We propose and estimate fundamental models for natural gas prices. We compare how well these models, as well as univariate statistical time series models of NG prices and the NYMEX futures price for natural gas, forecast spot gas prices. We find that a univariate time series model that incorporates fundamental variables related to production, storage, weather, and aggregate output performs best...

In recent years, Stackelberg Security Games have been successfully applied to solve resource allocation and scheduling problems in several security domains. However, previous work has mostly assumed that the targets are stationary relative to the defender and the attacker, leading to discrete game models with finite numbers of pure strategies. This paper in contrast focuses on protecting mobile...

Our goal is to find a mixed strategy (probability distribution on possible plays) for Row which maximizes their expected winnings no matter what strategy Col chooses to execute. Let z denote the winnings of Row player using strategy (x1, x2). Then the solution to the following linear program describes the optimal strategy for Row, since based on any strategy Row chooses, Col may choose a pure s...

in this paper, we present an application of intuitionistic fuzzyprogramming to a two person bi-matrix game (pair of payoffs matrices) for thesolution with mixed strategies using linear membership and non-membershipfunctions. we also introduce the intuitionistic fuzzy(if) goal for a choiceof a strategy in a payoff matrix in order to incorporate ambiguity of humanjudgements; a player wants to max...

Finding new ways to compete in competitive markets is the essence of strategic thinking and marketing strategy. This issue has always been addressed by the experts and scholars of economics and management overrecent decades. In this regard, the present study explores the entrepreneurial strategies to gain a competitive advantage in IlamProvincemedicinal plants. This studyemployed a mixed-method...

This study investigates the directions and strengths of the relationships among Media based internal communications and affective commitment to strategy implementation in Bank Sepah. This is a descriptive, applied research and Mixed quantitative and qualitative methods were used to collect data. Firstly focus group interviews were used to identify the factors of media effecting affective commit...

Recently, processing of queries on linked data has gained attention. We identify and systematically discuss three main strategies: a bottom-up strategy that discovers new sources during query processing by following links between sources, a top-down strategy that relies on complete knowledge about the sources to select and process relevant sources, and a mixed strategy that assumes some incompl...

A mixed-methods study was conducted to examine the effects of self-regulated learning (SRL) strategy training on learners’ achievement, motivation and strategy use in a web-enhanced College Success course at a community college in southeast US. It was found that training assisted with students’ overall course performance and accomplishment of long-term tasks, enhanced students’ self-satisfactio...

Recent applications of game theory in security domains use algorithms to solve a Stackelberg model, in which one player (the leader) first commits to a mixed strategy and then the other player (the follower) observes that strategy and bestresponds to it. However, in real-world applications, it is hard to determine whether the follower is actually able to observe the leader’s mixed strategy befo...
