An ideal self-healing matrix composite which is capable of being monitored for damage events in the matrix so that they can be healed in a thermal cycle to restore the material’s performance without negatively affecting the properties is discussed. A novel technique employing a solid-state matrix repair system for a thermosetting resin that has been shown to be capable of healing of its pre-fra...

More recently, Beik and Salkuyeh [F. P. A. Beik and D. K. Salkuyeh, On the global Krylov subspace methods for solving general coupled matrix equations, Computers and Mathematics with Applications, 62 (2011) 4605–4613] have presented the Gl-FOM and Gl-GMRES algorithms for solving the general coupled linear matrix equations. In this paper, two new algorithms called weighted Gl-FOM (WGl-FOM) and w...

the matrix functions appear in several applications in engineering and sciences. the computation of these functions almost involved complicated theory. thus, improving the concept theoretically seems unavoidable to obtain some new relations and algorithms for evaluating these functions. the aim of this paper is proposing some new reciprocal for the function of block anti diagonal matrices. more...

Today, digital mobile phones are still rarely applied for accessing and using data services. Due to their broad distribution, mobile phones would offer a very attractive platform for information retrieval in different areas, like, e.g., traffic channels, public transportation, sports, and many others. Unfortunately, there are limitations, which prevent the average customer from widely using the...

Gene expression data have become increasingly important in machine learning and computational biology over the past few years. In field of gene analysis, several matrix factorization-based dimensionality reduction methods been developed. However, such can still be improved terms efficiency reliability. this paper, an innovative approach to feature selection, called Dual Regularized Unsupervised...

This letter investigates the impact of antenna element directivity on compressed sensing (CS)-based direction arrival (DOA) estimation employing uniform circular array (UCA) antenna. In CS-based approach, reconstruction accuracy sparse signals is determined by a matrix, which depends configuration in DOA estimation. our study, we analyze cross-correlation between column vectors matrix and clari...

To solve the degradation of the BER performance of Space-Time Block Code (STBC)/MC-CDMA system when MC-CDMA system has large number of users, we propose Unitary Space-Time Modulation (USTM)/MC-CDMA system. USTM combines STBC and baseband modulation by employing unitary matrix. USTM is designed in order not to receive signals from different transmit antennas simultaneously at the receiver. In th...
