Any AM antenna system consists of the antenna itself, some sort of transmission line to convey the RF energy from the transmitter to the antenna, and some sort of impedance matching network. Directional antenna systems consist of multiple radiating elements, transmission lines and matching networks. In this paper, we will examine in building-block fashion the components that make up such system...

This paper proposes automatic representations of spatial relationships among photos for structure analysis and review of a photographic subject. Based on camera tracking, photos are shown in a 3D virtual reality space to represent global spatial relationships. At the same time, the spatial relationships between two of the photos are represented in slide show sequences. This proposal allows peop...

The polycrystalline double perovskite Li2GdFeTiO6 was synthesized through the solid-state mixed oxide method and its preliminary crystal structure investigated by XRD technique. of material identified to be tetragonal with space group P4bm using POWD MATCH software. morphology sample a scanning electron microscope (SEM) average grain size found 3.82 μm intercept investigation phase various vibr...

Seeking reliable correspondences between two feature sets is a fundamental and important task in computer vision. This paper attempts to remove mismatches from given putative image feature correspondences. To achieve the goal, an efficient approach, termed as locality preserving matching (LPM), is designed, the principle of which is to maintain the local neighborhood structures of those potenti...

Presenting a set of similar or diverse ideas during the idea generation process leads ideators to come-up with more creative and diverse ideas. However, to better assess the similarity between the ideas, we designed two matching systems, namely I-Match and OntoIdea. In the context of the idea generation process, each idea is represented by a set of instances from DBpedia describing the main con...

Merging virtual object with human video sequence is an important technique for many applications such as special effects in movies and augmented reality. In a traditional method, the operator manually fit 3D body model onto the human video sequence, and generate virtual objects at the current 3D body pose. However, the manual fitting is a time consuming task, and the automatic registration is r...
