The number of personal computers we use every day has increased significantly the last couple of years, where the common model is a setup where each device has its own storage with separate files and applications. This forces the user to think in a certain way about files and applications, where they are to a degree bound to a device unless the user specifically moves the files, or installs/uninstalls ...

Existing networked filesystems are usually either client/server - allowing storage only on one node - hard to use, or both. The advanced ones also like to use their own on-disk format, complicating migration both ways. Skynet attempts to remedy this. It is a distributed filesystem with master/slave redundancy that is easy to use, relatively safe for your data and can be easily converted to/from ...

Secure multiparty computation (SMC) is a technique that allows multiple parties to jointly compute a function while keeping their inputs private. This technique has gained significant attention due to its potential applications in various fields, including privacy-preserving healthcare, politics and finance. SMC involves a set of protocols that enable parties to achieve secure computation and ...

It is estimated that computers and mobile devices use more than 2% of the total energy consumed. That means a lot of energy is going in powering our cpu,display and gpu. In this paper we are trying to optimize the power consumed by cpu in partitioned global address space environment. Recent research suggests that there is scope in improving cpu power usage by having a better scheduler. Simhadri ...

This dissertation studies composing a super sensor network from the combination of three functional sensor networks; A Sensor data producing network, a sensor data computing network and a sensor controlling network. The target devices are today labeled as large sensor nodes. The communication are based on an IP network using HTTP as the main protocol. Bonjour is used for service discovery, with ...

I dag er elektronisk post en naturlig måte å kommunisere på. Dessverre er det enkelte brukergrupper som ikke kan utnytte denne teknologien. Vårt fokus er barn i alderen 4-8 år. Symbo prosjektet tar sikte på å gi disse brukerne muligheten til nettopp dette. Målet med dette prosjektet er å lage et symbolbasert språk kalt SymboL. Dette er en samling symboler som gjennom bruk gir et begrenset ...

This master’s thesis evaluates the scalability and cost-effectiveness of the AWS cloud platform used to collect and utilize data generated by the 87 digitally equipped trams. The SL-18 Cloud Platform was developed before the trams arrived, and resource configuration estimates were made to handle the data generated by the trams. However, with a few trams currently operational, it is crucial to evaluate ...

The amount of content available for consumption online is increasing tremendously. This make the job of recommender systems more important, and at the same time, more demanding. Context-aware recommender systems might be a solution to this problem. This work set out to discover user contexts dynamically by collecting contextual information from user actions and perform cluster analysis on the ...

To achieve low overhead, traditional cluster monitoring systems sample data at low frequencies and with coarse granularity. However, interactive monitoring requires frequent (up to 60 Hz) sampling of fine-grained data and visualization tools that can explore and display data in near real-time. This makes traditional cluster monitoring systems unsuited for interactive monitoring of distributed cluster ...
