one of the most famous horticultural exporting products of iran is saffron. at present, the main region for the production of saffron is the northeast region of iran (khorasan-e razavi and southern khorasan provinces). the present research intends to survey the suitable areas for cultivation of saffron in the west of iran (kermanshah and kurdistan provinces) which, in the climatic conditions, i...

In [1] Adams constructed a non-nilpotent map v 1 : Σ S/2 −→ S/2. Using iterates of this map one constructs infinite families of elements in the stable homotopy groups of spheres, the v1-periodic elements of order 2. In this paper we work motivically over C and construct a nonnilpotent self map w 1 : Σ S/η −→ S/η. We then construct some infinite families of elements in the homotopy of the motivi...

Information security using chaotic dynamics is a novel topic in the wireless sensor network (WSN) research field. After surveying analog and digital chaotic security systems, we give a state of the art of chaotic S-Box design. The substitution tables are nonlinear maps that strengthen and enhance block crypto-systems. This paper deals with the design of new dynamic chaotic S-Boxes suitable for ...

To examine the behavior of microtubule-associated proteins (MAPs) in living cells, MAP 4 and MAP 2 have been derivatized with 6-iodoacetamido-fluorescein, and the distribution of microinjected MAP has been analyzed using a low light level video system and fluorescence redistribution after photobleaching. Within 1 min following microinjection of fluoresceinated MAP 4 or MAP 2, fluorescent microt...

Let L be a non empty relational structure. One can check that idL is monotone. Let S, T be non empty relational structures and let f be a map from S into T . Let us observe that f is antitone if and only if: (Def. 1) For all elements x, y of S such that x ¬ y holds f(x) ­ f(y). Next we state several propositions: (1) Let S, T be relational structures, K, L be non empty relational structures, f ...

In this article we prove the problem on isometric mappings of S posed by Th. M. Rassias. We prove that any map f : S → S, p ≥ n > 1, preserving two angles θ and mθ (mθ < π, m > 1) is an isometry. With the assumption of continuity we prove that any map f : S → S preserving an irrational angle is an isometry.

Abstract. This study proposes a novel structural self-organizing map (S-SOM) algorithm for synoptic weather typing. A feature of the S-SOM compared with traditional SOMs is its ability to deal input data spatial or temporal structures. In detail, search scheme best matching unit (BMU) in built based on similarity (S-SIM) index rather than by using Euclidean distance (ED). S-SIM enables BMU cons...
