  2. Cost breakdown analysis - Wikipedia

    en.wikipedia.org/wiki/Cost_breakdown_analysis

    The cost breakdown analysis is even more effective when repeated constantly, so that changes in the respective shares in total costs of the various cost drivers can be tracked down. Over a five-year period, the share of expenses for tires might have risen from 5% to 8%, accompanied by a decrease of expenses for personnel from 35% to 32%, which ...

  4. Oxy-fuel welding and cutting - Wikipedia

    en.wikipedia.org/wiki/Oxy-fuel_welding_and_cutting

    Operating cost for a gasoline torch is typically 75-90% less than using propane or Acetylene. The gasoline can be fed either from a pressurized tank (whose pressure can be hand-pumped or fed from a gas cylinder) or a non-pressurized tank, with the fuel being drawn into the torch by a venturi action created by the pressurized oxygen flow.

    Layers of protection analysis (LOPA) is a technique for evaluating the hazards, risks and layers of protection associated with a system, such as a chemical process plant. In terms of complexity and rigour LOPA lies between qualitative techniques such as hazard and operability studies (HAZOP) and quantitative techniques such as fault trees and ...

    A high temperature phase which is done before layer transfer followed by a layer transfer using ion-cut, also known as layer transfer, which has been used to produce Silicon on Insulator (SOI) wafers for the past two decades. Multiple thin (10s–100s nanometer scale) layers of virtually defect-free Silicon can be created by utilizing low ...

  9. Third-generation photovoltaic cell - Wikipedia

    en.wikipedia.org/wiki/Third-generation...

    For a two layer cell, one layer should be tuned to 1.64 eV and the other at 0.94 eV, with a theoretical performance of 44%. A three-layer cell should be tuned to 1.83, 1.16 and 0.71 eV, with an efficiency of 48%. A theoretical "infinity-layer" cell would have a theoretical efficiency of 68.2% for diffuse light. [11]
