数据集集成
本项目集成了多个公开数据集的数据内容,并处理为相同的数据格式(所有数据均被处理为1秒/个的数据样本,并使用fft得到其频域特征)。
样本筛选
可以通过数据集、通道、故障、严重程度对所有样本进行筛选,并选择时域或频域显示。为了显示的流畅性,绘图默认使用下采样方式进行显示(如下采样倍率设为5,则每5个采样点显示1个)。
时域/频谱分析
点击样本右侧的绘制按钮,可以可视化显示样本频谱。前端自动将幅值最大的频率点作为特征频率,并默认使用标尺显示各倍频。特征频率和标尺间隔可通过拖动滑块快速调节,也可通过按钮与输入框精确调节。
跨数据集、故障类型对比
支持同时显示多个数据集、多种不同故障类型的频域/时域信号进行对比,挖掘故障特征。

Alexa Domains
该数据集由前 100 万个网站的 URL 组成。 域名使用 Alexa 流量排名进行排名 是使用浏览行为的组合来确定的 网站上的用户数、唯一身份访问者的数量和网页浏览量。更详细地说,唯一身份访问者是 在给定日期访问网站的唯一用户数, 和 pageviews 是用户 URL 请求的总数 网站。但是,对同一网站的多个请求 在同一天被计为一次综合浏览量。网站 独立访问者和综合浏览量的最高组合 排名最高

Canadian Census
**Overview** The data package provides demographics for Canadian population groups according to multiple location categories: Forward Sortation Areas (FSAs), Census Metropolitan Areas (CMAs) and Census Agglomerations (CAs), Federal Electoral Districts (FEDs), Health Regions (HRs) and provinces. **Description** The data are available through the Canadian Census and the National Household Survey (NHS), separated or combined. The main demographic indicators provided for the population groups, stratified not only by location but also for the majority by demographical and socioeconomic characteristics, are population number, females and males, usual residents and private dwellings. The primary use of the data at the Health Region level is for health surveillance and population health research. Federal and provincial departments of health and human resources, social service agencies, and other types of government agencies use the information to monitor, plan, implement and evaluate programs to improve the health of Canadians and the efficiency of health services. Researchers from various fields use the information to conduct research to improve health. Non-profit health organizations and the media use the health region data to raise awareness about health, an issue of concern to all Canadians. The Census population counts for a particular geographic area representing the number of Canadians whose usual place of residence is in that area, regardless of where they happened to be on Census Day. Also included are any Canadians who were staying in that area on Census Day and who had no usual place of residence elsewhere in Canada, as well as those considered to be 'non-permanent residents'. National Household Survey (NHS) provides demographic data for various levels of geography, including provinces and territories, census metropolitan areas/census agglomerations, census divisions, census subdivisions, census tracts, federal electoral districts and health regions. In order to provide a comprehensive overview of an area, this product presents data from both the NHS and the Census. NHS data topics include immigration and ethnocultural diversity; aboriginal peoples; education and labor; mobility and migration; language of work; income and housing. 2011 Census data topics include population and dwelling counts; age and sex; families, households and marital status; structural type of dwelling and collectives; and language. The data are collected for private dwellings occupied by usual residents. A private dwelling is a dwelling in which a person or a group of persons permanently reside. Information for the National Household Survey does not include information for collective dwellings. Collective dwellings are dwellings used for commercial, institutional or communal purposes, such as a hotel, a hospital or a work camp. **Benefits** - Useful for canada public health stakeholders, for public health specialist or specialized public and other interested parties. for health surveillance and population health research. for monitoring, planning, implementation and evaluation of health-related programs. media agencies may use the health regions data to raise awareness about health, an issue of concern to all canadians. giving the addition of longitude and latitude in some of the datasets the data can be useful to transpose the values into geographical representations. the fields descriptions along with the dataset description are useful for the user to quickly understand the data and the dataset. **License Information** The use of John Snow Labs datasets is free for personal and research purposes.
