Various methods for controlling manufacturing systems have been proposed, but until now the problem could not be considered as being solved. This may be due to the lack of a sound mathematical foundation. Therefore, an algebraic modelling method to describe manufacturing systems is developed. The result of this system modelling is a state equation which can be used for the design of closed loop...

Our goal is to provide a kernel to allow interactive and accurate modelling of volume objects. As a first step, we present a data structure for three-dimensional fields C continuous in the modelling space. Regular grids storing the field values discretely are combined with a triquadratic approximation filter to define volume objects. This association of a grid and an approximation/interpolation...

In recursive linear models, the multivariate normal joint distribution of all variables exhibits a dependence structure induced by recursive systems of linear structural equations. Such models appear in particular in seemingly unrelated regressions, structural equation modelling, simultaneous equation systems, and in Gaussian graphical modelling. We show that recursive linear models that are ‘b...

Pedestrian facilities are aimed at providing proper walking infrastructure and environment to promote in cities needs serve the desired requirements of users. It is important assess level service (LOS) provided by such facilities. Various guidelines available for assessing LOS sidewalks, midblock crossings pedestrians along carriageway. However, factors considered assessment diverse no single g...

Within a microscopic approach the structure of Neutron Stars is usually studied by modelling the homogeneous nuclear matter of the core by a suitable Equation of State, based on a manybody theory, and the crust by a functional based on a more phenomenological approach. We present the first calculation of Neutron Star overall structure by adopting for the core an Equation of State derived from t...

the impact assessment method seeks to bring about a more ecologically, socio-culturally and economically sustainable and equitable environment. determining the main factors affecting the attitudes of stakeholders is crucial for understanding the impacts of development plans. this approach helps planners and decision makers to identify the values and traits of stakeholders and accelerate the dif...

Modelling the Brand Equity is a must for any corporate. How much brand worth? Brands dijfer in their power and value market place. estimated of premium customers are willing to pay using branded product compared an unbranded product. intangible assets it difficult measure directly. Brands, however, do not necessarily last forever Hence important that they monitored over period time. Structural ...

The partial differential equation has been vastly applied to analyzing the problems in the life sciences. However, these types of partial differential equation models are mostly deterministic. As we know, the real life is full of uncertain factors, hence the above deterministic partial differential equations are not enough to handle the problems with uncertain noises. For modelling these proble...
