An MIT study has demonstrated that deterioration in the performance of InGaAs (indium gallium arsenide) transistors at small scales is not an intrinsic property of the material. For computing power to continue to improve into the future, supporting more computationally expensive processes, engineers will need to develop ever-smaller and more densely packed transistors. For decades, … Read more
CEO of EngineeringUK, Dr Hilary Leevers outlines the work being done by her organisation to inspire and engage with ‘tomorrow’s engineers’ in the 11-to-14-year-old age bracket and beyond. “All young people should be enabled to understand what engineering is and be motivated to engage with it as a career pathway,” says Hilary Leevers. It’s a … Read more

Two terms that one often hears in relation to information systems development are methodologies and tools. A methodology is a recommended way of doing something, and a tool is a device for accomplishing a task. Relating these terms to the building of a house, the arhchitect’s blueprint is a methodology (the architect’s recommended way of building … Read more
