Este trabalho apresenta uma proposta para o compartilhamento de dados entre bases de dados orientadas a objetos, em ambientes de desenvolvimento de projetos. O processo de compartilhamento e realizado através de três fases: separação, evolução e integração de dados. Esta forma de compartilhamento atua através de vínculos entre os objetos de base original com a base produto. Foram definidos seis tipos de vínculos, que são estabelecidos no processo de separação: apenas leitura, isolado, flagrante, mutuamente exclusivo, independente e on-line. Com isso, ambas as bases, respeitando as limitações impostas pelo tipo de vinculo entre as mesmas, podem evoluir separadamente e depois de um determinado tempo realizarem, se conveniente, um processo de reintegração. O processo de compartilhamento de dados tem por unidade de gerenciamento os objetos, compostos de base de dados. Os conceitos apresentados podem ser universalmente aplicados, em qualquer base de dados que efetue gerenciamento sobre a composição de seus objetos. Neste trabalho os conceitos de compartilhamento de dados são exemplificados através do modelo de dados SIRIUS.; This work presents a technique to share data stored in an object-oriented databases aimed at design environments.

Linguagens de programação orientadas a objetos possuem diversas características que facilitam sua utilização frente a outras linguagens imperativas. No projeto e desenvolvimento de software, o mecanismo de herança permite a construção de sistemas na forma incremental e evolutiva, possibilitando a reutilização de códigos já escritos. Também a possível atingir aplicações com bons níveis de segurança e confiabilidade, através do encapsulamento de dados e funções sob forma de objetos, que também representam a unidade básica de execução em uma linguagem orientada a objetos. O mesmo recurso que possibilita níveis elevados de segurança permite que linguagens orientadas a objetos sejam inerentemente distribuídas. Objetos possuem tanto área de dados e código de execução independentes dos demais. Acessos aos dados internos de um objeto somente são possíveis através de mensagens explicitas entre objetos. Neste caso um objeto solicita uma ação específica a outro objeto, podendo ser enviados parâmetros e existir retorno de resultados. Este trabalho apresenta um modelo para construção de uma linguagem orientada a objetos distribuída. O ambiente para suportar a execução ao modelo é compostos por vários nodos de processamento com memórias locais individuais e contando com uma rede de comunicação para troca de mensagens entre os nodos. O modelo e discutido em dois níveis distintos: a nível de linguagem e a nível operacional. A nível de linguagem são analisados os recursos de programação normalmente utilizados em linguagens orientadas a objetos quando implementados em ambientes distribuídos. O ambiente de suporte A execução necessário ao suporte do modelo da linguagem a analisado pelo nível operacional. A apresentação do modelo a nível de linguagem discute as características de uma linguagem orientada a objetos distribuída frente as implementações seqüenciais convencionais.

This paper presents a technique to share the data stored in an object-oriented database aimed at designing environments. This technique shares data between two related databases, called the Original and Product databases, and is composed of three processes: data separation, evolution and integration. Whenever a block of data needs to be shared, it is spread into both databases, resulting in a block on the original database, and another into the Product database, with special links between them controlled by the Object Manager. These blocks do not need to be maintained identical during the evolution phase of the sharing process. Six types of links were defined, and by choosing one, the designer control the evolution and reintegration of the block in both databases. This process uses the composite object concept as the unit of control. The presented concepts can be applied to any data model with support to composite objects.

We examined how the digit forces adjust when a load force acting on a hand-held object continuously varies. The subjects were required to hold the handle still while a linearly increasing and then decreasing force was applied to the handle. The handle was constrained, such that it could only move up and down, and rotate about a horizontal axis. In addition the moment arm of the thumb tangential force was 1.5 times the moment arm of the virtual finger (VF, an imagined finger with the mechanical action equal to that of the four fingers) force. Unlike the situation when there are equal moment arms, the experimental setup forced the subjects to choose between (a) sharing equally the increase in load force between the thumb and virtual finger but generating a moment of tangential force, which had to be compensated by negatively covarying the moment due to normal forces, or (b) sharing unequally the load force increase between the thumb and VF but preventing generation of a moment of tangential forces. We found that different subjects tended to use one of these two strategies. These findings suggest that the selection by the CNS of prehension synergies at the VF-thumb level with respect to the moment of force are non-obligatory and reflect individual subject preferences. This unequal sharing of the load by the tangential forces...

