Offshore wind farms are increasing in size and moving further from shore. Service operation vessels (SOVs) are used for offshore wind operation and maintenance (O&M) at these large far offshore sites. These large vessels typically have a smaller daughter craft (DC) on board that can assist them. This DC is however too small to provide the...

In the conceptual design phase, OEMs perform technology assessment to identify feasible solutions for their new aircraft. When the OEM is unable to assess a certain technology themselves, they consult Tier-1 suppliers to involve<br/>them in the design process. The suppliers have higher fidelity analysis tools that can help the OEM with their...

The offshore wind market is rapidly growing, resulting in increasing wind turbine sizes, increasing distances to port, and a shift to deeper waters. A literature study in this thesis shows that existing wind turbine installation vessels, vessels under construction, and innovative concepts will not be able to install next-generation turbines or...

Boundary layer ingestion is an airframe-propulsion integration technology capable of enhancing aircraft propulsive efficiency. The Propulsive Fuselage Concept, a tube-and-wing layout with an rear-fuselage-mounted propulsor in the boundary layer ingestion configuration, especially takes advantage this. However, the relation between physical shape...

This article examines the potential implications of using iron powder as an alternative fuel on the design and performance of container ships. Iron powder is a relatively new alternative energy carrier and one in which little research has been done into the application on-board vessels as part of the maritime energy transition. The key...

Modern High Level Synthesis (HLS) tools succeed well in their engineering productivity goal, but still require toolset and target technology specific modifications to the source code to guide the process towards an efficient implementation. Furthermore, their end result is a fixed function accelerator with limited field and runtime...

The design space of power plants of naval surface vessels is ever expanding. As a result, the design space has become too large for a human design team to fully explore. Therefore, a concept exploration tool is introduced to generate and evaluate all possible concepts within the design space. An optimal solution is chosen based on ship...

Aircraft maintenance design aims to identify strategies that render the aircraft reliable for flight in a cost-efficient manner. These are often conflicting objectives. Moreover, existing studies on maintenance design often limit themselves to only one type of maintenance strategy, overlooking other potentially dominating designs. We propose...

With an increasing complexity of systems, systematic design space exploration is required for fair analysis and comparison of architecture design options. However, there is still a need for a benchmark problem to support the development &amp; evaluation of optimization algorithms and system architecture design space modeling methods, and to...

Quantum algorithms can be expressed as quantum circuits when the circuit model of computation is adopted. Such a circuit description is usually hardware-agnostic, that is, it does not consider the limitations that the quantum hardware might have. In order to make quantum algorithms executable on quantum devices they need to comply to their...

As a move away from the natural gas based heating, the Dutch government identified district heating networks as most economical alternative to the natural gas. However, the future plans for the district heating sector have faced challenge on the question of the design of heat market and management of factors such as ownership, network access,...

Datacenter infrastructure has become vital for stakeholders across industry, academia and government. To operate efficiently, datacenter operators rely on a variety of complex scheduling techniques, to distribute user workloads across resources. In this work, we leverage a reference architecture for datacenter scheduling to design and implement...

This research aims to help in solving problems experienced with system integration in early-stage ship and system design by enabling automated design space exploration for on-board energy distribution systems. An Automatic Topology Generation (ATG) tool is developed and tested to do so. The ATG tool supports system designers in making trade-off...

In this thesis, we present Cprof+, an upgraded version of Cprof. Cprof+ is a lightweight profiling tool for Polyhedral Process Networks (PPN) that can estimate the performance of a C-program as a PPN implemented in hardware. Cprof+ improves the set of possible programs that can be successfully profiled, by increasing the performance estimation...

Preliminary ship design (or early stage design in US terminology) is the very first step in designing a new ship. In this stage ship designers attempt to find an affordable balance of the future owner's (customer or operator) ambitions and operational needs. This balance is then translated into more tangible design requirements. However, the...

Turboprop aircraft achieve higher propulsive efficiencies at lower speeds due to their engine’s ability to accelerate a high mass flow of air at low jet velocities. With the increased importance of environmental considerations in aircraft design, aircraft manufacturers are forced to open up the considered speed domain since a reduction in cruise...

Designers are confronted with high time-to-market pressure and an increasing demand for computational power. As a result, they are required to identify as early as possible the quality of a specification for an intended technology. The designer needs to know if this specification can be improved, and at what cost. Specification trade-offs are...

Until recently, design teams were constrained by tools and schedule to only be able to generate a few alternatives, and analyze these from just a few perspectives. The rapid emergence of performance-based design, analysis, and optimization tools gives design teams the ability to construct and analyze far larger design spaces more quickly. This...

HEALTHCARE in the 21st century is changing rapidly. In advanced countries, in particular, healthcare is moving from a public to a more personalized nature. However, the costs of healthcare worldwide are increasing every year. Better use of technology can and should be used to get control of these costs. At the same time, implants have clearly...
