Small bins are used to conduct cooling and drying experiments on wheat, barley and peas. Seven conceptual models were tried. They consider different ways in which water may leave the grain. A new equation has been developed to take the hysteresis phenomenon into account. The loss of energy...

The variable fluorescence in the fast phase of chlorophyll a fluorescence induction phenomenon is closely related to the electron transport in photosystem II (PS II) of plants. We present here two theoretical models that simulate successfully the experimental data on the O-J-I-P fluorescence...

A qualitative analysis is developed for continuous-time neural networks subjected to random pure structural variations. Simple algebraic conditions are established for both structural exponential stability of x = 0 of the neural network and for estimates of its domain of attraction. Bounds on...

The paper considers the problem of training on-line a neural network model of non-linear heater battery for implementation in a model-based control scheme. A stable learning scheme is proposed which reduces parameter drift due to process-model mismatch in radial basis function (RBF) networks. A...

In modelling complex stochastic systems graphical association models provide a convenient framework. With graphical models the overall structure of association among variables is described in terms of conditional independence, and this structure can be represented graphically. Statistical...

A general comparison with regard to speed and size of digital neural hardware on different levels of parallelism results in the design of a fully parallel architecture based on a bit-serial neural hardware model with a new quadratic squashing function. This nonlinear squashing function is well...

The cytoskeleton consists of networks of protein polymers which structurally and dynamically organize interiors of living cells. Microtubules are the best characterized and perhaps most fundamental filamentous subcellular structures known to date. Microtubules exhibit a fascinating array of...

The nature of dynamics, as we know it, is hierarchical. Thus — it is argued — consciousness emerges from the hierarchical structure of the brain in the same way that life emerges from the hierarchical structure of the body.

A mathematical model was developed to describe the heat transfer during the sterilisation of conduction heating foods inside three dimensional two division rectangular packs. The model uses a standard explicit finite differences method with non-capacitance surface nodes and simulates different...
