A new efficient technique for the analysis of complex antenna around a scatterer is proposed in this paper, termed the iterative vector fields with uniform geometrical theory of diffraction (UTD) technique. The complex field vector components on the closed surface enclosing the antenna without platform are computed by higher order Method of Moments (MOM), and the scattered fields from the platf...

Proposing a novel hybrid uniform theory of diffraction-physical optics (UTD-PO) formulation, we develop method to calculate the E-plane radiation pattern corrugated rectangular horn antennas with corrugations. We derive technique from estimation total field that reaches emitting source (a magnetic current line), thereby assuming impingement plane wave above (reciprocity is applied). To validate...

In this paper we provide a modified 3D Uniform Theory of Diffraction (UTD) model for finite-length cylinder, and validate the by comparing to simulation measured data. The presented finite-cylinder UTD is adapted from conventional infinite-cylinder model, additionally add edge diffraction occurring at cap finite cylinder. reference obtained CST measurement vector network analyzer based channel ...

SpaceEval (SemEval 2015 Task 8), which concerns spatial information extraction, builds on the spatial role identification tasks introduced in SemEval 2012 and used in SemEval 2013. Among the host of subtasks presented in SpaceEval, we participated in subtask 3a, which focuses solely on spatial relation extraction. To address the complexity of a MOVELINK, we decompose it into smaller relations s...

This paper describes the open-source Phrase-Based Statistical Machine Translation Decoder Phramer. The paper also presents the UTD (HLTRI) system build for the WMT06 shared task. Our goal was to improve the translation quality by enhancing the translation table and by preprocessing the source language text

BACKGROUND Increasing numbers of families in the United States are adopting children who were born in other countries. Appropriate immunization of internationally adopted children provides a challenge to pediatricians who must evaluate documentation of vaccines administered overseas and fulfill the recommended US childhood immunization schedule. The acceptability of vaccinations received outsid...

Pine wilt disease (PWD), which is caused by the Bursaphelenchus xylophilus, one of most serious biological invasions in East Asia. Removal infected pine trees generally used to prevent spread PWD. However, how this strategy affects plant species diversity and ecosystem functions needs be clarified. We compared alpha diversity, composition, biomass for all woody species, adults, saplings, seedli...

In this paper, we present the design and evaluation of a system that automatically constructs accurate radio maps for both devicebased and device-free WLAN localization systems. The system uses 3D ray tracing enhanced with the uniform theory of diffraction (UTD) to model the electric field behavior and the human shadowing effect.
