arguably, the natural gas transmission pipeline infrastructure in iran represents one of the largest andmost complex mechanical systems in the world. the optimization of large gas trunk lines known asigat results in reduced fuel consumption or higher capability and improves pipeline operation. in thecurrent study, a single-objective optimization was conducted for khormoj compressor station on t...

Astronomical photometry is the science of measuring the flux of a celestial object. Since its introduction in the 1970s the CCD has been the principle method of measuring flux to calculate the apparent magnitude of an object. Each CCD image taken must go through a process of cleaning and calibration prior to its use. As the number of research telescopes increases the overall computing resources...

We describe the processing of PHANGS–ALMA survey and present pipeline, a public software package that processes calibrated interferometric total power data into science-ready products. is large, high-resolution CO(2–1) emission from nearby galaxies. The observations combine ALMA's main 12 m array, 7 observations, use mosaics dozens to hundreds individual pointings. u − v data, imaging deconvolu...

The development of an image processing pipeline for each new camera design can be time-consuming. To speed camera development, we developed a method named L (Local, Linear, Learned) that automatically creates an image processing pipeline for any design. In this paper, we describe how we used the L method to design and implement an image processing pipeline for a prototype camera with five color...

The Tianlai project is a 21cm intensity mapping experiment aimed at detecting dark energy by measuring the baryon acoustic oscillation (BAO) features in large scale structure power spectrum. This provides an opportunity to test data processing methods for cosmological signal extraction, which still great challenge current radio astronomy research. much weaker than foregrounds and easily affecte...

It is in the interest of any gas company to maintain the value of its pipelines and to protect them effectively against damage caused by third parties. As a result of global progress in high-resolution remote sensing and image processing technology, it is now possible to design natural gas pipeline monitoring systems with remote sensors and context-oriented image processing software. Recent dev...

Pre-processing MRI scans prior to performing volumetric analyses is common practice in MRI studies. As pre-processing steps adjust the voxel intensities, the space in which the scan exists, and the amount of data in the scan, it is possible that the steps have an effect on the volumetric output. To date, studies have compared between and not within pipelines, and so the impact of each step is u...
