This paper proposes an improved droop control strategy based on changeable reference in low-voltage microgrids. To restore running frequency of distributed generation to a rated value without affecting its reactive power output, changeable frequency reference, mainly compensating for frequency deviation, are proposed corresponding to various load demands. In terms of active power sharing inaccu...

The development of veracious models of the Internet topology has received a lot of attention in the last few years. Many proposed models are based on topologies derived from RouteViews [1] BGP table dumps (BTDs). However, BTDs do not capture all AS–links of the Internet topology and most importantly the number of the hidden AS–links is unknown, resulting in AS–graphs of questionable quality. As...

Ag nanowire-grid polarizers (NWGPs) were prepared by a one-step fabrication method, called liquid-bridge-mediated nanotransfer molding (LB-nTM). LB-nTM is a new direct nano-patterning method based on the direct transfer of various materials from a mold to a substrate via liquid layer. We fabricated NWGPs with Ag nanowire arrays (81 nm parallel lines and 119 nm spaces) on 2.5 in. transparent sub...

XGobi is a data visualization system with state-of-the-art interactive and dynamic methods for the manipulation of views of data. It implements 2-D displays of projections of points and lines in high-dimensional spaces, as well as parallel coordinate displays and textual views thereof. Projection tools include dotplots of single variables, plots of pairs of variables, 3-D data rotations, variou...

Programmers working on large software systems are faced with an extremely complex, information-rich environment. To help navigate through this, modern development environments allow flexible, multi-window browsing and exploration of the source code. Our focus in this paper is on pretty-printing algorithms that can display source code in useful, appealing ways in a variety of styles. Our algorit...

We consider an interactive browsing environment for 3D scenes, which allows for the dynamic optimization of selected client views by distributing available transmission resources between geometry and texture components. Texture information is available at a server in the form of scalably compressed images, corresponding to a multitude of original image views. Surface geometry is also available ...

This position paper describes the SHriMP visualization tool and how we are customizing it for browsing Java programs. Available visualizations include views of the Java source code, generated Java documentation, personalized annotations and several architectural views. The architectural views, displayed graphically as nested graphs, provide an interface through which the textual lower-level vie...

Trees are a valuable way of displaying structure in datasets, especially for classification problems. Improved classification results can be achieved using forests of trees. Adding various visualization methods and interactive tools for analysis of individual trees and of whole forests gives complementary insight into the data. This paper describes different views and methods to analyze tree fo...

Since infectious diseases heed no national borders, international research collaboration across borders must be enhanced. The Ministry of Education, Culture, Sports, Science and Technology (MEXT) of Japan launched the J-GRID program in the fiscal year (FY) 2005, which consists of the two elements; (1) the construction of collaboration centers in Asian and African countries on a reciprocal basis...
