Excel 2010高级筛选功能在学籍管理中的应用

通过对Excel 2010"数据"选项卡"排序与筛选"组中的"高级"命令的分析,科学设置高级筛选中条件区域,能够将Excel 2010高级筛选功能发挥到极致,弥补目前Excel 2010教材中对高级筛选功能简单化的不足,有效地解决在学籍管理中遇到的各种关于信息筛选方面的问题。     

浅谈Excel高级筛选

数据的筛选是Excel的强大功能之一.筛选是将不满足的条件数据暂时隐藏起来,只显示符合条件的数据.Excel 中的筛选分为自动筛选和高级筛选,用户一般使用自动筛选更多,因为自动筛选更方便、直观,而高级筛选前要设置条件区域,使用起来更不方便.     

Excel2003高级筛选实例剖析

利用Excel 2003的高级筛选功能,可以从数据清单中选出符合某些复杂条件的记录,操作过程简单,大大提高工作效率。     

在EXCEL中快速选定单元格区域

在Excel中选定单元格区域似乎是一个很基本的操作,只要按下鼠标拖动,就可以完成单元格区域的选择了。可是,如果我们选择的是一个很大的区域,如A1:F13456,或者是要同时选中几个这样区域?或者我们要选中的是所有含有条件公式的单元格?或者要选中是自动筛选后的那些屏幕上显示的单元格?如此等等,决不是简单的鼠标拖拉就可以直接完成的。不过也不用担心,在Excel中,快速选定单元格区域还是有窍门的。     

复杂条件一网筛尽 Excel高级筛选技巧

Excel中的“自动筛选”功能大家也许并不陌生,对于条件简单的筛选操作,它基本可以应付。但是,最后符合条件的结果只能显示在原有的数据表格中,不符合条件的将自动隐藏。若要筛选含有指定关键字的记录,并且将结果显示在两个表中进行数据比对或其他操作,“自动筛选”就有些捉襟见肘了。“傻瓜相机”毕竟功能有限,那么就让我们来试试“高级相机”吧!熟练运用“高级筛选”,无论条件多么复杂,都能一网筛尽。人力资源部的小李最近在做员工表格统计时,就尝到了甜头。     

条件格式让成绩更出“彩”

2012/17PLUS看了2012年17期26页《用筛选让成绩出"彩"》一文,本人认为文中使用"自定义筛选"与"高级筛选"让成绩出"彩"的方法略显复杂。文中说若要查看三门课均大于90分的同学无法通过设置条件格式来达到,显然,这是作者还未认识到条件格式的精妙所致。就此问题,对于不同版本的Excel,我们同样可以通过设置条件格式来达到此目的。     

用高级筛选做个多条件查询界面

公司有—份合同记录表经常需要按多种条件在表中查找符合条件的所有记录。众所周知，使用高级筛选可以轻松实现复杂条件的查找，但每次都设置条件区和高级筛选也很麻烦。于是笔者决定用高级筛选做个简单、易懂的快速查询界面，以解决平时的多条件查询要求。     

轻松掌握Excel2007数据筛选

数据筛选是Excel2007重要功能,本文以简单实例介绍了自动筛选和高级筛选的使用方法。     

Excel答案非唯一考核点自动阅卷技术分析

Excel操作题自动阅卷,一般通过VBA技术实现自动阅卷,然而现有Excel阅卷方法在处理答案非唯一考核点时容易出现阅卷错误.针对Excel操作最可能出现答案非唯一的两种考核点,即条件区域的定义和函数的使用,通过举例,介绍有助于准确阅卷的几种方法,包括排序法、等效引用法、列举法、特殊参数验证法、等效条件法.实践证明,使用这些方法能够减少答案非唯一考核点自动阅卷过程中出现误判、漏判,提高了自动阋卷的准确性.     

妙用删除重复项

要在数以万计的数据中找出并删除重复记录,以往一般采用高级筛选来完成,Excel 2007新增了一个“删除重复项”按钮,操作更加简单、灵活。比如我们要在600多名考生考号安排表中找出是否有     

Behavior and Instantiation of High–Level Net Processes

Processes for high-level nets N are often defined as processes of the low-level net Flat(N) which is obtained from N via the well-known flattening construction. This low-level notion of processes for high-level nets, however, is not really adequate, because the high-level structure is completely lost. For this reason we have introduced in a previous paper a new notion of high-level net processes for high-level nets which captures the high-level structure. The key notion is a high-level occurrence net K, which generalizes the well-known notion of occurrence nets from low-level to high-level nets. In contrast to the low-level case we consider high-level occurrence nets together with a set of initial markings of the input places. In this paper we show under which conditions the behavior of low-level occurrence nets and processes can be generalized to the high-level case. A key notion is the instantiation L of a high-level occurrence net K, where L is a low-level subnet of the flattening Flat(K) with isomorphic net structures of L and K. One of our main results characterizes under which conditions a high-level occurrence net - and hence a high-level net process - has unique and nonoverlapping instantiations and can be represented by the union of all its instantiations.     

