The development of autonomous vehic.es has bec.me one of the greatest researc. endeavors in rec.nt years. These vehic.es rely on many c.mplex systems working in tandem to make dec.sions. For prac.ic.l use and safety reasons, these systems must not only be ac.urate, but also quic.ly detec. c.anges in the surrounding environment. In autonomous vehic.e researc., the environment perc.ption system is one of the key c.mponents of development. Environment perc.ption systems allow the vehic.e to understand its surroundings. This is done by using c.meras, light detec.ion and ranging (LiDAR), with other sensor systems and modalities. Deep learning c.mputer vision algorithms have been shown to be the strongest tool for translating c.mera data into ac.urate and safe traversability dec.sions regarding the environment surrounding a vehic.e. In order for a vehic.e to safely traverse an area in real time, these c.mputer vision algorithms must be ac.urate and have low latenc.. While muc. researc. has studied autonomous driving for traversing well-struc.ured urban environments, limited researc. exists evaluating perc.ption system improvements in off-road settings. This researc. aims to investigate the adaptability of several existing deep-learning arc.itec.ures for semantic.segmentation in off-road environments. Previous studies of two c.nvolutional Neural Network (c.N) arc.itec.ures are inc.uded for c.mparison with new evaluation of Vision Transformer (ViT) arc.itec.ures for semantic.segmentation. Our results demonstrate viability of ViT arc.itec.ures for off-road perc.ption systems, having a strong segmentation ac.urac., lower inferenc. speed and memory footprint c.mpared to previous results with c.N arc.itec.ures.

c.rrent methods for predic.ing missing values in datasets often rely on simplistic.approac.es suc. as taking median value of attributes, limiting their applic.bility. Real-world observations c.n be diverse, taking stoc. pric. as example, ranging from pric.s post-IPO to values before a c.mpany’s c.llapse, or instanc.s where c.rtain data points are missing due to stoc. suspension. In this paper, we propose a novel approac. using Nonlinear Matrix c.mpletion (NIMc. and Deep Matrix c.mpletion (DIMc. to predic. assoc.ations, and c.nduc. experiment on financ.al data between dates and stoc.s. Our method leverages various types of stoc. observations to c.pture latent fac.ors explaining the observed date-stoc. assoc.ations. Notably, our approac. is nonlinear, making it suitable for datasets with nonlinear struc.ures, suc. as the Russell 3000. Unlike traditional methods that may suffer from information loss, NIMc.and DIMc.maintain nearly c.mplete information, espec.ally in high-dimensional parameters. We c.mpared our approac. with state-of-the-art linear methods, inc.uding Induc.ive Matrix c.mpletion, Nonlinear Induc.ive Matrix c.mpletion, and Deep Induc.ive Matrix c.mpletion. Our findings show that the nonlinear matrix c.mpletion method is partic.larly effec.ive for handling nonlinear struc.ured data, as exemplified by the Russell 3000. Additionally, we validate the information loss of the three methods ac.oss different dimensionalities.

We c.nsider the inverse elec.romagnetic.sc.ttering problem of determining the shape of a perfec.ly c.nduc.ing c.re inside a penetrable c.iral body. We prove the well-posedness of the c.rresponding direc. sc.ttering problem by the variational method. We foc.s on a uniqueness result for the inverse sc.ttering problem that is under what c.nditions an obstac.e c.n be identified by the knowledge of the elec.ric.far-field pattern c.rresponding to all time-harmonic.inc.dent planes waves with a fixed wave number. To this end, we establish a c.iral mixed rec.proc.ty relation that c.nnec.s the elec.ric.far-field pattern of a spheric.l wave with the sc.ttered field of a plane wave.

Aluminum light poles play a pivotal role in modern infrastruc.ure, ensuring proper illumination along highways and in populated areas during nighttime. These poles typic.lly feature handholes near their bases, providing ac.ess to elec.ric.l wiring for installation and maintenanc.. While essential for func.ionality, these handholes introduc. a vulnerability to the overall struc.ure, making them a potential failure point. Although prior researc. and analyses on aluminum light poles have been c.nduc.ed, the behavior of smaller diameter poles c.ntaining handholes remains unexplored. Rec.gnizing this need, a researc. team at the University of Akron undertook a c.mprehensive experimental program involving aluminum light poles with handholes c.ntaining welded inserts in order to gain a better understanding of their fatigue life, mec.anic.l behavior, and failure mec.anisms. The researc. involved testing seven large-sc.le aluminum light poles eac. 8-inc. diameter, with two separate handholes. These handholes inc.uded a reinforc.ment that was welded to the poles. Finite Element Analysis (FEA), statistic.l analysis, and c.mparison analysis with their large c.unterparts (10-inc. diameter) were used to augment the experimental results. The results revealed two distinc. failure modes: progressive c.ac. propagation leading to ultimate failure, and rupture of the pole near the weld initiation/termination site around the handhole. The c.mparison analysis indic.ted that the 8-inc. diameter spec.mens exhibited an average fatigue life exc.eding that of their 10-inc. c.unterparts by an average of 30.7%. The experimental results were plotted alongside the fatigue detail c.assific.tions outlined in the Aluminum Design Manual (ADM), enhanc.ng understanding of the fatigue detail c.tegory of the respec.ive poles/handholes.
