Standard risk metrics like volatility or downside risk are deconstructed into five general sub-functions for reference, selection, penalization, normalization and re-dimensioning. The advantage of this approach is its flexibility, allowing modeling a wide range of risk perceptions in numerous application fields of discrete event simulation. Several further risk types like upside risk, outside risk, transition risk, critical state risk or countermovement risk are describable and embeddable as special cases of generalized deviation. These risk types are presented with respect to motivation, specification of relevant generalized deviation components, description of application classes, application examples and graphical illustrations. In particular, various options for determining reference states, reference selection and penalty functions are discussed. Implementation features of the generalized deviation metric in the discrete event simulation framework DESMO-J are outlined. Moreover, possible structural extensions as well as additionally implementable risk types are delineated, indicating further application potential and the flexible scope of this approach. It is proposed to complement descriptive standard statistics in discrete event simulation domains by additionally employing risk measurement in terms of generalized deviation as explicated here, to facilitate assessment of undesired simulation dynamics in various application fields.","PeriodicalId":386945,"journal":{"name":"2013 8th EUROSIM Congress on Modelling and Simulation","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123835488","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}

As velocity is calculated as distance per time, the accuracy and reliability of PWV measurements depends heavily on the estimation of the pulse transit time (PTT). Several methods for the estimation of the PTT exist, often resulting in different PWV values. They rely on the exact determination of specific points in the pulse wave, which are easily affected by small changes of the signal. As there is still no agreement on the accuracy of these methods, only the reliability and stability of these commonly used \"foot-to-foot\" algorithms are compared in this paper. These algorithms are based on the detection of the diastole-minimum, the maximum of the first or second derivative or combinations thereof. We also adapted a new approach called \"diastole-patching\" based on the matching of a specific region of the pulse waves. The methods were tested using 2348 pulse waves from the MIMIC Database, collected from 46 subjects. Intra-subject deviation and relative outliers per subject were lowest in the adapted diastole-patching algorithm (4.9 ± 3ms and 0.6 ± 2.7%, respectively). Therefore, this study has shown that the diastole-patching method is the most stable and reliable of the algorithms under investigation.","PeriodicalId":386945,"journal":{"name":"2013 8th EUROSIM Congress on Modelling and Simulation","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117041650","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 composition and flow rates of industrial wastewater fluctuate depending on the production schedules of the upstream processes. A lot of process measurements are available, but measurement sets do not include sufficient information on the special features of the influent nor on the microbial composition of the sludge. The populations of microorganisms have an essential effect on the operation of the treatment process. Basic dynamic simulation is done with linguistic equation (LE) models, where interactions are handled with linear equations, and nonlinearities are taken into account by scaling functions. Intelligent indices provide useful information for the detection of process conditions and the system, which consists of three interactive models: load, biomass population and treatment. Process insight is maintained while data-driven tuning relates the measurements to the operating areas. A wide range of operating conditions is handled with a multimodel system and a fuzzy decision module, which defines the weights of the subsystems. Hybrid models with a cascade approach are needed in biological wastewater treatment to cover different operating conditions.","PeriodicalId":386945,"journal":{"name":"2013 8th EUROSIM Congress on Modelling and Simulation","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115574625","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}
