Le Mécénat D'entreprise Face Aux Fusions-acquisitions: Nouveaux Ancrages, Nouvelles Perspectives

In 2001, l'Observatoire de la Générosité et du Mécénat conducted a survey on the impact of mergers and acquisitions on the sponsoring policies of 15 French and international companies. This report describes a second survey which was undertaken in 2003-2004 analysing 10 of the original companies to verify the accuracy of the conclusions from the initial survey

FLC−SIPM: Front-End Chip for SIPM Readout for ILC Analog HCAL

eConf: C050318 : LCWS-2005-0916An integrated front-end chip has been developed to readout the Silicon PM for the ILC analog hadronic calorimeter. It is built around a variable gain low-noise preamplifier followed by a variable peaking-time shaper (20-200 ns), track and hold and multiplexed output. This structure allows to produce single photo electron spectrum with well separated peaks for absolute calibration at fast shaping (40ns) as well as physics signals from the scintillating fibbers (up to 2000 photo-electrons) with a slower shaping (150ns) compatible with the W-Si Electromagnetic Calorimeter DAQ. Besides, an input DAC allows to tune the detector gain by varying the operating voltage by up to 5V. The chip accommodates 18 channels and 1000 circuits have been produced in 2004, the design and the measurement results of which will be presented

Dedicated front-end electronics for the next generation of linear collider electromagnetic calorimeter

This paper describes an R&D electronic program for the next generation of linear collider electromagnetic calorimeter. After a brief presentation of the requirements, a global scheme of the electronics is given. Then, we describe the three different building blocks developed in 0.35\mum CMOS technology: an amplifier, a comparator and finally the pipelined AD

Front-end Electronic for the Calice ECAL Physics Prototype

eConf: C050318 : 0902A 18-channel low-noise front-end chip has been designed and produced to read out the 1cm² silicon PIN diodes of the CALICE WSi physics prototype calorimeter. Each channel includes a multi-gain low noise charge preamplifier followed by a bi-gain shaper and a track and hold device. A single output allows reading out every channel at 5 MHz through a multiplexer. Voltage swing is 2.5V with a 5‰ non-linearity. The measured dynamic range on a fixed gain is larger than 13 bits. The gain of the preamplifier can be tuned from 0.3V/pC to 5V/pC with 4 bits. The shaping is done by two fixed-gain shapers (gain 1 and gain 10). Output measured noise is 3000 e- with a detector capacitance of 100pF and a MIP around 42000 e-. Crosstalk is around 1‰. 1000 chips have been produced to equip the physics prototype. Several version of PCB have been designed, taking into account the thickness constraint. A first version with the front-end chip outside the detector has been produced and has been running since January 2005 at DESY, exhibiting an overall MIP/noise ratio of 9. A new thinner version embedding the chip inside the calorimeter has been prototyped and is ready to go in test beam

“ROC” Chips Readout

International audienceThe OMEGA group at LAL has designed 3 chips for ILC calorimeters: one analog (SPIROC) and one digital (HARDROC) for the hadronic one and also one for the electromagnetic one (SKIROC). The readout and the management of these different chips will be explained. To minimize the lines between the ASICs and the DAQ, the readout is made thanks to 2 lines which are common for all the chips: Data and TransmitOn. As the chips are daisy chained, each chip is talking to the DAQ one after the other. When one chip has finished its readout, it starts the readout of the chip just after. Moreover, during this readout, only the chip which is talking to the DAQ is powered: this is made thanks to the POD (Power On Digital) module in the ASIC. In the ILC mode, readout sequence is active during inter bunch crossing (like ADC conversion). Another chip designed for PMM2 R&D program (PARISROC) integrates a new selective readout: that's mean only hit channels are sent to the DAQ in a complete autonomous mode

Moral e Ética:: Uma Leitura Psicológica

After nearly a century of reflections and investigations, as it would be expected, the classical theoretical referentials of Moral Psychology show signs of exhaustion. Consequently, new perspectives open up, including the theoretical approach that takes the name of ‘ethic personality’, whose thesis is: to understand the moral behavior (duties) of individuals, one needs to know the ethical perspective (good life) adopted by them. Among the psychological invariants to hold a ‘good life’ is the need for ‘expansion of the self’. Such expansion involves positive ‘self representations’, among of which may be those related to morality. If so, the subject will experience the feeling of duty, otherwise, the motivation for moral action will be weak or non-existent.Após um século de reflexões e investigações, como era de se esperar, a Psicologia Moral apresenta sinais de esgotamento de seus referenciais teóricos clássicos. Consequentemente, novas perspectivas se abrem, entre elas a abordagem teórica que leva o nome de ‘personalidade ética’, cuja tese é: para compreendermos os comportamentos morais (deveres) dos indivíduos, precisamos conhecer a perspectiva ética (vida boa) adotadas por eles. Entre os invariantes psicológicos de realização de uma ‘vida boa’, está a necessidade de ‘expansão de si próprio’. Como tal expansão implica ter ‘representações de si’ de valor positivo, entre elas poderão estar aquelas relacionadas à moral. Se estiverem, o sujeito experimentará o sentimento de dever, do contrário, a motivação para a ação moral será inexistente ou fraca

L’œuvre de l’architecte Edmond Chambert à Bagnères-de-Luchon (Haute-Garonne)

L’architecte Edmond Chambert (1811-1881) a fortement marqué la ville de Bagnères-de-Luchon dans le troisième quart du XIXe siècle. Il participe à la structuration de la station en y concevant un grand établissement thermal qui conjugue classicisme du parti et modernité de l’organisation. Il répond à de nombreux projets municipaux d’aménagements urbains, parmi lesquels le casino, qui tous n’aboutissent pas. Il est par ailleurs sollicité par les notables de la ville pour leur construire de grandes demeures, vouées à la villégiature des curistes fortunés. C’est au gré de ces commandes que s’observe le mieux le caractère éclectique de son œuvre.Architect Edmond Chambert (1811-1881) strongly influenced the city of Bagnères-de-Luchon during the third quarter of the 19th century. He participated actively in developing the resort, by designing a large spa that combines both classicism, and modern organization. He worked on many municipal urban development projects, including the casino, not all of which were successful. He was also commissioned by city noblemen to build large homes for accommodating wealthy guests during their stay in the spa town. These commissioned residences best display the vivid, eclectic character of his work
