Although large developed System dynamics model can be applied on different ecological system in this paper it is applied on Kastela region in Croatia. The Computer Simulation Sub model of The Ecological Regional Subsystem of the "KASTELA BAY" is an extra relevant submodel of The System Dynamics Computer Simulation Model of the “KASTELA BAY” which has been developed with the help of System Dynam...

nowadays, electricity is one of the most significant infrastructures required for economic development of countries. hence, predicting electricity demand is very important especially in industry as a major electricity-consuming sector. the majority of studies under the subject of electricity demand have been performed by econometrics and it is not possible to investigate the effect of different...

The paper presents an agent-based model for the explicit representation of groups of pedestrians in a crowd. The model is the result of a multidisciplinary research (CRYSTALS project) where multicultural dynamics and spatial and sociocultural relationships among individuals are considered as first class elements for the simulation of crowd of pilgrims taking to the annual pilgrimage towards Mak...

Joint flexibility is a very important factor to consider in the controller design for robot manipulators if high performance is expected. Most of the research works on control of flexible-joint robots in literature have ignored the actuator dynamics to avoid complexity in controller design. The problem of designing nonlinear controller for a class of single-link flexible-joint robot manipulator...

the complete 3d nonlinear dynamic problem of extensible, flexible risers conveying fluid is considered. for describing the dynamics of the system, the newtonian derivation procedure is followed. the velocity field inside the pipe formulated using hydrostatic and bernoulli equations. the hydrodynamic effects of external fluids are taken into consideration through the nonlinear drag forces in var...

in this paper, the important formation control problem of nonholonomic wheeled mobile robots is investigated via a leader-follower strategy. to this end, the dynamics model of the considered wheeled mobile robot is derived using lagrange equations of motion. then, using adams multi-body simulation software, the obtained dynamics of the wheeled system in matlab software is verified. after that, ...

The paper reports the results of an empirical investigation on pedestrian dynamics in presence of groups. We consider a real world scenario in which an analysis of the impact of groups on the overall observed system dynamics was performed through manual counting and tracking. The simulation results are compared to empirical data and they show that the adopted model is able to produce quantitati...

Climate is a complex system which is changing mainly due to the increase of greenhouse gases. Because of the importance of climate change and the effects it can have on water resources, in recent years, this topic has been taken into consideration for different basins on Earth. The objective of this study is to investigate the effects of climate change and forecasting meteorological variables o...

Some large system dynamics models drive simulator interfaces used for teaching; this is the case of the MacroLab model. Such a model may be useful for making students with basic instruction in system dynamics explore the economy as a dynamic system, allowing for diverse inquiry itineraries. The question is if different exploration itineraries yield sufficiently similar learning outcomes. This h...
