1. 1. Forced response numerical investigation of a transonic compressor rotor

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Mariana Pires Gonçalves Toco Dias; [2023]
   Keywords : Compressor; rotor; blisk; aeroelasticity; aerodynamic damping; CFD; transient; forced response;

   Abstract : The present thesis discusses the forced response of a rotor’s bladed-disk when excited by the periodic force produced by a wake generator, or Inlet Guide Vane (IGV),with 8 equally-spaced blades. These components are part of an axial transonic compressor rig, moreover the Transonic Compressor Darmstadt 1 (TCD1), located at the Technical University of Darmstadt. READ MORE

3. 2. Testing macroscopic traffic evacuation models for wildland-urban interface fires

   University essay from Lunds universitet/Avdelningen för Brandteknik

   Author : Adam Ardinge; [2021]
   Keywords : WUI-NITY; WUI; V V; traffic evacuation; WUI fire evacuation; simulation model; verification testing; validation testing; Kincade; Technology and Engineering;

   Abstract : This thesis presents the verification and validation testing performed on the evacuation simulation platform WUI-NITY which has the aim of being a simulation tool for the integration of different layers, such as pedestrian, traffic and wildfire with evolving dynamic interactions. The present thesis aims at applying a set of verification tests and validation testing suitable for WUI-NITY with a focus on the traffic component. READ MORE

4. 3. Value at Risk estimation : A comparison between different models

   University essay from Uppsala universitet/Statistiska institutionen

   Author : Mathias Mattsson; [2021]
   Keywords : CAViaR; GARCH; Value at Risk; Backtesting;

   Abstract : In this thesis the performance of the quantile based CAV iaR models is evaluated and compared with GARCH models for predicting the Value at Risk. This is done by one step ahead out of sample prediction. The one step ahead out of sample prediction is done for the 500 observations at the end of the sample. READ MORE

5. 4. Relating Process Data to Product Quality in Transmission Manufacturing

   University essay from KTH/Industriell produktion

   Author : Claudia Tensi; [2021]
   Keywords : ;

   Abstract : Research has shown that vibration produced by a machine tool provides useful information for the maintenance of its structural parts. Thus, the vibration signal should also give information about tool wear and, consequently, surface roughness of the machined workpieces. READ MORE

6. 5. Tiling heuristics and evaluation metrics for treemaps with a target node aspect ratio

   University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

   Author : Rodrigo Roa Rodríguez; [2017]
   Keywords : Treemap; heuristics; tiling; tessellation; metrics; aspect ratio; orientation agnostic; OAAR; FOAAR; orientation; offset factor; offset quotient; information visualization; infoviz; macro-economic metaphor; eat the poor; eat the rich; subsidy; welfare;

   Abstract : Treemaps are a popular space-filling visualization of hierarchical data that maps an attribute of a datum, or a data aggregate, to a proportional amount of area. Assuming a rectangular treemap consisting of nested rectangles (also called tiles), there are multiple possible valid tiling arrangements. READ MORE
