A new pyrene-based chemosensor (1) exhibits excellent selectivity for Fe3+ ions over a wide range of tested metal ions Ag+, Ca2+, Cd2+, Co2+, Cu2+, Fe2+, Hg2+, K+, Mg2+, Mn2+, Ni2+, Pb2+, and Zn2+. The binding of Fe3+ to chemosensor 1 produces an emission band at 507 nm due to the formation of a Py-Py* excimer that is induced by Fe3+-binding. The binding(More)
This paper introduces four block joint detection (JD) receivers which combining the orthogonal frequency division multiplexing (OFDM) and code division multiple access (CDMA) techniques, i.e., OFDM-CDMA receiver. The performance of the OFDM-CDMA receiver with orthogonal and non-orthogonal spreading sequences is investigated in mobile radio channels. The(More)
—In this paper, the receivers with adaptive equalizer and turbo decoder are investigated for orthogonal frequency division multiplexing-code division multiple access (OFDM-CDMA) systems in multipath channels. The de-spreading equalizer which combines de-spreading and equalization is used to mitigate the MAI and ISI. The stochastic gradient based LMS(More)
The development of car cloud sensor network isbased on the open sources of Hadoop that support themultidimensional information service studies in this paper. Theoverall system is divided into the layers of physical sensorinformation, communications platform, real-world information, aswell as applications to develop. The function of physical(More)
This paper is concerned with the Earliest-DeadlineFirst (EDF) policy for scheduling a constrained multi-queuesystem with a single server in the overloaded environment. Thisstudy originates from the research of the controller area network(CAN). In the CAN system, variability and constraints, e.g. heavy(or overloaded) traffic, timing constraints, limited(More)
