This paper deals with the design of a nonlinear observer for the inverted pendulum. The observer uses the standard structure of the linear observer with the linear model replaced by a nonlinear model. Nominal observer gains are determined from a linearised model. This model is also used to find a compromise between robustness and performance. The stability of the observer is then discussed and con

This paper presents and discusses results from the research project LETS 2050 that studies the governance challenges of a transition to a low-carbon transport and energy system in Sweden by 2050 (www.lets2050.se ). A key starting point of the project was that a low carbon transition is technically possible and economically feasible, while the main challenge is political. At the moment there is an

Nocturnal lepidopteran pollinators face pesticide exposure risks in agricultural landscapes, yet lack adequate risk assessment frameworks compared to diurnal species. We present a formal model description for Noctua pronuba within the Animal Landscape and Man Simulation System (ALMaSS), providing the first comprehensive agent-based framework for assessing the impacts of pesticides on nocturnal mot

Advanced Principles Group (APG) has developed a Reconfigurable Computing Board (RCB) based on the Xilinx Virtex-II Pro FPGA family, potentially capable of 1.5 - 2.0 TeraOps of compute power, 100 Gbps I/O on front panel, 4 Gbps I/O on backplane, as well as containing more than 4 GBytes of on-board memory. Computationally complex applications such as Software-Defined Radio, Synthetic Aperture Radar,

Commentary on Articles 116-119 of the United Nations Convention on the Law of the Sea.

This book is the first in almost 40 years to provide a comprehensive scientific overview of research in the field of parapsychology, explaining what we know and don’t know about so-called psi phenomena, such as “telepathy,” “precognition” or “psychokinesis.” Contributors evaluate the evidence for these phenomena, accounting for factors such as selective memory, wish fulfillment and incorrect metho

A simple model for the gluon structure function at small x is presented, which gives an intuitive picture of the transition between the DGLAP and BFKL regimes

We discuss the point spread function for the Spectro instrument based on realistic effects of the time delayed integration, transverse image motion and pixelization, but assuming rather small wave front errors. Stars brighter than 10 mag, which will saturate the CCD, may be observed photometrically using the image wings, but the central wavelengths will be slightly shifted towards the red.
