Application of the seeding approach to nucleation in a CaO-SiO₂ system for obtaining the parameters for the Classical Nucleation Theory: A valuable numerical tool for screening potential glassmaking recipes

For the use of screening potential glassmaking recipes the seeding method has been applied to a Molecular Dynamics simulated CaO-SiO₂ system in order to attain the parameters for the Classical Nucleation Theory and construct a Time-Temperature-Transformation (TTT) diagram. Using this TTT diagram, the non-crystallisation temperature and the...

UV-C LED Seed Disinfection: Mechanics Group

This thesis presents the design and development of a UV-C LED-based seed treatment machine aimed at enhancing seed quality by the extermination of pathogens. The research covers design choices, including a round irradiation pattern, consisting of two rings with three and nine LEDs for the inner and outer ring respectively, the use of a quartz...

UVC Seed Sterilization BSc Thesis: Software and Control

In this thesis for the Bachelor’s Degree in Electrical Engineering, a Control Unit (PCB and software) is designed for inside the UVC Seed Disinfection Machine of Team UVO. The machine consists of four modules: the Control Unit, the LED Driver, the motor controller and the power supply. The Control Unit allows a user to input the intensity per...

High-Level Mutations for JSON Typed Data in Big Data Fuzz Testing

Fuzzing in Big Data applications is a relatively new field which is still lacking effective tools to support automated testing. Recently, a framework called BigFuzz was published which made fuzz testing for big data systems feasible. But there was no solution to work with Big Data programs that use JSON typed data. Big Data systems often make...

The QIEM-Array: An Innovative Seed Germination Apparatus

The constantly growing world population has en ever-increasing food supply demand. With the decreasing quality of available agricultural land, innovations in the agricultural sector will play an increasingly crucial role. Increasing productivity, improving quality and increasing the nutritional values of the end products are key in combating the...

Towards bottom-up fabrication of a BDD chip electrode

Boron-doped diamond (BDD) is an attractive electrode material. When sufficiently boron-doped, diamond has metal-like conductivity and in comparison with other electrode materials has several advantages, such as lowand stable background current, reduced biofouling, broad potentialwindow, corrosion resistance and chemical stability. However,...

Improving Test Case Generation for RESTful APIs through Seeded Sampling

To validate the quality of software, test cases are used. These test cases are often manually-written, which is labor-intensive. To avoid this problem, automated software testing was invented. Search-based software testing is a useful tool for developers to automatically generate test cases. However, improvements are still needed to create test...

University funding instruments: an assessment of the Delft Enterprises case study

Is Equity Crowdfunding for you?: An assessment tool for high-tech start-up entrepreneurs & recommendations to platforms

Many start-ups face difficulty raising sufficient funds at the early stage of their businesses. Traditionally, entrepreneurs raise capital from friends and family, angel investment, venture capital or bank loans. However, with the development of Internet platforms, alternative finance methods have arisen. Entrepreneurs are starting to look for...

Modeling the single seed oxygen consumption of germinating seeds

The rate of oxygen consumption by germinating seeds is considered to be one of the promising parameters for monitoring the seed status and a candidate for predicting germination and seed vigor. Nowadays, the single seed oxygen consumption patterns can be measured on a big scale and at a detailed time resolution using a Q2 machine. However,...

Influence of Seed Surface Pre-Processing on Crystal Growth Behavior in Cooling Batch Crystallization

Product quality and yield of pharmaceuticals produced by traditional industrial seeded batch cooling crystallization-operations is subject to large fluctuations as a consequence of seed surface quality. In this research, effects of seed pre-treatment by dry- and wet-milling were investigated on subsequent performance in crystallization behavior...

South Chicago House of Jazz

Development of 'seed-planning' style of urban planning, and the design for a house for music and popular culture in South Chicago.

An X-ray tomographic investigation into the effects of compressive shear on analogues to charred seeds embedded in archaeological sand

By signing the Valletta Treaty, several countries have obliged themselves to save archaeological heritage sites and fund relevant research. UNDERSTRESS is a proposal for funding which does research and provides data to predict damage done to such archaeological site by construction of linear infrastructure. As a preliminary study this BSc thesis...

The behaviour of artificial archaeological remains during a one-dimensional compression test

The Dutch subsoil contains a lot of archaeological remains that need to be preserved for future generations. Until now, it is not possible to predict if these remains will stay intact under the pressure of a manmade structure like an embankment. The goal of this research is to investigate the behaviour of assemblies of artificial archaeological...

Grinded Dutch calcite as seeding material in the pellet softening process

Calcium carbonate pellets are produced as a by-product in the softening process. In The Netherlands, these pellets are applied as a raw material in several industrial and agricultural processes. The sand grain inside the pellet hinders the application in some high potential market segments such as paper and glass. Earlier work showed that it is...

Incentivizing Seeding In BitTorrent - Indirect Interaction as an Incentive to Seed

BitTorrent has turned into the most popular P2P file sharing protocol and is used for various purposes such as Video on demand and Media Streaming. The fundamental problem with P2P networks in general is that quality of service highly depends on altruistic resource sharing by participating peers. Many peers freeride on the good intentions of...

Tribler Download Core Improvement

BitTorrent is a popular peer-to-peer file sharing protocol. From a user’s perspective, it is important that a BitTorrent client downloads the files as fast as possible. The socially enhanced BitTorrent client called Tribler – from the Delft University of Technology and the Vrije Universiteit – was presumed to be lacking in speed. This...
