Popular Abstract in Swedish Den s.k. "uncertain dichotomous choice" modellen används för att beskriva gruppbeslut. Modellen består av två komponenter: gruppstruktur och röstsystem. Gruppen utgörs av ett antal personer med ett gemensamt mål. Medlemmarnas uppgift är att välja ett av de två givna alternativen, av vilka det ena är korrekt. Dessa två symmetriska alternativ antas så utformade att det inA probabilistic framework used in studying collective decision making is the uncertain dichotomous choice model. The model is essentially characterized by two components: the organizational structure and the voting process. By organizational structure, we refer to a group composed of members with common objectives and who are tasked to choose one of the two given alternatives, one of which is assu

We study the statistical theory of shape for ordered finite point configurations, or otherwise stated, the uncertainty of geometric invariants. Such studies have been made for affine invariants, where a bound on errors is used instead of errors described by density functions, and a first-order approximation gives an ellipsis as uncertainty region. Here, a general approach for defining shape and fi

We present an approach and examples of design artefacts from on-going work on how children with profound disa-bilities can participate in formative design processes. It involves the pedagogical use of digitally interactive mul-tisensory environments. Rather than mimic participatory design from more symmetrical contexts, we address po-tentials in the situation at hand as well as the key issues of v

The 16O(gamma,pn) reaction has been measured with a resolution high enough to resolve individual low-lying states in the residual 14N nucleus. The relative population of the states provides detailed information about the quantum numbers of the proton-neutron pairs on which photons are absorbed. Partial cross-sections, available to the acceptance of the detector system, have been extracted for the

Prepared under the framework of the European Cluster Alliance (ECA), the report provides an overview of existing good practice examples of different tools and analytical methods used during the cluster-making process. The report is based on the results of an international survey of experts working in the field, and the outcomes of a workshop organised in Copenhagen in September 2008. A number of

The linear $H^infty$ control problem is stated for time-varying plant with arbitrary delays and discontinuous coefficients. The image representation of the plant is explicitly written and full solution to the suboptimal control problem is presented. Necessary and sufficient conditions for existence of a solution are derived from the abstract principle of maximum. No Riccati equations are used. The

The Large Hadron Collider (LHC) will be ready for proton-proton collisions in the year 2005 and the ATLAS detector will be one of the two experiments at the LHC which will explore a new and higher energy range for particle physics. In this thesis, an analysis of the power of the ATLAS detector to detect a Standard Model Higgs boson has been performed. It is shown that it will be possible to discov

The paper presents how object-oriented sequential function charts can be used to implement a batch control recipe management system. Grafchart, a toolbox based on Grafcet, object-oriented programming ideas and High-level Petri nets, is presented. It is shown how the concepts of Grafchart fit the models defined in the ISA batch control standard ISA-S88.01. A simulated batch process cell scenario is

Numerous geometric problems in computer vision in- volve the solution of systems of polynomial equations. This is true for problems with minimal information, but also for finding stationary points for overdetermined problems. The state-of-the-art is based on the use of numerical linear algebra on the large but sparse co- efficient matrix that represents the expanded original equation set. In this
