Let K be a convex cone in a real Banach space. The main purpose of this paper is to show that for a regular cosine family {Ft : t ∈ R} of linear continuous multifunctions Ft : K → cc(X) there exists a linear continuous multifunction H : K → cc(K) such that Ft(x) ⊂ ∞ X n=0 t (2n)! H(x). Let X be a real normed vector space. We will denote by n(X) the family of all nonempty subsets of X and by cc(...

In this paper we report new results on the regularity of optimal controls for dynamic optimization problems with functional inequality state constraints, a convex time-dependent control constraint and a coercive cost function. Recently it has been shown that the linear independence condition on active state constraints, present in the earlier literature, can be replaced by a less restrictive, p...

The specifications analysis for an MVB (Multifunction Vehicle Bus) bus administrator showed that system-on-a-chip strategies should be adopted to cope with its great complexity. Particularly, a new hardware/software codesign methodology has been followed. Its main concept is that the MVB devices (the bus administrator itself and the less complex devices) constitute a “progressive family”. This ...

Myoelectric systems have received widespread use as controls of prosthetic devices for individuals with amputations or congenitally deficient upper limbs, (Parker and Scott, 1988). Many systems are now available commercially to control a single device (hand, elbow, wrist). These systems extract a control signal based on an estimate of the amplitude, (Dorcas and Scott, 1966), or on the rate of c...

We present a novel multifunction inverse biquad configuration based on current feedback operational amplifiers (CFOAs) and grounded passive elements. The proposed scheme can be used to realize inverse lowpass, inverse bandpass and inverse highpass filter functions. The relevant coefficients of the inverse filters are orthogonal adjustable by independent passive elements. All the passive element...
