First principle modeling of chemical processes very often leads to a mixed system of partial differential equations (PDEs) and differential algebraic equations (DAEs) which must be preprocessed for use in standard DAE numerical simulation or optimization tools. This contribution presents the...

Current research about determinants of accounting information disclosed by companies suffers from various limits liked with quantitative tools suggested by positivist methodologies. Statistical validation of disclosure determinants hides the firm communication process and its dynamic. To...

In recent years, human activities have begun to seriously influence local and global environments. Under the circumstances, Life Cycle Assessment (LCA) is expected to be a powerful tool in evaluating impacts on environments. However, LCA is not yet established methodologically or formulated...

The high cell density cultivation (HCDC) of genetically modified microorganisms, e.g. E. coli, with dry weight larger than 100 g⧸l, requires fed-batch processing with aid of a controlled specific growth rate μ. A general mathematical model of HCDC as well as different methods to control μ is...
