{"title":"Probabilistic Finite Element Prediction of the Active Lower Limb Model","authors":"C. Arsene, D. Al-Dabass","doi":"10.1109/ISMS.2012.54","DOIUrl":"https://doi.org/10.1109/ISMS.2012.54","url":null,"abstract":"The scope of this paper is to explore the input parameters of a Finite Element (FE) model of an active lower limb that are most influential in determining the size and the shape of the performance envelope of the kinematics and peak contact pressure of the knee implant introduced during the Total Knee Replacement (TKR) surgery. The active lower limb FE model simulates the stair ascent and it provides a more complicated setup than the isolated TKR model which includes only the implant femoral component and the implant tibial insert. It includes bones, TKR implant, soft tissues and applied forces. The kinematics of the FE model is reported in the Grood and Suntay system, where all motion is relative to the femoral component of the TKR. Reported tibial component kinematics are tibial-femoral flexion angle, anterior-posterior displacement, and internal-external rotation, while the reported patella kinematics are patella-femoral flexion angle, medial-lateral shift and medial-lateral tilt. Tibial-femoral and patella-femoral contact pressures are also determined. Two probabilistic methods are used together with the FE model, which is termed probabilistic FE analysis, to generate performance envelopes for the reported output kinematics and peak contact pressures and to explore the input parameters: the Monte Carlo Simulation Technique (MCST) and the Response Surface Method (RSM). It is considered a large set of 77 input variables of the FE active lower limb model which have associated a Gaussian variability. Following a sensitivity analysis with the RSM, a reduced set of 22 input variables is derived, which represent the key parameters which influence the performance envelopes. It is shown that the envelopes of performance obtained with the probabilistic FE analysis using the RSM with the reduced set of 22 input variables are similar with the envelopes of performance obtained with the probabilistic FE analysis using the MCST with 800 points for the same degree of variability in the 22 input key parameters. The findings of this work are paramount to the orthopedic surgeons who may want to know the key parameters that can influence the performance of the TKR for a given human activity.","PeriodicalId":200002,"journal":{"name":"2012 Third International Conference on Intelligent Systems Modelling and Simulation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129054432","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}

One of the benefits of fuzzy controllers is their ability to control unidentified processes which lets a model free controlling scheme; but on the other hand, an efficient fuzzy direct controller design, strictly depends on human expert and knowledge of a certain process. This will limit the ability of noncontrol specialists to apply fuzzy controllers on various ranges of plants. In this paper, a fuzzy direct controller is optimized in rule base using Particle Swarm Optimization algorithm. The optimization is performed subjected to minimize the output error surface of a nonlinear water level tank process. An offline Sugeno-Fuzzy system identifier is employed to prepare the evaluation function for particle swarm algorithm. Results show that the proposed controller performance is much better than simple human knowledge tuned controller.","PeriodicalId":200002,"journal":{"name":"2012 Third International Conference on Intelligent Systems Modelling and Simulation","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131156196","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 most common failure of the insulation occurs due to the surface insulation failure and the discharges within the void. In this regard, the monitoring and prevention of insulation failure becomes essential for uninterrupted functioning of high voltage power apparatus. Hence the deterioration of Insulation in an Insulator is determined from the analysis of Partial Discharge signals. The Partial Discharge signals are produced by the localized ionization within the electrical field. The Numerical Analysis of Electric field can provide information about the Partial Discharges which is determined by using the Finite Element Method. In this paper the electric field analysis are performed using FEM for the Epoxy insulator at various voltages and frequencies. It can provide information about the degradation of insulation well in advance thus avoiding major break down of power system.","PeriodicalId":200002,"journal":{"name":"2012 Third International Conference on Intelligent Systems Modelling and Simulation","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128373426","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 technique is simpler and faster than conventional one because it requires only real arithmetic computations. This technique is known as discrete Hartley transform and has a closely related with Fourier transform. The performance of OFDM modulator and demodulator based on DHT was carried out with giving binary random data as the data sources. After processed by IDHT as the modulation function, the signals were then transmitted via the dispersive channel with using additive white Gaussian noise (AWGN) as the channel model. The transmitted signals were detected in receiver part with reverse processes as done in transmitter part. The measurements of parameters were repeated five times to obtain and to calculate the accuracy of the new system. The plotted graph of average BER versus SNR showed that the BER was decreased when the given value of SNR was increased. The analysis of system performance was also evaluated for several numbers of subcarriers used and the results showcased some advantages. The modification of DHT algorithm is expected to reduce the complexity and time consuming for long-length of computational on the performing of OFDM modulator and demodulator based on DHT.","PeriodicalId":200002,"journal":{"name":"2012 Third International Conference on Intelligent Systems Modelling and Simulation","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128537189","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":"Tutorial: Privacy Preservation in MANET: Issues and Challenges","authors":"D. K. Mishra","doi":"10.1109/ISMS.2012.148","DOIUrl":"https://doi.org/10.1109/ISMS.2012.148","url":null,"abstract":"Summary form only given. Sometimes the physically distributed computing devices in a network may be interested in computing some function of their private inputs without disclosing these inputs to one another. This type of computation falls under the category of Secure Multiparty Computation (SMC). The solution to SMC problems in Mobile Ad hoc Networks (MANET) can be found with the modification of the data inputs or with some anonymization technique. MANETs are the wireless networks of the mobile computing devices with no support of any fixed infrastructure. The mobile nodes use any of the radio technology like Bluetooth, IEEE 802.11 or Hiperlan for directly communicating with each other. The nodes behave as hosts as well as routers. The security challenges in the MANET arise due to its dynamic topology, vulnerable wireless link and nomadic environment. An identification mechanism is needed between the nodes using identification and the credentials. This security architecture simultaneously leads to privacy problems. Some mechanism is needed which prevents a node to learn the identity or the credentials of other nodes. To provide location privacy in MANET is a nontrivial task. Current routing protocols do not focus much on the security and the privacy issues. These aspects are postponed till further development. An authentication protocol is needed between nodes using some cryptographic technique. In service-oriented MANET the denial of the service must be taken care of so that the availability of the service is maintained. The security requirement of the ad hoc network depends on its application. For example, for a simple business meeting the requirement is mitigated and for the military battlefield it is severe. Thus no general security architecture can be developed for MANET. Specific security architecture is needed for specific application. Much security related work is still pending and will add to the standards as the physical deployment of the MANET will grow. In this talk, an emphasis is made on how SMC solutions can be used for privacy preservation during computation.","PeriodicalId":200002,"journal":{"name":"2012 Third International Conference on Intelligent Systems Modelling and Simulation","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115809502","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}
