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...

a knowledge of soil surface conditions, especially desert crust, salt crust and desert varnish is useful for improving classification of remotely sensed data. desert crust can generate high levels of reflectance, similar to those areas with high salt concentration and non-saline soil. therefore, soil surface crusts might bias thematic remote sensing of soils. in this study, we evaluated the eff...

This study aims at comparing the capability of different sensors to detect land cover materials within an historical urban center. The main objective is to evaluate the added value of hyperspectral sensors in mapping a complex urban context. In this study we used: (a) the ALI and Hyperion satellite data, (b) the LANDSAT ETM+ satellite data, (c) MIVIS airborne data and (d) the high spatial resol...

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...

Fugitive (or airborne) dust is a primary cause of decreased air quality, as well as being a potential health hazard. Urban and agricultural areas are of particular interest as fugitive dust sources because of their potential for releases during soil disturbance, ongoing industrial and commercial processes, and agricultural activities. Typical strategies for assessing and monitoring fugitive dus...

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...

The distribution of C3 and C4 vegetation plays an important role in the global carbon cycle and climate change. Knowledge of the distribution of C3 and C4 vegetation at a high spatial resolution over local or regional scales helps us to understand their ecological functions and climate dependencies. In this study, we classified C3 and C4 vegetation at a high resolution for spatially heterogeneo...
