In this paper, the dynamic coupling between wind turbine rotor speed recovery (WTRSR) and inertial response of conventional virtual synchronous generator (VSG) controlled farms (WFs) is analyzed. Three distinguishing features are revealed. Firstly, characteristics VSG WFs (VSG-WFs) impaired by coupling. Secondly, when influence WTRSR dominant, VSG-WFs even worse than condition under which do no...

Wind farms (WFs) are believed to have an impact on lower boundary layer meteorology. A recent study examined satellite-measured land surface temperature data (LST) and found a local nighttime warming effect attributable to a group of four large WFs in Texas. This study furthers their work by investigating the impacts of five individual WFs in Iowa, where the land surface properties and climate ...

BACKGROUND Wolfram syndrome (WFS) is a rare, neurodegenerative disease that typically presents with childhood onset insulin dependent diabetes mellitus, followed by optic atrophy, diabetes insipidus, deafness, and neurological and psychiatric dysfunction. There is no cure for the disease, but recent advances in research have improved understanding of the disease course. Measuring disease severi...

BACKGROUND The microsporidian Enterocytozoon hepatopenaei was first described from Thailand in 2009 in farmed, indigenous giant tiger shrimp Penaeus (Penaeus) monodon. The natural reservoir for the parasite is still unknown. More recently, a microsporidian closely resembling it in morphology and tissue preference was found in Thai-farmed, exotic, whiteleg shrimp Penaeus (Litopenaeus) vannamei e...

While OGC’s WFS facilitates disseminating heterogeneous spatial data over the Web and allows feature-level geospatial information sharing and synchronization, performance issues challenge the efficient and effective utilization of WFS for disaster response. Literature shows that obtaining spatial information becomes very slow when querying WFS systems from large geospatial databases over the In...

Wave field synthesis (WFS) is a well established high-resolution spatial sound reproduction technique. Typical WFS systems aim at the reproduction in a plane using loudspeakers enclosing the plane. This constitutes a so-called 2.5-dimensional reproduction scenario. It has been shown that a spectral correction of the reproduced wave field is required in this context. For WFS this correction is k...

One of the main advantages of Wave Field Synthesis (WFS) is the existence of an extended listening area contrary to the sweet spot in stereophony. At the moment there is only little literature available on the actual localization properties of WFS at different points in the listening area. One reason is the difficulty to place different subjects reliable at different positions. This study syste...

Thirty-two Friesian calves less than one week old were purchased at a country market and fed a milk replacer at two rates, the feed being given as either one or two feeds only. Lucerne hay was available ad libitum from the start of the trial with restricted access to crushed oats after one month. The mean body weights of the once.-daily fed calves were higher than those of the twice-daily fed c...
