Recently, ultra-wideband (UWB) impulse radio systems based on noncoherent detection, such as transmitted reference and differential modulation systems, have drawn a lot of attention for their potential applications in low-rate and low-cost communications. In this paper, a unified approach is presented to develop and analyze a noncoherent multiple-symbol(More)
Due to the emergence of grid computing, which has linked up all the various resources widely distributed (eg: computing resources, storage resources, software resources, information resources, etc.) through the Internet, grid scheduling has become a new focus on grid research. However, a suitable and efficient scheduling algorithm is also badly needed(More)
Due to the rapid evolution of grid computing, which deals with the effective utilization of the globally distributed computer resources to solve massive problems, grid scheduling is the major focus. Efficient scheduling algorithms are the need of the hour to achieve efficient utilization of the unused CPU cycles distributed geographically in various(More)
In the 21st century, product design becomes more rapid, modular and knowledge-based. Oriented to these characteristics, design guide management system is established based on Workflow Management System in this paper, and it provides enterprises with an effective method for knowledge accumulation and reuse in design processes. With analysis on features in(More)
Cooperative self-assembly behavior of rod-coil-rod poly(γ-benzyl-l-glutamate)-block-poly(ethylene glycol)-block-poly(γ-benzyl-l-glutamate) (PBLG-b-PEG-b-PBLG) amphiphilic triblock copolymers and hydrophobic gold nanoparticles (AuNPs) was investigated by both experiments and dissipative particle dynamics (DPD) simulations. It was discovered that pure(More)
With the diversification of customer needs and the widely use of 3D CAD systems, in order to make the 3D CAD system truly become the best carrier of professional technologies and realize the accumulation and reuse of enterprise design knowledge and design process, a design knowledge management method based on 3D CAD system is presented. In this method, a(More)
To solve the problem of low growth rate and metabolism level in suspension cultures of protocorm-like bodies (PLBs) of Dendrobium huoshanense. The effects of germanium on PLB proliferation and accumulation of polysaccharides together with nutrient utilization were investigated and the contents of reducing sugars, soluble proteins, the activities of(More)
The self-organization of pre-assembled aggregates is an efficient stepwise strategy for fabricating nanostructures with a second level of hierarchy. Herein, we report that anisotropic spindle-like micelles, self-assembled from polypeptide graft copolymers with rigid backbones, can serve as ideal pre-assembled subunits for constructing one-dimensional(More)
Constructing polymeric toroids with a uniform, tunable size is challenging. Reported herein is the formation of uniform toroids from poly(γ-benzyl-l-glutamate)-graft-poly(ethylene glycol) (PBLG-g-PEG) graft copolymers by a two-step self-assembly process. In the first step, uniform rodlike micelles are prepared by dialyzing the polymer dissolved in(More)
