The proper selection of airflow measurement devices can be critical to the performance of today’s state-of-the-art HVAC system. Many of the requirements and limitations of one technology are often mistakenly thought to apply to every other. Not all technologies result in equal performance, even when used under similar conditions. Accuracy and repeatability vary between technologies and are most...

The goal of this paper is to provide a study on complementarity of feature point detectors. Many studies have been proposed on these detectors but none deals with complementarity in details. We introduce an evaluation of eleven well-known detectors based on new criteria used to characterize complementarity. The complementarity is computed with spatial distribution and contribution measures as w...

ludging from the recent literature, the problem of defining or analyzing the concept of omnipotence is a formidable one. One author has claimed to have proved the impossibility of defining omnipotencer and of those who have recently made the attempt, none has succeeded in providing a definition which is not subject to refutation by counter-example.' The leading and novel idea of our paper is th...

This paper describes the dynamics of capillary self-alignment of components with initial shift offsets from matching receptor sites. The analysis of the full uniaxial self-alignment dynamics of foil-based mesoscopic dies from pre-alignment to final settling evidenced three distinct, sequential regimes impacting the process performance. The dependence of accuracy, alignment time and repeatabilit...

Simulations have been a valuable and much used tool in networking research for decades. New protocols are evaluated by simulations. Often, competing designs are judged by their respective performance in simulations. Despite this great importance the state-of-the-art in network simulations is nevertheless still low. A recent survey [6] showed that most publications in a top conference did not ev...

The Coda Wave Interferometry (CWI) analysis serves to monitor the variation of propagation velocity in a heterogeneous medium with high precision (10−3% in relative terms). In combination with acoustoelastic theory, this type of analysis offers an NDT method for stress evaluation and/or damage detection. Since the CWI method is intended to evaluate extreme levels of accuracy, the presence of bi...

Despite many successes with teleoperated robotic surgical systems, some surgeons feel that the lack of haptic (force or tactile) feedback is detrimental in applications requiring fine suture manipulation. In this paper, we study the difference between applied suture forces in three knot tying exercises: hand ties, instrument ties (using needle drivers), and robot ties (using the da Vinci™ Surgi...

This paper provides a history of robotic guitars and bass guitars as well as a discussion of the design, construction, and evaluation of two new robotic instruments. Throughout the paper, a focus is made on different techniques to extend the expressivity of robotic guitars. Swivel and MechBass, two new robots, are built and discussed. Construction techniques of likely interest to other musical ...

PURPOSE To evaluate the repeatability and reproducibility of corneal power measurements obtained by Topcon KR-1W and iTrace, and assess the agreement with measurements obtained by Allegro Topolyzer and IOLMaster. METHODS The right eyes of 100 normal subjects were prospectively scanned 3 times using all the 4 devices. Another observer performed additional 3 consecutive scans using the Topcon K...
