The base of a tunnel on which the road or railway may be laid and used when construction is through unstable ground. It may be flat or form a continuous curve with the tunnel arch. invert (in'‑vert) The floor or bottom of the internal cross section of a closed conduit, such as an aqueduct, tunnel, or drain - The term originally referred to the inverted arch used to form the bottom of a masonry‑lined sewer or tunnel (Jackson, 1997) Wilson, W.E., Moore, J.E., (2003) Glossary of Hydrology, Berlin: Springer
The lowest point of the internal cross section of a channel or sewer Inverted Syphon A portion of pipe or conduit in which the sewage flows under pressure, due to the sewer dropping below the hydraulic gradient and then rising again
If you invert something, you change it to its opposite. They may be hoping to invert the presumption that a defendant is innocent until proved guilty. a telling illustration of inverted moral values. to put something in the opposite position to the one it was in before, especially by turning it upside down (=the bottom is on the top and the top is on the bottom) (invertere, from vertere )
To move the root note of a chord up or down an octave, resulting in a change in pitch
a method of the MeasurementModel is the opposite of predict() Consider the A Matrix formalism: D = AS Invert is the operation which, when applied to D, yields an estimate of S: (ATA)-1ATD = S
To turn over; to put upside down; to upset; to place in a contrary order or direction; to reverse; as, to invert a cup, the order of words, rules of justice, etc
The structure constructed in a drift to provide the floor of that drift In an emplacement drift, ballast in the invert would serve as a barrier to migration of radionuclides that escaped from breached waste packages
turn upside down -- " the reciprocal looks as if the fraction has been inverted " (156)
To view the image inverted or upside down (i e reversing the direction of the Vertical (Y) coordinate)
The lowest portion of the internal cross section of a pipe or fitting BACK TO PAGE
To change the position of; - - said of tones which form a chord, or parts which compose harmony
Water enters the storm drain at this elevation Water doesn't flow up hill so this is important Example: manhole inlet, for stormwater, manhole inlet for wastewater
The term generally used to describe any error where one portion of the design is inverted in relation to the other portion(s) An overprint applied upside down is also an invert
An equal mixture of glucose and fructose formed by the enzymatic hydrolysis of sucrose; it is found in honey and some fruits, and also produced industrially
(Mühendislik) In civil engineering, the invert level is the base interior level of a pipe, trench or tunnel; it can be considered the "floor" level. Conversely, the crown level is the highest interior level, and can be considered the "roof" level
A mixture of equal parts of glucose and fructose resulting from the hydrolysis of sucrose. It is found naturally in fruits and honey and produced artificially for use in the food industry
A relatively new type of coaster where the trains hang below the track On an inverted the cars are rigifly attached and do not swing out, however, loops can be accomplished with this design
A coaster that rides below the track rather than on the track The cars on this type of coaster are rigidly connected to their wheel assembly Compare with Suspended
A device that changes direct current (DC) into alternating current (AC) Direct current is created by photovoltaic modules or batteries and converted to AC through the use of an inverter
A device which changes direct current (DC) into alternating current (AC) Direct current is created by photovoltaic modules or batteries and converted to AC through the use of an inverter
an electrical device which is designed to convert direct current into alternating current This was originally done with rotating machines which produced true sine wave ac output More recently this conversion has been performed more economically and efficiently using solid state electronics However, except for the most expensive models, these devices usually do not produce perfect sine wave output This sometimes can result in electromagnetic interference with other sensitive electronic devices
An electronic device that converts low voltage DC to high voltage AC power In solar-electric systems, an inverter may take the 12, 24, or 48 volts DC and convert it to 115 or 230 volts AC, conventional household power
A power converter; as commonly used to derive line-power backup from batteries Inverters chop a battery's DC output voltage into time varying segments to produce an AC power signal
