Regenerative braking energy feedback system (RBEFS) can effectively feed the regenerative braking energy (RBE) of the trains back to the ac power grid. This improves the economy of the urban rail transit system greatly. The RBEFS that is utilized for both recycling the RBE and controlling the voltage of the traction network is proposed in this paper. First, the structure of …

Eco-feedback systems operate on the premise that building occupants are largely unaware of how much energy they consume on a day-to-day basis [4], and once occupants …
tion and secure communication [6–10] based on the chaotic series. On the other hand, control of chaos and hyperchaos became attractive because chaotic behav-ior could be harmful in some cases. As a result, many schemes have been proposed to stabilize the chaos and thus arbitrary target orbits can be reached [11–14]
This report gives the particulars about the design of a small scale brick kiln that uses coffee husks as source fuel. All the information contained in this report was obtained through research carried out about the history of brick kilns, types of existing brick kilns, their impact on the environment, their construction, cost of setting them up, existing fuel sources, their calorific values ...
Rising global energy demand, increasing electricity prices, and the limitation of natural resources have led to increased interest in energy monitoring of residential buildings. Much research has …
1. Introduction reduce their environmental impact [6]. Since research has shown that feedback alone is not enough to influence behaviour change [7], many studies on eco-feedback leverage a wide range of techniques from environmental and social psychology such as comparison, goal-setting, competition, and reward [6].
An Eco-feedback system provides building occupants with information about their historical and current energy usage through technology (device and/or interface). Such …
Energy feedback systems (EFSs) have been widely applied in urban rail transit, and a power flow algorithm and energy-saving evaluation of urban rail power supply systems with EFSs are studied in this paper. First, trains, the reflux system, and traction substations with EFSs are modeled, and the multimode transitions are analyzed, including the maximum power state of the EFS. Then, …
Blood pressure is a regulated variable that leads to the heart increasing its rate (i.e. heart rate increases) and contracting more strongly. These changes to the heart cause it to need more oxygen and nutrients, but if the blood volume in the body is too low, the heart tissue itself will not receive enough blood flow to meet these increased needs.
Introduction. T here are many different control mechanisms that can be used, both in everyday life and in chemical engineering applications. Two broad control schemes, both of which encompass each other are feedback control and feed-forward control. Feedback control is a control mechanism that uses information from measurements to manipulate a variable to …
2.1 Promoting Sustainable Energy Use Through Feedback. Research in psychology has extensively studied feedback and its impact on behavior change (for an overview, see []).Feedback is commonly understood as "the process of giving people information about their behavior that can be used to reinforce and/or modify future actions" [] the context of energy …

In the dc electric railways, when a train regenerates power, usually the power has to be consumed within the dc network because the dc traction power systems are often not reversible. Several technologies improve receptivity: energy consumption, energy feedback, and energy storage. Solution selection depends on the application. The energy feedback systems (EFSs) convert …
