This paper focuses on the cooperative navigation of heterogeneous air-ground vehicle formations in a Global Navigation Satellite System (GNSS) challenged environment and proposes method based motion estimation regionally optimal path planning strategy. In formations, unmanned ground vehicles (UGVs) are equipped with low-precision inertial measurement units wireless range sensors, which interact...

Today due to increasing and evolving of electrical grids, the optimal and profitable energy production is among producers' major concerns. Thus, conventional ways of production and trading energy are being replaced by modern economical procedures. In addition, distributed energy resources (DERs) in form of renewable and conventional resources as well as responsive loads play an important role i...

Cooperative behavior among a group of agents is studied assuming adaptive interactions. Each agent plays a Prisoner's Dilemma game with its local neighbors, collects an aggregate payoff, and imitates the strategy of its best neighbor. Agents may punish or reward their neighbors by removing or sustaining the interactions, according to their satisfaction level and strategy played. An agent may di...

A new efficient enantioselective conjugate addition strategy has been disclosed to rapidly construct 2-amino-3-nitrile-chromene complexes via a multi-hydrogen-bond cooperative activation model.

Joint-stock cooperative company is not recognized in Commercial Code of Iran and the amendment bill of the Commercial Code adopted in 1968. This business entity has a unique description because of both being cooperative and having joint stock. It is a joint-stock company that is chartered based on Commercial Code of Iran, amendment bill of the Commercial Code adopted in 1968, and Principle 44 o...

We investigate fundamental characteristics of cooperative transmission in terms of power efficiency. To do this, we first propose an optimal power allocation method for wireless cooperative networks with Rayleigh fading. By introducing the concept of “cooperative region”, we then evaluate the average power efficiency which is defined as the ratio of total consumed transmit power with cooperatio...

As for multi-uninhabited aerial vehicle cooperative fire fighting problem, a multiuninhabited aerial vehicle cooperative control method was proposed based on consensus algorithm. multi-uninhabited aerial vehicle cooperative control problem was divided into two steps: 1) a multi-uninhabited aerial vehicle arrival simultaneous control strategy under influence of wind field based on consensus algo...

Existing theory, empirical, clinical and field research all predict that reducing the virulence of individuals within a pathogen population will reduce the overall virulence, rendering disease less severe. Here, we show that this seemingly successful disease management strategy can fail with devastating consequences for infected hosts. We deploy cooperation theory and a novel synthetic system i...

In a distributed cooperative environment, synchronization is a major issue. Especially when OFDM is employed in the physical layer, frequency offset synchronization is of great significance. In addition, transmitter and receiver IQ imbalances are known to be important implementation issues in OFDM systems. In this paper, the use of a strategy is investigated that enables blind estimation of Car...