Neuroscientists use many different software tools to acquire, analyze and visualize electrophysiological signals. However, incompatible data models and file formats make it difficult to exchange data between these tools. This reduces scientific productivity, renders potentially useful analysis methods inaccessible and impedes collaboration between labs. A common representation of the core data would improve interoperability and facilitate data-sharing. To that end, we propose here a language-independent object model, named “Neo,” suitable for representing data acquired from electroencephalographic, intracellular, or extracellular recordings, or generated from simulations. As a concrete instantiation of this object model we have developed an open source implementation in the Python programming language. In addition to representing electrophysiology data in memory for the purposes of analysis and visualization, the Python implementation provides a set of input/output (IO) modules for reading/writing the data from/to a variety of commonly used file formats. Support is included for formats produced by most of the major manufacturers of electrophysiology recording equipment and also for more generic formats such as MATLAB. Data representation and data analysis are conceptually separate: it is easier to write robust analysis code if it is focused on analysis and relies on an underlying package to handle data representation. For that reason...

Access-based consumption, defined as transactions that can be market mediated but where no transfer of ownership takes place, is becoming increasingly popular, yet it is not well theorized. This study examines the nature of access as it contrasts to ownership and sharing, specifically the consumer-object, consumer-consumer, and consumer-marketer relationships. Six dimensions are identified to distinguish among the range of access-based consumptionscapes: temporality, anonymity, market mediation, consumer involvement, the type of accessed object, and political consumerism. Access-based consumption is examined in the context of car sharing via an interpretive study of Zipcar consumers. Four outcomes of these dimensions in the context of car sharing are identified: lack of identification, varying significance of use and sign value, negative reciprocity resulting in a big-brother model of governance, and a deterrence of brand community. The implications of our findings for understanding the nature of exchange, consumption, and brand community are discussed.

We consider the problem of detecting a large number of different classes of objects in cluttered scenes. Traditional approaches require applying a battery of different classifiers to the image, at multiple locations and scales. This can be slow and can require a lot of training data, since each classifier requires the computation of many different image features. In particular, for independently trained detectors, the (run-time) computational complexity, and the (training-time) sample complexity, scales linearly with the number of classes to be detected. It seems unlikely that such an approach will scale up to allow recognition of hundreds or thousands of objects. We present a multi-class boosting procedure (joint boosting) that reduces the computational and sample complexity, by finding common features that can be shared across the classes (and/or views). The detectors for each class are trained jointly, rather than independently. For a given performance level, the total number of features required, and therefore the computational cost, is observed to scale approximately logarithmically with the number of classes. The features selected jointly are closer to edges and generic features typical of many natural structures instead of finding specific object parts. Those generic features generalize better and reduce considerably the computational cost of an algorithm for multi-class object detection.

Human beings exhibit rapid learning when presented with a small number of images of a new object. A person can identify an object under a wide variety of visual conditions after having seen only a single example of that object. This ability can be partly explained by the application of previously learned statistical knowledge to a new setting. This thesis presents an approach to acquiring knowledge in one setting and using it in another. Specifically, we develop probability densities over common image changes. Given a single image of a new object and a model of change learned from a different object, we form a model of the new object that can be used for synthesis, classification, and other visual tasks. We start by modeling spatial changes. We develop a framework for learning statistical knowledge of spatial transformations in one task and using that knowledge in a new task. By sharing a probability density over spatial transformations learned from a sample of handwritten letters, we develop a handwritten digit classifier that achieves 88.6% accuracy using only a single hand-picked training example from each class. The classification scheme includes a new algorithm, congealing, for the joint alignment of a set of images using an entropy minimization criterion. We investigate properties of this algorithm and compare it to other methods of addressing spatial variability in images. We illustrate its application to binary images...

Efforts to share resources in collaborative pursuits are hindered by differing data representations, redundant applications, and software incompatibilities. Members of a collaborative effort often span different computational environments and the heterogeneity of contexts disrupts software interoperability. Sharing computational resources has become the focus of many research efforts. Efforts in the 1980s led to the Component Object Model (COM) [Williams, 1998a, 1998b, 1990] and the Common Object Request Broker (CORBA) architectures [Offall et al 1996; OMG, 2003]. In the 1990s both technologies were extended for network support. In recent years, Ian Foster, has phrased the distributed computing problem in terms of sharing computational resources. The grid problem is, "coordinated resource sharing and problem solving in dynamic, multi-institutional virtual organizations", "to support collaborative problem solving in industry, science, and engineering in a data rich environment". [Foster et al, 2001] This work presents a new resource sharing platform architecture for information products that leverages the lessons learned from physical product platforms, the concepts of web services, and grid computing. The platform developed in this thesis integrates the contributions of these three areas into a system that is shown to be more efficient and effective at producing software products.; by Abel Sanchez.; Thesis (Ph.

