The objective of this study is to develop models based on both optical and L-band Synthetic Aperture Radar (SAR) data for above ground dry biomass (hereafter AGB) estimation in mountain forests. We chose the site of the Loveh forest, a part of the Hyrcanian forest for which previous attempts to estimate AGB have proven difficult. Uncorrected ETM+ data allow a relatively poor AGB estimation, bec...

Carnosine is a dipeptide formed of the amino acids β-alanine and histidine. Only a limited number of studies have examined the effects of carnosine on sympathetic nerve activation and anxiety. The present study was undertaken to determine the dose-related effects of carnosine on anxiety in the elevated T-maze test (ETM) with electrodermal activity (EDA). Carnosine was injected in three groups o...

When performing post-classification comparison using images of different sensors, change detection is still possible even if images have different resolutions. However, in this case, change pixels are detected in the pixel size of coarser resolution image. This problem can be solved using higher resolution aerial photographs or panchromatic images if available. In multi sensor image fusion, ima...

Accurate knowledge of the spatial extents and distributions of an oil spill is very impor-tant for efficient response. This is because most petroleum products spread rapidly on the water surface when released into the ocean, with the majority of the affected area becoming covered by very thin sheets. This article presents a study for examining the feasibility of Landsat ETM+ images in order to ...

This paper is concerned with the nonfragile state estimation for a kind of delayed fractional-order neural network under event-triggered mechanism (ETM). To reduce bandwidth occupation communication network, ETM employed in sensor-to-estimator channel. Moreover, order to reflect reality, transmission delay taken into account model establishment. Sufficient criteria are supplied make sure that a...

This paper compares evapotranspiration estimates from two complementary satellite sensors - NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) and ESA's ENVISAT Advanced Along-Track Scanning Radiometer (AATSR) over the savannah area of the Volta basin in West Africa. This was achieved through solving for evapotranspiration on the basis of the regional energy balance equation, which wa...

An insu ciency of training data often results in a poorly learned classi er. To mitigate this problem, several learning methods using both labeled and unlabeled data have been proposed. In these methods, however, only static data are considered; time series unlabeled data cannot be utilized. In this paper, we rst present an extension of HMMs, named Extended Tied-Mixture HMMs (ETM-HMMs) in which...

Lippia alba (Mill.) N.E. Brown (Verbenaceae) is widely used in different regions of Central and South America as a tranquilizer. The plant's anxiolytic properties, however, merit investigation. The present study evaluated the effects of repeated daily (14 days) intraperitoneal (ip) treatment with an essential oil (EO) from a chemotype of L. alba (LA, chemotype II, 12.5 and 25 mg/kg; N = 6-8) an...

The potential of Landsat data processing to provide systematic continental scale products has been demonstrated by several projects including the NASA Webenabled Landsat Data (WELD) project. The recent free availability of Landsat data increases the need for robust and efficient atmospheric correction algorithms. This study compares the accuracy of two Landsat atmospheric correction methods: a ...
