Arrival Delay Estimation in Bottleneck Section of Gyeongbu Line

Network Tomography, Delay Estimation & Bottleneck Link Discovery

An important issue in the measurement of networks is the ability to infer characteristics of internal network links from measurements made on end-to-end paths. It may be impractical in terms of equipment, time or cost to monitor each individual link but it is often feasible to monitor a number of existing paths. Provided there is enough traffic flowing through enough different paths then it is ...

Time-Delay Selection for Robust Angle of Arrival Estimation

prediction of ignition delay period in d.i diesel engines

a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...

Direction of Arrival Estimation

We have seen that there is a one-to-one relationship between the direction of a signal and the associated received steering vector. It should therefore be possible to invert the relationship and estimate the direction of a signal from the received signals. An antenna array therefore should be able to provide for direction of arrival estimation. We have also seen that there is a Fourier relation...

Direction of Arrival Estimation

Array Signal Processing (ASP) is a relatively new technique in Digital Signal Processing (DSP) with many potential applications in communication and speech processing. Direction of arrival (DOA) can be estimated using different techniques evolved with ASP. It is observed that subspace method provides superior performance in resolving closely spaced sources.
