We study the possibility that the Milky Ways' cool stellar disk includes mergers with ancient stars. Galaxies are understood to form in a hierarchical manner, where smaller (proto-)galaxies merge into larger ones. Stars in galaxies, like the Milky Way, contain in their motions and elemental abundance tracers of past events and can be used to disentangle merger remnants from stars that formed in th
The snowmelt at a point is estimated through a simplified energy budget. From the energy equation a degree-day method is derived. The rate of snowmelt isfound as a constant multiplied by the temperature excess over an equilibrium temperature which depends on solar radiation.The snowmelt events in Kiruna (3 years) and LuleH (4 years) are analysed utilizing energy balance computations and the degree
The use of aluminum-magnesium (Al-Mg) alloy particle as energetic additive in solid propellants was previously shown to have many advantages over pure Al particle, such as relatively low ignition temperature, high reaction rate and low particle agglomeration rate. In this paper, the combustion of Al-Mg alloy in hot H2O/O2/N2 flows was experimentally studied using wires with a diameter of 200 µm. T
In the present paper we consider the problem of attitude synchronization for a system of rigid body agents. We provide distributed kinematic control laws for two different synchronization problems. In the two problems the objective is the same, i.e., to synchronize the orientations of the agents, but what is assumed to be measurable by the agents differs. In problem 1 the agents measure their own
Characteristic modes of arbitrary 2-D periodic systems are analyzed using scattering parameter data. This approach bypasses the need for periodic integral equations and allows for characteristic modes to be computed from generic simulation or measurement data. Example calculations demonstrate the efficacy of the method through comparison against a periodic method of moments (MoM) formulation for a
Internet has made information more easy to get, but also more difficult to retrieve. There is a need for information retrieval systems that assure accurate, reliable and up to date information. Quite a number of both commercial and non commercial search services has been developed on the Internet. We have made a qualitative study of one for-pay product in particular, NetS k, produced by BTJ (Bibli
During this bachelor thesis a first version of a digital tool has been formed. The tool is uniquely developed for the company Tirawa Solutions AB whose main task is to plan inspections of different railway track parts all across Sweden. The main purpose of this thesis is to investigate what functionalities are interesting to achieve a system that can display information about railway switches and
Att Spåra Gammastrålar med en Gammakamera Gammastrålar produceras av både radioaktiva material och kosmiska objekt, så som supernovor och neutronstjärnor. Gammastrålar består av fotoner, precis som synligt ljus, men har mycket högre energi. Att kunna spåra gammastrålar är användbart inom allt från medicinteknik, till samhällsskydd, och även inom många olika forskningsområden. Fotoner kan interagIn this study the Geant4 toolkit has been used to perform Monte Carlo simulations of relatively inexpensive, inorganic, scintillator-based detectors. Full simulations of the optical photons produced via the scintillation process have been done in order to achieve realistic responses from the attached electro-optical sensors. The main focus of this work is on identifying interaction positions in sc
This thesis interrogates Rome’s housing cooperative sector, focusing on the challenges and opportunities housing cooperatives face in providing affordable housing for their members. It analyses Rome’s housing regime to present the housing context in which housing cooperatives operate. The thesis explores what housing affordability means within the eternal city, moving beyond a simple income ratio

Bibliometrics is the quantitative measurements of scientific publications. It is increasingly used for the evaluation of research and the allocation of research funds. On this page you will find useful links and information about journal ranking, H-index and citation analysis. Support on bibliometrics At LUSEM Library, we provide support on the citation databases such as Web of Science and Scopus,
Project HAIDI The project Demography and Democracy – Healthy Ageing in a Digital World (HAIDI) addresses two critical challenges for the Nordic countries and their ageing population: digitalisation and health development. The purpose is to provide new knowledge to counteract health disparities related to the changing demographic patterns and neutralize digital divides threatening inclusion and dem

professor, physioterapist Research area: Exercise is good for your joints! My research is mainly targeted at young to middle-aged people who are at an increased risk of sustaining a knee or hip injury or who have an existing injury. A joint injury can result in joint pain, functional instability, physical inactivity, and poor quality of life. It also increases the risk of sustaining new injuries a

Summary Electron spectroscopy has provided much of our current knowledge on the chemical and physical processes involved in the complex interactions between a solid surface and its surroundings. Such processes are for example important for surface catalysis, corrosion and thin film growth.As the surface state depends strongly on its environment, it is vital that such studies are performed under re

Årskurs: 7-9, Gymnasiet Ämnesområde: Kraft och rörelse Med en hårfön eller genom att blåsa själv kan man sänka lufttrycket och ofta på ett spektakulärt vis påverka olika föremål i enlighet med Bernoullis princip. Vi ägnar därför två filmer till att tipsa om en rad experiment på temat blåsningar. Vad är Bernoullis princip? Bernoullis princip säger att trycket i en strömmande vätska eller gas sjunk
