This paper introduces a tow stain detection method based on FPGA. To capture moving images through the line scanning CCD in real time and to design algorithms according to the different characteristics on the tow and stains.Then download it to FPGA development board running and debugging. Finally, displayimages on PC through the video conversion module.The experiments show that this design can ...

The Takeoff Weight (TOW) of an aircraft is an important aspect of aircraft performance, and impacts a large number of characteristics, ranging from the trajectory to the fuel burn of the flight. Due to its dependence on factors such as the passenger and cargo load factors as well as operating strategies, the TOW of a particular flight is generally not available to entities outside of the operat...

this paper presents the application of the generalized differential quadrature (gdq) method for the hydrodynamic analysis of circular and noncircular, two lobe and three lobe, journal bearings. gdq is a simple, efficient, high-order numerical technique and it uses the information on all grid points to approach the derivatives of the unknown function. the effectiveness of the solution technique ...

In the last 30 years since their introduction into aerospace applications, composites have become increasingly used, making up as much as 50% of modern aircraft by weight. Considering this fact, it is surprising that most aircraft today are only scratching the surface of the true potential of composite technology with traditional uniaxial fibers. With the introduction of Automated Fiber Placeme...

Increasing evidence shows that complex diseases are caused by both common and rare variants. Recently, several statistical methods for detecting associations of rare variants have been developed, including the test for testing the effect of an optimally weighted combination of variants (TOW) developed by our group in 2012. These methodologies consider phenotype measurement at only one time poin...

Abstract—In this paper, the dynamic characteristics of a threelobe journal bearing lubricated with micropolar fluids are determined by the linear stability theory. Lubricating oil containing additives and contaminants is modelled as micropolar fluid. The modified Reynolds equation is obtained using the micropolar lubrication theory .The finite difference technique has been used to determine the...

BACKGROUND Return to work is an important outcome following traumatic work-related hand injuries. It is unclear how psychosocial factors affect the time to return to work following traumatic work-related hand injury. AIMS To investigate the relationships between hand injury severity, self-perceived health, demographics and time off work (TOW) following traumatic work-related hand injuries and...

The fundamental frictional behaviour of carbon fibre tows relevant to composite fabric forming is explored. Tow-on-tool and tow-on-tow contact are considered. For tow-on-tool contact, an experiment is devised to simultaneously observe the true filament contact length and measure the friction force over a range of normal loads. Filament contact length is not constant, as would be given from an i...

The aim of this study is to see what the influence of tow-bars is in rear-end collisions, hereby looking at the crash pulse. The database from the Swedish insurance company Folksam and some full-scale tests performed by Autoliv [I, 241 give an indication that the tow-bar increases the injury risk. The increased average acceleration correlates to the increased injury risk. First of all a literat...
