O objetivo do presente trabalho foi investigar, empregando testes neuropsicológicos selecionados, a duração dos efeitos benéficos do programa de estimulação multissensorial e cognitiva realizado em idosos vivendo em instituições de longa permanência ou em comunidade. Os participantes do estudo foram idosos institucionalizados (n=20, 75,1 ± 6,8 anos de idade) e não institucionalizados (n=15, 74,1 ± 3,9 anos de idade), com 65 anos de idade ou mais, sem histórico de traumatismo crânio-encefálico, acidente vascular encefálico ou depressão primária, acuidade visual mínima 20/30 mensurada pelo Teste de Snellen e que participaram regularmente do Programa de Estimulação Multissensorial e Cognitiva. Foram realizadas reavaliações em cinco períodos (2, 4, 6, 8 e 12 meses) após a finalização da intervenção multissensorial e cognitiva. Para isso empregou-se o Mini Exame do Estado Mental (MEEM); nomeação de Boston; fluência verbal semântica (FVS) e fonológica (FVF), testes da Bateria Montreal de Avaliação da Comunicação (MAC), Teste de Narrativa “Roubo de Biscoitos” e testes neuropsicológicos selecionados da Bateria Cambridge (CANTAB) incluindo: Triagem Motora (Motor Screening – MOT); Processamento Rápido de Informação Visual (Rapid Visual Information Processing – RVP); Tempo de Reação (Reaction Time - RTI); Aprendizagem Pareada (Paired Associates Learning - PAL); Memória de Trabalho Espacial (Spatial Working Memory - SWM) e Pareamento com Atraso (Delayed matching to sample - DMS). Os resultados apontaram diferenças estatisticamente significativas entre os grupos revelando taxa de declínio cognitivo maior nos idosos institucionalizados. Esses resultados confirmam sugestão anterior de que o ambiente pobre de estímulos somato-motores e cognitivos das instituições de longa permanência aceleram o declínio cognitivo senil. Além disso, a análise das curvas ROC seguido dos cálculos de sensibilidade, especificidade e eficiência para cada teste revelou que os testes da bateria CANTAB para memória e aprendizado espacial pareado assim como para memória espacial de trabalho permitiram a distinção entre os grupos I e NI em todas janelas de reavaliação. Os resultados demonstraram que uma vez cessado o programa de estimulação, se observa em ambos os grupos declínio cognitivo progressivo, com perdas mais precoces e mais intensas nos idosos institucionalizados do que naqueles vivendo em comunidade com suas famílias. Além disso, observou-se que a duração dos efeitos benéficos sobre o desempenho nos testes neuropsicológicos de ambos os grupos é heterogêneo, e que os efeitos de proteção guardam relação estreita com a natureza das oficinas. Por conta disso os escores dos testes de linguagem declinaram mais lentamente. Os resultados reúnem evidências que permitem a recomendação de programas regulares de estimulação somatomotora e cognitiva para idosos institucionalizados com o intuito de promover a redução da taxa de progressão do declínio cognitivo senil.

OBJECTIVE: The aim of this study was to compare by means of McNamara as well as Legan and Burstone's cephalometric analyses, both manual and digitized (by Dentofacial Planner Plus and Dolphin Image software) prediction tracings to post-surgical results. METHODS: Pre and post-surgical teleradiographs (6 months) of 25 long face patients subjected to combined orthognathic surgery were selected. Manual and computerized prediction tracings of each patient were performed and cephalometrically compared to post-surgical outcomes. This protocol was repeated in order to evaluate the method error and statistical evaluation was conducted by means of analysis of variance and Tukey's test. RESULTS: A higher frequency of cephalometric variables, which were not statistically different from the actual post-surgical results for the manual method, was observed. It was followed by DFPlus and Dolphin software; in which similar cephalometric values for most variables were observed. CONCLUSION: It was concluded that the manual method seemed more reliable, although the predictability of the evaluated methods (computerized and manual) proved to be reasonably satisfactory and similar.

The purpose of this research was to compare, by cephalometric analysis (McNamara and Legan & Burstone) the predictive tracings (by methods manual, and by softwares Dentofacial Planner Plus and Dolphin Image) with the post surgical results. Were selected the pre and post surgical lateral telerradiograph (six months after orthognatic surgery) of the 25 long face patients treated with combined orthognatic surgery. Were made the prediction tracings for each method and comparing cephalometrically with the post surgical results. This protocol was repeated once more for the error method evaluation, and the statistical was made by variance analysis and Tuckey overtest. The results show more frequency of the cephalometric values' aproximation of the post surgical results when the manual method (50% of the similarity with the post surgical result), followed of the DFPlus (31,2%) and Dolphin (18,8%) softwares. The experimental condition permits to conclude that the manual method had more precision, although the previsibility of the digital methods was reasonable satisfactory.

