  2. Engineering statistics - Wikipedia

    en.wikipedia.org/wiki/Engineering_statistics

    Engineering statistics involves data concerning manufacturing processes such as: component dimensions, tolerances, type of material, and fabrication process control. There are many methods used in engineering analysis and they are often displayed as histograms to give a visual of the data as opposed to being just numerical.

    The summary statistics is particularly useful and popular when used to evaluate models where the dependent variable is binary, taking on values {0,1}. Example [ edit ]

  4. Systems Engineering Body of Knowledge - Wikipedia

    en.wikipedia.org/wiki/Systems_Engineering_Body...

    The Systems Engineering Body of Knowledge (SEBoK), formally known as Guide to the Systems Engineering Body of Knowledge, is a wiki-based collection of key knowledge sources and references for systems engineering. [1] The SEBoK is a curated wiki meaning that the content is managed by an editorial board, and updated on a regular basis.

  5. Computer-aided engineering - Wikipedia

    On the software side, they are constantly looking to develop more powerful solvers, to better utilize computer resources, and to include engineering knowledge in pre and post-processing. On the process side, they try to achieve a better alignment between 3D CAE, 1D system simulation, and physical testing.

  6. Pre- and post-test probability - Wikipedia

    en.wikipedia.org/wiki/Pre-_and_post-test_probability

    Pre-test state (and thus the pre-test probability) does not have to be same as in reference group: By relative risk: Quotient of risk among exposed and risk among unexposed: Pre-test probability multiplied by the relative risk: Low, unless subsequent relative risks are derived from same multivariate regression analysis: Relatively intuitive to use

  7. Piping and instrumentation diagram - Wikipedia

    en.wikipedia.org/wiki/Piping_and_instrumentation...

    P&IDs are originally drawn up at the design stage from a combination of process flow sheet data, the mechanical process equipment design, and the instrumentation engineering design. During the design stage, the diagram also provides the basis for the development of system control schemes, allowing for further safety and operational ...

    The Caterpillar 797 is a series of off-highway, ultra class, two-axle, mechanical powertrain haul trucks developed and manufactured in the United States by Caterpillar Inc. specifically for high-production mining and heavy construction applications worldwide. [1]

  9. Solar tracker - Wikipedia

    en.wikipedia.org/wiki/Solar_tracker

    The effective collection area of a flat-panel solar collector varies with the cosine of the misalignment of the panel with the Sun.. Sunlight has two components: the "direct beam" that carries about 90% of the solar energy [6] [7] and the "diffuse sunlight" that carries the remainder – the diffuse portion is the blue sky on a clear day, and is a larger proportion of the total on cloudy days.
