1. 6. A theoretical study of longitudinal and transverse spin fluctuations in disordered Fe64Ni36 alloys

   University essay from Linköpings universitet/Teoretisk Fysik

   Author : Amanda Ehn; [2020]
   Keywords : INVAR effect; longitudinal spin fluctuations; transversal spin fluctuations;

   Abstract : That certain iron and nickel alloys exhibit an anomalously low thermal expansion of a wide temperature range has been observed since late 1800s, and this effect is known as the Invar effect. Since then, many theories have been proposed to explain the phenomenon. READ MORE

3. 7. Dynamic Analysis of an Automotive Power Transfer unit : Towards prediction of TE and housing vibrations

   University essay from KTH/Maskinkonstruktion (Avd.)

   Author : Nikhil Maharshi Kosaraju; [2019]
   Keywords : Power transfer unit PTU ; Multi-Body Simulation MBS ; Transmission Error; Gear NoiseVibration; Modal Analysis; Vinkelväxlen PTU ; Multi-Body Simulering MBS ; transmissionsfel TE ; Växelljud och vibrationer; Modal analys;

   Abstract : This work describes the use of Multi-Body Simulation (MBS) to create a virtual prototype of a geared drive called Power transfer unit (PTU). PTU is a subsystem of the all-wheel drive driveline responsible for transfer of power between front and rear axles in an Automobile. READ MORE

4. 8. On the use of integer and fractional flexible Fourier form Dickey-Fuller unit root tests

   University essay from Lunds universitet/Nationalekonomiska institutionen

   Author : Marcus Nordström; [2018]
   Keywords : Fractional frequency flexible Fourier form; Unit root test; Structural break; Smooth break; Nonlinear trend; Business and Economics;

   Abstract : In this paper we propose the use of a new set of conservative critical values for the flexible Fourier form Dickey-Fuller unit root test when the Fourier frequency is estimated. We consider both the integer frequency and the fractional frequency version of the test and investigate their size and power properties. READ MORE

5. 9. Change Point Detection and Kernel Ridge Regression for Trend Analysis on Financial Data

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : David Petersson; Emil Backman; [2018]
   Keywords : ;

6. 10. Finite Element Analysis of the Dynamic Effect of Soil-Structure Interaction of Portal Frame Bridges - A Parametric Study

   University essay from KTH/Bro- och stålbyggnad

   Author : Turgay Dagdelen; Shaho Ruhani; [2018]
   Keywords : Soil-Structure Interaction; Railway Bridge; Portal Frame Bridge; Dynamic Analysis; Parametric Study; Nonlinear Analysis; Jord-struktur interaktion; Järnvägsbro; Plattrambro; Dynamisk analys; Parametrisk studie; Icke-linjär analys;

   Abstract : In Sweden, the railway sector currently faces the challenge of developing its first high-speed railway line, in response to the need to provide faster domestic and international transport alternatives. High-speed train passages on railway bridges can cause resonance in the bridge superstructure, which induce high accelerations that should not exceed the limits stipulated in the current design code.
