Thin-walled components, known for their lightweight and high-performance characteristics, hold significant strategic importance in industries such as aerospace, radar, and transportation. However, due to their inherently low stiffness—encompassing shear, bending, and torsional stiffness—these components are highly susceptible to deformation during machining. This deformation can adversely affect the geometric integrity and machining precision of the component, including dimensional accuracy, shape accuracy, and positional accuracy. Controlling the deformation of thin-walled components has thus become a critical research focus in recent years. This paper reviews the latest developments in the types of machining deformation, deformation mechanisms, and deformation control strategies for thin-walled components, aiming to equip readers with dynamic approaches for achieving high efficiency and precision in thin-walled component machining. The first section provides an overview of the definition, classification, and factors affecting the machining accuracy of thin-walled components. The second section discusses the mechanisms behind the deformation of thin-walled components, which result from a combination of multiple factors, including deformation caused by cutting forces, cutting temperature, residual stress, fixturing, and machining chatter. The third section reviews several methods for controlling deformation, including adaptive machining and error compensation, stability lobe diagrams and chatter suppression, deformation prediction and control, and energy field-assisted machining. These methods allow for the control and prevention of thin-walled component deformation before, during, and after machining. Finally, the paper summarizes the current challenges in thin-walled component machining and outlines future development trends. The research content and methods introduced in this paper, including theoretical analysis, experimental validation, and simulation analysis,

Flexible composites-based piezoelectric nanogenerator (PENG) with low cost, stable properties and sensitivity to mechanical deformation is highly suitable for constructing a new self-powered perception layer in distributed electrical transmission power lines, which has the potential to reduce labor maintenance costs and improve sensing recognition accuracy. However, the lower output performance of PENG makes it difficult to integrate with energy management circuit and signal recognition system. Herein, we propose a enhanced output performance of composites-based PENG by designing piezoelectric fillers, where BCZT@Ag nanoparticles grow on the surface of BCZT fibers to form a Bracnch heterostructure. The PENG prepared by this new filler exhibits significantly enhanced output of 96.4 V and 15.52 µA, which are about 3.2 and 6.5 times higher than those of PENG without specific design, benefiting from improved charge transport mechanism and induced-polarization. Moreover, a intelligent Power IoTs system through the synergistic integration of this high-performance PENG and learning-assisted data analytics has been constructed, which enables accurate self-powered real-time monitoring of abnormal vibration states in transmission power lines to avoid rupture accident. This work not only provides an effective strategy to enhance the performance of PENG but also offers a new solution for the safe operation in power grid. © 2025, The Authors. All rights reserved.

Addendum to “Fast Iterative-Interpolated DFT Phasor Estimator Considering Out-of-Band Interference”

In the above article [1] , the adopted i-IpDFT estimator was implemented strictly according to the pseudocodes reported in [2] , i.e., Algorithms 1 and 2. However, a more detailed implementation of the i-IpDFT estimator is reported in [3] . One crucial detail missing in [2] but reported in [3] is: for q > 1 every time the e-IpDFT is called, line 3 of Algorithm 1 in [3] (corresponding to line 2 of Algorithm 1 in [2] ) should be skipped, and the estimates of the previous iteration should be directly used in the spectral interference compensation routine in line 5 of Algorithm 1 in [3] (corresponding to line 4 of Algorithm 1 in [2] ). This crucial detail not only ensures that the i-IpDFT estimator has a faster convergence rate but also provides higher estimation accuracy.

In view of the current high-speed power line carrier technology (HPLC) lack of an effective monitoring system, this paper proposed a design scheme of an HPLC operation monitoring system based on noise decomposition. The system adopts modular design, including signal acquisition, information transmission and noise decomposition. The signal acquisition module adopts capacitive coupling technology, which considers the convenience and accuracy of the system monitoring performance. The information transmission module adopts wireless transmission technology to meet the needs of HPLC channel monitoring. The noise decomposition module completes the decomposition and identification of noise by constructing a feature library, and realizes the quantitative evaluation of on-site noise. The proposed scheme is of technical reference for improving the portability and accuracy of the monitoring system.

The load-characteristic charging of EVs and the power of distributed PVs have lately received great attention for car and electric industry due to their energy conservation and environmental friendliness. However, the disordered charging of EVs together with the distributed photovoltaic has made it challenging to meet the energy efficiency and electric quality. In an effort to overcome this challenge, the Monte Carlo method is adopted to calculate the charging load of EVs both in ordered and disordered way and the mathematical model of photovoltaic cell power is established. The reasonable dispatching in EVs and PVs is detailed demonstrated using MATLAB language, with certain day load in the area under the different circumstances. The proposed load characteristic method opens the door to research in the field of EVs and PVs, greatly enhancing the energy-using efficiency and the electric quality. © 2019 IEEE.

Radio Frequency Identification (RFID) technology has been rapidly developed in recent years. Electronic tag constitutes an important part of RFID system. This paper presents the design verification and test techniques suitable for UHF (Ultra High Frequency) RFID passive tag, which can meet the designers' demand for verification and test. Then, the IC baseband circuit test platform based on field programmable gate array is proposed. The platform can be used to verify the function of baseband circuit at design stage. It can also help designers with HDL (Hardware Description Language) code commissioning, so as to improve the reliability of circuit design, which can greatly improve the success rate of tape-out in practical applications. With regard to IC RF parameter test, this paper comes up with a low-cost test technical solution based on the commercially available card reader and the adjustable attenuator, which can be used to accurately measure the RF parameters such as IC sensitivity and input impedance without special RFID equipment, so as to guide the design of antenna and RFID. Based on the above-mentioned test scheme, the UHF RFID Tag IC that has been developed and taped out is tested in this paper. © 2019 IEEE.

Currently, most researches on anti-electricity stealing technologies have not combined seasonal power consumption features, social and economic information for electric stealing situational warnings, and cannot effectively solve the problem of large workload and low accuracy in manual anti-electricity stealing monitoring. In addition, they cannot provide reliable technical support for front-line staff of electricity consumption inspection and anti-electricity stealing to accurately and efficiently carry out anti-electricity stealing analysis and investigation work. In view of this situation, this paper proposes a multi-dimensional intelligent deduction and risk early warning evaluation method of electricity stealing situation. © 2020 ACM.
