We study a multiplayer stochastic differential game, where agents interact through their joint price impact on an asset that they trade to exploit common trading signal. In this context, we prove closed-loop Nash equilibrium exists if the parameter is small enough. Compared corresponding open-loop equilibrium, both agents' optimal rates and performance move towards central-planner solution, in ...

Oversampled pyramid decompositions have been successfully applied to scalable video coding. Quantization noise feedback at the encoder (\closed-loop coding") has several advantages compared to \open-loop coding" where noise feedback is not included. Finding optimal bit allocations for closed-loop coders is a complex task since the rate-distortion (R D) performance of one quantizer depends on th...

This paper studies the closed-loop system identification (ID) error when a dynamic integral controller is used. Pseudo-random binary sequence (PRBS) q-Markov covariance equivalent realization (Cover) is used to identify the closed-loop model, and the open-loop model is obtained based upon the identified closed-loop model. Accurate open-loop models were obtained using PRBS q-Markov Cover system ...

In this paper, we investigate the parameters affecting Total Harmonic Distortion (THD) and Power Supply Rejection Ratio (PSRR) in PWM Class D Amplifiers (CDAs) on the basis of linear models with feedback. From our mathematical analysis, we show that the THD of a PWM Class D amplifier with feedback can be improved by increasing the gain of the integrator through adding another amplifier at the o...

In this contribution we study the statistical properties of a number of closed-loop identiication methods and parameterizations. A focus will be on asymptotic variance expressions for these methods. By studying the asymptotic variance for the parameter vector estimates we show that indirect methods fail to give better accuracy than the direct method. Some new results for bias distribution in cl...

We present a system for large scale robotic learning from demonstration. We describe a set of software tools for enabling human-robot interaction over the internet and gathering the large datasets that such crowdsourcing makes possible. We show results in which humans teach a robot to navigate a maze over the Internet. Robots occupy a peculiar place in our culture. We have been building robots ...

Closed loop obstruction occurs when a segment of bowel is incarcerated at two contiguous points. The diagnosis is based on multiple transitional zones. The incarcerated loops appear in U or C form or present a radial layout around the location of the obstruction. It's very important to specify the type of obstruction because, in patients with simple bowel obstruction, a conservative approach is...
