the study investigated challenges to soil erosion control measures among farmers in anambra state, nigeria. purposive, multistage and random sampling techniques were employed in selecting a sample size of two hundred and forty (240) respondents. structured interview schedule was used for data collection. frequency counts, percentage, mean scores and factor analysis were used for data analysis. ...

Stochastic comparison results for replacement policies are shown in this paper using formalism of point processes theory. At each failure moment a repair is allowed performed with a random degree of repair including as special cases perfect, minimal, imperfect repair models. Results for such repairable systems with schemes of planned replacements are also shown. The results are obtained by coup...

Cross-site scripting (XSS) vulnerabilities are among the most prevailing problems on the web. Among the practically deployed countermeasures is a``defense-in-depth'' Content Security Policy (CSP) to mitigate the effects of XSS attacks. However, the adoption of CSP has been frustratingly slow. This paper focuses on a particular roadblock for wider adoption of CSP: its interplay with browser exte...

Household food security remains a challenge in South Africa. The national government instituted the Integrated Food Security Strategy (IFSS) programme which identifies household agricultural production as an important element of improving household-level food security. Agricultural extension is well positioned to help achieve this aim, but its current contribution is unknown. This study identif...

The study investigated the effect of Community-Based Paid Extension (CPE) on vulnerability reduction of smallholder dairy farmers. Randomly sampled 255 farmers were interviewed together with 15 key informants’ interview. Both statistical analysis and thematic approach were employed to achieve triangulation. In about 68 % of cases, CPE reduced vulnerability to a degree experienced as ‘moderate’,...

A new set of boundary-handling algorithms has been developed for discrete wavelet transforms in the ISO/IEC JPEG-2000 Still Image Coding Standard. Two polyphase component extrapolation policies are specified: a constant extension policy and a symmetric extension policy. Neither policy requires any computations to generate the extrapolation. The constant extension policy is a low-complexity opti...
