A simultaneous estimation of two convective boundary conditions problem of a two-dimensional rectangular fin is proposed by numerical approach. The aim is to estimate the evolution of the distributions of the unknown heat transfer coefficients from the transient temperature histories taken with several sensors inside a two-dimensional fin. The estimation algorithm of this inverse heat conduction problem is based on the iterative regularization method and on the conjugate gradient method. An optimal choice of the vector of the descent parameters is used in this study and shows an increase in the convergence rate. The effects of some parameters (sensor number, position, measurement errors) on the inverse solutions are discussed. 相似文献

Word recognition and basic cognitive processes among reading-disabled and normal readers in Arabic 总被引:1,自引:0,他引:1
This study investigated word identification inArabic and basic cognitive processes inreading-disabled (RD) and normal readers of thesame chronological age, and in younger normalreaders at the same reading level. The studyfocused on the word identification processes ofphonological decoding and orthographicprocessing and the cognitive processes ofsyntactic and morphological awareness, workingmemory, and visual processing. RD children werecompared with normal readers on a battery oftests developed in Arabic on the basis of thoseavailable in English and Hebrew. The presentresults revealed deficiencies among the RD childrenin phonological decoding, in contrast torelative strengths in orthographic processing. These data were consistent with English-languagefindings. The analysis of basiccognitive processes indicated significantdeficiencies in morphology, working memory, andsyntactic and visual processing, with the mostsevere deficiencies observed for phonologicalawareness. The results are discussed in lightof international RD findings and the nature ofArabic orthography. 相似文献

We introduce a new modified Mason-Coates graph (denoted by RMC-graph) specifically for discrete-time network analysis. The previously developed Mason-Coates graph (MC-graph), used for continuous-time networks, is summarized to simplify our presentation. The concise RMC-graph interpretation of a given digital network example is included. 相似文献

Drawing on interviews with Muslim parents, students, and teachers in a Midwestern city, as well as one of the author's (Sabry's) own experiences as a member in the local Muslim community, this paper documents and describes the challenges faced by Muslim youth in U.S. schools. Grounded in the theoretical framework of cultural mismatch, the paper presents key themes of the interviews with regards to the areas of curriculum, instruction, and home-school relations. Based on these findings, and using Banks' Multicultural Education Dimensions, a proactive model of cooperation between the families of Muslim students and the public school system is proposed. The paper concludes by urging other scholars to investigate the schooling of Muslim students in the U.S. and encouraging members of the Muslim community to share their U.S. schooling experiences. 相似文献

Implement VLANs essentially creating smaller broadcast domains at layer 2, means that broadcasts sent out from a node in one VLAN won t be forwarded to ports configured to belong to a different VLAN. In this paper, we assigning users to VLAN groups on a switch, this help to gain the flexibility to add only the users you want into that broadcast domain regardless of their physical location. This setup can also work to block broadcast storms caused by a faulty network interface card (NIC) as well as prevent an intermediate device from propagating broadcast storms throughout the entire internetwork. 相似文献

The educational policy in Morocco is aimed at promoting the wide use of Information and Communication Technologies in Education and the adoption of interactive and autonomous digital resources for distance teaching and self-learning. The objective of this research is to evaluate the suitability of the existing digital educational resources for distance learning purposes by analysing their interactivity and autonomy. The study of the contents of 190 existing products for teaching and learning Life and Earth Sciences in high schools has revealed the existence of weaknesses related to interactivity and autonomy. The results have been used to set down guidelines for designers of future interactive and autonomous digital educational resources for distance learning use. 相似文献
