Scenarios have been advocated as a means of improving requirements engineering yet few methods or tools exist to support scenario based RE. The paper reports a method and software assistant tool for scenario-based RE that integrates with use case approaches to object oriented development. The method and operation of the tool are illustrated with a financial system case study. Scenarios are used...

To decrease the impact of uncertainty disturbance such as sideslip from field environment on path tracking control accuracy an unmanned rice transplanter, a method for autonomous transplanter based adaptive sliding mode variable structure was proposed. A radial basis function (RBF) neural network, which can precisely approximate arbitrary nonlinear function, used parameter auto-tuning on-line. ...

Cities have been increasingly involved in the development of food policies, becoming key points achieving security and fostering transition to sustainable agri-food systems. The aim this paper is identify citizens’ profiles by performing segmentation profiling according their socio-economic variables perception factors affecting security.

FWL prevention recently gained much attention priority among governments international organizations as major means achieve global security sustainability; led very ambitious UN goal SDG 12.3, which aims halve lo...

The article summarizes and systematizes the causes consequences of food loss waste. uncontrolled accumulation inefficient management waste is a serious problem security in many countries. Moreover, world annually loses or wastes about third produced while natural resources are inefficiently used. A significant number definitions terms field cause international inconsistency systems. So, systema...

This study determined the effect of Vachellia karroo leaf meal (VKLM) in diets on feed intake (FI), digestibility, conversion ratio (FCR), body weight gain (BWG), final live (FLW) and meat quality parameters male Ross 308 broiler chickens fed from 22 to 42 days. One hundred sixty 22-day-old were assigned four treatments with replicates 10 chickens. VKLM inclusion levels at 0, 0.5, 1.0 1.5 g/kg ...
