Probing finite size effects in (λΦ4)4(\lambda \Phi^4)_4 MonteCarlo calculations

The Constrained Effective Potential (CEP) is known to be equivalent to the usual Effective Potential (EP) in the infinite volume limit. We have carried out MonteCarlo calculations based on the two different definitions to get informations on finite size effects. We also compared these calculations with those based on an Improved CEP (ICEP) which takes into account the finite size of the lattice. It turns out that ICEP actually reduces the finite size effects which are more visible near the vanishing of the external source.Comment: LATTICE98(Gauge, Higgs and Yukawa Models

Mass Determination from Constraint Effective Potential

The Constraint Effective Potential (CEP) allows a determination of the mass and other quantities directly, without relying upon asymptotic correlator decays. We report and discuss the results of some mass calculations in $(\lambda \Phi^4)_4$, obtained from CEP and our improved version of CEP (ICEP).Comment: LATTICE99(Higgs, Yukawa, SUSY

Protection of the Environment in Times of Armed Conflict: Reflections on the Existing and Future Treaty Law

This survey indicates that no treaty has been concluded to deal with environmental issues comprehensively. No treaty states basic principles which States would be called upon to observe with respect to the various environmental problems. However, some efforts in this direction are now underway as noted in the concluding section of this paper. The conclusion discusses the current drafts of such general principles as rights and obligations of States in the field of the environment, including specific reference to the question of the environment and armed conflict

Progettazione grafica della mostra didattico-divulgativa CEP50 sulla storia delle macchine per il calcolo prima della CEP (Calcolatrice Elettronica Pisana)

Available in ItalianIl presente lavoro prende in considerazione le fasi di progettazione grafica dei pannelli della mostra CEP50 sulla storia delle macchine per il calcolo prima della CEP (Calcolatrice Elettronica Pisana) e le scelte stilistiche adottate. Vengono presentati tutti i pannelli sia quelli riguardanti la storia, la tecnologia e la ricostruzione della Macchina Ridotta (MR), sia quelli relativi alle ricadute istituzionali dopo la costruzione della MR e della CEP, sui corsi di laurea, e sui progetti di ricerca e industriali correlati. In totale sono stati realizzati 19 pannelli esposti al Museo degli Strumenti per il Calcolo dal 13 novembre 2011, giorno della sua inaugurazione
