THERMOPHILIC BIOMETHANE PRODUCTION BY VINASSE IN AN AnSBBR: START-UP STRATEGY AND PERFORMANCE OPTIMIZATION

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

Biomethane production from vinasse in upflow anaerobic sludge blanket reactors inoculated with granular sludge

The main objective of this study was to evaluate the anaerobic conversion of vinasse into biomethane with gradual increase in organic loading rate (OLR) in two upflow anaerobic sludge blanket (UASB) reactors, R1 and R2, with volumes of 40.5 and 21.5L in the mesophilic temperature range. The UASB reactors were operated for 230 days with a hydraulic detection time (HDT) of 2.8d (R1) and 2.8-1.8d ...

Optimizing TCP Start-up Performance

The performance of many networking protocols is dependent on a handful of tuning parameters. However, it is not obvious how to set or adapt these parameters to optimize performance. We believe that this optimization task can benefit from passive monitoring of current network performance. In this paper, we apply this methodology for initializing TCP parameters, such as initial congestion window ...

Managing inventory and production capacity in start-up firms

Successful start-up firms make a valuable contribution to economic growth and development. Models that provide insight into the management of start-up firms are therefore important. We consider the problem of managing inventory and production capacity in a start-up manufacturing firm and argue that for such firms the objective of maximising the probability of the firm surviving is more appropri...
