  • Research on joint generation scheduling of cascade hydro plants in the dry season

    As more and more reservoirs are built, concentrated water releasing in the dry season will bring about additional flow compensation and the joint operation of cascade hydro plants is quite important. This paper discusses the water level decline strategy of four cascade hydro plants in the Jinsha River and analyses the relationship between guaranteed output and total power generation. ...

  • Understanding India-Pakistan water politics since the signing of the Indus Water Treaty

    On 19 September 1960, the Indus Water Treaty (IWT) was signed between India and Pakistan, presumably resolving the conflict of Indus water sharing. Nevertheless, over the years the conflict has re-appeared, dragging both the riparian states into confrontation. This paper explores the reasons that lead to conflict despite the Indus water sharing having already been resolved by the IWT. Analysis ...

  • Side Core Pulling Mechanism

    The flanks of plastic parts are usually provided with holes or flutes. Under such conditions, side-direction forming cores must be used to form plastc parts. However, such cores must be developed into active parts so that they can be pulled out prior to the stripping of plastic parts. The mechanism for pulling out and restoring such active cores is called  ...

  • Multi–physics modelling of nuclear reactors: current practices in a nutshell

    Current practices in the nuclear industry to model the transient behaviour of nuclear reactors are based on the use of different solvers for resolving the different physical fields, and to some extent the different scales. The overall time–dependence is computed by a coarse–mesh neutronic solver coupled to a coarse–mesh thermal–hydraulic solver. The meso–scale information in the thermal–hydraulic ...

  • Tidal Power Source

    I imagined some new technique and I want to introduce it. This is only an ideology and not experimented yet. If anybody wants to experiment this i have no objection. According to me any technology that helps the mankind must be universal. I don’t want like anybody’s monopoly on this technology. I wish this technology should be experimented and make this available to generate power, ...

  • Cameroon`s infrastructure : a continental perspective

    Better access to improved infrastructure services is an important engine for economic growth. The poor state of infrastructure is a key bottleneck to growth in African countries, and Cameroon is no exception. Between 2000 and 2005, improvements in information and communication technologies boosted Cameroon's growth performance by 1.26 percentage points per capita, while deficient power ...

  • Web–based post–processor for RELAP5: a development based on LabVIEW

    This work presents the development of a LabVIEW web–based post–processor for the RELAP5 output. A RELAP5 model was developed for the thermal–hydraulics experimental facility, called Natural Circulation Circuit. A Visual Basic for application program (Xtrip) was developed to transform binary data file from RELAP5 in an ASCII file. This new output file can be displayed in user–friendly Graphical ...

  • Comparative control analysis of the Vienna rectifier based on its averaged model

    This paper presents a comparative evaluation of two multiple-loops duty-cycle-based control schemes applied to a three-phase three-switch three-level boost-type rectifier. The control laws are both elaborated on the basis of a state-space averaged model of the converter, expressed in the synchronous rotating frame. On the one hand, a control scheme that uses linear regulators is designed by using ...

  • Public-Private Sector Partnership on Hydropower in the Partner Countries

    This project will support the Task Force in its effort to create an enabling environment for renewable and distributed generation technologies in Partner countries. The project will focus on all Partner countries in order to identify specific barriers impeding hydropower investment in each country. Partner countries have identified more than $200 billion in hydropower investment necessary for ...

  • Laser Doppler vibrometer for mode shape and power flow analysis in coupled structures

    In this paper, an experimental technique is introduced to investigate the structural response under impact loads, which consists of the waveform measuring technique in the time domain by using the WAVEVIEW software, and steady-state measurements by using the Polytec Laser Scanning Vibrometer (PLSV) in the frequency domain. The waveform measuring technique is introduced to obtain the waveform at ...

  • Power excursion of the training and research reactor of Budapest University

    A three-dimensional neutronic code POWEX-K has been developed, and it has been coupled with the subchannel thermal-hydraulic core analysis code MI based on the momentum integral model. This forms the integrated neutronic/thermal hydraulics code system POWEX-K/MI for the accident analysis of the training and research reactor at the Budapest University of Technology and Economics (BME Reactor). An ...

  • Energy Efficiency is PRO Business

    There is a lot of current debate about whether the State of WA should require utilities to make greater investments in energy efficiency. This has caused some waves within the business community which has legitimate concerns about energy prices and is usually in opposition to government mandates and. Although not proven, the common belief amongst businesses is that laws requiring investments in ...
