In March 2016, Barnes & Noble Education enlarged their Digital Student Solutions online services division by acquiring LoudCloud Systems, a digital platform and analytics provider to clients in higher education, the for-profit sector, and K-12 segment. [19] In August 2017, Barnes & Noble Education acquired Student Brands for $58.5 million. [20]
In August 2010, concurrently with introducing a web-based textbook rental service, Barnes and Noble—"one of the largest textbook retailers in the US" [59] —introduced the NOOK Study app "for the PC or Mac that lets users buy or rent e-book versions of their textbooks for use on the computer. [60]
The Bachelor of Science in Nursing (BSN, BScN) also known in some countries as a Bachelor of Nursing (BN) or Bachelor of Science (BS) with a Major in Nursing is an academic degree in the science and principles of nursing, granted by an accredited tertiary education provider.
Although the three-peg version has a simple recursive solution long been known, the optimal solution for the Tower of Hanoi problem with four pegs (called Reve's puzzle) was not verified until 2014, by Bousch. [20] However, in case of four or more pegs, the Frame–Stewart algorithm is known without proof of optimality since 1941. [21]
Plot of the Bring radical for real argument. In algebra, the Bring radical or ultraradical of a real number a is the unique real root of the polynomial + +.. The Bring radical of a complex number a is either any of the five roots of the above polynomial (it is thus multi-valued), or a specific root, which is usually chosen such that the Bring radical is real-valued for real a and is an ...
The second book of the Mode series by Piers Anthony, Fractal Mode, describes a world that is a perfect 3D model of the set. [ 48 ] The Arthur C. Clarke novel The Ghost from the Grand Banks features an artificial lake made to replicate the shape of the Mandelbrot set.
In statistics, ordinary least squares (OLS) is a type of linear least squares method for choosing the unknown parameters in a linear regression model (with fixed level-one [clarification needed] effects of a linear function of a set of explanatory variables) by the principle of least squares: minimizing the sum of the squares of the differences between the observed dependent variable (values ...
A so-called eigenmode is a solution that oscillates in time with a well-defined constant angular frequency ω, so that the temporal part of the wave function takes the form e −iωt = cos(ωt) − i sin(ωt), and the amplitude is a function f(x) of the spatial variable x, giving a separation of variables for the wave function: (,) = ().
