Nanowires can act as efficient light absorbers where waveguide modes are resonant to specific wavelengths. This resonant wavelength can easily be tuned by the nanowire dimensions, but the absorption of infrared radiation requires diameters of hundreds of nm, which is difficult to achieve using epitaxial growth. Here, we demonstrate that infrared absorption in InAsSb nanowires with the diameters of

We present a non-resonant, dual band circular polarization selective structure (CPSS) for satellite communication applications in the K- and Ka-band. The structure consists of multiple layers of cascaded anisotropic sheets, with printed meander lines, separated by low permittivity spacers. It reflects right hand circular polarization and transmits left hand circular polarization in the lower freque

3D-printad protesarm för ökad individanpassning och komfort Målet med en protes är att återställa så många funktioner som möjligt från en förlorad kroppsdel och skapa en naturlig känsla för användaren. Detta har vi jobbat mot i vårt examensarbete och med hjälp av både 3D-printerns och 3D-scannerns unika möjligheter har vi skapat en individanpassad och kroppsstyrd armprotes. Den enkla protesen är 3D printing, or additive manufacturing, is a technology that uses a digital model to print a three-dimensional object, layer by layer. Today, it is widely used in many different fields and provides a manufacturing method with advantages such as precision and the ability to print complex shapes from many different materials. 3D printed prostheses have recently gained a lot of interest thanks to the

The aim of this study is to investigate human behavior during the pre-movement phase of building evacuation and determine how pre-movement time varies between different building types and types of alarms. Unannounced videorecorded evacuation experiments from earlier studies were examined, which resulted in 2 486 individual pre-movement times divided amongst six different building types. The parts

Today, it seems as if every second designed object is referred to as timeless design. We use the word timeless as a selling word without really thinking about what it means. Through investigating the concept of timeless design, I found the physical paper book being probably one of our most timeless objects. There are tons of book storing furnitures on the market of which the majority consists of

Modelica-TM is an object-oriented language for modeling physical systems that was designed in the last years with the goal to become a standardized multi-domain modeling language. This paper describes a robust model for homogenous and inhomogenous two phase flows with dynamic or static slip correlation. It was developed in the context of developing a Modelica base library for thermo-hydraulic appl

Open source software is becoming more common in software development today and constitutes an increasing share in modern web applications. Open source has many benefits; it is cost-effective and increases development speed, quality, and security. With the advent of open source, companies and organizations have taken many different initiatives to minimize the risks of open source, disseminate knowl

This thesis aims to investigate and implement a fault-tolerant energy-efficient RISC-V based system on chip (SoC). Key features of the SoC is the testabil- ity and reliability of the low power on-chip embedded memories. A built-in self- test (BIST) for the on-chip memories has been designed and implemented to run on-demand diagnostic tests to detect manufacturing errors in the memories. It incor

En järnväg kommer till en ort som tidigare saknat tågtrafik. En station ska byggas och passas in i en befintlig struktur. Nya möjligheter till att pendla skapas, till arbetsplatser och utbildning på andra orter. Fler får också möjlighet att besöka orten tack vare järnvägen. Under järnvägsbyggandets guldålder för drygt 100 år sedan kunde orter få en enorm tillväxt tack vara den nya förbindelsen ochThe places close to where a new railway line and new stations are established, are hugely affected by the arrival of this new mode of transportation. New possibilities to travel further in the same time as before, or the same distance in half the time, significantly increases the opportunities for both commuting and for visiting places. Historically, new villages or even towns have sprung up as

Effectively utilizing Big Data can be a challenge for many companies. Due to its volume, many aspects of the data processing pipeline such as storage, retrieval and usage may quickly become problematic. For example, it could be difficult identifying the relevant metrics when analyzing a service failure. Visualizing and deriving insights from the data could also prove to be quite onerous. Immersive

Sedan den 1 juli 2018 bygger våldtäktslagstiftningen i Sverige på frivillig-het, eller samtycke, som det kallas i både facklitteratur och populärkultur. Detta innebär att det som numera ligger i fokus är gärningsmannens uppsåt till det faktum att den andra personen inte deltar frivilligt i en sexuell handling. En annan förändring som gjordes vid införandet av den nya lag-stiftningen var att våldtäIn 2018, Sweden passed a new law regarding rape, which is based on the lack of voluntary participation or in other words, consent. This means that it is now the perpetrators intent, regarding that the other person does not participate voluntarily in the sexual act, which lays in the court judgements focus. Another change was that a new offense where passed, negligent rape. Thus, criminal liability

Games regarding money can be seen as entertainment and a thrill in life. However, gambling can also lead to financial difficulties when it develops into an addiction. The Swedish National Board of Health and Welfare equates gambling addiction with other addictions such as alcohol and tobacco. The marketing of tobacco and alcohol is restrictively regulated by law, unlike the marketing of games. The

The rapidly increasing use of AI-chatbots creates ever evolving questions of privacy concerns in end users where they have to evaluate where the line is drawn between personalization and privacy intrusion. The conducted literature review highlights the complex landscape of privacy theories, privacy concerns and human-AI interactions. Using this as a guide, a qualitative study has been conducted on

In many IBA applications the main aim is to obtain quantitative figures characterizing the sample. Normally charge, i.e. number of probe particles, is used for normalization and is measured either by collecting the charge deposited in the sample or by collecting the particle in a post-sample Faraday cup or in combination. Both these techniques have drawbacks and results can be difficult to compare

This thesis examines the blog ‘Alla Dessa Dagar’ by the Swedish Minister of Foreign Affairs Carl Bildt; one of the pioneer politicians using social media to broadcast political messages. Based on role theory and theories covering social media, with capacities of democratization and blurring between public and private, the focus of the study is twofold. To begin with the study aims to identify how

This thesis was constructed between January 8:th and May 30:th in the year 2009 at Lund institute of technology. This will be the master’s thesis of the Master of Science programme in mechanical engineering at Lund institute of technology. Light weight designs are becoming more and more important in the world today. As composite materials are being improved via research, it is possible to repl

This paper examines the consequences of the US transition from a T+2 to a T+1 settlement cycle. We assess whether the reform enhanced market liquidity, increased settlement frictions, and whether effects varied across firm types and time horizons. Using a Difference-in-Differences design with matched US–EU firm-level data, we evaluate short-, mid-, and long-term impacts on three liquidity proxies:

This thesis is structured around one central question: This study will determine the extent to which political change in the discourse topics of European Political Groups (EPGs) can be traced in European election manifestos through the use of Structural Topic Modeling (STM). This thesis asserts that there is a significant gap in our understanding of how to assess Euromanifestos and of the macrostr

In the software industry, the drive to add new features often overshadows the need to improve existing code. Large Language Models (LLMs) offer a new approach to improving codebases at an unprecedented scale through AI-assisted refactoring. However, LLMs come with inherent risks such as braking changes and the introduction of security vulnerabilities. We advocate for encapsulating the interaction
