We present two cooperative strategies in area coverage that are aimed to be applied in agricultural robotics domain. Current strategies in this domain rely on explicit forms of communication for task allocation and coordination. One issue with these approaches is the loss of communicating signal. This paper presents two approaches (FIFO, and LIFO) for task allocation and coordination that relie...

Study selection and assessment: published and unpublished randomised controlled trials (RCTs) in any language that compared specific probiotics with placebo or no probiotic in adults and children with acute diarrhoea (,14 d) that was proven or presumed to be caused by an infectious agent. 2 independent reviewers assessed the methodological quality of individual studies in terms of generation of...

This work presents joint subcarrier, power and bit allocation schemes for multi-user OFDM based overlay cognitive radio under constraints on primary user throughput loss and total secondary user transmitted power. Closed form for expressions for the optimal power and bit allocations are initially derived. Subsequently, optimal and suboptimal algorithms to realise the joint subcarrier, power and...

This paper presents an adaptive actuators allocation scheme that is fault-tolerant with respect to actuator faults or loss of effectiveness. The main idea here is to use an ad-hoc online parameter estimator coupled with an allocation algorithm to perform on-line control reconfiguration. Two simple algorithms are proposed for nonlinear discrete-time systems. The main properties of the algorithms...

This paper presents a preliminary adaptive actuators allocation scheme that is fault-tolerant with respect to actuator faults or loss of effectiveness for overactuated networked systems. The main idea here is to use an ad-hoc online parameter estimator coupled with an allocation algorithm to perform on-line control reconfiguration. Two simple algorithms are proposed for nonlinear discretetime s...

Adaptive designs are used in phase III clinical trials for skewing the allocation pattern towards the better treatments. We use optimum design theory to provide a skewed biased-coin procedure for sequential designs with continuous responses. The skewed designs are used to provide adaptive designs, the performance of which is studied numerically for designs with three treatments. Important prope...

Optical Burst Switching (OBS) has been developed as an efficient switching technique to exploit the capacity provided by Wavelength Division Multiplexing (WDM) transmission technology for the next generation optical Internet. One critical design issue in OBS is how to provide Quality-of-Service (QoS) in optical networks. This thesis focuses on providing QoS in OBS networks. Two basic models for...

Aggregate loss functions are loss functions for counts of areas where the count itself is of interest. Proportional loss functions are loss functions for counts of areas where the count as a proportion of a total is of interest. To date, much of the work on adjustment has concentrated on aggregate loss functions. A question is whether this effort will necessarily produce estimated counts whi.ch...

Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources. To provide cloud computing services economically, it is important to optimize resource allocation under the assumption that the required resource can be taken from a shared resource pool. In addition, to be able to provide processing ability and storage capacity, it...
