The machining precision in the scroll compressor with the compliant crank mechanism is not required so high as that with the fixed throw crank, but the sealing performance is better than the later's, therefore the scroll compressor with the compliant crank mechanism operates at higher efficiency. In this study, the characters of the compliant crank mechanism are discussed, while the Oldham coup...

in this paper, the methodology of aircraft air distribution system has been analyzed theoretically and experimentally. to achieve that, ducting pressure loss and air flow throw gaspers calculations has been done for cabin ducts in according to exact location of individual air distribution system in the cabin. the length of gasper air flow was compared with the distance between gasper outlet and...

the purpose of this study was to investigate the effects of body mass index on fundamental motor skills performance in 7-8-year-old boys in hamedan. forthis purpose, 72 elementary students were selected via cluster randomization from the elementary schools of hamedan and divided into three groups: fat, normal, and thin according to percentile diagram. then, tgmd-2 was performed by children and ...

The Android app developed in this work enables the user to take aerial photographs by throwing the smartphone in the air. This involved overcoming inherent limitations of the underlying system, such as camera lag and sensor saturation. A motion detection algorithm is proposed which reliably detects the stages of a vertical throw and copes with the system’s limitation. Experiments show that the ...

Objectives: Upper limb explosive power is an important motor quality for sporting performance and indicates use of anaerobic energy systems. The Wingate Anaerobic Test (WAnT) has been considered to be a valid reliable tool the assessment functional elite athletes. However, it expensive lab based test requires skilled manpower. seated medicine ball throw (SMBT) inexpensive, easy assess since equ...

[Purpose] To clarify the motion-plane dependency of the range of dart throw motion and the effects of tendon action due to long finger flexors and extensors during the motion. [Subjects and Methods] Forty healthy subjects attended the experiment, and the active range of wrist motion in seven motion planes was measured with an originally designed apparatus. [Results] The reliability of the measu...

The catch/throw mechanism in Common Lisp gives a simple control structure for non-local exits. Nakano[7, 9] and Sato[13] proposed intuitionistic calculi with inference rules which give logical interpretations of the catch/throw-constructs. Although the calculi are theoretically well-founded, we cannot use the catch/throw mechanism for handling run-time errors in a meaningful way, because of the...

the aim of this research work was to investigate on the ball filling estimation of miduk semi-autogenous (sag) mill via an utilized method. miduk copper concentrator is located in kerman province, iran, and its size reduction stage includes one gyratory crusher which feeds one sag mill (9.75 dia.(m)*3.88 length(m)) following two parallel ball mills (5dia.(m)*7lenght(m)). after sag mill, a tromm...

the purpose of present study was investigation of the effect of attentional focus of novice players’ self-statements in basketball free throw practice on their state anxiety in transfer test with spectators’ presence. therefore, 38 novice females (mean of the age=22 yrs.) who had intermediate trait anxiety were selected randomly by sports competitive anxiety test (scat). the participants were a...
