We developed Smart Furniture, which extemporaneously converts the legacy non-smart space into a Smart Hot-spot which consists of computational services. Since the Smart Furniture is equipped with networked computers, sensors and various I/O devices, it can provide various services by alone or by coordinating with other devices. In this paper, the physical(More)
Many researchers introduced special rooms equipped with sensors, devices, networks, and computers to demonstrate ubiquitous computing environment. However, the cost and time for building such a room is a barrier to the deployment of various ubiquitous applications. We have developed smart furniture which instantaneously converts the legacy non-smart space(More)
Accurate estimation of elevation is important for many location based services. Although, it is possible to obtain altitude from GPS, its accuracy is unreliable and applicable in outdoors only. It is possible to use barometers on smartphones to estimate elevation in both indoor and outdoor scenarios. To this end, we proposed an integrated framework to(More)
A heterogeneous multi-core processor (HMCP) architecture, which integrates general purpose processors (CPU) and accelerators (ACC) to achieve high-performance as well as low-power consumption with the support of a parallelizing compiler, was developed. The evaluation was performed using an MP3 audio encoder on a simulator that accurately models the HMCP. It(More)
A pervasive computing environment consists of a variety of devices, such as tiny sensor nodes, handheld devices, consumer electronics, and PCs, which are capable of communicating with others via a communication platform like Bluetooth, ZigBee, UPnP, and DLNA. Those devices should be able to communicate one another to provide users with richer pervasive(More)
This study examined age and growth of Japanese flounder Paralichthys olivaceus off the Pacific coast of northern Japan, and determined whether the growth patterns of male and female fish in northern (40–41°N) and southern (37–38°15′N) waters differ. In total 8095 specimens were collected between January 1999 and December 2005. Zonation consisting of opaque(More)
The on-chip fabrication and manipulation of microstructures are expected to be applied for single cell analysis system such as cell manipulation and measurement tools. In this paper, we previously present a methodology for fabricating and assembling microstructures inside a microfluidic channel. By the illumination of patterned UV-ray through the mask under(More)
The biomass of bighand thornyhead Sebastolobus macrochir was increased by the high recruitment success of the 1999–2002 year classes off the Pacific coast of northern Honshu, Japan. In this study, the growth of bighand thornyhead was examined over a 9-year period from 1996 to 2004 in this area. The growth of the 1999 year class and the 2000–2002 year(More)
