Objectives The aims of this study were (1) to identify the timing of the mid-growth spurt (MGS) in stature in children and (2) to identify gross motor coordination (GMC) spurts when aligned by the age of attainment of the MGS (aMGS). Methods Stature, weight, and GMC were measured in 245 Portuguese children followed annually from 6 to 10 years. GMC was assessed and to estimate children's MGS in stature as well as GMC spurts in each of the four tests aligned by aMGS, we used a nonsmoothed polynomial methodology. Results In boys, the aMGS was attained at 7.8 years, whereas in girls it was 8.0 years. In boys, the peak MGS was 6.2 cm center dot yr(-1) and in girls it was 6.4 cm center dot yr(-1). In boys, the peak for walking backwards (WB) occurred 18 months before aMGS (14.9-points center dot yr(-1)), jumping sideways (JS) was 12 months after aMGS (13.5-points center dot yr(-1)), hopping on one leg (HO) was 18 months before aMGS (11.7-points center dot yr(-1)), and shifting platform (SP) was 12 months before aMGS (6.8-points center dot yr(-1)). In girls, WB spurts occurred 12 months after aMGS (13.3-points center dot yr(-1)), JS was 12 months before aMGS (10.5-points center dot yr(-1)), HO was coincident with aMGS (10.4-points center dot yr(-1)), and SP was 18 as well as 12 months before aMGS (7.2-points center dot yr(-1)). No differences were observed in the mean peak spurts between sexes in the GMC tests. Conclusions Boys and girls reached their MGS in stature at about the same chronological age. Spurts in GMC did not express themselves in the same biological timing relative to aMGS in stature, and there are sex differences.

Nowadays,the manufacturing execution management system(MES) has been widely used in industrial production,and the query operation in the user interface of the MES system is one of the commonly used *** common implementation method is to directly write the corresponding code according to the specific query requirements,but with the increasing query requirements,message frequent changes,there are practical problems such as large amount of code,repeated work,poor generality,and high system maintenance *** view of this situation,the common operating elements of query processing logic and human-computer interaction are extracted,and a general query module is designed and implemented by drawing on the existing general query system design ideas.

Over the last few years, the complexity of web applications has increased to provide more dynamic web applications to users. The drawback of this complexity is the growing number of errors in the front-end applications. In this paper, we present BikiniProxy, a novel technique to provide self-healing for the web. BikiniProxy is designed as an HTTP proxy that uses five self-healing strategies to rewrite the buggy HTML and javascript code. We evaluate BikiniProxy with a new benchmark of 555 reproducible javascript errors of which 31.76% can be automatically self-healed.

In a large virtual environment, people always tend to lost themselves because of they are unfamiliar to the VE. Autonomous roaming combined with the eagle eye navigator could assist the positioning in the larger scene. This article sets up a bridge between three-dimensional virtual scene and the twodimensional plane using the web scripting language- java script. Thus they are synchronized to the HTML page. It allows the visitor to understand the current position of the large virtual scene and anyone can roam unimpeded in the scene.

This paper presents a successive approach register (SAR) analog-to-digital converter (ADC) with a novel hybrid digital-to-analog converter (DAC) architecture: half junction splitting (J.S.) and half binary weighted capacitor DAC. This DAC maintains low power consumption of J.S. DAC and the high signal-to-noise plus distortion ratio (SNDR) of binary weighted capacitor DAC. The power dissipation of the circuit is 1.72μW, SNDR 59.17dB, spurious free dynamic range (SFDR) 7339dB, and the FOM 23.2fj/conversion step with 0.9V supply voltage. The proposed circuit is fabricated in TSMC 0.18μm 1P6M CMOS process technology.
全球信息化的浪潮接踵而至,社会各个行业正朝着信息化前进,我国已将信息相关产业作为国家大力支持的可持续发展战略。伴随GIS的迅速发展,它与各个行业之间相互渗透、相互促进的作用也将越趋明显。GIS的发展实质是促进地理信息产业的建设和发展。GIS与铁路管理相结合,能够优化促进铁路沿线设备及人员的管理与调度,铁路地理信息系统(RGIS)的发展很大程度上将会影响我国铁路的发展。因此铁路地理信息系统(RGIS)作为国家信息产业的重要组成部分,必将获得巨大发展。本文基于Arc GIS API for java script等相关技术设计并实现了一个铁路GIS接口平台。该系统能够访问Arc GIS Server发布的铁路地图,并以应用编程接口API的形式向上层应用系统提供对铁路地图和公里标的各种操作。论文研究并分析了GIS在各个应用领域的应用与实践,总结了铁路地理信息系统(RGIS)的相关技术;分析了铁路GIS系统的功能需求和性能需求;设计了铁路GIS接口平台的总体框架;实现了铁路GIS接口平台中的公里标操作和地图操作功能模块;最后将设计和实现的铁路GIS接口平台应用到铁路局几个应用系统中,验证了该平台的兼容性和直观丰富的界面效果,达到了铁路局的预期。本文的主要研究内容和取得的成果如下:1)分析了Arc GIS软件家族各个工具的功能特点,以及国内外各种地理信息软件的应用现状。2)完成了铁路地图上与公里标操作相关接口函数的设计与实现,包括公里标测距、坐标转换、公里标打点以及得到最大最小公里标等;3)实现了与地图操作有关的各个接口函数,包括地图事件、地图基本服务、地图图层、地图层级等各种对铁路地图的基本操作;4)设计并实现了铁路GIS接口平台的后台服务程序,不仅提高了GIS接口访问数据库效率,而且简化了GIS接口的代码;5)利用Arc GIS软件产品完成了地图的制作、地图服务发布以及地图缓存的创建,在加快访问地图服务的同时,也提高了整个系统的性能。
