Flow-based traffic measurement is a very challenging problem: Managing counters for each individual traffic flow in hardware resources knowingly struggle to scale with highspeed links. In this paper we propose a novel lattice theory-based approach that improves flow-based measurement performances and scales by keeping the number of the maintained hardware counters to a minimum (result mathemati...

Aiming at creating a dynamic between elaboration, realization, and validation by means of iterative cycles of experimentation, Future Internet Research and Experimentation (FIRE) projects have been rapidly confronted to the lack of systematic experimental research methodology. Moreover, the “validation by experimentation” objective involves a broad spectrum of experimentation tools ranging from...

Automotive sheet panel strain measurement usually involves large surface areas. For high resolution analysis, using the circle grid analysis method, several hundred elements must be measured. Existing technologies are limited to the small surface that area can be measured in one setup. As well, the (X,Y,Z) location on the part is not accurately available. This paper reports a new surface strain...

increasingly more of the func-tionality in today's telecommunication systems implemented in software, one of the most challenging tasks for PNOs is to assess the quality of the software in these systems and the capabilities of potential suppliers. In this article we describe the use of goal-oriented measurement and assessment as the basis for systematic quality improvements in software developm...

The tough competition among automotive companies creates a high cost pressure on the OEMs. Combined with shorter innovation cycles, testing new safety-critical functions becomes an increasingly difficult issue [4]. In the automotive industry about 55% of breakdowns can be traced back to problems in electronic systems. About 30% of these incidents are estimated to be caused by timing problems [7...

The purpose of this article is to provide a commentary on the current state of several measurement issues pertaining to curriculum-based measures of reading (R-CBM). We begin by providing an overview of the utility of R-CBM, followed by a presentation of five specific measurements considerations: 1) the reliability of R-CBM oral reading fluency, 2) issues pertaining to form effects, 3) the gene...

In measurement practice, the concept resolution is usually associated with the ability to distinguish two overlapping components of the same kind in observations. The original concept, Rayleigh’s well-known two-point resolution, stems from optics. It is based on the presumed limits of the human visual system to distinguish the images of two closely located point sources in observations of the s...

This paper explores the issues to be addressed to provide safe worst-case execution time (WCET) estimation methods based on measurements. We suggest to use structural testing for the exhaustive exploration of paths in a program. Since test data generation is in general too complex to be used in practice for most real-size programs, we propose to generate test data for program segments only, usi...
