Conventional data envelopment analysis (DEA) models are used to measure efficiency score of production systems when they are considered as black boxes and their internal relationship is ignored. This paper deals with a common special case of network systems which is called multi-stage production system and can be generalized to many organizations. A multi stage production system has some stages...

nigeria represents one of the paradoxes of development in which case the nation is rich but her people are poor. this study examines the rate of poverty among rural households in south western, nigeria. a random multistage sampling was employed for the study. ekiti and osun states were randomly selected from the six states in south-western nigeria. this was followed by random selection of two l...

Signature identification and verification are of great importance in authentication systems. The purpose of this paper is to introduce an experimental contribution in the direction of multi-script off-line signature identification and verification using a novel technique involving off-line English, Hindi (Devnagari) and Bangla (Bengali) signatures. In the first evaluation stage of the proposed ...

The article presents a mathematical model of multi-stage game the process safe control transport object in possible collision situations with other encountered objects, containing description state variables, and constraints, sets permissible strategies. Multi-criteria optimization tasks were formulated form positional matrix games under conditions playing non-cooperative cooperative as well no...

Ongoing SAR missions are already providing a large amount of multi-polarization or polarimetric data and more are expected in the next future from new planned missions. Such a scenario suggests fully automatic procedures for mining and effectively exploiting the information embedded in the polarimetric images, especially when multi-temporality is involved. Processing multi-polarization data for...
