We meant to integrate these models into ona small electrical driving circuit that integrates an onboard microcontroller.We designed the solution by taking into accountthe reduced computing capability of small embedded systems.Direct kinematics (DK), differential kinematics, both direct (J)and inverse (invJ), and a simplified dynamic model will alsobe presented. The novelty of the approach relies in a series ofgeometric properties that allow to reduce the computationalload. When the three kinematics are computed together (DK,J, invJ), their computations can be expressed in few lines ofcode. The accuracy of motion, as well as the reduced computingpower, will be compared to classic algorithms . The proposedalgorithms have been implemented in a working system in thecontext of a telemedicine project.","PeriodicalId":253479,"journal":{"name":"2015 IEEE European Modelling Symposium (EMS)","volume":"9 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":"129235162","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}

For that reason merging models are an important component of microscopic traffic simulation. In this paper an asymmetric two lanes cellular automata (CA) model with an on-ramp for traffic flow simulation is presented. The model takes into account mechanical restrictions of vehicles and drivers psychological behavior and preserves the computational simplicity of CA traffic models. The aim is to explore the usefulness of CA to model and simulate properly the access of vehicles from on-ramps to the main lanes of a road. Extensive simulation results indicate that CA models can adequately capture the complexity, in terms of traffic phases, of on-ramp merging in real traffic and reproduce the bottlenecks induced by large volumes of traffic flow demanding access to the road.","PeriodicalId":253479,"journal":{"name":"2015 IEEE European Modelling Symposium (EMS)","volume":"6 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":"116223604","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 is due to the size and rapid growth of the Web content. The existence of great search engine such as Google or Bing has simplified our searching mission. But those search engines are only efficient if the user submit query that precisely represent the user's search intent to the system. The fact is users are bad in translating their search intent into a query format for the search system to process. Therefore, users reformulate their query several times for getting more relevant results. The aim of this paper is to present evaluation of seven distinct techniques employed in query reformulation process. This work proposes the use of crop characteristic category element in reformulating query, as well as combination with ontology and query keyword elements. The experimental results show that the use of crop characteristic category in reformulating query has significantly improved the search results performance. In the future, it also can be used to replace the ontology element if the ontology is not available.","PeriodicalId":253479,"journal":{"name":"2015 IEEE European Modelling Symposium (EMS)","volume":"97 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":"121244884","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}

There are concerns that the security vulnerabilities in smart metering systems can be exploited on a large scale. On an individual level, smart meters can be made to provide false metering data to the service providers. On the collective level, the smart grids can be attacked to bring down the national grid or parts of it, which is a concern of national security. A list of possible security attacks on the smart metering systems is identified and summarized in this paper. It is well known that secure design patterns reduce the design flaws in a system. State of the art smart metering systems do not follow the standardized software development processes. A security pattern based engineering approach for developing secure software for smart metering systems is introduced in the paper. The secure design patterns are stored in a repository of patterns using pattern modeling tools. The engineering process and corresponding modeling tools were developed during the EU project, entitled \"Trusted Computing Engineering for Resource Constraint Embedded Systems Applications\".","PeriodicalId":253479,"journal":{"name":"2015 IEEE European Modelling Symposium (EMS)","volume":"2021 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":"128062580","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}

Integrating DG into an electricity network, especially close to load centres, has many significant benefits but also brings with it many drawbacks such as voltage drop, and power losses. In this paper the impact of three different types of distributed generation (diesel generator, wind turbine and photovoltaic (PV)) on distribution networks' voltage profile and power losses is studied. NEPLAN software and the extended Newton-Raphson method have been used in the analysis. The obtained results show that different types of DG influence differently the distribution network and that their precise location and size are vital in reducing power losses and improving the voltage stability.","PeriodicalId":253479,"journal":{"name":"2015 IEEE European Modelling Symposium (EMS)","volume":"41 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":"133412447","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 superiority of the method over commonly used \"Code Generation\" tools is also emphasized. First, a MATLAB/Simulink model of the FOC of PMSM drive is developed by using MATLAB programming in MATLAB Functions similar to C coding techniques. The results of the simulation are presented. Then, the MATLAB programming based codes developed in simulation are implemented in a TMS320F28335 floating-point MCU by using C programming language and the experimental results are obtained.

Industrial manufacturing can benefit from the web standards due to the interoperability and simplified application integration. This article reviews the current use of web standards in the industrial automation domain. In addition, the manuscript describes and discusses the potentials of using web standards at all the levels of automation system: from high level web-based user interfaces to the industrial controllers, which are located in the lowest layer of the well-known automation pyramid.

The vehicle is modeled as a continuous system consisting of several subsystems. The discrete model of several sensors and actuators, a decision system, and low-level controllers for acceleration/braking and steering systems are added. Based on this model, a pedestrian avoidance maneuver for typical speeds in city traffic is simullated. When the sensory system detects a pedestrian in the vehicle's path, the decision system calculates its trajectory. Using this information, the speed and/or direction that the vehicle must take in order to avoid the accident are estimated. These values are sent to the low-level controllers of the accelerator/brake and steering, which generate the signals to be applied to such systems to achieve the desired trajectory and speed.","PeriodicalId":253479,"journal":{"name":"2015 IEEE European Modelling Symposium (EMS)","volume":"77 4 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":"133211103","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}

Multiple stenoses can occur along its length. In such cases, two or three overlapping stents are inserted into the artery. Stent overlapping significantly increases the risk of stent fracture. Following restenosis, the procedure can lead to intermittent claudication, limb ischemia and in some cases eventually amputation. The study motivation is to evaluate the outcomes of deploying overlapping stents in terms of stresses exerted on the artery and implants and establish the fact that overlapping stents must not be designed as solitary stents. This study evaluates the stresses overlapping stents exert on the artery and on each other using a numerical (finite element) model. The model formulated comprises the stents and a two layers artery, each layer presenting hyper-elastic mechanical material properties. Results demonstrate significant increase in radial and circumferential stresses exerted on the artery at regions of overlapping stents compared with those of single stents (~50%). With similar results relating to the implant stresses. Therefore, procedures involving overlapping stents must employ uniquely designed implants of axially variable radial stiffness, not as performed today.","PeriodicalId":253479,"journal":{"name":"2015 IEEE European Modelling Symposium (EMS)","volume":"358 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":"133338149","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}
