abstract L-bases and B-bases are two important classes of polynomial bases used for representing surfaces in CAGD. The B ezier and multinomial bases are special cases of both L-bases and B-bases. We establish that certain proper subclasses of bivariate Lagrange and Newton bases are L-bases and certain proper subclasses of power and Newton dual bases are B-bases. A geometric point-line duality b...

supreme jurists have focused on sixth verse of sura tobeh to legitimize refuge in islam and assigned it to unbelievers. however, deliberating on other verses of holy quran, traditions and juristically regulations we can justify new issues which haven’t mentioned by supreme jurists. referring to the juridical books and various interpretations of holy quran to develop the concept of refuge this e...

the establishment of foreign military bases is a key matter to understand the distribution of power in spheres of influence throughout the world. oversea bases are the first mechanism of a mass network, which works to maintain the control exercised by great powers, becoming the infrastructure for wars. normally,  government allows the allies and governments that have similar ideas about common ...

This paper deals with continuous frames and continuous Riesz bases. We introduce continuous Riesz bases and give some equivalent conditions for a continuous frame to be a continuous Riesz basis. It is certainly possible for a continuous frame to have only one dual. Such a continuous frame is called a Riesz-type frame [13]. We show that a continuous frame is Riesz-type if and only if it is a con...
