As tools for dynamic system modelling both conventional methods such as transfer function or state space representation and modern power flow based methods are available. The latter methods do not depend on energy domain, are able to preserve physical system structures, visualize power conversion or coupling or split, identify power losses or storage, run on conventional software and emphasize ...

This paper describes the continuous time modelling of the heat dynamics of a building. The considered building is a residential like test house divided into two test rooms with a water based central heating. Each test room is divided into thermal zones in order to describe both short and long term variations. Besides modelling the heat transfer between thermal zones, attention is put on modelli...

pomegranate is an important iranian-native fruit, with many varieties cultivated. although the volume of data on the importance of pomegranates in human nutrition has increased tremendously in the last years, the physical properties of the pomegranate fruit during fruit maturity have not yet been studied in detail. thus, the present study aimed to evaluate changes in physical characteristics of...

The objective of this paper is to illustrate the characteristics of Empirical Modelling (EM) in real world situations, and make a comparison with a traditional modelling paradigm. In order to observe activities within the real world domain, the wiimote is used as the mediating device between models and physical experiences. One of the limitations in modelling is building an artefact so that it ...

The cavability assessment of rock mass cavability and indicating the damage profile ahead of a cave-back is of great importance in the evaluation of a caving mine operation, which can influence all aspects of the mine operation. Due to the lack of access to the caved zones, our current knowledge about the damage profile in caved zones is very limited. Among the different approaches available, p...

The high failure rates of many business process change deployments are attributed to the inability to predict the outcome of the exercise without actually implementing the change in the physical environment. This restriction could be a result of over 80% of business process change projects adopting a static modelling technique in order to model their business processes. Static modelling enables...

Rapid robotic system development sets a demand for multi-disciplinary methods and tools to explore and compare design alternatives. In this paper, we present collaborative modelling that combines discrete-event models of controller software with continuous-time models of physical robot components. The presented co-modelling method utilized VDM for discrete-event and 20-sim for continuous-time m...

For the purposes of this paper, computer-aided physical modelling means a type of modelling in which a computer-aided approach is used, with the basic aim being to maintain the physical structure of a real system or its topology as much as possible in the model. Bond graphs represent a very efficient and traditional approach. However, new, objectoriented and multi-domain tools based on the Mode...

BACKGROUND Achieving health benefits while reducing greenhouse gas emissions from transport offers a potential policy win-win; the magnitude of potential benefits, however, is likely to vary. This study uses an Integrated Transport and Health Impact Modelling tool (ITHIM) to evaluate the health and environmental impacts of high walking and cycling transport scenarios for English and Welsh urban...
