Novel second-order multifunction filters operating in current mode are described. Their structure is based on three current operational amplifiers connected in a feedback loop. These active elements are dual to the well-known operational amplifiers and are suitable for high-frequency signal processing. The designed filters offer low-pass, band-pass and high-pass transfer functions simultaneousl...

We prove the existence of strong solutions to a nonlinear evolution equation of the form  u′(t) + g(t) = f(t) + h(t) g ∈ SL2{∂φ(u(·))} f ∈ SL2{F (·, u(·))} u(0) = −u(T ), in a Hilbert space H, where φ : D(∂φ) ⊂ H → IR+ is a proper, convex, l.s.c. function of compact type, F : [ 0, T ]×D(∂φ)→ 2 is a multifunction which is demiclosed and dominated in some sense by ∂φ and h ∈ L(0, T ;H) is suf...

A PC-based system to control the stimulation, data acquisition, and analysis of evoked field potentials from the dentate subfield of the hippocampal formation in the behaving adult rat is presented. The system consists of a commercially available stimulation generator, multifunction I/O board (16 bit), graphical programming language (LabVIEW), and customized virtual instruments (VI's). System o...

In this study, six grounded inductance simulator circuits are presented including additional useful features in comparison to previous dual-X current conveyor (DXCCII) based implementations. To demonstrate the performance and usefulness of the presented circuits, one of them is used to construct a fifth order Butterworth highpass filter and a current-mode multifunction filter as application exa...

Using a construction similar to an iterated function system, but with functions changing at each step of iteration, we provide a natural example of a continuous one-parameter family of holomorphic functions of infinitely many variables. This family is parametrized by the compact space of positive integer sequences of prescribed growth and hence it can also be viewed as a parametric description ...

For a Banach space X we demonstrate the equivalence of following two properties: (1) is B-convex (that is, possesses nontrivial infratype), and (2) if F:[0,1]→2X∖{∅} multifunction with bounded values, convF denotes t↦conv(F(t)), then Riemann integrability equivalent to F. multifunctions relatively norm compact values F without any restrictions on X.

This article presents two new, reconfigurable multifunction floating-gate circuit to produce either the INVERTED CARRY function for a FULL-ADDER, an INVERTER, or two-input NAND or NOR gates. The circuits contains two MOSFETs and three or four capacitively coupled input signals. SPICE simulations are shown, demonstrating the principal operation, together with preliminary measurements indicating ...

A multifunction printer enables the printing of time-based media. Based on received time-based media data, the printer produces a paper or other printed output as well as a related electronic output. Together, the printed and electronic outputs provide a representation of the time-based media. Depending on the desired application for the printer, the printer may include any combination of mecha...

In the general aviation (GA) community, an automated aircraft is generally comprised of an integrated advanced avionics system consisting of a primary flight display (PFD), a multifunction display (MFD) including an instrumentcertified global positioning system (GPS) with traffic and terrain graphics, and a fully integrated autopilot. This type of aircraft is commonly known as an advanced avion...

This paper sheds new light on regularity of multifunctions through various characterizations of directional Hölder/Lipschitz metric regularity, which are based on the concepts of slope and coderivative. By using these characterizations, we show that directional Hölder/Lipschitz metric regularity is stable, when the multifunction under consideration is perturbed suitably. Applications of directi...
