Reheating induced by competing decay modes [PDF]

Phys.Rev.D78:083539,2008, 2008
We address the problem of studying the decay of the inflaton field $\phi$ to another scalar field $\chi$ through parametric resonance in the case of a coupling that involves several decay modes. This amounts to the presence of extra harmonic terms in the perturbation of the $\chi$ field dynamics.

Checklists to Support Test Charter Design in Exploratory Testing [PDF]

arXiv, 2017
During exploratory testing sessions the tester simultaneously learns, designs and executes tests. The activity is iterative and utilizes the skills of the tester and provides flexibility and creativity.Test charters are used as a vehicle to support the testers during the testing.

On a proof of the collapse conjecture for a diagonal Bianchi type-IX vacuum space-time [PDF]

arXiv, 2011
It is given a simple proof of the collapse conjecture for a diagonal Bianchi type-IX vacuum space-time. It is shown that the codimension of the infinity stable attractor, restricted to the anisotropy plane, is not zero, thus proving that "escape along a channel" is impossible.

Patterns in Illinois Educational School Data [PDF]

, 2015
We examine Illinois educational data from standardized exams and analyze primary factors affecting the achievement of public school students. We focus on the simplest possible models: representation of data through visualizations and regressions on single variables.

Semilocal Generic Formal Fibers [PDF]

arXiv, 2003
Let T be a complete local ring and C a finite set of incomparable prime ideals of T. We find necessary and sufficient conditions for T to be the completion of an integral domain whose generic formal fiber is semilocal with maximal ideals the elements of C.

Characterization and parameterization of the singular manifold of a simple 6-6 Stewart platform [PDF]

arXiv, 2008
This paper presents a study of the characterization of the singular manifold of the six-degree-of-freedom parallel manipulator commonly known as the Stewart platform. We consider a platform with base vertices in a circle and for which the bottom and top plates are related by a rotation and a contraction.

Systematization of Vulnerability Discovery Knowledge: Review Protocol [PDF]

arXiv, 2019
In this report, we describe the review protocol that will guide the systematic review of the literature in metrics-based discovery of vulnerabilities. The protocol have been developed in adherence with the guidelines for performing Systematic Literature Reviews in Software Engineering prescribed by Kitchenham and Charters.

Enhancing Public Service Delivery through Organisational Modeling [PDF]

arXiv, 2016
Government organisations utilise a Citizen's Charter in order to furnish the public with comprehensive details of their service offerings that defines how their overall organisational goals are achieved. Studies on the implementation of Citizen's Charter in developing countries indicated that important social factors were not considered.

The "Days of Learning" Metric for Education Evaluations [PDF]

arXiv
The third National Charter School Study aimed to test whether charter school were effective and to highlight outcomes on academic progress. The results showed that typical charter school students outperformed similar students in noncharter public schools by 6 days in mathematics and 16 days in reading. The key metric used to claim better performance in

Exploratory Testing: One Size Doesn't Fit All [PDF]

arXiv, 2017
Exploratory testing (ET) is a powerful and efficient way of testing software by integrating design, execution, and analysis of tests during a testing session. ET is often contrasted with scripted testing, and seen as a choice between black and white. We pose that there are different levels of exploratory testing from fully exploratory to fully scripted
