基于派生文法的日—蒙动词短语机器翻译研究

本文探索了源语为日语,目标语为蒙古语的动词短语机器翻译系统的实现方式。基于主张日语不活用的派生文法,重新分析日语附加成分。将日语的词干和附加成分转换到蒙古语的词干和附加成分之后,运用蒙古语的语音规则来处理并生成动词短语。在此基础上试做了日—蒙动词短语机器翻译系统。对30篇日文报道的403个动词短语进行测试,取得了95.78% 的正确率。     

AUTOCAD的二次开发中对实体操作功能的设计

如今,CAD（计算机辅助设计）技术已被各制造业广泛应用。而美国的AutoCAD是目前在Windows环境下应用最广泛、使用人数最多的CAD支撑软件。本次设计是在论证了CAD二次开发的可行性并比较了AutoCAD各开发系统的优劣之后,选择Object ARX开发平台,用C／C＋＋对AutoCAD软件进行的二次开发。本系统设计工作共分数据库构建、文件读写、操作功能实现和交互式界面四部分。最终完成的软件是一个具备初步的CAD软件结构、用户接口和操作方式的CAD系统,此软件随AutoCAD的启动自动运行,能够实现“读写文件”和“交互式创建、删除和修改直线实体”等功能。

Tuning the band gap of the CIGS solar buffer layer Cd1-xZnxS (x=0—1) to achieve high efficiency

To evaluate the impact of zinc sulfate (ZnSO4) concentration on the structural properties of the films, Cd1-xZnxS thin films were formed on glass substrates using chemical bath deposition (CBD) in this study. The effect of ZnSO4 precursor concentration on the surface morphology, optical properties, and morphological structure of the Cd1-xZnxS films was investigated. To study the impact of zinc doping content on the performance metrics of Cu(In1-xGax)Se2 (CIGS) cells in the experimental group and to improve the buffer layer thickness, simulations were run using one-dimensional solar cell capacitance simulator (SCAPS-1D) software.     

Blood cell counting based on U-Net++ and YOLOv5

Clinical information about a variety of disorders is available through blood cell counting, which is usually done by manual methods. However, manual methods are complex, time-consuming and susceptible to the subjective experience of inspectors. Although many efforts have been made to develop automated blood cell counting algorithms, the complexity of blood cell distribution and the highly overlapping nature of some red blood cells (RBCs) remain significant challenges that limit the improvement of analytical accuracy. Here, we proposed an end-to-end method for blood cell counting based on deep learning. Firstly, U-Net++ was used to segment the whole blood cell image into several regions of interest (ROI), and each ROI contains only one single cell or multiple overlapping cells. Subsequently, YOLOv5 was used to detect blood cells in each ROI. Specifically, we proposed several strategies, including fine classification of RBCs, adaptive adjustment for non-maximal suppression (NMS) threshold and blood cell morphology constraints to improve the accuracy of detection. Finally, the detection outcomes for each ROI were combined and superimposed. The results show that our method can effectively address the issue of high overlap and precisely segment and detect blood cells, with a 98.18% accuracy rate for blood cell counting.

基于CLG光流算法的云的运动分析与研究

将光流算法应用到云的运动分析中,同时探讨光流变化与云的运动之间的关系.文中采用了局部与全局(CLG)相结合的光流算法分析云的运动.CLG算法同时其备局部光流算法和全局光流算法的优点,利用 CLG光流算法能得到鲁棒而且稠密的云的运动流场.文中首先详细分析了CLG 三种光流算法:空间CLG、时空CLG、非线性CLG光流算法.然后将这三种算法应用到云的运动视频中,并对三种CLG光流算法红云的运动上进行了分析和比较.实验证明,光流算法对于测量云的运动有良好的效果,云的运动与光流之间具有正比关系.     

基于Logistic方法定量判别岩性的研究

判别地层的岩性是地质勘探中的一项最基础性工作。过去,主要靠钻孔岩心编录来判别地层岩性,但对大量快速无岩心钻进的钻孔来讲,此方法就行不通了。针对这种情况,应用Logistic判别法,进行了利用煤田测井曲线数据定量判别岩性的研究工作。研究得出:应用此方法能够自动、定量的判别岩性,达到了研究目的。     

基于FLAC3D的黄土基底排土场稳定分析

我国大型露天煤矿主要分布在西北部的黄土高原地区,以黄土为基底的排土场形成后,黄土基底的工程性质将发生改变并形成演化弱层,演化弱层对排土场边坡稳定性起到控制作用,由于弱层的存在,边坡容易形成"坐落-滑移式"破坏。本次分析是基于强度折减理论,应用FLAC3D对排土场边坡变形进行数值模拟,展现出排土场边坡变形机理。依据数值模拟结果,获得排土场边坡的最危险滑面和多处潜在滑动面。为排土场边坡失稳的预测及防治工作提供科学依据。
