K-quantum Nonlinear Jaynes-Cummings Model in Two Trapped Ions
A k-quantum nonlinear Jaynes-Cummings model for two trapped ions interacting
with laser beams resonant to k-th red side-band of center-of-mass mode, far
from Lamb-Dicke regime, has been obtained. The exact analytic solution showed
the existence of quantum collapses and revivals of the occupation of two atoms.Comment: 8 pages, 3 figure
NLO corrections to WWZ and ZZZ production at the ILC
We calculate the full one-loop electroweak corrections to tri-boson
production (ZZZ and WWZ) at the ILC. This is important to understand the
Standard Model (SM) gauge quartic couplings which can be a window on the
mechanism of spontaneous symmetry breaking. We find that even after subtracting
the leading QED corrections, the electroweak corrections can still be large
especially as the energy increases.Comment: 7 pages, proceedings of the 3rd CPP Workshop, September 23-25, 2010,

Scenario-based Economic Dispatch with Uncertain Demand Response
This paper introduces a new computational framework to account for
uncertainties in day-ahead electricity market clearing process in the presence
of demand response providers. A central challenge when dealing with many demand
response providers is the uncertainty of its realization. In this paper, a new
economic dispatch framework that is based on the recent theoretical development
of the scenario approach is introduced. By removing samples from a finite
uncertainty set, this approach improves dispatch performance while guaranteeing
a quantifiable risk level with respect to the probability of violating the
constraints. The theoretical bound on the level of risk is shown to be a
function of the number of scenarios removed. This is appealing to the system
operator for the following reasons: (1) the improvement of performance comes at
the cost of a quantifiable level of violation probability in the constraints;
(2) the violation upper bound does not depend on the probability distribution
assumption of the uncertainty in demand response. Numerical simulations on (1)
3-bus and (2) IEEE 14-bus system (3) IEEE 118-bus system suggest that this
approach could be a promising alternative in future electricity markets with
multiple demand response providers
Constrained low-tubal-rank tensor recovery for hyperspectral images mixed noise removal by bilateral random projections
In this paper, we propose a novel low-tubal-rank tensor recovery model, which
directly constrains the tubal rank prior for effectively removing the mixed
Gaussian and sparse noise in hyperspectral images. The constraints of
tubal-rank and sparsity can govern the solution of the denoised tensor in the
recovery procedure. To solve the constrained low-tubal-rank model, we develop
an iterative algorithm based on bilateral random projections to efficiently
solve the proposed model. The advantage of random projections is that the
approximation of the low-tubal-rank tensor can be obtained quite accurately in
an inexpensive manner. Experimental examples for hyperspectral image denoising
are presented to demonstrate the effectiveness and efficiency of the proposed
method.Comment: Accepted by IGARSS 201
A KPN based Model for Describing and Verifying the Interaction of Web Services
Correct interaction between Web services is essential for successful Web service composition. This paper proposes a Web
Service Interaction Model (IWSN) that aims to ensure correct interaction between Web services, improve the scalability of Web service
composition, solve behavioral compatibility issues in the process of Web service interaction, and promote the application of service
composition technology in related fields. The Kahn Process Network (KPN) supports parallel computing based on data streams and
channels, and the proposed Web Service Interaction Model in this article is based on the KPN. The formal semantics of the IWSN model are
based on process algebra Pi calculus, and the model's properties are discussed. Finally, an application case is used to demonstrate how the
IWSN model can be applied to Web service composition and interaction