A spatially distributed risk screening tool to assess climate and land use change impacts on water-related ecosystem services

To support the implementation of the European Water Framework Directive (WFD), and as part of a tiered approach to prioritise detailed modelling, a high-level screening methodology has been developed to assess the vulnerability of water-related ecosystem services (ES) to future change. The approach incorporates a range of spatially distributed scenarios of land use and climate, which are used as inputs to a qualitative risk assessment model underpinned by expert opinion. The method makes use of widely available datasets and provides a structured way of capturing and “codifying” expert knowledge, as well as for assessing the degree of consensus between different expert groups. The range of model output reflects uncertainty in both the expert-derived assumptions and the climate & land use simulations considered. The approach has been developed in collaboration with the Scottish Environment Protection Agency (SEPA) and applied in Scotland to support the second cycle of River Basin Management Planning.     

基于强化语义的中文广告文本识别技术研究

互联网是广告推广的重要媒介,但是低质、诈骗、违法等违规广告也大量充斥其中,严重污染网络空间,因此,实现恶意广告的有效甄别对构建安全清朗的网络环境意义重大。针对各类违法违规中文广告内容的识别需求,利用Bert(bidirectional encoder representation from transformers)和Word2vec分别提取文本字粒度和词粒度嵌入特征,使用CNN(convolutional neural networks)网络对Bert高层特征做深层抽取,同时将词粒度特征向量输入到双向LSTM(long short-term memory)网络提取全局语义,并采用Attention机制对语义特征强化,将强化特征和Bert字粒度特征进行融合,充分利用动态词向量和静态词向量的语义表征优势,提出一种基于强化语义的中文广告识别模型CARES(Chinese advertisement text recognition based on enhanced semantic)。在真实的社交聊天文本数据集上的实验表明,与使用卷积神经网络、循环神经网络等文本分类模型相比,CARES模型分类性能最优,能更加精确识别社交聊天文本中的广告内容,模型识别的正确率达到97.73%。     

A Low-Level Analysis Library for Architecture Recovery

We discuss low-level program analyses that are reusable in many high-level analyses for architecture recovery. They include both program structure analyses known from compiler front-ends and data-flow analyses. In general, high-level analyses use the low-level results only partially. We argue that it is necessary to perform the low-level analyses completely, though. To deal with large systems and to adapt to different high-level analyses, it is, however, necessary to control the low-level analyses' precision and scope.     

一种基于图像高层语义信息的图像检索方法

由于基于图像高层语义信息的图像检索与传统的图像特征匹配检索相比，在检索的准确性、结果相关性以及降低误检率等方面具有明显的优势，因此高效的图像检索方法应该充分利用图像蕴涵的高层语义信息。为了利用图像的高层语义信息来进行图像检索，在深入研究图像高层语义的低层特征描述的基础上，提出了图像语义的层次划分，并对每个高层语义层提出了语义抽取和检索算法。实验结果表明，该检索算法可以有效地对图像高层语义信息进行提取，并可作为新型高效图像检索系统的一个模型。     

High-level testing and example-directed development of software specifications

A testing-based approach for constructing and refining very high-level software functionality representations such as intentions, natural language assertions, and formal specifications is presented and applied to a standard line-editing problem as an illustration. The approach involves the use of specification-based (black-box) test-case generation strategies, high-level specification formalisms, redundant or parallel development and cross-validation, and a logic programming support environment. Test-case reference sets are used as software functionality representations for the purposes of cross-validating two distinct high-level representations, and identifying ambiguities and omissions in those representations. In fact, we propose the use of successive refinements of such test reference sets as the authoritative specification throughout the software development process. Potential benefits of the approach include improvements in user/ designer communication over all life cycle phases, and an increase in the quality of specifications and designs.     

A structured approach to language design

This report is an attempt at systematizing a set of ground rules for high-level language design. It recommends the use of a hierarchical semantic model schema. HGL, in a step by step, top-down approach imposing more and more structure on the language components as the design becomes solidified. The approach is demonstrated by showing the stepwise design of the high-level language, GRAAL. The method recommended is divided into three major phases. The first is an informal one. The second is encoding the language components into a very high-level model. This high-level design allows a redesign of language components before they have been specified at too detailed a level. The third phase is to design the compiler in HGL using the final language design.     

Linking simulation with formal verification at a higher level

We use simulation to bridge the gap between specification and formal verification of high-level models and simulation of RTL models. The authors apply their practical, two-phase procedure for defining the refinement map to the Alpha 21364 multiprocessing hardware. The methodology and tools they present can improve simulation coverage. Our technique verifies that a hardware design described at the RTL is a correct implementation of an algorithm-level, executable formal specification. We use a high-level formal specification as the basis for monitoring functional correctness, measuring simulation coverage, and generating test cases.
