Little work has been done on understanding the articulation patterns of users’ touch and surface gestures, despite the importance of such knowledge to inform the design of gesture recognizers and gesture sets for different applications. We report a methodology to analyze user consistency in gesture production, both between-users and within-user, by employing articulation features such as stroke...

SQL extensions that allow queries to explicitly specify data quality requirements in terms of currency and consistency were proposed in an earlier paper. This paper develops a data quality-aware, finer grained cache model and studies cache design in terms of four fundamental properties: presence, consistency, completeness and currency. Such a model provides an abstract view of the cache to the ...

Khazana is a peer-to-peer data service that supports efficient sharing and aggressive caching of mutable data across the wide area while giving clients significant control over replica divergence. Previous work on wide-area replicated services focussed on at most two of the following three properties: aggressive replication, customizable consistency, and generality. In contrast, Khazana provide...

Some applications require the interactive resolution of a constraint problem by a human user. In such cases, it is highly desirable that the person who interactively solves the problem is not given the choice to select values that do not lead to solutions. We call this property global inverse consistency. Existing systems simulate this either by maintaining arc consistency after each assignment...

The NFSv4 protocol includes features intended to enhance its use in global, wide-area networks. In this paper we describe the design and implementation of a prototype for global name space, transparent migration and fine-grained replication that uses and extends these features. In our system, directory migration and replication use the FS_LOCATIONS attribute to redirect I/O requests. For read/w...

A software design is often modelled as a collection of UML diagrams. There is an inherent need to preserve consistency between these diagrams. Moreover, through evolution those diagrams get modified leading to possible inconsistency between different versions of the diagrams. State-of-the-art UML CASE tools provide poor support for consistency maintenance. To solve this problem, an extension of...

this study aimed at investigating the english textese of iranian efl learners by scrutinizing the linguistic features through a qualitative design. in doing so, 700 messages were collected from 43 ma iranian efl learners of both genders. the features were categorized and analyzed calculating the frequency and percentage. the findings of the study showed that iranian efl students used different ...

the main purpose of this paper is theoretically to design the optimal intervention in the foreign exchange market in iran, which has not been investigated by previous studies. the economic fundamentals are strongly affected by the optimal foreign exchange intervention, the consistency of foreign exchange intervention with other policies and political authorities' beliefs about the interven...

Use cases are the notation of choice for functional requirements documentation, whereas task models are used as a starting point for user interface design. In this paper, we motivate the need for an integrated development methodology in order to narrow the conceptual gap between software engineering and user interface design. This methodology rests upon a common semantic framework for developin...
