Long term defence planning is a complex undertaking involving many separate analytical steps and with non-trivial transitions from one step to the next. Many nations struggle with the challenge of establishing analytical rigour, structure and traceability in their defence planning processes. In this paper we will present a tool that has been developed not only to support defence planning, but w...

The Central Computing services at the Universiteit van Amsterdam (UvA) [17] have deployed an instance of the JASIG Uportal [18] system for use by a student audience of around 22,000. To achieve the requirement of a homogenous experience for the end user required a transition to a more consistent and unified Single Sign-On (SSO) and Single Sign-Off interaction with the underlying diverse infrast...

we give further results for perron-frobenius theory on the numericalrange of real matrices and some other results generalized from nonnegative matricesto real matrices. we indicate two techniques for establishing the main theorem ofperron and frobenius on the numerical range. in the rst method, we use acorresponding version of wielandt's lemma. the second technique involves graphtheory.

Context. Dynamos in the Sun and other bodies tend to produce magnetic fields that possess magnetic helicity of opposite sign at large and small scales, respectively. The build-up of magnetic helicity at small scales provides an important saturation mechanism. Aims. In order to understand the nature of the solar dynamo we need to understand the details of the saturation mechanism in spherical ge...

BACKGROUND Electrocardiographic (ECG) identification of prior myocardial infarction (MI) during right ventricular (RV) pacing is of clinical importance. Proposed ECG criteria have been evaluated only during apical pacing. We evaluated the effect of pacing site on the predictive performance of ECG signs of prior MI. METHODS The present study is a secondary analysis of a prospective, multicente...

The effect of a stochastic environment on an additive, two-locus model of a diploid population is examined. The appropriate diffusion equation is derived and its asymptotic properties are approximated by an Orstein-Uhlenbeck process. The first and second order moments of this approximating process are given. The mean linkage disequilibrium will be nonzero if the alleles at the different loci ar...

The objective of this effort was to examine the impact of TRSs on crashes, specifically total crashes, injury crashes, and specific crash types, such as right-angle and run stop sign crashes. The effort also included an economic analysis to investigate the tradeoffs between different crash types. It could be hypothesized that the major effect of TRSs would be to reduce instances of drivers fail...

Although quantum Monte Carlo is, in principal, an exact method for solving the Schrodinger equation, it is well-known that systems of Fermions still pose a challenge. Thus far all solutions to the “sign problem” [1] remain inefficient (or wrong). The fixed-node approach [2], however, is efficient, and in many situations remains the best approach. If only we could find the exact nodes—or at leas...

Iconicity is a property that pervades the lexicon of many sign languages, including American Sign Language (ASL). Iconic signs exhibit a motivated, nonarbitrary mapping between the form of the sign and its meaning. We investigated whether iconicity enhances semantic priming effects for ASL and whether iconic signs are recognized more quickly than noniconic signs are (controlling for strength of...
