A new data base computer package for plant breeders

Summary A computer data base package, specifically designed to be used to store data collected from a plant breeding programme is described. The package will do many of the routine clerical operations involved in plant breeding, such as producing plot labels, field plans, genotype lists and data tabulations. It also has several statistical analysis routines, and routines which allow the user to examine and manipulate data. The package is user friendly since it was designed to be operated by plant breeders rather than computing specialists. Although it was written to handle data collected from a plant breeding programme, the package is flexible and could be used for a number of different applications.

Numerical Modeling to Study the Fate of Nitrogen in Cropping Systems and Best Management Case Studies

Summary

Nitrogen (N) availability for crop uptake is dependent on various factors that influence the transformation of N sources and transport of N forms in soils. The fate and transport of N is site specific. Therefore evaluation of N dynamics under each condition is neither practical nor feasible. Simulation models which are adequately calibrated and tested can be used to estimate the fate and transport of N as well as crop responses under different production systems. These evaluations provide some guidelines as how to manage N and water efficiently to maximize the N uptake efficiency and minimize the losses. Thus, they contribute to the development of N and water best management practices. In this chapter, we discuss recent information on experimentally measuring the water and nutrient transport in soils as well as performing estimations using simulation models. The development and application of different simulation models for different production systems have been summarized. Some case studies on nitrogen and water best management practices are also discussed.

Design of Simulation System for Logistics in Steel-making Process

A simulation system for logistics in steel-making process has been developed by analyzing the state of logistics in steel plant, integrating the approach of coloured Petri nets with time and queuing network and using object-oriented methodology. The software functions for building-up simulation model, executing simulation, managing simulations, playing demo, analyzing statistics and online help. The objectives and principles of the simulation software have schematically been introduced. At last, the software is visually validated with measured input data of primary logistics in Vanadium-extracting, Steel-making Plant of Panzhihua Iron and Steel Corporation. A Gantt diagram and statistics of simulation case are included in simulation results and can be used to assist decision-making for scheduling in steel-making process.
