This special issue of Forest Policy and Economics is based on the papers presented and discussions held at the International Conference on the New Frontiers of Forest Economics, June 26–30, 2012 held at ETH, Zurich, Switzerland. This paper discusses the need of new frontiers of forest economics, provides an overview of the special issue, and presents thoughts about new frontiers. The paper suggests...
Multi-user multi-input and multi-output based on block diagonalization algorithm can eliminate the multi-user interference, but in fact the existence of the non-ideal factors lead to the interference can not be cancelled completely. In this paper we study the performance of the 3GPP long term evolution system based on BD algorithm and propose a low complexity multi-user scheduling scheme to reduce...
Abstract-Single and Multi-layer adaptive eigen based beamforming (EBB) has been proved to be a promising method to achieve the tradeoff between diversity and spatial multiplexing. But the CQI in multi-layer mode is calculated according to the CQI in single-layer mode. Lack of accurate multi-layer CQI will induce performance loss when implementing layer adaptation at eNodeB. In this paper, aiming to...
According to the analysis on character of enterprise's IT service outsourcing risk, a system dynamics approach is put forward to study enterprise's IT service outsourcing risk in this paper. On the basis of analyzing system target and boundary, the model on system dynamics of IT service outsourcing risk is established, which is combined with risk sub-system, risk control policy sub-system and risk...
The basic concept of clustering and its correlating research work is firstly present, a new algorithm based on least clustering cell (LCC) is proposed and analyzed which concerns the advantages and disadvantage of k-means and grid clustering algorithm. This algorithm is efficient in dealing with huge amounts of data and can make paralleled processing, which is proved to be correct, efficient and fast...
