High spatial resolution images have been widely applied to the monitoring of land surfaces during the past decades.However, satellite and unmanned aerial vehicle (UAV) sensors (e.g., IKONOS, and QuickBird) usually only provide visible and near-infrared spectral bands with a high spatial resolution.Such limited spectral bands at a high spatial resol
Impact of recycled gravel obtained from low or medium concrete grade on concrete properties
This paper investigates the effect of recycled gravel obtained from low (Gl) or medium (Gm) concrete grade on fresh property of concrete (slump), mechanical properties (compressive-splitting tensile strength) and mass transport properties (ISAT-sorptivity) of concrete containing dolomite as a natural coarse aggregate.Concrete specimens were prepare
Trauma care and capture rate of variables of World Health Organisation data set for injury at regional hospitals in Tanzania: first steps to a national trauma registry
Abstract Background In Tanzania, there is no national trauma registry.The World Health Organization (WHO) has developed a data set for injury that specifies the variables necessary for documenting the burden of injury and patient-related clinical processes.As a first step in developing and implementing a national Trauma Registry, we determined how
A hybrid wavelet-Lyapunov exponent model for river water quality forecast
The use of spectral theory and chaos theory on river water quality modeling is reported in a very limited way.This study proposes a wavelet-maximum Lyapunov exponent (WMLE) Peak Attachment hybrid model for river water quality dynamics, combining spectral theory and chaos theory.The methodology involves the following major steps: (1) use of wavelet
