Comparison of two automatic methods for measuring grazing behaviour

Evaluation of the RumiWatchSystem for measuring grazing behaviour of cows

Feeding behaviour is an important parameter of animal performance, health and welfare, as well as reflecting levels and quality of feed available. Previously, sensors were only used for measuring animal feeding behaviour in indoor housing systems. However, sensors such as the RumiWatchSystem can also monitor such behaviour continuously in pasture-based environments. Therefore, the aim of this s...

Comparison of two methods for measuring salivary cortisol.

To the Editor: The concentration of cortisol in the saliva reflects the activity of the hy-pothalamic-pituitary-adrenal axis (1), and an increased late-night salivary cortisol has Ͼ95% sensitivity and spec-ificity for Cushing syndrome (1, 2). We compared a commonly used modification of a RIA for serum cor-tisol with a new enzyme immunoas-say (EIA) specifically designed to measure salivary corti...

A comparison of two methods for measuring perceptual boundaries

This study investigates the performance of two experimental methods used for measuring perceptual boundaries. The first method is an adaptive procedure which allows the listener to arrive at a boundary by moving up and down in a stimulus continuum. The second method presents the listener with a list of stimuli taken from a continuum in randomized order. A listening test requiring short/long vow...

Deficit irrigation for corn: a comparison of two methods

Comparison of Two Methods for Automatic Brain Morphometry Analysis

The methods of computational neuroanatomy are widely used; the data on their individual strengths and limitations from direct comparisons are, however, scarce. The aim of the present study was direct comparison of deformation-based morphometry (DBM) based on highresolution spatial transforms with widely used voxel-based morphometry (VBM) analysis based on segmented highresolution images. We per...
