提出了一种新的基于可靠性的多核系统硬实时任务调度方法,并给出定量可靠性模型.首先,每个应用程序都由任务组成,并采用有向无环图建模,显示任务执行周期、任务依赖性及其通信量.其次,提出聚类多数投票方法,在纯大多数投票并行性和纯再执行序列化间进行权衡.聚类多数投票方法是具有确定性定时行为的半并行方法,同时也减少了通信量.然后,提出用于硬实时应用的任务映射策略,试图最小化通信开销和任务图的副本实例,同时保留预定义的可靠性阈值,实现更高的算法性能.仿真结果表明,该方法具有较大的片上网络尺寸、较高的可靠性阈值和接受率,提高了算法的效率.

为解决当前人机交互手势识别方法存在的识别模糊、准确度较低的问题,对人工智能辅助下人机交互隔空手势识别模型展开研究.依据隔空手势识别的处理原理,引入较强的语义反馈与交互通道信息整合机制,实现手势识别模型的架构.基于MCG-Skin数据库,架构颜色分布表达式,经过两个独立高斯模型的合并搭建,分割交互手势.在颜色分布模型中输入经过阈值处理的图像像素点,得到对应的颜色点概率,重建肤色相似度图像.利用离散函数指代灰度范围,归一化手势图像直方图,判定深度直方图的相似度,完成手势跟踪,引入级联式学习器,实现隔空手势识别.仿真结果表明,研究的模型不仅能有效识别出隔空的手势动作,评估指标数值高于95％,具有较高的精准度.

学生数学学习的有效性与他们所持有的数学认识信念有密切的关系.调查结果表明:民族预科生数学认识信念呈现一定的文化特点,各维度的有效性处于中等略偏上水平;在不同维度上存在显著的性别、户籍、学科和层次差异.在民族预科数学教学中,应注意并把握好预科生数学认识信念的特点,有针对性地从教学理念、言行、方式、目标、素材、评价等方面入手来改善民族预科生的数学认识信念.

Due to the most health problems of the building structure damage is cumulative,which is difficult to be detected,the complexity of the actual structure and the ambient noise makes it more difficult to do the structural health monitoring,while the existing method requires a lot of data in the training model,but in practice for the tag data it is very complex.To overcome this problem,by the wireless sensor networks,this paper used the sparse coding to achieve bridge structural health monitoring,and through a large number of unlabeled examples of feature extraction in achieving sparse coding algorithms based on training,it realized the data dimensionality reduction and unlabeled data preprocessing.Secondly,it used the deep learning algorithm to predict the bridge structural health monitoring category,and also used the linear conjugate gradient-based optimization algo-rithm to improve the Hessian optimization,and used the semi definite Gauss-Newton Hessian matrix to replace uncertain Hes-sian matrix,which used the secondary target combinations to achieve deep learning algorithm efficiency.Experimental results show that the depth of the structural safety of the bridge learning detection algorithms achieves a high-precision structural health monitoring of ambient noise levels under sparse coding mentioned.

学生的数学学习习惯是影响其数学学习的重要因素之一.调查发现,预科生在数学学习中的课前预习、课中交流、课后反思的习惯较差;数学学习习惯在性别、文理科以及学习层次上有一定的差异.研究少数民族预科生的数学学习习惯,将有利于对其进行有效的指导和培养.

To solve the problem of imprecise,unsteady and incomplete information in multi label web page recommendation algo-rithms,and that the traditional accurate algorithms are not ideal,the rough set PNN Gauss block based embedded expectation sorting algorithm for multi label web recommendation was presented.For the problem of uncertainty of information,the rough set theory was used to improve the traditional probabilistic neural network,so that it was suitable for dealing with the problem of information uncertainty.To solve the problem of poor coverage and redundant structure in multi label page recommendation using fixed probabilistic neural network,the Gaussian block implantation expectation sorting algorithm was used to construct the merging, adding and deleting operations,improving the prediction accuracy and reducing the computational complexity.The experimental compari-son of the multi label data sets in YAHOO shows the proposed algorithm has higher computational accuracy and efficiency.

This article discusses the assessment method reform of ethnic preparatory undergraduate’s mathematics level, turning from simple to diversified. Basing on the traditional objective closed-book exam, experimental research on the assessment methods, including mathematical consciousness and quality, mathematical thinking composition through curricular and ex-curricular observation is increased, which proves the necessity and importance of objective and overall assessment of ethnic preparatory undergraduate’s mathematics level for undergraduate study. Nowadays, with the initiate and implement of quality-oriented education, it has some practical significance for the reform of ethnic preparatory mathematical education.

There are advantages and disadvantages in the hierarchical teaching of mathematics classroom of secondary vocational schools during the process of the teaching reform. Teachers need to continuously research, explore and develop in teaching practices. Only by this, can the teaching reform play a positive role for the improvement of teaching level.
