基于ASP.NET的课目考试平台的设计与实现

由于传统的改卷模式效率低下,重复性工作较多。为解决这一问题,提出一种基于ASP.NET的课目考试平台,该平台采用SQL server数据库存储试题库,运用ASP.NET和C#搭建平台结构,以B/S的形式展示考试界面,界面操作简单,零安装,方便学生和教师操作。目前该平台已完成设计并且投入到实际教学中运用,经过调查发现,平台运用后明显减少教师重复性工作。     

考场环境下考生视线估计方法

考生异常行为的监测容易使监考人员产生视觉疲劳。借鉴监考人员发现异常的过程,提出一种可用于考场异常行为分析的视线估计模型。为了减少图像中视线的信息损失,采用注视向量表示视线的大小和方向。该模型分为生成器、视线合成模块、鉴别器,先将考生头部图像输入生成器生成注视向量,再将头部位置和注视位置输入到合成模块得到真实注视向量。将头部图像与上述所得的两种向量输入鉴别器中,其生成对抗模式达到最优时,可得到生成真实值的生成器模型。实验结果表明,在多个考场环境中,该方法的性能优于所对比的几种方法。其中与Lian等人方法相比AUC（Area Under Curve）提高了2.6%,Ang（Angular error）和Dist（Euclidean distance）分别有效降低了20.3%和8.0%。     

Non-destructive testing and pre-warning analysis on the quality of bolt support in deep roadways of mining districts

The bolt support quality of coal roadways is one of the important factors for the efficiency and security of coal production. By means of a self-developed technique and equipment of random non-destructive testing, non-destructive detection and pre-warning analysis on the quality of bolt support in deep roadways of mining districts were performed in a number of mining areas. The measured data were obtained in the detection instances of abnormal in-situ stress and support invalidation etc. The corresponding relation between axial bolt load variation and roadway surrounding rock deformation and stability was summarized in different mining service stages. Pre-warning technology of roadway surrounding rock stability is proposed based on the detection of axial bolt load. Meanwhile, pre-warning indicators of axial bolt load in different mining service stages are offered and some successful pre-warning cases are also illustrated.The research results show that the change rules of axial bolt load in different mining service stages are quite similar in different mining areas. The change of axial bolt load is in accord with the adjustment of surrounding rock stress, which can consequently reflect the deformation and stability state of roadway surrounding rock. Through the detection of axial bolt load in different sections of roadways, the status of real-time bolt support quality can be reflected; meanwhile, the rationality of bolt support design can be evaluated which provides reference for bolting parameters optimization.     

利用充电法检测桩基础钢筋笼长度

桩身钢筋笼长度是影响桩身受力性能的一个重要因素,但桩基础施工完毕后,属于隐蔽工程,其长度是否符合设计要求却难以验证。针对桩基中钢筋笼长度检测难的问题,探索一种能定量或半定量检测桩体中钢筋笼的长度、且不需要进行破坏性开挖的无损检测技术是关键。本文简述了利用高密度电法测量系统进行钢筋笼长度的无损检测（充电法检测）的基本原理及其方法,并结合实际工程实例予以说明。

Ultrasonic technique for measuring porosity of plasma-sprayed alumina coatings

Porosity is an important factor in plasma-sprayed coatings, especially ceramic coatings. Excessive poros-ity can adversely affect the performance of the coated component in various ways. An ultrasonic nonde-structive measurement technique has been developed to measure porosity in plasma-sprayed alumina coatings. The technique is generic and can be extended to other ceramic coating systems. To test the tech-nique, freestanding alumina coatings with varying levels of porosity were fabricated via plasma spray. Samples with varying porosity, obtained through innovative fabrication techniques, were used to gener-ate a calibration curve. The ultrasonic velocity in the low-frequency range was found to be dependent on the density of freestanding coatings (measured via Archimedian techniques). This dependence is the basis of the development of a technique to measure the density of coatings.
