工程机械主机涨价在即

2010年工程机械市场取得了突破性发展,主要的工程机械产品销量,如挖掘机和装载机都取得了巨大增长,在这种需求旺盛的行业环境下,主机制造商有着涨价的冲动,并通过直接性涨价或间接性涨价把价格转嫁于终端用户。在此,我们先分析一下涨价的主要动力来源。     

A large-scale multi-agent system for navy personnel distribution

In the US Navy, at the end of each sailor's tour of duty, he or she is assigned to a new job. The Navy employs some 280 people, called detailers, full time to effect these new assignments. The intelligent distribution agent (IDA) prototype was designed and built to automate, in a cognitively plausible manner, the job of the human detailers. That model is being redesigned to function as a multi-agent system. This is not a trivial matter due to the fact that there would need to be approximately 350 ‐ 000 individual agents. There are also many issues relating to how the agents interact and how all entities involved, including humans, exercise their autonomy. This paper describes both the IDA prototype and the multi-agent IDA system being created from it. We shall also discuss several of the major issues regarding the design, interaction and autonomy of the various agents involved.     

Effect of Postharvest Holding Conditions on the Quality of Salt-Stock Pickles

Quality changes of green- and salt-stock cucumbers held at 5, 20, and 30°C up to 6 days prior to brining were evaluated. Cucumbers held at 5°C showed firm texture, low respiration rates, minimum weight loss, and good quality stock after fermentation. Increasing postharvest holding temperatures and times prior to brining resulted in loss of firmness, high respiration rates, increased weight loss, and a decrease in salt-stock quality. Salt-stock pickle defects increased dramatically under high temperature long time holding periods due to textural degradation and internal softening. Brining directly after harvest yielded the highest quality salt-stock. Cucumbers held 2 days at 20°C or 6 days at 5°C resulted in good salt-stock quality.
