An architecture for object-oriented intelligent control of power systems in space [PDF]

A control system for autonomous distribution and control of electrical power during space missions is being developed. This system should free the astronauts from localizing faults and reconfiguring loads if problems with the power distribution and ...

Square-lattice magnetism of diaboleite Pb2Cu(OH)4Cl2

, 2013
We report on the quasi-two-dimensional magnetism of the natural mineral diaboleite Pb2Cu(OH)4Cl2 with a tetragonal crystal structure, which is closely related to that of the frustrated spin-1/2 magnet PbVO3.

Neuroprotective effects of carnitinoid compounds in rodent cellular and in vivo models of mitochondrial complex I dysfunction [PDF]

, 2019
Rotenone-mediated mitochondrial complex I inhibition was used to model Parkinson’s disease-like syndrome in Lewis rats. Tyrosine hydroxylase immunolabeling demonstrated a decrease in the number of dopaminergic neurons as well as aberrant morphology in ...

Direct Evidence of Mg Incorporation Pathway in Vapor-Liquid-Solid Grown p-type Nonpolar GaN Nanowires

, 2015
Doping of III-nitride based compound semiconductor nanowires is still a challenging issue to have a control over the dopant distribution in precise locations of the nanowire optoelectronic devices.

Inverse Simulation as a Tool for Fault Detection and Isolation in Planetary Rovers [PDF]

, 2017
With manned expeditions to planetary bodies beyond our own and the Moon currently intractable, the onus falls upon robotic systems to explore and analyse extraterrestrial environments such as Mars. These systems typically take the form of wheeled rovers,

Martian canyons and African rifts: Structural comparisons and implications [PDF]

The resistant parts of the canyon walls of the Martian rift complex Valled Marineris were used to infer an earlier, less eroded reconstruction of the major roughs. The individual canyons were then compared with individual rifts of East Africa.

Reduction of lattice thermal conductivity from planar faults in the layered Zintl compound SrZnSb_2 [PDF]

, 2011
The layered Zintl compound SrZnSb_2 is investigated using transmission electron microscopy (TEM) to understand the low lattice thermal conductivity. The material displays out-of-phase boundaries with a spacing from 100 down to 2 nm.

Diagnostic tolerance for missing sensor data [PDF]

For practical automated diagnostic systems to continue functioning after failure, they must not only be able to diagnose sensor failures but also be able to tolerate the absence of data from the faulty sensors.

Semi-Supervised Informer for the Compound Fault Diagnosis of Industrial Robots

Sensors
The increasing deployment of industrial robots in manufacturing requires accurate fault diagnosis. Online monitoring data typically consist of a large volume of unlabeled data and a small quantity of labeled data. Conventional intelligent diagnosis methods heavily rely on supervised learning with abundant labeled data. To address this issue, this paper
