The model is useful for the design and performance evaluation of the transverse flux machine. The model consists of a series-parallel combination of flux tubes for different parts of the machine including air gaps, the permanent magnet in the rotor, and the stator and rotor ferromagnetic materials. The equivalent circuits of the model are obtained based on permeance calculation of the magnetic flux paths within the machine. A prototype of an 8-pole transverse flux permanent magnet machine has been developed and the analytical modeling approach has been used for modeling of this machine. The validity of the proposed model is verified by comparing the finite element (FE) results with the results obtained from the model and also comparing the measured inductance of the prototype machine with those of predicted based on the analytical model. Comparing the model and measured inductances shows that the analytical model is able to accurately describe the magneto-static behavior of the machine with an average error less than 7%.","PeriodicalId":387483,"journal":{"name":"2011 21st International Conference on Systems Engineering","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133454349","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}

Although there is necessity for thourough testing, exhaustive validiation and verification is hardly possible in industry due to time and resource restrictions. In the past the reason for this has often been that it was to time-consuming to specify, to execute, and to evaluate test cases for the first design models and the integrated embedded system. In the meantime methods have become popular in industry that allow the automated generation, execution, and evaluation of test cases. In order to be able to automate these steps all necessary information must be integrated into the models that are the basis for the following steps. The complexity of the system, however, makes the evaluation and assessment of the behavior of the system even more complex. The growth of information needed for this comes along with it. The integration of this information into the model which is used for the generation of test cases is hardly feasible. In this paper we describe how this issue can be addressed by the combination of reference models in MATLAB/Simulink with test models. Time Usage Models (TUM) are employed as test models and provide the basis to generate all possible test scenarios. Model based statistical testing with consideration of time and durations is supported by TUMs. The reference models are used like an executable specification, providing information for the evaluation of the system to be tested. The test model can therefore be kept generic in order to be able to derive virtually any test case from the model, taking account of the potentially infinite sequence of inputs reactive systems might process. We applied the presented approach with a german automotive OEM for the validation and verification of the energy management system.","PeriodicalId":387483,"journal":{"name":"2011 21st International Conference on Systems Engineering","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125011079","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 proposes an architecture, a Mobile Phone-Based Antenatal Care Support System (MPACSS) that addresses the solution to these drawbacks. MPACSS consists of a patient's mobile phone, hospital server, an Electronic Medical Record System (EMRS), and a doctor's remote terminal. The patient's mobile phone has the interface that allows patients registration and login details, with an in-built diagnostic application. The hospital server accepts the patients' data from the mobile phone and adopts expert system for diagnosis and treatment, while the EMRS manages the database of patients. The doctor's remote terminal is a mobile device with same interface as the patient's mobile device. The doctor only makes a request for the physical presentation of patients depending on the level of severity which is calculated based on fuzzy logic paradigm The proposed system is in its current stage of implementation but an evaluation was carried out on 180 pregnant women and 50 doctors. The result showed 92% efficiency of the system by doctor and 95% usability acceptance by pregnant women. This shows that the system can effectively provide antenatal support to women without any time and distance barriers.","PeriodicalId":387483,"journal":{"name":"2011 21st International Conference on Systems Engineering","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123500921","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}
