    This report was compiled for the Belgian Federal Office for Internal Affairs. It contains a discussion of the creation and subsequent application of a test battery and questionnaires for assessing the physical and mental capacity of firemen. There are currently no uniform criteria for these in Belgium. They are coupled to a scientifically-based training programme.Autorzy zamieszczonego poni偶ej artyku艂u udowadniaj膮, 偶e kwestia predyspozycji psychofizycznych stra偶ak贸w ma wymiar uniwersalny . podobny w ka偶dym kraju. Fakt, i偶 przydatno艣膰 do s艂u偶by determinowana jest w jednakowym stopniu sprawno艣ci膮 i wytrzyma艂o艣ci膮 fizyczn膮 oraz cechami psychiki, potwierdza zar贸wno praktyka, jak i badania naukowe. Na zlecenie rz膮du Belgii (Federalnego Biura Spraw Wewn臋trznych), grupa naukowc贸w pod kierunkiem prof., prof. Lode Godderis'a i Veerle Hermans'a, opracowa艂a jednolite kryteria oceny przydatno艣ci stra偶ak贸w i kandydat贸w na stra偶ak贸w. Ciekawy jest spos贸b podej艣cia do problemu. Diagnoza dokonana przez belgijsk膮 administracj臋 rz膮dow膮 by艂a jednoznaczna - brakuje jednolitych kryteri贸w oceny predyspozycji do pe艂nienia odpowiedzialnej i zwi膮zanej z szeregiem ryzyk, s艂u偶by w stra偶y po偶arnej. Celowo pisz臋 "s艂u偶by", a nie "pracy", bo nawet laik zdaje sobie spraw臋, 偶e stra偶ak - to nie jest zaw贸d podobny do innych. Wielu twierdzi wr臋cz, 偶e trzeba mie膰 do niego powo艂anie. Zostawmy metafizyczne rozwa偶ania. Nie spos贸b jednak zaprzeczy膰, 偶e w tej s艂u偶bie sprawdz膮 si臋 ludzie, kt贸rzy charakteryzuj膮 si臋 odpowiednimi cechami cia艂a, umys艂u i psychiki. Jakimi? Aby odpowiedzie膰 na to pytanie, wybrano najprostszy i najskuteczniejszy, moim zdaniem, spos贸b - zlecono wybitnym specjalistom (naukowcom i wspieraj膮cym ich praktykom) zrealizowanie projektu naukowo-badawczego. Jak im si臋 to uda艂o

    Demonstrator Testbed for Intra-Chip Optical Interconnections: Combining Multi-Channel Free-Space Plastic Micro-Optical Modules and VCSEL Based OE-FPGAs.

    We fabricated and replicated in semiconductor compatible plastics a multi-channel free-space optical interconnection module designed to establish intra-chip interconnections on an Opto-Electronic Field Programmable Gate Array (OEFPGA). The micro-optical component is an assembly of a refractive lenslet-array and a high-quality microprism. Both components were prototyped using deep lithography with protons and were monolithically integrated using a vacuum casting replication technique. The resulting 16 channel module shows optical transfer efficiencies of 50% and inter-channel cross-talks as low as -22 dB. These characteristics are sufficient to establish multi-channel intra-chip interconnects with OE-FPGA's. The OE-FPGA we used was designed within a European co-founded MEL-ARI consortium working towards a manufacturable solution for optical interconnects between CMOS IC's. The optoelectronic chip combines fully functional FPGA digital logic with the drivers, receivers and flip-chipped optoelectronic components. It features 2 optical inputs an 2 optical outputs per FPGA cell, amounting to 256 photonic I/O links based on multi-mode 980 nm VCSELs and InGaAs detectors. With a careful alignment of the micro-optical free-space module above the OE-VLSI chip, we demonstrated for the first time to our knowledge a multi-channel free-space intra-chip optical interconnection. Data-communication was achieved with 4 simultaneous channels working at 10Mb/s. The bitrate was limited by the chiptester. Notwithstanding the use of non-aggressive 0.6 mum CMOS technology the FPGA will provide an 80 Mbit/s information rate per channel using manchester encoded links. The whole chip therefore has in principle a peak aggregate signalling rate of approximately 20 GBit/s. This first demonstration paves the way for a practical solution to solve the electronic intra-chip, interconnect bottleneck with low-cost mass-producible chip-compatible plastic micro-optical modules

    A multi-channel free-space micro-optical module for dense MCM-level optical interconnections has been designed and fabricated. Extensive modeling proves that the module is scalable with a potential for multi-Tb/s.cm2 aggregate bit rate capacity while alignment and fabrication tolerances are compatible with present-day mass replication techniques. The micro-optical module is an assembly of refractive lenslet-arrays and a high-quality micro-prism. Both components are prototyped using deep lithography with protons and are monolithically integrated using vacuum casting replication technique. The resulting 16-channel high optical-grade plastic module shows optical transfer efficiencies of 46% and inter-channel cross talks as low as -22 dB, sufficient to establish workable multi-channel MCM-level interconnections. This micro-optical module was used in a feasibility demonstrator to establish intra-chip optical interconnections on a 0.6gm CMOS opto-electronic field programmable gate array. This opto-electronic chip combines fully functional digital logic, driver and receiver circuitry and flip-chipped VCSEL and detector arrays. With this test-vehicle multichannel on-chip data-communication has been achieved for the first time to our knowledge. The bit rate per channel was limited to 10Mb/s because of the limited speed of the chip tester
