This paper analyzes the theoretical problem of the real option with barrier. It models an investment decision with a double irreversibility concern: investing is irreversible, but waiting runs the risk of loosing the opportunity to invest. The optimal strategy leads to earlier investment when the barrier increases, or when uncertainty decreases. Uncertainty has ambiguous effects on the expected...

This paper will highlight various methods utilized for cnvironmcntal compliance with solvent coating and laminating applications. Discussion will summarize the recovery and oxidation alternatives, including a brief overview of thc advantages and disadvantages. The paper concludes by focussing on more specific examples of solutions, including capture hooding and enclosures, dryer air flow scheme...

Monitoring and surveillance are important aspects in modern wireless sensor networks. In applications of wireless sensor networks, it often asks for the sensors to quickly move from the interior of a specified region to the region’s perimeter, so as to form a barrier coverage of the region. The region is usually given as a simple polygon or even a circle. In comparison with the traditional conc...

An approach to improve the lifetime of air plasma sprayed (APS) thermal barrier coatings (TBCs) by modifying the interfacial microstructure has been reported. The laser powder deposition technique was employed to fabricate the mesh structure (with the same composition as the bond coat) at the ceramic–substrate interface. After thermal cycling test, the APS TBCs with the mesh exhibited a much le...

In the present study, we tested the hypothesis that an instinctive barrier to nonsuicidal self-injury (NSSI)—the aversion to self-cutting stimuli—is diminished in people who engage in NSSI. In a sample of 86 noninjurers and 58 people with a history of self-cutting, we found that NSSI was associated with substantially reduced aversion to self-cutting stimuli across measures of both implicit (d =...

This paper presents a comprehensive extension of pricing two-dimensional derivatives depending on two barrier constraints. We assume randomness on the covariance matrix as a way of generalizing. We analyse common barrier derivatives, enabling us to study parameter uncertainty and the risk related to the estimation procedure (estimation risk). In particular, we use the distribution of empirical ...

An understanding of the basic structure, viscoelastic properties and interactions of mucin glycoproteins is of considerable interest to food science because of the important protective role that these macromolecules play in gastric physiology. The polymeric/colloidal behavior of mucins is complicated due to their large size (2–50 MDa) and complex structure with domains involving hydrophilic/hyd...

Within most industry segments, significant financial losses may be incurred due to accelerated wear of various components. In order to minimize the effects of mechanical wear and extend product life, thermal spray coating solutions introduced into production and is further developing them to meet even more demanding wear applications. Applying coatings using thermal spray is an established indu...

A wireless sensor can detect the presence of an intruder in its sensing range, and is said to cover the portion of a given barrier that intersects with its sensing range. Barrier coverage is achieved by a set of sensors if every point on the barrier is covered by some sensor in the set. Assuming n identical, anonymous, and relocatable sensors are placed initially at arbitrary positions on a lin...
