Shannon defined an ideal (κ, n)-blockcipher as a secrecy system consisting of 2 independent n-bit random permutations. This work revisits the following question: in the ideal cipher model, can a cascade of several ideal (κ, n)blockciphers realize 2 independent n-bit random permutations, i.e. an ideal (2κ, n)-blockcipher? The motivation goes back to Shannon’s theory on product secrecy systems, a...

Türk edebiyatında edebî tür çalışmaları hayli sınırlıdr ve henüz gün yüzüne çıkmamış türler mevcuttur. Dolabnâmeler de bugün pek bilinmeyen bilinse bile yüzeysel tanımlamalarla tek bir kategoride bırakılmış türdür. Türkan Alvan Nihat Öztoprak’ın Dolabnâme isimli eseri dolabnâmelerin neden nasıl olduğu üzerine yoğunlaşarak dolabnâmeleri olarak literatüre kazandırır.

In recent years the longer working lives and the postponing of the retirement age have been topics of extensive discussion in Finland. Disability pensions play an important role in this debate. Working lives will lengthen if the incidence of disability retirement diminishes. Efficient actions can be focused on preventing disability retirement, if the groups at risk of disability retirement are ...

Let $R$ be a commutative ring with identity and $M$ be a unitary $R$-module. Suppose that $phi:S(M)rightarrow S(M)cup lbraceemptysetrbrace$ be a function where $S(M)$ is the set of all submodules of $M$. A proper submodule $N$ of $M$ is called an $(n-1, n)$-$phi$-classical prime submodule, if whenever $r_{1},ldots,r_{n-1}in R$ and $min M$ with $r_{1}ldots r_{n-1}min Nsetminusphi(N)$, then $r_{1...
