We use a train of sub-200 attosecond extreme ultraviolet (XUV) pulses with energies just above the ionization threshold in argon to create a train of temporally localized electron wave packets. We study the energy transfer from a strong infrared (IR) laser field to the ionized electrons as a function of the delay between the XUV and IR fields. When the wave packets are born at the zero crossings o
This paper concerns propagation of transient electromagnetic waves in laterally discontinuous dispersive media. The approach, used here, employs a component decomposition of all fields. Specifically, the propagation operator that maps a transverse field on one plane to another plane is specified. Expansion of this mapping near the wave front determines the precursor or forerunner of the problem.

Brand activism has emerged as a prevalent phenomenon where brands engage in socio-political issues to differentiate themselves and build stakeholder resonance. Despite its growing prominence, research on brand activism is limited, particularly in relation to brand positioning. Thus, the purpose of this study is to explore how a newly launched brand engaging in socio-political agendas communicates
Today, many projects about Electric Vehicles (EVs) and Hybrid Electric Vehicles (HEVs) are in progress within the automotive industry. Fuel-efficiency and reduction of carbon dioxide emissions from vehicles are the main targets. This thesis is within in one of these projects that is called electric All Wheel Drive(eAWD) at BorgWarner TorqTransfer Systems AB. A key parameter to perform an accurate
Sensing technologies offer several advantages for industrial tooling. In mechanical processing and manufacturing environments, sensors can be used to monitor process conditions, support predictive maintenance, reduce unnecessary material losses, and improve overall production efficiency. Therefore, as manufacturing systems become more advanced and data-driven, the integration of sensors has become
The purpose of this paper is to investigate the potential of complex or exotic materials in radome and antenna design. The existing analysis methods need to be extended to cope with these materials in generic radome and antenna geometries. This paper focuses on electromagnetic properties of the material, the means of realizations, and the methods of computations. The main objectives of this paper
Italian professor of automatic control and expert in nonlinear and hybrid system control theory and the applications to traffic control, smart grids, and biological systems (b. 1953) Maria Domenica Di Benedetto is an Italian engineer and professor of automatic control. She is mainly known for her advances in the science of nonlinear and hybrid system control theory and its many applications to tra
We examine how the generation and propagation of high-order harmonics in a partly ionized gas medium affect their strength and synchronization. The temporal properties of the resulting attosecond pulses generated in long gas targets can be significantly influenced by macroscopic effects, in particular by the intensity in the medium and the degree of ionization which control the dispersion. Under s
A fundamental problem in robotics is generating the motion for a task. How to translate a task to motion or a series of movements is a non-trivial problem. The complexity of the task, the structure of the robot, and the desired performance determine the sequence of movements, the path, and the course of motion as a function of time, namely the trajectory. As we discuss in this thesis, a trajectory
This paper describes searches for the pair production of first or second generation scalar leptoquarks using 35 pb(-1) of proton-proton collision data recorded by the ATLAS detector at root s = 7 TeV. Leptoquarks are searched in events with two oppositely-charged muons or electrons and at least two jets, and in events with one muon or electron, missing transverse momentum and at least two jets. Af
The Department of Architecture and Built Environment has four third-cycle study programmes: Architecture, Construction and Architecture, Environmental Psychology and Architecture leading to a degree of Doctor of Philosophy in Fine Arts ArchitectureIn the third-cycle subject Architecture, the significance of spatial planning for the relationship between humans and the built environment is examined.

Most deterioration processes in cement based materials are closely related to moisture sorption and moisture transport properties. Therefore, it is important to study these properties, both theoretically and practically. This work is an experimental investigation in this field. Nowadays, the cement industry produces cements with increasing amounts of supplementary cementitious materials (SCMs) to

The article introduces a framework for understanding women's entry into the academic world and how it interacts with internal departmental structures and practices. It presents three specific strategies applied by a group of women to gain a doctorate and acceptance in their department. Few previous studies have stressed women's strategies to cope with the organizational setting in academia. The ar
Background: Quality of supervision is a major predictor for successful PhD projects. A survey showed that almost all PhD students in the Health Sciences in Denmark indicated that good supervision was important for the completion of their PhD study. Interestingly, approximately half of the students who withdrew from their program had experienced insufficient supervision. This led the Research Educa
