This work describes a multi-agent architecture and strategy for trade in simultaneous and related auctions. The proposed SIMPLE Agency combines an integer programming model, machine learning techniques and knowledge engineering strategies to build its decision making process. Some well known problems in trading were identified in order to design the architecture. Each SIMPLE agent is concerned ...

Both cloud and grid are computing paradigms that manage large sets of distributed resources, and the scientific community would benefit from their convergence. This paper proposes a novel computing model, cloudgrid, able to achieve full cloud and grid integration. After presenting its three-layer architecture, the security issues involved are analyzed, proposing a solution based on fine-grained...

Cap-and-trade systems have emerged as the preferred national and regional instrument for reducing emissions of greenhouse gases throughout the industrialized world, and the Clean Development Mechanism — an international emission-reduction-credit system — has developed a substantial constituency, despite some concerns about its performance. Because linkage between tradable permit systems can red...

The M•CORE microRISC architecture has been developed to address the growing need for long battery life among today’s portable applications. In this paper, we will present the low-power design techniques and architectural trade-offs made during the development of this processor. Specifically, we will discuss the initial benchmarking, the development of the Instruction Set Architecture (ISA), the...

In this paper, a high frequency dual PLL for a radio frequency transceiver is proposed. This new PLL architecture, which relaxes the trade off design constrains, consists in two PLL loops that drive the same VCO. The first loop has a high current charge pump that drives the high gain VCO side and is aimed to improve the settling time performance. The second loop has a low current charge pump th...

This paper describes the BBN real-time recognition systems used in the 2004 Rich Transcription (RT) benchmark test for the English Conversational Telephone Speech (CTS) and Broadcast News (BN) tasks. We describe the system architecture, along with the algorithms we used in order to reduce computation with minimal impact on recognition accuracy. Particular choices in the design of the final syst...

The need to execute highly demanding and real-time applications on ambient computing networks will be a big challenge in the future. In this paper we present an Operating Environment (OE) that allows application partitioning on such platforms. The OE decisions are made based on a trade negotiation protocol and energy efficiency and resource matching metrics. The metrics matches application and ...

Content distribution networks, enabled through replicated caching, have enabled broadband content delivery over the wiredInternet. In this paper we propose a wireless content distribution scheme based on a new multi-level storage, access, and distributionarchitecture that is tailored for next generation wireless networks. This scheme significantly outperforms conventional translatio...

Space exploration missions require the design and implementation of space networking that differs from terrestrial networks. In a space networking architecture, communication protocols need to be designed, validated and evaluated carefully to support different mission requirements. As actual systems are expensive to build, it is essential to have a low cost method to validate and verify mission...
