GWEFR has four main activities

GWEFR operational areas

which are outlined below.

Simulation, Modelling & Control

The company can develop bespoke off-line and real-time simulations of physical systems working from the client's description of their plant and its control system, mostly using industry-standard Matlab/Simulink software.

Computer simulation and modelling has been used for many years by large companies and is now making its way down the supply chain. Increasingly there will be a demand from large companies to be supplied, not only with the end-product, but a model of the intended product at a very early stage of development. Typically, this will be integrated into their Simulation Based Design process. However, simulation and modelling is not readily available to many smaller companies, who find it impossible to maintain the required software expertise in-house. GWEFR can help you.

The company offers three generic simulation products:

These generic packages can serve as an affordable introduction to computer simulation for those new to the idea. Click on Products for more information.

Engineering Consultancy

We can perform literature studies, assess the state of the art, suggest solutions, provide recommendations and prepare reports to a high technical standard.

Examples of consultancies we have undertaken are:

The clips on the left show the variety of output that our reports typically contain.

Contract R&D

GWEFR has acted as an Associate Consultant for EA Technology Ltd , a leading supplier of specialist services to the power industry worldwide. Click here to see a case study (~329KB PDF) on how GWEFR helped EA Technology carry out measurements on HV underground cables.

A contract arrangement may be appropriate if you wish to outsource some of your R&D, require skills in a specialist area or need additional short-term effort to supplement your own staff. With their university background, GWEFR staff and associates are experienced in performing applied research and running R&D projects which bring together industrial and academic partners.

Product Design

GWEFR has participated in the KESS scheme by sponsoring Mark Fisher to study for the PhD degree at Bangor University's School of Computer Science. Mark conducted research on an integrated sensor system for a small, electrically-powered UAV (unmanned aerial vehicle) for internal building inspection.

The photograph opposite shows initial tests being performed on a small laser scanner at the university. The grey mesh plot shows the 3D map of the box built up from the range and angle measurements provided by the sensor, once the geometric co-ordinate transformations have been done. The red shape represents the real box position for comparison.

Mark's thesis Integrated sensor suite for indoor building inspection with an unmanned aerial vehicle can be downloaded from Bangor University's e-publication website: Thesis download
