I applied well-known hierarchical clustering algorithms to datasets of workstation activity during fiveminute intervals recorded over periods of time ranging from 9 days to one month. I grouped together workstations into ventilation subsystems based on the usage data as well as static pressure values measured in the factories. In simulations, I achieved significant energy savings even when the ...

In 2012, 41 touchscreen tablets were given to children in two villages in rural Ethiopia. These villages had no schools, and the children had no access to literacy. Nicknamed the ‘literacy tablet’, this technology was intended as an educational delivery mechanism to bootstrap reading. The tablet was designed to help remotely located rural children teach themselves to read. Throughout the year-l...

This analysis aims to determine whether parent drug use during childhood is associated with having drug-using networks in adulthood after adjusting for individual adult drug use. METHODS 650 young adult dru...

The advertising industry is seeking to use the unique data provided by the increasing usage of mobile devices and mobile applications (apps) to improve targeting and the experience with apps. As a consequence, understanding user behaviours with apps has gained increased interests from both academia and industry. In this paper we study user app engagement patterns and disruptions of those patter...

This paper describes the use of web based and freeware tools for a cross-discipline research consortium to support graduate education. The use of WordPress and Simple Machine Forums as the main environment to provide web support is discussed, as are the use of statistics tools such as R and SAS-JMP. Usage data for these tools are provided.

Designing viable mobile services requires in-depth understanding of how people deal with their mobile phones on a daily basis. Most studies on the use of mobile phones are based on surveys that ask people how often they think they use mobile applications. While such survey studies have provided numerous insights, they also pose issues of recall, accuracy and common method bias. Fortunately, sma...

Different actors like teachers, course designers and content providers need to gain more information about the way the resources provided with Moodle are used by the students so they can adjust and adapt their offer better. In this contribution we show that Excel Pivot Tables can be used to conduct a flexible analytical processing of usage data and gain valuable information. An advantage of Exc...

BACKGROUND Although the initiation of injection drug use has been well characterized among at-risk youth, factors that support or impede cessation of injection drug use have received less attention. We sought to identify socioeconomic factors associated with cessation of injection drug use among street-involved youth. METHODS From September 2005 to May 2015, data were collected from the At-Ri...
