The bio barcode silica nanotubes (SNTs) was developed to detect pathogenic bacteria using quantum dots and beacon-type capture probe. Various quantum dots were embedded in SNT (QD-SNT) to generate a barcoding signal with different colors and orders. The QD-SNT was coated by colloidal gold nanoparticle to immobilize hairpin structured capture probe on outer walls. Pathogenic specific capture pro...

Recent developments in smartphone technology have increased user demand for indoors applications. The Global Navigation Satellite System (GNSS) and the Inertial Navigation System (INS) are the two advanced systems for navigation technology. However, it is still difficult for GNSS to provide an accurate and practical navigation solution, especially in environments with little or no signal availa...

MicroRNAs (miRNAs) are small, noncoding RNAs that post-transcriptionally regulate gene expression and are recognized for their roles both as modulators of disease progression and as biomarkers of disease activity, including neurological diseases, cancer, and cardiovascular disease (CVD). Commonly, miRNA abundance is assessed using quantitative real-time PCR (qRT-PCR), however, qRT-PCR for miRNA...

Location information of sensor nodes in wireless sensor networks (WSNs) is very important, for it makes information that is collected and reported by the sensor nodes spatially meaningful for applications. Since most current sensor localization schemes rely on location information that is provided by beacon nodes for the regular sensor nodes to locate themselves, the accuracy of localization de...

Previous studies have shown that roundabouts - especially multilane roundabouts - pose accessibility challenges to pedestrians with vision impairments, in part due to a lack of yielding by drivers, especially on multilane roundabout exit legs. In this study, three different treatments are assessed in terms of their propensity for increasing driver yielding rate using a driving simulator. These ...

The number of older people is increasing in many countries. By 2030, it estimated that 15% the overall population will be comprised aged 65 and above. Hence, monitoring tracking elder activities to ensure they live an active life has become a major research topic recent years. In this work, elderly sub-activity system developed detect based on their physical indoor location. location combined p...

In wireless networks, every node needs to keep its neighbors’ link connectivity originated from periodic beacon messages in order to maintain the best route and forward packets along the path. Especially, wireless sensor networks should be working under low power constraint, so retransmission should be restricted in WSN as far as it can [2]. Moreover, low power wireless link makes the connectiv...

This paper proposes novel algorithms for synchronizations and time resolution improvements of One Way Propagation Time (OWPT) measurement in the 802.11 Wireless Local Area Network (WLAN). In OWPT measurement, the Mobile Station (MS) records each 802.11 Beacon frame’s arrival time. The Beacon frame’s arrival time minus its Timestamp, which is recorded when the Beacon frame is transmitted from an...
