Für kleine und mittelständische Unternehmen (KMU), die SoftwareProdukte herstellen, stellt sich kontinuierlich die Herausforderung, die Software wartund erweiterbar zu halten. Dabei müssen die Maßnahmen meist im laufenden Betrieb eingeführt werden und der Return of Investment (ROI) möglichst garantiert sein. Dieser Bericht beschreibt, mit welchen Schritten eine Testautomatisierung zu einer kont...

This paper applies dynamic programming principle and Legendre transform to study a dynamic asset allocation problem with liability process and stochastic interest rate model, where interest rate is assumed to be driven by the Ho-Lee model or the Vasicek model. By using variable change technique, we obtain the closed-form solutions to the optimal investment strategies in the quadratic utility fr...

A COMPARISON OF THE ROWE AND THE LEE MODELS FOR COMPLEX-VALUED FUNCTIONAL MAGNETIC RESONANCE IMAGING Zhaoyang Teng Marquette University, 2010 In 2005, Rowe published an fMRI magnitude and/or phase activation model that utilized both of the real and imaginary data in each voxel [1]. This model described the magnitude and phase time course as varying linearly with different design matrices where ...

We describe further improvements of the ηT pairing algorithm in characteristic three. Our approach combines the loop unrolling technique introduced by Granger et. al for the Duursma-Lee algorithm, and a novel algorithm for multiplication over F36m proposed by Gorla et al. at SAC 2007. For m = 97, the refined algorithm reduces the number of multiplications over F3m from 815 to 692.

In this paper we present an efficient methodology for approximating the distribution function of the net present value of a series of cash-flows, when the discounting is presented by a stochastic differential equation as in the Vasicek model and in the Ho-Lee model. Upper and lower bounds in convexity order are obtained. The high accuracy of the method is illustrated for cash-flows for which no...

Die Softwareentwicklung spielt inzwischen eine wichtige Rolle in vielen verschiedenen Industriezweigen – angefangen bei der Automobilindustrie über die Medizintechnik bis hin zur Automatisierungstechnik und zu vielen anderen Sparten. Die wachsende Komplexität der Systeme und folglich die ständig steigende Anzahl von Anforderungen an die Software führen zu höheren Ansprüchen an den Entwicklungsu...

In this paper, time-domain dynamic analysis of dam - infinite reservoir is studied. A numerical method, discrete singular convolution (DSC), which seems to be efficient and simple, has been used to model the mixed boundary conditions. After a brief introduction, DSC is applied to model the equation of motion of fluid-structure with constant cross section subjected to El-Centro (1940) earthquake...

The author suggests that dreaming cognition be modeled as reflecting dynamic, integrative, culturallysensitive, and historically holistic methods. The author conceptualizes six models of dreaming cognition. 1) Freudian dreaming model, 2) Jungian analytic model, 3) neurocognitive or neurophysiological dreaming model, 4) acculturative dreaming brain model (Sang Bok Lee, 2005: ”Lee Acculturation D...

This paper considers the role of norms within networks by describing how BP Exploration out-sourced its information technology (IT) function a major business activity. This outsourcing venture led to an attempt to create a network rather than to use a “market” form of organization. However, in some ways this attempt was found to have failed. It is suggested here that central to the effective fa...

We demonstrate here several previously unrecognized or insufficiently appreciated properties of the Lee-Carter mortality forecasting approach, a method used widely in both the academic literature and practical applications. We show that this model is a special case of a considerably simpler, and less often biased, random walk with drift model, and prove that the age profile forecast from both a...
