Bin there, target that: Analyzing the target selection of IoT vulnerabilities in malware binaries

For years, attackers have exploited vulnerabilities in Internet of Things (IoT) devices. Previous research has examined target selection in cybercrime, but there has been little investigation into the factors that influence target selection in attacks on IoT. This study aims to better understand how attackers choose their targets by analyzing...

Dynamic analysis of Android applications to extract spam caller IDs

Spam calls are becoming an increasing problem, with people receiving multiple spam calls per month on average. Multiple Android applications exist that are able to detect spam calls and display a warning or block such calls. Little is known however on how these applications work and what numbers they block.<br/>In this research, the following...

Analysing Android Spam Call Applications: Developing a Methodology For Dynamic Analysis

The aim of this research is to provide a structured approach for dynamically analysing Android applications, focusing on applications that block or flag suspected spam caller IDs. This paper discusses ways to determine how an application stores the data regarding the phone numbers, and what APIs it utilizes. In order to develop a methodology of...

Dynamic analysis and characterization of a desorption column for a continuous air capture process

The world is currently in the middle of an energy crisis, with a growing demand for energy playing catch up with an increasing population. The problem stems from the fact that we rely heavily on fossil fuels to meet our energy needs, and the combustion of these fuels are the primary source of greenhouse gas emissions. An accelerated rate of...

Creating a local residual curvature during S-lay pipeline installation by lowering the stinger

Marine pipelines are often operated at high internal pressure and temperature. This loading condition results in the development of axial compressive forces that can cause the pipeline to buckle globally. Global buckling occurs when significant lateral motion is present in the pipeline and excessive feed-in occurs at that specific location,...

Authorship Attribution of Malware Binaries

Attribution of the malware to the developers writing the malware is an important factor in cybercrime investigative work. Clustering together not only malware of the same family, but also inter-family malware relations together provides more information about the authors and aid further malware analysis work. In this report, previous work which...

Concrete slab beneath ballast bed - An Abatement Measure For Railway Induced Vibration

In this research project, an assessment of an abatement measure for mitigating railway induced vibrations is carried out. Ground-borne vibrations, which are primarily generated due to wheel-rail interaction, may also result in ground-borne noise in the buildings located in vicinity of railway tracks. An example of adverse environmental impact...

Dynamic electrical behaviour of a solar powered methanol micro-plant

Liquid fuels are projected to account for 88% of total energy use in the transportation sector in 2040. Low cost of renewable energy poses a new opportunity for decarbonisation of the transport sector. As a liquid en- ergy carrier, methanol offers a promising solution for alternative fuels in aviation, shipping and long-distance trucking. Zero...

Practical Engineering Design Tool for Vibration Sensitive Laboratory Building Structures: Development of a practical design tool based on a scientific model for an early design of vibration sensitive laboratory building structures excited by traffic induced vibrations for use in engineering practice

The prediction of structural vibrations in vibration sensitive laboratory structures is a complex problem involving computationally heavy 3D models with long computational times. However, in the early design phases of a project long computational times are undesirable. Therefore the problem statement of this Master thesis concerns the...

Non-linear dynamic response of a beam using an impulse response method based on linear complex modes

The purpose of this thesis is to formulate and test a computational method, based on linear complex modes, to calculate the dynamic response of a beam with a boundary dashpot excited by a non-linear response-dependent dissipative force. This impulse response method is a time-stepping method which iteratively approximates the non-linear force by...

Modelling and dynamic analyses of TLP-type floating wind turbine

Fixed support structures for offshore wind turbines are commonly used for shallow water (till 45 meters). In many countries shallow-waters are rare. Floating support structures may be the solution for these areas. Many concepts have been developed but three concepts have been analyzed (spar, semi-submergible and the tension leg platform (TLP))...

The dynamic response of a Hyperloop tube embedded in soft soils

The hyperloop system is a new transportation mode, which consists a magnetic levitating capsule-like hyperloop pod and a vacuum tube. Due to small air hindrance, the hyperloop pod is conceived to have a maximum speed of 333 m/s. If such a hyperloop system is to be built underground in soft soils, the hyperloop speed can easily reach the wave...

Dynamic analysis of two innovative tuned mass damper systems for a wind turbine using a 2-DOF model

Reducing the cost of constructing wind turbines, as well as extending their design life, are two ways of reducing the cost of energy from wind. To achieve this, this project tested two innovative tuned-mass damper systems, which reduce resonance of the tower, and do so minimizing additional mass needed on the nacelle. These TMD systems allow the...

Modelling, control and stability analysis of the COBRAcable project integrated in the Dutch transmission system: Evaluation of the performance of the controllers

The COBRAcable project is one of the major interconnectors being constructed in the North Sea, connecting the Netherlands with Denmark. It is a 325 km submarine cable which will have the ability to transfer 700 MW. The importance of the interconnector is manifold: to facilitate the exchange of renewable energy coming from the onshore Danish...

Structural integrity assessment of self-elevating units with fatigue and corrosion damage based on actual load history

Seafox owns and operates a fleet of 12 Jack-ups. The design life of these Jack-ups is typically around 30 years. However, some have remained operational after exceeding their design life. It is therefore critical to gain an understanding how long and under what conditions these jacks-ups are still able to operate safely. There are two main...

Hierarchical Abstraction of Execution Traces for Program Comprehension

Understanding the dynamic behavior of a software system is one of the most important and time-consuming tasks for today’s software maintainers. In practice, understanding the inner workings of software requires studying the source code and documentation and inserting logging code to map high-level descriptions of the program behavior with low...

Simplified Fatigue Assessment of Offshore Wind Turbine Full Height Lattice Structures in the Frequency Domain

New concepts for support structures of offshore wind turbines have gained interest in the industry and are examined for intermediate and deep water depths in order to unlock new offshore potential markets. One of the main proposals that has already been commercialized is the three or four leg full height lattice structure. The fatigue assessment...

Field Of Threads: Master’s Thesis on a tool for clarifying thread behavior

Multithreaded programming is becoming increasingly important because of recent increase in the use of multiprocessor computing. Multithreaded or concurrent programming is inherently more complex than single threaded code, requiring the use of synchronization and causing possible problems like deadlock or dormancy. Dynamic analysis tools can aid...
