Submarines: Corrosion Protection or Enemy Detection?

David Schaefer
University of Duisburg-Essen, Duisburg, Germany

Germany's Technical Center for Ships and Naval Weapons, Bundeswehr, Germany

Submarines create underwater electric potential (UEP) signatures when using corrosion protection systems. These signatures are detectable by enemy vessels, an undesirable effect of the corrosion protection. Germany’s Technical Center for Ships and Naval Weapons (WTD 71) has worked with the Laboratory for General and Theoretical Electrical Engineering (ATE) at the University of Duisburg-Essen to ...

A Smooth Optical Surface in Minutes

Anthony Beaucamp
Zeeko Ltd
Leicestershire, UK

Zeeko Ltd is a technology company that manufactures corrective polishing machines for optics and other surfaces. They are presently researching fluid jet polishing (FJP), which pumps a mixture of water and abrasive particles through a nozzle onto a work piece. Unfortunately, FJP tends to introduce waveforms on to the polished surfaces, which in turn causes serious problems with optics. It is ...

Current Transformer Design That Combines Finite Element Analysis and Electric Circuit Simulation

Dr. Rolf Disselnkötter
ABB AG, Ladenburg, Germany

Transformers have been around for quite a while but their fundamentals are still being investigated by ABB in Ladenburgh, Germany. The ABB Corporate Research Centre is currently developing sophisticated magnetic sensors, using finite element analysis (FEA) to investigate the way in which external electrical sources and loads impact a magnetic subsystem like a transformer core. Their goal is to ...

Modeling Optimizes a Piezoelectric Energy Harvester Used in Car Tires

Alexander Frey and Ingo Kuehne
Siemens Corporate Technology, Munich, Germany

Siemens is a technology company working with electronics and electrical engineering in industry, energy, and healthcare. Researchers at Siemens Corporate Technology are experimenting with an energy harvesting MEMS (Micro Electro-Mechanical System) generator.

Fabio Alves and Gamani
Naval Postgraduate School
Monterey, CA

Metamaterials are manufactured, structured materials that they can interact and manipulate wave phenomena such that objects surrounded by metamaterials are shielded from these waves. In the case of light, metamaterials make these objects ‘invisible’. Researchers throughout the world are applying these materials to many different applications. At NASA Glen Research Center, physicists are ...

Numerical Simulation-Based Topology Optimization Leads to Better Cooling of Electronic Components in Toyota Hybrid Vehicles

Toyota Research Institute of North America, MI, USA

The Toyota Research Institute in Ann Arbor drives cutting-edge research in energy efficiency, mobility infrastructure, and safety. Here, Ercan Dede and his team are designing heat sinks (or cold plates), which are affixed to fragile electrical systems and other applications in Toyota’s hybrid vehicles. Their simulations simulate the cold plate’s topology for improved cooling efficiency while ...
