Discontinuous plasmonic‐3D photonic crystal hybrid structures are fabricated in order to evaluate the coupling effect of surface plasmon resonance and stop band. The nanostructures prepared by silver sputtering deposition on top hydrophobic 3D crystals. localized nanostructure has a symbiotic relationship with band, leading highly tunable characteristics. Fluorescence enhancements conjugated polymer quantum dot based these studied. maximum fluorescence enhancement for...

With the development of autonomous driving and communication technology, heterogeneous traffic flow by combining connected vehicles (CAVs) manually driven (MVs) will appear on freeway in near future. It is expected that CAVs can improve capacity reduce vehicle exhaust emissions, but sharing same road MVs cause certain interference to CAVs. In order negative influence flow, setting up CAV dedicated lanes separate from a extent regarded as reasonable solution. Based characteristics should be...

Both the risk of concentration phenomenon for navigation system and encountering unacceptable delay are reduced by guiding risk-averse drivers along reliable paths while avoiding high-risk links as far possible. A constrained dynamic A* algorithm is proposed to search a path subject trip duration constraint in time-dependent road network. The efficiency increased taking advantage information computed off-line. algorithms implemented, their computational performance analyzed simulation.

In this study, we identify the systematic language varieties and discourse characteristics that are indicative of academic writings Chinese American scientists. We conduct a Contrastive Corpus Analysis using computational tool, Gramulator, to features in science journal abstracts as compared abstracts. The results suggest scientists tend employ different linguistic from their counterparts. Specifically, can be characterized non-standard English by choice three items: agent, tense, two major...

Fatigue failure, as the main failure form of aero-engine blades, has a direct impact on reliability and service life aviation equipment. In order to improve performance machined it is necessary understand process mechanism blades then optimize grinding process. This paper takes abrasive belt an 1Cr17Ni2 stainless steel blade research object analyzes fatigue by characterizing surface morphology, cross-sectional microstructure, characteristics blade. The results show that cracks are prone...

This paper describes a new definition of map on the on-board unit (OBU) side as well map-matching method for global navigation satellite system (GNSS)-based Electronic Toll Collection (ETC) system. Key points and links are defined according to highway design an urban area in China order meet needs GNSS-based ETC A algorithm is proposed based this definition. The GPS search changes with running speed vehicle during process. first matches data key nodes instead using links. Next, it exit,...

Constrained A* algorithm is studied to minimize travel time as well delay risk based on reliability analysis when at most limited real traffic information available. The reliable path under the duration constraint searched heuristically by avoiding high-risk links, incident links that are positively dependent far possible through a weight increasing procedure. By making use of computed start trip exploit better lower bound heuristic function, responsive version constrained search proposed...

In this paper, we first describe the concept of cooperative intelligent transport systems (C – ITS) and introduce how advanced ITS technology is being developed in some countries. We then review analyze policies, plans, projects, deployment that support C development Europe. conduct our according to goal white paper on European policy. discuss allocation radio frequency bands as it relates affects pan—European development. addition, standards applied Europe, both communication applications,...

Research of three-dimensional CNC milling machine tool path simulation module based on OpenGL using QT programming tools is introduced in detail. The data explained by the NC interpolation stored linked-list ordered format and then list used for graphics module. steps, data, as well method how to use drawings, realize control drawings facilitating observation, line realizing cutting so are also explained. process can be visualized real time. result translated, zoomed, rotated observed...

There are many 0 km/h speed stop point records in the floating car data (FCD), which has some spatial relations with vehicle queue length front of intersection. A new method for computing intersection based on FCD points was described. First, normal calculated from stops by map matching geographic location stops, continuous relationship between and movement relative to intersections a road link. Second, positional at is basis two-step statistics. Vehicle then stopping distances cars...

A decision circle is proposed for map-matching in the complex region of a road network, and new algorithm introduced to resolve inaccuracy GNSS-based ETC or navigation systems. The can be set particular regions methods adopted. Accurate positioning points on links are collected beforehand instead creating map enable point-to-point map-matching, not point-to-link, such as traditional map-matching. By computing relations between GPS accurate points, relation decided, two steps applied...

Merge points on expressways are areas where a high number of accidents occur, and the connected vehicle technology is an effective means to improve safety these areas. In this study, novel vehicle-coordinated control method proposed reduce occurrence security conflicts congestion by providing early warning driver adjust driving behavior. Vehicle calculated predicted based position speed vehicles that located within range communication technology. First, hazard merge area analyzed. Second,...

Abstract As the subjects to create and construct coherence in discourses, human beings should become focus of study. This paper points out linguistic philosophical nature discourse discusses existence, dynamicity, plasticity dialogicity among based on Bakhtin’s Theory Dialogue. We demonstrate construction basis intentional space, which consists theme, subject, whole context (or TSW structure). analyzes two poems, one a Chinese poem other an English poem, as examples verify space process....
