Coal liquefaction is a process of converting coal into liquid hydrocarbons: liquid fuels and petrochemicals. This process is often known as "coal to X" or "carbon to X", where X can be many different hydrocarbon-based products. However, the most common process chain is "coal to liquid fuels" (CTL). [1]
Business requirements in the context of software engineering or the software development life cycle, is the concept of eliciting and documenting business requirements of business users such as customers, employees, and vendors early in the development cycle of a system to guide the design of the future system.
The process-data diagram that is depicted at the right, gives an overview of all of these activities/processes and deliverables. The four gray boxes depict the four main implementation phases, which each contain several processes that are in this case all sequential.
This process is known as neurulation. [8] When the tube is closed at both ends it is filled with embryonic cerebrospinal fluid. [9] As the embryo develops, the anterior part of the neural tube expands and forms three primary brain vesicles, which become the forebrain (prosencephalon), midbrain (mesencephalon), and hindbrain (rhombencephalon).
Process decision program chart. A useful way of planning is to break down tasks into a hierarchy, using a tree diagram. The process decision program chart (PDPC) extends the tree diagram a couple of levels to identify risks and countermeasures for the bottom level tasks. Different shaped boxes are used to highlight risks and identify possible ...
In crystalline materials, Umklapp scattering (also U-process or Umklapp process) is a scattering process that results in a wave vector (usually written k) which falls outside the first Brillouin zone. If a material is periodic, it has a Brillouin zone, and any point outside the first Brillouin zone can also be expressed as a point inside the zone.
Lean Six Sigma is a process improvement approach that uses a collaborative team effort to improve performance by systematically removing operational waste [1] and reducing process variation. It combines the many tools and techniques that form the "tool box" of Lean Management and Six Sigma to increase the velocity of value creation in business ...
The agricultural cycle is the annual cycle of activities related to the growth and harvest of a crop (plant). These activities include loosening the soil, seeding, special watering, moving plants when they grow bigger, and harvesting, among others. Without these activities, a crop cannot be grown.
