PHOENIX， the United States， Dec. 25 (Xinhua) -- The southwestern U.S. state of Arizona embraced a friendly attitude toward self-driving test vehicles， as its governor Doug Ducey personally welcomed the first batch of Uber's fleet arriving here Friday.


The car-hailing service provider has turned its attention to Arizona， after the Department of Motor Vehicles of California， where it was originally headquartered， revoked its autonomous vehicle registration last week. Uber decided last Thursday to have its self-driving cars delivered via a self-driving truck to Phoenix， capital of Arizona， for future pilot tests.


While in Arizona， it seems that the governor is seeking a balance between attracting technology businesses and regulatory issues.


Arizona is popular with companies focusing on self-driving technologies， as the Grand Canyon state has less regulations in this regard. Besides Uber， General Motors (GM)， Google and Ford have chosen Arizona as their self-driving test ground.


Although Ducey had asked the Department of Transportation (ADOT) and the Department of Public Safety to come up with rules and regulations for autonomous vehicles， he emphasized that he saw no reason for any special registration for these cars， or for doing nothing until the task force comes up with relevant rules. He just told local media that these cars were to be insured.


Kevin Biesty， ADOT's deputy director for policy， agreed. He was quoted as saying that he understood that the task force would have to deal with questions ranging from whether those behind the wheel of truly autonomous vehicles need to be licensed to who was legally liable if a computer-driven vehicle speeds or causes damage， but the lack of answers to these questions should not preclude the kind of testing that Uber and other companies want to do on Arizona roads.


He added that the Uber autonomous vehicles in their current stage of development do not need special permission or special rules for testing in Arizona.


He took GM's "advanced cruise control" system， which was first tested in Arizona， as an example， saying this system being installed on many GM vehicles had the ability to change the car's speed to avoid accidents.


According to the local newspaper Arizona Capitol Times， Ducey said that Uber's decision to move to Arizona showed the state was more friendly to businesses than its neighbor to the west.


"The message today is Arizona's open for business. We're welcoming this technology. We're not pushing it out of our state，" the governor said.


As more and more companies develop their self-driving cars， safety issues arise， especially after a driver of a Tesla operating on an automated driving system died of a collision with a truck in Florida in May， America's first fatality concerning the new technology.


In Arizona， Google has been testing its self-driving Lexus SUVs for 4 months， while Ford has been conducting road tests for its self-driving Fusion for nearly two years.


40 years ago when I started my career all marble edge polishing was performed by hand. These days such work is accomplished completely by machine but there are still circumstances where hand polishing would be a beneficial skill to know.


Edge polishing at one time existed in an unique semi skilled classification. As a reaction to repetitive motions during their job of rubbing marble Danilo Gallinari Kids Jersey , the employees started to suffer from some deformities, including bulging shoulder muscles.


The edges that needed polish were marked DeAndre Jordan Kids Jersey , beginning the process and the marble slabs, normally from large commercial buildings would be placed on long benches and their patterns were matched. The exposed edges are then marked if they need further polishing.


Each slab would be propped up correctly with the side being polished exposed. Supplies for cleaning would be a bucket of water Chris Paul Kids Jersey , a sponge and a rag cloth.


Start with a coarse 60 or 80 grit stone as the work is to accomplished using a variety of grades of carborundum stone blocks. This would be the longest stage of the work as the edge of the marble would have quite deep ‘wheel marks’ left by the diamond saw blades from the cutting. The stone would be moistened and the rubbed along the edges of the marble. The coarse corners of the marble can be rubbed off to create extremely small flat corner known as arris.


Once in a while the marble had to be dried to check on progress, this was achieved by whirling the rag in the air above the work. This is by far the finest approach to dry large sections of wet stone.


After he has put to use a 60 grit sanding surface to remove all of the wheel marks and deep scratches Blake Griffin Kids Jersey , he will move onto taking care of the second stone with a finer, 120 grit Louis Williams Youth Jersey , sander. Once the grit is removed the stone holds all the scratches left and provides a detail of better finer scratches.


Marble polishing uses increasingly finer grades of sanding materials to remove all visible scratches.


Progressively finer grades of stone was put to use with the finest being 600 grit stone. The final stone made use of was a very fine block created by the polishers themselves from ultra fine carborundum dust and marble glue, and strangely called snake!


The marble surface is still not highly polished at this time. It has just a very smooth honed
