A new method for increasing LDR in deep drawing is application of anti-lock braking system (ABS) on blank holder. In this method, instead of applying a constant force on blank and control the metal flow, the ABS system holds and releases the blank several times (20 to 50 times) which results increasing LDR. This study investigates the effect of different parameters of ABS on improving the condi...

Classes of‎ ‎Abaffy-Broyden-Spedicato (ABS) methods have been introduced for‎ ‎solving linear systems of equations‎. ‎The algorithms are powerful methods for developing matrix‎ ‎factorizations and many fundamental numerical linear algebra processes‎. ‎Here‎, ‎we show how to apply the ABS algorithms to devise algorithms to compute the WZ and ZW‎ ‎factorizations of a nonsingular matrix as well as...

a new method was used to prepare abs/pa6 blends by in situ polymerization and compatibilization method. in this process, ε-caprolactam monomer was polymerized in presence of abs via activated anionic polymerization to produce pa6. the main ingredients of the reaction mixture included: monomer ()ε-caprolactam), catalyst na-caprolactamate), microactivator hdi)( and macro-activator sma)(. then, in...

We present a model and propose an approach to compute an approximate solution of Fully Fuzzy Linear System (FFLS) of equations in which all the components of the coefficient matrix are either nonnegative or nonpositive. First, in discussing an FFLS with a nonnegative coefficient matrix, we consider an equivalent FFLS by using an appropriate permutation to simplify fuzzy multiplications. To solv...

The main aim of this paper intends to discuss the solution of fuzzy Sylvester matrix equation  

background: hydatid cysts are encountered frequently in regions endemic with livestock. the basic treatment for a hydatid cyst is total surgical removal of the cyst and its inner contents. hypertonic nacl or diluted betadine solution are used as germicidal agents for most hydatid surgeries. however, the germicidal efficacy of the ankaferd blood stopper® (abs) has not been investigated. thus, we...
