We study application of the Exponential Tilt Model (ETM) to compare survival distributions in two groups. The ETM assumes a parametric form for the density ratio of the two distributions. It accommodates a broad array of parametric models such as the log-normal and gamma models and can be sufficiently flexible to allow for crossing hazard and crossing survival functions. We develop a nonparamet...

Abstract. Glaciers of the Tista basin represent an important water source for mountain communities and a large population downstream. The article presents observable changes in Chhombo Chhu Watershed (CCW) glacier area basin, Sikkim Himalaya. CCW contains 74 glaciers (> 0.02 km2) with mean size 0.61 km2. We determined from declassified Hexagon Keyhole-9 (KH-9) (1975), Landsat 5 Thematic Mapp...

The Qinghai-Tibet Plateau is the largest lake area in China, with a total area of existing lakes of 36,900 km2, accounting for 49.5% of the total lake area of China The expansion and shrinkage of lakes in the Tibetan Plateau play critical roles in the water cycle and ecological and environment systems of the Plateau. In this paper, bases on the topographic map in 1970s, and the MASS and TM/ETM ...

Remote Sensing (RS) data and techniques, in combination with GIS and landscape metrics, are fundamental to analyse and characterise Land Cover (LC) and its changes. The case study here described, has been conducted in the area of Avellino (Southern Italy). To characterise the dynamics of changes during a fifty year period (1954÷2004), a multitemporal set of images has been processed: aerial pho...

In the westernmost region of the rapidly widening Corinth rift, Greece, extensive development of roads, bridges and other human infrastructure has caused continuous environmental change over the past twenty years. River networks, the land surface and the coastal environment, have been altered, especially in the areas corresponding to deltaic fans. In this paper we use earth observation systems ...

NASA and the US Geological Survey (USGS) are seeking to generate a map of the entire globe using Landsat 5 Thematic Mapper (TM) and Landsat 7 Enhanced Thematic Mapper Plus (ETM+) sensor data from the “mid-decadal” period of 2004 through 2006. The global map is comprised of thousands of scene locations and, for each location, tens of different images of varying quality to chose from. Furthermore...

* Corresponding author. Abstract – Recent improvements in sensor capabilities have enabled fire characterization from satellites. Instantaneous intensities of active fires have been characterized by the Fire Radiative Power (FRP), while burn severity has been assessed from the evaluation of Normalized Burn Ratios (NBR) derived from preand post-fire multispectral imagery. MODIS on the Terra and ...

The hydrologic networks play a paramount significance in paddy rice cultivation. The aerial photographs and satellite images, the latter were acquired from the Multispectral Scanner (MSS), Thematic Mapper (TM), Enhanced Thematic Mapper Plus (ETM+), and Operational Land Imager (OLI) were utilized to extract the fundamental information about the natural rivers and manmade canals over the past for...

The South Bali coast is prone to abrasion due its geographical position facing the Indian Ocean. High sea waves and currents in south of will erode beaches whose lithology morphology are abrasion. Land cover conditions that do not support coastal protection also affect high southern Bali. This study aims analyze shoreline changes from 1995-2021. analytical method used Digital analysis system (D...
