The origin and nature of perturbations induced by a high-voltage pulse on plasma parameters their relationship to operating conditions (power pressure) in an argon inductively coupled radio frequency device is explored. are measured with two compensated Langmuir probes positioned either vertically above the pulsing target or horizontally along diameter chamber, same axial plane as distance from...

This paper presents a globally stable teleoperation control strategy for systems with time-varying delays that eliminates the need for velocity measurements through novel augmented Immersion and Invariance velocity observers. The new observers simplify a recent constructive Immersion and Invariance velocity observer to achieve globally convergent velocity estimation with only n+2 states, where ...

Aim: The aim of this study was to evaluate the influence of acrylic resin immersion in different mouthwashes on hardness, roughness and color. Methods: Specimens of an orthodontic selfcured acrylic resin (Orto Clas®) were produced and immersed in five mouthwashes: Plax® Classic (Colgate®); Plax® alcohol-free (Colgate®); Listerine® (Johnson & Johnson®); Periogard® (Colgate®) and Periogard® alcoh...

The objective of the study was to determine the influence of simulated microgravity by exposure to dry immersion on the craniomandibular system. Twelve healthy male volunteers participated in a 3-day dry immersion study. Before and immediately after exposure we measured maximal bite force using piezoresistive sensors. The mechanical properties of the jaw and cervical muscles were evaluated befo...

The use of miniature data loggers is rapidly increasing our understanding of the movements and habitat preferences of pelagic seabirds. However, objectively interpreting behavioural information from the large volumes of highly detailed data collected by such devices can be challenging. We combined three biologging technologies—global positioning system (GPS), saltwater immersion and time–depth ...

N*Vector (Networked Virtual Environment Collaboration Trans-Oceanic Research) is a project to develop innovative networked virtual reality technologies to support transoceanic collaboration [1]. The project is currently being conducted between Japan and the United States but the results are generalizable to other long-distance collaborative situations. In this paper we present one of the goals ...

We present a general model for default time, making precise the role of the intensity process, and showing that this process allows for a knowledge of the conditional distribution of the default only “before the default”. This lack of information is crucial while working in a multi-default setting. In a single default case, the knowledge of the intensity process does not allow to compute the pr...

The difference in the heating penetration characteristics of product processed in retort by steam-air application and water immersion was studied. Fresh milkfish (Chanos chanos) packed in dry pack and in oil medium, both in flexible pouches, was thermal processed to minimum F0 value of 7.77 at 121.1°C. Heat penetration values were recorded for each minute of processing with the aid Ellab (TM 96...

We give a fixed-parameter tractable (FPT) approximation algorithm computing the pathwidth of a tournament, and more generally, of a semi-complete digraph. Based on this result, we prove the following. • The Topological Containment problem is FPT on semi-complete digraphs. More precisely, given a semi-complete n-vertex digraph T and a digraph H, one can check in time f(|H|)n log n, where f is so...
