In this study, we explore the relationships among group size, the extent of interactions with other groups, and group performance in a stochastic environment. We have developed a modeling framework which allows the connections among the individual members constituting a group and the connections...

Social foraging differs from individual foraging because it alters both resource availability and the forager's behavior. We examined responses of starlings to the presence of conspecifics by manipulating foraging-group density experimentally, while ensuring that each subject's foraging...

Group foraging allows for individuals to exploit the food discoveries of other group members. If searching for food and searching for exploitation opportunities within a group are mutually exclusive alternatives, the decision to use one or the other is modeled as a producer-scrounger game...

This study examines the role of the parameterization of convection, planetary boundary layer (PBL) and explicit moisture processes on tropical cyclone intensification. A high-resolution mesoscale model, National Center for Atmospheric Research (NCAR) model MM5, with two interactive nested...

On the day of the Tohoku-Pacific Ocean Earthquake (2011), all rail services in the Tokyo Metropolitan area were paralyzed, amid substantial confusion. Consequently, over 3 million persons were unable to return home on that day. Some, unable to contact their families, felt uneasy and set out to...

Systems view thinking and holistic urban water cycle concepts are increasingly called upon for integrated analysis of urban water systems to mitigate water stress in large urban agglomerations. However, integrated analysis is frequently not applied due to the inherent complexity, limitations in...

The research focused on the potentialities of the package Matlab Neural Networks to build predictive models of economic and social processes.

The article substantiates expediency of use of the multi-agent simulation modelling in the study of dynamics of complex economic systems. It shows a possibility to use cellular automata in construction of simulation economic models, particularly models of consumers' behaviour, in principle. It...
