This research has attempted to measure the parameters of barchan dunes as one of the desert landforms. This has been conducted by a field survey using cartographic techniques. In the field, two barchan dunes have completely been surveyed by total station equipment. Using the sample points a novel method has been devised to measure the barchans parameters. The method is mainly based on geom...

Background and Objectives In the present study, the Lut Desert, Iran was chosen as one of the hottest places in the world (with the recorded temperature of 70.7°C during 2003-2009) to find out whether any heat-resistant microorganisms were present in the soil. Materials and Methods The samples were collected from surface and depth of three identified places of Gandom Beryan in the Lut Desert....

analyses and thermal infrared channels 4 and 5 NOAA- AVHRR images. This research was carried out in Lut Desert located in center of sub-tropical divergence dominant in' Iranian plateau. The physical and thermal properties of the various desert surfaces have been determined using correlation relationships between the desert variables including: dark sand, normal sand, marl, saline soil, soil dep...

ABSTRACT Most previous studies of extreme temperatures have primarily focused on atmospheric temperatures. Using 18 years the latest version Moderate Resolution Imaging Spectroradiometer (MODIS) land surface temperature (LST) data, we globally investigate spatial patterns hot and cold extremes as well diurnal range (DTR). We show that world’s highest LST 80.8°C, observed in Lut Desert Iran Sono...

A Lookup‐Table (LUT) based design enhances the processing speed of a fuzzy obstacle avoidance controller by reducing the operation time. Also, a LUT sharing method provides efficient ways of reducing the LUT memory size. In order to share the LUT which is used for a fuzzy obstacle avoidance controller, an idea of using a basis function is developed. As applications of...

Following their fall to Earth, meteorites experience weathering. In this systematic study, we evaluate the trace element composition of ordinary chondrites from Antarctic cold desert, and Atacama (Chile) Lut (Iran) hot deserts, with an emphasis on rare earth elements (REE). Our data confirms that terrestrial weathering in deserts changes (Sr, Ba, REE, Hf, Th, U) concentrations. However, effects...