This article describes the use of Artificial Intelligence (IA) techniques applied in cells of a manufacturing system. Machine Vision was used to identify pieces and their positions of two different products to be assembled in the same productive line. This information is given as input for an IA planner embedded in the manufacturing system. Therefore, initial and final states are sent automatically to the planner capable to generate assembly plans for a robotic cell, in real time.

Family estate planning is a phrase used to describe the acquisition, enjoyment, and disposition of the family's possessions. The estate plan organizes the resources of the family of an effort to provide for the present and future needs of the family and other heirs. A plan which is started early usually has a better chance of accomplishing the desired objectives.

One of the ways by which the legal system has responded to different sets of problems is the blurring of the traditional boundaries of criminal law, both procedural and substantive. This study aims to explore under what conditions does this trend lead to the improvement of society's welfare by focusing on two distinguishing sanctions in criminal law, incarceration and social stigma. In analyzing how incarceration affects the incentive to an individual to violate a legal standard, we considered the crucial role of the time constraint. This aspect has not been fully explored in the literature on law and economics, especially with respect to the analysis of the beneficiality of imposing either a fine or a prison term. We observed that that when individuals are heterogeneous with respect to wealth and wage income, and when the level of activity can be considered a normal good, only the middle wage and middle income groups can be adequately deterred by a fixed fines alone regime. The existing literature only considers the case of the very poor, deemed as judgment proof. However, since imprisonment is a socially costly way to deprive individuals of their time, other alternatives may be sought such as the imposition of discriminatory monetary fine, partial incapacitation and other alternative sanctions. According to traditional legal theory, the reason why criminal law is obeyed is not mainly due to the monetary sanctions but to the stigma arising from the community’s moral condemnation that accompanies conviction or merely suspicion. However, it is not sufficiently clear whether social stigma always accompanies a criminal conviction. We addressed this issue by identifying the circumstances wherein a criminal conviction carries an additional social stigma. Our results show that social stigma is seen to accompany a conviction under the following conditions: first, when the law coincides with the society's social norms; and second, when the prohibited act provides information on an unobservable attribute or trait of an individual -- crucial in establishing or maintaining social relationships beyond mere economic relationships. Thus, even if the social planner does not impose the social sanction directly, the impact of social stigma can still be influenced by the probability of conviction and the level of the monetary fine imposed as well as the varying degree of correlation between the legal standard violated and the social traits or attributes of the individual. In this respect, criminal law serves as an institution that facilitates cognitive efficiency in the process of imposing the social sanction to the extent that the rest of society is boundedly rational and use judgment heuristics. Paradoxically, using criminal law in order to invoke stigma for the violation of a legal standard may also serve to undermine its strength. To sum, the results of our analysis reveal that the scope of criminal law is narrow both for the purposes of deterrence and cognitive efficiency. While there are certain conditions where the enforcement of criminal law may lead to an increase in social welfare, particularly with respect to incarceration and stigma, we have also identified the channels through which they could affect behavior. Since such mechanisms can be replicated in less costly ways, society should first try or seek to employ these legal institutions before turning to criminal law as a last resort.

Nelle smart cities moderne, la mobilità di veicoli elettrici (EV) è considerata un fattore determinante nella riduzione del consumo di combustibili fossili e conseguenti emissioni inquinanti. Tuttavia, nonostante gli interessi e investimenti a livello globale, l'accettazione da parte degli utenti è ancora bassa, principalmente a causa della mancanza di infrastrutture e servizi a supporto dei guidatori di EV. Queste mancanze sono la causa principale della cosiddetta range anxiety (timore che il veicolo non abbia autonomia sufficiente per raggiungere la destinazione) e hanno portato al preconcetto che gli EV siano adatti alla sola percorrenza di brevi tragitti. Per contrastare questi problemi, in questo documento è proposta un'applicazione di route planning che supporti mobilità di EV anche su percorsi medio-lunghi, mediante utilizzo di un modello di predizione del consumo energetico e considerazione dell'eventuale necessità di ricarica. Saranno descritte tecniche per determinare il tragitto che un EV sia in grado di percorrere per arrivare a destinazione, in considerazione di restrizioni energetiche, fattore altimetrico del percorso ed eventuali operazioni di ricarica necessarie. Il modello di consumo e l'algoritmo che determina il miglior percorso (dal punto di vista energetico) sono implementati da un web service che interagisce con i servizi di Google Maps (per ottenere indicazioni stradali, dati altimetrici e informazioni in tempo reale sul traffico) e con servizi che offrono informazioni sulle stazioni di ricarica e relative posizioni. Dopo aver descritto il modello di consumo e l'algoritmo per la ricerca del percorso, sarà presentata l'architettura del servizio implementato. Sarà quindi fornita una valutazione del servizio, analizzandone performance e scalabilità, nonché l'efficacia nel supporto di percorsi di EV all'interno di scenari su larga scala (nello specifico la regione Emilia Romagna), attraverso tecniche di simulazione.

