Background: The novel coronavirus pandemic has not only affected people's health. The pandemic has also affected their social life and work. For all the reasons mentioned, international trade has suffered and is still in the process of recovery. Objective: Especially in the semiconductor industry, many manufacturers postponed their deliveries to future periods and this triggered the chip crisis. Many hightech industries, including the automotive industry, were deeply affected by the consequences of the crisis, with factories halting or slowing down production. despite the shortage of chip stocks, Nuvoton has a large amount of Microcontroller Units (MCUs), but due to the shortage of resources, education and libraries, software developers have not been able to integrate their products in a limited time. Methods: In this paper, the Nuvoton Education Board has presented 20 common examples for embedded software developers and beginners. results: The PCB is designed considering all modules connected to separate General Purpose Input Output (GPIO) pins to make multiple module examples without changing the peripherals and pin configuration of the MCU. Clock configuration has been simplified and unnecessary details have been meticulously removed to make the examples easily understandable. Nuvoton NuMaker M263KI V1.3 was added on the designed PCB. Conclusion: The PCB contains almost all the necessary electronics to learn embedded software and use Nuvoton MCUs in industrial projects. The board is supported with user interfaces and printed documentation. The codes are explained with command lines to teach users even small details. A patent application has been filed for the proposed education board. © 2024 Bentham Science Publishers.

For the past decades, the density of drAM has been remarkably increased by making access transistors and capacitors smaller in size per unit area. However, shrinking devices far beyond the 10 nm process node increasingly poses process and reliability challenges. As Flash technology made a pivotal and successful innovation via 3d NANd, drAM technology may also adopt vertical stacking memory cells. Vertically stacked drAM (VS-drAM) continues to increase bit density on a die by increasing the number of layers along with reducing the size of the transistor. In this paper, the opportunities and challenges of VS-drAM are discussed. © 2023 JSAP.

Coal rock fractures play a vital role as key channels for gas migration and storage in the exploration and development of coalbed methane. The characteristics of these fractures, such as porosity distribution, specific surface area, and connectivity, directly impact the adsorption, diffusion, and permeability behaviors of coal reservoirs. Therefore, a detailed analysis of coal rock fracture characteristics is vital in assessing the extractability of coalbed methane and during its exploration and development process. Currently, techniques like imaging logging, seismic detection, and micro-CT are employed for characterizing and studying fractures at various scales. Among these, high-resolution non-destructive CT scanning technology, by constructing three-dimensional data models of core samples, enables a quantitative analysis of fracture distribution features and size parameters. Traditional digital image processing methods, such as threshold segmentation and binary segmentation, though advantageous in computational speed, have limitations in the accuracy of fracture identification. With the advancement of artificial intelligence technology, deep learning-based image processing techniques have increasingly become significant tools for fracture detection due to their powerful feature extraction capabilities. This study conducted micrometer-level CT scanning experiments on coal rock samples, using CT image processing technology to construct a digitalized coal rock core model. deep learning methods were applied for precise fracture identification, establishing an appropriate deep learning architecture and optimized parameters for coal rock fracture recognition. Furthermore, this paper provides a detailed quantitative characterization of the precisely identified fractures, offering robust technical support for the exploration and development of coalbed methane.

Not only is superheated steam still widely used as a primary working fluid for driving various types of power generation systems, but it is also an essential intermediary substance for reforming fossil fuels. This study was conducted to extend the applicable range of the ideal gas law for calculating superheated steam properties by incorporating the compressibility factor. The compressibility factor was determined by evaluating the second Virial coefficient, and it was confirmed that this study is applicable up to the pressure of 8.0 MPa of superheated steam, which is a significant achievement. Additionally, the redlich-Kwong equation was theoretically analyzed for the first time and its theoretical basis was established, which was not achieved even by the original authors. This thorough analysis of the redlich-Kwong equation may serve as a new starting point for developing a new equation of state for gases and vapors.

dolomitization is the main geological process that turn pelletoid into dolomites. How does dolomitization convert pelletoid into dolomites? Why do dolomites have different structures and crystals? This paper mainly answers these two questions. Based on core, cast thin sections, physical property and mercury intrusion, the Pelletoid types are first determined. Secondly, the diagenesis of the Pelletoid is comprehensively recognized, including the diagenetic types, diagenetic environment and diagenetic product. Finally, the dolomitization model of Pelletoid is established. There are four types dolomite in Arab C formation in BH oilfield. The Arab C Formation was in a tidal flat environment, in which facies include supratidal, intertidal and subtidal. different facies have different water energy, lithology, exposure probability and time, as a result, the diagenesis such as gypsification, dolomitization, dissolution and cementation in different area vary greatly. That’s why there are four type of dolomite even the primitive particles are the same pelletoids. The pelletoids were mainly in the intertidal facies, subtidal facies with relatively high energy could also developed. Intertidal facies was easy to exposure, and gypsification and dolomitization was intense in penecontemporaneous stage. due to the environment difference, response to sea level fluctuation and exposure time, the diagenesis, especially the extent of dolomitazition is different. As a result, the dolomite has different character in structure and crystal. © (2023) by the European Association of Geoscientists & Engineers (EAGE). All rights reserved.

As an efficient and intelligent means of knowledge organization, knowledge graph has become the core force driving the development of artificial intelligence. Hydraulic fracturing is an important measure for increasing production and injection in oil and gas fields, with complex design processes and numerous influencing factors. In order to achieve rapid and accurate optimization of fracturing plan, this paper proposes a method for optimizing fracturing plan based on knowledge graph. By combing the system of fracturing domain knowledge, fracturing knowledge graph is constructed. Extracting characteristic parameters describing the geological engineering double sweet spot in multiple dimensions and multiple scales, and showing the characteristic parameter-related entities, relationships, and attributes as vectors via graph embedding technique. Integrate expert knowledge with artificial intelligence to build a fracturing effect prediction model and optimize the fracturing plan. In this study, more than 500 fracturing oil wells in a tight sandstone block are taken as objects to build a knowledge graph. Based on well test and production test data and historical production, this study predicts the fracturing stimulation effect and optimizes the fracturing engineering parameters. The calculation results indicate that factors such as reservoir thickness, oil saturation, number of fracture clusters, and half length of fractures have a significant impact on the fracturing effect. The coincidence rate between the predicted capacity of production and the actual capacity of production is over 91%, and the efficiency of fracturing plan design is increased by more than 20 times. The research results can provide scientific basis for predicting fracturing effects and optimizing fracturing engineering parameters, greatly improving the efficiency and quality of fracturing design, and improving the success rate of fracturing construction. © The Author(s), under exclusive license to Spr

This paper proposes an integrated neural network for joint noise suppression and resolution enhancement of inverse synthetic aperture radar (ISAr) images. Unlike conventional methods that address both challenges separately, we present a unified framework that can address them simultaneously. To achieve this, we first generate a comprehensive dataset of ISAr images for various targets under different conditions using a simulation-based method. Subsequently, we develop separate generative models for noise suppression and resolution enhancement, which are then combined sequentially. This combined network uses a joint optimization strategy in training process, simultaneously updating the weights of the two networks. The proposed integrated network achieved an average peak signal-to-noise ratio and structural similarity index measure of 34.69 dB and 0.95, respectively. It demonstrates that the proposed network effectively achieves both noise suppression and resolution enhancement within a single network.
