LIDAR is an optical remote sensing technology. An emitter sends out infrared laser pulses and the reflected light is detected by a photodiode. The distance and relative speed of other objects can be determined from the runtime of the signal (time of flight) and the speed of light. This measurement method is similar to radar. Both technologies offer similar ranges for similar applications but LI...

bivariate features, obtained from multichannel electroencephalogram (eeg) recordings, quantify the relation between different brain regions. studies based on bivariate features have shown optimistic results for tackling epileptic seizure prediction problem in patients suffering from refractory epilepsy. a new bivariate approach using univariate features is proposed here. differences and ratios ...

background: despite the relative success of surgical resection followed by proton, proton/photon, or conventional radiotherapy in terms of recurrence-free survival, chordomas are still associated with a high rate of recurrence. to our knowledge there are only very few reported cases of this rare tumor detected by f-18 fdg-pet. materials and methods: in this case we show the significance of f-18...

abstract the aim of this study, is to evaluate the effect of loss methods application on run-off volume and hydrograph shape used by hydrologic models. in this research, four loss methods including constant loss (φ index), initial loss-loss rate, scs and constant fraction approach were applied to be evaluated. to do this, clark rainfall-runoff model was applied for 24 storm events from kasilain...

This article has considered the volume and direction of Iran’s trade using the gravity model. The major issue in this analysis is to explore why Iran over or under-traded with the 76 countries relative to the predicted trade flows of the model. The study attempts to explore the reasons from the respect of both the model itself and Iran’s trade structure. This is done by analysing the performanc...

information technology (it) in the present era has affectedall aspects of organizations as a new strategy; therefore imagine anorganization without it and keeping abreast with new technologies seemsimpossible. the current research seeks to identify factors affecting theadoption of it innovation in governmental organizations. to this end theindices affecting it innovation adoption have been extr...

background: in recent studies, partial deletions of the azoospermia factor c region (azfc) on the y-chromosome have been detected in males with infertility problems. however, there has been a lot of debate about their significance. in order to study such deletions, a simple but accurate method for their detection was applied in this study. methods: we present data obtained from the multiplex li...

one of the important issues in the field of organizational decisions is determine the optimal time of use the equipment. managers should take proper decision to repair, rebuild or replace the equipment, so that the greatest benefit and the least cost to the organization. in the military, moving units, items, equipment and manpower, is the part of the logistics system mission. in this regard, th...