In vielen Bereichen der industriellen Fertigung, wie zum Beispiel in der Automobilindustrie, wer- den digitale Versuchsmodelle (sog. digital mock-ups) eingesetzt, um die Entwicklung komplexer Maschinen m ̈oglichst gut durch Computersysteme unterstu ̈tzen zu k ̈onnen. Hierbei spielen Be- wegungsplanungsalgorithmen eine wichtige Rolle, um zu gew ̈ahrleisten, dass diese digitalen Pro- totypen auch kollisionsfrei zusammengesetzt werden k ̈onnen. In den letzten Jahrzehnten haben sich hier sampling-basierte Verfahren besonders bew ̈ahrt. Diese erzeugen eine große Anzahl von zuf ̈alligen Lagen fu ̈r das ein-/auszubauende Objekt und verwenden einen Kollisionserken- nungsmechanismus, um die einzelnen Lagen auf Gu ̈ltigkeit zu u ̈berpru ̈fen. Daher spielt die Kollisionserkennung eine wesentliche Rolle beim Design effizienter Bewegungsplanungsalgorith- men. Eine Schwierigkeit fu ̈r diese Klasse von Planern stellen sogenannte “narrow passages” dar, schmale Passagen also, die immer dort auftreten, wo die Bewegungsfreiheit der zu planenden Objekte stark eingeschr ̈ankt ist. An solchen Stellen kann es schwierig sein, eine ausreichende Anzahl von kollisionsfreien Samples zu finden. Es ist dann m ̈oglicherweise n ̈otig, ausgeklu ̈geltere Techniken einzusetzen, um eine gute Performance der Algorithmen zu erreichen.rnDie vorliegende Arbeit gliedert sich in zwei Teile: Im ersten Teil untersuchen wir parallele Kollisionserkennungsalgorithmen. Da wir auf eine Anwendung bei sampling-basierten Bewe- gungsplanern abzielen, w ̈ahlen wir hier eine Problemstellung, bei der wir stets die selben zwei Objekte, aber in einer großen Anzahl von unterschiedlichen Lagen auf Kollision testen. Wir im- plementieren und vergleichen verschiedene Verfahren, die auf Hu ̈llk ̈operhierarchien (BVHs) und hierarchische Grids als Beschleunigungsstrukturen zuru ̈ckgreifen. Alle beschriebenen Verfahren wurden auf mehreren CPU-Kernen parallelisiert. Daru ̈ber hinaus vergleichen wir verschiedene CUDA Kernels zur Durchfu ̈hrung BVH-basierter Kollisionstests auf der GPU. Neben einer un- terschiedlichen Verteilung der Arbeit auf die parallelen GPU Threads untersuchen wir hier die Auswirkung verschiedener Speicherzugriffsmuster auf die Performance der resultierenden Algo- rithmen. Weiter stellen wir eine Reihe von approximativen Kollisionstests vor, die auf den beschriebenen Verfahren basieren. Wenn eine geringere Genauigkeit der Tests tolerierbar ist, kann so eine weitere Verbesserung der Performance erzielt werden.rnIm zweiten Teil der Arbeit beschreiben wir einen von uns entworfenen parallelen, sampling- basierten Bewegungsplaner zur Behandlung hochkomplexer Probleme mit mehreren “narrow passages”. Das Verfahren arbeitet in zwei Phasen. Die grundlegende Idee ist hierbei, in der er- sten Planungsphase konzeptionell kleinere Fehler zuzulassen, um die Planungseffizienz zu erh ̈ohen und den resultierenden Pfad dann in einer zweiten Phase zu reparieren. Der hierzu in Phase I eingesetzte Planer basiert auf sogenannten Expansive Space Trees. Zus ̈atzlich haben wir den Planer mit einer Freidru ̈ckoperation ausgestattet, die es erlaubt, kleinere Kollisionen aufzul ̈osen und so die Effizienz in Bereichen mit eingeschr ̈ankter Bewegungsfreiheit zu erh ̈ohen. Optional erlaubt unsere Implementierung den Einsatz von approximativen Kollisionstests. Dies setzt die Genauigkeit der ersten Planungsphase weiter herab, fu ̈hrt aber auch zu einer weiteren Perfor- mancesteigerung. Die aus Phase I resultierenden Bewegungspfade sind dann unter Umst ̈anden nicht komplett kollisionsfrei. Um diese Pfade zu reparieren, haben wir einen neuartigen Pla- nungsalgorithmus entworfen, der lokal beschr ̈ankt auf eine kleine Umgebung um den bestehenden Pfad einen neuen, kollisionsfreien Bewegungspfad plant.rnWir haben den beschriebenen Algorithmus mit einer Klasse von neuen, schwierigen Metall- Puzzlen getestet, die zum Teil mehrere “narrow passages” aufweisen. Unseres Wissens nach ist eine Sammlung vergleichbar komplexer Benchmarks nicht ̈offentlich zug ̈anglich und wir fan- den auch keine Beschreibung von vergleichbar komplexen Benchmarks in der Motion-Planning Literatur.
