The high precision attained by cosmological data in the last few years has increased the interest in exact solutions. Analytic expressions for solutions in the Standard Model are presented here for all combinations of Λ = 0 , Λ 6= 0, κ = 0 and κ 6= 0, in the presence and absence of radiation and nonrelativistic matter. The most complete case (here called the ΛγCDM Model) has Λ 6= 0, κ 6= 0, and...

We describe a simple analytic model for the magnetic field in the solar corona and interplanetary space which is appropriate to solar minimum conditions. The model combines an azimuthal current sheet in the equatorial plane with an axisymmetric multipole field representing the internal magnetic field of the Sun. The radial component of the field filling interplanetary space is approximately mon...

Model selection is one of the most important tasks in the identification of blackbox systems. In this paper, we give a novel model selection method from the viewpoint of functional analysis. We formulate the system identification problem as a function approximation problem in a reproducing kernel Hilbert space (RKHS), where the approximation error is measured by the RKHS norm. Within this frame...

In this paper we present an analytical model for charge injection in MOS switches that is valid for all regions of operation. The model is general and can be applied for different load conditions. We analyze and develop two separate charge injection models for the different operating conditions. A simple continuos model that is valid for all conditions is then stitched together using appropriat...

Credit decisions generally are based on judgments about the applicant derived from a report about a set of applicant attributes. Credit management does not directly observe applicant attributes. Instead the applicant provides a report of the relevant attribute set in the credit application. Unfortunately, those reports are not always perfectly reliable. In addition, attempts to clarify the repo...

Brooding over bosons, wave packets and Bose Einstein correlations, we find that a generalization of the pion-laser model for the case of overlapping wave-packets is analytically solvable with complete n-particle symmetrization. Multi-boson correlations generate momentum-dependent radius and intercept parameters even for static sources. Explicit multiplicity dependence of exclusive correlations ...

We develop a quantitative framework in order to understand how OR parallelism can be used to reduce execution times. In this model, tasks may either succeed or fail and any one success completes the problem. We follow Hoare and call these tasks “colluding”. We model the situation where tasks’ execution times are not known in advance, but instead have some probability distribution of execution t...

Abstract. We have developed a new semi-analytic model for the formation and evolution of structure on galaxy, group and cluster scales. The model combines merger trees with a detailed, spatially resolved description of the dynamical evolution of halo substructure. It reproduces the results of numerical simulations of mergers and halo formation at a fraction of the computational expense. We use ...

Background Coronary stenting appears to provide more predictable immediate results and lower rates of restenosis than conventional balloon angioplasty for selected lesion types, but its hospital costs are significantly higher. This study was designed to evaluate the potential cost-effectiveness of Palmaz-Schatz coronary stenting relative to conventional balloon angioplasty for the treatment of ...

Traditional transport service is either (1) reliable and ordered (e.g., TCP) or (2) unreliable and unordered (e.g., UDP). Some new computer applications such as multimedia do not t perfectly with either of these services. Partial Order Connection (POC), a new transport-layer protocol, tries to ll the gap between (1) and (2). With POC, an application speci es a partial order (PO) for valid order...
