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...

We report a series of new surface reconstructions on BaTiO3(001) as a function of environmental conditions, determined via scanning tunneling microscopy and low energy electron diffraction. Using density functional theory calculations and thermodynamic modeling, we construct a surface phase diagram and determine the atomic structures of the thermodynamically stable phases. Excellent agreement i...

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.

An important class of scientific and engineering workflows, e.g. those used for uncertainty quantification, design optimization and parametric studies, naturally map onto the Many-Task Computing (MTC) paradigm. However, what distinguishes these workloads is a unique combination of dynamically changing resource requirements and very large computational and throughput demands. Such workflows can ...

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....
