in the processing of carbon/carbon composites using polymer resin as the matrix precursor, it is inevitable that a porous structure was formed after carbonization. as a result, densification by liquid phase impregnation followed by recarbonization is required to obtain a densified composite. consequently, the char formability of resin is an important factor in reducing the number of densificati...

The convex body maximal operator is a natural generalization of the Hardy–Littlewood operator. In this paper we are considering its dyadic version in presence matrix weight. To our surprise it turns out that not bounded. This sharp contrast to Doob's inequality context. At first, show Carleson Embedding Theorem with weight fails. We then deduce unboundedness matrix-weighted

The way for performing multiple sequence alignment is based on the criterion of the maximum scored information content computed from a weight matrix, but it is possible to have two or more alignments to have the same highest score leading to ambiguities in selecting the best alignment. This paper addresses this issue by introducing the concept of joint weight matrix to eliminate the randomness ...

In this paper, a new method is proposed for the production of MWCNTs/PVC (multi-walled carbon nanotubes/ polyvinyl chloride) nanocomposites. In this method, a spray is used to produce layers of carbon nanotubes within a PVC matrix. Various parameters influence the production of the nanocomposite and its mechanical properties. These parameters are studied separately and the effect of each of par...

In this paper, a new soft computing group decision method based on the concept of compromise ratio is introduced for determining decision makers (DMs)' weights through the group decision process under uncertainty. In this method, preferences and judgments of the DMs or experts are expressed by linguistic terms for rating the industrial alternatives among selected criteria as well as the relativ...

In the present study, modelling and vibration analysis of Carbon nanotubes/ fiber/ polymer composite microplates are investigated. The governing equations of the Carbon nanotubes/ fiber/ polymer composite microplates are derived based on first order shear deformation plate theory, rather than other plate theories, due to accuracy and simplicity of polynomial functions. The modified couple stres...

In this study,formulation of sustained-releasingmatrix tablet of bupropion 150 mg, using hydroxypropylmethylcellu lose(HPMC) 4000cps was evaluatedwith the aim of reducing the frequency of daily dose. The level of HPMC4000 ,polyvinylpyrolidone(PVP) and magnesium stearate(Mg St)was varied based on a 2level 3 factor factorial experimental designusing the release rate of the drug from the matrices ...
