Since information in engineering design problems can be both quantitative (Q T ) and qualitative (Q L ) in nature, combining both types of information can result in more realistic solution for real world optimisation problems. However, most of the approaches reported in literature are incapable of conducting optimisation search in such mixed environment. Therefore this paper proposes a mathemat...

The ideas used in experiments today were mostly in place by the first few decades of the 20th century. The procedures of comparing groups, assigning individuals to treatments, and statistically analyzing group comparisons had been developed by 1940. During the 1960s, the types of experimental designs were identified and the strengths (e.g., control over potential threats) of these designs speci...

We present the multi-factor quadratic reduced form model for pricing of credit risky securities. We use quadratic Gaussian processes to model the short term interest rate and the intensity of default showing that we get tractable formulas for the price of credit default swaps and credit default swaptions.

This paper demonstrates the usefulness and importance of the concept of honest times to financial modeling. It studies a financial market with asset prices that follow jump-diffusions with negative jumps. The central building block of the market model is its growth optimal portfolio (GOP), which maximizes the growth rate of strictly positive portfolios. Primary security account prices, when exp...

qualitative and quantitative research methods are different in some aspects but they complement each other in other aspects, as well. following widespread criticism of qualitative and quantitative research methods, there is increasing trend in using mixed research methods in social sciences in general and political science in particular. most advocates of pluralism attempted to fill the gap bet...
