Self-Protecting Digital Content
{{Refimprove, date=March 2008 Self Protecting Digital Content (SPDC), is a copy protection ( digital rights management) architecture which allows restriction of access to, and copying of, the next generation of optical discs and streaming/downloadable content. Overview Designed by Cryptography Research, Inc. of San Francisco, SPDC executes code from the encrypted content on the DVD player, enabling the content providers to change DRM systems in case an existing system is compromised. It adds functionality to make the system "dynamic", as opposed to "static" systems in which the system and keys for encryption and decryption do not change, thus enabling one compromised key to decode all content released using that encryption system. "Dynamic" systems attempt to make future content released immune to existing methods of circumvention. Playback method If a method of playback used in previously released content is revealed to have a weakness, either by review or because it has a ...

Shell Petroleum Development Company
Shell Nigeria is the common name for Shell plc's Nigerian operations carried out through four subsidiaries—primarily Shell Petroleum Development Company of Nigeria Limited (SPDC). Royal Dutch Shell's joint ventures account for more than 21% of Nigeria's total petroleum production ( (bpd) in 2009). The company has been controversial in communities in the Niger Delta, who point to its poor environmental record and that most of the economic benefit from oil exploitation has not benefited local communities. In particular, when, in 1993 the Movement for the Survival of the Ogoni People (MOSOP) organized large protests against Shell and the government, it led to repression of the local community. The company has been responsible for some significant oil spills in the Niger delta, and both Nigerian and European courts have held them liable for environmental destruction. One of the most significant cases was at one of Shell's oil extraction facilities located in the Ejama-Ebubu commun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
State Peace And Development Council
The State Peace and Development Council ( my, နိုင်ငံတော် အေးချမ်းသာယာရေး နှင့် ဖွံ့ဖြိုးရေး ကောင်စီ ; abbreviated SPDC or , ) was the official name of the military government of Burma (Myanmar) which, in 1997, succeeded the State Law and Order Restoration Council ( my, နိုင်ငံတော်ငြိမ်ဝပ်ပိပြားမှုတည်ဆောက်ရေးအဖွဲ့ that seized power under the rule of Saw Maung in 1988. On 30 March 2011, Senior General and Council Chairman Than Shwe signed a decree that officially dissolved the council. From 1988 to 1997, the junta was known as the State Law and Order Restoration Council ( my, နိုင်ငံတော် ငြိမ်ဝပ်ပိပြားမှု တည်ဆောက်ရေးအဖွဲ့, links=no; abbreviated SLORC or ), which had succeeded the Pyithu Hluttaw as a leg ...

Spontaneous Parametric Down-conversion
Spontaneous parametric down-conversion (also known as SPDC, parametric fluorescence or parametric scattering) is a nonlinear instant optical process that converts one photon of higher energy (namely, a pump photon), into a pair of photons (namely, a signal photon, and an idler photon) of lower energy, in accordance with the law of conservation of energy and law of conservation of momentum. It is an important process in quantum optics, for the generation of entangled photon pairs, and of single photons. Basic process A nonlinear crystal is used to produce pairs of photons from a photon beam. In accordance with the law of conservation of energy and law of conservation of momentum, the pairs have combined energies and momenta equal to the energy and momentum of the original photon. Because the index of refraction changes with frequency (dispersion), only certain triplets of frequencies will be phase-matched so that simultaneous energy and momentum conservation can be achieved.

Social Policy And Development Centre
Based in Karachi, Pakistan, the Social Policy and Development Centre (SPDC) is considered one of the pre-eminent economic policy research institutions in Pakistan and its services are much in demand by the government, civil society, academia, students and donors. Established in April 1995, its research is aimed at raising the comprehension and awareness of the issues and problems of social development and influencing government policies. The Institution's research areas include monetary policy, fiscal policy, poverty, inequality, education, governance, gender, international trade and pro-poor macroeconomic policy. Major activities of SPDC include research and policy analysis, social sector The voluntary sector, independent sector, or civic sector is the realm of social activity undertaken by organizations that are Non-governmental organization, non-governmental nonprofit organizations. This sector is also called the third sector, co ... database support, institutional analysis and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steorn
Steorn Ltd () was a small, private technology development company based in Dublin, Ireland. In August 2006, it announced that it had developed a technology to provide "free, clean, and constant energy" via an apparent perpetual motion machine, something which is contrary to the law of conservation of energy, a fundamental principle of physics. Steorn challenged the scientific community to investigate their claim and, in December 2006, said that it had chosen a jury of scientists to do so. In June 2009 the jury gave its unanimous verdict that Steorn had not demonstrated the production of energy. Steorn gave two public demonstrations of their technology. In the first demonstration, in July 2007 at the Kinetica Museum in London, the device failed to work. The second demonstration, which ran from December 2009 to February 2010 at the Waterways Visitor Centre in Dublin, involved a motor powered by a battery and provided no independent evidence that excess energy was being generated. ...
