Identifying authorship correctly and efficiently is a difficult problem when the literature is abundant, but poorly recorded. Homonyms are tedious to differentiate. This paper describes how the field of economics has organized itself with respect to author identification. We describe the RePEc project with a special emphasis on the RePEc Author Service. We then discuss how the concept is curren...

After arXiv.org, the RePEc economics library offers the second-largest source of freely downloadable scientific preprints in the world. RePEc has a different business model and a different content coverage than arXiv.org. This paper addresses both

Introduction: one of the minimally invasive methods of treatmenting liver malignancies is Radiofrequency Ablation (RFA) which can be applied to primary or secondary tumors. Nevertheless, the disease recurrence is probable after RFA application partially due to the inadequate capability of temperature monitoring of the target tissue and visualizing the thermal damage. The goal of this work was t...

Fluorescent Whitening Agents (FWA), dyes and pigmented inks are used extensively in the paper industry to enhance the appearance and optical performance of coated and uncoated papers. There are several different systems in use for the description and specification of color and optical properties of paper, using colorimeters, spectrophotometers and brightness meters. CIE and TAPPI are the most c...

We have extended the work of Papers I and II this series to determine at higher spatial resolution properties embedded Orion-S Molecular Cloud that lies within ionized cavity Orion Nebula thin layer between observer. This was done using existing new [NII](658.3 nm) [OIII] (500.7 spectra map central region (the Huygens Region). However, it remains unclear how surface brightness on a foreground N...

We present B, R, and Hα imaging data of 19 large disk galaxies whose properties are intermediate between classical low surface brightness galaxies and ordinary high surface brightness galaxies. We use data taken from the Lowell 1.8m Perkins telescope to determine the galaxies’ overall morphology, color, and star formation properties. Morphologically, the galaxies range from Sb through Irr and i...

In this paper, a fast motion compensation algorithm is proposed that improves coding efficiency for video sequences with brightness variations. We also propose a cross entropy measure between histograms of two frames to detect brightness variations. The framewise brightness variation parameters, a multiplier and an offset field for image intensity, are estimated and compensated. Simulation resu...
