Currently, the leading Russian oil companies engaged in the development of automatic control systems (ACS) oil equipment, to improve its efficiency. As an example of an object needed to optimize its work, a centrifugal pumping unit (CPU) can be specified. Frequency actuators provide an opportunity to run CPU in any algorithm, and many industrial controllers, are part of the automatic control sy...

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...

purpose: the aim of this study is to analyze the theoretical foundations, the concept, documentation history, steps and the procedure of documentation of knowledge on the basis of life cycle of organizational knowledge and the introduction of automatic and semi-automatic operational strategies of the extraction of tacit knowledge and coding or the representation of explicit knowledge. methodolo...

Abstract In recent 70 years, the artillery aiming control technology has developed rapidly, and mode experienced development process of manual, semi-automatic full-automatic. The new generation system in future is still stage research exploration, with relatively few results lack systematicness. This paper analyzed related technologies mode, puts forward an intelligent autonomous basic concept ...

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...
