Sensitivity to Time Delays in VDM-Based Navigation

Time Delays in Cosmic Ray Propagation

Cosmic Rays (CR) travel at speeds essentially indistinguishable from the speed of light. However whilst travelling through magnetic fields, both regular and turbulent, they are delayed behind the light since they are usually charged particles and their paths are not linear. Those delays can be so long that they are an impediment to correctly identifying sources which may be variable in time. Fu...

Context Sensitivity in Logical Modeling with Time Delays

For modeling and analyzing regulatory networks based on qualitative information and possibly additional temporal constraints, approaches using hybrid automata can be very helpful. The formalism focussed on in this paper starts from the logical description developed by R. Thomas to capture network structure and qualitative behavior of a system. Using the framework of timed automata, the analysis...

Delay Spoofing Reduction in GPS Navigation System based on Time and Transform Domain Adaptive Filtering

Due to widespread use of Global Positioning System (GPS) in different applications, the issue of GPS signal interference cancelation is becoming an increasing concern. One of the most important intentional interferences is spoofing signals. An effective interference (delay spoof) reduction method based on adaptive filtering is developed in this paper. The principle of method is using adaptive f...

Design of a Model Based Compensator for MIMO Systems with Time Delays and Constrained Inputs

Neural Sensitivity to Interaural Envelope Delays

Interaural time differences (ITDs) are important cues for mammalian sound localization. At high-frequencies, sensitivity to ITDs, which are conveyed only by the envelope of the waveforms, has been shown to be poorer than sensitivity to ITDs at low-frequencies, which are conveyed primarily by the fine-structure of the waveforms. Recently, human psychophysical experiments have demonstrated that s...
