Real-Time Implementation of Non-Linear Physical Models with Modal Synthesis and Performance Analysis

Modal decomposition is a popular analysis approach involving the description of a target system via a bank of resonant oscillators called modes. Early sound synthesis frameworks successfully exploited this idea for the simulation of vibrating objects such as bars, plates and strings. While popular, modal synthesis is often applied to linear systems, since the modes become densely coupled in systems presenting distributed or multiple nonlinearities. In this work, the modal approach is used for the simulation of nonlinearly connected systems. When the nonlinearity is of cubic type, a suitable energy-stable modal update can be derived requiring the solution of a single linear system at each time step. A working plugin written in the C++ programming language is presented. Moreover, the performance of the plugin is analysed considering systems of different dimensions, defining the current limits for a real-time application of these models. The analysis also revealed a linear correlation between the number of modes which compose the systems and the CPU usage necessary for their real-time computation

Aporie e opacità dell’otto per mille: tra interesse pubblico a un pluralismo aperto e interessi specifici alla rigidità del mercato religioso

Religion, like politics and economics, risks fueling various forms of conflict of interest in the State. The constitutional choice to affirm a pluralist (or open) laicit\ue0 aims precisely at avoiding and contrasting potential conflicts of interest caused by religious influences. The contradictions and the unclarities detected by several voices about the "otto per mille" economic support system could be read as indicators that Italy failed to implement a management of the public interest which should guarantee the exclusion of favoritism towards individual interests. The original fault of "otto per mille" system lies in the negotiated nature of the legislation that provides for it; the choice of a bilateral source makes clear the will of the State to operate, for purposes of its political consolidation, a substantial connection with the specific interests of some religious denominations in the acquisition and preservation of advantageous positions. It is therefore hoped an unilateral work of reform by the State, in particular the repeal of the fascist legislation about admitted cults and the promulgation of a general law on religious freedo

Monitoraggio di un gruppo di cervi (Cervus elaphus L.) marcati: uso del territorio in un areale alpino

Al fine di acquisire informazioni sull'uso del territorio in ambiente alpino da parte di cervi selvatici e di cervi allevati in recinto e reintrodotti nell'ambiente naturale, sono stati analizzati gli avvistamenti di 10 cervi marcati in Val Fontana (Provincia di Sondrio). Le dimensioni dello spazio minimo occupato dalle femmine sono risultate mediamente di 358 ettari (comprese tra 28 e 875 ettari). Non si sono evidenziati veri e propri comportamenti migratori stagionali, anche se una cerva si \uc3\ua8 spostata temporaneamente in Val Malenco ed \uc3\ua8 poi riapparsa in Val Fontana. I territori invernali rappresentano una frazione pi\uc3\ub9 piccola di quelli estivi, e sono localizzati a quote generalmente inferiori. La cerva allevata in recinto si \uc3\ua8 rivelata inadatta a rappresentare il comportamento tipico della sua specie, sia dal punto di vista spaziale che sociale

A Foundational View on Integration Problems

The integration of reasoning and computation services across system and language boundaries is a challenging problem of computer science. In this paper, we use integration for the scenario where we have two systems that we integrate by moving problems and solutions between them. While this scenario is often approached from an engineering perspective, we take a foundational view. Based on the generic declarative language MMT, we develop a theoretical framework for system integration using theories and partial theory morphisms. Because MMT permits representations of the meta-logical foundations themselves, this includes integration across logics. We discuss safe and unsafe integration schemes and devise a general form of safe integration

Changes in the fine-scale genetic structure of Finland through the 20(th) century

Information about individual-level genetic ancestry is central to population genetics, forensics and genomic medicine. So far, studies have typically considered genetic ancestry on a broad continental level, and there is much less understanding of how more detailed genetic ancestry profiles can be generated and how accurate and reliable they are. Here, we assess these questions by developing a framework for individual-level ancestry estimation within a single European country, Finland, and we apply the framework to track changes in the fine-scale genetic structure throughout the 20(th) century. We estimate the genetic ancestry for 18,463 individuals from the National FINRISK Study with respect to up to 10 genetically and geographically motivated Finnish reference groups and illustrate the annual changes in the fine-scale genetic structure over the decades from 1920s to 1980s for 12 geographic regions of Finland. We detected major changes after a sudden, internal migration related to World War II from the region of ceded Karelia to the other parts of the country as well as the effect of urbanization starting from the 1950s. We also show that while the level of genetic heterogeneity in general increases towards the present day, its rate of change has considerable differences between the regions. To our knowledge, this is the first study that estimates annual changes in the fine-scale ancestry profiles within a relatively homogeneous European country and demonstrates how such information captures a detailed spatial and temporal history of a population. We provide an interactive website for the general public to examine our results. Author summary We have inherited our genomes from our parents, who, in turn, inherited their genomes from their parents, etc. Hence, a comparison between genomes of present day individuals reveals genetic population structure due to the varying levels of genetic relatedness among the individuals. We have utilized over 18,000 Finnish samples to characterize the fine-scale genetic population structure in Finland starting from a binary East-West division and ending up with 10 Finnish source populations. Furthermore, we have applied the resulting ancestry information to generate records of how the population structure has evolved each year between 1923 and 1987 in 12 geographical regions of Finland. For example, the war-related evacuation of Karelians from Southeast Finland to other parts of the country show up as a clear, sudden increase in the Evacuated ancestry elsewhere in Finland between 1939 and 1945. Additionally, different regions of Finland show very different levels of genetic mixing in 1900s, from little mixed regions like Ostrobothnia to highly mixed regions like Southwestern Finland. To distribute the results among general public, we provide an interactive website for browsing the municipality and region-level genetic ancestry profiles atPeer reviewe
