This study was designed to measure technical efficiency and identify its determinants in crop production in Lafia Local government Area of Nasarawa State of Nigeria using a stochastic frontier production model. Double stage random sampling technique was used to select 100 crop farmers from which input-output data were collected based on 2005 cropping season. The results revealed that sixty five...

Providing new production alternatives in the development of economy rural areas Turkey is particular importance. Geographical indication (GI) labelling differentiates a product from its competitors as to region where it originated. The improvement GI strengthens efforts regions maintaining high standards quality regarding health. This paper investigates way implemented by pestil (dried fruit pu...

In computer graphics and engineering many classes of complex objects can be designed with L-systems. We present a concept for enhancing timed and parametric L-systems with physics. This simplifies considerably the physically correct design of certain classes of computer animations or technical objects modelled by production rules. The focus is on structural extensions in timed and parametric L-...

In this paper, we propose a system that tracks a ball stably and accurately and detects the events of the game by using the 3D positional information for automatic soccer video production. We use 3D particle filter with the state vector of nine dimensions in the ball tracking. Since the ball tracking by particle filter is a local search, it is difficult to continue tracking when it fails. Thus,...

Team pursuit track cycling is an elite sport that is part of the Summer Olympics. Teams race against each other on special tracks called velodromes. In this article, we create racing strategies that allow the team to complete the race in as little time as possible. In addition to the traditional minimization of the race times, we consider the amount of energy that the riders have left at the en...
