Information provision and monitoring of the decision-maker in the presence of an appeal process
No full textWe consider a setting where a decision-maker has to resolve a dispute between
two parties. On demand of the losing party, the decision may be subject to review
by an appellate body. The decision-maker has discretionary power and may be
opportunistic. Depending on the institution design, information on the dispute is
provided either by the parties themselves or by an independent investigator. We
show that information provision by the parties generates more efficient monitoring
through appeals and less opportunism by the decision-maker than information
provision by the investigator. We discuss our results in light of the adversarialversus-
inquisitorial controversy
CML and ECL: Optimized Design and Comparison
No full textIn this paper a pencil and paper optimized design for CML and ECL gates is proposed. The approaches are based on simple models which show errors lower than 20% compared with Spice simulations.
The optimization is performed in terms of bias currents which give the minimum propagation delay, and it is demonstrated that at the cost of a 10% increase in propagation delay we can reduce the power dissipation by 40%. Strategies to optimize the transistor area of the CML gates are also discussed.
A comparison between the optimized CML and ECL is made. It shows the advantage of the CML gate with respect to the ECL in terms of propagation delay. However, this feature of CML is paid for in terms of power dissipation.
The simple models used and the design strategies are validated by using both a traditional and a high-speed bipolar process which have a transition frequency equal to 6 GHz and 20 GHz, respectively
Performance Evaluation of Adiabatic Gates
No full textIn the paper the buffer and the NAND/NOR adiabatic gate are compared with that designed with the traditional CMOS approach. The comparison is made both assuming an assigned power supply and setting its value to minimize the power consumption. General relationship independent from process parameter, which are also simple to be useful in a pencil-and-paper evaluation, are carried out.
Analytical results are validate with Spice Simulations by using 0.8-m CMOS technology. The analysis show that with the considered technology and a fan-out of three, the adiabatic buffer is advantageous for frequency lower than 167 MHz and 21 MHz for the non optimized and the optimized design, respectively. These frequencies lower to 23 MHz and 1.3 MHz for the NAND/NOR gate. Moreover all the frequency reduce linearly increasing the fan out of the gate

Numerical modelling of the annealing determined by short-term laser treatment using a physical simulation-based approach
No full textThe local modification of the material properties, especially in the case of Aluminium alloys, is considered a promising solution to overcome the poor formability at room temperature. According to this approach, the Aluminium blank is preliminary subjected to a short-term local heat treatment (usually by laser heating) and then, once cooled down to room temperature, subjected to the forming operations. The present work proposes a numerical methodology to predict the effect of a laser heating, locally bringing a AA5754-H32 blank to the fully annealed state. The Gleeble 3180 physical simulator was used to reproduce the annealing laser treatment by heating AA5754-H32 striped samples under different conditions of time and tempera-ture: specimens, once cooled down to room temperature, were then subjected to hardness measurement and the resulting data used to calibrate a sigmoid function describing the level of annealing according to the time and the maximum temperature reached during the heat treatment. The logistic function was then implemented in a python script able to post-process the results from a thermal transient simulation and, by extracting the temperature history from each node, predict the final distribution of properties. The methodology is then validated by comparing the predicted distribution of properties and the measured one on AA5754-H32 samples subjected to different laser heating strategies. & COPY; 2023 CIRP
New and renewed perspectives on translation: a selected bibliography of Translation Studies (1997-2007)
No full textThe aim of this selected bibliography, therefore, became primarily that of providing a picture of some new directions emerging in the field of Translation Studies in the last ten years or so. We also looked, however, at some traditional areas that in the same years received new impulse by advances in research, Machine Translation being a fitting example. In selecting the titles, we have by no means aimed at being exhaustive; in describing a field such as Translation Studies at the beginning of the new millennium, exhaustiveness has probably become an unattainable ideal, such is the number of titles published each year and the proliferation of different perspectives and angles from which translation is observed and researched. The idea behind this bibliography was, rather, to indicate a few titles that can be associated with either the emergence or the consolidation of new directions in research. In selecting the titles, then, quite a few recent, important works have been left out, especially among those that build on approaches that had already firmly established themselves in earlier periods than the one we are considering. A case in point here would be works reporting on research in empirical studies (especially process-oriented studies), currently a dynamic area of research whose consolidation, however, can be traced back to the period immediately following the publication of Wolfgang Lörscher and Hans P. Krings’s works in the 1980s

No full textVery Fast Carry Energy Efficient Computation based on Mixed Dynamic/Transmission-Gate Full Adders
No full textA circuit approach based on the adoption of mixed dynamic and transmission-gate Full Adder topologies to achieve very fast computation in carry chains is discussed. From a design point of view, the approach is very simple and permits to exceed the speed performance of fast domino logic by more than 30% without degrading the energy efficiency. Post-layout simulations on a 90-nm CMOS technology are presented to validate the results
