Foams, and particularly the polypropylene foam, are more and more often used in the area of injury protection and passive safety for its energy absorption capacity. This multi-scale material is constituted of mesoscopic beads with a large variability of the material properties. To study the effects of these mesoscopic heterogeneities on both the macroscopic and the local behaviors, numerical si...

Multi-document summarization is a process of automatic generation of a compressed version of the given collection of documents. Recently, the graph-based models and ranking algorithms have been actively investigated by the extractive document summarization community. While most work to date focuses on homogeneous connecteness of sentences and heterogeneous connecteness of documents and sentence...

The mechanical behavior of 3D multi-layered braided composite tubes was analyzed using a multi-scale modelling approach. Considering the braiding parameters and the fiber volume fraction of the composite tubes, firstly a unit-cell of the composites was determined based on the motion of yarn carriers and modeled using TEXGEN software. The unit-cell was imported into finite element software to ca...

Understanding the chemical and physical properties of metal/graphene oxide (M/GO) interfaces is important when GO is used in electronic and electrochemical devices because the metal layer must be firmly attached to GO. Here, permeation of metal from the surface into GO paper bulk at the M/GO interface was observed at room temperature for metals such as Cu, Ag, Ni, Au, and Pt. Cu, Ag, and Ni qui...

Center for Wireless Communications, University of California San Diego, 9500 Gilman Dr. La Jolla, CA 92093-0407, USA – fax: +1-619-534-2486 – e-mail: fzorzi,[email protected] Abstract— The decomposition of networking functions into smaller subsets simplifies implementation and leads to open standards. Nonetheless, in applications such as mobile Wireless ATM, where resources are scarce, protocol...

A Multi Layered Display TM (MLD) uses depth to alter the salience of information. This study considered how the use of depth might influence cursor positioning. As pointing movements to targets may be influenced by flanking nontargets, a MLD was used in an attempt to reduce any distracting effects of non-targets. Participants were 14 skilled computer users who moved a computer cursor using a mo...

Distributed software is usually structured in layers, with some kind of operational control or user interface tasks as the topmost layer, making requests to various layers of servers. Client Server systems and ODP (Open Distributed Processing) systems such as DCE, ANSA and CORBA are structured this way, as are distributed transaction processing systems. Performance and dependability are the two...

Accessing computer resources from off campus has been a continuing problem for both students and faculty, and this problem has been exacerbated by the growth of our graduate program. A multi-layered remote authentication system has been created for use by students and faculty providing the ability to telecommute and gain remote access to these resources. Security concerns have also been address...

The problem of fault diagnosis in the domains of robotics and autonomous systems are unique and interesting. A hidden internal fault affects not only other hardware components, as in any other machine, but also the different layers of abstraction and control in the sensethink-act cycle that the robot carries. We propose to implement a model-based diagnosis approach by utilizing the robot's cont...
