In this paper, a propeller optimization model is presented to find the optimum geometry and gearbox ratio for different angles of shaft while minimizing amount fuel consumed at given speed complying with proposed constraints' limitations. The developed couples several simulation software where application programming interface (API) facilitates data processing achieve design based on procedures...

The purpose of this study was to examine the "recoil" effect of the ice hockey stick shaft during a stationary slap shot. Nine male adult subjects (four elite and five recreational) were tested. Their performances were evaluated by simultaneously recording stick movement and internal bending from high-speed digital video (1,000 Hz) and puck acceleration from a triaxial accelerometer positioned ...

A total of 125 consecutive hip fracture patients were investigated regarding hip geometry. There were 33 men of mean age 76 +/- 10 years, and 92 women of mean age 78 +/- 9 years. Patients with previous hip surgery were excluded. Hip geometry (hip-axis length, width of collum femoris, and femoral shaft and neck-shaft angle) were registered on both plain radiographs and DEXA scans performed withi...

Abstract Experimental results of a transonic compressor blade pressure loadings and shaft torque measurements are presented in this paper. Data were acquired for the cascade middle being set to number incidence angle offsets simulate phases flutter oscillatory motion. This paper should be viewed as progress report on ongoing larger research effort flow regimes.

We present the outcome of non-operative management of fractures of the shaft of the femur in children. Thirty children with non-operatively managed unilateral fractures of the shaft of the femur were studied. The mean age was 6.5 years (range: 1.2 to 12). Axial, angular and rotational malunion were assessed clinically and radiologically by plain films and computed tomography (CT). All children ...

OBJECTIVE To describe the mechanical rationale and clinical application of prototype right-angle reduction forceps. METHODS A pair of prototype right-angle reduction forceps was designed and manufactured specifically to improve the consistency and ease of fracture reduction. It was used to reduce mandible fractures of the mandible body, parasymphysis, and symphysis in 4 patients. The fracture...

in this paper the design, implementation, and evaluation of an experimental-scale potato yield monitoring system is presented. the main objective of this research was to develop a method for accurate mapping of potato yield. at the first stage an instantaneous yield monitoring system was mounted on a potato harvesting machine. this system consisted of a weighing tray, two load cells, a shaft rp...

[Purpose] The purpose of this study was to identify the optimum setting position grip, by investigating effect difference in direction angle between grip and shaft a T-cane on dynamic stability wrist joint, order develop that does not cause pain joint. [Participants Methods] participants were 18 males 2 females. We assumed that, during use, tenodesis function would functionally stabilize change...

abstract   background: fractures of the tibia are important for their commonness and controversy in their management. both conservative and surgical techniques have been introduced in an effort to speed time to :::::union::::: while minimizing the occurrence of complications. standard treatment for low-energy tibial shaft fractures includes closed reduction and cast immobilization. the purpose ...

OBJECTIVE To describe a new scheme of skin cover in epispadias repair to improve the aesthetic results and minimize complications. PATIENTS AND METHODS In the last 4 years, 7 male continent epispadias (aged 2-5 years) undergoing Cantwell-Ransley repair received a new technique of skin cover. After a U-shaped incision along the margin of urethral plate, a transverse incision beginning at the m...
