毫米波通信中一种优化的波束搜索算法研究

波束形成技术成为毫米波无线通信的关键技术之一,其中码本搜索算法成为研究重点.IEEE802.15.3c及IEEE802.1 1ad中提出的均是基于遍历搜索的算法,这类算法随着码本数目的增加,搜索时间将变的难以接受.本文提出一种最优扇区数目波束搜索算法,该算法根据波束级码本数目,求出搜索次数最少的扇区数目,并构造相应的扇区码本,然后先在构造的扇区码本上进行搜索,再进行波束搜索.最优扇区数目波束搜索算法利用最优的扇区数目大大减小的波束搜索复杂度,减小的波束搜素所需时间.理论分析和程序仿均证明了最优扇区数目波束搜索算法的在减少搜索次数方面的有效性.

Searching for needles in a haystack: Identifying innovations to prevent MSDs in the construction sector

This study identified innovations that could potentially reduce the risk of MSDs in the construction sector. The action research approach was based on a collaborative model of researchers working with workplace representatives. We searched for innovations being used by construction companies. From a potential database of 125 innovations, the study focused on 20 innovations that varied in their penetration into worksites in the geographical area, represented a variety of trades, and were a cross-section of tools and work organizational processes. It examined the attributes of the innovations, and the barriers to their adoption. The analysis was based on observations of workers, surveys of workers and construction-safety consultants, and company interviews. The study found that innovations were adopted by companies for multiple advantages including productivity and quality, but not necessarily ability to reduce MSD risks, their non-complexity, and cost. The major barriers for adoption were the traditional culture of the construction sector rather than financial ones.     

A multiple criteria decision support on-line system for construction

Technological innovations through changes in the availability of information technology inclusive information systems, neural networks, decision support and expert systems, e-commerce that have been provided by a variety of new services were developed by the construction sector. Most of all construction on-line systems seek to find how to make the most economic decisions. Construction alternatives have to be evaluated not only from the economic position, but also take into consideration qualitative, technical, technological and other characteristics. Based on an analysis of the construction on-line systems the authors of paper developed multiple criteria decision support on-line system for construction.     

A policy mechanism for housing construction activity to achieve social and environmental goals: a case for India

Adequate shelter for all is one of the most pressing challenges faced by developing countries. India is currently facing a shortage of 17.6 million houses. Construction sector represents the most pressing need, viz. shelter. Technologies, which are sustainable environmentally, are another important issue in developing countries, who are on their path to development. Earlier researchers have indicated that construction activity contributes 17% to the carbon dioxide emission in India. In this paper, we have tried to interweave various issues and propose a construction strategy for the Indian housing sector. Affordability of a house and availability of building materials for its construction are the main determinants of access to shelter. This demands efficient use of resources at low cost. This paper analyzes whether it is possible to provide a housing solution at affordable cost by adopting technologies which are less emitting. A policy instrument, energy tax, is designed in this paper that would enforce a switch in technology and promote those technologies, which are well known as least cost but less adopted. An optimization framework developed by Tiwari et al. (1999) and Tiwari (2001) for technology evaluation in house construction based on design codes for India, is used in this paper. Recent government housing policy statements have indicated that an annual supply of two million new houses would be required to meet the current shortage of housing in India. This model is applied to the construction of two million houses. The construction technologies that we evaluate are the commonly used construction technologies as well as the low‐cost techniques. It is asserted that by a proper selection of such techniques and material, the costs and emissions can be reduced substantially and at the same time employment can be generated.     

Web-based concession period analysis system

Public–private partnership (PPP) in infrastructure development is a principal-agent maximization problem that requires a win–win solution for the two partners, the public sector client and the private sector concessionaire. A variety of construction and market risks are involved, which if not properly managed, can significantly affect the economic, financial and social performance of a PPP project. The determination of a suitable concession period is one of the critical issues that have to be carefully examined for effective risk management toward successful PPP project development. This paper introduces an improved concession period determination methodology and develops a web-based concession period analysis system (WCPAS) based on this methodology. Integrating project scheduling tools, financial analysis methods and the Monte Carlo simulation technique, the WCPAS provides a systematic framework and organized modules that provide automatic support for data input and simulation-based analyses for construction cost, construction period, operation period and concession period. The WCPAS facilitates public clients in reasoning and quantifying construction and market risks in order to determine an appropriate concession period and consequently to minimize the potential social, economic and financial problems. A case study is carried out to illustrate the application and usefulness of the WCPAS.     

Learning Bayesian networks using various datasources and applications to financial analysis

 This paper illustrates opportunities of using Bayesian networks in fundamental financial analysis. In it, we will present an application based on construction of a Bayesian network from a database of financial reports collected for the years 1993–97. We will focus on one sector of the Czech economy – engineering – presenting an example that use the constructed Bayesian network in the sector financial analysis. In addition, we will deal with the rating analysis and show how to perform this kind of analysis by means of neural and Bayesian networks. This work was supported by the grant VS96008 of the Ministry of Education of the Czech Republic.

Transient stability of a power system using a non-Luré-type Lyapunov function

A new viewpoint is offered on the construction of a non-Luré-type Lyapunov function for studying the dynamic behaviour of linear systems with a non-linear feedback of the ‘classical’ sector type. The approach makes it possible to show that a particular relation between the parameters defining the Lyapunov function must be satisfied in order to ensure an estimate of the attraction domain closest to the true stability boundary.
