The DAISY system is currently used as the alternative reading format for print-disabled students in Norway. DAISY is denoted by many as universally designed. This is an important claim, ensuring suited learning opportunities for all students. Thus, to be able to determine this aspect of DAISY is important – as is the case for many information systems. However, methods for evaluating whether a s...

Since graphs are ubiquitous representations of data that are used in many applications, creating graph layouts is an important problem. These graph layouts are usefully discussed in terms of aesthetics that originated from mathematical concepts. In contrast, we explore the use of alternative aesthetics to inspire the visualization of graphs. We present Daisy Visualization, for which we have des...

Our aim in this note is to make some conjectures about extremal densities of daisy-free families, where a ‘daisy’ is a certain hypergraph. These questions turn out to be related to some Turán problems in the hypercube, but they are also natural in their own right. We start by giving the daisy conjectures, and some related problems, and shall then go on to describe the connection with vertex-Tur...

The Cognitive Daisy is an innovative assessment system created to provide healthcare staff with an instant snapshot of the cognitive status of older adults in residential care. The Cognitive Daisy comprises a flower head consisting of 15 colour coded petals depicting information about: visual-spatial perception, comprehension, communication, memory and attention. This study confirmed the practi...

In this paper, it is proposed to improve Daisy Descriptor based face recognition using a novel One-Bit Transform (1BT) based pre-registration approach. The 1BT based preregistration procedure is fast and has low computational complexity. It is shown that the face recognition accuracy is improved with the proposed approach. The proposed approach can facilitate highly accurate face recognition us...

In plant-pollinator interactions, pollinating insects provide reproductive service to plants and receive food rewards. Flowers advertise the presence of nectar or pollen through various characteristics, including visual displays. In daisies (Chrysanthemum frutescens), the center of the inflorescence appears as a UV-absorbing bull’s-eye that attracts pollinators, for example honeybees. Thomisus ...

“Daisy, Daisy, give me your answer, do!” [10] For any positive integer n, the units of Zn are those elements of Zn \ {0} that are coprime with n. The number of units in Zn is given by Euler’s totient function φ(n). If n is odd, a daisy chain for the units of Zn is obtained by arranging the units of Zn on a circle in some order [a1, a2, . . . , aφ(n)] such that the set of differences bi = ai+1 −...
