Estimation Models for Software Functional Test Effort

The International Software Benchmarking and Standards Group (ISBSG) database was used to build estimation models for estimating software functional test effort. The analysis of the data revealed three test productivity patterns representing economies or diseconomies of scale and these patterns served as a basis for investigating the characteristics of the corresponding projects. Three groups of projects related to the three different productivity patterns, characterized by domain, team size, elapsed time and rigor of verification and validation carried out during development, were found to be statistically significant. Within each project group, the variations in test effort can be explained, in addition to functional size, by 1) the processes executed during development, and 2) the processes adopted for testing. Portfolios of estimation models were built using combinations of the three independent variables. Performance of the estimation models built using the function point method innovated by the Common Software Measurement International Consortium (COSMIC) known as COSMIC Function Points, and the one advocated by the International Function Point Users Group (IFPUG) known as IFPUG Function Points, were compared to evaluate the impact of these respective sizing methods on test effort estimation.

Electron Spin and Proton Spin in the Hydrogen and Hydrogen-Like Atomic Systems

Read full paper at: http://www.scirp.org/journal/PaperInformation.aspx?PaperID=52202#.VIj7tMnQrzE Author(s) Stanisław Olszewski * Affiliation(s) Institute of Physical Chemistry, Polish Academy of Sciences, Warsaw, Poland . ABSTRACT The mechanical angular momentum and magnetic moment of the electron and proton spin have been calculated semiclassically with the aid of the uncertainty principle for energy and time. The spin effects of both kinds of the elementary particles can be expressed in terms of similar formulae. The quantization of the spin motion has been done on the basis of the old quantum theory. It gives a quantum number n = 1/2 as the index of the spin state acceptable for both the electron and proton ...

Effects of Karate Training on Basic Motor Abilities of Primary School Children

“You never attack first in karate” might be the best conclusion of karate, which is a martial art practiced typically without weapons. It’s reported that karate has a long history for several hundred years, but the modern karate was spread to the whole Japan from Okinawa in the early part of 20th century. Now it has become one of the most widely practiced martial art forms in the world. Usually, it’s divided into Kihon, Kata and Kumite. As for the beginners, Kihon is more suitable for them because it involves basic techniques. Due to karate consists of dynamic offensive and defensive techniques using all parts of the body to their maximum advantage, the best understanding of true karate practice is the perfection of oneself through the perfection of the art. It not only develops coordination, quickens reflexes, and builds stamina, but also develops composure, a clearer thought process, deeper insight into one’s mental capabilities, and more self-confidence. So many researchers stu...

Fermented Brown Sugar Residue Prolongs the Caenorhabditis elegans Lifespan via DAF-16

Fermented brown sugar residue (FBSR) is generated in the course of purifying biomass ethanol from the yeast fermentation products of brown sugar. It contains abundant nutrition and is used in various industrial applications including as fertilizer and feed. Meanwhile, brown sugar has attracted attention as a health food and is thought to prevent cardiovascular diseases, hypertension, and brain stem diseases. Furthermore, polyphenol, contained in brown sugar, reduces oxidative stress and inhibits glucose absorption. DAF-16 is a transcription factor regulated downstream of the insulin signaling pathway and is one of the main factors contributing to aging and lifespan in C. elegans . Therefore, to determine the precise roles of the DAF-16 transcription factor in stress tolerance and life span, it is necessary to elucidate the signaling pathways involved in DAF-16 activation. This study was designed to elucidate the molecular mechanisms controlling the physiological stress toleran...
