A local and temporal separated manufacturing becomes possible, which can enhance the economic efficiency of the production. Complex products such as spacecraft, large CNC Machine, large compressor face challenges in their development process. The cloud manufacturing which is based on the development of cloud computing and Internet of Things system makes the collaborative manufacturing process o...

Process planning plays an important role for ensuring machining quality, reducing production cost, and shortening leading time. Since there are many uncertainty factors for manufacturing resources in a changing manufacturing environment, especially for small batch manufacturing of large scale parts requiring long process planning time, manufacturing companies are facing significant challenges o...

The acceleration of growth and job creation is a major challenge for North African Countries (NAC) which are witnessing a sharp increase in their labour force. The dominance of the textile/clothing sector and of sub-contracting in the automobile sector within the Maghreb’s industrial fabric, as well as the lack of alternative manufacturing specialization are sources of vulnerability. Consequent...

This paper reports on our experiences of using commodity GPUs to speedup the execution of fine-grained concurrent simulations. Starting with an existing process-oriented ‘boids’ simulation, we explore a variety of techniques aimed at improving performance, gradually refactoring the original code. Successive improvements lead to a 10-fold improvement in performance, which we believe can still be...

The Micro-Accelerator Platform is an optical-wavelength microstructure for laser acceleration of particles, currently under development at UCLA. It is a slab-symmetric structure and can be constructed in layers using existing nanofabrication techniques. We present several possible fabrication techniques and preliminary experimental outcomes for manufacturing this structure.

The recursive projection schemes used in most existing recursive methods for solid deformable structure dynamic problems in precision manufacturing systems lead to dense coefficient matrices in the acceleration equations and consequently there is a strong dynamic coupling between the joint and elastic coordinates. When the number of elastic degrees of freedom in engineering materials increases,...
