Every day an extremely large amount of messages get sent over the internet, radio, WiFi, etc. These messages need to be encoded in order to protect the important data. However just like many of these systems messages can get corrupted over a certain channel due to noise, fluctuations in power or temperature etc. [2] Therefore cyclic redundancy...

The four-colour conjecture (4CC) is a question that asks whether any map can be coloured using only four colours, with the constraint that neighboring countries must have distinct colours. This conjecture has re- mained unanswered for over 170 years, with a rich history of various attempts to prove it. In 1879, Kempe put forward a proof, but it...

The world can’t keep up with its own data and therefore needs new ways to store it. Research is being done into new types of experimental data storage like DNA sampling or racetrack memory, which could completely revolutionize the way storage works. However, such storage media are prone to certain type of errors like deletion errors where...

Coding techniques for correcting combinations of deletion, insertion and substitution errors are implemented in novel data storage applications. Error correcting codes have been well-studied for either substitution errors, or deletion and insertion (indel) errors, but the understanding of codes that correct combinations of...

While the Minimum Euclidean Distance detection is known to be optimal for channels affected by Gaussian noise, it has been shown that Minimum Pearson Distance detection (MPD) may perform better when the channel is also affected by an unknown offset, though for a good performance some adaptations for classical binary block codes are necessary. It...

Nowadays, we produce an enormous amount of data and all this data needs to be stored somewhere. In order to store all this data in an efficient and environmentally friendly way, solutions need to be found. A storage technique that has great potential to be a solution is synthetic DNA based storage.<br/>A DNA-strand is made up of a sequence of...

Humanity is producing data at exponential rates. Solutions need to be found in order to accommodate the bytes of today and the future in an efficient and environmentally friendly way. DeoxyriboNucleic Acid, well-known as DNA, is a suitable destination for this major collection of data, as it is a high-density storage medium with long storage...

This thesis aimed to aid ErasmusMC in the workforce planning process of deciding how to implement training among the nursing personnel in order to build a more flexible workforce, so the hospital can be prepared for fluctuating and unexpected demand, while minimizing the costs of doing so.<br/><br/>To accomplish this, a mathematical model was...

The amount of data being produced is growing exponentially. An im-<br/>portant challenge is to find methods to store this data efficiently and in an<br/>environmentally friendly way. One idea that is a growing research topic in-<br/>volves using synthetic DNA. DNA has the potential to be more efficient and<br/>environmentally friendly than...

Flash calculations are used for the dynamic simulation of vapor-liquid phase equilibria (VLE) in many chemical processes. When used to predict the composition of mixtures in VLE, the repeated applicatino of these flash calculations, particularly in dynamic cases can cause small inaccuracies to cascade. One way to prevent this, is to have strong...

Storage systems, such as Flash memories, suffer, apart from the always present<br/>noise, also from offset. The presence of this noise can decrease the performance<br/>of a decoder using the Euclidean distance significantly. To negate the effects of<br/>offset, a new distance, the modied Euclidean distance, was introduced, which<br/>offers...

It is predicted that in about 100 years most of the earth's fossil fuels will have been depleted. Currently, fossil fuels still make up 80% of the Dutch energy production. Thus, to handle this depletion, the research on renewable energy production and its usage is being stimulated by governments. With the use of fossil fuel energy production, it...

Indoor localization is a topic that has been investigated for more than a decade. Yet, no single system exists that is widely adopted as the de facto localization standard. From a research perspective the goal is to obtain a solution that is general, simple and accurate. As the number of devices in the Internet of Things grow, a new set of...

In this thesis, we investigate the maximum energy benefit of compute-and-forward applying on general networks. The energy benefit is defined as the ratio of the minimum energy consumption in network when a symbol is communicated successfully for every session when the network is in traditional routing mode, and the minimum energy consumption in...

In the field of Error Correcting Coding (ECC), the concept of ''stopping set'' recently became a hot topic. A stopping set for a parity-check matrix is the set of bits which would cause the iterative decoding progress in Binary Erasure Channel (BEC) to ''stop'' when it is erased. It has already been proved in several papers that the decoding...

Most decoding algorithms of linear codes, in general, are designed to correct or detect errors. However, many channels cause erasures in addition to errors. In principle, decoding over such channels can be accomplished by deleting the erased symbols and decoding the resulting vector with respect to a punctured code. For any given linear code and...

Prior work of network coding is mainly focusing on multicast traffic. In this thesis, we propose a new network coding based communication algorithm called Network Coded Flooding (NCF) which is related to network wide broadcast. This designed algorithm is an integration of network coding and one of the commonly used broadcasting techniques in...

A theoretical equation to calculate an estimation of the bit error floor of punctured turbo codes is discussed. Furthermore we calculate the coefficients needed for this equation for symmetric and asymmetric turbo codes of memory order 3 and 4 and for code rate 1/2, 3/5, 2/3, 7/10 and 3/4. This leads to the conclusion, that most of the times the...
