  2. Limiting factor - Wikipedia

    en.wikipedia.org/wiki/Limiting_factor

    Limiting factor. A limiting factor is a variable of a system that causes a noticeable change in output or another measure of a type of system. The limiting factor is in a pyramid shape of organisms going up from the producers to consumers and so on. A factor not limiting over a certain domain of starting conditions may yet be limiting over ...

  3. Rate-limiting step (biochemistry) - Wikipedia

    en.wikipedia.org/wiki/Rate-limiting_step...

    Rate-limiting step (biochemistry) In biochemistry, a rate-limiting step is a step that controls the rate of a series of biochemical reactions. [1][2] The statement is, however, a misunderstanding of how a sequence of enzyme catalyzed reaction steps operate. Rather than a single step controlling the rate, it has been discovered that multiple ...

  4. Diffusion-limited enzyme - Wikipedia

    en.wikipedia.org/wiki/Diffusion-limited_enzyme

    A diffusion-limited enzyme catalyses a reaction so efficiently that the rate limiting step is that of substrate diffusion into the active site, or product diffusion out. [2] This is also known as kinetic perfection or catalytic perfection. Since the rate of catalysis of such enzymes is set by the diffusion-controlled reaction, it therefore ...

  5. Rate of convergence - Wikipedia

    en.wikipedia.org/wiki/Rate_of_convergence

    Convergence rate definitions. Suppose that the sequence converges to the number . The sequence is said to converge with order to and with a rate of convergence if. for some positive constant if and if . [2][4][5] If the sequence converges but then other more technical rate definitions are called for. [6] This definition is technically called Q ...

  6. Intelligent speed assistance - Wikipedia

    en.wikipedia.org/wiki/Intelligent_speed_assistance

    ISA was born in France when Saad and Malaterre (1982) carried out their study of driver behaviour with an in-car speed limiter. Actually, they did not really test Intelligent Speed Adaptation, because the system did not automatically set the correct speed limit; instead drivers had to set the limiter themselves, and, rather like a cruise control, they could set it as they chose.

  7. Systems biology - Wikipedia

    en.wikipedia.org/wiki/Systems_biology

    Systems biology is the computational and mathematical analysis and modeling of complex biological systems. It is a biology -based interdisciplinary field of study that focuses on complex interactions within biological systems, using a holistic approach (holism instead of the more traditional reductionism) to biological research. [1 ...

  8. Primary production - Wikipedia

    en.wikipedia.org/wiki/Primary_production

    Primary production is the production of chemical energy in organic compounds by living organisms. The main source of this energy is sunlight but a minute fraction of primary production is driven by lithotrophic organisms using the chemical energy of inorganic molecules. The Calvin cycle of photosynthesis. Regardless of its source, this energy ...

  9. Setpoint (control system) - Wikipedia

    en.wikipedia.org/wiki/Setpoint_(control_system)

    In cybernetics and control theory, a setpoint (SP; [1] also set point) is the desired or target value for an essential variable, or process value (PV) of a control system, [2] which may differ from the actual measured value of the variable. Departure of such a variable from its setpoint is one basis for error-controlled regulation using ...
