Modelling and testing consumer trust dimensions in e-commerce [PDF]

open access: yes, 2017
Prior research has found trust to play a significant role in shaping purchase intentions of a consumer. However there has been limited research where consumer trust dimensions have been empirically defined and tested.

The Archimedean trap: Why traditional reinforcement learning will probably not yield AGI [PDF]

open access: yes, 2020
After generalizing the Archimedean property of real numbers in such a way as to make it adaptable to non-numeric structures, we demonstrate that the real numbers cannot be used to accurately measure non-Archimedean structures.

Leibniz's Laws of Continuity and Homogeneity

open access: yes, 2012
We explore Leibniz's understanding of the differential calculus, and argue that his methods were more coherent than is generally recognized. The foundations of the historical infinitesimal calculus of Newton and Leibniz have been a target of numerous ...

An integer construction of infinitesimals: Toward a theory of Eudoxus hyperreals [PDF]

open access: yes, 2012
A construction of the real number system based on almost homomorphisms of the integers Z was proposed by Schanuel, Arthan, and others. We combine such a construction with the ultrapower or limit ultrapower construction, to construct the hyperreals out of

Retroreflecting curves in nonstandard analysis [PDF]

open access: yes, 2009
We present a direct construction of retroreflecting curves by means of Nonstandard Analysis. We construct non self-intersecting curves which are of class C(1), except for a hyper-finite set of values, such that the probability of a particle being ...

A Cauchy-Dirac delta function

open access: yes, 2012
The Dirac delta function has solid roots in 19th century work in Fourier analysis and singular integrals by Cauchy and others, anticipating Dirac's discovery by over a century, and illuminating the nature of Cauchy's infinitesimals and his infinitesimal ...
