Pourbaix diagram of iron. [1] The Y axis corresponds to voltage potential. In electrochemistry, and more generally in solution chemistry, a Pourbaix diagram, also known as a potential/pH diagram, E H –pH diagram or a pE/pH diagram, is a plot of possible thermodynamically stable phases (i.e., at chemical equilibrium) of an aqueous electrochemical system.
In telecommunications, the free-space path loss (FSPL) (also known as free-space loss, FSL) is the attenuation of radio energy between the feedpoints of two antennas that results from the combination of the receiving antenna's capture area plus the obstacle-free, line-of-sight (LoS) path through free space (usually air).

The Global Offset Table is represented as the .got and .got.plt sections in an ELF file [5] which are loaded into the program's memory at startup. [5] [6] The operating system's dynamic linker updates the global offset table relocations (symbol to absolute memory addresses) at program startup or as symbols are accessed. [7]
Example Bjerrum plot: Change in carbonate system of seawater from ocean acidification.. A Bjerrum plot (named after Niels Bjerrum), sometimes also known as a Sillén diagram (after Lars Gunnar Sillén), or a Hägg diagram (after Gunnar Hägg) [1] is a graph of the concentrations of the different species of a polyprotic acid in a solution, as a function of pH, [2] when the solution is at ...
The Apache Trafodion project provides a SQL query engine with ODBC and JDBC drivers and distributed ACID transaction protection across multiple statements, tables and rows that use HBase as a storage engine. HBase is now serving several data-driven websites [3] but Facebook's Messaging Platform migrated from HBase to MyRocks in 2018.
Flux limiters are used in high resolution schemes – numerical schemes used to solve problems in science and engineering, particularly fluid dynamics, described by partial differential equations (PDEs).
Changing the pH modifies the apparent flatband potential by 570 mV corresponding to a 59 mV displacement per unit of pH. From the slope the donor density N D = 1.1 x 10 21 cm −3 is determined. Then the same sample is measured after nanostructured TiO 2 is deposited on top of FTO. The observed change of slope is due to the decrease of the ...
HSQLDB (Hyper SQL Database) is a relational database management system written in Java. It has a JDBC driver and supports a large subset of SQL-92, SQL:2008, SQL:2011, and SQL:2016 standards. [2] It offers a fast, [3] small (around 1300 kilobytes in version 2.2) database engine which offers both in-memory and disk-based tables. Both embedded ...
