Evidence from sign language strongly supports three positions: (1) language is a coherent system with universal properties; (2) sign languages diverge from spoken languages in some aspects of their structure; and (3) domain-external factors can be identified that account for some crucial aspects of language structure -- uniform and diverse -- in both modalities. Assuming that any of these posit...

OpenID, a standard for Web single sign-on, has been gaining popularity both with Identity Providers, Relying Parties, and users. This paper collects the security issues in OpenID found by others, occasionally extended by the authors, and presents them in a uniform way. It attempts to combine the shattered knowledge into a clear overview. The aim of this paper is to raise awareness about securit...

Although often debated as though it were public law, a FRAND undertaking is a private contract between a patent-holder and an SSO. Applying ordinary principles of contract interpretation to the case of ETSI IPR policy reveals that “interpretations” of FRAND advocated by some authors—including cumulative royalty limits, royalties set by counting patents, or a prohibition on capture by the patent...

This paper presents the details and preliminary results of a saliency-based attention mechanism that is part of an architecture designed to detect and recognise traffic signs from a set of images.

If an ‘ideology’, in its broadest sense, is ‘a system of ideas’, semiotics, the study of sign systems, is predestined to make essential contributions to the study of ideologies. The semiotic approach to the study of ideology begins with an investigation of the concept itself, which has changed considerably in the course of its history. Theoretical semiotics has studied signs of ideologies and i...

We present an accurate and efficient system for traffic sign recognition in a real-world driving scene video. The proposed system uses local structure features to achieve high, illumination-invariant accuracy in detection and recognition. We exploit a property of traffic signs, namely, shared boundary shapes, to enhance the speed and accuracy of the detection step. A multi-level SVM structure i...
