The process of building system dynamics models ranges from linear iterative phases to the circular iterative phases. However, while all these process designs are well known and explicit to system dynamics modellers, they are not comprehensive for participative modelling involving clients/participants without prior modelling knowledge. This paper presents a detailed modelling process design of s...
Lipid formulations can improve the bioavailability of drugs that have low aqueous solubility. A variety of chemical compounds, including triglyceride oils (lipids), fatty acid esters and surfactants, can be included in lipid formulations. This heterogeneity makes spectroscopic study of the in ternal structure of formulation difficult. Understanding of lipid formulations at a molecular level wil...
Multidimensional modelling of open-cycle process of OM355 engine was developed. Calculations for computational mesh were carried out. The results of the model were validated by experimentally measured in-cylinder pressure and the good agreement between calculations and measurements approved the trustworthy of numerical code. Results included pressure, temperature, emission and Rate of heat rel...
The inherent inconsistency in identifying the phase field crystal Theory with material mass and, simultaneously, distortion is discussed. In its current implementation, elastic relaxation occurs on a diffusive time scale through dissipative permeation mode. very same that included solid elasticity drives motion, resulting non physical of crystal. We present two alternative theories to remedy th...
Advances in the field of quantum sensing mean that magnetic field sensors, operating at room temperature, are now able to achieve sensitivity similar to that of cryogenically cooled devices (SQUIDs). This means that room temperature magnetoencephalography (MEG), with a greatly increased flexibility of sensor placement can now be considered. Further, these new sensors can be placed directly on t...
Phase-field models have become popular in recent years to describe a host of free-boundary problems in various areas of research. The key point of the phase-field approach is that surfaces and interfaces are implicitly described by continuous scalar fields that take constant values in the bulk phases and vary continuously but steeply across a diffuse front. In the present contribution, a distin...
