Structure from motion (SfM) comprises techniques for estimating 3D structures from uncalibrated 2D image sequences. This work focuses on two contributions: Firstly, a stability analysis is performed and the error propagation of image noise is studied. Secondly, to stabilize SfM, we present two optimization schemes by using a priori knowledge about collinearity or coplanarity of feature points i...

We examine the recently found point of intersection between the Z2 and Z4 orbifold subvarieties in the K3 moduli space more closely. First we give an explicit identification of the coordinates of the respective Z2 and Z4 orbifold theories at this point. Secondly we construct the explicit identification of conformal field theories at this point and show the orthogonality of the two subvarieties.

In this paper, firstly, we point out that access control mechanisms are not suitable in existing commercial Relational Data Base Management Systems (RDBMS). Secondly, the idea of Policy-Driven Role-Based Database Access Control (PDRBDAC) is proposed. Thirdly, the issue of multiple inheritance in a role hierarchy is discussed. Finally, a PROLOG interpreting algorithm for dealing with it is descr...

This paper deals with the use of extra freedom in the exact linearization technique. Firstly, the freedom in choosing the coordinate transformation and nonlinear state feedback for the exact linearization is clarified. Secondly, a controller design strategy for the transient behavior improvement in the presence of impulsive disturbances is shown. Finally, numerical and experimental examples exh...

This paper describes a colour-based recognition system with three novel features. Firstly, the proposed system can operate in environments where spectral characteristics of illumination change in both space and time. Secondly, benefits in terms of speed and quality of output are gained by focusing processing to areas of salient colour. Finally, an automatic model acquisition procedure allows ra...

Firstly, two new kinds of Kronecker decompositions is developed, i.e. KPGD and KPID; Secondly, the sufficient and necessary conditions and algorithms of Kronecker product(KPD), KPGD, and KPID are discussed; At last, some useful properties of the rank of the sum of Kronecker product gemel decompositions are obtained.

This paper deals with a new quantitative model for adaptability evaluation of enterprise information systems (EIS). Firstly, a new evaluation model based on QFD is proposed, and the corresponding evaluation algorithm is given. Secondly, the procedures of EIS adaptability evaluation are discussed. Finally, the application of the evaluation model and algorithm is verified through an example, whic...

It is well known that the fuzzy sets theory can be successfully used in quantum models ([5, 26]). In this paper we give first a review of recent development in the probability theory on tribes and their generalizations – multivalued (MV)-algebras. Secondly we show some applications of the described method to develop probability theory on IF-events.

A study was made pertaining to the variations in sensitivity to inhibitors that may be encountered in industrial deterioration problems. The results indicate that at least three types of variations are involved: first, the variation in sensitivity of different strains, secondly, the variation in sensitivity of an individual strain, and finally, the variation produced by the particular environme...

This study reviews the recent empirical studies on knowledge sharing and personality and diversity. The paper begins with an overview of the concepts of knowledge sharing and personality. Secondly, the Big Five personality traits (openness to experience, agreeableness, conscientiousness, extraversion, and neuroticism) and aspects of diversity (culture and gender) that influence knowledge sharin...
