Tagus: an IoT data ingestion pipeline for MonetDB

Dissertação de mestrado integrado em Engenharia InformáticaIn this project, we design and implement an IoT streaming data ingestion pipeline for MonetDB, using the distributed message queueing platform Apache Kafka. Our objective is to leverage MonetDB’s analytical power for IoT data, expanding its ingestion capabilities to improve reliability and performance. The ingestion pipeline is put to the test with the real world maritime tracking system AIS. We also evaluate MonetDB’s current IoT processing engine and compare it to other state-of-the-art engines, to appraise its functionalities and identify possible future improvements.Neste projecto, conceptualizamos e implementamos uma pipeline para ingestão de dados streaming para o sistema de base de dados MonetDB, utilizando o Apache Kafka, uma plataforma para message queueing distribuído. O nosso objectivo é utilizar o poder analítico do MonetDB para dados IoT, expandindo as suas capacidades e melhorando a confiabilidade e desempenho na ingestão de dados streaming. A pipeline é posta à prova com o sistema de tracking marítimo AIS, demonstrando a sua aplicabilidade no mundo real. As funcionalidades de processamento de dados IoT do MonetDB são avaliadas e comparadas com outras plataformas de última geração para identificar desenvolvimentos futuros

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved
