    No full text
    Il saggio, concepito come contributo a un volume di studi sulle interpretazioni italiane di Spinoza, è dedicato a Piero Martinetti. L''attenzione si concentra sulla interpretazione martinettiana del problema dei modi finiti e infiniti nell''Ethica e nel Trattato sulla emendazione dell''intelletto

    Robotic manipulation experiments through visual feedback

    No full text
    This paper presents an experimental study on the use of visual servoing for dexterous robotic manipulation. In the first step of the work, a mathematical model of the whole system has been derived, then a non – linear PID regulator with Smith predictorstructure has been developed. The feedback signal for the controller comes directly from the visual sensor. Some experiments on following with robot end-effector a moving target have been performed, showing efficiency of the control system.This work on visual feedback differs from other similar experiments mainly because the inner architecture of the robotcontroller is assumed unknown, i.e. the inner control loop of the robot has not been modified

    MeSH term explosion and author rank improve expert recommendations

    Information overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank

    Going Beyond Counting First Authors in Author Co-citation Analysis

    No full text
    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    "Closing the R&D Gap, Evaluating the Sources of R&D Spending"

    No full text
    Both spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
