Project managers are grappling with a variety of risks today as a result of increasing complexity and dynamics of projects in different stages of project life cycle. Thus, it seems quite necessary to employ an efficient risk management process that can overcome the shortcomings of traditional methods in order to handle such complexities and reach the optimal project management. This matter is e...

The U.S. Army Corps of Engineers elevated Zoar Levee and Diversion Dam to a Dam Safety Action Class I (urgent and compelling) ranking due to seepage concerns. An accelerated program is in progress to address project deficiencies which include seepage through the levee’s glacial outwash foundation, through a fractured rock knoll beneath the levee, and through the dam’s fractured rock abutments a...

Abstract We exploit locally exogenous variation from the Blitz bombings to quantify effect of redevelopment frictions and identify agglomeration economies at a micro-geographic scale. Employing rich location office rental transaction data, we estimate reduced-form analyses spatial general equilibrium model. Our demonstrate that more heavily bombed areas exhibit taller buildings today, elasticit...

Most contemporary fourth-generation languages (4GLs) are tightly coupled with the relational database and other subsystems provided by the vendor. As a result, organisations wishing to change database vendors are typically forced to rewrite their applications using the new vendor’s 4GL. The anticipated cost of this redevelopment can deter an organisation from changing vendors, hence denying it ...

A model is created for assessing the redevelopment potential of brownfields. The model is derived from a space and time conceptual framework that identifies and measures the surface and subsurface risk factors present at brownfield sites. The model then combines these factors with a contamination extent multiplier at each site to create an index of redevelopment potential. Results from the appl...

Like blighted urban areas, indigenous nations in the U.S. often have abandoned underutilized commercial or industrial properties with potential environmental contamination within the confines of their reservations. Like urban brownfields, often contamination problems are discovered long after the responsible parties have disappeared. Financial incentives, tools, and risk-management techniques h...

in this paper, we describe our implementation of an interior point algorithm for large scale systems. first we identify system with small and medium methods convex optimization, then we use interior point method for identification. finally we offer an interior point method that uses nonlinear cost function and see that we achieve a good trade-off between error and cpu time. actually, in this pa...
