Proposed is a model with a hierarchical structure with three levels: the macroscopic level of a reactor, microscopic level of a cell population, and molecular level of protein interactions with cyclin dependent kineases. The macroscopic model provides basis for production process control by optimal feeding of nutrients and growth factors during cultivation. The microscopic model simplifies a cell population into three pools of cells: P proliferating, Q quiescent, and D dead cells. Dynamics of cell population is determined by the least square estimation of the specific rates of the pool transitions. The molecular model enables theoretical basis for prediction of G1/S transition and the rate of transition from proliferating cells into quiescent state. Conceptual application of the molecular model in conjunction with the mammalian cell production system is discussed","PeriodicalId":320305,"journal":{"name":"26th International Conference on Information Technology Interfaces, 2004.","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133675263","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 simulation speed is improved by using better simulation algorithms, or by using more processing power. The level of details is managed by the most appropriate modeling scale. The simultaneous usage of multiple scales gives multiscale models. We have implemented a prototype simulator in order to investigate the possibility of using agents in multiscale modeling.

The method enables quick, simple and accurate prediction of alpha and beta protein folds on a personal computer by means of few binary patterns of coded amino acid and nucleotide physicochemical properties. The algorithm was tested with machine learning SMO (sequential minimal optimisation) classifier for the support vector machines and classification trees, on a dataset of 140 dissimilar protein folds. Depending on the method of testing, the overall classification accuracy was 91.43%-100% and the tenfold cross-validation result of the procedure was 83.57%->90%. Genetic code randomisation analysis based on 100,000 different codes tested for the protein fold prediction quality indicated that: a) there is a very low chance of p=2.7times10-4 that a better code than the natural one specified by the binary coding algorithm is randomly produced, b) dipeptides represent basic protein units with respect to the natural genetic code defining of the secondary protein structure","PeriodicalId":320305,"journal":{"name":"26th International Conference on Information Technology Interfaces, 2004.","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130166045","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 direct application of the EM algorithm to a data set following designed experiments such as randomized block designs, or factorial experiments, with missing observations may lead to the estimation of parametric functions that are not estimable. In this paper we present an adjustment of the EM algorithm for additive classification models that prevents the user from obtaining results, which are not reliable. The adjustment consists in applying the R-process introduced by Birkes, Dodge and Seely (1976), that determines which are the estimable parametric functions. The observations and the parameters are then partitioned in a suitable way, and the maximum likelihood estimates for the estimable parametric functions are derived applying EM to each partition. The proposed algorithm is called REM; several numerical examples and one application are presented","PeriodicalId":320305,"journal":{"name":"26th International Conference on Information Technology Interfaces, 2004.","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129447855","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}

Practical considerations relating to specifically determined conditions in a particular network, including the topology and interdependencies with other implemented technologies, additionally define the selection framework of a corresponding internal routing protocol.
