One of the more unusual revelations of the Snowden leaks was the discovery that UK and US security services had also targeted popular online gaming platforms for surveillance activity. While the British press had a field day coming up with creative headlines about “undercover Orcs”, public reaction was muted. Anger about “wasting taxpayer’s money” more than privacy concerns dominated the debate. But can we really dismiss surveillance of gaming as “not quite serious”? Using insights from psychology, anthropology and cultural studies, we argue that on the contrary, surveillance of people at play can be seen as a paradigmatic illustration of the dangers of the surveillance society, and give us insights in the values privacy law ought to protect. 相似文献

For synchronization of high-precision stage systems, in particular the synchronization between a wafer and a reticle stage system of a wafer scanner, a master–slave controller design is presented. The design consists of a synchronization controller based on FIR filters and a data-driven self-tuning approach is used to find the coefficients of these filters. In the context of Lur'e systems, i.e. the reticle stage slave system has a variable gain controller with saturation nonlinearity, a part of the gradients needed for self-tuning is obtained from reconstruction using closed-loop nonlinear models. The remaining part is given by sampled data obtained primarily from time-series measurements. Performance with the synchronization controller is shown to be bounded by a waterbed effect: low-frequency suppression comes at the price of high-frequency amplification. For the considered Lur'e stage systems the ability of the self-tuning to induce improved tracking is discussed in view of this waterbed effect for either simulation results or experimental results. 相似文献

After the initial hype, WAP, the wireless application protocol, aka the Wireless Internet, has disappointed many users. In the US, the wireless powers-that-be continue to look for wireless data service offerings to compete with voice as a revenue generator. Wireless messaging services have yet to take hold in the US, despite their success in Japan and Europe; the author gives some reasons why 相似文献

“那一月我摇动所有的经筒,不为超度,只为触摸你的指尖; 那一年磕长头在山路,不为觐见,只为贴着你的温暖; 那一世转山,不为修来世,只为途中与你相见。” 写下这首深情诗篇的,是西藏历史上的诗 相似文献
