Gain and time-constant factors shift the inverse process relative to its feedback controller. A new robustness plot cross-graphs these shift factors that take the loop to the stability boundary as a function of frequency.

The estimation of the perceived tempo is required in many MIR applications. However, automatic tempo estimation itself is still an open problem due to the insufficient understanding of the inherent mechanisms of the tempo perception. Published methods only use the information of rhythm pattern, so they may meet the half/double tempo error problem. To solve this problem, We propose to use statis...

In this paper, we have developed the scoring system that scores short answers based on the score table updated by average scores of non-existing answers. The accuracy and the consistency are very important, because the score influences a life. Automatic mark systems have consistency but need more accuracy. In the paper and pencil, a consistency is difficult to maintain. To achieve accuracy and ...

Biped robots form a subclass of legged or walking robots. The study of mechanical legged motion has been motivated by its potential use as a means of locomotion in rough terrain, as well as its potential benefits to prothesis development and testing. This paper concentrates on issues related to the automatic control of biped robots. More precisely, its primary goal is to contribute a means to p...

This paper deals with the stabilization of a rotating body-beam system with torque control. The system we consider is the one studied by Baillieul and Levi in [1]. In [12] it has been proved by Xu and Baillieul that, for any constant angular velocity smaller than a critical one, this system can be stabilized by means of a feedback torque control law if there is damping. We prove that this resul...

This paper presents a new development in the forensics of software copyright through a juxtaposed comparison between the proven AFC test and the recent POSAR test, the two forensic procedures for establishing software copyright infringement cases. First, the paper separately overviews the 3-stage, linear sequential AFC test and then the 5-phase, cyclic POSAR test (as AFC’s logical extension). T...

Previous results about input to state stabilizability are shown to hold even for systems which are not linear in controls, provided that a more general type of feedback be allowed. Applications to certain stabilization problems and coprime factorizations, as well as comparisons to other results on input to state stability, are also briefly discussed. Appeared as: “Further facts about input to s...

Past studies in the IT outsourcing area have examined the management of IT outsourcing relationships from a variety of perspectives. The present paper extends this line of research. In this study, we take a multi-theoretic perspective to explore factors that determine the duration of continuing IT outsourcing relationships between vendor and client firms. Five ex-ante and two expost factors tha...
