A Systematic Review of Strong Gravitational Lens Modeling Software

Despite expanding research activity in gravitational lens modeling, there is no particular software which is considered a standard. Much of the gravitational lens modeling software is written by individual investigators for their own use. Some gravitational lens modeling software is freely available for download but is widely variable with regard to ease of use and quality of documentation. This review of 13 software packages was undertaken to provide a single source of information. Gravitational lens models are classified as parametric models or non-parametric models, and can be further divided into research and educational software. Software used in research includes the GRAVLENS package (with both gravlens and lensmodel), Lenstool, LensPerfect, glafic, PixeLens, SimpLens, Lensview, and GRALE. In this review, GravLensHD, G-Lens, Gravitational Lensing, lens and MOWGLI are categorized as educational programs that are useful for demonstrating various aspects of lensing. Each of the 13 software packages is reviewed with regard to software features (installation, documentation, files provided, etc.) and lensing features (type of model, input data, output data, etc.) as well as a brief review of studies where they have been used. Recent studies have demonstrated the utility of strong gravitational lensing data for mass mapping, and suggest increased use of these techniques in the future. Coupled with the advent of greatly improved imaging, new approaches to modeling of strong gravitational lens systems are needed. This is the first systematic review of strong gravitational lens modeling software, providing investigators with a starting point for future software development to further advance gravitational lens modeling research

07171 Abstracts Collection -- Visual Computing -- Convergence of Computer Graphics and Computer Vision

From 22.04. to 27.04.2007, the Dagstuhl Seminar 07171 ``Visual Computing - Convergence of Computer Graphics and Computer Vision\u27\u27 was held in the International Conference and Research Center (IBFI), Schloss Dagstuhl. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar as well as abstracts of seminar results and ideas are put together in this paper. The first section describes the seminar topics and goals in general. Links to extended abstracts or full papers are provided, if available

Community Engagement in Cultural Heritage A Digital Context

A series of case studies outlining the application of virtual reality and digital technologies for cultural heritage is presented in this article with an aim to examine the role for community engagement and SMEs in cultural heritage within a digital context. Digital technologies can be a repository and tool for telling local stories in relation to place and time on site and virtually off-site. In a series of case studies, tools and technologies for virtual reality experiences are outlined to identify the appropriate tools which can best facilitate this community engagement. In addition, community-based digital heritage initiatives will be discussed with reference to the Faro Convention. These technologies include applying BIM or GIS for historic structures involves initially data capture of the geometry and texture using laser scanning or digital photogrammetry, and then converting the digital survey data to solid Building Information Models (BIM). The process is described as Historic BIM or Historic GIS and, in this paper, several virtual reconstruction case studies of Irish Megalithic and Romanesque structures are presented

Faculty Research in Progress, 2018-2019

The production of scholarly research continues to be one of the primary missions of the ILR School. During a typical academic year, ILR faculty members published or had accepted for publication over 25 books, edited volumes, and monographs, 170 articles and chapters in edited volumes, numerous book reviews. In addition, a large number of manuscripts were submitted for publication, presented at professional association meetings, or circulated in working paper form. Our faculty\u27s research continues to find its way into the very best industrial relations, social science and statistics journal
