2. 1. State-Oriented Business Process Modeling : Principles, Theory and Practice

   Author : Ilia Bider; KTH; []
   Keywords : business process; dynamical system; formal semantics; persistent action; law-based programming; business analysis; business modeling; object-oriented modeling; conceptual modeling; workflow;

   Abstract : In the last 50 years, a considerable amount of research workhas been completed in the mathematical system theory and theoryof control. Implementation of the results from this researchinto practice has drastically decreased the production costs.Most production processes are highly automated, and the use ofrobots in industry is growing.

4. 2. Four Proposals for Enterprise Modeling

   Author : Darek Eriksson; Chalmers University of Technology; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; change; development; enterprise; modeling process; enterprise modeling language; systems science; constructivist epistemology; organization; modeling; multi-modal modeling; model;

   Abstract : Any enterprise whether a major corporation, a small family-owned business, a public school, a hospital, or a military unit needs to develop itself continuously in order to adapt to the challenges originating within itself and from its environment, in relation to its overall purpose or mission. Deliberate development and management of an enterprise manifest complexity that gives rise to a central challenge: how can we obtain a comprehensive intelligibility of an enterprise? One conceptual tool to overcome this challenge is enterprise modeling; it supports articulation of an enterprise and consequently intelligibility of its complexity. READ MORE

5. 3. Modeling Organizational Dynamics : Distributions, Networks, Sequences and Mechanisms

   Author : Hernan Mondani; Fredrik Liljeros; Rickard Sandell; Stockholms universitet; []
   Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; organizational dynamics; social organizing; organizational change; modeling; organizational growth; process stability; labor flow network; employment trajectories; heavy-tailed distributions; complex network analysis; sequence analysis; agent-based modeling; sociophysics; Sociology; sociologi;

   Abstract : The study of how social organizations work, change and develop is central to sociology and to our understanding of the social world and its transformations. At the same time, the underlying principles of organizational dynamics are extremely difficult to investigate. READ MORE

6. 4. Hybrid Solvents based on Ionic Liquids/Deep Eutectic Solvents for CO2 Separation : Experiments, Modeling, Process Simulation and Evaluation

   Author : Chunyan Ma; Xiaoyan Ji; Päivi Mäki-Arvela; Luleå tekniska universitet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; CO2 separation; Ionic liquids; Deep eutectic solvents; Cosolvent; Thermodynamic modeling; Process simulation and evaluation; Energiteknik; Energy Engineering;

   Abstract : CO2 separation plays a vital role in reducing CO2 emissions to combat climate change, in which solvent-based absorption is widely considered the most promising technology. Many conventional chemical and physical solvents have been introduced for CO2 separation, still facing challenges. READ MORE

7. 5. Modeling and Control of Bilinear Systems : Application to the Activated Sludge Process

   Author : Mats Ekman; Bengt Carlsson; Claes Breitholtz; Uppsala universitet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bilinear systems; modeling; optimal control; parameter estimation; errors-in-variables; activated sludge process; Automatic control; Reglerteknik;

   Abstract : This thesis concerns modeling and control of bilinear systems (BLS). BLS are linear but not jointly linear in state and control. In the first part of the thesis, a background to BLS and their applications to modeling and control is given. READ MORE
