Pareto-improving congestion pricing and revenue refunding with multiple user classes

Abstract: This study investigates Pareto-improving congestion pricing and revenue refunding schemes in general transportation networks, which make every road user better off as compared with the situation without congestion pricing. We consider user heterogeneity in value of time (VOT) by adopting a multiclass user model with fixed origin–destination (OD) demands. We first prove that an OD and class-based Pareto-improving refunding scheme exists if and only if the total system monetary travel disutility is reduced. In view of the practical difficulty in identifying individual user’s VOT, we further investigate class-anonymous refunding schemes that give the same amount of refund to all user classes traveling between the same OD pair regardless of their VOTs. We establish a sufficient condition for the existence of such OD-specific but class-anonymous Pareto-improving refunding schemes, which needs information only on the average toll paid and average travel time for trips between each OD pair.

Object modeling for user-centered development and user interface design: the wisdom approach

Abstract: ion Presentation Control PAC Aplication Conceptual Interface (ACI) Instantiation of a User Interface System Functional core Output Input User User Functional core Figure II.23 Conceptual Architectural Models for User-interface Objects In the late 1980s and early 1990s several approaches of implementation architectural models for interactive systems emerged. Unlike conceptual models, implementation models organize the interactive system as a set of software components and aim at practical software engineering considerations like reusability, maintainability, and performance. The Seeheim model [Bass, 1992] proposes a simple three-layer model (application, dialogue and presentation) of an interactive system, roughly coupling the semantic, syntactic and lexical functionality’s of the user interface. The application component models the domain-specific components, the dialogue component defines the structure of the dialogue between the user and the application and, finally, the presentation component is responsible for the external to internal mapping of basic symbols. The Seeheim model is considered a correct and useful model for specification of interactive systems [Duce et al., 1991]. However, its support for distribution, concurrency, resource management and performance is recognized to be insufficient. Background: A Brief Survey of Usability Engineering and Object Modeling 58 The Arch model [Pfaff and Haguen, 1985] is a revision of the Seeheim model aimed at providing a framework for understanding of the engineering tradeoffs, specifically, in what concerns evaluating candidate run-time architectures. The Arch model proposes a five-layer approach balanced around the dialogue component. The components of the Arch model are: • The interaction toolkit component implements the physical interaction with the end-user; • The presentation component provides a set of toolkit independent objects; • The dialogue component is responsible for task-level sequencing, providing multiple view consistency, and mapping the between domain specific and user interface specific formalisms; • The domain adapter component implements domain related tasks required but not available in the domain specific component; • The domain specific component controls, manipulates and retrieves domain data and performs other domain related functions.

Morphing social networks based on user context

Abstract: Providing for adaptive networking based on user context is disclosed herein. By way of example, networking usage patterns, preferences and disposition toward a network or network interface can be monitored and analyzed to determine the user context. In some aspects, the usage context can be further modified based on language processing of content of messages sent or received by the user. Once determined, user context can be employed to adapt a composition of a network, including user nodes of the network as well as interface tools for accessing the network, based on the user context. As user use patterns change, the network can be further adapted to account for changes in user context over time, or other suitable user categorizations. Accordingly, the subject disclosure provides a powerful tool for breaking user-software paradigms requiring the user to adapt to the network and network tools.

Interactive audio-visual foreign language skills maintenance system and method

Abstract: A computer, responsive to user input, controls the presentation of an audio-visual work to a user. Through the selection of several interactive learning options, support and reinforcement of the learning process is provided. In particular, the computer interacts with the user to challenge the user's understanding of the audio-visual work. In connection with the presentation of foreign language works, the user interacts with the computer in role playing, transcription, translation, fill-in-the-blanks and speech repetition activities designed to teach the user to speak the foreign language. Furthermore, as the audio-visual work is presented, a computer generated transcription or translation is displayed for user contemplation, and the user may interact with the computer by requesting the display of grammatical, cultural and geographic notes the further assist in the learning process.
