By the simulation we are going to develop a control box that controls also the mechanical power source (engine), the reactive power compensator, the breakers and the load too.","PeriodicalId":312683,"journal":{"name":"2015 IEEE 10th Jubilee International Symposium on Applied Computational Intelligence and Informatics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129554184","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}
{"title":"Nonlinear dynamic model identification of airplanes including inertial parameters and force-torque relations based on real flight data","authors":"Lorand Lukacs, B. Lantos","doi":"10.1109/SACI.2015.7208236","DOIUrl":"https://doi.org/10.1109/SACI.2015.7208236","url":null,"abstract":"The primary scope of the paper lies on the identification of an aircraft's nonlinear dynamic model together with the inertial parameters (center of mass and inertia matrix). It is assumed that the aircraft has no inbuilt navigational system, nor any sensors mounted on its control surfaces. The flight of the airplane is influenced by the control column and pedals manipulated by the pilot whose positions can only be observed visually. For the time of data logging, an external sensory system (GPS, IMU) and a camera system were deployed on the airplane supporting the collection of flight data for state estimation and model identification. An earlier paper discussed the computation of the actuator signals and the state estimation. The present paper concentrates on the identification of the unknown COG and inertia matrix together with the force-torque model if the sensory information is available in a frame parallel with the geometrically chosen frame of the airplane. The force-torque model is based on the dynamical equations of rigid body with additional weighted nonlinear terms for 3D forces and torques. Dominating nonlinear functions are selected by physical considerations and their parameters are determined using SVD technique. From the inertial parameters only the mass is known. Wind effects are taken into consideration. Inertial parameters are computed by constrained global search based on an appropriately chosen objective function. The results are presented for a sailplane using real flight data.","PeriodicalId":312683,"journal":{"name":"2015 IEEE 10th Jubilee International Symposium on Applied Computational Intelligence and Informatics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130036281","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}

Human conversation is also considered multimodal, and a great amount of research is done worldwide to engineer novel robotic systems, with more and more intelligence for human gestures or speech recognition abilities enhancements embedded within them. This paper presents a Fractional Fourier transform-based strategy for multimodal communication abilities improvement of pervasive mobile robots. Using a special hardware architecture, based on the standard configuration of the NI SbRIO-9631 prototype robot, a novel voice signals recognition algorithm has been tested and implemented. The experiments prove that the pervasive mobile robot endowed with these additional voice signals analyzing abilities displays more intelligence and cooperativeness in its environment significantly improving human-robot multimodal communication.","PeriodicalId":312683,"journal":{"name":"2015 IEEE 10th Jubilee International Symposium on Applied Computational Intelligence and Informatics","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134358843","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}

Together with the increased usage of these technologies, at the datacenter level we need to know in detail the information flux between the computing nodes. More exactly, on which server the data is processed, how it is manipulated and stored at the physical or virtual level. To have a full picture of what it is going on we need to have a centralized system that can collect data regarding about the datacenters status and correlate them with known anomalies and other usage patterns and in case of a security breach to act accordingly. In this paper we present a new way to monitor running virtual machines existing at a datacenter level. We will talk about the architecture, and how we use the information collected to train our automated anomalies machine learning modules.
