An asynchronous team (A-Team) is a strongly cyclic network of autonomous agents (workers) and memories (workplaces). Results (trial solutions to computational problems) circulate continually through this network. Agents work in parallel and cooperate by modifying one another's results. We have accumulated a good deal of experience in making the circulating results converge to better solutions o...

One of the core task in multi-view learning is to capture all relations among views. For sequential data, the relations not only span across views, but also extend throughout the view length to form long-term intra-view and cross-view interactions. In this paper, we present a new memory augmented neural network model that aims to model these complex interactions between two sequential views tha...

Line tracing, which has been conjectured to play an important role in the visual perception of connectivity relations, is examined in this paper from the computational point of view. The problem is formulated in terms of pixel connectivity, with thin black lines on a white background serving as input. The complexity of line tracing is discussed relative to several computation models. Two algori...

This study explores how student learning via asynchronous, threaded discussion boards may be managed successful. We examine the elements of course scaffolding on that affect student learning and engagement in discussion. We explore the role of the instructor in mediating learning. We base our findings on an analysis of 21 online courses in the IS domain, conducted by multiple instructors over a...

Conquer is an extensible architecture designed for transforming a pull-based data management system (e.g., conventional DBMSs, web search engines and query systems) into a push-enabled data management systems. The key ideas of Conquer are the concept of continual queries; the mechanisms for eecient and scalable implementation of continual queries 20], including synchronous or asynchronous event...

The paper introduces the concept of asynchronous pseudo-system. Its purpose is to correct/generalize/continue the study of the asynchronous systems (the models of the asynchronous circuits) that has been started in [1], [2].

Due to its synchronous behaviour, a strongly-timed program can suffer from the temporary suspension of realtime DSP in the presence of a time-consuming task. In this paper, we propose mostly-strongly-timed programming, which extends strongly-timed programming with the explicit switch between synchronous context and asynchronous context. If a thread is in asynchronous context, the underlying sch...

Asynchronous message-passing system is a standard distributed model, where n processors communicate over unreliable channels, controlled by a strong adaptive adversary. The asynchronous nature of the system and the fact that t < n/2 processors may fail by crashing are the great obstacles for designing efficient algorithms. Leader election (test-and-set) and renaming are two fundamental distribu...
