The vehicle is powered by a new topology of permanent magnet synchronous linear motor. The slider of the motor is integrally attached to the floor of the vehicle to propel. The motor is fed with an alternating voltage conveniently applied to a three-phased stator coils which are distributed in the rails that attach the vehicle travel. Therefore, the motor requires no energy storage system. A set of permanent magnets located on the slider and disposed in Hal Bach array, maximize thrust force. The new slider topology is able to reduce the thrust ripple, while maintaining its average value. At the same time it reduces the normal force, which in this type of motor with ferromagnetic slotted stator, is an attraction force. The study of the dynamic behavior of electromagnetic forces concerning the movement of the slider on the stator is shown as well as the motor structural design. A 3D Finite Element simulation tool is used.","PeriodicalId":253479,"journal":{"name":"2015 IEEE European Modelling Symposium (EMS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132678186","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}

As a case study, the Arability degree of usability for the open source Php My Bibli integrated library system (OS PMB ILS) is computed based on responses collected via a questionnaire from Arab librarians who either use the original French PMB or test the underdeveloped Arabized version. The usability of the original and Arabized PMB is quantified using the ISO quality model and fuzzy multi criteria technique. Then the Arability degree of usability for Arabized PMB is computed. The results show that the quality of the Arabized PMB does not match that of the original and it requires some improvement. Therefore, this paper offers an approach to quantifying Arability degree of usability for Arabized open source software.","PeriodicalId":253479,"journal":{"name":"2015 IEEE European Modelling Symposium (EMS)","volume":"232 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132490754","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}

Huang","doi":"10.1109/EMS.2015.21","DOIUrl":"https://doi.org/10.1109/EMS.2015.21","url":null,"abstract":"The use of ultra-high magnetic fields (more than 7 Tesla) in magnetic resonance imaging (MRI) can provide a much higher signal-to-noise ratio (SNR) compared to commonly used 3T clinical MRI scanners. It will enable the in-vivo imaging of human anatomical details that have never been seen before with other imaging techniques. However, conventional radiofrequency (RF) coils are no longer suitable for providing homogeneous magnetic field (H) distributions. Homogeneity of the magnetic field distribution is an essential property of MRI coils. The uniform H-field distribution of the coils is important for accurate description of the interaction of the electromagnetic waves with the human body. Therefore, with the increase of the main magnetic field, novel RF technology and coil designs are needed. In this paper, we present a new human head coil design for 10.5 Tesla MRI scanner. This novel design provides homogeneous coil sensitivities in the area of interest according to the simulation results. First measurements of the fabricated prototype demonstrated strong resonance at the desired frequency.","PeriodicalId":253479,"journal":{"name":"2015 IEEE European Modelling Symposium (EMS)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116263276","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}

This paper brings both together by using Logic-Labeled Finite-State Machines to deploy executable models of embedded systems and also to configure the corresponding tests. The advantage is a much more efficient validation of the models, with more robust and durable representations, that ensure effective and efficient quality assurance throughout the development process, saving the costly exercise of formal model-checking until the system is complete enough to meet all requirements.","PeriodicalId":253479,"journal":{"name":"2015 IEEE European Modelling Symposium (EMS)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133824512","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}

Our goal is to work out an appropriate model that allows us to obtain the vehicle inductive signatures by means of a simulator to extract some features and/or study several performances without making use of expensive, not only in time but also in resources, tests in real scenarios using our hardware prototype. As it is shown with the results obtained using both the prototype and the inductive sensor simulator, the vehicle signatures in time and frequency domains exhibit similar characteristics, which validates the model proposed in this work. Moreover, a spectral feature extracted from the signatures in the frequency domain is studied using our software, giving us as a result that such a indicator suffers negligible variations with the vehicle speed or acceleration, but depends on its length i.e., on the vehicle type. This remarkable dependence can be exploited for vehicle classification tasks.","PeriodicalId":253479,"journal":{"name":"2015 IEEE European Modelling Symposium (EMS)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126171147","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 evaluation of a project portfolio must consider the variety of project sizes that may be met, so that a proper model should be adopted to describe that variety, especially for its use in simulation. In this paper, a log-normal probability model is suggested to describe the dispersion of project sizes within a project portfolio. The model is obtained on the basis of two real datasets spanning over ten years of observations, and after comparison with competing Gamma and Pareto models. The parameters of the log-normal model are provided as resulting from the best-fit procedure, and indications are also given for the values to use in a simulation study.","PeriodicalId":253479,"journal":{"name":"2015 IEEE European Modelling Symposium (EMS)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121503642","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}

Engelstad","doi":"10.1109/EMS.2015.13","DOIUrl":"https://doi.org/10.1109/EMS.2015.13","url":null,"abstract":"Security levels used in organizations today are typically course-grained, broad and distinct, using security levels such as \"Confidential\" and Secret\". However, current research is advocating a move towards more fine-grained security models, e.g. Such as Attribute-Based Access Control, where information objects and end-users are characterized in terms of complex meta-data. One idea promoted is a topic-oriented approach where information objects are characterized in terms of fine-grained descriptions of the topics of its content. It will lead to higher flexibility, but will also rely on a policy-database to assign a specific security policy to topics and subtopics. Due to increased complexity, it will also require automatic or semi-automatic tools for determining the topics and sub-topics of information objects, and the tools should extract topics that are easily understood by humans, since humans need to control the policy. This paper studies the feasibility of using clustering techniques to help humans in extracting the topics from information objects. A number of clustering methods are discussed, including k-means, Ward's hierarchical agglomerative clustering, Correlated Topic Models (CTM) and Latent Dirichlet Allocation (LDA). To the best of our knowledge, an in-depth analysis on the feasibility of using clustering for this problem has not been presented in previous work. Our analysis points out challenges with clustering in particular, which must be addressed before realizing the general vision of topic-oriented policy-driven security models.","PeriodicalId":253479,"journal":{"name":"2015 IEEE European Modelling Symposium (EMS)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123238361","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}

In these days and thanks to high technology, many companies offer different types of expensive tables to serve patients in this domain which pulls them away from the guidance of the National Institute for Health and Clinical Excellence (NICE). NICE believes that patient care can be achieved by considering validity and cost-effectiveness as a type of treatment. As the number of cases of backache increases, it has become so important to find a definitive treatment of this disease. This work will enhance nonsurgical treatments for various disc diseases by the auto-traction device approach. Rest in bed will hurry the process of pain relief but it may take weeks. By means of mechanical auto-traction, one can achieve in minutes or hours what might take days or weeks in bed. The Disc Rehabilitation Table (DRT) function is to space between vertebrae that can help strengthen the spinal column and the supporting muscles, ligaments, and tendons. It is very safe and very effective not only at early stages, but also for complicated disc problems.","PeriodicalId":253479,"journal":{"name":"2015 IEEE European Modelling Symposium (EMS)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128723417","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}
