A wireless sensor network is a network consisting of spatially distributed, sometimeautonomous sensors, communicating wirelessly to cooperatively achieve some task. For example, a wireless sensor network may be used for habitat monitoring to ascertain the environment’s temperature, pressure, humidity, etc. In order for a wireless sensor network to provide such data, one needs to ensure there is...

This study examines the Kuznets environmental curve among D8 countries in the period 1961–2016. The Kuznets environmental curve shows the reversed U-shaped relationship between economic growth and environmental degradation. In this paper, two methods of time series estimation and smooth panel transition estimation were used to test the hypothesis of this relationship. Also, the ecological footp...

BACKGROUND Anatomic repair of tendon ruptures is an important goal of surgical treatment. There are limited data on the triceps brachii insertion, footprint, and anatomic reconstruction of the distal triceps tendon. HYPOTHESIS An anatomic repair of distal triceps tendon ruptures more closely imitates the preinjury anatomy and may result in a more durable repair. STUDY DESIGN Descriptive and...

The flux footprint probability distribution (FPD) for the near-surface receptor over a series of sinusoidal hills is evaluated using a backward Lagrangian stochastic (LS) model. The wind and turbulence fields derived from large-eddy simulations under unstable conditions, in which the synoptic wind aligns with the surface-elevation-varying direction, are used to drive the LS model. The character...

introduction development of studies on the urban, environment and conservation of natural resources, due to increase of urbanization as common lifestyles of citizens, has improved the sustainable urbanization approach that tries to improve  human interaction with nature for sound behavior. cities are the origins of consumerism and consequently irregular use of natural resources and energies. th...

A coupled Lagrangian random walk and atmospheric turbulence model was employed to investigate the magnitude of isoprene source distribution within a mixed deciduous forest canopy undergoing defoliation. Modeled source distributions were studied to understand how the flux footprint evolved as the total amount and vertical distribution of foliage changed during the leaf senescing and abscission p...

A growing body of literature discusses the CO2 emissions of cities. Still, little is known about emission patterns across density gradients from remote rural places to highly urbanized areas, the drivers behind those emission patterns and the global emissions triggered by consumption in human settlements—referred to here as the carbon footprint. In this letter we use a hybrid method for estimat...
