Factorization of large numbers has been a constant source of interest in cryptanalysis. The fastest known algorithm for factoring large numbers is the Number Field Sieve (NFS). The two most time consuming phases of NFS are Sieving and Matrix Step. In this paper, we propose an efficient way of implementing the Matrix step in reconfigurable hardware. Our solution is based on the MeshRouting metho...

Solutions proposed in bibliography for multiple user allocation on the sub-bands of an OFDM system, adopting multiple antennas, require highly computational effort and consider delay insensitive applications. Our approach tends to overcome all these limitations relaxing some hypothesis in order to give a feasible solution. The proposed algorithm can be applied to a real multiple antenna OFDM sy...

In this paper, I address the what, the how, and the why of moral phenomenology. I consider first the question What is moral phenomenology?, secondly the question How to pursue moral phenomenology?, and thirdly the question Why pursue moral phenomenology? My treatment of these questions is preliminary and tentative, and is meant not so much to settle them as to point in their answers’ direction.

The paper studies insurance with moral hazard in a system of contingent-claims markets. Insurance buyers are modelled as Cournot monopolists or oligopolists. The other agents condition their expectations on market prices, as in models of rational-expectations equilibrium with asymmetric information. Thereby they correctly anticipate accident probabilities corresponding to effort incentives indu...

When thinking about ethics, technology is often only mentioned as the source of our problems, not as a potential solution to our moral dilemmas. When thinking about technology, ethics is often only mentioned as a constraint on developments, not as a source and spring of innovation. In this paper, we argue that ethics can be the source of technological development rather than just a constraint a...

This paper provides the framework for a payment plan based on inspection results in the delegation of inspection agencies. The paper deals with two cases—that in which one inspector checks the quality of the inspection object (e.g., a design drawing of building) and that in which two inspectors check it simultaneously. The paper points out the applicability of a penalty only in the framework wi...

The assumption of traditional character educators that children build moral literacy from reading or hearing moral stories is challenged based on research findings. First, research in text comprehension indicates that readers do not understand texts the same way due to differences in reading skill and background knowledge. Second, moral comprehension research indicates that moral arguments are ...

The “spanning condition”describes a situation where the agent’s e¤ort determines the weights placed on two distinct technologies. Su¢ cient conditions are known under which the …rst-order approach (FOA) is valid when the spanning condition holds. In this paper, a complete solution to the problem is provided. Thus, the problem is solved even in cases where the FOA is not valid. The solution has ...
