Analysis of Coupled Thermal and Electromagnetic Processes in Linear Induction Motors Based on a Three-Dimensional Thermal Model

In a linear induction motor, the paper describes a mathematical representation of interconnected electromechanical and thermal processes. We'll discuss the thermal model's system here, as well as the model's calculation formulas. On each tooth pitch of the LIM, the thermal model consisted of eight control volumes. Model verification was carried out using a model based on the finite element method and collecting experimental data. We established the limits of safe operation for the traction single-sided linear induction motor, considering the variability of heating along the length of two cases: natural cooling and forced cooling. The required air flow values were established for forced cooling. The influence of various factors on heating was investigated for the screw press's arc induction motor.

Interaction of Graphene Oxide Modified with Linear and Branched PEG with Monocytes Isolated from Human Blood

Multiple graphene-based therapeutics have recently been produced, but potential risks connected to nanomaterial-based interactions with immune cells are still unclear. Consequently, investigating the effect of graphene oxide on various populations of immune cells is of utmost importance. PEGylated graphene oxide was discovered in monocytes isolated from human peripheral blood in this study. PEG was successfully attached to the graphene oxide surface, according to We reported that it was successfully attached to the graphene oxide layer. Monocyte viability was examined by GO-PEG on the production of reactive oxygen species, cytokines, phagocytosis, and monocyte viability. Monocytes are able to absorb GO-PEG by monocytes due to a PEG system. The number of GO-PEG nanoparticles per monocyte per monocyte reduced by PEG's branches. In a dose-dependent manner, GO-PEG reduced Escherichia coli's phagocytosis in a concentration-dependent manner. Monocytes secretion of IL-10, which did not appear to be related to their size or PEG configuration, but this action did not correlate with their size or PEG configuration.

Optimal Battery Dispatch Using Finite-Input Set Non-Linear Model Predictive Control: Algorithm Development and Case Study

Battery manufacturing has played a large role in the development of battery manufacturing as a cost-effective energy storage device. In the presence of intermittent renewables such as solar photovoltaic cells, this paper recommends a viable charging and discharging scheme for the battery energy storage device used for economic dispatch and demand/demand balancing services. The test results show that the embedded battery stacking and optimal decision-making algorithm would increase net savings in the sports center's electricity bill as well as CO2 reductions.

Design and Analysis of a Novel Composited Electromagnetic Linear Actuator

paraphrasedoutput:Considering that the conventional moving coil electromagnetic linear actuator has the disadvantages of low force density and a lack of end-passive self-holding capabilities, a novel composited electromagnetic linear actuator is introduced in this work, combining MCELA's performance characteristics with moving iron electromagnetic linear actuator's performance. Firstly, the proposed actuator's geometry and magnetic circuit design scheme are introduced, and the finite element simulation scheme is developed. The CELA's maximum starting force of the CELA with end-passive self-holding capability is 574. 92 N, while the holding force is 229. 25 N, according to the study, although the holding force has been found to be more dependable and precise under various motion modes, and it is also adapted to the CELA's dynamic working conditions of internal combustion engines.

Optical Fiber-Based Monitoring of X-ray Pulse Series from a Linear Accelerator

And if the Cerenkov emission in the transport fiber was also considered contaminated, a sensor with 11 cm of sensitive Ce-doped fiber spliced to rad-hard fluorine-doped optical fiber for the emitted light transfer to the photomultiplier tube was also interesting beam monitoring results. The beam monitoring capabilities of this class of optical fiber was demonstrated for such facilities, as well as the possibility of expanding the dose rate range are discussed based on potential architecture choices such as fiber type, length, or size.

Novel Low Complexity BP Decoding Algorithms for Polar Codes: Simplifying on Non-Linear Operations

During hardware development, the identicality of the belief propagation decoding scheme for polar codes opens up a real possibility of high throughput and low decoding latency. This paper addresses the fact that the BP decoding algorithm introduces high-complexity non-linear operations in the iterative messages update process, namely, exponential BP decoding algorithm and quantization function BP decoding algorithm.

Indirect Electro-Thermal Modelling of Semiconductor Diode Using Non-Linear Behavior of Volt-Ampere Characteristic

The aim of the current paper is the creation of an electrothermal model of semiconductor components using an indirect modelling approach. The approach is based on the incorporation of the component's electrical characteristics considering non-linear behavior of a V-A characteristic. The identification of semiconductor material properties considering non-linear dependencies and semiconductor volume is made in this way. The primary aim of the proposed scheme is to simplify the electro-u2013thermal interaction within finite-element modelling of semiconductor components. Simulation and experiments show that the relative error is within 5% of the actual error.
