This proposal aims to continue the preliminary experiments using SPPS, which demonstrated the feasibility of preforming XANES experiments on the femtosecond time scale. It also has the potential to provide a shot-by-shot measurement of the beam spectral profile. The instrument consists of a simple dispersive spectrometer coupled to an integrating position-sensitive detector. Experiments at NSLS...

We consider a group of mobile robotic agents, identical and indistinguishable, having no memory (oblivious) and no common frame of reference (neither absolute location nor a common orientation). Furthermore, these agents are assumed to posses only rudimentary sensing and computational capabilities (limited visibility and basic geometric sorting). We prove that, such robots, implementing a ”Chas...

Face recognition is one of the most socially accepted forms of biometric recognition. The recent availability of very accurate and efficient face recognition algorithms leaves the vulnerability to presentation attacks as the major challenge to face recognition solutions. Previous works have shown high preforming presentation attack detection PAD solutions under controlled evaluation scenarios. ...

This paper reports a comparative experimental evaluation of proportional derivative and adaptive modelbased control for underwater vehicles. To the best of the authors’ knowledge, this is the first such evaluation of modelbased adaptive tracking control for underwater vehicles during simultaneous dynamic motion in all 6 degrees-of-freedom. This experimental evaluation revealed the presence of u...

A finite element method is presented for predicting the mechanical performance of discontinuous fiber mesostructures typically produced by directed carbon fiber preforming. High-filament count bundles are modeled using beam elements to enable large representative volume elements to be studied. The beams are attached to a regular grid of 2D continuum elements, which represent the matrix material...

As part of the ongoing effort of designing secure DCOP algorithms, we propose P-MAX-SUM, the first private algorithm that is based on MAX-SUM. The proposed algorithm has multiple agents preforming the role of each node in the factor graph, on which the MAX-SUM algorithm operates. P-MAXSUM preserves three types of privacy: topology privacy, constraint privacy, and assignment/decision privacy. By...

The increasing complexity, heterogeneity, and rapid evolution of modern computer architectures present obstacles for achieving high performance of scientific codes on different machines. Empirical performance tuning is a viable approach to obtain highperforming code variants based on their measured performance on the target machine. In previous work, we formulated the search for the best code v...

Today, automobile and aircraft industry uses more and more robust and light-weight parts made of carbon fibres. To achieve high structural properties the carbon fibre mats are stitched in the preforming process using a sewing robot. The goal of this work is to develop an edge tracking system that continuously follows the seams. To work with the black and reflective carbon fibres a laser-scan se...

Utilizing the surface plasmon resonance effect in gold nanoparticles enables their use as contrast agents in a variety of applications for compound cellular imaging. However, most techniques suffer from poor signal to noise ratio (SNR) statistics due to high shot noise that is associated with low photon count in addition to high background noise. We demonstrate an effective way to improve the S...
