through close scrutiny of the odessa steps sequence in sergei eisenstein's 1924 film, battleship potemkin, this article argues that the rhythmic editing of the film demands accompanying music based on the same rhythmic system. since eisenstein had a musical structure in mind for the editing of this sequence, composers of film music tasked themselves with expressing his rhythmic visual patt...

We define the well-known puzzle of Battleships as a decision problem and prove it to be NPcomplete, by means of a parsimonious reduction. By applying Valiant and Vazirani’s (1986) result we immediately obtain that the variant of this problem, viz. promising that there is a unique solution, is NP-complete as well, under randomized reductions. As this finding is in sheer contrast with the general...

Concept learning provides a natural framework in which to place the problems solved by the quantum algorithms of Bernstein-Vazirani and Grover. By combining the tools used in these algorithms—quantum fast transforms and amplitude amplification—with a novel (in this context) tool—a solution method for geometrical optimization problems— we derive a general technique for quantum concept learning. ...

Content Management Systems [1] are widely used in web sites and portals lately, promoting collaboration among groups of users. Collaboration applies to many fields and storytelling in the Web is one of them. When a group of users can contribute into telling a story the result could be apart from a more detailed story, an interesting educational method. Since the main purpose of a storyteller is...
