Petri Net being one of the most useful graphical tools for modelling complex asynchronous systems, we have used Petri Net to model multi-track railway level crossing system. The roadway has been augmented with four half-size barriers. For better control, a three stage control mechanism has been introduced to ensure that no road-vehicle is trapped on the level crossing. Timed Petri Net is used t...

It is notable that level crossing rate, outage probability and average time of fade duration of the combiner output signal are very important system performances. In this paper the level crossing rate, outage probability and fade duration of the SSC combiner output signal in the presence of the Nakagami-m fading are determined. The results are shown graphically for different variance values, de...

A novel approach of combining the practical appeal of Kalman filtering with the design of an optimal alarm system for the prediction of level-crossing events was introduced in earlier work. Here, the aim is to perform a more detailed extreme value analysis using the critical threshold that enables definition of the level-crossing event. It will be rigorously proven that the approximations and b...

We study the level crossing in the energy spectrum due to Rashba-Dresselhaus spinorbit coupling in nanowires modulated by longitudinal potential. By implementing both an analytical methodology and a numerical technique based on the finite element method (FEM), we show that the level crossing point can be manipulated with the application of spin-orbit coupling in parabolic nanowires. In particul...

Clustered graphs are an enhanced graph model with a recursive clustering of the vertices according to a given nesting relation. This prime technique for expressing coherence of certain parts of the graph is used in many applications, such as biochemical pathways and UML class diagrams. For directed clustered graphs usually level drawings are used, leading to clustered level graphs. In this thes...

The present work deals with the automatic detection of the sleep stages from the singlechannel EEG data. Various stages of sleep are Awake, sleep stage 1, 2, 3 and 4 and rapid eye movement. Statistical attributes are extracted with the help of Ensemble Empirical Mode Decomposition, Hjorth parameter and zero-crossing rate. Ten-cross fold classification process is followed after best ranked attri...

By using a second quantized formulation of level crossing, which does not assume adiabatic approximation, a convenient formula for geometric terms including offdiagonal terms is derived. The analysis of geometric phases is reduced to a simple diagonalization of the Hamiltonian in the present formulation. If one diagonalizes the geometric terms in the infinitesimal neighborhood of level crossing...
