The reflection of an object can be distorted by undulations of the reflector, be it a funhouse mirror or a fluid surface. Painters and photographers have long exploited this effect, for example, in imaging scenery distorted by ripples on a lake. Here, we use this phenomenon to visualize micrometric surface waves generated as a millimetric droplet bounces on the surface of a vibrating fluid bath...

The present paper aims to highlight certain relevant and new features revealed by the research on assisted training. The motivation is given by the necessity to efficiently develop the educational resources by combining reusable learning objects, and also by the need to customize training in order to meet specific user options. The main objective is to design a flexible framework for assembling...

We developed a Web-based application delivered on PDAs (Colecta-PALM in Peru, Pambazuko-PALM in Kenya), to collect data from HIV patients and to facilitate HIV provider training. Colecta-PALM provides tailored feedback (behavioral messaging) based on risk assessment responses for HIV patients. Pambazuko-PALM collects patient risk assessment data, and delivers counseling protocol training and ev...

The objective of this research was to assess the effectiveness of adaptive automation (AA) for supporting information processing (IP) in a complex, dynamic control task by defining a measure of situation awareness (SA) sensitive to differences in the forms of automation. The task was an air traffic control (ATC)-related simulation and was developed to present four different modes of automation ...

We propose two time delay estimators for known symbol padding (KSP) orthogonal frequency division multiplexing (OFDM) in a multipath fading environment. Both estimators make use of pilot symbols in the guard interval and known pilot carriers and take the frequency selectivity of the channel into account. The performance of the estimators is illustrated by means of simulation results for the mea...

In this paper we propose a simple, yet flexible and efficient, channel estimator for the uplink in broadband Orthogonal Frequency Division Multiplexing (OFDM) systems. The processing is performed in the time-domain, by extracting the channel’s impulse response (CIR) for each user from a joint training signal. In this OFDM system, the pilot sequence we advocate, where all users share the same pi...

INTRODUCTION In Japan, Pilot Plant of the HIDiC was built in 2005. It was commercial base scale and already achieved the consecutive distillation for 1000 hours. The energy consumption of the pilot HIDiC was only about 70% of that of a conventional distillation column. The HIDiC can lower reboiler and condenser load by heat exchange between rectifying section and stripping section. Therefore, i...

In this paper, global optimisation and nonlinear simulation are used to search for the worst-case control demands which may be input by a pilot flying a modern high performance aircraft with a full authority flight control law. The flexibility of global optimisation is exploited to simultaneously search for worst-case pilot inputs and worst-case combinations of uncertain parameters in the nonli...

STOCK DEFINITION AND GEOGRAPHIC RANGE There are two species of pilot whales in the Western Atlantic: the Atlantic or long-finned pilot whale, Globicephala melas, and the short-finned pilot whale, G. macrorhynchus. These species are difficult to identify to the species level at sea; therefore, some of the descriptive material below refers to Globicephala sp. and is identified as such. The specie...

STOCK DEFINITION AND GEOGRAPHIC RANGE The short-finned pilot whale is distributed worldwide in tropical to warm temperate waters (Leatherwood and Reeves 1983). There are two species of pilot whales in the western North Atlantic the Atlantic or long-finned pilot whale, Globicephala melas, and the short-finned pilot whale, G. macrorhynchus. These species are difficult to differentiate at sea; the...
