When disturbances occur in power grid, monitoring, control and protection systems are required to stop the grid degradation, restore it to a normal state, and hence minimize their effects. However, in wide area power grid resulting from large extension and interconnection with neighbor grids, classical systems based on local independent measurements and decisions are not able to consider the ov...

We propose a new rendering system for large-scale, 3D geometic data that can be used with web-based content man-agement systems (CMS). To achieve this, we employed a geometry hierarchical encoding method “QSplat” and implemented this in a Java and JOGL (Java bindings of OpenGL) environment. Users can view large-scale geometric data using conventional HTML browsers with a non-powerful CPU and lo...

The idea of production of short-lived radioisotopes with the on-line technique has it roots in the early 1950s. In 1964 this became a reality when CERN approved an experiment at the 600MeV proton synchro-cyclotron, the SC. The first experiments were performed in 1967 and since then the ISOLDE programme has gradually developed into a major undertaking. Since 1992 the ISOLDE Radioactive Beam Faci...

This paper describes preliminary results from using an AI robot control software architecture known as T as the software framework for a procedure track ing system for the space shuttle Remote Manipula tor System RMS The system called TPT is de signed to track the expected steps of the crew as they carry out RMS operations detecting malfunctions in the RMS system from failures or improper con g...

This article highlights the problems of special vocabulary a certain sublanguage, approaches that allow identifying inventory linguistic signs. The authors examines structural and semantic model scientific technical terminology (based on terms electric power industry), which is simple exponent structure, for example, construction “a noun formed from transitive verb, or case implementation model...

In this paper we present a real-time active motion strategy for a mobile robot navigating in a non-flat terrain and its 3D constrained motion model. The aim is to control the robot with measurements from only one camera that autonomously builds a visual feature map while at the same time optimises its localisation within this map. The technique chooses the most appropriate commands maximising t...

Globally asynchronous locally synchronous (GALS) clocking applied to a system-on-a-chip (SoC) results in a design in which each core is a synchronous block (SB) of logic with a locally generated clock. Inter-core communication is asynchronous and controlled by wrapper logic around the cores. The nondeterministic synchronization used by most GALS architectures makes chip-level silicon debug and ...

Recent advances on synchro phasor measurement along with its regulation by the Operador Nacional do Sistema – ONS brought access to high resolution data rates up one sample per cycle. Electrical power system current, voltage, phase and frequency are collected through Phasor Measurement Units-PMUs stored in Data Concentrators PDCs. Such high-resolution favours new algorithms applications towards...
