Call me Ishmael: Using Dynamic Analysis to Hunt Whales on the Internet

Docker has been one of the most widely used DevOps tools in the last decade, enabling fast development of personalized services. Indeed, the common practice is to reuse already available containers and customize them based on the developer's needs. DockerHub is the leading platform for uploading and downloading Docker containers. Unfortunately,...

Quantifying suspended sediment using multi-frequency echosounder measurements: Assessing the potential of single instrument sediment concentration inversions that account for variations in particle size

Echosounders are used to monitor suspended sediment concentrations (SSC) in coastal management studies and to monitor dredge plumes. Due to the dependency on sediment properties like particle size, shape and density, performance of single frequency measurements is limited when sediment properties are changing.<br/><br/>Using multi-frequency...

Managing Efficiency on Euhydration measurements

The problem encountered by TIM Solutions was mainly based on experiences of their own in different hospitals. The project was therefore started with mapping the wishes of possibile users and mapping the current context. Already in the beginning it turned out that fluid balance measurements are well based estimations as not all aspects are being...

Frame Loss Characterisation and Data Erasure Coding for LoRaWAN

Internet of Things (IoT) solutions are increasingly being deployed for smart applications. With the rise of smart cities there is a need for low cost and long range Low Power Wide Area Network (LPWAN) technologies. LoRaWAN is an energy efficient and cheap LPWAN solution. It is rapidly being adopted all around the world. LoRaWAN however does not...

Remote sensing waves in data-scarce countries: An analyis of the wave climate along the myanmar coast

The objective of this thesis was analyzing and evaluating different sources of wave data. Wave data from two hindcasts, satellite altimetry and wave buoys were compared with each other in order to validate different data sets. These datasets provided to be useful tools in determining the wave climate along the coast of Myanmar.

Improvement of fatigue damage prediction for the Balder J-lay tower during transits

Heerema Marine Contractors (HMC) is a contractor that transports and installs large structures at sea. For this purpose, HMC operates four crane vessels of which three are semi-submersibles (Thialf, Balder and Hermod) and one is a mono hull (Aegir). The Balder is equipped with a J-lay tower for pipelay in deep water. During transits, when the...

Identification of response amplitude operators for ships based on full scale measurements

Heerema Marine Contractors (HMC) operates several crane vessels, barges and tug boats for the transportation, the installation and the removal of offshore facilities. To achieve safe and successful projects, the accurate prediction of vessel motions is of great importance. Vessel motions are calculated on the basis of wave energy spectra and...

Design of a controller for an adjustable frictionless resistance fitness device, with wireless user feedback

This report proposes a design for a control system for a variable frictionless resistance training device, that is able to set the resistance and give feedback to the user via a wireless connection. The fitness device uses regenerative braking and information about the generated power is sent back to the user. The variable resistance is set...

Developing a data based method to quantify the effects of flight track, aircraft weight and engine setting on the received aircraft noise levels

Airports in The Netherlands are subjected to tangent environmental laws to restrain pollution and noise nuisance. Amsterdam Airport Schiphol (AAS) is one airport dealing with this regulatory framework but nevertheless they are resolute to continue growth with respect to aircraft movements. To cope with the law related to aircraft noise, the...

NoSQL spatial: Neo4j versus PostGIS

The relational data model is now more than 40 years old. It's good for very diferent scenarios and can handle certain types of data very well. But it isn't perfect. An increasing number of non-relational systems are being worked on, collectively called the 'NoSQL movement'. NoSQL is an umbrella term for a loosely defined class of non-relational...

Wideband channel measurements at 60 GHz in different environments

For future mobile multimedia communication, a Mobile Broadband System is in development, which operates at a frequency of 60 GHz. In order to get a better understanding of 60 GHz propagation effects in different environments with different conditions, several measurements were performed, using a spectrum analyzer and synthesized signal generator...
