The industrial connections in Donald Judd's art

This paper examines the context and impact of the industrial materials and processes of the mid-twentieth century on Donald Judd's works, focusing on galvanized steel, cellulose nitrate paints, anodizing, and the RAL color matching system. Exploration of the industrial materials and methods Judd utilized provides a greater understanding of his processes, choices, and ultimately his art, its care, and legacy.     

智慧城市信息安全风险评估模型构建与实证研究

[目的/意义] 面对智慧城市日益突出的信息安全问题,提出一个科学的风险评估模型,以快速对智慧城市进行风险分类并分析风险因素。[方法/过程] 从智慧城市信息安全的5个层次和风险评估的4个主要因素出发,构建智慧城市信息安全风险指标框架,对智慧城市实例进行ward系统聚类形成分类属性,选择C4.5算法的决策树方法建立风险评估模型,并验证模型的科学性。[结果/结论] 结果发现:安全管理制度、数据泄露与损坏威胁、安全意识薄弱性和设备安全漏洞是智慧城市之间差距最显著的风险因素,根据评估结果提出保障智慧城市信息安全的建议。     

潮州产10种野菜中硝酸盐、亚硝酸盐及Vc的含量

利用分光光度法测定了潮州产10种野菜中硝酸盐、亚硝酸盐的含量，利用氧化还原滴定法测定了维生素ca含量．结果表明：月光花、决明、铁苋菜和叶下珠的硝酸盐含量低于轻度污染水平（432mg／kg鲜重），亚硝酸盐含量低于无公害蔬菜亚硝酸盐含量的限量标准（44．0mg／kg鲜重），它们属于一级野菜，可以安全食用；鸡矢藤、白勒和苎麻的硝酸盐含量低于785mg／kg，属于中度污染水平，亚硝酸盐含量低于无公害蔬菜亚硝酸盐含量的限量标准，属二级蔬菜范围，不宜生食，煮熟或盐渍可安全食用；鳢肠硝酸盐含量高于785mg／蚝而低于1440mg／kg，亚硝酸盐含量低于无公害蔬菜亚硝酸盐含量的限量标准，维生素C含量高于50mg／100g鲜重，属于三级蔬菜，不可生食和盐渍，可熟食。牡荆和肖梵天花虽然硝酸盐含量很低，但维生素C含量较低，亚硝酸盐含量高于无公害蔬菜亚硝酸盐含量的限量标准，所以不宜食用．     

谈义乌市公示语的英译

良好的国际化语言环境是国际化城市建设的保证。义鸟市公示语英译还存在着浮于表面的解读、选词欠地道、简单的字字对应、不规范的书写等不足。针对这些问题，建议采取建立行政管理机构、推行翻译人员持证上岗制度、加强公众舆论监督等具体措施。     

Assessment of three-dimensional joint kinematics of the upper limb during simulated swimming using wearable inertial-magnetic measurement units

The analysis of the joint kinematics during swimming plays a fundamental role both in sports conditioning and in clinical contexts. Contrary to the traditional video analysis, wearable inertial-magnetic measurements units (IMMUs) allow to analyse both the underwater and aerial phases of the swimming stroke over the whole length of the swimming pool. Furthermore, the rapid calibration and short data processing required by IMMUs provide coaches and athletes with an immediate feedback on swimming kinematics during training. This study aimed to develop a protocol to assess the three-dimensional kinematics of the upper limbs during swimming using IMMUs. Kinematics were evaluated during simulated dry-land swimming trials performed in the laboratory by eight swimmers. A stereo-photogrammetric system was used as the gold standard. The results showed high coefficient of multiple correlation (CMC) values, with median (first–third quartile) of 0.97 (0.93–0.95) and 0.99 (0.97–0.99) for simulated front-crawl and breaststroke, respectively. Furthermore, the joint angles were estimated with an accuracy increasing from distal to proximal joints, with wrist indices showing median CMC values always higher than 0.90. The present findings represent an important step towards the practical use of technology based on IMMUs for the kinematic analysis of swimming in applied contexts.

Study on effect of segments erection tolerance and wedge-shaped segment on segment ring in shield tunnel

INTRODUCTION Shield tunnel method has become the most pre- ferred method in city tunnel construction because of its excellent attributes: little effect on surrounding environment, fast and safe construction, outstanding performance in earthquake resistance, etc. (Zhang et al., 2004). In different shield tunnels, the arrangement and number of segments are different, but the whole assembling process is generally the same. The as- sembling process begins with A2P, then A1P, A3P, BP, CP, …
