We present here a combinatorial method for computing cup-i products and Steenrod squares of a simplicial set X. This method is essentially based on the determination of explicit formulae for the component morphisms of a higher diagonal approximation (i.e., a family of morphisms measuring the lack of commutativity of the cup product on the cochain level) in terms of face operators of X. A genera...

This paper proposes a computer aided decision support system for an automated detection of glaucoma in monocular fundus images. Identification of Glaucoma using fundus images involves the measurement of the size, shape of the Optic cup and Neuroretinal rim. Optic Cup detection is a challenging task because of the interweavement of cup with the blood vessels. A new color model technique based on...

This paper describes two complementary methods for computer analysis of the optic disc in glaucoma. The objective of both techniques is to detect and monitor changes in the optic disc through the use of digital image processing techniques that allow user intervention. In the first method, optic disc photographs from successive years are digitized, scaled and registered (aligned) with each other...

This paper documents a 5-year sport psychology consultancy program with the England Women's Cricket Team. The paper describes the method and content of sport psychology service provided and distinguishes between four phases of delivery: introduction and education in mental skills training, competition preparation and thinking, preliminary World Cup preparation, and final World Cup preparation a...

BACKGROUND This biomechanical study examined difference in cement pressures generated by flanged and unflanged acetabular cups in hip arthroplasty. METHOD Using a model acetabulum, cement was inserted and pressurised followed by cup insertion and pressurisation. Pressures were recorded using transducers in the acetabulum. We compared Charnley Ogee (flanged), Exeter contemporary (flanged) and ...

To simplify 24-hour urine collection for epidemiological and clinical examinations, we devised a portable, semiautomatic urine sampling cup with divided partitions. The cup, 6.6 cm in diameter and 14 cm in height, is double-bottomed and has a pipe-shaped scale and a cock leading to the lower compartment. It is so devised that 1/m of the urine volume excreted into the upper compartment each time...
