Recent sensor development including high spatial resolution spaceborne systems like IKONOS as well as hyperspectral sensors like AVIRIS have the potential for more detailed and accurate mapping of urban land cover and land use. However, the new spaceborne sensors are limited in their spectral resolution with just four multispectral bands and few studies have focused on the issues of spectral pr...

One of the products to be derived from data acquired by theModerate Resolution Imaging Spectroradiometer (MODIS) onboard the National Aeronautics and Space Administration (NASA) Earth Observing System (EOS) will identify locations where land cover changes attributable to human activities are occurring. The product aims to serve as an alarm where rapid land cover conversion can subsequently be a...

Neuromyelitis optica (NMO) has been described as a disease clinically characterised by severe optic neuritis (ON) and transverse myelitis (TM). Other features of NMO include female preponderance, longitudinally extensive spinal cord lesions (>3 vertebral segments), and absence of oligoclonal IgG bands . In spite of these differences from multiple sclerosis (MS), the relationship between NMO and...

In this paper, we describe a new change detection method that determines the date at which land-use changes occur in a sequential series of Landsat TM images. We use this approach to extract annual rates of land conversion in the Pearl River Delta, China, for the period 1988-1996. The technique is a three-step change detection procedure that uses time series and panel econometric methods. First...

Herein, utilizing density functional theory (DFT) calculations, we have assessed the feasibility of single-atom-embedded C3N with various coordination environments TM-C3, TM-C2N1, TM-C4, and TM-C2N2 for oxygen electrocatalysis. It has been proved that most TM-CxNy candidates are stable all them possess metallic features to ensure fast electron transfer. Importantly, Co-C2N2 is a bifunctional no...

Studies carried out used different sensors and field applications can be accomplished to obtain information make decisions related coffee management. The objective of this work was train machine learning algorithms estimate the NDVI based on GreenseekerTM active optical sensor in 20 arabica cultivars experimental area National Institute Coffee Science Technology (INCT Coffee) using a passive RG...

In this paper, a bandpass frequency selective surface filter has been suggested for the satellite and radar applications at X band regime. The study conducted both numerically experimentally in wide range between 2 GHz 14 GHz. of 3 dB bandwidth 7.3 9.3 obtained. proposed structure polarization insensitive characteristic. It also angular stability with incident angle ranges from 0° to 60° very s...

We calculate analytically the probability density P (tm) of the time tm at which a continuous-time Brownian motion (with and without drift) attains its maximum before passing through the origin for the first time. We also compute the joint probability density P (M, tm) of the maximum M and tm. In the driftless case, we find that P (tm) has power-law tails: P (tm) ∼ t −3/2 m for large tm and P (...

The spatial and temporal distribution of land cover is a fundamental dataset for urban ecological research. An expert (or hypothesis testing) system has been used with Landsat Thematic Mapper (TM) data to derive a land cover classification for the semiarid Phoenix metropolitan portion of the Central Arizona-Phoenix Long Term Ecological Research (CAP LTER) site. Expert systems allow for the inte...
