MeerKAT - The South African Array With Composite Dishes and Wide-Band Single Pixel Feeds
| The MeerKAT is a precursor for the Bsmall dish plus single-pixel wide-band feed[ scenario for the Square Kilometre Array (SKA). The current goal specification is for an array of 80 12-m dishes operating over a continuous frequency range of 0.7–10 GHz, thus the individual receptors match the SKA draft specification for midband dishes. The proposed array configuration is centrally concentrated ...
متن کاملDynamic Frequency Scaling Schemes for Heterogeneous Clusters under Quality of Service Requirements
Nowadays, both the performance and power consumption for modern server clusters and data centers must be considered to reduce the maintenance cost for quality of service guarantees, as power dissipation affects the cost of both the power delivery subsystems and cooling facility. Considering the popularity of heterogeneous clusters, this paper proposes efficient and effective power management sc...
متن کاملScaling of swim speed and stroke frequency in geometrically similar penguins: they swim optimally to minimize cost of transport.
It has been predicted that geometrically similar animals would swim at the same speed with stroke frequency scaling with mass(-1/3). In the present study, morphological and behavioural data obtained from free-ranging penguins (seven species) were compared. Morphological measurements support the geometrical similarity. However, cruising speeds of 1.8-2.3 m s(-1) were significantly related to mas...
متن کاملTaking the ANU Big Dish to commercialization
The ANU 400m “Big Dish” is familiar to most people in the Renewable Energy Community. The first prototype was completed in 1994 and research and development aimed at supporting and improving the technology has continued within the ANU Solar Thermal Group since then. In 2005, Wizard Power Pty Ltd was established by a Canberra investor in order to take the Big Dish technology to commercial deploy...
متن کاملMMA Memo 207: Wide Bandwidth, YIG-Based Sources and Modern Frequency Multipliers for the MMA Local Oscillator System
The conventional approach to generating local oscillator (LO) power for millimeterand submillimeter-wave heterodyne mixers is to generate power at a lower frequency using a suitable phase-locked source, and to convert this power to the desired commensurate frequency using a nonlinear diode such as a varactor in a frequency multiplier circuit. Although useful for single-dish telescope receiver s...
