Dissensus, death and division

2009

The modeling of switching systems describing networks where death and duplication processes occur is described. A dissensus protocol, complementary to consensus protocol, is introduced and the convergence or divergence of the agents' state evolution is studied. We discuss some properties of the topology reached by the network when different rules of duplication and inheritance are implemented.

In-situ Mössbauer Spectroscopy with MIMOS II at Rio Tinto, Spain

2010

The Rio Tinto, located in southwest Spain, exhibits a nearly constant, acidic pHvalue along its course. Due to the formation of sulfate minerals, Rio Tinto is considered a potential analogue site for sulfate-rich regions on Mars, in particular at the landing site of the Mars Exploration Rover Opportunity, where the ferric sulfate mineral jarosite was identified with Opportunity's Mössbauer spectrometer. Primary and secondary mineralogy was investigated in situ with portable Raman and Mössbauer spectrometers at four different Rio Tinto sampling sites. The two techniques analyse different sample portions due to their specific field of view and sampling depth and provide complementar…

Inclusive Design for Alzheimer’s Disease: Low-cost Treatments, Design and ICT

2019

Inability to acquire new memories, difficulty to remember recent events and to recognize objects, places and people, visual-spatial disorientation, these are some of the disorders with which who is affected by neurological diseases must learn to live with. In a continuously evolving society, where the decreasing birth rate and the drops in mortality are consistent, the job of Architecture is precisely to interpret the requirements and needs of people who have lost the canonical relationship with the world and give them the possibility to recover it or maintain it through communication channels that use their remaining ability to understand. The indoors and outdoors acquire a “prosthesis fun…

Incapacità di acquisire nuovi ricordi difficoltà nel ricordare eventi osservati recentemente mancata identificazione delle cose dei luoghi e delle persone disorientamento visivo-spaziale sono questi e molti altri i disturbi con cui devono imparare a convivere coloro che sono colpiti da malattie neurologiche. In una società in continua evoluzione dove la diminuzione della natalità e l’innalzamento della soglia di mortalità divengono costanti il compito dell’Architettura è proprio quello d’interpretare le esigenze e i bisogni di persone che hanno perso il rapporto canonico con il mondo e offrire loro le possibilità di recuperarlo o di mantenerlo attraverso canali di comunicazione che sfruttino le loro residue capacità di comprensione. Lo spazio interno ed esterno assume così una “funzione protesica” contenendo ed esprimendo in sé le conoscenze necessarie per la sua corretta fruizione riducendo il senso di frustrazione attraverso la sensazione di sicurezza e di benessere che il malato deve percepire vivendolo. Il presente saggio propone un contributo alla diffusione di conoscenze e di informazioni utili a coloro che operano nel settore della programmazione e della progettazione di strutture socio-sanitarie riportando soluzioni terapeutiche “non farmacologiche” low-cost e sostenibili promosse dalla ricerca tecnologica internazionale e nazionale nel settore della progettazione tecnologica e delle ICT e che hanno dimostrato di essere in grado di produrre significativi benefici sia ai malati sia ai caregivers.Settore ICAR/12 - Tecnologia Dell'Architettura

Pricing and hedging GDP-linked bonds in incomplete markets

2018

Abstract We model the super-replication of payoffs linked to a country’s GDP as a stochastic linear program on a discrete time and state-space scenario tree to price GDP-linked bonds. As a byproduct of the model we obtain a hedging portfolio. Using linear programming duality we compute also the risk premium. The model applies to coupon-indexed and principal-indexed bonds, and allows the analysis of bonds with different design parameters (coupon, target GDP growth rate, and maturity). We calibrate for UK and US instruments, and carry out sensitivity analysis of prices and risk premia to the risk factors and bond design parameters. We also compare coupon-indexed and principal-indexed bonds. F…

Estimating feature discriminant power in decision tree classifiers

1995

Feature Selection is an important phase in pattern recognition system design. Even though there are well established algorithms that are generally applicable, the requirement of using certain type of criteria for some practical problems makes most of the resulting methods highly inefficient. In this work, a method is proposed to rank a given set of features in the particular case of Decision Tree classifiers, using the same information generated while constructing the tree. The preliminary results obtained with both synthetic and real data confirm that the performance is comparable to that of sequential methods with much less computation.

¿Se benefician de los programas de intervención que no tratan específicamente el consumo de alcohol los maltratadores con problemas de consumo abusiv…

2013

ResumenEn el ámbito de la intervención con maltratadores y de la investigación en torno a la mejora de la efectividad de estas intervenciones el consumo abusivo de alcohol ha sido uno de los factores de riesgo que ha recibido especial atención. El objetivo de este trabajo es analizar la relación entre el consumo abusivo de alcohol, el proceso de cambio debido a la intervención y el abandono prematuro. Para ello se utilizó una muestra de 86 hombres consumidores de riesgo y 80 hombres no consumidores de riesgo, todos ellos condenados por violencia contra la mujer en las relaciones de pareja y participando en un programa de intervención en medio comunitario que no trata específicamente el prob…

Study of a medium-size biological molecular association by means of a pair potential semiempirical approach: β-carboline-lumiflavin

1985

The molecular association between some substituted β-carbolines and a model flavin, lumiflavin, has been studied by means of a semiempirical approach proposed by Fraga based on a 1/R expansion of atom-atom pair potentials. Only stacked minima have been considered because of their possible biological interest. The calculations characterize 15 different minimum stacked conformations, most of them occurring in the complexes considered. The structural and energetic effects of 1–Me, 6–OH and 7–OH substituents of β-carboline are discussed. An equilibrium conformation involving geometric overlap between the pteridinic portion of flavin and the indole group of β-carboline is predicted to be the mos…

APPLICATION OF 3‐D FINITE DIFFERENCE METHOD FOR INDUCTANCE CALCULATION OF AIR‐CORE COILS SYSTEM

1994

The paper deals with the inductance calculation of air‐core coils system by means of 3‐D analysis of magnetic field of the coils with rectangular cross‐section. The possibility of mutual and self‐inductance calculation is presented. For magnetic field calculation, the Finite Difference Method with application of fast calculating procedures was applied. The method of calculation has been verified by experiments. The obtained difference between calculating and measurement results is equal to a few percent. The computer program is usefull especially for asymmetrical configuration of the coils.
