فرایند دریافت E- Mark
با گسترش روزافزون صنعت حمل‌و‌نقل درجهان و ارتقای استانداردها، تدوین و اجرای استانداردهای بین‌المللی، یک امر ضروری به‌نظر می‌رسد. E- Mark یک مجموعه قانون‌های هماهنگ بین‌المللی برای خودرو و قطعه‌های آن است که تمامی تولیدکنندگان وسیله‌های نقیله و قطعه‌ها ملزم به رعایت آن هستند. تولیدکنندگان تایر نیز از این امر مستثنی نیستند و باید برای تایرهای خود این مجوز را دریافت کنند. در این مقاله روش دریافت E...
متن کاملOn the Mark and Markaracter Tables of Finite Groups
Let G be a finite group and C(G) be the family of representative conjugacy classes of subgroups of G. The matrix whose H,K-entry is the number of fixed points of the set G/K under the action of H is called the table of marks of G where H,K run through all elements in C(G). Shinsaku Fujita for the first time introduced the term “markaracter” to discuss marks for permutation representati...
متن کاملThe Effect of Damping and Stiffness of Bearing on the Natural Frequencies of Rotor-bearing System
In this paper, the effectiveness of stiffness and damping of bearing is investigated on the natural frequencies of the rotor-bearing system. The rotor-bearing system consists of a shaft, two bearings and a disk between two bearings. Parallel spring-damper in horizental and vertical directions is considered for modeling the stiffness and damping of bearings. The gyroscopic effect is also conside...
متن کاملThe Interrogation Mark
Mark, a lad of eleven summers, was referred to the Psychological Clinic because of failure to pass a grade and for unsatisfactory school conduct. His social history revealed that he was the youngest of a motherless Jewish family of four. The balance of the family comprised three sisters and an orthodox father. His medical history was negative; conditions at birth and subsequent babyhood normal....
متن کاملThe MARK III Collaboration
Absolute branching fractions for the 013 and D/4 decays D++I?‘e+v, , D++K’p+v,, D++K*‘e+v, , and D’+K*-e+v, are determined using completely reconstructed D D events at the y(3770). Reconstructed D’+K-e+v, decays are used to determine the pole mass of the f+($‘) form factor. Resonant K* production dominates the process D+Kxev, the K” polarization is measured. Limits on several Cabibbo suppressed...
