IEEE Antennas and Propagation Society Newsletter, 1985
This pair of review articles describes various synthesis techniques which have proven useful in determining the excitations of arrays that are to produce desired radiation patterns. Part I deals with equispaced linear arrays and Part II with planar arrays. The latter may have its radiating elements disposed in rectangular, triangular, or circular grids,

Synthesis by rule of english intonation patterns
ICASSP '84. IEEE International Conference on Acoustics, Speech, and Signal Processing, 1984This papet reports work on synthesizing English F0 contours. One motivation for this work is to improve the naturalness and liveliness of the prosody in speech synthesis systems. However, our main goal is to develop a theory of the dimensions of variation controlling intonation, and of their interaction.

Biomimetic synthesis and patterning of silver nanoparticles
Nature Materials, 2002The creation of nanoscale materials for advanced structures has led to a growing interest in the area of biomineralization. Numerous microorganisms are capable of synthesizing inorganic-based structures. For example, diatoms use amorphous silica as a structural material, bacteria synthesize magnetite (Fe3O4) particles and form silver nanoparticles, and

Texture Synthesis of Contrasting Natural Patterns
2012 25th SIBGRAPI Conference on Graphics, Patterns and Images, 2012The seamless integration of the shape and visual attributes of virtual objects is still one of the greatest challenges in Computer Graphics. For some natural objects, such as patterned animals, shape and appearance are mutually connected and therefore the individual treatment of these two aspects difficult the whole process and limits the visual ...

Synthesis of footprint patterns
1988 IEEE AP-S. International Symposium, Antennas and Propagation, 2003Summary form only given, as follows. Planar arrays are potentially useful in space-vehicle applications when the requirement is to provide uniform radiation over a portion of the Earth's surface. Conceptually, proper array excitation will permit control of the ripple in the shaped region of the pattern and control of the sidelobe level in the unshaped ...

Sample-Based Synthesis of Illustrative Patterns
2010 18th Pacific Conference on Computer Graphics and Applications, 2010We present an improved method for synthesis of patterns defined as 2D collection of vector elements. Current solutions to this problem rely on triangulation of the input space or statistical measures of the sample to drive the synthesis step. We propose a method applicable to colored textures, from regular to stochastic, and which provides control over

This chapter discusses the author’s pseudo-normative approach to music making, drawing influences from techno, house, and a range of unconventional vocabularies. There is parallel consideration of moving from drum machine to monosynth, integrating algorithmic control, and then to real-time digital signal processing and generative techniques.

Synthesis of Screentone Patterns of Manga Characters
2019 IEEE International Symposium on Multimedia (ISM), 2019Manga or Japanese comics are a popular medium and their images comprise line drawings and screentones. This study investigates the screentone synthesis task that involves translation from line drawings to manga images. Screentones have regular patterns that are difficult to synthesize.

A procedure for antenna array pattern synthesis
ICASSP '87. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005In this paper, a new iterative method for any shaped pattern synthesis for one- and two-dimensional antenna arrays is described. The object is to meet prescribed constraints on the power pattern, with an assumption on the number of antenna array elements at specified locations.

When radio communication or propagation problems are discussed, an idealized understanding of the expression linear or circular (or, more accurately, elliptical) polarization is usually used. At the same time, in order to simplify any complicated problems, it is forgotten that even a linearly polarized wave propagating near the surface of a lossy ...
