Such an understanding is fundamental in bioengineering where engineers seek a simpler description of the underlying multi-scale processes that occur, for example, when tissues are mechanically stressed or strained. Fractional order models work well in physics, electrochemistry and rheology, particularly in describing dielectric, magnetic and viscoelastic materials over extended ranges of time and frequency. In heat transfer and electrochemistry, for example, the half-order fractional integral is the natural integral operator connecting applied gradients (thermal or material) with the resultant diffusion of ions or heat. Can fractional calculus be applied in bioengineering to uncover similar relatively simple links between stress and strain in load-bearing tissues, such as cartilage, the electrical impedance of implanted cardiac pacemaker electrodes, or in predicting changes in the shear modulus of tumors developing in breast tissue? Since the constitutive properties of tissue depend on the micro-scale architecture of the cellular and extracellular networks, the challenge for the bioengineer is to develop new modeling, visualization and assessment tools that better predict the macro-scale mechanical performance from measurements observations at the micro- and nano-scale. In this paper I describe some of the characteristics of fractional calculus that I believe make it well suited for this application, and outline three areas of bioengineering research where fractional calculus is being applied.","PeriodicalId":334936,"journal":{"name":"Proceedings of the 13th International Carpathian Control Conference (ICCC)","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123437738","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 the introduction of contribution an analysis is given of biomass in terms of its occurrence, composition, and caloric value and also in terms of processes taking place with the biomass gasification and combustion. The idea for a complex model for the gasification and combustion of biomass is derived from the initial process analysis, which was suggested as a synthesis of elementary process models. In the case of elementary models the heating model, drying model, thermal decomposition model, oxidation of the solid component model, and oxidation of the volatile component model are considered. The heating model is based on the processes of heat accumulation and the transfer of heat by convection. The basis of the evaporation model is a process of the transformation of liquid water into water vapour. The remaining three models include the thermal decomposition of biomass, release of the volatile components and the burning of the solid components from it. Elementary process models were independently implemented and verified in a MATLAB environment as individual m-functions. The results from the simulations are also stated in this contribution, which are analyzed, and further use and method of model gasification and combustion is suggested.","PeriodicalId":334936,"journal":{"name":"Proceedings of the 13th International Carpathian Control Conference (ICCC)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121482925","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}

Present trends in the complex process control design demand an increasing degree of integration of numerical mathematics, control engineering methods, new control structures based of distribution, embedded network control structure and new information and communication technologies. Furthermore, increasing problems with interactions, process non-linearity's, operating constraints, time delays, uncertainties, and significant dead-times consequently lead to the necessity to develop more sophisticated control strategies. Advanced control methods and new distributed embedded control structures represent the most effective tools for realizing high performance of many technological processes. Main ideas covered in this paper are motivated namely by the development of new advanced control engineering methods (predictive, hybrid predictive, optimal, adaptive, robust, fuzzy logic, neural network) and new possibilities of their SW and HW realizations and successful implementation in industry.","PeriodicalId":334936,"journal":{"name":"Proceedings of the 13th International Carpathian Control Conference (ICCC)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128437952","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}

Outside-in approach is user oriented. Process is forced to satisfy user objectives. Inside-out approach is process oriented. At this process driven approach process has dominant position and conditions have been created to realize it by the most natural way. Process oriented approach is based on knowing process fundamentals, where all control activities tend to satisfy the process optimally. This approach can bring important changes to the process. Presently in most of the solutions some regard is given to the process, but real process oriented approach is more exception than the rule. In this paper individual solution presents conceptual advantages of this approach and classical conceptions. External manipulation is by domination of the object by the subject. Object is passive and is waiting on the intervention. In the process approach the object is active and requires minimum external forces. Process is executed by transformation, mutation and alteration. Process manipulation can be physical or logical (process activation, deactivation).","PeriodicalId":334936,"journal":{"name":"Proceedings of the 13th International Carpathian Control Conference (ICCC)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133439272","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}
