Abstract: An analytical model dealing with the problem of an expanded cylindrical cavity in an elastoplastic medium is presented. The constitutive material is assumed to be weightless, homogeneous, and isotropic; its resistance is ...

Abstract: This work aims to characterize the hydrodynamic and thermal behaviors in an innovative scraped surface heat exchanger (SSHE) equipped with helical ribbon by means of the numerical simulation approach. In this study, the ...

Abstract: A public–private partnership (PPP) is a contractual agreement between public-sector and private-sector partners allowing more private-sector participation than is traditional. The literature on PPP in the transportation ...

Abstract: The project influence curve postulates that planning efforts conducted early in a project can influence project success more than later efforts. Although front-end planning has been shown to influence project performance, ...

Abstract: Requests for information (RFIs) are a critical communication tool on construction projects. Preparing RFIs and responding to RFIs takes time and money. Unresolved RFIs or slow responses to RFIs may cause delays. The objective ...

Abstract: Alternative project delivery methods (APDMs) such as construction manager at risk (CMAR) and design-build (DB) rely on engaging the contractor earlier in the project, while design is still ongoing. Selecting the contractor ...

Abstract: The study reported in this paper has been conducted to shed light on the use of life cycle cost analysis (LCCA) in municipal organizations. The major objectives of the study are to identify the sources of data used in LCCA, ...

Abstract: NASA’s Space Station Freedom proposed hybrid power system includes photovoltaic arrays with nickel hydrogen batteries for energy storage and solar dynamic collectors driving Brayton heat engines ...
