An internal clock-like process has been implicated in the control of rhythmic movements performed for short (250-2,000 ms) time scales. However, in the past decade, it has been claimed that a clock-like central timing mechanism is not required for smooth cyclical movements. The distinguishing characteristic delineating clock-like (event) from non-clock-like (emergent) timing is thought to be th...

This paper presents a method that automatically detects the location of the title block in scanned technical drawings. Numerous applications could benefit from such a tool. For example, it is useful to locate and zoom on the drawing title block, which can help in indexing technical drawings. As the title block is normally on the right-bottom corner of the drawing, it can also permit turning the...

This survey provides a description of algorithms to reorder visual matrices of tabular data and adjacency matrix of networks. The goal of this survey is to provide a comprehensive list of reordering algorithms published in different fields such as statistics, bioinformatics, or graph theory. While several of these algorithms are described in publications and others are available in software lib...

Bertin’s reorderable matrix (Bertin 1981, 1983, 2001) is a simple visualization method for exploring tabular data. The basic idea is to transform a multidimensional data set into a 2D interactive graphic. The graphical presentation of a data set contains rows and columns which can be permuted, allowing different views of the data set. The actual data values are replaced with symbols, say circle...

In life sciences, the importance of complex network visualization is ever increasing. Yet, existing approaches for the visualization of networks are general purpose techniques that are often not suited to support the specific needs of researchers in the life sciences, or to handle the large network sizes and specific network characteristics that are prevalent in the field. Examples for such net...

An earlier study (D. Koretz, 1997) found that Kentucky had been unusually successful in testing most students with disabilities, but it also found numerous signs of poor measurement, including differential item functioning (DIF) in mathematics, apparently excessive use of accommodations, and implausibly high mean scores for some groups of students with disabilities. This study used newer data t...

Conventional shape matching for engineering models primarily considers rigid shape similarity. They do not seek global shape similarity while considering large local deformations. However, engineering models created by some parametric-based design can involve large parametric changes. As a result, they do not share similarity in their global shape. Hence our goal is to develop shape representat...

In this paper we consider the problem of simultaneous drawing of two graphs. The goal is to produce aesthetically pleasing drawings for the two graphs by means of a heuristic algorithm and with human assistance. Our implementation uses the DiamondTouch table, a multiuser, touch-sensitive input device, to take advantage of direct physical interaction of several users working collaboratively. The...
