This paper addresses the three-axis stabilization of a satellite system in the presence of the gravity gradient and orbital eccentricity. Multivariable non-linear dynamics of the satellite system are converted into three well-known non-linear canonical independent models with unknown parameters. The new model is efficient and practical for designers to implement and analyze different control me...

OpenTuner can help users achieve better or more portable performance in their speci c domain through program autotuning. A key challenge for users seeking good autotuning performance in OpenTuner is selecting a search approach appropriate for problem. However, not only are current in-situ learning search approaches not robust enough to handle all search spaces, but there are also too many possi...

The process of empirical autotuning results in the generation of many code variants which are tested, found to be suboptimal, and discarded. By retaining annotated performance profiles of each variant tested over the course of many autotuning runs of the same code across different hardware environments and different input datasets, we can apply machine learning algorithms to generate classifier...

Chemical reaction cycles can regulate molecular self-assembly. Vice versa , self-assembly rates. Here, we show design rules to tune such reciprocal coupling in dissipative

Abstract RNA-based gene control mechanisms pose an elegant and straightforward way to switch on, off, or fine-tune transgene expression without the need for expressing regulatory proteins. A small molecule effector binds directly a ligand-binding aptamer RNA structure thereby modulates of associated target gene. We established genetic switches based on regulation self-cleaving ribozymes polyade...

aim and background: this study reviewed the effectiveness of self-control training on quality of life in patients with multiple sclerosis (ms). to do so, 40 patients with ms were selected through convenient sampling method among the study subjects with multiple sclerosis recorded in ardabil in 2012 (estimation: n = 350). methods and materials: this was a clinical trial designed as pretest postt...
