Communication technology use and well-being: does less screen time lead to greater happiness?
<p>Both positive and negative effects of communication technology use have been studied with contradictory findings. Some research has shown that engagement with this technology can reduce face-to-face interaction, which threatens subjective well-being. Other studies have shown that the right …

Accelerating distributed neural network training with network-centric approach
… distributed training approaches, however, the communication time to periodically exchange parameters (i.e., weights) and gradients among computer nodes over the network constitutes a large fraction of the total training time. To reduce the communication time, we propose an algorithm/hardware …

Formation Fidelity of Simulated Unmanned Autonomous Vehicles through Periodic Communication
… formation operates under ideal conditions. When communication between vehicles is limited, maintaining a formation becomes difficult. In some cases the formation may become unstable. While a control law may stabilize a formation of vehicles with good communication, it may not be able to do so …

Event-Based Control and Estimation with Stochastic Disturbances
… (LTI) control is with a single loop a greatly reduced communication rate, which with multiple loops can be traded for a similarly reduced regulation error. With the bottleneck that sensors report only intervals, both the theoretical and practical control problems become more complex. We focus …

Reducing communication in sparse solvers
… is limited by irregular point-to-point communication. Multiple methods are investigated throughout this dissertation for reducing the cost associated with communication throughout sparse matrix operations. Algorithmic changes reduce communication requirements, but also affect accuracy of …

Algorithms and Systems for Scalable Multi-Agent Geometric Estimation
… conditioning. On the other hand, realworld communication networks impose operational constraints (e.g., in the form of available bandwidth) that need to be accounted for during deployment. This thesis develops algorithms and systems toward enabling scalable collaborative geometric …

The PowerPoint Society: The Influence of PowerPoint in the U.S. Government and Bureaucracy
… style of presentation has become the norm of communication, and in doing so, has replaced other methods of discursive and presentation. The art of the brief and in particular, the art of the PowerPoint has become a new standard of what was once group communication through oratory. This paper …

Appreciative Inquiry summits and organizational knowledge creation: A social systems perspective
… through an ongoing production of decision communications. An AI summit consists of three different types of systems that co-evolve and are structurally coupled: an organization system, interaction system and the individual participants’ psychological systems. I propose a typology for …

Nurses' Perceptions of the Effects of Disruptive Physician Behavior on Patient Safety
… it occurs in healthcare the stakes are elevated. Communication breakdown has been identified as a factor that contributes to medical errors and disruptive behavior is a potential cause of communication breakdown. The Institute of Medicine (IOM) estimated in 1997 that in the United States there …

Improving Infectious Tuberculosis Education and Counselling in Calgary for Patients who are Foreign-born and their Families
… and counselling, there was evidence that communication problems had occurred. TB HCWs reported numerous, multi-level barriers to providing education and counselling but found that continuity of care and clear information provided early reduced communication problems. Data from community …

Probabilistic methods for distributed information dissemination
… with inherent unreliabilities. This makes many communication, coordination and computation tasks challenging and in many scenarios communication becomes a crucial bottleneck. In this thesis, we develop new algorithms and techniques to address these challenges. In particular we concentrate on …

Congestion Control for V2V Communication in VANET
… which can result in packet loss, delays, and reduced communication reliability. This dissertation focuses on addressing the congestion control challenge by exploring both traditional and innovative machine learning-based approaches, with the goal of improving communication efficiency while …

White matter connectivity, cognition, symptoms and genetic risk factors in Schizophrenia
… structural connectome; overall these suggest a reduced communication between distal brain regions. Schizophrenia is characterised by persistent cognitive impairments that predate the occurrence of symptoms and have been shown to have a neural foundation reflecting aberrant brain connectivity. So …

Scheduling Memory Transactions in Distributed Systems

Efficient projection space updates for the approximation of iterative solutions to linear systems with successive right hand sides
Accurate initial guesses to the solution can dramatically speed convergence of iterative solvers. In the case of successive right hand sides, it has been shown that accurate initial solutions may be obtained by projecting the newest right hand side vector onto a column space of recent prior …
