JUNO’s investigation focuses on four themes: origin, interior structure, atmospheric composition and dynamics, polar magnetosphere. Using a spinning solar-powered spacecraft, the Juno equipment will obtain global maps of the gravity, magnetic fields, and atmospheric composition of Jupiter from a unique polar orbit with a close perijove. JUNO carries in fact precise, high-sensitivity radiometers...

Purpose – The purpose of this paper is to explore the use of the purchase power of the higher education system to catalyze the economy of scale necessary to ensure market competitiveness for solar photovoltaic electricity. Design/methodology/approach – The approach used here was to first determine the demand necessary to construct “Solar City factories”, factories that possess equipment and pro...

A 2-element Michelson radio interferometer was installed at Bleien observatory. The main task of the experiment was on the one hand the demonstration of a solar interferometer with low cost components, on the other hand to compare different radio spectrometers as a backend for the interferometer. Furthermore, we tried to optimize the equipment to find the limits of the instrumental setup concer...

The lack of readily available sterilization processes for medicine and dentistry practices in the developing world is a major risk factor for the propagation of disease. Modern medical facilities in the developed world often use autoclave systems to sterilize medical instruments and equipment and process waste that could contain harmful contagions. Here, we show the use of broadband light-absor...

We propose to use low-cost optics equipment in order to (1) generate a Hertzsprung-Russell diagram for the 24 brightest stars visible in Beaumont, (2) analyze the polarization of stellar and solar light and the effect a telescope's optics have on these measurements, and (3) analyze the absorption spectrum due to Earth’s atmosphere on the Sun’s blackbody radiation spectrum.

Equipment and techniques employed in an airborne far ir (80-400 micro) spectral measurement of the solar brightness temperature are described, with particular attention paid to the scanning Michelson interferometer and the radiometric calibration. The airborne performance of several telescopic guiding systems, a liquid helium cooled bolometer, and golay cells are discussed, summarizing experien...

The solar energy e-learning laboratory (solar elab) in Cyprus is a good example of a web-based, remote engineering laboratory. It comprises a pilot solar energy conversion plant which is equipped with all necessary instrumentation, data acquisition, and communication devices needed for remote access, control, data collection and processing. The impact that the solar e-lab had during its nearly ...

Energy generated by the force of water in hydropower can provide a more sustainable, non-polluting alternative to fossil fuels, along with other renewable sources of energy, such as wind, solar and tidal power, bio energy and geothermal energy. Small scale hydroelectricity in Iran is well suited for “off-grid” rural electricity applications, while other renewable energy sources, such as wind, s...

More than half the energy to run a data center can be consumed by vapor-compression equipment that cools the center. To reduce consumption and recycle otherwise wasted thermal energy, this paper proposes an alternative cooling architecture that is heat driven and leads to a more efficient data center in terms of power usage effectiveness (PUE). The primary thermal source is waste heat produced ...
