One of the major problems in designing highly compact integrated circuits is power consumption circuits. Therefore, several technologies have been introduced to overcome facing MOSFET technology. these Quantum-Dot Cellular Atomata (QCA), which has advantages. In this paper, we focus on computational logic gates based T-Latch circuit. T-latch basis many circuit arithmetic unit (ALU). The propose...

introduction flood is an inevitable natural phenomenon occurring from time to time in all rivers and natural drainage systems, which not only damages the lives, natural resources and environment, but also causes the loss of economy and health. so estimation and prediction flood hazard is very important spatially in the watersheds without measurement station. there are many models in the water a...

Quantum Systems modeling and simulation activity is a challenging research area. Several models and applications were proposed in the past with different approaches. Special purposes models based on Cellular Automata (CA) paradigm were studied as the classical CA present limits in quantum system characterization. In this paper we derive a basic qualitative model, according to the Cellular Autom...
