In this paper, a novel localization approach based on the use of a mobile beacon is proposed for wireless sensor networks. The localization system consists of a mobile beacon and beacon receiving modules on each sensor node for measuring distance. The localization is based on the application of multidimensional scaling technique and a local map registration approach. The approach is designed to...

Molecular beacon deoxyribonucleic acid computing is new research focus of intelligent control theory in recent years, it is also new bionic algorithm. It is well known that a very important problem how to determine or tune the proportional integral derivative controller parameters, because these parameters have a great influence on the stability and the performance of the control system. Parame...

Forty-nine samples with known C2V3 sequences were used for the evaluation of an env-based molecular beacon assay to distinguish between the two genetic subclusters C and C' which characterize the HIV-1 epidemic in Ethiopia. Two subcluster C and two subcluster C' beacons targeting two different loci in the C2V3 region were developed. Using a three beacon-based (2C and 1C'=C prime), isothermal am...

Recently, research on sixth-generation (6G) networks has gained significant interest. 6G is expected to enable a wide-range of applications that fifth-generation (5G) will not be able serve reliably, such as tactile Internet. Additionally, offer Terabits per second (Tbps) data rates, 10 times lower latency, and near 100% coverage, compared 5G. Thus, expand across all available spectrums includi...

A bifunctional derivative of the thrombin-binding aptamer with a redox-active Fc moiety and a thiol group at the termini of the aptamer strand was synthesized. The ferrocene-labeled aptamer thiol was self-assembled through S-Au bonding on a polycrystalline gold electrode surface and the surface was blocked with 2-mercaptoethanol to form a mixed monolayer. By use of a fluorescent molecular beaco...

In the Universal Traffic Management Systems (UTMS) now being studied and developed in Japan, the infrared beacon (referred to as IR beacon from now on) is used for realizing the Dynamic Route Guidance System (DRGS) in real world. In DRGS, the IR beacon receives an optional destination information a driver specified, and immediately sends back to the vehicle the dynamic route guidance informatio...

Millimeter-wavelength Rayleigh scattering from water droplets in a cloud is proposed as a means of generating a bright beacon for measuring the surface profile of a radio telescope. A λ=3  mm transmitter, with an output power of a few watts, illuminating a stratiform cloud, can generate a beacon with the same flux as Mars in 10 GHz bandwidth, but the beacon has a narrow line width, so it is ext...

Localization based on received signal strength indication (RSSI) is a low cost and low complexity technology, and it is widely applied in distance-based localization of wireless sensor networks (WSNs). Error of existed localization technologies is significant. This paper presents the N-times trilateral centroid weighted localization algorithm (NTCWLA), which can reduce the error considerably. C...

A universal sensing platform for fluorescence turn-on detection of biomolecules is developed based on Fenton reaction triggered molecular beacon cleavage. Due to its high quenching efficiency, molecular beacons (MBs)-based sensing systems usually show low background fluorescence and large signal-to-background ratio. Glucose is chosen as a model biomolecule for constructing an MB-based fluoresce...

Stanford’s Integrity Beacon Landing System uses ground-based pseudo-satellite transmitters known as Integrity Beacons to resolve carrier phase ambiguities on final approach, giving IBLS both high integrity and centimeter-level accuracy. This paper discusses two improved Integrity Beacon designs and the results of flight tests with these new beacons. The original Integrity Beacons were not synch...
