PURPOSE We describe changes over time in performance on measures of technical quality and patient experience as a group of primary care clinics transformed themselves into level III patient-centered medical homes. METHODS A group of 21 Minnesota primary care clinics achieving level III recognition as medical homes by the National Committee for Quality Assurance has been tracking a variety of qu...

Model-driven engineering and model transformation have gained significant importance in recent years. However, most model transformation developments are handled without quality in mind. This paper presents a new model transformation design pattern which improves quality in model transformation. We discovered the pattern after solving a specific problem with two alternative model transformation...

This paper discusses data quality challenges in the context of eBusiness Transformation. It presents the major differences between traditional and eBusiness as they relate to business models, organizations, processes and technologies, and then outlines the differences with respect to data quality approaches. The scenarios described pose significant data quality (and other) challenges, and the p...

Adapting software systems at run-time is a key issue, especially when these systems consist of components used as intermediary for human-computer interaction. In this sense, model transformation techniques have a widespread acceptance as a mechanism for adapting and evolving the software architecture of such systems. However, existing model transformations often focus on functional requirements...

Model-Driven Development (MDD) is about treating models as first class design entities. Model-Driven Architecture (MDA) is an Object Management Group’s initiative that proposes to define a set of non-proprietary standards that will specify interoperable technologies with which to realize MDD with automated transformations. The concept of Model-Driven Architecture lies on models at different abs...

This paper presents some related work on quality frameworks and requirements for evaluating them. It also discusses characteristics of modeldriven engineering that are important when building a quality framework, such as its use of models in several stages of development and maintenance, generation of other artifacts from models and its multi-abstraction level approach that requires consistency...

We propose a model that predicts harmonic phases at glottal closure instants. Phases are obtained from the scaled harmonic amplitude envelope derivative. This method is able to generate convincing synthesis results while avoids typical phasiness artifacts. A clear advantage of such model is to simplify the sample concatenation of sample based synthesizers. In addition, it helps to improve the s...
