一 | Kyiv, Oct 18 (UNI) Russian forces have again targeted Ukraine's energy facilities, leaving part of Kyiv and other cities with no power and water.
Explosions were heard in the capital shortly after 9 am and plumes of smoke billowed from around a power station near the Dnipro river, the BBC reported.
Power and water were cut in Zhytomyr, west of Kyiv, and two facilities were badly damaged in Dnipro.
The latest attacks came 24 hours after Kyiv was hit by "kamikaze" drones on Monday.
The unmanned drones, believed to be Iranian-made, killed at least five people in the capital and four in the northern city of Sumy, and struck critical infrastructure, with power outages reported in hundreds of towns and villages.
Russia has stepped up attacks in recent weeks on electricity infrastructure in cities away from the front lines.
Officials have rushed to repair the damage, but the strikes, ahead of winter, have raised concerns about how the system will respond, the BBC said.
"Ukraine is under fire by the occupiers. They continue to do what they do best - terrorise and kill civilians," said President Volodymyr Zelensky in response to the attacks.
It was not initially clear to what extent drones were involved, although Kyrylo Tymoshenko, deputy head of the presidential office, said an S-300 anti-aircraft missile was fired at a residential building in the southern city of Mykolaiv overnight, killing one person. The city's flower market was also destroyed.
Early on Tuesday, the Zhytomyr mayor said there was no power or water in the city and hospitals were working on back-up power.
Power and water supplies were also disrupted in the central city of Dnipro and officials appealed to residents to use power sparingly
Shelling was reported in the north-eastern city of Kharkiv. Infrastructure in the southern city of Zaporizhzhia was also hit, although local officials said no-one had been hurt.
In some cities, Ukrainians are buying power generators and gas burners, while across the country, people have been urged to reduce their energy consumption at peak times. Some towns are already facing rolling blackouts, the BBC report added.
The latest attacks, by both missiles and drones, have brought renewed calls from the Ukrainian government for the delivery of air defence missiles.
UNI ING。 8 月 26 日消息，“绿色地狱”纽博格林赛道是车手证明实力、刷新圈速纪录的圣地。
二 | 不过，越来越多的汽车制造商开始将纽博格林视为自动驾驶技术的试验场。
三 | 小米在今年夏天率先展开尝试，一辆搭载自动驾驶技术的小米 YU7 GT 用 10 分 29.483 秒完成了一圈，达成全球首个纽北自动驾驶圈速纪录。这个成绩比人工驾驶的同款车型慢了 3 分多钟，但对于一辆自动驾驶汽车来说，这样的表现已经相当不错。如今，梅赛德斯-AMG 似乎也准备加入这一行列。近日，谍照摄影师拍到一辆 GT 63 原型车正在进行测试。
四 | 乍看之下，这辆车与普通车型并没有太大区别，但车顶上安装了三个传感器。
五 | 此外还可以看到，车内“驾驶员”特意将双手放在方向盘之外。
六 | 据谍照摄影师透露，这辆原型车首先以非常缓慢的速度沿着赛道最右侧行驶，用于完成赛道的圈速测试和地图采集。整个过程大约耗时 25 分钟，随后车辆又切换到赛道最左侧，重复进行圈速测试和地图采集。在确定赛道两侧边缘的位置后，这辆原型车终于做好了完全脱手驾驶的准备。
七 | 第一次自动驾驶正式跑圈时，车辆完成了一个“非常缓慢且谨慎的圈”。据报道，车辆整体驾驶风格十分保守，加速受到严格控制，并且会提前进行制动。这一圈耗时不到 20 分钟，车内“驾驶员”全程只是为了在出现问题时进行干预。成功完成测试后，车辆返回维修区，让工程师分析采集到的数据，并进一步调整车辆的相关设置。随后，这辆原型车再次驶上赛道进行第二圈测试，完成时间比第一圈“快了几分钟”。不过，据报道，这一成绩“距离小米创下的纪录还差得很远”。据了解，梅赛德斯-AMG 似乎在完成第二次测试后暂时结束了此次测试。不过毫无疑问，该公司将仔细分析这次测试获得的数据，并从中总结经验。预计这辆原型车未来会再次出现在纽博格林赛道，并尝试创造属于梅赛德斯-AMG 自己的自动驾驶圈速纪录。
