Recently, the number of applications developed for smartphones has dramatically increased; however, at the moment, applications having the purpose of creating and displaying 3D models are quite rare. The goal of this work is to build an application that allows the user to see the virtual three-dimensional representations of their friends and interact with them. The main challenge is to achieve ...

Solanum brasilianum Dunal was described by Dunal in 1813 with reference only to an illustration in an 18th century work by Leonard Plukenet. Th e plate is diffi cult to interpret and no explicitly related specimens were available so the name S. brasilianum has long been regarded as “unresolved” and has never been used. Material matching the Plukenet plate was discovered in the herbarium of the ...

In a study of surface branched coverings, one can ask naturally: In how many different ways can a given surface be a branched covering of another given surface? This problem was studied by many authors in Quart. J. Math. Oxford Ser. 2 46 (1995) 485, Math. Scand. 84 (1999) 23, Discrete Math. 156 (1996) 141, Discrete Math. 183 (1998) 193, Discrete Math. (in press), European J. Combin. 22 (2001) 1...

The effect of lossy earth on the far fi eld gain of antennas with finite s ize metal ground planes has been investigated experimen tally. Gain measurements were made of several antennas and their associated ground planes mounted both flu sh with the surface o f the ear th and far removed from the earth. It was found that for the ground plane sizes used in this study the gains for the two situat...

interlanguage pragmatics (ilp) has witnessed a growing body of research in the past two decades. one of the under-explored domains of l2 pragmatics is the role of learning strategies specifically tailored for the development of ilp knowledge. therefore, this investigation aimed to determine the significant interlanguage pragmatic learning strategies (ipls) used by high vs. low l2 pragmatic achi...
