In this paper, an active resonant rectifier based on the synchronous rectification is proposed. this active rectification not only replaces the passive diode, but also aims to reduce the burden of the previous post-processing or techniques applied in inverter or resonant network, or even completely eliminate it. In order to cope with a controllability of output power regulation, a topology with a variable resonant capacitor cell is proposed. the proposed variable resonant capacitor cell can be applied to Class E rectifier, and even other single ended resonant converters. the design methodology using an analytical normalized model is introduced to help intuitive understanding of the proposed topology. A design example is verified with a prototype board. Detailed equations and explanation on the design are explained withthe experimental results.

this study investigates methods for detecting and monitoring the attention span of autistic children in real-time, withthe goal of improving learning outcomes. the study involved monitoring the movements and reactions of a group of autistic children during various activities, using specialized sensors and software to capture and analyze data related to their attention span. the results showed that the attention span of autistic children varied significantly across different activities and stimuli, and certain types of games and learning exercises were more effective at capturing and maintaining their attention than others. the attention span of autistic children also tended to improve gradually over time, particularly when they were engaged in activities that were interesting and stimulating. these findings have important implications for the design of effective interventions and learning activities for autistic children, and highlight the importance of personalized and evidence-based approaches for improving attention span and learning outcomes.

In order to solve the problem of polarization effect and electrode corrosion in electrode conductivity sensor, a dual-excitation type nine-electrode conductivity sensor is optimized and designed by analyzing the equivalent measurement physical model of electrode conductivity sensor, establishing a theoretical calculation model of conductivity and output voltage, and supplemented by finite element analysis. the structure of the nine-electrode conductivity sensor was designed, and the corresponding calibration and test tests were carried out. the test results show that the nine-electrode conductivity sensor has excellent performance in eliminating polarization effect and reducing proximity effect, and the accuracy can reach ±0.001ms/cm. the measuring range is wide, and the measurement range is between 20mS/cm∼60mS/cm, which verifies the rationality of the structure. this structure can effectively improve the measurement accuracy and expand the measurement range, providing a new solution for researchers to measure the conductivity of seawater with high precision.

the paper proposes an approach to and solves the problem of controlling a robot by using neural interface technology, describes the general scheme and working principle of the main idea of non-invasive neural interface control of a robot using the original convolutional neural network. the authors describe the principles of an original convolutional neural network and an approach to the modern network design, present a model of a one-dimensional convolutional network based on the principles of a human inner ear. the structure of a software package is proposed. the results of a comparison of algorithms for the analysis of human brain evoked potentials used in the design of brain-computer interfaces are presented. the authors used the Fourier transform algorithm and the multidimensional synchronization index (MSI) algorithm in various modifications to perform the experiment. Analysis of the initial signal, the accumulated evoked potential, in addition to the accumulated evoked potential spectrum were proposed as variations. Linear correlation was also evaluated with analysis using a user-derived reference signal sample and various variations of wavelet filtering. In addition, model signals, which were a combination of white noise and a harmonic oscillation simulating a stable visual evoked potential, were used. the best results (error rate <10%) with an analysis time of 3 s were obtained for the MSI of the original signal, MSI withthe Fourier transform. Also in this list, there is a MSI where the wavelet filtering result of coherent accumulation was used as an etalon, a linear correlation coefficient. In a MSI the evoked potential, recovered after the wavelet transform, was used as an etalon.

No doubt complementary metal oxide semiconductor (CMOS) is one of the promising technology for circuit design but CMOS comes with its own flaws. the upcoming technologies maybe in used to improvise the comprehensive efficiency of the circuits and systems. In this regard, an alternative computing platform quantum-dot cellular automata (QCA) has been a lesser known yet effective nanoscale technology that has emerged with its own set of qualities like being faster, having denser circuit, erase and ultra-low power consumption. It is becoming quite popular in modern time and is compressible to the existing technologies of today. In this paper, block coding 4B/5B is implemented in QCA technology and verified the functionality using QCA designer tool.
