Developing an understanding of Industrial Ecology (IE) and implementing Design for Environment (DfE) requires a sophisticated understanding of waste streams and the processes and products that generate them. Data deficiencies and methodological issues complicate this necessary effort. Allen demonstrates how data on industrial and municipal wastes can be used to assess the potential utility of w...

The influence of a strong low-level temperature inversion on the occurrence of lee waves, rotors and hydraulic jumps has been investigated using high resolution numerical model simulations. The aim of the work is to develop tools for forecasting hazardous winds downstream of mountains. Two-dimensional simulations were conducted for a range of inversion heights and strengths and a fixed hill sha...

Data Flow Diagrams and Use Cases are two popular methodologies in teaching as well as in practice. We recently used both methodologies in teaching four sections of our required Systems Analysis course. Questionnaire results indicate that students prefer Data Flow Diagrams.

Unified Modeling Language (UML) is the Object Management Group (OMG) standard notation for object-oriented modeling. UML activity diagram (AD) are widely used to workflow and system flow in system analysis. However, activity diagram lacks support for simulation, dynamic semantics limits and verifiability capabilities. APN are a popular technique for modeling the control flow dimension of workfl...

Sarvak formation, with the middle cretaceous (Cenomanian) age, is one of the stratigraphic units of the Bangestan group in the southern Iran. The carbonate rocks of this formation form the reservoir rock in the study field. Generally, Sarvak formation is subdivided into three members including Mishrif, Khatiyah, and Maddud in the Persian Gulf, and the average thickness of the reservoir unit (i....

Background& objectives: Zarrinehrud River is one of the most important permanent and water-rich rivers in West Azerbaijan province located in the catchment area of Lake Urmia. In this study, to evaluate the quality of the Zarrinehrud River, with a length of 57.5 kilometers from the outlet of Noroozlou to the drainage dam to the Lake Urmia, QUAL2K computer simulation model was used. Methods: Th...
