One of the DC motor is considered as a leader motor and it tracks its desired speed trajectory. The other DC motor is controlled through a leader-follower based optimal formation controller developed in this work. If the leader DC motor slows down or speeds up for some reason, the follower DC motor synchronize its speed according to the leader without having any knowledge about the desired trajectory. By doing so, the multiple DC motors will be able to work together in a synchronized manner. The simulation results are given at the end of the paper to verify our theoretical claims.","PeriodicalId":433166,"journal":{"name":"2018 4th International Conference on Optimization and Applications (ICOA)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123997658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These dynamic loads are the main factor that affects the accuracy of the High Speed Weigh in Motion System (HS-WIM), which are designed for measuring axle load of moving vehicles at normal speed. This paper introduces the algorithm of the Lagrange Polynomial Interpolation to reconstruct the axle load signal on a limited bandwidth and few simulation tests are completed as well. The reconstruction of the signal, performed from discrete samples, allows the estimation of the static axle load. The drawn conclusion of this study confirms, through the simulation tests, the efficiency of the studied algorithm, which is proven through the encouraging values of the evaluation indicators related to the signal reconstruction quality.","PeriodicalId":433166,"journal":{"name":"2018 4th International Conference on Optimization and Applications (ICOA)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126909015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

So, all parts needed for normal operation and maintenance must be readily available to ensure business flights. As there are business-aircrafts' spare parts which have lead times of up to three years, to ensure that the right parts are available at the right time in the right volume and at the right location, forecasts must be made of anticipated customer demand. The overestimated demand results in holding costs as storage, rent utilities and product obsolescence costs whereas underestimated demand leads to back order and stock out. The demand in business aircrafts industry is volatile so traditional forecasting methods are not efficient. This give rise of interest in data driven forecasting methods e.g. Bootstrap, Neural Network etc. have compared existing traditional and data driven methods and proposed an extension to Bootstrap through sliding window concept as best performing forecasting method. In this paper, optimization methodology for the sliding window bootstrap is proposed to improve forecasting accuracy. Results are validated using data from Dassault Falcon Business Jet.

The IIR filters are fundamental elements of digital signal processing, they can present a better performance compared to that of the FIR filters. However, the error surface of IIR filters is generally nonlinear and multimodal. Hence, global optimization techniques must be used. The Ant Colony algorithms form a class of proposed metaheuristics for solving difficult optimization problems. In this paper, tow variants of Ant Colony Optimization, namely, the Ant System and the Ant Colony System are proposed to deal with the optimal design of IIR filters.

Big Data real-time processing have received a growing attention especially with the expansion of data in volume and complexity. Big data is created every day, from the use of the Internet through social networks, mobile devices, connected objects, videos, blogs and others. In order to ensure a reliable and a fast real-time information processing, powerful tools are essential for the analysis and processing of Big Data. Standards MapReduce frameworks such as Hadoop MapReduce face some limitations for processing real-time data of various formats. In this paper, we highlight the implementation of the de-facto standard Hadoop MapReduce and also the implementation of the framework Apache Spark. Thereafter, we conduct experimental simulations to analyze a real-time data stream using Spark and Hadoop. To further enforce our contribution, we introduce a comparison of the two implementations in terms of architecture and performance with a discussion to feature the results of simulations. The paper discusses also the drawbacks of using Hadoop for real-time processing.","PeriodicalId":433166,"journal":{"name":"2018 4th International Conference on Optimization and Applications (ICOA)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134590247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
