Finite automata are backbones of the cryptosystems based on language theory. Most of the cryptosystems based on grammars and word problems are either insecure or do not satisfy digital signature prosperities. Basically, the cryptosystems based on automata are classified into cryptosystems based on: transducers, cellular automata and acceptors (i.e.

Dömösi’s cryptosystem [2, 3] is a new stream cipher based on finite automata. The cryptosystem uses specific deterministic finite accepters as secret keys for the encryption and decryption. Though this cryptosystem has been proven to be secure against different standard attacks (see [8]), the proposed encryption algorithms in [2, 3] involve exh

مما لا شك فيه أنَّ الإمام القرطبي كان من عباد الله الصالحين، الزاهدين في الدنيا، المشتغلين بما يعنيه من أمور الآخرة فيما بين توجه وعبادة، وكان مطرح التكلف، يمشي بثوب واحد؛ وعلى رأسه طاقية، ودر

Dӧmӧsi’s cryptosystem (Dӧmӧsi’s, 2008; Dӧmӧsi, November 11–14, 2009) is a new stream cipher based on finite automata without outputs. The cryptosystem uses specific deterministic finite accepters as secret keys for the encryption and decryption. Though this cryptosystem has been proven to be secure against different standard attacks (se

This paper presents a reminiscence of the Lesson Study through the eyes and perspective of the author and is narrated in three main stages - the past, the present and the future. It initially relates how Lesson Study started in Brunei. It then relates how it began to be accepted by the teachers due to strong support from the Brunei Ministry of Educ

Lesson study is being actively implemented in many countries as one of the continuous professional development programs for school teachers. Since collaboration is an important element of lesson study, it is deemed necessary to investigate teachers’ beliefs about collaboration in lesson study. Data were collected through both qualitative and quan

While Lean Manufacturing (LM) focuses on minimization of wastes, Green Manufacturing (GM) emphasizes on achieving zero emissions. Little is known about the linkage between these two initiatives and their integration. Furthermore, it is also not clear whether these two initiatives can coexist in the same organization or not. To address the gaps, thi

Lean Manufacturing (LM) is a thought developed in Toyota, thus, there is lack of studies investigated whether the implementation of LM is appropriate for different enterprises’ or not because of different organizational and social culture of enterprises and labor. This paper critically analyzes eleven prevailing models for LM in an attempt to fin
