The extent to which visual form versus higher-level information is used to identify briefly flashed words is assessed in a perceptual identification task. In this task, a word is briefly flashed, post-masked, and a decision is made between two alternatives. The availability of visual (e.g., case or color) and higher-level information (e.g., abstract letter codes, phonology, and meaning) was man...

We present a suite of tools for visualizing the status and progress of branch-and-bound algorithms for mixed integer programming. By integrating these tools with the open-source codes CBC, SYMPHONY, and GLPK, we demonstrate the potential usefulness of visual representations in helping a user predict future progress of the algorithm or analyzing the algorithm’s performance. We have also implemen...

A new facility has been built at the University of Michigan to study shear coaxial combusting gas-gas injection in a rocket combustion chamber. This facility, capable of chamber pressures of 10 atmospheres, is used to obtain a better understanding of the complex fluid dynamics and combustion processes found in rocket combustion chambers and to provide data to assess NASA’s computational fluid d...

Several requirements visualization techniques have been developed together with tools that support the techniques. This paper focuses on visualization techniques developed for requirements representation. These techniques are used to transform the written and verbal requirements into visual representations. Most of the existing techniques use graphics for visual representation. This paper revie...

Medical image collections contain a wealth of information which can assist radiologists and medical experts in diagnosis and disease detection for making well-informed decisions. However, this objective can only be realized if efficient access is provided to semantically relevant cases from the ever-growing medical image repositories. In this paper, we present an efficient method for representi...

The geometry of eye rotations necessitates an internal reference frame transformation between retinocentric visual codes and headcentric displacement commands for saccades. Here, we ask if this eye position-dependent transformation is bypassed in `express saccadesa or degraded in `memory saccadesa, perhaps to favor a more direct visuomotor transformation. The answer to both was no: quanti"catio...

In this paper we present a framework for tracking nonrigid facial landmarks by combining various visual cues at multiple levels of detail. Using a probabilistic framework consisting of a hierarchy of particle filters, we are able to track individual facial landmarks using multiple visual cues at the local level, as well as tracking results at more coarse level of detail. This allows for the fus...

The priming of patterns was examined in normal control subjects (NCS) and in the amnesic patient H.M., whose anterograde amnesia followed bilateral medial temporal-lobe excision 33 years earlier. Despite H.M.'s impaired recognition of the patterns, he demonstrated a pattern priming effect equivalent in magnitude to that of the NCS. The results demonstrated that intact priming with novel, nonver...

People spontaneously integrate the features of visual events into episodic structures that are reactivated if their ingredients match aspects of the current input. Feature integration has been attributed to either the detection of feature conjunctions or the ad hoc binding of feature codes (e.g., by neural synchronization). We report evidence suggesting that both kinds of integration mechanisms...

This paper describes the origins and history of multiple resource theory in accounting for di€ erences in dual task interference. One particular application of the theory, the 4-dimensional multiple resources model, is described in detail, positing that there will be greater interference between two tasks to the extent that they share stages (perceptual/cognitive vs response) sensory modalities...
