The built up layer thickness in secondary deformation zone is one of the important parameters in metal cutting process. The built up layer (BUL) is formed in second deformation zone near the tool-chip interface in the back of the chip. This parameter influences the tool life and machined surface quality. This BUL should not be confused with the built up edge (BUE). The deformation of the BUL in...

Although critical to health and well-being, relatively little research has been conducted in the organizational literature on linkages between the work-family interface and sleep. Drawing on Conservation of Resources theory, we use a sample of 623 information technology workers to examine the relationships between work-family conflict, family-supportive supervisor behaviors (FSSB), and sleep qu...

Computer-based tools for supporting collaboration, from informal conversations to structured meetings, are becoming commonplace. Different technologies support various techniques for computer conferencing. On the one extreme is asynchronous communication where the participants do not need to be available at the same time in order to communicate. Traditionally, this has taken the form of compute...

We report a preliminary exploration of the effectiveness of motivation-targeted UI design a novel personalized approach to enhance online participation. The empirical setting was Butterflies and Moths of North America (BAMONA), a large-scale citizen science project. Using a combination of design intervention and classification of users based on their collective identification motivation, we sho...

The Cognitive Work Analysis and Ecological Interface Design frameworks have garnered a great deal of attention in recent years. The former is used to analyze a complex work domain to identify the behaviorshaping constraints imposed by the work domain, control tasks, strategies, operator competencies, and socio-organizational factors. The latter informs the design of operator interfaces for comp...

The effect of disjoining pressure between a rigid spherical probe particle (attached to an AFM cantilever) and a liquid interface (e.g., oil/water or air/water) is treated in an analytic manner to describe the total force F exerted on the probe as a function of the distance X of the probe from the rigid substrate (AFM stage) on which the liquid interface resides. Two cases (i) a flat interface ...

The Graphical user interface has traditionally supported personal productivity, efficiency, and usability. With computer supported cooperative work, the focus has been on typical people, doing typical work in a highly rational model of interaction. Recent trends towards mobility, and emotional and universal design are extending the user interface paradigm beyond the routine. As computing moves ...

D. M. Sow J. S. Davis II M. R. Ebling A. Misra L. Bergman In this paper we present SCOUT, an application that examines the machine-generated messages within the in-box of an e-mail application, extracts from these messages information regarding the tasks the recipient is asked to perform, and displays these messages in a graphical interface where they are grouped by context. The tool is intende...

The use of the Internet and social applications has many benefits for the elderly, but numerous investigations have shown that the elderly do not perceive online social networks as a friendly social environment. Therefore, TreeIt, a social application specifically designed for the elderly, was developed for this study. In the TreeIt application, seven mechanisms promoting social interaction wer...
