Dr. Cory Prust’s door is always open to his students – and each spring the associate professor of electrical engineering has more than a few treat him with an unexpected visit.
“I will have these moments when they run into my office – just smiling ear to ear–saying ‘It works, its works!’” Prust said.

Method for Low Sidelobe Operation of a Phased Array Antenna Having Failed Antenna Elements
US8354960B2
2013
Described is a method of modifying an antenna pattern for a phased array antenna having at least one failed antenna element. A number of proximate beamformers in a proximate angular region about a beamformer at an angle of interest are determined. Each of the proximate beamformers has a proximate beamformer weight vector. A corrected beamformer weight vector is determined for the angle of interest as a linear combination of the proximate beamformer weight vectors. Each element of the corrected beamformer weight vector that corresponds to one of the failed antenna elements has a value of zero. The method enables computation of low spatial sidelobe antenna patterns without requiring a recalibration of the antenna thereby enabling uninterrupted operation of systems that employ phased array antennas. The method can also be used to control taper loss or sidelobe level for phased array antennas that have no failed antenna elements.

Senior Design: The Swiss Army Knife of the Curriculum
American Society of Engineering Education North Midwest Section ConferencePrust, C.J., Williams, S.M.
2013
Over the years, senior design courses in engineering curricula have been subject to numerous internal and external driving forces. Widespread adoption of senior design capstone experiences was dictated by the then Accreditation Board for Engineering and Technology (ABET) in the mid-1980’s. At that time, ABET began to specify a “culminating design experience” for all accredited engineering curricula.
Low sidelobe antenna patterns with failed elements
IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)Krich, S.I., Weiner, I., Prust, C.J.
2012
Many radar and communication systems utilize phased antenna arrays where it is desirable to maintain low-sidelobes even when one or more individual antenna elements have failed. Traditionally, computing low-sidelobe beamforming with disabled elements requires accurate antenna element patterns. In this paper we present a new algorithm for computing low-sidelobe beamforming that only requires the original beamforming weights that produce low sidelobes when all elements are functioning normally. The algorithm is computationally inexpensive, does not require accurate knowledge of the antenna element patterns, and permits user adjustment of the trade-off between sidelobe level, taper loss, and mainbeam width. Near optimum low sidelobes are demonstrated in several examples.
Highly scalable methods for exploiting a label with unknown location in order to orient a set of single-particle cryo electron microscopy images
SPIE/IS&T Electronic Imaging ConferencePrust, C.J., Wang, Q., Doerschuk, P.C., Johnson, J.E.
2012
A highly scalable method for determining the projection orientation of each image in a set of cryo electron microscopy images of a labeled particle is proposed. The method relies on the presence of a label that is a sufficiently strong scatterer such that its 2-D location in each image can be restricted to at most a small number of sites by processing applied to each image individually. It is not necessary to know the 3-D location of the label on the particle. After first determining the possible locations of the label in the 2-D images in parallel, the information from all images is fused to determine the 3-D location of the label on the particle and then the 3-D location is used to determine the projection orientation for each image by processing each image individually. With projection orientations, many algorithms exist for computing the 3-D reconstruction. The performance of the algorithm is studied as a function of the label SNR.
Model-based statistical inference problems concerning non-linear 3-D tomography with applications to the structural biology of asymmetric virus particles
Purdue UniversityPrust, C.J.
2006
Electron microscopy provides noisy images of viruses that, quantitatively, are projections of the 3-D virus structure. The ensuing tomographic reconstruction problem is nonlinear since the orientation of each particle is unknown and only one image can be measured for each particle and hence, the measured image is related to an unknown 2-D projection of the structure. Statistical models can be formulated for both measurement noise and orientation uncertainty. Inference problems on parameters describing the 3-D virus structure can then be investigated by fusing data from single images of many identical particles. High-order symmetry of the particle, especially icosahedral symmetry, has been helpful in previous computations of such structures. In this work we consider reconstruction methods that are not based on total-particle symmetry. First we consider reconstruction of a spatially localized deviation from symmetry. We describe mathematical models and a two-stage algorithm for 3-D reconstruction of a tailed bacteriophage where the symmetries of the capsid and tail are incompatible. Numerical results from experimental images are presented for bacteriophage P22. In the second phase of this work we present statistical algorithms in which an initial symmetrical reconstruction undergoes relaxation of the symmetry constraint. Both algorithms and Cramer-Rao Bounds on performance of algorithms are presented. We believe such algorithms would be most useful in computing reconstructions of viruses having a symmetrical capsid and an asymmetrical nucleic acid core. A primary focus of this work is development of statistical tools for experimental design.
An Introductory Communication Systems Course with MATLAB/Simulink Based Software-Defined Radio Laboratory

In recent years, software-defined radio (SDR) has become increasingly popular in electrical and computer engineering education as a tool for teaching communication systems, networking, and digital signal processing. Adoption of SDR has been enabled through decreasing hardware costs, mature and widely available software development tools, and educational resources aimed at effectively utilizing SDR in undergraduate education. A survey of the current engineering education literature shows that SDR technology has been widely adopted in advanced digital communications and networking courses, elective courses focusing on SDR technology itself, as an enabling technology in senior capstone or research projects, and as a demonstration and motivational tool supplementing existing courses or laboratories.This paper presents an introductory physical-layer analog and digital communication systems course which has been designed to use modern SDR hardware and supporting software tools as an integral part of the course.
