Decentralized water reclamation is emerging as a new paradigm that pairs local wastewater resources with local users; however, one of the challenges that must be addressed to advance its implementation is the low energy efficiency associated with small treatment plants and the lack of available small-scale energy recovery technologies. Gasification is a technology that could be used to convert ...

Income growth and industrialization of the developing countries is driving their economies towards the use of secondary energy forms that deliver high efficiency energy and environmentally improved end-uses for biomass. Typical of these secondary energy forms are electricity, distributed gas systems, and liquid fuels. This trend suggests that the hitherto separate biomass energy technology deve...

Now, more than ever before, the use of renewable energy is critical to the well being of our planet. Solar energy, in particular, is one of the main sources of renewable energy and the subject of research worldwide. While most renewable energy projects using solar energy target large-scale applications, renewable energy technologies are also suited for small-scale applications. This is evident ...

In this paper, using energy method, small scale effects on the buckling analysis of a double-walled carbon nanotube (DWCNT) under external radial pressure is studied. The constitutive equations derived for a DWCNT using the nonlocal theory of elasticity which Eringen are presented for the first time. By minimizing the second variation of the total energy for a DWCNT, hence, the value of the non...

A mathematical connection is established between the ocean near-surface geostrophic kinetic energy and the small-scale variance of its surface height. The latter is defined as the spatial variance of sea surface height inside a given grid box and represents a basic statistical characteristic of the field, necessary for estimating its vulnerability to sampling error. The former is also computed ...

Magnetic fluctuations in the solar wind are distributed according to Kolmogorov’s power law f below the ion cyclotron frequency fci. Above this frequency, the observed steeper power law is usually interpreted in two different ways: a dissipative range of the solar wind turbulence or another turbulent cascade, the nature of which is still an open question. Using the Cluster magnetic data we show...

This study reports on the findings from the investigation into small-scale (6.25 mL) MFCs, connected together as a network of multiple units. The MFCs contained unmodified (no catalyst) carbon fibre electrodes and for initial and later experiments, a standard ion-exchange membrane for the proton transfer from the anode to the cathode. The anode microbial culture was of the type commonly found i...

I consider the next-to-leading high-energy cluster expansion of large-k double jet production in QCD, and I determine the corresponding one-loop quark and gluon impact factors for a self-consistent energy scale. The result shows that coherent angular ordering of emitted gluons holds for hard emission also, and singles out a scale which in essentially the largest virtuality in the process. Both ...

Green computing has received significant attention in the past few years. Although some research has addressed cooling and energy usage reduction in large data-centers [1], they do not control how resources are used by applications. Scientific workflows are a useful representation for managing the execution of large-scale computations on high performance computing (HPC) and high throughput comp...
