Nowadays, utilization of renewable energies for satisfying electricity demand has received more interest, and renewable electricity generation has been growing in the world. This study addresses the operational planning of a renewable electricity supply chain over a multi-period planning horizon. The purpose of this study is to maximize total profit and to optimize the operational decisions rel...

In this article, a finite horizon, multi product and multi period economic order quantity like seasonal items is considered where demand rate is deterministic and known but variable in each period. The order quantities of items come in batch sizes and the end of the period order quantity and, consequently, demand of customers are zero. In addition, storage space is constrained and the problem...

1 This paper describes a two-stage equilibrium travel demand model. The unique feature of this model is 2 that it takes time-of-day traffic counts instead of land use and demographic data as inputs to derive spatial 3 and temporal travel demand patterns. The first stage of the model is a traffic count-based trip matrix 4 estimator; the second stage is an elastic-demand network flow estimator, w...

Microeconomic theory develops demand and supply curves to determine the market equilibrium for commodity exchange. The demand and supply functions are the result of consumers utilities and producers production functions for different product combinations. The interaction is a game-theoretic approach to determine the quantity and prices with which goods and services are traded. Economic theory w...

In each time period, the demand of passengers for each route are finite and airlines compete for earning more profits. The complex competition among airlines causes problems, such as complicating flight planning and increasing empty seats for some routes. These problems increase air pollution and fuel consumption. To solve these problems, this research studies the cooperation of the airlines wi...

In order for a model of rational agency to be used for multi-agent social interaction, the model must be extended to account for communicative behaviors that are ineecient for one agent, but which increase the eeciency of the interaction of two agents in a dialogue. In this paper, we argue that naturally occurring communicative behaviors are often directed at the resource limits of the other ag...

Given a set S with real-valued members, associated with each member one of two possible types; a multi-partitioning of S is a sequence of the members of S such that if x, y ∈ S have different types and x < y, x precedes y in the multi-partitioning of S. We give two distribution-sensitive algorithms for the set multi-partitioning problem and a matching lower bound in the algebraic decision-tree ...

We present Privacy Scope, a new system that tracks the movement of sensitive user data as it flows through off-the-shelf applications. Privacy Scope uses application-level dynamic taint analysis, implemented with dynamic binary translation tools, to let users run applications in their own environment while pinpointing information leaks, even when the sensitive data is encrypted. The system is m...

Magnetic flux leakage (MFL) inspection is one of the most important and sensitive nondestructive testing approaches. For online MFL inspection of a long-range railway track or oil pipeline, a fast and effective defect profile estimating method based on a multi-power affine projection algorithm (MAPA) is proposed, where the depth of a sampling point is related with not only the MFL signals befor...
