I want to thank the organizers of this conference for their kind invitation to me to present what I consider the important contributions that IEA has made to both research and education over the years. I have been a part of IEA and IEA has been a part of my and my family’s life for over forty years now. It has been an exciting ride, to say the least. Despite my continuous connection with IEA ov...

endurance time (et) method is a relatively new performance-based earthquake method for structural evaluation and design. in this method, the structure is subjected to a gradually intensifying accelorogram(s) and its performance is assessed based on the maximum time duration that it can meet the specified performance objectives. using moment-resisting and braced frames which are rehabilitated by...

The Implementing Agreement This report on long-term R&D needs for wind energy was produced by the Implementing Agreement for Cooperation in the Research and Development of Wind Turbine Systems (IEA R&D Wind), which forms part of a programme of international energy technology collaboration which is undertaken under the auspices of the International Energy Agency (IEA). The IEA is the energy foru...

nal interventions for diagnostic and treatment procedures, such as paracentesis, peritoneal dialysis catheter procedures, tru-cut or fine needle biopsies, manipulation of laparoscopic instruments, insertion of sutures and drains, radiofrequency thermal ablation, abscess drainage, and endoscopic gastrostomy, has increased over the past two decades. Although these procedures can be performed safe...

Effects of some important parameters like impactor effects, plug geometry and initiation points on bonding aluminum tubes to aluminum plugs were studied. The impact velocity and dynamic angle between tube and plug should be precisely managed to achieve an optimum bonding condition. A new explosive bonding technique with the use of two material impactors was proposed. Results are especially suit...
