Power dispatching plays quite an important role in power grid operation in terms of safety and stability. Structured data has been well managed in the real-time power dispatching and controlling system. However, the management of unstructured data such as text data has not received enough attention. In this paper, we accomplish an application of auxiliary operation of power dispatching by doing semantic analysis on operation procedures, which belong to an important category of power dispatching text data for fault disposal. The method that we proposed in our application is achieved based on Natural Language Processing (NLP) technologies. Our contributions are mainly two-fold: 1) we accurately extract key information from text data through our proposed method, and 2) we help power dispatching operators reduce their work and improve efficiency by providing auxiliary operation advice. © 2020 IEEE.

Arterial stiffness is an effective parameter for monitoring sub-clinical arterial stiffness, and can tell effectively the cardioArterial health condition of human body. Elastic expansion coefficient of blood vessel (named as ETK) denotes the degree of arterial elastic expansion during systolic ejection, usually used to calculate other cardiovascular parameters as the intermediate variable. A new method is proposed to estimate directly the arteriosclerotic degree with ETK, and a non-invasive monitor for blood pressure and arterial stiffness is developed. Clinical experiment results show that the correlation coefficient between ETK and results of clinical ultrasound system is 0.76, which proves the validity of the method. © 2011 IEEE.

This paper provides a comprehensive survey of robotic autonomous grasping techniques. We summarize three key tasks: grasp detection, affordance detection, and model migration. Grasp detection determines the graspable area and grasping posture of the manipulator, so that the robot can successfully perform the grasps. The grasp detection methods based on deep learning are divided into 3DoF grasp and 6DoF grasp. The object affordances based grasping methods can further improve the robot's understanding of objects and environment, thereby improving the robot's intelligence and autonomy. Methods for object affordances detection are classified as learning-based, knowledge-based, and simulation-based. Model migration means that when the grasping model is migrated to other scenes where lightness and background changes, only little or no lab.l data is required, so that the grasping model can be used in the target scene quickly and efficiently. This paper focuses on domain adaptation (DA) methods in model migration. © 2021 IEEE.

This paper is concerned with the problem of robust controller design for electro-hydraulic servo systems driven by double-rod hydraulic actuators. Firstly, by introducing a linear varying parameter, an electro hydraulic servo system is described as a linear parameter varying(LPV) model. Secondly, based on this LPV model and a parameter-dependent Lyapunov approach, two parameter-dependent controllers are established for the stabilization and tracking problems, respectively. The obtained controllers are simple and their gains can vary with the parameter measured online. Finally, the numerical simulations demonstrate the satisfactory performance of the proposed controllers. © 2010 IEEE.

The effects of signal modality (visual and auditory), hand condition (crossed and uncrossed), and head orientation (upright, right-90, left-90, and left back) on response performance were e xamined in this study. The results showed all the factors significantly affected the reaction time of participants and there was an interaction effect between signal modality and head orientation. Responses for visual signals were significantly faster than those for auditory signals, and responses made with uncrossed hand were superior to those with crossed hand. On head orientation, upright orientation produced the fastest reaction time, while reaction time for head rotated 90° right (right-90) was significantly faster than that for head rotated 90° left (left-90) and rotated left backward (left back). Regarding the significant interaction effect between signal modality and head orientation, processing time for visual signals was always faster than that for auditory signals. Such modality superiority increased to a larger extent under the left 90 and left back head orientations. The findings in this experiment provide some practical ergonomics recommendations for improving control console design in terms of signal-response layout, stimulus-hand arrangement, head orientation, and methods of presenting visual and auditory signals.

The Proportional - Integral - Derivative (PID) controllers are one of the most popular controllers used in industry because of their remarkable effectiveness, simplicity of implementation and broad applicability. PID tuning is the key issue in the design of PID controllers and most of the tuning processes are implemented manually resulting in difficulty and time consuming. To enhance the capabilities of traditional PID parameters tuning techniques, modern heuristics approaches, such as Genetic Algorithm (GA) and Particle Swarm Optimization (PSO), are employed recent years. In this paper, a novel tuning method based on Fruit Fly Optimization Algorithm (FOA) is proposed to optimize PID controller parameters. Each fruit fly's position represents a candidate solution for PID parameters. When the fruit fly swarm flies towards one location, it is treated as the evolution of each iterative swarm. After hundreds of iteration, the tuning results - the best PID controller parameters can be obtained. The main advantages of the proposed method include ease of implementation, stable convergence characteristic, large searching range, ease of transformation of such concept into program code and ease of understanding. Simulation results demonstrate that the FOA-Based optimized PID (FOA - PID) controller is with the capability of providing satisfactory closed - loop performance. © 2012 IEEE.

Budget planning for coupled campaigns in search auctions

Budget-related decisions in search auctions are recognized as a structured decision problem, rather than a simple constraint. Budget planning over several coupled campaigns remains a challenging but utterly important task in search advertisements. In this paper, we propose a multi-campaign budget plan- ning approach using optimal control techniques, with consideration of the substitute relationship between advertising campaigns. A measure of coupled relationships between campaigns is presented, e.g., the over- lapping degree (O) in terms of campaign contents, promotional periods and target regions. We also discuss some desirable properties of our model and possible solutions. Furthermore, computational experiments are conducted to evaluate our model and identified properties, with real-world data collected from logs and reports of practical campaigns. Experimental results show that, (a) coupled campaigns with higher over- lapping degrees can reduce the optimal budget level and the optimal revenue, and also arrive the budgeting cap earlier;(b) The advertising effort could be seriously weakened when ignoring the overlapping degree between campaigns.

Under the condition of multi-microgrids system, due to the location dispersion of microgrids, and the different characteristics of distributed generations and loads, the size of sampling in a reliability assessment algorithm is always huge, which influences computational efficiency. In this paper, based on the operation characteristics of a multi-microgrid system, a reliability evaluation algorithm based on the parallel computing algorithm of the multi-microgrid system is proposed. The algorithm can sample the operating state of each microgrid at the same time and consider the interaction between the various microgrids in a multi-microgrids system. The algorithm can significantly improve the calculation speed of the reliability assessment algorithm of the multi-microgrid system, which is of great significance to the reliability evaluation of the multi-microgrid system in the region. © 2017 IEEE.
