Efficient Testing of Recovery Code Using Fault Injection

George Candea, Paul Dan Marinescu

A critical part of developing a reliable software system is testing its recovery code. This code is traditionally difficult to test in the lab, and, in the field, it rarely gets to run; yet, when it does run, it must execute flawlessly in order to recover ...

Byzantine agreement with homonyms

Rachid Guerraoui, Anne-Marie Kermarrec, Eric Ruppert

So far, the distributed computing community has either assumed that all the processes of a distributed system have distinct identifiers or, more rarely, that the processes are anonymous and have no identifiers. These are two extremes of the same general mo ...

Computational modeling of face-to-face social interaction using nonverbal behavioral cues

Dinesh Babu Jayagopi

The computational modeling of face-to-face interactions using nonverbal behavioral cues is an emerging and relevant problem in social computing. In the thesis, we have investigated individual social constructs in small groups such as dominance and status ( ...

Dissent: Accountable Group Anonymity

Bryan Alexander Ford, Henry Nathaniel Corrigan-Gibbs

Users often wish to participate in online groups anonymously, but misbehaving users may abuse this anonymity to disrupt the group. Messaging protocols such as Mix-nets and DC-nets leave online groups vulnerable to denial-of-service and Sybil attacks, while ...

Cell Phones as Imaging Sensors

Sabine Süsstrunk, Joanna Marguier, Jérôme Berclaz

Camera phones are ubiquitous, and consumers have been adopting them faster than any other technology in modern history. When connected to a network, though, they are capable of more than just picture taking: Suddenly, they gain access to the power of the c ...

Image-Based Mobile Service: Automatic Text Extraction and Translation

Jérôme Berclaz

We present a new mobile service for the translation of text from images taken by consumer-grade cell-phone cameras. Such capability represents a new paradigm for users where a simple image provides the basis for a service. The ubiquity and ease of use of c ...

On degraded two-message set broadcast

Christina Fragouli, Suhas Diggavi, Vinod Malathidevi Prabhakaran, Shirin Saeedi Bidokhti

We consider the two message set problem, where a source broadcasts a common message W1 to an arbitrary set of receivers U and a private message W2 to a subset of the receivers P ⊆U . Transmissions occur over linear deterministic channels. For the case wher ...

Interference Alignment at Finite SNR: General Message Sets

Michael Christoph Gastpar

Interference alignment has proven to be a powerful tool in characterizing the high SNR behavior of wireless networks. Using this technique, Cadambe and Jafar showed that the sum degrees-of-freedom for the K-user interference channel is K/2 rather than 1 as ...

On Degraded Two Message Set Broadcast

Christina Fragouli, Suhas Diggavi, Vinod Malathidevi Prabhakaran, Shirin Saeedi Bidokhti

We consider the two message set problem, where a source broadcasts a common message

W_1

to an arbitrary set of receivers

\mathcal{U}

and a private message

W_2

to a subset of the receivers

\mathcal{P}\subseteq \mathcal{U}

. Transmissions occur over l ...

Social Software Modeling and Mashup based on Actors, Activities and Assets

Denis Gillet, Christophe Salzmann, Evgeny Bogdanov

Despite the extreme diversity of Web applications, one can find similarities among them. This paper proposes an answer to the question of knowing whether it is possible to conceptually represent different Web applications in a common manner such that they ...
