Für Benutzer ist es im Allgemeinen nicht möglich, für jeden Dienst ein unabhängiges, starkes Passwort zu wählen. Diese Situation legt es nahe, den Nutzern ein Single Sign-on (SSO) anzubieten, das es erlaubt, sich mit nur noch einem Passwort an mehreren Diensten anzumelden. Pseudo-SSO-Systeme müssen nicht vom Dienstanbieter unterstütz werden, und sind daher für den Nutzer sofort nützlich, bei ih...

The purpose of this study was to determine the nature and efficiency of the strategies used by prelingually deafened native signers for the temporary retention of written words with reference to a primary language-coding hypothesis (M. A. Shand, 1982). For the gathering of the data, participants were shown lists of serially presented written target words that they were asked to recognize accord...

A new model for evolving crossover operators for evolutionary function optimization is proposed in this paper. The model is a hybrid technique that combines a Genetic Programming (GP) algorithm and a Genetic Algorithm (GA). Each GP chromosome is a tree encoding a crossover operator used for function optimization. The evolved crossover is embedded into a standard Genetic Algorithm which is used ...

Linguistic and psycholinguistic evidence is presented to support the use of structure-mapping theory as a framework for understanding effects of iconicity on sign language grammar and processing. The existence of structured mappings between phonological form and semantic mental representations has been shown to explain the nature of metaphor and pronominal anaphora in sign languages. With respe...

This paper proposes an alternative approach to the examination of artifacts whose contents must be traceable to promote software quality. The approach places emphasis on media use and media transformations. We suggest that one cannot begin to assign and sustain traceability relations at a micro-level between units of content if the sign systems that have been created and transformed to represen...

Originally published in 2003, this article presents one of the first attempts to provide a systematic summary of the new concept of cultural technique. It is, in essence, an extended checklist aimed at overcoming the textualist bias of traditional cultural theory by highlighting what is elided by this bias. On the one hand, to speak of cultural techniques redirects our attention to material and...

s the proliferation of applications accelerates, users find themselves losing the authentication war; every application that they are introduced to requires its own authentication or login. Some applications do this because they need to identify the user they are dealing with. Other applications do so because they simply do not trust anyone else to conduct authentication for them. The evolution...

The purpose of this research is development of an algorithm for hardware implementation for number recognition applying in speed traffic-sign recognition system for car driving assistant. We recognize the speed limit of the speed traffic-sign using hardware oriented extraction algorithm. The numbers are recognized by comparing their feature values with the recognized features. The proposed hard...

Prosodic structure in sign languages is encoded by articulations of the hands, face, and body. Despite the different physical system, there are many similarities to prosody of spoken language, such as the existence of a prosodic hierarchy, alignment of intonational elements (conveyed by the face) with temporally marked prosodic constituents (conveyed by the hands), and a close relation between ...
