Each of two parties P I and P 2 holds an n -bit input, x and y, respectively. They wish to privately compute the value off (x 'Y). That is, PI should not learn any additiorlal infonnation about y (in the infonnationtheoretic sense) other than what follows from its input x and the function value, f (x 'Y), and similarly, P 2 ~hou1d not learn any additional infonnation about x . In this paper we ...

ion levels, called reusable assets, these elements have to be stored in an adequate repository [4,5]. The supported abstraction levels are requirements level, design level and implementation level. Around the a reuse model has been defined, which is articulated over three edges, the technical model, the process model and the qualification model. The technical reuse model presents a duality comp...

Value-added Tax versus Social Security Contributions In order to alleviate unemployment it is often recommended to reduce social security contributions (SSC) and to compensate for the ensuing loss in revenues by a rise in the value-added tax (VAT). Assuming unemployment to be caused by efficiency wages, it is shown that a balanced-budget shift from a payroll tax to a VAT will increase employmen...

the diamondback moth, plutella xylostella (linnaeus, 1758) (lep.: plutellidae) is the most destructive insect pest of crucifer plants throughout the world. in order to study its seasonal population fluctuation, sampling was conducted in the cauliflower fields of south of tehran from late may until october 2011. one hectare cauliflower field in the middle of a large field was randomly selected i...

We consider a classical risk model with the possibility of reinsurance. Moreover, in one of the models also investment into a risky asset is possible. The insurer follows the optimal strategy. In this paper we find the Cramér-Lundberg approximation in the small claim case and prove that the optimal strategy converges to the asymptotically optimal strategy as the capital increases to infinity. 1...
