This paper formulates and proposes solutions to the problem of estimating/reconstructing the absolute (not simply modulo-2pi) phase of a complex random field from noisy observations of its real and imaginary parts. This problem is representative of a class of important imaging techniques such as interferometric synthetic aperture radar, optical interferometry, magnetic resonance imaging, and di...

We consider the problem of de novo DNA sequencing from shot gun data, wherein an underlying (unknown) DNA sequence is to be reconstructed from several short substrings of the sequence. We propose a de novo assembly algorithm which requires only the minimum amount of data and is efficient with respect to space and computation. We design the algorithm from an information theoretic perspective of ...

The union of two different dental sprouts which can happen in any phase of dental development is commonly called fusion. This developmental anomaly may cause clinical problems including esthetic impairment, which are mainly treated by endodontic and surgical treatments. There are a few reports of conservative not invasive treatment of fused incisors teeth through restorative or prosthetic techn...

MPEG-4 object oriented video codec implementations are rapidly emerging as a solution to compress audio-video information in an efficient way, suitable for narrowband applications. A different view is proposed in this paper: several images in a video sequence result very close to each other. Each image of the sequence can be seen as a vector in a hyperspace and the whole video can be considered...

Methods for carrying out coherent X-ray scattering experiments are reviewed. The brilliance of the available synchrotron sources, the characteristics of the existing optics, the various ways of obtaining a beam of controlled coherence properties and the detectors used are summarized. Applications in the study of the dynamics of speckle patterns are described. In the case of soft condensed matte...

Verifiable secret sharing schemes are important in cloud computing environments. Thus a key can be distributed over many servers by threshold secret sharing mechanism. The key is then reconstructed when needed. Secret sharing has also been suggested for sensor networks where the links are liable to be tapped by sending the data in shares which makes the task of the eavesdropper harder. The secu...

The task of syntactic pattern recognition has aroused the interest of researchers for several decades. The power of the syntactic approach comes from its capability in exploiting the sequential characteristics of the data. In this work, we propose a new method for syntactic recognition of handwritten characters. The main strengths of our method are its low run-time and space complexity. In the ...

Ridges in the state space distribution of finite-time Lyapunov exponents can be used to locate dynamical boundaries. We describe a method for obtaining dynamical boundaries using only trajectories reconstructed from time series, expanding on the current approach which requires a vector field in the phase space. We analyze problems in musculoskeletal biomechanics, considered as exemplars of a cl...
