The basis for STEP was the Product Data Exchange Specification (PDES), which was initiated during the mid-1980's and was submitted to ISO in 1988. [ 4 ] [ 5 ] The Product Data Exchange Specification (PDES) was a data definition effort intended to improve interoperability between manufacturing companies, and thereby improve productivity.
A pulse detonation engine (PDE) is a type of propulsion system that uses detonation waves to combust the fuel and oxidizer mixture. [1][2] The engine is pulsed because the mixture must be renewed in the combustion chamber between each detonation wave and the next. Theoretically, a PDE can operate from subsonic up to a hypersonic flight speed of ...
Manufacturing Execution Systems, known as MES are software programs created to oversee and enhance production operations. They play a role, in boosting efficiency resolving production line issues swiftly and ensuring transparency by collecting and analyzing real time data. MES systems effectively manage production resources like materials ...
t. e. In mathematics, a partial differential equation (PDE) is an equation which computes a function between various partial derivatives of a multivariable function. The function is often thought of as an "unknown" to be solved for, similar to how x is thought of as an unknown number to be solved for in an algebraic equation like x2 − 3x + 2 = 0.
Laboratory information management system. Lab orders in the LIMS module of the GNU Health project. A laboratory information management system (LIMS), sometimes referred to as a laboratory information system (LIS) or laboratory management system (LMS), is a software -based solution with features that support a modern laboratory 's operations.
A recipe in semiconductor manufacturing is a list of conditions under which a wafer will be processed by a particular machine in a processing step during manufacturing. [157] Process variability is a challenge in semiconductor processing, in which wafers are not processed evenly or the quality or effectiveness of processes carried out on a ...
A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations. Another commonly used term for a PFD is ...
In 2018, the Allam-Fetvedt Cycle and supporting technologies were validated, [17] allowing OEMs to certify components for use with future production plants. On November 15, 2021, at approximately 7:40 pm EST the test facility successfully synchronized to the ERCOT grid [ 18 ] proving that the Allam Fetvedt Cycle was capable of generating power ...
