Micro and Nanotechnologies going Eastern Europe through Networking INCO-CT-2004 -510470 Project Objectives MINAEAST-NET is intended to be a tool for achieving a better integration of eight ACCs (Romania, Hungary, Poland, Slovenia, Slovakia, Lithuania, Bulgaria and Turkey), in projects for FP 6 on Micro and Nano Technologies. • MINAEAST-NET will be established as the premier source of information about resources and results in MNT from ACCs and about the strong points of the ACC organisations. • Organisations and companies from MS (and world-wide) that are looking for partners in MNT for any kind of projects, should address their needs to MINAEAST-NET and MINAEAST-NET will definitely find the best partner suited for them. Acad. Dan Dascalu, Project coordinator Email: dascalu@imt. ro www. imt. ro • For all MNT interested organisations from ACC, MINAEAST-NET will be the main source of MNT specific project and partnership information: MNT related information about EC calls, international networking activities, partnership search from abroad. Turkey contact point: • MINAEAST-NET will support interaction between ACC and MS organisations to initiate FP 6 proposals through organising meetings, workshops and support travel cost. Yasar Gurbuz, Sabanci University www. sabanciuniv. edu Email: yasar@sabanciuniv. edu • MINAEAST-NET will also be the little helper with any questions concerning proposal set-up and regulations for ACC organisations all that especially for MNT.

Ultra Wide Band (UWB) Wall Penetrating Radar • Ultra wideband technology has its origins in the development of time domain (impulse response) techniques for the characterization of linear, time invariant microwave structures. • A short pulse in time has a large bandwidth in frequency domain hence it is called ultra wide band waveform. • UWB radar also uses radiated and reflected electromagnetic waves to detect, locate and identify targets. • The advantage of using UWB waveforms for radar include better spatial resolution, detectable materials penetration, easier target information recovery from reflected signals and lower probability of interference than with the narrowband signals. • Here we are developing a hand held behind the wall moving object/persons detector for intelligence and surveillance. Same system can also be used for people detection under the ruins after an earthquake for example…. MICROELECTRONICS GROUP
