This special issue of The European Journal of Control is dedicated to some of the results of the European Community Esprit LTR Project VHS Veri cation of Hybrid Systems It consists of papers dealing with various aspects of one of the case studies treated in the project the Experimental Batch Plant at the university of Dortmund Before presenting the papers themselves it is worthwhile to say some...

This paper is dealing with the robust stability of an uncertain three dimensional (3-D) system using existence MATLAB convex hull functions. Hence, the uncertain model of plant will be simulated by INTLAB Toolbox; furthermore, the root loci of the characteristic polynomials of the convex hull are obtained to judge whether the uncertain system is stable or not. A design third order example for u...

Long distance reflexives (LDRs) constitute an interesting phenomenon for theoretical linguistics because they pose a challenge to the standard theory of anaphor binding as put forth in Chomsky (1981) and subsequent revisions of it within the Principles-and-Parameters framework. The standard theory takes a reflexive pronoun to be an anaphor subject to the condition in (1) (henceforth, BCA), with...

We discuss the tuning of the anisotropic clover action and Symanzik-improved gauge action in lattice perturbation theory. The fermion action is constructed from stout-smeared spatial links, which complicates the calculation considerably. In addition, the full quark-mass dependence of the action parameters is included in this study. We present results for the fermion and gauge aspect ratios for ...

This paper describes an efficient model for twistedpair cables suitable for discrete time simulations. The model uses a pole-zero approximation for the cable losses, and a modified s-parameter approach to model the reflections due to discontinuities and stubs. Use of this model can improve simulation times by a factor of ten compared to using the conventional method of including the channel imp...

Digital waveguides are generalized to the multivariable case with the goal of maximizing generality while retaining robust numerical properties and simplicity of realization. Multivariable complex power is defined, and conditions for “medium passivity” are presented. Multivariable complex wave impedances, such as those deriving from multivariable lossy waveguides, are used to construct scatteri...

Medicating drinking water with tetracycline is commonly used in swine production systems to treat and prevent disease outbreaks. However, little information is known of the pharmacokinetics of this medication in water formulations. Twenty-four barrows, divided into 1 control group (of nontreated animals) and 3 equally sized treatments groups (n = 6/group), were treated with tetracycline water m...

In the present paper, a computer-aided approach to fault observability investigation of linear analog circuits is developed. The method is based on sensitivity investigation of the test characteristics in the frequency domain. The test frequencies are selected maximizing the sensitivity of the magnitude of the test characteristics. Applying postprocessing of the simulation results using macrode...

This paper discusses modelling two 6 DOF arm robots. The first step of modelling a robot is establishing its Denavit-Hartenberg parameters. It requires assigning proper coordinates for each link and finding their exact dimensions. In this project we will develop the direct kinematics and workspace representations for two manipulators: the Smokie Robot and the Barrett WAM. After finding the D-H ...
