An improvement in the algorithm for assigning vertex(es) as graph center(s) is achieved on the basis of the distances between vertexes and between edges, as well as proceeding from the vertex-edge incidence. The iterative vertex and edge centricities (IVEC) algorithm produces assignments that are in better agreement with the intuitive notion of graph center than those produced by the previous p...

The increasing awareness of the impact of the IT sector on the environment, together with economic factors, have fueled many research efforts to reduce the energy expenditure of data centers. Recent work proposes to achieve additional energy savings by exploiting, in concert with customers, services’ workloads and to reduce data centers’ carbon footprints by adopting demandresponse mechanisms b...
We study the 1-center problem with outliers in highdimensional data streams. The problem definition is as follows: given a sequence of n points in d dimensions (with d arbitrarily large), enclose all but z points using a ball of minimum radius.
The World Data Center (WDC) for Geophysics, Beijing, was founded in 1988. Supported by The Chinese Academy of Science and The Ministry of Science and Technology, our center has made much progress in recent years. The center has not only established the database to restore data which contain heat flow data, geomagnetic data, gravity data, etc. but also put them on the Internet (http://gp.wdc.cn)...
Multi-tenant datacenters represent an extremely challenging networking environment. Tenants want the ability to migrate unmodified workloads from their enterprise networks to service provider datacenters, retaining the same networking configurations of their home network. The service providers must meet these needs without operator intervention while preserving their own operational flexibility...
Data centers are large energy consumers and a substantial portion of this power consumption is due to the control of physical parameters, which bring the need of high efficiency environmental control systems. In this paper, we describe a hardware sensing platform specifically tailored to collect physical parameters (temperature, pressure, humidity and power consumption) in large data centers. T...
By employing a nonlinear quantum kicked rotor model, we investigate the transport of energy in multidimensional quantum chaos. This problem has profound implications in many fields of science ranging from Anderson localization to time reversal of classical and quantum waves. We begin our analysis with a series of parallel numerical simulations, whose results show an unexpected and anomalous beh...
