We have developed a simple and robust system based on standard UNIX tools and frame library code to transfer and merge data from multiple gravitational wave detectors distributed worldwide. The transfer and merger take place with less than 20 min delay and the output frames are available for all participants. Presently VIRGO and LIGO participate in the exchange and only environmental data is sh...

In response to the charge “How can we best develop a systematic understanding of the intersection between human abilities, cartographic design decisions, and map use context? Can we predict what will work?” I argue for building a geovisual analytics observatory (GeO) to frame and support fundamental investigations based on empirical evidence of the who, what, how, when and why of human inferenc...

The architecture of Montage which delivers custom science grade astronomical images was presented at ADASS XII That architecture has been tested on MASS images computed on single processor Linux machines that hold all image data in memory This year we describe the design of a grid enabled version of Montage suitable for large scale pro cessing of the sky It exploits to the maximum the paralleli...

We describe the results of two near infrared (K-band) imaging surveys and a three color (JHK) survey of the vicinity of NGC 7538. The limiting magnitudes are K ≃ 16.5 and K ≃ 17.5 mag for the K-band surveys and K ≃ 15 mag for the JHK survey. We identify more than 2000 and 9000 near-infrared (NIR) sources on the images of the two Observations reported here were obtained at the MMT Observatory, a...

VOFilter is an XML based filter developed by the Chinese Virtual Observatory project to transform tabular data files from VOTable format into OpenDocument format. VOTable is an XML format defined for the exchange of tabular data in the context of the Virtual Observatory (VO). It is the first Proposed Recommendation defined by International Virtual Observatory Alliance, and has obtained wide sup...

In the course of its deliberations, the OTC noted that the NRAO R&D program has been reduced virtually to zero. ALMA development had become the prime new technical development for the observatory, but the development phase of ALMA is now over. It is particularly important, for the continuing health of the observatory and in order to maintain a modest degree of technical leadership, that at leas...

The ALMA software is a large collection of modules, which implements the functionality needed for the observatory day-to-day operations. The main ALMA software components include: array/antenna control/correlator, submission/processing of science proposals, telescope calibration and data archiving. The implementation of new features and improvements for every software subsystem must be coordina...

evaporation is one of the main parameters for the optimum operation of reservoirs, design of irrigation systems and scientific management of water resources. accurate estimation of the water evaporation level is crucial in any region especially in arid and semiarid regions. in this study, the feasibility of simulation of pan evaporation in maraghe station using the multiple regression models we...
