When we throw out our trash it is burned in an incinerator or buried in a landfill. If we burn our trash, it pollutes the air. If we bury it, it fills up our landfills and gets out of hand. But ifwe recycle things, it will not pollute anything and we can use it over again. By recycling we also save money. Our county has a recycling program. Every Friday, you have a chance to put out your trash ...

In making alternative fuels from biomass feedstocks, the production of butyric acid is a key intermediate in the two-step production of butanol. The fermentation of glucose via Clostridium tyrobutyricum to butyric acid produces undesirable byproducts, including lactic acid and acetic acid, which significantly affect the butyric acid yield and productivity. This paper focuses on the production o...

Peaked density profiles may not only improve confinement properties, but also give the additional benefits of increased fusion production and ignition margin in BPX, as shown in Fig. 8.1. The ability to control density profiles in the core and scrape-off regions is governed by a number of both physics and operational considerations that make it difficult to specify optimized fueling systems. Fo...

This paper proposes a control system for integrated pressure and surge control of centrifugal compressors for enhanced oil recovery application. The proposed control system is based on linear model predictive control. A fully validated non-linear dynamic model was developed in order to simulate the operation of the compressor at full and partial load. The model of the compression system include...
