in this paper, we investigate duality of modular g-riesz bases and g-riesz basesin hilbert c*-modules. first we give some characterization of g-riesz bases in hilbert c*-modules, by using properties of operator theory. next, we characterize the duals of a giveng-riesz basis in hilbert c*-module. in addition, we obtain sucient and necessary conditionfor a dual of a g-riesz basis to be again a g...

Montgomery modular multiplication is used in cryptographic algorithms and digital signal processing application. The main objective is to reduce the delay and area of the Montgomery multipliers while maintaining low hardware complexity. To speed up, high-speed Montgomery modular multiplication algorithms and hardware architectures employ carry-save addition to avoid the carry propagation at eac...

A novel mechanism inspired by spider legs is presented and discussed in this paper. The mechanism has the potential to be used in future space applications, although the harsh space conditions, and in particular outgassing, should be carefully addressed in the design of a space-qualified model, The mechanism, called “Smart Stick”, has one degree of freedom and is actuated by a pressurised fluid...

Artificial systems are becoming more and more complex, almost as complex in some cases as natural systems. Up to now, the typical engineering question was “how do I design my system to behave according to some specifications”. However, the incremental design process is leading to so complex artifacts that engineers are more and more addressing a quite different issue of “how do I model the obse...
