The introduction of carbon-fibre reinforced plastics in load bearing automotive structures provides a great potential to reduce vehicle weight and fuel consumption. A reduction in overall manufacturing cost can be realised through part integration and use of cost-effective materials such as heavy tow carbon fibre. There is a current drive within the automotive industry to develop the technologi...

Biliary drainage of the left liver lobe has been examined in view of the current surgical trends for using the left liver lobe of living parent donor for liver transplantation. For this purpose, on 13 acrylic casts of porto-biliary elements of the liver, variations of pattern and level of merging of segmental ducts into a left lobe (lateral) duct were determined in comparison with the main port...

abstract the intraparenchymal schwannomas are very rare tumors with only 52 reported cases . we describe a 38 years old man with eight months history of poorly controlled seizures despite of medical therapy. on brain ct scan a 1.5 x 1.5 cm hypodense enhancing lesion was seen in right posterior-inferior frontal lobe. on brain mri the lesion was hypointense in t1 and hyperintense in t2 with homog...

The design of thin-walled cylinders in axial compression is limited by sensitivity to geometric imperfections. This paper focuses on reducing this imperfection from a perspective. By using variable-angle composites, the load paths are tailored reduce effective area over which imperfections can initiate buckling. Continuous Tow Shearing (CTS) one such manufacturing technique. It does not cause d...

Holte, R., L. Rosier, I. Tulchinsky and D. Varvel, Pinwheel scheduling with two distinct numbers, Theoretical Computer Science 100 (1992) 1055135. “The Pinwheel” is a real-time scheduling problem based on a problem in scheduling satellite ground stations but which also addresses scheduling preventive maintenance. Given a multiset of positive integers A = {aI, a,, _.., a,}, a schedule S for A is...

Two Japanese Polypedilum species including a new species are redescribed and described based on the males. Polypedilum (Probolum) simantokeleum, Sasa, Suzuki et Sakai, 1998, is transferred to the subgenus Uresipedilum. Polypedilum (Uresipedilum) dissimilum sp. nov. is easily distinguished from other members of Uresipedilum by having a T-shaped tergal band. Definition of the subgenus Probolum is...

A stochastic forming simulation procedure is developed and implemented to investigate the effect of geometric variability in pre-impregnated woven textiles on manufacturing. Image analysis is used to characterise variability in tow directions and unit cell size in a pre-impregnated carbon/epoxy satin weave textile. It is found that variab ility in tow orientations is significant, whereas variab...
