GPRS车载终端在监控系统中的应用

GPRS车载终端．即把摄像机架设在事故抢险车或路政巡逻车上．摄像机头连接在GPRS网络上．对准事故现场拍摄．通过无线业务GPRS及时将现场图像远程传到监控中心，以便中心管理人员快速了解现场事故状况，做出更好的决策，及时抢救，疏导交通。     

视频检测在隧道意外检测系统的应用

隧道在道路交通中无疑是最危险的路段．一宗比较小的隧道交通意外会在很短时间内引发或演变为一场非常严重的交通事故．酿成不可挽回的悲剧。由于隧道环境的封闭性，交通事故发生后．当事人逃生的机会很小．必须依靠及时有效的外部救援．以减小事故发生的损失．避免事故范围进一步扩大。     

高速公路雾天行车诱导系统研究与探讨

高速公路的鲜明特点表现为高效率和安全性。发达国家统计资料表明．高速公路的交通事故和死亡率只有一般公路的30％和50％。但是．目前我国高速公路的交通事故和死亡率却比一般公路高．自1994年以来我国高等级公路交通事故次数一直占事故总数的30％以上．并呈明显上升趋势。以2003年为例．全年全国公安交通管理部门共受理道路交通事故68万多起．共造成101189人死亡．50.1万多人受伤．直接经济损失34.3亿元人民币，     

让粤通卡和交通安全知识深入人心——广东省“粤通卡高速公路交通安全宣传月”系列活动侧记

近几年．广东省高速公路得到快速发展的同时高速公路交通安全形势依然严峻．群死群伤交通事故还时有发生。今年1至8月．广东共发生道路交通事故46449起、死亡6567人，受伤52946人、直接经济损失1.46亿元。与去年同期相比．除事故起数、受伤人数分别上升983％、9．21％外，死亡人数、直接经济损失分别下降5.97％、10.27％，其中死亡人数减少了417人。广东省共发生一次死亡3人以上特大交通事故108起、死亡439人、受伤371人、直接经济损失619．6万元．与去年同期相比．除直接经济损失上升6．1％外．事故起数、死亡人数、受伤人数分别下降10％、2．44％、9．07％。2004年．在高速公路上发生一次死亡3人以上特大交通事故44宗．死亡171人．分别占全省特大交通事故宗数、死亡人数的25％、27％。     

贵州省高速公路机电系统防雷问题思考

高速公路机电系统主要由供配电、通信、收费、监控等系统组成．由于高速公路所涉地域广．距离长、地形复杂．极易受到雷电的干扰和危害．特别是雷电多发地区的贵州高速公路．每年都会发生很多起机电系统雷击事故．造成整个系统或部分设备损坏．给高速公路运营管理带来极大的不便．而且会带来巨大的直接经济损失和间接经济损失。     

集中供电与中压电能传输新技术在高速公路营运中的应用

高速公路建成投入营运后．电力供给是一个非常重要的课题．供电的安全、可靠和经济是确保高速公路安全运行、提高经济效益的重要环节。电力事故、供电中断将给高速公路营运的收费、监控、通信、通风、照明系统造成管理混乱，严重影响高速公路的正常运行．给国民经济造成重大损失。     

高速公路车辆实时测速联动系统的应用

背景 杭金衢高速公路衢向152K-164K路段开通以来，事故发生率较高，平均每公里死亡人数为0．36，远高于全线平均水平0．2。 分析事敞主要原因是该路段为长直线路段，一方面由于路线线型较好、路面平坦舒适、超速行驶及硬路肩超车的违法行为较多     

基于三层网络模式的隧道交通控制系统

随着我国高速公路建设的快速发展．许多省份的高速公路架构已初具模型。对于高速公路的监控也是从无到有、日趋完善，监控水平有了飞跃的提高。公路隧道，作为高速公路的咽喉地段，一旦出现火灾等突发事故，将造成高速公路的严重交通堵塞．所以对其监控管理的优劣程度将直接影响到整条公路的服务水平。     

高速公路联合监控服务系统

安徽省高速公路管理信息系统经过几年的建设和发展．形成了安徽省高速公路联网收费系统、联合监控服务系统以及运营管理自动化系统等，实现了全省交通管理、收费管理、监控设施管理、通信设施管理、事故处理、供配电管理、救援管理、环境监测等管理的信息化和办公自动化．全面增强安徽省高速公路总公司的综合竞争能力。     

超速监测系统在长大隧道中的应用

宝天高速麦积山隧道全长12 29公里,因隧道里程较长,若通行车辆超速行驶将带来较大的事故安全隐患,宝天高速公路自运营以来,车辆超速行驶一直是造成交通事故发生的重要原因。同时,隧道也是追尾、二次事故、连环事故的多发地段,并且隧道内事故处理难度较大,容易造成长时间堵塞,对高速公路的通行形成压力。为防范事故发生,杜绝车辆在隧道内超速行驶,我们在隧道内采用了超速监测系统来降低事故的发生率。     

