Prototyping the Data Access Layer of the Integrated Hydrologic Forecast System
نویسنده
چکیده
The Hydrologic Research Laboratory of the National Weather Service Office of Hydrology is developing its next generation of software for the conduct of the National Weather Service Hydrologic Services Program. The Integrated Hydrologic Forecast System (IHFS) project is currently focused on developing and prototyping software and data architecture components of the system. The prototype involves an element of operational functionality that exercises the data access layer as well as an object oriented approach to analysis and design. The prototype is designed for testing as an integrated component of the current operational forecast system. The IHFS software architecture is highly modular and considers a gradual and planned transition from current operational software to the new system. This paper presents progress in developing a prototype of the data access layer and the logical data model. The rationale for this effort is described and details of the data access architecture and the data access prototype are presented.

Adaptive Spectral Separation Two Layer Coding with Error Concealment for Cell Loss Resilience
This paper addresses the issue of cell loss and its consequent effect on video quality in a packet video system, and examines possible compensative measures. In the system's enconder, adaptive spectral separation is used to develop a two-layer coding scheme comprising a high priority layer to carry essential video data and a low priority layer with data to enhance the video image. A two-step er...

متن کاملAccess control in ultra-large-scale systems using a data-centric middleware
The primary characteristic of an Ultra-Large-Scale (ULS) system is ultra-large size on any related dimension. A ULS system is generally considered as a system-of-systems with heterogeneous nodes and autonomous domains. As the size of a system-of-systems grows, and interoperability demand between sub-systems is increased, achieving more scalable and dynamic access control system becomes an im...
متن کاملA tightly coupled GIS and distributed hydrologic modeling framework
Distributed, physics-based hydrologic models require spatially explicit specification of parameters related to climate, geology, land-cover, soil, and topography. Extracting these parameters from national geodatabases requires intensive data processing. Furthermore, mapping these parameters to model mesh elements necessitates development of data access tools that can handle both spatial and tem...
متن کاملAnalysis and Forecast of Mining Accidents in Pakistan
In the mining sector, the barrier to obtain an efficient safety management system is the unavailability of future information regarding the accidents. This paper aims to use the auto-regressive integrated moving average (ARIMA) model, for the first time, to evaluate the underlying causes that affect the safety management system corresponding to the number of accidents and fatalities in the surf...
