In order to apply this algorithm to maneuvering targets tracking ,a tracking signal is performed on-line to determine what kind of TOSm will be in effect to track a target with different dynamics. An effective multiple model least squares filtering and forecasting method dadpted to real tracking of a maneuvering target is formulated. The algorithm is computationally more effcient than Kalman filter and the percentage improvement from simulations show both of them are considerably alike to some extent.展开更多

We bring some doubt to the use of “risk” and “uncertainty” interchangeably in project management and deem their scope, methods, responses, monitoring and controlling should be different too. Illustrations are given covering terminology, description, and treatment from different perspectives of uncertainty management and risk management. Furthermore, the paper retains that project risk management (PRM) processes might be modified to facilitate an uncertainty management perspective, and we support that project uncertainty management (PUM) can enlarge its contribution to improving project management performance, which will result in a significant change in emphasis compared with most risk management.展开更多

The first is qualitative, highlighting the lack of dialogue between the standard-project architecture, the guidelines recommended by the COEDI （Coordenagao Geral de Educao Infantil （General Coordination of Early Childhood Education）） of the Ministry of Education, socio-technical and cultural-environmental context and pedagogy. The second, more quantitative, addresses the problems generated by dissociation between the constructive solutions and the bioclimatic demands of different insertion contexts of architectural design in the Brazilian Bioclimatic Zone 2. Initially planned to use a conventional building system, it was transposed to the Wall System, developed by MVC Componentes Pl^tsticos Ltda. The simulation evaluates and compares the level of thermal comfort of the building with two envelope systems. The study reports the analysis of the thermal comfort of a Type C unit, based on thermodynamic simulation, through the software Design Builder （version 4.2.0.054）. The analysis of the building simulation results was based on the adaptive comfort model ASHRAE 55/2010. Later, three optimization measures of the thermal comfort level of the building were tested, based on thermal insulation and absorptance coverage, in addition to sun protection system design for the window frames. Preliminary results for the level of comfort of long permanence environments indicate a tow level of thermal comfort, the 50% in MVC system and around 60% in the conventional system, and also that the greater discomfort comes from the heat. Based on performance optimization measures of building, the MVC system reached 66.4% of thermal comfort compared to 62% in the conventional system. The results show the importance of adapting the standard project to the local climatic context.展开更多

The completion of legal harmonization brought in new emission standards and thresholds, and this was followed by EU-assisted projects to build and reconstruct wastewater treatment plants. The utilization of sludge after it leaves the wastewater treatment plant is now a solely private-sector operation. There are new political priorities： increasing state involvement, buying out of major--formerly privatized--service providers, reintegration of isolated service providers, legally-imposed reduction of public utility charges. As a result, a demand has arisen for a greater central, i.e. government role in sludge utilization.展开更多

There is problem of complexity environment to understand real economic growth. Companies and government can affect economic. There is a need to make standards to control steps of economic growth as result to accounting gaps, economic gaps, and financial analysis gaps. Standards must face negative affection of speculation, government involving in economic, developing tool. Evaluating must be built up to real market price and also standards must build trust to support developing. Searcher recommended linking economic growth with real growth of producing and ways to get real market price to evaluate company assets, liabilities, and net profit after tax for all users as factors show growth in company to growth economic units which are successful by applying creative projects.展开更多

At this time, there is no standard method to analyze a delay claim. This paper first introduced a fictional case study that has most types of delay and acceleration events that might be faced on a real project. The case study is applied to all current techniques of delay claims that have been identified from previous studies. The comparison uses the delay claim issues as criteria to evaluate all the delay claim techniques from the case study results. The case study result and discussion demonstrate that the Day-by-Day technique satisfies all the desired criteria while other techniques lack some.展开更多

The original COCOMO model is one of the most widely practiced and popular among the software development community because of its flexible usage. It is a suite of models i.e., COnstructive Cost MOdel I and COnstructive Cost MOdel II. in this paper, we are evaluating the both models, to find out the level of efficiency they present and how they can be tailored to the needs of modem software development projects. We are applying COCOMO models on a case study of an e-commerce application that is built using Hyper Text Markup Language （HTML） and JavaScript. We will also shed light on the different components of each model, and how their Cost Drivers effect on the accuracy of cost estimations for software development projects.展开更多

Hence, it is important to define the rights and responsibilities of the parties, and relationships among them. In this context, well-designed and complete agreement is essential and necessary for the successfully completion of a construction project within the desired time, quality and budget. In this paper, it is aimed to analyze and compare the owner-contractor agreements in the Turkish and the US construction industry. First, the importance of construction contracts and contractual elements of an agreement is determined, and then, the standard owner-contractor agreement which is used in the Turkish construction industry is analyzed and compared with the US standard owner-contractor agreement. Finally, the differences between these agreements are put forward, the lack and deficiencies of Turkish standard agreement form are determined, and appropriate suggestions are improved.展开更多

文摘A polynomial model, time origin shifting model(TOSM, is used to describe the trajectory of a moving target .Based on TOSM, a recursive laeast squares(RLS) algorithm with varied forgetting factor is derived for tracking of a non-maneuvering target. In order to apply this algorithm to maneuvering targets tracking ,a tracking signal is performed on-line to determine what kind of TOSm will be in effect to track a target with different dynamics. An effective multiple model least squares filtering and forecasting method dadpted to real tracking of a maneuvering target is formulated. The algorithm is computationally more effcient than Kalman filter and the percentage improvement from simulations show both of them are considerably alike to some extent.
