In this paper, quantum efficiency (QE) measurements performed on type-II InAs/GaSb superlattice (T2SL) photodiodes operating in the mid-wavelength infrared domain, are reported. Several comparisons were made in order to determine the SL structure showing optimum radiometric performances : same InAs-rich SL structure with different active zone thicknesses (from 0.5μm to 4μm) and different active...

The article considers changes in natural patterns of moisture transport parameters under waterlogging and lowering groundwater table, conditions filtration-anisotropic strata. nature anisotropy characteristic river sediments (alluvial, pluvial, deltaic their combinations) is the most widespread surface zone earth’s crust. Impact factors: external artificial, process drainage, affect both positi...

NTRODUCTION The articular cartilage has a matrix structure of three layers superficial zone, middle zone and deep zone, which are divided by the different orientations of collagens. Recent publications have shown fractional anisotropy (FA) can reflect the orientation of the collagen fibers using diffusion tensor imaging (DTI) in MRI [1-3]. However, the FA contrasts were low especially between t...

Abstract. Synchronization of fractional order chaotic dynamical systems is receiving increasing attention in recent decades. In this article, a fractionalorder financial system is proposed and we utilize active control technique to synchronize this fractional order chaotic dynamical system based on the stability theory of fractional order systems. It is observed that synchronization is faster a...

INTRODUCTION Focal cortical dysplasias (FCD) are cortical malformations and, although they display typical characteristics in conventional magnetic resonance imaging (MRI), the precise determination of the epileptogenic zone remains a controversial issue. The less favourable progress during the post-operative period with respect to other symptomatic epilepsies could be explained by the existenc...

An offshore zone of faulting approximately 10 km from the southern California coast connects the seismically active strike-slip Newport–Inglewood fault zone in the Los Angeles metropolitan region with the active Rose Canyon fault zone in the San Diego area. Relatively little seismicity has been recorded along the offshore Newport–Inglewood Rose Canyon fault zone, although it has long been suspe...

The synchronization between fractional-order hyperchaotic systems and integer-order hyperchaotic systems via sliding mode controller is investigated. By designing an active sliding mode controller and choosing proper control parameters, the drive and response systems are synchronized. Synchronization between the fractional-order Chen chaotic system and the integer-order Chen chaotic system and ...
