The symbol used to represent pressure in equations is "p" or "P" with SI units of pascals. When describing a container of gas, the term pressure (or absolute pressure) refers to the average force the gas exerts on the surface area of the container. Within this volume, it is sometimes ...
The symbol (i) is the observations’ index. The next layer of the model consists of the coefficients’ vector ββ and the variance σ2, which are considered the priors of the model. In order to determine an idea as to the probability distribution function of each of the coefficients, ...
In a common petroleum industry operation, it is normal to see a flaring stack burning flammable gas components; the objective of this unavoidable process is to continue with the operation and maintain the safety on-field [1]. The flares usually are seen as a symbol for stable production, but...

Symbol Meaning A CAUTION notice denotes a hazard. It calls attention to an operating procedure, practice, or the like that, if not correctly performed or adhered to, could result in damage to the product or loss of important data. Do not proceed beyond a CAUTION notice until the indicated ...
The symbol \({w}_{2i}\) signifies the long-run effect in the model. The expression \({\delta }_{i}\times \left({x}_{i,t}-{x}_{i,t-1}\right)\) incorporates the lagged differences of the explanatory variable Xi,t, with the number of lagged differences determined by the ARDL...
There is growing consensus that gas-fired generators will play a crucial role during the transition to net-zero energy systems, both as an alternative to coal-fired generators and as a flexibility service provider for power systems. However, malfunctions

It is represented by the symbol H. At standard temperature and pressure, hydrogen is a colorless, odorless, nonmetallic, tasteless, highly flammable diatomic gas with the molecular formula H2. With an atomic weight of 1.00794 u, hydrogen is the lightest element. Hydrogen is the most abundant ...
The null hypothesis for this test is that there is weak cross-sectional dependence, meaning that the correlation between observations of different units at the same time is zero. Pesaran et al. (2001) derived a test statistic for both balanced and unbalanced panels. For our research, we use ...
