Thinking Academic Evaluation after Michèle Lamont’s "How Professors Think"
No full textTHIS IS A SYMPOSIUM, edited by Anna Carola Freschi and Marco Santoro, of the journal "Sociologica" (published by il Mulino). It is about the issue of academic evaluation, and moves from a discussion of a recent book by the American sociologist Michele Lamont, who participates to the Symposium as well. The contributors are from various countries (France, UK, Germany, Italy) and different specialties (sociology of science, cultural sociology, economic sociology etc.
Dual-PEEC Modeling of a Two-Port TEM Cell for VHF Applications
No full textTwo-port TEM cells with rectangular cross section are commonly used to produce plane electromagnetic waves with high electric field. The non-uniform structure makes the use of numerical methods extremely useful in the design phase in order to achieve a very good behavior of the TEM cell over a wide frequency range of operation. In this paper an extended version of PEEC is used to study a real device and results are compared with experimental ones
A Source Identification Problem for the Electrical Activity of Brain During Hand Movement
No full textA field source reconstruction of the dipoles modeling the activated area of the brain, while a subject performs the task of the voluntary motion of the hand, is solved. Experimental data resulting from fMRI are used for constraining the position of the equivalent dipole
Rule-extension-strategies in Ancient India: Ritual, exegetical and linguistic considerations on the tantra- and prasaṅga- principles
No full textThe authors focus their attention on the usage and cultural history of two crucial terms in Sanskrit technical literature, namely tantra and prasaṅga (here translated as ‘centralised joint application’ and ‘automatic involvement’). They belong to a class of devices used to ‘extend’ the validity of a given rule outside its proper domain. Their functioning thus entails an organized spatial dimension which transforms an absolute absence in a specific one. The sources on which this inquiry is based are the most ancient Indian aphoristic treatises on ritual, exegesis and grammar with their first commentaries. A noteworthy outcome of this research is the evidence that a common prehistory and an almost constant mutual influence of these traditions should be postulated for the questioned rules
Use of Finite Formulation of Electromagnetic Field for Solving PEEC Problems on Unstructured Grids
No full textFinite Formulation of Electromagnetic Fields allows to define an algebraic form of Maxwell's equations on an unstructured discretization system. This characteristic is here exploited by defining an equivalent circuit for an unstructured mesh of surface electrodes in an homogeneous dielectric region The constitutive equation of this partial components can be written by means of the electric field integral equation. In this way a generalization of the well known PEEC technique to the case of triangular discretization is obtained. Some results are presented on benchmark cases showing a good agreement with the ones available in the literature
FPGA-Based Parallel Comparison of Run-Length-Encoded Strings
No full textThe length of the longest common subsequence (LCS) between two strings of M and N characters can be computed by O(M×N) dynamic programming algorithms that can execute in O(M + N) on a linear systolic array. If the strings are run-length encoded, LCS can be computed by an O(mN +Mn−mn) algorithm, called RLE-LCS, where m and n are the numbers of runs of the two strings. In this paper we propose a modified RLE-LCS algorithm mappable on a linear systolic array
