Business processes have become essentials on internal operations within organizations. However, these require efficient storage mechanisms that allow their extraction and reuse. This paper proposes a method of storing and retrieval business process models, formally represented as graphs and whose search is based on control flow patterns.

Introduction. Vietnam’s largest economic centre, Ho Chi Minh City, is facing riverbank erosion, one of the main causes which runoff. In this study, flow velocity field Saigon River section analyzed in different time periods. Materials and methods. Data on discharge, water level, river network topography channel were collected to set up simulation models programmes MIKE 11 21. These are tools us...

Nowadays, developed and applied hydrology become very important thing in the life due to the wide verity advantages for the applications of this field. Hydraulic Structures such as crump weir are placed in channels to estimate or measure flow rate and flow control devices. In this study there is a new performance for crump weir which appears by adding opening holes in the model  of crump weir. ...

Ocean waters often show layered structures especially where exchange flow between two basins occurs. These structures are often attributed to processes such as double.diffusive convection, internal waves, turbulent modulated mixing. In this paper by examining the vertical structures of temperature, salinity and density, of the middle parts of Caspian Sea it is shown that such layered structure ...

Hierarchical Control Flow Graph Models deene a modeling paradigm for discrete event simulation modeling based upon hierarchical extensions to Control Flow Graph Models. Conceptually, models consist of a set of encapsulated, concurrently operating model components that interact solely via message passing. The primary objectives of Hierarchical Control Flow Graph Models are: (1) to facilitate mod...

AbsrructAs the number of available multiprocessors increases, so does the importance of providing software support for these systems, including parallel compilers. Data flow analysis, an important component of software tools, may be computed many times during the compilation of a program, especially when compiling for a multiprocessor. Although converting a sequential data flow algorithm to a p...

The transition from stratified to intermittent air-water two-phase flow was investigated experimentally, by visualization and pressure drop signals analyses, in a 30 mm ID pipe. flow’s onset found be mainly dependent on the liquid superficial velocity pipe diameter. Plug flow, Less Aerated Slug (LAS) or Highly (HAS) flows could obtained gas grounds. available models, compared experiments, not p...

Accurate estimate of flood flows at selected return periods is a fundamental step in flood control and design of hydraulic structures. Due to the inadequacy or unavailability of flood flow records in several western catchments of Iran, traditional regional flood frequency methods lead to remarkable estimate errors, particularly for long return periods. In this research, discriminant analysis is...

flow passing through lateral intakes and channel junctions is turbulent. sediment flow and bed forms areaffected by these flow patterns and vice versa. in this research, a laboratory study was carried out toexplore a possible method for sediment control for a set of submerged vanes and a single spur dikesimultaneously. since a larger portion of the near-bed flow was diverted, the intake receive...
