基于机智云平台的滚动轴承在线监测系统

设计了一种基于云平台的滚动轴承在线监测系统,信号采集模块将振动传感器输出的振动信号进行变换,再通过有源滤波模块处理后交给控制器,控制器内部进行A/D采样,随后处理器对A/D采样后的信号进行参数的运算,最后将参数通过云平台传输协议模块,在利用WiFi转发给远程机智云平台服务器.该系统为滚动轴承的监测提供了一个平台,在这个平台上工程人员可以通过远程的云服务器和APP终端对滚动轴承的状态进行了解,很大程度上减少了工程人员的工作量,提高了对滚动轴承监测的效率.

The supremacy of online white supremacists – an analysis of online discussions by white supremacists

A content analysis was conducted on five different white supremacist online forums to observe the discourse and types of activities occurring within. In addition, web link analysis was conducted on the forums to identify the presence of external links being posted and discussed by members. We found that members used the forums primarily for information provision, recruitment and networking. Based on these results, we discuss the implications that online hate speech have within offline settings, and the affects these activities have on Canadian citizens in light of the recent repeal of section 13 of the Canadian Human Rights Act (1985), the primary tool in Canada with which to deal with hate speech and other activities observed. The insights extracted from this research have provided novel insight into the sentiments and activities of the white supremacist movement online, a relatively unexplored venue of hate speech and propaganda online.     

How to maneuver in the world of negative online reviews,the important ethical considerations for attorneys,and changes needed to protect the legal profession

The advent of the Internet and social media has revolutionized the way society communicates, the speed in which news is disseminated, and the approach that people take in their daily decision-making. Online reviews are now common place on nearly every consumer-related website. Consequently, attorneys are also being publicly scrutinized by their clients on a range of topics from price, competence, satisfaction, personality, communication, and effectiveness. On one side of the coin, this new phenomenon can be very rewarding since attorneys were previously limited to receiving a small number of referrals from the word-of-mouth promotion before the creation of online reviews. However, the exact opposite is true. Negative online reviews, whether accurate or not, may deter potential clients from even giving the attorney a second thought. As a result, a firm's business can feel the immediate impact of negative reviews. Attorneys, who legitimately need and want to protect their business and reputation, cannot speak freely online to defend their honor. Rather, an attorney must be mindful of not disclosing confidential client information or crossing other ethical lines that may then expose the attorney to potential discipline. There are several interests that must be considered such as allowing attorneys to exercise their First Amendment right to free speech, respect and adherence to the ethical rules of non-disclosure of confidential information, allowing attorneys to preserve their reputation, and protecting an attorney's marketability and means of generating income. This article explores the trend in offering reviews online in a variety of industries, including legal services, the statistical findings regarding the prevalence of this information and consumers' reliance on the information while making a purchasing decision. This article also considers the positive and negative implications of the reviews being so widely spread, while highlighting unique considerations as it relates to the practice of law and factors that may greatly skew a reviewer and reader's perceptions. Next, this article outlines the ethical considerations of attorneys if they want to respond to negative online feedback, such as disclosure of confidential information. Then, this article analyzes the American Bar Association (ABA) and several US states' ethics opinions for guidance for attorneys who wish to respond negative reviews. Finally, this article details the author's recommendations for attorneys, the ABA, and the US states and propose the areas where additional ethics opinions, rules and guidelines should be focused to establish a proper balance between the valuable insights discovered from a client's review and attorneys' legitimate interests in protecting their reputation and livelihood from inaccurate, malicious, or erroneous postings.

The Battle Over E-commerce Sales Taxes Heats Up

The inability of states to collect sales taxes from online vendors is a salient issue during the current economic decline. Further, brick and mortar retailers, who must charge customers sales tax, have pushed for legislation requiring online vendors to also do so. States have enacted legislation requiring online vendors, such as Amazon.com LLC, to collect and pay these taxes. In this article the authors describe the issue and make recommendations for resolution.

The (Uncertain) Future of Libraries in a Google World

Abstract

Libraries are in competition with other entities that provide information access to students, scholars and the general public. This constitutes a radical change in the information environment. The library profession's failure to take seriously the change that has taken place in the information environment, and to respond with fundamental changes of its own, may well spell disaster for the library as we know it.
