Optical phased array (OPA) is a promising beam-steering device for various applications such as light detection and ranging (LiDAR), optical projection, free-space communication switching. However, the previously reported OPAs suffer from either an insufficiently small number of resolvable points, or complicated control requirement due to extremely large phase shifters. This work introduces nov...

conclusions test-retest and correlation analyses have identified non-redundant radiomics features and this feature are prone to errors if they employed as quantitative biomarker for gbm image analysis. however when we use robust and redundant feature, quantitative image radiomics features are informative and prognostic biomarkers for gbm magnetic resonance imaging. results results shows that th...

The quest for high-performance has led to multiand many-core systems. To push the performance of a single core to the limit, simultaneous multithreading (SMT) is used. SMT enables to fetch different instructions from different threads, hiding latencies in other threads. SMT also gives the opportunity to execute redundant threads (redundant multithreading, RMT) and thus to detect faults by compa...

Redundancy allocation problem is one of the most important problem in Reliability area. In this problem the reliability and availability of the systems maximized via allocating redundant components to sub-systems. a systems operates normally in its operational mode but fails in either opened or shorted modes. this paper presents a repairable k_out_of_n systems network model with common cause fa...

G-Frames in Hilbert spaces are a redundant set of operators which yield a representation for each vector in the space. In this paper we investigate the connection between g-frames, g-orthonormal bases and g-Riesz bases. We show that a family of bounded operators is a g-Bessel sequences if and only if the Gram matrix associated to its denes a bounded operator.
