In this paper, we propose a theoretical entanglement concentration protocol for unknown triparticle W class states, and then the physical implementation of this proposal has also been presented in cavity QED. The general protocol is mainly based on the appropriate Bell state measurements. In the...

In this paper a novel scheme is proposed where with the help of Victor (a state preparer) an unknown EPR pair is copied in a certain probability so that three parties of communication can obtain the EPR state, respectively. The first stage of this scheme is to teleport an unknown EPR state to...

Energy efficiency in industrial boiler steam systems can be very low due to old technologies, improper design and non-optimal operation of the steam systems. Solutions include efficiency assessments and investments in steam system optimizations, education and training for operators of the...

This paper first describes the state-of-the-art of compressed natural gas (CNG) technologies and evaluates the market prospects for CNG vehicles in Beijing. An analysis of the natural gas resource supply for fleet vehicles follows. The costs and benefits of establishing natural gas filling...

In the last quarter of the 20th century, many power companies used the integrated resource planning (IRP) approach in power expansion planning. Today, very few power companies use this approach because of the split between the power generation and distribution activities. It seems that, in some...

Let Xt be a continuous local martingale satisfying X0=0 and K1q(t)[less-than-or-equals, slant]<X>t[less-than-or-equals, slant]K2q(t) a.s. for a nondecreasing function q with constants K1 and K2. Define for a Borel function and Mt*=sup0[less-than-or-equals, slant]s[less-than-or-equals, slant]t Ms....</x>

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...

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,...
