Focusing on the problem of state estimation in the presence of sensor faults and out-of-sequence measurement(ooSm) observations synchronously, we derive a formulation of Linear minimum mean squared error(LmmSE) filter with the arbitrary time delay of ooSm, the generalization of the present work lies in simultaneous treatment of correlated faults together with ooSms that arrive at an arbitrary delay in a linear-optimal manner. the approach is demonstrated in a numerical comparison.

over the centuries,the regeneration field has been puzzled by the dual response of the central nervous system(CNS-brain,spinal cord,cranial nervesⅠandⅡ)and the peripheral nervous system(PNS that refers to all the nerves that innervate muscles,skin,organs,bones among others).Even Ramon y Cajal had noticed that an injury to the PNS often leads to axon regrowth,in contrast to the CNS.

multiple sclerosis(mS)is the most common chronic disease of the central nervous system(CNS)in young adults and represents the first cause of severe handicap,originally non-traumatic(oh et al.,2018).mS is chara cterized by the infiltration of auto reactive lymphocytes specific to myelin through the blood-brain barrier,which results in the appearance of inflammatory demyelinating lesions caused by the death of the central nervous system myelinating cells,oligodendrocytes(oh et al.,2018).there is a prevalence sexual with a ratio of three times more affected women than men.

this paper deals with an experimental, theoretical and numerical study of a turbulent flow with separated boundary layers between a rotor and a stator. the system is not subjected to any superimposed radial flow. the periphery of the cavity is opened to the atmosphere so that the solid body rotation for infinite discs is not always observed. Emphasis was placed on develop- ment of an asymptotic approach and a step-by-step method to compute the radial distribution of the core swirl ratio and the static pressure on the stator side. the theory also includes the radial and axial velocities in the core region. the numerical simulation has been conducted with the commercial CFD code Fluent 6.1. the k- SSt turbulence model is used, with the assumption of 2D-axisymmetric and steady flow. CFD validations have been performed by comparison of the numerical results with the corresponding theoretical results. Numerical and experimental results are in good agreement with analytical solutions.
