In conventional DEA, measures are classified as either input or output. However, in some real cases there are variables whose status is not known as input or output before assessment. These variable are known as flexible measures. One of the most important economic dimensions for ensuring the success of a company is the efficiency with which it uses its resources. Therefore, centering on Asses...

this paper reviews the possible effects determined on polymeric food packaging films by the simultaneous application of pressure (p) and temperature (t) in high pressure pasteurization and sterilization treatments of packaged foodstuffs. both theoretical modeling and experimental issues are discussed. in fact reversible and irreversible effects that could occur in single film as well as in mult...

Many space applications require robotic manipulators which have large workspace and are capable of precise motion. Micro-macro manipulators are considered as the best solution to this demand. Such systems consist of a long flexible arm and a short rigid arm. Kinematic redundancy and presence of unactuated flexible degrees of freedom, makes it difficult to control micro-macro manipulators. This ...

tendency to optimization in last decades has resulted in creating multi-product manufacturing systems. production planning in such systems is difficult, because optimal production volume that is calculated must be consistent with limitation of production system. hence, integration has been proposed to decide about these problems concurrently. main problem in integration is how we can relate pro...

a  commercial  ti-nanoxide  was  deposited  on  in-doped  sno2 (ito) polymer  substrates by  tape casting  technique with different thicknesses  (7,  14  and  36μm)  to  be  used  as  photoelectrode  in flexible  dye-sensitized  solar  cells  (dsscs).  ruthenium  dye  was adsorbed on each tio2 film for 24 h. the resulting photoelectrodes were used to form flexible dsscs in combination with elec...
