Moores Law states that the number of active components on an microchip doubles every 18 months. Variants of this Law can be applied to many measures of computer performance, such as memory and hard disk capacity, and to reductions in the cost of computations. Remarkably, Moores Law has applied for over 50 years during which time computer speeds have increased by a factor of more than 1 billion! This remarkable rise of computational power has affected all of our lives in profound ways, through the widespread usage of computers, the internet and portable electronic devices, such as smartphones and tablets. Unfortunately, Moores Law is not a fundamental law of nature, and sustaining this extraordinary rate of progress requires continuous hard work and investment in new technologies most of which relate to advances in our understanding and ability to control the properties of materials. Computer software plays an important role in enhancing computational performance and in many cases it has been found that for every factor of 10 increase in computational performance achieved by faster hardware, improved software has further increased computational performance by a factor of 100. Furthermore, improved software is also essential for extending the range of physical properties and processes which can be studied computationally. Our EPSRC Centre for Doctoral Training in Computational Methods for Materials Science aims to provide training in numerical methods and modern software development techniques so that the students in the CDT are capable of developing innovative new software which can be used, for instance, to help design new materials and understand the complex processes that occur in materials. The UK, and in particular Cambridge, has been a pioneer in both software and hardware since the earliest programmable computers, and through this strategic investment we aim to ensure that this lead is sustained well into the future.


A pulley device for a belt or chain, the pulley device comprising a bearing provided with an external ring, an internal ring, and at least one row of rolling elements mounted in a bearing chamber defined between the external and internal rings. A pulley is secured in rotation with the external ring and provided with an external radial surface for engaging with a belt or chain. Also included is at least one hollow shaft able to receive a screw for mounting the pulley device on a support. The hollow shaft forming a structural unit comprising a bushing, a flange secured to the bushing, and which extends, from the bushing, radially outwards, respective to a central axis of the hollow shaft, as far as the bearing chamber. The flange is formed with a washer and an endplate, while the washer is radially located between the bushing and the endplate.

A bearing unit for pinions, in which a pinion is rotatably supported through the bearing unit from the bearing unit itself. The pinion is mounted projecting from the bearing unit. The bearing unit is provided with a single outer ring with two raceways, an inner ring defined by a spacer and by two half-rings disposed on opposite sides of the spacer axially aligned with each other and each having a respective raceway. Two rows of balls are arranged inside of the raceways, where the diameters both of the rows of balls, and the balls themselves are different from each other depending on the proximity or otherwise of the row to the head of the pinion.


A suspension bearing device, comprising: a bearing, a lower cup and an upper cup centered on a central axis. The lower cup having a body including a tubular axial portion and an annular outward radial portion. The lower cup is provided with a damper pad including: an inner portion disposed against the annular outward radial portion of the body; an outer portion for bearing a suspension spring; and an annular recess for receiving a creep of material of the damper pad when the outer portion is constrained by the suspension spring. The suspension bearing device can be integrated into a motor vehicle. A method for manufacturing such a suspension bearing device.


A suspension bearing device, comprising a bearing, a lower cup and an upper cup centered on a central axis. The lower cup includes a body having a tubular axial portion and an annular outward radial portion.
