We propose a comparative performance evaluation method for security protocols. We start by constructing a security protocol model where we assign a cost functions for each cryptographic operation. For each class of cryptographic operations (e.g. symmetric encryption, asymmetric decryption), we construct a polynomial function based on an exhaustive performance evaluation of cryptographic combina...

Developmental plans of the country emphasize on the exports-focused growth strategy, and export diversification is one of the most appropriate policies in this area. Export diversification moves from primary goods to industrial goods. Yet, export diversification, according to the principles of international trade, must be based on comparative advantage until to change value-added. Changes in th...

The agile methods are systems development methodologies currently used in the software development industry both internationally and in New Zealand. This article provides an overview of the agile methods, including the key publication of each method, the major influences on the agile methods, and describes comparative studies where analysis and comparison of methodologies has been carried out. ...

Background: Many comparative studies have been performed on effort estimation models. Linear regression (LR) and Estimation by Analogy (EbA) were often compared. The past research revealed that those comparative studies reported inconsistent results among performance measures. However, those studies seemed not to reflect actual or desirable study procedure. Aim: We aimed to examine performance ...

We analyze comparative risk aversion in a new way, through a comparative statics problem in which, for a cost, agents can shift from an initial probability distribution toward a preferred distribution. The Ross characterization arises when the original distribution is riskier than the preferred distribution and the cost is monetary, and theArrow–Pratt characterization ariseswhen the original di...