Object recognition accuracy can be improved when information frommultiple views is integrated, but information in each view can oftenbe highly redundant. We consider the problem of distributed objectrecognition or indexing from multiple cameras, where thecomputational power available at each camera sensor is limited andcommunication between sensors is prohibitively expensive. In thisscenario, it is desirable to avoid sending redundant visual featuresfrom multiple views, but traditional supervised feature selectionapproaches are inapplicable as the class label is unknown at thecamera. In this paper we propose an unsupervised multi-view featureselection algorithm based on a distributed compression approach.With our method, a Gaussian Process model of the joint viewstatistics is used at the receiver to obtain a joint encoding of theviews without directly sharing information across encoders. Wedemonstrate our approach on recognition and indexing tasks withmulti-view image databases and show that our method comparesfavorably to an independent encoding of the features from eachcamera.

The process-based simulation library SALMO-OO represents an object-oriented implementation of mass balance equations for pelagic food webs consisting of diatoms, green algae, blue-green algae and cladocerans, as well as nutrient cycles based on PO4–P, NO3–N, DO and detritus in lakes. It gains its structural flexibility from alternative process representations for algal growth and grazing, and zooplankton growth and mortality. Generic model structures of SALMO-OO were determined for three lake categories classified by circulation types reflecting the local climate and morphometry of lakes, and by trophic states reflecting community structures and habitat properties of lakes. Data of six lakes belonging to either of the three lake categories were used to validate the lake category specific structures of SALMO-OO. The study has demonstrated that: (1) JAVA suits well for object-oriented implementations of ecological simulation libraries, (2) object-oriented simulation libraries facilitate the identification of generic model structures for ecosystem categories.; Friedrich Recknage, Lydia Cetina and Byron Zhang; Copyright © 2008 Elsevier B.V.

We present a novel formulation of fully corrective boosting for multi-class classification problems with the awareness of sharing features. Our multi-class boosting is solved in a single optimization problem. In order to share features across different classes, we introduce the mixed-norm regularization, which promotes group sparsity, into boosting. We then derive the Lagrange dual problems which enable us to design fully corrective multi-class algorithms using the primal-dual optimization technique. We show that sharing features across classes can improve classification performance and efficiency. We empirically show that in many cases, the proposed multi-class boosting generalizes better than a range of competing multi-class boosting algorithms due to the capability of feature sharing. Experimental results on machine learning data, visual scene and object recognition demonstrate the efficiency and effectiveness of proposed algorithms and validate our theoretical findings.; Sakrapee Paisitkriangkrai, Chunhua Shen and Anton van den Hengel

To solve today's problem of the lacking interoperability between disparate command and control (C2) systems, the Ballistic Missile Defense Office is developing a proof-of-concept model. The proof-of-concept model, Common Data Sharing System Infrastructure, allows external command and control systems to store, transfer, and communicate using a common object-oriented database. The Generation One architecture demonstrates that information could be shared in a client-server architecture using a message-based, flat-file means of transferring data. Generation Two uses an object-oriented database to increase the infrastructure's robustness and flexibility to give information on demand. This thesis evaluates the Common Data Sharing System Infrastructure for its potential use in future command and control systems.; NA; NA; U.S. Navy (U.S.N.) author.

Internet évolue avec la société et les nouvelles technologies, mais ses usages restent centrés sur le principe communicationnel de partager ses idées, ses histoires avec d’autres personnes. Comprendre les modes de communication des internautes offre des défis de taille aux chercheurs. Malgré une riche littérature sur les usages d’Internet, peu d’études se sont penchées sur l’analyse en profondeur des habitudes des internautes ordinaires. Cette thèse a pour objet d’étude le partage de contenus en ligne, car il s’agit d’une pratique permettant de réfléchir sur le rapport des usagers à la technologie. En m’inspirant des travaux d’Henri Lefebvre et de Michel de Certeau, je mobilise le concept de la vie quotidienne, concept qui met en lumière les processus à travers laquelle les gens font sens de leur vie. Afin de mieux saisir le quotidien, lequel est mobile, fluide et multiple, des métaphores spatiales tirées d’études des sciences, technologies et société (STS) seront mobilisées. Les concepts d’espace fluide et de feu sont idéaux pour étudier les pratiques de partage de vidéo que l’on peut qualifier de mutables et adaptables. Dans cette thèse, l’accent est mis sur les expériences subjectives des internautes ; ainsi...

