Cell Concentration Sensor for micro-bioreactors: Optical sensor system

This bachelor thesis describes the development of a sensor system for measuring the cell concentration in small bio-reactors. The study was conducted at Delft University of Technology on behalf of Applikon Biotechnology B.V. The MicroMatrix of Applikon is used for experimental determination of the optimal conditions for bioprocesses in...

Cell Concentration Sensor for Micro-Bioreactors: Impedance Sensor

This thesis describes a bachelor graduation project of the study Electrical Engineering at Delft University of Technology. The purpose of this project is to develop an impedance sensor that can measure the cell concentration in a micro-bioreactor. This bioreactor will be used to investigate the optimal cell growth conditions of a cell culture....

Cell Concentration Sensor for Micro-Bioreactors: Software & Data Processing

This thesis was written for the bachelor’s final project, of the study Electrical Engineering. It describes the design of a cell concentration sensor. A proof of concept was designed which is able tomeasure the cell concentration of yeast in a suspension by using sensors which measure the impedance and optical properties of the suspension. The...

World Hydropower Capacity Evaluation

A continuous population growth and increasing energy demand combined with depleting traditional energy reserves puts a pressure on conventional methods of electricity generation. The desire and ambition to create a more sustainable society paves the way for the ‘renewables’. Hydropower or Hydroelectricity already plays a significant role in...

Project Sensory room: From isolation to interaction

In the psychiatry, isolation cells are used to lock up patients, when they become emotionally instable, behave aggressively and become a danger towards their selves or his environment. The isolation cell is a low stimulus and high safety environment. This means simply put that the patient has no control in the room. He is dependent on the staff...

Implementation of Nexus: Dynamic Hardware Management Support for Multicore Platforms

Current trends in computer architecture focus on multicore platforms. The target of these new platforms is to scale the performance of the system with the number of cores. However, the performance of current archictectures is limited due to thread-level parallelism overhead and programmability. StarSS is a task-based programming model that eases...

IWEX: Mapping on current high performance architectures

IWEX stands for Invers Wavefield Extrapolation and is commonly used in seismic exploration. Niels Pörtzgen[15] showed that this technique can also be used for inspection of welds. This thesis describes two domains in which the IWEX algorithm can be calculated. The time domain which has a quantization problem and the frequency domain which is...

Stability of morphological cells to dredging-dumping activities

The Westerschelde estuary in the South-West of the Netherlands displays two meandering flood and ebb channels separated by shoals. The system of flood, ebb channel and shoal between two channel crossings form a morphological cell. The stability of the serial cell system formed by the Westerschelde is important for the navigation route to the...
