This paper finds the essential differences between objects in terms of available attributes in a knowledge representation system (KR-system) where neither condition nor decision attributes are distinguished. We find these differences by using the concepts of "almost indiscernibility relation"...

The detrended fluctuation analysis (DFA) and the multifractal DFA (MF-DFA) techniques are employed to characterize the pseudorapidity (η) distribution of charged mesons produced in 28Si+Ag/Br interaction at 14.5 GeV/nucleon and 32S+Ag/Br interaction at 200 GeV/nucleon. Various multifractal...

This paper presents a conceptualized combined heat and power (CHP) scheme based on coal gasification and with a high temperature, pressurized solid oxide fuel cell (SOFC) in the topping cycle and a bottoming steam cogeneration cycle. An energy analysis is done for this CHP plant. The study...

This paper presents an Interactive Fuzzy Multi-Objective Linear Programming (IFMOLP) model for water quality management in a river basin. The IFMOLP model formulated will first evaluate dissolved oxygen (DO) concentrations or DO deficits at a point in different reaches depending on the overall...

This paper investigates how changes in fiscal policy can affect relative prices, optimal savings and steady state utility in a two-country, overlapping generations model of endogenous growth. We develop a simple model that combines Blanchard-type consumers with uncertain lifetimes, with an...

Firms that have foreign currency exposure face the problem of optimally hedging currency risk. In this paper, the firm adopts a hedging strategy that takes the risk-reward trade-off into account.

n this paper, we investigate the impact of regional trading arrangements (RTAs) on the environment. We propose an empirical model where RTAs, trade, growth and environmental quality are interrelated. As a result, an RTA in our model can impact the environment either directly or indirectly via...
