TL;DR: Results support many of the criticisms of work-family research and suggest that scholars publishing WF research in industrial-organizational psychology and organizational behavior journals could make greater use of longitudinal and experimental research designs, gather more multisource data, and move beyond the individual level of analysis.
Abstract: A methodological review was conducted of work-family (WF) research published in industrial-organizational psychology and organizational behavior journals over a period of 24 years (1980-2003). Content analysis was conducted on 225 individual studies published in 210 articles to categorize methodological features, including the research design, sources of data used, data analysis techniques, reliability and validity of measures used, and sociodemographic characteristics of the samples. Results support many of the criticisms of WF research and suggest that scholars publishing WF research in industrial-organizational psychology and organizational behavior journals could make greater use of longitudinal and experimental research designs, gather more multisource data, and move beyond the individual level of analysis. Adopting more diverse conceptualizations of family, including a greater proportion of racial and ethnic minorities, and studying workers in occupations other than managerial or professional positions also appear warranted. Finally, methodological trends varied across specific WF content areas, which suggests that distinct methodologies might be useful to advance knowledge of specific WF topics.

TL;DR: This article defines WSNs with MEs and provides a comprehensive taxonomy of their architectures, based on the role of the MEs, and provides an extensive survey of the related literature.
Abstract: Wireless sensor networks (WSNs) have emerged as an effective solution for a wide range of applications. Most of the traditional WSN architectures consist of static nodes which are densely deployed over a sensing area. Recently, several WSN architectures based on mobile elements (MEs) have been proposed. Most of them exploit mobility to address the problem of data collection in WSNs. In this article we first define WSNs with MEs and provide a comprehensive taxonomy of their architectures, based on the role of the MEs. Then we present an overview of the data collection process in such a scenario, and identify the corresponding issues and challenges. On the basis of these issues, we provide an extensive survey of the related literature. Finally, we compare the underlying approaches and solutions, with hints to open problems and future research directions.

TL;DR: Q-learning and the integral RL algorithm as core algorithms for discrete time (DT) and continuous-time (CT) systems, respectively are discussed, and a new direction of off-policy RL for both CT and DT systems is discussed.
Abstract: This paper reviews the current state of the art on reinforcement learning (RL)-based feedback control solutions to optimal regulation and tracking of single and multiagent systems. Existing RL solutions to both optimal $\mathcal {H}_{2}$ and $\mathcal {H}_\infty $ control problems, as well as graphical games, will be reviewed. RL methods learn the solution to optimal control and game problems online and using measured data along the system trajectories. We discuss Q-learning and the integral RL algorithm as core algorithms for discrete-time (DT) and continuous-time (CT) systems, respectively. Moreover, we discuss a new direction of off-policy RL for both CT and DT systems. Finally, we review several applications.

19 Jun 2017TL;DR: A Long Short-Term Memory (LSTM) approach for RUL estimation is proposed, which can make full use of the sensor sequence information and expose hidden patterns within sensor data with multiple operating conditions, fault and degradation models.
Abstract: Remaining Useful Life (RUL) of a component or a system is defined as the length from the current time to the end of the useful life. Accurate RUL estimation plays a critical role in Prognostics and Health Management(PHM). Data driven approaches for RUL estimation use sensor data and operational data to estimate RUL. Traditional regression based approaches and recent Convolutional Neural Network (CNN) approach use features created from sliding windows to build models. However, sequence information is not fully considered in these approaches. Sequence learning models such as Hidden Markov Models (HMMs) and Recurrent Neural Networks (RNNs) have flaws when modeling sequence information. HMMs are limited to discrete hidden states and are known to have issues when modeling long-term dependencies in the data. RNNs also have issues with long-term dependencies. In this work, we propose a Long Short-Term Memory (LSTM) approach for RUL estimation, which can make full use of the sensor sequence information and expose hidden patterns within sensor data with multiple operating conditions, fault and degradation models. Extensive experiments using three widely adopted Prognostics and Health Management data sets show that LSTM for RUL estimation significantly outperforms traditional approaches for RUL estimation as well as Convolutional Neural Network (CNN).
