This paper proposes a vessel active contour model based on local intensity weighting and vector field. Firstly, the energy function we define is evaluated along evolving curve instead of all image points, value at each point interior exterior weighted means in neighborhood point, which good for dealing with inhomogeneity. Secondly, vascular field derived from vesselness measure employed to guide evolve central skeleton into thin weak vessels. Thirdly, an automatic initialization method that...

Abstract In order to solve the problem of traffic accidents caused by fatigue driving, research EEG signals is particularly important, which can timely and accurately determine state take corresponding measures. Effective improvement measures are an important topic in current scientific field. The purpose this article use analyze driving prevent dangers injuries driving. We designed electroencephalogram (EEG) signal acquisition model collect experimenter, then removed noise through algorithm...

This video demonstrates the preparation of an ultra-thin matrix/analyte layer for analyzing peptides and proteins by Matrix-Assisted Laser Desorption Ionization Mass Spectrometry (MALDI-MS) 1,2. The method involves production a substrate matrix crystals (alpha-cyano-4-hydroxycinnamic acid) on sample plate, which serves as seeding ground subsequent crystallization mixture. Advantages over other deposition approaches (e.g. dried droplet) are that it provides (i) greater tolerance to impurities...

At present, the global positioning system has been widely used in outdoor and navigation, but buildings, thick walls made of cement bricks have a certain blocking effect on satellite signals, resulting severely weakened GPS also extremely it may an impact accuracy, so that task cannot be completed. Inertial sensor is kind mainly detecting measuring acceleration tilt vibration rotation multi-degree-of-freedom motion, important part to solve navigation orientation motion carrier control....

As the Web service technology is using more widely in cloud computing, composition selection has also become one of most popular research fields.

Relying...

At present, the world is facing increasingly severe environmental problems, and green finance one of important means to control pollution.China proposes realize "three one, reduce, compensate" give economy a position transform from high-speed growth high-quality development, so that understanding "green" development concept continuously deepened in all sectors society.The financial sector an pillar modern economic giving full play its functions can effectively promote China's...

Abstract As China opened up over the last thirty years and as huge numbers of foreign-invested enterprises flooded into China, foreign chambers commerce, offering services to their members, have emerged become increasingly influential. Foreign commerce appeared mainly in China’s more economically prosperous regions cities; legal status varies; they can be grouped three types based on general background. They also differ terms internal governance members’ relations with government Party...

In order to accurately describe and analyze human behavior. We need build detailed, accurate user models. The models not only establish what users are interested in, but they also cover the details of users' level interest. Manual modeling or example recommended because apparently these two methods will affect a user's normal programme selections. Research shows that normally reluctant follow instructions, even though aware by doing so desired result be achieved. What want do is find with...
