Design of a Performance Benchmarker for Fully Distributed IaaS Clouds

Nerdalize B.V. is an infrastructure-as-a-service (IaaS) cloud provider aiming to offer substantially lower prices than its competitors. In order to visualize its cost savings to customers and measure its own systems against competitors in a cloud market reigned by opaque pricing models, it would like to utilize an application benchmarker to give...

Distributed-Dynamic State Estimation with SCADA and PMU

The purpose of this research is mainly to develop a distributed dynamic state estimation with PMU and SCADA as a response of the challenges in state estimation problems (accuracy, computational time, the use of new technology along with the ability to keep the existing traditional measurement). With the implementation of statistical signal...

Hardware acceleration of simulations of distributed systems

In recent years the study of complex systems gained prominence. Since it is usually difficult to use classical mathematic models to understand these systems, scientists and engineers have to resort to simulations. Currently programming languages like CUDA C and OpenCL are available to run large scale simulations on a GPU architecture....

Transparency in actions on requirements

The combination between agile software engineering and distributed engineering is gaining a growing interest. Combining these however creates an interesting paradox. Where agile clearly states that documentation is not the most important thing, from the field of globally distributed engineering a higher focus on documentation is observed. In...

Maximum Power Point Tracking Topology, sensor and switch design

The Nuna 6 is a solar racing vehicle that solely relies on solar energy from the sun. Every year, the team seeks ways to improve the performance of their car. One way to improve the performance is to maximize the power output of the solar panels on top of the car. Maximizing the power output can be done with a 'Maximum Power Point Tracker'. The...

Finding faulty components in a dynamic distributed system at runtime

This document describes the research performed on fault isolation in dynamic distributed systems at runtime. An existing Spectrum-based Multiple Fault Localization approach is used as the basis for fault isolation, but is adapted and optimized so it can be used for online diagnosis. The result is an algorithm, coined AIMBACH, which finds the...

Run-time Reconfiguration in Wireless Sensor Networks

A wireless sensor network (WSN) consists of multiple small and simple computers (nodes), whose performance is tightly linked to its unpredictable deployment environment. It is nearly impossible to design a WSN that performs well in every scenario; instead they are developed for a specific context, with performance rapidly decreasing when...

Swarm Discovery in Tribler using 2-Hop TorrentSmell

Peer-to-peer (P2P) technology allows us to create self-organising and scalable systems. The distributed nature of these systems requires a solution for finding interesting peers. In the context of P2P file sharing, finding peers who are downloading the same file is referred to as the swarm discovery problem. In BitTorrent, this problem is solved...

Distributed Map Construction

Assume that two sub-graphs of a graph are available and that the graph represents the corridors in a building. Without using any previous knowledge on the entire graph, can these two sub-graphs be used to construct an extended view on the entire graph. To test this assumption a collection of algorithms will be designed and implemented which can...

Customer Involvement in Distributed Requirements Engineering

The graduation project is run as an internship at software company Exact. The company wants to reduce the time to market for their products. To achieve this objective, Exact wants to adopt agile development and is aiming towards the implementation of a development process that is both globally distributed and Scrum-like. The project’s goal in...

Globally Distributed Agile Release Trains

SAFe is a framework that applies both agile and lean practices for developing software. The current trend is that increasingly more organizations develop their software in a globally distributed setting. Although SAFe is being deployed in such a setting, SAFe was not originally developed for such a setting but for a co-located setting. Therefore...
