Adaptive techniques such as gain scheduling, automatic tuning and continuous adaptation have been used in industrial single-loop controllers for about ten years. This paper gives a survey of the different adaptive techniques, the underlying process models and control designs. The paper ends with an overview of industrial adaptive single-loop controllers.

We study broadcasting (one-to-all communication) in known topology radio networks modeled by graphs, where the interference range of a node is likely to exceed its transmission range. In this model, if two nodes are connected by a transmission edge they can communicate directly. On the other hand, if two nodes are connected by an interference edge their transmissions disable recipience of one anot

Atmospheric aerosol particles typically consist of inorganic salts and organic material. The inorganic compounds as well as their hygroscopic properties are well defined, but the effect of organic compounds on cloud droplet activation is still poorly characterized. The focus of the present study is the organic compounds that are surface active i.e. tend to concentrate on droplet surface and decrea

This study examines how globalization of corporate governance practices influence the risk of European CEOs being dismissed. We argue that the harsh monitoring of the American corporate governance system spills over to the rest of the world as a result of this globalization. We focus on direct and indirect American influence on the dismissal performance sensitivity among the 250 largest European p

In this paper we present some experiments on the MySQL database server. The objective of the experiments was to investigate the high load dynamics for varying relation sizes and requests. We show that the dynamics for SELECT (read) requests can be modeled as a modified M/M/1 system, whereas, the dynamics for UPDATE (write) are completely different. Our results can be used for designing control and

In 2009 the conservative Swedish government launched a new cultural policy proposition emphasising broader engagement in the arts both consumption-wise, politically and economically. This proposition and two specific elements of it will be discussed in this paper; the cooperation and consultation model of distribution of state support to regional culture and schemes for stimulating broadened, i.e.

A method based on power series expansions of the surface charge density, with Legendre polynomials as basis functions, is introduced in this paper. With a Galerkin method, applied to the method of moment, the resulting integrals for the elements of the impedance matrix are four dimensional. The corresponding integrands are products of the static Green function and Legendre polynomials. The introdu
