This study aims to evaluate the fatigue phenomenon in recycled hot asphalt mixture for an surface layer. Eight mixtures were evaluated laboratory, and samples divided into two major groups: four containing neat binder RAP from source 1 (RAP with binder) SBS-modified 2 binder). The levels of incorporation 0%, 10%, 20%, 30% relation total weight mixtures. followed Marshall mix design methodology....

Flooding is a growing problem, which affects more than 10% of the UK population. The cost of damage caused by flooding correlates closely with the warning time given before a flood event, making flood monitoring and prediction critical to minimizing the cost of flood damage. This paper describes a wireless sensor network for flood warning which is not only capable of integrating with remote fix...

We examine the agent’s investment level in a project with potential high-risk consequences. In order to reduce uncertainty, the agent may acquire costly information. We first find that both a very optimistic agent (who thinks that the damage has low probability to occur) and a very pessimistic agent never acquire information because information is not valuable for them. Yet, with information, t...

This note studies the optimal inspection policies in a supply chain in which a manufacturer purchases components from a supplier but has no direct control of component quality. The manufacturer uses an inspection policy and a damage cost sharing contract to encourage the supplier to improve the component quality. We find that all-or-none inspection policies are optimal for the manufacturer if t...

Aside from the obvious suffering endured by patients, the financial impact of pressure damage on healthcare providers is also a factor. However, as well as the costs associated with direct wound treatment, there is also the cost of increased length of stay, surgical intervention, extended rehabilitation, loss of earnings and long-term care provision. This ‘total healthcare’ cost of pressure dam...

This paper compares the relative efficiencies of pollution taxes, pollution standards, and the auctioning of pollution rights when the marginal damage function or marginal control cost are subject to uncertainty. In the first case, we find that all instruments yield the same expected social surplus. In the latter case, the choice of the optimal instrument depends, in general, on the relative el...

The assessment of seismic performance of existing structures is becoming an important problem in earthquake engineering. Some important ructures are considerably old and, therefore, their strengths and ductilities are less than strength and ductility demands because of changes in codes and design methodologies. Such structures must be strengthened to resist future earthquakes. First, a structur...

In this paper, a crack localization method for Euler-Bernoulli beams via an efficient static data based indicator is proposed. The crack in beams is simulated here using a triangular variation in the stiffness. Static responses of a beam are obtained by the finite element modeling. In order to reduce the computational cost of damage detection method, the beam deflection is fitted through a poly...

This study developed an integrated global-local approach for locating damage on building structures. A damage detection approach with a novel embedded frequency response function damage index (NEFDI) was proposed and embedded in the Imote2.NET-based wireless structural health monitoring (SHM) system to locate global damage. Local damage is then identified using an electromechanical impedance- (...

Model-based non-destructive evaluation proceeds measuring the response after an excitation on an accessible area of the structure. The basis for processing this information has been established in recent years as an iterative scheme that minimizes the discrepancy between this experimental measurement and sequence of measurement trials predicted by a numerical model. The unknown damage that mini...
