Any endeavor worth pursuing is worth measuring, but software security presents new measurement challenges: there are no established formulas or procedures for quantifying the security risk present in a program. This document details the importance of measuring software security and discusses the less-thansatisfying approaches that are prevalent today. A new set of metrics is then proposed for e...

A prediction model for methane production in a wastewater processing facility is presented. The model is built by data-mining algorithms based on industrial data collected on a daily basis. Because of many parameters available in this research, a subset of parameters is selected using importance analysis. Prediction results of methane production are presented in this paper. The model performanc...

Many canonical geometric structures have been found to be closely related to stability in the sense of geometric invariant theory. For the existence of Kähler-Einstein metrics, this is the classical conjecture of Yau [14, 15, 16]. The necessity of several notions of stability has been established in this case by Tian [12] and by Donaldson [3]. In the variational approach, the existence of Kähle...

We study the molecular evolution of insulin from metric geometry point of view. In mathematics, and in particular in geometry, distances and metrics between objects are of fundamental importance. Using a weaker notion than the classical distance, namely the weighted quasi-metrics, one can study the geometry of biological sequences (DNA, mRNA, or proteins) space. We analyze from geometrical poin...

Single-image super-resolution is of great importance for vision applications, and numerous algorithms have been proposed in recent years. Despite the demonstrated success, these results are often generated based on different assumptions using different datasets and metrics. In this paper, we present a systematic benchmark evaluation for state-of-the-art single-image super-resolution algorithms....

Web search results enjoy an increasingly greater importance in our daily lives. But what can be said about their quality, especially when querying a controversial issue? The traditional information retrieval metrics of precision and recall do not provide much insight in the case of the web. In this paper we examine new ways of evaluating quality in search results: coverage and independence. We ...

BACKGROUND The major cardiovascular risk factors and existing cardiovascular disease have been linked to increased risk of the frailty syndrome. However, the association between ideal cardiovascular health and the risk of frailty in older adults is uncertain. METHODS AND RESULTS Prospective cohort study of 1745 individuals (≥60 years and free of cardiovascular disease) recruited during 2008 t...

Role of packages in organization and maintenance of software systems has acquired vital importance in recent research of software quality. With an advancement in modularization approaches of object oriented software, packages are widely considered as re-usable and maintainable entities of objectoriented software architectures, specially to avoid complicated dependencies and insure software desi...

We show that spike timing adds to the information content of spike trains for transiently presented stimuli but not for comparable steady-state stimuli, even if the latter elicit transient responses. Contrast responses of 22 single neurons in macaque V1 to periodic presentation of steady-state stimuli (drifting sinusoidal gratings) and transient stimuli (drifting edges) of optimal spatiotempora...

‎In this paper we study Finsler metrics with orthogonal invariance‎. ‎We‎ ‎find a partial differential equation equivalent to these metrics being locally projectively flat‎. ‎Some applications are given‎. ‎In particular‎, ‎we give an explicit construction of a new locally projectively flat Finsler metric of vanishing flag curvature which differs from the Finsler metric given by Berwald in 1929.
