Contextualized B2B Registries
No full textAbstract. Service discovery is a fundamental concept underpinning the move towards dynamic service-oriented business partnerships. The business process for integrating service discovery and underlying registry technologies into business relationships, procurement and project management functions has not been examined and hence existing Web Service registries lack capabilities required by business today. In this paper we present a novel contextualized B2B registry that supports dynamic registration and discovery of resources within management contexts to ensure that the search space is constrained to the scope of authorized and legitimate resources only. We describe how the registry has been deployed in three case studies from important economic sectors (aerospace, automotive, pharmaceutical) showing how contextualized discovery can support distributed product development processes
Test exploration and validation using transaction level models
No full textThe complexity of the test infrastructure and test strategies in systems-on-chip approaches the complexity of the functional design space. This paper presents test design space exploration and validation of test strategies and schedules using transaction level models (TLMs). Since many aspects of testing involve the transfer of a significant amount of test stimuli and responses, the communication-centric view of TLMs suits this purpose exceptionally wel
The Price of Oil
No full textDrawing on their extensive knowledge of the oil industry, Roberto F. Aguilera and Marian Radetzki provide an in-depth examination of the price of the world's most important commodity. They argue that although oil has experienced an extraordinary price increase over the past few decades, we have now reached a turning point where scarcity, uncertain supply and high prices will be replaced by abundance, undisturbed availability and suppressed price levels. They look at the potential of new global oil revolutions to bring the upward price push to an end and examine the implications of this turnaround for the world economy, as well as for politics, diplomacy, military interventions and the efforts to stabilize climate. This book will appeal to a wide readership of both academics and professionals working in the energy industry, as well as to general readers interested in the ongoing debate about oil price
B2B Infrastructures in the Process of Drug Discovery and Healthcare
No full textIn this paper we describe a demonstration of an innovative B2B infrastructure which can be used to support collaborations in the pharmaceutical industry to achieve the drug discovery goal. Based on experience gained in a wide range of collaborative projects in the areas of grid technology, semantics and data management we show future work and new topics in B2B infrastructures which arise when considering the use of patient records in the process of drug discovery and in healthcare applications
Model-driven system validation by scenarios
No full textThe chapter presents a method for scenario-based validation of embedded system designs provided in terms of UML models. This approach is based on model transformations from SystemC UML graphical models into Abstract State Machine (ASM) formal models, and exploits the scenario-based model validation of the ASMs. This validation approach complements an existing model-driven design methodology for embedded systems based on the SystemC UML profile. A validation tool integrated into an existing model-driven co-design environment to support the proposed scenario-based validation flow is also presented. It allows the designer to functionally validate system components from SystemC UML designs early at high levels of abstraction
A SystemC-based framework for modeling and simulation of networked embedded systems
No full textNext-generation networked embedded systems pose new challenges in the design and simulation domains. System design choices may affect the network behavior and Network design choices may impact on the System design. For this reason, it is important --at the early stages of the design flow-- to model and simulate not only the system under design, but also the heterogeneous networked environment in which it operates. For this purpose, we have exploited a modeling language traditionally used for System design --SystemC-- to build a System/Network simulator named SystemC Network Simulation Library (SCNSL). This library allows to model network scenarios in which different kinds of nodes, or nodes described at different abstraction levels, interact together. The use of SystemC as unique tool has the advantage that HW, SW, and network can be jointly designed, validated and refined. As a case study, the proposed tool has been used to simulate a sensor network application and it has been compared with NS-2, a well-known network simulator; SCNSL shows nearly two-order-magnitude speed up with TLM modeling and about the same performance as NS-2 with a mixed TLM/RTL scenario. The simulator is partially available to the community at http://sourceforge.net/projects/scnsl/
Structural change in world metal industries
No full textThe circumstances under which the metal industries operate in the late 1980s are different from those of 10 to 15 years ago. During this period a number of structural shifts have taken place and most have had a negative impact on producers. The author examines some of these shifts and discusses how they have influenced the metal producing industries.</p
Utsikter för Sovjetunionens energiexport efter perestrojkan
No full textThe prospects for the Soviet energy sector are analyzed and the following questions discussed: How will the continued reformation of the society affect the energy sector, how will production and consumption change, will the exportable surplus increase and what will the consequences be for the world energy markets.^The author foresees a very large increase in Soviet energy export after the reform period, wih largest growth of natural gas export and smallest of coal exports</p
