Installing optical connectors in FTTx network usually involves field-installable connectors employing mechanical splices. Fujikura has developed a field-installable fusion splice connector that is easy to install and of high reliability.
Conventional context aware services have been built in an ad-hoc manner, making it difficult to build new applications or evolve existing ones. In this paper, we show a sensor proxy based service coordination framework named CASTANET. A CASTANET server serves as a protocol conversion gateway in the network so that different resources in heterogeneous networks can be easily coordinated based on the...
Context-aware services are one of the key applications in the ubiquitous computing environment where physical and virtual information are seamlessly integrated across the network. However, so far we have found few discussions on architectural styles for such integration of wireless sensor networks and other networks services and objects. Conventional context aware services have been built in an ad-hoc...
Older people with dementia often decline in short-term memory and forget what to do next to complete their activities of daily living (ADLs), such as tea-making and tooth- brushing. Therefore, they need caregivers to remind they what to do to complete these activities. However, the steady growth of aging population makes the (relatively) shortage of traditional care resources more and more serious...
This paper concerns a novel method of minimizing loss and stabilizing fusion splicing performance under any atmospheric conditions. A feedback loop is used to relate the luminosity of the splice with arc current and time.
A unified structural analysis method is developed in order to take into account the histories of corrosion loss of material and repair on their long-term mechanical performance of steel structures in addition to the histories of the damages caused by excessive external loads, e.g. big seismic loads. This analysis method is characterized by the point that the volume change in material due to corrosion...
