OBJECTIVES This study developed a smartphone nutritional application (app) for making smart and healthy choices when purchasing food in grocery stores and tested its feasibility, usability, satisfaction and acceptability. METHODS "MyNutriCart" was developed following the ADDIE (analysis, design, development, implementation, and evaluation) model. The goals of the app were to improve food sele...

Roughly 35 three-person teams played the roles of user, customer, and developer in negotiating the requirements of a library information system. Each team was provided with a suggested set of stakeholder goals and implementation options, but were encouraged to exercise creativity in expanding the stakeholder goals and in creating options for negotiating an eventually satisfactory set of system ...

Architectural patterns have an impact on both the structure and the behavior of a system at the architecture design level. However, it is challenging to model patterns’ behavior in a systematic way because modeling languages do not provide the appropriate abstractions and because each pattern addresses a whole solution space comprised of potentially infinite solution variants. In this paper, we...

In the real world, exceptional behavior can be seen in many situations such as security-oriented fields. Such behavior is rare and dispersed, while some of them may be associated with significant impact on the society. A typical example is the event September 11. The key feature of the above rare but significant behavior is its high potential to be linked with some significant impact. Identifyi...

Although the kinetics of hybridization between a soluble polynucleotide and an immobilized complementary sequence have been studied by others, it is almost universally assumed that the interaction between each probe/target pair can be treated as a separate event. This simplifies the mathematics considerably, but it can give a false picture of the extent of hybridization that one achieves at equ...

Identifying sequential patterns in learning activity data can be useful for discovering, understanding, and ultimately scaffolding student learning behaviors in computer-based learning environments. Algorithms for mining sequential patterns generally associate some measure of pattern frequency in the data with the relative importance or ranking of the pattern. However, another important aspect ...

As more people use the Web through a browser to gather and disseminate information, recognizing Web browsing signatures can complement other behavioral biometrics such as keystroke authentication to verify a claim of identity and/or identify persons of interest. The deluge of available digital traces enables the cognitive analysis of behavioral traits that differentiate between users and predic...

Positional behavior is the measurable and observable link between the biology and behavior of an animal in its environment. In this dissertation, I examine ontogenetic patterns of positional behavior in infant, juvenile, and adult white-faced capuchins (Cebus capucinus) and mantled howling monkeys (Alouatta palliata) inhabiting the same tropical forest in Costa Rica. During growth and developme...

This paper focuses on the implementation and evaluation of a set of integrated models for the representation of emergent behavior control patterns in robotic environments. The models have been validated on a custom developed emergent behavior simulator and tested using the CORE-TX (COllaborative Robotic Environment the Timisoara eXperiment) prototype platform. Four metrics (pheromone intensity,...
