Software models are key in separating and solving independent development concerns. However, there is still a gap on how to transition design information among these separate, but related models during development and maintenance. This paper addresses the problem on how to maintain the consistency of UML class diagrams during various levels of refinement. We present a new approach to automated ...

The objective of this work was to develop bioadhesive topical gel of Aceclofenac with the help of response-surface approach. Experiments were performed according to a 3-level factorial design to evaluate the effects of two independent variables [amount of Poloxamer 407 (PL-407 = X1) and hydroxypropylmethyl cellulose K100 M (HPMC = X2)] on the bioadhesive character of gel, rheological property o...

Hierarchical Interface-Based Supervisory Control decomposes a large discrete event system into subsystems linked to each other by interfaces, facilitating the design of complex systems and the re-use of components. By ensuring that each subsystem satisfies its interface consistency conditions locally, it can be ensured that the complete system is controllable and nonblocking. The interface cons...

background: sustained visual attention is a prerequisite for learning and memory. the early evaluation of attention in childhood is essential for their school and career success in the future. the aim of this study was to design, development and investigation of psychometric properties (content, face and convergent validity and test-retest and internal consistency reliability) of the computer -...

Scale-out datacenter applications are of enormous commercial interest, yet they are frustratingly hard to build. A common design pattern is to locate most of the application logic in a middle tier of soft-state servers and to provide storage using a separate backend system. The Partitioning and Recovery Service (PRS) is an infrastructure service that makes it easier to build these middle tier a...

This paper describes the Object Synchronizer pattern which decouples object synchronization from object functionality. This pattern supports several synchronization policies and their customization. This pattern is used when invocations to an object need to be controlled in order to preserve its consistency. The solution described by this pattern provides encapsulation, modularity, extensibilit...

This is an investigation into whether and under which conditions consistency between brand name and logo may positively influence consumer attitudes toward brands through three studies. The descriptive design in Study 1 highlights a strong positive correlation between general brand evaluations and brand-logo consistency ratings. Two experiments show that perceived initial consistency between br...

DSM-PM2 is a platform for designing, implementing and experimenting multithreaded DSM consistency protocols. It provides a generic toolbox which facilitates protocol design and allows for easy experimentation with alternative protocols for a given consistency model. DSM-PM2 is portable across a wide range of clusters. We illustrate its power with figures obtained for different protocols impleme...

This paper examines the potential role of unit consistency as a system design principle. Unit-consistent generalized matrix inverses and unit-invariant matrix decompositions are derived in support of this principle. Applications of the methods described are illustrated with examples relating to nonlinear system identification and robustness to multiplicative noise for image database retrieval.
