Compressors based on the Burrows Wheeler transform (BWT) convert the transformed text into a string of (move-to-front) ranks. These ranks are then encoded with an Ordermodel, or a hierarchy of such models. Although these rank-based methods perform very well, we believe the transformation to MTF numbers blurs the distinction between individual symbols and is a possible cause of inefficiency. Ins...

We consider the online list accessing problem and present a new family of competitive-optimal deterministic list update algorithms which is the largest class of such algorithms known to-date. This family, called Sort-by-Rank (sbr), is parametrized with a real 0 1, where sbr(0) is the Move-to-Front algorithm and sbr(1) is equivalent to the Timestamp algorithm. The behaviour of sbr() mediates bet...

This contrastive study, in the first place, examined the generic structure and, in the second place, explored the face theory proposed by Arundale (2006) in 140 doctoral dissertation acknowledgments written by native speakers of Persian (NSP) and native speakers of English (NSE) in 7 disciplines representing soft sciences to find out what discourse genre components writers employ to articulate ...

We characterize the class of strategy-proof social choice functions on the domain of symmetric single-peaked preferences. This class is strictly larger than the set of generalized median voter schemes (the class of strategy-proof and tops-only social choice functions on the domain of single-peaked preferences characterized by Moulin (1980)) since, under the domain of symmetric single-peaked pre...

The article summarizes and systematizes knowledge concerning natural user interfaces. The most important facts related to this problem have been supplemented with examples of possible practical use of such type of human-computer communication. Moreover, the article contains descriptions of three most popular controllers: Microsoft Kinect, Nintendo Wii and Sony Move.

Spooky Dodgeball at a Distance (or SDAAD for short) is a local multi player electronic game of virtual dodgeball without graphics. Two Players use a Neurosky MindWave headset, a lowcost EEG biosensor, and a PlayStation Move controller to defend and attack in a virtual game of dodgeball. The project is an exploration of the gameplay possibilities that these two different devices could offer when...

Background Granisetron is a first-generation 5-HT3-receptor antagonist that has shown efficacy in preventing postoperative nausea and vomiting (PONV). In this randomized double-blind parallel-group clinical trial, we assessed the efficacy of generic granisetron versus Kytril®, in the prevention of PONV in patients undergoing general anesthesia for gynaecological surgeries. Method One hundred an...
