(Boston University Computer Science Department, 1993-06-04)Parallel computing on a network of workstations can saturate the communication network, leading to excessive message delays and consequently poor application performance. We examine empirically the consequences of integrating ...
-
(Boston University Computer Science Department, 2000-10-17)We consider challenges associated with application domains in which a large number of distributed, networked sensors must perform a sensing task repeatedly over time. For the tasks we consider, there are three significant ...
-
(Boston University Computer Science Department, 2002-09-08)Formal tools like finite-state model checkers have proven useful in verifying the correctness of systems of bounded size and for hardening single system components against arbitrary inputs. However, conventional applications ...

(Wiley Subscription Services, Inc., A Wiley Company, 2009-3-23)OBJECTIVE: Assessment of disordered eating has uncertain validity across culturally diverse populations. This study evaluated Eating Disorder Examination Questionnaire (EDE-Q) performance in an ethnic Fijian study population. ...
-
(Boston University Computer Science Department, 1995-02-20)A problem with Speculative Concurrency Control algorithms and other common concurrency control schemes using forward validation is that committing a transaction as soon as it finishes validating, may result in a value loss ...
-
(2013-05-07)In their inaugural presidential cycle, Super PACs spent heavily in an attempt to sway voters. Though this spending was widely publicized and served as a major source of controversy, very little evidence has been presented ...

(Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1993-01)Speech can be understood at widely varying production rates. A working memory is described for short-term storage of temporal lists of input items. The working memory is a cooperative-competitive neural network that ...
-
(Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1991-02)This article describes neural network models for adaptive control of arm movement trajectories during visually guided reaching and, more generally, a framework for unsupervised real-time error-based learning. The models ...
-
(Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1997-08)Viapoint (VP) movements are movements to a desired point that are constrained to pass through an intermediate point. Studies have shown that VP movements possess properties, such as smooth curvature around the VP, that are ...
-
(Boston University Computer Science Department, 2009-10-01)In research areas involving mathematical rigor, there are numerous benefits to adopting a formal representation of models and arguments: reusability, automatic evaluation of examples, and verification of consistency and ...

-
(Boston University Computer Science Department, 2005-05-19)We introduce a method for recovering the spatial and temporal alignment between two or more views of objects moving over a ground plane. Existing approaches either assume that the streams are globally synchronized, so that ...
-
(CS Department, Boston University, 2010-11-10)This paper describes the scheduling framework for a new operating system called "Quest". The three main goals of Quest are to ensure safety, predictability and efficiency of software execution. For this paper, we focus on ...
-
(Boston University Computer Science Department, 2004-03-23)This paper presents a new approach to window-constrained scheduling, suitable for multimedia and weakly-hard real-time systems. We originally developed an algorithm, called Dynamic Window-Constrained Scheduling (DWCS), ...
-
(Boston University Computer Science Department, 1997-07-10)We propose a new characterization of protein structure based on the natural tetrahedral geometry of the β carbon and a new geometric measure of structural similarity, called visible volume. In our model, the side-chains ...
-
(Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1996-06)How the brain generates visual percepts is a central problem in neuroscience. We propose a detailed neural model of how LGN and the interblob cortical stream through V1 and V2 generate context-sensitive perceptual groupings ...
-
(Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1998-06)The visual cortex has a laminar organintion whose circuits form functional columns in cortical maps. How this laminar architecture supports visual percepts is not well understood. A neural model proposes how the laminar ...
-
(Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1998-02)This paper describes and evaluates visual looming as a method for monocular range estimation. The looming algorithm is based on the relationship between displacements of the observer relative to an object, and the resulting ...
-
(Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1993-01)This article describes the VITEWRITE model for generating handwriting movements. The model consists of a sequential controller, or motor program, that interacts with a trajectory generator to move a hand with redundant ...
