Cost Estimation for Factorized Machine Learning

In the realm of machine learning (ML), the need for efficiency in training processes is paramount. The conventional first step in an ML workflow involves collecting data from various sources and merging them into a single table, a process known as materialization, which can introduce inefficiencies caused by redundant data. Factorized ML strives...

Cost Estimation for Factorized Machine Learning in Data Integration Scenarios

The workflow of a data science practitioner includes gathering information from different sources and applying machine learning (ML) models. Such dispersed information can be combined through a process known as Data Integration (DI), which defines relations between entities and attributes. When all information is combined in one source suited...

Machining cost estimation in topology optimization for 2.5-axis CNC milling: Adapting a new-school design method to an old-school manufacturing process

The work presented in this report is an attempt to allow density-based topology optimization algorithms to take into account machining costs when optimizing. To this end, and estimation model for the cost of 2.5-axis CNC milling was developed based on the principles of Design for Manufacturing.<br/>This estimation model was implemented in a...

Aircraft bi-level life cycle cost estimation

n an integrated aircraft design and analysis practice, Life Cycle Cost (LCC) is essential for decision making. The LCC of an aircraft is ordinarily partially estimated by emphasizing a specific cost type. However, an overview of the LCC including design and development cost, production cost, operating cost and disposal cost is not provided. This...

A building cost estimation method for inland ships

There is very little publicly available data about the building cost of inland ships, especially for ships that have dimensions that differ significantly from those of common ships. Also, no methods to determine the building cost of inland ships are described in literature. In this paper, a method to estimate the building cost of inland ships is...

Study on Sedimentation and Effects of Mitigating Measures at Port of Mar del Plata, Argentina

Problem definition The city Mar del Plata has one of Argentina's largest ports and biggest seaside beach resort. After the construction of the port, a steadily growing sandbank appeared in the port entrance and considerable erosion occurred on the northern beaches. To warrant the accessibility of the port, frequent maintenance dredging is needed...

Multidisciplinary Design and Optimization Framework for Aircraft Box Structures

Competitive aircraft box structures are a perfect compromise between weight and price. The conceptual design process of these structures is a typical Multidisciplinary Design and Optimization effort, normally conducted by human engineers. The iterative nature of MDO turns development into a long and costly process. Knowledge-Based Engineering...

Analysis of costs in new terminals investments

This thesis studies cost estimation and investment decisions under cost uncertainty of large construction projects. The combination of these two topics intends to satisfy the Master’s theses of Civil Engineering at the Delft University of Technology and Quantitative Finance (Econometrics) at the Erasmus University Rotterdam. The first part...

Analytical cost estimation for embedded systems

In the today's market of microcontrollers and FPGAs, there are so much different makes and models that making the right choice for a hardware platform for an electronics design is impossible. The spectrum is so wide that an electronics designer is unable to make a good choice for the best microcontroller or FPGA for his/her design based on the...

Evaluatie van ramingsstijgingen bij tunnels en aquaducten: Het verantwoord omgaan met onzekerheden in ramingen en budgetten

In het verleden is gebleken, dat de door Rijkswaterstaat gemaakte ramingen tijdens de levensloop van een project (van voorfase tot realisering) een stijgende tendens vertoonden. Mede op verzoek van de Tweede Kamer heeft het Ministerie van Verkeer en Waterstaat een onderzoek verricht naar de oorzaken van deze ramingsstijgingen. Op basis van de...
