Photochemical reactions of Re(CO)5Br with Ph2P(S) (CH2)nP(S)Ph2 (n = 1,2,3)

The complexes fac-[Re(CO)3Br{Ph2P(S)(CH 2)nP(S)Ph2}] [1a, n = 1; 2a, n = 2; 3a, n = 3] and [Re2(CO)8Br2{µ-Ph2P(S)(CH 2)nP(S)Ph2}] [1b, n = 1; 2b, n = 2; 3b, n = 3] have been prepared by the photochemical reaction of Re(CO)5Br with Ph2P(S)(CH2)nP(S)Ph2. The products have been characterized by elemental analysis, mass spectroscopy, FT-IR and 31 P-[1H]-NMR spectrometry. The results suggest cis-chelate bidentate coordination of the ligand in fac-1a-3a and cis-bridging bidentate coordination of the ligand between two metals in 1b-3b.National Research Council Canada Ege Üniversitesia Ege University, Faculty of Science, Department of Chemistry, Bomova, 35100, Izmir, Turkey b Steacie Institute for Molecular Sciences, National Research Council of Canada, 100 Sussex Drive, Ottawa, Ontario, Canada, K1A 0R6 -- We thank BP (Turkey) for the provision of the photochemical apparatus and Research Foundation of Ege University for funds.

Cooperative Adaptive Cruise Control Implementation of Team Mekar at the Grand Cooperative Driving Challenge

This paper presents the cooperative adaptive cruise control implementation of Team Mekar at the Grand Cooperative Driving Challenge (GCDC). The Team Mekar vehicle used a dSpace microautobox for access to the vehicle controller area network bus and for control of the autonomous throttle intervention and the electric-motor-operated brake pedal. The vehicle was equipped with real-time kinematic Global Positioning System (RTK GPS) and an IEEE 802.11p modem installed in an onboard computer for vehicle-to-vehicle (V2V) communication. The Team Mekar vehicle did not have an original-equipment-manufacturer-supplied adaptive cruise control (ACC). ACC/Cooperative adaptive cruise control (CACC) based on V2V-communicated GPS position/velocity and preceding vehicle acceleration feedforward were implemented in the Team Mekar vehicle. This paper presents experimental and simulation results of the Team Mekar CACC implementation, along with a discussion of the problems encountered during the GCDC cooperative mobility runs
