The biggest problem with sanitary technology in high-rise buildings is the design of foul water stacks in which high negative pressure and overpressure values must not occur.When pressure exceeds maximum values, water from the trap is ejected, sucked out, or left bubbling hair care travel in the trap.Measurements by other researchers have shown tha
This paper analyzes the low-frequency stability challenges that exist in a complex DC microgrid (MG) system.The converters that belong to a DC MG are categorized into different groups based on their control approach.The small-signal model of the DC MG is presented, and the conditions for system stability are derived.In some DC MG applications, ther
This study examined three-dimensional, volumetric mean velocity fields and corresponding performance measurements for an isolated vertical-axis wind turbine (VAWT) and for co- and counter-rotating pairs of VAWTs with varying incident wind direction and turbine spacings.The purpose was to identify turbine configurations and flow mechanisms Smoothie
Pressure, water vapor pressure, temperature, and weighted mean temperature (Tm) are tropospheric parameters that play an important role in high-precision global navigation satellite system navigation (GNSS).As accurate tropospheric parameters are obligatory in GNSS navigation and GNSS water vapor detection, high-precision modeling of tropospheric p
