This occurred on March 13th, 1781, when British astronomer Sir William Herschel observed the planet using a telescope of his own creation. During the 2nd century BCE, Hipparchos the Greek astronomer, mathematician and founder of trigonometry apparently recorded the planet as a star in his star catalogue (completed in 129 BCE)..

Synchronverters have gained interest due to their capability of emulating synchronous machines (SMs), offering self synchronization to the grid. Despite the simplicity of the control structure, the adoption of an LCL filter makes the overall model complex again, posing questions regarding the tuning of the synchronverter and its robustness. The multi inputs multi outputs (MIMO) formulation of the problem requires multivariable analysis.

This study investigates the effect of water pressure on hydrocarbon generation and source rock maturation at high maturities for a perhydrous Tertiary Arctic coal, Svalbard. Using a 25 ml Hastalloy vessel, the coal was pyrolysed under low water pressure (230 “300 bar) and high water pressure (500, 700 and 900 bar) conditions between 380 C and 420 C for 24 h. At 380 C and 420 C, gas yields were not affected by pressure up to 700 bar, but were reduced slightly at 900 bar.

Here at the Seismo Lab, it our responsibility to verify that all of the info we putting out about earthquakes the locations and magnitudes, for example are correct. We responsible for getting info about the origin out within two minutes of the shaking, so we have fully automated systems that send updates to the National Earthquake Information Center right away. All of that happens without anyone touching anything, before we can even get to our desks.
