查询词典 hadamard criterion

In the non dimensioned time domain,the generalized quadratic performance criterion of error state transits into the optimal problem of structural parameters,thus gets an optimal parameter system—optimal damping control system with big margin for stability,little number for oscillation,small overshoot,and small setting time.

在无量纲时域中，把状态误差的广义二次型性能指标转换成结构参数的优化问题，从而得到一种稳定裕度大、振荡次数少、超调小、调节时间短的最佳参数系统——最佳阻尼控制系统。

在此基础上，论文利用一种基于几何和人眼视觉空间的混合误差判别准则对地表网格模型进行了一定的简化，并以此来降低计算机的处理数据量，达到快速的场景生成。

A model for logging interpretation of glutenite reservoirs with large differences between lithology and physical property was not simply based on the criterion of siltstone reservoirs with similar lithology and physical property to be used.

对于岩性、物性差异较大的砂砾岩储层，测井解释模型的建立不能套用岩性物性相近的较为简单的砂泥岩储层标准。

Its characteristics are two NOTs and four SELFs: the teacher will not tell learning targets and will not give the answers to the questions directly; the students are supposed to sense with their own hearts, to judge by their own criterion, to innovate with their own thoughts, to express in their own words.

非指示性教学的理念与2001年颁布的基础教育课程改革的基本理念存在许多一致之处，因而成为符合新课程改革精神的具体的教学模式，在新课程背景下得到了教育学界的探讨和研究，引起了较大的反响。

A great lot of facts indicate that the navigation performance of ships is good in quiet water, but not always good in waves. Whether the performance of ships is superior or inferior mainly depends on their performance in waves. The seakeeping of ships has become an important criterion which can scale the navigation performance of ships.

大量事实表明，一艘在静水中航行性能优良的船舶，在波浪上的航行性能并不一定是优良的，船舶性能的优劣，主要看它在实际海洋环境中的性能，船舶耐波性的好坏已成为衡量现代化船舶航行性能的重要衡准之一。

A new multi-sensor optimal information fusion criterion weighted by scalars is presented in the linear minimum variance sense.

引 言 信息融合Kalman滤波理论在机动目标的组合导航中具有广泛应用。

This paper proposes a novel joint iterative channel estimation and symbol detection algorithm based on MMSE criterion for MIMO-OFDM systems.

摘要该文提出了一种MIMO-OFDM系统中基于MMSE准则的联合迭代信道估计和符号检测算法。

For example, line of Beijing, Shanghai added to be mixed afternoon respectively airliner of pass the night, and boat of Shenzhen pass the night sound of class criterion You Bo Boeing of 777 executive instead 757 carry out.

Furthermore, the algorithm exhibits robuster in the situation that the object is partially occluded, rotated and shape distorted. A vision-based human motion recognition method is introduced in this paper. A modified shape context method named area-based shape context is used to describe the shape. Then continuous hidden markov models are built to model the human motions, and Bayesian criterion is used to classify them.

本文的行为识别算法是建立在对人体行为观测的基础上的，用一种改进的基于人体区域的形状上下文技术表示人体轮廓形状，通过对训练样本集进行学习，利用最佳状态数估计法建立连续隐马尔可夫模型之后，利用贝叶斯判别准则，实现了对人体行为如走、跑、双脚合拢跳跃、单脚跳跃和侧向跳跃五种行为的识别。
