The research presented h e r e a d d r esses the problem of change impact analysis CIA for object-oriented software. A major problem for developers in an evolutionary environment is that seemingly small changes can ripple throughout the system to have major unintended impacts elsewhere. As a result, software developers need to understand how a change to a(More)
Patients with chronic diseases such as diabetes have to monitor complex sets of medical observations and behaviors. This includes blood glucose, weight, cholesterol, HbA1c, blood pressure, as well as diet, exercise and medication. We have developed a set of web-based, highly interactive graphic modules that are integrated in a personal health record to(More)
The extraction of dynamic motion features are reported from multiple video frames by three unsupervised learning algorithms, i.e., Principal Component Analysis (PCA), Independent Component Analysis (ICA), and Non-negative Matrix Factorization (NMF). Since the human perception of facial motion goes through two different pathways, i.e., the lateral fusifom(More)
Insulin resistance in metabolic syndrome subjects is profound in spite of muscle insulin receptor and insulin-responsive glucose transporter (GLUT4) expression being nearly normal. Insulin receptor tyrosine kinase phosphorylation of insulin receptor substrate-1 (IRS-1) at Tyr896 is a necessary step in insulin stimulation of translocation of GLUT4 to the(More)
We describe how we built a model for user decision-making during local search tasks, specifically hotels. We differentiate between affective and functional needs and identify the following stages and related information needs: 0. Lay of the land; 1. Generating options; 2. Scanning for attractors and detractors; 3. Due diligence. We contrast this framework(More)
• The degree of interdependence between two or more components. – Reducded coupling Þ Reduced Complexity • Make components as independent as possible. – Eliminate unnecessary relationships – Ease the tightness of necessary relationships. • The fewer the connection, the less chance there is for the ripple effect. – Ideally, changing one component should not(More)
Although categorization is fundamental to speech processing, little is known about the learning systems that mediate auditory categorization and even less is known about changes across the lifespan. Vision research supports dual-learning systems that are grounded in neuroscience and are partially-dissociable. The reflective, rule-based system is(More)
