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 three diagrams are constructed from the P–alpha diagram by using appropriate coordinate transformations. Not a thermodynamic diagram in a strict sense, since it does not display the energy–area equivalence, is the Stüve diagram; But due to its simpler construction it is preferred in education.

The trireme derives its name from its three rows of oars, manned with one man per oar. The early trireme was a development of the penteconter, an ancient warship with a single row of 25 oars on each side (i.e., a single-banked boat), and of the bireme (Ancient Greek: διήρης, diērēs), a warship with two banks of oars, of Phoenician ...
For diagrams that do not possess grid lines, the easiest way to determine the values is to determine the shortest (i.e. perpendicular) distances from the point of interest to each of the three sides. By Viviani's theorem , the distances (or the ratios of the distances to the triangle height ) give the value of each component.
It combines continuous parameters such as dimension and size of the primitive shapes, and discrete parameters such as the Boolean operators used to build the final CSG tree. Deductive methods solve this problem by building a set of half-spaces that describe the interior of the geometry. These half-spaces are used to describe primitives that can ...
John Francis Coates, OBE (30 March 1922 – 10 July 2010) was a British naval architect best known for his work on the study of construction of the Ancient Greek trireme.His research led to the construction of the first working replica of triremes, the fastest and most devastating warship of Classical Mediterranean empires, and gave a greater understanding of how they were built and used.
