F EED manufacturers are often forced by circumstances to focus on short-term concerns such as: How many tons were produced this week? How many customers do I have, or how much down time did I have this week? While important, shortterm problems can cause manufacturers to focus on solving problems rather than pursuing the company’s mission. Manufacturers who regularly examine their company’s miss...

In this paper a new method based on fuzzy theory is developed to solve the project scheduling problem under fuzzy environment. Assuming that the duration of activities are trapezoidal fuzzy numbers (TFN), in this method we compute several project characteristics such as earliest times, latest times, and, slack times in term of TFN. In this method, we introduce a new approach which we call modif...

Nowadays Radio Frequency Identification (RFID) systems have appeared in lots of identification and authentication applications. In some sensitive applications, providing secure and confidential communication is very important for end-users. To this aim, different RFID authentication protocols have been proposed, which have tried to provide security and privacy of RFID users. In this paper, we a...

The role of phonological infonnation in English word identification and the activation pattern of phonological and associative dimensions were investigated with a backward-masking paradigm. Mask type (graphemic, homophonic, associative, unrelated word control, and nonletter #-baseline) and target exposure duration were manipulated. Graphemic and homophonic but not associative masks influenced t...

Early verbal-memory researchers assumed participants represent memory of a pairs of unrelated items with two independent, separately modifiable, directional associations. However, memory for pairs of unrelated words (A–B) exhibits associative symmetry: a near-perfect correlation between accuracy on forward (A→?) and backward (?←B) cued recall. This was viewed arguing against the independent-ass...
