The Multipath TCP (MPTCP) protocol allows applications to better explore the network resources available to multi-connected devices such as mobile phones or multi-homed systems. Here, some advantages are envisioned: bandwidth ...

The rapid popularization of smartphones has contributed to the growth of SMS usage as an alternative way of communication. The increasing number of users, along with the trust they inherently have in their devices, makes ...

The easy access to mobile and social networking is changing the way people communicate; however, the deaf person is segregated in some of these media. Although there are many designers working with some recommendations, ...

No clustering algorithm is guaranteed to find actual groups in any dataset. To deal with this problem, many techniques apply various clustering algorithms to a dataset, generating a set of partitions and assessing them to ...

This work proposes both a study and a development of an algorithm for super-resolution of digital images using projections onto convex sets. The method is based on a classic algorithm for spatial super-resolution which ...

The goal of this study is to investigate the characteristics of the new data clustering approaches, carrying out a comparative study of clustering techniques that combine or select multiple solutions, analyzing these latest ...

Due to the widespread adoption of distributed systems when building applications, demand for reliability and availability has increased. These properties can be achieved through replication techniques using algorithms that ...

The Smart City (SC) concept aims to promote dynamic and flexible systems to the cities, that interact with each others and help to maintain the stability and scalability of it’s resources and services, usually through ...

The main theme of this dissertation are the k-flow-critical graphs, which are graphs that do not have a k-flow but once any two vertices (either adjacent or not) are identified the smaller graph thus obtained has a k-flow. ...

Nowadays smartphones are composed of a wide range of sensors and resources such as GPS (Global Positioning System), Bluetooth and Internet connection through Wi-Fi, 3G, among others resources. Along with the smartphone’s ...
