In sharp contrast to this situation, however, there are fields like ecology where control methodologies have not been so successful in practice. This largely due to the poor quality of models that are available and the limited amount of reliable data that can be gathered. An emerging set of control techniques known collectively as data-driven control appears to be a natural candidate for control problems in such fields. The main objective of this paper is to describe one such algorithm based on recent advances in the modeling of nonlinear input-output systems in terms of Chen-Fliess series or Fliess operators. The idea is to combine a class of discrete-time Fliess operator approximators with a standard least-squares algorithm found in adaptive control to produce a time-varying input-output model that can be used to do predictive control. As an illustration, the method is applied to a predator-prey model in order to control the population level of the prey species.","PeriodicalId":374572,"journal":{"name":"2017 21st International Conference on System Theory, Control and Computing (ICSTCC)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128535490","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}

The proposed fractional system of commensurate order is derived from another fractional system of non commensurate order through an identification method based on the recursive least squares algorithm. The choice of the fractional system of commensurate order representation is due mainly to the ability to use this representation to implement the PEA using analogue circuits through rational function approximation of its irrational transfer function, to represent the PEA using a fractional order state space representation, to easily study the PEA's stability and to derive its closed form responses. The proposed PEA model has been validated in simulation and on an experimental set-up from Gipsa-lab.","PeriodicalId":374572,"journal":{"name":"2017 21st International Conference on System Theory, Control and Computing (ICSTCC)","volume":"139 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128838643","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}

The source code quality facilitates the maintenance and the evolution of the program. In the object-oriented paradigm, a modular system is easy to maintain thanks to its components with strong cohesion and weak or low coupling. Weak coupling is among the key factor to reduce the cost and the deadline of the system developing and maintaining. We propose to evaluate this factor since the design of system. In this paper, the proposed approach consists in the automatic detection of coupling type in the object-oriented design level. To do this, we have elaborated rules to detect the strongest coupling type. It belongs then to the designer to do redesign for a weak coupling code. As a result, the proposed strategy detects the types of coupling within each UML sequence diagram object at the design level. To validate our strategy, we conducted a case study. Then, the results obtained are adapted in a fuzzy architecture for validation. And finally, the output of the fuzzy architecture is a fuzzy membership function of total output coupling. The results show that our approach helps designers and software developers to obtain a better quality of software product.","PeriodicalId":374572,"journal":{"name":"2017 21st International Conference on System Theory, Control and Computing (ICSTCC)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125635442","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}

Globalization offers new ways of procuring the precursors of these substances (e.g. online) and helps cover the increasing production needs of clandestine laboratories. Hence, law enforcement authorities need new analytical instruments enabling an efficient and fast detection of these controlled substances for border control (customs) and police operations. We are presenting a chemometrical application designed to perform the automated recognition of ephedrines based on their vibrational absorptions.

In a phase, it is difficult to extract the full attitude knowledge of the satellite, however, it can be possible to determine the coarse attitude angular rate of the satellite using the difference of two successive magnetometer measurements. It is required to put the satellite attitude from the unknown random attitude to a predictable attitude. This filter was designed for an axially symmetric configuration with almost equal moments of inertia around all axes and diagonal matrix of inertia in previous literature. This paper presents another design for a micro satellite with different moments of inertia around all axes and non-zero off diagonal. The paper describes also the various steps to design the coarse attitude angular rate estimator for low earth satellite.

Web robots can be good (used for example by search engines) or bad (for bypassing security solutions, scraping, spamming or hacking), but usually all take up the internet bandwidth and can cause damage to businesses that rely on web traffic or content. Sorting human online traffic from bot activity isn't an easy task. The constantly evolving range of attacks, and the continuous optimization of bots, pose a new set of challenges. Our proposal is the first step for a larger automated solution that implies using the various intrusion detection system (IDS) methods and tools combined with mining algorithms. The final objective of the solution is the automated and effective detection of real bad bot threats for taking the appropriate security measures. The method proposes an automated flow from capturing the network traffic to the extraction of the input data to the mining algorithms (as the pre-processing step) and also an initial pattern detection and visualization with the scope of identifying potential threats generated by suspicious web crawlers. The first results are encouraging and represent the initial phase of identifying the potential threats from bad web robots.","PeriodicalId":374572,"journal":{"name":"2017 21st International Conference on System Theory, Control and Computing (ICSTCC)","volume":"256 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132503096","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}
