Traditional passive radar systems with a noisy reference signal use the cross-correlation statistic for detection. However, owing to the composite nature of this hypothesis testing problem, no claims can be made about the optimality of this detector. Therefore, exploiting the low-rank structure of most passive radar illuminators, we recently proposed singular value decomposition based detectors that outperform the CC detector. In this paper, we derive the generalized likelihood ratio tests for this signal model and compare with our proposed SVD based detectors. We demonstrate the near CFAR behavior (highly desirable) of our SVD detectors. We show that on the other hand, the GLRT detectors have a varying probability of false alarm with changing reference channel characteristics making it impractical to use them in a passive radar system. © 2016 IEEE.

The sheer volume of unstructured multimedia data (e.g., texts, images, videos) posted on the Web during events of general interest is overwhelming and difficult to distill if seeking information relevant to a particular concern. We have developed a comprehensive system that searches, identifies, organizes and summarizes complex events from multiple data modalities. It also recommends events related to the user's ongoing search based on previously selected attribute values and dimensions of events being viewed. In this paper we briefly present the algorithms of each component and demonstrate the system's capabilities. © NAACL-HLT 2016 - 2016 Conference of the North American Chapter of the Association for Computational Linguistics: Human Language Technologies, Proceedings of the Demonstrations Session.

In this research, we demonstrate a novel operating method of spiral microfluidics to enrich rarecell from the patient-derived sample, even if unit single pass separation step cannot provide adequate separation resolution. By feeding the output stream of the separation back to original sample, and running continuously with high flow processing rate, one can achieve high preconcentration, recovery and purity of target cells. We demonstrated this method in two clinically relevant cell separation challenges;sputum and blood separation.

This paper introduces a cognitive architecture for a humanoid robot to engage in a proactive, mixed-initiative exploration and manipulation of its environment, where the initiative can originate from both the human and the robot. The framework, based on a biologically-grounded theory of the brain and mind, integrates a reactive interaction engine, a number of state-of-the art perceptual and motor learning algorithms, as well as planning abilities and an autobiographical memory. The architecture as a whole drives the robot behavior to solve the symbol grounding problem, acquire language capabilities, execute goal-oriented behavior, and express a verbal narrative of its own experience in the world. We validate our approach in human-robot interaction experiments with the iCub humanoid robot, showing that the proposed cognitive architecture can be applied in real time within a realistic scenario and that it can be used with naive users.

Optimal Threshold Policy for Sequential Weapon Target Assignment

We investigate a variant of the classical Weapon Target Assignment (WTA) problem, wherein N targets are sequentially visited by a bomber carrying M homogenous weapons. We are interested in the optimal assignment of weapons to targets. A weapon launched by the bomber destroys the jthtarget with probability pjand upon successful elimination, the bomber earns a positive reward rj. There is feedback in that the bomber, upon deploying a weapon, is notified whether or not it successfully destroyed the target. Whereupon, it decides whether to move on to the next target or allocate an additional weapon to the current target. We provide a tractable solution method for computing the optimal closed loop control policy that results in maximal expected total reward. Moreover, we show that a thresholding policy is optimal, wherein a weapon from an inventory of k weapons is dropped on the jthtarget iff k exceeds a stage dependent threshold value, κ(j). © 2016

Distributed clock synchronization with intermittent communication is addressed in this paper. An event-triggered control and communication approach is presented in order to determine in a decentralized way the time instants at which each agent transmits information. The decentralized event-triggered synchronization of clocks is formulated as a single integrator consensus problem in the particular case and as double integrator consensus problem in the general case. The main contribution of this paper, besides the implementation of event-triggered mechanisms, is the feature that the virtual clocks are continuous. This is an important property because of the processes associated to each local clock, where missing deadlines or performing time dependent tasks more than once needs to be avoided.

We predict the instability of plasma waves excited by a DC current in the field-effect transistors (FETs) with a partly gated channel. The excitation of plasma waves is due to amplified reflection from the boundary of the gated and ungated regions. The boundary also supports the turbulent edge modes whose increment strongly depends on the ratio of the carrier densities in the two FET regions. © 2016 World Scientific Publishing Company.
