Given a water-terrain area of interest (waterways, ports, etc.), this paper attempts to efficiently allocate underwater sonars to achieve a reasonable amount of coverage within a limited budget. Coverage is defined as the capability of sonars to detect threats. Though total coverage is desired, priority is given to the criticality/importance attached to the location of an area of interest on a grid-based system. Unlike other works in Read More

The presetation will overview the outcomes of the Irish Presidency of the EU Council for 2013 in addressing grand challenges for sustainable Growth with special emphasis on the digital (IT) agenda for Europe. The Irish Presidency of the EU council for 2013 made great achievements including the agreement of the 7 years EU Budget (including the budget to tackle youth unemploymen, the €70 billions Horizon 2020 p Read More

Understanding modern query languages provides key insights for the design of secure, effective and novel web applications. With the ever expanding volume of web data, two data shapes have clearly emerged as flexible ways of representing information: trees (such as most XML documents) and graphs (such as sets of RDF triples). Web applications that process, extract and filter such input data structures often re Read More

Recent developments in wireless communications and the emergence of high data rate services have consumed almost all the accessible spectrum making it a very scarce radio resource. Spectrum from very low frequencies to several GHz range has been either dedicated to a particular service or licensed to its providers. It is very difficult to find sufficient bandwidth for new technologies and services within accessible spectrum ra Read More

Spectral efficiency of a communication system refers to the information rate that the system can transmit reliably over the available bandwidth (spectrum) of the communication channel. Enhancing the spectral efficiency is without doubt a major objective for the designers of next generation wireless systems. It is evident that the telecommunications industry is rapidly growing due to the high demands for ubiquitous connectivi Read More

The traditional cycle in the simulation of the electron avalanches and any scientific simulation is to prepare input, execute a simulation, and to visualize the results as a post-processing step. Usually, such simulations are long running and computationally intensive. It is not unusual for a simulation to keep running for several days or even weeks. If the experiment leads to the conclusion that there is incorrect logic in the a Read More

The automated and simultaneous extraction of multiple phase distributions and their derivatives continue to pose major challenges. A possible reason is the lack of proper data processing concepts to support the multiple wave mixing that needs to be introduced to make the configuration at a time sensitive to multiple phase components and yet be able to decrypt each component of the phase efficiently and robustly, in abse Read More

Fault diagnosis (FD) has received much attention for complex modern automatic systems such as car, aircraft, rockets, unmanned vehicles, and so on since 1970s. In the FD research field, the diagnostic systems are often designed separately from the control algorithms, although it is highly desirable that both the control and diagnostic modules are integrated into one system module. Hence, the problem of simultaneous faul Read More

Automatic text correction has been attracting research attention for English and some other western languages. Applications for automatic text correction vary from improving language learning for humans and reducing noise in text input to natural language processing tools to correcting machine translation output for grammatical and lexical choice errors. Despite the recent focus on some Arabic language technologies, Read More

The Gas Electron Multiplier (GEM) has emerged as a promising tool for charged particle detection. It is being developed as a candidate detection system for muon particles for the future upgrade of Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC). It consists of a thin polymer foil, metal coated on each side and pierced by a high density of holes (see figure). The potential difference between the ele Read More
