Remote sensing has changed modern oceanography by proving synoptic periodic data which can be processed. Since the satellite data are usually too much and nonlinear, in most cases, it is difficult to distinguish the patterns from these images. In fact, SOM (Self-Organizing Maps) model is a type of ANN (Artificial Neural Network) that has the ability to distinguish the efficient patterns from th...

Satellite cells are responsible for growth, maintenance and repair of postnatal skeletal muscle. On the search for a specific marker molecule for the identification of satellite cells by light-microscopy, we examined M-cadherin, a Ca-dependent cell adhesion molecule which is present in quiescent as well as activated satellite cells but not in other cell types in skeletal muscle. To determine th...

When a robot arm(s) conducts some tasks on a satellite, the satellite attitude stability is necessary against the robot arm's motion to maintain the communication link and to generate electrical power from the solar panel(s). However the reaction from the robot arm is much stronger than the natural environmental disturbance torque that the traditional satellite attitude control system cares. Na...

Satellite image classification process involves grouping the image pixel values into meaningful categories. Several satellite image classification methods and techniques are available. Satellite image classification methods can be broadly classified into three categories 1) automatic 2) manual and 3) hybrid. All three methods have their own advantages and disadvantages. Majority of the satellit...

We have identified and determined the sequence and organization of a new rat satellite DNA in Rattus rattus, the roof rat. This satellite DNA, which we call R. rattus satellite I', consists of tandem arrays of a 185 base pair (bp) repeat unit that we call a'. a' is 86% homologous to a 185 bp portion of the 370 bp repeat unit of the previously described rat satellite [Pech et al. (1979) Nucleic ...

Different from terrestrial networks, satellite network topology is time-varying. Moreover, satellite networks communication resources are scare and expensive. So it is important to research on the fault management for satellite networks to insure it work safely and smoothly. However, the traditional fault management method for terrestrial networks is difficult to use for satellite networks. In ...
