The digitalization of communication creates novel answers to familiar questions – in the form of digital products. What must be done to define the genres of digital products? What must be done to enable the user to identify the genre? Such questions are not new. Art history refers to and to with the methods of stylistics and iconology, while the role of divides fine ...

HST ACS and NICMOS data are now of sufficient depth and areal coverage to place strong constraints on the formation and evolution of galaxies during the first 1–2 Gyrs of the universe. Of particular interest are galaxies at z 6 since they represent the earliest epoch accessible to current high-efficiency optical instrumentation. To this end, we have been involved in the systematic construction ...

We present aperture-matched PSF-corrected BV izJH photometry and Bayesian photometric redshifts (BPZ) for objects detected in the Hubble Ultra Deep Field (UDF), 8,042 of which are detected at the 10-σ level (e.g., i < 29.01 or z < 28.43). Most of our objects are defined identically to those in the public STScI catalogs, enabling straightforward object-by-object comparison. We have combined dete...

the study was aimed at evaluating the antioxidant activity of hydroalcoholic solution extracts of urtica dioica l. (ud), malva neglecta wallr. (mn) plants and their mixture. in this study, flower (udf), root (udr), seed (uds) and leaf (udl) parts of ud and flower (mnf) and leaf (mnl) parts of mn were used. the antioxidant properties of hydroalcoholic extracts and their mixture were evaluated us...

Recent years have witnessed the revival of organised mass opposition to Apartheid. Fighting in the townships, labour unrest, classroom revolts, rent strikes, consumer boycotts, worker stayaways and guerilla warfare all these have become familiar features of South Africa's political landscape since 1976. From the inception of the United Democratic Front (UDF) in 1983, though, radical black oppos...

Monte Carlo simulations of the field substellar mass function (MF) are presented, based on the latest brown dwarf evolutionary models from Burrows et al. (1997) and Baraffe et al. (2003). Starting from various representations of the MF below 0.1 M⊙ and the stellar birth rate, luminosity functions (LFs) and Teff distributions are produced for comparison with observed samples. These distributions...

A fine-grained user-aware access control to user profile data is the key requirement for sharing user profiles among applications, and hence improving the effort of these systems massively. Policy languages like Protune can handle access restrictions very well but are too complicated to be used by non-experts. In this paper, we identify policy templates and embed them into a user interface that...

the rational cubic function with three parameters has been extended to rational bi-cubic function to visualize the shape of regular convex surface data. the rational bi-cubic function involves six parameters in each rectangular patch. data dependent constraints are derived on four of these parameters to visualize the shape of convex surface data while other two are free to refine the shape of s...
