This work evaluates a standardized 30-ton, 16 m railbus platform optimized for unelectrified regional service, focusing on propulsion system design and trade-offs between range, cost, and emissions. A MATLAB/Simulink drive-cycle model was developed to simulate energy consumption and component performance under realistic operating conditions. The Erfurt–Rennsteig route in Germany (130 km round trip
With the widespread deployment of convolutional neural networks (CNNs) at the edge, on-device fine-tuning has become essential for real-time model adaptation to address environmental accuracy degradation. However, on-device training is constrained by the "memory wall" energy bottleneck and numerical instability from low-precision fixed-point arithmetic. To tackle these challenges, this t
Fire incidents involving Li-ion batteries is an increasing concern as the use of battery electric vehicles is increasing. Abuse conditions such as heating can result in ejection of flammable and toxic gases, presenting a health risk and risk of explosion or fire. The purpose of the present work is to increase the understanding of combustion of gas mixtures vented from Li-ion batteries. The investi
Fuel cells are promising due to advantages with higher energy conversion efficiency and lower emissions of SOX, NOX and CO2 than conventional power systems. Solid oxide fuel cell (SOFC) is a high temperature fuel cell, which operates at 600-1000 ºC. The high operating temperature and the anode material allow SOFCs to operate with different types of fuels from both fossil and renewable sources due

This paper is an attempt to link the concept of Existential Sustainability to research within the field of electrical power systems modelling. This is specifically done in the context of electrification and the energy transition. In extension, this implies a connection between the fields of humanities and technology.

A general approach to the modifications of the spectrum of a laser pulse interacting with matter is elaborated and used for spectral diagnostics of laser wakefield generation in guiding structures. Analytical predictions of the laser frequency red shift due to the wakefield excited in a capillary waveguide are confirmed by self-consistent modeling results. The role of ionization blue shift, and no
The Port of Rotterdam is an important industrial cluster mainly comprising of oil refining, chemical manufacturing and power and steam generation. In 2015, the area accounted for 18 % of the Netherlands' total CO2 emissions. The Port of Rotterdam Authority is aware that the port's economy is heavily exposed to future global and EU decarbonization policies, as the bulk of its activities focuses on
It is expected that fuel cells will play a significant role in a future sustainable energy system. They are energy efficient, fuel can be produced nearly locally and, when a renewable fuel such as ethanol, methanol and biogas is used, there are no net emissions of greenhouse gases. Fuel cells have during recent years various progresses, but the technology is still in the early phases of developmen
Access to reliable and affordable electricity remains a significant challenge in many rural regions of Sub-Saharan Africa. This thesis presents a feasibility study for the implementation of a solar-powered mini-grid in Linga Linga, a rural village in the Inhambane province of Mozambique. Conducted in collaboration with the non-governmental organization Project Vita, the study focuses on Section B
Diesel engines are one of the most important power generating units these days. Increasing greenhouse gas emissions level and the need for energy security has prompted increasing research into alternative fuels for diesel engines. Biodiesel is the most popular amongst the alternatives for diesel fuel as it is biodegradable, renewable and can be produced domestically from vegetable oils. In recent
The MAX laboratory at Lund University, Sweden, today operates an accelerator system consisting of a 100 MeV racetrack microtron and a 550 MeV storage ring (MAX I). At the moment (July 1994) a new storage ring MAX II is near completion and will start first injections within 2 months. This work gives an overview of the MAX II project including the first beamlines and a description of the accelerator

I takt med att hållbarhet blir viktigare söker många företag inom jordbrukssektorn lösningar för att fasa ut fossila drivmedel. Utmaningen blir ännu mer komplex när ersättningen ska vara kompatibel med en existerande fordonsflotta, utan investering i nya fordon. Denna studie jämförde fyra kommersiellt tillgängliga och förnybara drivmedel med referensbränslet diesel. De undersökta drivmedlen är HVAs sustainability becomes more important in today's society, many companies in the agricultural sector are looking for new alternatives to fossil fuels. The challenge becomes even more complex when the replacement must be compatible with an existing vehicle fleet, without requiring new investments in vehicles. This report compares four commercially available and renewable fuels, using convent
