This paper presents a method of the adequacy of voltage transgression in a real power distribution network. This method aims to adjust the voltage levels through the optimization of the insertion position of Photovoltaic (PV) Distributed Generation (DG) in the network. The real feeder was simulated using Open Distribution System Simulator (OpenDSS) software. The optimization used a deterministic method to find the optimized insertion sites of the Photovoltaic DG. Through the optimized insertions, a network with a larger number of nodes with adequate voltage was obtained. © 2017 IEEE.

We consider a distributed multi-agent network system where the goal is to minimize an objective function that can be written as the sum of component functions, each of which is known (with stochastic errors) to a specific network agent. We propose an asynchronous algorithm that is motivated by a random gossip scheme where each agent has a local Poisson clock. At each tick of its local clock, the agent averages its estimate with a randomly chosen neighbor and adjusts the average using the gradient of its local function that is computed with stochastic errors. We investigate the convergence properties of the algorithm for two different classes of functions: differentiable but not necessarily convex and convex but not necessarily differentiable. ©2009 IEEE.

There are multiple ways to control a robotic system. Most of them require the users to have prior knowledge about robots or get trained before using them. Natural language based control attracts increasing attention due to its versatility and less requirements for users. Since natural language instructions from users cannot be understood by the robots directly, the linguistic input has to be processed into a formal representation which captures the task specification and removes the ambiguity inherent in natural language. For most of existing natural language controlled robotic system, they assume the given language instructions are already in correct orders. However, it is very likely for untrained users to give commands in a mixed order based on their direct observation and intuitive thinking. Simply following the order of the commands can lead to failures of tasks. To provide a remedy for the problem, we propose a novel framework named dependency relation matrix （DRM） to model and organize the semantic information extracted from language input, in order to figure out an executable sequence of subtasks for later execution. In addition, the proposed approach projects abstract language input and detailed sensory information into the same space, and uses the difference between the goal specification and temporal status of the task under implementation to monitor the progress of task execution. In this paper, we describe the DRM framework in detail, and illustrate the utility of this approach with experiment results.

Agent Transformation of Bayesian Games

IEEE Transactions on Automatic Control 2022年第11期67卷 5793-5808页

A new transformation that converts a Bayesian game to a so-called ex-ante agent game (a normal-form game) is proposed. Differently from the existing transformation proposed by R. Selten that changes a Bayesian game to an interim agent game (also a pure normal-form game), we prove that the new transformation preserves potentiality. In addition, there is a nonpotential Bayesian game whose ex-ante agent game is potential. We also prove that there is one-to-one correspondence between pure Bayesian Nash equilibria (BNE) of Bayesian games (if one exists) and pure Nash equilibria (NE) of the resulting ex-ante agent games. Then, we provide a sufficient and necessary condition for a Bayesian game to have an ex-ante agent potential game. By using these results, one can transform pure BNE seeking in Bayesian games to pure NE seeking in their ex-ante agent games [by using the potential functions of the ex-ante agent games (if one exists)], where previously pure BNE seeking in Bayesian games by using potential functions can only be done in Bayesian potential games (BPGs). Particularly, we prove for two-player games that BPGs are exactly the Bayesian games having ex-ante agent potential games. Furthermore, by using the semi-tensor product of matrices, a potential equation for finite Bayesian games is developed. Based on the potential equation, algorithms for verifying potentiality and for searching pure BNE in finite Bayesian games are designed. Finally, the results are applied to a routing problem with incomplete information. © 1963-2012 IEEE.

Nearly 80% of worldwide trade (over US $620 billion) is carried by marine transport. Unfortunately, manually identifying, tracking, and monitoring containers involves a great many logistical problems. The security of container transportation has also become an issue of critical importance, with regard to theft, tracking, tracing, and national security. This paper describes the passive radio frequency identification (RFID) electronic seal (e-seal) monitoring system that was implemented using existing low-cost passive RFID e-seals devices to replace the manual escorts. The system successfully overcame the harsh outdoor environment of Kaohsiung Port, including resistance to high temperature, high salinity, humidity, and typhoons. The system comprises a reader, an e-seal (tag), and an antenna, and its optimal installation architecture is being disclosed in this paper. The reading rate not only has been maintained at levels above 97.4% when a container truck travel passes an RFID reader at a speed of up to 60 kilometers per hour in 0.2 seconds, the system has also maintained normal operation 24 hours a day, year round. The system has moved beyond the testing phase or small-scale pilot project bringing RFID technology to practical operations of large-scale logistics systems. The architecture, procedures, methodologies, and experience involved in the development of this system, deserve consideration as a guide for the future introduction of RFID systems, and can relieve operators from the expensive, time-consuming trial and error involved in the introduction of passive RFID e-seal systems in the container transport industry.

This paper presents a methodology of placement of multiple distributed-generation photovoltaic (DGPV) for minimization of voltage transgression in a power distribution real network. Currently, there are several methodologies for placement of distributed generators, still being an open question for the scientific community. The goal of this paper is to optimize siting, sizing and amount of multiple DGPV. The evaluation function used corresponds to the sum of the voltage transgressions in each phase, in a constrained optimization. The genetic algorithm was used in the optimization, besides a hybridized method based on genetic algorithm and Nelder-Mead method. At the end of the simulations, a reduction in the value of the evaluation function was obtained, which resulted a significant increase in the number of electrical nodes with adequate voltage levels. © 2019 IEEE.

Do algorithms and barriers for sparse principal component analysis extend to other structured settings?

We study a principal component analysis problem under the spiked Wishart model in which the structure in the signal is captured by a class of union-of-subspace models. This general class includes vanilla sparse PCA as well as its variants with graph sparsity. With the goal of studying these problems under a unified statistical and computational lens, we establish fundamental limits that depend on the geometry of the problem instance, and show that a natural projected power method exhibits local convergence to the statistically near-optimal neighborhood of the solution. We complement these results with end-to-end analyses of two important special cases given by path and tree sparsity in a general basis, showing initialization methods and matching evidence of computational hardness. Overall, our results indicate that several of the phenomena observed for vanilla sparse PCA extend in a natural fashion to its structured counterparts. Copyright © 2023, The Authors.
