Développés par des ingénieurs, les modèles hydrologiques constituent une méthode d’anticipation du risque d’inondation en aménagement territoire. En simulant inondations futures, ils définissent champs possibles développement immobilier milieu urbain, où terrains disponibles à la construction sont rares. L’article examine l&#82...

Coursebooks are normally written to contain information, instruction, exposure, and activities that learn- ers at a particular level need to enhance their communicative competence in the target language. Howev- er, many global course books make attempts to include content, topics, and texts that do not disadvantage any learner around the world. That is why global course books normally do ...

A basic rule in computer architecture is that a processor cannot execute an application faster than it fetches its instructions. This paper presents a novel cost-eeective mechanism called the two-block ahead branch predictor. Information from the current instruction block is not used for predicting the address of the next instruction block, but rather for predicting the block following the next...

I BM's Writing to Read (WTR) Pro gram represents the largest direct corporate intervention in basic skills instruction currently imple mented in this country. It merits re view for two reasons: (1) many school districts may be considering purchas ing it, and (2) it has yet to be subjected to rigorous critique. According to an IBM brochure, "WTR is a computer-based instruc tional system designed...
