  2. Tilt up - Wikipedia

    en.wikipedia.org/wiki/Tilt_up

    Tilt-up construction requires significant organization and collaboration on the building site. The chronological steps that need to be taken for a tilt-up project are: site evaluation, engineering, footings and floor slabs, forming tilt-up panels, steel placement, embeds and inserts, concrete placement, panel erection and panel finishing.

  3. Lift slab construction - Wikipedia

    en.wikipedia.org/wiki/Lift_slab_construction

    Lift slab construction (also called the Youtz-Slick Method) is a method of constructing concrete buildings by casting the floor or roof slab on top of the previous slab and then raising (jacking) the slab up with hydraulic jacks. This method of construction allows for a large portion of the work to be completed at ground level, negating the ...

  4. Argon oxygen decarburization - Wikipedia

    en.wikipedia.org/wiki/Argon_oxygen_decarburization

    Prior to the decarburization step, one more step should be taken into consideration: de-siliconization, which is a very important factor for refractory lining and further refinement. The decarburization step is controlled by ratios of oxygen to argon or nitrogen to remove the carbon from the metal bath. The ratios can be done in any number of ...

  5. Tilth - Wikipedia

    en.wikipedia.org/wiki/Tilth

    Tilth is a physical condition of soil, especially in relation to its suitability for planting or growing a crop. Factors that determine tilth include the formation and stability of aggregated soil particles, moisture content, degree of aeration, soil biota, rate of water infiltration and drainage.

  6. Lift-off (microtechnology) - Wikipedia

    en.wikipedia.org/wiki/Lift-off_(microtechnology)

    The lift-off process in microstructuring technology is a method of creating structures (patterning) of a target material on the surface of a substrate (e.g. wafer) using a sacrificial material (e.g. photoresist). It is an additive technique as opposed to more traditional subtracting technique like etching.

  7. Spray forming - Wikipedia

    en.wikipedia.org/wiki/Spray_forming

    Spray forming offers certain advantages over both conventional ingot metallurgy and more specialized techniques such as powder metallurgy.Firstly, it is a flexible process and can be used to manufacture a wide range of materials, some of which are difficult to produce by other methods, e.g. Al-5wt% Li alloys or Al-SiC, Al-Al 2 O 3 metal matrix composites (MMCs).

  8. Elevated photography - Wikipedia

    en.wikipedia.org/wiki/Elevated_photography

    The remote control pan/tilt head allows the camera operator to position the camera, and frame the shot, by remotely pointing the camera up-and-down and side-to-side in order to achieve the right framing. Older remote control systems use a direct wire connection to the pan/tilt head to manually control the cameras position at the top-end.

  9. GSM Radio Frequency optimization - Wikipedia

    en.wikipedia.org/wiki/GSM_Radio_Frequency...

    GSM radio frequency optimization (GSM RF optimisation) is the optimization of GSM radio frequencies. GSM networks consist of different cells and each cell transmit signals to and receive signals from the mobile station, for proper working of base station many parameters are defined before functioning the base station such as the coverage area of a cell depends on different factors including ...
