Entity Resolution (ER) has been one of the bedrocks in the creation of information systems by ensuring ambiguous entities are identified and resolved by linking. One common design approach of traditional ER systems is to run in single-threaded mode, which makes the system prone to out-of-memory error when processing larger datasets. The Data…

Data visualization is a powerful strategy for using graphics to represent data for effective communication and analysis. Unfortunately, creating effective data visualizations is a challenge for both novice and expert design users. The task often involves an iterative process of trial and error, which by its nature, is time-consuming. Designers…

Modern Information Technology (IT) infrastructure and open-source software (OSS) have revolutionized our ability to access and process data, enabling us to tackle increasingly complex problems and challenges. While these technologies provide substantial benefits, they often expose users to vulnerabilities that can severely damage individuals and…

High schools must format the master schedules and designate a specific number of instructional minutes to help promote student growth. School leaders that attempt to enhance Pennsylvania Value-Added Assessment growth scores need an opportunity to utilize a master schedule that fits their needs and to support continued growth. With the emergence of…

Graph data, especially large graph data, come up in many domains, such as social networks, the map of science, biological data, and even knitting! This presents a problem when we consider visualizing these structures. Layouts must be chosen carefully so that the structure of the graph is visible. Some graphs are large enough and connected enough…

As higher education institutions go online to reap the benefits of technology and align their programs with a world economy that is increasingly becoming digital, the multimedia learning theory warns of possible challenges. Large device screens have been used to present related information elements of a learning task simultaneously to facilitate…

The purpose of this comparative, longitudinal case study was to explore the distance operations system implemented in U.S. colleges and universities during the COVID-19 pandemic. Embedded in a larger two-year study of distance education in the U.S. before and after the health crisis, this study combined a grounded theory methodology with a…

The efficacy of intelligent tutoring systems (ITS) for undergraduate college level courses was not well established and specifically, the Pearson Dynamic Study Modules (PDSM) program had not been investigated locally. The purpose of this quantitative study was to determine whether the use of an ITS designed with a cognitive learning approach; the…

Hands-on laboratory experiences are a key part of all engineering programs. Currently there is high demand for online engineering courses, but offering lab experiences online still remain a great challenge. Remote laboratories have been under development for more than 20 years and are part of a bigger category, called online laboratories, which…

Massive open online courses provide virtually unlimited numbers of learners with access to instructors and course materials from high-status institutions. These courses are technologically intensive in ways that traditional online courses are not, which invites an examination of how the work to create these new forms may or may not work within…

Classroom management has many challenges, but when the class is held in a computer lab, even more challenges surface. The obstruction of the line-of-sight between the instructor and the students makes it difficult to monitor student behavior, attention, facial expressions or other non-verbal cues. Also, while the computer is a powerful machine,…

The Science DMZ is a network research tool offering superior large science data transmission between two locations. Through a network design that places the Science DMZ at the edge of the campus network, the Science DMZ defines a network path that avoids packet inspecting devices (firewalls, packet shapers) and produces near line-rate transmission…

Digital ecosystems are one of the most important strategic issues in the current digital economy. Digital ecosystems are dynamic and generative. They evolve as new firms join and as heterogeneous systems are integrated into other systems. These features digital ecosystems determine economic and technological success in the competition among…

Researchers have spent years understanding resource utilization to improve scheduling, load balancing, and system management through short-term prediction of resource utilization. Early research focused primarily on single operating systems; later, interest shifted to distributed systems and, finally, into web services. In each case researchers…

Heterogeneous design presents an opportunity to improve energy efficiency but raises a challenge in management. Whereas prior work separates the two, we coordinate heterogeneous design and management. We present a market-based resource allocation mechanism that navigates the performance and power trade-offs of heterogeneous architectures. Given…
