In the present paper, we shall prove new characterizations of Berwald spaces and Landsberg spaces. The main idea inthis research is the use of the so-called average Riemannian metric.

topological indices are numerical parameters of a graph which characterize its topology. inthis paper the pi, szeged and zagreb group indices of the tetrameric 1,3–adamantane arecomputed.

Galois connection in category theory play an important role inestablish the relationships between different spatial structures. Inthis paper, we prove that there exist many interesting Galoisconnections between the category of Alexandroff $L$-fuzzytopological spaces, the category of reflexive $L$-fuzzyapproximation spaces and the category of Alexandroff $L$-fuzzyinterior (closure) spaces. This ...

We have added interaction from and to videos in our MathDox exercise system, by using the Popcorn.js library from the Mozilla foundation. Inthis weay we have realized interactive mathematical videos. Our approach is still in an experimental phase, but in the near future we will investigate the possiblities offered by this approach, both on technological and educational issues.

An important problem in Natural Language Processing is identifying thecorrect sense of a word in a particular context. Thus far, statistical methods have been considered the best techniques in word sense disambiguation. Unfortunately, these methods produce high accuracy results only for a small number of preselected words. The reduced applicability of statistical methods is due basically to the...

The application of pesticide is the best method to increase crops production yield. However it is also harmful to human health and the environment. The pesticides tested inthis study were Daconin, AntracolWP70 and Dithane M-45. They contain chlorothalonil, propined and mancozeb. A total of five soil samples were collected at 15 cm soil depth by systematic sampling.

In [1] we uniquely introduced ultra exponential functions (uxpa) and denednext step of the serial binary operations: addition, multiplication and power.Also, we exhibited the topic of limit summability of real functions in [2,3]. Inthis paper, we study limit summability of the ultra exponential functions andprove some of their properties. Finally, we pose an unsolved problem aboutthem.

the aim of this paper is to establish a fuzzy version of the dualitybetween domains and completely distributive lattices. all values aretaken in a fixed frame $l$. a definition of (strongly) completelydistributive $l$-ordered sets is introduced. the main result inthis paper is that the category of fuzzy domains is dually equivalentto the category of strongly completely distributive $l$-ordereds...
