to our robot.

A policy that reduces communication overheads by committing together all transactions completed within an interval of time is examined. A model of the system involving two queues served alternatively with preemptions is analysed in the steady-state under Markovian assumptions. An exact and easily implementable solution is derived and is used in order to determine performance measures such as average occupancy or average latency. the optimal length of the operative interval is evaluated numerically. A non-preemptive policy is simulated and is shown to be considerably less efficient than the preemptive one analysed here. A generalization to non-Markovian operative intervals is outlined.
