The success of server virtualization has let to the deployment of a huge number of virtual machines in today's data centers, making a manual virtualization management very laborintensive. The development of appropriate management solutions is hindered by the various management interfaces of different hypervisors. Therefore, a uniform management can be(More)
inverting large lecture classes and then presents our approach for this particular class. We also employed Pingo (Peer Instruction for Very Large Groups). 5. "The design of buildings and cities in the arctic is in large part a legacy of Two categories of manuscripts will be accepted for peer review: For further information for manuscript preparation, please(More)
In this research, we introduce a web-based open source solution that enables the transfer of the widely established Peer Instruction approach to lectures with in excess of 350 participants. The proposed solution avoids several existing technical flaws that currently hinder the further adoption of Peer Instruction. We test our solution in a series of(More)
Exclusive production of 0 and J== mesons in e + p collisions has been studied with the ZEUS detector in the kinematic range 0:25 < Q 2 < 50 GeV 2 , 20 < W < 167 GeV for the 0 data and 2 < Q 2 < 40 GeV 2 , 50 < W < 150 GeV for the J== data. Cross sections for exclusive 0 and J== production have been measured as a function of Q 2 , W and t. The spin-density(More)
Classroom response systems (CRSs) have proven to turn students into active participants in lectures. Thus, these systems help to improve the students' learning performance in traditional head-on lectures. Peer Instruction is a teaching and learning approach that makes very specific use of Classroom Response Systems elements: similar to the ask-the-audience(More)
The e + p neutral-current deep inelastic scattering diierential cross-sections dd=dQ 2 , for Q 2 > 400 GeV 2 , dd=dx and dd=dy, for Q 2 > 400, 2500 and 10000 GeV 2 , have been measured with the ZEUS detector at HERA. The data sample of 47.7 pb ?1 was collected at a center-of-mass energy of 300 GeV. The cross-section, dd=dQ 2 , falls by six orders of(More)
In inductive heating applications, high-power single-phase loads, e.g. for melting furnaces, are used. Usually, they are connected to an inverter that provides the appropriate voltage and frequency. In contrast to three phase loads, the power oscillates at twice the operation frequency. To ensure a constant power extraction from the supply grid, the(More)