This study explores the emergence of triadic interactions through the example of book sharing. As part of a naturalistic study, 10 infants were visited in their homes from 3–12 months. We report that (1) book sharing as a form of infant-caregiver-object interaction occurred from as early as 3 months. Using qualitative video analysis at a micro-level adapting methodologies from conversation and interaction analysis, we demonstrate that caregivers and infants practiced book sharing in a highly co-ordinated way, with caregivers carving out interaction units and shaping actions into action arcs and infants actively participating and co-ordinating their attention between mother and object from the beginning. We also (2) sketch a developmental trajectory of book sharing over the first year and show that the quality and dynamics of book sharing interactions underwent considerable change as the ecological situation was transformed in parallel with the infants' development of attention and motor skills. Social book sharing interactions reached an early peak at 6 months with the infants becoming more active in the coordination of attention between caregiver and book. From 7 to 9 months, the infants shifted their interest largely to solitary object exploration...

Aliasing, or sharing, is prominent in many domains, denoting that two differently-named objects are in fact identical: a change in one object (memory cell, circuit terminal, disk block) is instantly reflected in the other. Languages for modelling such domains should let the programmer explicitly define the sharing among objects or expressions. A DSL compiler may find other identical expressions and share them, implicitly. Such common subexpression elimination is crucial to the efficient implementation of DSLs. Sharing is tricky in embedded DSL, since host aliasing may correspond to copying of the underlying objects rather than their sharing. This tutorial summarizes discussions of implementing sharing in Haskell DSLs for automotive embedded systems and hardware description languages. The technique has since been used in a Haskell SAT solver and the DSL for music synthesis. We demonstrate the embedding in pure Haskell of a simple DSL with a language form for explicit sharing. The DSL also has implicit sharing, implemented via hash-consing. Explicit sharing greatly speeds up hash-consing. The seemingly imperative nature of hash-consing is hidden beneath a simple combinator language. The overall implementation remains pure functional and easy to reason about.; Comment: In Proceedings DSL 2011...

Research in life sciences is increasingly being conducted in a digital and online environment. In particular, life scientists have been pioneers in embracing new computational tools to conduct their investigations. To support the sharing of digital objects produced during such research investigations, we have witnessed in the last few years the emergence of specialized repositories, e.g., DataVerse and FigShare. Such repositories provide users with the means to share and publish datasets that were used or generated in research investigations. While these repositories have proven their usefulness, interpreting and reusing evidence for most research results is a challenging task. Additional contextual descriptions are needed to understand how those results were generated and/or the circumstances under which they were concluded. Because of this, scientists are calling for models that go beyond the publication of datasets to systematically capture the life cycle of scientific investigations and provide a single entry point to access the information about the hypothesis investigated, the datasets used, the experiments carried out, the results of the experiments, the people involved in the research, etc. In this paper we present the Research Object (RO) suite of ontologies...

Businesses should be able to share information among each other irrespective of the platform, operating systems and programming languages. Using Internet as the Information Systems Architecture has many values. Internet is affordable, easily available and is not tied to any specific vendor. Internet is simple and runs under any kind of operating system. Information sharing across the Internet is challenging but rewarding. Data Transfer using the Internet requires structure and discipline. To integrate diverse group of systems we need specialized protocols that can connect different platforms that use different languages together. Extensible Markup Language enables the creation of application dependent vocabulary which can be used to store data and information in a structured fashion. Simple Object Access Protocol can be used to carry information electronically from one end to the other. Simple Object Access Protocol uses the World Wide Web's extensible Markup Language in encoding the message contents and its Hypertext Transport Protocol in carrying the message packet. This thesis work is focused upon sharing of information among enterprises using extensible Markup Language, Simple Object Access Protocol and decentralized database systems. An online Shopping cart application has been implemented using the notion of XML and SOAP. SOAP is used as a protocol to share information between AsiStore and its business partners Store 1 and Store2. XML have been used as a part of the application to drive the shopping cart...
