Abstract

A study is made to estimate the amount of dust deposited on the leaf surfaces of ten plants species. The investigation provides a valuable idea of the relative dust capturing capacity of these species and underscores the importance of plants in mitigating dust pollution in the environment.

Abstract

Satellite imageries are the indispensable source of information for weather prediction. The image data from weather satellites is acquired in real time, but the preprocessing, information retrieval, and image products generation are generally implemented as offline activities to be carried out by the human experts. This work aims at generation of ready to use image products in real time. A Look-Up-Table (LUT) based method has been developed for encoding the processed information into the image. This paper describes the methodology employed to generate the Conventional Image Products in general and the Bispectral Hybrid Image Products in particular. On trial basis this method is being used in the automated system which is operational at Master Control Facility-Hassan, India to generate real-time, ready to use image products embedded with processed information. The resulting image is compared with the EUMETSAT (European Meteorological Satellite) image. The images taken by the spacecrafts, for the same day and same time were compared and it is found that there is a good agreement in the temperature ranges of the features represented in both the images.

Abstract

Platinum and tungsten have been widely used for making electrical contact using FIB for circuit edit. However they find limitation in small structure via filling. Molybdenum is becoming one of the promising materials to be used in FIB for electrical contact. Electrical characterization of FIB deposited molybdenum contact is described in this paper. Electrical resistivity, via filling capability, electro migration resistance and environmental resistance of FIB deposited molybdenum has been studied. FIB deposited molybdenum has shown better via filling capability and improved electro migration resistance. However molybdenum contacts are found to be susceptible to humidity induced degradation. Recapping the device after circuit edit with appropriate epoxy potting compound is found to provide excellent protection against humidity induced degradation.
