Network modeling in electromagnetics is an effective technique in treating scattering problems by canonical and complex structures. Geometries constituted of angular regions (wedges) together with planar layers can now be approached with the Generalized Wiener-Hopf Technique supported by network representation in spectral domain. Even if the network representations in spectral planes are of gre...

. We measure and compare the effects of changing the programming language in introductory level courses (Computer Science I and II) in undergraduate Computer Science (CS) curriculum. The study presents the example of University of Texas at Dallas (UTD) case, where we present the results of two approaches: Approach 1 where both CS I and CS II courses are taught in Java, and Aprroach 2 where CS I...

Existing vision-based action recognition is susceptible to occlusion and appearance variations, while wearable sensors can alleviate these challenges by capturing human motion with one-dimensional time-series signal. For the same action, knowledge learned from vision sensors, may be related complementary. However, there exists significantly large modality difference between data captured wearab...

3D human action recognition is crucial in broad industrial application scenarios such as robotics, video surveillance, autonomous driving, or intellectual education, etc. In this paper, we present a new point cloud sequence network called PointMapNet for recognition. PointMapNet, two feature maps symmetrical to depth are proposed summarize appearance and motion representations from sequences. S...

Human activity recognition has become a significant research trend in the fields of computer vision, image processing, and human–machine or human–object interaction due to cost-effectiveness, time management, rehabilitation, pandemic diseases. Over past years, several methods published for human action using RGB (red, green, blue), depth, skeleton datasets. Most introduced classification datase...

The electromagnetic scattering from a large planar strip composed of parallel free-standing dense metallic strips is addressed. The scattered field is evaluated by resorting to a couple of different methods: an asymptotic technique, namely the Uniform Geometrical Theory of Diffraction (UTD), and a numerical method (the Method of Moments, MoM). The results of a numerical investigation are presen...

BACKGROUND Pediatric immunization rates have increased in the United States since 1990. Nevertheless, national survey data indicate that up to one third of 2-year-old children in some states and urban areas lack at least one recommended dose of diphtheria-tetanus-pertussis (DTP)-, polio-, or measles-containing vaccines. Immunization has become a key measure of preventive pediatric health care i...
