Generalizing the Lorentz transformations
James M. Chappell, David L. Berkahn, Nicolangelo Iannella +3
In this paper we develop a framework allowing a natural extension of the Lorentz transformations. To begin, we show that by expanding conventional four-dimensional spacetime to eig…
A brief study of time
James M. Chappell, John G. Hartnett, Azhar Iqbal +2
Understanding the nature of time remains a key unsolved problem in science. Newton in the Principia asserted an absolute universal time that {\it `flows equably'}. Hamilton then pr…
A new derivation of the Minkowski metric
James M. Chappell, John G. Hartnett, Nicolangelo Iannella +3
The four dimensional spacetime continuum, as first conceived by Minkowski, has become the dominant framework within which to describe physical laws. In this paper, we show how this…
A Neuromorphic VLSI Design for Spike Timing and Rate Based Synaptic Plasticity
Mostafa Rahimi Azghadi, Said Al-Sarawi, Derek Abbott +1
Triplet-based Spike Timing Dependent Plasticity (TSTDP) is a powerful synaptic plasticity rule that acts beyond conventional pair-based STDP (PSTDP). Here, the TSTDP is capable of…
An explanation for galaxy rotation curves using a Clifford multivector spacetime framework
James M. Chappell, Nicolangelo Iannella, Azhar Iqbal +1
We explore the consequences of space and time described within the Clifford multivector of three dimensions , where space consists of three-vectors and time is described…
Design and Implementation of BCM Rule Based on Spike-Timing Dependent Plasticity
Mostafa Rahimi Azghadi, Said Al-Sarawi, Nicolangelo Iannella +1
The Bienenstock-Cooper-Munro (BCM) and Spike Timing-Dependent Plasticity (STDP) rules are two experimentally verified form of synaptic plasticity where the alteration of synaptic w…
