The manuscript summarizes the results of a travel cost model developed for recreational angling in Michigan. The model and method are briefly described. The discussion focusses on how Great Lakes trout and salmon catch rates were related to angler behavior. The model is used to value changes in trout and salmon catch rates at Great Lakes fishing sites in Michigan. Fish population levels can be ...

Formulated as a least square problem under an constraint, sparse signal restoration is a discrete optimization problem, known to be NP complete. Classical algorithms include, by increasing cost and efficiency, matching pursuit (MP), orthogonal matching pursuit (OMP), orthogonal least squares (OLS), stepwise regression algorithms and the exhaustive search. We revisit the single most likely repla...

We report an intelligent image restoration approach by combining the geostatistical interpolation technique of punctual kriging and the machine learning approach of adaptive learning. Digital images degraded from Gaussian white noise are restored by first utilizing fuzzy logic for selecting pixels that need to be kriged. The concept of punctual kriging is then used to estimate the intensity of ...

Fast and accurate ridge detection in fingerprints is essential to each AFIS (Automatic Fingerprint Identification System). Smudged furrows and cut ridges in the image of a finger print are major problems in any AFIS. This paper investigates a new online ridge detection method that reduces the complexity and costs associated with the fingerprint identification procedure. The noise in fingerprint...

s: Ethernet Passive Optical Network (EPON) was proposed to overcome the bandwidth bottleneck at the Access Network due to its simplicity, cost effectiveness and wide spread deployment. A failure in access networks can cause serious problem, because access network transmit aggregated high-speed traffic from hundreds of subscribers. Protection and restoration mechanisms have been applied in backb...

introduction: the restoration of endodontically treated teeth is a topic that has been studied extensively but it is still a challenge for dental practitioners. the aim of this study was to evaluate fracture resistance, fracture patterns and fracture location of endodontically treated human maxillary premolars restored with direct and indirect composite resin and ceramic restoration. methods: e...

conclusions the clinical success rates of endodontically treated premolars restored with fiber posts and direct composite restorations, direct composite restorations with cusp capping and simple direct composite restoration were perfect after one year of follow-up evaluation. background endodontically treated teeth need to be restored in a manner to provide protection for the remaining tooth st...

We design a choice experiment to examine public preferences for coastal dune ecosystem restoration in the U.S. Pacific Northwest. Dunes are good whose natural state is now rare. Respondents asked choose among hypothetical projects that vary by project size, quality, recreation access, flooding risk, and cost. Restoration quality defined as closeness ecosystem. find increasing results significan...

Innovative methodology is developed for Back to the Future (BTF) restoration policy analysis to aid long-term strategic planning of ecosystem-based restoration in marine ecosystems. Massbalance and dynamic ecosystem simulation models (Ecopath with Ecosim: EwE) are developed to represent the marine system of northern British Columbia as it appeared in 1750, 1900, 1950 and 2000 AD. Time series st...

This paper studies the optimal production run length for the economic manufacturing quantity model with maintenance, scrap and rework actions under the imperfect production system where the process state is classified as either in-control or out-of-control. Suppose that a production process starts to produce in an in-control state, however, after a period of time, the process may evolve from th...
