From theCambridge English Corpus The gradient in muscle tension created along the intestine (increased in jejunum and decreased in ileum) may promotepropulsionof worms in the lumen. From theCambridge English Corpus Propulsionobtains the dimensions it requires from hull, determines the ver tical center of gravity for stability, and provides total thrust to resistance. From theCambridge English Corpus This hopper included a translational offset mass in order to cause the tipping action that helped in forwardpropulsion. From theCambridge English Corpus This is a useful generalized account, serving as an introduction to the short discussion of hypersonicpropulsionthat is given later. From theCambridge English Corpus Also, carangiformpropulsionis more convenient for engineering realization. From theCambridge English Corpus Calculated efficiencies are found to be insufficient forpropulsionapplications that require short periods of acceleration but ion-beam propulsion shows some potential for prolonged flights. From theCambridge English Corpus Here, the selective pressures for efficient maintenance of high-speedpropulsionappear to be responsible for the convergent evolution of caudal fins of high aspect ratio. From theCambridge English Corpus It also includes fault-tolerant control of a chemical process, and of a shippropulsionsystem, and of a steam generator. From theCambridge English Corpus They are of interest because they may represent the first economically viable application of laser ablationpropulsion. From theCambridge English Corpus Here, we do not want the extraction short hairs = ciliapropulsion. From theCambridge English Corpus Advancements in computer and control technologies have, in this case, enabledpropulsionby delicately controlling elastic fins on the fish. From theCambridge English Corpus This subject has been carefully and continuously studied ever since jetpropulsionbecame technologically feasible. From theCambridge English Corpus Such a control strategy allows us to influence forwardpropulsionto assure constant gait velocity. From theCambridge English Corpus In addition, it provides a method of generating plasma magnetospheres for laboratory simulation of astrophysical studies and spacepropulsion.
