Horizontal structure function and vertical correlation analysis of mesoscale water vapor variability observed by airborne lidar [PDF]

, 2013
Analysis is presented of airborne lidar measurements of water vapor, covering a height range from 1.5 to 10.4 km, from three field campaigns (midlatitude summer, polar winter, and subtropical summer).

Upstream horizontal mergers, bargaining, vertical contracts [PDF]

, 2005
Contrary to the seminal paper of Horn and Wolinsky (1988), we demonstrate that upstream firms, which sell their products to competing downstream firms, do not always have incentives to merge horizontally. In particular, we show that when bargaining takes

Horizontal mergers and successive oligopoly [PDF]

This paper considers a successive oligopoly setting in which a set of upstream firms sell output non-exclusively to a group of downstream firms using a linear tariff.

Accuracy Analysis of GPS Positioning Near the Forest Environment

Croatian Journal of Forest Engineering, 2008
GPS has become an essential tool for georeferencing. In some cases, GPS is used for unfavorable conditions although it was developed for open field studies. This paper analyzes the achievable accuracy and performance of GPS near the forest.

Impairment of human spatial orientation in the horizontal, but not the vertical plane, due to aging, cognitive decline, or chronic peripheral vestibular loss

Frontiers in Aging Neuroscience
IntroductionHumans and other vertebrates exhibit anisotropic orientation and navigation skills, with better performances in the horizontal compared to the vertical plane. While horizontal navigation accuracy decreases with higher age, less is known about

Ground Truth in Classification Accuracy Assessment: Myth and Reality [PDF]

The ground reference dataset used in the assessment of classification accuracy is typically assumed implicitly to be perfect (i.e., 100% correct and representing ground truth).
