基于实训基地中职汽修专业教学模式构建探究

职业院校是培养专业技术人才的摇篮。而汽修专业是一门实践性很强的学科,要切实提高学生的汽车维修技术,大量的实践教学必不可少,这将有利于提高学生的专业素养以及实操能力,为学生夯实就业基础。因此,中职汽修专业实训基地的建设极为重要。尤其是如今人们生活水平大步提升,汽车已在我国获得普及应用。近年来私家车数量陡增,而汽修专业人才呈现较大缺口,这是中职汽修专业人才发展的良好契机,也是对汽修专业教学的一种挑战。如何培养出一批专业能力强、素养高的汽修人才,这是中职院校亟待解决的重要教育课题。

香港船王的航运低谷

香港拥有世界上最庞大的独立商船队，在上世纪八十年代的世界航运危机中，香港众船王采取了不同的策略，从而导致了截然不同的企业发展轨迹。今天，当世界金融危机演变成经济危机，进而侵袭航运市场时，航运业再一次面临着非常严峻的考验，寒冬中如何求得生存发展，回眸香港船王们当年的决策得失或许对我们今天有着积极的现实意义。     

莫让江水难畅流——我国航道现状及发展透视

我国是一个水运资源丰富的国家,海域广阔,江河湖泊纵横.一般河流水量充沛,多数河流常年不冻.我国内河航道主要分布在长江水系、珠江水系、黑龙江水系、黄河水系、淮河水系、钱塘江水系及海河、闽江和东南沿海各个独自入海的水系.这些水系中的河流,上游发源于高山峡谷,下游流经平原沃野,构成我国内河航运中的主要航道.据统计,我国拥有大小江河5800多条,天然湖泊900多个.河流总长43万多公里,流域面积在1万平方公里的就有80多条,其中航道通航里程为11.65万公里.显然,我国具有得天独厚的发展水路运输的先决条件.那么我国航道的发展状况究竟如何呢?……

Dynamic demand estimation and microscopic traffic simulation of a university campus transportation network

Abstract

This article documents the authors' experience with the modeling, simulation, and analysis of a university transportation system, using the TRansportation ANalysis and SIMulation System (TRANSIMS). The processes of data preparation and network coding are described, followed by the algorithm developed to estimate the dynamic 24-hour demand, which includes a procedure for estimating the ‘desirability’ of the different parking lots from readily available data. The dynamic demand estimation algorithm is validated by comparing estimated and observed parking lot occupancies, where it is shown that the algorithm is capable of replicating observed results. Finally, an example is included to demonstrate how the developed model can be used in campus transportation planning. Besides serving as a first case study for using TRANSIMS to model a university campus, the study's contributions include the development of a procedure for parking lot desirability ranking and a practical procedure for estimating dynamic demand on university campuses.

基于PSTN和IP宽带网的远程监控系统

为提高远程视频监控系统扩展性和灵活性,适应网络带宽的变化,提出了基于PSTN和IP宽带网的监控系统结构模型。使用位率控制精度较高的编码器以适应PSTN(公众交换网的缩写)这种低带宽网络。并采用带宽自适应的策略和方法,实现对网络状况的动态自适应。该系统的编码器采用纯软件实现,能动态地适应网络状况,并能最大限度地利用网络资源。     

Flexible feeder transit route design to enhance service accessibility in urban area

To improve the accessibility of transit system in urban areas, this paper presents a flexible feeder transit routing model that can serve irregular‐shaped networks. By integrating the cost efficiency of fixed‐route transit system and the flexibility of demand responsive transit system, the proposed model is capable of letting operating feeder busses temporarily deviate from their current route so as to serve the reported demand locations. With an objective of minimizing total bus travel time, a new operational mode is then proposed to allow busses to serve passengers on both street sides. In addition, when multiple feeder busses are operating in the target service area, the proposed model can provide an optimal plan to locate the nearest one to response to the demands. A three‐stage solution algorithm is also developed to yield meta‐optimal solutions to the problem in a reasonable amount of time by transforming the problem into a traveling salesman problem. Numerical studies have demonstrated the effectiveness of the proposed model as well as the heuristic solution approach. Copyright © 2015 John Wiley & Sons, Ltd.
