    The Unconstitutionality of Consolidated Planning Boards: Interlocal Planning Under New York Law

    This Article will examine the nature and constitutionality of consolidated planning boards in light of the broad powers actually granted them. The issues surrounding the constitutionality of consolidated planning boards begs, yet again, Chief Justice Marshall\u27s question respecting the extent of the power granted to the state governments. The question is whether a municipality may abdicate its power to regulate land within its own boundaries by delegating it to a separate planning entity

    CdWO4 scintillating bolometer for Double Beta Decay: Light and Heat anticorrelation, light yield and quenching factors

    Full text link
    We report the performances of a 0.51 kg CdWO4 scintillating bolometer to be used for future Double Beta Decay Experiments. The simultaneous read-out of the heat and the scintillation light allows to discriminate between different interacting particles aiming at the disentanglement and the reduction of background contribution, key issue for next generation experiments. We will describe the observed anticorrelation between the heat and the light signal and we will show how this feature can be used in order to increase the energy resolution of the bolometer over the entire energy spectrum, improving up to a factor 2.6 on the 2615 keV line of 208Tl. The detector was tested in a 433 h background measurement that permitted to estimate extremely low internal trace contaminations of 232Th and 238U. The light yield of gamma/beta, alpha and neutrons is presented. Furthermore we developed a method in order to correctly evaluate the absolute thermal quenching factor of alpha particles in scintillating bolometers.Comment: 8 pages 7 figure

    The rise of Jobbik poses a credible threat to Fidesz’s dominance in Hungary

    Get PDF
    Fidesz has been the dominant party in Hungary in recent years and secured a ‘supermajority’ of two-thirds of MPs in the Hungarian parliamentary elections in 2014. However, as Andrea L. P. Pirro writes, the party’s position has come under threat of late, with a by-election loss earlier in the year removing the supermajority, while another by-election on 12 April was won by a representative from the far-right Jobbik party. He argues that while the era of Fidesz dominance is far from over, the rise of Jobbik poses a challenge for the country’s Prime Minister, Viktor Orbán

    Performances of the Italian seismic network, 1985-2002: the hidden thing

    Full text link
    Seismic data users and people managing a sesimic network are both interested in the potentiality of the data, with the difference that the former look at stability, the second at improvements. In this work we measure the performances of the Italian Telemetered Seismic Network in 1985-2002 by defining basic significant parameters and studying their evolution during the years. Then, we deal with the geological methods used to characterise or to plan a seismic station deployment in a few cases. Last, we define the gain of the network as the percentage of located earthquakes with respect to the total recorded earthquakes. By analysing the distribution of non-located ("missed") earthquakes, we suggest possible actions to take in order to increase the gain. Results show that completeness magnitude is 2.4 in the average over the analysed period, and it can be as low as 2.2 when we consider non-located earthquakes as well. Parameters such as the distance between an earthquake and the closest station, and the RMS location decrease with time, reflecting improvements in the location quality. Methods for geologic and seismological characterisation of a possible station site also proved to be effective. Finally, we represent the number of missed earthquakes at each station, showing that nine stations control more that 50% of all missed earthquakes, and suggesting areas in Italy where the network might be easily improved.Comment: 17 pages, 1 table, 11 figures.

    Global Tracking Passivity--based PI Control of Bilinear Systems and its Application to the Boost and Modular Multilevel Converters

    Full text link
    This paper deals with the problem of trajectory tracking of a class of bilinear systems with time--varying measurable disturbance. A set of matrices {A,B_i} has been identified, via a linear matrix inequality, for which it is possible to ensure global tracking of (admissible, differentiable) trajectories with a simple linear time--varying PI controller. Instrumental to establish the result is the construction of an output signal with respect to which the incremental model is passive. The result is applied to the boost and the modular multilevel converter for which experimental results are given.Comment: 9 pages, 10 figure
