Adaptive informative sampling with autonomous underwater vehicles: Acoustic versus surface communications

Stephanie Kemna, David A. Caron, Gaurav S. Sukhatme
2016 OCEANS 2016 MTS/IEEE Monterey  
Simulation experiments with two AUVs, comparing no data sharing with timed surfacing for data sharing, show that the system performs better when data is shared.  ...  Previous works have shown the benefits of using informative adaptive sampling approaches for field estimation over running standard surveys.  ...  For multi-vehicle parallel and timed data sharing approaches, the data measurements are shared after the pilot, for acomms approaches measurements are shared continuously during the pilot survey.  ...

Non-intrusive Performance Management for Computer Services [chapter]

Magnus Karlsson, Christos Karamanolis
2006 Lecture Notes in Computer Science  
This paper evaluates Proteus, a prototype implementation of the proposed approach, on two different services: a 3-tier e-commerce system and a networked file service.  ...  Thus, some form of resource control is required to ensure contractual performance targets for service customers under dynamic workload and system conditions.  ...  On a high level, an adaptive controller has two sets of inputs, a set of performance measurements from the system and a set of desired performance references.  ...

2013 Lecture Notes in Computer Science  
Multi-core processors are increasingly considered as execution platforms for embedded systems because of their good performance/energy ratio.  ...  It may severely reduce the performance of tasks executed on the cores, and it increases the complexity of timing analysis and/or decreases the precision of its results.  ...  Hence, it is also a measure for the suitability of a multi-core architecture for time-critical embedded systems.  ...

A Novel Method for Online Detection of Faults Affecting Execution-Time in Multicore-Based Systems

Stefano Esposito, Massimo Violante, Marco Sozzi, Marco Terrone, Massimo Traversone
2017 ACM Transactions on Embedded Computing Systems  
This paper proposes a bounded interference method, based on statistical evaluations, for online detection and tolerance of any fault capable of causing a deadline miss.  ...  The proposed method requires data that can be gathered during the profiling and worst-case execution time (WCET) analysis phase.  ...  Fig. 1 . 1 Time diagram showing four tasks on as many cores. The scheduling uses a time multiplexing approach for accesses to the shared memory.  ...

2013 2013 IEEE International Conference on Cluster Computing (CLUSTER)  
In this paper, we present a novel approach of how to correlate the performance behavior of applications running side by side.  ...  Mapping performance data related to shared resources onto these time slices, we are able to establish the simultaneity of their usage across jobs, which can be indicative of inter-application interference  ...  Although approaches [9] , [10] exist to silently create performance profiles of all jobs running on a system and thus to capture all those that share the system at a given time, the ability to establish  ...

2006 Lecture Notes in Computer Science  
In this paper, we try to remedy this situation by performing a large scaled measurement study on Gnutella with the help of some new crawling approaches.  ...  Our measurements show that the assumption that query arrival follows Poisson distribution may not be true in Gnutella and most peers incline to share files of very limited types, even when MP3 files are  ...  We are also in the process of building file spreading models for Gnutella.  ...
