Non-empirical SCF molecular-orbital calculations of the d-orbital energies in the complexes [MnF,-,CI,]*( i = 1-6) and distorted [MnFGlk(k = 2 or 4) have been made within a valence-electron approximation. These energies have been shown to be accurately modelled by a one-electron angular-overlap Hamiltonian. The angular-overlap parameters for CI and F have a relationship which is similar to that...

The objective of this research was to evaluate species discrimination and specific age interactions in managed, homogeneous, even-aged Eucalyptus and Acacia plantations (4–11 years old) in KwaZulu-Natal, South Africa using hyperspectral data. CASI (36 bands; 426–952 nm spectral range; 1 m spatial resolution) radiance data from the spring (October) of 2004 were used to (i) discriminate between E...

Indonesian peatland, one of the world’s largest tropical peatlands, is facing immense anthropogenic pressures such as illegal logging, degradation and also peat fires, especially in fertile peatlands. However, there still is a lack of appropriate tools to assess peatland land cover change. By taking Pelalawan district located in Sumatra Island, this study determines number of land cover endmemb...

Given this model, spectral unmixing and endmember detection are the tasks of determining the endmembers and the proportions for every data point in the scene. Several endmember detection and spectral unmixing algorithms have been developed in the literature. However, the majority of these methods do not provide an autonomous way to estimate the number of endmembers and, thus, require the number...

It is necessary to monitor and identify mangroves types and spatial extent near coastal areas because it plays an important role in coastal ecosystem and environmental protection. This research aims at identifying and mapping mangroves types along Karachi coast ranging from 24.79 to 24.85 in latitude and 66.91 to 66.97 in longitude using hyperspectral remote sensing data and techniques. Image a...

Abstract The inconsistent response curve of delicate micro/nanofiber (MNF) sensors during cycling measurement is one the main factors which greatly limit their practical application. In this paper, we proposed a temperature sensor based on copper rod-supported helical microfiber (HMF). HMF exhibited different light intensity-temperature relationships in single-cycle measurements. Two neural net...

Quantification of water losses (WL) in distribution networks (WDNs) is a crucial task towards the development proper strategies to reduce them. Currently, WL estimation methods rely on semi-empirical assumptions and different implementation that increase uncertainty obtained estimates. In this work, we compare effectiveness robustness two widely applied approaches found international literature...

Geological mapping undoubtedly plays an important role in several studies and remote sensing data are of great significance geological mapping, particularly poorly mapped areas situated inaccessible regions. In the present study, Principal Component Analysis (PCA), Band Rationing (BR) Minimum Noise Fraction (MNF) algorithms applied to map lithological units extract lineaments Amezri-Amassine ar...

Interpretation of surface electromyograms (EMG) is usually based on the assumption that the surface representation of action potentials does not change during their propagation. This assumption does not hold for muscles whose fibers are oblique to the skin. Consequently, the interpretation of surface EMGs recorded from pinnate muscles unlikely prompts from current knowledge. Here we present a c...
