H∞ controller for active magnetic bearings (AMBs) with flexible rotor system was designed in this paper. The motion equations of AMBs and flexible rotor system are built based on finite element methods (FEM). Weighting function matrices of H∞ controller for AMBs are studied for both the sensitivity and the complementary sensitivity of H∞ control theory. The simulation shows that the H∞ control ...

this article is arranged based on a research plan which its goals is evaluation of the possibility of applying flexible human resource structure in industrial organizations. in this research, applying conditions of just in time (j.i.t) and flexible manufacturing systems (f.m.s) have brought up as a pioneer flexible movements in industrial units and based on based two phenomenon, the nescessity ...

conclusions temperaments can provide a basis to classify psychiatric disorders. psychiatric disorders can be placed in a spectrum based on temperaments. results four groups of temperaments were identified: high active, high flexible; high active, low flexible; low active, low flexible; and low active, high flexible. when temperament deteriorates personality, non-psychotic, and psychotic psychia...

Current innovative lateral load carrying systems for tall buildings are those in which the lateral drift is limited to an allowable value without considerable influence on economy. This aim is achieved by using special systems capable of using maximum stiffness and strength capacity of individual structural elements. An effective structural solution in this respect is the use of outrigger brace...

objective: this study was conducted to compare the results of fixed versus flexible gnrh antagonist protocols in controlled ovarian stimulation for intra cytoplasmic sperm injection (icsi) in patients with pcos. materials and methods: a randomized clinical trial was performed on 100 pcos women, who were admitted to a tertiary infertility clinic and were candidate for ivf/icsi. they were divided...

Asset utilization is a major mid-term lever to increase shareholder value creation. Since rough-cut planning of capacity (dis-)investments is performed at the long-term level, detailed timing of adjustments remains for the mid-term level. In combination with capacity control measures, capacity adjustment timing can be used to optimize asset utilization. This paper provides a corresponding frame...

A system simulator for performance evaluation of adaptive antennas in UMTS FDD networks has been developed. The simulator is flexible, it uses realistic channel and system assumptions, and for a given scenario provides the maximum network capacity. The antenna types included in the simulator are switched lobe, phased array and adaptive array as well as conventional fixed sector antenna. Analyse...

Median thinkers are able to consider things from different perspectives and integrate information efficiently for situationally appropriate decisions. Previous research has found that high median thinkers tend to adopt a global and flexible processing strategy compared to low median thinkers, but less is known about how one’s processing capacity is related to his/her median thinking style. Proc...
