in this paper we consider a resource allocation problem for a satellite network, where variations of fading conditions are added to those of traffic load. Since the capacity of the system is finite and divided in finite portions, the resource allocation problem reveals to be a discrete stochastic programming problem one, which is typically NP-Hard. We propose a new approach based on the minimiz...

High level modeling tools make it possible to synthesize a high performance FPGA design directly from a Simulink model. Accurate estimates of the FPGA resources required provides the system designer important feedback on area and cost, which is valuable even during early design iterations. Previous approaches to hardware resource estimation suffer a combination of inaccuracy, slowness, and/or h...

We focused on two issues: answer selection and confidence estimation. We found that some simple constraints on the candidate answers can improve a pure IR-based technique for answer selection. We also found that a few simple features derived from the questionanswer pairs can be used for effective confidence estimation. Our results also confirmed findings by Dumais et al, 2002 that the World-Wid...

—This paper considers the problem of computational resource allocation for a team of dynamic mobile robots subject to limited communication and processing bandwidth, and uncertain state information. We describe a robot test bed, the Dynabot, that exhibits these constraints and characterize its information flow and state estimation accuracy. These models are used for simulating formation of a gr...

This paper presents an application of the Fluid Stochastic Petri Net (FSPN) formalism for the analysis of the transfer time distribution in peer-to-peer (P2P) file sharing applications. The transfer of the resource follows a successful search; the transfer time is mainly dominated by network characteristics, application characteristics, resource characteristics, and user behavior. The proposed ...

High-performance computing with FPGAs is gaining momentum with the advent of sophisticated High-Level Synthesis (HLS) tools. The performance of a design is impacted by the input-output bandwidth, the code optimizations and the resource consumption, making the performance estimation a challenge. This paper proposes a performance model which extends the roofline model to take into account the res...

We describe BBN’s Question Answering work at TREC 2002. We focus on two issues: answer selection and confidence estimation. We found that some simple constraints on the candidate answers can improve a pure IRbased technique for answer selection. We also found that a few simple features derived from the question-answer pairs can be used for effective confidence estimation. Our results also confi...

Software effort estimation is a critical part of software engineering. Although many techniques and algorithmic models have been developed and implemented by practitioners, accurate software effort prediction is still a challenging endeavor. In order to address this issue, a novel soft computing framework was previously developed. Our study utilizes this novel framework to develop an approach c...

To receive a project contract through competitive bidding, contractors submit a bid price determined by putting a markup on the estimated project cost. Since a bid is inevitably affected by an inaccurate cost estimate, sufficient resources should be allocated to cost estimation. This paper develops a novel optimization model for determining the bid markup and the resource allocation for cost es...

In this paper, we design a real time estimation system in complex system simulation research. The popular simulation technology High Level Architecture (HLA) is introduced. The logical structure of the system is constructed with three levels of data resource, component and application. The main functions of the system are given, including sample collection, real time estimation, result display,...
