همواره محدودیت منابع در سازمان ها، مطرح بوده، بنابراین استفاده بهینه از این منابع و ارتقای کارآیی هدف اساسیاست که هر سازمانی به دنبال آن می باشد. دانشگاه ها به عنوان بدنه اصلی آموزش عالی و منبع مهم تامین نیروی انسانی، نقش مهمی در توسعه کشورها دارند. از این رو سنجش جایگاه کارآیی دانشگاه ها و بهبود آن یک هدف مهم به شمار می آید. روش تحلیل پوششی داده ها(dea)، توان رتبه بندی کارآیی را مشروط به عدم ...
on this project we try to calculated power of hydrogen on dycarbonil compound in different ways ; the first way is shoster way , for sain power of hydrogen notice the different power between central conforms on it and main conform that’s didn’t have hydrogen joint . or in other way different of energy between open and close form. second way, is average way? this is for way that studied conf...
We report on studies of the dwell fatigue crack growth (FCG) behavior commercial pure titanium (CP-Ti) TA2 weld joints at 25 °C and 200 °C. Taking into account effects load ratio temperature, impact FCG associated fracture mechanism are clearly demonstrated. Meanwhile, in order to illustrate creep–fatigue interaction, finite element simulations also performed analyze evolution stress strain fie...
Elderly onset Rheumatoid arthritis (EORA) has important clinical distinctions when compared with younger onset RA (YORA). In knee arthritis of elderly patients, infection, crystal-induced arthritis or EORA should be suspected if elevation of CRP in the preoperative examination and turbid joint effusion in their knee joint are found. Furthermore, if joint swelling and effusion remain after perfo...
Patients with trapeziometacarpal joint arthritis stage II or III (according to Dell) and no benefit from non-operative therapy were selected to undergo joint arthroplasty. We performed 32 arthroplasties for first carpometacarpal arthritis in 27 patients using a cementless total trapeziometacarpal joint prosthesis. We undertook a prospective cohort study and evaluated the clinical results of tot...
Read: Chapters 5 and 6 of [CGH]. The first model for a joint probability distribution that we will consider is the undirected graph. We will undirected graphs using two different methods. First, we will show the relationship between undirected graphs and joint probability distributions. Second, we will show the relationship between undirected graphs, and an abstract independence model (called a...
Serving to improve stability and energy efficiency during locomotion, in nature, animals modulate their leg stiffness to adapt to their terrain. Now incorporated into many locomotive robot designs, such compliance control can enable disturbance rejection and improved transition between changing ground conditions. This paper presents a novel design of a variable stiffness leg utilizing a magneto...
