The consistency of estimator under fixed design regression model with NQD errors
In this article, basing on NQD samples, we investigate the fixed design
nonparametric regression model, where the errors are pairwise NQD random
errors, with fixed design points, and an unknown function. Nonparametric
weighted estimator will be introduced and its consistency is studied. As
special case, the consistency result for weighted kernel estimators of the
model is obtained. This extends the earlier work on independent random and
dependent random errors to NQD case
A consistent description of kinetic equation with triangle anomaly
We provide a consistent description of the kinetic equation with triangle
anomaly which is compatible with the entropy principle of the second law of
thermodynamics and the charge/energy-momentum conservation equations. In
general an anomalous source term is necessary to ensure that the equations for
the charge and energy-momentum conservation are satisfied and that the
correction terms of distribution functions are compatible to these equations.
The constraining equations from the entropy principle are derived for the
anomaly-induced leading order corrections to the particle distribution
functions. The correction terms can be determined for minimum number of unknown
coefficients in one charge and two charge cases by solving the constraining
equations.Comment: RevTex 4, 11 pages; With minor changes: typos are corrected and one

Multi-Objective Ant Colony Algorithm in EPC Risk Control
AbstractAccording to the risks and risk control target in energy performance contracting (EPC), this paper has designed the risk control measure set. On the basis, a risk control model is put forward, including the risk evaluation, risk control cost, risk loss. Then, a multi-objective ant colony algorithm, based on Pareto theory, is used to solve the model. A series of Pareto optimal solutions are got by example. The result shows that the solutions have the better diversity and convergence. At the same time, the model can find the best combination of various risk control measures in EPC, which can provide direct evidence for the company of EPC
High Altitude Steel Roof Truck Crane Installation
In order to solve the problems of crane operating range in blind areas and insufficient weight support of crane for steel structure bubble roof lifting construction, it is a must to design propelling crane on the roof, so that it can move on selected routes, completing the lifting work of steel roofing bubble. Mainly introduce the technical measures and related technical preparation of propelling crane on the roof for steel structure lifting process, to ensure the originality of steel structure during lifting process and safety of construction work,also to guarantee the progress of steel structure lifting work
