Candide wire frame model is adapted properly on the first frame of face image sequence. Facial features in subsequent frames of image sequence are tracked using active appearance algorithm. The algorithm adapts Candide wire frame model to the face in each of the frames and tracks the grid in consecutive video frames over time. Last frame of image sequence corresponds to greatest facial expression intensity. The geometrical displacement of Candide wire frame nodes, defined as the difference of the node coordinates between the first and the greatest facial expression intensity frame, is used as an input to the support vector machine, which classifies facial expression into one of the class such as happy, surprise, sad, anger, disgust and fear.","PeriodicalId":131364,"journal":{"name":"2011 UKSim 5th European Symposium on Computer Modeling and Simulation","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124978193","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 overcoming this problem, security tools introduce newer patches, thereby the size of database and computation overloads are increased. By Biological Immune System (BIS) modeling and simulation, its behavior in different situations will be considered and the effect of database size and learning ability in robustness of the BIS will be evaluated. For the BIS modeling and simulation, Biological Agent will be introduced and a Multi Agent System in Net logo software has been designed. According the results of simulation, the effect of learning rate in different states in system's robustness has been evaluated. Furthermore, robustness of the systems with different sizes of database in the initial state has been considered.

The suggested Regularized Constrained Gauss-Newton (RCGN) algorithm determines the dielectric distribution of the internal fluid by solving the inverse and forward problems on the data captured from both the electrical electrodes surrounding the pipeline and the pressure and temperature sensors distributed at different locations of the target process. By measuring the pressure and temperature at different locations of the target, an estimation of its density distribution is performed using its fluid mechanic properties. Experimental results on a set of different images clearly show that the proposed method achieves more accurate results than the traditional methods which use only boundary electrodes, while keeping the computation time almost same.","PeriodicalId":131364,"journal":{"name":"2011 UKSim 5th European Symposium on Computer Modeling and Simulation","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125376638","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 novelty of the filter is using averaging method of combining mean values of each resolution in approximation spaces that computes the average overall frequency in a specific point. The key structure is a mirror usage of data handling the zero abnormality of the filter in time boundaries. this algorithm is usable for jobs with need of elimination noise that knowing the harmonics is less needed and the smoothing of the conventional filters are much that the data would be deleted. after using this algorithm if needed the conventional low-pass filters can be used to extract smoothed data. this method simplicity is appropriate for micro-controller systems.","PeriodicalId":131364,"journal":{"name":"2011 UKSim 5th European Symposium on Computer Modeling and Simulation","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114229987","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 decision making processes that arise in the design and operation of this kind of systems can be afforded by means of algorithmic methodologies. A large range of approaches based on the simulation of the behavior of the system have been reported to answer this problem. Their main advantage consists of being applicable to most of the systems. An important drawback is the significant computational resources required to perform an exhaustive exploration of the state space due to the combinatorial explosion. A manual choice of a reduced set of configurations to be simulated can be improved by the use of parametric Petri nets and a metaheuristic search of the most promising ones. In this paper, a review of some definitions of parametric Petri net found in the literature is presented, as well as a definition for the general framework of stating optimization problems of both, the operation and the design of the model of the DES. Moreover, a methodology to obtain such a parametric Petri net, called compound Petri net, from an easier-to-obtain set of alternative Petri nets is proposed and an application example is given.","PeriodicalId":131364,"journal":{"name":"2011 UKSim 5th European Symposium on Computer Modeling and Simulation","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114868652","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 derivation of model equations starts by first considering low level of minority carrier injection within the base. A minority carrier profile is obtained by solving electric field equation and current equations for holes and electrons at equilibrium. Next a first order differential equation is obtained for minority carrier distribution. The solution of the differential equation gives the minority carrier profile. In this paper characteristics of the derived equations of minority carrier distribution are studied with the variation of different parameters with reliability.

It has been the key driving force behind the convergence of fixed, mobile and IP networks. Furthermore, real-time applications are making head way in vehicular networks, mission critical and, military applications which use dedicated short range communications (DSRC). 802.11e standards support quality of services (QoS) guarantees in these applications. This is opposed to the problem with 802.11 legacy which is based on distributed coordination function (DCF), and its inability to prioritized applications for service differentiation. Simulation was done on various 802.11e networks which use enhanced DCF (EDCF). In these simulations, it was observed that controlling low priority applications enhances the effectiveness of high priority applications.

The proposed algorithm adjusts inertia weight adaptively to accelerate convergence and utilizes a local search on best swarm to refine obtained responses. To improve the search performance, when the search areas of two swarms are overlapped, the worse swarm will be removed. Moreover, in order to quickly track the changes in the environment, When a changes is revealed in surrounding environment, it causes swarms to be divided into two main parts, the first one is the particles in which are spread up randomly in whole space and then will be clustered to regroup. In the second group, all particles in the swarms convert to quantum particles.
