European Union Issues World’s First Comprehensive Regulations for Artificial Intelligence

作者： chris Palmer senior Technology Writer

In March 2024,European Union(EU)lawmakers passed the world’s first comprehensive set of regulations governing the use of artificial intelligence(AI)[1].The EU’s AI Act,two and a half years in the making,was initially drawn up as a landmark bill to reduce harm in areas in which AI was thought to pose the biggest risks to people,such as in health care,education,and security,as well as banning uses that pose“unacceptable risks,”including manipulation of human behavior and evaluation of individuals’trustworthiness based on personal *** to the regulations,which will go into effect in stages over the next two years,“high-risk”AI systems will require risk-mitigation strategies,high-quality data sets,transparency,better documentation,and human *** most common current AI uses,such as augmenting recommendation engines and email spam filters,will see far less oversight.

This paper presents an analytical approach for estimating frictional resistance to pipe movement at soil and external pipe surface of buried coated pressurized steel pipes relative to the internal thrust *** proposed analytical method was developed based on 36 experiments,which involved three coating types(cement mortar(CM),polyurethane type-I(PT-I),prefabricated plastic tape(PPT))on pipes’surfaces,three different soils(pea-gravel(PG),sand(s),silty-clay(sC)),and four simulated over burden depths above the pipe’s *** showed frictional resistance decreased with increasing over burden depth above the pipe’s *** degree of frictional resistance at the pipe-soil interface was found to be in the order of PG>sC>s for all coating variations and overburden *** coated pipe buried in all three types of soil produced significantly higher frictional resistance as compared to other coating *** on experimental data,the developed analytical introduced a dimensionless factor“Z”,which included effects of types of coatings,soil,and overburden depths for simplified rapid *** showed that the method provided a better prediction of frictional resistance forces,in comparison to previous analytical methods,which were barely close in predicting friction resistance for different coating variations,soil types,and overburden *** resistance force values reported herein could be considered conservative.

As reported in a study published in April 2023,some of the globally banned chemicals that decimated the Earth’s ozone layer are still finding their way into the atmosphere[1].While unlikely to greatly impact global ozone levels,the continuing pollution has scientists concerned for two reasons:The chemicals,called chlorofluorocarbons(CFCs),are potent greenhouse gases,and,perhaps more worrying,the sources of the surprising emissions remain unidentified.

In April 2023,a satellite orbiting approximately 500 km above Earth’s surface delivered terabytes of data at record-breaking rates of up to 200 Gb·s^(-1)—more than 100 times faster than the fastest internet speeds in most cities—via an optical communication link to a ground-based receiver 95 km north of Los Angeles,CA,UsA[1].At more than 1000 times faster than the radiofrequency(RF)links traditionally used for satellite communication,this is the highest data rate ever achieved for a space-to-ground optical transmission[1].
