Cost-Benefit Analysis is a method to assess the effects of policies and projects on social welfare. CBAs are usually applied in a top-down approach, in the sense that a decision-making body first decides on which policies or projects are to be considered, and then applies a set of uniform criteria to identifying and valuing relevant cost and benefit flows. This paper investigates the possible a...

Any books that you read, no matter how you got the sentences that have been read from the books, surely they will give you goodness. But, we will show you one of recommendation of the book that you need to read. This duality of the mind a bottom up approach toward cognition is what we surely mean. We will show you the reasonable reasons why you need to read this book. This book is a kind of pre...

Failure is an ordinary characteristic of large-scale distributed environments. Resubmission is a general strategy employed to cope with failures in grids. Here, we analytically and experimentally study resubmission in the case of random brokering (jobs are dispatched to a computing elements with a probability proportional to its computing power). We compare two cases when jobs are resubmitted t...

The optimal way for introducing a product line is to set up a completely new product line by developing a reuse infrastructure for the whole range of products right from the start. However, in practice, product line engineering is frequently introduced by a company after having developed a number of products separately (i.e. in single system engineering). The challenge then consists of defining...

Results from a numerical study examining micro-/macrorelations linking local geometry parameters to sound absorption properties are presented. For a hexagonal structure of solid fibers, the porosity phi, the thermal characteristic length Lambda('), the static viscous permeability k(0), the tortuosity alpha(infinity), the viscous characteristic length Lambda, and the sound absorption coefficient...

Validators are used to ensure that internet based services present information in an adequate way to the end users. However, today’s validators are not transparent making it difficult for the users to understand their feedback. To enhance the transparency we propose a MDE based approach to program validation, where domain requirements are presented in a metamodel. The validation is based on a b...
