Experimental Research on Braking Feedback and Taxiing Feedback System of New Energy Vehicles

This paper took a new energy vehicle feedback system as the research object, aiming to study the energy recovery law of the new energy vehicle under braking feedback and taxiing feedback conditions. Firstly, the braking energy feedback control strategy and different forms of taxiing energy feedback were studied. Then the integration and application of braking energy recovery system were carried out on a pure electric bus and a hybrid electric bus, with each vehicle model corresponding to different integration and test schemes, which provided a guarantee for the relevant test of real vehicle environments. Finally, relevant vehicle experiments were carried out to test the impact of superposition and coordination strategies on the contribution rate of braking energy recovery under a typical Chinese city bus circle and compared the difference in vehicle energy consumption with and without taxi feedback strategy. The test results showed that the coordinated braking energy recovery control strategy can make more effective use of the maximum torque that can be fed back by the motor, and the fuel consumption of the taxiing feedback mode was lower than that of the no taxiing feedback mode under different driving conditions.

Information technology of visualization for technological processes for research modes of functioning of complex technological systems

The development of a mathematical model of a technical system based on the means of discrete-continuous networks and taking into account the interaction with a multimedia platform is presented. The efficiency of the process for visualizing the functioning of the complex technical system is increased by implementing the interaction of the modeling environment with the Unity platform in the feedback mode. The experiments linked to the integration of the DC-Net simulation software environment with the Unity cross-platform development environment are implemented. An example of developing the model of a technical system in the DC-Net environment and an example of developing a process for visualizing the functioning of a corresponding technical system based on the Unity platform are presented. The fundamental suitability of using the integration of various information technologies linked with various software environments has been confirmed.

Real-time ghost imaging of Bell-nonlocal entanglement between a photon and a quantum memory

Certification of nonlocality of quantum mechanics is an important fundamental test that typically requires prolonged data collection and is only revealed in an in-depth analysis. These features are often particularly exposed in hybrid systems, such as interfaces between light and atomic ensembles. Certification of entanglement from images acquired with single-photon camera can mitigate this issue by exploiting multiplexed photon generation. Here we demonstrate this feature in a quantum memory (QM) operating in a real-time feedback mode. Through spatially-multimode spin-wave storage the QM enables operation of the real-time ghost imaging (GI) protocol. By properly preparing the spatial phase of light emitted by the atoms we enable observation of Bell-type nonlocality from a single image acquired in the far field as witnessed by the Bell parameter of S=2.227±0.007>2. Our results are an important step towards fast and efficient utilization of multimode quantum memories both in protocols and in fundamental tests.

NMDA receptor signalling controls R-type calcium channel levels at the neuronal synapse

Regulation of extracellular Ca++ influx by neuronal activity is a key mechanism underlying synaptic plasticity. At the neuronal synapse, activity-dependent Ca++ entry involves NMDA-type glutamate receptors (NMDARs) and voltage-gated calcium channels (VGCCs); the relationship between NMDARs and VGCCs, however, is poorly understood. Here, I report that neuronal activity specifically regulates synaptic levels of R-type VGCCs through synaptic NMDAR signalling and protein translation. This finding reveals a link between two key neuronal signalling pathways, suggesting a feedback mode for regulation of Ca++ signalling at the synapse.

DIAPHRAGMATIC BREATHING IN BIOLOGICAL FEEDBACK MODE FOR CORRECTION OF THE PSYCHOPHYSIOLOGICAL STATE IN MEDICAL STUDENTS

The aim: The current study aimed to examine the possibility of correction of the psychophysiological state of the undergraduate students by diaphragmatic breathing sessions in the biological feedback mode utilizing heart rate variability. Materials and methods: The study enrolled 86 students 18 to 20 years old. Assessment of the functional state of the ANS was performed bycardiointervalography (CIG) and analysis of the spectral indices of HRV by the hardware-software complex “Cardiolab” (КAI Medica, Ukraine). A complex assessment of the autonomic homeostasis was performed using IARS calculated by a special algorithm. Assessment of the psychophysiological state of students was performed by questionnaires. Results: Among the examined population, 45% of students were in the state of satisfactory adaptation, 43% – in the state of functional tension, and 12% – in the state of unsatisfactory adaptation. Students with poor level of adaptation and depletion of regulatory mechanisms had higher heart rate, systolic and diastolic pressure, and RR compared to the students in the state of satisfactory and strained adaptation. Conclusions: The findings suggest that the average intensity of psychosomatic complaints has significant differences between groups with varying degrees of tension of regulatory mechanisms.
