Double Layer Forces: the Role of Molecular Solvents

The dielectric continuum model has rightfully been and continues to be a major workhorse for theory and modelling in Surface and Colloid Chemistry. Due to the implicit description of water, entering only as a scaling constant for charge-charge interactions, one would not expect it to work for short distances. However, considerable evidence has been accumulated over the years which shows that t

Efficient use of finite element analysis in early design phases

The utilization of analytical/numerical techniques and methodologies within product development and design is seldom discussed in the literature. This leads to a loss of a holistic perspective on product development and design. The exclusion of analysis methods and techniques implies that their impact on the development/design procedures is considered negligible and is not regarded as a constituen

Vulnerability Analysis of Socio-Technical Systems: Addressing Railway System Vulnerabilities

The paper presents some ideas and modeling approaches that are feasible for the study of socio-technical systems. The emphasis in the paper is to discuss two approaches concerning modeling of social and technical systems, and how they can be integrated in order to assess the vulnerability of a socio-technical system. The Swedish railway system will serve as the example of a socio-technical system

High-Level Grafcet and Batch Control

The application of Grafcet to supervisory control applications with special emphasis on batch control is described. Grafchart, a Grafcet based G2 toolbox is presented. An industrial application where it is currently used on-line is described. High-Level Grafcahrt is an extension of Grafchart that is based on High-Level Petri nets and Object-Oriented Programming. It increases the parameterisation a
