Aquaculture or farming in water is the aquatic equivalent of agriculture or farming on land. Defined broadly, agriculture includes farming both animals (animal husbandry) and plants (agronomy, horticulture and forestry in part). Similarly, aquaculture covers the farming of both animals (including crustaceans, finfish and molluscs) and plants (including seaweeds and freshwater macrophytes).
FSRU (Floating Storage Regasification Unit) is special floating vessel that stores gas and regasifies the LNG tanker. Studies on FSRU have been developed by many engineering and oil & gas company and some of them have been approved by ABS (American Bureau Standard). Currently several FSRU is under construction and will be operating in the near time. FSRU incorporate many of the same safety features as an LNG carrier and each of the technologies and components involved are tried, tested, and reliable.
The parameter VSWR is a measure that numerically describes how well the antenna is impedance matched to the radio or transmission line it is connected to. VSWR stands for Voltage Standing Wave Ratio, and is also referred to as Standing Wave Ratio (SWR). VSWR is a function of the reflection coefficient, which describes the power reflected from the antenna. If the reflection coefficient is given by , then the VSWR is defined by the following formula:
