Generation of feasible and optimal reference trajectories is crucial in tracking Nonlinear Model Predictive control. Especially, for stability and optimality in presence of a time varying parameter, adaptation of the tracking trajectory has to be implemented. General approaches are real-time generation of trajectories or switching between a discrete set of precomputed trajectories. In order to circumvent the operational efforts of these methods for a special type of dynamical systems, we propose time warping as an alternative approach. This algorithm implements online generation of tracking trajectories by warping a single precomputed reference. In detail, warpable systems, feasibility and optimality of trajectories and the controller implementation are discussed. Finally, as an application example, simulation results of a tethered kite system for airborne wind energy generation are presented. © 2017

The development of the autonomous driving system is still a hot topic. Especially in the area of the interaction between the autonomous driving system and road crossing pedestrians. Recognizing the pedestrian crossing intention is one of the crucial topics for the smart autonomous driving system. The autonomous driving system must be safe enough for both its user and pedestrian. Many research, approach, and method has been developed to detect or predict pedestrian crossing intention. But unfortunately, many previous works predict the pedestrian crossing intention that already does cross the road. There is still few research about how to predict early pedestrian crossing intention. Usually when they want to cross the road or before they do cross the road, the pedestrian gives unique gestures like looking at the incoming vehicle. Thus, an early warning pedestrian crossing intention system has been developed using a different approach, by its head gesture. The pedestrian crossing intention could be predicted by classifying its head pose angle. Experiment show very well that the proposed method able to predict early pedestrian crossing intention by its head gesture and give an early warning sign to the autonomous driving system with the accuracy of the classification 97.2%. We believe our work could bring benefits to the autonomous driving system to increase the safeties of its system. © 2021 IEEE.

As the voltage and current waveforms are deformed due to transient during faults, their pattern changes according to the type of fault. The Artificial Neural Network (ANN) can then be used for fault detection due to its distinguished behavior in pattern recognition. In order to minimize the structure and timing of the ANN, preprocessing of the voltage and current waveforms was done. The data delivered from a simulated power system using PSCAD (EMTP with cad system) was used for training and testing the ANN. An experimental setup, consists of a 3 phase power supply module and transmission line module, is utilized. A set of signal conditioning circuits is designed and implemented in order to transfer data to a PC which is used as an on-line relay for fault detection. This is done via a data acquisition card (CIO-DAS1602/12). The Matlab program captures and processes real data for training the ANN. Applying different types of faults for testing the system, right tripping action was taken and the type of fault was correctly identified. The suggested artificial neural network algorithm has been found simple and effective hence could be implemented in practical application.

The objective of this paper is to put forward an intelligent system to assist and enable potential users who intend to make investment on Micro Electro Mechanical System (MEMS) products. The system functions as a decision support system to help users the potentiality of investment in MEMS industry by predicting future sales and profitability based on past knowledge. In this paper work Fuzzy Logic system (FLs) is proposed, as it is conveniently adaptable to solve such problems. Among the many factors that are important for predicting MEMS industry potential, are sales, price, profit, earning, P/E ratio, PEG, P/S ratio. Some of these factors may be related, but some act independently. These factors are combined together into a finalize result. Data Fusion is the process of combining multiple economic factors in order to produce information of tactical value to the user. Briefly, in this project, the behaviour of an intelligent system is simulated by the Fuzzy Logic toolbox. In fact, the output variable and valuation scale is 'investment'. It is fuzzy variable and compared this output rate with actuality.

Consensus based control of multi-agent systems has a widespread applications in many fields. For example, autonomous computing, wireless sensor networks and robotics etc. It has several interesting results for clustering in data mining and Economics dispatch problem in distributed electric generation. A lot of theoretical analysis have been applied for such problems using consensus approach but still a practical approach to consensus based control of multi-agent systems is needed. This paper presents theoretical as well as practical systems for smart grid using consensus algorithm. Economic dispatch problem which is the major issue in smart grid is resolved through distributed consensus approach. For experimental purpose, a framework of Arduino IDE is selected for analysis, communication and simulation. Each Arduino board is an intelligent and autonomous agent that is in communication with all its neighbour's nodes for adapting changes in demand and generation of power in Smart grid. Moreover, a dynamically changing behaviour of the systems is also in focus of this paper. © 2018 IEEE.

The emerging trend of distributed and renewable energy sources encourages energy trading in the electricity market. Various forms of energy markets are evolving for successful energy trading. The local energy market is one of them in which various participants are actively coordinating for optimal utilization of power. Such type of local energy markets provides individual prosumers to trade their surplus energy in the neighbourhood in peer-to-peer topology. The complexity of such type of local energy market is increasing in terms of structure, control, coordination, and cost estimation. For the cooperative behaviour of the local energy markets, a dual auction coordination control scheme is important to encourage more prosumers for energy trading. We proposed a novel scheme that performs dual auctions for prosumers in a decentralized fashion. We assessed dual auction matching by coordinating prosumers and consumers to sell and purchase energy in the local energy market. The aggregator performed balancing in the proposed dual auction scheme as an autonomous entity. The results were simulated in MATLAB and JADE for the complex prosumer peer-to-peer network. Our proposed scheme shows each peer dual auction matching improves from 0.95 to 2.03 for optimal hierarchal energy trading in energy markets. For peer participation, the participation ratio increased from 0.684 to 1.74 and optimal aggregator coordination from 9.18% to 19% in the local energy markets. © 2023 IEEE.

The availability of large historical corpora, such as Google Books Ngram, makes it possible to extract various meta information about the evolution of human languages. Together with advances in machine learning techniques, researchers recently use the huge corpora to track cultural and linguistic shifts in words and terms over time. In this paper, we develop a new approach to quantitatively recognize semantic changes of words during the period between 1800 and 1990. We use the state-of-the-art FastText approach to construct word embedding for Google Books Ngram corpus for the decades within the time period 1800-1990. We use a time series analysis to identify words that have a statistically significant change in the period between 1900 and 1990. We conduct a performance evaluation study to compare our approach against related work, we show that our system is more robust against morphological language variations.

In-field test of electronic devices is becoming increasingly important due to the wide adoption of electronic systems in safety-critical applications. Hence, it is crucial to devise and deploy effective solutions supporting the test during the operational phase of all the components of an electronic system, including the memory modules embedded in a SoC. Some key aspects include the possible reuse of HW infrastructures introduced for end-of-manufacturing test, the need for limited intrusiveness with respect to the application, and the achievable defect coverage. The paper discusses the main challenges in this area and possible solutions, as well as future trends. © 2017 IEEE.

In today's world, large volumes of medical data are being continuously generated, but their value is severely undermined by our inability to translate them into knowledge and, ultimately, actions. Data mining techniques allow the extraction of previously unknown interesting patterns from large datasets, but their complexity limits their practical diffusion. Data-driven analysis is a multi-step process, in which health care professionals define analysis goals and assess extracted knowledge, while computer scientists tackle the non trivial task of driving the miner system analysis activity. This paper addresses the mining activity from a different perspective. We believe that mining systems should be able to devise which knowledge could be most interesting to users and extract actionable knowledge from large medical datasets, with minimal user intervention. More specifically, mining systems should be capable of (i) devising viable end-goals for a specific dataset (i.e., that yield actionable knowledge to the user and are feasible given the dataset characteristics and size), based on the expertise acquired during the analysis of previous datasets, and (ii) extracting a manageable set of knowledge. Automated data analysis should fuel the next generation of medical mining systems, thus enabling users to automatically mine massive data repositories. © 2016 IEEE.
