Current Instant Messaging systems rely on architectures that include central, or only partly distributed, server(s). Although some systems can exchange messages peer-to-peer, the user registration and lookup are still based on a centralized solution. We have implemented a fully distributed instant messaging system by utilizing the Pastry peer-to-peer routing substrate. We use the Pastry object ...

“Pan de Muerto” is a traditional bread type, emblematic of Mexican bakery. This work’s objectives were defining its characteristics, determining the effect fat content, and storage conditions on staling, examining relative impact these crystallization starch retrogradation. Staling was evaluated via changes in Young’s modulus. Fat retrogradation studied considering thermal crystalline propertie...

Overlay networks are widely used for locating and disseminating information by means of custom routing and forwarding on top of an underlying network. Distributed Hash Table (DHT) based overlays in particular, provide good scalability and load balancing properties. However, these come at the cost of inefficient routing, caused by the lack of adaptation to the underlying network, as DHTs often o...
