identifying Library functions in executable File using patterns
Australian Software Engineering Conference, 1998Co-Authors: M Van EmmerikAbstract:Re-engineering from legacy executable (binary) Files is greatly facilitated by identifying and naming statically linked Library functions. This paper presents an efficient method for generating Files of patterns; each pattern is a transformation of the first several bytes of a Library function's executable code. Given a suitable pattern File, a candidate function can be identified in linear time. One pattern File is generated for each combination of compiler vendor, version and memory model (where applicable). The process of identifying these parameters in a given executable File also identifies the main function of the program, i.e. the start of the code written by the user. The pattern Files are produced automatically from a compiler's Library File in a few seconds, with no user intervention required. Due to various limitations, not all Library functions can be identified correctly; a small number will be either incorrectly identified or not identified. Optimal perfect hash functions are used to keep the pattern Files compact and efficient to process.

jpcalc a software package for calculating liquid junction potential corrections in patch clamp intracellular epithelial and bilayer measurements and for correcting junction potential measurements
Journal of Neuroscience Methods, 1994Co-Authors: Peter H. BarryAbstract:Abstract The JPCalc program has been designed to graphically illustrate how junction potential contributions arise in various electrophysiological situations, to enable the magnitude and direction of those values to be readily calculated and to show clearly how the resultant appropriate corrections need to be applied to experimental measurements. In particular, the program covers the analysis of junction potential contributions and corrections in all the various different patch-clamp configurations (intact patches, inside-out patches, outside-out patches, whole-cell recording and perforated patches), intracellular recording, epithelial and bilayer measurements. It can also be used to correct experimental measurements designed to try to directly measure junction potentials and to compare both the magnitude and direction of such corrected measurements with their theoretical values. Although it is recommended that all of the above measurements be done with salt-filled electrodes or salt bridges, the program will allow the use of Ag/AgCl reference electrodes in direct contact with bathing solution in most situations. JPCalc also makes use of a Library File of mobility and valency data for about 30 ions which can be extended by the user. In addition to its value in correcting electrical measurements, the program with its graphical displays may also be of value in focusing discussion about the contribution of junction potentials to such measurements and in helping to design experiments to either minimize their contribution or to measure their values. The JPCalc program, designed for IBM-compatible computers with color or monochrome monitors, can also be run on Macintosh computers with SoftPC emulation software. 1

ANITA-2000 activation code package - updating of the decay data libraries and validation on the experimental data of the 14 MeV Frascati Neutron Generator
EPJ Web of Conferences, 2016Co-Authors: Manuela FrisoniAbstract:ANITA-2000 is a code package for the activation characterization of materials exposed to neutron irradiation released by ENEA to OECD-NEADB and ORNL-RSICC. The main component of the package is the activation code ANITA-4M that computes the radioactive inventory of a material exposed to neutron irradiation. The code requires the decay data Library (File fl1) containing the quantities describing the decay properties of the unstable nuclides and the Library (File fl2) containing the gamma ray spectra emitted by the radioactive nuclei. The fl1 and fl2 Files of the ANITA-2000 code package, originally based on the evaluated nuclear data Library FENDL/D-2.0, were recently updated on the basis of the JEFF-3.1.1 Radioactive Decay Data Library. This paper presents the results of the validation of the new fl1 decay data Library through the comparison of the ANITA-4M calculated values with the measured electron and photon decay heats and activities of fusion material samples irradiated at the 14 MeV Frascati Neutron Generator (FNG) of the NEA-Frascati Research Centre. Twelve material samples were considered, namely: Mo, Cu, Hf, Mg, Ni, Cd, Sn, Re, Ti, W, Ag and Al. The ratios between calculated and experimental values (C/E) are shown and discussed in this paper.

updating of the libraries included in the anita 2000 code package on the basis of the jeff 3 1 1 radioactive decay data Library
2014Co-Authors: Manuela FrisoniAbstract:Sommario ANITA-2000 is a code package for the activation characterization of materials exposed to neutro n irradiation released by ENEA at OECD-NEADB (NEA-1638). The package contains: a) the activation code ANITA-4M, based on the originaI code developed at CEC JRC Ispra, able to compute the radioactive inventory of a material exposed to neutro n irradiation, continuous or stepwise, b) two activation cross section libraries, c) the decay data Library (File "fll") containing the quantities describing the decay properties of unstable nuclides and d) the Library (File "fl2") containing the gamma ray spectra emitted by the radioactive nuclei in the ORNL-SCALE I8-y energy group structure. The data contained in the "fll" and "fl2" libraries of the ANIT A-2000 code package are based on the evaluated data Library FENDLlD-2.0. Taking into account a specific interest of ENEA and Ansaldo Nucleare, the ANITA-2000 "fll" and "fl2" libraries were updated on the basis ofthe JEFF-3. 1.l Radioactive Decay Data Library. This work required the setting up ofa series of proper interface codes in order to process and convert the JEFF-3.l.I evaluated decay data (in ENDF-6 standard format) into the format required by ANITA-4M code. A preliminary validation of the new libraries has been performed through the comparison of the ANIT A-4M calculations against measurements of electron-photon decay heat and activity of neutron activated materials from FNG (Frascati Neutron Generator) experiment.
