The Defense Advanced Research Projects Agency is an agency of the U.S. Department of Defense responsible for the development of new technologies for use by the military. DARPA has been responsible for funding the development of many technologies which have had a major effect on the world, including computer networking, as well as NLS, which was both the first hypertext system, and an important precursor to the contemporary ubiquitous graphical user interface.DARPA began as the Advanced Research Projects Agency created in 1958 by President Dwight D. Eisenhower for the purpose of forming and executing research and development projects to expand the frontiers of technology and science and able to reach far beyond immediate military requirements. The administration was responding to the Soviet launching of Sputnik 1 in 1957, and DARPA's mission was to ensure U.S. military technology be more sophisticated than that of the nation's potential enemies. From DARPA's own introduction:DARPA’s original mission, established in 1958, was to prevent technological surprise like the launch of Sputnik, which signaled that the Soviets had beaten the U.S. into space. The mission statement has evolved over time. Today, DARPA’s mission is still to prevent technological surprise to the US, but also to create technological surprise for our enemies.ARPA was renamed to "DARPA" in March 1972, then renamed "ARPA" in February 1993, and then renamed "DARPA" again in March 1996.DARPA is independent from other more conventional military research and development and reports directly to senior Department of Defense management. DARPA has around 240 personnel directly managing a $3 billion budget. These figures are "on average" since DARPA focuses on short-term projects run by small, purpose-built teams. Wikipedia.

Cognitive Radio principles were first described at a Keynote Speech by Dr. Joseph Mitola at the IEEE ICASSP Conference in Phoenix in 1999. In this talk Mitola described the principles of a Radio that could help its user to do many things. The vision includes a radio with an understanding of numerous domains ranging from the user's daily routine to an understanding of how to find and efficiently use spectrum and avoid interference. This paper will review Cognitive Radio principles explored by the commercial and defense communities, assessing progress made in the many potential dimensions of Cognitive Radio as an assistant to the radio user. We will utilize the DARPA developed Advanced Wireless Network System / Wireless Network after Next (AWNS/WNaN) radio system and network as the example of a Cognitive Radio capability that provides high levels of adaptivity to the communications radio frequency (RF) environment and the warfighter's mission. © 2013 IEEE.

Building on a long history of innovation in neural-recording interfaces, the Defense Advanced Research Projects Agency (DARPA) has launched a program to address the key challenges related to transitioning advanced neuroprosthesis technology to clinical use for amputated service members. The goal of the Reliable Neural Technology (RE-NET) Program is to develop new technology to extract information from the nervous system at a scale and rate needed to reliably control modern robotic prostheses over the lifetime of the amputee. The RE-NET program currently encompasses three separate efforts: histology for interface stability over time (HIST), reliable peripheral interfaces (RPIs), and reliable central nervous system (CNS) interfaces (RCIs). © 2012 IEEE.

Two suites of lunar impact melt samples have been measured in NASA's Reflectance Experiment Laboratory (RELAB) at Brown University. Suite 1 comprises seven Apollo 17 crystalline impact melt breccias and seven quenched glass equivalents. Suite 2 is made up of 15 additional impact melt samples (from Apollo 12, 15, 16, and 17) which exhibit a range of textures and compositions related to cooling conditions and glass abundance. A few of these samples have cooled slowly and fully crystallized, and thus have the same spectral properties as igneous rocks of similar texture and composition; they cannot be uniquely distinguished without geologic context. However, most of the impact melts and melt breccias contain either quantities of quenched glass and/or have developed microcrystalline nonequilibrium textures with well-defined, diagnostic spectral properties. The microcrystalline textures are associated with a distinctive 600-nm absorption feature, apparently due to submicroscopic ilmenite inclusions in a transparent host (typically fine-grained plagioclase). The reflectance properties of these lunar sample suites contribute to and constrain the identification and characterization of impact melts in remote sensing data. © The Meteoritical Society, 2010.

Reductionist science produces causal models of small fragments of complicated systems. Causal models of entire systems can be hard to construct because what is known of them is distributed across a vast amount of literature. The Big Mechanism program aims to have machines read the literature and assemble the causal fragments found in individual papers into huge causal models, automatically. The current domain of the program is cell signalling associated with Ras-driven cancers. © 2015 IOP Publishing Ltd. Source
