This paper proposes real-time interactive systems illuminating your shadows cast on the floor, which we name “Graphic Shadow.” They will make you experience an exciting space of interaction performing an illusion on your own shadow.

Probabilistic Latent Semantic Analysis (PLSA) is an effective technique for information retrieval, but it has a serious drawback: it consumes a huge amount of computational resources, so it is hard to train this model on a large collection of documents. The aim of this paper is to improve time efficiency of the training algorithm. Two different approaches are explored: one is based on efficient...

E-learning is a technology supposed to make learning and teaching easier. This paper deals with the question whether it is really true, i.e. if the same educational outcome consumes more or less time than classic teaching methods. From the observation flows that e-learning technologies, as well as other information and communication technologies, can consume inadequate time portion if used impr...

A dynamic programming algorithm to find an optimal alignment for a pair of DNA sequences has been described by Schöniger and Waterman. The alignments use not only substitutions, insertions, and deletions of single nucleotides, but also inversions, which are the reversed complements, of substrings of the sequences. With the restriction that the inversions are non-intersecting each other, their p...

We consider the problem of coordinating the exchange of real-time information among multiple agents. For example, a US Department of Transportation pilot program seeks to reduce tra c accidents by allowing each vehicle to request and send crash-relevant information (e.g. position, speed, braking status) from and to neighboring vehicles. Time is of the essence: vehicle information becomes stale ...

Spam messes up user’s inbox, consumes network resources and spread worms and viruses. Spam is flooding of unsolicited, unwanted e mail. Spam in blogs is called blog spam or comment spam.It is done by posting comments or flooding spams to the services such as blogs, forums,news,email archives and guestbooks. Blog spams generally appears on guestbooks or comment pages where spammers fill a commen...
