Abstract: System and method for controlling energy consumption in a data center. An embodiment includes: segregating hot air from cold air by preventing hot air exhausted from hot aisles from flowing into cold aisles; measuring temperature and relative humidity values of the segregated hot and cold air; detecting temperature and relative humidity values of outside air; mixing the segregated hot air with a volume of the outside air, the volume of the outside air depending on a result of the measuring and the detecting; measuring temperature and relative humidity values of the mixed air; comparing the temperature and relative humidity values of the mixed air and the temperature and relative humidity values of the segregated cold air to IT specifications; cooling the mixed air based on a result of the comparison; and providing the cooled mixed air in the cold aisles.

Abstract: A tire designed to be mounted on a mounting rim J of maximum diameter Dc the type comprising beads designed to cooperate with seats of the mounting rim, the beads comprising at least one annular bead reinforcement structure; a crown comprising a reinforcement structure, this crown being surmounted radially on the outside by a tread; on either side of the tire's crown, a sidewall providing connection to each bead; a carcass reinforcement extending between the crown and the beads; wherein at least one sidewall comprises at least two additional annular reinforcement structures, each additional annular structure having an inner diameter at least equal to the maximum diameter Dc of the rim; the carcass reinforcement is anchored at least partially on each annular bead reinforcement structure and on each additional annular sidewall reinforcement structure; the difference between the inner diameter of the radially innermost additional annular reinforcement structure in each sidewall and the diameter Dj of the rim sea
