A multi-objective multi-sectoral economy–energy–environment model: Application to Portugal

Portugal is faced with important challenges concerning the definition of policies to achieve energy and environmental targets, taking also into account the economic and social issues. A multi-sectoral economy-energy-environment model has been developed to perform a prospective analysis of the changes in the economic structure and the energy system, as well as to assess the corresponding environmental impacts, providing decision support in policy making. This model is a multi-objective linear programming model that allows for the explicit consideration of distinct axes of evaluation, generally conflicting and non-commensurate, of the merit of distinct policies. The policy recommendations obtained are subject to the inherent uncertainty associated with the model coefficients and, therefore, they may not be robust in face of changes of the input data. The specification of less energy or carbon-intensive technologies is done by considering pollutant/energy coefficients defined as intervals. This analysis is crucial for understanding the role of technology in carbon mitigation efforts and other energy system planning settings, allowing to explore the effects of distinct policies on the total system costs, the fuel and technology mix, and the levels of greenhouse gases and other emissions.     

Novel 120‐Hz TFT‐LCD motion‐blur‐reduction technology with integrated motion‐compensated frame‐interpolation timing controller

Abstract— Samsung has developed a high‐resolution full‐HD (1920 × 1080) 120‐Hz LCD‐TV panel using a novel pixel structure and a motion‐compensated frame‐interpolation (McFi) single‐chip solution. Our latest work includes launch of a 70‐in. full‐HD panel, the world's largest LCD TV in mass production, with a 120‐Hz frame rate. A serious problem involving the charging time margin has been completely overcome through the use of a new alternative 1G‐2D pixel structure and a new driving scheme. Compared with conventional dot‐inversion driving, our new dot‐inversion method, which is a spatial averaging technique, can save power because the column drivers are operated using vertical inversion driving. In addition, McFi, which merges individual ME/MC and timing‐controller (TCON) ICs and memories, has been developed and applied in a mass‐production product for the first time ever. The McFi solution provides 120‐Hz driving with the lowest possible system cost. Motion‐picture response time (MPRT) has been reduced from 1 5 to 8 msec. Moreover, for the case of 24‐Hz film source mode, motion judder has been completely eliminated. As a result, a lineup consisting of 40‐, 46‐, 52‐, 70‐, and 82‐in. LCD‐TV panels with high quality and manufacturability has been made possible.     

3G移动期货行情系统的设计与实现

如今,越来越多的人开始进入期货和证券市场。在期货市场中,一笔投资的成败,往往取决于信息和交易的及时与否。而能够及时获取最新的行情信息,随时随地的进行交易则成为了最为重要也是最为迫切的需求。除了几种传统的交易方式（交易大厅交易、电话委托交易、网上交易等）以外,飞速发展的无线通信网络,为我们带来了一个新的交易平台,即基于移动设备（手机、PDA等）的期货行情交易平台,使“移动期货交易”,即运用手机随时随地查看期货行情、信息、进行期货交易变为可能,且接收信息的即时性和全面性比起其它几种交易方式来说毫不逊色。运用手机进行期货交易,大大方便了期货投资者不受空间、时间限制,随时随地关注期货市场动向。移动期货交易系统是期货交易继因特网电子交易后又一次新的革命。因此,对期货移动交易平台的研究具有很重要的实用意义。
