Abstract This study presents a detailed analysis of the lateral forces generated as result vertically applied loads to recycled plastic drainage kerbs. These kerbs are relatively new addition road infrastructure projects. When concrete is used form kerbs, its deformation minimum when stressed under heavy axle loads. Although more environmentally friendly construction product, they less stiff th...

This paper describes ongoing work into a portable mobility aid, worn by the visually impaired. The system uses stereo vision and sonar sensors for obstacle avoidance and recognition of kerbs. Because the device is carried, the user is given freedom of movement over kerbs, stairs and rough ground, not traversable with a wheeled aid. Motion of the sensor due to the walking action is measured usin...

A key component of a technological aid for the partially sighted (TAPS) is a system to detect kerbs and steps. In this paper, a vision-based kerb detection system is described which uses the Hough Transform to find clusters of parallel lines in the image as evidence for a kerb. This is combined with a stereo vision-based obstacle detection algorithm. Experiments show that kerb regions are ident...

Partial sightedness is a sensory disability which can to some extent be alleviated by artificial aids. Many of the sensory methods used in robotics can be applied in attempts to recapture some of the sensory information a partially sighted person has lost. This paper describes a device which uses sonar and stereo vision sensors for this task. The device is portable, and is worn by the user, giv...

The manual handling of concrete highway kerbs remains commonplace in the construction industry despite obvious risks to operatives. This study was undertaken to find out why kerb installation still includes manual handling, to identify the alternatives that exist and to consider how the organisation of the work affects exposure to risk. Focus groups were held with industry professionals to disc...

BACKGROUND Carbohydrate antigen 15-3 (CA15-3), Kerbs von den Lungen (KL-6) and breast cancer antigen 225 (BCA225) are widely used tumor markers for breast and lung cancer respectively. PATIENTS AND METHODS We analyzed 460 Japanese volunteers for 99 items on blood examination including 27 serum tumor markers. Correlations between 27 tumor markers and the other items were statistically analyzed...
