We investigate the dynamics of quantum discord during the purification process. In the case of Werner states, it is shown that quantum discord is increased after a round of purification protocol. Furthermore, quantum mutual information and classical correlation is also increased during this...

The objective of this paper is to quantify the development of the rural electricity market at county level and below in China. A sectorial energy demand analysis and forecasting model was developed to analyze six Chinese provinces with different economic backgrounds. Historical data for over 20...

The objective of this paper is to identify the most cost-effective areas for Demand Side Management (DSM) in Nepal. On-site interviews were undertaken with power utilities (the Nepal Electricity Authority or NEA and its sub-companies) and various electricity end-users in Nepal to collect data,...

Using the highly detuned interaction between three-level Λ-type atoms and coherent optical fields, we can realize the C-NOT gates from atoms to atoms, optical fields to optical fields, atoms to optical fields and optical fields to atoms. Based on the realization of the C-NOT gates we propose an...

In this paper, we first propose a general entanglement distillation protocol for three-particle W class states, which can concentrate the W′ state (non-maximally entangled W state). The general protocol is mainly based on the unitary transformations on the auxiliary particles and the entangled...

Solar air heaters are becoming more and more popular in space heating and industrial processes due to their cost effectiveness and easy maintenance. However, how to increase thermal efficiency of solar air heaters becomes a major challenge. In this paper, the design of a solar air heater with...

Let Xt be any additive process in . There are two lower indices and an upper index [beta]T for T[set membership, variant](0,[infinity]) such that for any Borel set , if , and dimHX(E)=[beta]TdimHE, where X(E)={Xs:s[set membership, variant]E} for and dimH denotes the Hausdorff dimension. When Xt...

Compressed air systems in a Vietnamese footwear manufacturing enterprise consume about 10% of enterprise's total electric power supply. Energy efficiency of these air compressor systems, either equipped with new and efficient compressors or old and inefficient ones, can only reach between 5% and...
