This paper is devoted to trajectory tracking control for port-Hamiltonian systems. The control law presented here is extension of an existing passive velocity field controller for fully actuated mechanical systems. The proposed method employs vector fields on the phase (co-tangent) spaces instead of those on the velocity (tangent) spaces. Since port-Hamiltonian systems can describe a wider clas...

We consider several approaches for reducing the complexity and power dissipation in processors that use separate register file to maintain the commited register values. The first approach relies on a distributed implementation of the Reorder Buffer (ROB) that spreads the centralized ROB structure across the function units (FUs), with each distributed component sized to match the FU workload and...

The study presents three-port reflecting cell model for analyzing SAW structures employing strong electrode reflections. Basic objective is to analytically approximate all the p-matrix elements for a SAW structure in terms of reflection, transduction, and transmission strengths. This model is an approximate one and it does not take into account the effects of bulk wave excitation, diffraction, ...

A simple algorithm is presented for evaluating scattering parameters of a two-port network. This technique uses the indefinite admittance matrix to calculate scattering or any other desired set of two-port parameters.

Marine economic cooperation has emerged as a major theme in this era of globalization; hence, maritime network connectivity and dynamics have attracted more and more attention. Port construction and maritime route improvements increase maritime trade and thus facilitate economic viability and resource sustainability. This paper reveals the regional dimension of inter-port linkage dynamic struct...

The basolateral amygdala complex (BLA) has been identified as a critical structure mediating fear extinction. However, little is known about the functional role of neurons in the BLA during the extinction of a reward-seeking behavior. Here, we used in vivo electrophysiology procedures in freely moving rats to investigate whether and how the BLA encodes the extinction of responding for sucrose. ...

A new design of dual-port monopole-slot-like microstrip active integrated antenna (AIA) is presented and discussed in this paper. The primary designed passive antenna is capable of supporting two different WLAN bands at 2.4–2.84 GHz and 5.15–5.35 GHz due to its dual-port structure. In order to reduce the transmission coefficient between the two ports of antenna a coupling sleeve-arm and an inve...

UPPAAL PORT is a new tool for component-based design and analysis of embedded systems. It operates on the hierarchically structured continuous time component modeling language SaveCCM and provides efficient model-checking by using partial-order reduction techniques that exploits the structure and the component behavior of the model. UPPAAL PORT is implemented as an extension of the verification...

The frameworks of thermodynamic availability function and irreversible port Hamiltonian systems are used to derive passivity based control strategies for irreversible thermodynamic systems. An energy based availability function is defined using as generating function the internal energy. This is a variation with respect to previous works where the total entropy usually corresponds to the genera...

A clutter or antichain on a set defines a hypergraph. Matroid ports are a special class of clutters, and this paper deals with the diameter of matroid ports, that is, the diameter of the corresponding hypergraphs. Specifically, we prove that the diameter of every matroid port is at most 2. The main interest of our result is its application to secret sharing. Brickell and Davenport proved in 198...
