Chronometric and imaging studies have shown that motor imagery is used implicitly during mental rotation tasks in which subjects for example judge the laterality of human hand pictures at various orientations. Since explicit motor imagery is known to activate the sensorimotor areas of the cortex, mental rotation is expected to do similar if it involves a form of motor imagery. So far, functiona...

Short Time Fourier Transform (STFT) is an important technique for the time-frequency analysis of a time varying signal. The basic approach behind it involves the application of a Fast Fourier Transform (FFT) to a signal multiplied with an appropriate window function with fixed resolution. The selection of an appropriate window size is difficult when no background information about the input sig...

Since the advent of digital image technology and remote sensing imagery (RSI), massive amount of image data has been collected worldwide. For example, since 1972, NASA and U.S. Geological Survey through the Landsat Data Continuity Mission, has been capturing images of Earth down to 15 meter resolution. Since image clustering is time-consuming, much of this data is archived even before analysis....

Mapping of landslides, quickly providing information about the extent of the affected area and type and grade of damage, is crucial to enable fast crisis response, i.e., to support rescue and humanitarian operations. Most synthetic aperture radar (SAR) data-based landslide detection approaches reported in the literature use change detection techniques, requiring very high resolution (VHR) SAR i...

hypertension crisis is one of the main health problems and its effective treatment is of high importance. for this purpose, fast-disintegrating and sustained release formulations of captopril, as a drug of choice, were prepared using conventional mucoadhesive polymers hydroxypropyl methylcellulose (hpmc), sodium carboxymethyl cellulose (na-cmc), hydroxypropyl cellulose (hpc), carbopol 934 (cp93...

high-resolution imagery such as ikonos satellite can produce useful information for many resource management applications. we investigated the capability of pan and multi spectral ikonos imagery of one region of tehran dated from 2005 in urban vegetation management and mapping of green cover. after data quality of images for radiometric noises, the images were geometrically corrected by polynom...

cognitive teaching methods facilitate the acquisition of motor skills; among these methods, the combination of physical, observational and imagery exercises has been the focus of recent investigations. the aim of this study was to investigate the facilitative effect of the combination of physical, observational and imagery exercises on immediate and delay retention of badminton high serve. the ...

The role of groundwater (GW) discharge on surface water (SW) quantity, quality and temperature is known to be important. Moreover, the effect GW contributions river thermal budgets critical in natural rivers considering that plays a vital fish survival during extreme heat events. identification zones with input can, thus, help management plans. However, detecting these at watershed scale can ch...
