The presented article deals with the application of Reverse Engineering and Rapid Prototyp-ing processes in development process automotive industry. In our case, we will focus on design exterior rear view mirror. We obtained information about shape as well data used to model part a virtual CAD computer environment by scanning it Leica laser scanner. point cloud was imported into CATIA V5 softwa...

The current emphasis in second language teaching lies in the achievement of communicative effectiveness. In line with this approach, pronunciation training is nowadays geared towards helping learners avoid serious pronunciation errors, rather than eradicating the finest traces of foreign accent. However, to devise optimal pronunciation training programmes, systematic information on these pronun...

In this paper a methodology based on multi-objective particle swarm optimization algorithm, for identifying the optimal parameters for machining a workpiece with a milling is presented. The time for machining, the material removal rate, and the feed rate were identified as the objectives to optimize. In addition, the proposal considered 4 constraints related to cutting tools, rotating speed of ...

Abstract In this new technological world, CNC and manual turning operations engage in a significant role different types of designing manufacturing industries. Before initiating the processes, analysis is crucial part process. This study involves modelling machining process cylindrical AA6082-T6 workpiece with Tungsten Carbide tip tool. A 3D model first modelled on CATIA V5 then carried Ansys R...

A fixture is designed and built to hold, support and locate every component to ensure that each is drilled or machined with accuracy and manufactured individually. A fixture can be designed for a particular job. A brake spider includes a spider body with a central opening and a slot for receiving a camshaft and bracket assembly. The brake spider is attached to axle housing via the central openi...

The multi-disciplinary nature of complex system, such as aero engines, requires a data structure that considers the behavioural interactions within the system. This paper focuses on the management of simulations models and data, with respect to complex system structure. It is proposed to use model based system engineering (MBSE) methodology to support modelling activities and improve the integr...

Aircraft is a complex structure, but a very efficient man made fly ing machine. An aircraft is a machine that is able to fly by gaining support from the air, or, in general, the atmosphere of a planet. It counters the force of grav ity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet. In this project the flu id–structure inte...

We provide new evidence on the impact of recessions on traffic accidents by exploiting the case of Spain, where the effects of the 2008 economic crisis have been among the strongest in the developed world. We exploit differences in the incidence of the recession across Spanish provinces due to the unequal evolution of the real estate bubble across the territory. We use a unique dataset on the u...
