Truthful routing for wireless hybrid networks

Abstract: Wireless hybrid networks combine the characteristics of both cellular and mobile ad hoc networks. In wireless hybrid networks, it is often assumed that each individual mobile node faithfully follows the prescribed protocols without any deviation. However, these mobile devices, when owned by individual users, will likely do what is the most beneficial to their owners, i.e., act "selfishly". Therefore, an algorithm or protocol intended for selfish wireless devices must be designed. In this paper, we specifically study how to design routing protocols in wireless hybrid networks with selfish nodes. We first present a VCG-based routing protocol for hybrid networks, and show it is truthful but could be expensive. Then we modify the VCG-based routing protocol to make it more efficient for hybrid networks in term of total payment. However, we prove that nodes could lie up their costs in the modified method. Moreover, we propose a novel routing protocol based on first-price path auctions [N. Immorlica et al, 2005], which can achieve a Nash equilibrium with low total payment

Nonlinear vibrations of rectangular laminated thin plates

Abstract: Using the basic assumption of thin-plate theory, including nonlinear terms in the von Karman sense, the free flexural large-amplitude vibrations of arbitrarily laminated rectangular plates are studied. Full-mode displacement formulation with the aid of Galerkin's approximation is treated for more accurate analyses. The Duffingtype equation is solved by the method of harmonic balance with sufficient number of terms in time series, which is compared with the method of direct numerical integration. The convergence of the number of half waves in the x and y directions and that of time series is established. The nonlinear frequencies for the simply supported with movable edges and fully clamped with immovable edges are compared with the available solutions in the literature.

Student Initiatives and Tutor Responses in a Medical Tutoring System

Abstract: This paper attempts to classify student initiatives and tutor responses in transcripts of human tutoring sessions by looking at the interaction between them. We define a student initiative as any attempt by the student to seize control for changing the course of the dialogue. Student initiatives are classified in four dimensions: the surface form, the communicative goal, the content area, and the degree of certainty expressed. (Does the student hedge or not?) The tutor responses are classified in three dimensions: the surface form, the delivery mode, and the communicative goal. We undertook this research in order to discover how our intelligent tutoring system could respond more intelligently to the student. We are convinced that the recognition of initiatives depends on identification of student plans. This represents a first step in our system toward mixed-initiative dialogue.

The Protection of Databases

Abstract: In Parts I and II of this Paper, the author analyzes the legal protection of databases first in international treaties, in particular the Berne Convention and the WTO TRIPS Agreement, and second under national and regional copyright, sui generis, or other (e.g., tort) law in Europe (both the European Directive on the legal protection of databases of 1996, which was under review, and a number of relevant national laws), the United States, and a number of foreign jurisdictions (Australia, Canada, China, Nigeria, Russia, and Singapore). In Part III, the author provides a critical analysis of the effort to expand the legal protection of databases from both theoretical and empirical perspectives. In his conclusion, the author suggests three paths for the future evolution of the protection of databases at the international level.
