In this paper we will survey some recent results on complexity theoretic model theory and algebra Essentially there are two major themes in this work The rst which we call complexity theoretic model theory deals with model ex istence questions For example given a recursive model A is there there a polynomial time exponential time polynomial space etc model B which is isomorphic to A The second ...

This paper examines the Macaulay, Hicks, and continuous time formulations of duration by analyzing the term structure dynamics that are necessary to derive these mathematical models. The results presented help to explain the true effects of interest rate risk upon the values of fixed-income securities, as well as provide a rationale for the development of duration models in a general equilibriu...

It is widely recognized that probabilistic graphical models provide a good framework for both knowledge representation and probabilistic inference (e.g., see Cheeseman94], Whit-taker90]). The dynamic behaviour of a system which changes over time requires an implicit or explicit time representation. In this paper, an implicit time representation using dynamic graphical models is proposed. Our go...

In a quantum field with spacetime invariance governed by the Poincaré algebra the one-loop effective action is equal to the sum of zero modes frequencies, which is the vacuum energy of the field. The first Casimir invariant of the Poincaré algebra provides the proper time Hamiltonian in Schwinger’s proper time representation of the effective action. We consider here a massive neutral scalar fie...

We clarify a discrepancy between two previous calculations of the two-loop QED Euler-Heisenberg Lagrangian, both performed in proper-time regularization, by calculating this quantity in dimensional regularization. e-mail address D.FliegnerThPhys.Uni-Heidelberg.De e-mail address M.G.SchmidtThPhys.Uni-Heidelberg.De e-mail address [email protected] Supported by Deutsche Forschungsg...

The problem of obtaining the error at the output of a neuro sliding mode controller is analyzed in this paper. The controller operates in discrete time and the method presented describes an error measure that can be used if the task to be achieved is to drive the system under control to a predefined sliding regime. Once the task specific output error is calculated, the neurocontroller parameter...

Representing human behavior and cognition, from individuals to societies, presents a range of challenges to the modeling and simulation community. A common thread through many of these challenges is formulating an authentic representation of time. Many of the issues related to time representation, from the sequencing of cognitive decision processes and information processing, to communication a...

The effects of testicular status and diet on the tenderness and flavour intensity of Omani lamb meat were evaluated. Thirty male lambs were divided into three testicular status treatments shortly after birth, entire, castrated or induced to cryptorchidism. The animals were fed a maize and soya bean meal based diet, isocalorically supplemented with either palm fronds or Rhodesgrass hay. The anim...
