development of water resources projects are recognized as a basis of the development planning in the water resources sector. in addition to the quality of output results, following the schedule , continuous documentation and evaluation during the project is the one of the major challenges. in order to improve water study framework with high quality and scheduling and reduce the study process, t...

Jorge E. Bardina Intelligent Systems Division NASA Ames Research Center Moffett Field, CA 94035, U.S.A. The simulation and modeling of launch operations is based on a representation of the organization of the operations suitable to experiment of the physical, procedural, software, hardware and psychological aspects of space flight operations. The virtual test bed consists of a weather expert sy...

We describe a new resource for targeted insertional mutagenesis in Arabidopsis using a maize (Zea mays) Activator/Dissociation (Ds) two-element system. The two components of the system, T-DNA vectors carrying a Ds launch pad and a stable Activator transposase source, were designed to simplify selection of transposition events and maximize their usefulness. Because Ds elements preferentially tra...

The objective of the Air Force’s Launch Programs System Program Office (SPO) was to develop and improve the acquisition process. Realizing that the cycle time for contract proposals was an area that needed reform, the Launch Programs SPO set out to reengineer the process. By developing a contractor and government integrated product team that worked together to define a new streamlined approach ...

Question: This study analyzes the effect of pharmaceutical price regulation on the launch of new drugs. Obtaining regulatory approval for a price may entail administrative delay. In addition, since a low price in one market may “spill-over” to other markets, through parallel trade and external referencing, manufacturers may rationally prefer longer delay or non-launch of drugs to accepting a re...

abstract—today, botnets have become a serious threat to enterprise networks. by creation of network of bots, they launch several attacks, distributed denial of service attacks (ddos) on networks is a sample of such attacks. such attacks with the occupation of system resources, have proven to be an effective method of denying network services. botnets that launch http packet flood attacks agains...

This study examines how consumers’ interest in a new movie develops around paid and earned media in pre-launch periods, how this interest impacts opening-week revenue, and how postlaunch revenue of a movie is influenced by advertising and various earned media. The prelaunch, opening-week and post-launch worlds are structurally different and we therefore develop three separate models, two multip...

This paper offers a critical commentary on the launch process for a large commercial aircraft (LCA). Using the Boeing 7e7 as an example, we argue that the contemporary launch process bears little resemblance to previous practices. Specifically, the launch process involves both domestic and foreign subsidies because US production is now organized under a ‘systems integration’ basis. Under system...
