LQR, an optimal control technique, and PID control method, both of which are generally used for control of the linear dynamical systems have been used in this paper to control the nonlinear dynamical system. The nonlinear system states are fed to LQR which is designed using linear state-space model. Inverted pendulum, a highly nonlinear unstable system is used as a benchmark for implementing the control methods. Here the control objective is to control the system such that the cart reaches at a desired position and the inverted pendulum stabilizes in upright position. The MATLAB-SIMULINK models have been developed for simulation of control schemes. The simulation results justify the comparative advantages of LQR control methods.","PeriodicalId":407900,"journal":{"name":"2012 Sixth Asia Modelling Symposium","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116223363","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}

A simulation environment seemed to be then essential, since the test of the hardware and software is hard and difficult. Beyond cost and time savings, the simulator offers the great opportunity to extend the potential and the features of WSN. As there are many simulators, we make an attempt in this paper to specify the important ones related to energy consumption. In fact, we discuss the performance, reliability and usefulness of each of them to better see the disadvantages of these simulators and their strong points to be able to develop a better model.","PeriodicalId":407900,"journal":{"name":"2012 Sixth Asia Modelling Symposium","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124984470","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}

A two degree of freedom dynamic model of a vehicle semi-active suspension system was presented. The role of H<sub>∞</sub> is used to minimize the disturbance effect on the system output whereas H<sub>2</sub> is used to improve the transients against random disturbances. The capability of the system of improving comfort of operators has been evaluated through simulations carried out with a validated model of the entire vehicle. The results of this study revealed that the use of mixed H<sub>2</sub>/H<sub>∞</sub> with pole placement for a semi-active suspension system showed a great improvement compared with H<sub>∞</sub> systems. In addition, the results of the simulation showed that ride comfortable of the vehicle can be improved effectively by using the semi-active suspension with mixed H<sub>2</sub>/H<sub>∞</sub> control method, and also the mixed H<sub>2</sub>/H<sub>∞</sub> control method more effective than the H<sub>∞</sub> control method.

This improves the flexibility of FDTD method. Hence, simulation results are able to give a clear and accurate view of this dynamic phenomenon.

This requires an exact probe position and angulation to capture the cervix image. In this paper, we present a new method to detect cervix in the best position and angulation. More than 100 samples were processed and analyzed. Image enhancement of the ultrasound image data was performed before further processing and cervix detection. The best cervix ultrasound image was used as a reference template for analysis. The correlation between template and target image was compared using squared error subtraction of histograms. Test results show that taking a different rate threshold at 0.075, an accuracy of 100% for cervix identification is achieved. This method is very efficient since it uses a simple algorithm and requires low memory capacity. This technique will be powerful to be used for real time autonomous scanning of cervix for surgical monitoring or acceptable operator-independent cervix screening.","PeriodicalId":407900,"journal":{"name":"2012 Sixth Asia Modelling Symposium","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124339878","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 unpredictable behavior is a result of the spread of influence and action of each individual against another individual in the crowd. Iterative process that happens constantly can lead to an uncontrolled accumulation of actions. This paper is our first study to apply psychological behavior of crowd into a group of humanoid robot. Our goal in this research is having a group of robots that behave like a human crowd. The psychology theory to be implemented into our robot's behavior is Le Bon's \"Suggestibility theory\". In this paper, robots will consider as a multi-agents system which has distinct different psychological characteristics on each agent. In reviewing the propagation process of psychological variable on each agent, we used a model known as Psychological Dynamic Model (PDM).

This situation calls for immediate, yet effective, solutions to avoid further financial losses and intellectual property violations. Audio and speech watermarking has been proposed as a possible solution, since this technology embeds copyright information into audio files as a proof of their ownership. In this paper, we propose an effective, robust, and an inaudible audio and speech watermarking algorithm. The effectiveness of the algorithm has been brought by virtue of applying a cascade of two powerful mathematical transforms; the discrete wavelets transform (DWT) and the singular value decomposition (SVD). Experimental results will be presented in this paper to demonstrate the effectiveness of the proposed algorithm.","PeriodicalId":407900,"journal":{"name":"2012 Sixth Asia Modelling Symposium","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130080297","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 input and output data obtained from the simulation of the analytical model is used for the identification of the system. The simplest polynomial form, auto-regressive, external input (ARX) model structure is chosen and the performance of the system is validated by mean square error (MSE) and correlation tests.

In this paper, we investigate the effect of seven process parameters and two process noise parameters on threshold voltage (Vth) in a 32nm PMOS transistor. Using Taguchi's experimental robust design strategy seven process parameters were assigned to 7 columns of the L18 orthogonal array to conduct 18 simulation runs. Fabrication of the 32nm PMOS transistor was simulated by using the fabrication tool ATHENA and electrical characterization was simulated using ATLAS. These simulators were used for computing Vth simulations for each row of the L18 array with 4 combinations of the 2 noise factors. Taguchi's nominal-the-best S/N ratio was used as the objective functions for the minimization of variance in Vth. The best settings of process parameters were determined using Analysis of Mean (ANOM) and Analysis of Variance (ANOVA) for reducing the variability of Vth. The best settings were used for verification simulations and the results showed that the Vth values had the least variance and the mean value could be adjusted to-0.103V +-0.003 for PMOS, which is well within ITRS specifications.","PeriodicalId":407900,"journal":{"name":"2012 Sixth Asia Modelling Symposium","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133537333","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 algorithm involves neighborhood and global search and is able to find promising solutions to complex multimodal optimization problems. The purpose of neighborhood search is to intensify the search effort around promising solutions, while global search is to enable avoidance of local optima. Normally, a symmetrical search neighborhood is employed in the Bees Algorithm. As opposed to this practice, a TRIZ-inspired asymmetrical search neighborhood was tried in this work to explore the significance of neighborhood symmetry. The algorithm with an asymmetrical search neighborhood was tested on an engineering design problem. The analysis verified that under certain measurements of asymmetry, the proposed algorithm produced a similar performance as that of the Bees Algorithm.","PeriodicalId":407900,"journal":{"name":"2012 Sixth Asia Modelling Symposium","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121158522","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}
