In this study we will show that the research on Nversion high-reliability software structures can be extended to neural networks architecture. In addition, we will explore the possibility of applying this structure to a spacecraft tracking problem. One such system is the Automated Spacecraft Monitoring System (ASMS), a beacon-monitoring or detection system. Four neural networks, each trained fo...

In this paper, we consider a heterogeneous power network (HPN) where an electric-supplied sink uses much higher transmission power than battery-supplied nodes. The HPN potentially enables the sink to directly cover the whole area (i.e., all nodes are within one hop transmission range of the sink). Based on the characteristics, we design a fast and light collection protocol (FLC). FLC allows the...

This study describes a sensitive in-cell protease detection system that enables direct fluorescence detection of a target protease and its inhibition inside living cells. This live-cell imaging system provides a fluorescent molecular beacon protein comprised of an intracellular translocation signal sequence, a protease-specific cleavage sequence, and a fluorescent tag sequence(s). The molecular...

In this paper, we propose a mobile physiological sensor that works with an indoor positioning system based on a wireless sensor network. The physiological sensor is a small, mobile, multi-sensor device which includes electrocardiograph, 3-axis accelerometer, barometer, thermometer, and hygrometer. In addition, the device is a network node of a wireless sensor network and receives beacon signals...

Localization is one of the most important issues associated with underwater acoustic sensor networks, especially when sensor nodes are randomly deployed. Given that it is difficult to deploy beacon nodes at predetermined locations, localization schemes with a mobile beacon on the sea surface or along the planned path are inherently convenient, accurate, and energy-efficient. In this paper, we p...

In Stage 1 of 4 experiments in which rats completed a water-maze blocking procedure, experimental groups were trained to use a predictive beacon (hanging above, connected to, or displaced from the platform) to find a submerged escape platform in the presence of predictive or irrelevant background cues and in the presence or absence of irrelevant landmarks. In Stage 2, a fixed beacon, landmarks,...

Beacon attraction is a movement system whereby a robot (modeled as a point in 2D) moves in a free space so as to always locally minimize its Euclidean distance to an activated beacon (also a point). This results in the robot moving directly towards the beacon when it can, and otherwise sliding along the edge of an obstacle. When a robot can reach the activated beacon by this method, we say that...

This paper is on a novel use of lighting or signaling devices constructed by light-emitting diodes (LEDs) as a positioning beacon. The idea is that the surface of the LED lighting device is divided into regions and used to show different visual patterns that are not noticeable by the human eye due to the high-frequency switching of the LEDs. A digital camera is used as a receiver to capture a s...

Homogeneous assays based on real-time fluorescence monitoring during PCR are relevant alternatives for large-scale genotyping of single-nucleotide polymorphisms (SNPs). We compared the performance of the homogeneous TaqMan 5'-nuclease assay and the Molecular Beacon assay using three SNPs in the human estrogen receptor gene as targets. When analyzing a panel of 90 DNA samples, both assays yielde...

In an infrastructure Basic Service Set (BSS) beacon frames are transmitted periodically by the Access Point (AP) and announce the presence of a wireless network. It mainly consists of network specific information and thus one of its main purposes is the "advertisement" of this information. Based on this information mobile devices can take many decisions, for example, whether to attempt associat...
