We consider a reaction-diffusion system of the KPP type in a shear flow and with a non-zero heat loss parameter. We establish criteria for the flame blow-off and propagation, and identify the propagation speed in terms of the exponential decay of the initial data. We prove existence of traveling fronts for all speeds c > max(0, c∗) in the case Le = 1, where c∗ ∈ R. That seems to be one of the f...

A stochastic solution is constructed for a fractional generalization of the KPP (Kolmogorov, Petrovskii, Piskunov) equation. The solution uses a fractional generalization of the branching exponential process and propagation processes which are spectral integrals of Levy processes.

This article investigates the security issues raised by the use of meta-programming systems with Java. For each possible type of MOP (compile-time, load-time, etc.), we study the permissions required for both the base and the meta-level protection domains, taking into account the flow of control between the different parts of the application. We show that the choice of a particular MOP architec...

This thesis describes the development of a rapid dielectrophoretic characterization tool for monitoring leukocyte activation, and its application for monitoring sepsis progression. Sepsis is an uncontrolled activation of the immune system that causes an excessive inflammatory response or an impaired immunity. The unpredictable immune status makes the immunotherapy treatment difficult. One cruci...

1 The fundamental goal of an electric utility is to serve its customers with a reliable and low cost power supply. This goal has led to a number of standard protection engineering practices that ensure adequate service; however, with deregulation of the utility industry and increased competitive pressures, there is a desire to further improve service reliability and reduce costs. In this vein, ...

In recent years, scholars and policy makers have questioned the extent to which the nation-state – specifically, the modern welfare state, marked by intervention and publicly-provided social protection – is compatible with economic globalisation. While transnational actors, including multinational corporations, institutional investors, banks and non-governmental organisations, undoubtedly influ...

There have been a number of studies that have sought to understand the pattern of aggregate business failure rates and model the macro-economic determinants of aggregate corporate liquidations in the UK. This paper uses quarterly data (1961.1-1998.2) on failure rates and potential macroeconomic determinants to build a time-series econometric model which explicitly tests for the impact of change...

A nondestructive optical method for determining the total solids content (TSC) and soluble solids content (SSC) of fresh whole prune (Prunus domestica L. ‘French’) was investigated. The method, based upon near infrared spectrophotometric techniques, could predict the TSC (r /0. 98, SEP /0.80% FW) and SSC (r /0. 96, SEP / 1.02%) of prunes. A low cost ($250

The predictions of Length-Of-Day (LOD) are studied by means of Gaussian Process Regression (GPR). The EOP C04 time-series with daily values from the International Earth Rotation and Reference Systems Service (IERS) serve as the data basis. Firstly, well known effects that can be described by functional models, for example effects of the solid Earth and ocean tides or seasonal atmospheric variat...

Intersection-collision warning systems use vehicle-to-infrastructure communication to avoid accidents at urban intersections. However, they are costly because additional roadside infrastructure must be installed, and they suffer from problems related to real-time information delivery. In this paper, an intersection-collision warning system based on vehicle-to-vehicle communication is proposed i...
