there is undoubtedly general agreement that the efficiency of educational investments should he maximized through the managerial process as far as possible. agricultural extension is one of the crucial tasks in developing agricultural societies calling for considerable consumption of intellectual investment. the management of agricultural extension projects (aeps) however, needs careful pla...

A novel speech bandwidth extension method based on audio watermark is presented in this paper. The time-domain and frequency-domain envelope parameters are extracted from the high-frequency components of speech signal, and then these parameters are embedded in the corresponding narrowband speech bit stream by the modified least significant bit watermark method which uses perception property. At...

essential properties of trust its dynamics context-dependence, calculation, evolution It should be possible to reason about trust across contexts to import trust model into a programming language to include trust model in designing trustworthy computing systems IFIP2008 – p. 5/18 Intension and Extension Intensional logic permits expressions whose value depends on hidden contexts. The real meani...

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...

We describe a variant of the Standard ML programming language which incorporates a facility for the replacement of modular components during program execution. This useful extension of the language builds upon existing compiler technology which permits the separate compilation of modular units of a Standard ML program. Defined naively, this extension would incur performance overheads due to the...

Background: The aim of this study was to investigate the effects of chitosan coatings, oregano essential oil, and their combination on microbial quality of chicken fillet during 12 days in refrigerator temperature. Methods: Oregano oil was extracted by water distillation and then different concentrations of oregano oil (1% and 2%) were used for film preparation. Microbiological tests were carri...

The paper presents the essential features of a new member of the UML language family that supports working with object-oriented frameworks. This UML extension, called UML-F, allows the explicit representation of framework variation points. The paper discusses some of the relevant aspects of UML-F, which is based on standard UML extension mechanisms. A case study shows how it can be used to assi...

We propose a modest conservative extension to ML that allows semi-explicit rst-class poly-morphism while preserving the essential properties of type inference. In our proposal, the introduction of polymorphic types is fully explicit, that is, both introduction points and exact polymorphic types are to be speciied. However, the elimination of polymorphic types is semi-implicit: only elimination ...
