The paper addresses the question how the effector segments are coordinated during handwriting, in particular as a function of the left-to-right progression within words. It studies the phase relations between wrist and finger-joint rotations during a repetitive graphic task (long words consisting of letters 'e'), and it subjects the resulting continuous phase-relation plots to autocorrelation a...

process capability indices (pcis) can be used as an effective tool for measuring product quality and process performance. in classic quality control there are some limitations which prevent a deep and flexible analysis because of the crisp definition of pca‟s parameters. fuzzy set theory can be used to add more flexibility to process capability analyses. in this study, the fuzzy x ba and mrx ba...

usd7 is one of the steel products of isfahan steel company. it is cast in continuous casting moulds and rolled up to a rod of 5 mm diameter. finally, it is wire drawn up to 3 mm and used as welding electrodes. this steel contains 0.05 to 0.09 wt. % carbon. the acceptable limit of the aluminium in this class of steel is less than 0.003 wt%. therefore, it is categorized as rimmed steel. during fo...

in this paper, we focus on the study of shearlet transform which isdened by using the hyperbolic functions. as a result we check an admissibilitycondition such that implies the reconstruction formula. to this end, we will usethe concept of the classical shearlet, which indicates the position and directionof a singularity.

the problem we investigate deals with the optimal assignment of resources to the activities of a stochastic project network. we seek to minimize the expected cost of the project include sum of resource utilization costs and lateness costs. we assume that the work content required by the activities follows an exponential distribution. the decision variables of the model are the allocated resourc...

conclusions: in the present study, applying positive airway pressure methods (cpap or imv) during cpb was associated with better postoperative abg measurements and (a-a) do2. results: the demographic data were similar in between three groups. graft number, pump time and preoperative abgs were not significantly different. postoperative pao2 were significantly higher in the cpap and imv groups an...

anew and effective electrospinning method has been developed for producing aligned polymer nanofibers. the conventional electrospinning technique has been modified to fabricate nanofibers as uniaxially aligned array. the key to the success of this technique is the creation of a rotating jet by using a cylindrical collector in which the needle tip is located at its center. the unique advantage o...
