Ubiquitous Substitution

چکیده
Ubiquitous interaction places the user in the centre of dynamic configurations of technology, where work not necessarily is performed through a single personal computer, but supported by a multiplicity of technologies and physical devices. This paper presents an activity-theoretically based framework for analyzing ubiquitous substitution, i.e. a set of mediators that are or can be continuously substituted with the purpose of highlighting expected and indented uses, and the conflicts encountered when attempting substitution between them. The paper develops a four-leveled analysis of such mediators, and point towards a minimalist approach to design of ubiquitous interaction.

The Method for Service Recommendation in Ubiquitous Computing
The arrival of ubiquitous computing environment, while providing services in many devices and users has been a lot of movement. In this environment, users want „seamless‟ service. A lot of mobility in ubiquitous computing environment to provide „seamless‟ service to users, many studies was used to substitute the service. An existing service substitution does not considerate the characteristic o...
متن کاملSemantic enabled Resource Discovery, Composition and Substitution in Pervasive Environments
This paper provides a general framework for service discovery, composition and substitution in a mobile adhoc network scenario. Knowledge representation techniques and approaches are exploited and adapted to the highly flexible and variable ubiquitous computing environment. A polynomial algorithm for composing and orchestrating mobile resources is outlined. Also is presented a simple approach t...
متن کامل"Inverse-electron-demand" ligand substitution in palladium(0)-olefin complexes.
Ligand substitution reactions are ubiquitous in transition-metal chemistry and catalysis. Investigation of ligand substitution reactions for a series of electron-rich palladium(0)-olefin complexes, (bathocuproine)Pd(nitrostyrene) reveals an unprecedented mechanism in which the metal serves as the nucleophilic partner in an "associative" substitution pathway.
متن کاملm-jUDDI+: a Semantic-enabled Service Registry for Discovery, Composition and Substitution in Pervasive Environments
Abstract. We present a semantic-based version of UDDI registry, specifically devised for pervasive environments, able to cope with automated mobile service discovery and composition and compliant with Semantic Web technologies. The framework exploits non-standard inference services within OWL-S. The approach also deals with effect duplication and non-exact matches, computing an approximate cove...
متن کاملFrom E-learning to Ubiquitous Learning; Theoretical Principles
Background: Because of approaches to learning in every place and at any time, ubiquitous learning with knowledge of the context and framework, and due to the development of wireless technologies and sensors, the learning process has changed. Mobile learning and ubiquitous learning as models of e-learning that refer to the acquisition of knowledge, attitudes and skills through wireless technolog...
