This study compares the effectiveness of internet advertisements (pop-ups), print advertisements (posters) and radio advertisements for an airline ticket and for a weekend stay at a hotel. The advertisement copies were developed specifically for this study by a professional agency. Advertisements were developed to utilise specific medium characteristics, and the control of advertisement content...

A wave impinging on a Kerr black hole can be amplified as it scatters off the hole if certain conditions are satisfied giving rise to superradiant scattering. By placing a mirror around the black hole one can make the system unstable. This is the black hole bomb of Press and Teukolsky. We investigate in detail this process and compute the growing timescales and oscillation frequencies as a func...

Computationally-enriched crafts are activities that blend the advantages of computational media with the affective, social, and cognitive affordances of children's crafts. In this paper, we describe a design application, Popup Workshop, whose purpose is to introduce children to the craft (and engineering discipline) of pop-up design in paper. We describe the fundamental ideas behind computation...

Notification displays have the potential to make smartphone notifications easier to manage when a user is committed to a primary task. The authors investigate the impact of negotiating notifications with six notification displays on a typing task. The results from their lab experiment with 30 participants show that desktop pop-ups were preferred significantly most, the display choice that requi...

This paper presents politeness as a key social requirement for computer human interaction (CHI). Politeness is defined, in information terms, as offering the locus of control of a social interaction to another party. Software that creates pop-up windows is not illegal, but is impolite, as it preempts user choice. It is proposed that impolite software drives users away, while polite software att...

A new wet/dry sensor was developed by the satellite-based pop-up archival transmitting (PAT) tag manufacturer to determine the wet and dry status of a tag, designed to indicate whether or not to initiate uplink transmissions to overhead satellites to extend tag battery life. We discovered that the wet/dry sensor can also be used to measure the salinity of coastal waters after we recovered a PAT...

This paper describes the construction of a layered scene model, based on a single hazy image that has sufficient depth variation. A depth map and radiance image are estimated by standard dehazing methods. The radiance image is then segmented into a small number of clusters, and a corresponding scene plane is estimated for each. This provides the basic structure of a layered scene model, without...

Price Discrimination in the Concert Industry Concert tickets can either be sold at a single price or at different prices to reflect the various levels of seating categories available. Here we consider how two product characteristics (the artist’s age and venue capacity) influence the likelihood that pop music concert tickets will be sold at different prices. We argue that valuation heterogeneit...

We (numerically) construct new static, asymptotically AdS solutions where the conformal infinity is the product of time and S2 × S1. There always exist a family of solutions in which the S1 is not contractible and, for small S1, there are two additional families of solutions in which the S1 smoothly pinches off. This shows that (when fermions are antiperiodic around the S1) there is a quantum p...

Information on oceanic migrations and spawning areas of tropical Pacific freshwater eels (genus Anguilla) is very limited. Lake Letas and its single outflowing river, Mbe Solomul on Gaua Island, Vanuatu, were surveyed for large migrating individuals. Twenty-four Anguilla marmorata (87 to 142 cm), 39 A. megastoma (50 to 131 cm), and 3 A. obscura (119 to 126 cm) were caught. Seven individuals wer...
