In ubiquitous networks, Mobile Nodes (MNs) may often suffer from performance degradation due to the following two reasons: (1) reduction of signal strength by an MN’s movement and intervening objects, and (2) radio interference with other WLANs. Therefore, quick and reliable detection of the deterioration of a wireless link condition is essential for avoiding the degradation of the communication quality...
ReRAM has been considered as one of the potential technologies for the next-generation nonvolatile memory, given its fast access speed, high reliability, and multi-level capability. Multiple-layered architectures have been used for several megabit test-chips and memory macros [1–3]. This paper presents a MeOx-based 32Gb ReRAM test chip developed in 24nm technology.
We studied a relationship between a zero moment point (ZMP) and a base of support (BOS) during slipping. ZMP is the point on the ground where no moment may be transmitted about the whole body center of mass (COM). When subjects could walk without slipping, ZMP was located within the BOS at a single support phase. When a fall after a forward slip was observed, the ZMP remained outside of the BOS edge...
Efficiency improvement of dye-sensitized solar cell was conducted in terms of increasing light harvest efficiency of dye-coated TiO2 photoelectrode. To increase light harvest efficiency, light confined effect by light scattering TiO2 particles was applied. TiO2 pastes for photoelectrode were composed of mixture of TiO2 particles of 20-23nm, 50nm and 100 nm in average diameter with different ratios...
