What is Polaris?
Polaris is a resource for Flagler College students, a self-instructional tutorial to teach them basic library and research skills. It covers the research process from initial topic selection to citation styles and the issue of plagiarism. There is a link to Polaris on the Proctor Library home page or it can be accessed directly from http://www.flagler.edu/library/polaris/choice.html.
Polaris is a dynamic group of adults filling a valuable role in the success of Fernbank Museum. Volunteering for the Museum provides the opportunity to interact with the public in a fun and educational environment. Through your association with Polaris, you are lending your support to one of Atlanta’s top cultural institutions.
Polaris, also known as the North Star because of its proximity to the celestial pole, is the brightest star in the constellation Ursa Minor, the Little Bear or the Little Dipper. Polaris can be found by extending an imaginary line from the two farthest-right stars in the Big Dipper “upwards” from the “ladle” of the dipper, and locating a very bright star immediately on that line. Polaris was historically used by slaves in America’s South attempting to escape to the North through the Underground Railroad. Hence the folk song, “Follow the Drinking Gourd”. “Drinking gourd” refers to the Big Dipper. Polaris, like many stars, is part of a trinary system that includes Polaris A, Polaris Ab, and Polaris B. The whole system is located between 400 and 460 light years from the Earth. The name of Polaris derives, of course, from its position as a polar star. Polaris is a giant star containing between five and six solar masses of material. It is 60 solar radii in diameter and has a luminosity 2200
POLaRIS stands for Performance, Organization, Learning and Real-Time Improvement System. IRETA developed this performance improvement core model over a number of years, recognizing that existing models were not adequate to grow into system-wide and sustainable change mechanism. Implementation of POLaRIS creates an environment where front-line practitioners are invested in and direct the change process in conjunction with organizational leadership by creating learning communities. The focus is on the process not the person — why did the process fail and how do we fix it — creating a “blame-free” culture that encourages input from bottom up as well as top down. In this continuous learning environment, problems are spotted sooner and changed in real time. Customer feedback is incorporated immediately. Data collection is only one aspect of this larger change initiative. IRETAs unique approach combines leadership, principles from the Toyota Production System (TPS), Aloca Business System a
Polaris is a source to source transforming compiler, originally developed at UIUC, intended to parallelize programs written as conventional, sequential algorithms. Polaris is essentially a driver routine which scans a FORTRAN 77 program and converts it into an Abstract Syntax Tree (AST). Then, various passes are called by the driver on the AST. Each pass attempts to optimize the program via specific methods, such as constant propagation, reduction recognition, etc.. The driver program completes its task by printing the program What is MiniPolaris? MiniPolaris is a version of Polaris with only the most fundamental passes.The source program is read, parsed, and converted to an AST. The user will then provide custom passes to extract information or make transformations on the statements. After the custom passes are executed, the driver program outputs the resulting code. Getting started To get started with MiniPolaris the first thing to do is to actually setup the MiniPolaris environment.
