CRITICAL REMARKS ABOUT ENVIRONMENTALISM IMPLICATION BY IRANIAN SMES

Critical Remarks on "critical Remarks on Some Public-key Cryptosystems" by T. Herlestam

Tore Herlestam, in his note "Critical Remarks on Some Public-Key Cryptosystems", [5] suggests a method for attacking the RSA public-key cryptosystem. In this note we show that Herlestam's proposed attack is highly impractical, and that his analysis is erroneous. The RSA cryptosystem [1] encodes a message M using the key (e,n) via the equation: (1) C =E ~ ( M ) M e (modn) . Here the original mes...

The Factors Hindering Innovation at Iranian Smes

Innovation is the key to the economic development in today’s knowledge driven economy. World markets increasingly demand knowledge-intensive production and innovation-based competition. Iran still remains largely a natural-resource-based economy. To become competitive in today’s market it needs urgent shift towards a more knowledge-based economy which requires strong innovation system. This stu...

Remarks about Euclidean Domains

We will call (1) the d-inequality. Sometimes it is expressed in a different way: for nonzero a and b, if a|b then d(a) ≤ d(b). This is equivalent to the d-inequality, taking into account of course the different roles of a and b in the two descriptions. Examples of Euclidean domains are Z (with d(n) = |n|), F [T ] for any field F (with d(f) = deg f ; this example is the reason that one doesn’t a...

Remarks about Schlumprecht space

Let S denote the Schlumprecht space. We prove that 1. l∞ is finitely disjointly respresentable in S; 2. S contains an l1-spreading model; 3. for any sequence (nk) of natural numbers, S is isomorphic to the space ( ∑∞ k=1⊕ lnk ∞ ) S . Let (ei) ∞ i=1 be the standard basis of the linear space c00, the set of all finitely supported sequences. For x = ∞ ∑ i=1 aiei ∈ c00, suppx denotes the set {i ∈ N...
