The aim is to use the model for subsequent control optimisation and further for control system design. The underlying physical relations of an AHU are investigated through a white-box model. Based on the white-box model considerations a discrete-time bilinear black-box model is proposed. The AHU cooling/heating capacity is altered by means of water valves. The valve introduces a Hammerstein nonlinearity on the system input, which needs to be additionally identified together with the dynamic bilinear model representing the heating/cooling coil of the AHU. The discrete-time model coefficients are then estimated based on real measurements.","PeriodicalId":387483,"journal":{"name":"2011 21st International Conference on Systems Engineering","volume":"13 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":"121041720","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}

In this paper, from the view points of long-term preservation of digital contents, we focus on the the urgent task of storage system, since the size of the web archive is increasing exponentially. In order to archive monotonously increasing contents, we discuss management of storage devices and file formats in web archive systems. Firstly, we propose an architecture of hierarchical storage system based on characteristics of storage devices and file compression formats. Next, we modify the file moving algorithm by using file access frequency. We also evaluate the performance of our proposed algorithm with predicted data based on actual statistics of a web archive system.","PeriodicalId":387483,"journal":{"name":"2011 21st International Conference on Systems Engineering","volume":"283 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":"116089370","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}

In digital image watermarking, robustness and imperceptibility compete with each other. In this paper we applied a hybrid intelligent algorithm based on genetic programming and particle swarm optimization to make a trade off between robustness and imperceptibility. In this way the intelligent method has been applied in DCT_DWT_SVD domain. First of all the original image is transformed into DCT domain and then a part of DCT matrix is decomposed into four subbands using discrete wavelet transform and finally the singular values of each subband are shaped perceptually by singular values of watermark image to embed the watermark. The optimization problem which is related to a conflict between robustness and imperceptibility is solved by means of genetic programming and particle swarm optimization, simultaneously, to achieve the best performance in robustness without losing the quality of host image. Experimental results show improvement in imperceptibility and robustness under several attacks and different images.","PeriodicalId":387483,"journal":{"name":"2011 21st International Conference on Systems Engineering","volume":"57 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":"123553952","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}

However, using these methods for reliability analysis of sequential logic circuits will lead to inaccurate results, because of existence of loops in their architecture. In this paper a new method is proposed based on converting the sequential circuit to a secondary combinational circuit and applying an iterative reliability analysis to the resulting configuration. Experimental results demonstrate good accuracy levels for this method.","PeriodicalId":387483,"journal":{"name":"2011 21st International Conference on Systems Engineering","volume":"74 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":"122527431","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}

Some issues related to resources provisioning in virtual networks are discussed taking into account various approached to estimate required amount of resources for virtual networks and various techniques to control virtual network resources utilization.

A description of the heating system model, its behaviour and underpinning processes are presented. The model of the heating system, which is inherently nonlinear, is formulated either as a linear time varying (LTV) system or a bilinear time varying (BTV) system or bilinear time invariant (BTI) system. For each model representation various formulations of generalised predictive control (GPC) are investigated. The original GPC, in its non-incremental and modified forms are implemented and tested for these systems. Depending on the model structure, i.e whether the model is LTV, BTV or BTI, the GPC is formulated as a linear self tuning control (LSTC) GPC, bilinear self tuning control (BSTC) GPC and fixed bilinear (FB) GPC, respectively. It is shown that depending on the adopted model representation various degrees of improvement are possible when using different formulations for GPC.","PeriodicalId":387483,"journal":{"name":"2011 21st International Conference on Systems Engineering","volume":"1 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":"125828633","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}
