This paper describes a practical several moving objects area extraction using a half-cosine function wavelet network. The network decomposes an image into weighted basis functions corresponding to spatial frequency. In this method, objects are distinguished by using a difference of object's size. First, moving objects area can be extracted from the weight image of the basis functions which constructs...
The paper proposes a rear-end collision warning system for drivers, where how to evaluate the risk of collision is critical. In the proposed system, the time-to-collision assuming a constant relative acceleration is employed as a subjective index of risk based on the collected data in an unconstrained drive and the discussion from a theory of visual control. The system produces an alert when it detects...
With conventional regression test tools for Web applications, it is difficult to specify the values to be verified that are repeatedly output inside loop statements. This paper presents a method that automates a regression test of a Web application on the server side. This method makes it easy to specify values to be verified when we develop Web applications, and enables us to directly check the verification...
We investigated the influence of extremely high doping concentrations on the sheet resistance of ion implants annealed by FLA. As the implant depth was ultra-shallow and the amount of dopant atoms high, the concentration of dopant near the surface was exceedingly high, above the solid solubility limit, resulting in high Rs. The cause of this is mainly due to the formation of clusters, which was confirmed...
This paper proposes a method for generating a Web-page based troubleshooter, which diagnoses troubles about computer system administration. This troubleshooter digs out several possible causes (hypotheses) from the current status of a trouble, and then examines those hypotheses in turn. After the cause is identified, it will present a solution to fix the trouble. To illustrate the status of a trouble,...
This paper presents high-level functional Web components, which conventional development environments for Web applications have not yet supported. The high-level functional Web components sum up various kinds of data in two dimensions as in Microsoft Excel. These components reduce the amount of code to be written by developers greatly. The paper also describes the system that implements these high-level...
Ankle-foot orthoses (AFOs) are orthotic devices supporting movements of ankles of disabled persons for example hemiplegia, polio, peroneal nerve palsy, etc. In our previous research, we developed some kinds of passive controllable AFO which can control ankle torque with Compact Magnetorheological fluid brakes. One of the remarkable key points of its control is damping control at initial contacts....
In this paper, bias-compensated least squares (BCLS) method is proposed in order to estimate a plant under feedback control when the noise is colored. The feedback controller is assumed to be linear time invariant discrete-time system and the feedback system is assumed to be asymptotically stable. The aim of the proposed method is to reduce the computational cost which will be required for the conventional...
We evaluated profiles of B, P, As, and Si implanted in Ge substrates by secondary ion mass spectrometry, analyzed the profile data using a quasi-crystal Lindhard-Scharff-Schiott (QCLSS) theory, tuned its parameters, and established a corresponding database based on a tail function. We also predicted Ge, Sb, Ga, In, and Xe profiles in Ge substrates by using the QCLSS theory and also established a corresponding...
