In stereo algorithms with more than two cameras, the improvement of accuracy is often reported since they are robust against noise. However, another important aspect of the polynocular stereo, that is the ability of occlusion detection, has been paid less attention. We intensively analyzed the occlusion in the camera matrix stereo (SEA) and developed a simple but effective method to detect the ...

In this paper we present an effective method for computing certain real coefficients λn which appear in a criterion for the Riemann hypothesis proved by Xian-Jin Li. With the use of this method a sequence of over three-thousand λn’s has been calculated. This sequence reveals a peculiar and unexpected behavior: it can be split into a strictly growing trend and some tiny oscillations superimposed...

E-learning provides an unprecedented flexibility and convenience for e-learners by breaking the limitations of space and time. However, the role of emotion is neglected in current e-learning systems. We focus strictly on negative emotions of e-learners, integrating emotion regulation theories with recommender technique, and present the study of learner-oriented negative emotion compensation in ...

This paper proposes a request-driven role mapping framework for secure interoperation in multi-domain environments. To support flexible policy expression and inter-domain policy mapping, we present a convenient and effective method to perform the privilege query in general hybrid role hierarchies for special external requests based on the minimal unique set (MUS). Role mappings are the basic ap...

Introduction To meet the long-term needs of public health and social development of China, it is in urgency to establish a comprehensive response system and crisis management mechanism for public health emergencies. Syndromic surveillance system has great advantages in promoting early detection of epidemics and reducing the burden of disease outbreak confirmation (1). The effective method to se...

Crushers play an important role in the comminution of minerals and the control of its operation can lead to an increase of the plant throughput and efficiency. This work presents a simple but effective method for controlling a crusher circuit by acting over the feeder and the speed of the conveyor belt carrying out the mineral up to the crusher. Guidelines for tuning the strategy, as well as pr...

Data outsourcing provides companies a cost effective method for their data to be stored, managed, and maintained by a third-party. Data outsourcing offers many economical benefits, but also introduces several privacy concerns. Many solutions have been proposed for maintaining privacy while outsourcing data in the data as plain-text model. We propose a method that can maintain a similar level of...

There are many examples in which a word changes its polarity from domain to domain. For example, unpredictable is positive in the movie domain, but negative in the product domain. Such words cannot be entered in a “universal sentiment lexicon” which is supposed to be a repository of words with polarity invariant across domains. Rather, we need to maintain separate domain specific sentiment lexi...

Triangulation in Pivot-Based Statistical Machine Translation(SMT) is a very effective method for building Machine Translation(MT) systems in case of scarcity of the parallel corpus. Phrase Table Triangulation helps in such a resource constrained setting by inducing new phrase pairs with the help of a pivot. However, it does not explore the possibility of extracting reordering information throug...

Goal creation is an important consideration for an agent that is required to behave autonomously in a real-world domain. This paper describes an agent that is directed, not by a conjunction of top level goals, but by a set of motives. The agent is motivated to create and prioritise different goals at different times as a part of an on-going activity under changing circumstances. Goals can be cr...
