Recently Ramos and Mercère (2017a) presented a subspace system identification algorithm for 2-D purely stochastic state space models in the general Roesser form. However, since the exact problem requires an oblique projection of Y hf projected onto W h p along X̂ vh f , where W hp = [ X̂ vh p Y hp ] , this presents a problem since {X̂ vh p , X̂ vh f } are unknown. In the above mentioned paper, the ...

This News Report is a brief description of the 2010 Lifetime Achievement Award received by William (Bill) L. Ogren from the Rebeiz Foundation for Basic Research, at Champaign, Illinois, on Sep 10, 2011. It focuses mainly on the presentations by two of us (ARP and Gov), Christoph Benning (on behalf of Chris Somerville), David Krogmann and Jack Widholm, at this ceremony. It is enriched by the tes...

The convergence of communications and information technology within education, as well as more widely, means that concepts developed within ITS & AIED are now applicable to a wider range of wired, and more interestingly 'wireless', technologies. Interactive TV, supported by broadband broadcasting, offers interesting possibilities for education. The use of TV (and radio) in education has a long ...

We survey the evaluation methodology adopted in Information Extraction (IE), as defined in the MUC conferences and in later independent efforts applying machine learning to IE. We point out a number of problematic issues that may hamper the comparison between results obtained by different researchers. Some of them are common to other NLP tasks: e.g., the difficulty of exactly identifying the ef...

Copper (Cu) and mercury (Hg) enter aquatic ecosystems from different sources threatening health of aquatic organisms such as fish. As such, in this investigation, determinaing, Cu and Hg toxic concentration in Caspian roach (Rutilus rutilus caspicus), was undertaken. Acute toxicity of Cu and Hg were determined in fish specimen under semi-static condition. Caspian roach fry (~ 1 g) were exp...
