	abstract = {The Debian project is one of the largest free software undertakings worldwide. It is geographically distributed, and participation in the project is done on a voluntary basis, without a single formal employee or directly funded person. As we will explain, due to the nature of the project, its authentication needs are very strict{\textemdash}User/password schemes are way surpassed, and centralized trust management schemes such as PKI are not compatible with its distributed and flat organization; fully decentralized schemes such as the PGP Web of Trust are insuficient by themselves. The Debian project has solved this need by using what we termed a {\textquotedblleft}curated Web of Trust{\textquotedblright}.

We will explain some lessons learned from a massive key migration process that was triggered in 2014. We will present the social insight we have found from examining the relationships expressed as signatures in this curated Web of Trust, some recommendations on personal key-signing policies, and a statistical study and forecast on aging, refreshment and survival of project participants stemming from an analysis on their key-handling.},

	abstract = {Context: While industrial use of UML was studied intensely,little is known about UML use in Free/Open Source Soft-ware (FOSS) projects. Goal: We aim at systematically mining GitHub projects to answer the question when mod-els, if used, are created and updated throughout the whole project{\textquoteright}s life-span. Method: We present a semi-automated approach to collect UML stored in images, .xmi, and .uml files and scanned ten percent of all GitHub projects (1.24million). Our focus was on number and role of contributors that created/updated models and the time span during which this happened. Results: We identified and studied 21 316 UML diagrams within 3 295 projects. Conclusion: Creating/updating of UML happens most often during a very short phase at the project start. For 12\% of the models duplicates were found, which are in average spread across 1.88 projects. Finally, we contribute a list of GitHub projects that include UML files.},

In this present job, we seek to develop a prototype of an automated agricultural irrigation system, monitored and controlled remotely. For that, we will use inexpensive tools, flexibility and support such as Arduino, XBee and Android. Arduino and XBee, will be responsible of the automating the system. Android will achieve the remote monitoring and control from anywhere in the world where there is cellular service and Internet. In this way we can give the farmer the comfort and security that he don{\textquoteright}t get with a manually controlled system.
