A dynamic threshold sharing scheme is one that allows the set of participants to expand and contract. In this work we discuss dynamic threshold decryption schemes using bilinear pairing. We discuss and analyze existing schemes, demonstrate an attack and construct a significantly more efficient secure scheme.

We investigate generic models for cortical microcircuits, i.e. recurrent circuits of integrate-and fire neurons with dynamic synapses. These complex dynamic systems subserve the amazing information processing capabilities of the cortex, but are at the present time very little understood. We analyze the transient dynamics of models for neural microcircuits from the point of view of one or two re...

Simulcast Technique can be used to diminish handoff rate and share resources among multiple relays in MMR system. Using dynamic grouping, simulcast technique can also rearrange traffic load. In this paper, we analyze group handoff generated by dynamic grouping in MMR system. Performance is evaluated in view of blocking and handoff call dropping probability.

We consider the static and dynamic models of Cournot duopoly with tax evasion. In the dynamic model we introduce the time delay and we analyze the local stability of the stationary state. There is a critical value of the delay when the Hopf bifurcation occurs. Mathematics Subject Classification: 34K18, 47N10; Jel Classification: C61, C62, H26

Component-based design is widely used in embedded software design, where a new component can be generated by composing existing components. However a composition does not always generate a valid component. We define a composition to be valid with respect to a property if the composition preserves that property under certain context. In order to reason about whether a composition is valid, we ne...
