rangelands encompass 55% of iran's territory. monitoring of such resources is inevitable due to dynamic behavior and extremely high extension. scanning of land resources data by satellites facilitates monitoring the rangelands. this research was carried out to study the relationships of vegetation indices derived from irs liss-iii data with vegetation cover of tange sayyad region in the ch...

ecotones are zones of gradual changes from an ecological system to another.ecotones monitoring could be important to find out the reason for changes and limits. inthis research satellite data were used to analyze the ecotone boundary in fars steppicrangelands using irs liss iii and pan data of year 2006. the real vegetation map andecotones prepared through geo-eye images from google earth softw...

IRS-P6 spacecraft provides a unique opportunity of acquiring simultaneously multispectral (MS) data in three different spatial resolutions at 5.8 m, 23.5 m and 56 m, respectively, from LISS-4, LISS-3 and AWIFS sensors. Of these, spectral bands of the AWIFS (excepting the MIR band) have been designed to cover a 100% albedo, and with 10 bits per pixel to provide a good distribution of grey values...

The dynamic behaviors of water droplets on a slippery surface are significant to practical anti-icing applications. Herein, the impact and sliding behavior lubricant-infused surfaces (LISs) were investigated with high-speed camera. LISs prepared by infusing perfluoropolyether oils into anodized porous surfaces. results show that maximum spreading diameter retraction velocity droplet increased W...

In this work, we introduce the Linear Integer Secret Sharing (LISS) scheme, which is a secret sharing scheme done directly over the integers. I.e., the generation of shares is done by an integer linear combination of the secret and some random integer values. The reconstruction of the secret is done directly by a linear integer combination of the shares of a qualified subset of the parties. The...
