Value engineering can lead to the substitution of lower-cost materials, as with the exterior cladding that accelerated the Grenfell Tower fire in London. [1] [2]Value engineering (VE) is a systematic analysis of the functions of various components and materials to lower the cost of goods, products and services with a tolerable loss of performance or functionality.
In physics, chemistry, and other related fields like biology, a phase transition (or phase change) is the physical process of transition between one state of a medium and another. Commonly the term is used to refer to changes among the basic states of matter : solid , liquid , and gas , and in rare cases, plasma .
The dielectric may begin to leak current at higher temperature, or may lose adhesion when expanding at a different rate from the phase-change material. Phase-change memory is susceptible to a fundamental tradeoff of unintended vs. intended phase-change. This stems primarily from the fact that phase-change is a thermally driven process rather ...

The Miles Value Foundation was established in 1977 "to promote and fund the development of educational programs, new applications, and [to establish] a research library for the study of the Value Methodology". [3]
In physics, the phase problem is the problem of loss of information concerning the phase that can occur when making a physical measurement. The name comes from the field of X-ray crystallography , where the phase problem has to be solved for the determination of a structure from diffraction data. [ 1 ]
The discontinuity in , and other properties, e.g. internal energy, , and entropy,, of the substance, is called a first order phase transition. [12] [13] In order to specify the unique experimentally observed pressure, (), at which it occurs another thermodynamic condition is required, for from Fig.1 it could clearly occur for any pressure in the range .
The standard was developed over a five-year period based on the initial work published in "Ethical IT innovation: A value-based system design approach" in 2015. [2] Similar to value sensitive design , the standard's intent is to provide a framework for the consideration of human values and ethical concerns. [ 3 ]
