Shelfaware: Accelerating Collaborative Awareness With Shelf Crdt, John C. Waidhofer
Shelfaware: Accelerating Collaborative Awareness With Shelf Crdt, John C. Waidhofer
Master's Theses
Collaboration has become a key feature of modern software, allowing teams to work together effectively in real-time while in different locations. In order for a user to communicate their intention to several distributed peers, computing devices must exchange high-frequency updates with transient metadata like mouse position, text range highlights, and temporary comments. Current peer-to-peer awareness solutions have high time and space complexity due to the ever-expanding logs that each client must maintain in order to ensure robust collaboration in eventually consistent environments. This paper proposes an awareness Conflict-Free Replicated Data Type (CRDT) library that provides the tooling to support an …
Exploring The Relationship Between Teamwork Skills And Team Members' Centrality, Francisco Cima, Pilar Pazos, Ana Maria Canto
Exploring The Relationship Between Teamwork Skills And Team Members' Centrality, Francisco Cima, Pilar Pazos, Ana Maria Canto
Engineering Management & Systems Engineering Faculty Publications
The present paper describes an exploratory study of small teams working on a four-month project as part of a graduate engineering program. The research had two primary goals. The first was to utilize the log files from shared repositories used for team collaboration to describe the network structure of the teams. The second was to determine whether the network centrality of any individual team member is associated with their teamwork skills and attitudes towards the collaboration platform. The relationship between teamwork skills, attitudes towards the collaboration technology, and the centrality index was explored using Pearson correlations. A total of 35 …
Bim+Blockchain: A Solution To The Trust Problem In Collaboration?, Malachy Mathews, Dan Robles, Brian Bowe
Bim+Blockchain: A Solution To The Trust Problem In Collaboration?, Malachy Mathews, Dan Robles, Brian Bowe
Conference papers
This paper provides an overview of historic and current organizational limitations emerging in the Architecture, Engineering, Construction, Building Owner / Operations (AECOO) Industry. It then provides an overview of new technologies that attempt to mitigate these limitations. However, these technologies, taken together, appear to be converging and creating entirely new organizational structures in the AEC industries. This may be characterized by the emergence of what is called the Network Effect and it’s related calculus. This paper culminates with an introduction to Blockchain Technology (BT) and it’s integration with the emergence of groundbreaking technologies such as Internet of Things (IoT), Artificial …
The James Merrill Digital Archive: Channeling The Collaborative Spirit(S), Shannon Davis, Joel Minor
The James Merrill Digital Archive: Channeling The Collaborative Spirit(S), Shannon Davis, Joel Minor
Central Plains Network for Digital Asset Management
The James Merrill Papers, housed in Washington University Libraries Special Collections, contains manuscripts, drafts, and other materials from the renowned poet. In 2013, work began to digitize and deliver a selection of the Merrill Papers towards his epic poem, The Book of Ephraim. Because the Libraries’ already used Omeka digital exhibit software for a number of projects, the materials were delivered in an Omeka exhibit, The James Merrill Digital Archive. The process of transforming an archival collection into a digital exhibit required the expertise and input of many collaborators including library staff in Special Collections and Scholarly Publishing, and students …
Towards A Framework For Modelling Multimedia Conferencing Calls In The Next Generation Network, Gavin Byrne, Declan Barber
Towards A Framework For Modelling Multimedia Conferencing Calls In The Next Generation Network, Gavin Byrne, Declan Barber
The ITB Journal
This paper is concerned with the creation of a multiparty multimedia conferencing application which can be used in Next Generation Networks. It begins by suggesting ways in which conferencing can be modeled with a focus on separating signaling and media transfer functionality. Enabling technologies which could support the modeling framework derived and which are compatible with Next Generation Network (NGN) principles are reviewed. Finally, a design and implementation for a simple multimedia conferencing application are described.
Leveraging Mobile Context For Effective Collaboration And Task Management In Disaster Response, Faisal Luqman, Martin L. Griss
Leveraging Mobile Context For Effective Collaboration And Task Management In Disaster Response, Faisal Luqman, Martin L. Griss
Martin L Griss
Collaboration and task management is challenging in distributed, dynamically-formed teams, typical in large scale disaster response scenarios. Ineffective collaboration may result in poor performance and possible loss of life. In this paper, we present Overseer, an agent-based system that exploits context information from mobile devices to facilitate collaboration and task allocation. We describe our system architecture and show how mobile context can be used to create dynamic role-based assignments to support collaboration and effective task management.
Application Of Ict - I: Power Optimization Of Relay Channels, F Ahmed, Z Howard
Application Of Ict - I: Power Optimization Of Relay Channels, F Ahmed, Z Howard
International Conference on Information and Communication Technologies
Relaying in wireless communication can improve power and quality of service. Multiple nodes share channel resources to achieve optimized power. We consider a model with fixed source, destination and relay nodes. Our model finds the optimal values for power transmission for direct and relayed transmitting nodes. In our problem we compare amplify and forward and decode and forward transmission protocols. Unlike other researchers who use constant achievable rates as objective function and power as constraint, we use the strategy of minimizing relay and source power with achievable and target rates as constraints. We simulate various scenarios and our results indicate …
