Influences of Buffer Size and Eb/No on Very Small Aperture Terminal (VSAT) Communictions

Ku-BAND SATELLITE TWO-WAY TIMING USING A VERY SMALL APERTURE TERMINAL (VSAT)"

The NBS Boulder Laboratory has recently completed installation of a 6.1 meter Ku-band (14/12 GHz) satellite earth station and has acquired two 1.8 meter portable earth terminals and commercial spreadspectrum modems. This equipment was procured for the purpose of doing two-way time transfer experiments in collaboration with other timekeeping laboratories. Each portable earth terminal, often call...

Very Small Size ka Band 6 Bit DMTL Phase Shifter Based on Combination of Capacitor and Resonator Type Methods

Abstract- Design and simulation of a very small size 6-bit DMTL phase shifter is presented. The idea is based on using both capacitor and resonator type methods simultaneously in a phase shifter. The capacitor section creates less significant bits. The bits in this section start from the least significant bit, with 5.625-degree steps. The resonator section creates the bits with 90-degree steps....

language learning strategies and vocabulary size of iranian efl learners

learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...

Effect of Geogrid Aperture Size and Soil Particle Size on Geogrid-Soil Interaction under Pull-Out Loading

Size Frequency Distributions for Very Small Craters on Mars

Introduction: Mars is a complex world, as has been increasingly revealed by the numerous missions to that planet during the past decade. Conclusions about the planet’s global geological processes of cratering and erosion (e.g. as reviewed by Chapman & Jones [1]), as inferred from early global imaging (e.g. Mariner 9 and Viking Orbiters) may retain some generalized credibility, but as the resolu...
