Exploring the potential of iron powder as fuel on the design and performance of container ships

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...

AEx: Automated High-Level Synthesis of Compiler Programmable Co-Processors

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...

Multi-objective design of aircraft maintenance using Gaussian process learning and adaptive sampling

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...

On Structured Design Space Exploration for Mapping of Quantum Algorithms

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...

On early-stage design of vital distribution systems on board ships

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...

Interactive evolutionary concept exploration in preliminary ship design

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...

A Case Study in Teaching Construction of Building Design Spaces

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...

Universal Processor Architecture for Biomedical Implants: The SiMS Project

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...

System-Level Design Space Exploration of Reconfigurable Architectures

Recon?gurable architectures are becoming increasingly popular as they bear a promise of combining the ?exibility of software with the performance of hardware. Nevertheless, such architectures are subject to numerous constraints, such as performance, memory requirements, chip area, and power consumption. To create an efficient design, performing...

Automated Design of Application-Specific Smart Camera Architectures

Parallel heterogeneous multiprocessor systems are often shunned in embedded system design, not only because of their design complexity but because of the programming burden. Programs for such systems are architecture-dependent: the application developer needs architecture-specific knowledge to implement his algorithms, as each processor has its...

Power-aware architecting for data-dominated applications

Chip designers face increasingly complex designs and multiple competing design objectives and constraints. Early in the design cycle, a designer has to make choices relying on insufficient or inaccurate information. For instance, the designer has to decide which parts to implement in software and which in hardware. The complexity of the designs...
