Cooperative schools: Learning to be cooperative in a changing educational landscape
… this research considers what it means to be a cooperative school in the 21st Century and how this ideological stance impacts on stakeholders’ experiences. The research sought the perceptions and experiences of 99 staff members, pupils, governors and wider community, to illuminate the act of …

Cooperative and Non-Cooperative Flow Control in Mobile Ad Hoc Networks
… flow control has been studied in a cooperative network environment. Such cooperative behavior is not a realistic assumption in a public MANET formed by a random group of strangers. Users in this network are likely to behave selfishly, by refusing to forward other users' packets. …

Topics in Cooperative Control
… thesis are networked dynamic systems and related cooperative control problems. We shall contribute a number of technical results to the stability theory of switched positive systems, and present a new cooperative control paradigm that leads to several cooperative control schemes which allow …

Low-complexity near-optimum detection techniques for non-cooperative and cooperative MIMO systems
… and complexity in the context of uncoded non-cooperative Multiple-Input Multiple-Output (MIMO) systems using coherent detection. Particular attention is devoted to Spatial Division Multiple Accessing (SDMA) aided Orthogonal Frequency Division Multiplexing (OFDM) systems, which are considered …

Wireless Cooperative Communication and Networking
<p>Cooperative communication can achieve diversity gain and increase the channel capacity. This paper proposes a novel cooperative scheme called Cooperative Step-Wise Demodulation, which utilizes low level demodulation to demodulate high level modulated signal cooperatively. This paper focuses …

Towards computer supported cooperative design
… first reviews the literature about the nature of cooperative design activity and its technological support. It is noted that knowledge of how designers work together in real-world settings is less than complete. Moreover, after over a decade of developments in Computer Supported Cooperative Work, …

Cooperative behavior of motor proteins
The cytoskeletal motor protein kinesin-1 (conventional kinesin) is the fast carrier for intracellular cargo transport along microtubules. So far most studies aimed at investigating the transport properties of individual motor molecules. However, the transport in cells usually involves the …

Activity Management in Cooperative Environments
… the popularity of Internet, computer supported cooperative applications in software and engineering environments have begun to emerge. However, most of them lack the support from database systems. The need for database support in these applications has become more important than ever before …

Optimal cooperative power-limited rendezvous
Minimum-fuel rendezvous of two power-limited low-thrust spacecraft is investigated. Both vehicles are active and provide thrust to complete the rendezvous. Total propellant consumption is minimized. Two gravitational field models are investigated: the Clohessy-Wiltshire linearized field and the …

Conflict resolution in cooperative design
Design is increasingly becoming a cooperative endeavor carried out by multiple agents with diverse kinds of expertise. The development of tools and underlying theories for supporting cooperative design has lagged, however, behind the growing needs implied by this evolution.

Cooperative learning in educational gaming
… we created both a single-player experience and a cooperative version. We expected that players of the cooperative game would learn more quickly through discussion and coordination. Students played both versions, and then answered short questions regarding their experience. Contrary to our …

Cooperative multicast in wireless networks
… thesis will construct and test the value of a cooperative system where the routing and transmission are done together by using several of the radios in the space to help, rather than interfere. The novel element is wireless, cooperative multicast that could be the basis for a new broadcast …

Cooperative exploration under communication constraints
The cooperative exploration problem necessarily involves communication among agents, while the spatial separation inherent in this task places fundamental limits on the amount of data that can be transmitted. However, the impact of limited communication on the exploration process has not been fully …

Cooperative checkpointing for supercomputing systems
… This thesis presents such a technique, called cooperative checkpointing, and models its behavior as an online algorithm. Where C is the checkpoint overhead and I is the request interval, a worst-case analysis proves a lower bound of (2 + [C/I])-competitiveness for deterministic cooperative …

Cooperative routing in wireless networks
… the problem of finding the minimum energy cooperative route for a wireless network under idealized channel and receiver models. Fundamental to the understanding of the routing problem is the understanding of the optimal power allocation for a single message transmission between two sets of …
