In this paper, we present an intuitive and controllable patch-based technique for terrain synthesis. Our method is based on classical patch-based texture synthesis approaches. It generates a new terrain model by combining patches extracted from a given set of exemplars, providing a control performed by a low frequency guide, a categorization of exemplars, and a map for distributing these catego...

Controllable synthesis and surface engineering of nanomaterials are of strategic importance for tailoring their properties. Here, we demonstrate that the synthesis and surface adjustment of highly stable hierarchical of SnO2 nanospheres can be realized by biomineralization, vulcanization and oxidation techniques. Furthermore, we reveal that the highly stable hierarchical SnO2 nanospheres ensure...

In this paper, the supervisory control synthesis of modular or distributed discreteevent systems is discussed. The coordination-control architecture proposed by Komenda and van Schuppen (2008) and studied for prefix-closed specification languages by Komenda et al. (2010a,b) is generalized to the case of non-prefix-closed global specification languages and non-prefix-closed plant languages. Nece...

Developing a high-performance photocatalyst and a photoelectrode with enhanced visible light harvesting properties is essential for practical visible light photocatalytic applications. Noble metal-free, highly visible light-active, elemental red phosphorus (RP) was prepared by a facile mechanical ball milling method, which is a reproducible, low cost and controllable synthesis process. The synt...

Gold octahedra with hollow features have been synthesized in high yield via the controlled overgrowth of preformed concave cube seeds. This Ag(+)-assisted, seed-mediated synthesis allows for the average edge length of the octahedra and the size of the hollow features to be independently controlled. We propose that a high concentration of Ag(+) stabilizes the {111} facets of the octahedra throug...

This paper discusses a new approach to acoustic amplitude modulation. Building on prior work with electromagnetic augmentation of acoustic instruments, we begin with a theory of operation model to describe the mechanical forces necessary to produce acoustic amplitude modulation synthesis. We then propose an implementation of our model as an instrumental prototype. The results illustrate that ou...

In this paper, controllable synthesis of various ZnO nanostructures was achieved via a simple and cost-effective hydrothermal process on the Si substrate. The morphology evolution of the ZnO nanostructures was well monitored by tuning hydrothermal growth parameters, such as the seed layer, solution concentration, reaction temperature, and surfactant. X-ray diffraction and photoluminescence meas...

A novel method is developed to enable the formation, positioning, and patterning of individual metal nanoclusters with controllable and monodispersed sizes down to 1-2 nm scale. The method is generic for fabricating designed arrays of virtually any type of metal nanoparticles well below 10 nm. Among the wide range of potential applications in surface and materials science, the nanoparticle arra...
