fe2+ ion-selective membrane sensor has been fabricated from polyvinyl chloride (pvc) matrixmembrane containing neutral carrier tetra phenyl porphyrin (tpp) ionophore. the addition ofsodium tetraphenylborate (natpb) and the plasticizer dbp has been found to substantiallyimprove the performance of the sensor. the best performance was obtained with the sensor havinga membrane of composition of tpp...

This paper presents an implementation of sensor performance algorithms in the Real-Time Multi UAV Simulator (RMUS). The RMUS was developed to simulate missions to be performed by the Brumby Mk III UAVs at the Australian Centre for Field Robotics (ACFR). Most typical missions rely on the use of onboard mission sensors, vision in particular. It is therefore important to have an indication of the ...

A potentiometric non-enzymatic sensor using off-chip extended-gate field effect transistor (EGFET) with a ferrocenyl-alkanethiol modified gold electrode is demonstrated for determining the uric acid concentration in human serum and urine. Hexacyanoferrate (II) and (III) ions are used as redox reagent. This potentiometric sensor measures the interface potential on the ferrocene immobilized gold ...

A PVC-membrane ion-selective electrode was constructed for quantitative monitoring of gadolinium(III) ion based on 3-methyl-1H-1,2,4-triazole-5-ylhydrosufide (MTY) as an ion carrier. The electrode performance includes a Nernstian slope of 19.8 ± 0.4 mV per decade across a wide concentration range between 1.0 × 10 and 1.0 × 10 M and a detection limit of 7.3 × 10 M. The best performance was obtai...

In this paper, we intend to focus on the sensor network applications in firefighting. A distributed algorithm is developed for the sensor network to guide firefighters through a burning area. The sensor network models the danger of the area under coverage as obstacles, and has the property to adapt itself against possible changes. The protocol developed, will integrate the artificial potential ...

In this paper, homogeneous, wavelength shift biosensor is designed for sensing the protein concentration using two dimensional Photonic Crystal Ring Resonator (PCRR). The sensor is designed to monitor the protein concentration from 0% to 100%. The proposed sensor is composed of periodic Si rods embedded in an air host with a circular PCRR that is placed between the inline quasi waveguides. It i...

A fluorescence magnetic biosensor for the DNA methyltransferase activity was developed based on the cooperative amplification by combining the magnetic nanoparticles synergistic exonuclease III (Exo III)-assisted circular exponential amplification and a supramolecular structure ZnPPIX/G-quadruplex. First, a duplex DNA probe, which was constructed by the hybridization of a quadruplex-forming oli...

Authentication in low power devices is still considered to be an expensive process. CertificateLess Signature is one of the approaches to facilitate authentication in these devices. Wireless Sensor Networks (WSNs) are such low power inexpensive networks, which needs authentication of message. In this paper, a CertificateLess Signature proposed by Gong et al. is analyzed and an approach is being...
