During a revisit to modal identification in the past three decades, an overview of the major developments and issues in modal identification is motivated. A brief review on the progress from Single-Input/Single-Output (SISO), Single-Input/Multi-Output (SIMO) to Multi-Input/Multi-Output (MIMO) identification in frequency, time and spatial domain, is presented. The latest developments and issues ...

one main group of a transportation network is a discrete hub covering problem that seeks to minimize the total transportation cost. this paper presents a multi-product and multi-mode hub covering model, in which the transportation time depends on travelling mode between each pair of hubs. indeed, the nature of products is considered different and hub capacity constraint is also applied. due to ...

The actual usability of a Virtual Environment (VE) depends to a large extent on the multi-modal interaction interfaces. A multi-modal interaction system combines visual information with many interaction methods to provide flexible and powerful dialogue approaches, thus enabling users to choose single or multiple interactions. This paper is a review of existing multi-modal interaction interfaces...

Recently, many studies have tried to find travel patterns to understand citizen’s movement behaviours and improve transportation services based on the big data in public transportation systems. This research introduces a method of discovering and evaluating spatial movement patterns from smart card transaction data of multi-modal transportation networks such as subway and bus. The transaction d...

In this paper, we propose a novel multiscale approach to model Virtual Urban Environments thanks to the introduction of a design pattern which links activity places and transportation networks. This environment is also augmented with a synthetic population in order to build the Populated Urban Environment. The meso-simulator TransNetSim has been developed and coupled with the micro-simulator Vi...

One of tha principal goals of tha TAXMAN project is to develop a theory about the structure and dynamics of legal concapts, using corporate tax law as an experimental problem domain In this paper we describe the "prototype* plus-deformation" model of legal conceptual structure a concept is represented here by a prototypical description plus a sequence of deformations of the prototype, where the...

We present an information theoretic approach to multi-modal signal processing, and validate the framework with illustrative examples from medical image processing and multi-media signal processing. The approach tries to adaptively identify that pair of feature space representations of a pair of multi-modal signals which carries maximal redundancy. Analogously, we can say that the framework extr...

The research described in this paper focuses on the application of modal strain techniques on a multi-girder bridge superstructure with the objectives of identifying the presence of damage and detecting false damage diagnosis for such structures. The case study is a one-third scale model of a slab-on-girder composite bridge superstructure, comprised of a steel-free concrete deck with FRP rebars...

Current research suggests that vehicle emission rates are highly correlated with modal vehicle activity and that specific instances of load-induced enrichment may contribute a disproportionate share of motor vehicle emissions. Consequently, researchers have been developing a variety of modal modeling approaches to transportation-related air quality modeling. Modal models predict emissions as a ...
