Environomic modeling and optimization of advanced combined cycle cogeneration power plants including CO2 separation options

Considering the economic importance of the electricity generation sector as well as its contribution to local, regional and global pollution, the development of new cost-effective and environmentally benign electricity generation and cogeneration systems i ...

Online throughput-competitive algorithm for multicast routing and admission control

Monika Henzinger, Ashish Goel

We present the first polylog-competitive online algorithm for the general multicast problem in the throughput model. The ratio of the number of requests accepted by the optimum offline algorithm to the expected number of requests accepted by our algorithm ...

Read/write holographic memory versus silicon storage

Demetri Psaltis, Wei Liu

This paper compares the read/write holographic memory with silicon storage on issues of cost, density, size and speed. With a photorefractive crystal on top of a silicon interface, the holographic memory is of cost efficiency, volume compactness and fast d ...

Semi-Passive Replication

André Schiper, Xavier Défago, Nicoleta Sergent

This paper presents the semi-passive replication technique -- a variant of passive replication -- that can be implemented in the asynchronous system model without requiring agreement on a primary (usually done using a membership service). Passive replicati ...

GaAs/GaAlAs heterostructure rib waveguide stepped [Triangle Open]β coupler

René Salathé, Li Wang

GaAS/GaAlAs heterostructure rib waveguide coupler with stepped [Triangle Open]β Schottky electrodes has been investigated by using ion-etching and lift-off mask techniques, and optimization design of device structure and lowering epitaxy layer carrier ...

Actuators and control for teleoperators

The design of a mechatronic system in an industrial context is alwais affected by cost. Either the performances have to be optimized for a given cost or the cost must be minimized for the given performances. ...

Metal clusters with impurities: NanMg (n = 6-9, 18)

Wanda Andreoni

The authors det. structural and electronic properties of NanMg clusters using the Car-Parrinello method. The low-energy isomers, which result from a dynamical simulated annealing search, can be described as substitutionally doped Na clusters. The Mg impuri ...

Linear programming applied to reactive power flow optimization in high voltage power systems

Linear programming application for optimal active power flow under constraints shows very good results, without causing particular problems. However, the same technique is more difficult to apply to reactive power optimization, due to the nonlinearity of r ...

Wind Farm Layout Optimization using Genetic Algorithms with a Gaussian Wake Model

Fernando Porté Agel, Nicolas Otto Kirchner Bossi

In this work we have designed and implemented different Genetic Algorithms especially adapted to the Wind Farm Layout Optimization (WFLO) problem, with the goal to optimize the overall power output and electricity cable length of different Wind Farms curre ...

Does Austerity Go Along with Internal Devaluations

Luisa Lambertini, Christian Pröbsting

We empirically show that the austerity packages implemented in some euro area countries during 2010–2014 were only partially successful in generating internal devaluations. Countries that cut spending indeed experienced a decline in nominal wages, a real e ...
