Green roofs have multiple environmental benefits, such as saving energy, improving air quality, mitigating noise, providing habitat, beautifying the landscape, and improving urban hydrology. Among the environmental benefits of green roofs, improving runoff quality is a controversial issue. Substrate and plant litter may be transported with green roof runoff, which would increase the risk of urb...

The extensive eastern boundary of Everglades National Park (ENP) in south Florida (USA) is subject to one of the most expensive and ambitious environmental restoration projects in history. Understanding and predicting the water quality interactions between the shallow aquifer and surface water is a key component in meeting current environmental regulations and fine-tuning ENP wetland restoratio...

Ray tracing is a frequently used method for acoustic simulations, valued its calculation speed and ease of use. Although it fast, there are no fully ray tracing-based real-time simulation methods or engines. Under restrictions, simulations lose precision the variance inherent in random has too much impact on outcome. In this paper, an algorithm called iterative presented that reduces negative e...

abstract: water quality of dam storage is highly affected by upstream environment and basin. regarding other conducted studies, there exist various reasons such as some studies and general monitoring of dams which cause some main problems including salinity, chemical and microbial pollution eutrophication, and sedimentation. chame-gardalan storage dam in ilam province is one of the storages whi...

The New Zealand dairy industry faces political and commercial pressure to improve its environmental performance while maintaining commercial competitiveness in a global marketplace. In response to such pressures, the industry has taken some steps to improve the environmental management practices of dairy farmers. Despite significant effort, however, the dairy sector remains highly influenced by...

Program comprehension is an emerging interest area within the software engineering field. Software engineering itself is concerned with improving the productivity of the software development process and the quality of the systems it produces. However, as currently practiced, the majority of the software development effort is spent on maintaining existing systems rather than developing new ones....

CASE (Computer Aided Software Engineering) tools are believed to have played a critical role in improving software productivity and quality by assisting tasks in software development processes since 1970s. Several parametric software cost models adopt “use of software tools” as one of the environmental factors that affects software development productivity. Several software cost models assess t...
