This paper proposes Travel Prediction-based Data forwarding (TPD), tailored and optimized for multihop vehicle-to-vehicle communications. The previous schemes forward data packets mostly utilizing statistical information about road network traffic, which becomes much less accurate when vehicles travel in a light-traffic vehicular network. In this(More)
This paper proposes a framework for security services using Software-Defined Networking (SDN) and Interface to Network Security Functions (I2NSF). It specifies requirements for such a framework for security services based on network virtualization. It describes two representative security systems, such as (i) centralized firewall system and (ii) DDoS-attack(More)
To synthesize a thermally robust Ni1-xPtxSi film suitable for ultrashallow junctions in advanced metal-oxide-semiconductor field-effect transistors, we used a continuous laser beam to carry out millisecond annealing (MSA) on a preformed Ni-rich silicide film at a local surface temperature above 1000 °C while heating the substrate to initiate a phase(More)
Two different methods are used to evaluate the performance of the consumption-based asset pricing models to explain the cross-section of expected stock returns in conditional moments: one is to scale the returns, and the other is to model time-varying factor loadings, using instrument variables. Maximum correlation portfolios are constructed to directly(More)
This paper introduces an optimal path finding problem for drone battery charging where their batteries should be charged for the travel from a source to a destination as needed. We present a practically reasonable heuristic to solve the problem by monitoring drones' battery status and traffic conditions in real time through a cloud-based service called(More)
In a model, two players, heterogeneous in their information quality, compete with each other with perfect information about the other player’s information quality. If they can decide their timings of actions endogenously, the less-informed player has an incentive to delay her action for learning. On the other hand, the more-informed player wants to delay(More)
With the development of smart devices supporting VR (Virtual Reality) and AR (Augmented Reality), users' input devices are changing to wearable devices. The existing input devices for gesture recognition were relatively rigid. In this research, we propose a gesture recognition device by using a flexible substrate to manufacture a device that can be used in(More)
Excited state intramolecular proton transfer (ESIPT) of 1-hydroxy-2-acetonaphthone (HAN) has been in controversy, mainly because its Stokes shift is small compared to those of typical ESIPT molecules. We have investigated excited state dynamics of HAN by time-resolved fluorescence with a resolution high enough to record the nuclear wave packet motions in(More)
