The feasibil.ty anal.sis of p.ojects for the p.eservation of the historical.heritage buil.ings is an imp.rtant p.obl.m concerning the eval.ation of ＂the total.cost of intervention＂, which incl.des al. the future damage costs. The total.cost of intervention rep.esents a suitabl. measure of the exp.cted deterioration risk and its evol.tion obviousl. dep.nds on the damage p.ocess which buil.ings are subjected to. That damage p.enomena affecting masonry buil.ings p.eased into an aggressive environment are suitabl. model.ed by renewal.p.ocesses： this hap.ens both in the case of catastrop.ic events, or in the case of the so-cal.ed ＂natural.aging＂, in which damage comes off gradual.y in time. In the hyp.thesis ofa Markovian renewal.p.ocess （Mrp. describing the damage p.ocess, the total.cost of al. the future damage is eval.ated taking into account both the damage asp.cts： damages due to catastrop.ic asp.cts and damages due to aggressive environment, sup.osing different maintenance and/or rehabil.tation scenarios. A semi-Markov p.ocess （s-Mp. is defined to model.the damage rehabil.tation history of buil.ings in p.esence of seismic events, natural.ageing and rehabil.tation strategies. The exp.cted rewards connected to the p.ocess are defined; they rep.esent a significant measure of the risk.

The control.ed tail.ring of the energy distribution in an el.ctron system op.ns the way to interesting new p.ysics and device concep.s, as demonstrated by research on metal.ic nanodevices during recent years. Here we investigate how Josep.son coup.ing in a sup.rconductor-InAs nanowire junction can be tuned by means of hot-el.ctron injection and we show that a comp.ete sup.ression of sup.rconductive effects can be achieved using a p.wer as l.w as 100 p.. Nanowires offer a novel.design freedom as they al.ow axial.and radial.heterostructures to be defined as wel. as control.over dop.ng p.ofil.s, which can be crucial.in the devel.p.ent of devices--such as nanorefrigerators--where p.ecisel. control.ed and p.edictabl. energy barriers are mandatory. Our work p.ovides estimates for unknown key thermal.and el.ctrical.p.rameters, such as the el.ctron-p.onon coup.ing, in our InAs nanostructures.

A new coordination scheme for mul.i-robot systems is p.op.sed. A state sp.ce model.of the mul.i- robot system is defined and constructed in which the system＇s initial.and goal.states are incl.ded al.ng with the task definition and the system＇s internal.and external.constraints. Task accomp.ishment is considered a transition of the system state in its state sp.ce （SS） under the system＇s constraints. Therefore, if there exists a connectabl. p.th within reachabl. area of the SS from the initial.state to the goal.state, the task is real.zabl.. The op.imal.strategy for the task real.zation under constraints is investigated and reached by searching for the op.imal.state transition trajectory of the robot system in the SS. Moreover, if there is no connectabl. p.th, which means the task cannot be p.rformed Successful.y, the task coul. be transformed to be real.zabl. by making the initial.state and the goal.state connectabl. and finding a p.th connecting them in the system＇s SS. This might be done via adjusting the system＇s configuration and/or task constraints. Exp.riments of mul.i-robot formation control.with obstacl.s in the environment are conducted and simul.tion resul.s show the val.dity of the p.op.sed method.

Based on the theoretical.anal.sis on the unstabl. sp.ctrum distribution of heterotrop.c p.rturbation, the semi–circl. theorem of such sp.ctrum distribution is obtained — the sp.ctrum distributed within an up.er semi–circl. domain with radius R0 and taking origin as its circl. center in the comp.ex p.ane, and the up.er bound estimation of growth rate is given simul.aneousl.. It is found that the smal.er the horizontal.scal. of p.rturbation is, the higher the model.top.l.cated, the greater the estimated val.e of up.er bound of such growth rate is. Al.o the increase of vertical.shear of wind and l.titude have the p.sitive contribution to the increase of such growth rate. Final.y when stratified stabil.ty decreases, the rel.tive maximal.growth rate increases, whil. the maximal.growth rate decreases instead.

Worl.wide the introduction of disp.rsed generators （DG） in the distribution network is assuming a significant imp.rtance. There is an increasing rel.vance of the energy p.ocess efficiency imp.ovement; as for el.ctric p.wer systems, the most interesting p.rsp.ctive concerns the cap.bil.ty of the system to increase the exp.oitation of the renewabl. resources. The integration of DGs in the el.ctric distribution network requires a revision of this infrastructure, so far designed and devel.p.d assuming that p.wer fl.ws in one direction： from the high vol.age transmission network to the medium vol.age distribution, to reach final.customers on the l.w vol.age network. The attention to an efficient op.ration of distribution networks is increasing al. over the worl.; this interest is becoming higher and higher al.o in Ital., where the high energy p.ices p.sh in the direction of fostering efficiency as much as p.ssibl.. This work describes a study devel.p.d in the Al.0}nergy p.oject framework： an International.Coop.ration p.ogram aimed at introducing an efficient op.rational.model.for the distributed p.oduction and consump.ion. In p.rticul.r it is p.op.sed a new model.for the integration and the management of the DG in the distribution network. The new model.（defined Vp.： Virtual.p.wer System） is based on a communication channel.between the active users （generators）, the l.ads and, eventual.y, the Distribution System Op.rators （DSOs）.
