The equation of continuity is used to estimate profiles of vertical velocity between 25 and 120 m from moored current measurements in arrays nested within the triangle with vertices located at 1ø30'S, 140øW and along the equator at 140 ø and 110øW during December 1983 through March 1984 and May-September 1984. All directions of the 4to 5-month mean values were upward. The ensemble averaged mean...

This paper demonstrates a method for using an autonomous underwater vehicle to measure the velocity of a deep-sea hydrothermal plume. Based on a system identification experiment conducted in the actual operating environment, we extracted a dynamic model of the vehicle's vertical response, then used that model to infer the vertical water velocity of rising plumes in the main observation area. Th...

We consider the effect of vertical outflows on the mean-field dynamo in a thin disk. These outflows could be due to winds or magnetic buoyancy. We analyse both two-dimensional finite-difference numerical solutions of the axisymmetric dynamo equations and a free-decay mode expansion using the thin-disk approximation. Contrary to expectations, a vertical velocity can enhance dynamo action, provid...

The internal seiche structure of a small, shallow lake (Frains Lake, Michigan) is shown to be dominated by the higher order vertical modes. The resonalit frequencies and the vertical velocity profiles of each mode were predicted from observed temperature profiles. The ohserved resonant frequencies and observed phase shifts in the velocity profiles of each mode corresponded closely to those pred...

Methodologies to improve disdrometer processing, loosely based on mathematical techniques common to the field of particle flow and fluid mechanics, are examined and tested. The inclusion of advection and vertical wind field estimates appears to produce significantly improved results in a Lagrangian hydrometeor trajectory model, in spite of very strict assumptions of noninteracting hydrometeors,...

In this article, the effects of viscous dissipation and inertial force on the velocity and temperature distributions of the mixed convection laminar flow in a vertical channel partly filled with a saturated porous medium have been studied. In this regard, the Brinkman–Forchheimer extended Darcy model was adopted for the fluid flow in the porous region. In addition, three different viscous dissi...

Chronic motor learning in the vestibuloocular reflex (VOR) results in changes in the gain of this reflex and in other eye movements intimately associated with VOR behavior, e.g., the velocity storage generated by optokinetic stimulation (OKN velocity storage). The aim of the present study was to identify the plastic sites responsible for the change in OKN velocity storage after chronic VOR moto...

The impact of two predictor variables (estimated knee extensor fast-twitch fiber percentage, body mass) on performance measures (vertical jump power output, leg press peak angular velocity) were examined. Subjects (25 men, 27 women) performed 5 workouts involving 2 vertical jump, leg press, and 50-repetition isokinetic tests (to estimate knee extensor fast-twitch fiber percentage). Multivariate...

The comparative study of aerobic power in different sports was conducted on 99 National Senior as well as National Junior players specialised in hockey and football, field games; volleyball and basketball, court games. The National Seniors were 27 hockey and 16 volleyball players, whereas, 32 football and 24 basketball players were the National Juniors. The maximal anaerobic power of the player...

The experiments described here explored how pilots want available maneuver authority information transmitted and how this information affects pilots before and after an aircraft failure. The aircraft dynamic variables relative to flight performance were narrowed to energy management variables. A survey was conducted to determine what these variables should be. Survey results indicated that bank...
