Improvements in knowledge of satellite drag coefficients confirm current reports of a long-term decline in thermospheric density. Operational thermospheric models, though highly sophisticated, did not predict the extent of the decline, posing a problem for orbit control and maintenance. Evidence is presented that current models could not predict the magnitude of the decline for two reasons: (1) they do not ...

This report describes a project whose purpose is to develop a semi-pelagic trawl for squid and butterfish. Background of this fishery in New England is presented, as well as the constraints of the existing fleet. The approach used to meet the project objectives was the development of a rigging technique applied to a 156 x 80cm 4-seam bottom trawl. This ...

A description is presented of the design and construction of a solar electric commuter car-a practical commuting vehicle whose primary energy source is solar. A Sebring fiberglass kit car on a Volkswagen Beetle chassis was chosen for conversion to an electric vehicle with solar recharging capability. The 1600 lb two-passenger vehicle was equipped with a 25 hp peak DC brushless ...
Improvements in knowledge of satellite drag coefficients confirm current reports of a long-term decline in thermospheric density. Operational thermospheric models, though highly sophisticated, did not predict the extent of the decline, posing a problem for orbit control and maintenance. Evidence is presented that current models could not predict the magnitude of the decline for two reasons: (1) they do not realistically describe the highly variable energy entering the thermosphere from the solar wind at all times, especially at geomagnetically quiet times, and (2) they overestimate the less volatile ultraviolet contribution by ignoring eddy diffusion which transfers energy from the thermosphere to the mesosphere. The historical background of operational thermospheric models and suggestions for improvement are provided.
This report describes a project whose purpose is to develop a semi-pelagic trawl for squid and butterfish. Background of this fishery in New England is presented, as well as the constraints of the existing fleet. The approach used to meet the project objectives was the development of a rigging technique applied to a 156 x 80cm 4-seam bottom trawl. This novel technique included 5.5 meter droplines, a third set of bridles, and a flexible headrope kite. The rigging arrangement, however, could be applied to most bottom trawls. The net design and the model test results are reported, together with the results from instrumented sea trials and commercial use.
A description is presented of the design and construction of a solar electric commuter car-a practical commuting vehicle whose primary energy source is solar. A Sebring fiberglass kit car on a Volkswagen Beetle chassis was chosen for conversion to an electric vehicle with solar recharging capability. The 1600 lb two-passenger vehicle was equipped with a 25 hp peak DC brushless motor, a 5 kWh battery pack, and a 500 W/sub p/ solar cell array. The car meets the Pennsylvania safety inspection code for a passenger vehicle. Final design details and preliminary performance data are given.<>
A rough analysis of the scale effect as applied to a flying insect shows that the wing flapping frequency is inversely proportional to the square root of the size. The first two of the areas is used to design three simple structures. Aerodynamic calculations are made on the simplest structure. It is found that with a 0.5-mm chord, a 1-mm wing length and a 3- mu m thickness, it can generate 4.47*10/sup -7/ N of force, while its weight is 6.76*10/sup -8/ N, proving the feasibility of microrobot flight. Three large-scale models of flying microrobots are made with flapping frequencies in the range of 20 Hz. The influence of the flapping movement upon the whole structure is investigated.<<ETX>>
In this paper a detailed investigation has been carried out on the various design aspects of horizontal axis ocean current turbine (HAOCT). Performance characteristics of the turbine have been found through BEM theory and experiment. The investigations provide base line for the design and fabrication of commercial scale ocean current turbine. The analytical and experimental results are found to be in good agreement.
The spectra of effective dielectric constants which are proportional to dielectrophoretic force were investigated for a single protoplast of Ducaus carota in the range of 100 kHz to 50 MHz. The dielectrophoretic force was obtained by measuring the velocity of protoplast using an electrode which provides for a constancy in the dielectrophoretic force. The spectra show two or three peaks. In addition, the spectra washed in sucrose solution are found to be different from those washed and suspended in mannitol solution. the spectrum of the effective dielectric constants is obtained by measuring the impedance of a suspension in the range of 100 kHz to 10 MHz. The spectrum obtained is compared with that of the velocity measurement method.<<ETX>>
Constant power acceleration has been shown to extend the range of electric vehicles. However, this type of acceleration generally requires accelerations above a vehiclés maximum attainable acceleration when the vehicle is at low velocities. A practical approach is to accelerate at the maximum until a velocity is reached such that constant power acceleration from that point onward does not require accelerations larger than the maximum available. To implement this approach it is necessary to know the time at which to begin constant power acceleration and the constant power to use. This paper formulates and solves this problem.
Sea surface drag coefficient C<sub>D</sub> is fitted by four wind-wave parameters that are wave age, wave steepness, windsea Reynolds number R<sub>B</sub> and R<sub>H</sub> directly, with laboratory, field and combined data set. Comparison and analysis of dependence of C<sub>D</sub> on wind-wave parameters show that, among the four wind-wave parameters, windsea Reynolds number R<sub>B</sub> can fit the C<sub>D</sub> most appropriately.
