The Class 4 4x4 Faithful Representations of S4 over GF(2)
There are 9 conjugacy classes of faithful representations of S4 in the general linear group of 4x4 matrices over GF(2). This report lists the representations belonging to class 4.
Robust and efficient methods for proton computed tomography.
Proton computed tomography (pCT) is a recent promising imaging modality with the goal of generating accurate 3D maps of relative stopping power (RSP) with respect to water. Since the early developments of this imaging ...
Evaluating approaches to detecting ice accretion in and around turbofan jet engines.
The accumulation of ice crystals in the compressor stages of a jet engine causes power loss events during flight that could potentially become catastrophic. The electromagnetic properties of ice clouds make them nearly ...
Primitive Polynomials for the Field GF(3): Degree 2 through Degree 11
This report lists the primitive polynomials over GF(3) of degree 2 through 11. These polynomials were generated using a new matrix-based technique I invented.
Multidimensional power amplifier circuit optimizations for adaptive radar.
As wireless technology and dynamic spectrum allocation continue to proliferate, the ability to dynamically reconfigure radar transmitter power amplifiers will become necessary for adaptive radar. Reconfigurable ...
Generator Pairs for all 4x4 GF(2) Representations of S4
There are nine conjugacy classes of faithful representations of S4 in the general linear group of 4x4 matrices. This report gives generator matrices for one group in each class. These generator pairs allow each of the ...
The design of small propellers operating at low Reynolds numbers and associated experimental evaluation.
Small-scale Unmanned Aerial Systems (UASs) are becoming increasingly important in the field of intelligence, surveillance, and reconnaissance. As the desire for higher payloads and longer flight times increases, so does ...
Faster k-means clustering.
The popular k-means algorithm is used to discover clusters in vector data automatically. We present three accelerated algorithms that compute exactly the same clusters much faster than the standard method. First, we redesign ...
High-density intraoperative brain monitoring during cardiac surgery.
Functional near-infrared spectroscopy (fNIRS) is a prominent technique that allows assessment of functional brain activity by measuring hemodynamic responses. Most existing functional brain imaging methods are only capable ...
Investigation of induced thermo-mechanical response and cure kinetics during processing of carbon fiber reinforced plastics.
The manufacture of laminated composite materials using a thermosetting resin matrix is a complex process that can be understood with a knowledge of cure kinetics, heat transfer, and structural mechanics. During laminate ...
