A Controlled Ecological Life Support System (CELSS) is necessary for the long-term manned space exploration. A primary goal of plant research for CELSS is to generate the largest amount of edible biomass possible for the least amount of electrical energy used. A key factor for implementing crop production systems will be the development of energy-efficient lighting approaches. Artificial lighting...
Accurate prediction of crop development stages (phenolgoy) plays an important role in crop production management. Many biochemical actions of plants change with their development stage, therefore, fertilizing the plants at plants' need can increase the fertilizer use efficiency and decrease the waste. For this purpose, this paper presents a prediction model of crop phenology, describing development...
In reverse auction, if a buyer sets quality standard and punishes the suppliers whose product quality doesn't satisfy the quality standard, the low-quality suppliers will quit the bidding process. This will decrease the bidding competition among suppliers and lead to high procurement cost. In order to make bidding competition fierce, buyers often attract some low quality suppliers to enter the auction...
A joint is the structural trace generated by a certain part of crust by the action of tectonic stress in some epoch. The development law and characteristic of it extremely correlate with relevant structure in its area. Joint statistics plays an important role in structural analysis and engineering geological evaluation. Due to extensive data in actual measurement, heavy workload in traditional manual...
There has been increasing challenges in the effective structure of crucial information for effectual information security, personal privacy and data protection. Especially, when in an age of e-commerce, risks and threats from e-commerce transaction have been keeping rising up. Both new ways of cyber information security and security breach, which have affected people's life in some particular aspects,...
Design Principles are standards used to organize and arrange the structural components of Software Engineering design. Methods in which these design principles are applied affect the expressive content and the working process from the start. Design principles help designers build up common consensus about architectural knowledge, help people process with large scale software engineering, help beginners...
According to the knowledge services dynamic composition problems, a knowledge services matching algorithm is proposed based on semantic, which defines the degree of matching as a real number between 0 and 1. The reverse matching strategy starts from the users' output parameters, and according to the matching degree, finds out the sort service list that fits the requirements, finally realizes the dynamic...
