Several lines of evidence have confirmed that visual integrity among the two hemifields is severely impaired following transection of posterior part of the corpus callosum (splenium). But the extent of this impairment differs for various visual functions. Here, in a posterior callosectomized patient (MD), interhemispheric visual spatial integrity is investigated in three experiments. In the fir...

Geographical data are the core of any Geographical Information System (GIS) and any Geographic Information (GI) application. Because of the increasing use of decentrally held data and networked services, detailed knowledge about the existing data (i.e., its origin, structure, formats, quality, availability and reference applications) becomes more and more important. The availability of such met...

Passenger aircraft structural design is based on a safety factor of 1.5, and this safety factor alone is equivalent to a probability of failure of between 10 and 10. Yet airliners are much safer, with crashes due to structural failure being extremely rare based on accident records. The probability of structural failure of transport aircraft is of the order of 10 per flight segment. This paper l...

An inconsistency measure can be used to compare the quality of different datasets and to quantify the cost of data cleaning. In traditional relational databases, inconsistency is defined in terms of constraints that use comparison operators between attributes. Inconsistency measures for traditional databases cannot be applied to spatial datasets because spatial objects are complex and the const...

In database federations the integrity problem arises from the degree of heterogeneity and autonomy of participating component database systems. This causes integrity control more complicate than that in traditional centralized database systems. Semantic integrity should be considered in two phases: constraint federation and constraint enforcement. Otherwise, the administrators of component data...

Feature modeling is a technique for capturing commonality and variability. Feature models symbolize a representation of the possible application configuration space, and can be customized based on specific domain requirements and stakeholder goals. Most feature model configuration processes neglect the need to have a holistic approach towards the integration and satisfaction of the stakeholder’...

Using the RXTE/PCA data we study the fast variability of the reflected emission in the soft spectral state of Cyg X-1 by means of Fourier frequency resolved spectroscopy. We find that the rms amplitude of variations of the reflected emission has the same frequency dependence as the primary radiation down to time scales of 30−50 msec. This might indicate that the reflected flux reproduces, with ...

NAVSYS has developed a new Digital Antenna Element design for integration with a Controlled Reception Pattern Antenna (CRPA) which offers significant advantages over conventional Digital Antenna Electronics for high integrity GPS applications such as the Joint Precision Approach and Landing System (JPALS). Instead of performing spatial processing within the Digital Antenna Electronics, the Digi...

The layer-by-layer building methodology used within the powder bed process of Selective Laser Melting facilitates control over the degree of melting achieved at every layer. This control can be used to manipulate levels of porosity within each layer, effecting resultant mechanical properties. If specifically controlled, it has the potential to enable customisation of mechanical properties or de...
