A PWM controller is designed for the active suspension without external energy supply (ASWEES) using the LQG control method. Based on the quarter-vehicle ASWEES model, Energy flow equation between the suspension and the accumulator with a 2 kW load was deduced and a PWM controller was designed. When 200Hz solenoid valves were adopted, the carrier frequency and series value of the carrier signal were set as 40 and 5 respectively. Simulation results show the suspension quadratic performance index of ASWEES decreases 24.97% than that of the passive suspension. The passive suspension consumes 2.211kW power, but ASWEES reclaims energy of 2 kW.

Abstract A modified Peierls-Boltzmann transport equation formalism for phonons is applied to Fröhlich’s vibrational model. In this model a set of oscillators it nonlinearly coupled to the rest of the system, which can be taken as a heatbath. An external energy supply leads to an additional excitation of the modes. The Hamiltonian for the model is presented and the kinetic equations are derived. The steady state solutions show that under certain conditions the lowest mode be-comes strongly excited, when the phonon flux increases. The resulting excitation far above the thermal value corresponds to a preferred channeling of energy into a single mode (Bose condensation-like excitation). Correspondence with Fröhlich’s rate equation approach is established and the quasi phase transition-like behaviour is discussed

The studies of acting of pulsed-periodic energy supply on the transonic flow regimes of streamline of the body of revolution were performed for different models of the energy source. The possibility of a significant restructuring of the flow, which can serve as a basis for effective control of streamline of as a whole aircraft and its components was demonstrated

External energy relations are essential components of both the European Union’s search for an overall energy strategy, an Energy Policy for Europe (EPE) and the development of the European Neighbourhood Policy (ENP). In this article questions are posed about the role for the use of nuclear technology as the means of meeting some of the objectives of both areas of policy. As both the EPE and the ENP are dependent on the negotiation of international agreements with third parties for their effectiveness the focus of analysis presented will be on the EU’s legal and constitutional framework for action and in particular the EURATOM Treaty which established the European Atomic Energy Community in 1957.

At Hamburg's Köhlbrandhöft WWTP the demand for external energy supply is minimised by state of the art sludge treatment. The sludge is subjected to thickening, anaerobic digestion, dewatering, drying and incineration. The digester gas is used in a combined gas and steam turbine process. The sludge incineration also produces steam, which is also used in the steam turbine that follows the gas turbine. The turbines produce electricity, partially expanded steam is used for the sludge drying process. Heat from the condensation of vapours from sludge drying is used to heat the anaerobic digesters. The overall process requires no external heat or fuel and produces 60% of the WWTP's electricity demand.

To fully understand a technological development one must appreciate social, political and economic factors in addition to the technological components (Hughes, 1991). The systems perspective, asserted by Hughes, implies that technologies cannot be understood in isolation, but only in their contexts, especially in their systemic contexts. This theory is illustrated through an examination of France’s implementation of its nuclear power program in the early 1970’s. Nuclear power provided France with the opportunity to achieve energy independence and, as a result, political control over its energy supply. The scope of this case study is limited to consideration of the socio-technical influences on the rise of nuclear power in France and includes an examination of the technical aspects of the innovation. In considering the socio-technical system encompassing France’s adoption of nuclear power, this case study will contemplate: how France was able to persuade its people to accept nuclear power; what it is about French culture and politics that allowed them to succeed where most other countries have failed; the break throughs that led to the broad commercialisation of nuclear power in France in the 1970’s; and how France achieved its status as one of the world’s top producers of nuclear energy. The time period during which this study is based is limited to the early 1970’s, when France was reliant upon external energy supplies, up until the present day, where nuclear power has become France’s main source of energy, thus contributing to France’s autonomy in terms of its energy supply. This study will not address the issue of nuclear waste or the nuclear power safety debate which is also beyond the scope of this study.
