ARTICLE INFO QR Code is generated with insertion of a color image into it with minimal probability of detection errors. With standard decoding applications these insertions of vital information using QR code into color codes are possible. This insertion takes benefits of the support of QR readers against interruption of image luminance moreover, the vital information in QR code bits are transfo...

Quinone reductase (QR) is a phase II detoxification enzyme that plays an important role in detoxifying quinones and may help maintain the antioxidant function of the cell. We have previously observed that QR is up-regulated by anti-oestrogens, but not oestrogen, in breast cancer cells via ERbeta (oestrogen receptor beta) transactivation. Such QR induction appears to protect breast cells against...

The QR algorithm is one of the most widely used algorithms for calculating the eigenvalues of matrices. The multishift QR algorithm with multiplicity m is a version that eeects m iterations of the QR algorithm at a time. It is known that roundoo errors cause the multishift QR algorithm to perform poorly when m is large. In this paper the mechanism by which the shifts are transmitted through the...

This paper describes a new model for presenting local information based on the network proximity. We present a novelty mobile mashup which combines Wi-Fi proximity measurements with QR-codes. Our mobile mashup automatically adds context information the content presented by QR-codes. It simplifies the deployment schemes and allows to use unified presentation for all data points, for example. Thi...

In the year 2000 the dominant method for solving matrix eigen-value problems is still the QR algorithm. This paper discusses the family of GR algorithms, with emphasis on the QR algorithm. Included are historical remarks, an outline of what GR algorithms are and why they work, and descriptions of the latest, highly parallelizable, versions of the QR algorithm. Now that we know how to paralleliz...

The QR algorithm is still one of the most important methods for computing eigenvalues and eigenvectors of matrices. Most discussions of the QR algorithm begin with a very basic version and move by steps toward the versions of the algorithm that are actually used. This paper outlines a pedagogical path that leads directly to the implicit multishift QR algorithms that are used in practice, bypass...

Nowadays, mobile devices and applications offer new possibilities to learn anytime and anywhere. These technologies caused a disruption in traditional learning, opening up a new range of opportunities for learning at the workplace. Quick Response (QR) codes are one example of technology popularized with the adoption of mobile devices. When attached to an object or location, QR codes add a digit...

This paper introduces the concept of QR codes, an automatic method to hide information using QR codes and to embed QR codes into colour images with bounded probability of detection error.The embedding methods are designed to be compatible with standard decoding applications and can be applied to any colour or gray scale image with full area coverage. The embedding method consists of two compone...
