2Weibull analysis of fluidity and hardness of ultrasonical y degassed secondary Al7Si0.3Mg aluminum alloy显示文摘The influence of ultrasonic degassing process on fluidity and hardness of secondary Al7Si0.3Mg alloy castings was studied by Weibull analysis. This work makes a contribution about fluidity and hardness distribution of secondary aluminum alloys with ultrasonic degassing phenomena using a two-parameter form of Weibull analysis. Results show that both hardness and fluidity of alloy are improved after the ultrasonic degassing process. Average efficiency of ultrasonic degassing on fluidity measurements is 31.71%, whereas on hardness values is 8.48%. The Brinell hardness of 45.7 and fluidity of 19.5 of Weibull modulus were achieved as the most reliable and reproducible after 45 s ultrasonic degassing process against 15 s and 30 s ultrasonic degassing processes. The value of 70.08 HB is obtained from ultrosonic degassing, which is equivalent to sand casting of primary Al7Si0.3Mg aluminum alloy, and the highest value of 56.4 cm for 45 s after ultrasonic degassing of fluidity was measured.?a?lar Yüksel 2019China Foundry2019,16,5:2

6织物表面粗糙度测试仪的新应用显示文摘本研究利用一种表面粗糙度测试仪测试面料的粗糙度,这种仪器没有应用到纺织测试的先例。测试的对象包括羊毛和羊毛/涤纶混纺织物。由专家委员会做主观粗糙度测试,同时由他们来确定手感评价。用斯皮尔曼相关分析法研究主观和客观粗糙度测试结果间的关系,并选择与主观测试最关联的粗糙度参数。选择三个粗糙度参数,用方差分析法分析这些参数对测试结果的影响因素。进行重复试验,对不同组织的织物进行测试。本文的目的是开发一种实用的表面粗糙度的测试方法并应用于客观的手感评价上。Vildan sülar Ayse Okur 2010中国纤检2010,,14:0

9Anticipation and Response: Emergency Services in Severe Weather Situations in Germany显示文摘Communicating meteorological uncertainty allows earlier provision of information on possible future events. The desired benefit is to enable the end-user to start with preparatory protective actions at an earlier time based on the end-user's own risk assessment and decision threshold. The presented results of an interview study,conducted with 27 members of German civil protection authorities, show that developments in meteorology and weather forecasting do not necessarily fit the current practices of German emergency services. These practices are mostly carried out based on alarms and ground truth in a superficial reactive manner, rather than on anticipation based on prognoses or forecasts. Emergency managers cope with uncertainty by collecting, comparing, and blending different information about an uncertain event and its uncertain outcomes within the situation assessment to validate the information. Emergency managers struggle most with an increase of emergency calls and missions due to the impacts of severe weather. Because of the additional expenditures, the weather event makes it even harder for them to fulfill their core duties. These findings support the need for impact-based warnings.Thomas Kox Catharina Lüder Lars Gerhold 2018International Journal of Disaster Risk Science2018,9,1:2
