文章简要介绍了《原油油船货油舱保护涂层性能标准》(以下简称"货油舱PSPC"),通过与压载舱保护涂层性能标准(以下简称"压载舱PSPC")的比较,分析了货油舱PSPC与压载舱PSPC相异的技术条款对船舶建造的影响,研究了大连中远川崎船舶工程有限公司满足货油舱PSPC实施难点的对应措施。     

船舶货舱温度遥测系统的设计

近年来,我国远洋和船舶轮机自动化的水平有了较快的提高,但货舱温度监控却始终是一个薄弱环节,本文设计及制作了一个基于DS18B20的温度实时无线遥测报告系统,该系统采用单工单收单发模式,由于采用了DF无线数据传输方式和通过串口与PC通信,可方便容易地检测并记录远处0至＋100℃范围（范围可变）的温度。     

Evaluating the operational performance of airside and landside at Chinese airports with novel inputs

ABSTRACT

This paper evaluates the operational performance of airside and landside at Chinese airports with two novel inputs. Furthermore, the airport landside operation is decomposed into passenger-terminal operations and cargo-warehouse operations. One novel input is the capability of the runway system which is introduced into airside performance evaluation. The other novel input is cargo warehousing which is introduced into landside performance evaluation. To address multiple optimal solutions when estimating Returns to Scale in Data Envelopment Analysis, we adopted the Zhu and Shen method. This empirical study shows that neither the number of runways nor total runway length is a genuine index of runway system capability in the evaluation of airside performance. Only four airports achieved full efficiency in all eight measures while eight airports did not achieve any full efficiency. In addition, one airport did not perform well in the benchmark analysis.     

Analysis of factors affecting the choice of route of pedestrians

Pedestrians as compared to vehicular traffic enjoy a high degree freedom of movement even in heavily congested areas. Consequently, there are more alternative links available to pedestrians between a given origin‐destination (O‐D) pair. This paper describes a study done by the University of Calgary to evaluate the factors affecting the choice of route on intra‐CBD trips or trips within the Central Business District (CBD).

An origin destination survey conducted in downtown Calgary, Alberta enabled the identification of the most significant factors influencing the choice. These factors were analyzed in relation to the physical characteristics of the location, personal characteristics of the trip maker and the type of the trip.

It appears that most people chose the shortest link and factors such as the level of congestion, safety or visual attractions were only secondary. This suggests that the length should be made a major consideration when planning and designing pedestrian links.     

空调进风口前端水管理及相应进风阻力关系

为了使空调前端进风口设计的更加合理,文章在确定进气格栅支撑板上排水口的位置及大小的情况下,通过CFD模拟前端水管理及前端进风口的阻力,并通过更改进气格栅的面积、开孔位置及增加挡板高度等方法,来满足水管理和进气阻力的要求。得出水管理与进气阻力之间关系：前端水管理设计比较理想,会牺牲前端进风阻力,使前端进风阻力增大;相反,为了使前端进风阻力更加合理,减小前端进风阻力,会牺牲前端水管理的性能。二者相互影响,相互制约。

Multioutput analysis of cargo handling firms: An application to a Spanish port

Cargo handling in ports is a multioutput activity, as freight can arrive in many forms such as containers, bulk, rolling stock, or non-containerised general cargo. In this paper, the operation of cargo handling firms in a Spanish port is analysed through the estimation of a multioutput cost model that uses monthly data on three representative firms located at the Las Palmas port. This permits the calculation of product specific marginal costs, economies of scale (general and by firm) and economies of scope, which help identifying optimal pricing policies and the potential cost advantages of increasing production.
