The environmentalists of the entire world are crying by forecasting depletion biotic and abiotic resources at an accelerating rate which may make survival life on earth questionable. main cause this disastrous degradation is due to unmindful anthropogenic activities. present generation unaware consequences environmental need for conservation species their habitats. It imperative responsibility ...

We study the collective escape dynamics of a chain of coupled, weakly damped nonlinear oscillators from a metastable state over a barrier when driven by a thermal heat bath in combination with a weak, globally acting periodic perturbation. Optimal parameter choices are identified that lead to a drastic enhancement of escape rates as compared to a pure noise-assisted situation. We elucidate the ...

Valiant (2007) proposed a computational model for evolution and suggested that evolvability be studied in the framework of computational learning theory. Feldman (2008) showed that Valiant’s evolution model is equivalent to the correlational statistical query (CSQ) learning model, which is a restricted setting of the statistical query (SQ) model. Evolvability in Valiant’s model has been shown t...

Embedded systems usually have strict resource and performance constraints. Designers often need to improve the system design so that the system satisfies those constraints. In such case, performance bottlenecks should be identified and improved effectively. In this paper, we present a method to identify performance bottlenecks. Our method automatically identifies not only the bottlenecks but al...

We present MONITORMETHOD, a tool which helps Java programmers gain insight in the behavior of their applications. MONITORMETHOD instruments the Java application and relates hardware performance monitors (HPMs) to the methods in the Java application’s source code. We present a detailed case study showing that linking microprocessorlevel performance characteristics to the source code is helpful f...

The last successful invasion of Britain began in the summer of 2004. Like all evils, it stemmed from the continent, and quickly the invaders were rumoured to be smelly, to squat in houses by the thousands and to damage the livelihood of their autochthonous relatives. The invaders go by the harmlesssounding name of Harmonia axyridis or harlequin ladybird, but there is nothing harmonious or lady-...

process mining includes the automated discovery of petri nets from event logs. these event logs are the starting point for various discovery and analysis techniques of the process.  in this paper process model is developed using colored petri nets (cpns) and the supporting software package cpn tools. the restaurant process model is represented for the analysis using a combination of process min...
