In this paper we present an approach that enables visually impaired people to explore multivariate data through scatter plots. Our approach combines Tangible Active Objects (TAOs) [1] and Interactive Sonification [2] into a non-visual multi-modal data exploration interface and thereby translates the visual experience of scatter plots into the audio-haptic domain. Our system and the developed so...

A theoretical method is presented that allows identification of optimal x-ray imaging geometry, considering the effects of x-ray source distribution, imaging task, x-ray scatter, and imager detective quantum efficiency (DQE). Each of these factors is incorporated into the ICRU-recommended figure of merit for image quality, the detectability index, which is maximized to determine the optimal sys...

X-ray Mammography examinations are highly affected by scattered radiation, as it degrades the quality of the image and complicates the diagnosis process. Anti-scatter grids are currently used in planar mammography examinations as the standard physical scattering reduction technique. This method has been found to be inefficient, as it increases the dose delivered to the patient, does not remove ...

Many animals use cues for small-scale navigation, including beacons, landmarks, compasses and geometric properties. Scatter-hoarding animals are a unique system to study small-scale navigation. They have to remember and relocate many individual spatial locations, be fairly accurate in their searching and have to remember these locations for long stretches of time. In this article, we review wha...

Flexible manufacturing system (FMS) scheduling is one of the most trusted and complicated task in machine scheduling. It is strongly Non polynomial complete combinatorial problem. FMS is agile and flexible which is well suited for simultaneous production of a wide variety of product mix in low volumes. Meta-heuristic approaches such as genetic algorithm, simulated annealing etc. are widely appl...

Nuisance Attribute Projection (NAP) provides an effective method of removing the unwanted session variability in a Support Vector Machine (SVM) based speaker recognition system by removing the principal components of this variability. There is no guarantee with the methods proposed, however, that desired speaker variability is retained. This paper investigates the possibility of training NAP di...

BACKGROUND Conventional diagnosis and identification of bacteria requires shipment of samples to a laboratory for genetic and biochemical analysis. This process can take days and imposes significant delay to action in situations where timely intervention can save lives and reduce associated costs. To enable faster response to an outbreak, a low-cost, small-footprint, portable microbial-identifi...

We present the first demonstration, to our knowledge, of a label-free flow cytometer for the analysis of biological specimens using multiplex coherent anti-Stokes Raman scattering (MCARS) and elastic scatter measurements. The MCARS system probes the Raman vibrational energy levels and the elastic scatter provides morphological information. We demonstrate these capabilities by probing a culture ...
