As the use of information and communication technologies (ICT) is embraced in Uganda, determinants of awareness of ICT based projects remain unknown. The intensity of use of mobile phones among smallholder farmers in the areas where such projects operate is unclear. To address this knowledge gap, 346 smallholder farmers in two ICT project sites in Mayuge and Apac districts were subjected to eco...

Sets of unit vectors in N-dimensional Eucl idean vectorspace whose constituent vectors are separated one from another by atleast a fixed distance d, prescr ibed once for all and independent of N,are of interest in theory and practice; they have fondly been called“porcupine codes.” Although an elegant constructive proof of Gilbertshows that the number of vectors in a porcupin...

The VESPRA system is designed f o r the processing of chains of (not connected u t te rances o f ) wordforms. These s t r i n g s of wordforms correspond to sentences except t ha t they are not r e a l i s e d in connected speech. VESPRA means: Verarbe i tung und Erkennung gesprochener Sprache (process ing and r e c o g n i t i o n of speech). VESPRA w i l l be used to c o n t r o l d i f f e r...

A South African non-profit organisation, FunDza, launched a programme that delivers reading material via mobile phones. Computer log files of user activity over an eight-month period were analysed (N = 9,212,716), which showed that relatively large numbers of readers made use of the material (N = 65,533), and read a substantial amount of the material. We found evidence of positive shifts in rea...

Mobile phones are increasingly popular tools not only for daily use but also for research purposes. The authors systematically searched related literature using mobile phones as a tool for data collection and found 171 publications consisting of review, empirical, methodological, and theoretical studies in various disciplines such as medicine, engineering, and education. After reviewing contrib...

Interaction, such as being able to ask questions, is an important part in lectures. Both educators and students can benefit from software support in very large lectures. As a cost-effective and widely usable solution, we have investigated interaction based on the mobile phones owned by most students. After presenting design criteria, we discuss a concrete prototype for mobile phone-based intera...
