The present paper investigates monitoring of fatigue cracks of a metal structure using an eddy current micro sensor. Fatigue cracks tend to occur at bolt-jointed structures on an aircraft. In order to detect the damage quantitatively, a kind of change-prone micro eddy current sensor is designed and fabricated with flexible printed circuit board (FPCB) technology. A forward semi-analytical model...

This study’s overarching aim is to establish the areal extent and characteristics of the rapid sugarcane expansion and land use change in São Paulo state (Brazil) as a result of an increase in the demand for ethanol, using Landsat type remotely sensed data. In 2003 flex fuel automobiles started to enter the Brazilian consumer market causing a dramatic expansion of sugarcane areas from 2.57 mill...

We consider a two echelon supply chain where a single retailer holds an inventory of finished goods to satisfy an i.i.d. customer demand, and a single manufacturer produces the retailer’s replenishment orders on a make-to-order basis. The objective of this paper is to analyse the impact of the retailer’s replenishment policy on total supply chain performance. We consider two strategies with reg...

We consider a firm that provides multiple services using both specialized and flexible capacity. The problem is formulated as a two-stage single-period stochastic program. The firm invests in capacity before the actual demand is known and optimally assigns capacity to customers when demand is realized. Sample applications include a car-rental company’s use of mid-sized cars to satisfy unexpecte...

current innovative lateral load carrying systems for tall buildings are those in which the lateral drift is limited to an allowable value without considerable influence on economy. this aim is achieved by using special systems capable of using maximum stiffness and strength capacity of individual structural elements. an effective structural solution in this respect is the use of outrigger brace...

Flexible and scalable networking solutions are required to offer more efficient bandwidth allocation and increased connectivity in submarine networks. In this regard, filterless optical networks based on agile edge nodes equipped with coherent transceivers and passive broadcast-and-select nodes are promising cost-effective options which allow for more flexible capacity allocation and resource o...

Plasmonic encoding composed of metallic nanostructures makes a great contribution to the practical application information encryption. However, most reports have so far shown preparation single or binary plasmonic patterns because technical difficulty assembling multiplex on platform, which cannot satisfy requirements high capacity for increasing security. Herein, we developed strategy based pl...
