有线电视收视记录器的系统模型和改进

从事收视率调查的从业者都期望能实时掌握最新的收视行为,并由收视率调查信息的反馈来了解或证明该节目或广告的成功与否,作为节目或广告从业人员参考或修正的依据.收视记录器是提供媒体从业人员对收视率调查的测量仪器,它产生准确和客观的收视行为数据.在众多收视率调查方式中,收视行为记录器(People Meter)的测量方式是最客观的量化方式,因此,一部良好的收视行为记录器实时地从收视样本户中取得准确客观的收视行为数据是相当重要的.

Fall and Rise of the Largest Construction Manager-at-Risk Transportation Construction Project Ever

All parties agree that the Miami Intermodal Center (MIC) construction project got off to a bad start, but why did this project—so anxiously anticipated, so badly needed, and kicked off with such fanfare—seem destined for so long to be remembered as a high-priced failure? After the bad start, why did the MIC project seem to struggle so for almost four years before—seemingly all at once—finding direction? What were the factors behind the bad start? What were the factors behind the lack of progress once the project started? What were the factors behind a remarkable turnaround? This paper answers these questions and more. The product of four years of research and data gathering, this paper should be of use to researchers and practitioners. It uses dozens of interviews with project planners, Florida Department of Transportation administrators, and construction personnel, as well as pertinent data to tell the story of the first 5 years of the construction of this groundbreaking world-class multimodal facility that is estimated to take 15–20 years to construct and cost approximately $2.5 billion.     

Inventing the Rural: A Brief History of Modern Architecture in the Countryside

The rural has long occupied a valuable, if under-theorised position in modern architectural history. Here, Cole Roskam , Assistant Professor of Architectural History at the University of Hong Kong, highlights key moments in this history and, in doing so, illuminates a central paradox at the heart of architecture's various turns to the countryside; namely, can architects maintain the physical and social integrity of the rural when they are themselves a fundamental vector of its changing character?     

保障性住房户外公共空间利用研究——以厦门市集美滨水小区为例

随着社会的发展,人们对居住环境的要求也有所提高。关注点已从过去的室内环境逐步转移到户外公共空间与环境,而这正是目前保障性住房设计所忽视的环节所在。本文以厦门市集美滨水小区户外公共空间为研究对象,通过发现问题并分析,借鉴国外的相关建设经验,针对现状的不足提出若干改进意见,旨在探讨如何创造一个自然、和谐、安全、健康的保障性住区户外环境。     

“生态校园、诗意校园、山地校园”——杭州科技职业技术学校总体规划设计

文章介绍了杭州职业技术学校总体规划设计理念:通过萃取构成基地的三个主要景观元素——丘陵、河流(冲沟)、水塘,组织和利用丘陵、建筑与水体的互相关系来取得生态化、诗意般的山地校园空间;通过建筑单体设计实现室内空间到室外公共活动空间的过渡,通过校园共享空间的组织,着意创造层次丰富、形式多样的空间形态满足现代化校园开放性的要求。

Simulation of fire scenarios due to different vehicle types with and without traffic in a bi-directional road tunnel

This paper presents findings obtained by CFD modelling for simulating the effects of fire due to different vehicle types in a bi-directional road tunnel. Four different burning vehicles placed in the centre of the driving lane at tunnel middle length were considered. Peaks of the heat release rate (HRR) of: 8, 30, 50, and 100 MW were simulated for the two cars, the bus, the heavy goods vehicle (HGV), and the petrol tanker, respectively. The fire effects on tunnel structure and on environmental conditions along people evacuation path were especially evaluated. The effects of the traffic jam, in contrast with the isolated vehicles, on temperatures, radiant heat flux, visibility distance, and toxic gases concentrations, were also investigated. The worst scenario was identified to be that pertaining to the petrol tanker and more critical conditions were also found when the tunnel was full of vehicles. The maximum gas temperatures reached in the presence of traffic at the side wall (and at the tunnel ceiling reported in brackets) were found to be: 360 °C (170 °C) for the two cars; 740 °C (465 °C) for the bus; 835 °C (735 °C) for the HGV and 1305 °C (1145 °C) for the petrol tanker, respectively. The presence of the traffic, in contrast with the isolated vehicle, involved an increase in the maximum temperatures equal to 16–17% for the two cars, and contained in the range 12–29% with percentages increasing starting from the tanker, to the HGV and to the bus. In other words when the maximum temperatures produced by the isolated vehicle are very high (e.g. for the tanker), the presence of the traffic had a minor effect. With reference to environmental conditions along the evacuation path, the results showed that in the case of petrol tanker fire the emergency ventilation ensures a tenable level of temperature, radiant heat flux, and toxic gases concentrations up to 5 min from the fire starting. This time increases up to 6.5 min for the HGV and 8 min for the bus. This means that the tunnel users in order to be safe in all scenarios should leave the tunnel within 5 min after the fire starting. Toxic gases concentrations, however, were found to be below the limit values in all cases and also in the presence of traffic. In the light of the aforementioned results, tunnel occupants should be promptly informed of the fire risk and guided to the exit portals. This might be done by equipping the tunnel with illuminated emergency signs located along the tunnel length and by installing traffic lights before the entrances so that the tunnel can be closed in case of emergency. By activating the traffic lights at the portals and the emergency signs (more especially those at the ceiling) at the same time as the emergency ventilation is activated, safer conditions for the people evacuation are expected.
