With the president's signing into law the $787 billion economic stimulus plan earlier this week, the scramble has begun to figure out how it gets spent. A new official site, Recovery.gov, shows a ...
In computer science, a heartbeat is a periodic signal generated by hardware or software to indicate normal operation or to synchronize other parts of a computer system. [1] [2] Heartbeat mechanism is one of the common techniques in mission critical systems for providing high availability and fault tolerance of network services by detecting the network or systems failures of nodes or daemons ...
Depending on the stimulus received by the dendrites, soma may generate one or more well-separated action potentials or spike train. If the stimulus drives the membrane to a positive potential, it is an excitatory neuron; and if it drives the resting potential further in the negative direction, it is an inhibitory neuron. Figure 1.
Tempest for Eliza is a program that uses a computer monitor to send out AM radio signals, making it possible to hear computer-generated music in a radio. Video eavesdropping demo at CeBIT 2006 by a Cambridge University security researcher; eckbox – unsuccessful or abandoned attempt in spring 2004 to build an open-source Van Eck phreaking ...
