the single wheel tester is an experimental device used to measure wheel forces when studying the relation of soil and wheel in a soil bin or in the field. in the model under development, a special frame holding the test wheel is connected to a loading carriage by two pairs of vertical rails and four rollers to provide a floating connection. by applying a driving torque to the test wheel shaft, ...

Recent studies have demonstrated that a quasi-steady model closely matches the instantaneous force produced by an insect wing during hovering flight. It is not clear, however, if such methods extend to forward flight. In this study we use a dynamically scaled robotic model of the fruit fly Drosophila melanogaster to investigate the forces produced by a wing revolving at constant angular velocit...

We examined responses from 91 single-neurons in the inferior colliculus (IC) of anesthetized guinea pigs to auditory apparent motion in the free field. Apparent motion was generated by presenting 100-ms tone bursts, separated by 50-ms silent intervals, at consecutive speaker positions in an array of 11 speakers, positioned in an arc +/-112.5 degrees around midline. Most neurons demonstrated dis...

The aim of the present experiments was to discern if the “entanglement”-like photon emissions from pairs of cell cultures or human brains separated by significant distances but sharing the same circling magnetic field could be demonstrated with a classic chemiluminescent reaction produced by hydrogen peroxide and hypochlorite. Simultaneous injection of the same amount of peroxide into a local d...

Human thumb and index finger kinematics were examined for multiple repetitions of a simple grasp task as a means to evaluate motor planning and execution of these important hand movements. Subjects generated a rapid (approximately 90-ms duration) pinch movement of the index finger and thumb from an open-hand position. Approximately 400 repetitions were obtained from four naive subjects. The two...

Males of two species of moths (Grapholitha molesta (Busck) and Hehothis virescens (F )) were flown in a sustained-flight tunnel in horizontal pheromone plumes The up-tunnel velocity of the moths increased with increasing height of flight and for G molesta was independent of tunnel wind velocities Use of moving ground patterns verified that the height of flight above the ground was the factor re...

We provide an overview of recent developments to the Hybrid Monte Carlo Simulation (HMS) model for calculating preequilibrium reactions. Illustrative examples are shown for nucleon and cluster induced reactions, and for assessing the importance of multiple preequilibrium processes. We present new results using HMS theory to study heavy nuclide recoil velocities, which are important in applicati...

Speech recognition by a small robot is difficult because the robot makes noise itself. In this paper, two new methods are proposed that suppresses internal noise of the small robots. These methods are based on spectral subtraction (SS). The difference of the proposed methods from the original SS is that the proposed methods use the estimated noise spectrum dependent on the motion of the robot. ...

The Hubble constant H0 should not show distancedependence. An inappropriate use of the direct Tully-Fisher relation may lead to a conclusion that H0 is dependent on the distance. This paper tries to answer the question: is it possible to avoid the caveats of the direct relation by applying the inverse Tully-Fisher relation. Under ideal conditions it is possible simultaneously to determine the i...
