Bike sharing systems (BSSs) offer a mobility service whereby public bikes, located at different stations across an urban area, are available for shared use. An important point is that the distribution of rides between stations is not uniformly distributed and certain stations fill up or empty over time. These empty and full stations lead to demand for bikes and return boxes that cannot be fulfi...

The prerequisite of maintaining an efficient and safe mining operation is the proper design of a mine by considering all aspects. The first step in a coal mine design is a realistic geometrical modelling of the coal seam(s). The structural features such as faults and folding must be reliably implemented in 3D seam models. Upon having a consistent seam model, the attributes such as calorific val...

abstract purpose-the purpose of this paper is to review a sample of the literature relating to interpretive structural modelling (ism) and its deployment for modelling purposes in the area of supply chain management (scm). design/methodology/approach- the literature is examined from the three perspectives. first, concept of ism and examines ism as modelling technique. second, use of ism by the ...

Pollution has become a very serious threat to our environment. Monitoring pollution is the rst step toward planning to save the environment. The use of dierential equations, monitoring pollution has become possible. In this paper, a Ritz-collocation method is introduced to solve non-linear oscillatory systems such as modelling the pollution of a system of lakes. The method is based upon Bernoul...

A model has been used to simulate potassium (K) uptake by wheat in a pot culture experiment. Three soils from India, namely Alfisol, Inceptisol and Vertisol, were differentially K exhausted by Sudan grass (Surghum vulgare var. Sudanensis) for a period of 280 days and were used to simulate potassium uptake by wheat (Triticum aestivum) and also to predict the amounts of K released or fixed during...

in the present study, a new modelling technique was developed for the modelling and analysis of hyperchaotic systems using an expert system based on wavelet decompositions and the adaptive neuro-fuzzy inference system (anfis). the success and superior properties of this new expert system were shown by applying the hyperchaotic chen system which is a hyperchaotic system. the obtained expert s...

the excess accumulation of water in lung interstitial or alveolar is called pulmonary edema which is caused by factors that upset the normal starling balance in micro-circulation. pulmonary edema disturbs the alveolar gas exchanges which are normally regulated by the respiratory system. mathematical modelling of pulmonary edema may help to predict the lung conditions and the mechanisms involved...

The thesis of this work is that the realism afforded by current computer graphical methods for modelling and animating fire can be improved. To prove this, a physically-based modelling technique and a procedural texture modelling technique will be combined to model a real-time fire. The aim is improve the realism and visual quality of real-time animated fire. This project specifically will focu...
