this paper presents a prediction model based on a new neuro-fuzzy algorithm for estimating time in construction projects. the output of the proposed prediction model, which is employed based on a locally linear neuro-fuzzy (llnf) model, is useful for assessing a project status at different time horizons. being trained by a locally linear model tree (lolimot) learning algorithm, the model is int...

In the implementation of projects, various obstacles are often encountered which cause delays have an impact not only on duration but also costs incurred. These constraints can be in form a lack resources, weather factors to social factors. Thus, it is necessary accelerate and optimize what done overcome delay. As well as efficient resource management. One acceleration methods that used Crashin...

Critical Success Factors (CSFs) are used to support and evaluate the success of a strategic and tactical approach in project implementation in order to increase the probability of success. This system is used by executors in project delivery to achieve improved performance capabilities with limited resources. The present paper aims to identify the impact of CSFs amongst the main elements involv...

Of many elements influencing the performance of a rotary compressor, the valve system plays an important role. In order to evaluate the performance, some basic experimental studies were made on the discharge coefficients and the proper dimensions of the valve system. Also, since the valve systems have previously been swdied by using rather simplified models, some effort' were made in this study...

In 1995, the Texas Department of Transportation (TxDOT) began reconstruction in Houston on a section of IH-10 with continuously reinforced concrete pavement (CRCP). The unique aspect of this project was the use of crushed concrete as both coarse and fine aggregates in the new concrete. No virgin aggregates were used. The primary objectives of this study were to evaluate (1) the material propert...
