142	Supporting flexible workflow processes with a progression model Stavness, Nicole Ann 02 March 2005 <body>Users require flexibility when interacting with information systems to contend with changing business processes and to support diverse workflow. Model-based user interface design can accommodate flexible business processes by integrating workflow modelling with other modelling approaches. We present a workflow model, the progression model, to help in developing systems that support flexible business processes. <p> The progression model tracks a users interaction with an application as a set of data elements we refer to as a workflow transaction. The steps a user takes to create a workflow transaction and the state of the workflow transaction at each step is made explicit. By making the workflow status and workflow transaction state explicit, the user can change the order of the steps in a process, manage multiple workflow transactions, keep track of data as it is accumulated, and so on. The intent is to provide the user with a mechanism to deal with partial information, interrupted and concurrent workflow transaction entry, and the processing of multiple workflow transactions. <p> This thesis describes the progression model, an XML-compliant notation to specify the progression model, and a prototype system. </body> Process Model Information System Model-based User Interface Design Use Case Task Model Workflow Model Software Engineering User Interface Description Language Interactive System Data Model Workflow XML Business Process

Dieser Beitrag fokussiert auf Ansätze der räumlichen Analyse, die eine Quantifizierung und Charakterisierung des Gesamtbestandes von Wohn- und Nichtwohngebäuden unterstützen. Vorgestellt werden erste Ergebnisse einer deutschlandweiten Auswertung amtlicher Hauskoordinaten und Hausumringe. Der Gebäudebestand wird nach Bundesländern und nach Raumstrukturtypen des Bundesinstituts für Bau-, Stadt- und Raumforschung (BBSR) gegliedert. Es besteht Bedarf, nicht nur Datenmodelle zu entwickeln, sondern daraus auch Erklärungs- und Messmodelle abzuleiten, die einen expliziten Raumbezug aufweisen und sich zur bestandsorientierten Wissensgewinnung sowie zur Strategieentwicklung eignen – auch im europäischen Kontext.

147	Semantically-enriched and semi-autonomous collaboration framework for the Web of Things : design, implementation and evaluation of a multi-party collaboration framework with semantic annotation and representation of sensors in the Web of Things and a case study on disaster management Amir, Mohammad January 2015 (has links) This thesis proposes a collaboration framework for the Web of Things based on the concepts of Service-oriented Architecture and integrated with semantic web technologies to offer new possibilities in terms of efficient asset management during operations requiring multi-actor collaboration. The motivation for the project comes from the rise in disasters where effective cross-organisation collaboration can increase the efficiency of critical information dissemination. Organisational boundaries of participants as well as their IT capability and trust issues hinders the deployment of a multi-party collaboration framework, thereby preventing timely dissemination of critical data. In order to tackle some of these issues, this thesis proposes a new collaboration framework consisting of a resource-based data model, resource-oriented access control mechanism and semantic technologies utilising the Semantic Sensor Network Ontology that can be used simultaneously by multiple actors without impacting each other’s networks and thus increase the efficiency of disaster management and relief operations. The generic design of the framework enables future extensions, thus enabling its exploitation across many application domains. The performance of the framework is evaluated in two areas: the capability of the access control mechanism to scale with increasing number of devices, and the capability of the semantic annotation process to increase in efficiency as more information is provided. The results demonstrate that the proposed framework is fit for purpose.
148	[en] QEEF: AN EXTENSIBLE QUERY EXECUTION ENGINE / [pt] QEEF: UMA MÁQUINA DE EXECUÇÃO DE CONSULTAS FAUSTO VERAS MARANHAO AYRES 30 June 2004 (has links) [pt] O processamento de consultas em Sistemas de Gerência de Banco de Dados tradicionais tem sido largamente estudado na literatura e utilizado comercialmente com enorme sucesso. Isso é devido, em parte, à eficiência das Máquinas de Execução de Consultas (MEC) no suporte ao modelo de execução tradicional. Porém, o surgimento de novos cenários de aplicação, principalmente em conseqüência do modelo computacional da web, motivou a pesquisa de novos modelos de execução, tais como: modelo adaptável e modelo contínuo, além da pesquisa de modelos de dados semi-estruturados, tal como o XML, ambos não suportados pelas MEC tradicionais. O objetivo desta tese consiste no desenvolvimento de uma MEC extensível frente a diferentes modelos de execução e de dados. Adicionalmente, esta proposta trata de maneira ortogonal o modelo de execução e o modelo de dados, o que permite a avaliação de planos de execução de consultas (PEC) com fragmentos em diferentes modelos. Utilizou-se a técnica de framework de software para a especificação da MEC extensível, produzindo o framework QEEF (Query Execution Engine Framework). A extensibilidade da solução reflete-se em um meta-modelo, denominado QUEM (QUery Execution Meta-model), capaz de exprimir diferentes modelos em um meta-PEC. O framework QEEF pré-processa um meta-PEC e produz um PEC final a ser avaliado pela MEC instanciada. Como parte da validação desta proposta, instanciou-se o QEEF para diferentes modelos de execução e de dados. / [en] Querying processing in traditional Database Management Systems (DBMS) has been extensively studied in the literature and adopted in industry. Such success is, in part, due to the performance of their Query Execution Engines (QEE) for supporting the traditional query execution model. The advent of new query scenarios, mainly due to the web computational model, has motivate the research on new execution models such as: adaptive and continuous, and on semistructured data models, such as XML, both not natively supported by traditional query engines. This thesis proposes the development of an extensible QEE adapted to the new execution and data models. Achieving this goal, we use a software design approach based on framework technique to produce the Query Execution Engine Framework (QEEF). Moreover, we address the question of the orthogonality between execution and data models, witch allows for executing query execution plans (QEP) with fragments in different models. The extensibility of our solution is specified by in a QEP by an execution meta- model named QUEM (QUery Execution Meta-model) used to express different models in a meta-QEP. During query evaluation, the latter is pre-processed by the QEEF producing a final QEP to be evaluated by the running QEE. The QEEF is instantiated for different execution and data models as part of the validation of this proposal.

150	Aplikace systémové dynamiky v managementu zdravotnického zařízení / Application of system dynamics in the management of medical facilities Kastner, Pavel January 2012 (has links) At the present time, characterised by increasing complexity of not just socio-economics systems, decision-making in positions of executive management is becoming increasingly difficult. Although more and more attention is dedicated to use of information and communication technologies in corporate sector and organizations collect unprecedented amount of very detailed data from all areas, their real nature is often not considered. Data, information and knowledge, through which we can achieve real understanding of causes of the observed systems behaviour, are necessary basis for ability for prediction of tomorrow's effects of today's decisions. This thesis aims to highlight the essence of data, information and knowledge in organization and the necessity of systemic perception for creating efficient and effective decisions. The second part of this thesis presents design of system-dynamic model (including user interface), which explains the mechanisms of health care volume accounting in medical facilities with more departments. The model should facilitate understanding of functioning of hospitals by the public, and respect of general nature of medical facilities functioning to create a base for robust model-oriented decision support system for the management.
