This paper proposes a novel passivity cascade technique (PCT)-based control for nonlinear inverted pendulum systems. Its main objective is to stabilize the pendulum’s upward states despite uncertainties and exogenous disturbances. The proposed framework combines estimation properties of radial basis function neural networks (RBFNs) with attributes framework. unknown terms system are estimated u...

This research develops two models to consider retailer sales promotion and manufacturer trade under demand uncertainty. The objective of the first model is determine retailer’s optimal promotional effort order quantity while maximizing profit exogenous promotion. second extends manufacturer’s endogenous decisions. For these models, three different policies (off-invoice, scan-back, unsold-discou...

Prior literature has shown that managerial short-termism causes only over-investment at the more efficient type firms for the signaling purpose. Two fundamental assumptions are typically made: the manager’s shortterm incentive is exogenous and the setting of information asymmetry guarantees the manager’s possible payoff functions satisfy the single-crossing condition. In an operations context, ...

The liberalization of electricity markets in recent years has enhanced competition among powergenerating firms facing uncertain decisions of competitors and thus uncertain prices. At the same time, promoting renewable energy has been a key ingredient in energy policy seeking to de-carbonize the energy mix. Public incentives for companies to invest in renewable technologies range from feed-in ta...

Increasingly sophisticated knowledge requires an inclusive knowledge representation that facilitates the integration of independently-generated information arising from different kind of efforts. The use of semantic web technologies addresses the reality of diverse interests on an ontology merging and supports knowledge discovery over that. Significant research efforts in the Semantic Web are r...

Landing is a challenging flight phase for automatic control of fixed-wing aircraft. For unmanned air vehicles in particular, it is imperative that model uncertainty be considered in the control synthesis. These vehicles tend to have limited sensors and instrumentation, yet must achieve good performance in the presence of modelling errors and exogenous inputs such as turbulence. Quantitative Fee...

Using a new dataset of currency option prices, we study the evolution of investor confidence in 1992-1998 over the chance of individual currencies to converge to the Euro. Convergence risk, which may reflect uncertainty over policy commitment as well as exogenous fundamentals, induces a level of implied volatility in excess of actual volatility (volatility wedge). We show formally that confiden...

Background & Aim: The world production and consumption of essential oils and perfumes are increasing very fast. Lippia citriodora H.B.K. is an herbal species mainly used as a spice and medicinal plant. Endogenous levels as well exogenous application of plant growth regulators (PGR) could affect essential oil production and chemical compositions. Experimental: To study the effect of ex...

How does asset redeployability affect corporate investment decisions, particularly when economic uncertainty changes? To address this question, we construct measures of acrossindustry redeployability of assets and study exogenous increases in uncertainty spurred by major economic and political events, including the First Gulf War and the 9/11 Terrorist Attack. We find that after an increase in ...

We introduce a version of the DICE-2007 model designed for uncertainty analysis. DICE is a wide-spread deterministic integrated assessment model of climate change. Climate change, long-term economic development, and their interactions are highly uncertain. The quantitative analysis of optimal mitigation policy under uncertainty requires a recursive dynamic programming implementation of integrat...
