A new procedure for constrained pole-placement is presented. The poles of the closed loop system are placed within a circle in the left half plane. The design procedure is noniterative and the solution is obtained via linear quadratic (LQ) design for a transformed system. The circle can be chosen in order to obtain good transient properties of the closed loop system. The method combines the proper

The structure of real and virtual photons has been studied in electron-proton scattering processes producing di-jet events at HERA by the H1 and ZEUS collaborations. Data have been compared to next-to-leading order QCD calculations and to the predictions of Monte Carlo generators based on the DGLAP and CCFM formalisms for describing the parton dynamics.

Popular Abstract in Swedish Utforskar äldre och funktionshindrades behov av planeringsinformation i kollektivtrafiken och diskuterar huruvida information kan bidra till tillgängligheten. En omfattande enkätundersökning genomfördes för att validera tidigare genomförda fokusgruppsintervjuer om äldre och funktionshindrades informationsbehov. Resultaten visar att det finns ett behov av information blaExplores elderly and disabled people's travel information requirements when planning a journey by public transport and discusses the potential of information to improve access to the public transport system. Quesionnaire study in order to validate an earlier focus-group interview study about elderly and disabled people's travel information requirements. Results show a need for travel information t

This work presents the fabrication and characterization of 3 dimensional electrodes from pyrolysed carbon with spacing and diameter approaching the resolution limit of standard UV photolithography. Our carbon pillar arrays have a diameter of 1.4 µm, spacing of 5 µm and aspect ratio of about 8. We show their characterization by a variety of techniques providing a complete summary of their electro-m

This study attempts to discover how ergonomic guidelines should be visualized in order to make it easier and more interesting to find and interpret the guidelines throughout the construction process. A prototype visualizing ergonomic guidelines at the intranet has been developed and evaluated at a company that produces cars for the global market. The results shows that the visualization of ergonom

This study examines the impact of contextual factors on social mediated crisis by revisiting the concept of “modifier” in situational crisis communication theory (SCCT). Existing studies on “modifiers” in SCCT largely limit their scopes within the organizational domain and overlook the impact of contextual factors beyond organization, such as society, politics, and culture. To advance the understa

In this paper, we describe how we use a named entity disambiguation module to merge entities in a question answering system. The question answering system uses a baseline passage retrieval component that extracts paragraphs from the Swedish version of Wikipedia. The passages are indexed and ranked using the Lucene platform. Prior to the indexing, we carried out a recognition and disambiguation of
