We consider the self-calibration problem for a moving camera whose intrinsic parameters are known, except the focal length, which may vary freely across different views. The conditions under which the determination of the focal length’s values for an image sequence is not possible, are derived. These depend only on the camera’s motions. We give a complete catalogue of the so-called critical mot...

This document presents the symbols used in our paper. The symbols are divided into groups according to the sections that follow. Section A.2 presents the spaces. Sections A.3 and A.4 present the notational convention for elements and operations from geometric algebra and statistics, respectively. The convention for elements and operations from set theory is presented in Section A.5. Well known ...

A company must purchase a lot of diverse components and raw material from different upstream suppliers to manufacture or assemble its products. Under this situation the supplier selection has become a critical issue for the purchasing department.The selection of suppliers depends on number of criteria and the challenge is to optimize selection process based on critical criteria and select the b...

The paper presents a resource constrained model of a discrete transportation system that can be used to simulate its operation in presence of faults. The simulation results are used to assess the conditional probability of system failure after a short time after it reaches a specific set of reliability states, i.e. the set of critical states. These are determined as the states when the system i...

A projective invariant generalization of the de Casteljau algorithm is described by using the cross ratio and an auxiliary line. We describe the implicit form of the section conics obtained by the algorithm proposed in this paper. Finally, we show how to construct specific conic sections using this approach.

We introduce the notions of depth and of when a local ring (or module over a local ring) is “S2”. These notions are found in most books on commutative algebra, see for example [Mat89, Section 16] or [Eis95, Section 18]. Another excellent book that is focussed on these ideas is [BH93]. We won’t be focussing on the commutative algebra, but one should be aware, at the very least, that this backgro...

Results on the search for particles decaying into Zγ(→ llγ) are presented. Using roughly 1 fb of data, dileptonplus-photon invariant mass distributions have been examined for an excess over the theoretical predictions. Having observed a good agreement between data and the standard model prediction we set 95% C.L. upper limits on the cross section times branching fraction (σ ×B) of the resonance...

The question in the title is answered with a yes, albeit with a special proviso. In the first place the answer agrees with Pat Suppes' words "there are a number of reasons for moving very slowly to the adoption of a new logic." Secondly, the strategy proposed is not to move to a new logic but to put limitations or filters on Classical Logic when needed. This is based on the conviction that thos...

The teamwork research defines several important concepts regarding the design of agents so that they are in fact able to play as members of a collaborative group. Currently such research has been focused on multiagent domains, where agents have full autonomy to take decisions. However this model is not common in real applications where humans may wish to be in control for critical decisions. Th...

The critical configurations for projective reconstruction from three views are discussed. A set of cameras and points is said to be critical if the projected image points are insufficient to determine the placement of the points and cameras uniquely, up to projective transformation. For two views, the classification of critical configurations is well known the configuration is critical if and o...
