The structure-activity relationships (SAR) are investigated by means of the Electronic-Topological Method (ETM) followed by the Neural Networks application (ETM-NN) for a class of anti-cholinesterase inhibitors (AChE, 53 molecules) being pyridazine derivatives. AChE activities of the series were measured in IC(50) units, and relative to the activity levels, the series was partitioned into class...

El presente reporte de investigación, presenta un recorte la tesis maestría del primer autor;tiene como objetivo analizar el trabajo matemático estudiantes carreras humanidades cuando resuelven una tarea sobre función exponencial. Para ello, nos fundamentamos en teoría Espacio Trabajo Matemático (ETM) y tomamos método ETM para análisis. La investigación se realizó con ciclo (16 18 años) univers...

Considering the external disturbances, in this paper, quasi-consensus of multiagent systems is studied via event-triggered impulsive control. By designing a novel mechanism (ETM), sufficient conditions to realize leader-following are derived with Additionally, Zeno behavior also excluded. It shown that frequency closely related parameters selected designed ETM, and less conservative results can...

The Ou River, a medium-sized river in the southeastern China, is examined to study estuarine turbidity maximum (ETM) response rapidly varied discharge, i.e., peak discharge (PRD). This analyzes difference ETM and sediment transport mechanisms between low-discharge PRD during neap spring tides by using Finite-Volume Community Ocean Model. three-dimensional model validated in-situ measurements fr...

Based on canonical correlation analysis the iteratively re-weighted multivariate alteration detection (MAD) method is used to successfully perform unsupervised change detection in bi-temporal Landsat ETM+ images covering an area with villages, woods, agricultural fields and open pit mines in North RhineWestphalia, Germany. A link to an example with ASTER data to detect change with the same meth...

Information about an area and its distribution of planted and harvested paddy rice field is essential for food security management, water resource management, and for the estimation of gas emissions. Rice field has specific coverage characteristics throughout its life time. Its coverage is mixed proportionally in accordance with its age, between water, soil, and rice vegetation. Landsat ETM+ ha...

The broad development of integrated heat and electricity systems (IHES) improved the energy utilization efficiency, but it also increased risk cascaded accidents difficulty operation. security region that defines permitted operation range is efficient for planning control IHESs, while accurate formulation boundary renders its applications. To address this problem, article first proposes a novel...

The accuracies of rice classifications determined from density slices of broadband moisture indices were compared to results from a standard supervised technique using six reflective Enhanced Thematic Mapper plus (ETM+) bands. Index-based methods resulted in higher accuracies early in the growing season when background moisture differences were at a maximum. Analysis of depth of ETM+ band 5 res...
