Estimating the energy expenditure of farm animals at pasture is important for efficient animal management. In recent years, an alternative technique for estimating energy expenditure by measuring body acceleration has been widely performed in wildlife and human studies, but the availability of the technique in farm animals has not yet been examined. In the present study, we tested the potential...

A new path-planning algorithm for a motion simulator based on an industrial robot is introduced and compared with the classical washout filter. The algorithm calculates the path of the simulator cell via the solution of an optimization problem with constraints like the workspace of the simulator or maximum joint angle accelerations. Several test results are presented in order to validate the ne...

We address the pitfalls of averaging by exploiting the longitudinal variation in aid to identify sudden and sharp increases in aid flows. Focusing on specific events, we test if aid accelerations correspond to policies and shocks in the recipient country. For a large sample of 145 recipient countries and 33 donors from 19602007, we find that positive regime changes and wars are significant pred...

Equations of motion, in cylindrical co-ordinates, for the observed rotation of gases within the gravitational potential of spiral galaxies have been derived from Carmeli’s Cosmological General Relativity theory. A Tully-Fisher type relation results and rotation curves are reproduced without the need for non-baryonic halo dark matter. Two acceleration regimes are discovered that are separated by...

Controversy surrounds the risk of heading a soccer ball. The research objectives were to determine the statistical distributions of head accelerations during soccer heading for adult versus youth players, to compare results with known safe levels, and to suggest steps to reduce risk for children. Monte Carlo simulations of large numbers of head-ball impacts were done using equations of motion b...

To obtain kinematic accelerations with high accuracy and reliability, multiple Global Positioning System (GPS) receivers with a single antenna can be used for airborne gravimetry. The data collected from each receiver can be processed for kinematic accelerations that may be combined using simple averaging. Here, however, uncorrelated errors from instrument errors in each receiver also will be i...

In examining films of lifting movements in a study of the size-weight illusion (Davis & Roberts, 1976) a consistency was noted in the values obtained for the maximum accelerations of the objects lifted. While at first surprising, this finding can be embedded significantly in theories relating to kinesthetic illusions and the perception of weight and to theories on the control of general physica...

We explore logistic regression classifier (LogReg) and deep neural network (DNN) on the DCASE 2016 Challenge for task 3, i.e., sound event detection in real life audio. Our models use the Mel Frequency Cepstral Coefficients (MFCCs) and their deltas and accelerations as detection features. The error rate metric favors the simple logistic regression model with high activation threshold on both se...

Velocity measurements are presented for a vertically shaken granular layer. For frequencies around 110 Hz and accelerations larger than gravity, the layer develops a convective motion in the form of one or more rolls. The velocity of the grains near the wall has been measured. It grows linearly with the acceleration, then the growth rate slows down. A rescaling with the amplitude of the wall ve...
