It has been reported in previous work that students’ online tutoring data collected from intelligent tutoring systems can be used to build models to predict actual state test scores. In this paper, we replicated a previous study to model students’ math proficiency by taking into consideration students’ response data during the tutoring session and their help-seeking behavior. To extend our prev...

The performance of federated learning (FL) over wireless networks depend on the reliability client-server connectivity and clients' local computation capabilities. In this article we investigate problem client scheduling resource block (RB) allocation to enhance model training using FL, a pre-defined duration under imperfect channel state information (CSI) limited computing resources. First, an...

I present a full leading–order calculation of F2(x,Q ) and FL(x,Q ), including contributions not only from leading order in αs, but also from the leading power of αs for each order in ln(1/x). The calculation is ordered according to the inputs and evolution of the structure functions, and the perturbative form of the inputs is determined. I compare the results of fits to data to those using con...

The paper presents the potential of fuzzy logic (FL-I) and neural network techniques (ANN-I) for predicting the compressive strength, for SCC mixtures. Six input parameters that is contents of cement, sand, coarse aggregate, fly ash, superplasticizer percentage and water-to-binder ratio and an output parameter i.e. 28day compressive strength for ANN-I and FL-I are used for modeling. The fuzzy l...

abstract norton’s (1995) investment hypothesis in l2 learning that l2 learners who cherish and foresee a richer personality for themselves in their l2 context would thrive more diligently and consequently would both enrich their personality and achieve a higher proficiency in their new language was investigated in this study in the community of iranian efl students. the integration and mutual r...

the present study was an attempt to investigate the acquisition of negationproperties by persian monolingual and kurdish-persian bilingual learners of englishacross different levels of language proficiency and within a generative framework.generative models are generally concerned with issues such as universal grammar(ug), language transfer, and morphological variability in nonprimary languaged...

this study was an attempt to find out to what extent efl learners at different levels of language proficiency experience inner speech as mental rehearsal and to identify some of the characteristics and functions of their inner speech. for this purpose, one hundred seventy-four iranian female students majoring in english translation at islamic azad university, tehran central branch, took part in...

We present calculations of structure functions using a renormalization scheme consistent expansion which is leading order in both ln(1/x) and αs(Q ). There is no factorization scheme dependence, and the “physical anomalous dimensions” of Catani naturally appear. A relationship between the small x forms of the inputs F2(x,Q 2 0) and FL(x,Q 2 0) is predicted. Analysis of a very wide range of data...

background: abdominal circumference (ac), biparietal diameters (bpd) and femoral length (fl) are now the main parameters used to obtain estimated fetal weight (efw). although the role of soft tissue parameters in determining fetal weight was proved but clinical attention to mid-thigh soft tissue thickness (stt) is limited. objective: to find the impression of stt on birth weight (bw) and repres...

Characteristic secondary metabolites, including flavonoids, theanine and caffeine, are important components of Camellia sinensis, and their biosynthesis has attracted widespread interest. Previous studies on the biosynthesis of these major secondary metabolites using next-generation sequencing technologies limited the accurately prediction of full-length (FL) splice isoforms. Herein, we applied...
