Tethers Unlimited expands to fulfill additive manufacturing orders

“At this point we are in a chicken-and-egg situation, so we are trying to work incrementally toward those goals,” Hoyt said in October at the Additive Aerospace Summit in Los Angeles. NASA is paying the company to build Refabricator, a machine to
One-step volumetric additive manufacturing of complex polymer structures

Two limitations of additive manufacturing methods that arise from layer-based fabrication are slow speed and geometric constraints (which include poor surface quality). Both limitations are overcome in the work reported here, introducing a new
High-brilliance X-ray sheds light on additive manufacturing process

The additive manufacturing process involves depositing thin layers of composite materials on top of each other. Air Force Research Laboratory Composite Materials and Processing team researchers used the ultra-bright X-ray at the National Synchrotron
Brewing Up A Better Gasoline Additive With Beer?

The chemistry of gasoline is not as simple as you'd think. In the absence of additives, your engine will knock itself into oblivion (See: Octane Rating And Lead: Explaining The Chemistry Of Gasoline). Over the years, a number of anti-knocking additives Additive Combinatorics

Additive combinatorics is the theory of counting additive structures in sets. This theory has seen exciting developments and dramatic changes in direction in recent years thanks to its connections with areas such as number theory, ergodic theory and graph theory. This graduate-level 2006 text will allow students and researchers easy entry into this fascinating field. Here, the authors bring together in a self-contained and systematic manner the many different tools and ideas that are used in...

Generalized Additive Models

Published by CRC Press 2006

ISBN 1584884746,9781584884743

410 pages

Now in widespread use, generalized additive models (GAMs) have evolved into a standard statistical methodology of considerable flexibility. While Hastie and Tibshirani's outstanding 1990 research monograph on GAMs is largely responsible for this, there has been a long-standing need for an accessible introductory treatment of the subject that also emphasizes recent penalized regression spline approaches to GAMs and the mixed model extensions of these models. Generalized Additive Models: An...

Additive Number Theory The Classical Bases

Published by Springer Science & Business Media 1996

ISBN 038794656X,9780387946566

342 pages

The classical bases in additive number theory are the polygonal numbers, the squares, cubes, and higher powers, and the primes. This book contains many of the great theorems in this subject: Cauchy's polygonal number theorem, Linnik's theorem on sums of cubes, Hilbert's proof of Waring's problem, the Hardy-Littlewood asymptotic formula for the number of representations of an integer as the sum of positive kth powers, Shnirel'man's theorem that every integer greater than one is the sum of a...

Generalized Additive Models

352 pages

This book describes an array of power tools for data analysis that are based on nonparametric regression and smoothing techniques. These methods relax the linear assumption of many standard models and allow analysts to uncover structure in the data that might otherwise have been missed. While McCullagh and Nelder's Generalized Linear Models shows how to extend the usual linear methodology to cover analysis of a range of data types, Generalized Additive Models enhances this methodology even...

Non-Additive Measure and Integral

Published by Springer Science & Business Media 2013

ISBN 9789401724340,9401724342

178 pages

Non-Additive Measure and Integral is the first systematic approach to the subject. Much of the additive theory (convergence theorems, Lebesgue spaces, representation theorems) is generalized, at least for submodular measures which are characterized by having a subadditive integral. The theory is of interest for applications to economic decision theory (decisions under risk and uncertainty), to statistics (including belief functions, fuzzy measures) to cooperative game theory, artificial...
