Price dynamics are studied in a dataset of more than 11,000 transactions from large-scale financial markets experiments with multiple risky securities. The aim is to determine whether a few simple principles govern equilibration. We first ask whether price ...
This paper compares three heuristic methods (SA, TS and GA) applied to the optimal location of FACTS devices in a power system. The optimizations are made on three parameters: the location of the devices, their types and their sizes. The FACTS devices are ...
The concept of middleware based architectures for telecommunication services in the broadband, multimedia, and information era is emerging. One representative example is the Telecommunications Information Networking Architecture (TINA), which is characteri ...
Road safety, traffic management, and driver convenience continue to improve, in large part thanks to appropriate usage of information technology. But this evolution has deep implications for security and privacy, which the research community has overlooked ...
We propose a new approach to securing computer networks. With this approach, we achieve security in a fully self-organized manner; by this we mean that to secure a computer network, a security system does not require any kind of certification authority or ...
Contrary to the common belief that mobility makes security more difficult to achieve, we show that node mobility can, in fact, be useful to provide security in ad hoc networks. We propose a technique in which security associations between nodes are establi ...
We use bounds of exponential sums to show that, for a wide class of parameters, the modification of the digital signature algorithm (DSA) scheme proposed by A.K. Lenstra (see Proc. Asiacrypt'96, Lect. Notes in Comp. Sci., vol.1163, p.57-64, 1996) is as sec ...
TINA specifies an open architecture for telecommunication services in the broadband, multimedia, and information era. Its characteristics most relevant for security are a variety of services, a multitude of service providers, a well defined business model, ...
The present invention discloses methods and systems for printing by superposing a metallic ink and transparent inks. These methods and systems are useful for color separating images into superpositions of a metallic ink and transparent inks both for design ...
So far, research on mobile ad hoc networks has been focused primarily on routing issues. Security, on the other hand, has been given a lower priority. This paper provides an overview of security problems for mobile ad hoc networks, distinguishing the threa ...
