Question: Rensselaer Polytechnic Institute and Baylor University are both considered what kind of university?
Context: The Rensselaer RP-2 (for "Rensselaer Polytechnic design 2") is an American mid-wing, single-seat, glider that was designed by Steven J. Winckler and produced by the Rensselaer Polytechnic Institute of Troy, New York. Dr. Don Millard (born November 28, 1955) is a Program Director at the National Science Foundation (NSF).  Prior to joining NSF, he was a faculty member at Rensselaer Polytechnic Institute and the originator of the Mobile Studio Project.  In 1999 he started thinking about a way to enable students to perform experiments anytime, anyplace - specifically those that use an oscilloscope, function generator, digital control, and some form of power supply.  He started the Mobile Studio project by looking at commercially available solutions, which were prohibitively expensive; while choosing to involve students in bringing the project’s vision to reality.  Jason Coutermarsh, then a student at Rensselaer Polytechnic Institute (RPI), joined the project in the summer of 2004 and they developed a complete functional input/output board (IOBoard) hardware/software prototype.  With the support of several technology companies and the National Science Foundation, the Mobile Studio Project is now being utilized to enhance science, math, engineering and technology education around the world. The Rensselaer Polytechnic is the student-run newspaper of Rensselaer Polytechnic Institute.  It is published every Wednesday during the Institute's fall and spring academic calendars. The Rensselaer RP-1 (for Rensselaer Polytechnic design 1) is an American low-wing, single-seat, foot-launchable glider that was designed and produced by the Rensselaer Polytechnic Institute of Troy, New York. The Rensselaer Holiday Tournament was a college ice hockey tournament hosted by the Rensselaer Polytechnic Institute in Troy, New York.  The tournament was held annually for a duration of sixty years, from 1951 to 2010 at the Houston Field House.  It was, at various times, known as the Rensselaer Invitational, RPI Invitational, RPI Invitational Christmas Tournament, RPI Christmas Tournament, Rensselaer/Midland Bank Holiday Tournament, Rensselaer/HSBC Holiday Tournament and Rensselaer/Bank of America Holiday Tournament.  It was the oldest college hockey tournament in the United States, older than the Beanpot by a year.  Since the tournament has not been renewed since the 2010-2011 season, The Beanpot is now the oldest. George Bugliarello, (1928-February 2011) President Emeritus (having served as president from 1973 to 1994), Institute Professor and former chancellor (1994–2003) of the Polytechnic Institute of NYU (formerly Polytechnic University), was an engineer and educator with a broad background ranging from fluid mechanics to computer languages, the environment, biomedical engineering and science policy.  He held a Doctor of Science degree in engineering from the Massachusetts Institute of Technology, and was awarded honorary degrees from Carnegie-Mellon University, the University of Trieste, the Milwaukee School of Engineering, the Illinois Institute of Technology, Pace University, Trinity College, Rensselaer Polytechnic Institute, and the University of Minnesota. Rensselaer Polytechnic Institute ( ), or RPI, is a private research university and space-grant institution located in Troy, New York, with two additional campuses in Hartford and Groton, Connecticut. Tech Valley began as a marketing name for the eastern part of the U.S. state of New York, encompassing the Capital District and the Hudson Valley.  Originated in 1998 to promote the greater Albany area as a high-tech competitor to regions such as Silicon Valley and Boston, the moniker subsequently grew to represent the counties in New York between IBM's Westchester County plants in the south and the U.S.-Canadian border to the north, and has since evolved to constitute both the technologically-oriented metonym and the geographic territory comprising most of New York State north of New York City.  The area's high technology ecosystem is supported by technologically-focused academic institutions including Rensselaer Polytechnic Institute and the State University of New York Polytechnic Institute.  Tech Valley grew from encompassing 19 counties straddling both sides of the Adirondack Northway and the New York Thruway, and with heavy state taxpayer subsidy, has experienced significant growth in the computer hardware side of the high-technology industry, with great strides in the nanotechnology sector, digital electronics design, and water- and electricity-dependent integrated microchip circuit manufacturing, involving companies including IBM in Armonk and its Thomas J. Watson Research Center in Yorktown Heights, GlobalFoundries in Malta, and others.  As of 2015, venture capital investment in Tech Valley had grown to US$163 million.  Westchester County has developed a burgeoning biotechnology sector in the 21st century, with over US$1 billion in planned private investment as of 2016, earning the county the nickname "Biochester". The Rensselaer RP-3 (for "Rensselaer Polytechnic design 3") is an American mid-wing, T-tailed single-seat, glider that was designed by Brian E. Thompson and produced by the Rensselaer Polytechnic Institute of Troy, New York. Baylor University (BU) is a private Baptist university in Waco, Texas.  Chartered in 1845 by the last Congress of the Republic of Texas, it is the oldest continuously-operating university in Texas and one of the first educational institutions west of the Mississippi River in the United States.  Located on the banks of the Brazos River next to I-35, between the Dallas-Fort Worth Metroplex and Austin, the university's 1,000-acre campus is the largest Baptist university campus in the world.
