Content available Quality function deployment for designing collaborative working environments
Pankiewicz M.

Vol. 4, No. 4

EN
This paper presents quality-oriented approach to designing Collaborative Working Environments (CWE) - socio-technical systems, in which technology is mediating human interactions for purposes of group cooperation. Both technical and social aspects of virtual collaboration are characterized by high level of complexity, therefore process of designing CWE’s should benefit from approach supporting such complexity. It will be shown, how the Quality Function Deployment method, used for managing the development of complex products, can be utilized into the process of designing such systems.

Dynamics of the spacecraft with giro-gravitational system of stabilisation, in which the pantograph design deployed in an orbit and containing on the end the concentrated mass is used as the gravitational stabilizer and the carrier of solar batteries, is investigated. The analysis of the obtained information is carried out and graphs that illustrate behaviour of characteristic variables are discussed.

High-temperature solid oxide fuel cells (SOFCs) are considered as suitable components of future large-scale clean and efficient power generation systems. However, at its current stage of development some technical barriers exists which limit SOFC’s potential for rapid large-scale deployment. The present article aims at providing solutions to key technical barriers in SOFC technology. The focus is on the solutions addressing thermal resistance, fuel reforming, energy conversion efficiency, materials, design, and fuel utilisation issues.

W artykule przedstawiono opis zaproponowanej przez autorów symulacyjnej metody weryfikacji i walidacji planów wdrożenia, która na etapie projektowania systemu ułatwia zrozumienie jego dynamicznych aspektów oraz pozwala na wczesne wykrycie błędów projektowych i architektonicznych bez konieczności istnienia rzeczywistych produktów wdrożenia i docelowego środowiska działania. Metoda bazuje na wykorzystaniu topologii (jako planu wdrożenia) oraz języków: UML (opisu środowiska wdrożenia), OCL (opisu ograniczeń) i UAL (do opisu imperatywu semantyk akcji). Środki te pozwoliły na zbudowanie precyzyjnych modeli, zarówno planu wdrożenia, jak i symulacyjnego środowiska do jego badania. Symulację w tej metodzie wykorzystano do badania planów wdrożenia jako środek ich ewaluacji.

Simulation method for verification and validation of deployment plans was presented. Using this approach at the design stage of a system, makes it easier to understand dynamics of the system and allows for early detection of design and architecture errors without the need for an actual product deployment. The method is based on the use of topology model (as a deployment plan) and the following languages: UML (description of deployment environment), OCL (constraints) and UAL (imperative semantic of actions). The use of these languages yielded highly accurate models which are the key element of the simulator. The simulation enabled examination of different deployment plans and selection of the one that met the constraints brought to the target environment.

This research deals with the study the dynamics of the spacecraft with the deployed flexible ring antenna. The deployment is performed after placing the spacecraft into orbit and completion of the preliminary damping by a special jet-propelled system, and after uncaging the gyros of the stabilization system. Primarily the antenna is a pre-stressed tape wound on a special drum. When the drum starts deploying the tape, it takes the shape of an elastic ring of variable diameter. The objective of the study is the mechanical and computational modelling of the spacecraft dynamics. The equations of motion are derived with the use of the Eulerian-Lagrangian formalism with the help of Mathematica 5©. Numerical simulations of the operational mode of the system are conducted. Numerical results indicate that the system used for attitude stabilization ensures the shape of the deployed design and prescribed accuracy of the orientation. Simulation results are presented for the spacecraft model in order to show the effectiveness of the spacecraft and deployment process stabilization.

Intencją autora artykułu jest zaprezentowanie procesu przemieszczenia kontyngentu wojskowego na odległy teatr działań, z uwzględnieniem poszczególnych etapów jego realizacji w świetle obowiązujących standardów i wymagań sojuszniczych. Szczególną uwagę zwrócono na aspekty ekonomiczne towarzyszące procesowi decyzyjnemu oraz wielowariantowość działania, a także na fazę wykonawczą przedsięwzięcia z uwzględnieniem szeregu zagrożeń i sposobów minimalizacji ryzyka ich wystąpienia. Ukazane zostały również problemy związane z organizacją transportu na teatrze działań oraz funkcjonowaniem powietrznych i morskich mostów transportowych.

The main purpose of this article is to present the deployment process of a military contingent to an overseas theatre of operation in the light of NATO standards and requirements. In particular, attention has been drawn to the economic aspects associated with planning and executing an operation and also other important problems connected with supply chain security. An attempt has been made to show the in-theatre transport system organisation including procedures and capabilities of military airlift and sealift.

There are many approaches to IT system modeling known from the literature. None of them is perfect, and each, apart from advantages, exhibits some drawbacks. The fact that a perfect method of system modeling doses not exists, is the main reason, for which one looks for new, better solutions for complex system building and implementation. One of such approaches in the field of system modeling architecture is the approach using topologies for configuration and deployment modeling. In this paper the notion of topology in the field of system modeling is provided together with the concept of using this approach to make the complex IT system production more efficient.

W literaturze opisano wiele podejść do modelowania systemów informatycznych. Niedoskonałość metod modelowania powoduje ciągłe poszukiwanie nowych, lepszych sposobów budowania i wyrażania modeli dla złożonych systemów. Jednym z takich podejść w dziedzinie modelowania architektury systemu jest podejście wykorzystujące topologie. Artykuł przedstawia pojęcie topologii w modelowaniu systemów oraz koncepcja wykorzystania tego podejścia w celu usprawnienia procesu wytwarzania złożonych systemów informatycznych.

We propose a grid programming approach using the ProActive middleware. The proposed strategy addresses several grid concerns, which we have classified into three categories. I. Grid Infrastructure which handles the resource acquisition and creation using deployment descriptors and Peer-to-Peer. II. Grid Technical Services which can provide non-functional transparent services like: fault tolerance, load balancing, and file transfer. III. Grid Higher Level programming with: group communication and hierarchical components. We have validated our approach with several grid programming experiences running applications on heterogeneous Grid resource using more than 1000 CPUs.
