In the early 1990s, the effectiveness and ef®ciency of the information systems (IS) supporting the US Department of Defense's non-combat operations was questioned. As had many organizations, the support had evolved into multiple, redundant, unintegrated, undocumented, stove-piped IS. These systems require unnecessarily large non-combat IS expenses, supporting war ®ghting efforts. Lack of integr...

BACKGROUND Managing change has not only been recognized as an important topic in medical informatics, but it has become increasingly important in translational informatics. The move to share data, together with the increasing complexity and volume of the data, has precipitated a transition from locally stored worksheet and flat files to relational data bases with object oriented interfaces for ...

Requirements Elicitation requires a data scientist to communicate with a customer. A typical result of a requirements elicitation process in Software Engineering is an SRS (System Requirements Specification) document. For Data Science projects, there may not be an explicit need for a formal written SRS. However, it may be benefitial to record observations made during the process, if without the...

In this paper we present a multimodal interface that employs speech recognition and eye gaze tracking technology for use in data entry tasks. The aim of this work is to compare the usability of this multimodal system against other data entry methods (handwriting, mouse and keyboard and speech only) when carrying out the data entry task of filling a form. Discussions regarding the relationships ...

All 50 US states allow medical exemptions from school entry immunization requirements. The extent to which medical exemptions are granted and the relationship with ease of obtaining these exemptions has not previously been examined in detail. We evaluated counts and rates of state-level medical exemptions to kindergarten entry requirements over 7 school years (2004-2005 through 2010-2011). Duri...

Estimation of the entry capacity of roundabouts greatly varies between one method and another in their input requirements, model complexity and estimate accuracy. Several available models for the capacity estimation at approach entries of the roundabouts are tested here and compared for high traffic demand condition. The estimated entry capacities along with the actual entry demand are then com...
