A new optical interferometer for delay stabilization in attosecond pump/probe experiments is constructed, featuring a custom-made hole-drilled recombination mirror and using a co-propagating HeNe laser for the interference. The interferometer is shown to generate an interference pattern of high enough contrast for delay stabilization. The stability of the measured delay is tested with the interfer
This paper examines the standing of private firms in the post-privatization economic reform in China regarding their access to human capital. The cross-sectional dataset used to test the model is extracted from the World Bank 2012 Enterprise Survey. Using a sample of 2848 Chinese firms of diverse ownership types, the paper studies the effect of firm ownership on human capital, and further studies
Happiness is a relatively new discipline within economics. Traditionally, economists have not paid too much attention to it since they considered that both indicators and theoretical assumptions in which this discipline was based were not neither reliable nor useful for policy recommendations. However, especially in the last decade, there has been extensive research which, if not proved, at least
CO2 Catalysis has been studied with Planar Laser Induced Fluorescence (PLIF) in combination with a mass spectrometer for a small, 23 cubic centimeters, cube shaped flow reactor. Both catalysis processes with one and with two catalysts inside the reactor have been carried out and analysed. Some results have been visualised by images showing concentration, given by the PLIF signal, of CO2 inside the
The phase field method emerged as a tool to solve free boundary problems with a sharp interface. In previous methods, this involved the computationally inefficient and complicated tracking of a moving interface. The phase field method overcomes this limitation by introducing an auxiliary variable called the order parameter which varies continuously over the whole domain and takes on finite values
Despite the increased focus on sustainable urban development both within academia and in urban planning practices, authors seem to agree that we are mostly continuing business as usual and are not embarking on different socio-environmental trajectories. On the contrary, such urban sustainability practices can often lead to processes of displacement and gentrification, thus worsening the conditions
När man jobbar med stora pogrammeringsprojekt är ett av de stora problemen att skriva koden så den går att underhålla. Skriver man kod som är lätt att underhålla är det också enklare att göra tillägg, ändringar och åtgärda problem. I detta projekt har två stora, liknande projekt undersökts för hitta likheter i koden. Om likheterna kan sammanföras till en generisk lösning kommer koden att vara lätWhen working with large programming projects, one of the major problems is to write the code so it can be maintained. If you write code that is easy to maintain it is also easier to extend, change and fix bugs in the code. In this project two large, similar projects were investigated to find similarities in the code. If the similarities could be brought together in a generic solution, the code wo
Non-stationary signals are very common in nature, consider for example speech, music or heart rate. Using the concept of time-frequency analysis this thesis studies the performance of different time-frequency distributions of both simulated and real non-stationary signals. The signals studied are linear and non-linear frequency modulated (FM) signals. Two methods are studied to increase performanc
Traffic accidents cause over 1.2 million deaths, and tens of millions of people are injured or disabled every year. Advanced driver assistant systems and other safety features have the possibility to reduce traffic accidents but do not account for human errors. Studies show that over 90% of all traffic accidents are caused by human errors. One way to reduce human errors is to introduce automation,
The aim of this study is to examine how counselors working in child - and adolescent psychology assert their professional knowledge and expertise in their everyday w ork and in their teams. Previous research has described an increase of medicalization in child - and adolescent psychology and this has affected counselors’ position s within the organization. The psychosocial aspect has reduced and c
A problem within the mobile instustry today is creating third-party applications. Generally developer teams have to develop the same application for several platforms and each platform uses a specific native language. A result of this is that many applications both look and act similar; but have different code bases and work very differently beneath the surface. This is a double maintenance prob
The present study examined the effect of manipulated (threatened or affirmed) sense of agency on Swedish students’ preference for leadership, by ease of retrieval. Three hundred and twelve students (Mage = 23.04, SD = 2.70) participated in the experiment. The aim of the study was to investigate whether individuals’ leadership preferences was affected by perceived sense of agency. By contrasting a
Methyl ammonium lead halides (MAPbX3 , X=Cl-, Br-,I-), crystallizing in a perovskite structure, have in recent years been shown to be a promising material as a light harvesting material in solar cells. It has many interesting properties which makes it suitable for solar cell applications, such as near-optimal band gap and long electron-hole diffusion lengths, as well as the possibility of synthesi
The Modelica language is an object-oriented, equation-based language used for modeling and design in many different domains and for various physical applications. In order to exchange models both between Modelicabased tools and other tools the Functional Mock-up Interface (FMI) has emerged. This interface enables exchange of virtual models between manufacturers and/or divisions within a company. T
El Niño and the Southern Oscillation (ENSO) have a great impact on global climate, often with disas-trous effects in many parts of the world. The carbonate skeleton of corals record El Niño activity by tracing sea surface temperature and salinity in the oceans where they grow. As El Niño’s core region is the equatorial Pacific Ocean, this is where the most direct consequences of ENSO are seen, com
One of the topics that has generated discussions and focuses on demographic theory is undoubtedly the treatment of fertility rates, another important number of studies have incorporated different methods for measuring behaviors in count data, such as Poisson models, also used in the present document. On the other hand, by using panel data, we estimate a random effects model and evaluate the dete
Industrial society is the reason for the rising global ecological crisis, and companies are a primary contributor to this trend. To change this course, companies must transform along with society’s green transition. In the academic debate of economics and sustainability, various competing economic paradigms suggest how to steer society towards a sustainable transformation. Based on theoretical his
Size Exclusion Chromatography (SEC) is a crucial analytical tool employed by Novo Nordisk for the assessment of potential aggregation in active pharmaceutical ingredients (API) derived from peptides and protein biopharmaceuticals. This investigation focuses on SEC analyses conducted under denaturing conditions, utilizing Ultra High-Performance Liquid Chromatography (HULK) adapted columns. Intrigui
