A proposito di Harrison
No full textEsistono davvero le “persone”? E cosa dire del “linguaggio”, del “discorso” o della “cultura”? Fino a che punto le reti sociali hanno determinato la specie umana in quelli che consideriamo come i suoi tratti costitutivi? Cosa unisce matematica e sociologia? Domande tanto ambiziose e originali trovano risposte altrettanto innovative in questo volume, in cui si propone la traduzione italiana di due saggi di uno degli ultimi maestri della sociologia americana. Muovendosi con eleganza tra ambiti concettuali e metodologici differenti, Harrison C. White analizza i fondamenti logici ed epistemologici di un approccio attualmente tanto utilizzato quanto raramente compreso in profondità: la social network analysis. I numerosi neologismi appositamente coniati – “forchette bayesiane”, “commutazioni”, “netdom”, “nodi del futuro”, “soluzioni d’angolo” – vengono inquadrati e presentati dai curatori attraverso una guida introduttiva alla lettura

Fluidic packaging of microengine and microrocket devices for high pressure and high temperature operation
No full textThe fluidic packaging of Power MEMS devices such as the MIT microengine and microrocket requires the fabrication of hermetic seals capable of withstanding temperature in the range 20-600/spl deg/C and pressures in the range 100-300 atm. We describe an approach to such packaging by attaching Kovar metal tubes to a silicon device using glass seal technology. Failure due to fracture of the seals is a significant reliability concern in the baseline process: microscopy revealed a large number of voids in the glass, pre-cracks in the glass and silicon, and poor wetting of the glass to silicon. The effects of various processing and materials parameters on these phenomena were examined. A robust procedure, based on the use of metal-coated silicon substrates, was developed to ensure good wetting. The bending strength of single-tube specimens was determined at several temperatures. The dominant failure mode changed from fracture at room temperature to yielding of the glass and Kovar at 600/spl deg/C. The strength in tension at room temperature was analyzed using Weibull statistics; these results indicate a probability of survival of 0.99 at an operational pressure of 125 atm at room temperature for single tubes and a corresponding probability of 0.9 for a packaged device with 11 joints. The residual stresses were analyzed using the method of finite elements and recommendations for the improvement of packaging reliability are suggested

Measurement of the ratio of prompt χ c to J / ψ production in pp collisions at √s = 7 TeV
No full textThe prompt production of charmonium χ c and J / ψ states is studied in proton-proton collisions at a centre-of-mass energy of √s = 7 TeV at the Large Hadron Collider. The χ c and J / ψ mesons are identified through their decays χ c → J / ψ γ and J / ψ → μ + μ - using 36 pb - 1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for χ c and J / ψ, σ (χ c → J / ψ γ) / σ (J / ψ), is determined as a function of the J / ψ transverse momentum in the range 2 < p T J / ψ < 15 GeV / c. The results are in excellent agreement with next-to-leading order non-relativistic expectations and show a significant discrepancy compared with the colour singlet model prediction at leading order, especially in the low p T J / ψ region