品思清东陵

我在想,习惯在古迹前感知沧桑的人,会在历史回声中驻足思远。因为历史的偶然与必然,古人的功过与得失,遗迹的缺失与完整,后人的悬疑与考证……都会在漫漫旅途中隐现。只有通过缕缕哲思的过滤,通过落花人独立的回望,才能思古悟今,让履痕化为精神世界里的一抹丹霞。——行者悟语

Married Women’s Lifestyles in Japan: Disparities Based on the Number of Children

In order to explore the complex mechanisms of married women’s decisions in matters of childbirth, we studied empirically the relations between family size and aspects of lifestyle through a questionnaire survey administered in 2006 to married women living in the city of Suita, Japan, a suburb of Osaka. Lifestyle was taken as a complex of mutual relationships among individual (biographical, psychological) and social (socioeconomic, social support) factors, and our aim was to clarify differences in Japan in lifestyle among married women based on the number of their children. Analysis of 495 respondents showed mothers with only a single child were more self-reliant: they tend to give birth at a late age, enjoy cooperation with their husbands in family finances, be psychologically at ease, and not seek help from others in child rearing. Mothers with three or more children embody more of the traditional role for Japanese women: they tend to give birth at an early age, be reliant on their husbands financially, be less at ease psychologically, and seek others’ help in child rearing. These differences suggest that more focus on psychological, not just economic support in government policy to counteract declining fertility is an important issue for future consideration.     

绿伞：技术先锋造的责任洗衣液

同样达到A级去污标准,绿伞洗衣液使用表面活性剂的浓度仅为12%,而同行至少需要达到25%,这意味着绿伞在能源消耗方面比同行至少节约50%。而先进的抗再沉积技术,使得洗衣过程只需漂水一次就很干净,这又意味着如果北京市每个家庭都使用绿伞洗衣液,那么北京就不用南水北调了!     

Evaluation of a Multi-robot Cafe Based on Service Quality Dimensions

While AI applications are popular in many domains, they should work harmoniously with domain exerts and end users. Furthermore, to develop such harmonious AI applications, we need agile AI platforms for not only developers, but also domain experts. Currently, we have developed PRactical INTElligent aPplicationS (PRINTEPS), which is a user-centric platform to develop integrated intelligent applications. This paper reports on a multi-robot cafe as a practical application of PRINTEPS and evaluates its service quality at a university festival. It is not clear if robotic services are perceived as attractive and/or valuable, and how the concept of robotic services could lead to customer satisfaction. Therefore, the evaluation of the quality of such services is necessary to identify the key factors that could contribute to improving customer satisfaction. The purpose of this research is to identify key factors in improving customer satisfaction in robotic services by evaluating the service quality of the multi-robot cafe. We designed questionnaire items based on SERVQUAL which is one of the service quality evaluation measurement methods and conducted a questionnaire survey at a multi-robot cafe held at a university festival. From the collected data, we modeled and evaluated the relationship between service quality and customer satisfaction to identify key factors in robotic services using a Bayesian network. In addition, the experiment confirms the usefulness of PRINTEPS.

An Advertising Strategy Using Consumption Externality and Forgetting in the Case of Japanese Electronic Books

We construct a two-period model in which a consumer recognizes the existence of goods after advertised by firms, and total sales of the first period affect the utility of each consumer’s purchase in the second period, indicating a consumption externality. Some consumers see advertisements in the first period and remember the product, whereas some forget the product in the second period. We show that the advertising volume changes given the differences in the forgetting rate. In particular, we apply our method to the data on Japan’s electronic books obtained through a conjoint analysis survey to clarify that a better strategy is to sell a product to a small number of people at a low price or to lower the price to a certain level during the early period, and then to sell the product to a specific consumer segment at a higher price after reflecting the externality.     

Who Works at the Interface in Knowledge Spillover Across Organizational Boundaries?

To investigate the characteristics of engineers who act as an interface in transferring knowledge across national boundaries, I conducted an empirical analysis regarding the mobility of engineers in electrical manufacturing firms from Japan to South Korea. Statistical findings from negative binomial regressions show that the experience of working with foreign engineers facilitates knowledge spillover. In addition, the results show that interfirm knowledge transfer is more likely to occur when the engineers of the hiring firm work together with mobile engineers who (1) were focal members at their previous firm, (2) had a good connection with focal members, and (3) are young. This study suggests that engineers from external organizations are effective in knowledge transfer, especially if they are young, mobile engineers who were focal members at their previous firm and had a good connection with a focal member—and can act as an interface in transferring tacit knowledge.
