Progressive age information should provide the age state that the system is in, and the rate that it is being aged at. In this paper, we propose a structure that monitors certain paths of a circuit and detects its gradual age growth, and provides the aging rate and aging state of the circuit. The proposed monitors are placed on a selected set of nodes that represent a timing bottleneck of the system. These monitors sample expected data on these nodes, and compare them with the expected values. The timing of sampling changes as the circuit ages and its delay increases. The timing of sampling will provide a measure of aging advancement of a circuit. To assess the efficacy of the proposed method and compare it with other state-of-the-art aging monitors, we use them on selected nodes of the execution unit of different processors, as well as some circuits from ITC99 benchmarks.

While discovering links between resources on the Web of Data has been shown to be a demanding task, discovering links between geo-spatial resources proves to be even more challenging. This is partly due to the resources being described by the means of vector geometry. Especially, discrepancies in granularity and error measurements across data sets render the selection of appropriate distance measures for geo-spatial resources difficult. In this paper, we survey existing literature for point-set measures that can be used to measure the similarity of vector geometries. We then present and evaluate the ten measures that we derived from literature. We evaluate these measures with respect to their time-efficiency and their robustness against discrepancies in measurement and in granularity. To this end, we use samples of real data sets of different granularity as input for our evaluation framework. The results obtained on three different data sets suggest that most distance approaches can be led to scale. Moreover, while some distance measures are significantly slower than other measures, distance measure based on means, surjections and sums of minimal distances are robust against the different types of discrepancies.}}, author = {{Sherif, Mohamed and Ngonga Ngomo, Axel-Cyrille}}, journal = {{Semantic Web Journal}}, keywords = {{2017 group\_aksw slipo sys:relevantFor:infai sys:relevantFor:bis ngonga simba DICE sherif geo-distance limes}}, title = {{{A Systematic Survey of Point Set Distance Measures for Link Discovery}}}, year = {{2017}}, } @inproceedings{29018, author = {{Sherif, Mohamed and Dreßler, Kevin and Ngonga Ngomo, Axel-Cyrille}}, booktitle = {{Proceedings of Ontology Matching Workshop 2017}}, keywords = {{2017 dice simba sherif radon ngonga slipo sage geiser hobbit group\_aksw sys:relevantFor:infai sys:relevantFor:bis limes linkinglod sake diesel kevin sys:relevantFor:leds leds}}, title = {{{RADON results for OAEI 2017}}}, year = {{2017}}, } @inproceedings{29030, abstract = {{Geospatial data is at the core of the Semantic Web, of which the largest knowledge base contains more than 30 billions facts.

WOMBAT is based on generalisation via an upward refinement operator to traverse the space of link specification. We study the theoretical characteristics of WOMBAT and evaluate it on 8 different benchmark datasets.
