Towards Formula Concept Discovery and Recognition

Author(s)
Howard S. Cohl, Philipp Scharpf, Moritz Schubotz, Bela Gipp
Citation-based Information Retrieval (IR) methods for scientific documents have proven to be effective in academic disciplines that use many references. In

On a generalization of the Rogers generating function

Author(s)
Howard S. Cohl, Roberto Costas-Santos, Tanay Wakhare
We derive a generalized Rogers generating function and corresponding definite integral, for the continuous q-ultraspherical polynomials by applying its

Some generating functions for q-polynomials

Author(s)
Howard S. Cohl, Roberto Costas-Santos, Tanay Wakhare
We obtain $q$-analogues of the Sylvester, Cesaro, Pasternack, and Bateman polynomials. We also derive generating functions for these polynomials.

MathTools: An Open API for Convenient MathML Handling

Author(s)
Howard S. Cohl, Andre Greiner Petter, Moritz Schubotz, Bela Gipp
Mathematical formulae carry complex and essential semantic in- formation in a variety of formats. Accessing this information with different sys- tems requires a

VMEXT: A Visualization Tool for Mathematical Expression Trees

Author(s)
Moritz Schubotz, Howard S. Cohl, Bela Gipp, Norman Meuschke, Thomas Hepp
Mathematical expressions can be represented as a tree consisting of terminal symbols, such as identifiers or numbers (leaf nodes), and functions or operators

Sampling Architectures for Ultra-Wideband Signals

Author(s)
Howard S. Cohl, Steve Casey
Ultra-wideband (UWB) signal processing is a technology with many features that could develop into advances in communication and information technology. The

Getting the units right

Author(s)
Howard S. Cohl, Moritz A. Schubotz, David Veenhuis
To understand applied physics, and physical formulae in particular, the investigation of identifier units is beneficial. However, normally the units are not

Report from Open Problems Session at OPSFA-13

Author(s)
Howard S. Cohl, Richard Askey, Rick Beatson, Charles Dunkl, Christoph Koutschan, Sheehan Olver, Yuan Xu, Wolfgang Zu Castell, Wadim Zudilin, Ted Chihara
We provide the open problems presented at OPSFA-13, Gaithersburg, Maryland, June 4, 2015. Howard Cohl, National Institute of Standards and Technology, has

Some dual definite integrals for Bessel functions

Author(s)
Howard S. Cohl, Rebekah M. Palmer, Sean Nair
Based on known definite integrals of Bessel functions of the first kind, we obtain exact solutions to unknown definite integrals using the method of integral

Digital Repository of Mathematical Formulae KLS Seeding Project

Author(s)
Howard S. Cohl, Marjorie A. McClain, Bonita V. Saunders, Moritz Schubotz, Cherry Y. Zou, Alex A. Danoff, Azeem S. Mohammed
One initial goal for the DRMF is to seed our digital compendium with fundamental orthogonal polynomial formulae. We have received permission from Springer
