Diastolic Function Using 3-D Echo Reconstruction and Finite Element Analysis: Applications for Study in Animal Models and Patients
We have initiated animal experiments using three-dimensional reconstruction of echocardiographic recordings and finite element analysis to evaluate the effects of alterations in preload,...

Buckling of Frames with Load-Dependent Supports
The supports of frames may increase their rotational resistance as they are compressed. It is assumed here that this stiffening is a linear function of the load. Sway and nonsway buckling...

Rotational Failure Mechanisms Using Multiple Friction Circles

Effect of the Earth Rotation on Tide Induced Sediment Transport
Semi-enclosed seas are generally composed of narrow straits and wide basins, forming a strait-basin system. In the strait-basin system where tidal current prevails, the strong tidal current...

On-Site Rehabilitation Capabilities for the Nineties
This paper will review recent technological advancements in on-site manufacturing and machining capabilities which have been developed for the proper installation of new hydro turbines....

Long-Term Effects of Tillage and Crop Rotation on the Leaching of Nitrate and Pesticides to Shallow Groundwater
Contamination of groundwater by nitrate-nitrogen (NO3-N) and pesticides is a serious problem and concern in Iowa. The extent of contamination can...

Data Acquisition Techniques for Rotating Machinery
Monitoring the condition and performance of a hydraulic turbine or pump requires the simultaneous collection of data related to shaft speed, torque, power, water and airborne sound pressure...

Artificial Gravity Research Facility Options
On a long duration manned mission to Mars, the physiological changes caused by microgravity may be counteracted by artificial gravity. This paper evaluates several different classes of...

Hedratecture and Artificial Gravity
There is a need, according to the National Commission On Space, to develop three critical space facilities: A Space Base, A Variable-Gravity Research Facility, and a Lunar Surface Outpost....

Black Holes
For many years, scientists have searched the skies for black holes; stars even more massive than white dwarves. As of yet, there have been no 100% sure sightings. Since they do not emit...

Mudflow Rheology in a Vertically Rotating Flume
Joint research by the U.S. Geological Survey and the University of Missouri-Rolla currently (1990) is being conducted on a 3.05 meters in diameter vertically rotating flume used to simulate...

Rotating Hydraulics

Experiments on Baroclinic Eddy Evolution and Stability in Rotating Continuously Stratified Systems

The Effects of Rotation on Selective Withdrawal from a Density-Stratified Reservoir

Stratified Rotating Flow Past Isolated Obstacles

The Evolution of Cyclonic Disturbance and Lee Waves Over a Topography in a Rapidly Rotating Stratified Flow

Fatigue Design and Reliability Analysis of CFRP Composites
The statistical fatigue properties of unidirectional (UD) T800/3631 carbon/epoxy composite laminates are investigated in this paper. Fatigue tests were conducted under rotating bending....

Evaluation of the Rotation Capacity of Wide-Flange Beams Using Shell Finite Elements
Numerical simulation can be useful for planning of experimental tests, performance of parametric studies, and achieving an understanding of complex three-dimensional behavior that may...

Verification of Local Modes in a Two-Dimensional Tidal Model
Based on a generalized model equation, a two-dimensional hybrid finite element model has been developed to study tidal waves of incompressible, homogeneous fluid in rotational flows. In...

High-Resolution Two Dimensional Advective Transport
The paper describes a two-dimensional high-resolution scheme for advective transport that is based on a Eulerian-Lagrangian method with a flux limiter. The scheme is applied to the problem...
