Use of the Hirsch-index (h) as measure of an author's visibility in the scientific literature has become popular as an alternative to a gross measure like total citations (c). I show that, at least in astrophysics, h correlates tightly with overall citations. The mean relation is h = 0.5(√ c + 1). Outliers are few and not too far from the mean, especially if 'normalized' ADS citations are used ...

A major challenge in process improvement is to understand process innovation and improvement efficiency and use. How do we know that process innovations and improvements give organizational benefits? We need a mechanism for measuring. In this paper, we report from a longitudinal action research study at the telecom company Ericsson where a measurement mechanism was designed and successfully use...

This paper re-examines the speech rhythm of Beijing Chinese and Pisa Italian by means of the Control/Compensation Index (CCI), with a view to normalizing the speech data, in order to reduce the effect of the rate factor. Two metrics were applied: (a) DnCCI, an adaptation to the CCI model of the nPVI normalization strategy; (b) SnCCI, a z-score normalization, which takes into account the actual ...

The necessity for software migration is presented. The concept of software migrator is introduced. A generality metric for software translations is proposed. The business feasibility of automated versus manual migration is studied. nTile PHPtoJava, a working software migrator, is reviewed.

Extract-Transform-Load (ETL) workflows are data centric workflows responsible for transferring, cleaning, and loading data from their respective sources to the warehouse. Previous research has identified graphbased techniques that construct the blueprints for the structure of such workflows. In this paper, we extend existing results by explicitly incorporating the internal semantics of each act...

Ns-2 and its successor ns-3 are discrete-event simulators which are closely related to each other as they share common background, concepts and similar aims. Ns-3 is still under development, but it offers some interesting characteristics for developers while ns-2 still has a large user base. While other studies have compared different network simulators, focusing on performance measurements, in...

When assessing child language development, researchers have traditionally had to choose between easily computable metrics focused on superficial aspects of language, and more expressive metrics that are carefully designed to cover specific syntactic structures and require substantial and tedious labor. Recent work has shown that existing expressive metrics for child language development can be ...

In the paper [29], N. Weaver introduced the notion of measurable metric and that of Lipschitz function with respect to such a metric. The study of these notions was pursued by the same author in subsequent papers ([30, 32, · · ·]) and in the book [31]. In our paper [16], we treated various important examples and, in particular, we studied the intrinsic measurable metric associated with a local ...

In this paper, we introduce and investigate a general transformation or change of Finsler metrics, which is referred to as a generalized β-conformal change: L(x, y) −→ L(x, y) = f(eL(x, y), β(x, y)). This transformation combines both β-change and conformal change in a general setting. The change, under this transformation, of the fundamental Finsler connections, together with their associated g...
