As usual, the microgrid operates in grid-connect mode, but, when a fault occurs in the upstream grid, it should disconnect and shift into islanded operation mode. In grid-connect mode, the controlling power at the PCC is necessary management function rather than the frequency and voltage. However, the controlling the frequency and voltage is asked in islanded mode. To achieve these management g...

This paper is directed towards the definition of a systemic characteristic suitable for the “intelligent” core of a cooperative robot. A major issue in developing cooperative systems is the nature and degree of their autonomy. It is rare (rather, impossible!) that a communicated set of instructions for carrying out a task will be exhaustively complete, and with the passage of time the instructi...

In this note, we propose a full-duplex decode-and-forward cooperative diversity scheme based on code division with orthogonal complementary codes. We consider a simple case in which a single user is assisted by a single relay to achieve cooperative diversity. When the cooperation is full-duplex, the operational delay of the relay makes the channel asynchronous and this may cause multiple-access...

This paper presents a design and implementation of cooperative edge detection of multiple mobile robots in an indoor environment. We propose a method to fuse sensory data from two mobile robots at different locations based on Kalman filtering techniques. To demonstrate the proposed method, we constructed two mobile robots for experimental purpose. A USB Web camera was put at the front of each r...

This chapter presents a study on the interference caused by Secondary Users (SUs) due to miss-detection errors and its effects on the capacity-outage performance of the Primary User (PU) in a cognitive radio network assuming Rayleigh and Nakagami fading channels. The effect of beacon transmitter placement on aggregate interference distribution and capacity-outage performance is studied consider...

The performance of women agribusiness cooperatives in Oyo State, Nigeria was assessed in this study. The study employed a multi-stage sampling technique to select 6 women cooperative groups (aggregating to 175 individuals); 36 individual women; and 4 institutions across 6 LGAs in two agricultural zones of the State. Findings show that majority (55.6%) of the respondents belong to processing org...

A farmers’ group may have a collective character which formed in specific geographic and historic background its members’ relationships. And affect the way of operation expected behavior for members. In this study, I conducted comparative study two groups produce leafy vegetables. The first case is an agricultural cooperative, second contract farming with consumers’ cooperative. To analyze how ...

Cooperative vehicular networks require the exchange of positioning and basic status information between neighboring nodes to support vehicular applications. The exchange of information is based on the periodic transmission/reception of 1-hop broadcast messages on the so called control channel. The dynamic adaptation of the transmission parameters when broadcasting such messages will be key for ...

The globalization, the focusing on core capabilities and the expanding international division of labor lead to an economy that is increasingly shaped by logisticsand production networks. Regarding the simulation of logisticsand production systems (which are frequent objects of discrete simulation) this means that on the one hand the intensified enterprise-spreading processes in networks and the...

Increasing complexity and modularity of today’s WSAN applications impose demanding challenges on the system design. This especially affects real-time operation, resource sharing and dynamic memory management. Preemptive task systems are one way to retain good reactivity within dynamic environments. Yet, since memory is often too rare for static assignment, this rapidly leads to severe compositi...
