Enhancement of MD-55-2 radiochromic film sensitivity using a multilayer film technique for applications in the low dose range

 ABSTRACTBackgrounds: MD-55-2 is one of the Radiochromic film models with the sensitivity suitable for dose measurements ranging from 5 to 100 Gy.  However, this lower limit makes the film impractical for its applications in many areas such as brachytherapy source dosimetry.Materials and methods: In this project, the useful range of the film has been extended by using a multilayer film techniqu...

GLRT Detector for NLOS Error Reduction in Wireless Positioning Systems

The objective of this paper is to determine the potentialities of an optimal detection scheme within the framework of subscriber location. Using a Generalized Likelihood Ratio Test (GLRT), an improved first arriving path detector from propagation channel estimates is derived. Furthermore, an expression for false alarm probability is provided and detector performance is evaluated for different c...

A Gsm Signals Based Positioning Technique for Mobile Applications

tropospheric error modeling for gps positioning

in this paper a practical method for tropospheric effects on gps derived coordinates in absolute mode is presented. gps observations at the permanent gps stations can be used as source of information for the modeling. the developed model is a time-dependent model and as such differs from usual tropospheric models, which are based on atmospheric parameters, i.e. temperature, pressure and humidit...

A New Sidelobe Reduction Technique For Range Resolution Radar

In radar and communication applications not only low time sidelobes but also uniform sidelobes are important. Polyphase codes have low sidelobes and are more Doppler tolerant, but correlated sidelobes are not uniform. New filters are modeled in this paper for polyphase codes to reduce the sidelobes and also to generate uniform sidelobes. Uniform sidelobe pattern is useful for detection of weak ...
