    The identifications consist of up to 5 letters. The first identification letter is for the measured value, the second is a modifier, 3rd indicates passive/readout function, 4th - active/output function, and the 5th is the function modifier. This is followed by loop number, which is unique to that loop.

  3. Cost-plus pricing - Wikipedia

    en.wikipedia.org/wiki/Cost-plus_pricing

    Cost-plus pricing is a pricing strategy by which the selling price of a product is determined by adding a specific fixed percentage (a "markup") to the product's unit cost. Essentially, the markup percentage is a method of generating a particular desired rate of return. [1] [2] An alternative pricing method is value-based pricing. [3]

  4. Law of total probability - Wikipedia

    en.wikipedia.org/wiki/Law_of_total_probability

    It is known that factory X supplies 60% of the total bulbs available and Y supplies 40% of the total bulbs available. What is the chance that a purchased bulb will work for longer than 5000 hours? Applying the law of total probability, we have:

  5. Submodular set function - Wikipedia

    en.wikipedia.org/wiki/Submodular_set_function

    Recently, submodular functions have also found utility in several real world problems in machine learning and artificial intelligence, including automatic summarization, multi-document summarization, feature selection, active learning, sensor placement, image collection summarization and many other domains.

  6. Analytic function - Wikipedia

    en.wikipedia.org/wiki/Analytic_function

    Functions of each type are infinitely differentiable, but complex analytic functions exhibit properties that do not generally hold for real analytic functions. A function is analytic if and only if for every x 0 {\displaystyle x_{0}} in its domain , its Taylor series about x 0 {\displaystyle x_{0}} converges to the function in some neighborhood ...

  7. Cumulative distribution function - Wikipedia

    Cumulative distribution function for the exponential distribution Cumulative distribution function for the normal distribution. In probability theory and statistics, the cumulative distribution function (CDF) of a real-valued random variable, or just distribution function of , evaluated at , is the probability that will take a value less than or equal to .

  9. Bulk carrier - Wikipedia

    en.wikipedia.org/wiki/Bulk_carrier

    A study of mini-bulk carriers found that it takes, on average, twice as much time to unload a ship as it does to load it. [60] A mini-bulk carrier spends 55 hours at a time in port, compared to 35 hours for a lumber carrier of similar size. [60] This time in port increases to 74 hours for Handymax and 120 hours for Panamax vessels. [60]
