Practical aspects of designing microstrip-slot couplers on an AI ~03 ceramic substrate (e, = 9.8) are treated in supplementation of the theoretical analysis of the coupler presented in Part I. Comparison with implemented couplers yields rules for specification of the reference planes at the ends of the coupling section and for the appropriate choice of definition for the slot-line characteristi...

Input saturation is inevitable in many engineering systems. In this note, the focus is to design the proper iterative learning control algorithms when the desired trajectory cannot be realized within the saturation bound. Two new algorithms are proposed. First algorithm introduces a kind of “reference governor” which reduces the amplitude of the desired trajectory systematically such that the m...

We consider a notion of sequential functional of -nite type, more generous than the familiar notion embodied in Plotkin’s language PCF. We study both the “full” and “e4ective” partial type structures arising from this notion of sequentiality. The full type structure coincides with that given by the strongly stable model of Bucciarelli and Ehrhard; it has also been characterized by van Oosten in...

Trajectory tracking of nonlinear dynamical systems with affine open-loop controls is investigated. The control task is to enforce the system state to follow a prescribed desired trajectory as closely as possible. We introduce exactly realizable desired trajectories as these trajectories which can be tracked exactly by an appropriate control. Exactly realizable trajectories are characterized mat...

In the Graph Realization Problem (GRP), one is given a graph G, a set of non-negative edge-weights, and an integer d. The goal is to find, if possible, a realization of G in the Euclidian space R, such that the distance between any two vertices is the assigned edge weight. The problem has many applications in mathematics and computer science, but is NP-hard when the dimension d is fixed. Charac...

The following major aspects of the problem of Input–Output Triangular Decoupling (TD) for general neutral multi–delay systems, via proportional realizable state feedback, are resolved for the first time: The necessary and sufficient conditions for the problem to have a realizable solution and the general analytical expressions of the proportional realizable TD controller matrices. The condition...

The impact of capital mobility restrictions on the diversification benefit for risk at the group level of a financial conglomerate is an important aspect in risk management. In this paper we propose a new bottom-up approach for realizing diversification benefits using some predetermined capital and risk transfer instruments, taking counter-party default risk into account.

Given a sequence φ = (φn) of non-negative integers, we examine two related questions about dynamical realizations of φ. The sequence is exactly realizable if there is a dynamical system (X, T) (a homeomorphism of a compact metric space) for which fn(T) = #{x ∈ X | T n x = x} = φn for all n ≥ 1, and is realizable in rate if there is a dynamical system (X, T) for which fn(T)/φn −→ 1 as n → ∞. We ...

In the setting of universal composability [Can01], commitments cannot be implemented without additional assumptions such as that of a publicly available common reference string [CF01]. Here, as an alternative to the commitments in the common reference string model, the use of random oracles to achieve universal composability of commitment protocols is motivated. Special emphasis is put on the s...
