During recent years the increasing power of computers has led to the use of more sophisticated analysis tools within the mechanical engineering design process, or design process for short. Projects whose objective has been to introduce the Finite Element (FE) analysis into the early phases of the design process have been carried out at the Department of Machine Design, see e.g. [1]. These works cl

Recent years has seen an unprecedented growth in emerging technologies like Additive manufacturing (AM), augmenting the manufacturing capabilities through a multitude of opportunities while also introducing unique constraints, such as support structures, and post-processing requirements. Taking full advantage of the potential of AM demands product designs to be optimised for both opportunities and

The increase in contact resistance within battery systems remains poorly understood, despite being one of the primary contributors to battery degradation. This project aims to investigate this phenomenon by modeling the electrical interface as a contact between a pin and a busbar. The main goal is to build a DOE and machine learning framework, using Bayesian optimization to efficiently explore the

The S.T.A.R. Design Studio (Space and Terrestrial Architectural Research) studies pre-industrial habitats in i.a. Tanzania, and develops design concepts for future habitats in space in cooperation with Johnson Space Centre, Houston, Texas. In both cases our studies focus on "extreme" circumstances. Perhaps studying the conditions of a crew sealed in a capsule can better prepare us for the problems

With an increasing awareness of environmentalism, the transportation sector is also understanding its duty to protect the natural resources given to humankind. For the sector it is increasingly important to decrease the weight of transportation vehicles to save fuel and electrical energy. For a severe weight reduction Volvo Buses plans to launch a lighter bus structure in the coming years. This in

Biosensors are powerful analytical tools, but their wider application is limited by the natural repertoire of available biological recognition elements. Allosteric transcription factors (aTFs) are attractive scaffolds for expanding this repertoire, but redesigning them to detect novel ligands has historically relied on directed evolution and structure-guided rational design, approaches that are la

This chapter presents a simulation model for the optimization of a reservoir system that is being developed. Simulation studies were carried out, firstly to determine the best (and by how much) irrigation facilities to provide in the proposed new scheme, and secondly, to see the applicability of simulation in reservoir planning. A computer simulation model using MATLAB has been developed to analyz

The EU aims to be a circular economy by 2050, which is the driving force behind this master thesis. Circular transformation is one possible strategy to handle the climate crisis and achieve sustainable development. A circular economy is a system that aims to keep the value of products, materials, and resources in use as long as possible while minimising waste generation (Svenskt Näringsliv, 202

Being one of the poorest countries in the world in UN’s Human Development Ranking, Mozambique struggles with both poverty and malnutrition. This runs counter to the fact that Mozambique is a country rich in natural resources with a great supply of crops. Research has shown that the lack of preserving methods within the agricultural field is a contributing factor that strongly affects the countries

This thesis describes the development of a safety system for a mobile robotic cell for an autonomous grinding machine. The utilization of autonomous construction equipment presents the opportunity to streamline construction processes and save time and money. This entails the development of sufficient safety equipment lowering the risk of accidents. The goals of the project are the identification o

Antibody-based microarrays are among the new, rapidly emerging technologies within the field of proteomics that has the potential to evolve into a key proteomic research tool, providing novel means to perform early diagnostics, identify biomarkers and gain insights into disease biology. The aim of this thesis, based on five original papers, was to develop antibody microarrays based on human recom

The FFT processor is used for OFDM-based UWB wireless communication system. 64/128 points FFT is employed in the processor by using mixed-radix algorithm to meet the requirement of different UWB systems. The FFT processor, using the pipelined parallel structure, the register reusing architecture and the shift-add algorithm, can reach a device utilization of 100% and a 500MS/s throughput rate(FPGA
