basins leading to tabriz plain are part of the sub-basins of urmia lake basin, which is located in the east azerbaijan province and in the north-western part of iran. the area of this basin is 5397 km2, and agriculture is one of the main sources of income for the people, which is dependent on groundwater and surface water resources. in this study, an attempt was made to investigate the basins l...

BACKGROUND AND OBJECTIVES This study investigated whether the slope of estimated GFR is different between nonproteinuric subjects with and without diabetes, and what clinical factors are associated with the GFR slope. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS An observational cohort study was performed in 923 subjects, and the predictive value of baseline variables on the GFR slope was in...

In powertrain analysis, simulation of driveline models are standard tools, where efficient and accurate simulations are important features of the models. One input signal with high impact on the accuracy is the road slope. Here it is found that the amplitude discretization in production road-slope sensors can excite vehicle shuffle dynamics in the model, which is not present in the real vehicle...

This paper principally studies the prediction of slope deformation based on Support Vector Machine (SVM). In the prediction process,explore how to reconstruct the phase space. The geological body’s displacement data obtained from chaotic time series are used as SVM’s training samples. Slope displacement caused by multivariable coupling is predicted by means of single variable. Results show that...

A slope efficiency of 40% from an Er:LiYF4 laser is demonstrated under pulsed Ti:sapphire pumping at 973 nm. With reduction of the pump-pulse duration a significant decrease of the slope efficiency and an increase of the threshold is observed in the experiment and confirmed with high accuracy in a computer simulation. This behavior is due to interionic upconversion from the lower laser level, w...

Heavy seismic damage tends to occur in slopes when groundwater is present. The main objectives of this paper are to determine the dynamic response and failure mode of sandy slope subjected simultaneously to seismic forces and variable groundwater conditions. This paper applies the finite element method, which is a fast and efficient design tool in modern engineering analysis, to evaluate dynami...

introduction: the modis facility for the earth observing system is a key element that supports ambitious goals related to studying the earth as a system. one of the modis products is high quality land surface temperature data that product in terra and aqua platforms. knowledge of the lst provides information on the temporal and spatial variations of the surface equilibrium state and is of funda...

introduction: spatial variation of soil properties is significantly influenced by numerous environmental factors such as landscape features, including position, topography, slope gradient and aspect, parent material, climate and vegetation. soil properties vary spatially in south- and north-facing hill slopes. this factor (different slope aspects) can affect the distribution of soil organic mat...

We examine the impact of transmit antenna selection with receive generalized selection combining (TAS/GSC) for cognitive decode-and-forward (DF) relaying in Nakagamim fading channels. We select a single transmit antenna at the secondary transmitter which maximizes the receive signal-tonoise ratio (SNR) and combine a subset of receive antennas with the largest SNRs at the secondary receiver. In ...
