Variations in the efficiency of a mathematical programming solver according to the order of the constraints in the model
mixed integer linear mathematical programming response time variability problem combinatorial optimization
2009/8/25
It is well-known that the efficiency of mixed integer linear mathematical programming depends on the model (formulation) used. With the same mathematical programming solver, a given problem can be sol...

We investigate static and dynamic routing approaches in overlay IP/GMPLS over optical networks.Dynamic operation for full-wavelength services benefits from physical-layer impairment aware routing wher...
考虑时域硬约束的车辆主动悬架H∞控制（H∞ Control of Active Suspensions with Time-domain Hard Constraints）
车辆 主动悬架 时域硬约束
2009/5/22
提出了考虑时域硬约束条件的车辆主动悬架H∞输出反馈控制器设计方法。基于线性矩阵不等式处理方法，提出并证明了该控制器存在的充分条件。以提高车辆乘坐舒适性为目标，取车身垂直加速度响应为控制输出向量，悬架动挠度、车轮动静载荷比响应和所需控制力为约束输出向量，基于1/4车辆模型进行了主动悬架设计。仿真结果表明，即使车辆模型参数存在一定程度的不确定性，提出的控制策略在提高车辆乘坐舒适性的同时，能很好地兼顾车...

DPS azimuth thrusters
2009/3/27
In a ship DPS equipped with azimuth thrusters, desired forces and moment are realized by means of thrust allocation or control allocation (CA) of determining magnitudes of thrusts and directions of th...
Locality Preserving Constraints for Super Resolution with Neighbor Embedding
Locality Preserving Constraints Super Resolution Neighbor Embedding
2010/12/20
In this paper, we revisit the manifold assumption which has been widely adopted in the learning-based image superresolution. The assumption states that point-pairs from the
high-resolution manifold s...
MULTI IMAGE MATCHING OF STRAIGHT LINES WITH GEOMETRIC CONSTRAINTS
Matching, Straight Lines Correlation Plane Intersection
2015/11/16
Automatic multi image matching of linear features still remains to be a problem in both the photogrammetric and computer vision
communities. Changes in the illumination conditions, camera position, ...
Experimental Analysis of 100Gb/s Coherent PDM-QPSK Long-Haul Transmission under Constraints of Typical Terrestrial Networks
Coherent PDM-QPSK Long-Haul Transmission Constraints Typical Terrestrial Networks
2015/8/3
Coherent transmission systems using PDM-QPSK format are found particularly robust to the constraints of all-erbium amplifiers based, transparent terrestrial networks when operating at 100Gb/s channel ...

A Robust Text Segmentation Approach in Complex Background Based on Multiple Constraints
Text Segmentation Approach Complex Background Multiple Constraints
2010/12/15
In this paper we propose a robust text segmentation method in complex background. The proposed method first utilizes the K-means algorithm to decompose a detected text block into different binary imag...
The aim is to facilitate the application of user defined constraints to the genetic clustering algorithm. This is achieved by presenting a general penalty function. The penalty function is defined as ...
