An attempt to explore global trends in environmental monitoring using numerous ways based on different techniques is an exercise in the right direction. This is expedient, given the recent overwhelming growing rate of environmental pollution of advertisement graphical bills worldwide. Posting of advertisement graphical bills constitutes one of the biggest threats to man and his environment as it now appears and as we live in an age of growing sensitivity to environmental cleanliness. Pollution of the Nigerian cities through advertisement bills assumes the general term of outdoor advertising ranging from hand-printed signs, posters, painted bulletins and spectaculars. However this paper discusses the trends of posting graphic advertisement bills in Nigerian cities. Its impact on aesthetics, as well as the pollution problems associated with the urban development. The study areas are Abuja, Akure, Ibadan and Lagos. In order to ensure that each unit of the population is represented, random sampling technique was used to get the necessary information from the samples. The findings emphasize the importance of strict control and market regulations in posting of advertisement bill in built environment and eradication of pollution of the environment.展开更多

The SGDMS is a distributed management system proposed using Multi-Agent System (MAS) technology. This system can optimise the distribution of renewable energy while minimizing electricity bills for consumers. The entire system was developed using Java with the extension of JADE which is an IEEE FIPA compliant multi-agent system platform. This decentralised platform allows agents to interact and communicate using energy sources from different sectors and control them intelligently to minimise the cost of electricity for the consumers. Simulation studies were carried out on the proposed system to show its potential for providing solutions through intelligent distribution techniques and how it influences the cost of electricity.展开更多
