  2. Static timing analysis - Wikipedia

    en.wikipedia.org/wiki/Static_timing_analysis

    The arrival time of a signal is the time elapsed for a signal to arrive at a certain point. The reference, or time 0.0, is often taken as the arrival time of a clock signal. To calculate the arrival time, delay calculation of all the components in the path will be required. Arrival times, and indeed almost all times in timing analysis, are ...

  3. Statistical static timing analysis - Wikipedia

    en.wikipedia.org/wiki/Statistical_static_timing...

    Statistical static timing analysis. Conventional static timing analysis (STA) has been a stock analysis algorithm for the design of digital circuits for a long time. However the increased variation in semiconductor devices and interconnect has introduced a number of issues that cannot be handled by traditional (deterministic) STA.

  4. State observer - Wikipedia

    en.wikipedia.org/wiki/State_observer

    In control theory, a state observer or state estimator is a system that provides an estimate of the internal state of a given real system, from measurements of the input and output of the real system. It is typically computer-implemented, and provides the basis of many practical applications. Knowing the system state is necessary to solve many ...

  6. Single-stage-to-orbit - Wikipedia

    en.wikipedia.org/wiki/Single-stage-to-orbit

    The VentureStar was a proposed SSTO spaceplane. A single-stage-to-orbit ( SSTO) vehicle reaches orbit from the surface of a body using only propellants and fluids and without expending tanks, engines, or other major hardware. The term usually, but not exclusively, refers to reusable vehicles. [1] To date, no Earth-launched SSTO launch vehicles ...

    The area of Alaska is 18% of the area of the United States and equivalent to 21% of the area of the contiguous United States. The second largest state, Texas, has only 40% of the total area of the largest state, Alaska. Rhode Island is the smallest state by total area and land area. San Bernardino County is the largest county in the contiguous ...

  8. State space (computer science) - Wikipedia

    en.wikipedia.org/wiki/State_space_(computer_science)

    Definition. State spaces are useful in computer science as a simple model of machines. Formally, a state space can be defined as a tuple [ N , A , S , G] where: N is a set of states. A is a set of arcs connecting the states. S is a nonempty subset of N that contains start states. G is a nonempty subset of N that contains the goal states.

    en.wikipedia.org/wiki/Daylight_saving_time_in...

    The Uniform Time Act of 1966 established the system of uniform daylight saving time throughout the US. [1] In the U.S., daylight saving time starts on the second Sunday in March and ends on the first Sunday in November, with the time changes taking place at 2:00 a.m. local time. With a mnemonic word play referring to seasons, clocks "spring ...
