The problem of identifying the source from observations from a Poisson process can be encountered in fault diagnostics systems based on event counters. The identification of the inner state of the system must be made based on observations of counters which entail only information on the total sum of some events from a dual process which has made a transition from an intact to a broken state at ...

We show that there are 5 formulas in the language of the Turing degrees, D, with ,_ and ^, that de…ne the relations x00 y00, x00 = y00 and so x 2 L2(y) = fx yjx00 = y00g in any jump ideal containing 0(!). There are also 6& 6 and 8 formulas that de…ne the relations w = x00 and w = x0, respectively, in any such ideal I. In the language with just the quanti…er complexity of each of these de…nition...

The structure of integrable field theories in the presence of jump defects is discussed in terms of boundary functions under the Lagrangian formalism. Explicit examples of bosonic and fermionic theories are considered. In particular, the boundary functions for the N = 1 and N = 2 super sinh-Gordon models are constructed and shown to generate the Backlund transformations for its soliton solution...

This work is devoted to stability analysis of numerical solutions for jump diffusions and jump diffusions with Markovian switching. Different from the existing treatment of Euler-Maurayama methods for solutions of stochastic differential equations, we use techniques from stochastic approximation. We analyze the almost sure exponential stability and exponential pstability. Then Markovian regime-...

Abstract: This paper studies the pricing of forward starting options under regime switching jump diffusion models. We suppose that a market economy has only two states, one is a stable state, the other is a high volatility state. The dynamics of a risky asset is modeled by a geometry Brownian motion when the market state is stable, otherwise, it follows a jump diffusion model. We propose two ty...

We present the results of an experimental investigation of the striking flow structures that may arise when a vertical jet of fluid impinges on a thin fluid layer overlying a horizontal boundary. Ellegaard et al. (1998, 1999) demonstrated that the axial symmetry of the circular hydraulic jump may be broken, resulting in steady polygonal jumps. In addition to these polygonal forms, our experimen...

The purpose of this study was to determine if an appropriate drop jump height for female athletes could be determined from squat and/or power clean maximums. Thirteen female collegiate basketball or volleyball players had their appropriate drop jump height determined by both maximal jump height (MJH) and reactive strength index (RSI) methods. The two methods often determined different appropria...

This paper continues the investigation into the relationship between good approximations and jump inversion initiated by Griffith. Firstly it is shown that there is a Π2 set A whose enumeration degree a is bad—i.e. such that no set X ∈ a is good approximable—and whose complement A has lowest possible jump, in other words is low2. This also ensures that the degrees y ≤ a only contain ∆3 sets and...
