This paper demonstrates the low-energy operation of a two-phase clocked adiabatic static CMOS logic (2PASCL) on the basis of the results obtained in the simulation of a 4-bit ripple-carry adder (RCA) and D-flipflop employing 2PASCL circuit technology. Two-phase unsymmetrical power supply clocks are introduced to increase the logic transition level. Energy dissipation in the unsymmetrical clocked 2PASCL...
Motivated by performance evaluation of a computer communication system, we consider a renewal input, general service time, single-server, and infinite-capacity queuing system with generally distributed time-out threshold. We obtain two moment approximate formulas for the mean system performance measures (including the mean number of customers in the system and the mean response time) by using the...
We consider a single-server GI/G/1 queueing system with modified service mechanism. By modified service mechanism, we mean that the service time distribution (H0) for the customers arriving to find the system idle may be different from the service time distribution (H1) for the customers arriving to find the system busy. We present qualitative relationships among the performance measures in the system...
In this paper, a modeling of frequency depended dielectric dispersive characteristics of transmission line and its step responses are described. A dielectric dispersive characteristic can be shown by complex relative permittivity of medium. The Debye type and the Lorenz type dispersive characteristics are investigated. The equivalent circuit representations of per unit length parameters of the transmission...
A comparison of incorporation schemes of dissipation in the FDTD analysis of transmission lines using stability analysis is described. In the leapfrog type FDTD method, the calculation points of the voltage and the current are different in the time space. Therefore, how dissipation is included in the update equation becomes a problem. We find that incorporation of dissipation by using average value...
We succeeded in growing single crystal of bis[4-dimethylamino-N-methyl-4-stilbazolium] terephthanate (BDAS-TP) by using a solution-slow-cooling technique. We obtained a broadband THz spectrum from BDAS-TP crystal.
A robot working with humans or other robots is supposed to be adaptive to changes in the environment. Reinforcement learning has been studied well for motor skill learning, robot behavior acquisition and adaptation of the behavior to the environmental changes. However, it is not practical that the robot learns and adapts its behavior only through trial and error by itself from scratch because huge...
Estimation of a caregiver's view is one of the most important capabilities for a child to understand the behavior demonstrated by the caregiver, that is, to infer the intention of behavior and/or to learn the observed behavior efficiently. We hypothesize that the child develops this ability in the same way as behavior learning motivated by an intrinsic reward, that is, he/she updates the model of...
This paper describes the concept of an ultra light weight fuel cell electrical vehicle (UL-FCV), and the results of its running experiments. The UL-FCV is a one-person operated fuel cell vehicle designed for ECONO MOVE, a Japanese light weight electrical vehicle competition held every May in Akita, Japan. Vehicles are powered using two 60 NL hydrogen tanks and are evaluated based on the distance traveled...
In this paper, we propose an efficient dynamic topology reconfiguration method for a service overlay network called ACBP (approximate cluster based policy), which does not require detailed information on future traffic requirements.Instead of the detailed information on future traffic requirements, ACBP utilizes community information of a social network among users for roughly estimating traffic requirements...
A double-sided wave absorber with specified reflection and transmission coefficients at both sides is proposed. This wave absorber consists of two transparent dielectric layers with three transparent resistance films. Therefore, this wave absorber is transparent and electromagnetic waves are absorbed in both sides. Then it is suitable for the indoor use as electromagnetic wave separator. The design...
The nursing care quality improvement is very important for our life. Currently, nursing-care freestyle texts (nursing-care data) are collected from many hospitals in Japan by using Web applications. The collected nursing-care data are stored into the database. To evaluate nursing-care data, we have already proposed a fuzzy classification system, a neural network based system, a support vector machine...
A new blind source extraction method in widespread noise conditions is proposed, which is based on multiple frequency-domain independent component analysis (FDICA) combining projection back and spectral subtraction. In addition, We implement the proposed method to digital signal processor (DSP) for a more realistic real-time operation, and develop a new blind source extraction (BSE) microphone which...
The stochastic network calculus receives much attention as a new methodology for end-to-end performance evaluation of networks, taking account of the effect of statistical multiplexing. In this paper, we present a new stochastic network calculus for many flows from an approach like large deviations techniques. In an n-node discrete-time tandem network with L flows, let Amacrthetas (t, s) and - Smacr...
Piezoelectric response force microscopy, PFM, is a kind of SPM technique. It measures the change of the position of surface in accordance with the applied voltage, giving local piezoelectric activity. This method is widely applied to ferroelectric ceramics as well as to ferroelectric polymers. We used this method to study the dynamics of polarization reversal in thin films of VDF/TrFE copolymer.
