We consider a barter market with multiple types of indivisible goods. Konishi et al. [J. Math. Econ. 35 (2001) 1–15] showed that the core of this market may be empty. We define a normal form game for this market and consider its equilibrium outcomes. Assuming separable strict preferences, we show that the game has a unique Coalition-proof Nash allocation. This Coalition-proof Nash allocation is...

futures contract is one of the most important derivatives that is used in financial markets in all over the world to buy or sell an asset or commodity in the future. pricing of this tool depends on expected price of asset or commodity at the maturity date. according to this, theoretical futures pricing models try to find this expected price in order to use in the futures contract. so in this ar...

Autonomous vehicles require the ability to build maps of an unknown environment while concurrently using these maps for navigation. Current algorithms for this concurrent mapping and localization (CML) problem have been implemented for single vehicles, but do not account for extra positional information available when multiple vehicles operate simultaneously. Multiple vehicles have the potentia...

The use of unmanned vehicles in Reconnaissance, Surveillance, and Target Acquisition (RSTA) applications has received considerable attention recently. Cooperating land and air vehicles can support multiple sensor modalities providing pervasive and ubiquitous broad area sensor coverage. However coordination of multiple air and land vehicles serving different mission objectives in a dynamic and c...

I propose several mean-reversion jump-di usion models to describe spot prices of energy commodities that may be very costly to store. I incorporate multiple jumps, regime-switching and stochastic volatility into these models in order to capture the salient features of energy commodity prices due to physical characteristics of energy commodities. Prices of various energy commodity derivatives ar...

In this paper, we study a two-period pure exchange economy with idiosyncratic uncertainty, moral hazard and multiple consumption goods. We consider two different market structures: contingent commodity markets on the one hand, and financial plus spot commodity markets on the other hand. We propose a competitive equilibrium concept for each market structure. We first verify that it is possible t...

A methodology for cooperating multiple vehicles in a reconnaissance problem is proposed. A team of vehicles is used in surveying multiple targets potentially at different priority levels. The overall objective is to minimize the uncertainty on locations of targets using cooperative estimation in minimum time. Because the performance of the estimation highly depends on trajectories of observers,...

Vehicle tracking has a wide variety of applications. The image resolution of the video available from most traffic camera system is low. In many cases for tracking multi object, distinguishing them from another isn’t easy because of their similarity. In this paper we describe a method, for tracking multiple objects, where the objects are vehicles. The number of vehicles is unknown and varies. W...

abstract comparative advantage is an economic term which is used to compare potential and actual production capacity of a country in a given commodity with the rest of the world. therefore, researches in this field could have a dual approach. in one hand it could demonstrate country’s production capacity in the production of commodities that are not produced yet and in the other hand it can ill...

In recent years, car-sharing systems have been announced as a way to increase mobility and to decrease the number of single-occupant vehicles, congestion, and air pollution in many parts of the world. This study presents a linear programming model to optimize one-way car-sharing systems for electric cars considering the depreciation costs of chargers and vehicles as well as relocation cost of v...
