通信系统浪涌保护器的性能试验及评价分析

浪涌保护器（SPD）的作用是把窜入电力线、信号传输线的瞬时过电压限制在设备或系统所能承受的电压范围内,或将强大的雷电流泄流入地,使被保护的设备或系统不受冲击而导致损坏.对于通信系统来说,其过电压保护与电气设备相比,有不同的技术要求.依据GB/T 18802.22-2008电信和信号网络的电涌保护器选择和使用导则,对通信系统所用电涌保护器进行了试验,并结合样品测试分析结果,在对照国标要求进行解读的基础上,提出对信号SPD的性能评价及建议.

Broadband and digital ‘content’ in the EU-25: Recent trends and challenges

This paper focuses on recent trends and issues in the EU-25 countries related to one key broadband application area: digital media ‘content’ applications. It draws upon recently completed research addressing current and future uses and applications of broadband in the EU-25 area.

The paper presents key findings from the BEACON project concerning the broadband content trends and issues in the EU-25 countries. First, the paper briefly considers recent literature on broadband and digital media innovations as well as the policy context in Europe, which has an important influence on framing supports for innovation in content and digital media. Next, it addresses a number of key issues that impact upon the creation of content services. These include the high cost of content production and the difficulty of forming attractive business cases given the uncertainties related to user demand, and the IPR and copyright regimes. It will also consider users’ patterns of engagement with broadband content and emerging user applications. Next, the paper discusses whether broadband is reaching a ‘tipping point’, whereby broadband access is becoming the norm and in the next five years we will see the emergence of innovative, dynamic content services. The paper considers whether recent moves by three sets of significant actors (media corporations, the advertising sector, and EC regulators) could be early signs of a tipping point in favour of the creation of and more focused support for broadband content services.

On the Universal Computing Power of Amorphous Computing Systems

Amorphous computing differs from the classical ideas about computations almost in every aspect. The architecture of amorphous computers is random, since they consist of a plethora of identical computational units spread randomly over a given area. Within a limited radius the units can communicate wirelessly with their neighbors via a single-channel radio. We consider a model whose assumptions on the underlying computing and communication abilities are among the weakest possible: all computational units are finite state probabilistic automata working asynchronously, there is no broadcasting collision detection mechanism and no network addresses. We show that under reasonable probabilistic assumptions such amorphous computing systems can possess universal computing power with a high probability. The underlying theory makes use of properties of random graphs and that of probabilistic analysis of algorithms. To the best of our knowledge this is the first result showing the universality of such computing systems. This research was carried out within the institutional research plan AV0Z10300504 and partially supported by the GA ČR grant No. 1ET100300517 and GD201/05/H014. A preliminary, shorter version of this paper has been presented at the Third Conference on Computability in Europe, CiE 2007, Siena, Italy, June 2007 and published in the proceedings from this conference.
