Architecture framework in support of effort estimation of legacy systems modernization towards a SOA environment

Because of their poor Business/IT alignment, many legacy systems lack the flexibility to support rapid changes to the business processes they implement, required by today's enterprises. Furthermore, after many years of maintenance, there is a need to manage their resulting increased complexity and maximize asset utilization through reuse. The...

Trade-off Analysis between Security and Efficiency of Airport Operations: A methodological underpinned modelling approach to identify, analyse and evaluate trade-offs based on empirical choice observations

This Master Thesis document presents a research on trade-off analysis between security and efficiency factors during airport operations. Over the past few decades there has been an increase in security in the air transportation industry, with even more measures taken since 9/11. Besides affecting the operational costs of airports, the stricter...

Modelling and analysis of dynamic relations and trade-offs between security and efficiency in airport security operations

The two performance areas “security” and “efficiency” in airport security operations cannot be analyzed apart from each other, since influencing one has a large impact on the other. In this research agent-based modelling is used to analyze dynamic relations and trade-offs between security and efficiency within airport security operations....

Scrutinizing Consumer-Citizen Duality Towards Safety and Travel Time Trade-Offs: A Case Study of On-Demand Motorbike Taxi in Jakarta

Capturing the individual’s behavioral responses to the actions driven by market and government will always be an interesting activity towards a broad spectrum of society. It could not be neglected that an individual may have different views in responding towards a new policy intervention or a new product market. However, references to use of the...

Accuracy-efficiency trade-off for using event-based data when performing bounding box-based object detection

Event-based cameras do not capture frames like an RGB camera, only data from pixels that detect a change in light intensity, making it a better alternative for processing videos. The sparse data acquired from event-based video only captures movement in an asynchronous way. In this paper an evaluation is made on the efficiency and accuracy of...

Exploring Trade-offs in Reservoir Operations through Many Objective Optimisation: Case of Nile River Basin

Water storage and diversion capacity of reservoirs in the Nile Basin are benefited for various purposes including agricultural irrigation and hydro-energy production. Filling and operation of the recently constructed Grand Ethiopian Renaissance Dam (GERD) have been subject to heated debate for its implications on downstream countries Sudan and...

Concept design for floating offshore wind turbine installation with the Pioneering Spirit: A systems engineering approach

Due to the growing demand for offshore wind energy and the increasing wind turbine sizes, a shortage of capable installation vessels is anticipated by 2024. Consequently, the utilisation of heavy-lift vessels, previously not employed for bottom-founded or floating offshore wind turbine installations, may become imperative to realise the offshore...

Exploring distributive justice in water resource allocation: A rival framings approach on the operationalization of equality in multi-objective optimization models for water systems

Water, an essential resource for diverse purposes like environmental protection, urban water supply, energy generation, and agriculture, faces intensifying demand amid depleting supplies. Multi-Objective Optimization (MOO)-models are vital for addressing complex water system challenges with limited resources. However, varying approaches to...

Hydrogen Peroxide as an Oxidiser for Medium-Lift Launch Vehicles: A Performance and Integration Analysis

Cryogenic and semi-cryogenic propellants are the most commonly used liquid propellants for applications in medium-lift launch vehicles. Despite their high performance, the storage requirements for these propellants often lead to complex, heavy, and voluminous structures. The only storable propellant used in medium-lift launch vehicles, UDMH/NTO,...

The application of reusable hollow core slab connections in steel frames: Investigating the behaviour of a newly proposed reusable connection with increased tolerances

To align with the objective of the European Green Deal [46] policy of achieving net-zero greenhouse gas emissions by 2050, the construction sector must transition to a circular built environment. Most of the waste in the Netherlands is related to construction and demolition waste, with the industry accounting for approximately 35% of CO<sub>2<...
