Ensuring the security and privacy of information in mobile health-care communication systems
(Academy of Science of South Africa, 2011)
The sensitivity of health-care information and its accessibility via the Internet and mobile technology systems is a cause for concern in these modern times. The privacy, integrity and confidentiality of a patient’s data ...
ANCAEE: A novel clustering algorithm for energy efficiency in wireless sensor networks
(Scientific Research Publishing, 2011)
One of the major constraints of wireless sensor networks is limited energy available to sensor nodes because of the small size of the batteries they use as source of power. Clustering is one of the routing techniques that ...
Time series photometry of the nearby brown dwarf DENIS-P J0041353-562112
(Oxford University Press, 2011)
DENIS-P J0041353−562112 is a brown dwarf, with a spectral type of M7.5, which may be
younger than 20 Myr. On the basis of its Hα emission-line asymmetry, it has been suggested
that the object is accreting material. If ...
UBV(RI)C photometry of transiting planet hosting stars
(Oxford University Press, 2011)
We present new UBV(RI)C photometry of 22 stars that host transiting planets, 19 of which
were discovered by the Wide Angle Search for Planets (WASP) survey. We use these data
together with Two Micron All Sky Survey (2MASS) ...
Deaf telephony: community-based co-design (case study)
(Wiley, 2011)
The process of community-based co-design is one that explores various solution configurations in a multi-dimensional design space whose axes are the different dimensions of requirements and the various dimensions of designer ...
2-Arylnaphthoquinone analogues: Potential anti-TB and pro-apoptotic agents
(Green, I. R. et al. (2011). 2-Arylnaphthoquinone analogues: Potential anti-TB and pro-apoptotic agents. ARKIVOC, (x), 192-212. https://doi.org/10.3998/ark.5550190.0012.a16, 2011)
A useful library of substituted 2-arylnaphthoquinones prepared by reaction between the
corresponding bromonaphthoquinones and arylboronic acids via Suzuki-Miyaura protocols has
been established. Conversion of some of the ...
The orbital periods of aa dor and ny vir
(Oxford University Press, 2011)
New timings of eclipses made between 2000 and 2010 are presented for two binary systems
with hot subdwarf primary stars. In the case of AA Dor, an sdOB star with a very cool
secondary, the period is found to be constant ...
Human coronavirus NL63: A clinically important virus?
(Future Science Group, 2011)
Respiratory tract infection is a leading cause of morbidity and mortality worldwide, especially among young children. Human coronaviruses (HCoVs) have only recently been shown to cause both lower and upper respiratory tract ...
Proteomic analysis of grape berry cell cultures reveals that developmentally regulated ripening related processes can be studied using cultured cells
(Public Library of Science, 2011)
This work describes a proteomics profiling method, optimized and applied to berry cell suspensions to evaluate organ-specific cultures as a platform to study grape berry ripening. Variations in berry ripening within a ...
Clustering of HI galaxies in the HI parkes all sky survey and arecibo legacy fast alfa survey
(Oxford University Press, 2011)
We investigate the clustering of H I-selected galaxies in the Arecibo Legacy Fast ALFA
Survey (ALFALFA) and compare results with those obtained for the H I Parkes All Sky
Survey (HIPASS). Measurements of the angular ...
