Electromagnetic docking technology can realize the flexible and safe separation of spacecraft, presents broad application prospects. However, an electromagnetic force with nonlinearity uncertainty properties increases difficulties control. In this work, magnetic dipole far-field model a single coil has been established by simplifying device. Afterward, torque models were obtained during space d...

A fast intra/inter mode decision method using a risk-minimization criterion is proposed to reduce the encoder complexity of the H.264 encoder in this work. The current H.264 reference codes employ exhaustive search to find the best mode that optimizes the rate-distortion performance among all possible intra/inter predictive modes. To develop a fast binary mode decision scheme (i.e. either the i...

in this paper we consider the non-preemptive variant of a multi-mode resource constrained project scheduling problem (mrcpsp) with mode identity, in which a set of project activities is partitioned into disjoint subsets while all activities forming one subset have to be processed in the same mode. we present a depth-first branch and bound algorithm for the resource constrained project schedulin...

An increasingly common approach being taken by taxonomists to define the relationships between taxa in alternative hierarchical classifications is to use a set-based notation which states relationship between two taxa from alternative classifications. Textual recording of these relationships is cumbersome and difficult for taxonomists to manage. While text based GUI tools are beginning to appea...

In this article, we study the coupled mode space approach to nonequilibrium Green’s function NEGF simulation. When the lateral confinement of nanoscale devices changes abruptly and the correlation functions arising from coupled mode effects are improperly evaluated in the current and charge density calculations, it becomes difficult to solve nonequilibrium Green’s function equations self-consis...

Snake robots are mostly designed based on single mode locomotion. However, single mode gait most likely could not work effectively when the robot is subject to an unstructured working environment with different measures of terrain complexity. As a solution, mixed mode locomotion is proposed in this paper by synchronizing two types of gaits known as serpentine and wriggler gaits used for non-con...
