Pavel Prikhodko, Ph.D. Machine Learning

Cement is one of the world’s key building materials, both in the residential and non-residential sectors. This material is also used in the production of concrete. Thus, over 70 percent of cement sales in the United States were made to producers of ready-mixed concrete, and about 12 percent of sales went to concrete product manufacturers. According to information published at Statista.com, around 4,100 million metric tons of cement were produced globally in 2015. The U.S. accounted for about 83.4 million metric tons of this production. The year before, 4,180 million metric tons of material were produced worldwide, and 83.2 million metric tons were produced in the U.S. In 2013, these numbers decreased: 4,080 million metric tons globally and about 77.4 million metric tons in the U.S.

Pavel Prikhodko, Ph.D. Machine Learning

According to the United States Census Bureau data for 2008-2012, more than half of all Americans commute to work every working day. Personal cars and public transportation are not the only modes of commuting, but they are the most popular. Year after year, walking and cycling are becoming more and more popular, and the corresponding infrastructure is developing rapidly. While it may not be for everyone, walking and cycling do have a few advantages over motorized travel. They are healthier, ecologically pure and require less expensive infrastructure than other methods of commuting. Of course, the distribution of the number of pedestrians and bicyclists across the states is not uniform. Ithaca, NY has the highest percentage of walkers in the country, while Portland, OR has the highest percentage of cyclists.
